Summary This study was conducted to evaluate the adverse effects of the anabolic steroid, boldenone undecylenate (BOL) on reproductive functions of male rabbits. Thirty white New Zealand mature male rabbits were divided into three groups (10 rabbits each). Group A rabbits served as a control group. Group B rabbits received 4.4 mg/kg body weight (bwt) BOL 5% oily solution. Group C rabbits received 8.8 mg/kg bwt BOL. Rabbits were injected intramuscularly twice weekly for two months. BOL had no significant effect on the bwt and bwt gain. Testes and epididymis weights were decreased significantly in the BOL-treated groups. BOL caused significant reduction in serum testosterone level, seminal volume, sperm motility, and sperm count. No abnormalities were detected in the sperm morphology of the BOL-treated groups. Histopathological alterations in the testes and epididymis were marked in the group C rabbits. These results indicate that administration of BOL exerts a significant harmful effect on the reproductive functions of male rabbits. PMID:22583130

Background Strategies to improve communication in people with dementia are warranted. We examined the effect of the Sonas programme on communication ability in persons with moderate to severe dementia. Methods A 24-week 3-armed (Sonas, reading, and control group) randomized controlled trial including 120 nursing home residents with dementia was conducted; 105 completed the follow-up assessments. The main outcome was change in communication abilities measured by the Holden Communication Scale (HCS). Results We found no overall significant effect of the Sonas programme with regard to communication ability as measured by the HCS. However, an effect between the Sonas group and the reading group and between the Sonas group and the control group from T0 to T1 and T2 was found, as well as a significant improvement in communication in the Sonas group. Among people with severe dementia, the Sonas group scored significantly better on the HCS compared to the reading group after 12 weeks, but not after 24 weeks. Conclusion This study failed to document an overall effect of the Sonas programme on communication; however, the findings indicate that the Sonas programme has a significant effect on communication among those with severe dementia.

Depression is the most common mental illness among women. Its prevalence in women is two to three times that of men. The purpose of the present study was to evaluate the effectiveness of resilience training on the reduction of depression in female college students. This semi-empirical study was carried out with two experimental groups and one control group. The research sample was women with symptoms of depression who were 18-22 years of age and living in a college dormitory. One experimental group was given eight 90-minute resilience training sessions, while the other received eight 90-minute cognitive therapy sessions. The control group didn't receive any interventions. The three groups under study were evaluated using the Beck II depression inventory before and after the interventions and two months after the treatment had ended. The three groups didn't have significant differences in age, marital status, or depression scores on the pretest. The resilience training group and cognitive therapy group showed a significant decrease in the average depression score from pretest to posttest and from pretest to follow-up. The main effect of groups, stage, and interaction between groups and stage also were significant (all were p < 0.001). There was no significant difference between effectiveness of resilience training and cognitive therapy on depression but there was a significant difference between these two treatment groups and the control group. The effectiveness of resilience training was just as good as the effectiveness of cognitive therapy. The effects of resilience training on depression remained stable from the posttest to the follow-up, like that of cognitive therapy.

The goal of this study was to evaluate the protective and mitigative effect of vitamin C on oxidative stress in differentiated thyroid cancer (DTC) patients ablated with radioiodine. 58 DTC patients selected for radioactive iodine therapy (RAIT) with 5550 MBq 131 Iodine were divided into four groups. Group 1 (control group) consisted of patients who underwent RAIT routinely. Other patients received 1500 mg vitamin C daily 2 days after (group 2), 2 days before to 2 days after (group 3) and 2 days before RAIT (group 4). Serum oxidative stress markers including malondialdehyde (MDA), glutathione (GSH), catalase (CAT), and superoxide dismutase (SOD) were measured immediately before and 2 days after RAIT. A significant increase in MDA after RAIT was observed in all groups (p < 0.05). The concentrations of MDA were significantly higher in the control group compared to the intervention groups (p < 0.05). A significant decrease in the control group (p < 0.05) and increase in group 4 (p < 0.05) were observed in GSH level after RAIT (p < 0.05). Mean variation of GSH was significant between control group with groups 3 (p < 0.01) and 4 (p < 0.01). The results indicate that activity of SOD remained unchanged in all groups (p > 0.05). A significant increase was observed in CAT activity after RAIT in all groups (p < 0.05), which was higher in control group than intervention groups. In groups 3 (p < 0.05) and 4 (p < 0.05), this increase in CAT activity was significantly lower than the control group. RAIT causes serum oxidative stress, which can be ameliorated using vitamin C as an antioxidant. These results indicate that radioprotective effect of vitamin C is preferable to its mitigative effect.

This study was to evaluate the effects of foot reflexology on blood pressure, serum lipids level and life satisfaction in essential hypertension patients. The research design used was a nonequivalent control group pretest-posttest design. Foot Reflexology was used as the experimental treatment from June 23rd, 2003 until August 31st, 2003. Thirty-four subjects were assigned to an experimental group(18) and control group(16). Foot Reflexology was administered twice a week for 6 weeks and self foot Reflexology was administered twice a week for 4 weeks on the experimental group. There was a significant decrease in systolic blood pressure but no significant decrease in diastolic pressure in the experimental group compared to the control group. The total cholesterol level in the experimental group compared to the control group was not significantly decreased after foot reflexology. However, the triglyceride level in the experimental group compared to the control group was significantly decreased after foot reflexology. On the other hand, high density lipoprotein and low density lipoprotein levels in the experimental group compared to the control group was not significantly decreased after foot reflexology. Life satisfaction in the experimental group compared to the control group was significantly improved after foot reflexology. The results proved that foot reflexology was an effective nursing intervention to decrease systolic pressure, and triglyceride but not for the blood cholesterol and to improve life satisfaction. Therefore, blood cholesterol should be further evaluated in a larger group of subjects and for a longer period. Further research is regarded as necessary to evaluate and to compare effects of self-foot reflexology and foot reflexology.

The effects of a workplace design and training intervention and the relationships between perceived satisfaction of office workplace design factors (layout and storage) and work performance measures (individual performance, group collaboration and effectiveness) were studied with 120 office workers using the Workplace Environment Questionnaire. Further, we examined whether environmental control had a direct effect on work performance, and then explored whether environmental control mediated or moderated the relationship between workplace design factors and work performance. Results showed a significant, positive impact of the intervention on environmental satisfaction for workstation layout. Satisfaction with workstation layout had a significant relationship with individual performance, group collaboration and effectiveness; and satisfaction with workstation storage had a significant relationship with individual performance and group collaboration. Environmental control had a direct impact on individual performance and group collaboration; whereas, the mediating and moderating effects of environmental control on the relationship between workplace design factors and outcome variables were not significant.

To evaluate the effect of Supportan, an enteral nutrition (EN) specific for tumor patients, on the nutritional status and immune function of late-staged gastric cancer patients undergoing chemotherapy. Sixty-six late-staged gastric cancer patients undergoing chemotherapy were randomly divided into EN group (n=33) and control group (n=33). During chemotherapy, the patients in EN group received Supportan and the patients in the control group received basic diet. On the 14th day before chemotherapy and after chemotherapy, nutritional status and cell immune indicators were evaluated. As for nutrition indicators, there were no significant differences in EN group before and after chemotherapy (P > 0.05). Total protein, hemoglobin, prealbumin and transferrin significantly decreased after chemotherapy compared with those before chemotherapy in the control group (P< 0.01). The levels of CD4(+), CD8(+) T cells and CD4/CD8 were significantly increased, and NK cells, serum levels of IL-1, IL-6 were significantly decreased after chemotherapy in EN group (P< 0.01). The levels of IL-6 and TNF-alpha were significantly higher after chemotherapy than those before chemotherapy in the control group(P< 0.01). Curative effects of immune nutrition in EN group were superior to that in the control group, however, the differences were not statistically significant. The incidences of nausea, vomiting and marrow inhibition in Supportan group was lower compared with those in the control group, but with no significant difference. Supportan can prevent malnutrition of the late-staged gastric cancer patients undergoing chemotherapy, and improve immune function and alleviate adverse effects of chemotherapy.

To investigate the effect of Procyanidins (OPCs) on the autophagy of laryngeal cancer cell line TU686 and to explore the effect of OPCs on the chemosensitivity of laryngeal cancer cells to DDP in terms of autophagy and apoptosis. CCK-8 was used to detected the effect of different concentrations of OPC and DDP on TU686 cell viability. Experimental grouping: Both kinds of cells were divided into CON group, DDP group, OPC group and MIX group. Annexin-V-FITC/PI double staining of flow cytometry was used to detect the effect of each experimental group on the apoptosis. Cell immunofluorescence staining was used to detect the formation of autophagy. Western blot was used to detect the expression of autophagy-related and apoptosis-related proteins. Autophagy inhibitors (3-MA) were used to study the effect of autophagy on apoptosis. The results of CCK-8 showed that TU686 cells were inhibited by OPC and DDP in a concentration-dependent manner for 24 hours. LC3-Ⅱ protein staining showed that compared with CON group, DDP group and OPC group, MIX group significantly induced autophagy formation in TU686 cells ( P <0.05). Flow cytometry showed that compared with CON group, apoptosis of TU686 cells was induced in DDP group, OPC group and MIX group. And the effect of MIX on apoptosis was significantly higher than that of OPC and DDP groups ( P <0.05). After pretreatment with 3-MA, the apoptotic effect of OPC group and MIX group on TU686 cells was significantly decreased ( P <0.05). Western blot results showed that the expression of LC3-Ⅱ and Caspase-3 in DDP, OPC and MIX groups was significantly higher than that in CON group ( P <0.05). In MIX group, the expression of LC3-Ⅱ and Caspase-3 also had significant difference ( P <0.05) compared with single drug group. After using 3-MA to inhibit autophagy, the expression of LC3-Ⅱ was significantly decreased ( P <0.05), and the expression of Caspase-3 was decreased along with LC3-Ⅱ, but the decrease of Caspase-3 expression was only significant in OPC and MIX group ( P <0.05). OPC can induce autophagy in laryngeal carcinoma TU686 cells and promote its apoptosis, which in turn enhances sensitivity of laryngeal cancer cells to cisplatin chemotherapy.

Preoperative radiotherapy in colorectal cancers is being used as an adjuvant therapy with increasing frequency. Postoperative complications in early and late periods in various ratios are reported. It has also been shown that radiation has a delaying effect on wound healing and this effect is dose-dependent. This study investigated the effects of the Amifostine on healing of the irradiated colonic anastomosis. 30 female Wistar rats were divided randomly into three groups equally (n=10). Colonic anastomosis were performed to all rats. Group I served as a control. 800 rad abdominopelvic irradiation on the 5th day of preoperation was given to group II and III. Rats in the group III, prior to radiation, were given Amifostine at a dose of 200 mg/kg. On the 5th postoperative day all the rats were sacrificed and the healing of anastomosis was measured with bursting pressure, hydroxyproline levels and histopathological evaluations. Statistical analyses were expressed by analysis of variance (ANOVA) test and p < 0.05 was regarded as significant. In group II, all parameters were found lower compared with control group and Amifostine+Radiation group. As compared with hydroxyproline values and the anastomotic wound healing scores, except group II, no significantly difference were determined between the two other groups. In bursting pressure levels, Group I and III were higher than group II, but not statistically significant (p > 0.05). In group III (Amifostine+Radiation group), the hydroxyproline levels and anastomotic wound healing scores were found significantly higher than group II (p < 0.05), and no significant difference were found between the control group. It is determined that radiation given on the 5th preoperative day has a negative effect on anastomotic wound healing and administered Amifostine prevent this negative effect. In the light of these data, the Amifostine may have a positive effect on preoperative irradiated colonic anastomosis and may play an important role in future on the supporting of the colonic anastomosis.

The present study was designed to evaluate the effect of nanoselenium (Nano-Se) on hematological and biochemical parameters of rats experimentally intoxicated with lead (Pb). Thirty male rats were randomly divided into six groups as follows: the control, selenite, Nano-Se, Pb group, Pb + selenite, and Pb + Nano-Se groups. After 35 days, blood was collected from rats and hematology and serum biochemical parameters of oxidative stress were measured. The thiobarbituric acid reactive substances (TBARS) level of Pb group was significantly higher than other groups. Also, TBARS level was significantly lower in the Pb + Nano-Se group than Pb + selenite group. The serum superoxide dismutase activities were significantly lower in Pb group than the control, Pb + selenite, and Pb + Nano-Se groups. The catalase activities in the Pb group showed no significant change when compared to other groups. In the Pb group, packed cell volume was lower than the control group. A significant difference was observed between the control group and the Pb, Pb + selenite, and Pb + Nano-Se groups. In the Pb group, the numbers of white blood cell (WBC) decreased in comparison with the control group. Also, there was significant increase in WBC counts in the Pb + Nano-Se and Pb + selenite groups in comparison with Pb group. The number of lymphocytes in the Pb group decreased in comparison with the control group. By comparing the means of the Pb + Nano-Se and Pb + selenite groups together, it was determined that there were significant differences in the lymphocytes and neutrophil counts. In conclusion, usage of selenium compounds particularly Nano-Se particles inhibits the adverse effects of Pb on antioxidant activity and immune system function in the Pb poisoning.

To observe on the transient analgesic effect of abdominal points transcutaneous electrical nerve stimulation (TENS) combined with abdominal acupuncture according to the holographic theory on pain of neck, shoulder, loin and legs. One hundred and twenty cases of pain of neck, shoulder, loin and legs were randomly divided into 4 groups: abdominal acupuncture TENS group, acupoints TENS group, electroacupuneture (EA) group, non-abdominal acupuncture TENS group, 30 cases in each group. All the cases were treated by the same stimulation parameters, but different stimulation points. The VAS scores were recorded before and after treatment. The VAS scores were significantly different before and after treatment in abdominal acupuncture TENS group (P < 0.01); the total effective rate of the transient analgesic effec t was 96.7% in the abdominal acupuncture TENS group, 93.3% in the acupoints TENS group, 96.7% in the EA group with no significant difference among the 3 groups, but with a very significant difference between the abdominal acupuncture TENS group and the non-abdominal acupunctureTENS group (10.0%), P < 0.01. Abdominal acupuncture TENS has a better transient analgesic effect and can use less stimulation points to increase the analgesic effect.

Mindfulness as a mode of sustained and receptive attention promotes openness to each incoming stimulus, even if repetitive and/or aversive. Mindful attention has been shown to attenuate sensory habituation in expert meditators; however, others were not able to replicate this effect. The present study used acoustic startle reflex to investigate the effect of mindfulness practice intensity on sensory habituation. Auditory Startle Response (ASR) to 36 startling probes (12 trials x 3 block with 40 ms inter-block intervals), was measured using electromyography (EMG) in three groups of participants (N = 12/group): meditation-naïve, moderate practice, and intensive practice. Intensive practice group showed attenuated startle habituation as evidenced by significantly less habituation over the entire experiment relative to the meditation-naïve and moderate practice groups. Furthermore, there was a significant linear effect showing between-block habituation in meditation-naïve and moderate practice groups, but not in the intensive practice group. However, the Block x Group interaction between the intensive practice and the meditation-naive groups was not significant. Moderate practice group was not significantly different from the meditation-naïve in the overall measure of habituation, but showed significantly stronger habituation than both meditation-naïve and intensive practice groups in Block 1. Greater practice intensity was significantly correlated with slower overall habituation and habituation rate in Blocks 2 and 3 in the intensive, but not in the moderate, practice group. The study provides tentative evidence that intensive mindfulness practice attenuates acoustic startle habituation as measured by EMG, but the effect is modest.Moderate practice, on the other hand, appears to enhance habituation, suggesting the effect of mindfulness practice on startle habituation might be non-linear [corrected] . Better understanding of the effect of mindful attention on startle habituation may shed new light on sensory information processing capacity of the human brain and its potential for de-automatisation of hard-wired processes.

This study was designed to compare the analgesic effects of cryoanalgesia and parecoxib in lung cancer patients after lobectomy. A total of 178 lung cancer patients awaiting large-sized lobectomy were enrolled in the study. The patients were randomly divided into Group A (intercostal nerve cryoanalgesia) and Group B (parecoxib). The analgesic and adverse effects were compared between the two groups. The pain score of Group A was significantly lower than that of Group B (P < 0.05). The patients in Group A used significantly less morphine than those in Group B (P < 0.05). There were also significantly fewer complications in Group A than in Group B (P < 0.05). Cryoanalgesia of the intercostal nerves can be considered an economical, safe and simple technique for the long-term management of post-lobectomy pain.

To compare therapeutic effects of low frequency pulse plus auricular point magnetic therapy and prepulsid on functional dyspepsia (FD). Fifty cases of FD were randomly divided into a treatment group and a control group. The treatment group were treated with low frequency pulse stimulation on Zhongwan (CV 12), Weishu (BL 21), Neiguan (PC 6), Zusanli (ST 36), with Fenglong (ST 40) and Sanyinjiao (SP 6) selected according to syndrome differentiation, once a day, 30 min each session. The control group were treated with oral administration of prepulsid. Five days constituted one course. The scores of symptoms and parameters of electrogastrogram (EGG) before and after treatment and the therapeutic effect were investigated. After treatment, the symptom scores significantly decreased (P < 0.01), with a significant difference in the decrease of symptom scores between the two groups (P < 0.05); and EGG parameters were improved (P < 0.05). The total effective rate of 93.3% in the treatment group was better than 75.0% in the control group with a significant difference between the two groups (P < 0.05). Low frequency pulse plus auricular point magnetic therapy can significantly improve the clinical symptoms and gastric activities in the patient of FD, with a better therapeutic effect than prepulsid.

A twelve-week controlled intervention trial was carried out to evaluate the effects of combined physical activity and dietary intervention on obesity and metabolic risk factors among employees of Universiti Putra Malaysia. Participants consisted of adults aged 25-55 years with no reported chronic diseases but with abdominal obesity. They were assigned to either a combined physical activity and dietary intervention group or a control group. The final sample consisted of 56 participants, with an equal number of 28 for each study group. No significant group effect was observed for any variable except for hip circumference (HC) and fasting plasma glucose (FPG). There was a significant increase in HC (p=0.007) and reduction in FPG (p=0.02) in the intervention group compared to the control group. In the intervention group, HC (p=0.002), triglycerides (TG) (p=0.0001), total cholesterol (TC) (p=0.0001), LDL cholesterol (LDLC) (p=0.0001) and FPG (p=0.005) were significantly reduced, while waist circumference (WC) (p=0.025) and the waist-to-hip ratio (WHR) (p=0.027) were significantly reduced in the control group. No significant change in steps/day or calorie intake'was observed in either group. Taken together, these data indicate that the combined physical activity and dietary intervention was not effective at improving diet or physical activity level. However, the intervention was effective in improving FPG among participants with abdominal obesity. The significant increase in HC in the interventions group warrants further study. These findings will be useful to further improve group-based intervention for the prevention and management of obesity.

Objective: To evaluate the therapeutic effects of probiotics on neonatal jaundice and the safety. Methods: Sixty-eight neonates with jaundice were divided into a control group and a treatment group (n=34) randomly, and treated by blue light phototherapy and that in combination with probiotics. The serum bilirubin levels were detected before and 1, 4, 7 days after treatment. The time when therapy showed effects and jaundice faded, clinical outcomes as well as adverse reactions were recorded. The categorical data were expressed as (±s) and compared by t test. The numerical data were expressed as (case, %) and compared by χ² test. P<0.05 was considered statistically significant. Results: Serum bilirubin levels of the two groups were similar before treatment (P>0.05). The levels significantly decreased 1, 4 and 7 days after treatment (P<0.05), but there was no significant inter-group difference on the post-treatment 1st day (P>0.05). The treatment group underwent more significant decreases on the 4th and 7th days than the control group did (P=0.002, 0.001). In the treatment group, the therapy exerted effects on (1.0±0.5) d and jaundice faded on (3.8±1.7) d, which were (2.6±0.6) d and (5.3±2.1) d respectively in the control group (P=0.001, 0.002). The effective rate of the treatment group significantly exceeded that of the control group (P=0.002). There were no obvious adverse reactions in either group. Conclusions: Probiotics lowered the serum bilirubin levels of neonates with jaundice rapidly, safely and significantly, and accelerated jaundice fading as well. This method is worthy of application in clinical practice. PMID:26649008

The aim of the study was to explore the effects of different fitness sports on cognitive function and emotion of the aged people. A total of 150 subjects aged between 60 and 70 were recruited from Shenyang Aged University and elderly activity center. All subjects reported no fitness before this study. The aged subjects were divided into five groups, included swimming group (A group), running group (B group), square dancing group (C group), Tai Chi group (D group) and control group (E group) with 30 people in each group. Subjects in each group received exercise intervention continued for 18 months. At baseline, 6, 12 and 18 months after intervention, the P300 test, SECF, HAMD and HAMA scale evaluations were performed. Compared to E group, the P2, N2 and P3 latency and response time in the D group after intervention for 6 months, and in the A-C groups after intervention for 12 months were significantly prolonged. The anxiety symptom and depression levels in the A-D groups after intervention for 12 months were significantly decreased when compared to E group (P < 0. 01), where significantly improved compared with the E group (P < 0. 01). The effect of exercise intervention for Tai Chi group was the most significant. Different fitness sports have marked beneficial effect on cognitive function and emotion of the aged people, especially the Tai Chi exercise.

The purpose of this study was to identify changes taking place in the rat testis at the 24th hour of reperfusion following testicular torsion and to evaluate the effects of resveratrol (RSV), a powerful antioxidant, in preventing these changes using novel biochemical parameters and histopathology. Eighteen adult male rats were divided into three groups: Sham-operated (S), torsion/detorsion (T/D), and T/D+RSV groups. In the T/D group, testicular ischemia was achieved by rotating the left testis 720° clockwise for 4h. In the T/D+RSV group, 20mg/kg RSV was administered intraperitoneally 30 min before detorsion. All rats were sacrificed 24h after detorsion. Serum and tissue malondialdehyde (MDA) concentrations, ischemia modified albumin (IMA), total oxidative status (TOS), total antioxidant status (TAS), oxidative stress index (OSI), and histopathological damage score were analyzed. Serum MDA, IMA, TOS, and OSI levels rose significantly in the T/D group. Serum MDA and IMA values were lower in the T/D+RES groups, but not significantly. OSI and TOS values were lower in the T/D+RES group, and the difference was significant. TAS values decreased significantly in the T/D group and rose in the T/D+RSV group, but not significantly. Ipsilateral tissue MDA values were significantly elevated in the T/D group and decreased in the T/D+RSV group, but not significantly. Apoptosis and histopathological damage increased significantly in the T/D group and decreased significantly in the T/D+RSV group. In the contralateral testis, apoptosis increased significantly in the T/D group. It decreased significantly in the T/D+RSV group. Our findings show that RSV had a protective effect against oxidative damage induced with a testicular T/D model, especially at the antiapoptotic and histopathological level. OSI may be a good guide to the clinical status of testicular T/D. © 2014.

Different types of ipriflavone (IF) have been reported to be effective when used as a remedy for bone loss due to osteoporosis. However, no information is available regarding the relationship between IF and jaw bone structure. The aim of this study was to examine the effect of IF on rat mandibles during the growth stage. Thirty-two 5-week-old Wistar male rats were divided into four groups. The control group was fed a standard diet, group A received a low calcium diet (calcium content 30 per cent of the standard diet) for 6 weeks, and the other two groups were fed a low calcium diet for 3 weeks and then a standard diet without IF (group B) or with IF (group C) for 3 weeks. In addition, distilled water was provided for all groups. The effects of IF on mandibular size and bone mineral content were investigated, using lateral cephalometric analysis and peripheral quantitative computed tomography (pQCT). For mandibular length, the control group showed a significantly higher value than groups A and B (P < 0.01, P < 0.05, respectively), while group C demonstrated a significantly higher value than group A (P < 0.01). In addition, the control group and group C showed significantly higher values for mandibular ramus height than group A (P < 0.01). However, bone mineral density in trabecular bone was significantly higher in the control group than in the other groups (P < 0.01) and bone mineral density in cortical bone was significantly higher in the control group than groups A, B and C (P < 0.01, P < 0.01, P < 0.05, respectively). Bone mineral density in both trabecular and cortical bone was significantly higher in group C than in groups A and B (P < 0.01, P < 0.05, respectively). These results indicate that complete recovery from calcium deficiency to the level of the control group may not be attainable, even though IF enhances calcium absorption to act on bone cells and promote bone construction. The importance of calcium intake in the early stages of development was confirmed. These findings also suggest an effect of IF on jaw bone structure.

Infusion phlebitis is the most common side effect of clinical intravenous drug therapy and several clinical studies have demonstrated that anisodamine can effectively prevent the occurrence of infusion phlebitis. This study was designed to investigate effects of anisodamine on the expressions of vascular endothelial growth factor (VEGF) and intercellular adhesion molecule 1 (ICAM-1) in a rabbit model of infusion phlebitis and to analyze the mechanisms of anisodamine effect on the prevention and treatment of experimental infusion phlebitis. Twenty-four specific pathogen-free male Japanese white rabbits were randomly assigned to the control group, the model group, the magnesium sulfate group and the anisodamine group. The rabbit model of infusion phlebitis, induced by intravenous administration, was established and expressions of VEGF and ICAM-1 were determined and contrasted with the control group treated with normal saline. We evaluated expression by histopathology, immunohistochemistry, reverse transcription-polymerase chain reaction, and Western blotting assay. Pathohistological changes of the model group were observed, such as loss of venous endothelial cells, inflammatory cell infiltration, edema and thrombus. The magnesium sulfate group and the anisodamine group showed significant protective effects on vascular congestion, inflammatory cell infiltration, proliferation, swelling of endothelium and perivascular hemorrhage. The model group showed the highest expressions of VEGF and ICAM-1 of the four groups (P < 0.01). On the contrary, anisodamine alleviated the inflammatory damage by significantly reducing the expressions of VEGF and ICAM-1 compared with the model group (P < 0.01). There was no significant difference in the expressions of VEGF and ICAM-1 between the magnesium sulfate group and the anisodamine group (P > 0.05). Anisodamine alleviates inflammatory damage by significantly reducing the expressions of VEGF and ICAM-1, and shows significant protective effects in an animal model of infusion phlebitis.

Ebselen is used as a drug in clinical trials against stroke, reperfusion injury with anti-atherosclerotic and renoprotective effects. The aim of this study is to investigate the protective effect of ebselen, on torsion/detorsion (T/D)-induced biochemical and histopathological changes in experimental testicular ischaemia/reperfusion injury. A total of 28 male Wistar Albino rats were divided into four groups: group 1(sham-operated group, n = 7), group 2(ebselen group, n = 7), group 3(torsion/detorsion + saline, n = 7) and group 4(T/D + 10 mg kg(-1) ebselen group, n = 7). The tissue homogenate samples were used for immediate nitric oxide (NO), malondialdehyde (MDA), superoxide dismutase, catalase and glutathione measurement. Testes in all groups were evaluated for the biochemical assay and histopathological examinations. To evaluate spermatogenesis, Johnsen scoring system was used. Testicular tissue MDA and NO levels in group 3 were significantly higher than in group 1 and 4. In histological evaluation of the testicular tissues, ebselen administration improved tubular histology significantly compared with T/D group. Significant increase in histological score was observed in the testis of group 3 compared with group 1 and 2. Histological score in group 4 significantly decreased compared with group 3. Johnson score was significantly lower in T/D group compared with all other three groups, ebselen administration increased the score significantly compared with T/D group. Ebselen reduced oxidative biochemical and histopathological damage in our testicular T/D rat model. © 2013 Blackwell Verlag GmbH.

To observe the effects of high +Gx during simulated spaceship emergency return on learning and memory in rats. Thirty two male SD rats were randomly divided into control group, 7 d simulated weightlessness group, +15 Gx/180 s group and +15 Gx/180 s exposure after 7 d simulated weightlessness group, with 8 rats in each group. The changes of learning and memory in rats were measured after stresses by means of Y-maze test and step-through test. In Y-maze test, as compared with control group, percentage of correct reactions decreased significantly (P<0.01) and reaction time increased significantly (P<0.01) in hypergravity after simulated weightlessness group at all time after stress; as compared with +15 Gx group or simulated weightlessness group, percentage of correct reactions decreased significantly (P< 0.05) and reaction time increased significantly (P< 0.05) immediately after stress. In step-through test, as compared with control group, total time increased significantly (P<0.01) in hypergravity after simulated weightlessness group at 1 d after stress; latent time decreased significantly (P<0.01) and number of errors increased significantly (P< 0.01) at all the time after stress. As compared with +15 Gx group, total time increased significantly (P<0.05) immediately, 1 d after stress. As compared with simulated weightlessness group, total time and number of errors increased significantly (P<0.05) immediately after stress. It is suggested that +15 Gx/180 s and simulated weightlessness may affect the ability of learning and memory of rats. Simulated weightlessness for 7 d can aggravate the effect of +Gx on learning and memory ability in rats.

Differential effect of Pistacia vera extracts on experimental atherosclerosis in the rabbit animal model: an experimental study

PubMed Central

2010-01-01

Background Lipid-enriched diets and oxidative stress are risk factors for the development of atherosclerosis. The effects of the methanolic (ME) and cyclohexane (CHE) extracts of the Pistacia vera nut, often included in the Mediterranean diet, were studied in the rabbit model of atherosclerosis. Methods and results Twenty-four New Zealand White rabbits received atherogenic diet (Control Group), supplemented with ME (Group ME) or CHE (Group CHE) for 3 months. Previously, a GC-MS and a UHPLC LC-DAD-ESI(-)-HRMS/MS method were developed to investigate the extracts' chemical profiles. Blood samples at baseline and monthly determined lipid profile, lipid peroxidation and liver function. The aorta, myocardium and liver were examined histologically at 3 months. Groups ME and CHE had significantly higher HDL- and non-significantly lower LDL-cholesterol median % changes from baseline than the Control Group. Triacylglycerol was significantly higher in Group CHE vs. Control. MDA values were significantly lower in Group ME vs. Control and CHE. ALT and AST were significantly higher in Group CHE vs. Control. γ-GT was lower in Group ME vs. Control. Aortic intimal thickness was significantly less in Groups ME and CHE vs. Control; Group ME atherosclerotic lesions were significantly less extensive vs. Groups Control and CHE. Only Group CHE had significant liver fatty infiltration. Conclusions During short-term administration concomitantly with atherogenic diet, both P. vera extracts were beneficial on HDL-, LDL-cholesterol and aortic intimal thickness. The ME additionally presented an antioxidant effect and significant decrease of aortic surface lesions. These results indicate that P. vera dietary inclusion, in particular its ME, is potentially beneficial in atherosclerosis management. PMID:20633299

Our goal was to document effects of year-round supplemental feeding on breeding ecology of the Buff-throated Partridge, Tetraophasis szechenyii, within a Tibetan sacred site. We evaluated effects of supplemental feeding used as religious/cultural practices which could potentially aid conservation of endangered phasianids. We compared fed breeding groups to neighboring nonfed groups. Fed groups initiated first clutches significantly earlier than nonfed groups. Earlier laying groups within fed and nonfed groups showed significantly lower hatching rates than later groups; however, fed groups showed significantly higher hatching rates than nonfed groups laying in the same period. Earlier laying increased opportunities to renest. All six fed groups with clutch failures renested compared to only one of five nonfed groups with clutch failures. Fed female breeders showed significantly greater investment in their young with larger clutches and larger eggs, which likely increased survivability of early hatchlings. We observed no predation on birds at feeding sites and recorded only four cases of predation on incubating females, which showed no detectable difference between fed and nonfed groups. Ground-nesting birds typically face high risks of predation. Ten of the 48 groups nested in trees, which occurs in few phasianid species. Tree nests showed significantly higher hatching rates compared to ground nests; however, we found no significant difference in tree nesting between fed and nonfed groups. This partridge is one of four gallinaceous species with cooperative breeding. Breeding groups with helpers had significantly greater reproductive success than single pairs, and fed female breeders with helpers laid bigger eggs than single pairs. Comparing annual reproductive output per group, fed groups not only produced significantly more independent young (≥ 150 days post-hatching), their young hatched significantly earlier, which likely have greater reproductive value over later hatched young of nonfed groups. Supplemental feeding year-round is likely what enabled the successes of the fed partridges.

To compare effective phacoemulsification time in cataract surgery performed by manual phacoemulsification vs femtosecond laser-assisted lens fragmentation. Retrospective, consecutive, nonrandomized, comparative case series. The setting was the Department of Ophthalmology, Goethe-University, Frankfurt, Germany. The study population included 150 eyes of 86 patients with senile cataract. In the intervention, 88 eyes (group 1) underwent femtosecond laser-assisted surgery (corneal incisions, capsulotomy, lens fragmentation) using the LenSx platform (Alcon) and residual lens work-up with pulsed ultrasound energy (Infiniti Vision System; Alcon). In 62 eyes (group 2), complete cataract removal was performed with phacoemulsification only, using pulsed ultrasound energy with the same device (Infiniti). Nucleus staging (Pentacam nucleus staging; PNS) was evaluated using Pentacam HR (Oculus); endothelial cell density was measured using specular microscopy (NonCon Robo). The main outcome measures were as follows. Mean preoperative PNS staging was assessed using an automatic ordinal scaling (PNS-O, grades 0-5) and a manually defined density grid derived from Scheimpflug imaging (PNS-P [%]). Effective phacoemulsification time and endothelial cell loss were evaluated in both groups. Preoperative PNS-O and PNS-P showed no significant difference between groups (P = 0.267). Overall mean effective phacoemulsification time was significantly lower in group 1 (1.58 ± 1.02 seconds) compared to 4.17 ± 2.06 seconds in group 2 (P = 0.001). Effective phacoemulsification time was significantly lower in group 1 for all PNS-O stages (P < 0.001). With increasing preoperative PNS-P, effective phacoemulsification time increased in both groups; however, this gain was noticeably, but not significantly, lower in group 2. Endothelial cell loss was significantly lower in group 1 (P = 0.02). Femtosecond laser-assisted cataract surgery allows a significant reduction in effective phacoemulsification time, which correlates positively with the preoperative lens opacity.

Adenosine is an effective treatment for androgenetic alopecia (AGA) in Japanese men and women. Adenosine exerts its effects by significantly increasing the proportion of thick hair. In this study, we assessed the clinical outcome of adenosine treatment for 6 months in 38 Caucasian men. The change in proportion of thick hair (≥60 μm) compared with baseline in the adenosine group was significantly higher than that in the placebo group (P < 0.0001). The change in vellus hair proportion (<40 μm) was significantly lower in the adenosine group than that in the placebo group (P = 0.0154). The change in hair density compared with baseline of the adenosine group was also significantly higher compared with that of the placebo group (P = 0.0470). No adverse effects due to treatment were noted during this study by dermatological evaluation. Adenosine is effective in increasing the proportion of thick hair in Caucasian men with AGA as well as in Japanese men and women. © 2015 Japanese Dermatological Association.

Subjects with high plaque and gingivitis scores can profit most from the introduction of new manual or powered tooth brushes. To improve their hygiene, not only the technical characteristics of new brushes but also the learning effect in efficient handling are of importance. : The present study compared the efficacy in plaque removal of an electric and a manual toothbrush in a general population and analysed the learning effect in efficient handling. Eighty healthy subjects, unfamiliar with electric brushes, were divided into two groups: group 1 used the Philips/Jordan HP 735 powered brush and group 2 used a manual brush, Oral-B40+. Plaque index (PI) and gingival bleeding index (GBI) were assessed at baseline and at weeks 3, 6, 12 and 18. After each evaluation, patients abstained from oral hygiene for 24 h. The next day a 3-min supervised brushing was performed. Before and after this brushing, PI was assessed for the estimation of the individual learning effect. The study was single blinded. Over the 18-week period, PI reduced gradually and statistically significantly (p<0.001) in group 1 from 2.9 (+/-0.38) to 1.5 (+/-0.24) and in group 2 from 2.9 (+/-0.34) to 2.2 (+/-0.23). From week 3 onwards, the difference between groups was statistically significant (p<0.001). The bleeding index decreased in group 1 from 28% (+/-17%) to 7% (+/-5%) (p<0.001) and in group 2 from 30% (+/-12%) to 12% (+/-6%) (p<0.001). The difference between groups was statistically significant (p<0.001) from week 6 onwards. The learning effect, expressed as the percentage of plaque reduction after 3 min of supervised brushing, was 33% for group 1 and 26% for group 2 at week 0. This percentage increased at week 18 to 64% in group 1 and 44% in group 2 (difference between groups statistically significant: p<0.001). The powered brush was significantly more efficient in removing plaque and improving gingival health than the manual brush in the group of subjects unfamiliar with electric brushes. There was also a significant learning effect that was more pronounced with the electric toothbrush.

Striae distensae are very common cutaneous disorders that produce great psychological stress for women. measure and compare between efficacy and tolerability of three modalities for treatment of striae distensae. Forty-five female patients with striae distensae were randomly selected from the outpatient dermatology clinics of Al-Zahra university Hospital within 6 months period. Patients divided into three groups according to the therapeutic modalities were used. Group A: treated with carboxytherapy using carbon dioxide (CO2) injection, Group B: where patients were treated with intradermal injection of autologous platelet-rich plasma (PRP), and Group C: where we used tripolar radiofrequency (RF) for treatment. All treated groups showed overall clinical improvement as regards the width, texture, and overall improvement after treatment (P > .05), with no statistically significant differences between the three groups. Patient's satisfaction was statistically significantly better in both group C (93.33%) and group A (80%) while group B (53.33%) was less with minimal side effects such as pain and ecchymosis, which were more frequent in group B than the other two groups; but with no statistically significance differences both groups A and C were effective with no significant differences in both types of striae and in any site of the body but group B is significantly more effective on striae rubra on trunk, with better improvement of lesions texture. The three modalities of treatments proved to be effective clinically and histopathologically in treating both types of striae, which were well tolerated by the patients with minimal, transient side effects and our study results gave us guidelines for their clinical application. © 2018 Wiley Periodicals, Inc.

Mumijo (shilajit) has been well known in traditional medicine as a remedy for a number of diseases, such as bone fractures, wounds, inflammation, and headache. It is also widely used as an analgesic agent in folk medicine, but no scientific documentation exists concerning that effect. The current study was conducted to evaluate the ability of mumijo to reduce sensitivity to painful stimuli when compared with morphine sulfate and sodium diclofenac. A total of 176 animals were randomly and equally divided into 2 groups with 88 mice each-one for formalin test and the other for writhing test. For each test, the animals were allocated into 10 equal groups, based on the dosage of the analgesic, plus a negative control group, with 8 mice in each group. The analgesic effect of mumijo extract in doses of 0.75, 7.5, 75, and 750 mg/kg was assessed and compared witha group receiving distilled water-the negative control group, and that for groups receiving 1, 2, or 4 mg/kg of morphine sulfate or 10, 20, or 30 mg/kg of sodium diclofenac-the positive control groups. The results showed a significant decrease in pain intensity for all mice receiving doses of mumijo extract during a 1-h formalin test when compared with the distilled water group. For all the mumijo groups except the one receiving 750 mg/kg, the analgesic effect was significantly lower than that for the morphine sulfate group receiving 4 mg/kg. No significant differences existed between all mumijo and all diclofenac groups. In a writhing test, a significant inhibition of the pain response induced by acetic acid also occurred in all 4 mumijo-administered groups as opposed to the group receiving distilled water. No significant differences existed between the writhing response in groups receiving 75 and 750 mg/kg of mumijo and any doses of diclofenac or morphine. The comparison among the different doses of mumijo in the formalin test did not show any significant differences, but in the writhing test, the maximum dose showed a more effective analgesic action. The findings indicated a significant analgesic effect for mumijo extract on chronic pain in mice, occurring in a dose-independent manner.

To investigate the clinical effect of Gushen Antai pills and progesterone in the treatment of threatened abortion, in order to provide references for early clinical intervention with threatened abortion. The 112 cases of patients with threatened abortion were randomly divided into the control group and the observation group. 56 cases in each group. Patients in the control group was injected with progesterone, the observation group was treated with Gushen Antai pills in addition to the therapy of the control group. Both groups were treated by drugs for two weeks. Their venous bloods (5 mL) were collected before treatment and in 1, 2 weeks after treatment to determine serum levels of β-HCG, P, E2 and CA125. The differences between the two groups after treatment were compared. The total effective rate of the control group and the observation group were 79% and 91.9% respectively, with a statistically significant difference between the two groups (P＜0.05). Two weeks after the treatment, the serum levels of P and E2 in the observation group were significantly higher than before treatment, but the serum CA125 levels decreased significantly after treatment (P<0.05). These indicators showed statistically significant difference compared with that of the control group (P<0.05). After treatment, the serum β-HCG levels of the two groups were significantly higher than before treatment (P<0.05), but there was no statistically significant difference between the two groups. Gushen Antai pills and progesterone had a better clinical curative effect in treatment threatened abortion, which could significantly raise serum β-HCG, P and E2, reduce serum CA125 and increase the tocolysis efficiency, and so it was worth promoted in clinic.

This study was designed to investigate the antioxidant effects of Naringin, in ischemia/reperfusion (I/R)-induced skeletal muscle injury in rats. The rats were randomly allocated into three groups including control, I/R and I/R + Naringin groups. Muscle tissues of I/R groups revealed significantly higher antioxidant enzyme activities, and increased levels of malondialdehyde, as specific a marker of the lipid peroxidation and tissue damage, compared to the control group (p < 0.05). Levels of these parameters in muscle revealed significant reductions in the I/R + Naringin group compared to the I/R group (p < 0.05). Histopathological examination of ischemia muscles in the I/R group showed significant degeneration and inflammation compared to the control group, whereas ischemic muscles of Naringin-administered group showed significant reduction in degeneration and inflammation compared to the I/R group (p < 0.05). We suggest that the protective effect of Naringin may reduce the I/R injury in cases of extremity injuries with acute vascular complications, extremity surgery with prolonged tourniquet application.

The pain following gynecological laparoscopic surgery is less intense than that following open surgery; however, patients often experience visceral pain after the former surgery. The aim of this study was to determine the effects of preemptive ketamine on visceral pain in patients undergoing gynecological laparoscopic surgery. Ninety patients undergoing gynecological laparoscopic surgery were randomly assigned to one of three groups. Group 1 received placebo. Group 2 was intravenously injected with preincisional saline and local infiltration with 20 mL ropivacaine (4 mg/mL) at the end of surgery. Group 3 was intravenously injected with preincisional ketamine (0.3 mg/kg) and local infiltration with 20 mL ropivacaine (4 mg/mL) at the end of surgery. A standard anesthetic was used for all patients, and meperidine was used for postoperative analgesia. The visual analogue scale (VAS) scores for incisional and visceral pain at 2, 6, 12, and 24 h, cumulative analgesic consumption and time until first analgesic medication request, and adverse effects were recorded postoperatively. The VAS scores of visceral pain in group 3 were significantly lower than those in group 2 and group 1 at 2 h and 6 h postoperatively (P<0.05 and P<0.01, respectively). At 2 h and 6 h, the VAS scores of incisional pain did not differ significantly between groups 2 and 3, but they were significantly lower than those in group 1 (P<0.01). Groups 1 and 2 did not show any differences in visceral pain scores at 2 h and 6 h postoperatively. Moreover, the three groups showed no statistically significant differences in visceral and incisional pain scores at 12 h and 24 h postoperatively. The consumption of analgesics was significantly greater in group 1 than in groups 2 and 3, and the time to first request for analgesics was significantly longer in groups 2 and 3 than in group 1, with no statistically significant difference between groups 2 and 3. However, the three groups showed no significant difference in the incidence of shoulder pain or adverse effects. Preemptive ketamine may reduce visceral pain in patients undergoing gynecological laparoscopic surgery.

The aim of the current study was to evaluate the effect of pelvic floor muscle training in men with poststroke lower urinary tract symptoms. Thirty-one poststroke men, median age 68 years, were included in this single-blinded randomized controlled trial. Thirty participants, 15 in each group, completed the study. The intervention consisted of 3 months (12 weekly sessions) of pelvic floor muscle training in groups and home exercises. The effect was evaluated by the DAN-PSS-1 (Danish Prostate Symptom Score) questionnaire, a voiding diary, and digital anal palpation of the pelvic floor muscle. The DAN-PSS-1, symptom score indicated a statistical significant improvement ( p < .01) in the treatment group from pretest to posttest, but not in the control group. The DAN-PSS-1, total score improved statistically significantly in both groups from pretest to posttest (treatment group: p < .01; control group: p = .03). The median voiding frequency per 24 hours decreased from 11 at pretest to 7 (36%; p = .04) at posttest and to 8 (27%; p = .02) at follow-up in treatment group, although not statistical significantly more than the control group. The treatment group but not the control group improved statistically significantly in pelvic floor muscle function ( p < .01) and strength ( p < .01) from pretest to posttest and from pretest to follow-up ( p = .03; p < .01). Compared with the control group the pretest to posttest was significantly better in the treatment group ( p = .03). The results indicate that pelvic floor muscle training has an effect for lower urinary tract symptoms, although statistical significance was only seen for pelvic floor muscle.

To study the hypoglycemic effect of composite rice flour, the diabetic mouse model was established through the intraperitoneal injection of alloxan saline (twice, 200 mg/kg bw). The mice were randomly divided into 4 groups: negative control, positive control, metformin medication group, and composite rice flour feed group. After 21 days, the fasting blood glucose levels were determined by glucose oxidase method and followed with a glucose tolerance test. The results show that the body weight growth rate of mice in the rice flour group was significantly higher than that of the medication group (P < 0.01). Comparing with the positive control group, the fasting blood glucose levels of medication group and rice flour group were significantly lower, and the glucose tolerance was significantly increased in rice flour group (P < 0.01). In conclusion, the composite rice flour has obvious hypoglycemic and protective effect for diabetic mouse model.

Abstract The present study was examined the effects of xylitol feeding on diabetes-associated parameters in nondiabetic rats. Seven-week-old male Sprague-Dawley rats were randomly divided into three groups: control (five rats), sucrose (six rats), and xylitol (six rats). Animal had free access to a commercial rat pellet diet, and ad libitum water, 10% sucrose solution, and 10% xylitol solution were supplied to the control, sucrose, and xylitol groups, respectively. After 3 weeks of feeding of experimental diets, food intakes were significantly (P<.05) lower in the sucrose and xylitol groups compared with the control group. Drink intake was significantly higher in the sucrose group but significantly lower in the xylitol group compared with the control group. Body weight gain was significantly lower in the xylitol group compared with the sucrose group. Weekly nonfasting blood glucose was significantly increased, but fasting blood glucose was significantly decreased, in the sucrose group compared with the control and xylitol groups. Significantly better glucose tolerance was observed in the xylitol group compared with the control and sucrose groups. Serum insulin and fructosamine concentrations were not significantly influenced by the feeding of xylitol or sucrose. Relative liver weight and liver glycogen were significantly increased in the xylitol group compared with the sucrose group, whereas no difference was observed between the xylitol and control groups. Serum total cholesterol and low-density lipoprotein-cholesterol were significantly decreased in the sucrose and xylitol groups, and serum triglyceride of the xylitol group, but not the sucrose group, was significantly increased compared with the control group. Data of this study suggest that xylitol can be a better sweetener than sucrose to maintain diabetes-related parameters at a physiologically safer and stable condition.

Investigate the presence of Lactobacillus reuteri in saliva after supplementation with L. reuteri and the probiotic effect of L. reuteri on plaque index and supra- and subgingival microbiota. The study included 23 healthy individuals, randomised into test or control subjects. At baseline and after 12 weeks saliva samples, plaque index and supra- and subgingival plaque samples were obtained. The test subjects were given the study product (containing L. reuteri, ATCC 55730 and ATCC PTA 5289) and the control subjects placebo for 12 weeks. Microbiological analyses were done by checkerboard DNA-DNA hybridization technique and selective culturing for lactobacilli determination. A significant increase in total Lactobacillus counts in saliva occurred in both groups (p < 0.05) with a significant increase of L. reuteri (p = 0.008) in the test group.Termination of intervention resulted in a wash out of L. reuteri. The control group demonstrated a statistically significant increase in PII after 12 weeks (p = 0.023) whilst there was no significant change in the test group. A significant increase was found for most bacterial species in both groups in supra- and subgingival plaque with no significant difference for any of the species between the groups. The ratio between "bad/good" supragingival bacteria decreased for the test group but this decrease did not reach significance. The corresponding ratio for subgingival bacteria decreased significantly in both groups. Supplementation of L. reuteri resulted in presence of L. reuteri in saliva but L. reuteri was washed out after termination of intervention. No significant effect on supra- or subgingival microbiota was observed. The significant increase in PII in the control group with no significant change in the test group may, however, indicate a probiotic effect of L. reuteri in this study population.

[Purpose] The purpose of this study was to assess the effect of whole-body vibration exercise and plyometric exercise on female volleyball players. [Subjects and Methods] Subjects were randomly allocated to two exercise groups (whole-body vibration exercise group and plyometric exercise group). The exercise was conducted three times each week for 8 weeks. Isokinetic muscular strength, jumping performance, and balance were measured before starting the exercise and after finishing the 8 weeks of exercise. [Results] Measurements of isokinetic muscular strength revealed that the whole-body vibration exercise group showed significant increase after the exercise. However, the plyometric exercise group had no significant increase in lumbar flexion, extension, and knee flexion. Measurements of vertical jumping revealed that, the whole-body vibration exercise group had no significant increase after the exercise. However, the plyometric exercise group showed significant increase. Measurements of balance revealed that, the whole-body vibration exercise group showed significant increase. However, the plyometric exercise group showed no significant increase. [Conclusion] Although both whole-body vibration and plyometric exercises are effective intervention methods, the two methods have different effects on the improvement of isokinetic muscular strength, jumping performance, and balance of female volleyball players.

Cyclophosphamide (Cyc) is known to cause ovotoxicity and infertility in women. Our aim is to investigate the possible ovotoxic effects of Cyc and possible antioxidant and protective effects of blue-green algae, Spirulina (Sp), in rat ovaries. Eighteen rats were given: group I (n = 6, control); group II (n = 6, CP), a single dose Cyc; group III (n = 6, Sp+Cyc), 7 days Sp+single dose Cyc. Tissue malondialdehyde (MDA) levels, superoxide dismutase (SOD), and catalase (CAT) activities are assessed biochemically. Normal and atretic primordial and primary follicle counts for all sections obtained for each ovary are calculated. Mean number of follicle counts for each group are compared. In Sp+Cyc group, tissue MDA levels were significantly lower than those in the CP and higher than those in the C group (CP > Sp+Cyc > C). Tissue SOD activity was significantly higher in Sp+Cyc group than that in the CP group and lower than that in the C group (C > Sp+Cyc > C). No statistically significant difference was found between the ovarian CAT activities in any group. Histomorphometrically, there was also no significant difference between the mean numbers of normal and atretic small follicle counts. Our results suggest that single dose Cyc has adverse effects on oxidant status of the ovaries and Sp has protective effects in Cyc-induced ovotoxicity. PMID:23762559

Maximum sustained phonations of the vowels [a], [u] and [i] were obtained from 160 kindergarten children with a mean age of approximately 6.2 years. Subjects were grouped by sex and by the presence or absence of a voice disorder. Stop watch measurements of each subject's maximum phonations were compared with graphic level recorder measurements of those phonations . The results indicated that (1) the factor of sex had no significant effect on maximum phonation times; (2) the factor of voice group (non-voice-disordered/voice-disordered) did result in a significant effect (P less than 0.01) with the voice-disordered group achieving shorter phonations than the non-voice-disordered group; (3) the phonation times obtained from the two measurement procedures correlate significantly (P less than 0.05). Results also suggest that the vowel effect on maximum phonation time was significant (P less than 0.05) for both groups. The vowel [i] was phonated significantly longer than either [a] or [u] for males and females in both groups.

The aim of this study was to compare the effect of probiotic bacteria, prebiotics, phytobiotics and their combinations on performance and microbial activity in the digestive tract of growing pigs. The experiment was conducted over 28 d on 48 male pigs of about 12 kg body weight (BW), which were allocated to following treatments.: (1) Control Group (Con) without additive, (2) Group I, addition of a prebiotic (inulin), (3) Group Ph, a phytobiotic (herbal water extracts), (4) Group P, a probiotic composed of four strains of lactic acid bacteria, (5) Group PhP, phytobiotic and probiotic bacteria and (6) Group PhPI, a phytobiotic, probiotic bacteria and a prebiotic. Animal performance was recorded and at d 28 six pigs from each group were euthanised to collect digesta samples. In all groups except for Group I, diarrhoea incidents were observed. Groups Ph and P had significantly higher daily gains and final BW, and Group Ph utilised feed better than other groups. The pH of ileal digesta was significantly lower in Group PhPI. In the caecal digesta of Groups I, P and PhP, the pH level was lower than in the other groups but dry matter contents was significantly higher in Groups Con and I. The short-chain fatty acids and particular acid content differed significantly only in the colonic digesta. The yeast and mould numbers in caecal digesta was highest in Group Con. No treatment effects were observed for the number of lactic acid bacteria, coli group bacteria or Clostridium. However, the observed significantly higher number of total bacteria suggests that a multi-component eubiotic treatment changes the bacterial composition and distribution more effectively. Our findings indicated that all used additives changed the intestinal microflora, but the multi-component eubiotics were not beneficial as feed additives offered separately. Moreover, supplementation of phytobiotics and probiotic bacteria also improved the animal performance significantly.

The protective effect of L-carnitine was investigated against tilmicosin-induced cardiotoxic effects including blood creatine kinase (CK), CK-MB, total sialic acid as well as the alterations in glutathione and malondialdehyde concentrations in mice. Thirty-two Balb/C mice were divided into four groups including group 1 (control), group 2 (L-carnitine, s.c., 500 mg/kg for 5 days), group 3 (tilmicosin, s.c., single dose of 75 mg/kg) and group 4 (L-carnitine plus tilmicosin). Serum CK, CK-MB and malondialdehyde (MDA) levels were significantly (P < 0.05) higher in group 3 compared with those of other groups. Total sialic acid level in group 3 was found to be significantly (P < 0.05) higher than that in groups 1 and 2, as well. Contrary to these results, glutathione level in group 3 was found to be significantly (P < 0.05) lower than that in groups 1 and 2. In group 4, serum CK, CK-MB, MDA and total sialic acid levels were found to be significantly (P < 0.05) lower than those in group 3. These results suggest that tilmicosin is cardiotoxic in mice as evidenced by higher total sialic acid, CK and CK-MB. In addition, tilmicosin caused the decrease in glutathione and increase in MDA levels. However, administration of L-carnitine could ameliorate these adverse toxic effects of tilmicosin in mice.

Fatigue is the most common and highly disabling symptom of multiple sclerosis (MS) that has negative effects on employment, the process of socialization, compliance with the disease, and other factors effective on activities of daily living. The usage of complementary and alternative medicine methods in MS patients is higher than in the general population. However, there is no scientific evidence to support their effectiveness. Therefore, this study aimed to compare the effects of reflexology and relaxation on fatigue in women with MS. This study is a single-blinded randomized clinical trial that was done on 75 patients with MS who referred to the MS Clinic of Ayatollah Kashani Hospital (Isfahan, Iran). After simple non-random sampling, participants were randomly assigned by minimization method to three groups: Reflexology, relaxation, and control groups (25 patients in each group). In the experimental groups, the interventions foot reflexology and relaxation (Jacobson and Benson) were performed for 4 weeks, twice a week for 40 min in each session, and the control group received care and routine medical treatment as directed by a physician. Data were collected through a questionnaire and the fatigue severity scale before, immediately after, and 2 months after interventions from all three groups. Data analysis was performed by SPSS version 18 using descriptive and inferential statistical methods. Findings obtained from analysis of variance (ANOVA) showed that there was no significant difference in the mean fatigue severity scores in the pre-interventions between the three groups (P > 0.05), but there was significant difference immediately after and 2 months after interventions between the three groups (P < 0.05). Findings obtained from repeated measures (ANOVA) showed that there was significant difference in the mean fatigue severity scores during different times between the three groups (P < 0.05), while this difference was not significant in the control group (P > 0.05). Furthermore, least significant difference post-hoc test revealed that the mean scores of fatigue severity immediately after intervention was lower in the reflexology group than in the other two groups and were lower in the relaxation group than in the control group; 2 months after interventions, the mean scores of fatigue severity were lower in the reflexology group than in the other two groups, but there was no significant difference between the two groups of relaxation and control (P > 0.05). It seems that both interventions were effective in reducing fatigue, but the effects of reflexology on reducing fatigue were more than those of relaxation. Hence, as these two methods are effective and affordable techniques, they can be recommended.

Effects of human chorionic gonadotropin combined with clomiphene on serum E 2 , FSH, LH and PRL levels in patients with polycystic ovarian syndrome were analyzed. 90 patients with polycystic ovarian syndrome treated from January 2015 to March 2016 were randomly and evenly divided into control group and observation group. Patients in the control group were only treated with clomiphene. On the basis of the treatment in control group, human chorionic gonadotropin was added in the treatment of observation group. The changes of E 2 , FSH, LH, PRL levels were compared between two groups before and after the treatment. Clinical curative effects of patients in the two groups was evaluated. Adverse reactions during treatment in two groups were observed and recorded. The incidence of adverse reactions was calculated. Serum E 2 , FSH, LH and PRL levels in the two groups decreased significantly after treatment compared with that before treatment. The difference is statistical significant ( P  < 0.05). After the treatment, E 2 , FSH, LH and PRL levels in the observation group were lower than that in the control group and the difference is statistical significant ( P  < 0.05). Total effective rate was 64.44% in the control group and 93.33% in the observation group. There were statistically significant difference in clinical curative effects in the two groups ( P  < 0.05). Different degrees of adverse reactions were found in both groups during treatment, such as nausea, vomiting, anorexia, liver dysfunction. There were 2 cases of nausea, 2 cases of vomiting, 3 cases of anorexia and 1 case of liver dysfunction from the 45 patients in control group. The total incidence of adverse reactions was 17.78% (8/45). There were 1 case of nausea, 1 case of vomiting, 1 case of anorexia and no liver dysfunction from the 45 patients in observation group. The total incidence of adverse reactions was 6.67% (3/45). The total incidence of adverse reactions in the observation group was significantly higher than that in the control group and the difference was not statistically significant ( P  > 0.05). Combined use of human chorionic gonadotropin can significantly reduce serum E 2 , FSH, LH and PRL levels, improve clinical curative effects and reduce the incidence of adverse reactions. Human chorionic gonadotropin has high application value on the treatment of polycystic ovary syndrome.

The purpose of the current study was to examine the effect of Astaxanthin (Asx) supplementation on muscle enzymes as indirect markers of muscle damage, oxidative stress markers and antioxidant response in elite young soccer players. Thirty-two male elite soccer players were randomly assigned in a double-blind fashion to Asx and placebo (P) group. After the 90 days of supplementation, the athletes performed a 2 hour acute exercise bout. Blood samples were obtained before and after 90 days of supplementation and after the exercise at the end of observational period for analysis of thiobarbituric acid-reacting substances (TBARS), advanced oxidation protein products (AOPP), superoxide anion (O2•¯), total antioxidative status (TAS), sulphydril groups (SH), superoxide-dismutase (SOD), serum creatine kinase (CK) and aspartate aminotransferase (AST). TBARS and AOPP levels did not change throughout the study. Regular training significantly increased O2•¯ levels (main training effect, P<0.01). O2•¯ concentrations increased after the soccer exercise (main exercise effect, P<0.01), but these changes reached statistical significance only in the P group (exercise x supplementation effect, P<0.05). TAS levels decreased significantly post- exercise only in P group (P<0.01). Both Asx and P groups experienced increase in total SH groups content (by 21% and 9%, respectively) and supplementation effect was marginally significant (P=0.08). Basal SOD activity significantly decreased both in P and in Asx group by the end of the study (main training effect, P<0.01). All participants showed a significant decrease in basal CK and AST activities after 90 days (main training effect, P<0.01 and P<0.001, respectively). CK and AST activities in serum significantly increased as result of soccer exercise (main exercise effect, P<0.001 and P<0.01, respectively). Postexercise CK and AST levels were significantly lower in Asx group compared to P group (P<0.05) The results of the present study suggest that soccer training and soccer exercise are associated with excessive production of free radicals and oxidative stress, which might diminish antioxidant system efficiency. Supplementation with Asx could prevent exercise induced free radical production and depletion of non-enzymatic antioxidant defense in young soccer players.

This study examined variations in the main and buffering effects of ethnic and nonethnic social support on depressive symptoms associated with discrimination among five immigrant groups in Toronto. Data were taken from the Toronto Study of Settlement and Health, a cross-sectional survey of adult immigrants from five ethnic communities (Vietnamese, Ethiopian, Iranian, Korean, and Irish) in Toronto. A total of 900 surveys were collected through face-to-face interviews conducted between April and September 2001. Significant ethnic variations were observed in the effects of both ethnic and nonethnic social supports on discrimination-related depressive symptoms. Regarding the main effect, ethnic social support was significantly stronger for Iranian, Ethiopian, and Korean immigrants than for Irish immigrants. The benefits of nonethnic support were stronger for Iranian immigrants compared to the effect found in the Irish sample. With respect to stress-buffering or stress-moderating effects of social support, ethnic support was significant in all ethnic groups, except the Vietnamese group. Nonethnic support aggravated the negative impact of discrimination on depressive symptoms in the Irish group, but exerted a stress-buffering effect in the Iranian group. Overall, social supports received from fellow ethnic group members had significant main effects (suppressing depressive symptoms) and stress-buffering effects and were most pronounced in the minority ethnic immigrant groups of Ethiopians, Koreans, and Iranians. The effects were least evident among the Vietnamese and Irish. Evidence for the stress-suppressing and stress-buffering role of cross-ethnic group supports was unclear, and even inverted among Irish immigrants. Empirical evidence from the current study seems to support the sociocultural similarity hypothesis of social support.

To observe and compare the clinical curative effect of the plasma exchange (PE) and intravenous immunoglobulin (IVIg) for Guillian-Barre Syndrome (GBS). Overall, 64 adult patients with GBS for PE and IVIg treatment, respectively, and nerve function were observed pre-treatment and at 1 week/2 weeks after completion of treatment; the blood immunoglobulin, complement, fibrinogen (Fib) and monocyte percentage (MON%) were detected simultaneously. After PE treatment, nerve function defect appeared to improve better than the IVIg group and clinical effect was better than the IVIg group. Treatment effective rates of the two groups after 2 weeks, respectively, are 96 and 79%. PE and IVIg can significantly reduce the GBS patients' blood immunoglobulin IgG, IgA, IgM, C3 and C4, but these were significantly lower in the PE group than in the IVIg group. Fib and MON% were significantly lower in the PE group than in the IVIg group. Both PE and IVIg have a high response as therapy and are reasonable therapeutic options for GBS. However, PE treatment has a more significantly curative effect, as it can effectively improve symptoms and be helpful in the early rehabilitation of patients. © 2014 British Blood Transfusion Society.

The aim of this study was to investigate whether renal sympathetic denervation (RSD) is more effective on myocardial hypertrophy than the angiotensin-converting enzyme inhibitor (ACEI) perindopril in spontaneously hypertensive rats (SHRs). After bilateral renal denervation blood pressure (BP) was measured every 10 days. On day 50 the heart was (histo)pathologically examined. The ventricular weight to body weight ratios (VW/BW), myocardial diameter and collagen volume fraction (CVF) were calculated, and cardiac hypertrophy marker genes were analyzed by RT-PCR. At the baseline evaluation all groups had comparable BP. After treatment the BP of the RSD group was significantly reduced (p < 0.05). The BP of the RSD group was lower than that of the perindopril group on days 10, 20 and 30th (p < 0.05) but on day 50 systolic BP of the RSD group was significantly higher (p < 0.05) whereas there were no significant differences in diastolic BP. The VW/BW decreased in the RSD group, whereas the value did not change significantly in the perindopril group. The myocardial diameter of the left ventricular cardiomyocytes was also significantly lower in the RSD group and stayed the same in the perindopril group. Collagen volume fraction (CVF) in the RSD group was significantly lower than in the perindopril group (p < 0.05). Significant changes in the expression levels of NPPA, MYH7, and MYH6 (P < 0.05) were observed in the RD-SHR groups (p < 0.05). There was a significant difference in the expression level of MYH6 (p < 0.05) between the RSD group and the perindopril group but the expression levels of NPPA and MYH7 were not significantly different. In this study, RSD had a significant antihypertensive effect and inhibited hypertensive-induced cardiac hypertrophy in SHRs and showed advantages compared with ACEI in decreasing BP in the early stage and in inhibiting myocardial fibrosis.

Objective: Tailor-made notched music was applied to alleviate the symptoms of chronic idiopathic tinnitus and compared its effectiveness with other existing sound treatment of tinnitus. Methods: Subjects ( n =43; ears=75 )were recruited during June 2015 to October 2016 from the out-patients of our hospital. These patients had chronic (longer than 6months) and idiopathic tinnitus, with or without significant sensorineural hearing loss. In the prospective design, the patients were randomly divided into group A (treated with tailor-made notched music) and group B (treated with analogous sound masking), and received the treatment for 3 months. The tinnitus scale, tinnitus questionnaire and audiological findings were evaluated before treatment, and at one month and three months after treatment started. Results: After onemonth of treatment, the effective rate between the two groups was 40.9% and 42.9%, there was no significant difference between the two groups (χ(2)= 0.017, P =0.897). The average VAS for patients in group A showed more decrease in group A than in group B(VAS: 1.8 vs . 0.8, the percentage : 29.5% vs . 13.6%), but there was no significant difference between the two groups ( t =-1.450, P =0.155). After 3 months of treatment, the effective rates were 68.2% and 23.8%, respectively. There was significant difference between the two groups (χ(2)= 8.503, P =0.004). The difference of the VAS scores between the two groups was statistically significant ( t =-3.263, P =0.002), and the VAS score of group A was less.After 3 months of treatment, there was significant decreaseinthe average tinnitus loudness for patients in group A( t =5.569, P <0.01), and there was no significant changein group B( t =-0.953, P =0.374). There was also significant decreasein the scores of tinnitus handicap inventory (THI) ( F =7.334, P <0.05), loudness visual analog scale (VAS) ( F =20.48, P <0.001), and the proportion of patients with moderate to severe tinnitus(χ(2)=11.289, P <0.05) in the group A, and there was no significant change in group B( F =2.198, F =0.989, χ(2)=1.651; P =0.120, P =0.378, P =0.438>0.05). Conclusions: Our resultssuggest that long-term normalized listening to tailor-made notched music, can significantly reduce the perceived tinnitus loudness in varying degrees and improve the quality of life of patients. The effects and possible mechanism of this method were discussedin this paper.

The aim of the present study was to investigate the effect of the caspase-3 inhibitor z-DEVD-fmk on the apoptosis of the brain tissues of rats with acute cerebral infarction. Middle cerebral artery occlusion was used to establish a rat model of infarction, and the rats were randomly divided into a sham group (n=15), model group (n=15) and treatment group (n=15). z-DEVD-fmk (2.5 µg/kg) was injected into the intracranial artery of rats in the treatment group, while the same volume of phosphate-buffered saline solution was administered to the rats of the sham and model groups. After 48 h, all rats were sacrificed and their brain tissues were removed. The caspase-3 mRNA level, protein level and activity, brain cell apoptosis index and infarction scope of the three groups were analyzed. Neurological impairment was also assessed. At 48 h after model establishment, the caspase-3 mRNA and protein levels in the brain tissues of the model group were significantly higher than those of the sham group, and those in the treatment group were significantly lower than those in the model group (P<0.05); however, they remained significantly higher than those in the sham group. Caspase-3 activity in the model group was significantly higher than that in the sham group, and treatment with the caspase-3 inhibitor significantly reduced caspase-3 activity compared with that in the model group (P<0.05). The apoptosis index and infarction scope in the model and treatment groups were significantly increased compared with those in the sham group, and were significantly lower in the treatment group than in the model group (P<0.05). The neurological impairment of rats in the model and treatment groups was increased significantly compared with that in the sham group, and the treatment group exhibited a significantly lower level of neurological impairment than the model group (P<0.05). In conclusion, the caspase-3 inhibitor z-DEVD-fmk effectively inhibited apoptosis and delayed the necrosis of brain tissue cells in rats with acute cerebral infarction, and had certain protective effects on brain tissue.

Swedish Massage Therapy (SMT) is known for its therapeutic relaxation effects. Hypertension is associated with stress and elevated endothelial inflammatory markers. This randomized control trial measured the effects of whole body SMT (massage group) or resting (control group) an hour weekly for four weeks on hypertensive women. Blood pressure (BP) and heart rate (HR) were measured before and after each intervention and endothelial inflammatory markers: vascular endothelial adhesion molecules 1 (VCAM-1) and intracellular adhesion molecules 1 (ICAM-1) were measured at baseline and after the last intervention. Massage group (n=8) showed significant systolic BP (SBP) reduction of 12 mmHg (P=0.01) and diastolic BP (DBP) reduction of 5 mmHg (P=0.01) after four sessions with no significant difference between groups. Reductions in HR were also seen in massage group after sessions 1, 3, and 4 with significant difference between groups. VCAM-1 showed significant reduction after four sessions: the massage group showed reduction of 998.05 ng/mL (P=0.03) and the control group of 375.70 ng/mL (P=0.01) with no significant differences between groups. There were no changes in ICAM-1. In conclusion, SMT or resting an hour weekly has effects on reducing BP, HR, and VCAM-1 in hypertensive women.

To Compare clinical therapeutic effect of improved thunder-fire miraculous needle and moxibustion on vertigo. One hundred and seventeen cases conformed with the TCM criteria of vertigo were randomly divided into an observation group (n=66) and a control group (n=51). The observation group were treated with improved thunder-fire miraculous needle and the control group with pressing and moxibustion at Baihui (GV 20). After treatment of one therapeutic course, the therapeutic effect was assessed by vertigo symptom rating scores. The total effective rate was 86.4% in the observation group and 66.7% in the control group, with a significant difference between the two groups (P<0.05). The improved thunder-fire miraculous needle can significantly relieve and eliminate symptoms of vertigo, with no adverse effect.

The aim of this study was to evaluate and compare audio and audiovisual distraction aids in management of anxious pediatric dental patients of different age groups and to study children's response to sequential dental visits with the use of distraction aids. This study was conducted on two age groups, that is, 4-6 years and 6-8 years with 30 patients in each age group on their first dental visit. The children of both the age groups were divided into 3 subgroups, the control group, audio distraction group, audiovisual distraction group with 10 patients in each subgroup. Each child in all the subgroups had gone through three dental visits. Child anxiety level at each visit was assessed by using a combination of anxiety measuring parameters. The data collected was tabulated and subjected to statistical analysis. Tukey honest significant difference post-hoc test at 0.05% level of significance revealed audiovisual group showed statistically highly significant difference from audio and control group, whereas audio group showed the statistically significant difference from the control group. Audiovisual distraction was found to be a more effective mode of distraction in the management of anxious children in both the age groups when compared to audio distraction. In both the age groups, a significant effect of the visit type was also observed.

Old/New Effect of Digital Memory Retrieval in Chinese Dyscalculia.

PubMed

Wang, Enguo; Du, Chenguang; Ma, Yujun

This study reports the neurophysiological and behavioral correlates of digital memory retrieval features in Chinese individuals with and without dyscalculia. A total of 18 children with dyscalculia (ages 11.5-13.5) and 18 controls were tested, and their event-related potentials were digitally recorded simultaneously with behavior measurement. Behavioral data showed that the dyscalculia group had lower hit rates and higher false rates than the control group. The electroencephalography results showed that both groups had a significant old/new effect and that this effect was greater in the control group. In the 300 to 400 ms processing stages, both groups showed significant differences in digital memory retrieval in the frontal regions. In the 400 to 500 and 500 to 600 ms epochs, the old/new effect in the control group was significantly greater than it was in the dyscalculia group at the frontal, central, and parietal regions. In the 600 to 700 ms processing stages, both groups showed significant differences in digital memory retrieval in the frontal, central, parietal, and occipital regions. These results suggest that individuals with dyscalculia exhibit impaired digital memory retrieval. Extraction failure may be an important cause of calculation difficulties.

