    The purpose of this study is to investigate the effect of exenatide on glycemic control following two administration routes in a streptozotocin/nicotinamide (STZ/NA)-induced diabetic rat model, and to develop a pharmacodynamic model to better understand the disease progression and the action of exenatide in this experimental system. Two groups of STZ/NA-induced diabetic rats were treated for 2 weeks with 20 (μg/kg/day) of exenatide, either by continuous subcutaneous (SC) infusion or two SC injections daily. Disease progression was associated with slower glucose utilization. Fasting blood glucose was significantly reduced by 30 mg/dL in both treatment groups at the end of 2 weeks. A subsequent intravenous glucose tolerance test (IVGTT) confirmed an improved glucose tolerance in both treatment groups; however, overall glycemic control was similar between groups, likely due to the relatively low and short-term drug exposure. A population indirect response model was successfully developed to simultaneously describe the STZ/NA-induced disease progression, responses to an IVGTT, and exenatide effects on these systemic challenges. The unified model includes a single set of parameters, and the cumulative area under the drug-receptor concentration curve was used as a unique driving force to account for systemic effects long after drug elimination.

    Abstract As there are increasing reports of fluoroquinolone resistance on use as a first- or second-line treatment for Helicobacter pylori (H pylori), we aimed at evaluation of the efficacy and safety of nitazoxanide-based regimen as a rescue regimen in Egyptian patients whose previous traditional treatment for H pylori infection failed.In total, 100 patients from the outpatient clinic of the Tropical medicine department, Tanta University hospital in whom the standard triple therapy (clarithromycin-based triple therapy) failed were enrolled in the study. Nitazoxanide (500 mg bid), levofloxacin (500 mg once daily), omeprazole (40 mg bid), and doxycyclin (100 mg twice daily) were prescribed for 14 days. Eradication was confirmed by stool antigen for H pylori 6 weeks after the end of treatment. Among the patients enrolled in the study, 44% of patients were men and the mean age for the participants in the study was 46.41 ± 8.05, 13% of patients were smokers, and 4% of patients had a previous history of upper gastro-intestinal bleeding. A total of 94 patients (94%) completed the study with excellent compliance. Only 1 patient (1%) discontinued treatment due to intolerable side effects and 5 patients (5%) did not achieve good compliance or were lost during follow up. However, 83 patients had successful eradication of H pylori with total eradication rates 83% (95 % CI 75.7–90.3%) and 88.30% (95 % CI 81.8–94.8%) according to an intention-to-treat and per-protocol analysis, respectively. Adverse events were reported in 21% of patients: abdominal pain (6%), nausea (9%) and constipation (12%), (2%) headache, and (1%) dizziness. A 2-week nitazoxanide-based regimen is an effective and safe rescue therapy in Egyptian patients whose previous standard triple therapy has failed. PMID:27310977

    Background Cyclo-oxygenase inhibitors (COX-I) treatment of patent ductus arteriosus (PDA) in very low birth weight (VLBW) infants during the early postnatal period is well established, but their use beyond early postnatal period is not well studied. Objective The objective of this study was to determine the effectiveness of postnatal COX-I for PDA treatment beyond 2 weeks of age in VLBW infants. Study Design A retrospective cohort of VLBW infants admitted to two tertiary NICUs between 1990 and 2008 were studied. Infants with symptomatic PDA were treated with COX-I and infants with failed medical treatment were candidates for surgical ligation. Effectiveness of COX-I treatment, measured by the need for surgical ligation, was compared between early (day of life [DOL] < 14, early treatment group [ETG]) and late (DOL ≥ 14, late treatment group [LTG]) treatment groups. Results Of the 1,289 infants with PDA, 1,082 (84%) were treated with COX-I; 1,046 (97%) infants were in ETG and 36 (3%) in LTG. PDA ligation rates after COX-I treatment were 15% in ETG and 14% in LTG (p-value: not significant). There were no significant differences in demographics or morbidities between the two groups. Conclusions In VLBW infants, late treatment of PDA with COX-I was as effective as early treatment. Trial of late COX-I treatment is warranted for symptomatic PDA before surgical treatment.

    This study was performed to investigate the effect of of transdermal testosterone gel (TTG) on controlled ovarian stimulation (COS) and IVF outcomes and ovarian morphology according to pretreatment duration in poor responders. A total of 120 women were recruited for this pilot study. They were randomized into control, 2 weeks, 3 weeks or 4 weeks TTG treatment groups. For three TTG treatment groups, 12.5 mg TTG was applied daily for 2 weeks, 3 weeks or 4 weeks in preceding period of study stimulation cycle. After 3 weeks of TTG pretreatment, significant increase of antral follicle count (AFC) and significant decreases of mean follicular diameter (MFD) and resistance index (RI) value of ovarian stromal artery were observed (p=0.026, p<0.001, p<0.01, respectively). The total dose of rhFSH administered for COS significantly decreased after 3 and 4 weeks TTG treatment both compared with control group (p<0.001, p<0.001). The numbers of oocytes retrieved and mature oocytes were significanty higher in 3 and 4 weeks TTG treatment groups than control group (p<0.001, p<0.001 in the number of oocytes retrieved; p<0.001, p<0.001 in the number of mature oocytes). The clinical pregnancy rate and live birth rate were increased only in 4 weeks TTG treatment group compared with control group (p=0.030 and p=0.042, respectively). These data demonstrated that TTG pretreatment for 3 to 4 weeks increases AFC and ovarian stromal blood flow, thereby potentially improving the ovarian response to COS and IVF outcome in poor responders undergoing IVF/ICSI.

    A randomized, controlled, crossover clinical study compared 14-night treatment with 15 mg temazepam, 50 mg diphenhydramine, and placebo in elderly individuals with insomnia (mean age, 73.9 years; range, 70-89 years). Primary outcome measures were subjective assessments of sleep recorded on sleep diaries. Secondary measures were the morning-after psychomotor impairment, using the digit symbol substitution task and the manual tracking task, and the morning-after memory impairment, using a free-recall procedure. Results showed sleep improvements with 15 mg temazepam compared with placebo-sleep quality (mean score, 3.3 +/- 0.9 vs 2.9 +/- 0.8; P = 0.03), total sleep time (6.9 +/- 1.0 hours vs 6.3 +/-1.3 hours; P = 0.02), number of awakenings (1.5 +/- 1.3 vs 2.0 +/- 1.2; P < 0.001), and sleep-onset latency (25 +/- 22 minutes vs 37 +/- 25 minutes; P = 0.03). Improvements were seen with diphenhydramine treatment compared with placebo on the number of awakenings only (mean, 1.7 +/- 1.1 vs 2.0 +/- 1.2; P < 0.05). Numbers of adverse events reported were similar after all treatments, although there was 1 fall during temazepam treatment. Findings indicate that temazepam is more effective than diphenhydramine when compared with placebo at the doses tested, although this advantage is mitigated by the risk of falls associated with temazepam use. The choice of agent to use in the elderly must consider these relative benefits and risks. PMID:18344728

    Background. Multiple weight loss failures among obese patients suggest the design of new therapeutic strategies. We investigated the role of 2-week course of enteral treatment with a very low-calorie protein-based formula in the management of severe obesity. Methods. We evaluated the feasibility, safety, and efficacy of 2-week continuous administration of a protein-based formula (1.2 g/kg of ideal body weight/day) by nasogastric tube in severely obese adults (body mass index (BMI) ≥ 40 kg/m2). Results. In total, 364 patients (59% women; BMI = 46.6 ± 7.2 kg/m2) were recruited. The intervention was discontinued within 48 hours in 26 patients, due to nasogastric tube intolerance. No serious adverse events occurred. During the first and the second week, 65% and 80% patients, respectively, reported no side effects. All biochemical safety parameters were affected by the intervention, particularly uric acid (+45%) and aminotransferases (+48%). In the other cases the change was negligible. We observed significant weight loss (5.7 ± 2.3%) and improvement in blood pressure and glucose and lipid metabolism parameters (P < 0.001). Conclusions. A 2-week course of enteral treatment with a very low-calorie protein-based formula appeared a feasible, likely safe, and efficacious therapeutic option to be considered for inclusion into a composite weight loss program for the management of severe obesity.

    Previously we demonstrated that the mouse liver tumor response to the non-genotoxic carcinogens oxazepam and Wyeth-14,643 involved more differences than similarities in changes in early gene expression. In this study we used quantitative real-time PCR and oligonucleotide microarray analysis to identify genes that were up- or down-regulated in mouse liver early after treatment with different known carcinogens, including oxazepam (125 and 2500 p.p.m.), o-nitrotoluene (1250 and 5000 p.p.m.) and methyleugenol (75 mg/kg/day), or the non-carcinogens p-nitrotoluene (5000 p.p.m.), eugenol (75 mg/kg/day) and acetaminophen (6000 p.p.m.). Starting at 6 weeks of age, mice were treated with the different compounds for 2 weeks in the diet, at which time the livers were collected. First, expression of 12 genes found previously to be altered in liver after 2 weeks treatment with oxazepam and/or Wyeth-14,643 was examined in livers from the various chemical treatment groups. These gene expression changes were confirmed for the livers from the oxazepam-treated mice in the present study, but were not good early markers for all the carcinogens in this study. In addition, expression of 20 842 genes was assessed by oligonucleotide microarray [n = 4 livers/group, 2 hybridizations/liver (with fluor reversals)] and the results were analyzed using the Rosetta Resolver System and GeneSpring software. The analyses revealed that several cancer-related genes, including Fhit, Wwox, Tsc-22 and Gadd45b, were induced or repressed in unique patterns for specific carcinogens and not altered by the non-carcinogens. The data indicate that even if the tumor response, including molecular alterations, is similar, such as for oxazepam and methyleugenol, early gene expression changes appear to be carcinogen specific and seem to involve apoptosis and cell cycle-related genes.

    Efficacy and safety of azithromycin and doxycycline for the treatment of moderate acne vulgaris were evaluated (240 patients) in both intention-to-treat and per-protocol populations. The evaluation of clinical efficacy was based on the change in the number of facial inflammatory lesions from baseline to the end of treatment, and noninferiority was defined by the upper 95% confidence limit of the difference between two treatments being less than 9. Reduction in the number of lesions was similar with both azithromycin and doxycycline treatments (27 +/- 12 and 30 +/- 12, respectively) in both groups. Also, the upper 95% confidence limit of 5 inflammatory lesions has satisfied the noninferiority criterion. The incidence of adverse events did not differ between the two treatment groups. The shorter and simpler treatment schedule of azithromycin had similar efficacy and safety as doxycycline in the treatment of moderate acne vulgaris, confirming noninferiority of azithromycin as compared with doxycycline.