Effects of balneotherapy on Primary Fibromyalgia Syndrome (FMS) have been studied well, except for its effect on the respiratory symptoms of FMS. In this study we allocated 56 patients with FMS into three groups who matched according to age, gender and duration of illness. All three groups received the same three physical therapy modalities (PTM): transcutaneous electrical nerve stimulation (TENS), ultrasound (US) and infrared (IR). The first group received PTM plus balneotherapy (PTM+BT), the second group received PTM alone (PTM), whilst the third group received PTM plus hydrotherapy (PTM+HT). All groups were treated for three weeks and in the same season. All patients were assessed at four time points: (a) at baseline, (b) on the 7th day of therapy, (c) at the end of therapy (after 3 weeks) and (d) at 6 months after the end of therapy. The effectiveness of treatments in all groups were evaluated in three main categories (pain, depressive and respiratory symptoms). Tender point count, total algometric measurements and pain with visual analog scale for pain; Beck Depression Inventory (BDI) and Hamilton Depression Rating Scale (HDRS) for depression; dyspnea scale, and spirometric measurements for respiratory symptoms; plus quality of life with visual analog scale as a general measurement of effectiveness were taken at all four assessment time points.Both at the end of therapy and at the 6 months follow up significant improvements in dyspnea scale, and spirometric measurements, as well as in other measured parameters were observed in group PTM+BT. All groups achieved significant improvements in BDI and HDRS but scores of PTM and PTM+HT groups had overturned at 6 months follow up. Except second group which receieved PTM alone, pain evaluation assessments were improved at 6 month follow up in PTM+HT and PTM+BT groups. But PTM+BT group had more significant improvements at the end of therapy. PTM group had no significant change for dyspnea scale and spirometric measurements. PTM combined BT and HT groups achieved significant improvements at the end of therapies for dyspnea scale and spirometric measurements, but only PTM +BT group had significant improvements for dyspnea scale and spirometric measurements at six month follow up. The group of PTM+BT was significantly better than other groups. Our results suggest that supplementation of PTM with balneotherapy is effective on the respiratory and other symptoms of FMS and these effects were better than other protocols at 6 month follow up.

To evaluate the effectiveness and safety of triptorelin in the treatment of uterine leiomyoma. A multi-center, prospective, randomly controlled clinical trial was carried out from Dec. 2002 to Mar. 2004 in three university hospitals. A total of 125 qualified patients with uterine leiomyoma were randomly divided into either triptorelin group (63 cases) treated with 3.75 mg triptorelin injected intramuscularly or leuprorelin group (62 cases) treated with 3.75 mg leuprorelin injected subcutaneously. Both drugs were injected every 28 days for a total of 3 months. All 125 patients finished the trial. The uterine volumes were similar before treatment between the triptorelin group and the leuprorelin group and were decreased significantly after drug therapy (P < 0.01) in both groups, with a median decrease rate of 51% and 49%, respectively, without significant difference between two groups (P > 0.05). The volumes of the largest leiomyoma decreased significantly after drug therapy (P < 0.01) in both groups, with a median decrease rate of 50% and 48% in the triptorelin and leuprorelin groups, respectively, without significant difference between them (P > 0.05). Patients with serum level of 17beta-estradiol < 183 pmol/L accounted for 94% in both groups. The hemoglobin and serum ferrum levels were both significantly increased in the two groups after treatment (P < 0.05). The amenorrhea rates after 3 months of treatment were 97% in the triptorelin group and 95% in the leuprorelin group (P > 0.05). Dysmenorrhea, noncyclic pelvic pain and pressure-like symptoms were relieved quickly and remarkably in both groups after treatment. The rates of adverse event occurred in 71% of patients in both groups. The main side effects included flare-up effects and hypoestrogenic symptoms. Nine patients in the triptorelin group and 6 in the leuprorelin group received add-back therapy with tibolone 1.25-2.50 mg/d because of remarkable climacteric-like symptoms. Treatment of uterine leiomyoma with triptorelin for 3 months is both effective and safe in Chinese women.

To compare remineralization potential of topical fluoride varnishes with added calcium phosphate-based delivery systems on artificial enamel caries. Human enamel specimens (n = 60) were randomly divided into six groups: Group 0: Control (no varnish), Group 1: Duraphat ® , Group 2: MI Varnish ™ , Group 3: Embrace ™ Varnish, Group 4: Enamel Pro ® Varnish, and Group 5: Clinpro ™ White Varnish. Specimens were immersed in demineralizing solution for 96 h to create artificial caries lesion. Each specimen was then immersed in artificial saliva for 6 h after fluoride varnish application and pH cycling was performed for 8 days. Specimens were evaluated using Knoop surface microhardness (KHN) and transverse microradiography (TMR). One-way anova test was performed to examine the effect of fluoride varnishes on change in percentage of surface hardness recovery (%SHR), change in lesion depth (ΔLD), and change in mineral loss (ΔΔZ) with the significance limit set at 5%. %SHR of enamel following treatment with Group 1 was significantly higher than Group 3 and Group 4. Conversely, ΔLD and ΔΔZ of Group 1 were significantly higher than Group 2, Group 3, and Group 4. No significant differences in %SHR, ΔLD, and ΔΔZ were found between Group 1 and Group 5. Duraphat ® alone achieves significant remineralization of enamel carious lesions. Clinpro ™ White Varnish had similar enamel remineralization effect as Duraphat ® . © 2016 BSPD, IAPD and John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The aim of this study was to compare the effect of a percutaneous radiofrequency heat lesion at the medial branch of the primary dorsal ramus with a sham procedure, for the treatment of lumbar facet joint pain. A randomised sham-controlled double blind multicentre trial was carried out at the multidisciplinary pain centres of two hospitals. A total of 60 patients aged > 18 years with a history and physical examination suggestive of facet joint pain and a decrease of ≥ 2 on a numerical rating scale (NRS 0 to 10) after a diagnostic facet joint test block were included. In the treatment group, a percutaneous radiofrequency heat lesion (80 o C during 60 seconds per level) was applied to the medial branch of the primary dorsal ramus. In the sham group, the same procedure was undertaken without for the radiofrequency lesion. Both groups also received a graded activity physiotherapy programme. The primary outcome measure was decrease in pain. A secondary outcome measure was the Global Perceived Effect scale (GPE). There was a statistically significant effect on the level of pain in the factor Period (T0-T1). However, there was no statistically significant difference with the passage of time between the groups (Group × Period) or in the factor Group. In the crossover group, 11 of 19 patients had a decrease in NRS of ≥ 2 at one month crossover (p = 0.65). There was no statistically significant difference in satisfaction with the passage of time between the groups (Group × Period). The independent factors Group and Period also showed no statistically significant difference. There was no statistically significant Group × Period effect for recovery, neither an effect of Group or of Period. The null hypothesis of no difference in the decrease in pain and in GPE between the treatment and sham groups cannot be rejected. Post hoc analysis revealed that the age of the patients and the severity of the initial pain significantly predicted a positive outcome.

To investigate the neuroprotective effect of leptin by observing its effect on spatial memory of rats with white matter damage in developing brain. A total of 80 neonatal rats were randomly divided into 3 groups: sham-operation (n=27), model (n=27) and leptin intervention (n=27). The rats in the model and leptin intervention groups were used to prepare a model of white matter damage in developing brain, and the rats in the leptin intervention group were given leptin (100 μg/kg) diluted with normal saline immediately after modelling for 4 consecutive days. The survival rate of the rats was observed and the change in body weight was monitored. When the rats reached the age of 21 days, the Morris water maze test was used to evaluate spatial memory. There was no significant difference in the survival rate of rats between the three groups (P>0.05). Within 10 days after birth, the leptin intervention group had similar body weight as the sham-operation group and significantly lower body weight than the model group (P<0.05); more than 10 days after birth, the leptin intervention group had rapid growth with higher body weight than the model and sham-operation groups (P>0.05). The results of place navigation showed that from the second day of experiment, there was a significant difference in the latency period between the three groups (P<0.05); from the fourth day of experiment, the leptin intervention group had a similar latency period as the sham-operation and a significantly shorter latency period than the model group (P<0.05). The results of space search experiment showed that compared with the sham-operation group, the model group had a significant reduction in the number of platform crossings and a significantly longer latency period (P<0.05); compared with the model group, the leptin intervention group had a significantly increased number of platform crossings and a significantly shortened latency period (P<0.05), while there was no significant difference between the leptin intervention and sham-operation groups. Leptin can alleviate spatial memory impairment of rats with white matter damage in developing brain. It thus exerts a neuroprotective effect, and is worthy of further research.

This study's aim was to investigate the effect of melatonin in terms of mitigating the effects of smoking on the laryngeal mucosa of rats exposed to environmental tobacco smoke. Rats were divided into four groups: Melatonin + Smoking group exposed to smoke with melatonin; Smoking group exposed to smoke without melatonin; Saline group not exposed to smoke without melatonin; Melatonin group not exposed to smoke with melatonin. CuZn-superoxide dismutase (CuZn-SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) activities were evaluated in plasma and tissues. Tissues were also examined the changes of squamous hyperplasia, keratosis, parakeratosis and epithelial hyperplasia by light microscope and the ultrastructural changes by electron microscope. Tissue SOD, CAT and GSH-Px activities were significantly higher in Saline and Melatonin groups than Melatonin + Smoking and Smoking groups. Plasma CuZn-SOD and CAT activities were significantly higher in Saline and Melatonin groups than Smoking group. Plasma GSH-Px showed no significant difference. The rate of epithelial hyperplasia was significantly higher in Smoking group than the other groups. The rate of parakeratosis was significantly higher in Smoking group than the other groups. The epithelial cells in Melatonin + Smoking group displayed, normal cell structure similar to those in Saline group under electron microscope. The study shows that smoking induces substantial pathological changes in the laryngeal mucosa and melatonin may have some beneficial effects in partially reversing smoking-induced laryngeal injury by inducing the expression of antioxidants; biochemical and histological outcomes also support these findings due to preventing tissue damage in laryngeal mucosa exposed to smoke. © 2015 John Wiley & Sons Ltd.

During preoperative radiotherapy, effective doses of ionizing radiation occasionally cause wound complications after subsequent surgery. This study was designed to determine the effects of intraperitoneally or orally administered N-acetylcysteine (NAC) on anastomotic healing of irradiated rats. Forty Wistar albino rats were randomized into four groups containing 10 rats each. A 3 cm long surgical full-thickness midline laparotomy was performed to all groups (Groups 1-4). Group 1 was designed as a control group without radiation therapy and NAC treatment. Groups 2, 3 and 4 received a single abdominal dose of 10 Gy irradiation before laparotomy and groups 3 and 4 received oral and intraperitoneal NAC, respectively. Group comparisons demonstrated that breaking strength was significantly higher in NAC treated rats. A statistically significant difference was determined in terms of superoxide dismutase (SOD), malondealdehyde (MDA) and glutation (GSH) values between groups (p<0.001). Nevertheless, advanced oxidation protein products (AOPP) levels were found to be similar between groups (p=0.163). Serum GSH and SOD levels were significantly higher in groups 3 and 4 when compared to group 2 (p < 0.05). Similarly, there was a significant increase in serum MDA concentration, predicting lipid peroxidation, in group 2 when compared to groups 1, 3 and 4 (p < 0.05). There was not a significant difference between Groups 3 and 4 regarding GSH, MDA, SOD, and AOPP levels. Histopathological analysis revealed that NAC administration, either orally or intraperitoneally, leads to a better incisional healing in terms of inflammation, granulation, collagen deposition, reepithelization and neovascularization. The present study supports the hypothesis that NAC administration alleviates the negative effects of radiotherapy on incisional wound healing by means of reducing oxidative stress markers and improving histologic parameters independent of the route of administration.

To evaluate the effect of letrozole in combination with cabergoline and letrozole alone on regression of symptomatic uterine myomas in women of reproductive age. Randomized controlled clinical trial. University hospital. Ninety-one women of reproductive age were enrolled in the study and 88 women were eligible. Eight participants were excluded from the study. Eighty women of reproductive age with symptomatic myomas >4cm were evaluated in two groups. Participants in Group 1 received 2.5mg letrozole once daily and cabergoline 0.5mg/week from the first day of the menstrual cycle for 12 weeks, and participants in Group 2 received letrozole alone. Changes in uterine size and volume; myoma size, volume and number; and side effects of treatment. Overall, 76 patients completed the study. Compared with baseline values, mean uterine volume was reduced significantly in both groups (p=0.01), and there was no significant difference between groups (p=0.99). The mean number of dominant myomas was reduced significantly in both groups (p=0.03), with no significant difference between groups (p=0.6). The mean volume of myomas was reduced significantly in both groups (p=0.01), with no significant difference between groups (p=0.45). Although a significant decrease in number and volume of myomas was documented in each group (p<0.05), the intergroup analyses did not reveal significant differences between the two groups in terms of the change in number (p=0.28) and volume (p=0.96) of myomas. Headache was significantly more common in the letrozole+cabergoline group (nine vs two cases, p=0.02), but the two groups were comparable for the remaining minor side effects. This study showed that 12 weeks of treatment with letrozole with and without cabergoline improved the size and volume of the uterus and myomas, led to symptom improvement, and could be used for short-term treatment prior to surgery or fertility programmes.

To delineate the effect of chronic electromagnetic field (EMF) exposure from radar on plasma melatonin and serotonin levels in occupationally exposed military personnel. A total of 166 male military personnel participated in the study out of which only 155 joined for blood draw. They were divided into three sets: Control group (n = 68), exposure group I (n = 40) exposed to 8-12 GHz and exposure group II (n = 58) working with radar at 12.5-18 GHz frequency. The three groups were further split into two groups according to their years of service (up to 10 years and > 10 years) in order to investigate the effect of years of exposure from radar. Melatonin and serotonin levels were estimated by enzyme immunoassay in fasting blood samples collected from 06:00-07:00 h. EMF measurements were recorded at different locations using Satimo EME Guard 'Personal Exposure Meter' and Narda 'Broad Band Field Meter'. The group I exposed population registered a minor though not significant decrease in plasma melatonin concentration while the other group II exposed population registered statistically significant decline in melatonin concentration when compared with controls. Highly significant increase in plasma serotonin levels was found in exposure group II when compared to control whereas marginal non-significant rise was also registered in exposure group I in comparison to control. Exposure in terms of length of service up to 10 years did not produce any significant effect in the indoleamine levels in both the exposure groups when they were compared with their respective control groups. Whereas, length of service greater than 10 years was observed to decrease and increase respectively the melatonin and serotonin concentration significantly in exposure group II but not in exposure group I. However, correlation test did not yield any significant association between years of service and melatonin or serotonin levels respectively in both the exposure sets I and II. No significant association was observed between melatonin and serotonin levels as well. The study showed the EMF ability to influence plasma melatonin and serotonin concentration in radar workers, significantly in 12.5-18 GHz range with service period greater than 10 years.

Purpose. To evaluate the treatment effect and side effect of Shenqi Fuzheng Injection (SFI) on alleviating transient worsening of myasthenia gravis (MG) symptoms caused by high-dose steroids pulse therapy. Methods. Sixty-six consecutive patients with MG were randomly divided into two groups: the treatment group treated with SFI and methylprednisolone pulse therapy (MPT) and the control group treated with MPT alone. The severity of MG before, during, and after MPT and the duration of transient worsening (TW) were evaluated and compared with the clinical absolute scoring (AS) and relative scoring (RS) system. Results. Twenty-nine patients experienced TW in each group. At TW, the AS was significantly increased (P < 0.000) in both groups compared with baseline data, with the AS increase in the treatment group (16.8 ± 2) significantly smaller (P < 0.05) than in the control group (24.9 ± 2.5). At the end of the treatment course, the AS for the treatment group was significantly decreased (7.5 ± 0.9) compared with at TW, although no significant difference compared with the control (9.7 ± 1.1). The TW lasted 1–6 days (mean 3.7) for the treatment group, significantly shorter (P < 0.05) than 2–12 days (mean 7.8) for the control. The RS for the treatment group at the end of treatment was 43.8%–100% (mean 76.8% ± 2.6%), significantly better than the control group: 33.3%–100% (mean 67.2 ± 3.6%). Slight side effects (18.75%) included maldigestion and rash in the treatment group. Conclusion. SFI has a better treatment effect and few side effects and can alleviate the severity and shorten the duration of the transient worsening of MG during steroids pulse therapy. PMID:24348721

To evaluate the effects of Urtica dioica on hepatic ischemia-reperfusion injury. Thirty adult male Wistar albino rats were divided into three groups: sham group (group 1), control group (group 2), and Urtica dioica group (group 3). All the rats were exposed to hepatic ischemia for 60 min, followed by 60 min of reperfusion. In group 2, a total of 2 ml/kg 0.9% saline solution was given intraperitoneally. In group 3, a total of 2 ml/kg Urtica dioica was given intraperitoneally. At the end of the procedure, liver tissue and blood samples were taken from all rats. Serum aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, ceruloplasmin, catalase, paraoxonase, arylesterase, and lipid hydroperoxide levels were measured. Liver tissue histopathologies were also evaluated by light microscopy. Serum aspartate aminotransferase, alanine aminotransferase and lactate dehydrogenase levels were significantly higher in group 2 than in group 1, and significantly lower in group 3 than in group 2. Also, group 2 had higher serum lipid hydroperoxides and ceruloplasmin levels but lower catalase, paraoxonase, and arylesterase levels than group 1. In group 3, serum lipid hydroperoxides and ceruloplasmin levels were significantly lower, and catalase, paraoxonase, and arylesterase levels were higher than those in group 2. Histopathological examination showed that liver tissue damage was significantly decreased in group 3 compared with group 2. Urtica dioica has a protective effect on the liver in hepatic ischemia-reperfusion-injured rats.

There are no studies that looked into the bubble eliminating efficacy of polyethylene glycol with ascorbic acid (PEGA), which has been one of the shortcomings of polyethylene glycol (PEG). In this study, we compared newly introduced PEGA regimen by adding either simethicone or 1 L of water. A prospective randomized controlled study was carried out at Dongguk Universtiy Gyeongju Hospital from July 2014 to September 2014. A total of 90 patients were randomly assigned to 3 groups; PEGA group (n=30) which served as control, simethicone addition group (n=30) to which simethicone 400 mg was additionally prescribed, and water addition group (n=30) to whom additional 1 L of water was given. Cleansing effectiveness, gas elimination efficacy, side effects, and patient satisfaction were compared between the groups. PEGA group demonstrated the highest cleansing effectiveness, but there was no statistically significant difference among the groups. Simethicone addition group showed significantly lesser amount of bubbles than the other groups (2.57±2.05 vs. 1.10±1.83 vs. 2.60±2.84, p=0.017). The rates of side effects in each group were 20.00% vs. 16.77% vs. 53.33%. Water addition group had significantly more side effects than the PEGA group and the simethicone addition group (p=0.003). The patient satisfaction score of each group was 3.37±0.85 vs. 3.73±0.74 vs. 3.20±0.66 with simethicone addition group showing significantly higher satisfaction than water addition group (p=0.020). PEGA bowel preparation agent showed satisfactory bowel cleansing despite the decrease in dosage, and addition of simethicone resulted in better bubble elimination.

Causes of placebo effects in antidepressant trials have been inferred from observational studies and meta-analyses, but their mechanisms have not been directly established. The goal of this study was to examine in a prospective, randomized controlled trial whether patient expectancy mediates placebo effects in antidepressant studies. Adult outpatients with major depressive disorder were randomly assigned to open or placebo-controlled citalopram treatment. Following measurement of pre- and postrandomization expectancy, participants were treated with citalopram or placebo for 8 weeks. Independent samples t tests determined whether patient expectancy differed between the open and placebo-controlled groups, and mixed-effects models assessed group effects on Hamilton Depression Rating Scale (HAM-D) scores over time while controlling for treatment assignment. Finally, mediation analyses tested whether between-group differences in patient expectancy mediated the group effect on HAM-D scores. Postrandomization expectancy scores were significantly higher in the open group (mean=12.1 [SD=2.1]) compared with the placebo-controlled group (mean=11.0 [SD=2.0]). Mixed-effects modeling revealed a significant week-by-group interaction, indicating that HAM-D scores for citalopram-treated participants declined at a faster rate in the open group compared with the placebo-controlled group. Patient expectations postrandomization partially mediated group effects on week 8 HAM-D. Patient expectancy is a significant mediator of placebo effects in antidepressant trials. Expectancy-related interventions should be investigated as a means of controlling placebo responses in antidepressant clinical trials and improving patient outcome in clinical treatment.

To explore the personality-adjusting effect of electro-acupuncture treatment for depression and compared this treatment with paroxetine treatment. A non-blinded, randomized controlled trial was adopted. Sixty depressed patients, who met trial criteria, were randomly assigned to the treatment and the control groups. In the treatment group, electro-acupuncture treatment was used, and paroxetine treatment was used in the control group. During the 24-week study period, 12 patients dropped out and 48 patients completed the study. The Minnesota Multiple Personality Inventory (MMPI) was adopted as the evaluation tool. At the same time, the Self-rating Depression Scale (SDS), Self-rating Anxiety Scale (SAS) and Montgomery-Asberg Depression Rating Scale (MADRS) were used to evaluate the psychological state. Evaluations were done before and after treatment. After treatment, patients' psychological state improved significantly in both groups (P<0.01). For the treatment group, within-group comparison between baseline and after 24 weeks of treatment showed that severity of depression had significantly decreased (P<0.01). MADRS and SDS scores decreased significantly (P<0.05) and MMPI subscale scores for hypochondriasis, depression, psychopathic deviate, psychasthenia, social introversion and fake decreased significantly (P<0.05). For the control group, severity of depression also decreased significantly. MADRS and SDS scores decreased significantly (P<0.05); and MMPI subscale scores for hypochondriasis, depression, hysteria, paranoia, and psychasthenia decreased significantly (P<0.05). Between-group comparison demonstrated that for the MMPI subscales paranoia and social introversion, the decrease of score was greater in the treatment group than in the control group (P<0.05). However, there were no other significant differences between the control group and the treatment group. Electro-acupuncture is effective for treating depression and affects personality traits.

Pain is one of the most common side effects of transcatheter arterial chemoembolization (TACE) treatment. This study aimed to assess the analgesic effect of parecoxib sodium for postoperative pain control in patients with inoperable hepatocellular carcinoma (HCC) undergoing TACE. This randomized placebo-controlled prospective clinical study was conducted at a single cancer centre. Patients were randomly assigned to receive parecoxib sodium (experimental group; n = 60) or 0.9 % sodium chloride (control group; n = 60) 1 h before TACE and once every 12 h for 2 days after TACE. Pain level, morphine consumption, adverse events, and quality of life were evaluated and compared between the two groups. Pain scores, percentage distribution of pain categories, and morphine consumption were significantly lower in the experimental group than in the control group (P < 0.05). Fever score comparisons revealed significantly better body temperature balance in the experimental group than in the control group (P = 0.024). Quality-of-life scores in the experimental group were significantly better than those in the control group (P < 0.05). Our results demonstrate that the perioperative administration of parecoxib significantly improved its effectiveness in the control of postoperative pain after TACE. • Perioperative administration of parecoxib is effective for control of pain after TACE. • COX-2 inhibitors provide effective and safe pain control. • Parecoxib helps improve quality-of-life after TACE for patients with inoperable hepatocellular carcinoma.

A community-based, randomized trial was designed to compare the effect of nutrition education and/or iron supplementation (weekly) on iron status of children in an urban slum in Delhi. Four hundred and fifty one children, 9-36 months of age and their caretakers (mothers), assigned to one of the following groups were included in the cohort. Group 1, nutrition education. Group 2, supplementation (with 20 mg elemental iron). Group 3, nutrition education with supplementation (with 20 mg elemental iron) and Group 4, control given placebo. The intervention program was of four months duration, with a treatment phase of 8 wk followed by 8 wk of no treatment. Post intervention, at 8 wk and at 16 wk, the hemoglobin change in the nutrition education, supplementation, nutrition education with supplementation and control groups was 2.9, 1.9, 3.8 and -5.9%, respectively and 2.1, -1.9, 0 and -9.3%, respectively (as compared to initial values). There was no significant effect of any of the intervention at 8 weeks. At 16 wk, there was significant positive effect of nutrition education group (p less than 0.05). The percent change in serum ferritin value at 16 wk in the nutrition education, supplementation, nutrition education with supplementation and control groups was 5.7, -2.3, -3.4 and -40%, respectively. Serum ferritin values were significantly higher for the nutrition education group (p < 0.001) as compared to the control. At 16 wk, the nutrition education group mothers showed significantly higher nutrition knowledge and the dietary iron intake of children was significantly higher than their control group counterparts (p < 0.0001). The study suggests that nutrition education did have a positive effect on the iron status possibly by improving the dietary iron intake.

Chronic exposure to n-hexane can lead to peripheral neuropathy that no effective treatment regimen could be applied presently. This study investigated whether myelin protein zero (P0) protein and its antibody could be used to distinguish n-hexane intoxication and protect workers from peripheral neuropathy. We compared P0 protein and its antibody among three levels of n-hexane-exposed groups, which included 18 patients with n-hexane-induced peripheral neuropathy as case group, 120 n-hexane-exposed workers as n-hexaneexposed control group, and 147 non-hexane-exposed participants used as control group. ELISA method was applied to detect P0 protein and its antibody. P0 protein in serum was significantly higher in the case group and n-hexane-exposed control group in comparison with the control group (P < 0.01). Compared with the n-hexane-exposed control group, the case group also had significant increase of P0 protein (P < 0.01). After 6 months therapy, P0 protein was observed to decrease significantly in the case group (P < 0.01). The P0 antibody in serum was significantly higher in the n-hexane-exposed control group than in the control group (P < 0.01), but not significantly different between cases and controls. P0 antibodies in serum may be a short-term effect biomarker for n-hexane exposure. P0 protein in serum may be an early effective biomarker for peripheral nerve neuropathy and its biological limit value needs investigation in the future study.

Purpose: To evaluate the effect of oral calcium dobesilate (Doxium) on macular thickness in clinically significant macular edema (CSME). Methods: Overall, 71 eyes of 40 patients with non-proliferative diabetic retinopathy and clinically significant macular edema were included. All patients were received laser treatment for macular edema. Coherence optical tomography was used to determine the retinal thickness. Patients were randomized into two groups: group A received three Doxium capsule daily and group B received three placebo capsule daily for six months. Results: The mean macular thickness before and after treatment in the group A was 340 and 257 micrometers respectively (24.5% reduced), and in the group B was 336 micrometers and 263 micrometers respectively (21.5% reduced). Macular thickness significantly decreased after treatment in both groups and the reduction in group A is higher but the difference of reduction between the two groups was not statistically significant (P>0.05). Conclusion: In respect to the effect of adding oral Doxium to Laser Photocoagulation on the macular thickness in patients with diabetic macular edema, this study showed no statistically significant difference between Doxium and placebo.

Periodontal regeneration using EDTA or PDGF showed promising results, but the effect of combined application was still unclear. This study aimed to verify the effect of EDTA and/or PDGF application on root adhesion and proliferation of PDL fibroblast cells. Eighty specimens were prepared from forty periodontitis teeth and made five groups: (1) diseased (untreated), (2) SRP (scaling root planing), (3) EDTA (24%), (4) PDGF (25 ng/ml) and (5) Combined application of EDTA and PDGF. Periodontal ligament cells were cultured on the above conditioned dentin plate, and SEM examination was preformed and cells were counted within a representative standard area for both cell morphology and density. All groups including untreated showed significantly increase of adhered cells from baseline to 7 days. Among them, rate of increase was much higher in EDTA, PDGF, and combined groups. ANOVA test indicated that the number of cells in PDGF and combined groups was significantly higher than diseased group at 1 day. On day 7, PDGF and combined groups showed significantly higher number of adhesion cells than that found in the diseased, SRP and EDTA groups. Thus, root conditioning with EDTA enhanced cell adhesion more than SRP alone. There was no significant difference of cell number between PDGF and combined group. Combined application of EDTA and PDGF increased significantly PDL cell adhesion than EDTA alone. PDGF alone, however, also showed comparable effect to combined application at all periods. Thus, synergistic effect between PDGF and EDTA was not observed.

To determine whether the effects of a patient-centered cultural competence curriculum could be sustained for one year. In 2006, 57 fifth-year medical students at National Taiwan University were randomly assigned either to a group that received training in patient-centered cross-cultural communication skills or one that received no training. Students' scores on objective structured clinical exams (OSCEs) were compared in the realms of exploring (1) patient perspectives and (2) social factors related to illness, immediately after training (OSCE1) and one year after training (OSCE2). Regarding students' exploration of patient perspectives, the intervention group scored significantly higher than the control group at OSCE1, but there was a significant decrease from OSCE1 to OSCE2 in the intervention group and no significant difference between the intervention and control group at OSCE2. Regarding students' exploration of social factors related to illness, the intervention group scored significantly higher than the control group at OSCE1, with a nonsignificant decrease from OSCE1 to OSCE2 in the two groups, such that the intervention group again scored higher than the control group in OSCE2. The effect of a patient-centered cultural competence training curriculum on students' exploration of social factors related to illness was sustained to a significant degree after one year, whereas the effects on students' exploration of patient perspectives were not. Further research is needed to determine the extent to which additional training can prevent the loss of student skills.

To observe the promoting effects of blood-activating and stasis-removing Chinese drugs combined with vascular endothelial growth factor (VEGF) gene transfer on angiogenesis in ischemic necrosis of the femoral head. Forty Japanese giant-ear rabbits were randomly divided into a control group, a model group, a Chinese drug group, a gene group, and a combined group. After 8 weeks of treatment, the rate of VEGF positive cell expression in the synovium of the femoral head was measured using the immunohistochemical method, and the number of blood vessels in the femoral head was measured by digital subtraction angiography. The rate of VEGF positive cell expression in the model group was significantly lower than that in the Chinese drug group (P < 0.05) and very significantly lower than those in other groups (P < 0.01); but in the combined group it was significantly higher than in the Chinese drug group (P < 0.05). The differences in the number of blood vessels in area A between the model group and other groups were not statistically significant. However, in area B, the number of blood vessels significantly increased in the control group, the gene group and the combined group as compared with the model group (P < 0.05), and in the combined group the number of blood vessels was significantly more than in the gene group (P < 0.05); but in the Chinese drug group it was not significantly different than the model group (P > 0.05). Either the blood-activating and stasis-removing Chinese drugs or VEGF gene transfer can promote the angiogenesis and building of collateral circulation for femoral head ischemic necrosis, and the combined therapy with Chinese drugs or VEGF gene transfer may show a better therapeutic effect. The present study provides an experimental basis for clinical application of the combined therapy with the blood-activating and stasis-removing Chinese drugs and VEGF gene transfer.

This single-blind randomised controlled trial explored the differential effects of two different foot reflexology techniques with a period of rest on oedema-relieving effects and symptom relief in healthy pregnant women with foot oedema. Fifty-five women in the third trimester were randomly assigned to one of the three groups: a period of rest, 'relaxing' reflexology techniques or a specific 'lymphatic' reflexology technique for 15 min with pre- and post-therapy ankle and foot circumference measurements and participant questionnaire. There was no statistically significant difference in the circumference measurements between the three groups; however, the lymphatic technique reflexology group mean circumference measurements were all decreased. A significant reduction in the women's symptom mean measurements in all groups (p<0.0001) was apparent. A 'perceived wellbeing' score revealed the lymphatic technique group (p<0.0001) significantly increased their wellbeing the most, followed closely by relaxing techniques (p<0.001) and then the control rest group (p<0.03). Lymphatic reflexology techniques, relaxing reflexology techniques and a period of rest had a non-significant oedema-relieving effect. From the women's viewpoint, lymphatic reflexology was the preferred therapy with significant increase in symptom relief.

Depression and antidepressant drugs induce adverse effects in male reproduction. Therefore, it is important to investigate alternative treatment for depression without adverse effects on the male reproductive system. The aim of this study was to determine the effect of pre-germinated brown rice (PGBR) on sperm quality, testicular structure and androgen receptor (AR) expression in rat model of depression. Male Sprague Dawley rats were divided into five groups including control (distilled water only), depression induced by forced swimming test (FST), FST + fluoxetine (antidepressant drug), FST + GABA (gamma-aminobutyric acid) (standard) and FST + PGBR. When compared with the control, sperm motility showed a significant decrease in FST + fluoxetine group. Sperm morphology also decreased significantly in depression and FST + fluoxetine groups. The morphological changes of seminiferous tubules showed significant increases in depression and FST + fluoxetine groups, while AR expression showed significant decreases in depression, FST + fluoxetine and FST + GABA groups. Interestingly, there were no significant differences in all sperm quality parameters, testicular structure and AR expression in FST + PGBR group. These findings reflect the recovery effects of PGBR treatment on sperm quality, morphological changes of seminiferous tubules and AR expression in stress-induced rats. Therefore, PGBR may potentially develop for the treatment for depression without adverse effect on male reproduction. © 2016 Blackwell Verlag GmbH.

We explored the effect of baculovirus P35 protein on apoptosis in the brain tissue of rats with acute cerebral infarction (ACI). A rat model of middle cerebral artery infarction was created. The rats were randomly divided into sham, model, and treatment groups. Baculovirus P35 protein was injected into the intracranial arteries of the treatment group rats. The rats in the model group were given an equal volume of phosphate-buffered saline. The rats were sacrificed after 72 h and the brain tissue was separated. The levels of caspase-3, Bcl-2, and Bax mRNA, the brain cell apoptosis index, and the infarct size were determined. After 72 h, the levels of caspase-3 and Bax mRNA in the model and treatment groups were significantly greater than in the sham group, and the levels of Bcl-2 mRNA were significantly smaller (P < 0.05). The levels of caspase-3 and Bax mRNA were significantly lower in the treatment group than in the model group, and the level of Bcl-2 mRNA was significantly greater (P < 0.05). Compared with the sham group, the brain tissue apoptosis index and the cerebral infarction area increased significantly in the model and treatment groups (P < 0.05). The brain tissue apoptosis index and cerebral infarction area in the treatment group were significantly lower than in the model group (P < 0.05). Baculovirus P35 protein can effectively inhibit brain cell apoptosis in rats with ACI. It delayed apoptosis and necrosis in subjects with ACI tissue and had a protective effect on brain tissue.

To evaluate the effect of oral cleaning using a mouthwash and a mouth moisturizing gel on the number of bacteria and moisture level of the tongue surface of older adults requiring nursing care. The 60 participants were randomly divided into groups according to their use of oral cleaning procedures as follows: group 1, mouthwash and a moisturizing gel (M + m); group 2, mouthwash (M); group 3, water and a moisturizing gel (W + m); and group 4, water (W). The number of anaerobic bacteria, tongue coating index and moisture level of the tongue surface were measured at baseline, and after 1 and 2 weeks after cleaning commenced to compare the effectiveness of oral cleaning among the groups. There was no significant difference in baseline measurements among the groups. The numbers of anaerobic bacteria decreased for all groups, and there were significant differences in the rates of decrease after 2 weeks between the M + m and W + m groups, M + m and W groups, and M and W groups. The tongue coating index decreased for all groups. There was no significant difference in the rate of decrease among the groups after 1 week, and there was a significant difference after 2 weeks between the M + m and W groups. The moisture levels of all groups increased, and there were significant differences after 2 weeks between the M + m and M groups, the M + m and W groups, and the W + m and W groups. The most effective cleaning technique was the combination of a mouthwash and a moisturizing gel. Geriatr Gerontol Int 2017; 17: 116-121. © 2015 Japan Geriatrics Society.

This study aims to compare the clinical outcomes and costs between percutaneous transhepatic biliary stenting (PTBS) and surgical bypass. We randomly assigned 142 patients with unresectable malignant biliary obstruction between 2005 and 2010 to receive PTBS or surgical bypass as palliative treatment. PTBS was successfully performed in 70 patients who formed the PTBS group (failed in 7 patients). Sixty five patients underwent surgical bypass treatment. Additional gastrojejunostomy was performed in five patients. The effectiveness of biliary drainage, hospital stay, complications, cost, survival time and mortality were compared. Patients in PTBS group had shorter hospital stay and lower initial and overall expense than the surgical group (p<0.05). There was no significant difference in effectiveness of biliary drainage (p=0.9307) or survival time between two groups (p=0.4826). Early complications of PTBS group was significantly lower than surgical group (3/75 vs. 11/65, p=0.0342). Late complication in PTBS group did not differ significantly from surgical group (9/70 vs. 6/65, p=0.6823). The survival curves in the two groups showed no significant difference (p=0.1032). PTBD is a better palliative treatment than surgical bypass for unresectable malignant biliary obstruction for its high effectiveness of biliary drainage and acceptable expense and complication.

This study aimed to investigate the effect of melatonin on the healing of colon anastomosis following chemotherapy. 32 rats were randomised into four groups: (a) control group (Group 1), which underwent sigmoid colon transaction and primary anastomosis; (b) melatonin group (Group 2), which received melatonin daily following anastomosis; (c) 5-fluorouracil (5-FU) group (Group 3), which received 5-FU for five days prior to anastomosis; and (d) 5-FU+melatonin group (Group 4), which received 5-FU for five days prior to anastomosis and melatonin daily following anastomosis. Anastomotic bursting pressures of the rats, which were sacrificed on postoperative day 7, were measured. The anastomotic segment was extracted for hydroxyproline, luminol and lucigenin measurements, and histopathological examination. Blood samples were obtained from the vena cava for measurement of tumour necrosis factor-alpha (TNF-α) and interleukin-1β (IL-1β) plasma levels. Bursting pressures of anastomosis and hydroxyproline levels were significantly higher in Groups 1 and 4 than in Group 3. Luminol and lucigenin levels were significantly lower in Groups 1 and 4 than in Group 3. In addition, TNF-α and IL-1β plasma levels were significantly lower in Groups 1 and 4 than in Group 3. Histopathological examination showed a significant decrease in inflammation and necrosis formation in Group 2 when compared to Group 1. The positive effect of melatonin was also seen in the rats that received 5-FU. Our study results showed that the adverse effects of chemotherapy on the mechanical, biochemical and histopathological parameters of anastomosis healing were attenuated through melatonin treatment.

The aim of the study was to analyze the treatment effect of transumbilical single-port laparoscopic varicocelectomy (TUSPLV) on recurrent varicocele (VC). In order to compare the surgical effects of TUSPLV to traditional retroperitoneal ligation of the internal spermatic vein, 64 patients with recurrent VC were enrolled and divided into the control group (n=30) and the observation group (n=34). Patients in the control group underwent surgery using traditional retroperitoneal ligation of the internal spermatic vein, while those in the observation group underwent surgery using TUSPLV. The results showed that the time of operation and bleeding volume in the observation group were significantly lower. The occurrence and recurrence rates of periprocedural complications were considerably lower in the observation group. Differences were statistically significant (P<0.05). In terms of the pregnancy rate, the difference between the 2 groups had no statistical significance (P>0.05). We concluded that employing TUSPLV to treat recurrent VC was safe and effective.

Objective: To investigate the clinical effect of dysmenorrhea in patients with adenomyosis treated by high intensity focused ultrasound(HIFU)ablation combined with gonadotropin-releasing hormone agonist(GnRH-a)and levonorgestrel-releasing intrauterine system(LNG-IUS). Methods: From April 2012 to December 2015, 477 cases of adenomyosis patients with dysmenorrhea were treated by HIFU in the Third Xiangya Hospital. Among them, some patients were treated with HIFU alone, some of them were treated with HIFU combined with GnRH-a and(or)LNG-IUS, thus were classified as H group, H+G group, H+M group and H+G+M group. The improvements of clinical results were compared among the four groups and the influencing factors of HIFU treatment for adenomyosis were also analyzed. Results: During the follow-up period, the overall effective rates of the treatment decreased with time, 3 months 89.4%(345/386), 12 months 84.0%(221/263), 24 months 74.2%(98/132), and the overall recurrence rate was 12.9%(39/303). The significant difference in the curative at 3 months[H group 83.7%(170/203), H+M group 95.0%(95/100), H+G group 100.0%(43/43), H+G+M group 96.8%(30/31)], 12 months[H group 79.4%(123/155), H+M group 93.2%(69/74), H+G group 11/12, H+G+M group 15/17], and 24 months[H group 68.0%(51/75), H+M group 96.4%(27/28), H+G group 6/12, H+G+M group 15/15]after HIFU treatment and recurrence rate[H group 19.0%(29/153), H+M group 3.3%(3/90), H+G group 19.4%(6/31), H+G+M group 4.5%(1/22)]were observed among the four groups( P <0.05). Pairwise comparison further showed that, in 3 months after the treatment, the effect of H group was significantly lower than those of H+M group and H+G group( P = 0.003, P =0.005); in 12 months after the treatment, the effect of H group was significantly lower than that of H+M group( P =0.006); while in 24 months after treatment, the effect of H group was significantly lower than that of H+G+M group( P =0.005), and the effect of H+G group was lower than that of H+G+M group( P = 0.001); and the recurrence rate of H group was significantly higher than that of H+M group( P <0.008). In patients of group H, the effect of HIFU was related to uterine size, the effect of patients with large uterine volume was significantly higher than that of small volume of uterine of patients( P =0.017, OR =2.739, 95% CI : 1.200- 6.251); with increasing of age, the improvement of dysmenorrhea had a increasing trend( P <0.05). Conclusions: HIFU combined with GnRH-a and(or)LNG-IUS could improve the treatment effect in relief of dysmenorrhea. Based on our results, individual treatment protocol should be selected for different patients.

This study was performed to investigate the effects of Crataegi fructus ethanol extracts (CFEEs) on the differentiation of 3T3-L1 cells, and to evaluate the effects of C. fructus powder (CFP) on lipid metabolism and its antiobesity effect in rats fed a high-fat and high-cholesterol (HFC) diet. Both in vitro and in vivo studies were performed for physiological activity and antiobesity effects on the serum, liver, and adipose tissues in obesity-induced rats. CFEEs showed significant inhibitory action on differentiation and triglyceride (TG) accumulation in 3T3-L1 mature cells in a dose-dependent manner. Subcutaneous, mesenteric, epididymal, and total adipose tissue weights of HFC diet group were heavier than those of normal diet (N) group, whereas those of groups fed CFP were significantly decreased. Levels of serum TGs, total cholesterol (TC), and low-density lipoprotein cholesterol were significantly decreased in the CFP groups than in the HFC group, whereas the serum high-density lipoprotein cholesterol level decreased in the HFC group and markedly increased in the CFP groups. TC and TG levels in the liver and adipose tissues were significantly lower in CFP groups than in the HFC groups. In addition, feeding with CFP significantly reduced the occurrence of fatty liver deposits and steatosis, and inhibited an HFC diet-induced increase in adipocyte size. These results suggest that C. fructus may improve lipid metabolism in the serum, liver, and adipose tissue, and may potentially reduce lipid storage.

To determine the effects of pinealectomy on endometrial explants in rats and evaluate the activity of superoxide dismutase (SOD) and catalase (CAT) and the levels of malondialdehyde (MDA) in the rat endometriosis model. Rats with experimentally induced endometriosis were randomly divided into three groups after second-look laparotomies. Group 1 (pinealectomy, n = 8) and Group 2 (pinealectomy+melatonin, n = 8) underwent pinealectomies after the second-look laparotomies. Group 3 was presented as control group (vehicle solution+without pinealectomy (n = 6)). Melatonin was administered intraperitoneally for 4 weeks in Group 2, whereas an equal volume of vehicle solution was given to Groups 1 and 3. Evaluation of the volume of the endometrial explants, histopathological examination and preservation of explant epitheliums according to the scoring system were undertaken. There was a statistically significant increase in spherical explant volumes of Group 1 compared to Groups 2 and 3. In Group 1, the level of MDA was significantly higher and SOD and CAT activity was significantly lower compared to Groups 2 and 3. A statistically significant increase in the epithelial lining scores of explants was noted in Group 1 compared to Groups 2 and 3. The effects of pinealectomy on the progression of endometriosis explants were reversed by melatonin. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

BACKGROUND Malondialdehyde (MDA) is an oxidant that causes damage to membranes, DNA, proteins, and lipids at the cellular level. Antioxidants minimize the effects of oxidants and thus help in formation of healthy granulation tissues with higher level of hydroxyproline and total protein. This study compared the effect of limited access dressing (LAD) with conventional closed dressing biochemically and histopathologically. METHODS Seventy-two 12-65 years old burn patients with mean wound size of 14 cm2 were divided to two groups of LAD (n=37), and conventional dressing groups (n=35). Various biochemical parameters were measured in granulation tissue. Histopathological analysis of the granulation tissue was studied too. RESULTS LAD group showed significant increase in hydroxyproline, total protein, GSH, and GPx and decrease in MDA levels compared to conventional dressing group. A significant negative correlation between GSH and MDA was noted in LAD group, but in conventional dressing group there was no significant correlation. A significant negative correlation between GPx and MDA was noticed in LAD group, but in conventional dressing group was not significant. There was a histologically fewer inflammatory cells, increased and well organized extracellular matrix deposit, more angiogenesis in LAD group after 10 days while the difference was significant between the groups. CONCLUSION Our study showed a significant reduction in oxidative stress biomarker of MDA, increase in hydroxyproline, total protein, antioxidants and amount of ECM deposition, number of blood vessels and a decrease in the amount of inflammatory cells and necrotic tissues in LAD group indicating the better healing effect of burn wounds.

This prospective study aimed to compare the intraosseous (IO) and intravenous (IV) effects of propofol on selected blood parameters and physiological variables during general anesthesia in rabbits. Thirty New Zealand White rabbits were studied. Six rabbits received IV propofol (group 1) and another 6 rabbits, were injected propofol intraosseously (Group 2) for 30 minutes (experimental groups). Rabbits of the third and fourth groups received IV and IO normal saline at the same volume given to the experimental groups, respectively. In the fifth group IO cannulation was performed but neither propofol nor normal saline were administered. Blood profiles were assayed before induction and after recovery of anesthesia. Heart and respiratory rates, rectal temperature, saturation of peripheral oxygen and mean arterial blood pressure were recorded. Heart rate increased significantly 1 to 5 minutes after induction of anesthesia in experimental groups (P < 0.05). Although mean arterial blood pressure decreased significantly from baseline, values remained above 60 mm Hg (P < 0.05). Respiratory rate decreased significantly in experimental groups, but remained higher in group 2 (P < 0.05). The lymphocyte count decreased significantly in group 1 (P < 0.05). The concentration of alkaline phosphatase in all rabbits, aspartate aminotransferase and gamma-glutamyl transferase in the first group and gamma-glutamyl transferase in the third group increased significantly (P < 0.05). Total bilirubin decreased significantly in group 2 (P < 0.05). All measured values remained within normal limits. Based on the least significant physiological, hematological and biochemical effects, the IO injection of propofol appears to be safe and suitable method of anesthesia in rabbits with limited vascular access.

Background Biventricular (BIV) pacing can improve cardiac function in heart failure by altering the mechanical and electrical substrates. We investigated the effect of BIV versus right ventricular (RV) pacing on the normal heart. Methods and Results Male New Zealand White rabbits (n=33) were divided into 3 groups: sham-operated (control), RV pacing, and BIV pacing groups. Four weeks after surgery, the native QT (p=0.004) interval was significantly shorter in the BIV group compared to the RV or sham-operated groups. Also, compared to rabbits in the RV group, rabbits in the BIV group had shorter RV ventricular effective refractory period (VERP) at all cycle lengths, and shorter LV paced QT interval during the drive train of stimuli and close to refractoriness (p<0.001 for all comparisons). Protein expression of the KVLQT1 was significantly increased in the BIV group compared to the RV and control groups, while protein expression of SCN5A and connexin43 was significantly decreased in the RV compared to the other study groups. Erg protein expression was significantly increased in both pacing groups compared to the controls. Conclusions In this rabbit model, we demonstrate a direct effect of BIV but not RV pacing on shortening the native QT interval as well as the paced QT interval during burst pacing and close to the VERP. These findings underscore the fact that the effect of BIV pacing is partially mediated through direct electrical remodeling and may have implications as to the effect of BIV pacing on arrhythmia incidence and burden.

Background The intraocular pressures and biomechanical parameters measured by the ocular response analyzer make the analyzer a useful tool for the diagnosis and management of anterior segment disease. This observational study was designed to investigate the effect of topical anesthesia on the parameters measured by the ocular response analyzer: corneal hysteresis, corneal resistance factor, Goldmann-correlated intraocular pressure (IOPg), and corneal-compensated intraocular pressure (IOPcc). Methods Two sets of measurements were made for 78 eyes of 39 subjects, approximately 1 week apart. In session 1, each eye of each subject was randomized into one of three groups: polyvinyl alcohol (0.5%), tetracaine hydrochloride (0.5%), or oxybuprocaine hydrochloride (0.4%). In session 2, eyes that were in the polyvinyl alcohol group in session 1 were assigned to the tetracaine group, those in the tetracaine group in session 1 were assigned to oxybuprocaine group, and those in the oxybuprocaine group in session 1 were assigned to the polyvinyl alcohol group. For both sessions, each subject first had his or her central corneal thickness assessed with a specular microscope, followed by measurements of intraocular pressure and corneal biomechanical parameters with the Ocular Response Analyzer. All measurements were repeated for 2 minutes and 5 minutes following the instillation of either polyvinyl alcohol, tetracaine, or oxybuprocaine. The level of statistical significance was 0.05. Results Polyvinyl alcohol, tetracaine hydrochloride, and oxybuprocaine hydrochloride had no statistically significant (P > 0.05) effect on any of the biomechanical parameters of the cornea. There was no statistically significant effect on either IOPg (P > 0.05) or IOPcc (P > 0.05) 2 minutes after the eye drops were instilled in either session. Five minutes after the eye drops were instilled, polyvinyl alcohol showed no statistically significant effect on either IOPg (P > 0.05) or IOPcc (P > 0.05) in either session. Oxybuprocaine and tetracaine caused statistically significant (P < 0.05) reductions in IOPg in session 1, but only tetracaine had a significant (P < 0.05) effect in session 2. Tetracaine also caused a statistically significant (P < 0.05) reduction in IOPcc in session 1. Conclusion The statistically significant effect of topical anesthesia on IOPg varies with the anesthetic used, and while this effect was statistically significant in this study, the small effect is probably not clinically relevant. There was no effect on any of the biomechanical parameters of the cornea. PMID:22791966

Polyphenol-rich grape seeds have a beneficial effect on human health. The present study was performed to investigate the effects of grape seeds on antioxidant activities in rats. Male Sprague-Dawley rats were randomly divided into a control diet group (C), a high-fat diet group (HF), a 5% grape seed-supplemented control diet group (G), and a 5% grape seed-supplemented high-fat diet group (HG). Dietary supplementation with grape seeds reduced serum concentrations of lipid peroxides compared with those in the C and HF groups. The hepatic level of lipid peroxides decreased significantly in the grape seed groups compared with that in the C and HF groups. Superoxide dismutase activity in the G group increased significantly compared with that in the C group. Catalase activity tended to be higher by feeding grape seeds. The grape seed diet increased glutathione peroxidase activity in the C group. Glutathione-S-transferase activity increased significantly in the G group compared with that in the C group. Hepatic content of total glutathione increased significantly in the HG group but decreased significantly in the HF group. The ratio of reduced glutathione and oxidized glutathione increased by feeding the grape seed diet. Total vitamin A concentration was significantly higher in HG group than in other groups. Liver tocopherol content of the G and HG groups was significantly higher than that of the control groups. These results suggest that dietary supplementation with grape seeds is beneficial for suppressing lipid peroxidation in high fat-fed rats. PMID:22413034

Testicular torsion is an emergency condition that causes testicular injury. Any treatment opportunity reducing the destructive effect of testicular torsion is important for the future life of patients. In this experimental study we investigated the protective effect of mannitol on ischemia-reperfusion (I/R) injury in a rat testes torsion model. In total, 32 male Sprague Dawley rats were included. Four experimental groups included eight rats each. Group A was a sham group in which the right testis was brought out through a scrotal incision and then replaced in the scrotum without torsion. In Group B, the right testis was torsioned, by rotating 720° clockwise and fixed to the scrotum with no treatment. In Group C, the same testicular torsion process was performed with saline infusion just after testicular torsion. In group D, mannitol infusion was used just after testicular torsion. Testicles were detorsioned after 3 h and left inside for more than 2 h before orchiectomy. Histopathological, immunohistochemical, and biochemical analyses were performed. Testicular architecture was disturbed significantly in the torsion groups without mannitol infusion. However, testicular tissue structure was significantly better in the mannitol-treated group, demonstrating a protective effect. Similar findings were also shown for the proliferating cell nuclear antigen (PCNA) index and antioxidant activity; both were higher in the mannitol group than in the no-treatment and saline groups (p < 0.01). The apoptotic index was also significantly lower in the mannitol-treated group compared with the no treatment and saline groups (p < 0.01). The seminiferous tubule structure in testicular torsion without mannitol treatment was significantly disturbed, whereas the structural disruption was considerably less in the mannitol group. Mannitol treatment also decreased reactive oxygen radical levels significantly and was able to decrease apoptosis. These results were consistent with other organ model studies that evaluated the protective effects of mannitol treatment in I/R injury. Mannitol infusion had a protective effect against I/R injury in testicular torsion in rats. This experimental study may guide clinicians to evaluate the effectiveness of mannitol in human testicular torsion. Copyright © 2016 Journal of Pediatric Urology Company. Published by Elsevier Ltd.

This study aims to compare the clinical outcomes and costs between endoscopic biliary stenting (EBS) and percutaneous transhepatic biliary stenting (PTBS). We randomly assigned 112 patients with unresectable malignant biliary obstruction 2006 and 2011 to receive EBS or PTBS with self-expandable metal stent (SEMS) as palliative treatment. PTBS was successfully performed in 55 patients who formed the PTBS group (failed in 2 patients). EBS was successfully performed in 52 patients who formed the EBS group (failed in 3 patients). The effectiveness of biliary drainage, hospital stay, complications, cost, survival time and mortality were compared. Patients in PTBS group had shorter hospital stay and lower initial and overall expense than the BBS group (P < 0.05). There was no significant difference in effectiveness of biliary drainage (P = 0.9357) or survival time between two groups (P = 0.6733). Early complications occurred in PTBS group was significantly lower than in EBS group (3/55 vs 11/52, P = 0.0343). Late complications in the EBS group did not differ significantly from PTBS group (7/55 vs 9/52, P = 0.6922). The survival curves in the two groups showed no significant difference (P = 0.5294). Conclusions: 3.

Investigate the effect of percutaneous radiofrequency compared to a sham procedure, applied to the ramus communicans for treatment of lumbar disc pain. Randomized sham-controlled, double-blind, crossover, multicenter clinical trial. Multidisciplinary pain centres of two general hospitals. Sixty patients aged 18 or more with medical history and physical examination suggestive for lumbar disc pain and a reduction of two or more on a numerical rating scale (0-10) after a diagnostic ramus communicans test block. Treatment group: percutaneous radiofrequency treatment applied to the ramus communicans; sham: same procedure except radiofrequency treatment. pain reduction. Secondary outcome measure: Global Perceived Effect. No statistically significant difference in pain level over time between the groups, as well as in the group was found; however, the factor period yielded a statistically significant result. In the crossover group, 11 out of 16 patients experienced a reduction in NRS of 2 or more at 1 month (no significant deviation from chance). No statistically significant difference in satisfaction over time between the groups was found. The independent factors group and period also showed no statistically significant effects. The same applies to recovery: no statistically significant effects were found. The null hypothesis of no difference in pain reduction and in Global Perceived Effect between the treatment and sham group cannot be rejected. Post hoc analysis revealed that none of the investigated parameters contributed to the prediction of a significant pain reduction. Interrupting signalling through the ramus communicans may interfere with the transition of painful information from the discs to the central nervous system. Methodological differences exist in studies evaluating the efficacy of radiofrequency treatment for lumbar disc pain. A randomized, sham-controlled, double-blind, multicenter clinical trial on the effect of radiofrequency at the ramus communicans for lumbar disc pain was conducted. The null hypothesis of no difference in pain reduction and in Global Perceived Effect between the treatment and sham group cannot be rejected. © 2016 The Authors.

We developed laparoscopic-assisted rectus sheath block (LRSB) as a novel technique and report on its safety and effectiveness. Patients were randomly enrolled to an LRSB or control group (n=19 each). In the LRSB group, after the umbilical wound was closed, local anesthetic was injected transcutaneous at each of 4 sites (3 cm above and below the umbilicus bilaterally) with 10 mL of 0.25% levobupivacaine, laparoscopically. The control group received conventional postoperative pain management. The primary endpoint was visual analogue scale (VAS) pain score at the end of surgery. Secondary endpoints were VAS and Prince Henry pain scale after surgery, number of administrations of analgesics, and side effects of anesthesia. No significant differences in background were seen between groups. VAS at the end of surgery was significantly lower in the LRSB group than in controls (P<0.01). VAS and Prince Henry pain scale were significantly lower in the LRSB group from soon after surgery to postoperative day 2. No complications related to LRSB were encountered. LRSB was particularly effective at the end of surgery and pain scores were significantly lower in the LRSB group long after surgery. Our study shows LRSB is effective and safe for laparoscopic abdominal surgery.

This study aims to investigate the effect of captopril and losartan on the electrophysiology of myocardial cells parameters in ventricular vulnerable period and effective refractory period of myocardial ischemia rats. 96 wistar rats were enrolled in the study and divided into six groups: Captopril myocardial ischemia group, losartan myocardial ischemia group, myocardial ischemia control group, captopril normal group, losartan normal group and normal control group (n=16). We observed morphological changes of myocardial tissue in each group. The cardiac electrophysiological parameters in effective refractory period of each group were measured. Creatine kinase (CK), alanine aminotransferase (GOT), lactate dehydrogenase (LDH), the expression of Cardiotrophin 1 (CT-1) and malonaldehyde (MDA) were detected. Compared the losartan and captopril group with the control group, (P<0.05). Losartan and captopril can shorten the ventricular vulnerable period of the normal group and ischemic group. There was no interaction effect between losartan and captopril group and the acute myocardial ischemia group. The effect of losartan and captopril on time window in ventricular vulnerable period showed that compared with the control group (P<0.05). Losartan and captopril had a significant effect on prolonged effective refractory period of normal and ischemic rats. There was no interaction effect between losartan and captopril group and the acute myocardial ischemia group. Compared with the myocardial ischemia control group, CK, GOT, LDH and MDA decreased in captopril and losartan myocardial ischemia groups (P<0.05). Losartan and captopril had a significant effect on prolonged effective refractory period and shorten ventricular vulnerable period, they can also effectively prevent arrhythmias.

To investigate the effect of natural hirudin combined with hyperbaric oxygen therapy on the survival of transplanted random-pattern skin flap in rats. A random-pattern skin flap in size of 10.0 cm×2.5 cm was elevated on the dorsum of 72 Sprague Dawley rats. Then the 72 rats were randomly divided into 4 groups ( n =18) according to the therapy method. At immediate and within 4 days after operation, the rats were treated with normal saline injection in control group, normal saline injection combined with hyperbaric oxygen treatment in hyperbaric oxygen group, the natural hirudin injection in natural hirudin group, and the natural hirudin injection combined with hyperbaric oxygen treatment in combined group. The flap survival was observed after operation, and survival rate was evaluated at 6 days after operation. The skin samples were collected for histological analysis, microvessel density (MVD) measurement, and evaluation of tumor necrosis factor α (TNF-α) expression level by the immunohistochemical staining at 2 and 4 days after operation. Partial necrosis occurred in each group after operation, and the flap in combined group had the best survival. The survival rate of flap was significantly higher in hyperbaric oxygen group, natural hirudin group, and combined group than that in control group, and in combined group than in hyperbaric oxygen group and natural hirudin group ( P <0.05). There was no significant difference between hyperbaric oxygen group and natural hirudin group ( P >0.05). At 2 days, more microvascular structure was observed in hyperbaric oxygen group, natural hirudin group, and combined group in comparison with control group; while plenty of inflammatory cells infiltration in all groups. At 4 days, the hyperbaric oxygen group, natural hirudin group, and the combined group still showed more angiogenesis. Meanwhile, there was still infiltration of inflammatory cells in control group, inflammatory cells in the other groups were significantly reduced when compared with at 2 days. At 2 days, the MVD was significantly higher in hyperbaric oxygen group, natural hirudin group, and combined group than that in control group ( P <0.05); the expression of TNF-α was significantly lower in hyperbaric oxygen group, natural hirudin group, and combined group than that in control group ( P <0.05). There was no significant difference in above indexes between hyperbaric oxygen group, natural hirudin group, and combined group ( P >0.05). At 4 days, the MVD was significantly higher in hyperbaric oxygen group, natural hirudin group, and combined group than that in control group, in natural hirudin group and combined group than in hyperbaric oxygen group ( P <0.05). The expression of TNF-α was significantly lower in hyperbaric oxygen group, natural hirudin group, and combined group than that in control group, in combined group than in natural hirudin group and hyperbaric oxygen group ( P <0.05). Hyperbaric oxygen and natural hirudin therapy after random-pattern skin flap transplantation can improve the survival of flaps. Moreover, combined therapy is seen to exhibit significant synergistic effect. This effect maybe related to promotion of angiogenesis and the reduction of inflammation response.

In-service education affects the quality of cancer care directly. Using classroom teaching to deliver in-service education is often ineffective due to participants' large workload and shift requirements. This study evaluated the learning effectiveness of different teaching methods in the dimensions of knowledge, attitude, and learning satisfaction. This study used a quasi-experimental study design. Participants were cancer ward nurses working at one medical center in northern Taiwan. Participants were divided into an experimental group and control group. The experimental group took an e-learning course and the control group took a standard classroom course using the same basic course material. Researchers evaluated the learning efficacy of each group using a questionnaire based on the quality of cancer nursing care learning effectiveness scale. All participants answered the questionnaire once before and once after completing the course. (1) Post-test "knowledge" scores for both groups were significantly higher than pre-test scores for both groups. Post-test "attitude" scores were significantly higher for the control group, while the experimental group reported no significant change. (2) after a covariance analysis of the pre-test scores for both groups, the post-test score for the experimental group was significantly lower than the control group in the knowledge dimension. Post-test scores did not differ significantly from pre-test scores for either group in the attitude dimension. (3) Post-test satisfaction scores between the two groups did not differ significantly with regard to teaching methods. The e-learning method, however, was demonstrated as more flexible than the classroom teaching method. Study results demonstrate the importance of employing a variety of teaching methods to instruct clinical nursing staff. We suggest that both classroom teaching and e-learning instruction methods be used to enhance the quality of cancer nursing care education programs. We also encourage that interactivity between student and instructor be incorporated into e-learning course designs to enhance effectiveness.

An attempt was made to evaluate the effect of aqueous extract of wild mint (Mentha Ingifolia) on the overall performance of broiler chicks at NWFP Agricultural University, Peshawar in July 2005. Three levels of fresh wild mint infusion at the rate of 50, 40 and 30 mL L(-1) of fresh drinking water were provided to chicks in groups A, B and C, respectively and group D was kept as control, each group was replicated four times with 10 chicks per replicate, reared for 35 days, in an open sided house in cages of the same size. No vaccination was practiced. Data were recorded daily for feed intake, water intake and for weight gain on weekly basis. Feed conversion efficiency, dressing percentage, percent mortality, weight of different body organs (breast, thigh and leg), giblets (liver, heart and gizzard), intestine and economics for each group was calculated at the end of experimental period. It was found that group B receiving 40 mL L(-1) of wild mint infusion in drinking water had a significant (p < 0.05) effect on mean body weight gain, feed intake, water intake, feed conversion efficiency, dressing percentage and weight of different body organs (breast, thigh and leg). Significant (p < 0.05) differences were also found in mortality, highest mortality was observed in group D (10%) as compared with groups A, B and C, however there was no significant effect on giblets (liver, heart, gizzard), intestine and weight of abdominal fat. Mean feed cost and gross return was significantly (p < 0.05) effected for group B. Feed cost was lower and gross return was significantly (p < 0.05) higher for group B than other treated groups and control.

Neurotoxicity is one of the major effects of tributyltin (TBT). The effects on the next generation of F(1) rats exposed to TBT via the placenta and their dams' milk may be stronger than those on adults. Pregnant Wister rats were exposed to TBT at 0 and 125 ppm in their food. Half of the female F(1) rats in both groups were exposed to TBT at 125 ppm in their food from 9 to 15 weeks of age. Female F(1) rats were divided into the following groups: the control-control (CC) group, with no exposure; the TBT-control (TC) group, exposed to TBT via the placenta and their dams' milk; the control-TBT (CT) group, exposed to TBT via their food from 9 to 15 weeks of age; and the TBT-TBT (TT) group, exposed to TBT via the placenta, their dams' milk, and their food (n = 10/group). After administration, an open-field test and prepulse inhibition (PPI) test were performed at 15 weeks of age. The mean body weights of the TC and TT groups were significantly lower than that of the CC group from 9 to 15 weeks of age. The mean relative thymus weight of the TC and TT groups was significantly lower than that of the CC group. In the open-field test, a marked decrease in the total locomotion distance was observed in the TT group. The mean values in the TT and TC groups were significantly lower than that in the CC group. For the locomotion distance between 15 and 20 min, the mean values in the CT, TC, and TT groups were significantly lower than that in the CC group. The mean locomotor distance between 25 and 30 min in the TT group was significantly lower than that in the CC and TC groups. The mean values of instances of wall rearing in the TC, CT, and TT groups were significantly lower than that in the CC group. The mean value of face washing or body washing in the TT group was significantly lower than that in the CT group. There were no significant differences in indexes of the PPI test. Exposure to TBT via the placenta and their dams' milk inhibited the development of F(1) rats, which continued after weaning. Inhibition of the rats' activity induced by exposure to TBT via the placenta and their dams' milk and/or via their food was suggested. The effects were most evident in the TT group.

The University of Minnesota: Simulations, Exercises and Effective Education: Preparedness and Emergency Response Learning Center uses simulations, which allow trainees to participate in realistic scenarios, to develop and evaluate competency. In a previous study, participants in Disaster in Franklin County: A Public Health Simulation demonstrated that prior bioterrorism and emergency readiness training (BT/ER) is significantly associated with better performance in a simulated emergency. We conducted a second analysis with a larger data set, remapping simulation questions to the Public Health Preparedness and Response Core Competency Model, Version 1.0. We performed an outcome evaluation of the impact of public health preparedness training. In particular, we compared individuals with significant BT/ER training to individuals without training on the basis of performance in a simulated emergency. We grouped participants as group 1 (≥45 hours of BT/ER training) and group 2 (<45 hours). Dependent variables included effectiveness of chosen responses within the gaming simulation, which was measured as the proportion of questions answered correctly for each participant. The relationship of effectiveness with significant BT/ER training was estimated using either multiple linear or logistic regression. For overall effectiveness, group 1 had 2% more correct decisions, on average, than group 2 (P < .001). Group 1 performed significantly better, on average, than group 2 for competency 1.1 (P = .001) and competency 2.3 (P < .001). However, group 1 was significantly worse on competency 1.2 than group 2. Results indicate that prior training is significantly associated with better performance in a simulated emergency using gaming technology. Effectiveness differed by competency, indicating that more training may be needed in certain competency areas. Next steps to enhancing the usefulness of simulations in training should go beyond questioning if the learner learned and included questions related to the organizational factors that contributed to simulation effectiveness, and attributes of the simulation that encouraged competency and capacity building.

To compare the effects of vibration therapy and massage in prevention of DOMS. Pre-test and Post-test Control-Group Design was used, 45 healthy female non athletic Subjects were recruited and randomly distributed to the three groups (15 subject in each group). After the subject's initial status was measured experimental groups received vibration therapy (50 Hz vibration for five minutes) or massage therapy (15 minutes) intervention and control group received no treatment, just prior to the eccentric exercise. Subjects were undergoing the following measurements to evaluate the changes in the muscle condition: muscle soreness (pain perception), Range of Motion (ROM), Maximum Isometric Force (MIF), Repetition maximum (RM), Lactate dehydrogenase (LDH) and Cretain Kinase (CK) level. All the parameters except LDH, CK and 1RM were measured before, immediately post intervention, immediately post exercise, 24 hours post exercise, 48 hours post exercise and 72 hours post exercise. LDH, CK and 1 RM were measured before and 48 hours post exercise. Muscle soreness was reported to be significantly less for experimental (vibration and massage) group (p=0.000) as compared to control group at 24, 48, and 72 hours of post-exercise. Experimental and control group did not show any significant difference in MIF immediate (p=0.2898), 24 hours (p=0.4173), 48 hours (p=0.752) and 72 hours (p=0.5297) of post-exercise. Range of motion demonstrated significant recovery in experimental groups in 48 hours (p=0.0016) and 72 hours (p=0.0463). Massage therapy showed significant recovery in 1RM (p=0.000) compared to control group and vibration therapy shows significantly less LDH level (p=0.000) 48 hours of post exercise compare to control group. CK at 48 hours of post exercise in vibration group (p=0.000) and massage group showed (p=0.002) significant difference as compared to control group. Vibration therapy and massage are equally effective in prevention of DOMS. Massage is effective in restoration of concentric strength (1 RM). Yet vibration therapy shows clinically early reduction of pain and is effective in decreasing the level of LDH in 48 hours post exercise periods.

The aim of the present study was to evaluate the effect of chemical disinfection, autoclave, and microwave sterilization on some of the key properties of elastomers. Five polyvinylsiloxane elastomeric impression materials were evaluated. Forty samples were fabricated from each material. The samples were randomly selected and assigned to four experimental groups with 50 samples each: group I, control; group II,chemical disinfection; group III, autoclave sterilization; and group IV, microwave sterilization. The differences in the mean values were contrasted and compared with the control group and analyzed using two-way analysis of variance (P < 0.05). The results showed that chemical disinfection and autoclave sterilization had no significant effect on the tensile strength and surface roughness, whereas microwave sterilization showed a statistically-significant reduction in tensile strength, and an increase in surface roughness. None of the disinfection and sterilization techniques had a significant effect on wettability. However, autoclave and microwave sterilization resulted in an increase in hydrophilicity of all the materials tested. Chemical disinfection and autoclave sterilization had no statistically-significant effect on the tested properties of elastomers, thus autoclave sterilization can be considered as an alternative and an effective mode of disinfection and sterilization to eliminate all forms of disease causing microorganisms from dental impressions. © 2016 John Wiley & Sons Australia, Ltd.

The objective is to examine the effects of reminiscence therapy (RT) on total, episodic and semantic autobiographical memory in amnestic mild cognitive impairment (aMCI) and Alzheimer's disease (AD) groups, testing the effects of RT on different stages of autobiographical memory, and its effectiveness at follow-up. A sample composed of 43 aMCI (27 treatments, 16 controls) and 30 AD (15 treatments, 15 controls) subjects were evaluated with the Autobiographical Memory Interview (AMI) test. The RT consisted of 10 sessions lasting 60 minutes each. Both groups, aMCI and AD, showed significant effects on overall autobiographical memory; aMCI showed significant main effects on episodic and semantic autobiographical memory in the treatment group, increasing scores in both cases. For AD, significant effects were observed on autobiographical episodic memory, showing an increase in the treatment group from Time 1 to follow-up; semantic memory showed a decrease in the control group from Time 1 to follow-up. Results show that RT implementation and follow-up are effective in increasing autobiographical memory in subjects with aMCI and AD. © 2015 International Union of Psychological Science.

This 2-week interventional study involved a randomized allocation of subjects into three groups: Group A (daily ingestion of 350 g vegetables cooked without water using multi-ply [multilayer-structured] cookware), Group B (daily ingestion of 350g vegetables; ordinary cookware) and Group C (routine living). Before and after intervention, each subject underwent health examination with 24-h urine sampling. Blood vitamin C significantly increased after intervention from the baseline in Group A (P < 0.01) and Group B (P < 0.05). β-Carotene levels also increased significantly after intervention in Group A (P < 0.01) and Group B (P < 0.01). Oxidized low-density lipoprotein decreased significantly after intervention in Group A (P < 0.01). In Group A, 24-h urinary potassium excretion increased significantly (P < 0.01) and 24-h urinary sodium (Na)/K ratio improved significantly (P < 0.05) after intervention. In conclusion, a cooking method modification with multi-ply cookware improved absorption of nutrients from vegetables and enhanced effective utilization of the antioxidant potentials of vegetable nutrients.

The purpose of this trial was to examine the feasibility and efficacy of computerized cognitive exercises from Scientific Brain Training (SBT), compared to the computer game Tetris as an active placebo, in a pilot study of adolescents with attention-deficit/hyperactivity disorder (ADHD). Eighteen adolescents with ADHD were randomized to treatment or control intervention for 7 weeks. Outcome measures were cognitive test, symptom, and motivation questionnaires. SBT and Tetris were feasible as home-based interventions, and participants' compliance was high, but participants perceived both interventions as not very interesting or helpful. There were no significant group differences on cognitive and ADHD-symptom measures after intervention. Pre-post intra-group measurement showed that the SBT had a significant beneficial effect on sustained attention, while the active placebo had significant beneficial effects on working memory, both with large effect sizes. Although no significant differences were found between groups on any measure, there were significant intra-group changes for each group.

We investigated the effect of autogenic training (AT) on cardiac autonomic nervous activity in fire services workers with the use of the questionnaire of the Japanese-language version of Impact of Event Scale-Revised (IES-R-J) and indexes of heart rate variability. We studied 22 male fire services workers who were divided into posttraumatic stress disorder (PTSD)-related stress group (n=10) and control group (n=12). They underwent AT twice or three times a week for 2 months. Posttraumatic stress disorder-related stress group showed a significantly higher cardiac sympathetic nervous activity and a significantly lower cardiac parasympathetic nervous activity than control group at baseline. Autogenic training significantly decreased cardiac sympathetic nervous activity and significantly increased cardiac parasympathetic nervous activity in both groups. These changes were accompanied by a significant decrease in the total points of IES-R-J. Autogenic training is effective for ameliorating the disturbance of cardiac autonomic nervous activity and psychological issues secondary to PTSD.

[Purpose] The purpose of this study was to implement combined muscle strengthening and proprioceptive exercises to examine the effects of combined exercises on functional ankle instability. [Subjects and Methods] Experiments were conducted with 30 adult males and females. The study subjects were randomly assigned to either a control group (Group A), a muscle strengthening exercise group (Group B), or a combined muscle strengthening and proprioceptive exercise group (Group C) consisting of 10 subjects each. In Group A, measurements were only conducted before and after the experiment without any intervention, whereas the exercise programs for Group B and Group C were implemented three days per week for four weeks. [Results] Muscle strength showed significant increases in Groups B and C compared with the control group during plantar flexion, dorsiflexion, inversion, and eversion. The Cumberland ankle instability tool showed significant increases in Group B and Group C compared with Group A and significant increases in Group C compared with Group B. [Conclusion] Applying combined muscle strengthening and proprioceptive exercises to those who have functional ankle instability is more effective than applying only muscle strengthening exercises.

Our study aimed to investigate the effect of mirtazapine on bone metabolism in the orchidectomized rat model. Rats were divided into three groups. A sham-operated control group (SHAM group) and a control group after orchidectomy (ORX group) received the standard laboratory diet (SLD). An experimental group after orchidectomy (ORX MIRTA group) received SLD enriched with mirtazapine for 12 weeks. Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry. Bone marker concentrations of osteoprotegerin (OPG), amino-terminal propeptide of procollagen type I, bone alkaline phosphatase (BALP), sclerostin and bone morphogenetic protein 2 were examined in bone homogenate. The femurs were used for biomechanical testing. Compared with the control ORX group, we found a lower BMD in the ORX MIRTA group. The differences were statistically significant, although not in the lumbar vertebrae. BMD was lower in the MIRTA group, suggesting a preferential effect on cortical bone. However, although the thickness of the diaphyseal cortical bone was not different, the fragility in the femoral neck area was statistically significantly different between the groups in biomechanical testing. Regarding the bone metabolism markers, there was a significant decrease in OPG and BALP levels, suggesting a reduction in osteoid synthesis. The results suggest that prolonged use of mirtazapine may have a negative effect on the synthesis of bone and on its mechanical strength, especially in the femoral neck. Further studies are warranted to establish whether mirtazapine may have a clinically significant adverse effect on bone exclusively in the model of gonadectomized rats, or whether the effect occurs also in the model of gonadally intact animals and in respective human models. © 2015 S.

In this study, we evaluated the hypolipidemic and antioxidative effects of biotransformed soybean powder (BTS; Phellinus baumii-fermented soybean) on lipid metabolism in rats. Sprague-Dawley (SD) male rats were divided into basal diet group (BA), high fat diet group (HF), high fat diet containing 10% BTS group (10 BTS), and high fat diet containing 20% BTS group (20 BTS). Changes in the content of various isoflavones, including daidzein and genistein, within the soybean after fermentation to BTS were investigated. The levels of daidzein and genistein were 149.28 μg/g and 364.31 μg/g, respectively. After six weeks experimental period, Food efficiency ratio in the 10 and 20 BTS group was significantly lower than the HF group (P<0.05). Total serum levels of cholesterol, triglycerides, low-density lipoprotein cholesterol, and atherogenic index ratio in the 10 or 20 BTS group were significantly lower than the HF group. The levels of alanine aminotransferase, aspartate aminotransferase and thiobarbituric acid reactive substance were significantly lower in the groups that received 10% and 20% BTS than the HF. The activities of SOD and CAT were significantly higher in the 10 and 20 BTS group than the HF group. The activity of XO in the 10 and 20 BTS group was significantly lower than in the HF group by 20% and 23%, respectively. In conclusion, these data suggest that BTS is an effective agent in improving lipid metabolism and antioxidant enzyme system. PMID:24471117

This study aims to study the effect of Rho kinase inhibitor fasudil on the expression endothelin-1 (ET-1) and nitric oxide (NO) in rats with hypoxic pulmonary hypertension (HPH). Twenty-four male SD rats were randomly divided into three groups: control group, model group (HPH group) and HPH+fasudil group. The rat HPH model was established by intermittent hypoxia (IH) at atmospheric pressure. Mean pulmonary artery pressure (mPAP), right ventricular hypertrophy index (RVHI), ET-1 and NO levels, and pulmonary vascular structural changes were observed in all groups. MPAP, RVHI and ET-1 levels were significantly higher in HPH group than in control group, while NO was significantly lower than in control group. In addition, mPAP, RVHI and ET-1 were significantly lower in the HPH+fasudil group than in the HPH group. In the HPH group, ET-1 level was significantly and positively correlated with mPAP and RVHI, NO was negatively correlated with mPAP and RVHI levels, and ET-1 level was significantly and negatively correlated with NO level. In the HPH group, pulmonary arteriolar walls were generally thickened, and lumen stenosis was obvious; while after fasudil treatment, pulmonary arteriolar wall thickening and stenosis degree were significantly reduced. Fasudil can significantly reduce ET-l level and increase NO level in HPH rats, suppressing the development of pulmonary arterial hypertension.

Inflammation response and oxidative stress promote the occurrence and development of multiple-organ dysfunction syndrome (MODS). Eighty MODS rats with third-degree burns were divided randomly into 4 groups: insulin, ethyl pyruvate (EP), insulin combined with EP, and control. Blood levels of glucose, alanine aminotransferase (ALT), creatine (CRE), creatine kinase (CK), tumor necrosis factor α (TNF-α), high-mobility group box 1 (HMGB-1), malondialdehyde (MDA), and total antioxidant capacity (TAC) before as well as 1, 3, 5, and 7 days after burns were measured. Blood levels of ALT, CRE, CK, TNF-α, HMGB-1, and MDA in INS, EP, and INS+EP groups at different time points were significantly lower, and TAC was significantly higher than that in the control group (C) (P<.01). These parameters in the INS+EP group were significantly lower, and TAC was significantly higher than that in INS and EP groups (P<.01). Blood levels of TNF-α, HMGB-1, and TAC in the INS group at different time points after burns were significantly lower, and MDA was significantly higher than that in the EP group (P<.01). Insulin combined with EP can effectively reduce the inflammatory response, oxidative stress, and main organ dysfunctions in MODS rats after severe burns. The therapeutic effect of insulin combined with EP is superior to single-agent treatment. The insulin anti-inflammatory effect is better than that of pyruvic acid ethyl ester, and the ethyl pyruvate antioxidation effect is better than that of insulin. The insulin can treat inflammation, whereas EP can reduce oxidative stress in MODS rats. Copyright © 2016 Elsevier Inc. All rights reserved.

1. A total of 360 1-d-old male commercial Arbor Acre broiler chickens were randomly assigned to 5 groups (6 replicates of 12 birds each) to evaluate the dietary effects of polysavone (0·5, 1·0 and 1·5 g/kg), a natural extract from alfalfa, and 0·15 g/kg chlortetracycline (CTC) on growth performance, antioxidation and meat quality of broiler chickens. 2. Over the 6-week study, feed intake increased significantly with CTC supplementation and final body weight (BW) was significantly higher for 1·0 g/kg polysavone and 0·15 g/kg CTC treatments. Feed:gain ratio was not significantly affected by the dietary treatments. 3. At 3 weeks of age, serum total superoxide dismutase (T-SOD) activity for all polysavone treatments was significantly higher than controls, liver T-SOD activity in 1·5 g/kg polysavone group was significantly higher than the control and CTC groups, and serum glutathione peroxidase (GSHPx) activity for 1·5 g/kg polysavone and liver GSHPx activity in all polysavone groups were significantly higher than CTC. 4. At 6 weeks of age, serum and liver T-SOD activity in 1·5 g/kg polysavone group and liver GSHPx activity for all polysavone treatments were higher significantly than the control and CTC groups, and serum malondialdehyde (MDA) content for all polysavone treatments was significantly lower than CTC. 5. Breast muscle T-SOD activity and pH value at 6 weeks of age were significantly higher and MDA content was significantly lower in 1·0 and 1·5 g/kg polysavone groups than in the control and CTC groups. Breast muscle shear force was significantly lower in l·5 g/kg polysavone group compared with the control, and drip loss for all polysavone treatments was significantly lower than CTC. 6. It was indicated that polysavone modulates antioxidation and modifies meat quality, but with no adverse effect on performance of broiler chickens, and that CTC can be beneficial to performance but has no beneficial effect on antioxidant function or meat quality.

Background: We compared the effects of adding dexmedetomidine to a 30 ml solution of 0.325% bupivacaine in supraclavicular brachial plexus block. Onset and duration of sensory and motor block along with the duration of analgesia were the primary endpoints. Materials and Methods: Fifty patients posted for upper limb surgeries were enrolled for a prospective, randomized, double-blind, placebo-controlled trial. Patients were divided into two groups, the control group S and the study group SD. In group S (n = 25), 30 ml of 0.325% bupivacaine + 1 ml normal saline; and in group SD (n = 25), 30 ml of 0.325% bupivacaine + 1 ml (100 μg) dexmedetomidine were given for supraclavicular brachial plexus block using the peripheral nerve stimulator. Onset and duration of sensory and motor blocks were assessed along with the duration of analgesia, sedation, and adverse effects, if any. Hemodynamic parameters, like heart rate (HR), systolic arterial blood pressure (SBP), and diastolic arterial blood pressure (DBP) were also monitored. Results: Demographic data and surgical characteristics were comparable in both the groups. The onset times for sensory and motor blocks were significantly shorter in SD than S group (P < 0.001), while the duration of blocks was significantly longer (P < 0.001) in SD group. Except for the initial recordings (at 0, 5, 10, and 15 min), heart rate levels in group SD were significantly lower (P < 0.001). SBP and DBP levels in SD group at 15, 30, 45, 60, 90 and 120 min were significantly lower than in S group (P < 0.001). In fact, when the percentage changes in HR/SBP/DBP were compared from 0-5/0-10/0-15/0-30/0-45/0-60/0-90/0-120 min in SD with S group, they came out to be highly significant (P < 0.001) in group SD. The duration of analgesia (DOA) was significantly longer in SD group than S group (P < 0.001). Except that, bradycardia was observed in one patient in the group SD, no other adverse effects were observed in either of the groups. Conclusion: Dexmedetomidine added as an adjuvant to bupivacaine for supraclavicular brachial plexus block significantly shortens the onset time and prolongs the duration of sensory and motor blocks and duration of analgesia. Patients in group SD were adequately sedated (modified Ramsay Sedation Score, RSS = 2/6 or 3/6) with no adverse effects except bradycardia in one patient of group SD. PMID:24574591

Background: Fatigue is the most common and highly disabling symptom of multiple sclerosis (MS) that has negative effects on employment, the process of socialization, compliance with the disease, and other factors effective on activities of daily living. The usage of complementary and alternative medicine methods in MS patients is higher than in the general population. However, there is no scientific evidence to support their effectiveness. Therefore, this study aimed to compare the effects of reflexology and relaxation on fatigue in women with MS. Materials and Methods: This study is a single-blinded randomized clinical trial that was done on 75 patients with MS who referred to the MS Clinic of Ayatollah Kashani Hospital (Isfahan, Iran). After simple non-random sampling, participants were randomly assigned by minimization method to three groups: Reflexology, relaxation, and control groups (25 patients in each group). In the experimental groups, the interventions foot reflexology and relaxation (Jacobson and Benson) were performed for 4 weeks, twice a week for 40 min in each session, and the control group received care and routine medical treatment as directed by a physician. Data were collected through a questionnaire and the fatigue severity scale before, immediately after, and 2 months after interventions from all three groups. Data analysis was performed by SPSS version 18 using descriptive and inferential statistical methods. Results: Findings obtained from analysis of variance (ANOVA) showed that there was no significant difference in the mean fatigue severity scores in the pre-interventions between the three groups (P > 0.05), but there was significant difference immediately after and 2 months after interventions between the three groups (P < 0.05). Findings obtained from repeated measures (ANOVA) showed that there was significant difference in the mean fatigue severity scores during different times between the three groups (P < 0.05), while this difference was not significant in the control group (P > 0.05). Furthermore, least significant difference post-hoc test revealed that the mean scores of fatigue severity immediately after intervention was lower in the reflexology group than in the other two groups and were lower in the relaxation group than in the control group; 2 months after interventions, the mean scores of fatigue severity were lower in the reflexology group than in the other two groups, but there was no significant difference between the two groups of relaxation and control (P > 0.05). Conclusions: It seems that both interventions were effective in reducing fatigue, but the effects of reflexology on reducing fatigue were more than those of relaxation. Hence, as these two methods are effective and affordable techniques, they can be recommended. PMID:25878696

The observation group were treated with oral administration of Alprazolam, massage of sole, and acupuncture at Zhongwan (CV 12), Guanyuan (CV 4), Qihai (CV 6), etc. on the abdomen as main points; the control group were treated with Alprazolam. Clinical therapeutic effects, and scores for Pittsburgh Sleep Quality Index (PSQI), Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) were assessed before and after treatment in the two groups. The effective rate was 93.75 in the observation group and 88.46% in the control group with no significant difference between the two groups; after treatment, there were significant or very significant differences in scores for various factors in the PSQI, SAS and SDS (P < 0.01, P < 0.05). Abdominal acupuncture as main combined with massage of sole can obviously improve sleeping quality of the patient with insomnia.

To investigate the effects of an aerobic training in subjects with Parkinson's disease (PD) as compared to a medical Chinese exercise (Qigong). randomized controlled trial with a cross over design. PD out-patients referred to a Neurorehabilitation facility for the management of motor disability. 26 PD patients in Hoehn and Yahr stage II to III under stable medication were randomly allocated to either Group AT1+QG2 (receiving 20 aerobic training sessions followed by 20 ''Qigong'' group sessions with 2 month interval between the interventions), or Group QG1+AT2 (performing the same treatments with an inverted sequence). clinical effects of treatment were sought through the Unified Parkinson's Disease Rating Scale (UPDRS), Brown's Disability Scale (B'DS), six-Minute Walking Test (6MWT), Borg scale for breathlessness, Beck Depression Inventory (BDI) and Parkinson's Disease Questionnaire-39 items (PDQ-39). A spirometry test and maximum cardiopulmonary exercise test (CPET) were also performed to determine the pulmonary function, the metabolic and cardio-respiratory requests at rest and under exercise. All measures were taken immediately before and at the completion of each treatment phase. The statistical analysis focusing on the evolution of motor disability and quality of life revealed a significant interaction effect between group and time for the 6MWT (time x group effect: F: 5.4 P=0.002) and the Borg scale (time x group effect: F: 4.2 P=0.009). Post hoc analysis showed a significant increase in 6MWT and a larger decrease in Borg score after aerobic training within each subgroup, whereas no significant changes were observed during Qigong. No significant changes over time were detected through the analysis of UPDRS, B'DS, BDI and PDQ-39 scores. The analysis of cardiorespiratory parameters showed significant interaction effects between group and time for the Double Productpeak (time x group effect: F: 7.7 P=0.0003), the VO(2peak) (time x group effect: F: 4.8 P=0.007), and the VO(2)/kg ratio (time x group effect: F: 4.3 P=0.009), owing to their decrease after aerobic training to an extent that was never observed after Qigong treatment. Aerobic training exerts a significant impact on the ability of moderately disabled PD patients to cope with exercise, although it does not improve their self-sufficiency and quality of life.

The aim of this study is to analyze the effects of combining cone beam computed tomography (CBCT) technology with visual root canal recurrence in the treatment of elderly patients with dental pulp disease. 56 cases of elderly patients with dental pulp disease were contiguously selected, and randomly divided into the control group (70 teeth from 27 patients) and the observation group (77 teeth from the rest 29 patients). We adopted CBCT technology combined with conventional root canal therapy in control group and CBCT technology combined with visual root canal recurrence in observation group to compare the clinical effects. It was found that there was no statistical difference in duration of operation between the two groups (p>0.05). The operation times and the VAS during and after operation of the observation group were significantly less than that of the control group (p<0.05). The duration of follow-up of the two groups was both about 18 months. Successful rates of treatment for 6 months and by the end of follow-up visit in the observation group were both significantly higher than those in the control group (p<0.05). The correct filling rate, good filling rate and fair filling rate in the observation group were significantly higher than those of the control group (p<0.05). CBCT technology combined with visual root canal recurrence can significantly improve the near and long-term treatment effects of elderly patients with dental pulp disease.

The aim of the present study was to assess possible effects on mental and physical well-being and stress-related biological markers of a web-based health promotion tool. A randomized, prospectively controlled study was conducted with before and after measurements, involving 303 employees (187 men and 116 women, age 23-64) from four information technology and two media companies. Half of the participants were offered web-based health promotion and stress management training (intervention) lasting for six months. All other participants constituted the reference group. Different biological markers were measured to detect possible physiological changes. After six months the intervention group had improved statistically significantly compared to the reference group on ratings of ability to manage stress, sleep quality, mental energy, concentration ability and social support. The anabolic hormone dehydroepiandosterone sulphate (DHEA-S) decreased significantly in the reference group as compared to unchanged levels in the intervention group. Neuropeptide Y (NPY) increased significantly in the intervention group compared to the reference group. Chromogranin A (CgA) decreased significantly in the intervention group as compared to the reference group. Tumour necrosis factor alpha (TNFalpha) decreased significantly in the reference group compared to the intervention group. Logistic regression analysis revealed that group (intervention vs. reference) remained a significant factor in five out of nine predictive models. The results indicate that an automatic web-based system might have short-term beneficial physiological and psychological effects and thus might be an opportunity in counteracting some clinically relevant and common stress and health issues of today.

Purpose To compare the results of laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) for myopia using a mixed-effects model. Methods This comparative retrospective study was conducted in 1,127 eyes of 579 patients after LASIK and 270 eyes of 144 patients after PRK who had two or more postoperative follow-ups after 3 months. Uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), manifest refractive spherical equivalent (MRSE), percentage of eyes within ± 0.5 diopters (D) and ± 1.0 D of targeted refraction, and central corneal thickness were compared between PRK and LASIK groups using a mixed-effects model. Results Compared with the LASIK group, UCVA in the PRK group was significantly worse in the initial year but was significantly better after 4 years. The average BSCVA was not significantly different between the LASIK and PRK groups after 4 years. The average gain of BSCVA in the PRK group was significantly larger than that of the LASIK group after 2 years. MRSE in the LASIK and PRK groups showed a gradual myopic shift until 6 years after surgery. After 6 years, MRSE in the PRK group remained stable whereas MRSE in the LASIK group continued a myopic shift. The percentages of eyes within ± 0.5 D or ± 1.0 D in the LASIK group were significantly higher than those in the PRK group at 3 months but were significantly lower than those in the PRK group at 10 years. Conclusions PRK for myopia shows better efficacy than LASIK for myopia after 4 years. PMID:28362808

The previous studies all focus on the effect of probiotics and antibiotics on infection after liver transplantation. Here, we focus on the effect of gut microbiota alteration caused by probiotics and antibiotics on hepatic damage after allograft liver transplantation. Brown-Norway rats received saline, probiotics, or antibiotics via daily gavage for 3 weeks. Orthotopic liver transplantation (OLT) was carried out after 1 week of gavage. Alteration of the intestinal microbiota, liver function and histopathology, serum and liver cytokines, and T cells in peripheral blood and Peyer's patch were evaluated. Distinct segregation of fecal bacterial diversity was observed in the probiotic group and antibiotic group when compared with the allograft group. As for diversity of intestinal mucosal microbiota and pathology of intestine at 2 weeks after OLT, antibiotics and probiotics had a significant effect on ileum and colon. The population of Lactobacillus and Bifidobacterium in the probiotic group was significantly greater than the antibiotic group and the allograft group. The liver injury was significantly reduced in the antibiotic group and the probiotic group compared with the allograft group. The CD4/CD8 and Treg cells in Peyer's patch were decreased in the antibiotic group. The intestinal Treg cell and serum and liver TGF-β were increased markedly while CD4/CD8 ratio was significantly decreased in the probiotic group. It suggested that probiotics mediate their beneficial effects through increase of Treg cells and TGF-β and deduction of CD4/CD8 in rats with acute rejection (AR) after OLT.

To evaluate the role of low molecular chitosan containing sepia ink (LMCS) in ethanol-induced (5 ml/kg) gastric ulcer in rats. Animals were divided into four groups (n = 12): normal group (Normal), negative control group (Con), experiment group (LMCS) and positive control Omeprazole group (OMZ). Gastric empty rate was detected in the first 7 days. Rats were sacrificed at 7, 14 and 21 day for histology and ELISA detections. Gastric empty was no significant differences among the groups (P > 0.05). Histological observation showed gastric mucosal LMCS treated had better healing effect. Hydroxyproline (Hyp) was significantly increased from 7 day (P < 0.05). LMCS significantly inhibited malondialdehyde (MDA) generation for lipid peroxidation from 7 day (P < 0.05). LMCS significantly promoted the activity of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) at the earlier stage (P < 0.05). OMZ had the similar effects above. As for myeloperoxidase (MPO), LMCS significantly decreased and restored it to normal levels from 7 day (P < 0.05), it is earlier than OMZ which is from 14 day. LMCS can improve gastric mucosa tissue repair, exert significant influences on oxidative and antioxidant enzyme activities and neutrophil infiltration.

This study aimed to evaluate the effects of barley flour, crude cinnamon, and their combination on blood glucose, serum insulin, serum lipid profile, and serum adipose tissue hormones in streptozotocin-induced diabetic rats. Male Wistar rats (n=35) were divided into five groups: nondiabetic, diabetic, diabetic group fed 5% cinnamon, diabetic group fed 30% barley, and diabetic group fed 5% cinnamon and 30% barley. Fasting blood glucose, insulin, lipid profile, adiponectin, and leptin were measured after 8 weeks. Blood glucose significantly decreased in all treated diabetic rats compared with the diabetic group. Serum insulin and high-density lipoprotein significantly increased, while cholesterol, triglycerides, and low-density lipoprotein were significantly decreased after 8 weeks. Adiponectin significantly increased, while leptin significantly decreased with administration of either cinnamon, barley, or their combination. No significant differences were observed among the three treated groups on all parameters. A cinnamon and barley combination caused obvious improvement in insulin-positive cells of pancreatic tissue. In conclusion, consuming diets containing either cinnamon, barley, or their combination regulates blood glucose, lipid profile, and adipose tissue hormones in type 2 diabetic rats. The most effective treatment was the cinnamon and barley combination.

The effects of MS-222 and clove oil on blood biochemical parameters of juvenile Siberian sturgeon (Acipenser baerii) were studied. MS-222 caused higher glucose (GLU) concentrations in anaesthetic test groups than for the control group. Triglyceride (TGL) concentrations of fish in the 140 and 160mgL-1 groups were also significantly higher than those of other groups. Alanine aminotransferase (ALT) activity in the 140mgL-1 group was significantly higher than the level in 80, 100 and 120mgL-1 groups. Aspartate aminotransferase (AST) activity in the 140mgL-1 group was significantly higher than those in the 100 and 120mgL-1 groups. Levels of total protein (TP), cholesterol (CHOL) and alkaline phosphatase (ALP) in anaesthetic test groups were not significantly influenced by MS-222. Clove oil did not have significant effects on levels of GLU, TP, CHOL, ALT and ALP. TGL concentration of fish exposed to 180mgL-1 clove oil was significantly higher than those of the rest anaesthetic groups. AST activities of fish exposed to 120, 150 and 180mgL-1 were significantly higher than those of 60 and 90mgL-1. Overall, TGL and AST could be potentially used as indicators of anaesthetic stress for juvenile Siberian sturgeon. Based on blood biochemical parameters, the appropriate anaesthetic concentrations of MS-222 and clove oil were 80-120mgL-1 and 60-90mgL-1, respectively. Clove oil was a promising alternative to MS-222. ?? 2011 Blackwell Verlag, Berlin.

To study the impact on seizure frequency and epileptiform discharges of children with epilepsy from topiramate (TPM) and phenobarbital (PB). Two hundred cases children with epilepsy from August 2010 to August 2013 in our hospital were sampled and randomly divided into two groups. The observation group was treated with TPM while the control group with PB, and then comparing seizure frequency, efficiency, and adverse reactions of two groups. The reduced number of partial seizures, generalized seizures, and total seizures in the observation group were significantly higher than those in the control group, and the rate of cure, markedly effective and total efficiency in observation group were significantly higher than those in the control group. However, the adverse reactions in observation group were significantly lower than those in the control group. Thus, differences were statistically significant (p<0.05). Compared with PB, TPM showed a better effect on epilepsy treatment with less adverse reactions which were worthy of clinical recommendation.

OBJECTIVES: To evaluate the effects of Urtica dioica on hepatic ischemia‐reperfusion injury. METHODS: Thirty adult male Wistar albino rats were divided into three groups: sham group (group 1), control group (group 2), and Urtica dioica group (group 3). All the rats were exposed to hepatic ischemia for 60 min, followed by 60 min of reperfusion. In group 2, a total of 2 ml/kg 0.9% saline solution was given intraperitoneally. In group 3, a total of 2 ml/kg Urtica dioica was given intraperitoneally. At the end of the procedure, liver tissue and blood samples were taken from all rats. Serum aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, ceruloplasmin, catalase, paraoxonase, arylesterase, and lipid hydroperoxide levels were measured. Liver tissue histopathologies were also evaluated by light microscopy. RESULTS: Serum aspartate aminotransferase, alanine aminotransferase and lactate dehydrogenase levels were significantly higher in group 2 than in group 1, and significantly lower in group 3 than in group 2. Also, group 2 had higher serum lipid hydroperoxides and ceruloplasmin levels but lower catalase, paraoxonase, and arylesterase levels than group 1. In group 3, serum lipid hydroperoxides and ceruloplasmin levels were significantly lower, and catalase, paraoxonase, and arylesterase levels were higher than those in group 2. Histopathological examination showed that liver tissue damage was significantly decreased in group 3 compared with group 2. CONCLUSIONS: Urtica dioica has a protective effect on the liver in hepatic ischemia‐reperfusion‐injured rats. PMID:21340227

There have been calls to test the potential benefits of different forms of physical activity (PA) to executive function, particularly in authentic settings. Hence, the purpose of this study was to investigate the effect of an acute dance session within an existing physical education class on students' selective attention. The study employed a pre/posttest quasi-experimental design with a comparison group in one Aotearoa, New Zealand, primary school. Participants were 192 students (comparison group = 104 students) in Years 5 and 6. The intervention group participated in a dance-based physical education lesson while the comparison group continued their regular classroom work. PA during the physical education lesson was monitored using accelerometers. Selective attention was assessed at pretest and after the comparison/physical education sessions with the d2 Test of Attention. 2 × 2 ANOVA results suggested a significant time effect for all three measures, no significant group effects for any measures, and significant time by group interactions for TN and CP but not for E%. The intervention group improved significantly more than the comparison group for TN and CP. This study's findings suggest that existing school opportunities focused on cognitively engaging PA, such as dance, can improve aspects of students' selective attention. PMID:29662903

The aim of this study was to examine the potential effects of valproate (VPA) and oxcarbazepine (OXC) on testicular development in rats. Forty-two Wistar rats were randomly divided into three groups of 14 rats each. Each group received the following via gavage over 90 days: group 1, tap water (control group); group 2, VPA (300mg/kg/day); group 3, OXC (100mg/kg/day). After sacrifice, body, testicular and epididymidis weights were measured. Testes were sampled, fixed and processed, and quantitative morphometric analysis of Sertoli cells, spermatocytes and spermatids was performed in stages II, V and XII by histopathological examination. Immunohistochemical staining was performed to transform growth factor beta 1 (TGF-β1) and p53, and the apoptotic index was assessed using the TUNEL method. Testis and relative testis weights were significantly lower in the VPA group compared to the control group (p<0.05). Spermatogonia, pachytene spermatocyte and round spermatocyte numbers decreased in all stages in both the VPA and OXC groups compared to the control group, though this was not statistically significant (p>0.05). Apoptotic cell counts and p53 immunoreaction were significantly high and TGF-β1 expression was significantly lower in the VPA group compared to that of the control group (p<0.05). In the OXC group, p53 immunoreaction and TGF-β1 expression decreased compared to the control group, but this difference did not attain statistical significance (p>0.05). Our results show that VPA treatment from prepuberty to adulthood significantly negatively affects spermatogenesis, not only by reducing testicular weight, but also by increasing apoptotic death and p53 and decreasing TGF-β1 activation. OXC has a minimal side effect on testicular development. Copyright © 2010 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

We examined the combined effects of elcatonin (ECT) and alendronate (ALN) on bone mass, architecture, and strength in ovariectomized (OVX) rats. Fifty female Sprague Dawley rats, aged 13 weeks, were divided into Sham, OVX, OVX+ECT, OVX+ALN, and OVX+ECT+ALN groups (n = 10). Immediately after ovariectomy, ECT was administered at a dose of 15 units (U)/kg three times a week, and ALN was administered daily at a dose of 2.0 microg/kg, subcutaneously for 12 weeks. The three-dimensional architecture of the bone in the distal femoral metaphysis was analyzed using a microfocus X-ray computed tomography system (microCT), and bone strength was measured using a material-testing machine. Trabecular bone volume (BV/TV) and number (Tb.N) were significantly greater in the OVX+ECT and OVX+ALN groups than in the OVX group. In the OVX+ECT+ALN group, BV/TV and Tb.N were significantly greater when compared with those in the OVX+ECT and OVX+ALN groups. Trabecular thickness (Tb.Th) was significantly greater in the OVX+ECT+ALN group than in the OVX+ALN group. With regard to bone strength, the compression strength in the femoral metaphysis was significantly lower in the OVX group than in the Sham group. The reduction of compression strength was slightly lower in the OVX+ECT and OVX+ALN groups. In the OVX+ECT+ALN group, the compression strength in the femoral metaphysis significantly increased when compared with the OVX and OVX+ECT groups. These results suggest that the combined treatment of ECT and ALN does not alter the individual effects of each drug and that it exerts an additive effect on trabecular architecture and bone strength in OVX rats.

We evaluated the efficacy of N-acetylcysteine for testicular damage induced by undescended testes in rats. Flutamide was injected in the abdomen of pregnant rats daily from days 14 to 20 of gestation. Male offspring with cryptorchidism were randomly divided into 2 groups. Healthy male rats without undescended testes comprised the control group (group 1). Group 2 (undescended testes without N-acetylcysteine) received no treatment. Group 3 (undescended testes plus N-acetylcysteine) received intraperitoneal N-acetylcysteine daily. At 70 days after experiment initiation the testes were removed for histopathological and biochemical analysis. Mean malonyl dialdehyde values were lowest in group 1 and highest in group 2. In group 3 malonyl dialdehyde levels were significantly lower than in group 2 (p <0.001). Conversely, mean glutathione peroxidase was highest in group 1 and lowest in group 2. Glutathione peroxidase levels in group 3 were significantly higher than in group 2 (p <0.001). Histopathological differences between groups 1 and 3 in the modified Johnsen score were not significant (p = 0.041). However, the differences between these groups and group 2 were significant (p <0.001). The median apoptotic cell count did not differ between groups 1 and 3 but it was significantly higher in group 2 than in the other groups (p = 0.03 and <0.001, respectively). N-acetylcysteine may alleviate undescended testis induced damage to testes through its antioxidant effects. The underlying mechanism of these effects merits further investigation. Long-term studies are also needed as well as comparative animal and human studies. Copyright © 2014 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

Examined the effects of four treatment conditions on the modification of Irrational Ideas and test anxiety in female nursing students. The treatments were Rational Stage Directed Hypnotherapy, a cognitive behavioral approach that utilized hypnosis and vivid-emotive-imagery, a hypnosis-only treatment, a placebo condition, and a no-treatment control. The 48 Ss were assigned randomly to one of these treatment groups, which met for 1 hour per week for 6 consecutive weeks with in-vivo homework assignments also utilized. Statistically significant treatment effects on cognitive, affective, behavioral, and physiological measures were noted for both the RSDH and hypnosis group at the posttest and at a 2-month follow-up. Post-hoc analyses revealed the RSDH treatment group to be significantly more effective than the hypnosis only group on both the post- and follow-up tests. The placebo and control groups showed no significant effects either at post-treatment or at follow-up.

This study determines the effect of simulation with team-based learning (TBL) on newborn nursing care. This randomized controlled trial included 74 nursing students from one university located in Seoul, South Korea. Participants were categorized into two groups according to educational modality: one group involved both simulation and TBL, and the other involved simulation alone. Learning attitudes, academic achievement, and simulation performance were examined to assess effectiveness. The mean difference in learning attitudes between the two groups was non-significant. Low academic achievement differed significantly between the two groups (t = 3.445, P = 0.002). There was no significant difference in mean scores for simulation performance between the two groups. In this study, simulation with TBL was effective in improving learning outcomes. In current nursing education, various learning methods are employed within complex nursing situations and require flexibility and problem-solving approaches. © 2015 Wiley Publishing Asia Pty Ltd.

The purpose of this study was to compare the effects of exercise therapy, alternating cold and hot (ACH) therapy and low intensity laser (LIL) therapy in patients with chronic lumbar muscle strain (CLMS). Thirty-two patients were randomly allocated to four groups: exercise group, ACH group, LIL group, and combination group of exercise, ACH and LIL, eight in each group. Sixteen treatments were given over the course of 4 weeks. Lumbar muscle endurance, flexion and lateral flexion measures, visual analogue scale (VAS) and lumbar disability questionnaire (LDQ) were used in the clinical and functional evaluations before, immediately after, and 4 weeks after treatment. It was found that the values of endurance, VAS and LDQ in all groups were significantly improved from before to after treatment (P < 0.01). The combination group showed significantly larger reduction on pain level and functional disability than the other groups immediately and 4 weeks after treatment (P < 0.01). Pain level reduced significantly more in the ACH group than in the exercise group or the LIL group immediately and 4 weeks after treatment (P < 0.05). Lumbar muscle endurance and spinal ranges of motion in all groups were improved after treatment but there was no significant difference between any therapy groups. In conclusion, exercise therapy, ACH therapy and LIL therapy were effective in the treatment of CLMS. ACH therapy was more effective than exercise therapy or LIL therapy. The combination therapy of exercise, ACH and LIL had still better rehabilitative effects on CLMS.

We propose that pheniramine maleate, an antihistaminic, may suppress this cough. We aim to observe the effect of pheniramine on fentanyl-induced cough during anesthesia induction. This is a double-blinded, prospective, three-arm parallel, randomized clinical trial of 120 patients with ASA (American Society of Anesthesiologists) physical status III and IV who aged ≥18 and scheduled for elective open heart surgery during general anesthesia. Patients were randomly assigned to three groups of 40 patients, using computer-generated random numbers: placebo group, pheniramine group, and lidocaine group. Cough incidence differed significantly between groups. In the placebo group, 37.5% of patients had cough, whereas the frequency was significantly decreased in pheniramine group (5%) and lidocaine group (15%) (Fischer exact test, p=0.0007 and p=0.0188, respectively). There was no significant change in cough incidence between pheniramine group (5%) and lidocaine group (15%) (Fischer exact test, p=0.4325). Cough severity did also change between groups. Post Hoc tests with Bonferroni showed that mean cough severity in placebo differed significantly than that of pheniramine group and lidocaine group (p<0.0001 and p=0.009, respectively). There was no significant change in cough severity between pheniramine group and lidocaine group (p=0.856). Intravenous pheniramine is as effective as lidocaine in preventing fentayl-induced cough. Our results emphasize that pheniramine is a convenient drug to decrease this cough. Copyright © 2015 Sociedade Brasileira de Anestesiologia. Published by Elsevier Editora Ltda. All rights reserved.

To evaluate the effect of combination of hydroxyapatite (HA) and hydrogen peroxide (HP) on color, microhardness and morphology of human tooth enamel. Forty-eight human dental blocks were obtained from 12 pairs of premolars and were randomly divided into four groups. Group DW was treated with distilled water, group HP with 30% HP, group HA+DW with HA mixed with distilled water and group HA+HP with HA mixed with 30% HP. Baseline and final color measurements and microhardness test were carried out before and after bleaching experiments. Two specimens from each group were selected for morphological investigation after final tests. The DeltaE of group HP and HA+HP were significantly higher than those of group DW (p=0.000 and p=0.000) and group HA+DW (p=0.000 and p=0.000). The percentage microhardness loss of group HA+HP was significantly lower than that of group HP (p=0.047), but significantly higher than those of group DW (p=0.000) and group HA+DW (p=0.000). The obvious variation of morphology was only observed on enamel surfaces in group HP. This study suggested that combination of HA and HP was effective in tooth whitening. HA could significantly reduce the microhardness loss of enamel caused by 30% HP and keep enamel surface morphology almost unchanged.

Radiation proctitis (RP) is inflammation and damage to the rectum, manifested secondary to ionizing radiation utilized for treatment. In this study, we evaluated the anti-inflammatory therapeutical and protective effects of ruscogenin in a model of acute RP. Thirty-two Sprague-Dawley rats were divided into 4 groups (n = 8) as sham, control, treatment, and prophylaxis groups. Prophylaxis group and treatment group were dosed ruscogenin by oral gavage for 14 days pre- and postradiation. At the end of the 28th day, all subjects were sacrificed. Histopathological analysis showed a significant increase in cryptitis abscess, cryptitis and reactive atypia, and depth of lymphocytic infiltration of the control group, compared to the other groups (P < 0.05), while treatment and prophylaxis groups showed significant decreases (P < 0.05). Immunohistochemical analysis indicated that immunoreactivity were significantly higher in control group (P < 0.05, P < 0.001, and P < 0.01, respectively), but vice versa for treatment and prophylaxis groups. There was not any significant difference for fibroblast growth factor 2 immunoreactivity. The epithelium of control rectums indicated an increase in TNF-α immunoreactivity while other groups had significant decrease (P < 0.01). Electron microscopical findings were parallel to light microscopy. In this study, ruscogenin was observed to be effective on prophylaxis or treatment of acute RP. Although there are various reports on the treatment of the rectum damaged by acute RP in the literature, this could be the first study since there is no research indicating the ultrastructural effect of ruscogenin.

To investigate the efficacy of an aqueous extract from date seeds on diabetic rats. The study was performed in the Department of Anatomy, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia between November 2008 and December 2009. Eighty adult albino rats were divided into 4 groups. Group 1 was used as healthy control. Group 2 was given daily ingestions of 10 ml of the date seed extract. Animals of groups 3 and 4 were made diabetic by injection of streptozotocin. Diabetic rats of group 3 received daily subcutaneous injections of 3 IU/day of insulin for 8 weeks while group 4 received ingestions of 10 ml of extract in addition to insulin. Fasting blood glucose levels were measured once weekly. Glycosylated hemoglobin (HbA1c) was also estimated. There is a significant change in the mean blood glucose levels between group 3 and group 4 from week 2. The mean blood glucose levels of group 4, every 2 consecutive weeks, showed a significant decrease until week 6. The HbA1c was significantly lower in group 4 compared to group 3. The hypoglycemic effect of date seed extract combined with insulin, decreases the blood glucose level significantly toward normal when compared to the effect of insulin administered as a single drug for treatment of diabetes.

To study the efficacy of yoga on Guna (yogic personality measure) and general health in normal adults. Of the 1228 persons who attended introductory lectures, 226 subjects aged 18-71 years, of both sexes, who satisfied the inclusion and exclusion criteria and who consented to participate in the study were randomly allocated into two groups. The Yoga(Y) group practised an integrated yoga module that included asanas, pranayama, meditation, notional correction and devotional sessions. The control group practised mild to moderate physical exercises (PE). Both groups had supervised practice sessions (by trained experts) for one hour daily, six days a week for eight weeks. Guna (yogic personality) was assessed before and after eight weeks using the self-administered Vedic Personality Inventory (VPI) which assesses Sattva (gentle and controlled), Rajas (violent and uncontrolled) and Tamas (dull and uncontrolled). The general health status (total health), which includes four domains namely somatic symptoms (SS), anxiety and insomnia (AI), social dysfunction (SF) and severe depression (SP), was assessed using a General Health Questionnaire (GHQ). Baseline scores for all the domains for both the groups did not differ significantly (P > 0.05, independent samples t test). Sattva showed a significant difference within the groups and the effect size was more in the Y than in the PE group. Rajas showed a significant decrease within and between the groups with a higher effect size in the PE group. Tamas showed significant reduction within the PE group only. The GHQ revealed that there was significant decrease in SS, AI, SF and SP in both Y and PE groups (Wilcoxcon Singed Rank t test). SS showed a significant difference between the groups (Mann Whitney U Test). There was an improvement in Sattva in both the Yoga and control groups with a trend of higher effect size in Yoga; Rajas reduced in both but significantly better in PE than in Yoga and Tamas reduced in PE. The general health status improved in both the Yoga and control groups.

More than a third of the approximately 10 million women with histories of interpersonal violence in the United States develop posttraumatic stress disorder (PTSD). Currently available treatments for this population have a high rate of incomplete response, in part because problems in affect and impulse regulation are major obstacles to resolving PTSD. This study explored the efficacy of yoga to increase affect tolerance and to decrease PTSD symptomatology. Sixty-four women with chronic, treatment-resistant PTSD were randomly assigned to either trauma-informed yoga or supportive women's health education, each as a weekly 1-hour class for 10 weeks. Assessments were conducted at pretreatment, midtreatment, and posttreatment and included measures of DSM-IV PTSD, affect regulation, and depression. The study ran from 2008 through 2011. The primary outcome measure was the Clinician-Administered PTSD Scale (CAPS). At the end of the study, 16 of 31 participants (52%) in the yoga group no longer met criteria for PTSD compared to 6 of 29 (21%) in the control group (n = 60, χ²₁ = 6.17, P = .013). Both groups exhibited significant decreases on the CAPS, with the decrease falling in the large effect size range for the yoga group (d = 1.07) and the medium to large effect size decrease for the control group (d = 0.66). Both the yoga (b = -9.21, t = -2.34, P = .02, d = -0.37) and control (b = -22.12, t = -3.39, P = .001, d = -0.54) groups exhibited significant decreases from pretreatment to the midtreatment assessment. However, a significant group × quadratic trend interaction (d = -0.34) showed that the pattern of change in Davidson Trauma Scale significantly differed across groups. The yoga group exhibited a significant medium effect size linear (d = -0.52) trend. In contrast, the control group exhibited only a significant medium effect size quadratic trend (d = 0.46) but did not exhibit a significant linear trend (d = -0.29). Thus, both groups exhibited significant decreases in PTSD symptoms during the first half of treatment, but these improvements were maintained in the yoga group, while the control group relapsed after its initial improvement. Yoga significantly reduced PTSD symptomatology, with effect sizes comparable to well-researched psychotherapeutic and psychopharmacologic approaches. Yoga may improve the functioning of traumatized individuals by helping them to tolerate physical and sensory experiences associated with fear and helplessness and to increase emotional awareness and affect tolerance.

Abstract Background The aim of this study was to investigate the efficacy and safety of blonanserin treatment after switching from other atypical antipsychotics in schizophrenic inpatients who showed inadequate efficacy and poor tolerability. Methods A total of 63 schizophrenic inpatients (inadequate response group=45 and poor tolerability group=18) were included in this study. They were already treated with atypical antipsychotics except blonanserin and not favored due to inadequate responses or intolerable adverse effects. Blonanserin was administered during 12 weeks after switching from their previous antispsychotics. Treatment response was evaluated with Brief Psychiatric Rating Scale (BPRS) and CGI-S, and safety profile were measured with Abnormal Involuntary Movement Scale (AIMS), Simpson-Angus Extrapyramidal Side effects Scale (SAR)S and Barnes Akathisia Rating Scale (BARS). Drug Attitude Inventory (DAI-10) and Subjective Well-being Under Neuroleptic Treatment (SWN) were used for subjective estimates. Assessments were done at baseline, 1, 2, 4, 8 and 12 weeks after blonanserin treatment. Repeated measures of ANOVA were done to analyze the group (inadequate vs. intolerable group) and time effects. Results CGI and BPRS were showed significant treatment responses after switching to Blonaserin. Time effects were significant at 2, 4, 8, 12 weeks after switching and group by time effect were also significant at that time. Mean changes of AIMS, SARS and BARS scores were not significant throughout test trial. Although SWN was significantly improved after switching to Blonaserin, it was not found significant group by time effect. Discussion The results suggest that blonanserin may be effective and well tolerable in schizophrenic patients who showed inadequate treatment response or poor tolerability.

Evaluation of Long-Term Cochlear Implant Use in Subjects With Acquired Unilateral Profound Hearing Loss: Focus on Binaural Auditory Outcomes.

Mertens, Griet; De Bodt, Marc; Van de Heyning, Paul

Cochlear implantation (CI) in subjects with unilateral profound sensorineural hearing loss was investigated. The authors of the present study demonstrated the binaural auditory outcomes in a 12- and 36-month prospective cohort outcome study. The present study aimed to do a long-term (LT) evaluation of the auditory outcomes in an analogous study group. LT evaluation was derived from 12 single-sided deaf (SSD) CI recipients and from 11 CI recipients with asymmetric hearing loss (AHL). A structured interview was conducted with each subjects. Speech perception in noise and sound localization were assessed in a CIOFF and in a CION condition. Four binaural effects were calculated: summation effect (S0N0), squelch effect (S0NCI), combined head shadow effect (SCIN0), and spatial release from masking (SRM). At the LT evaluation, the contribution of a CI or a bone conduction device on speech perception in noise was investigated in two challenging spatial configurations in the SSD group. All (23/23) subjects wore their CI 7 days a week at LT follow-up evaluation, which ranged from 3 to 10 years after implantation. In the SSD group, a significant combined head shadow effect of 3.17 dB and an SRM benefit of 4.33 dB were found. In the AHL group, on the other hand, the summation effect (2.00 dB), the squelch effect (2.67 dB), the combined head shadow effect (3.67 dB), and SRM benefit (2.00 dB) were significant at LT testing. In both the spatial challenging configurations, the speech in noise results was significantly worse in the condition with the bone conduction device compared with the unaided condition. No negative effect was found for the CION condition. A significant benefit in the CION condition was found for sound localization compared with the CIOFF condition in the SSD group and in the AHL group. All subjects wore their CI 7 days a week at LT follow-up evaluation. The presence of binaural effects has been demonstrated with speech in noise testing, sound localization, and subjective evaluation. In the AHL group, all investigated binaural effects were found to be significant. In the SSD group on the other hand, only SRM and the head shadow, the two most robust binaural effects, were significantly present. However, it took 12M before the SSD and the AHL subjects significantly benefit from the head shadow effect. These reported results could guide counseling of future CI candidates with SSD and AHL in general.

We aimed to evaluate the effect of chronic hypergravity in a mouse model of allergic asthma and rhinitis. Forty BALB/c mice were divided as: group A (n = 10, control) sensitized and challenged with saline, group B (n = 10, asthma) challenged by intraperitoneal and intranasal ovalbumin (OVA) to induce allergic asthma and rhinitis, and groups C (n = 10, asthma/rotatory control) and D (n = 10, asthma/hypergravity) exposed to 4 weeks of rotation with normogravity (1G) or hypergravity (5G) during induction of asthma/rhinitis. Group D showed significantly decreased eosinophils, neutrophils, and lymphocytes in their BAL fluid compared with groups B and C (p < 0.05). In real-time polymerase chain reaction using lung homogenate, the expression of IL-1β was significantly upregulated (p < 0.001) and IL-4 and IL-10 significantly downregulated (p < 0.05) in group D. Infiltration of inflammatory cells into lung parenchyma and turbinate, and the thickness of respiratory epithelium was significantly reduced in group D (p < 0.05). The expression of Bcl-2 and heme oxygenase-1 were significantly downregulated, Bax and extracellular dismutase significantly upregulated in Group D. Therefore, chronic hypergravity could have a hormetic effect for allergic asthma and rhinitis via regulation of genes involved in antioxidative and proapoptotic pathways. It is possible that we could use hypergravity machinery for treating allergic respiratory disorders.

To investigate the effects of partial and full correction of refractive errors on sensorial and motor outcomes in children with refractive accommodative esotropia (RAE). The records of pediatric cases with full RAE were reviewed; their first and last sensorial and motor findings were evaluated in two groups, classified as partial (Group 1) and full correction (Group 2) of refractive errors. The mean age at first admission was 5.84 ± 3.62 years in Group 1 (n = 35) and 6.35 ± 3.26 years in Group 2 (n = 46) (p = 0.335). Mean change in best corrected visual acuity (BCVA) was 0.24 ± 0.17 logarithm of the minimum angle of resolution (logMAR) in Group 1 and 0.13 ± 0.16 logMAR in Group 2 (p = 0.001). Duration of deviation, baseline refraction and amount of reduced refraction showed significant effects on change in BCVA (p < 0.05). Significant correlation was determined between binocular vision (BOV), duration of deviation and uncorrected baseline amount of deviation (p < 0.05). The baseline BOV rates were significantly high in fully corrected Group 2, and also were found to have increased in Group 1 (p < 0.05). Change in refraction was - 0.09 ± 1.08 and + 0.35 ± 0.76 diopters in Groups 1 and 2, respectively (p = 0.005). Duration of deviation, baseline refraction and the amount of reduced refraction had significant effects on change in refraction (p < 0.05). Change in deviation without refractive correction was - 0.74 ± 7.22 prism diopters in Group 1 and - 3.24 ± 10.41 prism diopters in Group 2 (p = 0.472). Duration of follow-up and uncorrected baseline deviation showed significant effects on change in deviation (p < 0.05). Although the BOV rates and BCVA were initially high in fully corrected patients, they finally improved significantly in both the fully and partially corrected patients. Full hypermetropic correction may also cause an increase in the refractive error with a possible negative effect on emmetropization. The negative effect of the duration of deviation on BOV and BCVA demonstrates the significance of early treatment in RAE cases.

Mobile applications can be used as effective simulations for nursing education. However, little is known regarding the effects of mobile application-mediated training on nursing. The aim of this study was to determine the effectiveness of mobile applications by comparing the effectiveness of a high-fidelity human patient simulator to that of a mobile application on student learning. Following lectures on the lungs and the heart, twenty-two students were separated into two groups to perform a simulation exercise. Then, the students' education effects were evaluated based on their knowledge of lung and heart assessments, their clinical assessment skill, and satisfaction with their education. After four weeks, the mobile application group maintained their knowledge, whereas the high-fidelity human patient simulator group exhibited significantly decreased knowledge of the lung assessment. Knowledge of the heart assessment was significantly increased in both groups. There was no significant difference in clinical assessment skill or educational satisfaction between the groups. We found that mobile applications provide educational tools similarly effective to a high-fidelity human patient simulator to maintain memory and to teach cardiopulmonary assessment skills.

Arresting at a certain stage of development like the two-cell stage could be one of the causes of infertility. The aim of this study is to evaluate the effects of ethanol and strontium on growth and development of mice embryos arrested at the two-cell stage. In this experimental study, female mice were coupled with a male following superovulation. Positive vaginal plug mice were sacrificed 48 hours after human chorionic gonadotropin (hCG) injection. Two-cell embryos were transferred to M16 medium and divided to four groups. The first control group was incubated without any exposure to low temperatures. Groups 2, 3 and 4 were exposed to 4°C for 24 hours. The second control group was incubated immediately, while the third and fourth groups were exposed to 10 mM strontium for five minutes and 0.1% ethanol for a further five minutes. Growth rate and developmental parameters of embryos were analyzed by one- way ANOVA. The significant difference between the groups was determined by Post Hoc. The data shows that developmental rate is decreased significantly by 4°C exposure. The mean percentage of degenerated embryo was significantly different between groups but the mean cleavage rate was not significantly different. The mean percent of morula, blastocyst and hatched blastocyst formation were significantly different between groups during a 120 hours study post hCG injection. The effect of strontium and ethanol on arrested two-cell embryos had no significant effect on the mean percentage of morula, but ethanol treatment significantly increased the percentage of blastocyst and hatched blastocyst formation compared to strontium.

This study was to investigate the relationship of dose-effect and time-effect of Alginate-Polylysine-Alginate (APA) microencapsulated bovine chromaffin cells on the treatment of pain model rats. Using a rat model of painful peripheral neuropathy, the antinociceptive effects of APA microencapsulated bovine cells transplanted into the subarachnoid space was evaluated by cold allodynia test and hot hyperalgesia test. Compared with control group, the withdrawal difference with cell number 50 thousands groups, 100 thousands groups and 200 thousands groups was reduced (P < 0.05), and the difference decreased with the cells increases, indicating a significant analgesic effect. There was no significant difference between 400 thousands groups and 200 thousands groups. This analgesic effect maintained longer than 12 weeks. There was a positive correlation between the analgesic effect and the quantity of APA microencapsulated bovine chromaffin cells which were transplanted to treat pain model rats, and the effective antinociception remained longer than 12 weeks.

The present study examined both quantitative and qualitative hypnotizability differences among four psychiatric patient groups (dissociative disorder (n = 17), schizophrenic (n = 13), mood disorder (n = 14), and anxiety disorder (n = 14) patients), and normals (college students (n = 63)). Dissociative disorder patients earned significantly higher corrected total scores on the Stanford Hypnotic Susceptibility Scale, Form C (mean = 7.94), than all other groups. Likewise, dissociative disorder patients initially recalled significantly fewer items when the posthypnotic amnesia suggestion was in effect (mean = .41) and reversed significantly more items when the suggestion was canceled (mean = 3.82) than all other groups. In contrast, schizophrenic patients recalled significantly fewer items when the amnesia suggestion was in effect (mean = 1.85) and reversed significantly fewer items when it was canceled (mean = .77) than the remaining groups. This qualitative difference between schizophrenic patients and the other groups on the suggested posthypnotic amnesia item was observed even though there were no significant quantitative differences between groups in overall hypnotic responsivity.

The aim of the study was to confirm the efficiency and safety of the fractional CO2 laser in skin renewal and to check the possibility of having a synergistic effect in patients who besides carbon dioxide laser are treated with PRP (platelet-rich plasma) too. The first group (Examined Group 1 or EG1) included 107 patients treated with fractional CO2 laser (Lutronic eCO2) as mono-therapy. The second group (Control Group or CG) covered 100 patients treated with neither laser nor plasma in the same period but subjected to local therapy with drugs or other physio-procedures under the existing protocols for treatment of certain diseases. The third group (Examined Group 2 or EG2) treated 25 patients with combined therapy of CO2 laser and PRP in the treatment of facial rejuvenation or treatment of acne scars. Patient's satisfaction, in general, is significantly greater in both examined groups (EG1 and EG2) (p < 0.001). It was found the significant difference between control and examined group from the treatment in acne scar (Fisher exact two tailed p < 0.001). Patients satisfaction with the treatment effect in rejuvenation of the skin is significant (χ2 = 39.41; df = 4; p < 0.001). But, patients satisfaction from the treatment with HPV on the skin was significantly lower in examined group (treated with laser), p = 0.0002. Multifunctional fractional carbon dioxide laser used in treatment of patients with acne and pigmentation from acne, as well as in the treatment of scars from different backgrounds, is an effective and safe method that causes statistically significant better effect of the treatment, greater patients' satisfaction, minimal side effects and statistically better response to the therapy, according to assessments by the patient and the therapist.

Due to the special training conditions and lifestyle athletes require an antioxidant system that is more efficient than others. To keep this system optimal, many of them use antioxidant supplements. This study aimed to investigate the effects of vitamins C and E supplementation on muscle damage, performance, and body composition in athlete women. The study was a 4-week randomized, double-blind clinical trial conducted on 64 trained female athletes recruited in Isfahan sports club. They were randomly assigned to one of the following four groups; A: vitamin C (250 mg/day), B: vitamin E (400 IU), C: vitamin C + vitamin E and control (placebo). Harvard Step Test was used to measure maximal oxygen consumption for performance, body composition, and damage marker (myoglobin) were measured before and after the intervention. Comparing the result of the test in performance of sport, there was no significant difference between groups in VO2 max. Also, vitamin supplements had no significant effect on subcutaneous fat between the groups, however, in the intergroup comparison, were significantly increased in group control (P = 0.03). But, there were no significant differences, change in myoglobin between the groups. There was a significant increase in group A (P = 0.04). Vitamins C and E supplementation had no significant effect on any of the studied parameters.

Bone marrow mesenchymal stem cells (BMSCs), as replacement cells of Schwann cells, can increase the effect of peripheral nerve repair. However, it has not yet reached any agreement to add the appropriate number of seeded cells in nerve scaffold. To investigate the effect of different number of BMSCs on the growth of rat dorsal root ganglia (DRG). Three 4-week-old Sprague Dawley (SD) rats (weighing 80-100 g) were selected to isolate BMSCs, which were cultured in vitro. Three 1- to 2-day-old SD rats (weighing 4-6 g) were selected to prepare DRG. BMSCs at passage 3 were used to prepare BMSCs-fibrin glue complex. According to different number of BMSCs at passage 3 in fibrin glue, experiment was divided into group A (1 x 10(3)), group B (1 x 10(4)), group C (1 x 10(5)), and group D (0, blank control), and BMSCs were co-cultured with rat DRG. The axon length of DRG, Schwann cell migration distance, and axon area index were quantitatively evaluated by morphology, neurofilament 200, and Schwann cells S-100 immunofluorescence staining after cultured for 48 hours. Some long cell processes formed in BMSCs at 48 hours; migration of Schwann cells and axons growth from the DRG were observed, growing in every direction. BMSCs in fibrin glue had the biological activity and could effect DRG growth. The axon length of DRG and Schwann cell migration distance in groups A, B, and C were significantly greater than those in group D (P < 0.05). The axon length of DRG and Schwann cell migration distance in group C were significantly less than those in group B (P < 0.05), but there was no significant difference between group A and group C, and between group A and group B (P > 0.05). The axon area index in groups A and B was significantly greater than that in group D (P < 0.05), but there was no significant difference between group C and group D (P > 0.05); there was no significant difference in groups A, B, and C (P > 0.05). In vitro study on DRG culture experiments is an ideal objective neural model of nerve regeneration. The effect of different number of BMSCs in fibrin glue on the growth of DRG has dose-effect relationship. It can provide a theoretical basis for the appropriate choice of the BMSCs number for tissue engineered nerve.

The aim of the present study was to investigate the protective effects of ischemic preconditioning on rats with renal ischemia-reperfusion injury and the effects on the expression of Bcl-2 and Bax. Thirty-six SD rats were randomly divided into three groups (n=12) including sham operation (S) group, ischemia-reperfusion group (I/R) group and ischemic preconditioning (IP) group. After anesthesia with intraperitoneal injection of chloral hydrate, bilateral renal pedicles were clipped for 45 min, followed by perfusion for 6 h to establish the I/R model. Both kidneys in rats of S group were separated and exposed for 45 min, but renal pedicles were not clipped. In IP group, bilateral renal pedicles were clipped for 5 min, followed by perfusion for 5 min, this procedure was repeated 3 times. Then bilateral renal pedicles were clipped for 45 min, followed by perfusion for 6 h. Blood samples were collected and rats were sacrificed to collect renal tissue. Levels of serum creatinine (Cr) and blood urea nitrogen (BUN) were measured. Activity of superoxide dismutase (SOD) was measured by xanthine oxidase assay. Degree of renal injury was evaluated by H&E staining. TUNEL kit was used to detect the number of apoptotic cells in renal tissue. Expression levels of Bcl-2 and Bax were detected by semi-quantitative PCR and western blot analysis at mRNA and protein levels, respectively. Results showed that levels of Cr and BUN in I/R and IP groups were significantly higher than those in S group, and levels of Cr and BUN in I/R group were significantly higher than that in IP group (P<0.05). Activity of SOD in I/R group and IP group were significantly lower than those in S group, and activity of SOD in I/R group were significantly lower than those in IP group (P<0.05). H&E staining showed that, compared with S group, renal injury in the I/R and IP groups was more serious than that in the S group, and I/R group was more serious than the IP group (P<0.05). TUNEL apoptosis assay showed that number of apoptotic cells in IP and I/R groups were significantly higher than that in the S group (P<0.01). Semi-quantitative PCR and western blot analysis showed that, compared with the S group, expression levels of Bcl-2 mRNA and protein were significantly decreased, expression levels of Bax mRNA and protein were significantly increased, and the ratio of Bcl-2/Bax was significantly decreased in the IP and I/R groups (P<0.01). Compared with the I/R group, expression level of Bcl-2 was significantly increased, the level of Bax was significantly deceased, and the ratio of Bcl-2/Bax was significantly increased in the IP group (P<0.01). As a result, ischemic preconditioning can protect rats with renal ischemia-reperfusion injury possibly by increasing the expression level of Bcl-2 and decreasing the expression level of Bax.

This randomized, placebo-controlled, blinded study investigated the hypoalgesic effects of high-frequency transcutaneous electrical nerve stimulation (TENS) delivered via a glove electrode compared with standard self-adhesive electrodes. Fifty-six TENS-naïve, healthy individuals (18 to 50 years old; 28 men, 28 women) were randomly allocated to 1 of 4 groups (n = 14 per group): glove electrode; placebo TENS using a glove electrode; standard electrode; and no treatment control. Active TENS (continuous stimulus, 100 Hz, strong but comfortable intensity) was applied to the dominant forearm/hand for 30 minutes. Placebo TENS was applied using a burst stimulus, 100-Hz frequency, 5-second cycle time for 42 seconds, after which the current amplitude was automatically reset to 0 mA. Pressure pain thresholds (PPTs) were recorded from 3 points on the dominant and nondominant upper limbs before and after TENS. Statistical analyses of dominant PPT data using between-within groups ANOVA showed significant differences between groups at all 3 recording points (P = .01). Post hoc Scheffe tests indicated no significant difference between the standard electrode and glove electrode groups. There was a significant hypoalgesic effect in the standard electrode group compared with the control group and between the glove electrode group and both the control and placebo TENS groups. There was no significant interactive effect between time and group at any of the recording points (P > .05). Perspective This study presents a comparison of the hypoalgesic effects of 2 different types of TENS electrode, a novel glove electrode and standard self-adhesive rectangular electrodes. The glove electrode provides a larger contact area with the skin, thereby stimulating a greater number of nerve fibers. The results show that both electrodes have similar hypoalgesic effects and therefore give the clinician another choice in electrode. PMID:19398378

The purpose of this study was to investigate the effectiveness of intratympanic dexamethasone injection as a therapeutic agent against cisplatin-induced ototoxicity. Animals were randomly divided into three groups. Group one received intraperitoneal cisplatin alone, group two, received intratympanic dexamethasone after cisplatin ototoxicity had been demonstrated. Group three, which is control group, received intratympanic dexamethasone.Then we made three measurements. First we measured the baseline distortion product otoacustic emission (DPOAEs) of all the guine pigs. Second we injected cisplatin intraperitoneal group one and two the same day. Third we measured DPOAEs after 72 h of group one and two. Moreover DPOAEs were measured at the end of the first and second week only in group two. Cochleae were harvested and processed for electron microscopy after then. Values of The DPOAEs amplitudes and signal-to-noise ratio (SNR) at 1-6 kHz frequencies for group 1 after the injections significantly decreased over those before injections (P < 0.05). In group 3, there were no significant differences in DPOAE amplitude and SNR values When they are compare before and after their intratympanic dexamethasone injections (P > 0.05). In group 2, the DPOAEs measurements were close to significance at the end of the second week (P = 0.056). Intratympanic dexamethasone injection did not cause any ototoxic effect. Although intratympanic dexamethasone did not reach the statistically significant results, the measurements were close to significance. Intratympanic dexamethasone might have a significant therapeutic effect after cisplatin ototoxicity with different dose and application regimens.

To study the effect of surface organic modified nano-silicon-oxide (SiO(x)) on mechanical properties of A-2186 silicone elastomers. Surface organic modified nano-silicon-oxide (SiO(x)) was added into A-2186 silicone elastomers by weight percentage of 2%, 4% and 6%. The one without addition served as a control. Standard specimens were made according to American Society for Testing Materials (ASTM). Their tensile strength, elongation at break, tear strength, and Shore A hardness were measured. The results were analyzed statistically by SPSS 10.0 software package. The tensile strength in the experimental groups was significantly lower than the control group (P<0.001).The elongation in the experimental groups was lower than the control group, but there was no significant difference between the 2wt% group and the control group (P=0.068). The tear strength in both the 2wt= group and 4wt= group were higher than the control group, and the difference was statistically significant; in addition, the tear strength in 2wt= group was higher than 4wt= group, which also showed statistical significance (P<0.001). With the increase of the added amount of surface modified nano-SiO(x), Shore A hardness increased and there was significant difference among them (P<0.001). Adding surface modified nano-SiO(x) has an effect on mechanical properties of A-2186 silicone elastomer, when 2wt= and 4wt= are added, tear strength of A-2186 improves significantly, with an increase of Shore A hardness and an decrease of tensile strength.

[Purpose] The purpose of the current study was to compare the effectiveness of motor sequential learning according to two different types of practice schedules, distributed practice schedule (two 12-hour inter-trial intervals) and massed practice schedule (two 10-minute inter-trial intervals) using a serial reaction time (SRT) task. [Subjects and Methods] Thirty healthy subjects were recruited and then randomly and evenly assigned to either the distributed practice group or the massed practice group. All subjects performed three consecutive sessions of the SRT task following one of the two different types of practice schedules. Distributed practice was scheduled for two 12-hour inter-session intervals including sleeping time, whereas massed practice was administered for two 10-minute inter-session intervals. Response time (RT) and response accuracy (RA) were measured in at pre-test, mid-test, and post-test. [Results] For RT, univariate analysis demonstrated significant main effects in the within-group comparison of the three tests as well as the interaction effect of two groups × three tests, whereas the between-group comparison showed no significant effect. The results for RA showed no significant differences in neither the between-group comparison nor the interaction effect of two groups × three tests, whereas the within-group comparison of the three tests showed a significant main effect. [Conclusion] Distributed practice led to enhancement of motor skill acquisition at the first inter-session interval as well as at the second inter-interval the following day, compared to massed practice. Consequentially, the results of this study suggest that a distributed practice schedule can enhance the effectiveness of motor sequential learning in 1-day learning as well as for two days learning formats compared to massed practice.

Because independent trials have provided evidence for the efficacy and effectiveness of the dissonance-based Body Project eating disorder prevention program, the present trial tested whether clinicians produce the largest intervention effects, or whether delivery can be task-shifted to less expensive undergraduate peer educators or to Internet delivery without effect size attenuation, focusing on acute effects. In this study, 680 young women (M age = 22.2 years, SD = 7.1) recruited at colleges in 2 states were randomized to clinician-led Body Project groups, peer-led Body Project groups, the Internet-based eBody Project, or an educational video control condition. Participants in all 3 variants of the Body Project intervention showed significantly greater reductions in eating disorder risk factors and symptoms than did educational video controls. Participants in clinician-led and peer-led Body Project groups showed significantly greater reductions in risk factors than did eBody Project participants, but effects for the 2 types of groups were similar. Eating disorder onset over 7-month follow-up was significantly lower for peer-led Body Project group participants versus eBody Project participants (2.2% vs. 8.4%) but did not differ significantly between other conditions. The evidence that all 3 dissonance-based prevention programs outperformed an educational video condition, that both group-based interventions outperformed the Internet-based intervention in risk factor reductions, and that the peer-led groups showed lower eating disorder onset over follow-up than did the Internet-based intervention is novel. These acute-effects data suggest that both group-based interventions produce superior eating disorder prevention effects than does the Internet-based intervention and that delivery can be task-shifted to peer leaders.

Myoclonus induced by etomidate during induction of general anesthesia is a common phenomenon. This prospective, randomized, saline-controlled clinical study was performed to evaluate the effect of parecoxib sodium pretreatment on the incidence and severity of etomidate-induced myoclonus. 60 patients, American Society of Anesthesiologists (ASA) physical status I or II, aged 20 to 60 years, who were scheduled to undergo elective laparoscopic cholecystectomy under general anesthesia, were allocated randomly into one of two groups to receive parecoxib sodium 40 mg intravenous (group P, n = 30) or the same volume of saline (group S, n = 30) 30 minutes before administration of etomidate (0.3 mg/kg). Myoclonus was assessed on a scale of 0 - 3. Postoperative side effects were recorded. The two groups were comparable with regard to baseline characteristics. The incidence of myoclonus was significantly lower in the parecoxib sodium group (11/30; 37%) than in the saline group (21/30; 70%) (p < 0.05). The severity of myoclonic movements was also significantly reduced by parecoxib sodium (p < 0.05). There were no significant differences between the two groups with respect to postoperative side effects. Pretreatment with intravenous injection of parecoxib sodium 40 mg significantly reduced the incidence and severity of etomidate-induced myoclonus without significant side effects.

The Telmisartan and Losartan Cardiac Evaluation Trial, a multicenter, prospective, randomized, open-labeled, blinded-endpoint trial, was designed to compare the effects of two angiotensin II receptor blockers (ARBs), telmisartan and losartan, on cardiovascular protection in Japanese patients with mild to moderate essential hypertension. We compared the effects of telmisartan and losartan on left ventricular (LV) hypertrophy, cardiac function, atherosclerosis of carotid arteries and surrogate markers related to the actions of peroxisome proliferator-activated receptor-γ. A total of 58 patients were enrolled in the present trial and the follow-up period was 1 year. There were no significant differences in blood pressure (BP) levels between the telmisartan group and the losartan group throughout the trial. The percentage of the patients treated with ARB monotherapy was significantly higher in the telmisartan group compared with the losartan group. In addition, the progression of intima-media thickness of common carotid artery was significantly inhibited in the telmisartan group compared with the losartan group. Neither group experienced significant changes in cardiac function and LV mass index. There were no differences between the groups with respect to changes in surrogate markers such as serum adiponectin, creatinine, homeostasis model assessment index, plasminogen activator inhibitor-1 and high sensitivity C-reactive protein. Although BP levels were equal and well controlled in both groups, telmisartan showed more protective vascular effects than losartan.

To observe the therapeutic efficacy of bronchoscopic interventional therapy on severe tuberculous main bronchial stenosis or atresia complicated with unilateral atelectasis. Ninety patients with severe tuberculous main bronchial stenosis or atresia complicated with unilateral atelectasis, who had received bronchoscopic interventional therapy, were divided into group A and B according to whether stents had been implanted or not. Patients in group A had been treated with electrocautery, balloon dilatation and cryotherapy. Group B had been treated with metallic stent implantation on the basis of the above interventional management. In order to observe the effectiveness, the time needed for taking effect and restenosis rate were noted. The efficacy between patients with different disease courses, radiology, bronchoscopy and dyspnea index were evaluated before treatment and after the patients' conditions were stable. Three months after treatment, the good response rate and the total effective rate of group B were higher than those of group A, 97% vs 42% (χ(2) = 29.595, P < 0.05), 100% vs 81% (χ(2) = 6.060, P < 0.05), respectively. The time needed for taking effect in group B was significantly shorter than that in group A, 0.25 month vs 1.6 month. The dyspnea indexes of both groups were significantly improved after treatment, but the improvement of group B was more significant than that of group A (u = -2.478, P < 0.05). The disease course of patients with different therapeutic efficacy was evaluated, and the median disease course was 2 months in good response efficacy patients, 3.5 months in improved patients, and 5 months in ineffective patients; the difference being significant between ineffective and good response efficacy patients (u = -3.079, P < 0.01). The restenosis rate of group B was significantly higher than that of group A, 72% vs 32% (χ(2) = 9.090, P < 0.01). The median restenosis time was 4 months in group A, and 6 months in group B. Bronchoscopy follow-up 12 months after the initial effective treatment showed that the good response rate and the total effective rate of group B were better than those of group A, 60% vs 29% (χ(2) = 10.559, P < 0.01), 88% vs 60% (χ(2) = 10.261, P < 0.01, respectively), and the total effective rate of main bronchial atresia patients in group B was significantly higher than that in group A, 90% vs 50% (Fisher's exact test, P < 0.05). There was no significant difference in effectiveness between severe stenosis and atresia patients in group A and B. Electrocautery, balloon dilatation, cryotherapy and stent implantation were effective methods to treat severe tuberculous main bronchial stenosis or atresia complicated with unilateral atelectasis. Among them, the therapeutic efficacy was better and the symptoms improved more quickly in patients with stent implantation. The efficacy of stent implantation was better than that of conventional interventional therapy, but the incidence of restenosis was also higher. Following-up should be emphasized in this group of patients. Disease courses were associated with the therapeutic efficacy; longer disease course was related to worse therapeutic efficacy, and restenosis occurred earlier. So interventional therapy should be initiated earlier for bronchial tuberculosis with dyspnea, especially for that complicated by atelectasis.