    An important clinical question is the relative efficacy of the most common dosages of darbepoetin alfa (Aranesp; Amgen Inc.; Thousand Oaks, CA) 200 microg every 2 weeks (Q2W) and epoetin alfa (Procrit; Ortho Biotech Products, LP; Raritan, NJ) 40,000 U weekly (QW) for the treatment of chemotherapy-induced anemia. We designed three concurrent randomized, open-label, multicenter, identical trials (with the exception of tumor type criteria of breast, gynecologic, or lung cancer) of darbepoetin alfa and epoetin alfa in patients with chemotherapy-induced anemia to validate the Patient Satisfaction Questionnaire for Anemia (PSQ-An) treatment tool and to compare the efficacies and safety profiles of these two agents. In each trial, patients were randomized 1:1 to receive either darbepoetin alfa at a dose of 200 microg Q2W or epoetin alfa at a dose of 40,000 U QW for up to 16 weeks. The PSQ-An was assessed for validity, feasibility, and reliability. Secondary clinical endpoints were analyzed using the primary analysis set. Both individual trial analyses and a protocol-specified combined analysis of data from all three trials were conducted. Overall, 312 patients (157 darbepoetin alfa; 155 epoetin alfa) were randomized and received study drug. Baseline characteristics were similar in both treatment groups in each trial and overall. The PSQ-An was valid, feasible, and reliable. In general, no difference between treatment groups was observed for hemoglobin- and transfusion-based endpoints in each individual trial or in the combined analysis. From exploratory analyses, achievement and maintenance of a hemoglobin target range (11-13 g/dl) were similar in both groups. No differences in safety were observed. With the PSQ-An, formal comparisons of the impact of anemia therapies on patients and caregivers can be made in future prospective studies. Further, darbepoetin alfa (200 microg Q2W) and epoetin alfa (40,000 U QW) appear to achieve comparable clinical and hematologic outcomes

    Background: The overexcitation of the N-methyl-D-aspartate receptor complex appears to play a critical role in the development of neuropathic pain, and ketamine acts as an antagonist to that receptor. Some publications have reported on the prominent relief of neuropathic pain with intravenous or subcutaneous ketamine infusions or a single-dose intravenous ketamine injection despite adverse effects. Objectives: The primary objective of this study was to determine the analgesic effect of intravenous ketamine infusion therapy for neuropathic pain refractory to conventional treatments. Secondary objectives included identifying the variables related to the analgesic effect and the pain descriptors susceptible to ketamine infusion. Methods: This 2-week, open-label, uncontrolled study was conducted in Korean patients with neuropathic pain recruited from the Samsung Seoul Hospital (Seoul, Republic of Korea) outpatient pain management unit. Patients were required to have a pain severity score >5 (visual analog scale [VAS], where 0 = no pain and 10 = worst pain imaginable) over a period of ≥1 month while on standard treatment. The patients were required to have shown no benefit from standard treatment and no pain relief lasting over 1 month. The ketamine infusion therapy was composed of 3 sessions performed consecutively every other day. Midazolam was administered concomitantly to reduce the occurrence of central nervous system-related adverse events (AEs) secondary to ketamine. Each session was as follows: ketamine 0.2 mg/kg and midazolam 0.1 mg/kg were administered intravenously for 5 minutes as a loading dose, followed by a continuous infusion of ketamine 0.5 mg/kg/h and midazolam 0.025 mg/kg/h for 2 hours. AEs were assessed in the following ways: close monitoring of ECG, blood pressure, oxygen saturation, and evaluating the need for treatment of AEs during infu- sion and until discharge by an attending anesthesiologist; an open question about discomfort at the end of

    The perinatal period is a time of high risk for women with unipolar and bipolar mood disorders. We discuss treatment considerations for perinatal mood disorders, including unipolar and bipolar depression as well as postpartum psychosis. We further explore the unique issues faced by women and their families across the full trajectory of the perinatal period from preconception planning through pregnancy and following childbirth. Treatment of perinatal mood disorders requires a collaborative care approach between obstetrics practitioners and mental health providers, to ensure that a thoughtful risk : benefit analysis is conducted. It is vital to consider the risks of the underlying illness versus risks of medication exposure during pregnancy or lactation. When considering medication treatment, attention must be paid to prior medication trials that were most efficacious and best tolerated. Lastly, it is important to assess the impact of individual psychosocial stressors and lifestyle factors on treatment response. PMID:26246794

    In 145 patients with unstable angina (UA) there was analized an efficiency of a drug therapy at different types of heliogeophysical activity (HA) during the 23th solar cycle. 83 patients were examined at the period of a lower HA (Kp-index 16,19±0,18), and 62 patients - at the period of a higher HA (Kp-index 17,25±0,21, p<0,05). Baseline severity of patients' condition with UA at the moment of hospitalization at the studied periods did not differ, but the effectiveness of the therapy depended on the period of HA. At the period of a higher HA antianginal effect was stronger than at the lower period of HA (2,27±0,16 points and 1,75±0,12 points, p<0,05), and the need in nitroglycerin on the background of a drug therapy disappeared for 5-7 days quicker than at the period of a lower HA. Maximal hypotensive effect at a higher HA was achieved quicker - on the 3rd day of the treatment, and at a lower HA - only up to hospital discharge (p<0,05). Blood viscosity did not normalize in both of the studied periods, but in small vessels there was noted a decrease of a BV (p<0,05). So, at a higher HA the effectiveness of a drug therapy in patients with UA is higher than at the period of a lower HA.

    Limited contaminant bioavailability at concentrations above the required cleanup level reduces biodegradation rate and renders solid-phase bioremediation more cost effective than complete treatment in a bioslurry reactor. Slurrying followed by solid-phase bioremediation combines the advantages and minimizes the weaknesses of each treatment method when used alone. Periodic aeration during solid-phase bioremediation has the potential to lower treatment costs relative to continuous aeration. A biological treatment system consisting of slurrying followed by periodic aeration in solid-phase sequencing batch reactors (SP-SBRs) was developed and tested in the laboratory using a silty loam contaminated predominantly with the plasticizer bis(2-ethylhexyl)phthalate (BEHP) or (DEHP) and a silty clay loam contaminated with diesel fuel. The first experiment evaluated the effect of water content and mixing time during slurrying on subsequent treatment in continuously aerated solid-phase bioreactors. The second experiment compared treatment of slurried soil in SP-SBRs using three different periodic aeration strategies with continuous aeration.

    Chlorine dioxide was injected into the water intakes at two power plants in Illinois and one in Indiana in an effort to eradicate the existing population of zebra mussels and mitigate further settlement in station river water cooling systems. Results of the treatments at Illinois Power Company`s Wood River Station on the Mississippi River, Central Illinois Public Service`s Meredosia Station on the Illinois River, and SI Energy`s Gallagher Station on the Ohio River are reported. Treatments were performed on a turnkey basis, with three treatments performed at Meredosia Station in 1994, six treatments performed at Wood River Station between July 1993 and September 1994, and 2 treatments performed at Gallagher Station in 1994. For each treatment, a contractor installed and operated a portable chlorine dioxide generator, monitored water quality and oxidant levels, and provided and monitored bioboxes containing test mussels. Results of the treatments were very favorable, indicating a good potential for periodic treatments with chlorine dioxide to control zebra mussel infestations in the raw water systems of power plants and other industrial facilities. Some difficulties with the chlorine dioxide generation system and cold temperature effects reduced the treatment effectiveness, particularly the second treatment at Gallagher Station. Average induced mortalities ranged from 70 to 100% at Wood River, 87 to 92% at Meredosia, and 30 to 100% at Gallagher for native mussels. Dechlorination successfully kept total oxidant residual levels at or below 0.05 ppM during all treatments at all stations.

    In the summer of 1982, Texas Scottish Rite Hospital (Dallas, TX, U.S.A.) sponsored a camp for paraplegic adolescents. Six patients, three boys and three girls 14-17 years of age, participated in a 2-week program that was designed to improve their self-esteem, independence, and eventual employability. In their pre- and postcamp psychological evaluations, the campers demonstrated improvement in social skills and self-concept testing as compared with the scores of a matched control group, although this improvement did not reach statistical significance. We believe the camp was immensely successful, an opinion that was shared by both the campers and their parents. PMID:3514667

    The nervous system is vulnerable to perturbations during specific developmental periods. Insults during such susceptible time windows can have long-term consequences, including the development of neurological diseases such as epilepsy. Here we report that a pharmacological intervention timed during a vulnerable neonatal period of cortical development prevents pathology in a genetic epilepsy model. By using mice with dysfunctional Kv7 voltage-gated K(+) channels, which are mutated in human neonatal epilepsy syndromes, we demonstrate the safety and efficacy of the sodium-potassium-chloride cotransporter NKCC1 antagonist bumetanide, which was administered during the first two postnatal weeks. In Kv7 current-deficient mice, which normally display epilepsy, hyperactivity and stereotypies as adults, transient bumetanide treatment normalized neonatal in vivo cortical network and hippocampal neuronal activity, prevented structural damage in the hippocampus and restored wild-type adult behavioral phenotypes. Furthermore, bumetanide treatment did not adversely affect control mice. These results suggest that in individuals with disease susceptibility, timing prophylactically safe interventions to specific windows during development may prevent or arrest disease progression.

    The paper reports the results obtained during an experimental campaign aimed at transferring aerobic granulation to a demonstrative SBBGR system (i.e., a submerged biofilter that operates in a "fill and draw" mode) for the treatment of municipal wastewater by financial support of the European Commission, within the framework of Life-Environment Programme (PERBIOF Project; www.perbiof-europe.com). The results show that following the generation of granular biomass during the start-up period, the SBBGR was able to remove 80-90% of COD, total suspended solids and ammonia occurring in primary effluent from a municipal wastewater treatment plant even when the minimum hydraulic residence time (i.e., 4 h) was investigated. The process was characterised by a sludge production almost one magnitude order lower than commonly reported for conventional treatment plants. The granular biomass was characterised by a high density (i.e., 150 gTSS/L(biomass)) that allowed a biomass concentration as high as 35 kgTSS/m(3)(bed) to be achieved. Proteobacteria were found as main microbial components of the granular biomass by applying Fluorescence In Situ Hybridization (FISH). No significant changes in microbial composition were observed during reactor operation. PMID:19092218

    Chemotherapy with cisplatin plus fluorouracil is the current standard treatment for metastatic or recurrent esophageal cancer. We have developed a 2-weekly docetaxel combined with CF regimen and conducted a Phase I/II trial for metastatic or recurrent esophageal cancer (JCOG0807). Promising efficacy and safety were shown in JCOG0807, and we have commenced a Phase III trial in September 2014 to confirm the superiority of 2-weekly DCF to CF for patients with metastatic or recurrent esophageal cancer. A total of 240 patients will be accrued from 41 Japanese institutions over a period of 4 years. The primary end point is overall survival. The secondary end points are progression-free survival, response rate and proportion of adverse events. This trial has been registered in the UMIN Clinical Trials Registry as UMIN000015107 (http://www.umin.ac.jp/ctr/index.htm). PMID:25646357

    Staphylococcus aureus is the most commonly isolated pathogen in respiratory tract secretions from young patients with cystic fibrosis (CF), and several treatment strategies are used to control the infection. However, it is not known whether intensified treatment with antimicrobial agents causes eradication of S. aureus clones. We retrospectively determined the impact of intravenous (IV) antimicrobial agents on the suppression and eradication of S. aureus clones. One thousand and sixty-one S. aureus isolates cultured from 2526 samples from 130 CF patients during a 2-year study period were subjected to spa typing. Intervals between positive samples and the occurrence of clone replacements were calculated in relation to courses of IV antimicrobial agents. Of 65 patients chronically infected with S. aureus, 37 received 139 courses of IV antimicrobial agents with activity against S. aureus (mean duration, 15 days; range, 6-31 days). Administration of IV antibiotics increased the time to the next sample with growth of S. aureus: the mean interval between two positive samples was 68 days if IV treatment had been administered, in contrast to 49 days if no IV treatment had been administered (p 0.003). When S. aureus recurred in sputum after IV treatment, the isolate belonged to a different clone in 33 of 114 (29%) intervals, in comparison with 68 of 232 (29%) intervals where IV treatment had not been prescribed (OR 0.98, 95% CI 0.60-1.61). In conclusion, we show that 2 weeks of IV antimicrobial treatment can significantly suppress chronic staphylococcal infection in CF, but is not associated with the eradication of persistent bacterial clones.