Postoperative nausea and vomiting (PONV) is a major concern for patients having surgery under general anesthesia as it causes subjective distress along with increased complications and delays in discharge from the hospital. Aromatherapy represents a complementary and alternative therapy for the management of PONV. The objective of this study was to compare the effectiveness of aromatherapy (QueaseEase, Soothing Scents, Inc, Enterprise, AL) versus an unscented inhalant in relieving PONV. One hundred twenty-one patients with postoperative nausea were randomized into a treatment group receiving an aromatic inhaler and a control group receiving a placebo inhaler to evaluate the effectiveness of aromatherapy. Initial and follow-up nausea assessment scores in both treatment and placebo groups decreased significantly (P < .01), and there was a significant difference between the two groups (P = .03). Perceived effectiveness of aromatherapy was significantly higher in the treatment group (P < .001). Aromatherapy was favorably received by most patients and represents an effective treatment option for postoperative nausea. Published by Elsevier Inc.

Obesity is a major health problem. We investigated the effects of forskolin and rolipram in the diet of animals in which obesity had been induced. We used 50 female albino Wistar rats that were assigned randomly into five groups as follows: group 1, control; group 2, high fat diet; group 3, high fat diet + forskolin; group 4, high fat diet + rolipram; and group 5, high fat diet + rolipram + forskolin. The rats were fed for 10 weeks and rolipram and forskolin were administered during last two weeks. The animals were sacrificed and blood samples were obtained. Serum cAMP, cGMP and free fatty acids (FFA) levels were measured using ELISA assays. We also measured weight gain during the 10 week period. cAMP and FFA levels of groups 3, 4 and 5 were significantly higher than those of groups 1 and 2. We found no significant differences in serum cGMP levels among the groups. The weight gain in groups 3, 4 and 5 was significantly less than for group 2. We also found that the weight gain in group 5 was significantly less than in groups 3 and 4. We found that both forskolin and rolipram stimulated lipolysis and inhibited body weight increase by increasing cAMP levels. Also, combination therapy using the two agents may be more effective in preventing diet induced obesity than either agent alone. We found also that these agents did not effect cellular cGMP levels in diet induced obesity.

Activation of aryl hydrocarbon receptor (AhR) leads to diverse outcome in various kinds of cells. AhR activation may induce apoptosis or prevent of apoptosis and cell death. Recent studies suggest that apoptosis effects of AhR can be modulated by inflammatory cytokine like tumor necrosis factor alpha (TNF-α). In this study, we try to investigate the possible interaction of TNF-α with the 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin (TCDD), a ligand of AhR, on peripheral lymphocytes. Human peripheral blood mononuclear cells (PBMCs) were isolated from peripheral blood by discontinuous density gradient centrifugation on ficoll. Isolated PBMCs were divided into four groups: Control group, TNF-α administered group, TCDD administered group, co-administered group with TCDD and TNF-α. Cells were maintained for a week in lymphocyte culture condition. Then, TNF-α was added to group 2 and 4. Finally, apoptosis and necrosis were analyzed in all samples using flowcytometry. In group 4, the mean percent of necrosis and apoptosis in TCDD treatment groups was significantly larger than other groups; (P < 0.05). Furthermore, there was no significant difference between the mean percent of cell death in TNF-α administered group and TCDD administered group (P > 0.05). However, the mean percent of cell death in co-administered group with TCDD and TNF-α was significantly lower than other groups; (P < 0.05). TNF-α could significantly inhibit effects of TCDD on lymphocytes apoptosis. Combination effects of TNF-α and TCDD on lymphocyte increase cell survival.

Significant rates of psychological distress occur in implantable cardioverter defibrillator (ICD) patients. Research has demonstrated that women are particularly at risk for developing distress and warrant psychosocial attention. The major objectives were to implement and test the effectiveness of a female-specific psychosocial group intervention on disease-specific quality of life outcomes in outpatient female ICD recipients versus a wait-list control group. Twenty-nine women were recruited for the study. Fourteen women were randomized to the intervention group and participated in a psychosocial intervention focused on female-specific issues; 15 were randomized to the wait-list control group. All women completed individual psychological batteries at baseline and at 1-month follow-up measuring shock anxiety and device acceptance. Pre-post measures of shock anxiety demonstrated a significant time by group interaction effect with the intervention group having a significantly greater decrease (Pillai's trace = 5.58, P = 0.026). A significant interaction effect (Pillai's trace = 5.05, P = 0.046) was found, such that women under the age of 50 experienced greater reduction in shock anxiety than their middle-aged cohorts. Pre-post measures of device acceptance revealed a significant time by group interaction effect with the intervention group having significantly greater increases (Pillai's trace = 5.80, P = 0.023). Structured interventions for female ICD patients involving ICD-specific education, cognitive behavioral therapy strategies, and group social support provide improvements in shock anxiety and device acceptance at 1-month re-assessment. Young women appear to be an at-risk subgroup of this population and may experience more benefit from psychosocial treatment targeting device-specific concerns. ©2010, The Authors.

To compare the local anesthetic effects of tramadol hydrochloride with those of lidocaine in circumcision procedures. We also investigated the effect of child anxiety on pain level. A total of 70 children were included in this study. The children were randomized into 3 groups. Group 1 (n = 26) received lidocaine hydrochloride + epinephrine and they underwent circumcision using Ali's clamp(®). Group 2 (n = 35) received lidocaine hydrochloride + epinephrine and group 3 (n = 12) 5% tramadol. The last two groups underwent conventional circumcision. The mean anxiety score was 22.6. We did not find significant differences in terms of anxiety score among the groups (p = 0.761). When the pain scores of the groups during injection were compared, it was found that there were no significant differences. However, the pain score of the third group was significantly high when it was compared with the first and second group 2 and 10 min after injection. In the correlation analysis, we found a positive correlation between children's anxiety scores and the pain degree during injection (r = 0.373, p = 0.001). Tramadol may not provide effective local anesthesia in male circumcision. The child's anxiety before the circumcision seems to have a negative effect on pain level.

To compare the effectiveness ofradial extracorporeal shock wave therapy (rSWET) and ultrasound therapy (US) in the treatment of chronic plantar fasciitis. Randomized controlled trial. Department of Rehabilitation Medicine, King Chulalongkorn Memorial Hospital. Thirty patients who were diagnosed with plantar fasciitis for at least 3 months and who had not responded to other forms of conservative treatment were recruited for this study. They were randomly divided into two groups of 15 patients. The rESWT group was treated with 1 session per week and the US group with 3 sessions per week, with both groups undergoing a total of 6 consecutive weeks of treatment. Visual analog scale (VAS) assessments were performed before and after treatment at 1, 3, 6, 12, and 24 weeks. The mobility subscale of the plantar fasciitis pain and disability scale (PFPS) was measured before and after treatment. Patient satisfaction was evaluated at the conclusion of the 6-week treatment protocol. VAS pain intensity scores were significantly decreased in both groups (p < 0.001), when measured after treatment at 1, 3, 6, 12, and 24 weeks. The VAS pain scores for the rESWT group dropped significantly more than those of the US group (p < 0.001). At the end of treatment, the PFPS mobility subscale scores in both groups were significantly decreased (p < 0.001). Similar to the VAS pain score outcome, the PFPS mobility subscale score for the rESWT group decreased significantly more than that of the US group (p < 0.001). Patient satisfaction was significantly higher in the rESWT group, relative to the US group (p = 0.025). In chronic plantar fasciitis treatment, both rESWT and US were found to be effective in reducing pain and increasing mobility; however, statistical analysis showed that rESWT is significantly more effective than US.

The no/slow reflow phenomenon during primary percutaneous coronary intervention (PPCI) causes the destruction of the coronary microcirculation and further myocardial damage. Some studies have shown that intracoronary nitroprusside infusion is a safe and effective method for managing the no/slow reflow phenomenon. However, it is uncertain whether the injection of nitroprusside at a specific time point during PPCI can most effectively prevent no-reflow. In this study, we investigated the effect of the timing of an intracoronary nitroprusside injection on flow recovery during PPCI in patients with ST elevation acute myocardial infarction (STEMI). One hundred twenty consecutive patients with STEMI who underwent PPCI were enrolled in the study. Patients who fulfilled the eligibility criteria were randomly allocated to three groups: control group (N.=40) received no nitroprusside before they completed PCI; the second group (N.=40) received nitroprusside before balloon dilatation; and the third group (N.=40) received nitroprusside after each balloon dilatation and before contrast agent refilling. The baseline clinical variables and the details of the PCI procedure were collected. The thrombolysis in myocardial infarction (TIMI) flow grades and the corrected TIMI frame count (cTFC) were evaluated immediately after stent implantation was completed. There were no significant differences in the baseline characteristics, antithrombotic drugs given before PCI, and details of the PCI procedure among the three groups (P>0.05). The incidence of TIMI grade 3 after PCI was significantly higher in the nitroprusside group than in the control group (P=0.025), whereas cTFC was significantly lower in the nitroprusside group (26.6±15.2) than in the control group (38.1±21.3, P=0.001). The incidence of TIMI grade 3 after PCI was significantly higher in the third group than in the second group (P=0.045), and cTFC was significantly lower in the third group (21.5±9.5) than in the second group (31.2±18.3, P=0.002). Multivariable linear regression analyses showed that the intracoronary nitroprusside injection time was a significant predictor of cTFC after PCI. These data suggest that the intracoronary injection of nitroprusside significantly reduced the incidence of no/slow reflow during PPCI. The intracoronary injection of nitroprusside most effectively prevented the no/slow reflow phenomenon when administered between balloon dilatation and contrast agent refilling during PPCI.

A total of 70 women in a postpartum care center were recruited and were assigned to the experimental group (35) or control group (35). Foot reflexology massage was provided to the experimental group once a day for three days. Data were collected before and after the intervention program which was carried out from December, 2013 to February, 2014. Data were analyzed using Chi-square test, Fisher's exact test, and t-test. The level of fatigue in the experimental group was significantly lower than the control group (t=-2.74, p=.008). The level of cortisol in the urine of women in the experimental group was significantly lower than the control group (t=-2.19, p=.032). The level of depression in the experimental group was significantly lower than the control group (t=-3.00, p=.004). The results show that the foot reflexology massage is an effective nursing intervention to relieve fatigue, stress, and depression for postpartum women.

Use of a random skin flap is common for repairing wounds and for reconstruction. Lidocaine is a traditional local anesthetic that blocks sodium channels and has positive effects on ischemia-reperfusion injury. To investigate the effects of lidocaine on random skin flap survival in rats. McFarlane flaps were established in 20 rats divided into 2 groups. Lidocaine was injected in the lidocaine group, and the same concentration of saline was injected in the control group. The survival area of the flaps was measured on Day 7. Levels of inflammation were evaluated by hematoxylin and eosin (H&E)-stained slices, and superoxide dismutase and malonyldialdehyde contents were examined. The mean survival area of the flaps in the lidocaine group was significantly larger than that in the control group. Superoxide dismutase activity increased significantly in the lidocaine group compared with that in the control group. Malonyldialdehyde level in the lidocaine group was significantly lower than that in the control group. The H&E-stained slices showed that inflammation was clearly inhibited in the lidocaine group. Lidocaine improved the survival of random skin flaps.

Aim This study aimed to evaluate the effect of NAFLD on CIMT as a risk factor for atherosclerosis. Background The prevalence of non-alcoholic fatty liver disease (NAFLD) is increasing worldwide due to rise of obesity and diabetes mellitus (DM) prevalence. Non-invasive assessment of carotid intima-media thickness (CIMT) by high-resolution carotid B-mode ultrasonography is widely used for determining the atherosclerosis. Patients and methods In this case-control setting, 151 subjects were categorized in three groups: group I including 49 patients with NAFLD and DM; group II including 50 non-diabetic NAFLD patients; and the control including 52 normal subjects as group III. The right and left CIMTs and its maximum reading (CIMTmax) were measured by a skilled sonographist blind to the groups. The sonographic grading of the NAFLD was determined in group I and II. Results Median CIMTmax was significantly higher in group I comparing with group II and control group (p<0.001). This difference between group I and group II was not significant after adjusting for age and history of hypertension and hyperlipidemia (p=0.089). After controlling the confounders, there was statistical significant between group I and group II with the control group (p<0.05). There was no significant difference in median maximal thickness of intima-media in the carotid of group I compare to group II in patients with and without elevated liver enzymes (in both groups, 0.6 mm, p= 0.402). Conclusion Based on our findings, there is a significant association between the presence of NAFLD and atherosclerosis. This association was independent to the DM presence. The grade of NAFLD and elevated liver function tests had no effect on severity of atherosclerosis. PMID:25436098

To investigate effectiveness of rotator cuff repair with manipulation release and arthroscopic debridement for rotator cuff tear with shoulder stiffness. A retrospectively study was performed on the data of 15 patients with rotator cuff tear combined with shoulder stiffness (stiff group) and 24 patients without stiffness (non-stiff group) between January 2014 and December 2015. The patients in the stiff group underwent arthroscopic rotator cuff repair with manipulation release and arthroscopic debridement while the patients in the non-stiff group only received arthroscopic rotator cuff repair. The patients in the stiff group were older than the patients in the non-stiff group, showing significant difference ( P <0.05). There was no significant difference in gender, type of rotator cuff tear, side of rotator cuff tear, and combined with diabetes between 2 groups ( P >0.05). The visual analogue scale (VAS) score, University of California Los Angeles (UCLA) score, American Shoulder and Elbow Surgeons (ASES) score, and range of motion (ROM) were used to evaluate the effectiveness after operation. All incisions healed by first intention without any complication after operation. The patients were followed up 13-31 months in the stiff group (mean, 19.2 months) and 13-23 months in the non-stiff group (mean, 20.3 months). There was no significant difference in follow- up time between 2 groups ( t =-0.573, P =0.570). The VAS score in the stiff group was higher than that in the non-stiff group before operation ( t =-2.166, P =0.037); there was no significant difference between 2 groups at 3, 6, 12 months and last follow-up ( P >0.05). The forward flexion and external rotation were significantly lower in the stiff group than those in the non-stiff group before operation and at 3 months after operation ( P <0.05); there was no significant difference between 2 groups at 6, 12 months and last follow-up ( P >0.05). At last follow-up, the internal rotation was beyond L 3 level in 2 groups. The preoperative UCLA score was significant lower in the stiff group than that in the non-stiff group ( P =0.037); but there was no significant difference in UCLA score at last follow-up between 2 groups ( P =0.786). There was no significant difference in pre- and post-operative ASES scores between 2 groups ( P >0.05). Satisfactory effectiveness can be achieved in the patients with rotator cuff tear combined with shoulder stiffness after rotator cuff repair with manipulation release and arthroscopic debridement, although the patients with shoulder stiffness had slower postoperative recovery of ROM until 6 months after operation.

Glucocorticoid-induced osteoporosis (GIO) is one of the serious side effects which have become the most common secondary osteoporosis. The purpose of this study is to evaluate the effect of aqueous extract of parsley, basil and chicory on glucocorticoid-induced osteoporosis in rats. Fifty Female rats were divided into five groups and treated for 8 weeks as follow: group 1 served as control; group (2) subcutaneously injected with 0.1 mg/kg b. wt. dexamethasone dissolved in saline; group 3 received similar dose of dexamethasone together with aqueous parsley extract in a dose of 2 g/kg b. wt.; group 4 received similar dose of dexamethasone together with 400 mg/kg b. wt. aqueous basil extract and group 5 received similar dose of dexamethasone together with 100 mg/kg b. wt. aqueous chicory extract. The dexamethasone group showed a significant decrease in serum E2, Ca, P levels and significant decrease in total BMD, BMC and a significant increase in serum PTH, ALP and ACP. Bone TBARs was significantly increased while GSH, antioxidant enzymes were significantly decreased. These changes were attenuated by parsley, basil and chicory extracts in the group 3, 4 and 5 respectively. Aqueous extracts of parsley, basil and chicory showed bone protection against glucocorticoid-induced in rats. From our results, we concluded that chicory has a potent protective effect more than parsley and basil due to containing flavonoids and inulin.

Allium ampeloprasum (AA) is a medicinal plant which is used in Iranian traditional medicine to treat or prevent different diseases. The aim of this study is to investigate the effect of AA extract on oxidative stress and dyslipidemia in diabetic rats induced by alloxan. In this experimental study, 60 male Wistar rats weighing 200-250gr were randomly divided to five groups of 12 each including healthy control (group I), diabetic control (group II), metformin-treated diabetic positive control (group III) and two groups treated with doses 400 (group IV) and 800 (groupV) mg/kg/BW of AA extracts. Diabetes mellitus was experimentally induced by injection of two doses of alloxan-120 and 65mg/kg-within two consecutive days. Alloxan-induced diabetes caused significant increase in serum glucose, triglyceride (TG), total cholesterol (TC), low density lipoprotein (LDL), very low density lipoprotein (VLDL) and high density lipoprotein (HDL) levels in group II (p<0.05). Furthermore, serum malondialdehyde (MDA) levels increased significantly and liver catalase activity decreased significantly in the 2nd group compared to 1st control; respectively p=0.0001 and p=0.009. In the group IV has seen a significant decrease in serum TG (p=0.01), TC (p=0.0001), VLDL (p=0.01), and MDA (p=0.0001) levels and significant increase in the liver and kidney catalase activities of the rats compared to the group II; respectively p=0.0001 and p=0.0001. In Conclusion our results highlight potentially relevant health beneficial effects of AA extract which exerts hypoglycemic, hypolipidemic, and anti-oxidative stress effects in rats with alloxan-induced diabetes. Therefore, it may be considered as useful dietary supplements in diabetic patients. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

To investigate the effects of thermochemotherapy with mitomycin C (MMC) on normal rabbit bladder urothelium and to compare it with standard intravesical MMC and hyperthermia with normal saline. Twenty-four male New Zealand rabbits, with a mean weight of 2.7 kg (in weight of 2.1–4.3 kg), were divided into three groups, each containing eight rabbits. Thermotherapy with only normal saline was performed in the first group, standard intravesical MMC was performed in the second group, and thermotherapy with MMC was performed in the last group. A week after the primary procedure, total cystectomy was performed and tissue samples were evaluated. The presence of epithelial vacuolar degeneration (p = 0.001), epithelial hyperplasia (p = 0.000), subepithelial fibrosis (p = 0.001) and hemorrhagic areas in the connective tissue (p = 0.002) was observed statistically significantly higher in the standard MMC group than in thermotherapy with normal saline group. There was almost a significant difference among standard MMC and normal saline group in terms of vascular congestion in the connective tissue (p = 0.08). Presence of epithelial vacuolar degeneration (p = 0.002), epithelial hyperplasia (p = 0.002), subepithelial fibrosis (p = 0.030), hemorrhagic areas (p = 0.011) and vascular congestion (p = 0.36) in the connective tissue was observed statistically significantly higher in the thermochemotherapy with MMC group than in standard intravesical MMC group. Polymorphonuclear cell infiltration was not considerable in any of the groups, and there was no significant difference between each groups (p = 0.140). Administration of intravesical MMC causes a toxic effect on the normal urothelium of the bladder rather than an inflammatory reaction. Heating MMC significantly increased this effect.

To investigate the effects of electromagnetic radiation on the physiological indices and immune function of operators. The general conditions and electromagnetic radiation awareness rate of 205 operators under electromagnetic radiation were evaluated using a self-designed questionnaire. Physical examination, electrocardiography, and routine urine test were performed in these operators. Peripheral blood was collected from the operators under electromagnetic radiation for blood cell counting and biochemical testing, and their peripheral blood lymphocytes were cultured for determination of chromosomal aberrant frequency and micronucleus frequency. The data from these operators (exposure group) were compared with those of 95 ordinary individuals (control group). The chief complaint of giddiness, tiredness, dizziness, and amnesia showed significant differences between the exposure group and control group (P < 0.01), and the difference in headache became larger with an increase in working years. The awareness rate of electromagnetic radiation damage was significantly higher in the exposure group than in the control group. The difference in bradycardia was significant between the two groups (P <0.01), and the incidence was higher with longer working years. Significant differences between the two groups were also found in the numbers of individuals with elevated alanine aminotransferase, total bilirubin, and direct bilirubin (P < 0.01), populations with increased lymphocyte ratio and decreased neutrophil ratio (P < 0.01), populations with positive occult blood, urobilinogen, and bilirubin tests, and the number of individuals with increased micronucleus frequency of cultured peripheral blood lymphocytes (P < 0.01). In addition, the exposure group had significantly increased complement C3 and C4 (P < 0.01), significantly increased IgG (P < 0.05), and significantly decreased IgM (P < 0.01), as compared with the control group. Electromagnetic radiation may lead to the changes in physiological indices, genetic effects, and immune function and affect the health and immune function in operators. The adverse effects are increased as the working years increase. So it is important to strengthen occupational protection of operators under electromagnetic radiation.

This study aims to determine the long-term effects of a new Memory Self-efficacy (MSE) training program for stroke patients on MSE, depression, and quality of life. In a randomized controlled trial, patients were allocated to a MSE training or a peer support group. Outcome measures were MSE, depression, and quality of life, measured with the Metamemory-In-Adulthood questionnaire, Center for Epidemiological Studies-Depression Scale (CES-D), and the Who-Qol Bref questionnaire, respectively. We used linear mixed models to compare the outcomes of both groups immediately after training, after 6 months, and after 12 months, adjusted for baseline. In total, 153 former inpatients from 2 rehabilitation centers were randomized-77 to the experimental and 76 to the control group. MSE increased significantly more in the experimental group and remained significantly higher than in the control group after 6 and 12 months (B = 0.42; P = .010). Psychological quality of life also increased more in the experimental group but not significantly (B = 0.09; P = .077). However, in the younger subgroup of patients (<65 years old), psychological quality of life significantly improved in the experimental group compared to the control group and remained significantly higher over time (B = 0.14; P = .030). Other outcome measures were not significantly different between both groups. An MSE training program improved MSE and psychological quality of life in stroke patients aged <65 years. These effects persisted during 12 months of follow-up.

Feelings of romanticism and self-esteem among pregnant adolescents, adolescent mothers, and a control group of nonpregnant, nonparenting adolescents were investigated. The Bachman Self-Esteem Scale (Bachman, O'Malley, & Johnston, 1978) and the Dean Romanticism Scale (Dean, 1961) were distributed to 649 U.S. female adolescents--255 pregnant adolescents, 121 adolescent mothers, and 273 teenagers in the control group. For romanticism, the results indicated a significant main effect for group (pregnant teens, teen mothers, and a control group consisting of nonpregnant, nonparenting teenagers) and ethnicity (White, Hispanic, African American, and Asian) but not for age (13 to 15 years and 16 to 19 years). The pregnant teens and teen mothers thus had a higher degree of romanticism than the control group did. For self-esteem, there was a significant main effect for race, but not for group or for age. This main effect was qualified by a significant interaction between ethnicity and age.

The current study examined the effects of aromatherapy massage on alleviating agitation and depressive mood in individuals with dementia. A randomized controlled trial and repeated measures design was conducted. A total of 59 participants were randomly assigned to intervention or control groups. The intervention group received aromatherapy massage once per week for 8 weeks. Results indicated no significant changes over time in overall agitation for either group, but agitation decreased from Week 1 to Week 5 for the intervention group. In addition, the overall depressive symptoms decreased significantly over time for the intervention group compared to the control group (p < 0.001). However, changes in agitation within 24 hours following aromatherapy massage showed some significant changes in Weeks 5 and 9. Aromatherapy massage can be an effective and safe intervention to alleviate specific agitated behaviors and depressive mood in individuals with dementia.

Pain is a common and significant symptom in many individuals with multiple sclerosis (MS). The presence and severity of pain in individuals with MS has also been shown to be associated with higher levels of depression, functional impairment, and fatigue. It is common for MS patients and their caregivers to worry about narcotic addiction in the management of chronic pain. Therefore, this study aimed to determine and compare the effects of reflexology and relaxation on pain in women suffering from MS. This study was a single-blind randomized clinical trial performed on 75 patients with MS referred to the MS Clinic of Ayatollah Kashani Hospital (Isfahan, Iran). After simple non-random sampling, using the minimization method, participants were randomly assigned to the three groups of reflexology, relaxation, and control. In the experimental groups, foot reflexology and relaxation interventions (Jacobson and Benson) were performed within 4 weeks, twice a week for 40 min. The control group received routine care and medical treatment as directed by a doctor. Data were collected using the Numerical Rating Scale before, immediately after, and 2 months after interventions in all three groups. Data analysis was performed using SPSS version 18 and descriptive and inferential statistical tests. Findings obtained from analysis of variance (ANOVA) showed no significant differences between mean pain intensity scores in the three groups preintervention and 2 months after interventions (p > 0.05). However, this difference was statistically significant immediately after the study (p < 0.05). Findings obtained from repeated measures ANOVA showed that the severity of pain significantly differed during different times in reflexology and relaxation (p < 0.05); however, this difference was not significant in the control group (p > 0.05). Furthermore, Fisher's least significant difference (LSD) revealed a significantly higher reduction in pain intensity scores in the reflexology group after the intervention, compared with the two other groups, but showed no significant differences between relaxation and control groups. There were no significant differences between the three groups 2 months after the interventions (p > 0.05). The results showed that both interventions are effective on relieving pain in women with MS; however, it appears that the effect of reflexology on pain reduction is greater than that of relaxation. Hence, these two methods can be recommended as effective techniques.

In the present study, a porcine system was supplemented with sorbitol during in vitro maturation (IVM) or in vitro culture (IVC), and the effects of sorbitol on oocyte maturation and embryonic development following parthenogenetic activation were assessed. Porcine immature oocytes were treated with different concentrations of sorbitol during IVM, and the resultant metaphase II stage oocytes were activated and cultured in porcine zygote medium-3 (PZM-3) for 7 days. No significant difference was observed in cumulus expansion and the nuclear maturation between the control and sorbitol-treated groups, with the exception of the 100 mM group, which showed significantly decreased nuclear maturation and cumulus expansion. There was no significant difference in the intracellular reactive oxygen species (ROS) levels between oocytes matured with 10 or 20 mM sorbitol and control groups, but 50 and 100 mM groups had significantly higher ROS levels than other groups. The 20 mM group showed significant increases in intracellular glutathione and subsequent blastocyst formation rates following parthenogenetic activation compared with the other groups. During IVC, supplementation with sorbitol significantly reduced blastocyst formation and increased the apoptotic index compared with the control. The apoptotic index of blastocysts from the sorbitol-treated group for entire culture period was significantly higher than those of the partially sorbitol-exposed groups. Based on these findings, it can be concluded that the addition of a low concentration of sorbitol (20 mM) during IVM of porcine oocytes benefits subsequent blastocyst development and improves embryo quality, whereas sorbitol supplement during IVC has a negative effect on blastocyst formation.

This meta-analysis examined the effects of process-based executive-function and working memory training (49 articles, 61 independent samples) in older adults (> 60 years). The interventions resulted in significant effects on performance on the trained task and near-transfer tasks; significant results were obtained for the net pretest-to-posttest gain relative to active and passive control groups and for the net effect at posttest relative to active and passive control groups. Far-transfer effects were smaller than near-transfer effects but were significant for the net pretest-to-posttest gain relative to passive control groups and for the net gain at posttest relative to both active and passive control groups. We detected marginally significant differences in training-induced improvements between working memory and executive-function training, but no differences between the training-induced improvements observed in older adults and younger adults, between the benefits associated with adaptive and nonadaptive training, or between the effects in active and passive control conditions. Gains did not vary with total training time. © The Author(s) 2014.

There is evidence that substantial weight loss through bariatric surgery (BS) may result in short-term improvement of migraine severity. However, it still remains to be seen whether smaller amounts of weight loss have a similar effect on migraine headache. This study has been designed to compare the effects of weight reduction through BS and non-surgical modifications. Migraine characteristics were assessed at 1 month before (T0), 1 month (T1), and 6 months (T2) after BS (vertical sleeve gastrectomy (VSG) (n = 25) or behavioral therapy (BT) (n = 26) in obese women (aged 18-60 years) with migraine headache. Migraine was diagnosed using the International Classification of Headache Disorders (ICHDIIβ) criteria. There was significant reduction in the visual analog scale (VAS) from the baseline to T1 and T2 in both groups. The number of migraine-free days showed a significant increase within each group (p < 0.001). The BS group had a significant reduction in attack duration (p < 0.001) while there were no changes observed within the BT group. Following the adjustment of ANCOVA models for baseline values of migraine characteristics, age, changes in weight, BMI, body fat, and fat-free mass from T0 to T2, the BS group showed statistically significant lower VAS and duration of migraine attacks and a significantly higher number of migraine-free days than the BT group at T1 and T2 (p ≤ 0.028). Our results indicated that far before significant weight reduction after BS (VSG), there was marked alleviation in the severity and duration of migraine and a significant increase in the number of migraine-free days in obese female migraineurs. However, the effects in the BT group were not comparable with the effects in the BS group.

The purpose of this cross-over experimental study was to examine effects of music intervention on maternal anxiety, fetal heart rate pattern and testing time during non-stress tests (NST) for antenatal fetal assessment. Sixty pregnant women within 28 to 40 gestational weeks were randomly assigned to either the experimental group (n=30) or control group (n=30). Music intervention was provided to pregnant women in the experimental group during NST. Degree of maternal anxiety and fetal heart rate pattern were our primary outcomes. State-trait anxiety inventory, blood pressure, pulse rate, and changes in peripheral skin temperature were assessed to determine the degree of maternal anxiety. Baseline fetal heart rate, frequency of acceleration in fetal heart rate, fetal movement test and testing time for reactive NST were assessed to measure the fetal heart rate pattern. The experimental group showed significantly lower scores in state anxiety than the control group. There were no significant differences in systolic blood pressure and pulse rate between the two groups. Baseline fetal heart rate was significantly lower in the experimental group than in the control group. Frequency of acceleration in fetal heart rate was significantly increased in the experimental group compared to the control group. There were no significant differences in fetal movement and testing time for reactive NST between the two groups. Present results suggest that music intervention could be an effective nursing intervention for alel viating anxiety during non-stress test.

To investigate the effects of training sessions on circulating β-endorphin changes in sport horses before and after competition and to ascertain whether competition would affect this response. A total of 24 trained jumping horses were randomly assigned to one of two training groups: Group A (competing) and Group B (not competing). To determined plasma β-endorphin concentrations, two pre- and post-competition training weeks at aerobic workout and two competitive show jumping event days at anaerobic workout were measured before, 5 and 30 min after exercise. Exercise intensity is described using lactate concentrations and heart rate. The circuit design, intensity, and duration of training sessions were the same for both groups. In Group A, one-way analysis of variance for repeated measures (RM-ANOVA) showed significant effects of exercise on β-endorphin changes (F=14.41; p<0.001), only in the post-competition training sessions, while in Group B showed no significant effects. Two-way RM-ANOVA showed, after post-competition training sessions, a significant difference between Group A and Group B (F=6.235; p=0.023), with higher β-endorphin changes in Group A, compared to Group B. During the competitive show jumping sessions, one-way RM ANOVA showed significant effects of exercise on β-endorphin changes (F=51.10; p<0.001). The statistical analysis, in Group A, showed a significant difference between post-competition training and competitive exercise (F=6.32; p=0.024) with higher β-endorphin values in competitive sessions compared to those of post-competition training. Lactate concentrations seem to be the main factors being correlated with the raise of β-endorphin during anaerobic exercise of competitive events. Exercise of low intensity, as well as that one of training sessions, does not appear to stimulate a significant increased release of β-endorphin and it may depend on the duration of the exercise program. Moreover, the responses during exercise in the course of post-competition training sessions seem to be significantly different from those the pre-competition training. These data show that the preliminary competitive stress induced additional significant changes of β-endorphin pattern. It would reflect the need of a long-lasting modulation of fatigue and pain perception related to the effect of an additional physical and mental effort for the consecutive competitive and training sessions.

The aim of this study is to investigate the effect of rectal ozone and intratympanic ozone therapy on cisplatin-induced ototoxicity in rats. Eighteen female Wistar albino rats were included in our study. External auditory canal and tympanic membrane examinations were normal in all rats. The rats were randomly divided into three groups. Initially, all the rats were tested with distortion product otoacoustic emissions (DPOAE), and emissions were measured normally. All rats were injected with 5-mg/kg/day cisplatin for 3 days intraperitoneally. Ototoxicy had developed in all rats, as confirmed with DPOAE after 1 week. Rectal and intratympanic ozone therapy group was Group 1. No treatment was administered for the rats in Group 2 as the control group. The rats in Group 3 were treated with rectal ozone. All the rats were tested with DPOAE under general anesthesia, and all were sacrificed for pathological examination 1 week after ozone administration. Their cochleas were removed. The outer hair cell damage and stria vascularis damage were examined. In the statistical analysis conducted, a statistically significant difference between Group 1 and Group 2 was observed in all frequencies according to the DPOAE test. In addition, between Group 2 and Group 3, a statistically significant difference was observed in the DPOAE test. However, a statistically significant difference was not observed between Group 1 and Group 3 according to the DPOAE test. According to histopathological scoring, the outer hair cell damage score was statistically significantly high in Group 2 compared with Group 1. In addition, the outer hair cell damage score was also statistically significantly high in Group 2 compared with Group 3. Outer hair cell damage scores were low in Group 1 and Group 3, but there was no statistically significant difference between these groups. There was no statistically significant difference between the groups in terms of stria vascularis damage score examinations. Systemic ozone gas therapy is effective in the treatment of cell damage in cisplatin-induced ototoxicity. The intratympanic administration of ozone gas does not have any additional advantage over the rectal administration.

Lead poisoning has been reported in almost every country on earth. In this study the effect of experimental lead pellet intake (2-6 pellets per week [groups B2, B4, B6] and ad libitum [BAD] accessibility for 10 weeks) on its distribution in liver, kidney, pectoral muscle, ovary, eggs and the effect of selected reproductive parameters (egg weight, fertilization, hatchability) was analyzed in breeding pheasants. Lead pellets were force fed to the digestive tract (struma, ingluvies) and the ingestion was controlled. Concentration of lead was detected using the atomic absorption spectrophotometry. Analysis of the lead concentration in liver showed a significantly higher concentration in all group after the lead pellets intake. The increase of the lead concentration was dose-dependent and the concentration detected in group BAD was similar as in group B2. Very similar tendencies were detected for the lead concentration in kidney. The accumulation of lead in pectoral muscle was lower, in comparison with liver and kidney. Compared to lead concentration detected in ovary of the control group a significant increase was detected in all experimental groups, reaching the maximum in the group B6. Similar significant increase of lead concentration was detected in eggs. The average weight of eggs was 32.01 ± 2.71 g in the control group and lower in all experimental groups, but this decrease was significant only in the group B6. The fertilization rate was the highest in the control group and a dose-dependent decrease was detected with the lowest value in the group B6. For egg hatching ratio a significant decrease was detected in groups B4 and B6. Results of this study clearly describe accumulation of lead in the body and a its negative effect on the reproductive parameters. In the ad libitum experimental group the most similar results were found as in group B2, suggesting a rate of "natural" lead pellet intake.

Background: During preoperative radiotherapy, effective doses of ionizing radiation occasionally cause wound complications after subsequent surgery. This study was designed to determine the effects of intraperitoneally or orally administered N-acetylcysteine (NAC) on anastomotic healing of irradiated rats. Material & Methods: Forty Wistar albino rats were randomized into four groups containing 10 rats each. A 3 cm long surgical full-thickness midline laparotomy was performed to all groups (Groups 1-4). Group 1 was designed as a control group without radiation therapy and NAC treatment. Groups 2, 3 and 4 received a single abdominal dose of 10 Gy irradiation before laparotomy and groups 3 and 4 received oral and intraperitoneal NAC, respectively. Results: Group comparisons demonstrated that breaking strength was significantly higher in NAC treated rats. A statistically significant difference was determined in terms of superoxide dismutase (SOD), malondealdehyde (MDA) and glutation (GSH) values between groups (p<0.001). Nevertheless, advanced oxidation protein products (AOPP) levels were found to be similar between groups (p=0.163). Serum GSH and SOD levels were significantly higher in groups 3 and 4 when compared to group 2 (p < 0.05). Similarly, there was a significant increase in serum MDA concentration, predicting lipid peroxidation, in group 2 when compared to groups 1, 3 and 4 (p < 0.05). There was not a significant difference between Groups 3 and 4 regarding GSH, MDA, SOD, and AOPP levels. Histopathological analysis revealed that NAC administration, either orally or intraperitoneally, leads to a better incisional healing in terms of inflammation, granulation, collagen deposition, reepithelization and neovascularization. Conclusion: The present study supports the hypothesis that NAC administration alleviates the negative effects of radiotherapy on incisional wound healing by means of reducing oxidative stress markers and improving histologic parameters independent of the route of administration.

To investigate the therapeutic effect of double fill nine tastes soup in treating children recurrent respiratory infection (RRTI) and the change of immune function. 77 RRTI patients were randomly selected into observation and control groups. The observation group was treated with Chinese medicine- double fill nine tastes soup,water frying points 2 times oral. The control was treated with transfer factor oral liquid,every 10 mL,2 times daily oral. Treatment periods were both two months. IgA, IgG, IgM and IL-12, TNF-alpha, INF-gamma were detected before and after treatment to assess the clinical effects and the changes of immune factors, meanwhile, a health group was established. Before treatment, compared with the health group, the serum IgA, IgG, IgM, IgE, IL-12, TNF-alpha, IFN-gamma in both groups were significantly different (P < 0.01). After treatment, the ratio of IgA, IgG, Ig M, IL-12, TNF-alpha, IFN-gamma in two groups were significantly different (P < 0.01). Compared with the recurrence rate and clinical effects, the observation group was better than control, and the differences were significant (P < 0.01). Double fill nine tastes soup has significant effects in treating recurrent respiratory infection (RRI) and enhance the immune function in children.

The chemopreventive effects of curcumin and green tea catechins individually and in combination on 1,2-dimethylhydrazine (DMH)-induced colon carcinogenesis were studied in male Wister rats following 32 weeks of dietary treatment. The incidence, number and size of colorectal cancer were measured. Colorectal aberrant crypt foci (ACF) were analyzed by methylene blue staining. Proliferation indices and apoptotic indices were determined by PCNA immunostaining and TUNEL assay, respectively. The results showed that dietary curcumin, catechins and combination administration significantly inhibited the total number of ACF per rat. The combination treatment displayed the most potent inhibitory effect, while there was no difference of inhibition between curcumin and catechins-treated groups. The incidence of colorectal cancer in the treated groups was significantly lower than that of positive control group. Compared with the positive control group, the proliferation index was significantly decreased and the apoptotic index was significantly increased in all treatment groups, while the effect of the combination was the greatest among the treated groups. Our findings suggest that the combination of curcumin and catechins may produce a synergistic colon cancer-preventative effect that would be more potent than each of the compounds alone.

Boric acid (BA) has positive effects on bone tissue. In this study, the effects of BA on fracture healing were evaluated in an animal model. Standard closed femoral shaft fractures were created in 40 male Sprague-Dawley rats under general anesthesia. The rats were allocated into five groups (n = 8 each): group 1, control with no BA; groups 2 and 3, oral BA at doses of 4 and 8 mg/kg/day, respectively; group 4, local BA (8 mg/kg); and group 5, both oral and local BA (8 mg/kg/day orally and 8 mg/kg locally). After closed fracture creation, the fracture line was opened with a mini-incision, and BA was locally administered to the fracture area in groups 4 and 5. In groups 2, 3, and 5, BA was administered by gastric gavage daily until sacrifice. The rats were evaluated by clinical, radiological, and histological examinations. The control group (group 1) significantly differed from the local BA-exposed groups (groups 4 and 5) in the clinical evaluation. Front-rear and lateral radiographs revealed significant differences between the local BA-exposed groups and the control and other groups (p < 0.05). Clinical and radiological evaluations demonstrated adequate agreement between observers. The average histological scores significantly differed across groups (p = 0.007) and were significantly higher in groups 4 and 5 which were the local BA (8 mg/kg) and both oral and local BA (8 mg/kg/day orally and 8 mg/kg locally), respectively, compared to the controls. This study suggests that BA may be useful in fracture healing. Further research is required to demonstrate the most effective local dosage and possible use of BA-coated implants.

The present study was designed to compare the effects of nano red selenium and sodium selenite on the antioxidative activities of neutrophils and the hematological parameters in sheep. Fifteen sheep were randomly allocated into three groups. Groups 1 and 2 received selenium nanoparticles orally at 1 mg/kg and sodium selenite at 1 mg Se/kg for 10 consecutive days; group 3 served as the control. To assess the degrees of oxidative stress and of lipid peroxidation of the cellular membranes, the levels of thiobarbituric acid reactive substances (TBARS) were determined in serum samples that were collected at different supplementation intervals, i.e., after 0, 10, 20, and 30 days. In addition, hematological parameters in the serum samples were measured by routine procedures. It was found that TBARS levels in groups 1 and 2 were significantly higher on days 20 and 30 compared to the basal level on day 0. It was also found that on day 30, the TBARS activities in both treated groups were significantly higher than those of the controls (P < 0.05). These findings may explain the seemingly paradoxical effects of supplemental selenium on the indicators of oxidative stress, as the levels of TBARS were generally expected to decrease in the presence of selenium. There were no significant differences between the PCV and RBC values in the three groups. The white blood cell count (WBC) in group 1 showed a significant increase on days 20 and 30 in comparison with the control group. However, in group 2, there was a significant increase of the WBC value just on day 20 in comparison with the control group. Also, there were significant increases of the neutrophil counts and significant decreases of the lymphocyte counts on day 10 in group 1, in comparison with those in group 2 and controls, and on days 20 and 30 in groups 1 and 2 in comparison with those in the control group.

To observe the efficacy of regular or intermittent inhalation of salmeterol/fluticasone propionate (SM/FP) in the treatment of bronchial asthma and its effects on growth and development in children. A total of 112 children diagnosed with bronchial asthma between September 2012 and October 2013 were assigned to standardized treatment (standard group, n=56) and non-standardized treatment (intermittent group, n=56). Comparisons of clinical symptom scores and main pulmonary function indicators between the two groups were carried out before treatment and at 6 and 12 months after treatment. The growth velocity and changes in body mass index (BMI) were observed in the two groups. At 6 and 12 months after the treatment, the standard group had significantly reduced clinical symptom scores and significantly increased pulmonary function indicators (percentage of predicted peak expiratory flow, PEF%; percentage of forced expiratory volume in 1 second, FEV1%) (P<0.05); the intermittent group had significantly reduced clinical symptom scores and significantly increased FEV1% (P<0.05), but PEF% was significantly increased only at 6 months after treatment (P<0.05). At 12 months after treatment, the standard group had significantly lower clinical symptom scores and significantly higher PEF% and FEV1% when compared with the intermittent group (P<0.05). The growth velocity and BMI showed no significant differences between the two groups at 6 and 12 months after treatment (P>0.05). Compared with intermittent inhalation, long-term regular inhalation of SM/FP performs better in controlling clinical symptoms and enhancing pulmonary function in children with asthma. Inhalation of SM/FP for one year reveals no apparent effect on the growth and development of these children.

Postoperative face-down posturing (FDP) is recommended to optimize the effects of intraocular gas tamponade after vitrectomy. However, patients undergoing FDP usually experience physical and psychological burdens. This 3-armed, randomized, single-center trial investigated the effects of aromatherapy on FDP-related physical pain. Sixty-three patients under FDP were randomly allocated to one of three treatment groups: aromatherapy massage with essential oil (AT), oil massage without essential oil (OT), and a control group. The AT and OT groups received 10 minutes of massage by ward nurses trained by an aromatherapist, while the control group received usual care. Outcomes were assessed as short-term (pre- to post-intervention) and long-term (first to third postoperative day) changes in physical pain in five body regions using face-scale. The AT and OT groups both revealed similar short-term pain reductions after intervention, compared with the control group. Regarding long-term effects, neither group experienced significant effects until the second day. Significantly more pain reduction compared with usual care occurred on the third day, mainly in the AT group, though there were few significant differences between the AT and OT groups. In conclusion, this study suggests that simple oil massage is an effective strategy for immediate pain reduction in patients undergoing FDP, while aromatherapy may have a long-term effect on pain reduction.

AIM: To evaluate the effects of ursodeoxycholic acid (UDCA) and/or low-calorie diet (LCD) on a rat model of nonalcoholic steatohepatitis (NASH). METHODS: Fifty-five Sprague-Dawley rats were divided into five groups. The control group (n = 9) was fed with standard rat diet for 12 wk, NASH group (n = 10) was fed with high-fat diet consisted of normal diet, 10% lard oil and 2% cholesterol for 12 wk, UDCA group (n = 10) was fed with high-fat diet supplemented with UDCA at a dose of 25 mg/(kg·d) in drinking water for 12 wk, LCD group (n = 10) was fed with high-fat diet for 10 wk and then LCD for 2 wk, and UDCA+LCD group (n = 15) was fed with high-fat diet for 10 wk, followed by LCD+UDCA for 2 wk. At the end of the experiment, body weight, serum biochemical index, and hepatopathologic changes were examined. RESULTS: Compared with the control group, rats in the NASH group had significantly increased body weight, liver weight, and serum lipid and aminotransferase levels. All rats in the NASH group developed steatohepatitis, as determined by their liver histology. Compared with the NASH group, there were no significant changes in body weight, liver weight, blood biochemical index, the degree of hepatic steatosis, and histological activity index (HAI) score in the UDCA group; however, body and liver weights were significantly decreased, and the degree of steatosis was markedly improved in rats of both the LCD group and the UDCA+LCD group, but significant improvement with regard to serum lipid variables and hepatic inflammatory changes were seen only in rats of the UDCA+LCD group, and not in the LCD group. CONCLUSION: LCD might play a role in the treatment of obesity and hepatic steatosis in rats, but it exerts no significant effect on both serum lipid disorders and hepatic inflammatory changes. UDCA may enhance the therapeutic effects of LCD on steatohepatitis accompanied by obesity and hyperl-ipidemia. However, UDCA alone is not effective in the prevention of steatohepatitis induced by high-fat diet. PMID:15818751

Letrozole and norethisterone acetate versus letrozole and triptorelin in the treatment of endometriosis related pain symptoms: a randomized controlled trial

PubMed Central

2011-01-01

Background When aromatase inhibitors are used to treat premenopausal women with endometriosis, additional drugs should be used to effectively down-regulate gonadal estrogen biosynthesis. This randomized prospective open-label study compared the efficacy in treating pain symptoms and the tolerability of letrozole combined with either norethisterone acetate or triptorelin. Methods Women with pain symptoms caused by rectovaginal endometriosis were treated with letrozole (2.5 mg/day) and were randomized to also receive either oral norethisterone acetate (2.5 mg/day; group N) or intramuscular injection of triptorelin (11.25 mg every 3 months; group T). The scheduled length of treatment was 6 months. A visual analogue scale and a multidimensional categorical rating scale were used to assess the severity of pain symptoms. The volume of the endometriotic nodules was estimated by ultrasonography using virtual organ computer-aided analysis. Adverse effects of treatment were recorded. Results A total of 35 women were randomized between the two treatment protocols. Significantly more patients in group N rated their treatment as satisfactory or very satisfactory (64.7%) as compared to group T (22.2%; p = 0.028). The intensity of both non-menstrual pelvic pain and deep dyspareunia significantly decreased during treatment in both study groups, though no statistically meaningful difference between the two groups was apparent. Reduction in the volume of endometriotic nodules was significantly greater in group T than in group N. Interruption of treatment due to adverse effects significantly differed between the groups, with 8 women in group T (44.4%) and 1 woman in group N (5.9%) interrupting treatment (p = 0.018). Similarly, 14 women included in group T (77.8%) and 6 women included in group N (35.3%) experienced adverse effects of treatment (p = 0.018). During treatment, mineral bone density significantly decreased in group T but not in group N. Conclusions Aromatase inhibitors reduce the intensity of endometriosis-related pain symptoms. Combining letrozole with oral norethisterone acetate was associated with a lower incidence of adverse effects and a lower discontinuation rate than combining letrozole with triptorelin.

The sacroiliac joints have complicated biomechanics. While the movements in the joints are small, they exert a significant effect on gait. This study aimed to assess how sacroiliac joint manipulation influences selected gait parameters. The study enrolled 57 healthy subjects. The experimental group consisted of 26 participants diagnosed with dysfunction of one sacroiliac joint. The control group was composed of 31 persons. All subjects from the experimental group underwent sacroiliac joint manipulation. The experimental group showed significant lengthening of the step on both sides and the stride length in this group increased as well. Moreover, the duration of the stride increased (p=0.000826). The maximum midfoot pressure was higher and maximum heel pressure decreased. The differences were statistically significant. 1. Subclinical dysfunctions of the sacroiliac joints may cause functional gait disturbance. 2. Manipulation of the iliosacral joint exerts a significant effect on gait parameters, which may lead to improved gait economy and effec-tiveness. 3. Following manipulation of one iliosacral joint, altered gait parameters are noted on both the manipulated side and the contralateral side, which may translate into improved quality of locomotion.

The present study aimed to investigate the toxic effect of aflatoxin B1 (AFB1) and the effectiveness of a biological mycotoxin binder (Nutritox ® ) in detoxifying aflatoxicosis. Ninety one-day-old chicks were chosen and divided into 3 groups. The first group received standard basal diet only, the second group received a basal diet with AFB1 (0.25 mg/kg diet), and the third group received a basal diet with AFB1 (0.25 mg/kg diet) and Nutritox ® (1 kg/ton diet). AFB1 feed contamination significantly reduced growth performance and deteriorated FCR. Moreover, it significantly increased serum AST, ALT, and malondialdehyde and significantly decreased serum total protein, albumin, globulin, SOD, CAT activities and glutathione peroxidase gene expression as well. Aflatoxin residues were detected in the liver tissues. Furthermore, the liver and kidney of AFB1 treated group showed pathological changes. The supplementation of Nutritox ® significantly reduced aflatoxin levels in the liver and counteracted the negative effects of AFB1. Copyright © 2018 Elsevier B.V. All rights reserved.

Cyclophosphamide (CTX) can attack tumour cells, but can also damage the other cells and microstructures of an organism at different levels, such as haematopoietic cells, liver cells, peripheral lymphocyte DNA, and genetic materials. Low dose radiation (LDR) can induce general adaptation reaction. In this study, we explore the effects of low dose radiation on hepatic damage and genetic material damage caused by CTX. Mice were implanted subcutaneously with S180 cells in the left groin (control group excluded). On days 8 and 11, mice of the LDR and LDR+CTX groups were given 75 mGy of whole-body γ-irradiation; whereas mice of the CTX and LDR+CTX groups were injected intraperitoneally with 3.0 mg of CTX. All mice were sacrificed on day 13. DNA damage of the peripheral lymphocytes, alanine aminotransferase (ALT) activity, total protein (TP), albumin (ALB) of the plasma, malonyl-dialdheyde (MDA) content, superoxide dismutase (SOD) and glutathione peroxidase (GSH-PX) activity of the hepatic homogenate, and micronucleus frequency (MNF) of polychromatoerythrocytes in the bone marrow were analysed. The control group had the lowest MDA content and the highest SOD and GSH-PX activity, whereas the CTX group had the highest MDA content and the lowest SOD and GSH-PX activity. Compared with the CTX group, the MDA content decreased significantly (p < 0.01) and the SOD and GSH-PX activity increased significantly (p < 0.05) in the LDR+CTX group. TP and ALB in control group were higher than that of the other groups. Compared with the sham-irradiated group, TP and ALB in the LDR group elevated significantly (p < 0.05). The control group had the lightest DNA damage, whereas the CTX group had the severest. DNA damage in LDR+CTX group was much lighter compared with that of the CTX group (p < 0.05). MNF in the CTX group increased significantly compared with the control and the sham-irradiated groups (p < 0.01). Compared with the CTX group, MNF in LDR+CTX group had a tendency of decline, but without statistical significance (p > 0.05). Pre-chemotherapeutic LDR can induce the activities of anti-oxidative enzymes and promote the elimination of free radicles to alleviate the damaging effects of oxidative stress to hepatic tissue caused by high-dose CTX. At the same time, LDR has no obvious effect on the ALT activity of plasma, but may have protective effect on the protein synthesis function of the liver. High-dose CTX chemotherapy can cause DNA damage of peripheral lymphocytes; however, LDR before chemotherapy may have certain protective effect on DNA damage. Moreover, CTX has potent mutagenic effect; however, LDR may have no protective effect against the genetic toxicity of CTX chemotherapy.

To investigate the effects of micro-encapsulated bifidobacteria on gut barrier and bacterial translocation after hemorrhagic shock and resuscitation. Sprague-Dawley rats were divided into 6 groups: PBS+sham shock group fed with PBS for 7 days and then undergoing sham shock, bifidobacteria+sham shock group fed with bifidobacteria (10(9) cfu/d) for 7 days and then undergoing sham shock, micro-encapsulated bifidobacteria+sham shock group, fed with micro-encapsulated bifidobacteria (10(9) cfu/d) for 7 days and then undergoing sham shock, PBS+hemorrhagic shock group fed with PBS for 7 days and then undergoing hemorrhagic shock, bifidobacteria+shock group fed with bifidobacteria for 7 days and then undergoing hemorrhagic shock, and micro-encapsulated bifidobacteria+shock group, fed with micro-encapsulated bifidobacteria for 7 days and then undergoing hemorrhagic shock. Three hours after resuscitation laparotomy was performed, distal cecum was resected to undergo bacteriological analysis of the cecal content, mesenteric lymph nodes (MLNs), a liver lobe, and the middle part of spleen were resected to undergo bacterial culture for bacterial translocation, and the terminal ileum was resected to observe the villous damage. There was no significant difference in the amount of blood loss among the 3 hemorrhagic shock groups. The amounts of aerobes in cecum of the bifidobacteria+shock and micro-encapsulated bifidobacteria+shock groups, especially that of the latter group, were significantly lower than that of the PBS+shock group. The amounts of anaerobes and the amounts of bifidobacteria in cecum of the bifidobacteria+shock group and micro-encapsulated bifidobacteria+shock group, especially those of the latter group, were significantly higher than those of the PBS+shock group. No bacterial translocation to liver was observed in all groups. The magnitudes of total aerobes translocation in spleen of the bifidobacteria+shock and encapsulated bifidobacteria+shock groups were significantly lower than that of the PBS+shock group, however, there were not significant differences in the translocation in the MLN of total aerobes ad bifidobacteria among different groups. The percentage of ileal villous damage of the bifidobacteria+shock and encapsulated bifidobacteria+shock groups were significantly lower than that of the PBS+shock group. Bifidobacteria effectively protects the gut barrier, reduces bacterial translocation from the gut after hemorrhagic shock and resuscitation. And micro-encapsulated Bifidobacteria can enhance those effects further.

Soy isoflavones have been reported to decrease the risk of atherosclerosis in postmenopausal women. However, the effects of dietary consumption of soybean have not been explored. In this study, we evaluated the effects of consuming yellow soybeans, black soybeans (Glycine max), or sword beans (Canavalia gladiate) on lipid and oxidative stress levels in an ovariectomized rat model. Forty-seven nine-week-old female rats were ovariectomized, randomly divided into four groups, and fed one of the following diets for 10 weeks: a diet supplemented with casein (NC, n = 12), a diet supplemented with yellow soybean (YS, n = 12), a diet supplemented with black soybean (BS, n = 12), or a diet supplemented with sword bean (SB, n = 11). Plasma triglyceride (TG) levels in the BS and SB groups were significantly lower than that in the NC group. Notably, the BS group had significantly lower plasma total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) levels than the other groups. Hepatic total lipid levels were significantly lower in the YS and SB groups, and cholesterol levels were significantly lower in the SB group than in the NC group. Superoxide dismutase (SOD) and catalase (CAT) activities were significantly higher in the groups fed beans compared to the NC group. Hepatic thiobarbituric acid reactive substances (TBARS) levels were also significantly lower in the BS and SB groups than the NC group. In conclusion, our results suggest that consumption of various types of beans may inhibit oxidative stress in postmenopausal women by increasing antioxidant activity and improving lipid profiles. Notably, intake of black soybean resulted in the greatest improvement in risk factors associated with cardiovascular disease.

Sway and postural instability have drawn attention as a risk factor for osteoporotic fracture, in addition to low bone mineral density (BMD) and poor bone quality. In view of the fracture-reducing effect of alfacalcidol and active absorbable algal calcium (AAA Ca) not readily explained by rather mild increases of BMD, attempts were made to evaluate postural stabilizing effect of alfacalcidol, AAA Ca, and calcium carbonate (CaCO(3)) by computerized posturography. Track of the gravity center was analyzed to calculate parameters related to tract length, track range, and track density to express the degree of sway before and after supplementation in 126 subjects ranging in age between 20 and 81 years randomly divided into four groups. Supplementation with AAA Ca containing 900 mg elemental Ca (group A), no calcium (group B), CaCO(3) also containing 900 mg elemental Ca (group C), or alfacalcidol (group D) continued daily for 12 months. For each parameter, the ratio closed eye value/open eye value (Romberg ratio) was calculated to detect aggravation of sway by eye closure. Age, parameters of Ca and P, and proportions of subjects with fracture and those with low BMD showed no marked deviation among the groups. With eyes open, significant decreases of a track range parameter (REC) from group B was noted in groups A (P = 0.0397) and D (P = 0.0296), but not in group C according to multiple comparison by Scheffe, indicating superior postural stabilizing effect of A and D over C. In the first 2 months, a significant fall was already evident in REC from group B in group D (P = 0.0120) with eyes open. Paired comparison of sway parameters before and after supplementation revealed a significant increase of track density parameter (LNGA), indicating sway control efficiency and a significant decrease of REC in groups A and D compared to group B with eyes open. With eyes closed, only group A showed a significant improvement from group B (P = 0.0456; Fig. 1), with a significant shortening on paired After/Before comparison (P = 0.0142; Fig. 2). Computerized posturography appears to be useful in analyzing sway phenomena especially as to the effects of vitamin D and various Ca preparations.

Acne vulgaris is a chronic inflammatory disease of the pilosebaceous follicles and one of the most common skin diseases. The peeling method has been recently found to be effective for acne treatment. This study aimed to compare the efficacy of pyruvic acid 50% and salicylic acid 30% peeling in the treatment of mild to moderate acne. In a prospective single-blinded clinical trial, 86 patients with acne were randomly assigned into two groups. In both groups, the routine treatment of acne (topical solution of erythromycin 4%, triclorocarban soap, and sunscreen) were used twice a day for 8 weeks. In addition, salicylic acid 30% for the control group and pyruvic acid 50% for the case group were used. In both groups, acne severity index (ASI) was calculated before and at week 2, 4, 6, and 8 of the treatment. Patient satisfaction was assessed at the end of the treatment. Side effects were recorded using a checklist. In both groups, the reduction in the number of comedones, papules, and ASI were statistically significant ( P < 0.001) in the course of treatment. However, it was not significant regarding the number of pustules ( P = 0.09). None of the number of comedone, papules, pustules, and ASI was statistically different between study groups. Both treatment groups had similar side effects except for scaling in the fifth session, which was significantly lower in salicylic acid - treated patients ( P = 0.015). Both pyruvic acid 50% and salicylic acid 30% are effective in the improvement of mild to moderate acne with no significant difference in efficacy and side effects.

Aim. To investigate the effect of daikenchuto (TJ-100; DKT) for ulcerative colitis (UC) model mouse and assess its anti-inflammatory mechanisms. Methods. We evaluated the effects of DKT on dextran sulfate sodium- (DSS-) induced experimental colitis. First, we assessed the short-term effects of DKT using two groups: 5% DSS group and 5% DSS with DKT group. Colon length; histological scores; and interleukin- (IL-) 10, IL-1β, and tumor necrosis factor-α mRNA expression profiles were analyzed using real-time PCR. Second, we assessed the long-term effects of DKT, by comparing survival time between 2% DSS and 2% DSS with DKT groups. Results. After 7 days, the colon lengths of DSS + DKT group were longer than those of the DSS group (mean values: 6.11 versus 5.69 cm, p < 0.05). Furthermore, compared to DSS group, the DSS + DKT group maintained significantly higher levels of serum hemoglobin (13.1 versus 10.7 g/dL, p < 0.05) and exhibited significantly higher expression levels of IL-10 (p < 0.05). The 2% DSS + DKT group exhibited significantly longer survival time than the 2% DSS group (70 versus 44 days, p < 0.01). Conclusion. Our results indicate that DKT prevented inflammation in the colon, indicating its potential as a new therapeutic agent for UC. PMID:28210268

To examine the effects of music intervention on the physiological stress response and the anxiety level among mechanically ventilated patients in intensive care unit. Despite the fact that previous studies have found music interventions to be effective in stress and anxiety reduction, effects of music on the Chinese population are inconclusive and warranted systematic study to evaluate its effect fully for a different Asian culture. A randomised placebo-controlled trial. A total of 137 patients receiving mechanical ventilation were randomly assigned to either music listening group, headphone group or control group. Outcome measures included the Chinese version of Spielberger State-Trait Anxiety Scale and physiological parameters (heart rate, respiratory rate, saturation of oxygen and blood pressure). Comparison of mean differences (pretest score-posttest score) showed significant differences in heart rate, respiratory rate, systolic blood pressure and diastolic blood pressure as well as the Chinese version of Spielberger State-Trait Anxiety Scale, but not in SaO(2) among the three groups (ranging from p < 0.001 to p = 0.007), of which greater mean differences were found in music listening group. A significant reduction in physiological stress response (heart rate and respiratory rate) over time was found in music listening group (p < 0.001 for both variables) and a significant increase in heart rate and respiratory rate over time in control group (p < 0.001 and p = 0.032), with no significant change over time in headphone group. Within group pretest-posttest comparison of the Chinese version of Spielberger State-Trait Anxiety Scale demonstrated a significant reduction in anxiety for the music listening group (p < 0.001) and headphone group (p < 0.001) but not the control group. Our findings confirm that short-term therapeutic effects of music listening results in substantial reduction in physiological stress responses arising from anxiety in mechanically ventilated patients. Music as a non-pharmacological nursing intervention can be used as complementary adjunct in the care of patients with low-energy states who tire easily, such as those requiring mechanical ventilator support.

The public awareness about cell phone safety increased greatly in the last few years as various reports of potential adverse health effects on humans exposed to radiations emitted from cellular phones were published. The aim of the study was to assess the effect of long term cell phone exposure on physiological and hematological parameters along with its impact on serum lipid profiles and a single call effect on heart rate, blood pressure and SpO2(%) of healthy male medical students. The students were divided into two groups, group I (n=22, age 20.63 +/- 1.17 yrs) comprising first year medical students who were never exposed to cell phones at the time of this study and group II (n=35, age 22.00 +/- 1.56 yrs) consists of final year (fourth year) male medical students who were using cell phone for more than four years before this study. The results showed no significant differences the groups in basal heart rate, systolic blood pressure, SpO2(%), or various hematologic parameters. Acute exposure (single call of cell phone with 900 MHz for 1 minute) in both groups showed a significant increase in peak heart rate in group II as compared with group I and a significant decrease in peak SpO2 (%) in group I as compared with group II. Serum total cholesterol, VLDL-cholesterol, and triglycerides concentration were significantly higher in group II (long term cell phone exposed) than in group I, suggesting a mild alteration of lipid profile among group II subjects.

We evaluated the effect of oral usage of honey and pollen, either separately or together, on postoperative intraabdominal adhesions. Forty rats were randomly separated into 4 groups of 10 rats each. Abrasion was performed on the cecum, and a patch of peritoneum located opposite to the cecal abrasion was completely dissected. Group 1 rats received no treatment; Group 2 rats received 4 g/kg/day honey; Group 3 rats received 4 g/kg/day pollen; and Group 4 rats received 4 g/kg/day honey and pollen mixed in equal amounts, in addition to the standard feeding for postoperative 21 days. All the rats were sacrificed on the 21st day. Following the adhesion scoring, tissue specimens of the peritoneum and bowel were subjected to histopathological investigation. The tissue and blood specimens were also taken for biochemical analysis to investigate the antioxidant capacity. Adhesion scores were significantly different between the control and other groups. No dense adhesion was observed in the treatment groups. Tissue malondialdehyde levels were significantly different between the control and honey and honey+pollen groups. Superoxide dismutase and glutathione-peroxidase levels were significantly different between the control and other groups. Catalase levels were different between the control and honey groups. Plasma antioxidant levels were different between the control and other groups. The pathological scores for fibrosis and inflammation were significantly different between the control and other groups. Honey and pollen were found to be effective in preventing postoperative intraabdominal adhesions, and these effects were thought to be a result of their antiinflammatory and antioxidant properties.

Background: Numerous scientific studies have reported beneficial physiological changes after short- and long-term yoga training. Suryanamaskar (SN) is an integral part of modern yoga training and may be performed either in a slow or rapid manner. As there are few studies on SN, we conducted this study to determine the differential effect of 6 months training in the fast and slow versions. Materials and Methods: 42 school children in the age group of 12–16 years were randomly divided into two groups of 21 each. Group I and Group II received 6 months training in performance of slow suryanamaskar (SSN) and fast suryanamaskar (FSN), respectively. Results: Training in SSN produced a significant decrease in diastolic pressure. In contrast, training in FSN produced a significant increase in systolic pressure. Although there was a highly significant increase in isometric hand grip (IHG) strength and hand grip endurance (HGE) in both the groups, the increase in HGE in FSN group was significantly more than in SSN group. Pulmonary function tests showed improvements in both the groups though intergroup comparison showed no significance difference. Maximum inspiratory pressure (MIP) and maximum expiratory pressure increased significantly in both the groups with increase of MIP in FSN group being more significant than in SSN. Conclusion: The present study reports that SN has positive physiological benefits as evidenced by improvement of pulmonary function, respiratory pressures, hand grip strength and endurance, and resting cardiovascular parameters. It also demonstrates the differences between SN training when performed in a slow and fast manner, concluding that the effects of FSN are similar to physical aerobic exercises, whereas the effects of SSN are similar to those of yoga training.

To investigate the effect of metronomic chemotherapy of low dose phosphoramide combined with prednisolone (CP metronomic chemotherapy) on proliferation and apoptosis of RPMI 8226 cells, and to explore its regulating effect on Notch1/NF-κB signaling pathways. Experiment was divided into the DMSO control group, and the phosphoramide mustard (PM) group, the prednisolone group, the phosphoramide mustard plus prednisolone group (the CP group). RPMI 8226 cells were treated with different drugs, CCK-8 method was used to detect cell proliferation, flow cytometry was used to detect the cell cycle and apoptosis, reverse transcription PCR was used to detect Notch1 and NF-κB mRNA expression level. Compared with DMSO control group, RPMI8226 cell proliferation inhibition rate in all the PM, prednisolone and CP groups increased significantly with prolonging of time (r of 0.994,0.996,0.999, respectively, P<0.001). And at the same time, the inhibitory rate of cell proliferation was significantly different; the cell inhibitory rate in PM group was lowest, that in CP group was highgest, that in prednissone group was intermediate (P<0.01). After 48 hours, compared with the DMSO control group, the G 1 /G 0 cell proportion in treatment group increased significantly, S phase cell proportion decreased significantly, especially in PM and CP groups. The G 2 /M phase cell proportion increased in PM group, while reduced in the prednisolone and the CP groups. After 48 hours, compared with the DMSO control group, RPMI 8226 cell apoptosis rate increased as follow: in PM, pre-dnisolone and CP group(P<0.01). After 48 hours, compared with the DMSO control group, Notch1 and NF-κB mRNA expression in the prednisolone, the PM and the CP group decreased significantly(P<0.001). CP metronomic chemotherapy can significantly reduce RPMI 8226 cell proliferation, promote RPMI 8226 cell apoptosis, arrest RPMI 8226 cells mainly in the G 1 /G 0 phase, and significantly reduce Notch1 and NF-κB expression levels. It is suggested that Notch1/NF-κB signaling pathways is involved in CP metronomic chemotherapy for MM.

To investigate the correlation effects between single or combined administration of Calculus Bovis or zolpidem and changes of inhibitive neurotransmitter in rat striatum corpora. Sampling from rat striatum corpora was carried out through microdialysis. The content of two inhibitive neurotransmitters in rat corpus striatum- glycine (Gly) and gama aminobutyric acid (GABA), was determined by HPLC, which involved pre-column derivation with orthophthaladehyde, reversed-phase gradient elution and fluorescence detection. GABA content of rat striatum corpora in Calculus Bovis group was significantly increased compared with saline group (P < 0.01). GABA content of zolpidem group and Calculus Boris plus zolpidem group were increased largely compared with saline group as well (P < 0.05). GABA content of Calculus Bovis group was higher than combination group (P < 0.05). GABA content of zolpidem group was not significantly different from combination group. Gly content of Calculus Bovis or zolpidem group was markedly increased compared with saline group or combination group (P < 0.05). Contents of two inhibitive neurotransmitters in rat striatum corpora were all significantly increased in Calculus Bovis group, zolpidem group and combination group. The magnitude of increase was lower in combination group than in Calculus Bovis group and Zolpidem group, suggesting that Calculus Bovis promoted encephalon inhibition is more powerful than zolpidem. The increase in two inhibitive neurotransmitters did not show reinforcing effect in combination group, suggesting that Calculus Bovis and zolpidem may compete the same receptors. Therefore, combination of Calculus Bovis containing drugs and zolpidem has no clinical significance. Calculus Bovis shouldn't as an aperture-opening drugs be used for resuscitation therapy.

Objective Vitamin K2 (menatetrenone) is an effective treatment for patients with postmenopausal osteoporosis. We herein performed a subanalysis of patients with systemic autoimmune diseases undergoing glucocorticoid therapy in our previous prospective study. Methods Sixty patients were categorized into a group with vitamin K2 treatment (n=20, Group A) and a group without vitamin K2 treatment (n=40, Group B). All patients were treated with bisphosphonates. Results Serum levels of osteocalcin and undercarboxylated osteocalcin decreased significantly after the start of glucocorticoid therapy in both groups, while the serum osteocalcin level was significantly higher in Group A than Group B during the third (p=0.0250) and fourth weeks (p=0.0155). The serum level of the N-terminal peptide of type I procollagen, a bone formation marker, decreased during glucocorticoid therapy, but was significantly higher in Group A than Group B during the fourth week (p=0.0400). The bone mineral density and fracture rate showed no significant differences between the two groups. Conclusion Although vitamin K2 improves bone turnover markers in patients with osteoporosis on glucocorticoid therapy, it has no significant effect on the bone mineral density and fracture rate after 1.5 years of treatment.

To investigate the effects of exercise preconditioning on oxidative injury in the intestinal tissue of rats. Sixty male Wistar rats were randomly divided into six groups as sham (n = 10), ischemia-reperfusion (n = 10), exercise (n = 10), exercise plus ischemia-reperfusion (n = 10), ischemic preconditioning (n = 10), and ischemic preconditioning plus ischemia-reperfusion groups (n = 10). Tissue levels of malondialdehyde and activities of myeloperoxidase and superoxide dismutase, and serum levels of tumor necrosis factor-alpha and interleukin-6 were measured. Intestinal tissue histopathology was also evaluated by light microscopy. Tumor necrosis factor-alpha concentrations significantly decreased in the exercise group compared to the sham group (p < 0.05). Myeloperoxidase activity significantly increased and superoxide dismutase activity significantly decreased in ischemia-reperfusion group compared to the sham group (p < 0.05). Superoxide dismutase activity in the ischemic preconditioning and ischemic preconditioning plus ischemia-reperfusion groups were significantly higher compared to the ischemia-reperfusion and exercise groups (p < 0.05). Histopathologically, intestinal injury significantly attenuated in the exercise plus ischemia-reperfusion group compared to the ischemia-reperfusion group. The results of the present study indicate that exercise training seems to have a protective role against intestinal ischemia-reperfusion injury (Tab. 3, Fig. 1, Ref. 35).

This 2-week interventional study involved a randomized allocation of subjects into three groups: Group A (daily ingestion of 350 g vegetables cooked without water using multi-ply [multilayer-structured] cookware), Group B (daily ingestion of 350 g vegetables; ordinary cookware) and Group C (routine living). Before and after intervention, each subject underwent health examination with 24-h urine sampling. Blood vitamin C significantly increased after intervention from the baseline in Group A (P < 0.01) and Group B (P < 0.05). β-Carotene levels also increased significantly after intervention in Group A (P < 0.01) and Group B (P < 0.01). Oxidized low-density lipoprotein decreased significantly after intervention in Group A (P < 0.01). In Group A, 24-h urinary potassium excretion increased significantly (P < 0.01) and 24-h urinary sodium (Na)/K ratio improved significantly (P < 0.05) after intervention. In conclusion, a cooking method modification with multi-ply cookware improved absorption of nutrients from vegetables and enhanced effective utilization of the antioxidant potentials of vegetable nutrients.

To study a non-drug therapy for hypertension disease by combining percutaneous laser and electric pulse stimulation to acupoint with music, and to test the efficiency of the combining treatment to grade 1 essential hypertension. A total of 174 patients with grade 1 essential hypertension were randomly assigned to 3 groups with a random number table after Chinese medicine (CM) syndrome differentiation: the photoelectric and musical treatment group (Group 1, with a self-developed multi-mode audio frequency pulse photoelectric therapeutic apparatus), acupuncture group (Group 2), and oral placebo group (Group 3), 58 cases per group. The curative effect of each group was evaluated by the changes of blood pressure and CM syndrome integral before and after treatment. Compared with Group 3, there were significant decrease of blood pressure and CM syndrome integral in Group 1 and Group 2 (P<0.01). Compared with Group 2, Group 1 showed the highest decrease in systolic pressure (P<0.017). The total effective rate of anti-hypertension in Group 1 (91.38%, 53/58) was significantly higher than that in Group 2 (74.13%, 43/58) and Group 3 (18.97%, 11/58, P<0.05 or P<0.01); and that in Group 2 was also significantly higher than that in Group 3 (P<0.01). There were significant difference in the total effective rate of CM syndrome integral in both Group 1 (93.10%, 54/58) and Group 2 (84.48%, 49/58) as compared with Group 3 (17.24%, 10/58, P<0.01), while there was no significant difference between Group 1 and Group 2 (P>0.05). The multi-mode audio frequency pulse photoelectric therapeutic apparatus, combining music, laser and electric pulse stimulation, is clinically useful for grade 1 essential hypertension. This "three in one" therapy method is non-invasive, easy and simple to handle. It is expected to be popularized as a new alternative treatment.

The purpose of the study was to determine if six weeks of plyometric training can improve an athlete's agility. Subjects were divided into two groups, a plyometric training and a control group. The plyometric training group performed in a six week plyometric training program and the control group did not perform any plyometric training techniques. All subjects participated in two agility tests: T-test and Illinois Agility Test, and a force plate test for ground reaction times both pre and post testing. Univariate ANCOVAs were conducted to analyze the change scores (post - pre) in the independent variables by group (training or control) with pre scores as covariates. The Univariate ANCOVA revealed a significant group effect F2,26 = 25.42, p=0.0000 for the T-test agility measure. For the Illinois Agility test, a significant group effect F2,26 = 27.24, p = 0.000 was also found. The plyometric training group had quicker posttest times compared to the control group for the agility tests. A significant group effect F2,26 = 7.81, p = 0.002 was found for the Force Plate test. The plyometric training group reduced time on the ground on the posttest compared to the control group. The results of this study show that plyometric training can be an effective training technique to improve an athlete's agility. Key Points Plyometric training can enhance agility of athletes. 6 weeks of plyometric training is sufficient to see agility results. Ground reaction times are decreased with plyometric training PMID:24353464

The magnesium (Mg) and manganese (Mn) were evaluated for its effectiveness as an immunomodulator in rats. The treatments were as follows: Group 1, AIN-93M diet (0.05% Mg, 0.001% Mn); Group 2, high-dose Mg (0.1% Mg, 0.001% Mn); and Group 3, high dose Mn (0.05% Mg, 0.01% Mn) (n-12/group). After 12 weeks of supplementation, rats were sacrificed to assess the effect on a range of innate responses (tumoricidal activity, oxidative burst and nitric oxide) and the mitogen-stimulated lymphoproliferative response. Immune function was significantly affected in both the high dose Mg and the Mn group. Lymphocyte proliferative responses and NK cell activity were measured in pooled spleen from each group. The mitogen response of lymphocytes to LPS in the spleen was significantly reduced in high dose Mg-treated groups, whereas the response to ConA was not affected in both high dose minerals-treated groups. The reactive oxygen species level of macrophages was decreased in both groups. These effects were more pronounced in high dose Mg-treated group. Nitric oxide production was also decreased in high dose minerals-treated group. In addition, tumoricidal activities of splenic NK cell and peritoneal macrophage in mineral exposed rats were significantly increased. Moreover, percent death of macrophage was reduced in two groups receiving high dose mineral supplements. Taken together, the present data suggest that high dose trace min erals exert a differential effect on the function of immune cells.

Aim of this study was the training effect evaluation on the Special Aviation Gymnastics Instruments (SAGI) on blood metallothionein (MT), zinc (Zn), copper (Cu), protein, neuron-specific enolase (NSE), and physical fitness in the examined cadets. The study comprised 55 cadets, aged 20, divided into two groups: examined group A (N=41) and control group B (N=14). In both groups, blood material was collected twice, i.e. before (baseline) and after training (series I), during (series II), and after completion of training on the SAGI (Series III). Blood serum MT, Zn, Cu, protein, and NSE were assayed with commercially available kits). Physical fitness was assessed with commonly used fitness tests. A significant decrease in serum MT was noted in both groups in all three series of assays after training, except group B in series II. NSE significantly increased in group A in series II after training. NSE activity increased significantly in group B in series I and III. In both groups, a significant decrease in blood serum Zn was noted after training in series I and II. Serum Cu significantly decreased in group A in all three series of assays. Blood serum protein significantly decreased in group A in series III. In series II, blood serum protein increased significantly in both groups. The remaining values were not changed significantly. Training intensity on SAGI lowered serum MT levels after training in comparison with the control group. This might be associated with Zn, Cu, and protein metabolism.

Baicalin had neuroprotective effects on inhibiting neuronal cell apoptosis induced by spinal cord ischemic injury. This study aimed to explore the protective effects of Baicalin on rats with spinal cord injury (SCI) and its mechanism of action. The recovery of spinal cord nerve function in rats was evaluated by the Basso, Beattie, and Bresnahan (BBB) score and the combine behavioral score (CBS). The expressions of cytokines tumor necrosis factor α (TNF-α), interleukin-1β (IL-1β), and IL-6 were detected by the enzyme-linked immunosorbent assay method. Expressions of inflammation-related proteins were detected by Western blot. Multivariate statistical analysis was performed for serum metabolites. The BBB and CBS score results showed that Baicalin had a certain improvement on rats with SCI. SCI symptoms were significantly improved in low-dose and high-dose groups. The levels of TNF-α, IL-1β, and IL-6 in the SCI group were significantly increased. The expressions of NF-κB p65, NF-κB p50, p-IκBα, and IKKα in the SCI group showed the opposite trend compared with the low-dose and high-dose groups. Compared with the sham group, glutamine, levels of 3-OH-butyrate, N-acetylaspartate, and glutathione were significantly reduced, and the levels of glutamate and betaine were significantly increased in the SCI group. When Baicalin was administered, the contents of glutamine synthase (GS) and glutaminase (GLS) were significantly reduced, indicating that Baicalin had the effect of improving GS and GLS. Baicalin has protective effects on improving SCI and lower extremity motor function, has a significant anti-inflammatory effect, and regulates the serum metabolic disorder caused by SCI in rats. © 2018 Wiley Periodicals, Inc.

In this retrospective cohort study, we compared the efficacy of extracorporeal shock wave therapy (ESWT) for plantar fasciitis in patients with different activity levels and different pain locations. In total, 92 patients (99 feet) who were over 40 years old with chronic plantar fasciitis were treated with ESWT after being categorized as participating in recreational sports(group R) or only activities of daily living (group D). On the other hand, patients were categorized as having pain in the plantar fascia enthesis (group E) or the entire plantar fascia (group W). Pain during activity and general tenderness were evaluated by using the visual analog scale (VAS) before and after ESWT. Although the VAS for pain score during activity significantly improved in both groups R and D after ESWT (P<0.001 in both groups), the degree of improvement in the VAS for pain score in group R was not significantly different from that in group D (P=0.061 ). The VAS for tenderness score also significantly improved in both groups R and D (P<0.001 in both groups), but there was also no significant difference between the degree of improvement in the VAS for tenderness in group R and that in group D (P=0.41 ). However, the degree of improvement in the VAS for pain and VAS for tenderness scores was significantly greater in group E than that in group W (P<0.001, =0.042 , respectively). We concluded that ESWT was effective for treating plantar fasciitis in middle-aged patients and ESWT was effective in patients not only playing recreational sports but also having activities of daily living. ESWT was more effective in patients with pain in the plantar fascia enthesis than in patients with pain in the entire plantar fascia.

The purpose of this study was to investigate the effects of temperature on chronic trapezius myofascial pain syndrome during dry needling therapy. Sixty patients were randomized into two groups of dry needling (DN) alone (group A) and DN combined with heat therapy group (group B). Each patient was treated once and the therapeutic effect was assessed by the visual analogue scale (VAS), pressure pain threshold (PPT), and the 36-item short form health survey (SF-36) at seven days, one month, and three months after treatment. Evaluation based on VAS and PPT showed that the pain of patients in groups A and B was significantly (P < 0.05) relieved at seven days, one month, and three months after treatment Compared to before treatment. There was significantly (P < 0.05) less pain in group B than group A at one and three months after treatment. The SF-36 evaluation demonstrated that the physical condition of patients in both groups showed significant (P < 0.05) improvement at one month and three months after treatment than before treatment. Our study suggests that both DN and DN heating therapy were effective in the treatment of trapezius MPS, and that DN heating therapy had better long-term effects than DN therapy. PMID:25383083

Objective: To explore the effect of low-dose or standard-dose conjugated equine estrogen (CEE) combined with natural progesterone or dydrogesterone on bone density in menopause syndrome women. Methods: Totally 123 patients with menopause syndrome were recruited and randomly assigned to 3 treatment groups: group A (low-dose CEE+progesterone) , group B (standard-dose CEE+progesterone) , group C (standard-dose CEE+dydrogesterone) . Using continuous sequential regimen, the duration of intervention was 12 cycles. The bone mineral density of lumbar 2-4 and neck of femur, the bone metabolic markers, the level of FSH and estradiol were examined just before the drug administration and 12 months after the beginning of experiment. Results: There were 107 cases completed the one year trial. (1) Bone density: after 12 cycles of treatment, there was no significant change in bone density in group A ( P> 0.05) ; lumbar vertebrae of group B and C increased significantly, at 3.0% and 2.1%respectively (all P< 0.05) . The bone density of left femoral neck of group C significantly increased by 2.9% ( P= 0.029) . There was no significant difference among the treatment groups at the beginning of experiment ( P> 0.05) . (2) Bone metabolic markers: after 12 cycles of treatment, the levels of calcium, phosphorus, alkaline phosphatase, Ca/Cr decreased significantly, the difference were statistically significant (all P< 0.05) . There was no significant difference among the treatment groups at the beginning of experiment ( P> 0.05) . (3) Levels of FSH and estradiol: after 12 cycles of treatment, the levels of FSH in three groups were decreased significantly (all P< 0.01) . The levels of estradiol in three groups were increased significantly (all P< 0.01) . There was no significant difference among the treatment groups at the beginning of experiment ( P> 0.05) . Conclusions: Both low-dose and standard-dose menopause hormone therapy (MHT) could elevate the level of estradiol, reduce bone turnover, prevent bone loss of postmenopausal women effectively. The standard dose of MHT could also increase the density of vertebrae and femoral neck, and generate more clinical benefits.

We aimed to investigate the protective effect of selected treatment agents on liver injury in lipopolysaccharide (LPS)-induced rat sepsis model. The sepsis includes complex inflammatory responses between a microbial pathogen and the host immune system, and leads to organ failure and also death. This study was performed with 29 male Wistar Albino rats. Rats were divided randomly into five groups: Sham group, LPS-treated sepsis group, LPS+thalidomide treated group, LPS+etanercept treated group and LPS+thalidomide+etanercept treated group, respectively. Liver tissue tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β) and interleukin 6 (IL-6) levels were determined by enzyme-linked immuno-sorbent assay (ELISA) method. The expression of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) was performed using western blot analysis. The levels of tissue TNF-α, IL-1β and IL-6 were found statistically significantly higher in sepsis group than in the sham group. TNF-α levels were found statistically significantly decreased in LPS+etanercept and LPS+thalidomide+etanercept treated groups when compared with LPS group (p < 0.05). For IL-1β and IL-6 levels a statistically significant decline was observed in the LPS+thalidomide and LPS+etanercept treated groups compared to the LPS group (p < 0.05). Expression of NF-κB protein in liver tissue was significantly elevated in the LPS group compared to sham group (p < 0.001). In treatment groups, a marked decrease was observed in NF-κB protein expression. The results of this investigation suggested that etanercept and thalidomide administration may have a beneficial effect on LPS-induced sepsis. So, the present study may have significant clinical relevance, but clinical trials are needed to confirm these results (Tab. 1, Fig. 1, Ref. 36).

To explore the antitumor effect of immunotherapy with recombinant Xenopus laevis vascular endothelial growth factor (xVEGF) as a vaccine combined with adriamycin on lymphoma model in mice. EL4 lymphoma model was established in C57BL/6 mice. Mice were randomized into four groups: combination therapy, adriamycin alone, xVEGF alone and normal saline (NS) groups, and then were given relevant treatments. The growth of tumor, the survival rate of tumor-bearing mice, and the potential toxicity of regimens above were observed. Anti-VEGF antibody-producing B cells (APBCs) were detected by enzyme-linked immunospot (ELISPOT) assay. In addition, microvessel density (MVD) of tumor was detected by immunohistochemistry, and tumor cell apoptosis was also detected by TUNEL staining. The tumor volumes of mice were significantly smaller in combination group than those in other three groups (P < 0.05). Complete regression of tumor was observed in 3 of 10 mice in combination group. Forty-eight days after inoculation of tumor cells, the survival rate of mice was significantly higher in combination group than in NS group (P < 0.01). The anti-VEGF APBC count in combination group or xVEGF group was significantly higher, compared with that in adriamycin group or NS group (P < 0.01). MVD in tumor tissues was significantly lower in combination group than those in other three groups (P < 0.05). Moreover, tumor cell apoptosis was significantly higher in combination group than those in other three groups (P < 0.05). In this experimental study, the use of xVEGF vaccine and adriamycin as a combination of immunotherapy with chemotherapy has sucessfully produced synergistic antitumor effect on lymphoma in mice.

Background Neurobehavioral consequences of heavy prenatal alcohol exposure are well documented, however the role of age or sex in these effects has not been studied. The current study examined the effects of prenatal alcohol exposure, sex, and age on neurobehavioral functioning in children. Methods Subjects were 407 youth with prenatal alcohol exposure (n=192) and controls (n=215). Two age groups [child (5–7y) or adolescent (10–16y)] and both sexes were included. All subjects completed standardized neuropsychological testing and caregivers completed parent-report measures of psychopathology and adaptive behavior. Neuropsychological functioning, psychopathology, and adaptive behavior were analyzed with separate 2 (exposure history) × 2 (sex) × 2 (age) MANOVAs. Significant effects were followed by univariate analyses. Results No three-way or two-way interactions were significant. The main effect of group was significant in all three MANOVAs, with the control group performing better than the alcohol-exposed group on all measures. The main effect of age was significant for neuropsychological performance and adaptive functioning across exposure groups with younger children performing better than older children on three measures (language, communication, socialization). Older children performed better than younger children on a different language measure. The main effect of sex was significant for neuropsychological performance and psychopathology; across exposure groups, males had stronger language and visual-spatial scores and fewer somatic complaints than females. Conclusion Prenatal alcohol exposure resulted in impaired neuropsychological and behavioral functioning. Although adolescents with prenatal alcohol exposure may perform more poorly than younger exposed children, the same was true for non-exposed children. Thus, these cross-sectional data indicate that the developmental trajectory for neuropsychological and behavioral performance is not altered by prenatal alcohol exposure, but rather, deficits are consistent across the two age groups tested. Similarly, observed sex differences on specific measures were consistent across the groups and do not support sexually dimorphic effects in these domains. PMID:27430360

Objective To examine the dose-related effect of extracorporeal shock wave therapy (ESWT) for plantar fasciitis. Methods Sixty patients with plantar fasciitis despite conservative treatment were enrolled. The patients were divided into a low-energy group (group L: n=30, 1,000 shocks/session, energy flux density [EFD] per shock 0.08 mJ/mm2) and a medium-energy group (group M: n=30, 1,000 shocks/session, EFD 0.16 mJ/mm2). The main outcome measures were visual analogue scale (VAS), Roles and Maudsley (RM) score, and thickness of plantar fascia (PF). To compare the effects between each group, follow-up was carried out 1 week after 3 and 6 sessions, and 1 and 3 months after ESWT. Results Significant VAS and RM score improvement, and PF thickness reduction were observed in both groups (p<0.01). After 3 sessions of ESWT, group M showed significant improvement in the VAS and RM score than group L, whereas after 3 additional sessions applied in group L, the main outcomes were no longer significantly different in both groups (p>0.05). Conclusion Therapeutic effect might disclose a dose-related relationship; therefore, EFD and the times of the session are considerable factors when treating with ESWT. PMID:23869336

INTRODUCTION The aim of this study was to investigate the effect of Saccharomyces boulardii treatment on preventing bacterial translocation in an obstructive jaundice animal model. MATERIALS AND METHODS Sixty adult rats were divided into five groups: group 1 – the sham-operated group; group 2 – the common bile duct ligation group; group 3 – the S. boulardii group; group 4 – the ampicillin-sulbaktam group; and group 5 – the S. boulardii plus ampicillin-sulbaktam group. The saline, antibiotics and S. boulardii were given, respectively, for a 7-day period as a single dose per day via temporary orogastric intubation. Seven days following the obstructive jaundice, the animal had laparatomy under sterile conditions. Segments of ileum were removed for histopathological examination. Blood, liver, spleen and mesenteric lymph nodes were taken for microbiological culture. RESULTS Bacterial translocation rates were 0% in the sham-operated group, 83% in group 2, 42% in group 3, 42% in group 4 and 33% in group 5. Bacterial translocation significantly increased in group 2 compared to groups 3, 4 and 5 (P = 0.001). The bacterial counts (CFU/g) of group 2 were significantly higher than those of groups 3, 4 and 5 (P = 0.001). Histopathological examination of ileum specimens revealed a significant decrease in the heights of villi in groups 2–5 compared to the sham-operated group (P = 0.001). The mean villus height in groups 3 and 5 was significantly higher than that of group 4 (P = 0.001). CONCLUSIONS S. boulardii was found to be effective in the successful control of translocation and improvement of intestinal barrier function. PMID:16551414

[Purpose] The purpose of this study was to investigate the effects of two different stretching techniques on range of motion (ROM), muscle activation, and balance. [Subjects] For the present study, 48 adults with hamstring muscle tightness were recruited and randomly divided into three groups: a static stretching group (n=16), a PNF stretching group (n=16), a control group (n=16). [Methods] Both of the stretching techniques were applied to the hamstring once. Active knee extension angle, muscle activation during maximum voluntary isometric contraction (MVC), and static balance were measured before and after the application of each stretching technique. [Results] Both the static stretching and the PNF stretching groups showed significant increases in knee extension angle compared to the control group. However, there were no significant differences in muscle activation or balance between the groups. [Conclusion] Static stretching and PNF stretching techniques improved ROM without decrease in muscle activation, but neither of them exerted statistically significant effects on balance.

The study aims to explore the effect of positive psychological intervention (fun activities combined with positive mental health education) on the well-being, 2-week illness prevalence, and salivary immunoglobulin A of empty nesters. Ninety-two empty nesters were divided into intervention ( n = 49) and control ( n = 43) groups. The empty nesters in the intervention group performed the intervention in addition to routine community activities. The intervention group scored significantly higher on well-being ( p< .05) compared with the control group after intervention. A week after intervention, salivary immunoglobulin A of the intervention group ( p< .05) was higher than that before intervention. Meanwhile, the difference in salivary immunoglobulin A in the control group before and after intervention was not statistically significant. 2-week illness prevalence in both groups did not exhibit a significant difference ( p> .05). Results indicate that positive psychological intervention can effectively increase the well-being and salivary immunoglobulin A of empty nesters and improve their physical and mental health.

The aim of the following study is to evaluate the effect of life-style modification on postmenopausal (PM) overweight and obese Indian women in a randomized controlled 24 week study. Two groups were formed Group I (n = 30) was designated as intervention (dietary and exercise group) and Group II (n = 24) served as control. Comparison of weight, waist circumference (WC) and body mass index (BMI) were made and compared among two groups at 4, 8, 16 and 24 weeks. Mean age at menopause was 48.35 years versus 49.65 years; mean number of menopausal symptoms were 5.70 ± 1.76 versus 5.10 ± 1.56 and mean duration since menopause was 2.70 versus 2.90 years in Groups I and II respectively. When the effect of Group I and control on weight was compared at 4, 8, 16 and 24 weeks, there was no significant difference between them up to 8 week. At 8 weeks Group I caused a significant decrease in weight (P ≤ 0.05) when compared with control arm and which continued throughout the study period (P < 0.05) at both 16 and 24 weeks. Group I produced a significant reduction in WC from 8 weeks onwards up to 24 weeks (P ≤ 0.05). BMI was statistically significant in Group I and the effect started at 4(th) week (P ≤ 0.05) and the differences in BMI reduction were highly significant at 16(th) and 24(th) weeks (P ≤ 0.001). The results of the present study strongly recommend the life-style management to be incorporated in daily style of postmenopausal women under controlled supervision.

Recently, miniscrews have been used to provide anchorage during orthodontic treatment, especially for incisor intrusion. Miniscrews during incisor intrusion are commonly used in implant orthodontics. Traditionally, effective incisor intrusion has been accomplished with J-hook headgear. In this study, we compared the effect of incisor intrusion, force vector, and amount of root resorption between implant orthodontics and J-hook headgear. Lateral cephalometric radiographs from 8 patients in the implant group and 10 patients in the J-hook headgear group were analyzed for incisor retraction. The estimated force vector was analyzed in the horizontal and vertical directions in both groups. Root resorption was also measured on periapical radiographs. In the implant group, significant reductions in overjet, overbite, maxillary incisor to palatal plane, and maxillary incisor to upper lip were observed after intrusion of the incisors. In the J-hook headgear group, significant reductions in overjet, overbite, maxillary incisor to upper lip, and maxillary incisor to SN plane were observed after intrusion of the incisors. There were significantly greater reductions in overbite, maxillary incisor to palatal plane, and maxillary incisor to upper lip in the implant group than in the J-hook headgear group. Estimated force analysis resulted in significantly more force in the vertical direction and less in the horizontal direction in the implant group. Furthermore, significantly less root resorption was observed in the implant group compared with the J-hook headgear group. The maxillary incisors were effectively intruded by using miniscrews as orthodontic anchorage without patient cooperation. The amount of root resorption was not affected by activating the ligature wire from the miniscrew during incisor intrusion.

To evaluate the effect of burn rehabilitation massage therapy on hypertrophic scar after burn. One hundred and forty-six burn patients with hypertrophic scar(s) were randomly divided into an experimental group and a control group. All patients received standard rehabilitation therapy for hypertrophic scars and 76 patients (massage group) additionally received burn scar rehabilitation massage therapy. Both before and after the treatment, we determined the scores of visual analog scale (VAS) and itching scale and assessed the scar characteristics of thickness, melanin, erythema, transepidermal water loss (TEWL), sebum, and elasticity by using ultrasonography, Mexameter(®), Tewameter(®), Sebumeter(®), and Cutometer(®), respectively. The scores of both VAS and itching scale decreased significantly in both groups, indicating a significant intragroup difference. With regard to the scar characteristics, the massage group showed a significant decrease after treatment in scar thickness, melanin, erythema, TEWL and a significant intergroup difference. In terms of scar elasticity, a significant intergroup difference was noted in immediate distension and gross skin elasticity, while the massage group significant improvement in skin distensibility, immediate distension, immediate retraction, and delayed distension. Our results suggest that burn rehabilitation massage therapy is effective in improving pain, pruritus, and scar characteristics in hypertrophic scars after burn.

Obesity prevalence among Chilean children is 19.4%. The present study aimed to assess the effectiveness of a school-based obesity prevention programme. Non-randomized controlled study. The intervention included activities in nutrition and physical activity, fully applied the first year and partially in the second one. Primary outcomes were BMI Z-score (BMIZ) and obesity prevalence; secondary outcomes were waist circumference and triceps skinfold thickness. Time effects were assessed by changes in BMI-related variables by gender and period (ANOVA and Tukey test), while intervention effects were determined by comparing changes in (i) obesity prevalence by gender and period (PROC GENMOD) and (ii) BMIZ according gender, age and period (PROC MIXED). Primary schools in the Chilean cities of Casablanca (intervention group) and Quillota (control group). One thousand seven hundred and fifty-nine children from three schools (intervention group) and 671 from one school (control group). Over the two years, obesity prevalence and BMIZ declined significantly in the intervention group; from 17.0% to 12.3% and 14.1% to 10.3% in boys and girls, respectively, and from 0.62 to 0.53 and 0.64 to 0.58, respectively. In the control group, obesity remained stable at about 21% and 15%, while BMIZ increased significantly in the second year. BMIZ declined in both genders and all age categories in the intervention group during the first year (significant only in younger boys). No changes occurred during the summer, while during the second year, BMIZ increased in boys and girls from both groups (significant only in the younger control boys). Obesity declined significantly only in boys during the first year. Effectiveness was greater in the first school year and more evident in younger boys.

Power training has been shown to be more effective than conventional resistance training for improving physical function in older adults; however, most trials have used pneumatic machines during training. Considering that the general public typically has access to plate-loaded machines, the effectiveness and safety of power training using plate-loaded machines compared to pneumatic machines is an important consideration. The purpose of this investigation was to compare the effects of high-velocity training using pneumatic machines (Pn) versus standard plate-loaded machines (PL). Independently-living older adults, 60years or older were randomized into two groups: pneumatic machine (Pn, n=19) and plate-loaded machine (PL, n=17). After 12weeks of high-velocity training twice per week, groups were analyzed using an intention-to-treat approach. Primary outcomes were lower body power measured using a linear transducer and upper body power using medicine ball throw. Secondary outcomes included lower and upper body muscle muscle strength, the Physical Performance Battery (PPB), gallon jug test, the timed up-and-go test, and self-reported function using the Patient Reported Outcomes Measurement Information System (PROMIS) and an online video questionnaire. Outcome assessors were blinded to group membership. Lower body power significantly improved in both groups (Pn: 19%, PL: 31%), with no significant difference between the groups (Cohen's d=0.4, 95% CI (-1.1, 0.3)). Upper body power significantly improved only in the PL group, but showed no significant difference between the groups (Pn: 3%, PL: 6%). For balance, there was a significant difference between the groups favoring the Pn group (d=0.7, 95% CI (0.1, 1.4)); however, there were no statistically significant differences between groups for PPB, gallon jug transfer, muscle muscle strength, timed up-and-go or self-reported function. No serious adverse events were reported in either of the groups. Pneumatic and plate-loaded machines were effective in improving lower body power and physical function in older adults. The results suggest that power training can be safely and effectively performed by older adults using either pneumatic or plate-loaded machines. Copyright © 2017 Elsevier Inc. All rights reserved.

The purpose of the present study was to evaluate the efficacy of midazolam-ondansetron combination in prevention of postoperative nausea and vomiting (PONV) after middle ear surgery and its comparison with using midazolam or ondansetron alone. One hundred and forty patients were enrolled in four groups to receive midazolam 0.75 mg/kg in group M, ondansetron 4 mg in group O, midazolam 0.75 mg/kg and ondansetron 4 mg in group MO, and saline 0.90% in group S intravenously just before anesthesia. Assessment of nausea, vomiting, rescue antiemetic, and side effects of study drugs such as headache and dizziness was carried out postoperatively for 24 h. The incidence of PONV was significantly smaller in group MO than group M and group O, while there was no significant difference between group M and group O during the first 24 h postoperatively. Requirement to the additional antiemetic was significantly more in group S (71.4%) compared to other groups, while in group MO (11.4%) was lower than group M (31.4%) and group O (34.3%). Our study showed that prophylactic administration of midazolam 0.75 mg/kg combined with ondansetron 4 mg was more effective than using midazolam or ondansetron alone in prevention of PONV after middle ear surgery.

Several studies have reported the uncertain role of multi-minerals and vitamins in the prevention of preeclampsia. The present study aims to investigate the effect of multimineral-vitamin D supplements (calcium, magnesium, zinc and Vitamin D) and vitamins (C+ E) in the prevention of preeclampsia. In this randomized clinical trial, 90 pregnant women were divided into three groups: group A received Ferrous sulfate (1 tablet/day) + one tablet of Claci-care multimineral-vitamin D containing 800mg calcium, 200mg magnesium, 8mg zinc and 400 IU Vitamin D3 per day; group B received Ferrous sulfate (1 tablet/day) + 250 mg vitamin C + 55 mg vitamin E; and the controls received only one Ferrous sulfate tablet daily. The incidence of preeclampsia in group A was significantly lower than the control group (p=0.03), while there was no significant difference between group B and controls (p=0.50), as well as groups A and B (p=0.063). The incidence of neonatal complications in the group A was significantly lower than the control group (p=0.01), while there was no significant difference between group B and control (p=0.48). According to the results, calcium, magnesium, and zinc supplements have a significant effect on the prevention of preeclampsia. In addition, prescription of multimineral-vitamin D during pregnancy can be a low-cost and affordable way to reduce the incidence of preeclampsia in women who are at high risk of preeclampsia.

From 2009 to 2010, an experiment was conducted to increase response rates among African American mothers in the Wisconsin Pregnancy Risk Assessment Monitoring System (PRAMS). Sample members were randomly assigned to groups that received a prepaid, cash incentive of $5 (n = 219); a coupon for diapers valued at $6 (n = 210); or no incentive (n = 209). Incentives were included with the questionnaire, which was mailed to respondents. We examined the effects of the incentives on several outcomes, including response rates, cost effectiveness, survey response distributions, and item nonresponse. Response rates were significantly higher for the cash group than for the coupon (42.5 vs. 32.4%, P < .05) or no incentive group (42.5 vs. 30.1%, P < .01); the coupon and no incentive groups performed similarly. While absolute costs were the highest for the cash group, the cost per completed survey was the lowest. The incentives had limited effects on response distributions for specific survey questions. Although respondents completing the survey by mail in the cash and coupon groups exhibited a trend toward being less likely to have missing data, the effect was not significant. Compared to a coupon or no incentive, a small cash incentive significantly improved response rates and was cost effective among African American respondents in Wisconsin PRAMS. Incentives had only limited effects, however, on survey response distributions, and no significant effects on item nonresponse.

This study compared the effectiveness of three instructional intervention strategies for teaching nursing students about congenital heart disease (CHD). They are: (1) computer-assisted instruction (CAI), (2) traditional class room lecture (TCL); and (3) the combination of CAI and TCL. The subjects were associate degree nursing (ADN) students enrolled in a pediatric nursing course at the University of Cincinnati Raymond Walters College. Differences between pre- and post-scores on a 20-item multiple choice test were analyzed by analysis of variance. There was a significant improvement in scores for all groups but no significant difference in improvement in scores between the CAI group and the TCL group. The CAI/TCL group showed significant improvement in scores compared with the other two groups. The researcher concluded that when teaching strategies are comparable, CAI is as effective as TCL. Used together, a significant improvement is seen in student performance than when either strategy is used alone.

Objective Examine the effect of weekday exposure over six months to different lunch sizes on energy intake and body weight in a free-living sample of working adults. Design and Methods Adults (n=233) were randomly assigned to one of three lunch size groups (400 kcal; 800 kcal; 1600 kcal) or to a no-free lunch control group for six months. Weight and energy intake were measured at baseline, and months 1, 3, and 6. Results Lunch energy was significantly higher in the 800 and 1600 kcal groups compared to the 400 kcal group (p < 0.0001). Total energy was significantly higher for the 1600 kcal group compared to the 400 and 800 kcal groups (p = 0.02). Body weight change at six months did not significantly differ at the 5% level by experimental group (1600 kcal group: +1.1 kg (sd=0.44); 800 kcal group: −0.1 kg (sd=0.42); 400 kcal group: −0.1 kg (sd=0.43); control group: 1.1 (sd=0.42); p=.07). Weight gain over time was significant in the 1600 kcal box lunch group (p < 0.05). Conclusions Weekday exposure for six months to a 1600 kcal lunch caused significant increases in total energy intake and weight gain. PMID:24510841

Purpose To compare the effectiveness of an educational board game with interactive didactic instruction for teaching optometry students elements of the core optometric curriculum. Methods Forty-two optometry students were divided into two GPA-matched groups and assigned to either 12 hours of game play (game group) or 12 hours of interactive didactic instruction (lecture group). The same material from the core optometric curriculum was delivered to both groups. Game play was accomplished via an original board game. Written examinations assessed change in knowledge level. A post-intervention opinion survey assessed student attitudes. Results There was no significant difference in pre- or post-intervention test scores between the lecture and game groups (Pre-test: p = 0.9; Post-test: p = 0.5). Post-intervention test scores increased significantly from baseline (Game group: 29.3% gain, Didactic group: 31.5% gain; p<0.001 for each). The score increase difference between groups was not statistically significant (p = 0.6). The post-intervention attitude survey did not reveal any significant between group differences (p = 0.5). Conclusions Our results indicate that an educational game and interactive didactic instruction can be equally effective in teaching optometry students basic and applied science. Furthermore, both modes of instruction have the potential to be equally engaging and enjoyable experiences. PMID:27233041

To observe and compare the effects of grain-bean package, dietary fiber (DF) extracted from grain-bean package, and DF from grain corn on the blood lipids and fatty acid synthase (FAS) activity in high-fat, high-cholesterol feeding induced dyslipidemia rats, and observe its effects on regulation of sterol regulatory element protein-1c (SREBP-1c) mRNA expression in rat liver. Consolidation 50 SD rats of clean grade feeding adaptation for one week, randomly assigned into normal control group, hyperlipidemia model group, grain-bean package group, grain-bean package DF group and grain corn group. Feed with corresponding diets for 8 weeks, and measure the total cholesterol (TC), triglyceridaemia (TG), high density lipoprotein cholesterol (HDL-C), fasting blood glucose (FBG), FAS, SREBP-1c mRNA of all groups. Compared with control group, TC, TG, FBG levels of hyperlipidemia model group were significantly increased (P < 0.05). Compared with model group, TC, TG, FBG levels of grain-bean package group, grain-bean package DF group were significantly decreased, HDL-C levels significantly increased, and activity of FAS, regulation of SREBP-1c were significantly decreased (P < 0.05). The Grain-bean package dietary fiber can improve blood lipids levels of dyslipidemia rats, and decrease FAS activity and SREBP-1c mRNA expression.

Aim To assess the effect of peritonsillar infiltration of ketamine and tramadol on post tonsillectomy pain and compare the side effects. Methods The double-blind randomized clinical trial was performed on 126 patients aged 5-12 years who had been scheduled for elective tonsillectomy. The patients were randomly divided into 3 groups to receive either ketamine, tramadol, or placebo. They had American Society of Anesthesiologists physical status class I and II. All patients underwent the same method of anesthesia and surgical procedure. The three groups did not differ according to their age, sex, and duration of anesthesia and surgery. Post operative pain was evaluated using CHEOPS score. Other parameters such as the time to the first request for analgesic, hemodynamic elements, sedation score, nausea, vomiting, and hallucination were also assessed during 12 hours after surgery. Results Tramadol group had significantly lower pain scores (P = 0.005), significantly longer time to the first request for analgesic (P = 0.001), significantly shorter time to the beginning of liquid regimen (P = 0.001), and lower hemodynamic parameters such as blood pressure (P = 0.001) and heart rate (P = 0.001) than other two groups. Ketamine group had significantly greater presence of hallucinations and negative behavior than tramadol and placebo groups. The groups did not differ significantly in the presence of nausea and vomiting. Conclusion Preoperative peritonsillar infiltration of tramadol can decrease post-tonsillectomy pain, analgesic consumption, and the time to recovery without significant side effects.

To determine the effects of exercise on biomechanical properties of the superficial digital flexor tendon (SDFT) in foals. 43 Dutch Warmblood foals. From 1 week until 5 months of age, 14 foals were housed in stalls and not exercised, 14 foals were housed in stalls and exercised daily, and 15 foals were maintained at pasture. Eight foals in each group were euthanatized at 5 months, and remaining foals were housed together in a stall and paddock until euthanatized at 11 months. After euthanasia, SDFT were isolated and fit in a material testing system. Mean cross-sectional area (CSA) was measured and traction forces recorded. Normalized force at rupture (force(rup)), normalized force at 4% strain, strain at rupture, stress at 4% strain (stress(4%stain)), and stress at rupture were compared among and within groups. At 5 months, mean CSA and normalized force(rup) were significantly greater and stress(4%strain) significantly less in the pastured group, compared with the other groups. At 11 months, CSA and normalized force(rup) were not significantly different among groups, because force(rup) increased significantly from 5 to 11 months in the nonexercised group and decreased significantly in the pastured group. Exercise significantly affected the biomechanical properties of the SDFT in foals. Evenly distributed moderate- and low-intensity exercise at a young age may be more effective for development of strong, flexible tendons in horses than single episodes of high-intensity exercise superimposed on stall rest. This effect may impact later susceptibility to SDFT injury.

The effects of 14 days of increased gravitational load, and the absence of adrenal stress hormones on total body bone mineral content (BMC) were examined in male Sprague-Dawley rats. Centrifugation at 2 Gs (2G) was used to increase the gravitational load, and bilateral adrenalectomy (ADX) was used to eliminate the production of adrenal stress hormones. Stationary groups at 1 G (1G) and sham operated (SHAM) animals served as controls. Thirty rats (n=6 or 8) made up the four experimental groups (1G SHAM, 1G ADX, 2G SHAM and 2G ADX). BMC was assessed by dual energy X-ray absorptiometry (DXA) and activity was determined through biotelemetry. Body mass and food intake were also measured. Multi-factorial analysis of variance (MANCOVA) and Newman Keuls post hoc tests were used to analyze significant effects (p less than 0.05) for the primary variables. Results indicated that BMC decreased significantly with increased G for both the SHAM and ADX groups. The BMC for the 1 G ADX group was also significantly lower than the 1G SHAM group, however the 2G SHAM and ADX groups were not significantly different. There was a significant decrease in body mass with increased G and there was no ADX effect on body mass. When BMC was normalized for body mass changes, there were no significant group differences. Activity level decreased with body mass, and food intake data showed there was significant hypophagia during the first few days of centrifugation. These results suggest that the decrease in total body BMC seen with hypergravity may be based to a large extent on the differences in body mass induced by the 2 G load.

The aim of this study was to investigate the therapeutic effect of different doses of tripterygium glycosides (TG) in the treatment of diabetic nephropathy (DN). The effect of TG on blood lipids and safety were also evaluated. Sixty patients with type 2 DN were randomly divided into three groups (n=20 per group): low-dose (30 mg/day TG), double-dose (60 mg/day TG) and control (placebo) groups, all three times daily for 6 months. The levels of triglycerides, total cholesterol, urinary protein, plasma albumin and serum tumour necrosis factor (TNF)-α were compared between the three groups. After treatment, urinary protein and TNF-α level significantly decreased in patients in the treatment groups, compared with the control group. This decrease was significantly larger in the double-dose group than in the low-dose group. However, there was no significant decrease in triglycerides and total cholesterol in the two treatment groups. Furthermore, plasma albumin was lower in the treatment groups than in the control group. The double dose of TG has improved clinical efficacy, compared with the low dose, and the same safety profile. © 2018 The Author(s). Published by S. Karger AG, Basel.

1. Antioxidant and methyl donor effects of betaine in experimental animal models have recently been demonstrated. The present study was therefore designed to examine the antioxidant effects of betaine on the antioxidant status and meat quality of breast muscles in broilers. 2. Cobb broilers were randomly divided into Control, Methionine low, Methionine low plus betaine, and Betaine groups. 3. The activity of the main antioxidant enzyme (glutathione peroxidase) in the Betaine and the Methionine low plus betaine groups significantly increased compared to the Methionine low and Control groups. Catalase and superoxide dismutase activities were significantly higher in the Betaine group compared to the Methionine low group, and lipid peroxidation was significantly higher in the Control and the Methionine low groups. 4. The present study indicates that adding betaine (1 g/kg) to a diet deficient in methionine can significantly improve antioxidant defences and meat quality, decreasing lipid peroxidation in the breast muscles of broiler chickens.

The aim of this study was to investigate the effects of overtraining on skeletal muscle growth and growth-related gene expression. The rats of overtraining group (OT) and overtraining recovery group (OTR) were subject to 11 experimental weeks of overtraining protocol. It was found that the absolute gastrocnemius muscle wet weight of the OT group was significantly lower than that of the sedentary group (23.6%, P<0.01). Serum creatine kinase was significantly higher in the OT and OTR groups than the sedentary group. CD68, CD163, MyoD, myogenin, IL-1β, TNF-α, IGF-I and MGF mRNA did not change in the OT group as compared with the sedentary group. IL-6 and TGF-β1 mRNA in the OT group increased significantly as compared with the sedentary group (2.17 fold and 1.78 fold, respectively; P<0.01). IL-10 mRNA decreased significantly in the OT group (63%, P<0.01) and the OTR group (77%, P<0.01) compared to the sedentary group. COX-2 mRNA decreased significantly in the OT group (60%, P<0.01) and the OTR group (69%, P<0.01) from the sedentary group. uPA mRNA in the OT group was significantly lower than that in the sedentary group (32%, P<0.01). These data suggest that inflammatory cytokines, COX-2 and uPA may play roles in the inhibition of skeletal muscle growth induced by overtraining. © Georg Thieme Verlag KG Stuttgart · New York.

The aim of this study was to investigate the efficacy of aquatic exercises in fibromyalgia syndrome (FMS). A total of 63 patients were included and allocated to two groups. Group I (n = 33) received an aquatic exercise program and Group II (n = 30) received a home-based exercise program for 60 min, 3x a week, over 5 weeks. Patients were evaluated for pain (visual analogue scale, VAS), number of tender points (NTP), Beck depression inventory (BDI), and functional capacity (fibromyalgia impact questionnaire, FIQ). All assessment parameters were measured at baseline, and at weeks 4, 12, and 24. There were statistically significant differences in FIQ and NTP in both groups at the end and during follow-up (P < 0.05). Group I showed a statistically significant decrease in BDI scores after 4 and 12 weeks (P < 0.05) that remained after 24 weeks (P < 0.001). In Group II, a significant decrease in BDI scores was observed at the end and during follow-up (P < 0.001). Also, a significant improvement was found in VAS at weeks 4 and 12 in both groups (P < 0.001). The average of reduction in pain scores was 40% in Group1 and 21% in Group II. However, this was still significant at week 24 only in the aquatic therapy group. A comparison of the two groups showed no statistically significant difference for FIQ, NTP, and BDI scores except VAS (P < 0.001) Our results showed that both aquatic therapy and home-based exercise programs have beneficial effects on FIQ, BDI, and NTP. In pain management, only aquatic therapy seems to have long-term effects.

The present study was designed to compare the effects of nano-selenium and of sodium selenite on the chemotactic and respiratory burst activities of neutrophils in sheep. Fifteen sheep were randomly divided into three groups. Groups 1 and 2 received selenium nanoparticles (1 mg/kg) or sodium selenite (1 mg/kg) orally, respectively, for ten consecutive days, and the third group was considered as the control. To determine the chemotactic and respiratory burst activities of the neutrophils, the leading front assay and the NBT test were used on heparinized blood samples that were collected at different intervals (days 0, 10th, 20th, and 30th). The results obtained showed that the chemotactic activities in groups 1 and 2 increased significantly on the 10th, 20th, and 30th day, compared to day 0, and on the 20th day in comparison with the 10th day, while in group 2, there was a significant decrease on the 30th day compared to the 20th day. The chemotactic activities in group 1 were significantly higher than in group 2 on the 10th day and in the control group on the 10th, 20th, and 30th day, but the chemotactic activities in group 2 were significantly higher than those in the control group only on the 20th day. On the 30th day into the experiment, the respiratory bursts in groups 1 and 2 were significantly stronger in comparison with those at day 0. Overall, nano-selenium increased the chemotactic and respiratory burst activities more significantly than sodium selenite, which is suggestive of a stronger stimulatory effect of the Se nanoparticles on intracellular activities.

Objective: To investigate the effect of dietary control combined with different exercise modes on plasma vaspin, irisin, and metabolic parameters in patients with non-alcoholic fatty liver disease (NAFLD) through a randomized open parallel-controlled study. Methods: The patients aged 30-65 years who visited Tianjin Third Central Hospital from January 2013 to December 2014 and were diagnosed with NAFLD by liver ultrasound and fat content determination were screening, and 474 patients were enrolled in this randomized controlled trial and divided into aerobic exercise group, resistance exercise group, and control group. All patients received dietary intervention. The three groups were compared in terms of biochemical parameters, fat content, NFS score, energy metabolic parameters, body composition index, and levels of vaspin and irisin at baseline and after 6 months of intervention. SPSS 19.0 was used for statistical analysis. The t -test, the Mann-Whitney U test, the chi-square test, and an analysis of variance were used for comparison between groups. The multiple imputation method was used for missing data, and the results were included in the intention-to-treat analysis. Results: There were no significant differences in age, sex, anthropometrical parameters, and biochemical parameters between the three groups at baseline. Compared with dietary control alone, aerobic exercise and resistance exercise helped to achieve significant reductions in waist circumference, diastolic pressure, percentage of body fat, volatile fatty acid, fasting blood glucose, homeostasis model assessment of insulin resistance, triglyceride, low-density lipoprotein cholesterol, free fatty acid, uric acid, alanine aminotransferase, and liver fat content after 6 months of intervention ( P < 0.05). The aerobic exercise group had a significant increase in non-protein respiratory quotient and significant reductions in body mass index and aspartate aminotransferase after intervention, as well as a significant increase in resting energy expenditure and significant reductions in abdominal fat ratio and total cholesterol after 6 months of resistance exercise ( P < 0.05). The aerobic exercise group and the resistance exercise group had a significant reduction in vaspin and a significant increase in irisin after intervention ( P < 0.05), and the resistance exercise group had significantly greater changes in these two adipokines than the aerobic exercise group ( P < 0.05). Conclusion: Exercise therapy is an effective method for the treatment of metabolism-associated diseases, and a combination of resistance and aerobic exercises is more reasonable and effective in clinical practice. As a relatively safe exercise mode, resistance exercise can also effectively improve the metabolic state of NAFLD patients.

To observe the clinical effect of ear point embedding on plasma and effect site concentrations of propofol-remifentanil in elderly patients who underwent abdominal external hernia surgery at the time of consciousness and pain disappearing by target-controlled infusion (TCI) and bispectral index (BIS). Fifty patients who underwent elective abdominal hernia surgery were randomly assigned into an observation group and a control group, 25 cases in each one. In the observation group, 30 minutes before anesthesia induction, Fugugou (Extra), Gan (CO 12 ), Pizhixia (AT 4 ), and Shenmen (TF 4 ) were embedded by auricular needles until the end of surgery, 10 times of counter press each point. In the control group, the same amount of auricular tape was applied until the end of surgery at the same points without stimulation 30 minutes before anesthesia induction. Patients in the two groups were given total intravenous anesthesia, and BIS was monitored by BIS anesthesia depth monitor. Propofol was infused by TCI at a beginning concentration of 1.5μg/L and increased by 0.3μg/L every 30s until the patients lost their consciousness. After that, remifentanil was infused by TCI at a beginning concentration of 2.0μg/L and increased by 0.3μg/L every 30s until the patients had no body reaction to pain stimulation (orbital reflex). Indices were recorded, including mean arterial pressure (MAP), heart rate (HR) and the BIS values, at the time of T 0 (entering into the operation room), T 1 (losing consciousness) and T 2 (pain relief), the plasma and effect site concentrations of propofol at T 1 , the plasma and effect site concentrations of remifentanil at T 2 . After surgery we recorded the total amounts of propofol and remifentanil, surgery time and anesthesia time. At T 1 and T 2 , MAP and HR of the observation group were higher than those of the control group ( P <0.05, P <0.01). At T 1 , the plasma and effect site concentrations of propofol in the observation group were significantly lower than those in the control group ( P <0.05, P <0.01). At T 2 , the plasma and effect site concentrations of remifentanil in the observation group were significantly lower than those in the control group ( P <0.05, P <0.01). There was no significant difference in BIS values at T 1 and T 2 between the two groups (both P >0.05). There was no significant difference in operation time and anesthesia time between the two groups (both P >0.05). The total amount of remifentanil in the observation group was significantly lower than that in the control group ( P <0.01). There was no significant difference in the total amount of propofol between the two groups ( P >0.05). Ear points embedding combined with propofol-remifentanil TCI could reduce the plasma and effect site concentrations of propofol and remifentanil and the total amount of remifentanil in elderly patients with extra-abdominal hernia surgery, and had the effect of assisting sedation and analgesia.

Depression and anxiety disorders are two of the most common mental disorders in the United States. These disorders are prevalent among college students. The main objective of this study is to compare the effectiveness of two different types of intervention practices (mindfulness vs. yoga) and a noninterventional control group in mitigating the effects of depression and/or anxiety in college students. A sample of 90 students (both genders) over age 18 who had a diagnosis of anxiety and/or depression was recruited from 11,500 undergraduate college students in a mid-size university. The study's design included stratified-randomized controlled repeated measures with three groups: a mindfulness intervention group, a yoga-only intervention group, and a noninterventional group. Participants were randomly assigned to the aforementioned three groups. Participants in the intervention groups received an 8-week training either in mindfulness or yoga. Depressive, anxiety, stress symptoms, self-compassion, and mindfulness were measured at baseline, Week 4, Week 8, and Week 12. Depressive, anxiety, and stress symptoms decreased significantly (p < .01) from baseline to follow-up conditions in both the mindfulness and yoga intervention groups. The changes in mindfulness scores were also significant in both groups. However, the changes in self-compassion scores were significant only in the mindfulness intervention group. No significant changes in the control group were demonstrated. The findings from this study can provide useful information to nurses and other health care providers. This study may have implications for a cost-effective treatment for depression and anxiety. © The Author(s) 2016.

To evaluate the effect of drainage tube on prognosis after total knee arthroplasty (TKA) and explore an effective treatment with favorable prognosis. In a prospective study, 18 patients with TKA for the first time were included and randomly divided into three groups, group A (no placement of drainage tube), group B (negative pressure drainage), and group C (4 h clamping drainage). Intraoperative and postoperative blood loss, operation time, and the drainage volume were recorded and analyzed. Arthrocele, ecchymosis, and range of motion (ROM) were examined postoperatively. The degree of pain was scored by Visual Analog Scale (VAS) after 6, 12, and 24 h of operation. The complications were examined and HSS (hospital for special surgery) knee score was taken during the follow-up period. There was no significant difference in operation time, total blood loss, intraoperative blood loss, and VAS score among three groups. Meanwhile, the hidden blood loss in group B was significantly decreased compared with group A (P = 0.0015). The postoperative drainage volume of group B was significantly increased compared with group C (P = 0.0002). No drainage increased the rate of arthrocele and ecchymosis. Compared with group A, ROM after 3 days of operation in groups B and C was significantly increased (P = 0.0357, P = 0.0372, respectively). During follow-up study, no deep infection or deep venous thrombosis was found. After TKA, early clamping of the drainage tube reduced the bleeding loss without adverse effect on prognosis, which might be useful for clinical application in future.

To investigate if Erigeron Breviscapus (vant) Hand-Mazz (EBHM) has a neuroprotective effect against NMDA-induced neuron death in retinal ganglion cell layer (RGCL). Sixty healthy SD rats were randomly divided into four groups. 6 animals were in normal control group (group A). The others were divided as group B (EBHM group), group C (normal saline+NMDA group), group D (EBHM+NMDA group). Each group has 18 rats. 10 nmol NMDA was chosen for intravitreal injection to cause partial damage of the neurons in RGCL in the right eyes of Groups C and D. Same volume PBS was intravitreal injected in the left eyes as self-control. Groups B and D were pre-treated intraperitoneally with 6% EBHM solution at a dose of 15 mg x 100 g(-1) x d(-1) seven days before and after NMDA treatment. Group C were administrated intraperitoneally with 0.9% normal saline at the same time of EBHM injection. Rats were sacrificed in 4, 7, 14 days after NMDA treatment. Flat preparation of whole retinas were stained with 0.5% cresyl violet and neuron counting in RGCL from both eyes. Each subgroup has 6 rats. There was no significant difference between the right eye and the left eye of neuron counting from RGCL in normal control group (group A) (P=0.200). There was no significant difference between normal control group and EBHM group either in the right eyes or in the left eye in 4 days, 7 days and 14 days respectively after intravitreal injection of 10 nmol NMDA in group C and group D. (P=0.636, P=0.193). Neuron counting from RGCL of group C and group D were significant decreased in the NMDA-treated eyes in 4 days, 7 days and 14 days after intravitreal injection (P < 0.001). There ws no significant difference between self-control eyes and normal control group (P > 0.05). Neuron counting was significantly higher in the EBHM+NMDA group than normal saline+NMDA group at 14 days after intraviteal injection (P=0.044). However,it is obvious that the difference was still significant between normal control group and EBHM+NMDA group (P < 0.05). EBHM has no effect on neuron counting of RGCL when administered alone in normal rats. It is suggested that EBHM has partial protective effect on NMDA-induced neuron loss in RGCL in the rat.

The curative effects of monosialotetrahexosyl ganglioside (GM1) in the treatment of severe ischemic brain injury and its effects on tumor necrosis factor-α (TNF-α) and neuropathy disability score (NDS). Sixty patients with severe ischemic brain injury admitted to The First People's Hospital of Jining (Jining, China) from June 2014 to March 2016 were selected. They were randomly divided into the control group (n=30) and the experimental group (n=30). The patients in the control group were treated with routine therapy while those in the experimental group were treated with GM1. The level of TNF-α in the serum was measured by the enzyme-linked immunosorbent assay. The NDS was used to grade the two groups; Pearson's correlation coefficient was applied to analyze the correlation between the content of TNF-α and NDS; the content of superoxide dismutase (SOD) was detected using xanthine oxidase assay, and the content of malondialdehyde (MDA) was detected by thiobarbituric acid method. The clinical recovery time of two groups of patients was recorded. At 14 days after GM1 treatment, the serum TNF-α content and the NDS in the experimental group were significantly lower than those in the control group (P<0.05). The content of TNF-α in the patients was positively correlated with the NDS. After treatment, the serum MDA content of patients in the experimental group was lower, while the SOD content was significantly higher than that in the control group (P<0.05). After GM1 treatment, hemodynamic parameters of patients in the experimental group were significantly improved compared with those in the control group. The total effective rate of GM1 treatment in the experimental group was higher than that in the control group (P<0.05). GM1 has a good clinical significance in the treatment of patients with severe ischemic brain injury and is worthy of clinical promotion and application.

The purpose of this study was investigating the effects of curcumin on the histological changes and functional recovery following spinal cord injury (SCI) in a rat model. Following either sham operation or SCI, 36 male Sprague-Dawley rats were distributed into three groups: sham group, curcumin-treated group, and vehicle-injected group. Locomotor function was assessed according to the Basso, Beattie, and Bresnahan (BBB) scale in rats who had received daily intraperitoneal injections of 200 mg/kg curcumin or an equivalent volume of vehicle for 7 days following SCI. The injured spinal cord was then examined histologically, including quantification of cavitation. BBB scores were significantly higher in rats receiving curcumin than receiving vehicle (P < 0.05). The cavity volume was significantly reduced in the curcumin group as compared to the control group (P = 0.039). Superoxide dismutase (SOD) activity was significantly elevated in the curcumin group as compared to the vehicle group but was not significantly different from the sham group (P < 0.05, P > 0.05, respectively) at one and two weeks after SCI. Malondialdehyde (MDA) levels were significantly elevated in the vehicle group as compared to the sham group (P < 0.05 at 1 and 2 weeks). MDA activity was significantly reduced in the curcumin group at 2 weeks after SCI when compared to the vehicle group (P = 0.004). The numbers of macrophage were significantly decreased in the curcumin group (P = 0.001). This study demonstrated that curcumin enhances early functional recovery after SCI by diminishing cavitation volume, anti-inflammatory reactions, and antioxidant activity.

The objective of this study was to explore the effects of proton pump inhibitors (PPIs) on the development and prognosis of lung cancer precise radiotherapy-induced radiation pneumonitis. Clinical materials of 84 lung cancer patients who had radiation pneumonitis after precise radiotherapy were retrospectively analyzed, and the patients were divided into PPI group and control group, according to whether or not PPIs were applied. The development and prognosis of patients and the effects of different doses of PPI on patient condition from two groups were compared. There were 57 PPI cases in PPI group and 27 cases in control group. Basic characteristics of patients were not statistically different between the two groups; however, white blood cell count, oxygenation indexes, blood gas pH, and lung imaging index were significantly different (p < 0.05), indicating that radiation pneumonitis tended to be more severe in PPI group. As regards effects of PPI on prognosis of two groups, remission rate of radiation pneumonia in PPI group was significantly less than that of the control group. Among 57 cases in PPI group, there were 31 patients applied with PPI ≤ 1DDD and 31 patients applied with PPI > 1DDD. In comparison of the various parameters of patients, 7 days after being applied with different doses of PPI, there were no significant differences between the parameters of radiation pneumonitis. PPIs should be cautiously utilized to avoid the effects of lung cancer radiotherapy-induced radiation pneumonia.

This study aimed at verifying the effects of phonophoresis associated with Arnica montana on the acute phase of an inflammatory muscle lesion. Forty Wistar male rats (300+/-50 g), of which the Tibialis Anterior muscle was surgically lesioned, were divided into four groups (n=10 each): control group received no treatment; the ultrasound group (US) was treated in pulsed mode with 1-MHz frequency, 0.5 W/cm(2) intensity (spatial and temporal average - SATA), duty cycle of 1:2 (2 ms on, 4 ms off, 50%), time of application 3 min per session, one session per day, for 3 days; the phonophoresis or ultrasound plus arnica (US+A) group was treated with arnica with the same US parameters plus arnica gel; and the arnica group (A) was submitted to massage with arnica gel, also for 3 min, once a day, for 3 days. Treatment started 24h after the surgical lesion. On the 4th day after lesion creation, animals were sacrificed and sections of the lesioned, inflamed muscle were removed for quantitative (mononuclear and polymorphonuclear cell count) and qualitative histological analysis. Collected data from the 4 groups were statistically analyzed and the significance level set at p<0.05. Results show higher mononuclear cell density in all three treated groups with no significant difference between them, but values were significantly different (p<0.0001) when compared to control group's. As to polymorphonuclear cell density, significant differences were found between control group (p=0.0134) and US, US+A and A groups; the arnica group presented lesser density of polymorphonuclear cells when compared (p=0.0134) to the other groups. No significant difference was found between US and US+A groups. While the massage with arnica gel proved to be an effective anti-inflammatory on acute muscle lesion in topic use, these results point to ineffectiveness of Arnica montana phonophoresis, US having seemingly checked or minimized its anti-inflammatory effect.

The conventional treatment group were given thorough gastric lavage with water, the sodium bicarbonate + ulinastatin group were given gastric lavage with 2% sodium bicarbonate solution. Both groups were given such treatments as catharsis, administration of oxygen, fluid infusion, diuresis, and antidotes such as atropine and pralidoxime methylchloride. On the basis of comprehensive treatment, people in the sodium bicarbonate+ulinastatin group were given 5% sodium bicarbonate injection and ulinastatin. The clinical effect of the two groups were compared. The serum cholinesterase activity of the sodium bicarbonate+ulinastatin group was significantly higher than the conventional treatment group from the 5th day, and the difference was statistically significant (P<0.05) . The total atropine dosage, total pralidoxime methylchloride dosage and hospitalization days were better than the conventional treatment group, and the differences were statistically significant (P<0.05) . The difference in the time of atropinization between the two groups was not statistically significant (P>0.05) . The results of arterial blood pH, HCO3- of the sodium bicarbonate + ulinastatin group were higher than the conventional treatment group, and the difference of HCO3- at the 10th day was statistically significant (P<0.05) . Sodium bicarbonate combined with ulinastatin can improve the therapeutic effect and reduce complications in the treatment of acute phoxim pesticide poisoning, and have beneficial effects on the recovery of cholinesterase activity.

To compare the effectiveness of the topical and subconjunctival (SC) ranibizumab treatment in experimental corneal neovascularization (NV) model in rats. A model of NV was generated by cauterizing right corneas of 30 Sprague-Dawley rats with silver nitrate. The animals were separated into five groups randomly. first group (control group) received topical artificial tear drops two times daily while second and third groups received topical ranibizumab four times daily at concentrations of 5 mg/mL and 10 mg/mL, respectively. Forth and fifth groups were given 0.5 mg/0.05 mL and 1 mg/0.1 mL of SC ranibizumab in the 1st, 3rd and 7th days. The measurements (percentage of NV area and number of vessels) from digital photographs of the corneas were determined and analyzed using analysis software (ImageJ, v1.38). The animals were sacrificed on the 10th day and their corneas were subjected to hemotoxylin-eosin histopathological staining and antisera against CD34 and von-Willebrand factor to evaluate microvascular structures immunohistochemically. The percentage of the corneal NV area and number of vessels in all treatment groups was found to be significantly lower than the control group. There was no significant difference in relation to the percentage of NV area and number of vessels in the treatment groups. Score of the corneal edema was determined to be significantly less in the groups that undertook treatment. Number of vessels and inflammatory cells were significantly lower in the histological and immunohistochemical sections in the treated groups than in the control group. In all treatment groups, fibroblast intensity was significantly lower than the control group (p = 0.005). Topical or SC administration of ranibizumab seems to be a promising and effective medication in the treatment of corneal NV. Further research is recommended to assess the potential side effects and effective dose.

The purpose of this study was to examine effects of enneagram group counseling program on self-identification and depression in nursing college students. Three groups, categorized by how the students solve their conflicts, were selected to identify changes from the program. A quasi-experimental study with a non-equivalent control group and pre posttest design was used. Participants were assigned to the experimental group (n=30) or control group (n=33). The experimental group participated in enneagram group counseling program for 38 hours through eight sessions covering four different topics. Collected data were analyzed using Chi-square test, Fisher's exact test, t-test, and Wilcoxon signed rank test. Total self-identity score for the experimental group was significantly higher than the control group. However, there was no significant difference between the two groups for depression scores. The Assertive and Compliant groups demonstrated significant change in self-identification while the Withdrawn groups did not reveal any change. Results indicate that the enneagram group counseling program is very effective in establishing positive self-identification for nursing college students who face developmental crisis and stressful situations. It is also expected that this program would be useful to enhance the students' confidence through a deeper understanding and acceptance of themselves.

To study the effect of lead and (or) selenium on learning and memory ability in rats. SPF Wistar rats, after weaning, were divided into six groups, control group, Pb group (respectively Pb exposed), Se group (respectively Se added), Pb-Se group (added Se after Pb exposure), Se-Pb group (added Se before Pb exposure) and Pb + Se group (Pb and Se exposed simultaneously). After intervention for six weeks in rats, the spatial learning and memory of each group rats were measured by Morris water maze assay. Rats in Pb group had significantly longer latency, less site crossings, less percentage of time and distance spent in the target quadrant, and bigger first bearing compared with control group (P < 0.05). Rats in Pb and Se joint exposure groups had significantly shorter latency, more site crossings, less percentage of time and distance spent in the target quadrant, and smaller first bearing compared with Pb group (P < 0.05). There were no significant differences in the indexes of spatial learning and memory ability between the groups of lead and selenium joint exposure groups (P > 0.05). Lead damaged the ability of learning and memory in rats and organic selenium had protective effects on Pb-induced spatial learning and memory deficits in rats.

Purpose We evaluated the long-term effects of loxoprofen on nocturia in patients with benign prostatic hyperplasia (BPH). Materials and Methods Between January 2006 and December 2008, 40 BPH patients with 2 or more episodes of nocturia received an alpha-blocker, 5-alpha reductase inhibitor, and a single dose of 60 mg of loxoprofen at night before sleep for 12 months (Group I). During the same period, 38 BPH patients selected as the control group received an alpha-blocker and 5-alpha reductase inhibitor (Group II). Patients were reevaluated after 3, 6, and 12 months of treatment by the number of nocturia episodes and side effects. Results After 3 months of treatment, the number of nocturia episodes decreased significantly compared with baseline in both group I and group II (1.9±0.7, 2.1±0.7, respectively, p<0.05). The degree of decrease in nocturia was significantly different between the groups (-1.5±0.9, -1.1±0.9, respectively, p=0.034). After 6 and 12 months, the number of nocturia episodes decreased significantly compared with baseline in both group I and group II (p<0.05), but the degree of decrease was not significantly different between the groups (p>0.05). After 6 and 12 months of treatment in group I, treatment-emergent adverse events, including 5 cases of gastric discomfort (12.5%), 3 cases of leg edema (7.5%), and 1 case of decreased urine volume (2.5%), occurred in 9 of the 40 (22.5%) patients. Conclusions Loxoprofen can be an effective treatment for patients with nocturia secondary to BPH in the short term. Long-term use of loxoprofen is not recommended because of the side effects.

Acute hemodynamic responses to electroconvulsive therapy (ECT) may increase the risk of cardiovascular complications in vulnerable patients. The aim of the current study was to assess the effect of small-dose dexmedetomidine on hyperdynamic responses to ECT. Seventy-eight patients were enrolled and randomly allocated to receive either 0.2 μg/kg dexmedetomidine (Dex group, n = 39) or saline (Control group, n = 39) prior to ECT. Heart rate (HR) and mean arterial pressure (MAP) were recorded immediately after the administration of dexmedetomidine (T1), and 0, 1, 3, 5 and 10 min after the electrical stimuli ended (T2, T3, T4, T5 and T6). In addition, the peak HR after ECT, seizure duration, recovery time, and incidence rates of post-ECT adverse effects (agitation, headache and nausea) were also recorded. HR and MAP in the Dex group were significantly lower than those in the Control group from T2 to T5. In addition, peak HR was significantly lower in the Dex group compared with that in the Control group. Seizure length and time to spontaneous breathing, eye opening, and obeying commands in the Dex group were similar to those in the Control group. The incidence rates of post-ECT agitation and headache in the Dex group were significantly lower than that in the Control group. The administration of 0.2 μg/kg dexmedetomidine to patients receiving ECT leads to a significant reduction in HR, MAP, and peak HR responses to ECT without altering seizure duration or delaying recovery. Furthermore, dexmedetomidine effectively reduced the incidence rates of post-ECT adverse effects such as agitation and headache. Copyright © 2017. Published by Elsevier Taiwan LLC.

To compare the effectiveness of anatomical single-bundle (ASB) and over-the-top single-bundle (OSB) reconstruction of the anterior cruciate ligament (ACL). Between January 2008 and June 2008, 64 patients with ACL injury underwent arthroscopic ACL reconstruction. ASB ACL reconstruction was performed in 28 cases (ASB group) and OSB ACL reconstruction in 36 cases (OSB group). There was no significant difference in gender, age, disease duration, International Knee Documentation Committee (IKDC) score, Lysholm score, and side-to-side difference between 2 groups (P > 0.05). All incisions healed by first intention; no infection or other complications occurred. All cases were followed up 20-24 months (mean, 21.5 months). There were significant differences in the IKDC score, Lysholm score, and the side-to-side difference between last follow-up and preoperation in 2 groups (P < 0.05), but there was no significant difference between 2 groups at last follow-up (P > 0.05). Significant differences were found in negative rate of the pivot shift test between last follow-up and preoperation in ASB group and between 2 groups at last follow-up (P < 0.05), but there was no significant difference between last follow-up and preoperation in OSB group (P > 0.05). The effectiveness of arthroscopic ASB ACL reconstruction is better than that of arthroscopic OSB ACL reconstruction, especially in controlling rotational stability.

This study aimed to investigate the effect of horse riding simulation (HRS) on balance and trunk muscle activation as well as to provide evidence of the therapeutic benefits of the exercise. Thirty elderly subjects were recruited from a medical care hospital and randomly divided into an experimental and a control group. The experimental group performed the HRS exercise for 20 min, 5 times a week, for 8 weeks, and conventional therapy was also provided as usual. The muscle activation and limits of stability (LOS) were measured. The LOS significantly increased in the HRS group (p<0.05) but not in the control group (p>0.05). The activation of all muscles significantly increased in the HRS group. However, in the control group, the muscle activations of the lateral low-back (external oblique and quadratus lumborum) and gluteus medius (GM) significantly decreased, and there was no significant difference in other muscles. After the intervention, the LOS and all muscle activations significantly increased in the HRS group compared with the control group. The results suggest that the HRS exercise is effective for reducing the overall risk of falling in the elderly. Thus, it is believed that horse riding exercise would help to increase dynamic stability and to prevent elderly people from falling. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Higher fibre intakes are associated with risk reduction for chronic diseases. This study investigated the effects of supplementation with PolyGlycopleX® (PGX), a complexed polysaccharide, on insulin, glucose and lipids in overweight and obese individuals. In this double-blind 12 months study, participants were randomised into three groups: control (rice flour); PGX or psyllium (PSY). Participants followed their usual lifestyle and diet but consumed 5 g of their supplement before meals. Insulin was significantly lower in the PGX and PSY groups compared to control at 3 and 6 months and in the PSY group compared to control at 12 months. Serum glucose was significantly lower in the PGX group at 3 months compared to control. Total cholesterol was significantly lower in the PGX and PSY groups compared to control at 3 and 6 months. High density lipoprotein (HDL) cholesterol was significantly increased in the PGX group compared to control at 12 months. low density lipoprotein (LDL) cholesterol was significantly lower in the PGX group at 3 and 6 months compared to control and in the PSY group at 3 months compared to control. A simple strategy of fibre supplementation may offer an effective solution to glucose, insulin and lipid management without the need for other nutrient modification. PMID:28146065

The aim of this study was to evaluate the effect of orlistat or metformin combined with Diane-35 on anthropometric, hormonal and metabolic parameters in overweight and obese polycystic ovary syndrome (PCOS) patients with insulin resistance (fasting insulin > 10 mIU/L). A total of 240 PCOS women were randomly allocated to orlistat plus Diane-35(OD group), metformin plus Diane-35(MD group), orlistat plus metformin plus Diane-35(OMD group) or Diane-35 (D group). Body weight, BMI, waist and hip circumference, blood pressure, endocrine profile, lipid profile and insulin resistance were assessed at baseline and after 3 months. Significant reductions in waist and hip circumference, serum LH, total testosterone and uric acid were observed in all groups compared with baseline. TG and TC significantly decreased in the OD group. Homeostasis model assessment insulin resistance (HOMA-IR) index was reduced in the OD (p = .015), MD (p = .001) and OMD (p = .004) groups. Body weight, BMI, systolic BP and HDL-C significantly changed in the OD and OMD group compared with the D group (p < .05). Side effects were less with orlistat than metformin. This study demonstrated that orlistat is more effective in reducing weight and lipid profile than metformin. Besides, orlistat has mild side-effects and is better tolerated compared with metformin.

To investigate the protective effect of compound bismuth and magnesium granules on aspirin-induced gastric mucosal injury in rats and its possible mechanism. Acute gastric mucosal injury model was developed with intraperitoneal injection of aspirin in Wistar rats. The rats were divided into normal control group, injury group, sucralfate protection group, compound bismuth and magnesium granules protection group and its herbal components protection group(each group 12 rats). In the protection groups, drugs as mentioned above were administered by gavage before treated with intraperitoneal injection of aspirin. To evaluate the extent of gastric mucosal injury and the protective effect of drugs, gastric mucosal lesion index, gastric mucosal blood flow, content of gastric mucosal hexosamine, prostaglandins (PG), nitric oxide(NO), tumor necrosis factor (TNF), and interleukin (IL) -1, 2, 8 were measured in each group, and histological changes were observed by gross as well as under microscope and electron microscope. Contents of hexosamine, NO, and PG in all the protection groups were significantly higher than those in the injury group (all P<0.01), and content of NO in the compound bismuth and magnesium granules group was significantly higher than that in the sucralfate group ((11.29±0.51) vs(10.80±0.36)nmol/ml, P<0.05). The gastric mucosal lesion index, contents of TNF, and IL-1, 2, 8 were significantly lower in all the protection groups than in the injury group (all P<0.01), and contents of IL-2 and IL-8 in the compound bismuth and magnesium granules group were significantly lower than those in the sucralfate group ((328.17±6.56) vs(340.23±8.05)pg/ml, P<0.01; (170.82±7.31) vs(179.31±7.80)pg/ml, P<0.05). Tissue injury and inflammatory reaction in all the protection groups were obviously mitigated compared with the injury group. Compound bismuth and magnesium granules and its herbal components may have significant protective effect on aspirin-induced gastric mucosal injury.