    The aim was to compare the acute hormonal response to a single HIT session at the beginning and end of a HIT shock microcycle. 13 male junior triathletes (15.8±1.8 yrs.) performed 16 HIT sessions within a 2 week period. Venous blood samples were collected before and after the first and last HIT session. Significant increases in cortisol (first session +89.7%; last session +70.3%) and hGH (first session +435.1%; last session +314.6%) concentrations were observed after both training sessions (P<0.05). The acute responses of cortisol, hGH, T3, and fT3 were not different between the first and last HIT sessions (P=1.00). Although no acute changes in testosterone were detected after the training sessions, testosterone concentrations were significantly higher at all time points (62.6-80.1%) during the last compared to first training session (P≤0.001). Findings from the present study reveal that 16 sessions of HIT led to significant increases in baseline concentrations of serum testosterone. This might indicate a heightened anabolic state even in junior triathletes. Based on the hormonal data, we conclude that at the end of this 2 week microcycle no familiarization effect was evident and that the training stimulus produced by HIT was still great enough to "stress" the athletes and induce positive training adaptations.

    A total of 108 patients have filled in questionnaires on falling asleep, sleeping, night awakenings and other characteristics. Their answers have been analysed and it was concluded that night sleep of patients especially in the postoperative period was characterized by prolonged period of falling asleep (over 30 min in 50% of patients), reduced duration, in 77% of patients night awakenings have been recorded. The use of analgin (1000 mg) in combination with dimedrol (10 mg), promedol (20 mg) for tramal (100 mg) for normalization of sleep in the postoperative period was of little efficacy. Therapy of night sleep disturbances will improve the patients' condition and enhance the efficacy of management after surgical interventions. PMID:8010509

    Objective Empirical studies have now established that clinical anxiety and depressive disorders may arise in preschool children as early as age 3.0. As empirical studies validating and characterizing these disorders in preschoolers are relatively recent, less work has been done on the development and testing of age-appropriate treatments. Method A comprehensive literature search revealed several small randomized controlled trials (RCTs) of psychotherapeutic treatments for preschool anxiety and depression. The literature also contains case series of behavioral and psychopharmacologic interventions for specific anxiety disorders. However, to date, no large-scale RCTs of treatment for any anxiety or depressive disorder specifically targeting preschool populations have been published. Results Several age-adapted forms of cognitive behavioral therapy have been developed and preliminarily tested in small RCTs, and appear promising for a variety of forms of preschool anxiety disorders. Notably, these adaptations centrally involve primary caregivers and utilize age-adjusted methodology such as cartoon-based materials and co-constructed drawing or narratives. Modified forms of Parent Child Interaction Therapy (PCIT) have been tested and appear promising for both anxiety and depression. While preventive interventions that target parenting have shown significant promise in anxiety, these methods have not been explored in area of early childhood depression. Studies of the impact of parental treatment on infants suggest that direct treatment of the youngest children may be necessary to affect long-term change. Conclusions Recommendations are made for clinical treatment of these disorders where psychotherapy is the first line of intervention. PMID:23582866

  6. Chronic Alcohol Treatment in Rats Alters Sleep by Fragmenting Periods of Vigilance Cycling in the Light Period with Extended Wakenings

    2009-01-01

    Studies have shown that disturbed sleep produced by chronic alcohol abuse in humans can predict relapse drinking after periods of abstinence. How alcohol produces disturbed sleep remains unknown. In this study we used a novel analysis of sleep to examine the effects of alcohol on sleep patterns in rats. This analysis separates waking into multiple components and defines a period labeled vigilance cycling (VC) in which the rat rapidly cycles through various vigilance states. These VC episodes are separated by long duration wake periods (LDW). We find that 6 weeks of alcohol (6% in a liquid diet) caused fragmentation of extended VC episodes that normally occur in the light period. However, total daily amounts of slow-wave sleep (SWS) and rapid-eye movement sleep (REMS) remained constant. The daily amount of wake, SWS, and REMS remained constant because the alcohol treated rats increased the amount of VC in the dark period, and the sleep nature of VC in the dark period became more intense. In addition, we observed more wake and less REMS early in the light period in alcohol treated rats. All effects completely reversed by day 16 of alcohol withdrawal. Comparison of the effects of chronic alcohol to acute alcohol exposure demonstrated the effects of chronic alcohol are due to adaptation and not the acute presence of alcohol. The effects of chronic alcohol treatment in rats mimic the effects reported in humans (REMS suppression, difficulty falling asleep, and difficulty remaining asleep). PMID:19014977

    This paper summarizes the EPRI report (TR-105202) on the same topic as well as presents changes in current thinking on the suitability (applicability) of chlorine dioxide for fouling control. Chlorine dioxide was tested as a zebra mussel biocide at two steam electric generating stations in Illinois and one in Indiana. The purpose of these studies was to determine the efficacy of chlorine dioxide in killing zebra mussels and to develop site specific treatment programs for the three utilities. The Electric Power Research Institute (EPRI) Zebra Mussel Consortium sponsored the testing of this recent use of chlorine dioxide. The raw water system at Central Illinois Public Service`s Meredosia Station, on the Illinois River, received applications of chlorine dioxide in April, July, and September 1994. The raw water system at Illinois Power Company`s Wood River Station, on the Mississippi River, received applications in July 1993, January, April, May, July, and September 1994. The Gallagher Station, on the Ohio River, was treated in July and October 1994. Chlorine dioxide was generated on-site and injected into the water intake structure. Both cooling and service water systems were treated at the facilities. 6 refs., 13 figs.

    We carried out a phase I/II trial of adding 2-weekly docetaxel to cisplatin plus fluorouracil (CF) therapy (2-weekly DCF regimen) in esophageal cancer patients to investigate its safety and antimetastatic activity. Patients received 2-weekly docetaxel (30 mg/m(2) [dose level (DL)1] or 40 mg/m(2) [DL2] with a 3 + 3 design in phase I, on days 1 and 15) in combination with fixed-dose CF (80 mg/m(2) cisplatin, day 1; 800 mg/m(2) fluorouracil, days 1-5) repeated every 4 weeks. The primary endpoint was dose-limiting toxicity (DLT) in phase I and central peer review-based response rate in phase II. At least 22 responders among 50 patients were required to satisfy the primary endpoint with a threshold of 35%. Sixty-two patients were enrolled in phase I and II. In phase I, 10 patients were enrolled with DLT of 0/3 at DL1 and 2/7 in DL2. Considering DLT and treatment compliance, the recommended phase II dose was determined as DL1. In phase II, the response rate was 62% (P < 0.0001; 95% confidence interval, 48-75%); median overall survival and progression-free survival were 11.1 and 5.8 months, respectively. Common grade 3/4 adverse events were neutropenia (25%), anemia (36%), hyponatremia (29%), anorexia (24%), and nausea (11%). No febrile neutropenia was observed. Pneumonitis caused treatment-related death in one patient. The 2-weekly DCF regimen showed promising antimetastatic activity and tolerability. A phase III study comparing this regimen with CF therapy is planned by the Japan Clinical Oncology Group. This study was registered at the UMIN Clinical Trials Registry as UMIN 000001737.

    In 2006, the Adjuvant Chemotherapy Trial of S-1 for Gastric Cancer (ACTS-GC) demonstrated that S-1 is an effective adjuvant therapy for gastric cancer. Following that study, S-1 has been used as the standard adjuvant therapy for gastric cancer in Japan. However, the 1-year completion rate was only 65.8% in the ACTS-GC study and feasibility remains a critical issue. We conducted a study to evaluate the feasibility of 2 weekly administration regimens of S-1 as adjuvant chemotherapy in gastric cancer. The criteria for eligibility included histologically proven stage II (excluding T1), IIIA or IIIB gastric cancer with D2 lymph-node dissection. The patients were randomly assigned to either arm A (S-1 administration for 4 weeks followed by 2 weeks of rest) or arm B (S-1 administration for 2 weeks followed by 1 week of rest). In each arm, treatment was continued for 12 months unless recurrence or severe adverse events were observed. The primary endpoint was feasibility (protocol treatment completion rate). The secondary endpoints were safety, relapse-free survival and overall survival. A total of 47 patients were assigned to arms A or B between May, 2008 and February, 2010. During the first interim analysis, the protocol treatment completion rates in arms A and B were 83 and 100%, respectively at 6 months and 49 and 89%, respectively, at 12 months (P=0.0046). Therefore, S-1 administration for 2 weeks followed by 1 week rest was more feasible as adjuvant chemotherapy in gastric cancer. Grade 3 adverse events in arm A included fatigue (8.0%), anorexia (8.0%), nausea (4.0%), vomiting (4.0%) and hand-foot syndrome (4.0%), whereas none were observed in arm B. There were no reported grade 4 adverse events in either arm. In conclusion, the 2-week S-1 administration followed by 1-week rest regimen appears to be a more feasible oral administration regimen for S-1 as adjuvant chemotherapy in gastric cancer.

    Purpose This study assessed the efficacy of methylphenidate versus placebo for cancer-related fatigue reduction. Other objectives were to analyze cytokine levels and to determine the effects of methylphenidate on other symptoms, cognitive function, work yield, and patients’ perceptions, and preferences. Methods Patients were randomly assigned (1:1) to receive methylphenidate-placebo or placebo-methylphenidate for 4 weeks. Patients crossed over after 2 weeks. Wilcoxon signed-rank tests and McNemar tests were used to assess continuous and categorical variables. The primary efficacy end point was change in the level of worst fatigue on the Brief Fatigue Inventory at the end of each 2-week period. Results The mean baseline Brief Fatigue Inventory was moderate (5.7). Methylphenidate treatment did not affect patients’ worst level of fatigue or other symptoms. Results from the Wechsler Adult Intelligence Scale Digit Symbol Test and the Hopkins Verbal Learning Test with Brief Fatigue Inventory interference questions and Brief Fatigue Inventory activity questions showed significant improvement in the methylphenidate-treated patients’ verbal learning, memory, visual perception, analysis, and scanning speed. Patients treated with methylphenidate missed significantly fewer work hours owing to health reasons and worked significantly more hours. After 4 weeks, 64% of patients reported that methylphenidate improved their cancer-related fatigue, and 58% wanted to continue treatment. Significant difference in IL-6R (positive), IL-10 (negative) and TNFα (positive) was noted between the methylphenidate and the placebo group. Discussion Low-dose methylphenidate did not improve cancer-related fatigue. Patients taking methylphenidate had better cognition and were able to work more hours. Patients tolerated methylphenidate well, and a majority felt better and wanted to continue treatment. PMID:24445757

    The response to a time periodic treatment of the immunotherapy in a stochastic model of tumor-immune interaction is numerically investigated. Due to the effect of synchronization among the intrinsic oscillation and the treatment, an enhanced extinction of the tumor cells is observed. It suggests that compared with the static treatment, by controlling the period of the treatment, the time periodic treatment could be an effective way of treatment leading to tumor extinction.

    Introduction. The Department for Internal and Integrative Medicine in Essen utilizes mind/body medical elements in order to empower patients with chronic diseases to better cope with their symptoms and to adopt a healthy lifestyle. This study explored the influence and predictors of a 2-week integrative treatment program on patients' quality of life. Methods. This observational study was conducted with inpatients as part of the quality assurance program. Patients' quality of life, psychological symptoms, and health locus of control were measured on admission and discharge and again 3, 6, and 12 months after discharge. Regression analyses were conducted to determine the factors predicting improved quality of life. Results. Data from 2486 inpatients treated in 2001–2004 were included (80% female, mean age 53.9 ± 14.3 years). Response rates decreased to 50% at 12 months. Small-to-moderate effects were found on patients' quality of life, anxiety, and depression. Patients' internal locus of control significantly increased. Improved quality of life was mainly predicted by lower baseline scores. Conclusion. Results of this study suggest that a 2-week inpatient treatment might sustainably reduce patients' symptoms and increase their quality of life; however, conclusions are only preliminary. More research is needed to enable the effectiveness to be judged conclusively. PMID:23133499

    In this paper, the stochastic resonance phenomenon in a tumor growth model under subthreshold periodic therapy and Lévy noise excitation is investigated. The possible reoccurrence of tumor due to stochastic resonance is discussed. The signal-to-noise ratio (SNR) is calculated numerically to measure the stochastic resonance. It is found that smaller stability index is better for avoiding tumor reappearance. Besides, the effect of the skewness parameter on the tumor regrowth is related to the stability index. Furthermore, increasing the intensity of periodic treatment does not always facilitate tumor therapy. These results are beneficial to the optimization of periodic tumor therapy.

    Purpose: High-intensity short-duration interval training (HIT) stimulates functional and metabolic adaptation in skeletal muscle, but the influence of HIT on mitochondrial function remains poorly studied in humans. Mitochondrial metabolism as well as mitochondrial-associated protein expression were tested in untrained participants performing HIT over a 2-week period. Methods: Eight males performed a single-leg cycling protocol (12 × 1 min intervals at 120% peak power output, 90 s recovery, 4 days/week). Muscle biopsies (vastus lateralis) were taken pre- and post-HIT. Mitochondrial respiration in permeabilized fibers, citrate synthase (CS) activity and protein expression of peroxisome proliferator-activated receptor gamma coactivator (PGC-1α) and respiratory complex components were measured. Results: HIT training improved peak power and time to fatigue. Increases in absolute oxidative phosphorylation (OXPHOS) capacities and CS activity were observed, but not in the ratio of CCO to the electron transport system (CCO/ETS), the respiratory control ratios (RCR-1 and RCR-2) or mitochondrial-associated protein expression. Specific increases in OXPHOS flux were not apparent after normalization to CS, indicating that gross changes mainly resulted from increased mitochondrial mass. Conclusion: Over only 2 weeks HIT significantly increased mitochondrial function in skeletal muscle independently of detectable changes in mitochondrial-associated and mitogenic protein expression.

    Recently, nonequilibrium atmospheric-pressure plasmas have been intensively studied for biological applications. However, the each effect of species in plasmas to biological tissue has not been clarified yet because various factors exist in the plasmas. Accordingly, we have studied effects of atomic oxygen dose on cell growth such as budding yeast and mouse NIH3T3 fibroblasts of mammalian cells. Both of cells were suspended with PBS, and treated using oxygen radical source. In order to prevent the radicals from reacting with the ambient air, the treatment region was surrounded by a plastic cover and purged with Ar. The proliferative effect of 15 % was observed at the O3Pj dose of around 1 . 0 ×1017 cm-3 in NIH3T3 cells as well as in yeast cells. Moreover, periodic oxygen treatment enhanced the effect in budding yeast cells. The best interval of periodic oxygen radical treatment was around 2 hours, which is almost the same period as that of their cell cycle. With the optimum interval time, we have investigated the effect of the number of the treatments. As the number of treatments increases, the growth rate of budding yeast cells was gradually enhanced and saturated at thrice treatments. This work was partly supported by JSPS KAKENHI Grant Numbers 26286072 and project for promoting Research Center in Meijo University.

    A double blind, randomized, controlled study with three parallel treatment groups was done to evaluate the efficacy of a Terminalia chebula 10% mouth rinse compared with chlorhexidine 0.12% mouth rinse, applied two times daily for 2 weeks, in the treatment of dental plaque and gingivitis. Seventy-eight patients were included in the study. The efficacy variables were periodontal indices on days 0, 7 and 14 after commencement of therapy. Twenty six patients received chlorhexidine mouth rinse, twenty six Terminalia chebula mouth rinse and twenty six received saline solution. The clinical parameters were significantly reduced by both chlorhexidine and Terminalia chebula mouth rinse although no significant difference was seen between the two groups (P > 0.05). This study demonstrated that Terminalia chebula mouth rinse is effective in reducing microbial plaque, gingival inflammation and neutralizing salivary pH. PMID:24123617

    A method for easy and fast regeneration of aqueous periodate solutions from dialdehyde cellulose (DAC) production by ozone treatment is presented, along with a direct and reliable simultaneous quantification of iodate and periodate by reversed-phase HPLC. The influence of iodate and ozone concentration, solution pH, and reaction time on the regeneration efficiency was studied, as well as the reaction kinetics. Regeneration of spent periodate solutions by ozone was successfully performed in alkaline medium, which favors the formation of free (.) OH radicals, as supported by the addition of radical scavengers and quantum mechanical calculations. At pH 13 and an ozone concentration of approximately 150 mg L(-1) , periodate was completely regenerated from a 100 mm solution of iodate within 1 h at room temperature. A cyclic process of cellulose oxidation and subsequent regeneration of spent periodate with 90 % efficiency has been developed. So far, commercial applications of DAC have been hampered by difficulties in reusing the costly periodate. This work overcomes this hurdle and presents a highly efficient, clean, and low-cost protocol for the preparation of DAC with integrated periodate recycling, with the possibility of scaling the process up.

    On the basis of abnormal neuropsychological behavior in the open-field test after 2-week zinc deprivation, neurochemical response was examined in young mice fed a zinc-deficient diet for 2 weeks. Serum corticosterone concentration was markedly higher in zinc-deficient mice than in the control mice. Basal signals of intracellular calcium (fluo-4 FF) were also significantly more in hippocampal slices from zinc-deficient mice. These results suggest that basal Ca2+ levels in hippocampal cells are increased by zinc deficiency. On the other hand, Schaffer collateral long-term potentiation (LTP) was unaffected by zinc deficiency; the averaged fEPSP after tetanic stimulation was 162+/-8% of baseline value in the control and 172+/-22% in zinc-deficient mice. In the Morris water maze, there was also no significant difference in learning behavior for the hidden platform task between the control and zinc-deficient mice. The present study indicates that Schaffer collateral LTP associated with spatial cognition performance are unaffected by calcium dyshomeostasis in the hippocampus elicited by 2-week zinc deprivation, which may be linked to the increased serum corticosterone concentration.

    The orientation control of soft matter to create a large area single domain is one of the most exciting research topics in materials science. Recently, this effort has been extended to fabricate two- or three-dimensional structures for electro-optical applications. Here, we create periodic zigzag structures in liquid crystals (LCs) using a combination of surface treatment and thermal annealing. The LC molecules in the nematic (N) phase were initially guided by the alignment layer of rubbed polymers, which were quenched and subsequently annealed in the smectic A (SmA) phase to create periodic zigzag structures that represent modulated layer structures. Direct investigation of the zigzags was performed using microscopy and diffraction techniques, showing the alternately arranged focal conic domains (FCDs) formed. The resulting macroscopic periodic structures will be of interest in further studies of the physical properties of soft matters. PMID:26355381

    Objective To investigate whether proanthocyanidins (PA) is capable of improving dentin collagen’s biological stability through cross-linking within time periods that are clinically relevant. Materials and methods Demineralized dentin collagen slabs were treated with 3.75 wt% PA solution for 10 s, 1 min, 30 min, 60 min, 120 min, 360 min, and 720 min, respectively. The resultant cross-linked collagen samples were subject to digestion with 0.1% collagenase at 37 °C for 2 h, 6 h, 12 h, 24 h, 36 h, and 48 h. The percentage of weight loss after digestion was calculated to evaluate PA-treated collagen’s resistance toward enzymatic degradation. Fourier-Transformed Infrared (FTIR) spectroscopy was used to probe evidences of PA-collagen interactions after various periods of PA treatment. Results The collagenase digestion assay suggests that PA treatment as short as 10 s can enhance collagen’s resistance toward enzymatic challenge. The FTIR spectroscopy further verifies that PA is indeed incorporated into collagen regardless of treatment time, possibly via a mechanism involving the chemical interactions between PA and collagen. Significance This study confirmed that PA can effectively cross-link collagen and improve its biological stability in time periods as short as 10 s. The use of PA as a priming agent is therefore clinically feasible and is a promising approach to improving the durability of current dentin bonding systems. PMID:23434233

    A method of the formation of nanoporous structures in metallic materials by pulse-periodic laser treatment was developed. In this study, the multicomponent aluminum-iron brass was considered and the nanoporous structure across the entire cross section of the material with a thickness of 50 μm was formed. The method was implemented using a CO2 laser processing unit. The pulse-periodic laser treatment of the Cu-Zn-Al-Fe alloy with pulse frequency of 5 Hz has led to the formation of nanosized cavities due to accumulation of internal stresses during cyclic heating and cooling at high speeds. It was determined that the pores of a channel type with average widths of 80-100 nm are formed in the central region of the heat-affected zone during laser action with thermocycling. When implementing the chosen conditions of the pulse-periodic laser processing, the localness in depth and area of the physical processes occurring in the heat-affected zone is ensured, while maintaining the original properties of the material and the absence of significant deformations in the rest of the volume. This patented process is perspective for the production not only catalysts for chemical reactions, but for ultrafiltration and microfiltration membranes as well.

    Transfusion treatment is administered according to clinical and laboratory results, with ongoing patient assessments. Decisions on necessary measures to prevent any adverse and unexpected events and reactions are made on the basis ofhemovigilance and ongoing gathering and analysis of relevant data. Information about transfusion treatment at the Sestre milosrdnice University Hospital Center, Vinogradska site, was retrospectively collected for a period of twelve years (2001-2012). In that period, 14137.25 ± 1693.07 units of all blood products were used, where red blood cells (RBC) accounted for 67.34%, fresh frozen plasma (FFP) for 17.55%, and platelet concentrates (PC) for 14.32%. During the study period, the consumption of RBC was even, of FFP decreased by 45% and of PC increased by 58%. RBC transfusions were received by 10.43% of hospitalized patients, 1.46% of them during surgical procedures. Transfusions of all blood products were received by 14.63% of patients. We found 247 adverse reactions to all blood products. Febrile nonhemolytic and allergic reactions were quite equally represented, 49.5% each. As for other reactions (1%), one transfusion associated circulatory overload and one transfusion related acute lung injury were recorded. There were no fatal post-transfusion reactions.