Our aim was to characterize the changes in messenger RNA (mRNA) abundance, protein, and activity levels of the enzymatic antioxidants, superoxide dismutase (SOD), glutathione peroxidase, and catalase by exercise training combined with L-arginine after myocardial infarction (MI). L-Arginine (1 g x kg(-1) x d(-1)) and N(G)-nitro-L-arginine methyl ester (L-NAME; 10 mg x kg(-1) x d(-1)) were administered in drinking water for 8 wk. Sprague-Dawley rats were randomized to the following groups: sham-operated control (Sham); MI sedentary (Sed); MI exercise (Ex); MI sedentary + L-arginine (Sed + LA); MI exercise + L-arginine (Ex + LA); MI sedentary + L-NAME (Sed + L-NAME); and MI exercise + L-NAME (Ex + L-NAME). The glutathione peroxidase, catalase, and gp91(phox) mRNA levels were comparable among all the groups. The SOD mRNA level was significantly increased in the Ex group (5.43 +/- 0.87) compared with the Sed group (1.74 +/- 0.29), whereas this effect was pronouncedly down-regulated by the L-NAME intervention (2.51 +/- 1.17, P < 0.05). The protein levels of SOD in the Sed and Ex groups were both significantly decreased with the administration of L-NAME. The protein levels of catalase were significantly higher in the Ex and Ex + LA groups than that in the Sed, Sed + LA, and L-NAME-treated groups. The collagen volume fraction was significantly lowered by the exercise and/or L-arginine treatment when compared with the Sed group. Fractional shortening was significantly preserved in the trained groups compared with their corresponding sedentary groups with or without drug treatments. However, the beneficial effect was not further improved by L-arginine treatment. Our results suggest that exercise training exerts antioxidative effects and attenuates myocardial fibrosis in the MI rats. These improvements, in turn, alleviate cardiac stiffness and preserve post-MI cardiac function. In addition, L-arginine appears to have no additive effect on cardiac function or expression of enzymatic antioxidants.

Physiotherapy using muscle strengthening and stretching exercises is claimed to have beneficial effects in the treatment of Legg-Calvé-Perthes disease; however, no scientific evidence is available concerning effectiveness of treatment. The purpose of the present study was to clinically evaluate possible effects of the proposed physiotherapeutic effects compared to observational follow-up in patients with Legg-Calvé-Perthes disease. A prospective follow-up study was conducted in 17 patients with unilateral Legg-Calvé-Perthes disease, divided into 2 groups: Group A (observational follow-up) and Group B (physiotherapeutic follow-up). In order to evaluate the outcome of the adopted treatments, the following parameters were assessed: articular range of motion, level of muscular strength, level of articular dysfunction, and radiographic status, both before and after the treatment. Group B exhibited significant improvement in articular range of motion concerning hip flexion, extension, abduction, adduction, medial rotation, and lateral rotation, while in Group A an equally significant worsening occurred concerning abduction, adduction, and medial rotation. Muscular strength also improved in Group B, mainly in the set of hip flexor muscles, while Group A showed no changes. Articular dysfunction after therapy compared to pretherapy was significantly reduced in Group B and increased in Group A. Patients undergoing physiotherapy exercises showed no changes in their radiographic features. Physiotherapy produced significant improvement in articular range of motion, muscular strength, and articular dysfunction in patients with Legg-Calvé-Perthes disease, but these improvements were not evident on radiographs.

Laparoscopy is more beneficial than the conventional open technique, however the pneumoperitoneum created may have an ischemic side effect. Our aim was to evaluate the protective effects of preconditioning during laparoscopic cholecystectomies (LC). 30 patients were randomized into 2 groups: I. PreC (preconditioning: 5 min. inflation, 5 min. deflation, followed by conventional LC), II: LC (conventional LC). Blood samples were taken before hospitalization (C = control), before surgery, after anaesthesia (B.S.), after surgery (A.S.) and 24 hours after the procedure (24 h). Measured parameters were: malondialdehyde (MDA), reduced glutathione (GSH), sulfhydril groups (-SH), superoxide-dismutase (SOD), catalase (CAT), myeloperoxidase (MPO), length of hospitalization and pain (VAS = visual analogue scale). Compared to the BS levels, no significant changes were detected in SOD's activity and MDA levels. GSH concentrations were significantly increased in the PreC group after operation. SH-, MPO, CAT and liver function enzymes were not significantly different. Hospitalization was shorter in the PreC group. Based on the VAS score patients had less pain in the PreC group. Significant differences concerning PreC group were found in GSH values. In the PreC group pain decreased by 2-2.5 units following the procedure, 24 h after surgery, and hospitalisation was also significantly shorter. In our pilot study the potential protective effect of preconditioning could be defined.

The present randomized controlled trial was conducted to evaluate acellular dermal matrix (ADM) graft in terms of patient satisfaction and its effectiveness and efficiency in the treatment of gingival recession. Fourteen patients (seven males and seven females) with Miller Class I and II recessions > or =3 mm participated in this 6-month clinical study. They were assigned randomly to the ADM group (ADM graft and coronally positioned flap [CPF]) or the CPF group (CPF alone). Results were evaluated based on parameters measuring patient satisfaction and clinical outcomes associated with the two treatment procedures. Significance was set at P <0.05. The mean recession was 4.0 +/- 1.0 mm and 3.7 +/- 0.7 mm for the ADM and CPF groups, respectively. For the ADM group, the defect coverage was 3.85 +/- 0.89 mm or 97.14% compared to the CPF group, in which the defect coverage was 2.85 +/- 0.89 mm or 77.42%. The difference between the two groups was statistically significant (P <0.05). There were no statistically significant differences between the two groups in the remaining clinical parameters and overall patient satisfaction except in criteria related to patient comfort and cost effectiveness, in which CPF alone produced significantly better results (P <0.03). ADM graft is significantly superior with regard to effectiveness and efficiency in the treatment of gingival recession than CPF alone. CPF emerges as a better option than ADM graft in terms of cost effectiveness and patient comfort.

To evaluate the effects of thyroid cystectomy for primary hyperparathyroidism on immune function. Ninety-two patients with parathyroid cysts complicated with primary hyperparathyroidism were randomly divided into a treatment group and a control group (n=46). The treatment group received endoscopic thyroidectomy through the anterior chest wall via the areolar approach, and the control group was treated with conventional open thyroidectomy. The two groups had similar immune function indices as well as thyroid hormone, serum calcium and phosphorus levels before surgery (P>0.05). After surgery, FT3 and FT4 levels significantly increased in both groups, whereas that of TSH significantly decreased (P<0.05). The levels of the two groups differed significantly on the postoperative 5th day (P<0.05). NK%, CD3+%, CD4+% and CD8+%, which significantly fluctuated on the postoperative 1st day in both groups (P<0.05), were basically recovered on the postoperative 5th day in the treatment group that had significantly different outcomes from those of the control group (P<0.05). On the postoperative 1st and 5th days, the treatment group had significantly lower serum calcium level and significantly higher serum phosphorus level than those of the control group (P<0.05). The surgeries were successfully performed for all patients. During three months of follow-up, the treatment group was significantly less prone to complications such as surgical site infection, recurrent laryngeal nerve injury, parathyroid crisis and hoarseness than the control group (P<0.05). For treatment of primary hyperparathyroidism, endoscopic thyroidectomy through the anterior chest wall via the areolar approach decreased the incidence rate of complications, as well as promoted the recovery of serum calcium and phosphorous levels, probably by only mildly affecting immune function and thyroid hormone levels.

[Purpose] This study investigated the effect of shoulder girdle strengthening, particularly the scapular muscles, on poststroke trunk alignment. [Subjects and Methods] The study involved 30 patients with residual hemiparesis following cerebrovascular stroke. Patient assessment included measuring shoulder muscle peak torque, scapular muscles peak force, spinal lateral deviation angle, and motor functional performance. Patients were randomly allocated either to the control group or the study group and received an 18-session strengthening program including active resisted exercises for shoulder abductors and external rotators in addition to trunk control exercises. The study group received additional strengthening exercises for the scapular muscles. [Results] The two groups showed significant improvement in strength of all shoulder and scapular muscles, with higher improvement in the study group. Similarly, the lateral spinal deviation angles significantly improved in both groups, with significantly higher improvement in the study group. Transfer activity, sitting balance, upper limb functions, and hand movements significantly improved in the two groups, with higher improvement in the latter two functions in the study group. [Conclusion] Strengthening of shoulder girdle muscles, particularly scapular muscles, can significantly contribute to improving the postural alignment of the trunk in patients with poststroke hemiparesis.

To explore the effect of parecoxib on cerebral infarction in rats and the regulatory mechanism on hypothalamus orexin neurons (orexin) and protein expression. 60 SD male rats were randomly divided into sham operation group, model group and treatment group (20 rats in each group). Cerebral infarction model was established by modified Longa method. Rats in the treatment group were given parecoxib (2.5 mg kg-1) in tail by intravenous injection, while both the sham operation group and the model group were given the equal volume of sterile PBS solution in the tail vein. Continuous intervention of 72h was carried out in the three groups. Immunofluorescence staining and Western blot were used to detect the expression of orexin neurons and orexin protein in the hypothalamus of rats, respectively. Immunofluorescence staining showed that the number of orexin positive cells in the model group was significantly less than that in the sham-operated group (p < 0.01). After treatment intervention, the number of orexin positive cells in the hypothalamus was significantly increased compared to that in model group (p < 0.01). Western blot analysis showed that compared with sham operation group, the expression of orexin in the hypothalamus of model group was significantly decreased (p < 0.01), whereas the expression of orexin protein was significantly elevated after parecoxib intervention (p < 0.01). Parecoxib plays a therapeutic effect on cerebral infarction by up-regulating the orexin neuron.

We investigated the effects of the relative increase in testosterone by dutasteride administration in patients with benign prostatic hyperplasia and hypogonadism on urinary symptoms or androgen-responsive general health. Seventy-six patients were enrolled, and were taking 0.5 mg dutasteride daily for 52 weeks. Before and after treatment, all participants underwent blood test, and body mass index, prostate volume (PV), bone mineral density (BMD), post-voiding residual (PVR) volume, and muscle volume were measured. All patients responded to the questionnaires: International prostatic symptom score (IPSS), Overactive Bladder Symptom score (OABSS). Patients were divided into two groups according to the increase rate of total testosterone (TT): group A, ≥20% increase in TT level; group B, <20% increase or decrease. Baseline TT and free testosterone (FT) levels were significantly lower in group A than group B. Both groups showed marked improvement in PV and PVR. Group A showed significant improvement in IPSS and OABSS with a significant increase of FT level, whereas group B showed no significant change. Dutasteride treatment contributed to a significant increase in BMD in group A. Dutasteride treatment significantly improved urinary symptoms and BMD in patients with low baseline serum TT and FT levels.

Traditional Korean American discipline is characterized by a lack of expression of affection and use of harsh discipline. The purpose of this study was to pilot test the effect of the Incredible Years Parenting Program among Korean American mothers. A randomized controlled experimental study design was used; 29 first-generation Korean American mothers of young children (3-8 years old) were randomly assigned to intervention (n=20) and control (n=9) groups. Intervention group mothers received a 12-week parenting program. Control group mothers did not receive the intervention. Mothers reported on discipline styles (positive, appropriate, and harsh), level of acculturation, and their child's outcomes (behavioral problems and social competence) at pre-, post-, and 1-year follow-up intervals. After completing the program, intervention group mothers significantly increased use of positive discipline as compared to control group mothers. Among intervention group mothers, high-acculturated mothers significantly increased appropriate discipline whereas low-acculturated mothers significantly decreased harsh discipline. In the 1-year follow-up, intervention group mothers maintained the significant effect for positive discipline. Providing this program appears to be a promising way of promoting positive discipline among Korean American mothers.

There is no conclusive evidence regarding the effect of fasting on different features in asthmatic patients. In the present study, the effect of Ramadan fasting in asthmatic patients and healthy control was studied. Haematological indices, inflammatory mediators, pulmonary function tests (PFT) and respiratory symptoms were evaluated in 15 asthmatic patients compared to 14 healthy matched control group before and after the one-month fasting period in Ramadan. The change in each parameter from the beginning to the end of Ramadan was calculated and referred to as "variation during Ramadan". The values of MCH, MCHC in both groups and monocyte counts in asthmatic patients, were significantly increased but platelet count was reduced in asthmatic and controls respectively compared to pre-Ramadan fasting period (P<0.05 to 0.001). Serum hs-CRP level in control and asthmatic groups was significantly reduced after Ramadan fasting month (P<0.001 for both groups). PFT values after Ramadan fasting month in both groups were non-significantly higher compared to pre-fasting values except FVC. Respiratory symptoms in asthmatic patients were non-significantly but wheeze-o was significantly reduced after Ramadan fasting period in asthma group (P<0.05). There was no significant difference in variations of different parameters during Ramadan fasting period between two groups, although reduction of hs-CRP in asthmatic group was non-significantly higher than control group. These results show that Ramadan fasting period has no negative impact on asthma and may have some positive effect on asthma severity with regard to reduction of hs-CRP concentration and chest wheeze.

Randomized controlled trial. Myofascial pain syndrome is characterized by myofascial trigger points (MTrPs) and fascia tenderness. We investigated the effects of manual pressure release (MPR) alone or in combination with taping (MPR/MKT) in subjects with MTrPs. Fifteen and 16 subjects received MPR and MPR/MKT respectively. Outcomes including Pressure pain threshold, muscle stiffness, mechanomyography were assessed at baseline, post-intervention and 7-days later. Pressure pain threshold improved significantly (d = 1.79, p < 0.005) in both groups. Significant improvement in muscle stiffness in the MPR/MKT group (0.27-0.49 mm) as compared to the MPR group (-0.02-0.23 mm). Mechanomyography amplitude in the MPR/MKT group was significantly higher than that of the MPR group (p < 0.05). MPR and MPR/MKT are effective in reducing pain in these subjects. MPR/MKT has a greater effect on muscle stiffness and contraction amplitude. IV. Copyright © 2016 Hanley & Belfus. Published by Elsevier Inc. All rights reserved.

To study the effects of an aquatic therapy program with different frequencies (2 vs 3 days per week) in chronic low back pain. [corrected] Non-randomized comparison trial. Sport and spa community health club. Fifty-four adults with chronic low back pain (48.9 ± 10.0 years). Eight-week aquatic therapy program. Pain (visual analog scale [VAS]), disability (Oswestry Disability Index), and quality of life (Short-Form Health Survey 36), body composition (weight, body mass index, body fat mass, body fat percentage, and skeletal muscle mass), and health-related fitness (sit and reach, handgrip strength, curl-up, Rockport 1-mile test). Both experimental groups presented significant improvements in low back pain and disability (P < 0.001) compared with control group. The 3 days/week group showed significantly greater benefits at VAS flexion and disability (P < 0.001) than the 2 days/week group. Regarding quality of life, both intervention groups presented significant differences for Physical Role (P < 0.05), Bodily Pain (P < 0.001), General Health (P = 0.012), and Standardized Physical Component (P < 0.001) compared with control group. Both experimental groups significantly improved all health-related fitness parameters (P < 0.01). The 3 days/week group showed significantly greater benefits at curl-up and heart rate (P < 0.001) than the 2 days/week group. No significant changes between treatment groups and control were found in body composition. Eight weeks of aquatic therapy program decrease levels of back pain and disability, increase quality of life, and improve health-related fitness in adults with chronic low back pain without effects in body composition. A dose-response effect was observed in some parameters, with greater benefits when exercising 3 days per week compared with 2 days. Wiley Periodicals, Inc.

To evaluate if ABO blood group and Rh factor have an effect on retinal and choroidal thickness. This study was designed prospectively. Retinal nerve fiber layer, retinal, and choroidal thicknesses were measured with spectral-domain optical coherence tomography. Retinal and choroidal thickness measurements (one subfoveal, three temporal, and three nasal) were obtained at 500-μm intervals up to 1500 μm with the caliper system. In this study, 109 male and 151 female, 260 individuals in total were included. There were 125 subjects in group A, 29 in group B, 34 in group AB, and 72 in group O. Rh factor was positive in 194 subjects and negative in 66. There was no significant difference between the groups regarding age (p = 0.667). The groups did not show any statistical difference in retinal nerve fiber layer thickness. There was significant difference found for mean retinal thickness at temporal 1000 μm when four groups were compared (p = 0.037). No statistically significant difference was detected for the remaining retinal and choroidal sectoral regions. The groups did not statistically significantly differ concerning Rh factor (p > 0.05). Although we found a significant difference in retinal thickness in the temporal retina between group B with group A and group O, we suggest that both blood group and Rh factor have no effect on retinal and choroidal thickness.

Liver fibrosis and subsequent cirrhosis is a major cause of death worldwide, but few effective antifibrotic therapies are reported. Whey-hydrolyzed peptide (WHP), a major peptide component of bovine milk, exerts anti-inflammatory effects in experimental models. A WHP-enriched diet is widely used for immunomodulating diets (IMD) in clinical fields. However, the effects of WHP on liver fibrosis remain unknown. The aim of this study was to investigate the antifibrotic effects of WHP in a rat cirrhosis model. Progressive liver fibrosis was induced by repeated intraperitoneal administration of dimethylnitrosamine (DMN) for 3 wk. Rats were fed either a WHP-enriched IMD (WHP group) or a control enteral diet (control group). The degree of liver fibrosis was compared between groups. Hepatocyte-protective effects were examined using hepatocytes isolated from rats fed a WHP diet. Reactive oxygen species and glutathione in liver tissue were investigated in the DMN cirrhosis model. Macroscopic and microscopic progression of liver fibrosis was remarkably suppressed in the WHP group. Elevated serum levels of liver enzymes and hyaluronic acid, and liver tissue hydroxyproline content were significantly attenuated in the WHP group. Necrotic hepatocyte rates with DMN challenge, isolated from rats fed a WHP-enriched IMD, were significantly lower. In the DMN cirrhosis model, reactive oxygen species were significantly lower, and glutathione was significantly higher in the WHP group's whole liver tissue. A WHP-enriched IMD effectively prevented progression of DMN-induced liver fibrosis in rats via a direct hepatocyte-protective effect and an antioxidant effect through glutathione synthesis.

To verify the effect of a new nasal spray made from natural medicines on allergic rhinitis in animals. Methods: The main natural medicines contained in Acusine nasal spray plus essential traditional Chinese medicine contained in drugs for allergic rhinitis in Chinese market were used. By preparation process of extraction of traditional Chinese medicine such as steam distillation, ethanol extraction, a new nasal spray made from natural medicines was prepared. In the meantime, 24 BALB/c mice and New Zealand white rabbits were used. Then, mice were randomly divided into four group; control group, beclomethasone dipropionate group, Acusine group and new spray group, 6 mice in each group. Moreover, the effect of the new nasal spray made on passive cutaneous anaphylaxis was conducted by detecting absorptions of Evan’s blue (620nm) in the four groups. Allergic rhinitis models in 40 New Zealand white rabbits were established. Consequently, 40 allergic rhinitis models in rabbits were randomly divided into control group, Acusine group and new spray group, 10 rabbits in each group. The four groups were sprayed nasally with saline, Acusine spray and new spray respectively, three times/d, for 30 days. The nasal resistances in the four groups were measured with a rhinoresistometer. Moreover, their nasal mucosa was taken for HE staining. Consequently, their pathological manifestations were observed. The results: Absorption of Evan’s blue (620nm) of new spray group will be found significantly lower than Acusine group (P<0.05) and will have no significantly difference compared with beclomethasone dipropionate group(P>0.05). On the other hand, absorption of Evan’s blue (620nm) of beclomethasone dipropionate group will be significantly lower than Acusine group (P<0.05). Moreover, The nasal resistances of new spray group will be significantly lower than Acusine group (P<0.05) and will have no significantly difference compared with beclomethasone dipropionate group (P».05). Moreover, the nasal resistances of beclomethasone dipropionate group will be significantly lower than Acusine group (P<0.05). While, the nasal mucosa of control group will be found typical as nasal mucosa of allergic rhinitis. However, the nasal mucosa of beclomethasone dipropionate group, Acusine group and new spray group will be better than control group. Of them, new spray group will be the best. The nasal mucosa of beclomethasone dipropionate group will show the manifestation of drug-induced rhinitis. The conclusion: The invented new spray will not only have a better treatment effect on allergic rhinitis, similar with beclomethasone dipropionate, than Acusine Nasal Spray but also will not leave side effect on nasal mucosa, compared with beclomethasone dipropionate. Thus, the new spray made from natural medicines can be further studied as a better prescription drug, rather than an OTC like Acusine Nasal Spray, to replace beclomethasone dipropionate nasal spray. However, further study that would be required to produce a more meaningful answer.

To investigate the myocardial protective effect of L-carnitine in children with hand, foot and mouth disease (HFMD) caused by Coxsackie A16 virus and possible mechanisms. A total of 60 HFMD children with abnormal myocardial enzyme after Coxsackie A16 virus infection were enrolled and randomly divided into L-carnitine group and fructose-1,6-diphosphate group (fructose group), with 30 children in each group. The two groups were given L-carnitine or fructose diphosphate in addition to antiviral and heat clearance treatment. Another 30 healthy children who underwent physical examination were enrolled as control group. The changes in myocardial zymogram, malondialdehyde (MDA), superoxide dismutase (SOD), and apoptosis factors sFas and sFasL after treatment were compared between groups. There was no significant difference in treatment response between the L-carnitine group and the fructose group (P>0.05). One child in the fructose group progressed to critical HFMD, which was not observed in the L-carnitine group. Before treatment, the L-carnitine group and the fructose group had significantly higher indices of myocardial zymogram and levels of MDA, sFas, and sFasL and a significantly lower level of SOD than the control group (P<0.05), while there were no significant differences in these indices between the L-carnitine group and the fructose group (P>0.05). After treatment, the L-carnitine group and the fructose group had significant reductions in the indices of myocardial zymogram and levels of MDA, sFas, and sFasL and a significant increase in the level of SOD (P<0.05); the fructose group had a significantly higher level of creatine kinase (CK) than the control group and the L-carnitine group, and there were no significant differences in other myocardial enzyme indices, MDA, sFas, and sFasL between the L-carnitine group and the fructose group, as well as between the L-carnitine and fructose groups and the control group (P>0.05). SOD level was negatively correlated with aspartate aminotransferase, lactate dehydrogenase (LDH), CK, and creatine kinase-MB (CK-MB) (r=-0.437, -0.364, -0.397, and -0.519 respectively; P<0.05), and MDA level was positively correlated with LDH and CK-MB (r=0.382 and 0.411 respectively; P<0.05). L-carnitine exerts a good myocardial protective effect in children with HFMD caused by Coxsackie A16 virus, possibly by clearing oxygen radicals and inhibiting cardiomyocyte apoptosis.

To study the effects of person-centred care provided to patients with acute coronary syndrome, using four different health-related outcome measures. Also, to examine the performance of these outcomes when measuring person-centred care. The data used in this study consists of primary data from a multicentre randomized parallel group, controlled intervention study for patients with acute coronary syndrome at Sahlgrenska University Hospital in Gothenburg, Sweden. The intervention and control group consisted of 94 and 105 patients, respectively. The effect of the intervention on health-related outcomes was estimated, controlling for socio-economic and disease-related variables. Patients in the intervention group reported significantly higher general self-efficacy than those in the control group six months after intervention start-up. Moreover, the intervention group returned to work in a greater extent than controls; their physical activity level had increased more and they had a higher EQ-5D score, meaning higher health-related quality of life. These latter effects are not significant but are all pointing towards the beneficial effects of person-centred care. All the effects were estimated while controlling for important socio-economic and disease-related variables. The effectiveness of person-centred care varies between different outcomes considered. A statistically significant beneficial effect was found for one of the four outcome measures (self-efficacy). The other measures all captured beneficial, but not significant, effects.

Ankaferd blood stopper (ABS) is a mixture of certain ratios of 5 different plant roots (Thymus vulgaris, Glycyrrhiza glabra, Vitis vinifera, Alpinia officinarum, and Urtica dioica). The aim of this study is to evaluate the histopathological effects of ABS on articular cartilage in vitro. Twenty-one albino Sprague Dawley rats were randomly allocated to 3 groups: 0.1 mL of saline was injected in the first group, 0.1 mL of ABS was injected in the second group, and 0.1 mL of blood and 0.1 mL of ABS were injected in the third group. One month later all rats were sacrificed. Specimens were obtained for histopathological evaluation. Significant results were detected in the groups with respect to International Cartilage Repair Society and synovial proliferation scores (P < 0.05 and P < 0.01). According to inflammatory cell infiltration and fibrin formation scores, there was no significant difference between group 1 and group 2 (P < 0.01), although there was significant difference between group 3 and the other groups (P > 0.05). ABS and hemarthrosis had toxic effects on knee cartilage. The side effects were increased with the combination of hemarthrosis and ABS. As a result, ABS had unexpected effects on experimental hemarthrosis.

[Purpose] This research was conducted to investigate the effects of modified trampoline training on the balance, gait, and falls efficacy of stroke patients. [Subjects] Twenty-four stroke patients participated in this study. The subjects were randomly allocated to one of two groups: the trampoline group (n=12) or the control group (n=12). [Methods] Both groups participated in conventional physical therapy for thirty minutes per day, three times a week for six weeks. The trampoline group also took part in trampoline training for thirty minutes per day, three times a week for six weeks. We evaluated balance (Berg balance scale, timed up and go test), gait (dynamic gait index), and falls efficacy (falls efficacy scale-K) to confirm the effects of the intervention. [Results] Both the trampoline and the control group showed significant improvements in balance, gait, and falls efficacy compared to before the intervention, and the improvements were significantly greater in the trampoline group than in the control group. [Conclusion] Modified trampoline training resulted in significantly improved balance, dynamic gait, and falls efficacy of stroke patients compared to the control group. These results suggest that modified trampoline training is feasible and effective at improving balance, dynamic gait, and falls efficacy after stroke. PMID:26696696

The purpose of this study is to compare the effects of spinal and epidural anesthesia on a rat transverse rectus abdominus myocutaneous flap ischemia-reperfusion injury model.Forty Sprague-Dawley rats were divided into 4 experimental groups: group I (n = 10), sham group; group II (n = 10), control group; group III (n = 10), epidural group; and group IV (n = 10), spinal group. After the elevation of the transverse rectus abdominus myocutaneous flaps, all groups except for the sham group were subjected to normothermic no-flow ischemia for 4 hours, followed by a reperfusion period of 2 hours. At the end of the reperfusion period, biochemical and histopathological evaluations were performed on tissue samples.Although there was no significant difference concerning the malonyldialdehyde, nitric oxide, and paraoxonase levels in the spinal and epidural groups, the total antioxidant state levels were significantly increased, and the total oxidative stress levels were significantly decreased in the epidural group in comparison to the spinal group. The pathological evaluation showed that findings related to inflammation, nuclear change rates and hyalinization were significantly higher in the spinal group compared with the epidural group.Epidural anesthesia can be considered as a more suitable method that enables a decrease in ischemia-reperfusion injuries in the muscle flaps.

Micro-vibration culture system was examined to determine the effects on mouse and human embryo development and possible improvement of clinical outcomes in poor responders. The embryonic development rates and cell numbers of blastocysts were compared between a static culture group (n = 178) and a micro-vibration culture group (n = 181) in mice. The embryonic development rates and clinical results were compared between a static culture group (n = 159 cycles) and a micro-vibration culture group (n = 166 cycles) in poor responders. A micro-vibrator was set at a frequency of 42 Hz, 5 s/60 min duration for mouse and human embryo development. The embryonic development rate was significantly improved in the micro-vibration culture group in mice (p < 0.05). The cell numbers of mouse blastocysts were significantly higher in the micro-vibration group than in the static culture group (p < 0.05). In the poor responders, the rate of high grade embryos was not significantly improved in the micro-vibration culture group on day 3. However, the optimal embryonic development rate on day 5 was improved in the micro-vibration group, and the total pregnancy rate and implantation rate were significantly higher in the micro-vibration group than in the static culture group (p < 0.05). Micro-vibration culture methods have a beneficial effect on embryonic development in mouse embryos. In poor responders, the embryo development rate was improved to a limited extent under the micro-vibration culture conditions, but the clinical results were significantly improved.

One of the effects of diabetes mellitus (DM), peripheral neuropathy, affects the sensation in the feet and can increase the chance of falling. The purpose of the study was to investigate the effect of 8 weeks of Tai Chi (TC) training combined with mental imagery (MI) on improving balance in people with diabetes and an age matched control group. Seventeen healthy subjects and 12 diabetic sedentary subjects ranging from 40-80 years of age were recruited. All subjects in both groups attended a Yang style of TC class using MI strategies, 2 sessions a week for 8 weeks. Each session was one hour long. Measures were taken using a balance platform test, an Activities-specific Balance Confidence (ABC) Scale, a one leg standing test (OLS), functional reach test (FRT) and hemoglobin A1C. These measures were taken twice, pre and post-study, for both groups. Both groups experienced significant improvements in ABC, OLS, FRT (P<0.01) after completing 8 weeks of TC exercise with no significant improvement between groups. Subjects using the balance platform test demonstrated improvement in balance in all different tasks with no significant change between groups. There was no significant change in HbA1C for the diabetic group. All results showed an improvement in balance in the diabetic and the control groups; however, no significant difference between the groups was observed. Since the DM group had more problems with balance impairment at baseline than the control, the diabetic group showed the most benefit from the TC exercise.

To compare tourniquet application and epinephrine injection for hemostasis during hypospadias surgery in terms of bleeding and complications. Between April 2013 and September 2014, patients who were admitted for hypospadias repair were divided by random allocation into either a diluted epinephrine injection (DE) group or tourniquet application (T) group for hemostasis during the procedure. In the T group, a rubber band was applied at the base of the penis after skin dissection, and in the DE group, epinephrine 1/100,000 was injected along the incision lines. The patients' ages, urethral defect lengths, pre-operative, intraoperative and postoperative variables were compared between the two groups. A total of 70 patients (35 in each group) were enrolled into the study. The mean ages and preoperative variables were not significantly different. Average blood loss was 23.51 ± 15.36 cc in the tourniquet group and 15.99 ± 10.00 cc in the epinephrine group, and was significantly higher in tourniquet group (P = 0.022); however, the mean operative time was not significantly different. Postoperative complications, described as Clavian classification, were reported in eight patients (23%) in the T group and 10 patients (30%) in the DE group, which was not significantly different. Epinephrine injections minimize operative bleeding without significant harmful effects on postoperative outcomes; therefore, it could be considered to be a safe and effective method for preparation of a bloodless field during hypospadias surgery.

Problems like postoperative pain are still common phenomena after general anesthesia. Oxycodone hydrochloride is a semisynthetic opioid with a safe and excellent therapeutic effect on visceral pain. Flurbiprofen axetil has the efficacy of targeted analgesia. We hypothesize that different doses of oxycodone hydrochloride combined with flurbiprofen axetil would generate great results on postoperative intravenous analgesia in lower abdominal patients. In the clinical trial, 90 American Society of Anesthesiologists I or II patients scheduled for elective general anesthesia were randomly divided into 3 groups, 30 cases in each group. Group I: oxycodone hydrochloride 0.5 mg/kg + flurbiprofen axetil 150 mg, group II: oxycodone hydrochloride 0.75 mg/kg + flurbiprofen axetil 150 mg, group III: oxycodone hydrochloride 1.0 mg/kg + flurbiprofen axetil 150 mg. Dilute them with 0.9% saline to 150 mL, respectively, with the background dose of 2 mL/h, patient-controlled analgesia 2 mL per time, with an interval of 10 min, and the loading dose of 0.1 mL/kg. Record the preoperative situation, 24 h (T0) before surgery, postoperative situation, 1 h (T1), 4 h (T2), 8 h (T3), 12 h (T4), 24 h (T5), 48 h (T6), 72 h (T7) after the surgery, including the mean arterial pressure, heart rate, saturation of pulse oximetry, static and dynamic pain rating (NRS) and Ramsay sedation score, effective pressing and total pressing ratio (referred to as the pressing ratio), patient satisfaction, and occurrence of adverse reactions. There was no significant statistic difference in mean arterial blood pressure, heart rate, arterial oxygen saturation, and adverse reactions among the 2 groups at each time point (P > .05). Compared with group I, the static NRS rating in group II and group III were significantly lower than that in group I (P < .05) from T1 to T5. The dynamic NRS rating of group II from T1 to T4 and that of group III from T1 to T5 were significantly lower (P < .05). The effective pressing and total pressing ratio was significantly higher (P < .05). There was no significant statistic difference between group II and group III in NRS rating and the effective pressing and total pressing ratio (P > .05). Compared with group III, the Ramsay sedation scores of group I and group II were significantly lower from T1 to T4 (P < .05). The dose of 0.75 mg/kg oxycodone hydrochloride combined with flurbiprofen axetil can provide safe and effective postoperative analgesia for lower abdominal patients, with fewer adverse reactions.

This study evaluated a system thinking-based simulation program for the care of patients with congestive heart failure. Participants were 67 undergraduate nursing students from a nursing college in Seoul, South Korea. The experimental group was given a 4-hour system-thinking program and a 2-hour simulation program, whereas the control group had a 4-hour case study and a 2-hour simulation program. There were significant improvements in critical thinking in both groups, but no significant group differences between educational methods (F = 3.26, P = .076). Problem-solving ability in the experimental group was significantly higher than in the control group (F = 5.04, P = .028). Clinical competency skills in the experimental group were higher than in the control group (t = 2.12, P = .038). A system thinking-based simulation program is a more effective learning method in terms of problem-solving ability and clinical competency skills compared to the existing simulation program. Further research using a longitudinal study is needed to test the long-term effect of the intervention and apply it to the nursing curriculum.

Pulmonary complications of exposure to sulfur mustard (SM) gas range from no effect or mild symptoms to severe bronchial stenosis. In the present study, the protective effect of vitamin E on the lung inflammation of SM-exposed guinea pigs was examined. Guinea pigs (n = 5 for each group) were exposed to ethanol (control group), 40 mg/m 3 inhaled SM (SME group), SME treated with vitamin E (SME + E), SME treated with dexamethasone (SME + D), and SME treated with both treatments (SME + E + D). Pathological evaluation of the lung was done 14 days postexposure. The epithelial desquamation of trachea and other pathologic changes in the lung of the SME group were significantly higher than those in the control group. Furthermore, the pathological changes of trachea and lung in the SME + E and SME + E + D groups were significantly improved compared with those of SME group. In addition, the pathological changes of trachea and lung of SME + E and SME + E + D animals were significantly less than those of SME + D group. © The Author(s) 2015.

The purpose of this study was to determine whether α-lipoic acid and fisetin have protective effects against cataract in a streptozotocin-induced experimental cataract model. Twenty-eight male BALB/C mice were made diabetic by the intraperitoneal administration of streptozotocin (200 mg/kg). Three weeks after induction of diabetes, mice were divided randomly into 4 groups in which each group contained 7 mice; fisetin-treated group (group 1), α-lipoic acid-treated group (group 2), fisetin placebo group (group 3), α-lipoic acid placebo group (group 4). Fisetin and α-lipoic acid were administered intraperitoneally weekly for 5 weeks. Cataract development was assessed at the end of 8 weeks by slit lamp examination, and cataract formation was graded using a scale. All groups developed at least grade 1 cataract formation. In the fisetin-treated group, the cataract stages were significantly lower than in the placebo group (p = 0.02). In the α-lipoic acid-treated group, the cataract stages were lower than in the placebo group but it did not reach to a significant value. Both fisetin and α-lipoic acid had a protective effect on cataract development in a streptozotocin-induced experimental cataract model. The protective effect of fisetin appears as though more effective than α-lipoic acid.

In this prospective study, we compared the efficacy and side effects of indomethacin, ibuprofen, and paracetamol in patent ductus arteriosus (PDA) closure in preterm neonates. Three hundred preterm neonates with hemodynamically significant PDA (hs-PDA) admitted at our neonatal intensive care unit were enrolled in the study. They were randomized into three groups. Group I (paracetamol group) received 15 mg/kg/6 h IV paracetamol infusion for 3 days. Group II (ibuprofen group) received 10 mg/kg IV ibuprofen infusion followed by 5 mg/kg/day for 2 days. Group III (indomethacin group) received 0.2 mg/kg/12 h indomethacin IV infusion for three doses. Laboratory investigations such as renal function test, liver function test, complete blood count, and blood gases were conducted in addition to echocardiographic examinations. All investigations were done before and 3 days after treatment. There was no significant difference between all groups regarding efficacy of PDA closure (P = 0.868). There was a significant increase in serum creatinine levels and serum blood urea nitrogen (BUN) in the ibuprofen and indomethacin groups (P < 0.001). There was a significant reduction in platelet count and urine output (UOP) in both ibuprofen and indomethacin groups (P < 0.001). There was a significant increase in bilirubin levels in only the ibuprofen group (P = 0.003). No significant difference of hemoglobin (HB) level or liver enzymes in all groups (P > 0.05). Ventilatory settings improved significantly in patients with successful closure of PDA than those with failed PDA closure (P < 0.001). Paracetamol is as effective as indomethacin and ibuprofen in closure of PDA in preterm neonates and has less side effects mainly on renal function, platelet count, and GIT bleeding. What is Known: • Hemodynamically significant patent ductus arteriosus has many complications for preterm and low birth weight neonates and better to be closed. Many drugs were used for medical closure of PDA e.g. indomethacin, ibuprofen and recently paracetamol. Many studies compare safety and efficacy of paracetamol with either indomethacin or ibuprofen. What is New: • It is the first large study that compares the efficacy and side effects of the three drugs in one study.

This study aimed to compare the effects between group discussion and educational booklet on nursing students' attitude and practice toward patient privacy in Iran. A two-group, pre-test and post-test design study was conducted in 2015. The study was conducted on 60 nursing students in Kashan, Iran who were randomly allocated into two groups to be trained on patient privacy either through group discussion or by an educational booklet. The students' attitude and practice was assessed before and after the education using a questionnaire and a checklist. Data analysis was performed through paired t-test, Wilcoxon signed ranks test, and independent samples t-tests. Before the intervention, no significant difference was found between the group designated to group discussion and that designated to the educational booklet in the mean overall score of attitude (P=0.303) and practice (P=0.493) toward patient privacy. After the intervention, the mean attitude score significantly increased in the two groups (P=0.001). Moreover, the students' practice score increased in the discussion group while it did not significantly change in the booklet group (P=0.001). Both methods were effective on the students' attitude; however, the educational booklet did not affect their practice toward patient privacy. Group discussion can effectively improve the students' attitude and practice toward patient privacy.

The aims of the study were to determine: 1) how mucociliary activity in acute bacterial rhinosinusitis is affected; 2) how this activity is changed by therapy; 3) the effects of topical agents on mucociliary clearance, and 4) the most appropriate topical agent(s) to be used in the therapy of sinusitis. Five groups of patients with acute bacterial rhinosinusitis were studied prospectively. All patients had 500 mg oral amoxicillin and 125 mg oral clavulanic acid preparations given three times daily for 3 weeks. According to the topical agent applications, these groups included: group I (n = 12), no topical treatment was given; group II (n = 14), two puffs for each nostril once daily of 50 microg/100 mL fluticasone propionate was given; group III (n = 9), one puff for each nostril three times daily of 0.05% oxymetazoline was given; group IV (n =12), 3% sodium chloride (NaCl) (buffered to pH 6.5-7 at room temperature) was given; and group V (n =13), 10-mL solutions of 0.9% NaCl (buffered to pH 6.5--7 at room temperature) were given for nasal irrigations three times daily. All patients had medication for 3 weeks and were controlled each week. The saccharin method was used to measure nasal mucociliary clearance. To investigate the early effects of the topical agents for groups II to V, an additional test was repeated 20 minutes after the basal mucociliary clearance recordings. The test was repeated in the first, second, and third weeks of the treatment. The mucociliary clearance was significantly slower in the acute bacterial rhinosinusitis group than in the control group. There was no significant difference between the basal mucociliary clearance and the 20th minute mucociliary clearance of the fluticasone propionate and 0.9% NaCl solution groups. The mean values of the basal and the 20 minute's mucociliary clearance of the oxymetazoline group were 24.72 +/- 6.16 and 15.5 +/- 7.45 minutes, respectively, which were statistically significant. The mean values of the basal and the 20th minute mucociliary clearance of the 3% NaCl solution groups were 19.45 +/- 9.35 and 15.45 +/- 8.20 minutes, respectively, which were also statistically significant. In the first group (without topical treatment), the basal mucociliary clearance became significantly shorter after the second week of treatment. In the first and second weeks of the treatment of the oxymetazoline group, the mucociliary clearance did not change significantly, but after the third week the mucociliary clearance was significantly shorter. In the 3% NaCl solution group, significant improvement began from the first week and continued through the third week. Comparing the basal and the third weeks' mucociliary clearance values among the groups, the oxymetazoline and 3% NaCl solution groups revealed more significant improvement than the other groups, but this improvement was not different from the improvement of group I. There was still a statistically significant difference in the mucociliary clearance of the post-treatment sinusitis groups from the control group. The oxymetazoline and 3% NaCl solution groups seemed to be more effective in mucociliary clearance, but there was no significant difference in improvement among the groups. The improvement of acute bacterial rhinosinusitis takes more than 3 weeks, according to the mucociliary clearance values of the groups.

To evaluate the effectiveness of the combination of vitrectomy with kallidinogenase for diabetic macular edema (DME). This study was designed as a prospective, randomized, multicenter study comparing 19 eyes of 19 patients who received 150 units of kallidinogenase administered a day for 52 weeks from the day after vitrectomy (study group) with 20 eyes of 20 patients who received no kallidinogenase (control group). The main outcome measurements included logMAR visual acuity and central foveal thickness (CFT) before surgery and at 3, 6, 9, and 12 months after vitrectomy. During follow-up, 11 patients dropped out (six in the study group and five in the control group), leaving 28 eyes in 28 patients for analysis (13 in the study group and 15 in the control group). Visual acuity improved significantly at 12 months in both groups compared with before surgery. The degree of improvement did not differ significantly between the groups. At 12 months, the mean CFT decreased significantly in both groups, with no significant difference in the rate of change between the two groups. In the study group, the visual acuity and CFT significantly improved from 3 to 12 months and from 6 to 12 months, whereas these parameters did not continue to improve in the control group after 6 months (for visual acuity) or 3 months (for CFT). After vitrectomy for DME, visual acuity and CFT improved significantly in both groups, but only patients treated with kallidinogenase continued to have significant improvement throughout the study period.

Although unripe plantain (Musa paradisiaca) and ginger (Zingiber officinale) are used as single plants to manage diabetes mellitus in Nigeria, the possibility of combining them in a typical diabetic diet and the glycemic response elicited as a result of such combination has not been investigated. To determine the effect of unripe plantain and ginger on serum total proteins, albumin, creatinine and urea levels of streptozotocin induced diabetic rats. Twenty four male albino rats were used and were divided into 4 groups of 6 rats each. Group 1 (non-diabetic) received standard rat feeds; Group 2 (diabetic) received standard rat feeds; Group 3 received unripe plantain pellets and Group 4 received unripe plantain+ginger pellets. There were significant increases (P=0.045) of both serum urea and creatinine, but significant decreases (P=0.045) of both serum total protein and albumin levels, in Group 2 rats compared with Group 1. There were significant decreases (P=0.033) of both serum urea and creatinine levels of Group 3 and 4 rats compared with Group 2. In addition, there were significant increases of both serum total protein and albumin levels (P=0.033) in Group 3 rats compared with Group 2, but the comparison of serum total protein and albumin levels between Group 4 and Group 2 did not reach the significant level (P=0.056 and P=0.065 for serum total protein and albumin levels, respectively. Combination of unripe plantain and ginger at the ratio used in the management of renal dysfunction in diabetics was not very effective compared with unripe plantain alone.

To investigate the therapeutic effects of the aqueous extract of Petroselinum Sativum aerial parts and roots on kidney calculi. Thirty-six male Wistar rats were randomly assigned into 6 groups and treated for 30 days. Group A served as normal control and group B received 1% ethylene glycol in drinking water. Groups C, D, E, and F received 1% ethylene glycol from day 0 and were used as the treatment subjects. Rats in groups C and D received 200 and 600 mg/kg body weight of aerial parts aqueous extract, respectively, and those in groups E and F received 200 and 600 mg/kg body weight of root aqueous extract in drinking water, respectively, from the 14th day of the experiment. On the 14th and 30th days of the experiment, serum level of magnesium (1.71 ± 0.12 and 3.81 ± 0.25, respectively) decreased significantly while serum level of calcium (10.45 ± 0.26 and 11.33 ± 0.18, respectively) increased significantly in group B compared with the control group (14th day: magnesium = 2.87 ± 0.17 and calcium = 8.80 ± 0.00 and 30th day: magnesium = 6.01 ± 0.00 and calcium = 8.30 ± 0.22; P < .001). In the treatment groups of C, D, E, and F, the number of deposits decreased significantly compared with group B on the 30th day (P < .001). The weight of the kidneys increased significantly in group B (2.01 ± 0.17) compared with the control group (1.52 ± 0.07) and decreased significantly in treatment groups (P < .05). Petroselinum Sativum has a therapeutic effect on calcium oxalate stones in rats with nephrolithiasis and reduces the number of calcium oxalate deposits.

Dexmedetomidine (Dex) is a novel Alpha 2-adrenoceptor agonist. It decreases sympathetic tone and attenuates the stress responses to anesthesia and surgery. People exposed to cold suffer unpleasant thermal pain, which is experienced as stress and causes the release of noradrenaline from the sympathetic terminals. The present study investigated the effects of cold stress and dexmedetomidine on chronic constriction injury (CCI) model of the sciatic nerve in rats. Sixty four male Wistar rats were divided into seven groups of eight rats each: repeated cold stress (RCS) group, sham RCS group, CCI group, sham CCI group, Dex-treated group received a single dose of Dex (5 μg/kg), CCI+Dex group, CCI+RCS group. Interleukin-6 (IL-6) and tumor necrosis factor- alpha (TNF-α) levels in the serum were measured by enzyme-linked immunosorbent assay. The mean body weight of CCI, RCS, CCI+RCS, CCI+Dex and RCS+Dex groups decreased significantly compared with pre-values. Dexmedetomidine and CCI caused significant changes of the systolic, diastolic and mean blood pressure. Both RCS and CCI groups showed significant decreased of reaction time in the hot plate test. The RCS and CCI groups demonstrated a significant mechanical hyperalgesia, while pain threshold was increased in the RCS+Dex group. A significant decrease of serum IL-6 and TNF-α was demonstrated in CCI+RCS and CCI+Dex groups. The therapeutic effectiveness of dexmedetomidine in neuropathic pain may be through inhibition of proinflammatory cytokines, primarily IL-6 and TNF-α. Moreover, cold stress may result in increased resistance to neuropathic pain. Copyright © 2016 Elsevier B.V. All rights reserved.

To determine the effects of a new exercise training regimen, i.e. coordination and manipulation therapy (CMT), on motor, balance, and cardiac functions in patients with Parkinson disease (PD). We divided 36 PD patients into the CMT (n = 22) and control (n = 14) groups. The patients in the CMT group performed dry-land swimming (imitation of the breaststroke) and paraspinal muscle stretching for 30 min/workday for 1 year. The control subjects did not exercise regularly. The same medication regimen was maintained in both groups during the study. Clinical characteristics, Unified Parkinson's Disease Rating Scale (UPDRS) scores, Berg balance scale (BBS) scores, mechanical balance measurements, timed up and go (TUG) test, and left ventricular ejection fraction (LVEF) were compared at 0 (baseline), 6, and 12 months. Biochemical test results were compared at 0 and 12 months. The primary outcome was motor ability. The secondary outcome was cardiac function. In the CMT group, UPDRS scores significantly improved, TUG test time and step number significantly decreased, BBS scores significantly increased, and most mechanical balance measurements significantly improved after 1 year of regular exercise therapy (all p < 0.05). In the control group, UPDRS scores significantly deteriorated, TUG test time and step number significantly increased, BBS scores significantly decreased, and most mechanical balance measurements significantly worsened after 1 year (all P < 0.05). LVEF improved in the CMT group only (P = 0.01). This preliminary study suggests that CMT effectively improved mobility disorder, balance, and cardiac function in PD patients over a 1-year period.

The objective of this study was to observe the antihypertensive effect of losartan and levamlodipine besylate on insulin resistance in patients with essential hypertension (EH) combined with isolated impaired fasting glucose (i-IFG). Patients (n=244) were randomly assigned to losartan potassium tablets (50-100 mg per day) or levamlodipine besylate tablets (2.5-5.0 mg per day) for intensive antihypertensive treatment with no lifestyle interventions for 3 years. The changes in fasting plasma glucose, fasting insulin (FINS) and insulin sensitivity index (ISI) from before to after treatment were observed. Blood pressure (BP) in each group was significantly reduced by treatment (P<0.05). After 12 months of treatment, the FINS level in the losartan potassium group was significantly decreased and ISI was significantly increased compared with before treatment (P<0.05) and compared with the levamlodipine besylate group (P<0.05). After 24 and 36 months of treatment, FINS was significantly decreased and ISI was significantly improved in both groups compared with baseline (P<0.05), and there was no difference between the groups (P>0.05). The incidence of new-onset diabetes mellitus was not significantly different between two groups. The antihypertensive effect of losartan and levamlodipine besylate could amoliorate insulin resistance in patients with EH combined with i-IFG. The improvement of insulin resistance by losartan potassium at 12 months might be better than that by levamlodipine besylate; however, after 24 and 36 months of follow-up, both agents significantly alleviated insulin resistance. These results suggest that the effects of these two drugs on insulin resistance are not significantly different.

The purpose of this study was to examine the effects of a facial muscle exercise program including facial massage on the facial muscle function, subjective symptoms related to paralysis and depression in patients with facial palsy. This study was a quasi-experimental research with a non-equivalent control group non-synchronized design. Participants were 70 patients with facial palsy (experimental group 35, control group 35). For the experimental group, the facial muscular exercise program including facial massage was performed 20 minutes a day, 3 times a week for two weeks. Data were analyzed using descriptive statistics, χ²-test, Fisher's exact test and independent sample t-test with the SPSS 18.0 program. Facial muscular function of the experimental group improved significantly compared to the control group. There was no significant difference in symptoms related to paralysis between the experimental group and control group. The level of depression in the experimental group was significantly lower than the control group. Results suggest that a facial muscle exercise program including facial massage is an effective nursing intervention to improve facial muscle function and decrease depression in patients with facial palsy.

To investigate the effect of silymarin on oxidative stress and hepatic injury induced by obstructive jaundice in an experimental model. Thirty Wistar-Albino type female rats were divided into 3 groups each including 10 rats. Only laparotomy was performed in group 1. Bile duct ligation was performed in group 2. In group 3, bile duct ligation was performed and orogastic silymarin 300 mg/kg/day dose was given for seven days. At the end of seven days, rats were sacrificed. The blood and liver tissue samples were taken to be examined biochemically and histopathologically. The plasma and liver levels of malondialdehyde were significantly lower in silymarin group than in the bile duct ligated group. Although liver levels of GSH were significantly higher in silymarin group than in the bile duct ligated group, there was no significant difference between the plasma GSH levels of these groups. In silymarin group; the enlargement of hepatocytes, dilatation of canaliculi and the edema were regressed. Silymarin diminished the harmful effects of obstructive jaundice on liver.

To investigate the antimicrobial, immunological and healing effects of Melipona scutellaris honey on infected wounds of rat skin. Twenty four Wistar rats were distributed in four groups (6-each). The uninfected skin wounds of group I rats were treated daily with saline for 7 days. Uninfected wounds (group II) rats were treated with honey. In group III (treated with saline) and group IV (treated with honey) wounds were inoculated with MRSA ATTC43300. The first bacterial culture was performed 24 hours later. In the 7th day new culture was done, and wound biopsies were used for cytokines dosage and histopathology. In group I and III rats the CFU/g count of S. aureus in wounds was zero. In group II rats the CFU/g counts in the wound tissue were significantly higher than in wounds of group IV rats. The density histopathological parameters and the expression of TNF-α, IL1-β, Il-6 were significantly higher on wounds of group IV then in the other groups. Honey of Melipona scutellaris was effective in the management of infected wounds, by significant bacterial growth inhibition, enhancement of cytokine expression, and positively influenced the wound repair.

This pilot study was conducted to determine the effectiveness of Healing Touch on anxiety, stress, pain, pain medication usage, and selected physiological measures of hospitalized adults with sickle cell disease experiencing a vaso-occlusive pain episode. Healing Touch sessions were administered for 30 minutes on four consecutive days, and the self-reported data on anxiety, stress, pain, and the selected physiological data were collected while controlling for music and presence. A parallel-group randomized control trial comparing the effects of Healing Touch with Music (HTM) to Attention Control with Music (ACM). Due to the small sample size, there were no statistically significant changes in any between-group comparisons, except for present pain on Day 4 for the ACM group. For both groups, the within-group comparison showed a nonsignificant reduction in physiological parameters, a statistically significant reduction in anxiety and stress for the ACM group after Day 4, and a statistically significant reduction in stress in the HTM group after Days 2 and 4. The pre- to postintervention reductions in present pain were greater in the HTM group across all 4 days, but the only statistically significant within groups findings were in the HTM group (p < .01) on Day 1. Further research is needed.

Our aim is to investigate the effects of three therapeutic approaches in the chronic low back pain on pain, spinal mobility, disability, psychological state, and aerobic capacity. Sixty patients with chronic low back pain were randomized to three groups: group 1, aerobic exercise + home exercise; group 2, physical therapy (hot pack, ultrasound, TENS) + home exercise; group 3, home exercise only. Spinal mobility, pain severity, disability, and psychological disturbance of the patients were assessed before and after the treatment and at 1-month follow-up. Aerobic capacities of the patients were measured before and after treatment. All of the groups showed similar decrease in pain after the treatment and at 1-month follow-up, and there was no significant difference between the groups. In group 2, a significant decrease in Beck Depression Inventory scores was observed with treatment. At 1-month follow-up, group 1 and 2 showed significant decreases in General Health Assessment Questionnaire scores. In group 2, there was also a significant improvement in Roland Morris Disability scores. There were similar improvements in exercise test duration and the MET levels in all the three groups. All of the three therapeutic approaches were found to be effective in diminishing pain and thus increasing aerobic capacity in patients with chronic low back pain. On the other hand, physical therapy + home exercise was found to be more effective regarding disability and psychological disturbance.

Designing an intervention to increase physical activity is important to be based on the health care settings resources and be acceptable by the subject group. This study was designed to assess and compare the effect of the goal setting strategy with a group education method on increasing the physical activity of mothers of children aged 1 to 5. Mothers who had at least one child of 1-5 years were randomized into two groups. The effect of 1) goal-setting strategy and 2) group education method on increasing physical activity was assessed and compared 1 month and 3 months after the intervention. Also, the weight, height, body mass index (BMI), waist and hip circumference, and well-being were compared between the two groups before and after the intervention. Physical activity level increased significantly after the intervention in the goal-setting group and it was significantly different between the two groups after intervention (P < 0.05). BMI, waist circumference, hip circumference, and well-being score were significantly different in the goal-setting group after the intervention. In the group education method, only the well-being score improved significantly (P < 0.05). Our study presented the effects of using the goal-setting strategy to boost physical activity, improving the state of well-being and decreasing BMI, waist, and hip circumference.

The aim of this study was to examine the effectiveness of Progressive Muscle Relaxation (PMR) as part of a Worksite Health Promotion Program on self-perceived stress, anxiety and depression among male automotive assembly-line workers through a quasi-experimental trial. Two assembly plants were chosen with one receiving PMR therapy and the other Pamphlets. Intention-to-treat analysis was conducted to test the effectiveness of the relaxation therapy. Stress, Depression and Anxiety levels were measured using the shortened DASS-21 questionnaire. Data were analyzed using Chi-square, Independent sample t test and Repeated-measures analysis of variance to test the significance of the effects of intervention (time * group) for the measures of Stress, Depression and Anxiety. Significant favourable intervention effects on stress were found in the PMR group (Effect size=0.6) as compared to the Pamphlet group (Effect size=0.2). There was a significant group *time interaction effect (p<0.001) on Stress levels. Depression and Anxiety levels were minimal at baseline in both the groups with mild or no reduction in levels. The improvement in stress levels showed the potential of PMR therapy as a coping strategy at the workplace. Further research in this field is necessary to examine the beneficial effects of coping strategies in the workplace. PMID:26726829

The effect of different exercise programs on cervical flexor muscles dimensions in patients with chronic neck pain is yet to be demonstrated. The purpose of this study was to assess the effect of two exercise programs; craniocervical flexion (CCF) and cervical flexion (CF), on flexor muscles dimensions in patients with chronic neck pain. Following ethical approval, 60 patients were randomly assigned into either a CCF group or a CF group. Patients in the CCF group were given CCF exercises and those in the CF group received CF exercises. All patients received interventions for a period of ten weeks. Pain intensity and functional disability were assessed using numerical pain rate scale and neck disability index, respectively. Dimensions of longus colli (LC) and sternoclidomastoid (SCM) muscles were measured using ultrasonography (US). All measurements were taken before and after interventions. Following intervention, the CCF group demonstrated a significant increase in LC muscle dimensions including cross sectional area, width and thickness compared with the CF group. A statistically significant increase was found on SCM thickness in the CF group. Following intervention, SCM thickness measurement in the CCF group showed no significant changes. Statistically significant decrease on pain intensity and disability were also found in both groups. Present findings demonstrated that craniocervical flexion program which specifically recruiting deep cervical flexor muscles increased LC muscle dimension significantly and CF program as an endurance training program increased SCM thickness.

We evaluated an epilepsy education programme based on text messaging (SMS). Epilepsy outpatients from three hospitals in Malaysia were randomised into two groups: intervention and control. Patients in the control group were supplied with printed epilepsy educational material while those in the intervention group also received text messages from the Mobile Epilepsy Educational System (MEES). A total of 136 patients completed the study (mean age 31 years; 91% Malay; 51% with an illness duration of more than 5 years). A between-group analysis showed that the awareness, knowledge and attitudes (AKA) about epilepsy did not significantly differ between the groups at baseline (P > 0.05). The intervention patients reported better AKA levels during follow-up compared to the control patients (P < 0.05). A within-group analysis showed that in intervention patients, there were significant improvements in all AKA domains with larger effect sizes (P < 0.01) while control patients also exhibited significant improvement in most domains except for Awareness but with smaller effect sizes. After controlling for possible confounding variables (age, gender, educational qualification, monthly income and baseline mean for each domain), the intervention group still reported significantly higher AKA than the control group particularly in Awareness (P < 0.001) and Total AKA (P = 0.003). There was also significantly better medication adherence and clinic attendance in the intervention group (P < 0.05). The results suggest that the addition of the MEES to conventional epilepsy education is effective in improving AKA.

This study reports the neurophysiological and behavioral correlates of digital memory encoding features in Chinese individuals with and without dyscalculia. Eighteen children with dyscalculia (ages 11.5-13.5) and 18 matched controls were tested, and their event-related potentials (ERPs) were digitally recorded simultaneously with behavioral measures. The results showed that both groups had a significant Dm effect, and this effect was greater in the control group. In the 300-400-ms, 400-500-ms, and 600-700-ms processing stages, both groups showed significant differences of digital memory encoding in the frontal, central, and parietal regions. In the 500-600-ms period, the Dm effect in the control group was significantly greater than that in the dyscalculia group only in the parietal region. These results suggest that individuals with dyscalculia exhibit impaired digital memory encoding and deficits in psychological resource allocation. Copyright © 2014 Elsevier Ltd.

This quasi-experimental study examined the effects of cognitive-behavioral therapy (CBT) to control depression, anger, and self-control in soldiers from South Korea. Using a pretest-posttest design, the sample was composed of an experimental group (n = 16) and a control group (n = 12). The experimental group participated in four sessions of CBT. No significant differences were found between the groups with regard to demographic characteristics. Changes in the variables after the intervention were analyzed using Wilcoxon's signed-rank sum test. The depression scores decreased significantly after the intervention (z = -3.05, p = 0.002); whereas, the scores of state-trait anger and self-control did not change. In the control group, none of the outcome variable scores changed significantly. The results indicate that the developed CBT program might be an effective modality to decrease the depression of soldiers who are in military service. Copyright 2014, SLACK Incorporated.

The model of myocardial ischemia-reperfusion injury was duplicated by ligating the left anterior descending coronary artery (LADCA) in the later four groups, and the LADCA was not ligated in the sham-operation group. The rats in the treatment groups were treated with electroacupuncture at "Jiaji" (EX-B 2), "Neiguan" (PC 6) and "Yanglingquan" (GB 34) on both sides, respectively, once a day for 7 days. No interventions were produced in the sham-operation group and model group. Myocardial apoptosis were examined by the TUNEL method. The expressions of Bcl-2 and Bax proteins were measured by immunohistochemical method. Apoptosis index(AI) was significantly lower in the Jiaji group, Neiguan group and sham-operation group compared with model group (P < 0.01). Compared with the sham-operation group, AI were significantly increased in other groups (all P < 0.01). There was no significant difference in AI between Jiaji and Neiguan group (P > 0.05). Compared with the model group, the expression of Bcl-2 was significantly increased and Bax protein was significantly decreased in Jiaji group and Neiguan group (both P < 0.01). The expressions of Bcl-2 and Bax proteins were significantly increased in other groups compared with the sham-operation group (all P < 0.01). There was no significant difference in the expression of Bcl-2 and Bax proteins between Jiaji and Neiguan group (P > 0.05). Electroacupuncture at both Jiaji (EX-B 2) and Neiguan (PC 6) has protective effects on myocardial ischemia-reperfusion injury, and the mechanism is closely related to inhibiting myocardial apoptosis by adjusting the expression of Bcl-2 and Bax.

Epidural scar formation after laminectomy impede surgical outcomes of decompression. Mitomycin C (MMC) has been demonstrated to have significant inhibitory effects on epidural scar. This study was undertaken to develop an effective MMC controlled‑release membrane and to investigate its effects on epidural scar in rat models of laminectomy. A total of 72 rats that underwent laminectomy were divided into three groups. Among them, 24 were treated with mitomycin C‑polylactic acid (MMC-PLA) controlled‑release membrane, 24 with mitomycin C-polyethylene glycol (MMC-PEG) controlled-release membrane, and no treatment was performed for the remaining 24 rats (control group). In the following 4 weeks, magnetic resonance image (MRI), macroscopic observation, histology and hydroxyproline (Hyp) concentration analysis were performed to explore the effects of these three therapies on epidural scar. MRI revealed a significant reduction of epidural fibrosis in MMC-PLA and MMC-PEG treatment groups, compared with the control group. Histological results also showed that collagen deposition was significantly reduced after being treated with MMC-PLA or MMC-PEG membranes. Likewise, Hyp concentrations of the epidural scar tissue in MMC-PLA and MMC-PEG groups were markedly lower than those in the control group. However, regarding the effects on reducing epidural scar, no significant difference was found between the MMC-PLA and MMC-PEG groups. In conclusion, MMC-PLA and MMC-PEG membranes are safe and effective in reducing fibrosis. Thus, MMC-controlled-release membranes promises to be a potential therapeutic in preventing epidural scar formation after laminectomy.

At present, commercially available antiurolithic drugs have more adverse effects than potential therapeutic or preventive effects with chronic use. With this in mind, the present study was designed to assess the antiurolithic effect of olive oil in a mouse model of ethylene glycol (EG)-induced urolithiasis. Adult albino mice were divided into 6 groups. Group I was fed the vehicle only. Group II was supplemented with 0.75% EG alone in drinking water during the experimental period to initiate deposition of calcium oxalate in kidneys, which leads to urolithiasis in animals. Groups III (olive oil control group) through V were fed olive oil orally at various doses during the experimental period. Group VI received cystone (750 mg/kg). Groups IV-VI additionally received 0.75% EG in drinking water ad libitum. SPSS ver.17.0 was used for statistical analysis. The study results showed significantly higher levels of serum urea, uric acid, and creatinine (p<0.05) in group II than in groups III-VI and I. Administration of olive oil at different doses restored the elevated serum parameters in groups IV and V compared with group II. Urine and kidney calcium, oxalate, and phosphate levels in groups IV-VI were significantly lower (p<0.05) than in animals with EG-induced urolithiasis (group II). Group V mice showed a significant restoration effect on serum as well as urine and kidney parameters compared with group II. Supplementation with olive oil (1.7 mL/kg body weight) reduced and prevented the growth of urinary stones, possibly by inhibiting renal tubular membrane damage due to peroxidative stress induced by hyperoxaluria.

In order to study the effect of electromagnetic fields (0.3 mT, 50 Hz) on some biomechanical and biochemical properties of rats’ blood, healthy thirty male albino rats of 150 ± 10 g were divided into three equal groups namely A, B1, B2. Group A used as a control group, group B1 was continuously exposed to a magnetic field of (0.3 mT, 50 Hz) for a period of 21 days for direct effect studies. Group B2 was continuously exposed to the same magnetic field for the same period of time, then was housed away from the magnetic field for a period of 45 days for delayed effects studies. After examination, the results indicated that the apparent viscosity and the consistency index increased significantly and very high significantly for groub B1 and B2 compared to control at P<0.05. Red blood cell counts (RBCs) membrane elasticity had significantly and very high significantly decreased for groups B1 and B2. Moreover, delayed effects studies indicated that there is deterioration in the bone marrow functions. These results are supported by the blood film image, where irregularities and deformations in the RBCs membranes had been occurred. We conclude that the cell membrane properties are highly affected by the extremely low frequency (ELF) magnetic fields, which proved to be biologically toxic.

Many daily activities, such as tying one’s shoe laces, opening a jar of jam or performing a free throw in basketball, require the skillful coordinated use of both hands. Even though the non-invasive method of transcranial direct current stimulation (tDCS) has been repeatedly shown to improve unimanual motor performance, little is known about its effects on bimanual motor performance. More knowledge about how tDCS may improve bimanual behavior would be relevant to motor recovery, e.g., in persons with bilateral impairment of hand function. We therefore examined the impact of high-definition anodal tDCS (HD-atDCS) on the performance of a bimanual sequential sensorimotor task. Thirty-two volunteers (age M = 24.25; SD = 2.75; 14 females) participated in this double-blind study and performed sport stacking in six experimental sessions. In sport stacking, 12 specially designed cups must be stacked (stacked up) and dismantled (stacked down) in predefined patterns as fast as possible. During a pretest, posttest and follow-up test, two sport stacking formations (3-6-3 stack and 1-10-1 stack) were performed. Between the pretest and posttest, all participants were trained in sport stacking with concurrent brain stimulation for three consecutive days. The experimental group (STIM-M1) received HD-atDCS over both primary motor cortices (M1), while the control group received a sham stimulation (SHAM). Three-way analysis of variance (ANOVA) revealed a significant main effect of TIME and a significant interaction of TIME × GROUP. No significant effects were found for GROUP, nor for the three-way interaction of TIME × GROUP × FORMATION. Further two-way ANOVAs showed a significant main effect of TIME and a non-significant main effect for GROUP in both sport stacking formations. A significant interaction between TIME × GROUP was found only for the 3-6-3 formation, indicating superior performance gains for the experimental group (STIM-M1). To account and control for baseline influences on the outcome measurements, ANCOVAs treating pretest scores as covariates revealed a significant effect of the stimulation. From this, we conclude that bilateral HD-atDCS over both M1 improves motor performance in a bimanual sequential sensorimotor task. These results may indicate a beneficial use of tDCS for learning and recovery of bimanual motor skills. PMID:28747875

Statins represent a group of drugs that are currently indicated in the primary and secondary prevention of cardiovascular events. Their administration can be associated with side effects and the insufficient reduction of triacylglyceride (TAG) levels. This study aimed to assess the effect of the triple combination of statins with omega-3 fatty acids and coenzyme Q10 (CoQ10) on parameters associated with atherogenesis and statin side effects. In this pilot randomized double-blind trial, 105 subjects who met the criteria of combined dislipidemia and elevated TAG levels were randomly divided into three groups. In the control group, unaltered statin therapy was indicated. In the second and third groups, omega-3 PUFA 2.52 g/day (Zennix fa Pleuran) and omega-3 PUFA 2.52 g+CoQ10 200 mg/day (Pharma Nord ApS) were added, res//. At the end of the 3-month period (±1 week), all patients were evaluated. Significant reduction of hepatic enzymes activity, systolic blood preasure, inflammatory markers and TAG levels were detected in both groups in comparison to the control group. Activity of SOD and GPx increased significantly after additive therapy. Coenzyme Q10 addition significantly reduced most of the abovementioned parameters (systolic blood preasure, total cholesterol, LDL, hsCRP, IL-6, SOD) in comparison with the statin+omega-3 PUFA group. The intensity of statin adverse effects were significantly reduced in the group with the addition of CoQ10. The results of this pilot study suggest the possible beneficial effects of triple combination on the lipid and non-lipid parameters related to atherogenesis and side effects of statin treatment.

Background: Acne vulgaris is a chronic inflammatory disease of the pilosebaceous follicles and one of the most common skin diseases. The peeling method has been recently found to be effective for acne treatment. This study aimed to compare the efficacy of pyruvic acid 50% and salicylic acid 30% peeling in the treatment of mild to moderate acne. Materials and Methods: In a prospective single-blinded clinical trial, 86 patients with acne were randomly assigned into two groups. In both groups, the routine treatment of acne (topical solution of erythromycin 4%, triclorocarban soap, and sunscreen) were used twice a day for 8 weeks. In addition, salicylic acid 30% for the control group and pyruvic acid 50% for the case group were used. In both groups, acne severity index (ASI) was calculated before and at week 2, 4, 6, and 8 of the treatment. Patient satisfaction was assessed at the end of the treatment. Side effects were recorded using a checklist. Results: In both groups, the reduction in the number of comedones, papules, and ASI were statistically significant (P < 0.001) in the course of treatment. However, it was not significant regarding the number of pustules (P = 0.09). None of the number of comedone, papules, pustules, and ASI was statistically different between study groups. Both treatment groups had similar side effects except for scaling in the fifth session, which was significantly lower in salicylic acid – treated patients (P = 0.015). Conclusion: Both pyruvic acid 50% and salicylic acid 30% are effective in the improvement of mild to moderate acne with no significant difference in efficacy and side effects. PMID:27904577

Cognitive Rehabilitation for Alzheimer's disease (AD) is an integrative multimodal intervention. It aims to maintain autonomy and quality of life by enhancing the patients' abilities to compensate for decreased cognitive functioning. We evaluated the feasibility of a group-based Cognitive Rehabilitation approach in mild AD dementia and assessed its effect on activities of daily living (ADL). We included 16 patients with AD dementia in a controlled partial-randomized design. We adapted the manual-guided Cognitive Rehabilitation program (CORDIAL) to a group setting. Over the course of three months, one group received the Cognitive Rehabilitation intervention (n = 8), while the other group received a standardized Cognitive Training as an active control condition (n = 8). ADL-competence was measured as primary outcome. The secondary outcome parameters included cognitive abilities related to daily living, functional cognitive state, and non-cognitive domains, e.g., quality of life. For each scale, we assessed the interaction effect 'intervention by time', i.e., from pre-to post-intervention. We found no significant interaction effect of intervention by time on the primary outcome ADL-competence. The interaction effect was significant for quality of life (Cohen's d: -1.43), showing an increase in the intervention group compared with the control group. Our study demonstrates the feasibility of a group-based Cognitive Rehabilitation program for patients with mild AD dementia. The Cognitive Rehabilitation showed no significant effect on ADL, possibly reflecting a lack of transfer between the therapy setting and real life. However, the group setting enhanced communication skills and coping mechanisms. Effects on ADL may not have reached statistical significance due to a limited sample size. Furthermore, future studies might use an extended duration of the intervention and integrate caregivers to a greater extent to increase transfer to activities of daily living.

To investigate the clinical effect of hemoperfusion combined with hemodialysis in the treatment of severe organophosphate pesticide poisoning. Ninety-eight patients with severe organophosphate pesticide poisoning who were admitted to the emergency department of our hospital from March 2005 to September 2013 were equally divided into control group and observation group according to treatment methods. The control group was given conventional emergency treatment, while the observation group was given hemoperfusion combined with hemodialysis and the conventional emergency treatment. The clinical outcomes and complications of two groups were compared. In the control group, 35 patients were cured and 14 patients died, so the cure rate was 71.4%. In the treatment group, 46 patients were cured and 3 patients died, so the cure rate was 93.9%. The treatment group had a significantly higher cure rate than the control group (χ² = 8.611, P < 0.05). And the treatment group had significantly shorter duration of coma (P < 0.01), mean length of hospital stay (P < 0.01), and time to recovery of cholinesterase activity (P < 0.01) and a significantly reduced dose of atropine than the control group (P < 0.01). The control group had significantly more cases of urinary retention than the treatment group (18 vs. 6, χ² = 4.991, P < 0.05). And the control group had more cases of intermediate syndrome, respiratory failure, delayed neurological damage, and rebound than the treatment group. Hemoperfusion combined hemodialysis has a good clinical effect and causes fewer complications in treating severe organophosphate pesticide poisoning, so it is worthy of clinical promotion.