    Studies of electroconvulsive therapy (ECT) have found an association between ictal electroencephalographic (EEG) measures and clinical outcome in depression. Such studies are lacking in schizophrenia. Consenting schizophrenia patients receiving ECT were assessed using the Brief Psychiatric Rating Scale (BPRS) before and 2 weeks after the start of ECT. The patients' seizure was monitored using EEG. In 26 patients, completely artifact-free EEG derived from the left frontal-pole (FP1) channel and electrocardiography (ECG) were available. The fractal dimension (FD) was computed to assess 4-s EEG epochs, and the maximal value from the earliest ECT session (2nd, 3rd or 4th) was used for analysis. There was a significant inverse correlation between the maximum FD and the total score following 6th ECT. An inverse Inverse correlation was also observed between the maximum FD and the total number of ECTs administered as well as the maximum heart rate (HR) and BPRS scores following 6th ECT. In patients with schizophrenia greater intensity of seizures (higher FD) during initial sessions of ECT is associated with better response at the end of 2 weeks. PMID:23261182

    A defensive mechanism against hypobaric hypoxia at high altitude is erythropoesis. Some authors point to the contribution of vitamin D to the regulation of this process. The aim of the present study was to assess the 25-hydroxycholecalciferol (25(OH)D) level and its associations with iron metabolic and inflammatory indices in participants of a 2-week mountaineering expedition. The study sample included 9 alpinists practicing recreational mountain climbing. Every 2 or 3 days they set up a different base between 3200 and 3616 m with the intention of climbing 4000 m peaks in the Mont Blanc massif. Before their departure for the mountains and 2 days after returning to the sea level anthropometric parameters, hematological parameters, serum levels of 25(OH)D and iron metabolic indices were measured in all the participants. The composition of the participants' diet was also evaluated. The comparative analysis showed a significant decrease in body mass, BMI values, total iron, and 25(OH)D concentrations (p<0.05). Also significant increases in unsaturated iron-binding capacity, hematocrit, and C-reactive protein concentrations (p<0.05) were found. It can be concluded that the 2-week climbing expedition contributed to the reduction of 25(OH)D levels and these changes were associated with modulation of immune processes. Moreover, the climbers' diet requires some serious modifications. PMID:26125641

    Tumor necrosis factor receptor-associated periodic syndrome (TRAPS) is a rare autosomal dominant disease included in the group of autoinflammatory syndromes. It is characterized by recurrent episodes of fever and inflammation in different regions of the body. The main clinical manifestations are myalgia, migratory erythematous rash, periorbital edema, and abdominal pain. The diagnosis is reached using gene analysis and prognosis depends on the appearance of amyloidosis secondary to the recurrent episodes of inflammation. Tumor necrosis factor inhibitors and corticosteroids are the most widely used treatments. In recent years, significant advances have been made in the diagnosis and treatment of TRAPS, thanks to a better understanding of its pathogenesis. Dermatologists must be aware that the skin manifestations of TRAPS are particularly important, as they are often diagnostic. PMID:23891452

    Background and Objectives The ideal line of osteosynthesis in mandibular angle fractures indicates that a plate might be placed either along or just below the external oblique ridge. Some authors believe that using one miniplate at this line at the mandibular angle region provides sufficient strength to stabilize the fracture but others imply a second plate is required. Such controversies exist in the use of maxillomandibular fixation (MMF). The intention of the present study was to compare efficiency and complications of using one miniplate with and without MMF in mandibular angle fractures. Methods and Materials Forty patients with facial trauma with mandibular angle fractures including displaced and unfavorable fractures were categorized into two groups of 20 persons. In all patients, one miniplate was placed on the external oblique ridge. In the first group, patients had light maxillomandibular elastic bands just after surgery but no rigid MMF. In the second group, patients had rigid MMF for 2 weeks after surgery. Patients were followed to evaluate complications and treatment efficiency. Conclusions Our study showed that use of a single miniplate in the external oblique ridge is a functionally stable treatment for all types of angle fractures (including displaced and unfavorable fractures) except comminuted and long oblique fractures, which were not included in our study. Use of postoperative MMF did not improve the results. PMID:24436745

    Objective. Thyrotoxic periodic paralysis (TPP) is a potentially life-threatening complication of Graves' disease (GD). The present study compared the long-term efficacy of antithyroid drugs (ATD), radioactive iodine (RAI), and surgery in GD/TPP. Methods. Sixteen patients with GD/TPP were followed over a 14-year period. ATD was generally prescribed upfront for 12–18 months before RAI or surgery was considered. Outcomes such as thyrotoxic or TPP relapses were compared between the three modalities. Results. Eight (50.0%) patients had ATD alone, 4 (25.0%) had RAI, and 4 (25.0%) had surgery as primary treatment. Despite being able to withdraw ATD in all 8 patients for 37.5 (22–247) months, all subsequently developed thyrotoxic relapses and 4 (50.0%) had ≥1 TPP relapses. Of the four patients who had RAI, two (50%) developed thyrotoxic relapse after 12 and 29 months, respectively, and two (50.0%) became hypothyroid. The median required RAI dose to render hypothyroidism was 550 (350–700) MBq. Of the 4 patients who underwent surgery, none developed relapses but all became hypothyroid. Conclusion. To minimize future relapses, more definitive primary treatment such as RAI or surgery is preferred over ATD alone. If RAI is chosen over surgery, a higher dose (>550 MBq) is recommended.

    Background The low prevalence of allergic disease in the rural tropics has been attributed to the protective effects of chronic helminth infections. There is concern that treatment-based control programmes for these parasites may lead to an increase in the prevalence of allergic diseases. Objective We measured the impact of 15–17 years of anthelmintic treatment with ivermectin on the prevalence of allergen skin test reactivity and allergic symptoms in school-age children. Methods The prevalence of allergen skin test reactivity, exercise-induced bronchospasm and allergic symptoms was compared between school-age children living in communities that had received community-based treatments with ivermectin (for onchocerciasis control) for a period of 15–17 years with those living in geographically adjacent communities that had received no ivermectin. Results The prevalence of allergen skin test reactivity was double in children living in treated communities compared with those in untreated communities (16.7% vs. 8.7%, adjusted OR 2.10, 95% CI 1.50–2.94, P<0.0001), and the effect was mediated partly by a reduced prevalence of Trichuris trichiura among treated children. Ivermectin treatments were associated with an increased prevalence of recent eczema symptoms (adjusted OR 2.24, 95% CI 1.05–4.78, P=0.04) but not symptoms of asthma or rhino-conjunctivitis. The effect on eczema symptoms was not associated with reductions in geohelminth infections. Conclusion Long-term periodic treatments with ivermectin were associated with an increased prevalence of allergen skin test reactivity. There was some evidence that treatment was associated with an increased prevalence of recent eczema symptoms but not those of asthma or rhino-conjunctivitis. Cite this as: P. Endara, M. Vaca, M. E.

    Bronchial asthma is a common disease in both the pediatric and adult populations, characterized by wide variations over short periods of time in resistance to airflow in intrapulmonary airways. A primary goal in the use of low- level laser therapy (LLLT) was the safe, effective and rapid palliation of symptoms owing to tracheal or bronchial obstruction. We have investigated the effects of LLLT comparatively with other modality trials in children's asthma. In the study were included 98 patients aged 10-18 years diagnosed with moderate or severe asthma, in attack- free period. The patients were divided into 3 groups. Group 1 received only laser therapy using extra meridian acupuncture points and scanning technique. Group 2 was treated only with inhaled Serevent 2 X 25 micrometers , two times daily, 3 months. Group 3 was tread with Theophylline retard in dosage of 15-mg/kg/12 h, 3 months. At the end of treatment we remarked a noticeable improvement of the clinical, functional and immunological characteristics at 83 percent of patients in group 1, comparatively with only 70 percent (group 2) and 53 percent (group 3). The LLLT had a very good action on bronchial patency , displayed an immunocorrecting action and is recommended in attack-free periods at children.

    The treatment of partial nefrectomies is usually performed under a warm ischemic period. Recently, various treatment modalities have become available to perform a partial nefrectomy without clamping off the blood circulation. We have studied three devices in laboratory setting, investigating the thermal and high speed imaging techniques in tissue models and consequently, applying the instruments in the clinic during open procedures especially looking at efficacy and blood loss. The continuous wave 2.0 micron laser of 70 W (Revolix, LISA laser) is used as a fiber delivered knife cutting through circulated tissue with controlled hemostasis for vessels up to 3 mm diameter. The 2 μm wavelength effectively vaporizes tissue water and coagulates the smaller vessels. The Hydro-Jet (ERBE, Germany) uses high pressure (20-80 bar) to ejects a water jet of 40 um diameter at high velocity (10-30 m/s). The parenchyma is resected while vessels are preserved. Consequently, the exposed vessels can be coagulated in a controlled way with minimal blood loss. The water jet showed to induce cavitation bubbles that resect the soft tissue from the matrix leaving the elastic microvessels intact. Various systems are based on bipolar RF technology. We are using the Habib device (Rita 1500X RF generator) to create a coagulation zone around the tumor. Subsequently, the tumor can be resected along the coagulation zone with minimal bleeding. The treatment modalities investigated, have their own advantages and, stand-alone or in combination, can facilitate laparoscopic partial nephrectomies without an ischemic period.

  17. Linear-scaling explicitly correlated treatment of solids: Periodic local MP2-F12 method

    2013-11-21

    Theory and implementation of the periodic local MP2-F12 method in the 3*A fixed-amplitude ansatz is presented. The method is formulated in the direct space, employing local representation for the occupied, virtual, and auxiliary orbitals in the form of Wannier functions (WFs), projected atomic orbitals (PAOs), and atom-centered Gaussian-type orbitals, respectively. Local approximations are introduced, restricting the list of the explicitly correlated pairs, as well as occupied, virtual, and auxiliary spaces in the strong orthogonality projector to the pair-specific domains on the basis of spatial proximity of respective orbitals. The 4-index two-electron integrals appearing in the formalism are approximated via the direct-space density fitting technique. In this procedure, the fitting orbital spaces are also restricted to local fit-domains surrounding the fitted densities. The formulation of the method and its implementation exploits the translational symmetry and the site-group symmetries of the WFs. Test calculations are performed on LiH crystal. The results show that the periodic LMP2-F12 method substantially accelerates basis set convergence of the total correlation energy, and even more so the correlation energy differences. The resulting energies are quite insensitive to the resolution-of-the-identity domain sizes and the quality of the auxiliary basis sets. The convergence with the orbital domain size is somewhat slower, but still acceptable. Moreover, inclusion of slightly more diffuse functions, than those usually used in the periodic calculations, improves the convergence of the LMP2-F12 correlation energy with respect to both the size of the PAO-domains and the quality of the orbital basis set. At the same time, the essentially diffuse atomic orbitals from standard molecular basis sets, commonly utilized in molecular MP2-F12 calculations, but problematic in the periodic context, are not necessary for LMP2-F12 treatment of crystals.

    The prevalence of anaemia during pregnancy and post partum is according to the literature and many years clinical experience high. In the submitted work we investigated the incidence of sideropenic anaemia in women during the first three months after a spontaneous delivery, changes of clinical and laboratory indicators of anaemia during this period and the possible effect exerted by administration of iron and iron plus folic acid resp. Ninety pregnant women in the 35th to 39th week of pregnancy were at random divided into three equally sized groups and the following were assessed: haemogram, indicators of iron reserves, serum concentrations of folic acid, vitamin B12, erythropoetin and soluble transferrin receptor, liver tests, total protein + electrophoresis, acute stage proteins. In the first group (T) the women were given, starting on the 4th day after delivery 1 tablet of Tardyferon per day for two months. To the second group (F) for an equal period 1 tablet of Tardyferon Fol per day was administered. Women in the control group (K) had no medication. In the investigation women with medium and severe pregnancy anaemia were not included nor women taking during pregnancy or previously iron preparations or those treated in the past by blood transfusion. After spontaneous delivery (women who had Caesarean section or forceps delivery were eliminated from the study) the women were subjected to the same examinations as before delivery. These examinations were made on the fourth day after delivery and then after monthly intervals for a period of three months. At the same time the subjective condition of the mothers was evaluated after delivery, focused on the development of symptoms typical for anaemia and the possible effect of administered treatment. The investigation was completed by 60 women. During treatment no allergic or other serious side-reactions to the administered drugs calling for discontinuation of treatment were recorded.

    Abnormal behavior in zinc deficiency and its cause are poorly understood. In the present paper, behavior in the forced swim test and neurochemical changes in the brain associated with its behavior were studied focused on abnormal corticosterone secretion in zinc deficiency. The effect of chronic corticosterone treatment was also studied. Immobility time in the forced swim test was increased in young rats fed a zinc-deficient diet for 2 weeks, as well as corticosterone (40mg/kg/dayx14 days)-treated control rats. The basal Ca(2+) levels in the hippocampus, which were determined by fluo-4FF, AM, were increased in both brain slices from zinc-deficient and corticosterone-treated rats. Serum glucose level was decreased in zinc deficiency and hippocampal glucose metabolism, which is determined by [(14)C]2-deoxyglucose uptake, was elevated. Hippocampal ATP level was not decreased, whereas, the concentrations of glutamate, GABA and glutamine in the hippocampus, unlike the whole brain, were decreased in zinc deficiency. However, the decrease in these amino acids was restored by adrenalectomy prior to zinc deficiency. These results suggest that glucose is insufficient for the synthesis of amino acids in the hippocampus of zinc-deficient rats. It is likely that the neurochemical and metabolic changes in the hippocampus, which may be associated with abnormal corticosterone secretion, is the base of abnormal behavior associated with neuropsychological symptoms in zinc deficiency.

    Background and purpose Fractures of the scaphoid are often not detected on initial plain radiographs. Conventional management of clinically suspected scaphoid fractures is cast immobilization for 2 weeks and then reassessment. Early MRI is a diagnostic alternative. We compared the cost and usefulness of the early MRI diagnostic strategy with that of conventional management. Patients and methods This prospective pseudo-randomized study included patients between 18 and 49 years of age who attended Bergen Accident and Emergency Department, Bergen, Norway during 1 year in 2009–2010, after sustaining an acute wrist trauma in the previous week and with a clinically suspected scaphoid fracture. 61 patients were investigated with acute MRI, while 63 patients received standard treatment as a control group. We used cost-minimization analysis to estimate the cost of the 2 patient groups. Results Concerning cost, there were no statistically significant differences in the total direct medical costs or in indirect costs between the groups. Concerning usefulness, patients in the MRI group without a fracture (n = 35) used a cast for fewer days (mean 1 day) than patients in the control group with no fractures (n = 52) (mean 14 days; p < 0.001). They had less than half the number of days on sick leave than patients in the control group (mean 7 days vs. 15 days; p = 0.002). Interpretation In a Norwegian setting, an early MRI was of value in patients with clinically suspected scaphoid fracture and normal plain radiographs. PMID:25409256

    Data from all 225 women operated on for ectopic pregnancy in 1992-1994 at Sahlgrenska University Hospital were collected and compared with three previous cross-sectional investigations from our hospital (1975-1979, 1981-1982 and 1986-1987) in order to evaluate the extent to which surgical treatment and post-operative complications have changed over a 20 year period. Laparoscopic surgery, which was not possible in the 1970s, was used in almost 85% of the ectopic pregnancies in 1992-1994. Conservative treatment was still the most frequently used technique. The complication rate was 1.2% in 1975-1979 when only laparotomies were carried out. After the introduction of laparoscopic surgery (1986-1987), the complication rate rose significantly (7.3%) and continued to increase even when this procedure was established as routine (14.2% in 1992-1994). Post-operative complications were most frequent after conservative laparoscopic surgery (24.4%) while there were no complications after laparotomies. In spite of increasing complication rates the frequency of patients in pre-shock, as well as the proportion of patients with heavy intra-abdominal bleeding and tubal rupture, decreased over time.

    Ivermectin is a safe, effective microfilaricide and microfilarial suppressant for Onchocerca volvulus; but in single doses of 100-200 micrograms/kg body weight it has no macrofilaricidal action. The present trial aimed to determine whether 6 doses of 100 micrograms/kg ivermectin, given at 2-week intervals, would kill the adult worms. Eighty-two nodules from 28 otherwise healthy adult male Liberian patients treated with this ivermectin schedule, and 102 nodules from a similar group of 25 control patients, were removed four months after the last dose of ivermectin. They were coded and assessed in a masked fashion either by routine histology or by examination of whole worms extracted from the nodules after collagenase digestion. The drug had no visible effect on adult male worms. More adult female worms were assessed as moribund or dead in the ivermectin-treated group than in the control group (for the collagenase digests P = 0.09; for the histological assessment P = 0.47). The data suggest that repeated dosage with ivermectin may lead to a slow attrition of some female worms and this possibility should be investigated in patients receiving regular doses every 3, 6 or 12 months as part of onchocerciasis control programmes.

EVIDENCE: MEDLINE was searched for articles published from 1966 to April 1998 that related to the prevention and treatment of obesity; additional articles were identified from the bibliographies of review articles and the listings of Current Contents. Selection criteria were used to limit the analysis to prospective studies with at least 2 years' follow-up. BENEFITS, HARM AND COSTS: Health benefits of weight reduction were evaluated in terms of alleviation of symptoms, improved management of obesity-related diseases and a reduction in major clinical outcomes. The health risk of weight-reduction methods were briefly evaluated in terms of increased mortality and morbidity. VALUES: The recommendations of this report reflect the commitment of the Canadian Task Force on Preventive Health Care to provide a structured, evidence-based appraisal of whether a manoeuvre should be part of a periodic health examination. RECOMMENDATIONS: (1) Prevention: There is insufficient evidence to recommend in favour of or against community-based obesity prevention programs; however, because of considerable health risks associated with obesity and the limited long-term effectiveness of weight-reduction methods, the prevention of obesity should be a high priority for health care providers (grade C recommendation). (2) Treatment: (a) For obese adults without obesity-related diseases, there is insufficient

    Small intestinal bacterial overgrowth (SIBO) can partly explain irritable bowel syndrome (IBS), and rifaximin has been observed to improve abdominal symptoms in nonconstipated IBS patients. However, there are few reports on the association of the rifaximin treatment periods with the results of a lactulose breath test (LBT). Therefore, we performed a retrospective review of patient charts to investigate the relation between the rifaximin treatment periods with LBT results in nonconstipated IBS patients. We also evaluated the time to achieve a symptomatic improvement in the IBS patients as compared to the changes in the LBT. We reviewed the charts for patients who showed IBS symptoms with documented positive results for LBT during their initial visit and who had a follow-up LBT after treatment with rifaximin. The LBT values were compared to the subjects' symptom scores. A total of 102 subjects had a follow-up LBT to assess LBT normalization. The subjects were divided into groups according to treatment periods of 4 weeks (n = 36), 8 weeks (n = 43), and 12 weeks (n = 23). The groups with a longer treatment exhibited an increase in the hydrogen gas value at 90 min and its sum during 90 min at the initial LBT. There were significant differences in hydrogen gas value at 90 min and in its sum during 90 min at the initial LBT between the groups treated for 4 and 12 weeks. The most significant treatment response was observed during the first 4 weeks for all treatment groups. Symptomatic improvement occurred earlier than LBT normalization in the treatment period over 4 weeks. The results indicate that different rifaximin treatment periods are needed in accordance with LBT levels to effectively eradicate SIBO. PMID:26028929

    Current treatment recommendations for narcolepsy suggest that modafinil should be used as a first-line treatment ahead of conventional stimulants or sodium oxybate. In this study, performed in a tertiary sleep disorders centre, treatment responses were examined following these recommendations, and the ability of sleep-stage sequencing of sleep-onset rapid eye movement periods in the multiple sleep latency test to predict treatment response. Over a 3.5-year period, 255 patients were retrospectively identified in the authors' database as patients diagnosed with narcolepsy, type 1 (with cataplexy) or type 2 (without) using clinical and polysomnographic criteria. Eligible patients were examined in detail, sleep study data were abstracted and sleep-stage sequencing of sleep-onset rapid eye movement periods were analysed. Response to treatment was graded utilizing an internally developed scale. Seventy-five patients were included (39% males). Forty (53%) were diagnosed with type 1 narcolepsy with a mean follow-up of 2.37 ± 1.35 years. Ninety-seven percent of the patients were initially started on modafinil, and overall 59% reported complete response on the last follow-up. Twenty-nine patients (39%) had the sequence of sleep stage 1 or wake to rapid eye movement in all of their sleep-onset rapid eye movement periods, with most of these diagnosed as narcolepsy type 1 (72%). The presence of this specific sleep-stage sequence in all sleep-onset rapid eye movement periods was associated with worse treatment response (P = 0.0023). Sleep-stage sequence analysis of sleep-onset rapid eye movement periods in the multiple sleep latency test may aid the prediction of treatment response in narcoleptics and provide a useful prognostic tool in clinical practice, above and beyond their classification as narcolepsy type 1 or 2.

    Objective To describe antidepressant (AD) use in the treatment of major depressive disorder during a period of economic crisis. Patients and methods This was a retrospective, observational study using population-based databases. Two periods were considered: 1) 2008–2009, precrisis, and 2) 2012–2013, economic crisis. Certain inclusion/exclusion criteria were taken into account for the study (initiation of AD treatment). Patients were followed up for 12 months. The main measures were use (defined daily doses), epidemiologic measures, strategies used and treatment persistence, referrals, and use of resources. Statistical significance was set at P<0.05. Results In the precrisis period, 3,662 patients were enrolled, and 5,722 were enrolled in the period of economic crisis. Average age was 58.8 years and 65.4% were women. Comparing the two periods, major depressive disorder prevalence was 5.4% vs 8.1%, P<0.001. During the period of economic crisis, AD use rose by 35.2% and drug expenditures decreased by 38.7%. Defined daily dose per patient per day was 10.0 mg vs 13.5 mg, respectively, P<0.001. At 12-month follow-up, the majority of patients (60.8%) discontinued the treatment or continued on the same medication as before, and in 23.3% a change of AD was made. Conclusion Primary health care professionals are highly involved in the management of the illness; in addition, during the period of economic crisis, patients with major depressive disorder showed higher rates of prevalence of the illness, with increased use of AD drugs.

    Kimchi, a traditional fermented food regularly consumed in Korea, contains various types of antimicrobial compounds. Among the tested compounds present in common spices used in Kimchi, quercetin showed the highest selectivity index against influenza A virus (IAV) H1N1. In this study, the effect of pretreatment and periodic treatment with quercetin against IAV in Madin-Darby canine kidney cells was observed. Compared to pretreatment, periodic treatment resulted in significantly higher cell viability but lower relative expression of the IAV PA gene and total apoptosis and cell death. To explain the mechanisms underlying the antiviral effects of quercetin treatment, a comparative proteomic analysis was performed in four samples (mock, quercetin-treated, IAV-infected, and quercetin-treated IAV-infected). Among the 220 proteins, 56 proteins were classified nonhierarchically into three clusters and were differentially modulated by quercetin treatment in IAV-infected cells. Post-translational modifications were identified in 68 proteins. In conclusion, periodic treatment with quercetin is effective in reducing IAV infection, and differentially regulates the expression of key proteins, including heat shock proteins, fibronectin 1, and prohibitin to reduce IAV replication.