To assess the effect of perioperative administration of a selective cyclooxygenase 2 inhibitor (celecoxib) on pain management and recovery of function after total knee arthroplasty (TKA). Randomized, controlled trial conducted from January 2005 through February 2006, 60 patients underwent TKA for osteoarthritis or rheumatoid arthritis were randomly divided into group of perioperative, administration of celecoxib (Study group, n = 30) and postoperative administration of celecoxib (Control group, n = 30). Patients in Study group were given oral celecoxib 3 d before TKA, 200 mg twice daily, and extended to 5 d postoperatively; patients in Control group were given oral celecoxib 2 h after TKA, 200 mg twice daily, and extended to 5 d postoperatively. All operations were finished by the same surgeon group. The postoperative patient-controlled analgesia (PCA) consumption was significantly less in Study group than in Control group [(43 +/- 12) ml vs. (53 +/- 12) ml, P < 0.05]. The pain scores of postoperative 4, 8, 12 h, 1, 2 d in Study group were 6.1 +/- 1.2, 5.0 +/- 1.3, 4.3 +/- 1.1, 3.4 +/- 1.2, significantly less than in Control group (P < 0.05); There were no intergroup significant differences in the pain scores of postoperative 3, 4, 5 d (P > 0.05). There were no intergroup significant differences in respect to the side-effect occurrence, operation time and postoperative drainage, postoperative analgesic consumption (P > 0.05). The time to achieve 90 degrees knee flexion was significantly shorter in Study group than in Control group [(6.2 +/- 1.7) d vs. (8.6 +/- 1.8) d, P < 0.05]. Perioperative administration of the selective Celecoxib holds the effect of preemptive analgesia. Compared with postoperative administration, perioperative administration of celecoxib can alleviate the early postoperative pain score, reduce the consumption of postoperative analgesic, accelerate the recovery of joint motion and thus increase the patient satisfaction.

In contrast to psychological interventions the usefulness of acupuncture as an adjuvant therapy in rheumatoid arthritis (RA) has not yet been demonstrated. The efficacy of auricular electroacupuncture (EA) was directly compared with autogenic training (AT). Patients with RA (n = 44) were randomized into EA or AT groups. EA and lessons in AT were performed once weekly for 6 weeks. Primary outcome measures were the mean weekly pain intensity and the disease activity score 28 (DAS 28); secondary outcome measures were the use of pain medication, the pain disability index (PDI), the clinical global impression (CGI) and pro-inflammatory cytokine levels, which were assessed during the study period and 3 months after the end of treatment. At the end of the treatment and at 3-month follow-up a clinically meaningful and statistically significant improvement (p < 0.05) could be observed in all outcome parameters and both groups. In contrast to the AT group, the onset of these effects in the EA group could already be observed after the 2nd treatment week. In the 4th treatment week the EA group reported significantly less pain than the AT group (p = 0.040). After the end of treatment (7th week) the EA group assessed their outcome as significantly more improved than the AT group (p = 0.035). The erythrocyte sedimentation rate in the EA group was significantly reduced (p = 0.010), and the serum concentration of tumor necrosis factor-alpha was significantly increased compared to the AT group (p = 0.020). The adjuvant use of both EA and AT in the treatment of RA resulted in significant short- and long-term treatment effects. The treatment effects of auricular EA were more pronounced.

Increasing proportion of the elderly in the driving population raises the importance of assuring their safety. We explored the effects of three different types of cognitive training on the cognitive function, brain structure, and driving safety of the elderly. Thirty-seven healthy elderly daily drivers were randomly assigned to one of three training groups: Group V trained in a vehicle with a newly developed onboard cognitive training program, Group P trained with a similar program but on a personal computer, and Group C trained to solve a crossword puzzle. Before and after the 8-week training period, they underwent neuropsychological tests, structural brain magnetic resonance imaging, and driving safety tests. For cognitive function, only Group V showed significant improvements in processing speed and working memory. For driving safety, Group V showed significant improvements both in the driving aptitude test and in the on-road evaluations. Group P showed no significant improvements in either test, and Group C showed significant improvements in the driving aptitude but not in the on-road evaluations. The results support the effectiveness of the onboard training program in enhancing the elderly's abilities to drive safely and the potential advantages of a multimodal training approach.

Reversal of left ventricular hypertrophy (LVH) in hypertensive patients appears to be a desirable goal to the reduction cardiac risk. The Renin-Angiotensin System (RAS) seems to play a major role in the establishment and maintenance of LVH through the activated systemic RAS and the Intracardiac Angiotensin System (IAS). We focused on the effects of a three-year treatment with losartan supplement in hypertensive patients with LVH not responding to eight years of an effective previous antihypertensive pharmacological treatment. Two groups of 28 sex-, age- and therapy-matched subjects with essential hypertension and LVH were taken into consideration. The two groups were in effective pharmacological treatment (BP < 140/90) for eight years previous to their enrollment. Patients of Group A were treated for three years with a losartan (100 mg/die) on-top treatment, whereas patients of Group B continued the follow-up of the previous conventional therapy. Both groups were submitted to an echocardiographic follow-up. Group A, showed a significant reduction of the mean LVH since the first step at six months with a further significant trend during the whole period (variance analysis: p < 0.001). Group B showed a non-significant trend toward LVH reduction during the three-year follow-up. No significant further reduction of systolic or diastolic blood pressure values was observed in both groups. The effects of losartan in hypertensive and hypertrophic patients are in agreement with the results of LIFE Trial. However, the reduction of left ventricular hypertrophy in our patients seems to be related to changes inducted by losartan on the IAS, since no further hemodynamic effects were observed. Losartan induced both a significant reduction of LVH and an improvement of LV diastolic function with a subsequent expected beneficial shift on the prognosis.

This study aimed (1) to geometrically evaluate areas of facial asymmetry in patients with two different types of maxillectomy defect compared to a control group, (2) to geometrically evaluate the effect of an obturator prosthesis on facial asymmetry, and (3) to investigate the correlation between three-dimensional (3D) deviation values and number of missing teeth. Facial data from 13 normal control participants and 26 participants with two types of maxillectomy defect (groups 1 and 2) were acquired with a noncontact 3D digitizer. Facial asymmetry was evaluated by superimposing a facial scan onto its mirror scan using 3D evaluation software. Facial scans with and without obturator prostheses were also superimposed to evaluate the obturator effect. The correlation between 3D deviation values and number of missing teeth was also evaluated. Statistical analyses were performed. Facial asymmetry was significantly different between the control group and each maxillectomy defect group (group 1: P < .0001 and P = .020 without and with obturator, respectively; group 2: P < .0001 for both conditions). There were no significant differences in asymmetry between groups 1 and 2 either without or with obturator (P = .457 and P = .980, respectively). There was a significant difference in the obturator effect between groups 1 and 2 (P = .038). 3D deviation values were positively correlated with number of missing teeth in group 1 (r = 0.594, P = .032), but not in group 2. A noncontact 3D digitizer and 3D deviation assessment were effective for analyzing facial data of maxillectomy patients. Obturators were effective for improving facial deformities in these patients.

The purpose of this study was to identify the effectiveness of low and high volume plyometric loads on developing stretch shortening cycle capability in collegiate rugby players. A between- group repeated measures design was used. Thirty six subjects (age 20.3 ±1.6 yrs, mass 91.63 ±10.36kg, stature 182.03 ±5.24cm) were randomly assigned to one of three groups, a control group (CG), a low volume plyometric group (LPG) or a high volume plyometric group (HPG). Data were collected from a force plate, and measures of reactive strength index (RSI) and leg stiffness were calculated from jump height, contact time and flight time. A significant between group × time (F = 4.01, P <0.05) interaction effect for RSI was observed. Bonferroni post hoc analysis indicated that both the LPG training group (P = 0.002) and HPG training group (P = 0.009) were significantly higher than the control group. No significant interaction effect between time × group were observed for leg stiffness (F = 1.39, P = 0.25). The current study has demonstrated that it is possible to improve reactive strength capabilities via the use of a low volume plyometric program. The low volume program elicited the same performance improvement in RSI as a high volume program whilst undertaking a lower dose. This suggests that strength and conditioning coaches may be able to benefit from the ability to develop more time efficient and effective plyometric programs.

Live yeast (Saccharomyces cerevisiae) constitutes an effective additive for animal production; its probiotic effect may be related to the concentrate-to-forage ratio (CTFR). The objective of this study was to assess the effects of S. cerevisiae (SC) on fiber degradation and rumen microbial populations in steers fed diets with different levels of dietary concentrate. Ten Simmental × Local crossbred steers (450 ± 50 kg BW) were assigned to a control group or an SC group. Both groups were fed the same basal diet but the SC group received SC supplementation (8 × 10(9) cfu/h/d through the ruminal fistula) following a two-period crossover design. Each period consisted of four phases, each of which lasted 17 d: 10 d for dietary adaptation, 6 d for degradation study, and 1 d for rumen sample collection. From the 1(st) to the 4(th) phase, steers were fed in a stepwise fashion with increasing CTFRs, i.e., 30:70, 50:50, 70:30, and 90:10. The kinetics of dry matter and fiber degradation of alfalfa pellets were evaluated; the rumen microbial populations were detected using real-time PCR. The results revealed no significant (P > 0.05) interactions between dietary CTFR and SC for most parameters. Dietary CTFR had a significant effect (P < 0.01) on degradation characteristics of alfalfa pellets and the copies of rumen microorganism; the increasing concentrate level resulted in linear, quadratic or cubic variation trend for these parameters. SC supplementation significantly (P < 0.05) affected dry matter (DM) and neutral detergent fiber (NDF) degradation rates (c DM, c NDF) and NDF effective degradability (EDNDF). Compared with the control group, there was an increasing trend of rumen fungi and protozoa in SC group (P < 0.1); copies of total bacteria in SC group were significantly higher (P < 0.05). Additionally, percentage of Ruminobacter amylophilus was significantly lower (P < 0.05) but percentage of Selenomonas ruminantium was significantly higher (P < 0.05) in the SC group. In a word, dietary CTFR had a significant effect on degradation characteristics of forage and rumen microbial population. S. cerevisiae had positive effects on DM and NDF degradation rate or effective degradability of forage; S. cerevisiae increased rumen total bacteria, fungi, protozoa, and lactate-utilizing bacteria but reduced starch-degrading and lactate-producing bacteria.

Previous published results have revealed that Rhinolight ® intranasal phototherapy is safe and effective in intermittent allergic rhinitis. The present objective was to assess whether phototherapy is also safe and effective in persistent allergic rhinitis. Thirty-four patients with persistent allergic rhinitis were randomized into two groups; twenty-five subjects completed the study. The Rhinolight ® group was treated with a combination of UV-B, UV-A, and high-intensity visible light, while the placebo group received low-intensity visible white light intranasal phototherapy on a total of 13 occasions in 6 weeks. The assessment was based on the diary of symptoms, nasal inspiratory peak flow, quantitative smell threshold, mucociliary transport function, and ICAM-1 expression of the epithelial cells. All nasal symptom scores and nasal inspiratory peak flow measurements improved significantly in the Rhinolight ® group relative to the placebo group and this finding persisted after 4 weeks of follow-up. The smell and mucociliary functions did not change significantly in either group. The number of ICAM-1 positive cells decreased non-significantly in the Rhinolight ® group. No severe side-effects were reported during the treatment period. These results suggest that Rhinolight ® treatment is safe and effective in persistent allergic rhinitis.

Coffee has been inversely related to the incidence of human liver disease; however, whether caffeine is the component responsible for the beneficial effects of coffee remains controversial. This study evaluated the beneficial effects of coffee or caffeine in a medium-term bioassay for rat liver fibrosis/carcinogenesis induced by diethylnitrosamine (DEN) and carbon tetrachloride (CCl4). One week after the DEN injection, the groups started to receive conventional coffee, instant coffee or 0.1% caffeine ad libitum for 24 weeks. The groups receiving conventional coffee or caffeine presented a significant reduction in collagen content and mRNA expression of collagen I. The groups receiving instant coffee or caffeine had a significant reduction in the size and area of pre-neoplastic lesions and in the mean number of neoplastic lesions. A significant increase in liver bax protein levels was observed in the groups receiving instant coffee or caffeine as compared to the control group. These data indicate that the most pronounced hepatoprotective effect against fibrosis was observed in the groups receiving conventional coffee and 0.1% caffeine, and the greatest effects against liver carcinogenesis were detected in the groups receiving instant coffee and 0.1% caffeine.

Laser irradiation has been suggested as an adjunct to traditional caries prevention methods. But little is known about the cariostatic effect of diode laser and most studies available are on permanent teeth.The purpose of the present study was to investigate the effect of diode laser irradiation combined with topical fluoride on enamel surface microhardness. Forty-five primary teeth were used in this in vitro study. The teeth were sectioned to produce 90 slabs. The baseline Vickers microhardness number of each enamel surface was determined. The samples were randomly divided into 3 groups. Group 1: 5% NaF varnish, group 2: NaF varnish+ diode laser at 5 W power and group 3: NaF varnish+ diode laser at 7 W power. Then, the final microhardness number of each surface was again determined. The data were statistically analyzed by repeated measures ANOVA at 0.05 level of significance. In all 3 groups, microhardness number increased significantly after surface treatment (P<0.05). However, Microhardness change after treatment was not significantly different among groups (P >0.05). The combined application of diode laser and topical fluoride varnish on enamel surface did not show any significant additional effect on enamel resistance to caries.

To observe the effect of MK-801 and taurine on the activities of GS and PAG and the glutamatic neuron content in the rat striatum exposed by manganese. 40 Wistar rats were random divided into four groups. The first group was the control group which was subcutaneously injected at the content of 0.9% NaCl. The second group was MnCl2 group which was subcutaneously injected at the content of 0.9% NaCl. The third and fourth groups were pretreatment groups which were subcutaneously injected of 0.3 micromol/kg MK-801 and 1 mmol/kg taurine. After 2h, the first group was peritoneally injected at the content of 0.9% NaCl, the 2nd-4th group were peritoneally injected at the dose of 200 micromol/kg MnCl2. All administration was given at the dose of 5 ml/kg for 25d, the pretreatment groups were given for every other day. At the 24h after the administration of MnCl2, the 4 rats brain tissue in every groups were removed after the rats were perfused from the left ventricles to with 4% ploymerisatum. The glutamatic neuron content were determined by immunohistochemical method (SABC). The activities of GS and PAG in the residual rat striatum were determined. In comparison with control group, the percentage of positive area and integral optical densities of glutamate immunocreative cell increased significantly in MnCl2 group (P < 0.01), the activity of GS decreased significantly in MnCl2 group, the activity of PAG increased significantly in MnCl2 group. In comparison with MnCl2 group, the percentage of positive area and integral optical density of glutamate immunocreative cell decreased significantly in MK-801 and taurine pretreatment group, the activity of GS increased significantly in MK-801 and taurine pretreatment group , the activity of PAG decreased significantly in MK-801 pretreatment group. MK-801 and taurine have a certain protective effect on "the circuitry of glutamate and glutamine" disrupted with Mn.

The objectives of the study were to assess evaluate the effects of aluminum chloride (AlCl 3 ) on blood glucose and lipid levels in normal, diabetic, and glibenclamide-treated diabetic rats. Forty-two male Wistar rats were divided into seven groups of six each. Group I was normal control, Groups II and III were given AlCl 3 50 and 100 mg/kg, and Group IV to VII were administered with streptozotocin (STZ) (60 mg/kg) intraperitoneally. Group IV was diabetic control, Group V in addition was given AlCl 3 50 mg/kg, Group VI glibenclamide (10 mg/kg), and Group VII glibenclamide and AlCl 3 (50 mg/kg) per-oral daily for 28 days. Blood glucose and lipid levels were estimated at base line, after diabetes was set in and on the last day of study. Histopathological changes in pancreas, liver, and kidney were studied. No significant change was observed in blood glucose and lipid levels in Group I. Group II and III showed a dose-dependent significant increase in blood glucose was observed. Group V had a reduction in blood glucose but not to the nondiabetic level. Group VI had significant reduction in blood sugar. In Group VII, treated with glibenclamide and AlCl 3 , there was no significant change in blood glucose reduction compared to Group VI. Lipid levels were reduced in groups treated with AlCl 3 and glibenclamide and not in other groups. Gross tissue damage was seen in pancreas in STZ group and in liver and kidney in AlCl 3 groups. AlCl 3 administration in Wistar rats caused in significant hyperglycemia in normal rats, hypoglycemia in diabetic rats, and did not influenced hypoglycemic effect of glibenclamide and in addition, resulted in reduction in lipid levels.

The present study was done to evaluate the effect of boldenone undecylenate (BOL) on growth performance, maintenance behaviour, reproductive hormones and carcass traits of male rabbits. Sixty apparently healthy New Zealand White male rabbits, 5 weeks of age, were allotted to 3 equal groups. Each group was subdivided into 5 replicates, where the first group is control. The second group (B1) comprised rabbits that received 2 intramuscular injections of BOL (5 mg/kg) with 3 week intervals (9 and 12 weeks of age), while the third group (B2) included rabbits that received 3 intramuscular injections of BOL (5 mg/kg) with 2 week intervals (8, 10 and 12 weeks of age). The end of the trial was after 4 weeks from the last injection (16 weeks of age). The results revealed that the treated groups had a significant increase in total body weight, daily gain and feed efficiency, with a significant decrease in feed conversion ratio (FCR). Ingestive, locomotion and grooming behaviors were significantly higher in treated groups. Lateral pasture and exploratory behaviors were significantly higher in the control group. Administration of BOL resulted in a significant increase in dressing % and a significant decrease in testes %. Groups treated with BOL had a significantly (P<0.05) decreased serum testosterone level, simultaneously with a significantly increased estradiol level. The results indicate that BOL improves performance and carcass traits. Furthermore, there are hormonal-behavioral correlations through enhancement of ingestive and locomotion behaviors of treated animals.

BACKGROUND This study aimed to explore the therapeutic effect of external application of ligustrazine combined with holistic nursing on pressure sores, as well as the underlying mechanism. MATERIAL AND METHODS From February 2014 to March 2015, a total of 32 patients with Phase II and Phase III pressure sores were enrolled and randomly assigned to an experimental group or a control group. The clinical data were comparable between the 2 groups. In addition to holistic nursing, the patients in the experimental group received 4 weeks of continuous external application of ligustrazine, whereas patients in the control group received compound clotrimazole cream. Therapeutic effect and healing time were recorded. HaCaT cells were used as an in vitro model for mechanism analysis of the effect of ligustrazine in treating pressure sores. After culturing with different concentrations of ligustrazine or the inhibitor of AKT (LY294002) for 72 h, cell viability, clone formation numbers, and levels of phosphatidyl inositol 3-kinase (PI3K), p-AKT, and p-mammalian target of rapamycin (mTOR) were determined. RESULTS Compared to the control group, the total effective rate in the experimental group was significantly higher, and the healing time was significantly reduced. Cell viability and clone formation numbers were significantly upregulated by ligustrazine in a dose-dependent manner. Both the cell viability and clone formation numbers were significantly inhibited by application of LY294002. CONCLUSIONS Our results suggest that ligustrazine combined with holistic nursing is an effective treatment of pressure sores. The protective effect may be associated with the promotion of cell growth by activation of the PI3K/AKT pathway.

Recent literature suggests that Ca supplements have adverse effects on cardiovascular health. The effects of a Ca-rich supplement administered alone or in combination with short-chain fructo-oligosaccharides (scFOS) on serum lipids in postmenopausal women were examined using secondary data from a 24-month double-blind randomised controlled study. A total of 300 postmenopausal women were randomly assigned to daily supplements of 800 mg of Ca (2·4 g Aquamin) (Ca), 800 mg of Ca with 3 g of scFOS (CaFOS) or control (maltodextrin) (MD). A full lipid profile, body composition, blood pressure and a range of cytokines were measured at baseline and after 24 months. Intention-to-treat ANCOVA assessed treatment effects between the groups. A significant time-by-treatment effect was observed for LDL and total cholesterol for the Ca and CaFOS groups, with both groups having lower LDL and total cholesterol concentrations compared with MD after 24 months. The control group had mean (5·2 mmol/l) total cholesterol concentrations above the normal range (≤ 5 mmol/l) at 24 months, whereas values remained within the normal range in the treatment groups. There was no significant treatment effect on HDL-cholesterol, TAG, body composition, blood pressure or cytokine concentrations at 24 months, with the exception of IL-4, where there was a significant increase in the CaFOS group compared with the placebo. This study demonstrates a lipid-lowering effect of both the Ca-rich supplement alone and the supplement with scFOS. At the 4-year follow-up, there was no significant difference between the groups for reported diagnosed cardiovascular conditions.

To compare the effectiveness, adverse effects, and cost-effectiveness of percutaneous neurolytic celiac plexus block (NCPB) versus traditional medication strategies for the treatment of patients with advanced cancer having severe upper abdominal cancer pain. This retrospective study included 81 patients with advanced upper abdominal cancer admitted to The Sixth People's Hospital Affiliated to Shanghai Jiaotong University between January 2013 and July 2014. The patients were divided into percutaneous NCPB (treatment) and medication for pain (control) groups. The outcomes were measured in terms of Numeric Rating Scale (NRS) score and Karnofsky Performance Status (KPS) score before treatment and on the 3rd, 7th, 14th, and 28th days posttreatment. The effectiveness and cost-effectiveness of the therapy were assessed using analysis of the health economics. The improvements in NRS score (1.42 ± 1.09 vs 4.03 ± 0.96, P < .01) and KPS score (65.55 ± 9.09 vs 63.03 ± 8.961, P < .01) in the treatment group were significantly superior compared to the control group on the 7th day of treatment, followed by no significant difference between the 2 groups on the 14th and the 28th day of treatment. Health economics evaluation revealed that the medicine-specific costs and total health care costs were significantly reduced in the treatment group compared to the control group ( P < .05), but no significant differences between the 2 groups ( P > .05) were seen in the costs of hospitalization, examinations, and treatment. The percutaneous NCPB method shows promising results and better cost-effectiveness for treating patients with advanced cancer having severe upper abdominal pain.

The purpose of this trial was to determine whether cobedding of preterm twins has analgesic effects during heel lancing or not. One hundred premature twins (50 sets) born between 26 weeks' and 34 weeks' gestation undergoing heel blood sampling were randomly assigned into two groups: the cobedding group (receiving care in the same incubator) and the standard care group (receiving care in separate incubators). Pain was assessed using the premature infant pain profile score. Duration of crying was measured after heel blood sampling, and salivary cortisol was measured prior to and after heel blood sampling. Infants in the standard care group cried for a longer time during heel lancing than those in the cobedding group (42.6 ± 19.8 seconds vs. 36.4 ± 21.7 seconds, p = 0.03). The mean premature infant pain profile score after heel lancing was significantly higher in the standard care group (9.8 ± 2.6 vs. 8.06 ± 2.8, p = 0.002). The mean salivary cortisol after heel lancing was also significantly higher in the standard care group (24.3 ± 7.4 nmol/L vs. 20.8 ± 7.4 nmol/L, p = 0.02). No significant adverse effects were seen with cobedding. Cobedding is a comforting measure for twin premature infants during heel lancing, which can be performed without any significant adverse effects. Copyright © 2014. Published by Elsevier B.V.

Persicae Semen (Taoren) and Carthami Flos (Honghua) used in pair which is named as Taoren-Honghua (TH) herb pair has been used in traditional Chinese medicine (TCM) for promoting blood circulation to dissipate blood stasis for many years in China. This paper investigated the effects of TH and its main components amygdalin and hydroxysafflor yellow A (HSYA) on hemorheological disorders of blood stasis in rats. Rats were randomly divided into seven groups (control group, model group, TH group, amygdalin group, HSYA group, amygdalin+HSYA group, and aspirin group) with eight animals in each, whose gender was equally distributed throughout groups. All treatments were performed by gavage and administered seven times with an interval of 12h. After the fifth administration, the model rats except those in control group with blood stasis were established by being placed in ice-cold water during the interval between two injections of adrenaline hydrochloride (Adr); and blood samples were collected 30min after the last administration on the following day. TH could significantly decrease whole blood viscosity (WBV), plasma viscosity (PV) and packed cell volume (PCV). It also significantly prolonged thrombin time (TT) and thromboplastin time (APTT), increased prothrombin time (PT) and lowered fibrinogen content (FIB). HSYA which significantly decreased WBV and PV had no effect on plasma coagulation parameters. Amygdalin could significantly decrease PV, prolong APTT and decrease FIB, showing few effects on WBV. TH and its main components amygdalin and HSYA could significantly reduce platelet aggregation and protect vascular endothelial cells. Based on the above results, amygdalin and HSYA were responsible for the main curative effects of TH and usually had synergetic effects, such as decreasing PV and platelet aggregation percentage. The study may provide scientific information to further understanding of the mechanism(s) of TH and its main components in activating blood circulation to dissipate blood. It may also create valuable insight into the possible effects and utilization of TH and its components as a feasible alternative therapeutic agent for patients with hemorheological disorders.

To study the efficacy of short-term educational intervention for parents of preschool children with anxiety. Forty-nine children with Spence Preschool Anxiety Scale (SPAS) scores of ≥ 48 were randomly divided into intervention and control groups. The children's parents in the intervention group received a collective curriculum on children's anxiety management six times, while the control group was only followed up. All children were evaluated for anxiety by the SPAS 3 and 6 months later, and then the results were compared between the two groups. The test was completed in 21 cases of the intervention group and 22 cases of the control group. At month 3, the intervention group had a significantly lower percentage of children with SPAS scores of ≥ 48 than the control group (62% vs 91%; P<0.05), and this percentage was also significantly lower in the intervention group than in the control group at month 6 (52% vs 82%; P<0.05). At month 3, the intervention group had a significantly reduced mean SPAS score, which was significantly lower than that of the control group (69 ± 12 vs 81 ± 12; P<0.01). At month 6, both groups showed significant decreases in SPAS score, but still the SPAS score was significantly lower in the intervention group than in the control group (65 ± 13 vs 78 ± 13; P<0.01). Early short-term education for parents can relieve their preschool children's anxiety effectively, but the long-term effect needs to be evaluated by follow-up.

The purpose of this study was to investigate the effect of dietary taurine supplementation on bone mineral density (BMD) and bone mineral content (BMC) in rats. Twenty Sprague-Dawley male rats (body weight 200 ± 10 g) were divided into two groups, control and taurine group (2% taurine-supplemented diet). All rats were fed on experimental diet and deionized water and libitum for 6 weeks. Serum alkaline phosphatase (ALP) activity, osteocalcin, PTH, and urinary deoxypyridinoline cross-links value were measured as markers of bone formation and resorption. BMD and BMC were measured using PIXImus (GE Lunar Co., Wisconsin) in spine and femur. The effect of diet on ALP, osteocalcine, and PTH was not significant. There were no significant differences in ALP, osteocalcine, and PTH concentration. Urinary calcium excretion was lower in taurine group than in control group. Femur BMC/weight of taurine group was significantly higher than control group. The results of this study showed the possible role of taurine in bone metabolism in male rats.

Objective To determine whether spinal anesthesia combined with obturator nerve blockade (SOB) is effective in preventing obturator nerve stimulation, jerking and bladder perforation during transurethral resection of bladder tumor (TURBT). Material and methods In this clinical trial, 30 patients were randomly divided into two groups: spinal anesthesia (SA) and SOB. In SA group, 2.5 cc of 0.5% bupivacaine was injected intrathecally using a 25-gauge spinal needle and in SOB after spinal anesthesia, a classic obturator nerve blockade was performed by using nerve stimulation technique. Results There was a statistically significant difference between jerking in both groups (p=0.006). During the TURBT, surgeon satisfaction was significantly higher in SOB group compared to SA group (p=0.006). There was no significant correlation between sex, patient age and location of bladder tumor between the groups (p>0.05). Conclusion Obturator nerve blockade by using 15 cc lidocaine 1% is effective in preventing adductor muscle spasms during TURBT. PMID:29201516

[Purpose] This study aimed to investigate the effects of prone bridge exercise on trunk muscle thickness. [Subjects and Methods] Thirty-seven chronic low back pain patients participated in this study. Each participant was randomly assigned to one of three exercise groups, namely, a prone bridge exercise group, supine bridge exercise on a Swiss ball group, and supine bridge exercise group. The thicknesses of the transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) were measured using ultrasound. [Results] After eight weeks of training, the three groups showed significant increases in the thicknesses of the TrA, IO, and EO. Among the groups, TrA and IO showed significantly different muscle thicknesses. [Conclusion] The prone bridge exercise significantly affected the thicknesses of the TrA, IO, and EO unlike the supine bridge exercises. Based on the results of this study, the prone bridge exercise is a more effective method to improve trunk stability than conventional supine bridge exercises.

Acquisition of numerical knowledge and understanding of numerical information are crucial for coping with the changing demands of our digital society. In this study, we assessed arithmetic learning in older and younger individuals in a training experiment including brain imaging. In particular, we assessed age-related effects of training intensity, prior arithmetic competence, and neuropsychological variables on the acquisition of new arithmetic knowledge and on the transfer to new, unknown problems. Effects were assessed immediately after training and after 3 months. Behavioural results showed higher training effects for younger individuals than for older individuals and significantly better performance after 90 problem repetitions than after 30 repetitions in both age groups. A correlation analysis indicated that older adults with lower memory and executive functions at baseline could profit more from intensive training. Similarly, training effects in the younger group were higher for those individuals who had lower arithmetic competence and executive functions prior to intervention. In younger adults, successful transfer was associated with higher executive functions. Memory and set-shifting emerged as significant predictors of training effects in the older group. For the younger group, prior arithmetic competence was a significant predictor of training effects, while cognitive flexibility was a predictor of transfer effects. After training, a subgroup of participants underwent an MRI assessment. A voxel-based morphometry analysis showed a significant interaction between training effects and grey matter volume of the right middle temporal gyrus extending to the angular gyrus for the younger group relative to the older group. The reverse contrast (older group vs. younger group) did not yield any significant results. These results suggest that improvements in arithmetic competence are supported by temporo-parietal areas in the right hemisphere in younger participants, while learning in older people might be more widespread. Overall, our study indicates that arithmetic learning depends on the training intensity as well as on person-related factors including individual age, arithmetic competence before training, memory, and executive functions. In conclusion, we suggest that major progress can be also achieved by older participants, but that interventions have to take into account individual variables in order to provide maximal benefit.

We aimed to determine napping characteristics of community-dwelling patients with insomnia disorder (ID) compared to characteristics of normal controls (NC), and to examine the effect of napping on nocturnal sleep. Adult volunteers who were more than 18 years old were recruited from three rural public health centers in Korea. Data from actigraphy recording and a sleep diary filled out for seven days were obtained. Finally, 115 ID patients and 80 NC subjects were included in this study. Parameters and timing of nocturnal sleep and nap were compared between the ID and NC groups. Two-way analysis of covariance (ANCOVA) was performed to determine the effect of ID diagnosis and napping on sleep parameters. Sleep efficiency (SE) in the ID group was significantly lower (p = 0.010), and wake time after sleep onset (WASO) was significantly greater (p = 0.023), compared to the NC group. There was no significant difference in nocturnal sleep or nap timing between the two groups. Nap frequency in the ID group was significantly higher than that in the NC group (p = 0.025). Although ID diagnosis and napping had no independent effect on fragmentation index, their interaction had a significant effect on fragmentation index (p = 0.021). Nap frequency was positively correlated with PSQI score (r = 0.166, p = 0.033). Insomnia patients showed no significant difference in nap timing or nap duration compared to NC subjects. However, insomnia patients showed higher nap frequency. Frequent napping was associated with poorer subjective sleep quality. Therefore, although napping might not have a negative impact on nocturnal sleep maintenance in NC subjects, it did have an effect on nocturnal sleep in insomnia patients.

This study was conducted to evaluate the effects of a commercially available shampoo in Korean subjects with alopecia using a simple hand-held phototrichogram technique. Forty-four subjects with alopecia were enrolled and forty subjects continued for 16 weeks. In the test group, total hair counts increased significantly at weeks 8 and 16, and the number of shedding hair significantly decreased at week 16. Terminal hair counts significantly increased at week 8. In the control group, hair thickness and the number of vellus hairs significantly decreased at week 16. The number of total hairs significantly increased in the test group than in the control group at weeks 8 and 16. The number of shedding hairs significantly decreased in the test group than in the control group at week 16. Visual assessment using clinical digital images showed that the number of total hairs appeared to increase although there was no statistical significance. In this study, it was found that the test shampoo could prevent hair loss. © 2011 DERMAPRO Co Ltd. ICS © 2011 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

Pooling is an alternative method to achieve in vitro fertilization outcomes. This study was to investigate the effect of pooling method on pregnancy outcomes in poor responder patients according to Bologna criteria. Two hundred-fifty five poor responder patients were enrolled in this study. Pooling embryo transfer (ET) group had 110 and fresh ET group had 145 patients. Although, age was similar between both treatment groups (p=0.31), antral follicle count (p<0.001), total number of retrieved oocyte (p<0.001), total metaphase II oocyte count (p<0.001), number of stimulation cycles (p<0.001), were significantly different between the groups. The day of ET were similiar between two groups (p=0.72) but the number of ET procedure was significantly higher in pooling ET group compared to fresh ET (p<0.001). Positive pregnancy test [35/110 (32%) vs 53/145 (37%)] (p=0.43) and clinical pregnacy rates [31/110 (28%) vs 49/145 (34%)] (p=0.33) were similar between groups, whereas, implantation [31/191 (16%) vs 49/198 (25%)] (p=0.03) and live birth rates [15/110 (14%) vs 36/145 (25%)] (p=0.04) were significantly higher in fresh ET group. Despite that, abortion rates were significantly higher in pooling ET group [16/31 (52%) vs 13/49 (27%)] (p=0.04). Binary logistic regression analyese has revealed no effect of variables on live birth rates. Even though, pooling strategy seems to have a slight positive effect on pregnancy outcomes, there is no benefical effect on live birth rates. Furthermore, this strategy is increasing the abortion rates in parallel with clinical pregnancy rates.

Economic evaluation from a societal perspective conducted alongside a randomized controlled trial with a follow-up of 52 weeks. To evaluate the cost effectiveness and cost utility of an intensive group training protocol compared with usual care physiotherapy in patients with nonspecific chronic low back pain. The intensive group training protocol combines exercise therapy, back school, and behavioral principles. Two studies found a significant reduction in absenteeism for a graded activity program in occupational health care. This program has not yet been evaluated in a primary care physiotherapy setting. Participating physical therapists in primary care recruited 114 patients with chronic nonspecific low back pain. Eligible patients were randomized to either the protocol group or the guideline group. Outcome measures included functional status (Roland Morris Disability Questionnaire), pain intensity (11-point numerical rating scale), general perceived effect and quality of life (EuroQol-5D). Cost data were measured with cost diaries and included direct and indirect costs related to low back pain. After 52 weeks, the direct health care costs were significantly higher for patients in the protocol group, largely due to the costs of the intervention. The mean difference in total costs amounted to [Euro sign] 233 (95% confidence interval: [Euro sign] -2.185; [Euro sign] 2.764). The cost-effectiveness planes indicated no significant differences in cost effectiveness between the 2 groups. The results of this economic evaluation showed no difference in total costs between the protocol group and the guideline group. The differences in effects were small and not statistically significant. At present, national implementation of the protocol is not recommended.

Introduction The fruit of Psidium guajava (P.guajava) is known to contain free sugars yet the fruit juice showed hypoglycaemic effect. Hypoglycaemic activity of guava leaves has been well documented but not for guava fruit. Aim So we aimed to evaluate the effect of ripe guava (with peel and without peel) fruit supplementation on blood glucose and lipid profile in healthy human subjects. Materials and Methods Randomized Controlled study undertaken in: 1) Baseline; 2) 6 weeks supplementation phase. Forty five healthy MBBS students were included and randomly enrolled into Group A, Group B and Group C. In Baseline phase: Fasting Plasma Glucose (FPG) and serum lipid profile was done in all 3 groups. Group A were supplemented with 400g of ripe guava with peel and group B without peel, for 6 weeks. Rest 15 treated as control i.e., Group C. Result Supplementation of ripe guava fruit with peel reduced BMI as well as blood pressure (p<0.05) in group A, whereas the FPG, Total cholesterol, Triglycerides were found significantly increased (p<0.05). Group B registered a significant fall (p<0.05) in BMI as well as blood pressure. Fall in FPG level after guava pulp supplementation was not significant. Serum Total cholesterol, Triglycerides and Low Density Lipoprotein Cholesterol (LDLc) levels decreased significantly (p<0.05) indicating that guava pulp without peel may have a favourable effect on lipid levels and blood sugar as well. Conclusion Guava fruit without peel is more effective in lowering blood sugar as well as serum total cholesterol, triglycerides and LDLc. It increases HDLc levels also. PMID:27790420

Aim: To investigate the effects of training sessions on circulating β-endorphin changes in sport horses before and after competition and to ascertain whether competition would affect this response. Materials and Methods: A total of 24 trained jumping horses were randomly assigned to one of two training groups: Group A (competing) and Group B (not competing). To determined plasma β-endorphin concentrations, two pre- and post-competition training weeks at aerobic workout and two competitive show jumping event days at anaerobic workout were measured before, 5 and 30 min after exercise. Exercise intensity is described using lactate concentrations and heart rate. The circuit design, intensity, and duration of training sessions were the same for both groups. Results: In Group A, one-way analysis of variance for repeated measures (RM-ANOVA) showed significant effects of exercise on β-endorphin changes (F=14.41; p<0.001), only in the post-competition training sessions, while in Group B showed no significant effects. Two-way RM-ANOVA showed, after post-competition training sessions, a significant difference between Group A and Group B (F=6.235; p=0.023), with higher β-endorphin changes in Group A, compared to Group B. During the competitive show jumping sessions, one-way RM ANOVA showed significant effects of exercise on β-endorphin changes (F=51.10; p<0.001). The statistical analysis, in Group A, showed a significant difference between post-competition training and competitive exercise (F=6.32; p=0.024) with higher β-endorphin values in competitive sessions compared to those of post-competition training. Conclusion: Lactate concentrations seem to be the main factors being correlated with the raise of β-endorphin during anaerobic exercise of competitive events. Exercise of low intensity, as well as that one of training sessions, does not appear to stimulate a significant increased release of β-endorphin and it may depend on the duration of the exercise program. Moreover, the responses during exercise in the course of post-competition training sessions seem to be significantly different from those the pre-competition training. These data show that the preliminary competitive stress induced additional significant changes of β-endorphin pattern. It would reflect the need of a long-lasting modulation of fatigue and pain perception related to the effect of an additional physical and mental effort for the consecutive competitive and training sessions.

To compare the effects of 5% lidocaine patches and placebo patches on pain intensity and electromyographic (EMG) activity of an active myofascial trigger point (MTrP) of the upper trapezius muscle. Thirty-six patients with a MTrP in the upper trapezius muscle were randomly divided into two groups: 20 patients received lidocaine patches (lidocaine group) and 16 patients received placebo patches (placebo group). They used the patches for 12 h each day, for 2 weeks. The patch was applied to the skin over the upper trapezius MTrP. Spontaneous pain, pressure pain thresholds, pain provoked by a 4-kg pressure applied to the MTrP and trapezius EMG activity were measured before and after treatment. Baseline spontaneous pain values were similar in both groups and significantly lower in the lidocaine group than the placebo group after treatment. The baseline pressure pain threshold was significantly lower in the lidocaine group, but after treatment it was significantly higher in this group. Baseline and final values of the pain provoked by a 4-kg pressure showed no significant difference between the groups. Baseline EMG activity at rest and during swallowing of saliva was significantly higher in the lidocaine group, but no significant difference was observed after treatment. Baseline EMG activity during maximum voluntary clenching was similar in both groups, but significantly higher in the lidocaine group after treatment. These clinical and EMG results support the use of 5% lidocaine patches for treating patients with MTrP of the upper trapezius muscle.

2012-01-01

Background The goal of our study is to evaluate the effects of antioxidant vitamins (vitamin C and E), Coenzyme Q10 (CoQ10) and dexamethasone (Dxm) in experimental rat models with pulmonary contusion (PC). Methods Rats were randomly divided into six groups. Except for the control, all subgroups had a moderate pulmonary contusion. Animals in the group I and group II received intraperitoneal saline, group III received 10mg.kg-1 CoQ10 group IV received 100mg.kg-1 vitamin C, group V received 150mg.kg-1 vitamin E, and group VI received 10mg.kg-1 Dxm. Blood gas analysis, serum nitric oxide (NO) and malondialdehyde (MDA) levels as well as superoxide dismutase (SOD) activity assays, bronchoalveolar lavage (BAL) fluid and histopathological examination were performed. Results Administration of CoQ10 resulted in a significant increase in PaO2 values compared with the group I (p = 0.004). Levels of plasma MDA in group II were significantly higher than those in the group I (p = 0.01). Early administration of vitamin C, CoQ10, and Dxm significantly decreased the levels of MDA (p = 0.01). Lung contusion due to blunt trauma significantly decreased SOD activities in rat lung tissue compared with group I (p = 0.01). SOD levels were significantly elevated in animals treated with CoQ10, Vitamin E, or Dxm compared with group II (p = 0.01). Conclusions In our study, CoQ10, vitamin C, vitamin E and Dxm had a protective effect on the biochemical and histopathological outcome of PC after experimental blunt thorax trauma. PMID:23013526

The purpose of this study was to determine the effect of uncinectomy without sinusotomy and natural ostial dilatation on maxillary sinus ventilation in chronic rhinosinusitis. Twenty patients with chronic rhinosinusitis were included in this study. The patients were randomly divided into two groups. Group 1 consisted of patients with uncinectomy (n = 10), while group 2 was made up of patients treated with natural ostial dilatation (n = 10). The CO(2) tension and pressure levels of the maxillary sinus during inspiration and expiration phases were obtained and compared before and after the procedures within and between the groups. The mean CO(2) tension levels in both groups were significantly decreased after the procedures. The mean maxillary sinus pressure during inspiration was significantly decreased to a negative value after uncinectomy; however, no significant change was observed during expiration. There were no significant changes in maxillary sinus pressures after natural ostial dilatation procedure. Both uncinectomy and natural ostial dilatation seem to be equally effective in decreasing maxillary sinus pCO(2) levels. The effects of decreased maxillary sinus pressure during inspiration after uncinectomy on mucociliary clearance and development mechanisms of chronic rhinosinusitis seem to be worth investigating.

To study the potential effects of intensity modulated radiation therapy (IMRT) on clinical efficacy, oral mucosa reaction and immunological foundation; and to explore the effect of immunological changes on clinical efficacy and oral mucosa reaction in patients with nasopharyngeal carcinoma.
 Methods: A total of 200 patients with nasopharyngeal carcinoma, who came from First Department of Nasopharyngeal Radiotherapy, the First People's Hospital of Foshan from October 2008 to November 2011, were selected. The patients were treated with nasopharyngeal radiotherapy, and divided into an observation group and a control group (n=100 in each group). The control group underwent common conventional two-dimensional radiotherapy treatment, while the observation group underwent IMRT. The 5-year survival rates and recurrence rates were recorded at follow-up. After the radiotherapy, the oral mucosa in the patients were evaluated by the classification standard of acute radioactive mucositis by American Radiotherapy Oncology Group (RTOG), and the number of T lymphocyte subsets before and after treatment was detected.
 Results: There were significant difference in non-regional-recurrence survival rate, disease-free survival rate, local recurrence rate between the above 2 groups (all P<0.05), but no significant difference in the distant metastasis-free survival rate (P>0.05). The acute oral mucosa reactions of grade 1, 2, 3, 4 in the control group were 8.00%, 20.00%, 12.00%, 7.00%, respectively, and those were 7.00%, 22.00%, 15.00%, 1.00% respectively. There was no significant difference in the acute response of oral mucosa in grade 1, 2 and 3 in the 2 groups (all P>0.05), but there was significant difference in the grade 4 (P<0.05). There were significantly difference in CD8+, CD4+/ CD8+ and CD4+ T lymphocyte subsets before and after treatment in the above 2 groups (all P<0.01); there were also significantly difference after treatment between the observation group and the control group (all P<0.01).
 Conclusion: In the process of treatment in patients with nasopharyngeal carcinoma, the use of IMRT on the basis of chemotherapy is more effective than the conventional two-dimensional radiotherapy, which can reduce the proportion of grade 4 (severe) acute oral mucosa reaction. It may be related to the protective effect of IMRT on immune function in the patients.

The purpose of this research was to investigate the effects of exercise capacity, heart rate recovery and heart rate variability after high-intensity exercise on caffeine concentration of energy drink. The volunteers for this study were 15 male university student. 15 subjects were taken basic physical examinations such as height, weight and BMI before the experiment. Primary tests were examined of VO2max per weight of each subjects by graded exercise test using Bruce protocol. Each of five subject was divided 3 groups (CON, ECGⅠ, ECGⅡ) by matched method based on weight and VO2max per weight what gained of primary test for minimize the differences of exercise capacity and ingestion of each groups. For the secondary tests, the groups of subjects were taken their materials before and after exercise as a blind test. After the ingestion, subjects were experimented on exercise test of VO2max 80% by treadmill until the all-out. Heart rate was measured by 1minute interval, and respiratory variables were analyzed VO2, VE, VT, RR and so on by automatic respiratory analyzer. And exercise exhaustion time was determined by stopwatch. Moreover, HRV was measured after exercise and recovery 3 min. Among the intake groups, ECGⅡ was showed the longest of exercise exhaustion time more than CON group (p = .05). Result of heart rate during exercise according to intake groups, there was significant differences of each time (p < .001), however, not significant differences of each groups and group verse time (p > .05). Result of RPE during exercise according to intake groups, there was significant differences of each time (p < .001), however, not significant differences of each groups and group verse time (p > .05). In conclusion, EDGⅡ showed the significant increase of exercise exhaustion time more than CON group (p=.05) and not significant differences in HR, RPE, RER, HRV, HRR, blood pressure (p > .05). Therefore, 2.5 mg/kg(-1) ingestion of energy drink might be positive effect to increase exercise performance capacity without side-effect in cardiovascular disease.

We aimed to investigate whether agoraphobia (A) in panic disorder (PD) has any effects on oxidative and anti-oxidative parameters. We measured total antioxidant capacity (TAC), paraoxonase (PON), arylesterase (ARE) antioxidant and malondialdehyde (MDA) oxidant levels using blood samples from a total of 31 PD patients with A, 22 PD patients without A and 53 control group subjects. There was a significant difference between the TAC, PON, ARE and MDA levels of the three groups consisting of PD with A, PD without A and the control group. The two-way comparison to clarify the group creating the difference showed that the TAC, PON, and ARE antioxidants were significantly lower in the PD with A group compared to the control group while the MDA oxidant was significantly higher. There was no significant difference between the PD without A and control groups for TAC, PON, ARE and MDA levels. We clearly demonstrated that the oxidative stress and damage to the anti-oxidative mechanism are significantly higher in the PD group with A. These findings suggest that oxidative/anti-oxidative mechanisms may play a more important role on the pathogenesis of PB with A. PMID:24474979

The comparative effects of chronic [28 days] consumption of kola nut and its active constituent, caffeine diets on locomotor behaviour and body weights in mice were investigated. Thirty adult Swiss white mice [15-30 g body weight], were used for the study. The open field-maze was employed for the evaluation of locomotor behaviour. Mice in the control group [n=10] were fed normal rodent chow, mice in the kola nut-fed group [n=10] were fed kola diet [25 % wt/wt of rodent chow] while those in the caffeine-fed group [n=10] were fed caffeine diet [0.66% wt/wt of rodent chow] for 4 weeks. All animals were allowed free access to clean drinking water. Daily food intake, water intake and body weight change were also measured. Daily food intake in the kola nut and caffeine-fed group of mice was significantly [P<0.001 respectively] lower than the control. There was also a significant [P<0.001] decrease in daily water intake in the caffeine-fed group compared to the control whereas, the apparent decrease of water intake in the kola nut-fed group was not significantly different from the control. Body weight change was also significantly [P<0.001 and P<0.05 respectively] lower in the kola nut and caffeine-fed groups of mice when compared to the control. The frequency of rearing in the open field was significantly [P<0.01] lower in the caffeine-fed group of mice when compared to the control. The frequency of grooming was also significantly [P<0.05] lower in the caffeine-fed group of mice when compared to the control. There was also a significant [P<0.05] decrease in the frequency of light-dark transitions in the light/dark transition box for the caffeine-fed group when compared to the control. The results showed that chronic consumption of kola nut and caffeine diets caused decrease in food intake and body weight. Consumption of caffeine-diet also significantly decreased water intake and locomotor activity. The effect of kola nut-diets on water intake and locomotor activity was not significant. Hence, the effect of kola nut on locomotor behaviour and water intake may not be due to caffeine only.

AIM: The aim of the study was to confirm the efficiency and safety of the fractional CO2 laser in skin renewal and to check the possibility of having a synergistic effect in patients who besides carbon dioxide laser are treated with PRP (platelet-rich plasma) too. MATERIAL AND METHODS: The first group (Examined Group 1 or EG1) included 107 patients treated with fractional CO2 laser (Lutronic eCO2) as mono-therapy. The second group (Control Group or CG) covered 100 patients treated with neither laser nor plasma in the same period but subjected to local therapy with drugs or other physio-procedures under the existing protocols for treatment of certain diseases. The third group (Examined Group 2 or EG2) treated 25 patients with combined therapy of CO2 laser and PRP in the treatment of facial rejuvenation or treatment of acne scars. RESULTS: Patient’s satisfaction, in general, is significantly greater in both examined groups (EG1 and EG2) (p < 0.001). It was found the significant difference between control and examined group from the treatment in acne scar (Fisher exact two tailed p < 0.001). Patients satisfaction with the treatment effect in rejuvenation of the skin is significant (χ2 = 39.41; df = 4; p < 0.001). But, patients satisfaction from the treatment with HPV on the skin was significantly lower in examined group (treated with laser), p = 0.0002. CONCLUSION: Multifunctional fractional carbon dioxide laser used in treatment of patients with acne and pigmentation from acne, as well as in the treatment of scars from different backgrounds, is an effective and safe method that causes statistically significant better effect of the treatment, greater patients’ satisfaction, minimal side effects and statistically better response to the therapy, according to assessments by the patient and the therapist.

White tea (WT) is very similar to green tea (GT) but it is exceptionally prepared only from the buds and young tea leaves of Camelia sinensis plant while GT is prepared from the matured tea leaves. The present study was investigated to examine the effects of a 0.5% aqueous extract of WT in a streptozotocin-induced diabetes model of rats. Six-week-old male Sprague-Dawley rats were divided into 3 groups of 6 animals in each group namely: normal control (NC), diabetic control (DBC) and diabetic white tea (DWT). Diabetes was induced by an intraperitoneal injection of streptozotocin (65 mg/kg BW) in DBC and DWT groups except the NC group. After 4 weeks feeding of 0.5% aqueous extracts of WT, the drink intake was significantly (P<0.05) increased in the DWT group compared to the DBC and NC groups. Blood glucose concentrations were significantly decreased and glucose tolerance ability was significantly improved in the DWT group compared to the DBC group. Liver weight and liver glycogen were significantly increased and serum total cholesterol and LDL-cholesterol were significantly decreased in the DWT group compared to the DBC group. The food intake, body weight gain, serum insulin and fructosamine concentrations were not influenced by the consumption of WT. Data of this study suggest that the 0.5% aqueous extract of WT is effective to reduce most of the diabetes associated abnormalities in a steptozotocin-induced diabetes model of rats.

Dysmenorrhea is the most common cyclic pelvic pain, and it affects the quality of life of many women. We sought to compare the effects of massage and isometric exercises on primary dysmenorrhea. We conducted a randomized controlled trial at the dormitories of Shiraz University among 102 students with primary dysmenorrheal. The student groups were randomly divided into massage, isometric exercises, and control groups. The first group received 2 consecutive cycles of effleurage massage with lavender oil. The second group had 8 weeks of isometric exercises. No intervention was performed for the control group. Pain intensity was measured and recorded by using a visual analog scale. In addition, the duration of pain was measured in hours, and Spielberger's questionnaire was used to measure the anxiety level. Pain intensity had significantly reduced in the massage and exercises groups; the reduction was more significant in the massage group (P < .001). The results revealed a significant difference among the 3 groups in regard to the mean duration of pain after the third cycle (P = .006). However, no significant difference was found among the 3 groups concerning the mean level of anxiety. The results of intragroup comparisons only showed a significant reduction of anxiety level in the massage group after the third cycle (P = .017). Based on the present findings, it seems that massage therapy and isometric exercises were effective in reducing some symptoms of dysmenorrhea.

Because the choice of anesthetic affects the rodent orthotopic liver transplantation (OLT) model, we compared the effects of isoflurane, ketamine, chloral hydrate, and pentobarbital on the OLT model. OLT was performed using the two-cuff technique. Two hundred male rats were randomly divided into five groups: control, isoflurane, ketamine, chloral hydrate, and pentobarbital groups. Rectal temperatures, respiratory rates, arterial blood values (pH, PaCO 2 , PaO 2 , and SatO 2 ), liver function tests and histopathology, recovery times, and anhepatic stage mortality rates were assessed. Compared with controls, respiratory rates decreased by 20% in the isoflurane group, and decreased by 40%-50% in the ketamine, chloral hydrate, and pentobarbital groups. The PaO 2 , SatO 2 , and pH levels in the ketamine, chloral hydrate, and pentobarbital groups were significantly lower than those in the isoflurane and control groups (P < .05). Only the pentobarbital group displayed significant liver histopathologic changes along with significantly higher levels of serum alanine aminotransferase and total bilirubin, but a significantly lower level of serum albumin, compared with the control group (P < .05). The isoflurane group had a 0% anhepatic stage mortality rate compared with rates of 30%-40% in the other anesthetic groups. Isoflurane should be the preferred anesthetic for rodent OLT surgery due to its minimal respiratory and hepatic physiological effects as well as its low anhepatic phase mortality rate. Secondary to isoflurane, ketamine and chloral hydrate may be administered as donor anesthetics. Pentobarbital use should be avoided entirely in rodent OLT surgery due to its significant hepatotoxic effects. Copyright © 2016 Elsevier Inc. All rights reserved.

[Purpose] This study aimed to determine the effect of mirror therapy (MT) with transcranial direct current stimulation (tDCS) on the recovery of the upper extremity function of chronic stroke patients. [Subjects] Twenty-seven patients at least 6 months after stroke onset were divided randomly into an experimental group (14 patients) and a control group (13 patients). [Methods] All subjects received tDCS for 20 min followed by a 5 min rest. Then the experimental group received MT while the control group conducted the same exercises as the experimental group using a mirror that did not show the non-paretic upper extremity. The groups performed the same exercises for 20 min. All subjects received this intervention for 45-min three times a week for 6 weeks. [Results] After the intervention, the experimental group showed significant improvements in the box and block test (BBT), grip strength, and the Fugl-Meyer assessment (FMA), and a significant decrease in the Jebsen-Taylor test. The control group showed a significant increase in grip strength after the intervention, and a significant decrease in the Jebsen-Taylor test. Comparison of the result after the intervention revealed that the experimental group showed more significant increases in the BBT and grip strength than the control group. [Conclusion] These results show that MT with tDCS has a positive effect on the functional recovery of the upper extremity of stroke patients, through activating motor regions in the brain, and thus plays an important role in recovery of neuroplasticity.

To evaluate the effectiveness or acellular dermal matrix (ADM) with autologous buccal micro mucosa and micro skin graft in vaginoplasty. A retrospective analysis was made on the clinical data of 67 patients with vaginal agenesis treated between July 2006 and June 2013. ADM and mixed particles were used in 20 cases (ADM group) and mixed particles graft in 47 cases (control group) in vaginoplasty. There was no significant difference in age between 2 groups (t=0.233, P=0.816). The depth, diameter, and volume of neovagina, epithelization time, stent needing time, and female sexual function index (FSFI) score were compared between 2 groups. There was no significant difference in operation time and amount of bleeding between 2 groups (t = -1.922, P = 0.059; t = 0.398, P = 0.692). The patients were followed up 11-38 months (mean, 16.08 months). Fifteen cases in ADM group and 29 cases in control group had sexual life after operation. Bleeding after operation occurred in 6 cases (2 in ADM group and 4 in control group). No stenosis was observed. Difference in epithelization time was not statistically significant (t = -1.938, P = 0.057). However, the stent needing time of ADM group was significantly shorter than that of control group (t = 7.020, P = 0.000). The neovagina was ideal in wetness degree, smoothness, flexibility, and hairlessness during follow-up. The depth, diameter, and volume of vagina had no significant difference between 2 groups (P > 0.05) at last follow-up, which were close to normal vagina. The other patients had normal sexual function except 1 patient whose FSFI score was less than 23; no statistically significant difference was found in FSFI score between 2 groups (P > 0.05). On the basis of mixed particles grafting, the ADM could improve trestle structure for resisting contracture. The effectiveness is better than merely mixed particles graft. The procedure has satisfactory anatomical and functional results.

The challenges of research into brain-computer interfaces (BCI) include significant individual differences in learning pace and in the effective operation of BCI devices. The use of neurofeedback training is a popular method of improving the effectiveness BCI operation. The purpose of the present study was to determine to what extent it is possible to improve the effectiveness of operation of sensorimotor rhythm-based brain-computer interfaces (SMR-BCI) by supplementing user training with elements modifying the characteristics of visual feedback. Four experimental groups had training designed to reinforce BCI control by: visual feedback in the form of dummy faces expressing emotions (Group 1); flashing the principal elements of visual feedback (Group 2) and giving both visual feedbacks in one condition (Group 3). The fourth group participated in training with no modifications (Group 4). Training consisted of a series of trials where the subjects directed a ball into a basket located to the right or left side of the screen. In Group 1 a schematic image a face, placed on the controlled object, showed various emotions, depending on the accuracy of control. In Group 2, the cue and targets were flashed with different frequency (4 Hz) than the remaining elements visible on the monitor. Both modifications were also used simultaneously in Group 3. SMR activity during the task was recorded before and after the training. In Group 3 there was a significant improvement in SMR control, compared to subjects in Group 2 and 4 (control). Differences between subjects in Groups 1, 2 and 4 (control) were insignificant. This means that relatively small changes in the training procedure may significantly impact the effectiveness of BCI control. Analysis of behavioural data acquired from all participants at training showed greater effectiveness in directing the object towards the right side of the screen. Subjects with the greatest improvement in SMR control showed a significantly lower difference in the accuracy of rightward and leftward movement than others.

Purpose To evaluate the effectiveness of tramadol for the reduction of pain in panretinal photocoagulation (PRP). Methods A double-masked randomized controlled study was performed. Fifty-eight eyes in 29 patients with proliferative diabetic retinopathy were enrolled. The eyes of the patients were randomized into two groups. Group A received an empty capsule. Group B received an oral intake of 100 mg tramadol. The capsule used in Group A had the same appearance as that used in Group B. Pain during PRP was assessed using a visual analog scale. Vital signs, including blood pressure and heart rate, were measured. Results The mean pain scores for groups A and B were 4.80±2.10 and 3.83±1.82 (p=0.09). There were no significant differences in the mean pain scores between the two groups. More patients in group A complained of greater pain than moderate intensity (visual analogue scale=4). Systemic blood pressure increased significantly in group A after laser treatment. However, there were no significant differences in the diastolic blood pressure changes between the two groups. We found no statistical correlation in the heart rate changes. Conclusions We failed to prove that tramadol is effective for pain relief because of the small sample size. However, tramadol was effective for the relief of more severe pain. It was also found to stabilize vital sign changes, such as systolic blood pressure during PRP. PMID:20046687

Nutraceuticals containing cis-9-cetylmyristoleate (CMO) are used to improve knee pain despite the lack of placebo-controlled studies in humans. The aim of the study was to explore the minimal effective dose of CMO for relieving knee joint pain. Twenty-eight subjects with mild degree arthritic knee joint pain were randomized into 4 groups; groups A, B, and C that contained 100%, 80%, and 62.4% of fatty acid component with 12.5% of CMO, and control group D (starch 100%). The pain intensity, functional disability, and the Patient Global Impression of Change (PGIC) were assessed for a 12-week ingestion period. Compared to group D (n = 6), there were significant differences in pain score in group A (n = 7, P = 0.005) and group C (n = 7, P = 0.012), but not significant in group B (n = 6, P = 0.180). Western Ontario and McMaster Universities Arthritis (WOMAC) score decreased significantly in groups A and C. The PGIC was positive in the majority (>50%) in groups A, B, and C, whereas negative in 83.3% in group D (control). CMO is effective in alleviating knee pain in persons with mild degree arthritis of the knee joint, at an effective dose of 62.4%.

The aim of this study is to clarify the effects of cevimeline on various components in human saliva, such as immunoglobulin A (IgA), lysozyme, alpha-amylase and squamous cell carcinoma (SCC) antigen. Twelve female patients with Sjögren syndrome (SS) and 14 healthy women were enrolled. After the first saliva collection, one capsule (30 mg) of cevimeline was administered to each subject. Saliva was collected again after 90 min. The salivary flow rate and concentration of each component were measured. In both groups the salivary flow rate and amylase concentration were significantly increased by cevimeline. The lysozyme and IgA concentrations did not change significantly in both groups. The SCC antigen concentration did not change significantly in the SS group, but it decreased significantly in the control group. The secretion rates of amylase and IgA showed significant increases in both groups. The secretion rate of lysozyme significantly increased only in the control group, while the secretion rate of SCC significantly increased only in the SS group. Cevimeline augments not only the salivary flow rate but also the secretion rate of some digestive and/or defense factors from infections. It may be beneficial for SS patients to continue taking cevimeline to prevent oral infections, and other serious sequelae. Copyright (c) 2005 S. Karger AG, Basel.

Whether selective serotonin reuptake inhibitors (SSRIs) exposure during adolescent brain development causes lasting effects remains unresolved. Assess the effects of fluoxetine and paroxetine 60 days after adolescent exposure compared with when on-drug. Male Sprague-Dawley littermates (41 litters) were gavaged on postnatal days 33-53 with fluoxetine (3 or 10 mg/kg/day), paroxetine (3, 10 or, 17 mg/kg/day), or water; half were tested while on-drug (21 litters) and half after 60 days off-drug (20 litters). The highest dose of the drugs reduced body weight gain during treatment that rebounded 1 week post-treatment. On-drug, no significant group differences were found on elevated plus maze time-in-open, zone entries, or latency to first open entry; however, the high dose of paroxetine significantly reduced head-dips (N=20/group). No significant effects were found on-drug for acoustic startle response/prepulse inhibition (ASR/PPI) although a trend (p<0.10) was seen, which after combining dose levels, showed a significant increase in ASR amplitude for both fluoxetine and paroxetine (N=20-21/group). No differences on immobility time were seen in the Porsolt forced swim test or in plasma corticosterone at the end of forced swim (N-19-21/group). Off-drug, no effects were seen in the elevated plus maze (N=16/group), ASR/PPI (N=20/group), forced swim (N=19-20/group), or plasma corticosterone (N=19/group). At the doses tested, fluoxetine and paroxetine induced minor effects with drug on-board but no residual, long-term adverse effects in rats 60 days after drug discontinuation. The data provide no evidence that fluoxetine or paroxetine have long-term adverse effects on the behaviors measured here after adolescent to young adult exposure.

We evaluated the efficacy of loxoprofen sodium for refractory nocturia. Twelve men (mean age, 75.1 +/- 5.7) with nocturia were enrolled in this study. All patients received 60 mg loxoprofen sodium prior to sleeping at night for 14 days. Nine of 12 patients (75%) felt more satisfaction than previous treatments. Patients were grouped into a loxoprofen sodium-effective (n = 7) and ineffective groups (n = 5) based on the results of the frequency-volume chart. In the effective group, interestingly, night-time urine volume showed significant reduction (P < 0.05). On the other hand, the average single voided volume at night and 24-h urine volume showed no significant change. There was a statistically significant difference in the night-time urine volume after treatment between groups (P < 0.01). Loxoprofen sodium is an effective treatment for some patients with refractory nocturia. The main effect mechanism of loxoprofen sodium may involve the reduction of night-time urine production.

This study was designed to investigate the effects of 2450 MHz EMR on the heart and blood in rat and possible ameliorating effects of melatonin. Thirty-two female Wistar Albino rats were randomly grouped (by eight in each group) as follows:  Group I: cage-control group (dimethysulfoxide (DMSO), 10mg/kg/day i.p. without stress and EMR. Group II: sham-control rats stayed in restrainer without EMR and DMSO (10mg/kg/day i.p.). Group III: rats exposed to 2450 MHz EMR. Group IV: treated group rats exposed to 2450 MHz EMR+melatonin (MLT) (10mg/kg/day i.p.). In the blood tissue, there was no significant difference between the groups in respect of erythrocytes GSH, GSH-Px activity, plasma LP level and vitamin A concentration (p > 0.05). However, in the Group IV, erythrocytes' LP levels (p < 0.05) were observed to be significantly decreased while plasma vitamin C, and vitamin E concentrations (p < 0.05) were found to be increased when compared to Group III. In the heart tissues, MDA and NO levels significantly increased in group III compared with groups I and II (p < 0.05). Contrary to these oxidant levels, CAT and SOD enzyme activities decreased significantly in group III compared with groups I and II (p 0.05). Besides, MLT treatment lowered the MDA and NO levels compared with group III. In conclusion, these results demonstrated that contrary to its effect on the heart, the wireless (2450 MHz) devices cause slight oxidative-antioxidative changes in the blood of rats, and a moderate melatonin supplementation may play an important role in the antioxidant system (plasma vitamin C and vitamin E). However, further investigations are required to clarify the mechanism of action of the applied 2450 MHz EMR exposure (Tab. 3, Fig. 1, Ref. 49).

To investigate the effect of Jiangzhi tablet on serum indexes of mice with fatty liver induced by CCL4, 60 mice were randomly divided into blank control group, model group, positive group, high, middle and low dose group. High fat diet fed mice for 2 weeks, in second the beginning of the weekend, each group of experimental animal except the blank group in the afternoon 1:00 subcutaneous injection of 40% CCl4 of edible oil (0.05 mL/10g, 2 times / week) for modeling; at the same time, 9:00 in the morning to lipid-lowering tablets LARGEMEDTUM and small dose group (0.1125g/ml, 0.05625g/ml, 0.02815g/ml) and Gantai tablet group (0.045g/ml) mice fed with corresponding drugs, the model group received the same volume of physiological saline. At the end of the fifth week, the eyeballs were collected and the serum was separated. The levels of serum triglyceride, high density lipoprotein, low density lipoprotein, serum AST, ALT and ALP were detected. Compared with the model group, Dongbao Gantai group, Jiangzhi tablets, high dose group had significantly decreased TG and LDL content in serum of mice (p<0.01), significantly increased the content of HDL (p<0.01); Jiangzhi tablets low dose group can significantly reduce TG and LDL content in serum (p<0.05), high HDL content increased significantly in the serum of mice (p<0.01). Dongbao Gantai group, Jiangzhi tablet high dose group and middle dose group could significantly reduce the content of ALT, ALP, AST in serum of mice (p<0.01), lipid-lowering tablets in small dose group can significantly reduce ALP and AST content in serum (p<0.01), decreased the content of ALT in serum of mice (p<0.05). The high, middle and low dose groups of Jiangzhi tablets have a better intervention effect on the mice model of fatty liver induced by small dose of carbon tetrachloride.

The purpose of this study was to investigate the effect of circuit exercise training and detraining, which is defined by termination of training without additional physical activities, in type 2 diabetic patients. Elderly with type 2 diabetes were divided into a group that exercised for 1 h three times a week for 12 weeks, followed by detraining for 8 weeks, or into a control group. Muscular strength, endurance, flexibility, agility, balance, body mass index (BMI), glycosylated hemoglobin (HbA1c), and blood lipid profile were measured. Of the 98 diabetic participants who joined this study, 37 patients completed the program (exercise group = 24, control group = 13). After training, muscular strength, flexibility, balance, agility, and endurance in the training group were significantly higher than at baseline and compared to the control group. HbA1c levels decreased in the training group. There was no significant improvement in BMI and blood lipid profile in either group. Flexibility and agility in the training group declined significantly after detraining. In spite of this decline, flexibility and agility were significantly higher compared to the baseline and to the control group. In type 2 diabetic patients, circuit training had a beneficial effect on the indices of physical function and glucose metabolism. Training resulted in good improvement; and during detraining, the effect of exercise training was maintained except in some parameters.

This study examined the effectiveness of rational emotive behavior coaching (REBC) on occupational stress and work ability in a sample of electronics workshop instructors in Nigeria. A pretest-posttest control group design was used. The participants were 108 electronics workshop instructors in technical colleges in the south-east of Nigeria who met the study inclusion criteria. Data were collected using 3 questionnaires and analyzed using a repeated measure analysis of variance and Mann-Whitney U test. REBC led to a significant reduction in occupational stress experienced by the electronics workshop instructors in the REBC group compared to their counterparts in the waitlist control group. Furthermore, the scores for occupation-related irrational beliefs of the instructors in the REBC group were significantly lower than those in the waitlist control group at the end of the coaching intervention. The work ability of the REBC group was significantly better than that of the waitlist control group. Finally, the effects in the REBC group were significantly sustained at 3-month follow-up. REBC is a time-efficient and solution-focused therapeutic modality for assisting occupationally stressed employees in a Nigerian setting. REBC can be used for improving and maintaining work ability of workers. The researchers hope that occupational health professionals and health counselors would extend this approach to tackle psychological issues limiting employees' effectiveness and performance in the Nigerian work environment and in other countries.

This study assessed the efficacy of a school-based healthy lifestyle intervention (Sport for LIFE) for increasing physical activity, decreasing sedentary behaviour, reducing screen time behaviour, encouraging healthy attitudes and behaviour to nutrition, and reducing body mass index (BMI) in 8-9-year-old primary school children from lower socioeconomic backgrounds in Northern Ireland. A non-randomised controlled trial of 416 children from 24 schools took part. Schools were randomly assigned to one of two groups, an intervention or control group with 12 schools in each group. The intervention group received a 12-week school-based programme based on social cognitive theory. At baseline and follow-up, groups completed questionnaires assessing physical activity, screen time behaviour and dietary patterns. On each occasion anthropometric assessments of height and weight were taken. Physical activity and sedentary behaviour were measured by accelerometry. Significant effects were observed for vigorous, moderate and light activity for the intervention group at follow-up. Sedentary behaviour was significantly reduced for the intervention group but not for the control group. No significant effects of the intervention on BMI, screen time behaviour or attitudes to nutrition, with the exception of non-core foods, were shown. The programme was effective in increasing physical activity and reducing sedentary behaviour, however no significant changes in screen time behaviour and attitude to nutrition, with the exception of non-core foods, were observed. Future research ideas are offered for tackling low levels of physical activity in children.

The objective of this study was to test the effect of sugar-free chewing gum sweetened with xylitol or maltitol compared to the use of a gum base or no gum on gingivitis and plaque scores under both brushing and non-brushing circumstances. The design of the study was a four-group, double-blinded, randomized controlled study with a 3-week duration. In each group, the participants did not brush the teeth in the lower jaw designated to develop experimental gingivitis, while maintaining normal oral hygiene procedures in the upper jaw. After professional dental prophylaxis, the participants were allocated into one of four groups (xylitol, maltitol, gum base or no gum). Chewing gum was used five times a day for 10 min. 220 participants completed the study and provided evaluable data. The increase in bleeding on marginal probing (BOMP) and plaque scores (PS) in the non-brushed (lower) jaw with experimental gingivitis was significant in all groups (P < 0.001). As compared to the gum base, the increase in BOMP in the xylitol and maltitol group was significantly lower. In the brushed upper jaw, no significant changes for BOMP were observed from the baseline to the end point of the study, and there were no significant differences in BOMP and PS between the groups. In circumstances where regular brushing is performed, no effect of chewing gum was observed on bleeding and plaque scores. In the absence of brushing, chewing xylitol or maltitol gum provided a significant inhibitory effect on gingivitis scores compared to chewing gum base. The difference when compared to the group not using gum was not significant. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Prolonged exposure to retinyl acetate (RA) in the diet inhibits the development of 7,12-dimethylbenz(a)anthracene (DMBA)-induced mammary cancers in rats. The effectiveness of RA was examined when given 6 months after the administration of DMBA. Non-inbred female Sprague-Dawley rats with DMBA-induced mammary tumors were divided into 3 groups and treated for 4 weeks as follows: Group 1 served as controls, group 2 was ovariectomized, and group 3 received 328 mg RA/kg diet. Ovariectomy (OVX) markedly reduced both the number and size of the tumors. RA administration failed to induce any significant regression in tumor number but significantly retarded tumor growth whenmore » compared to tumor growth in group 1 controls. The levels of estradiol, progestin, and prolactin (PRL) receptors were significantly reduced after OVX, whereas only the levels of PRL receptors declined significantly after RA administration. Circulating progesterone concentrations were not affected in the RA-treated group but the plasma PRL level was significantly increased. The present studies show that if treatment with RA is delayed until 6 months after carcinogen administration, the protective effect of RA can still be observed although its effectiveness is less dramatic than when it is administered earlier.« less

Compared with Risperidone, Quetiapine's effectiveness and safety on treating alcohol-induced mental disorder is still unclear. To investigate the clinical effectiveness and safety of Quetiapine on treating alcohol-induced mental disorder. One hundred and forty-eight patients with alcohol-induced mental disorder were divided into the experimental group (75 patients) and the control group (73 patients) by the treatments they received. The patients in the experimental group were treated with Quetiapine by taking it three times per day orally. The mean (sd) maintenance dose was 151.2(27.3) mg/d, and the treatment cycle was 6 weeks. Patients in the control group received Risperidone once per day orally with a mean (sd) maintenance dose being 2.3(0.9) mg/d, and the treatment cycle was 6 weeks as well. The PANSS scale was used to assess patients' before and after treatment. The researchers also observed any adverse reactions in both treatment strategies and evaluated the effectiveness and safety of both treatment strategies. The mean (sd) PANSS scale score of the experimental group after two weeks of treatment was 71.9 (10.2), which was clearly better than the mean (sd) score before treatment (82.6 [11.4]), and was significantly better than the control group's mean (sd) score after two weeks (76.5[12.8]). Also, the experimental group's scores after 4 weeks of treatment and 6 weeks of treatment were significantly better than the control group. The experimental group's efficacy rate (94.7%) was higher than the control group's (90.4%); the cure rate of the experimental group (33.3%) was higher than that of the control group (24.7%), and the difference was statistically significant. The rates of adverse reactions in the experimental and control groups were 13.3% and 19.2% respectively, and they were significantly different from each other. Treating alcohol-induced mental disorder with Quetiapine is more effective than treating it with Risperidone. Quetiapine can improve patients' symptoms quickly, and lower the chance of adverse reactions. It is effective and safe.