    Objective: highlight the socioeconomic and environmental determining factors of long-term observance to antiretroviral treatments in developing countries. Method: The regularity of antiretroviral prescriptions renewal at the central pharmacy of the Yaounde Central Hospital (Cameroon) was measured through analysing the medical and pharmaceutical files of 230 patients over the 21 month start-up period. 99 patients were also interviewed during the last six months. The determining factors were analysed according to various socio-economic criteria, linked with the longitudinal study of treatment observance. Results: The huge price decrease of HIV treatments during the start-up period was conducive to an increase in new treatments by a factor 5.76. In this context of an exploding demand, the paper shows that observance is firstly dependent on quality information about illness and treatment protocols, while longer term adherence is partly dependent on financial capability, and includes the strong influence of living conditions and behaviours. Conclusion: The paper recommends the introduction of free treatment as an objective in national sector policies and the organisation of a long term following-up of patients. In the African context of poverty and actual decentralisation of healthcare, the question of the availability of human resources is profoundly enhanced. PMID:25214897

    Cyclin D2 knockout mice show decreased levels of endogenous dentate neurogenesis. We investigated whether transplanted dentate progenitor cells from wild-type mice respond in vivo to an enriched environment and whether they improve deficient dentate neurogenesis through a neurotrophic effect. Adult cyclin D2 knockout mice were transplanted with passaged adult progenitor cells and kept in an enriched environment or under standard housing conditions in isolation. After 1 week, animals living in an enriched environment underwent water maze testing. Progenitor cells grown on a laminin/poly-d-lysine monolayer expressed Sox2 and nestin and could be differentiated in vitro into neurons and astrocytes. After transplantation into the dentate gyrus, cells preferentially survived along the laminin-rich ependymal lining of the basal cistern or basal membrane of capillaries. A subpopulation of transplanted cells migrated into the interstitial space of the hippocampus and was not associated with laminin. Environmental enrichment led to a significant increase in the survival of transplanted progenitor cells on laminin in the dentate gyrus after 2 weeks. However, animals did not show an enhanced performance in the Morris water maze, and transplantation failed to exert a neurotrophic effect on endogenous neurogenesis after 2 weeks. However, a major limitation of the study is the short-term period of investigation, which may have been insufficient to capture functional effects. In conclusion, initial survival of transplanted neural progenitor cells was dependent on the presence of laminin and was significantly enhanced by environmental enrichment. Further studies are needed to address whether an enriched environment continues to promote graft survival over longer periods of time. PMID:25621922

    ABSTRACT  Alirocumab is a fully human monoclonal antibody to PCSK9. The ODYSSEY MONO study was the first alirocumab Phase III study to test a previously unused dose of 75 mg subcutaneously every 2 weeks in a population on no lipid-lowering therapy. A total of 103 patients were randomly assigned to alirocumab starting at 75 mg subcutaneously every 2 weeks or ezetimibe 10 mg per os every day with alirocumab dose uptitration at 12 weeks based on achieved LDL-cholesterol level at week 8 and followed to week 24. At the week-24 primary end point, the alirocumab intent-to-treat group showed a 47.2% (least square [LS] mean) reduction in LDL-cholesterol compared with a 15.6% (LS mean) reduction with ezetimibe (LS mean difference of 31.6%; p < 0.0001). Safety parameters and adverse events were similar between the two groups. PMID:25606700

    1. Our objective was to evaluate a possible pharmacokinetic interaction between zolpidem and fluvoxamine in healthy volunteers. 2. The study consisted of two periods: Period 1 (reference), when each volunteer received a single dose of 5 mg zolpidem; and Period 2 (test), when each volunteer received a single dose of 5 mg zolpidem and 100 mg fluvoxamine. Between the two periods, the subjects were treated for 6 days with a single daily dose of 100 mg fluvoxamine. 3. Pharmacokinetic parameters of zolpidem given in each treatment period were calculated using non-compartmental analysis and the data from two periods were compared to determine statistically significant differences. 4. In the two periods of treatments, the mean peak plasma concentrations (C(max)) were 56.4 ± 25.6 ng/mL (zolpidem alone) and 67.3 ± 25.8 ng/mL (zolpidem after pretreatment with fluvoxamine). The t(max), times taken to reach C(max), were 0.83 ± 0.44 and 1.26 ± 0.74 h, respectively, and the total areas under the curve (AUC(0-∞)) were 200.9 ± 116.8 and 512.0 ± 354.6 ng h/mL, respectively. The half-life of zolpidem was 2.24 ± 0.81 h when given alone and 4.99 ± 2.92 h after pretreatment with fluvoxamine. 5. Fluvoxamine interacts with zolpidem in healthy volunteers and increases its exposure by approximately 150%. The experimental data showed the pharmacokinetic interaction between zolpidem and fluvoxamine, and suggest that the observed interaction might be clinically significant, but its relevance has to be confirmed.

    Hydrogen can relieve tissue-damaging oxidative stress, inflammation and apoptosis. Injection of hydrogen-rich saline is an effective method for transporting molecular hydrogen. We hypothesized that hydrogen-rich saline would promote the repair of spinal cord injury induced by Allen's method in rats. At 0.5, 1, 2, 4, 8, 12 and 24 hours after injury, then once daily for 2 weeks, 0.25 mL/kg hydrogen-rich saline was infused into the subarachnoid space through a catheter. Results at 24 hours, 48 hours, 1 week and 2 weeks after injury showed that hydrogen-rich saline markedly reduced cell death, inflammatory cell infiltration, serum malondialdehyde content, and caspase-3 immunoreactivity, elevated serum superoxide dismutase activity and calcitonin gene-related peptide immunoreactivity, and improved motor function in the hindlimb. The present study confirms that hydrogen-rich saline injected within 2 weeks of injury effectively contributes to the repair of spinal cord injury in the acute stage. PMID:26199614

    Background Healthcare cost and reforms are at the forefront of international debates. One of the current discussion themes in oncology is whether and how patients’ life changes due to costs of cancer care. In Norway, the main part of the treatment costs is supported by general taxpayer revenues. Objectives The objective of this study was to clarify whether head and neck cancer patients (n=67) in northern Norway experienced financial health-related quality of life (HRQOL) deterioration due to costs associated with treatment. Design HRQOL was examined by the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 in the beginning and in the end of radiation treatment in patients treated at the University Hospital in Northern Norway. Changes in financial HRQOL were calculated and compared by paired sample T-tests. Multiple regression analyses were used to examine correlations among gender, marital status, age and treatment with or without additional chemotherapy and changes in the HRQOL domain of financial difficulties. Results The majority of score results at both time points were in the lower range (mean 15–25), indicating limited financial difficulties. We observed no statistically significant differences by gender, marital status and age. Increasing financial difficulties during treatment were reported by male patients and those younger than 65, that is, patients who were younger than retirement age. The largest effect was seen in singles. However, differences were not statistically significant. Conclusions During the initial phase of the disease trajectory, no significant increase in financial difficulties was found. This is in line with the aims of the Norwegian public healthcare model. However, long-term longitudinal studies should be performed, especially with regard to the trends we observed in single, male and younger patients. PMID:25623815

    The influence of glucocorticoids on the composition and mineral/organic content of the mandible in tested animals after recovery and healing phase was investigated in this work. The results of FTIR analysis demonstrated that bone tissue composition was changed after glucocorticoid treatment. The increase of calcium, magnesium, phosphorus content and mineral part of bones was statistically significant in recovery phase and in treatment phase that included calcitonin and thymus extract. Some changes also happened in the organic part of the matrix, as indicated by intensity changes for already present IR bands and the appearance of new IR bands in the region 3500-1300 cm-1.

    Cryscor is a periodic post-Hartree-Fock program based on local functions in direct space, i.e., Wannier functions and projected atomic orbitals. It uses atom centered Gaussians as basis functions. The Hartree-Fock reference, as well as symmetry information, is provided by the Crystal program. Cryscor presently features an efficient and parallel implementation of periodic local second order Møller-Plesset perturbation theory (MP2), which allows us to study 1D-, 2D- and 3D-periodic systems beyond 1000 basis functions per unit cell. Apart from the correlation energy also the MP2 density matrix, and from that the Compton profile, are available. Very recently, a new module for calculating excitonic band gaps at the uncorrelated Configuration-Interaction-Singles (CIS) level has been added. Other advancements include new extrapolation techniques for calculating surface adsorption on semi-infinite solids. In this paper the diverse features and recent advances of the present Cryscor version are illustrated by exemplary applications to various systems: the adsorption of an argon monolayer on the MgO (100) surface, the rolling energy of a boron nitride nanoscroll, the relative stability of different aluminosilicates, the inclusion energy of methane in methane-ice-clathrates, and the effect of electron correlation on charge and momentum density of α-quartz. Furthermore, we present some first tentative CIS results for excitonic band gaps of simple 3D-crystals, and their dependence on the diffuseness of the basis set. PMID:22334044

    Neonatal rat pups (7 days old) were intubated with either 50 mg/kg body weight or 100 mg/kg body weight of aqueous root extract of Clitoria ternatea (CTR) for 30 days. These rats were then subjected to open field, two compartment passive avoidance and spatial learning (T-Maze) tests (i) immediately after the treatment and (ii) 30 days after the treatment, along with age matched normal and saline control rats. Results showed no change in open field behaviour, but showed improved retention and spatial learning performance at both time points of behavioural tests, indicating the memory enhancing property of CTR which implicates a permanent change in the brain of CTR treated rats.

    Our experience is based on 147 patients with thoracic echinococcosis (TE) who underwent surgery. Of these, 131 (89.1%) patients had pulmonary TE, 3 (2.1%) had extra-pulmonary TE, and 13 (8.8%) had pulmohepatic TE Ninety-nine (67.3%) patients had uncomplicated TE, and 48 (32.7%) had complicated TE. All patients underwent surgery. In 129 (87.8%) patients, we performed cystectomy with capitonage and in 18 (12.2%) cases we performed a lung resection (lobectomy or segmentectomy). Postoperative complications occurred in 2 (1.4%) patients, and recurrence in 2 (1.4%) patients who previously had complicated TE. On admission, there was no evidence of allergic reactions in patients with complicated TE. The average time of postoperative treatment was 13 days. The results of surgical treatment were excellent. The conclusion reached is that a cystectomy with capitonage is the treatment of choice for pulmonary echinococcosis, while lung resection may be necessary if lung tissue has been destroyed by prolonged compression or infection.

    A general theoretical approach to pulsed Overhauser-type dynamic nuclear polarization (DNP) is presented. Dynamic nuclear polarization is a powerful method to create non-thermal polarization of nuclear spins, thereby enhancing their nuclear magnetic resonance signals. The theory presented can treat pulsed microwave irradiation of electron paramagnetic resonance transitions for periodic pulse sequences of general composition. Dynamic nuclear polarization enhancement is analyzed in detail as a function of the microwave pulse length for rectangular pulses and pulses with finite rise time. Characteristic oscillations of the DNP enhancement are found when the pulse-length is stepwise increased, originating from coherent motion of the electron spins driven by the pulses. Experimental low-field DNP data are in very good agreement with this theoretical approach.