There was a significant difference between group II and other two groups regarding average number of ovulatory follicles >18 mm (2.25 versus 1.75 and 1.89, respectively), but no significant difference between the three study groups regarding number of intermediate follicles 14-18 mm (4, 10 and 4, respectively). There was no significant difference between the three study groups regarding occurrence and laterality of ovulation, pregnancy rate per cycle but a significant difference between group II and other two groups regarding pregnancy rate per patient (20% versus 10% and 10%, respectively, p value 0.05). There was a highly statistically significant difference between group II and other two groups regarding peak endometrial thickness (7.3 ± 1.1 versus 5.4 ± 0.6 and 5.3 ± 0.6, respectively). NAC as an adjuvant to CC for induction of ovulation improves ovulation and pregnancy rates in PCOS patients with beneficial impacts on endometrial thickness.

The aim of this study was to investigate the antioxidant effects of tempol on ovarian ischemia-reperfusion (I/R) injury in rats. Forty female Wistar albino rats were randomly divided into 5 groups: Group I, sham; Group II, ischemia (I); Group III, I/R; Group IV, I/R + tempol 30 mg/kg i.p; Group V, I/R + tempol 50 mg/kg i.p. Oxidative stress index (OSI) was significantly higher in the ischemia group and the I/R group than in the sham group. Catalase levels were significantly lower in the I/R group than in the I/R + tempol 30 mg/kg i.p. and the I/R + tempol 50 mg/kg i.p. groups. Glutathione peroxidase levels were lower in the I/R group than in the I/R + tempol 30 mg/kg i.p. and the I/R + tempol 50 mg/kg i.p. groups. MDA levels were significantly lower in the I/R + tempol 30 mg/kg i.p. group and the I/R + tempol 50 mg/kg i.p. group than in the I/R group. The levels of the histopathological parameters were significantly decreased in the I/R + tempol 50 mg/kg i.p. group compared with the I/R group. Tempol can be used for reducing ovarian I/R injury.

Peer effects on risk behaviour: the importance of group identity.

PubMed

Gioia, Francesca

2017-01-01

This paper investigates whether and to what extent group identity plays a role in peer effects on risk behaviour. We run a laboratory experiment in which different levels of group identity are induced through different matching protocols (random or based on individual painting preferences) and the possibility to interact with group members via an online chat in a group task. Risk behaviour is measured by using the Bomb Risk Elicitation Task and peer influence is introduced by giving subjects feedback regarding group members' previous decisions. We find that subjects are affected by their peers when taking decisions and that group identity influences the magnitude of peer effects: painting preferences matching significantly reduces the heterogeneity in risk behaviour compared with random matching. On the other hand, introducing a group task has no significant effect on behaviour, possibly because interaction does not always contribute to enhancing group identity. Finally, relative riskiness within the group matters and individuals whose peers are riskier than they are take on average riskier decisions, even when controlling for regression to the mean.

To investigate whether laughter therapy lowers total mood disturbance scores and improves self-esteem scores in patients with cancer. Randomized controlled trial in a radio-oncology outpatient setting. Sixty-two patients were enrolled and randomly assigned to the experimental group (n=33) or the wait list control group (n=29). Three laughter therapy sessions lasting 60 minutes each. Mood state and self-esteem. The intention-to-treat analysis revealed a significant main effect of group: Experimental group participants reported a 14.12-point reduction in total mood disturbance, while the wait list control group showed a 1.21-point reduction (p=0.001). The per-protocol analysis showed a significant main effect of group: The experimental group reported a 18.86-point decrease in total mood disturbance, while controls showed a 0.19-point reduction (p<0.001). The self-esteem of experimental group was significantly greater than that of the wait list control group (p=0.044). These results indicate that laughter therapy can improve mood state and self-esteem and can be a beneficial, noninvasive intervention for patients with cancer in clinical settings.

The effects of 14 days of increased gravitational load, and the absence of adrenal stress hormones on total body bone mineral content (BMC) were examined in male Sprague-Dawley rats. Centrifugation at 2 Gs (2G) was used to increase the gravitational load, and bilateral adrenalectomy (ADX) was used to eliminate the production of adrenal stress hormones. Stationary groups at 1 G (1G) and sham operated (SHAM) animals served as controls. Thirty rats (n=6 or 8) made up the four experimental groups (1G SHAM, 1G ADX, 2G SHAM and 2G ADX). BMC was assessed by dual energy x-ray absorptiometry (DXA) which was performed to determine the total body bone mineral content, and also through bone ashing of the left femur and the left humerus. Activity was determined through biotelemetry, also body mass and food intake were measured. Multi-factorial analysis of variance (MANCOVA) and Newman Keuls post hoc tests were used to analyze significant effects (p is less than 0.05) for the primary variables. Results from both DXA and the ashed femur indicated that BMC decreased significantly with increased G for both the SHAM and ADX groups. The BMC determined by DXA for the 1G ADX group was also significantly lower than the 1G SHAM group, however the 2G SHAM and 2G ADX groups were not significantly different. However, the bone ashing results showed the femur differed significantly only between the rates of centrifugation and not between the ADX and SHAM. The humerus showed no significant difference between any of the groups. There was a significant decrease in body mass with increased G and there was no ADX effect on body mass. When DXA BMC was normalized for body mass changes, there were no significant group differences. However, with bone ashing, the femur BMC/BW still showed significant difference between rates of centrifugation, with the 2G group being lower. Activity level decreased with body mass, and food intake data showed there was significant hypophagia during the first few days of centrifugation. Urine calcium was measured and was found decrease at the start of centrifugation for the 2G groups and rise to a level higher than that of the stationary groups. Finally, the correlation between BW and BMC was determined to be highly correlated (r = .71). These results suggest that the decrease in total body BMC seen with hypergravity may be based to a large extent on the differences in body mass induced by the 2G load.

The meat quality of 42, 8 month-old cross-bred wether lambs that had been grazed on either predominantly saltbush (Atriplex nummularia) and supplemented with pasture hay (n=14) or oat grain (n=14) for 68 days was compared to lambs grazed predominantly on lucerne (Medicago sativa; n=14). The lambs used in the study ranged in un-fasted liveweight from 44.5 to 63.6kg pre-slaughter. There was no significant (p>0.05) difference between the treatments for liveweight, but there was a significant (p<0.05) treatment effect on hot carcass weight with those from the saltbush/hay group (SH) being lighter than those from the lucerne group. When the carcass measures of fatness or m. longissimus thoracis et lumborum area were adjusted to a common carcass weight of 22.4kg there was no difference between groups. There were no significant differences (p>0.05) between groups for pH or colour values (where L* indicates relative lightness, a* indicates relative redness and b* indicates relative yellowness). There was no significant difference (p>0.05) between groups for b(2)* values of subcutaneous fat. Treatment had a significant effect on aroma strength (p<0.05), samples from lambs in the SH group (n=10) and those in saltbush/grain (SG) group (n=10) having a stronger aroma than those from lambs grazed on lucerne (L; n=10). No treatment effect for liking of aroma was found. Flavour strength was not significantly (p>0.05) stronger for samples from groups SH and SG than for samples from group L. There was no effect of treatment on tenderness or juiciness and overall panellists ranked the samples similarly for acceptability. Finishing lambs on saltbush and either supplemented with hay or grain as used in this experiment did not present any apparent meat quality problems compared to lucerne fed lambs.

To explore the effect of infrared (IR) irradiation on the survival rates of mice under forced swimming in cold conditions. IR irradiation has been found to be beneficial for wound healing, tumor reduction, pain relief, and even against depression. However, whether the antidepressant effect of IR irradiation came from heat has remained unanswered. The goals of the study were originally aimed at using an animal model for depression to understand the relationship between the antidepressant effect of IR irradiation and hyperthermia as well as seasonality. Forty-four mice were housed in cages in a room subject to the outdoor temperature, and randomly assigned to the IR-treated group (n = 15), the heat-treated group (n = 14), and the control group (n = 15) during winter. The mice of the IR-treated group received whole-body IR irradiation for 60 min daily, while the heat-treated group received heat diffusion to reach the same temperature level. The control group received neither IR nor heat. All groups of mice underwent a forced swimming test weekly. Incidentally, two episodes of cold current occurred during the study period, and some mice died. The survival rates were compared pairwise against the control. The IR-treated group had a significantly reduced relative risk (p = 0.013) when compared with the control group, while the heat-treated group did not show any significant reduction (p = 0.087). There was no significant difference in body temperatures of the three groups before and after the irradiation. IR irradiation resulted in a significantly higher survival rate for mice that were concurrently subjected to cold and a forced swimming test. This result may be beyond the thermal effect.

PubMed Central

2014-01-01

Background To evaluate the effect of drainage tube on prognosis after total knee arthroplasty (TKA) and explore an effective treatment with favorable prognosis. Methods In a prospective study, 18 patients with TKA for the first time were included and randomly divided into three groups, group A (no placement of drainage tube), group B (negative pressure drainage), and group C (4 h clamping drainage). Intraoperative and postoperative blood loss, operation time, and the drainage volume were recorded and analyzed. Arthrocele, ecchymosis, and range of motion (ROM) were examined postoperatively. The degree of pain was scored by Visual Analog Scale (VAS) after 6, 12, and 24 h of operation. The complications were examined and HSS (hospital for special surgery) knee score was taken during the follow-up period. Results There was no significant difference in operation time, total blood loss, intraoperative blood loss, and VAS score among three groups. Meanwhile, the hidden blood loss in group B was significantly decreased compared with group A (P = 0.0015). The postoperative drainage volume of group B was significantly increased compared with group C (P = 0.0002). No drainage increased the rate of arthrocele and ecchymosis. Compared with group A, ROM after 3 days of operation in groups B and C was significantly increased (P = 0.0357, P = 0.0372, respectively). During follow-up study, no deep infection or deep venous thrombosis was found. Conclusion After TKA, early clamping of the drainage tube reduced the bleeding loss without adverse effect on prognosis, which might be useful for clinical application in future. PMID:24755244

Background An increase in the number of dentists conducting tobacco-use cessation treatment is needed. The authors assessed the effects of high-intensity training (HIT) or low-intensity training (LIT) and reimbursement on general dentists’ tobacco-use–related attitudes and treatment behaviors. Methods The authors randomly selected 265 dentists in three states and assigned them to one of five groups: HIT workshop groups with and without tobacco-use cessation counseling reimbursement, LIT mailed self-study groups with and without reimbursement or a control group. Outcomes at follow-up were dentists’ self-reported tobacco-use–related attitudes and behaviors and patients’ reports of dentists’ behaviors. Results Significantly more dentists in the intervention groups reported having positive attitudes and behaviors at follow-up than did dentists in the control group. Dentists in the HIT groups, however, reported assessing patients’ willingness to quit and assisting them with the quitting process significantly more often than did dentists in the LIT groups. Significantly more patients of dentists in the intervention groups who used tobacco reported receiving advice and assistance from their dentists than did patients of dentists in the control group. Adding reimbursement to HIT or LIT conditions did not provide additional intervention effect. Conclusion Dentists trained by means of a workshop or self-study program used components of a recommended guideline more frequently and felt more positive toward tobacco-use cessation counseling than did dentists in the control group. Clinical Implications Although the workshop training was more successful than the self-study training, the latter’s reach among dentists could have a more significant public health impact. The effect of reimbursement needs further study. PMID:22653940

The aim of this randomized controlled trial was to compare the skeletal and dentoalveolar effects of the modified tandem appliance (MTA) vs the facemask (FM) with rapid maxillary expansion. Thirty-two patients, aged 7 to 9 years were recruited. Eligibility criteria included skeletal class III malocclusion that resulted from the retrusion of the maxilla. Randomization was accomplished to divide the sample into two equal groups to be treated with either MTA or FM. Lateral cephalometric radiographs were obtained before treatment and after 2 mm positive overjet was achieved. Intragroup comparisons were performed using paired-sample t-test, and intergroup comparisons were performed using two-sample t-test at the p ≤ 0.05 level. Thirty-two patients (16 in each group) were available for statistical analysis. The pretreatment variables of both groups were similar. Both treatment therapies showed similar significant increase in the SNA and ANB angles, accompanied by slight decrease in the SNB angle. The increase in the SN:GoMe angle, Bjork's sum, and the overjet were significantly greater in the FM group. The forward movement of upper dentition was similar in both groups. Although the lower incisors retrusion was significantly greater in the FM group than in the MTA group, the uprighting of the lower molars was significantly greater in the MTA group. Both appliances showed similar effects apart from less clockwise rotation of the mandible, less retrusion of the lower incisors, and greater uprighting of the lower molars in the MTA group. Both the MTA and the FM groups are effective in treating class III malocclusion. The MTA group is more efficient in controlling the clockwise rotation and gaining some space in the lower arch.

To evaluate the therapeutic effect of scalp electroacupuncture for mild cognitive impairment (MCI) in the early stage. Two hundred and thirty three MCI patients were randomly divided into three groups: the drug group, the scalp electroacupuncture group, and the syndrome differentiation group. For the scalp electroacupuncture group, the points of Baihui (DU 20), Sishecong (EX-HN1), Fengchi (GB 20), and Shenting (DU 24) were selected. For the syndrome differentiation group, specific acupoints were added on the basis of syndrome differentiation and according to the scale for the differentiation of syndromes in vascular dementia (SDSVD) beside the acupoints used in the scalp electroacupuncture group. For the drug group, nimodipine was orally administered. Each patient was treated for two courses, eight weeks. The score differences in mini-mental state examination (MMSE), picture recognition, and clock drawing test were observed before and after the treatment. After treatment, the score differences in MMSE and clock drawing test were of obvious statistical significance among three groups (P < 0.01, P < 0.05). The score differences in picture recognition were of extremely statistical significance between the scalp electroacupuncture group and the syndrome differentiation group (P < 0.01), while the difference was not found in the drug group (P > 0.05). There were statistical significant differences in therapeutic effects between the scalp electroacupuncture group and the drug group, and between the syndrome differentiation group and the drug group (P < 0.05), while no statistical difference was found between scalp electroacupuncture group and the syndrome differentiation group (P > 0.05). All the three therapies may improve the cognitive function of MCI patients. The therapeutic effects in the scalp electroacupuncture and syndrome differentiation groups were basically the same, but superior to nimodipine.

Stinging nettle (Urtica dioica L.,) is a medicinal herb commonly used by humans. The role of reactive oxygen metabolites on cancer etiology is known. There are some studies about the antioxidant effects of Urtica Dioica (UD) on therapy of some cancer types. This study aimed to investigate the effects of UD on antioxidant enzyme activities and mammary gland cancer induced by in rats-N-methyl-N-nitrosourea (NMU) carcinogenesis. Rats were divided into four groups: a untreated group (Group 1), a NMU group (Group 2) given 50 mg/kg NMU by intraperitoneal (i.p.) injection, a NMU group (Group 3) treated with UD, a control group (Group 4) fed with 50g/kg UD. After 5.5 months, rats were decapitated, and mammary tissue and blood samples were obtained. There was a significant (p<0.05, p<0.01, respectively) increase in plasma malondialdehyde (MDA) levels of group 2 compared with group 1 and 4. The superoxide dismutase (SOD) activity of the erythrocytes was decreased in group 3 than the other groups (p<0.0001). The erythrocyte catalase (CAT) activity was significantly increased in group 4 compared with group 2 and 3 (p<0.05, p<0.01, respectively). The number of animals with palpable tumors was 6 (46.15%) in group 2, and 2 (13.3%) in group 3 at the end of the 22nd week. Although group 3 had lower palpable tumor number than group 2, the difference was not statistically significant (p=0.096). The results showed that UD constituents may have effects on lipid peroxidation and some antioxidant enzyme activities, and may slow the formation of mammary tumor. PMID:29844787

Objectives. The aim of this study was to explore effect of a combination of pregabalin and dexamethasone on pain control after septoplasty operations. Methods. In this study, 90 patients who were scheduled for septoplasty under general anesthesia were randomly assigned into groups that received either placebo (Group C), pregabalin (Group P), or pregabalin and dexamethasone (Group PD). Preoperatively, patients received either pregabalin 300 mg one hour before surgery, dexamethasone 8 mg intravenously during induction, or placebo according to their allocation. Postoperative pain treatment included tramadol and diclofenac sodium 30 minutes before the end of the operation. Numeric rating scale (NRS) for pain assessment, side effects, and consumption of tramadol, pethidine, and ondansetron were recorded. Results. The median NRS score at the postoperative 0 and the 2nd h was significantly higher in Group C than in Group P and Group PD (P ≤ 0.004 for both). The 24 h tramadol and pethidine, consumptions were significantly reduced in Groups P and PD compared to Group C (P < 0.001 and P < 0.001). The incidence of blurred vision was significantly higher in Group PD compared to Group C within both 0–2 h and 0–24 h periods (P = 0.002 and P < 0.001, resp.). Conclusions. We conclude that administration of 300 mg pregabalin preoperatively may be an adequate choice for pain control after septoplasty. Addition of dexamethasone does not significantly reduce pain in these patients. PMID:24876957

Background: This study aimed to compare the effects of the schema along with mindfulness-based therapies in the psoriasis patients. Materials and Methods: This semi-experimental study with post- and pre-tests was conducted on the psoriasis patients in the Dermatology Clinic of the Isfahan Alzahra Hospital, Iran using the convenience sampling in 2014. The patients had a low general health score. The experimental groups included two treatment groups of schema-based (n = 8) and mindfulness (n = 8). Both groups received eight 90-min sessions therapy once a week; they were compared with 8 patients in the control group. To evaluate the psoriasis patients’ maladaptive schema, Young schema questionnaire was used. Data were analyzed through the covariance analysis test. Results: There was a significant difference between the schema-based therapy and mindfulness groups with the control group. There was also a significant difference between the schema-based therapy groups consisting of the defeated schema, dependence/incompetence schema, devotion schema, stubbornly criteria schema, merit schema, restraint/inadequate self-discipline schema, and the control group. Moreover, a significant difference existed between the maladaptive schema of mindfulness therapy group and the controls. There was a significant difference concerning the improvement of the psychopathologic symptoms between the mindfulness therapy group and the control group. Conclusions: This study showed similar effects of both the schema and mindfulness-based therapies on the maladaptive schemas in improving the psoriasis patients with the psychopathologic symptoms.

To evaluate the effect of abducens orthosis combined with walker on developmental dysplasia of the hip (DDH). A total of 126 patients (224 hips) with DDH aged 6-36 months in Xiangya Hospital was randomly divided into 2 groups: an orthosis combined with walker group and an improved hip frog cast fixation group. Seventy patients (130 hips) were treated by the orthosis combined with walker and 56 patients (94 hips) were treated by the improved hip frog cast fixation. We compared the effect and complications of the 2 groups. The fineness rates of the orthosis combined with walker group and the improved hip frog cast fixation group were 89.2% and 90.4%, respectively, with no significant difference (P>0.05). The rate of femoral head osteonecrosis in the orthosis combined with walker group was significantly lower than that in the improved hip frog cast fixation group (1.5% vs. 5.3%,P<0.05), but the re-dislocation rate in the former was significantly higher than that in the latter (6.9% vs. 1.1 %, P<0.05). Both methods are effective for DDH. Orthosis combined with walker has a lower proportion of femoral head osteonecrosis, but a higher proportion of re-dislocation.

China has entered the aging society, but the social support systems for the elderly are underdeveloped, which may make the elderly feel anxiety about their health and life quality. Given the prevalence of generalized anxiety disorder (GAD) in the elderly, it is very important to pay more attention to the treatment for old adults. Although cognitive behavioral therapy targeting intolerance of uncertainty (CBT-IU) has been applied to different groups of patients with GAD, few studies have been performed to date. In addition, the effects of CBT-IU are not well understood, especially when applied to older adults with GAD. Sixty-three Chinese older adults with a principal diagnosis of GAD were enrolled. Of these, 32 were randomized to receive group CBT-IU (intervention group) and 31 were untreated (control group). GAD and related symptoms were assessed using the Penn State Worry Questionnaire, Intolerance of Uncertainty Scale-Chinese Version, Beck Anxiety Inventory, Beck Depression Inventory, Why Worry-II scale, Cognitive Avoidance Questionnaire, Generalized Anxiety Disorder Questionnaire-IV, and Generalized Anxiety Disorder Severity Scale across the intervention. The changes between pre and after the intervention were collected, as well as the six-month follow-up. F test and repeated-measures ANOVA were conducted to analyze the data. Compared to control group, the measures' scores of experimental group decreased significantly after the intervention and six-month follow-up. Besides the main effects for time and group were significant, the interaction effect for group × time was also significant. These results indicated the improvement of the CBT-IU group and the persistence of effect after six months. Group CBT-IU is effective in Chinese older adults with GAD. The effects of CBT-IU on GAD symptoms persist for at least six months after treatment.

The purpose of this study was to investigate the effects of two types of rehabilitation techniques, including aerobic and strengthening exercises on patients with knee rheumatoid arthritis (RA). 48 male patients with knee RA were randomly assigned into 3 groups, including aerobic exercises, strengthening exercise, and control. The two first groups completed their treatment protocol for 8 weeks, 3 days per week. Visual Analogue Scale, WOMAC questionnaire, 6-minute walking test, standard goniometer were used to assess pain severity, functional ability, walking ability, knee joint ROM respectively at baseline and after applying therapeutic interventions. The data were analyzed using one-way analysis of variance (ANOVA) at P < 0.05 significant level. Participants had a mean ± SD age of 58.6 ± 7.8 years (height 1.72 ± 0.07 m, weight 81.0 ± 6.4 kg) with no significant difference between three groups. Both therapeutic interventions reduced pain significantly (P < 0.001) compared to the control group, without significant difference between the two experimental groups. The patients fulfilled aerobic exercise attained higher levels of function and walking ability compared to strengthening group significantly (P < 0.001). The knee range of motion (ROM)wassignificantly (P < 0.001) improved in the two experimental groups in comparison to controls, the strengthening group had more significant (P < 0.001) improvement. It can be concluded that an aerobic exercise program improves functional and walking ability in patients with knee RA, and strengthening exercise has more efficient effect on knee ROM, both aerobic and strengthening exercises can equally relieve pain.

Background. This study evaluated the effect of two prophylaxis techniques on the marginal gap of CI V resin-modified glass-ionomer restorations. Methods. Standard Cl V cavities were prepared on the buccal surfaces of 48 sound bovine mandibular incisors in this in vitro study. After restoration of the cavities with GC Fuji II LC resin-modified glass-ionomer, the samples were randomly assigned to 3 groups of 16. In group 1, the prophylactic procedures were carried out with rubber cup and pumice powder and in group 2 with air-powder polishing device (APD). In group 3 (control), the samples did not undergo any prophylactic procedures. Then the marginal gaps were measured. Two-way ANOVA was used to compare marginal gaps at the occlusal and gingival margins between the groups. Post hoc Tukey test was used for two-by-two comparisons. Statistical significance was set at P < 0.05. Results. There were significant differences in the means of marginal gaps in terms of prophylactic techniques (P < 0.001), with significantly larger marginal gaps in the APD group compared to the pumice and rubber cup group, which in turn exhibited significantly larger marginal gaps compared to the control group (P < 0.0005). In addition, the means of marginal gaps were significant in terms of the margin type (P < 0.001), with significantly larger gaps at gingival margins compared to the occlusal margins (P < 0.0005). Conclusion. The prophylactic techniques used in this study had a negative effect on the marginal gaps of Cl V resin-modified glass-ionomer restorations.

To investigate the short-term effects of a lifestyle modification intervention based on a mobile application (app) linked to a hospital electronic medical record (EMR) system on weight reduction and obstructive sleep apnea (OSA). We prospectively enrolled adults (aged >20 years) with witnessed snoring or sleep apnea from a sleep clinic. The patients were randomized into the app user (n=24) and control (n=23) groups. The mobile app was designed to collect daily lifestyle data by wearing a wrist activity tracker and reporting dietary intake. A summary of the lifestyle data was displayed on the hospital EMR and was reviewed. In the control group, the lifestyle modification was performed as per usual practice. All participants underwent peripheral arterial tonometry (WatchPAT) and body mass index (BMI) measurements at baseline and after 4 weeks of follow-up. Age and BMI did not differ significantly between the two groups. While we observed a significant decrease in the BMI of both groups, the decrease was greater in the app user group (P <0.001). Apnea-hypopnea index, respiratory distress index, and oxygenation distress index did not change significantly in both groups. However, the proportion of sleep spent snoring at >45 dB was significantly improved in the app user group alone (P =0.014). In either group, among the participants with successful weight reduction, the apnea-hypopnea index was significantly reduced after 4 weeks (P =0.015). Multiple regression analyses showed that a reduction in the apnea-hypopnea index was significantly associated with BMI. Although a short-term lifestyle modification approach using a mobile app was more effective in achieving weight reduction, improvement in OSA was not so significant. Long-term efficacy of this mobile app should be evaluated in the future studies.

Creatine monohydrate has beneficial effects on serum glucose. This study aimed to investigate the effects of creatine on serum biochemical markers and permeability of coronary arteries among diabetic rats. 32 Wistar rats, which weighed 150-200 grams were randomly divided into 4 groups including: group I, control; group II, creatine monohydrate; group III, diabetic rats; and group IV, diabetic rats + creatine. Creatine monohydrate was applied by 400 mg/kg/daily for 5 months. Animals' weights and blood samples were taken before and after the study. Endothelial permeability rate was measured by Evans Blue method. Data were analysed by SPSS 16. At the end of fifth month, rats' weights in diabetic group under treatment with creatine, compared to those without, increased significantly (p<0.0001). Also, the serum levels of triglyceride (TG), cholesterol, glucose and low density lipoprotein (LDL)- cholesterol decreased significantly among those under treatment with creatine (p<0.05), but high density lipoprotein (HDL)- cholesterol increased significantly (p<0.002). Permeability rate of coronary arteries was reduced significantly in the diabetic group treated by creatine compared to untreated groups, closed to the intact group (p<0.001). Results of this study showed that creatine monohydrate caused an improvement of serum biochemical markers associated with diabetes and reduced the permeability rate of coronary arteries among diabetic rats. © 2016 by the Association of Clinical Scientists, Inc.

To investigate the effect of silica coating by sol-gel process on bonding strength of zirconia ceramics to dentin. Blocks of sintered zirconia ceramics were cut and randomly divided into 4 groups,16 slices in each group. Each group was subject to one of the 4 kinds of surface treatment (control group, sandblasting, sandblasting +silicone, sandblasting + silica coating + silicone) and then bonded to dentin with resin cement. After preservation in 37 degrees centigrade distilled water for 24 hours, the shear bonding strength of these specimens was tested and the data was analyzed with SAS6.12 software package for analysis of variance. The surface modality of the ceramics was observed under scanning electron microscopy (SEM). The group of sandblasting+ silica coating + silicone attained the highest shear bonding strength, which was significantly different from the other groups(P=0.000);There was no significant difference between the sandblasting and sandblasting + silicone group (P=0.827), which was significantly different from the control group(P=0.001). Silica coating by sol-gel process, coupled with silicone, can significantly increase the bonding strength of zirconia ceramics to dentin.

Ghrelin is an orexigenic peptide which is secreted from stomach. Cannabis sativa is known as an orexigenic herb in Iranian traditional medicine. Little evidence is published about its effect on energy intake and its mechanism. In the current study, the possible effect of hydroalcoholic extract of C. sativa on appetite and ghrelin is evaluated. Thirty male Wistar rats were randomly divided into five groups. Two control groups were selected, the first group received 0.5 mL water per day (vehicle group) and another group did not receive anything (control group). The other three groups were treated daily with 50, 100 or 150 mg/kg of C. sativa for 7 days, respectively. Daily energy intake of the rats was calculated for 10 days prior to the> intervention and for the 7 day intervention. To investigate changes in plasma ghrelin as a potential mechanism, an orexigenic dose (150 mg/kg) of C. sativa or distilled water (vehicle) was fed to two separate groups of six rats by gavage. Total ghrelin levels in plasma were measured for 3 h post-gavage. There was no significant difference in energy intake between control and vehicle groups. Treatment with 100 and 150 mg/kg of the extract significantly increased energy intake vs the other groups (p<0.05). Total ghrelin levels were significantly elevated in the C. sativa group vs vehicle 30 and 60 min post-gavage. This study showed that C. sativa had both positive and dose-related effects on appetite of rats. Future studies are warranted to evaluate the orexigenic effect of this plant in human.

Melatonin has been considered a potent antioxidant that detoxifies a variety of reactive oxygen species in many pathophysiological states of eye. The present study was designed to determine the effects of Wi-Fi exposure on the lens oxidant, antioxidant redox systems, as well as the possible protective effects of melatonin on the lens injury induced by electromagnetic radiation (EMR). Thirty-two rats were used in the current study and they were randomly divided into four equal groups as follows: First and second groups were cage-control and sham-control rats. Rats in third group were exposed to Wi-Fi (2.45 GHz) for duration of 60 min/day for 30 days. As in the third group, the fourth group was treated with melatonin. The one-hour exposure to irradiation in second, third and fourth took place at noon each day. Lipid peroxidation levels in the lens were slightly higher in third (Wi-Fi) group than in cage and sham control groups although their concentrations were significantly (P < 0.05) decreased by melatonin supplementation. Glutathione peroxidase (GSH-Px) activity was significantly (P < 0.05) lower in Wi-Fi group than in cage and sham control groups although GSH-Px (P < 0.01) and reduced glutathione (P < 0.05) values were significantly higher in Wi-Fi + melatonin group than in Wi-Fi group. There are poor oxidative toxic effects of one hour of Wi-Fi exposure on the lens in the animals. However, melatonin supplementation in the lens seems to have protective effects on the oxidant system by modulation of GSH-Px activity.

Infertility issues have been linked to the effect of oxidative reaction in the reproductive system. This study evaluated the effect of ascorbic acid, on fertility parameters of male albino Wistar rats was studied. Eighteen albino Wistar rats weighed between 178 g and 241 g were used, randomly assigned into three groups. Group 1 was the control group; oral gavaged 5 ml of distilled water; Groups 2 and 3 were administered medium dose (250 mg/kg) and high dose of ascorbic acid (400 mg/kg), respectively; twice daily for 21 days. Blood samples were obtained by cardiac puncture, and blood serum was obtained for hormonal assay, and the testes were harvested for sperm analysis. Follicle stimulating hormone levels significantly increased in the high-dose group as compared to both the control and medium dose groups. Luteinizing hormone levels in the medium dose group decreased significantly as compared to the control group. Testosterone significantly increased in both the medium- and high-dose groups as compared to the control group. Sperm motility increased significantly in the high-dose group as compared to both control and medium-dose groups. Percentage sperm concentration decreased significantly in the medium-dose group when compared to the control and increased significantly in the high-dose group as compared to the medium-dose group. For percentage normal morphology, there was a dose-dependent increase in the test groups when compared to control group. These results are indicative of a positive influence of ascorbic acid on male fertility modulators and may therefore, serve as a potential adjuvant treatment for male infertility cases.

Background There is evidence for an adaptive role of the omega -3 fatty acid, docosahexaenoic acid (DHA) during stress. Mechanisms of action may involve regulation of stress mediators, such as the catecholamines and proinflammatory cytokines. Prevention of stress-induced aggression and hostility were demonstrated in a series of clinical trials. This study investigates whether perceived stress is ameliorated by DHA in stressed university staff. Methods Subjects that scored ≥ 17 on the Perceived Stress Scale were randomised into a 6-week pilot intervention study. The diet reactive group was supplemented with 6 g of fish oil containing 1.5 g per day DHA, while the placebo group was supplemented with 6 g a day of olive oil. The groups were compared with each other and a wider cross sectional study population that did not receive either active or placebo intervention. Results There was a significant reduction in perceived stress in both the fish oil and the placebo group from baseline. There was also a significant between-group difference between the fish oil group and the no-treatment controls in the rate of stress reduction (p < 0.05). However, there was not a significant between-group difference between the fish oil and the placebo group, nor the placebo group and the control group. These results are discussed in the context of several methodological limitations. The significant stress reductions in both the fish oil and the placebo group are considered in view of statistical regression, an effect likely to have been exaggerated by the time course of the study, a large placebo effect and the possibility of an active effect from the placebo. Conclusion There were significant differences (p < 0.05) in the fish oil group compared with no-treatment controls. This effect was not demonstrated in the placebo group. As a pilot study, it was not sufficiently powered to find the difference between the fish oil group and the placebo group significant. Further work needs to be undertaken to conclusively demonstrate these data trends. However, the findings from this research support the literature in finding a protective or 'adaptogenic' role for omega-3 fatty acids in stress. PMID:15566625

This study was designed to evaluate the inhibitory effect of nimesulide in combination with oxaliplatin on tumor growth, expression of COX-2, VEGF-C, VEGFR-3, survivin and β-catenin, and lymphatic metastasis in lung cancer xenograft in nude mice, and to discuss the possible synergistic effect of nimesulide in combination with oxaliplatin. Human lung cancer A549 cells were injected into BALB/c nude mice subcutaneously. Thirty-three healthy male nude mice were randomly divided into 4 groups: the control group, nimesulide group, oxaliplatin group and nimesulide combined with oxaliplatin group. Transplanted tumor tissues were collected and the expressions of COX-2, VEGF-C, VEGFR-3, survivin, β-catenin protein were detected by immunohistochemistry, and RT-PCR assay was used to assess the expression of tumor COX-2, VEGF-C, VEGFR-3, survivin and β-catenin mRNA. SPSS 16.0 was used for statistical analysis. Data were present as (x(-) ± s), and the means were compared by analysis of variance test. Tumor inhibition rates of the nimesulide group, oxaliplatin group and nimesulide + oxaliplatin group were 39.73%, 48.04% and 65.94%, respectively. Immunohistochemical and RT-PCR analysis showed that compared with the control group, the expression levels of COX-2, VEGF-C, VEGFR-3, survivin and β-catenin of the nimesulide group were significantly reduced (all P < 0.05). Compared with the control group, statistical analysis of variance showed that the expression levels of COX-2, VEGF-C and VEGFR-3 of the oxaliplatin group were significantly increased (P < 0.05), the expression levels of survivin and β-catenin protein and mRNA of the oxaliplatin group were significantly reduced (P < 0.05). Compared with the control group, the expression levels of COX-2, VEGF-C, VEGFR-3, survivin and β-catenin of the nimesulide + oxaliplatin group were significantly reduced (all P < 0.05). Both nimesulide alone or in combination with oxaliplatin can significantly inhibit the growth of lung cancer xenografts in nude mice and the expression levels of COX-2, VEGF-C, VEGFR-3, survivin and β-catenin. Oxaliplatin can significantly inhibit the growth of lung cancer xenografts in nude mice, and the expression of survivin and β-catenin. Nimesulide in combination with oxaliplatin enhances the antitumor effect of oxaliplatin.

The present study was conducted to determine the effect of massage on post-cesarean pain and anxiety. The present single-blind clinical trial was conducted on 156 primiparous women undergone elective cesarean section. The participants were randomly divided into three groups, including a hand and foot massage group, a foot massage group and a control group (n = 52 per group). The patients' intensity of pain, vital signs and anxiety level were measured before, immediately after and 90 min after the massage. A significant reduction was observed in the intensity of pain immediately and 90 min after massage (P < 0.001). Moreover, changes in some of the physiological parameters, including blood pressure and respiration rate, were significant after massage (P < 0.001); however, this change was not significant for pulse rate. A significant reduction was also observed in the level of anxiety (P < 0.001) and a significant increase in the frequency of breastfeeding (P < 0.001) after massage. As an effective nursing intervention presenting no side-effects, hand and foot massage can be helpful in the management of postoperative pain and stress. Copyright © 2016 Elsevier Ltd.

Purpose To assess the effect of extracorporeal shock wave therapy (ESWT) for healthy participants with hamstring tightness. Materials and Methods This study was performed at a university rehabilitation hospital. Twenty nine healthy adults with hamstring tightness were enrolled and randomly allocated into four groups (ESWT, stretching exercise, ESWT with stretching exercise, and control). The effects of individual treatments were compared by the finger-to-floor test and popliteal angle. Results The ESWT group, stretching exercise group and ESWT with stretching exercise group had decreased finger-to-floor distances and right popliteal angles immediately after intervention, compared with the control group (p<0.05). At 4 weeks after completion of the interventions, finger-to-floor distances and the right popliteal angle in only the ESWT with stretching exercise group showed a significant improvement, compared with the control group (p=0.008 and 0.023). Conclusion While ESWT and stretching both reduced hamstring tightness immediately after interventions, only ESWT with stretching exercise maintained the significantly improved relief of hamstring tightness significantly after 4 weeks.

To evaluate the effect of Fe2O3 and CeO2 as colorants on yttria stabilized tetragonal zirconia poly-crystals (Y-TZP) powder. The spray granulation slurry of colored zirconia was prepared with different concentrations of Fe2O3 (0.15%) and CeO2 (4%), which were added in Y-TZP. Zirconia powder was made by spray granulation. The powder specimens were divided into three groups: uncolored zirconia, Fe2O3 (0.15%) zirconia, and CeO2 (4%) zirconia. The particle morphologies of the powder specimens were measured with a laser particle size analyzer and an optical microscope. The differences in D50 among the three groups were statistically significant (P<0.05). Group Fe2O3 showed a significant difference from groups CeO2 and uncolored zirconia (P<0.05). Group uncolored zirconia showed no significant difference from group CeO2 (P>0.05). Mostly spherical powder was observed in the three groups. Fe2O3 as a colorant can affect particles, whereas CeO2 has no effect.

2012-01-01

The birth date distributions of elite male and female footballers in Australia, from junior youth (age 14 and upwards) to senior (professional) players, were examined. A statistically significant relative age effect was found among junior male players, reducing in effect with increasing age. An inter-year relative age effect that became apparent among the players at national level in the Under-17 and Under-20 age groups, due to the timing of the respective World Cups for those age groups, was also identified. It is conjectured that this might lead to players born in certain years having a curtailed pathway in the elite game, leading to drop-out among this very elite group. In the case of women elite players, no significant relative age effect was found among youth players, possibly due to less fierce competition for places, although a significant effect was found to exist at senior elite level.

In tackling the ongoing malnutrition problem in many parts of Kenya, the government has initialized preventive actions such as mother support groups in order to improve health and nutrition among children. Few studies have evaluated the effectiveness of such intervention. This study aimed at determining how mother support groups affect the nutrition status of children under 2 years of age. 41 children participated. Anthropometric measurements were taken of the children once a month during 12 months. Medical history, nutrition status and socioeconomic factors were collected by interviews with the mothers. The children were divided into two groups depending on their mother's assigned group; mother support group or not. Nutritional status was significantly better among children in the mother support group (P=0.001). There were significantly more children with severe acute malnutrition among the children not in support group (P=0.040). The mean height (P=0.001) and mean weight (P=0.0281) were significantly higher among children in the non-support group. Mother support groups may have a beneficial effect on the nutritional status of children under 2 years of age. Cases of severe acute malnutrition seemed to be less prevalent in children whose mothers attend mother support groups.

The aim of this study was to investigate effects of Clinical Pilates Exercises on bone mineral density (BMD), physical performance and quality of life (QOL) in postmenopausal osteoporosis. Forty-one women were recruited to the study. The subjects were divided into two groups, as the Pilates group and the control group. Subjects were evaluated for BMD at the lumbar region. Physical performance level was measured. Pain intensity level was scored with Visual Analogue Scale. QUALEFFO-41 was used for assessing QOL. BMD values increased in the Pilates group (p < 0.05), while BMD decreased in the control group (p< 0.05). Physical performance test results showed significant increases in the Pilates group (p< 0.05) whereas there was no changes in the control group (p> 0.05). Pain intensity level in the Pilates group was significantly decreased after the exercise (p< 0.05), while it was unchanged in the control group. There were significant increases in all parameters of QOL in the Pilates group. Conversely, some parameters of QOL showed decreases in the control group (p< 0.05). Pilates Exercises is effective to increase BMD; QOL and walking distance and also beneficial to relieve pain. Physiotherapist can use Pilates Exercises for the subjects with osteoporosis in the clinics.

Objectives: Punica granatum L., (Family: Punicaceae) is used in Indian Unani medicine for treatment of diabetes mellitus. Therefore, the present study was done to evaluate the antidiabetic and antihyperlipidemic effects of ethanolic extract of leaves of P. granatum in alloxan-induced diabetic rats. Materials and Methods: Healthy Wistar albino rats (100-150 g) were divided into four groups of six animals each. Groups A and B received normal saline [(10 ml/kg/day/per oral (p.o.)]; group C received ethanolic extract of leaves of P. granatum (500 mg/kg/p.o.); and group D received glibenclamide (0.5 mg/kg/day/p.o.). The extracts were given for 1 week in all groups. To induce diabetes, alloxan 150 mg/kg, intraperitoneal (i.p.) single dose was administered to groups B, C, and D. Blood glucose and serum lipids [Total Cholesterol (TC), Triglycerides (TG), Low Density Lipoproteins (LDL), and High Density Lipoproteins (HDL)] and the atherogenic index were estimated after one week. For mechanism of antidiabetic action glycogen estimation on the liver, cardiac and skeletal muscle, and intestinal glucose absorption was done. Results: Group B showed a significant (P<0.01) increase in blood glucose as compared to group A. Groups C and D showed significant decrease (P<0.01) in blood glucose level in comparison to group B. The test drug showed a significant (P<0.01) increase in glycogen content in the liver, cardiac, and skeletal muscle; it significantly (P<0.01) reduced intestinal glucose absorption. Groups C and D showed significant (P<0.01) decrease in serum TC, TG, LDL, and AI as compared to Group B, which showed a significant (P<0.01) increase. Groups C and D showed significant (P<0.01) increase in serum HDL as compared to Group B, which showed a significant (P<0.01) decrease in all values. Conclusion: P. granatum leaves possess significant antidiabetic and antihyperlipidemic activity. PMID:22529479

The purpose of this study was to investigate the therapeutic effects of small hairpin RNA (shRNA) targeting endothelin-converting enzyme (ECE)-1 in monocrotaline (MCT)-induced pulmonary hypertensive rats. Ninty-four Sprague-Dawley rats were divided into three groups: control (n = 24), MCT (n = 35) and shRNA (n = 35). Four-week survival rate in the shRNA group was significantly increased compared to that in the MCT group. The shRNA group showed a significant improvement of right ventricular (RV) pressure compared with the MCT group. The MCT and shRNA groups also showed an increase in RV/(left ventricle + septum) ratio and lung/body weight. Plasma endothelin (ET)-1 concentrations in the shRNA group were lower than those in the MCT group. Medial wall thickness of pulmonary arterioles were increased after MCT injection and was significantly decreased in the shRNA group. The number of intra-acinar muscular pulmonary arteries was decreased in the shRNA group. The mRNA expressions of ET-1 and ET receptor A (ET(A)) were significantly decreased in the shRNA group in week 4. The protein levels of ET(A) were decreased in the shRNA group in week 2. The protein levels of tumor necrosis factor-α and vascular endothelial growth factor were decreased in the shRNA group in week 4. In conclusion, the gene silencing with lentiviral vector targeting ECE-1 could be effective against hemodynamic, histopathological and gene expression changes in pulmonary hypertension.

To explore the effects on thyroid function in patients of Hashimoto's thyroiditis treated with aconite cake-separated moxibustion and option the better therapeutic program. Eighty-five cases were randomly divided into a moxibustion group (42 cases) and a western medication group (43 cases). The moxibustion group was treated by aconite cake-separated moxibustion therapy with acupoints of two groups [(1) Danzhong (CV 17), Zhongwan (CV 12), Guanyuan (CV 4); (2) Dazhui (GV 14), Shenshu (BL 23), Mingmen (GV 4)] alternatively and oral administration of 25 microg Euthyrox everyday. The western medication group was oral administration of 25 microg Euthyrox everyday. Indices of thyroid function before and after treatment and clinical effect were compared between two groups. The clinical total effective rate and effective rate of thyroid function were 25.0% (10/40), 87.5% (35/40) in moxibustion group respectively, 7.53% (3/40) and 57.5% (23/40) in western medication group, with significant differences between two groups (both P < 0.05). Content of serum free thyroxine index (FT4) increased significantly in the moxibustion group after treatment (P < 0.01); content of serum supersensitive thyrotropin (S-TSH) in the moxibustion group was lower than that of western medication group, and contents of serum FT4 and free triiodothyronine (FT3) were higher than those of western medication group, but with no significant differences (all P > 0.05). Aconite cake-separated moxibustion at Guanyuan (CV 4) and Mingmen (GV 4) combined with oral administration of Euthyrox can improve clinical symptoms and thyroid function in patients of Hashimoto's thyroiditis, which is better than simple oral administration of Euthyrox.

Forty-five patients with class IV cardiac function were divided into three groups: group I (digoxin group), group II (Red Ginseng group) and group III (Red Ginseng plus digoxin group). Each group consisted of 15 cases. After treatment, the improvement of the hemodynamical and biochemical indexes of group II and group III were greater than those of group I, and group III was the most significant amongst all. The results suggested that Red Ginseng and digoxin had synergism for treatment of congestive heart failure, and Red Ginseng was an effective and safe adjuvant without any side effects.

To analysis the effects of Talpha1 on the immune effector molecules in mouse immune system. Sixty five BABL/c mice were divided into four groups: CsA group (n=20), Talpha1 group (n= 20), CsA+Talpha1 group (n=20) and control group (n=5). In the 3 experimental groups, 10 mg/kg CsA, 400 microg/ kg Talpha1, 10 mg/kg CsA+400 microg/kg Talpha1 were respectively administrated by intraperitoneal injection daily. Luminex was performed for cytokine detection at 1 d, 7 d, 14 d, 21 d day after the above treatments. Lymphocyte culture was prepared with the mouse spleen suspension, and then treated with 0. 25 mg/mL CsA, 10 microg/mL Talpha1 or 0.25 mg/mL CsA+10 microg/mL Talpha1 in vitro, respectively. Three days later, OD values of each treated lymphocyte culture and several cytokines in the culture were measured. Compared with other groups, CsA+Talpha1 group had significant lower IL-1alpha, IL-2, IL-6, IL-17, and significant higher IL-10 at 1 d, 7 d, 14 d, 21 d after the treatments (P < 0.05). Three days after the culture, OD value in the control group was significantly higher than that in Talppha1 group, CsA group, and CsA+ Talpha1 group (P < 0.05). IL-1alpa and IL-6 in the control group were significantly higher than those in the experiment groups (P < 0.05), while IL-10 in the control group was significantly lower than that in the experiment groups (P < 0.05). IL-2 and IL-17 were similar. Talpha1 show regulatory effect on the immune effector molecules which could promote Th1 cells transforming to Th2 cells.

The effect of nicotine on heart rate variability (HRV) is controversial. Autonomic nervous system is the main regulator of heart rhythm, and heart rate variability is an appropriate index to assessment of the effects of the autonomic system on heart. In this study, the combination effect of nicotine and black tea consumption on sympatho-vagal balance and heart rate variability was investigated in rats. Male Wistar rats were randomized into four groups as control, tea (2.5 g/100 cc, daily), nicotine (2 mg/kg/d) and tea plus nicotine groups which treated for 28 days, and in the 29th day, their electrocardiograms (lead II) were recorded. The mean of high-frequency power (HF) in tea, nicotine and tea plus nicotine groups was significantly more than control group (P < .05), and low-frequency power/high-frequency power (LF/HF) ratio in the nicotine and tea + nicotine groups was significantly less than control group (P < .05). LF values did not differ significantly among groups. Mean of standard deviation of normal RR intervals (SDNN) and square root of the mean squared differences of successive RR intervals (RMSSD) increased significantly in tea, nicotine and tea + nicotine groups in comparison with control group (P < .05) Overall, 4-week administration of black tea, nicotine or their combination with dosages used in this study can increase the heart rate variability and improve the sympatho-vagal balance in rat. © 2017 John Wiley & Sons Ltd.

Both repaglinide and gliclazide are insulin secretagogues widely used in the treatment of type 2 diabetes. They stimulate insulin secretion through distinct mechanisms and may benefit patients from different aspects. The present study was to evaluate the effects of repaglinide or gliclazide on glycaemic control, insulin secretion, and lipid profiles in type 2 diabetes patients. A total of 47 newly diagnosed type 2 diabetes patients were randomized 1:1 to receive a 4-week treatment with repaglinide or gliclazide. The standard mixed meal tolerance test was performed before and after the treatment. Plasma glucose (PG), insulin concentration, and lipid profiles were measured. The area under insulin concentration curve (AUC(ins)) and the early-phase insulin secretion index (ΔI(30)/ΔG(30)) were calculated. After the trial, fasting and postprandial PG and postprandial insulin improved significantly in both groups (P < 0.05). The maximum insulin concentration occurred earlier in the repaglinide group than that in the gliclazide group. AUC(ins) increased in both groups (P < 0.05), but no significant difference was found between groups. ΔI(30)/ΔG(30) increased in both groups (P < 0.05), especially in the repaglinide group (P < 0.05). Triglyceride and total cholesterol decreased significantly in the repaglinide group in some time points, while no significant change was observed in the gliclazide group. Repaglinide and gliclazide had similar effects on glycaemic control and total insulin secretion, while repaglinide had more effects on improvements in β-cell function and lipid metabolism.

The aim of our study was to determine the effectiveness of intratympanic α-lipoic acid injection as an otoprotective agent against cisplatin-induced ototoxicity in guinea pigs. Twenty-four adult male albino guinea pigs with normal hearing were divided into 4 groups. The guinea pigs received intraperitoneal cisplatin in group 1, intraperitoneal cisplatin and intratympanic α-lipoic acid in group 2, intratympanic α-lipoic acid in group 3, as well as intraperitoneal cisplatin and intratympanic saline in group 4. Distortion-product otoacoustic emission measurements were obtained for both ears at the following time points: before administration (baseline recording) and on day 3 (72 h later). In group 1 (cisplatin), significant deterioration was observed at all frequencies on day 3 (P < 0.05). In group 2 (cisplatin + α-lipoic acid), deterioration was observed at all frequencies on day 3; however, this deterioration did not reach a statistical significance (P > 0.05). In group 3 (α-lipoic acid), no significant difference was observed between baseline and day 3 (P > 0.05). In group 4 (cisplatin + saline), deterioration was observed at all frequencies on day 3; however, this deterioration did not reach a statistical significance (P > 0.05). Cisplatin-induced hearing loss in the guinea pigs may be limited to some extent by the concomitant use of α-lipoic acid. Dose-dependent changes in the possible effects of α-lipoic acid need further investigation. Future morphologic studies may contribute to expose clearly the protective effect of α-lipoic acid.

The present study was performed to investigate the effect of astaxanthin in combination with other antioxidants against oxidative damage in streptozotocin (STZ)-induced diabetic Osteogenic Disorder Shionogi (ODS) rats. Diabetic-ODS rats were divided into five groups: control, astaxanthin, ascorbic acid, alpha-tocopherol, and tocotrienol. Each of the four experimental groups was administered a diet containing astaxanthin (0.1 g/kg), in combination with ascorbic acid (3.0 g/kg), alpha-tocopherol (0.1 g/kg), or tocotrienol (0.1 g/kg) for 20 wk. The effects of astaxanthin with other antioxidants on lipid peroxidation, urinary 8-hydroxy-2-deoxyguanosine (8-OHdG) excretion, serum creatinine (Cr) level, creatinine clearance (Ccr), and urinary protein content were assessed. The serum lipid peroxide levels and chemiluminescent (CL) intensity in the liver of the alpha-tocopherol and tocotrienol groups were significantly reduced in comparison to that of the control group. In the alpha-tocopherol group, urinary 8-OHdG excretion, serum Cr level, Ccr, urinary albumin excretion, and urinary protein concentration were significantly decreased as compared with those in the control group. Additionally, the CL intensity in the kidney of the alpha-tocopherol group was significantly lower, but that of the ascorbic acid group was significantly higher than that in the control group. These results indicate that dietary astaxanthin in combination with alpha-tocopherol has an inhibitory effect on oxidative stress. On the other hand, our study suggests that excessive ascorbic acid intake increases lipid peroxidation in diabetic rats.

Cryptorchidism, a common anomaly of the male genitalia, affects 2-4% of male infants. The post-fertilization effects of unilateral cryptorchidism model in the rat and the effects of antioxidant treatment were investigated. Six-week-old male Wistar rats were randomly separated into four groups. Unilateral cryptorchidism was induced in the right testis of three groups. One group was treated with saline intraperitoneally (i.p.) (Crypto), one group was treated with taurine (500 mg/kg, i.p.; Tau), and another group was treated with sivelestat (15 mg/kg i.p.; Siv). The control group was treated with saline i.p. The treatment was daily for 8 weeks. Five days before sacrifice, mating studies were performed. Body, testicular, and epididymal weights were recorded. Malondialdehyde (MDA) levels in the seminal vesicular fluid (SVF) were measured. Testicular levels of MDA and 8-hydroxy-2'-deoxyguanosine (8-OHdG) were determined bilaterally. TUNEL assay was used to examine DNA fragmentation bilaterally. Histological examination and the Johnsen score were used to evaluate morphological testicular alterations. The Crypto group demonstrated significantly lower right testicular and epididymal weights, significantly increased SVF-MDA levels, testicular MDA and 8-OHdG levels, and the apoptotic score bilaterally compared to the controls. Furthermore, histological evaluation revealed significantly reduced spermatogenesis and mild injury to the cryptorchid testes compared to the control. Treatment with both taurine and sivelestat significantly reduced SVF-MDA levels, testicular MDA, 8-OHdG, and apoptosis bilaterally compared to the Crypto group. Antioxidant treatment was unable to ameliorate spermatogenesis. Newborns delivered by females that mated with Crypto-males had significantly lower body weight compared with the respective animals from the control, Tau and Siv groups. The present study demonstrated that unilateral cryptorchidism-induced testicular damage can significantly affect the contralateral testis as well having further deleterious post-fertilization effect on the development of newborns. Treatment with antioxidants can partially improve the testicular damage bilaterally with beneficial effects for the newborns. © 2016 American Society of Andrology and European Academy of Andrology.

Transcranial direct current stimulation (tDCS) is a noninvasive technique to modulate the neural membrane potential. Its effects in the early stage of traumatic brain injury (TBI) have rarely been investigated. This study assessed the effects of anodal tDCS on behavioral and spatial memory in a rat model of traumatic brain injury. Thirty six rats underwent lateral fluid percussion and were then randomly assigned to one of three groups: control (n=12), five-day tDCS over peri-lesional cortex at one (1W, n=12), or two (2W, n=12) weeks post-injury. The Barnes maze (BM) and Rotarod (RR) tests were evaluated in a blind manner on day 1, week 3 and week 5 post-injury. After three weeks, both the 1W and 2W groups showed significant improvements in the BM ratio (P<0.05), whereas only group 2W obtained a significant improvement in the RR ratio compared with the control group (P<0.05). However, there were no significant differences between any of the groups at five weeks after TBI. Immunohistochemistry revealed that only group 2W had a significantly higher brain-derived neurotrophic factor (BDNF) expression in the peri-lesional cortex, which was significantly correlated with the improvement of the Rotarod test at 3-week post-injury. However, BDNF expression in the ipsi-lesional hippocampus was not significantly different among the three groups. Group 1W tended to have increased choline/creatine ratios, as measured by magnetic resonance spectroscopy in the peri-lesional cortex, than the control group (P=0.051). Neither regimen aggravated the lesion volume or brain edema measured by MRI. These beneficial effects were not observed with either regimen at five weeks post-injury. In conclusions, anodal tDCS ameliorated behavioral and spatial memory function in the early phase after TBI when it is delivered two weeks post-injury. Earlier stimulation (one week post-injury) improves spatial memory only. However, the beneficial effects did not persist after cessation of the anodal stimulation. Copyright © 2016 Elsevier B.V.

This study sought to investigate the effects of hypothermia induced by adenosine 5'-monophosphate (5'-AMP) on L-arginine (L-Arg)-induced acute pancreatitis in rats. The rats were divided into four groups: the control group, the acute pancreatitis group, the 5'-AMP pretreatment group, and the 5'-AMP posttreatment group. Rats in all groups, except for the control group, received two injections of 2.5 g/kg body weight (intraperitoneally) L-Arg, with an interval of 1 h between the injections. Subsequently, the rats were observed to assess whether hypothermia induced by 5'-AMP could effectively inhibit inflammation associated with L-Arg-induced acute pancreatitis in rats. Hypothermia induced by 5'-AMP produced protective effects in our acute pancreatitis model. These effects exhibited the following manifestations: (i) a significant reduction in rat mortality rates; (ii) a significant decrease in the occurrence of pancreatic edema; (iii) significant reductions in serum amylase (P < 0.001), interleukin-6 (P < 0.001), interleukin-1β (P < 0.001) and tumor necrosis factor-α (P < 0.001); (iv) the significant inhibition of nuclear factor-κB (NF-κB) activation in rats that were pre- and posttreated with 5'-AMP compared with rats that were only injected with L-Arg; and (v) significant decreases in the occurrence of pancreatic interstitial edema, inflammatory cell infiltration, hemorrhage, and acinar cell necrosis. Hypothermia induced by 5'-AMP could inhibit the acute inflammatory reaction and NF-κB activation associated with acute pancreatitis. © 2013 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

Chromium treatment has been shown to improve glucose regulation in some populations. The purpose of this study was to evaluate whether chromium picolinate (CrPic) supplementation improves glucose regulation in overweight individuals with binge-eating disorder (BED). In this double-blinded randomized pilot trial, participants (N = 24) were randomized to high (HIGH, 1000 mcg/day, n = 8) or moderate (MOD, 600 mcg/day, n = 9) dose of CrPic or placebo (PL, n = 7) for 6 months. Participants completed an oral glucose tolerance test (OGTT) at baseline, 3 months, and 6 months. Fixed effects models were used to estimate mean change in glucose area under the curve (AUC), insulin AUC , and insulin sensitivity index (ISI). Results revealed a significant group and time interaction (p < 0.04) for glucose AUC , with glucose AUC increasing significantly in the PL group (p < 0.02) but decreasing significantly in the MOD group (p < 0.03) at 6 months. Insulin AUC increased significantly over time (main effect, p < 0.02), whereas ISI decreased significantly over time (main effect, p < 0.03). As anticipated, a moderate dose of CrPic was associated with improved glycemic control, whereas PL was associated with decreased glycemic control. It was unexpected that the improved glycemic control seen in the MOD dose group was not seen in the HIGH dose group. However, although participants randomized to the HIGH dose group did not have improved glycemic control, they had better glycemic control than participants randomized to the PL group. These findings support the need for larger trials.

Purpose To study the effects of noninvasive transcranial focal electrical stimulation (TFS) via tripolar concentric ring electrodes (TCRE) on the electrographic and behavioral activity from pentylenetetrazole (PTZ)-induced seizures in rats. Methods The TCREs were attached to the rat scalp. PTZ was administered and, after the first myoclonic jerk was observed, TFS was applied to the TFS treated group. The electroencephalogram (EEG) and behavioral activity were recorded and studied. Results In the case of the TFS treated group, after TFS, there was a significant (p = 0.001) decrease in power compared to the control group in delta, theta, and alpha frequency bands. The number of myoclonic jerks was significantly different (p = 0.002) with median of 22 and 4.5 for the control group and the TFS treated groups, respectively. The duration of myoclonic activity was also significantly different (p= 0.031) with median of 17.56 min for the control group versus 8.63 min for the TFS treated group. At the same time there was no significant difference in seizure onset latency and maximal behavioral seizure activity score between control and TFS treated groups. Conclusions TFS via TCREs interrupted PTZ-induced seizures and electrographic activity was reduced towards the “baseline.” The significantly reduced electrographic power, number of myoclonic jerks, and duration of myoclonic activity of PTZ-induced seizures suggests that TFS may have an anticonvulsant effect.

Obesity, hyperglycemia and dyslipidemia, are major risk factors. However, natural therapies, dietary components, and physical activity may effect on these concerns. The aim of this study was to examine the effect of aerobic exercise and consumption of liquid ginger extract on lipid profile of Male rats with a high-fat fed diet. 32 rats were randomly divided into 4 groups: 1) aerobic exercise, 2) Ginger extract, 3) combined aerobic exercise and Ginger extract, and 4) the control. Subjects of the first three groups received ginger extract via gavage feeding of 250 mg/kg. The exercise program was 3 sessions per week on 3 different days over 4 weeks. Total cholesterol (TC), Triglyceride (TG), HDL and LDL were measured 24-h before the first session and 24-h after the final training session. The concentration of TG in the control group was significantly higher than other groups. In addition, the mean concentration of TG in the aerobic exercise group was significantly lower than Ginger extract group but there was no significant difference as compared to combined aerobic exercise and ginger extract group. The combination of aerobic exercise and ginger consumption significantly reduced the TG level compared to ginger group. TC and LDL concentrations were significantly decreased in all groups compare to control. The combination of aerobic exercise and ginger extract feeding caused a significant increase in HDL levels. The finding of this study suggests that the combination of aerobic exercise and liquid ginger extract consumption might be an effective method of reducing lipid profiles, which will reduce the risk of cardiovascular diseases caused by high-fat diets.

In this study, the new antineoplastic agents titanocene dichloride and vinorelbine are compared to cisplatin and paclitaxel using a human ovarian cancer xenograft model. Biopsy material from one native human ovarian carcinoma was expanded and transplanted into 48 nude mice. The animals were divided into six treatment groups: cisplatin 3x4 mg/kg, paclitaxel 5x26 mg/kg, vinorelbine 1x20 mg/kg, titanocene dichloride 3x30 mg/kg, titanocene dichloride 3x40 mg/kg and a control group treated with 0.9% saline. Treatment groups were evaluated in terms of average daily increase in tumour volume and average daily body weight increase of the nude mice based on slopes of least square regressions performed on individual animals. The slope factors alpha and beta of the body weight (alpha) and tumour volume changes (beta) within each group were calculated. A statistically significant decrease (p<0.05) in body weight of the experimental animals was shown in groups treated with paclitaxel (alpha = -0.6878) and titanocene dichloride 3x40 mg/kg (alpha = -0.7194) compared to the control group which was treated with 0.9% saline (alpha = -0.2643). Significant body weight changes were not observed in the comparison of the remaining treated groups (cisplatin: alpha = -0.4552, vinorelbine: alpha = -0.5606, titanocene dichloride 3x30 mg/kg: alpha = -0.6173 to the control group. A significant reduction (p<0.05) of the increase tumour volume (vinorelbine: beta = 5.260, paclitaxel: beta = 0.478, titanocene dichloride 3x30 mg/kg: beta = 10.283, titanocene dichloride 3x40 mg/kg: beta = 5.768) was shown in treated groups except for cisplatin (beta = 18.722) compared to the tumour bearing control group (beta = 30.136). A statistically significant reduction of the increase in tumour volume occurred under paclitaxel medication compared to the group treated with cisplatin. We found titanocene dichloride to be effective as vinorelbine and more effective than cisplatin. Vinorelbine seems to be a very effective antineoplastic agent with a significantly higher cytostatic effect than cisplatin. Both titanocene dichloride and vinorelbine provide new therapeutic options in women with ovarian carcinoma not responding to standard chemotherapies.

To compare the effects of pneumoperitoneum on lung mechanics, end-tidal CO2 (ETCO2), arterial blood gases (ABG), and oxidative stress markers in blood and bronchoalveolar lavage fluid (BALF) during laparoscopic cholecystectomy (LC) by using lung-protective ventilation strategy. Forty-six patients undergoing LC and abdominal wall hernia (AWH) surgery were assigned into 2 groups. Measurements and blood samples were obtained before, during pneumoperitoneum, and at the end of surgery. BALF samples were obtained after anesthesia induction and at the end of surgery. Peak inspiratory pressure, ETCO2, and pCO2 values at the 30th minute were significantly increased, while there was a significant decrease in dynamic lung compliance, pH, and pO2 values in LC group. In BALF samples, total oxidant status (TOS), arylesterase, paraoxonase, and malondialdehyde levels were significantly increased; the glutathione peroxidase levels were significantly decreased in LC group. The serum levels of TOS and paraoxonase were significantly higher at the end of surgery in LC group. In addition, arylesterase level in the 30th minute was increased compared to baseline. Serum paraoxonase level at the end of surgery was significantly increased when compared to AWH group. Our study showed negative effects of pneumoperitoneum in both lung and systemic levels despite lung-protective ventilation strategy.

Postoperative ileus (POI) is one of the most common complications of gastrointestinal surgery. The present study was performed to evaluate the effects of glutamine administration on POI after gastric surgery in humans. The subjects were 31 patients who underwent partial distal gastrectomy for gastric cancer and who were randomly assigned to one of two groups based on postoperative treatment: the glutamine group (3 g/day) and the control group. Manometric recording was done 12 days after surgery, and plasma glutamine concentrations were measured preoperatively and on postoperative day 12. Motor activities of the duodenum in the glutamine group were significantly greater than those of the control group in the interdigestive state. The incidence of phase III motor activity (interdigestive migrating motor contractions) in the glutamine group was significantly higher than that in the control group (60 versus 19%). The glutamine group showed a significantly smaller decrease of plasma glutamine levels compared with the control group. Glutamine could act as a motility-recovery agent after gastrectomy in humans.

To observe the changes of intestinal inflammation on PDIA3 gene knockout IBS rats and its effect on immune function. 36 SD rats were randomly divided into four groups: the control group (n = 8); IBS- empty virus group (IBS-GFP, which); IBS-PDIA3 knockout group (n = 12); IBS- the control group (n = 12). After modeling, colon and ileocecal tissue pathology in each group were observed separately. Changes of immune and inflammatory markers were measured. At the same time, ultrastructural changes in each group were observed by electron microscopy. Compared with the IBS control group, inflammation was reduced significantly in IBS-PDIA3 knockout group. IgE, IL-4 and IL-9 and the level of intestinal trypsin type were decreased significantly. Furthermore, mast cell degranulation and PAR 2 receptor reduced significantly. PDIA3 may play an important role in the development of IBS by mediating through immune responses of mucosal abnormalities. However, the mechanism needs to be confirmed in further study.

This study was conducted to develop and to test the effects of an educational program for coping with problem situations as a nursing intervention in the diabetic patient. A non-equivalent control group pretest-posttest design was used in this study. Data were collected from January to March, 2002. The subjects of the study consisted of 31 diabetic patients(experimental group: 17 patients, control group: 14 patients). The intervention of an educational program for coping with problem situations was applied to the experimental group for 4 weeks (total 8 hours). Data were collected before the educational program, immediately after and 1 months later and were analyzed with repeated measures ANOVA, t-test, and paired t-test. 1. There was a significant difference in self efficacy between the experimental and control groups (F=13.793, p=0.001). 2. There was a significant difference in self care behavior between the experimental and control groups (F=4.583, p=0.041). 3. There was a significant difference in coping behavior of the problem situation between the experimental and control groups (F=62.018, p=0.000). There was a significant difference according to experimental stages (F=4.546, p=0.015) and interaction between education and experimental stages (F=12.039, p=0.000). 4. There was a significant difference in glycemic control between the experimental and control groups (t=-3.112, p=0.004). These results support that a diabetic educational program for coping with problem situations is effective in promoting and maintaining self efficacy, self care behavior, problem coping behaviors and in improving glycemic control. Thus this program can be recommended as an effective nursing intervention of in-depth education for diabetic patient.

Pruritus is the most common complaint in the chronic phase, with significant effects on the patient's quality of life. The current study evaluated the efficacy of a combination of one percent phenol and one percent menthol in the control of pruritus in these affected patients. This randomised, double-blinded clinical trial was performed in chemical warfare-injured veterans with mustard gas-induced pruritus. 80 subjects were selected randomly and divided into two equal groups. One group was treated with a combination of one percent phenol and one percent menthol twice a day, while the other group received a placebo. The therapeutic effects and side effects were evaluated during a six-week treatment course. Pruritus score with a range of 1-48 points was used to calculate the severity of pruritus before and after treatment in both groups. The final pruritus score in the drug group was significantly different, compared with the placebo group (p-value equals 0.03). There was also a statistically-significant difference between the pre-treatment (19 points) and post-treatment (15.5 points) pruritus scores in the drug group (p-value equals 0.001), but there was no significant difference in the response in the placebo group (p-value equals 0.66). Only a few patients had complaints about the drug, and these were generally minor. The most common complaints were of the greasy nature of the drug and its intolerable odour. A phenol one percent and menthol one percent combination has significant therapeutic effects for mustard gas-induced pruritus in chemical warfare-injured veterans, in comparison with the placebo.

The purpose of this study was to investigate the effects of hawthorn (Crataegus pinnatifida Bunge) extract on the lipid profiles and antioxidant properties in ovariectomized (OVX) rats. After ovariectomy, the rats were randomly divided into four groups: the non-OVX control (Sham), the OVX-control (OVX), the OVX + 100 mg/kg b.w. of hawthorn extract (OL), and the OVX + 200 mg/kg b.w. of hawthorn extract (OH). The final body weights of the OVX group were significantly increased, but the increment was significantly decreased in hawthorn groups (p < 0.05). The serum total and low-density lipoprotein (LDL) cholesterol levels were significantly elevated in the OVX group, whereas the hawthorn groups showed a significant decrease in these levels (p < 0.05). The hepatic triglyceride (TG) and malondialdehyde (MDA) levels were significantly reduced in the hawthorn groups compared with the OVX group (p < 0.05). The mRNA expression of nuclear factor erythroid 2–related factor (Nrf2), heme oxygenase-1 (HO-1), and glutathione peroxidase (GPx) were significantly decreased in the OVX group, whereas the hawthorn groups exhibited a significant increase in expression (p < 0.05). The protein expressions of Nrf2, HO-1, and GPx were lower in the OVX group than the Sham group (p < 0.05). The oral administration of hawthorn extract reversed the suppression of protein levels. These results suggest that hawthorn extract could have protective effects in OVX rats by improving lipid profiles, decreasing oxidative stress, and improving the antioxidant defense system.

Extensive research has been focused on radiation-induced brain injury. Animal and human studies have shown that flavonoids have remarkable toxicological profiles. This study aims to investigate the neuroprotective effects of quercetin in an experimental radiation-induced brain injury. A total of 32 adult male Wistar-Albino rats were randomly divided into four groups (control, quercetin, radiation, and radiation+quercetin groups, with eight rats in each group). Doses (50 mg/kg) of quercetin were administered to the animals in the quercetin and radiation+quercetin groups; radiation and radiation+quercetin groups were exposed to a dose of 20 Gy to the cranium region. Tissue samples, and biochemical levels of tissue injury markers in the four groups were compared. In all measured parameters of oxidative stress, administration of quercetin significantly demonstrated favorable effects. Both plasma and tissue levels of malondialdehyde and total antioxidant status significantly changed in favor of antioxidant activity. Histopathological evaluation of the tissues also demonstrated a significant decrease in cellular degeneration and infiltration parameters after quercetin administration. Quercetin demonstrated significant neuroprotection after radiation-induced brain injury. Further studies of neurological outcomes under different experimental settings are required in order to achieve conclusive results.