    Cryopyrin-associated periodic syndrome (CAPS) encompasses a spectrum of three phenotypes of increasing severity. The syndrome is due to dominant mutations in NLRP3, which encodes a key component of the innate immunity that regulates the secretion of IL-1β. CAPS manifests as systemic inflammation, which compromises quality of life and leads to serious complications and handicap. Anti-IL-1 drugs have shown remarkable efficacy in treating CAPS symptoms and have significantly changed patients' lives. They have acceptable safety profiles but do have some differences. We review three drugs that are currently marketed for CAPS, give additional information for the practical use of these drugs, and provide some recommendations for management. PMID:26312542

    Our objective was to investigate effects of acute and 2-week administration of oral salbutamol on repeated sprint ability, exercise performance, and muscle strength in elite endurance athletes. Twenty male elite athletes [VO2max: 69.4 ± 1.8 (Mean ± SE) mL/min/kg], aged 25.9 ± 1.4 years, were included in a randomized, double-blinded and placebo-controlled parallel study. At baseline, after acute administration, and again after 2-week administration of the study drugs (8 mg salbutamol or placebo), subjects' maximal voluntary contraction (MVC) of m. quadriceps and isometric endurance of m. deltoideus were measured, followed by three repeated Wingate tests. Exercise performance at 110% of VO2max was determined on a bike ergometer. Acute administration of salbutamol increased peak power during first Wingate test by 4.1 ± 1.7% (P < 0.05). Two-week administration of salbutamol increased (P < 0.05) peak power during first and second Wingate test by 6.4 ± 2.0 and 4.2 ± 1.0%. Neither acute nor 2-week administration of salbutamol had any effect on MVC, exercise performance at 110% of VO2max or on isometric endurance. No differences were observed in the placebo group. In conclusion, salbutamol benefits athletes' sprint ability. Thus, the present study supports the restriction of oral salbutamol in competitive sports. PMID:25077918

    Strawberries are available throughout the year either from production in the field or from high and low tunnel culture. Diversity of production conditions results in new challenges in controlling diseases before and after harvest. Fungicides have traditionally been used to control these diseases; however, their limitations necessitate a search for new approaches. We found that UV-C irradiation of Botrytis cinerea, a major pathogen of strawberry, can effectively kill this fungus if a dark period follows the treatment. The inclusion of a 4-h dark period resulted in almost complete kill of B. cinerea conidia on agar media at a dose of 12.36 J/m2. The UV-C dose did not cause a reduction in photosynthesis in strawberry leaves or discoloration of sepals, even after exposing plants repeatedly (twice a week) for 7 weeks. Although irradiation of dry conidia of B. cinerea with this dose resulted in some survival, the conidia were not infective and not able to cause decay even when inoculated onto a highly susceptible mature apple fruit. Irradiation of strawberry pollen at 12.36 J/m2 did not affect pollen germination, tube growth and length in vitro, or germination and tube growth in the style of hand-pollinated emasculated strawberry flowers. No negative effect of the UV-C treatment was observed on fruit yield and quality in high tunnel culture. In the fruit and flower petal inoculation tests, the UV-C treatment was highly effective in reducing fruit decay and petal infection. This UV-C treatment with an exposure time of 60 s may be useful in controlling gray mold in tunnel production of strawberries and may also have the potential for use in intensive field and indoor production of other fruits and vegetables providing that a 4-h dark period follows the irradiation.

Patients were investigated before treatment and at 10 and 30 days; investigations included examination, points assessments of neurological disorders using the original Gusev-Skvortsova scale, neuropsychological tests using the MMSE scale, rheoencephalography, and electroencephalography. Analysis of changes in clinical features in patients treated with Actovegin during the acute period showed that Actovegin had clear positive effects both on general cerebral and on focal neurological symptoms. By the end of treatment, the extent of recovery of impaired functions, assessed in terms of total ischemic points and cognitive functions, was significantly greater in patients treated with Actovegin than in patients given piracetam. These data lead to the conclusion that Actovegin is effective in the treatment of patients with ischemic stroke. PMID:18802768

    Percutaneous transluminal angioplasty has been successfully used for the treatment of transplant renal artery stenosis (RAS). Cutting-balloon angioplasty (CBA) is being used as a second option in pressure-resistant stenosis. It is thought that CBA is less traumatic and therefore restenosis occurs less frequently than in conventional angioplasty. This case report describes the unusual use of a cutting balloon in transplant RAS as a first option in the early postoperative period. Long-term follow-up data are also presented.

    Abstract Objective: to analyze the meanings of leprosy for people treated during the sulfonic and multidrug therapy periods. Method: qualitative nature study based on the Vigotski's historical-cultural approach, which guided the production and analysis of data. It included eight respondents who have had leprosy and were submitted to sulfonic and multidrug therapy treatments. The participants are also members of the Movement for Reintegration of People Affected by Leprosy. Results: the meanings were organized into three meaning cores: spots on the body: something is out of order; leprosy or hanseniasis? and leprosy from the inclusion in the Movement for Reintegration of People Affected by Leprosy. Conclusion: the meanings of leprosy for people submitted to both regimens point to a complex construction thereof, indicating differences and similarities in both treatments. Health professionals may contribute to the change of the meanings, since these are socially constructed and the changes are continuous. PMID:26444163

    Intraosseous hemangiomas in the jaws are rare lesions and may lead to several complications. The authors present a case of a 12-year-old girl with a radiolucent periapical lesion between tooth 35 and 36 where nocturnal exsanguinating bleeding started to occur from periodontal sulcus during orthodontic treatment. Diagnosis of an intraosseous hemangioma in the mandible was based on positive needle aspiration for blood, computed tomography and arteriography. At first the family chose to only follow-up the lesion but episodes of nocturnal hemorrhage were becoming more frequent and a treatment was requested. Embolization and dental extraction were performed in order to treat the lesion. After a follow-up period of 17 years no more cases of hemorrhage occurred and lesion regressed. PMID:25307825

Dyscirculatory metabolic encephalopathy was revealed to be the main pathology with the etiological mechanism based on dyscirculatorhypoxic and metabolic disorders. Complexity of the revealed symptoms testified to an early organism aging in remote periods after exposure to low dose radiation. Pathogenetic schemes were developed for treatment of dyscirculatory encephalopathy in liquidators, which include drugs improving blood supply, antiaggregants, antioxidants and metabolites of the brains in various combinations. Taking into consideration that early appearance of vascular dyscirculatory disorders observed in liquidators is the sign of early aging of the organism, geroprotectors were added to treatment schemes.

    The changes triggered by sperm-induced activation of oocytes, which are required for normal oocyte development, can be mediated by other agents, thereby inducing the parthenogenesis. In this study, we exposed porcine oocytes to 1 mM Ca-EDTA, a metal-ion chelator, at various intervals during 48 hr of in vitro maturation to determine the optimum period of Ca-EDTA treatment for parthenogenetic activation. When the oocytes were cultured with or without Ca-EDTA from 36 hr (post-12), 24 hr (post-24), 12 hr (post-36) and 0 hr (post-48) after the start of maturation culture, the blastocyst formation rates were significantly higher (P<0.05) in the post-24, post-36 and post-48 groups (3.3%, 4.0% and 2.6%, respectively) than those in the control group without treatment (0%). Furthermore, when the oocytes were cultured with Ca-EDTA for 0 hr (control), 12 hr (pre-12), 24 hr (pre-24), 36 hr (pre-36) and 48 hr (pre-48) from the start of maturation culture, the oocytes formed blastocysts only in the pre-36 and pre-48 groups (0.4% or 0.8%, respectively). Pronuclei (<66.7%) were observed only when the periods of Ca-EDTA treatment were more than 12 hr during maturation culture. In the control group, no pronuclei were detected. Our findings demonstrate that porcine immature oocytes can be parthenogenetically activated by Ca-EDTA treatment for at least 24 hr to 36 hr during maturation culture, leading to pronucleus formation followed by the formation of blastocysts.

    The purpose of this study was to determine whether repeated heat load is closely related to circulating levels of free fatty acids (FFA) during repeated passive heat loading (PHL), defined as immersion of the lower body up to an umbilical level in hot water, 42 ± 0.5 °C (three times/week, 30 min/day) for 2 weeks. There were significant correlations between mean body temperature and FFA before and after repeated heat load ( p < 0.001, respectively), and the level of FFA was significantly higher after repeated heat load during PHL ( p < 0.01). The threshold of mean body temperature for lipolysis was lowered by repeated heat load and enhanced lipolysis during PHL. However, caution is needed for diabetic individuals.

    Background Recovery from fatigue is important in maintaining night workers' health. This study compared the course of self-reported recovery after 2-week 12-hour schedules consisting of either night shifts or swing shifts (i.e., 7 night shifts followed by 7 day shifts) to such schedules consisting of only day work. Methods Sixty-one male offshore employees—20 night workers, 16 swing shift workers, and 25 day workers—rated six questions on fatigue (sleep quality, feeling rested, physical and mental fatigue, and energy levels; scale 1–11) for 14 days after an offshore tour. After the two night-work schedules, differences on the 1st day (main effects) and differences during the follow-up (interaction effects) were compared to day work with generalized estimating equations analysis. Results After adjustment for confounders, significant main effects were found for sleep quality for night workers (1.41, 95% confidence interval 1.05–1.89) and swing shift workers (1.42, 95% confidence interval 1.03–1.94) when compared to day workers; their interaction terms were not statistically significant. For the remaining fatigue outcomes, no statistically significant main or interaction effects were found. Conclusion After 2-week 12-hour night and swing shifts, only the course for sleep quality differed from that of day work. Sleep quality was poorer for night and swing shift workers on the 1st day off and remained poorer for the 14-day follow-up. This showed that while working at night had no effect on feeling rested, tiredness, and energy levels, it had a relatively long-lasting effect on sleep quality. PMID:26929834

    To relieve respiratory problems such as apnea in newborns, caffeine citrate is the drug of choice because of its good tolerance and therapeutic index. However, its impact on the intestinal microbial ecosystem and on bacterial translocation in the neonatal period remains insufficiently investigated. Therefore, the objective of this study was to evaluate the effects of caffeine citrate on the establishment of the intestinal microflora and bacterial translocation in rats from birth to the 30th day of life. Newborn Wistar rats were divided into four groups of 14 animals, each subdivided into a control group receiving a placebo (12mL tap water/kg/day) and another treated with caffeine citrate (12mg/kg/day). The animals were nursed by their mothers and weighed daily. A group of 14 rats was killed at birth and after 10, 20, or 30 days of life. Organs in which translocation was assessed (liver, lungs, spleen, and kidneys) and various fragments of intestine (duodenum, jejunum, ileum, and colon) were surgically removed. The bacteriological analysis performed involved enumeration of the total microflora, staphylococci, enterobacteria, and lactobacilli. From the 10th day, caffeine was shown to significantly decrease the weight of treated animals as compared with controls (P<0.05). However, caffeine treatment did not drastically alter the kinetics of establishment of the intestinal microflora as only enterobacteria were found to be significantly lower in any intestinal segment of the treated group (P<0.05). Moreover, from the 20th day of life, caffeine citrate significantly downregulated bacterial translocation of both Gram-positive and -negative bacteria (P<0.05). This preliminary study on the effects of treatment with caffeine citrate may open opportunities in clinical pediatrics; the treatment will remain partially effective in preventing bacterial translocation in the neonatal period.

    The purpose of this research was to test for association between polymorphisms in the circadian clock-related gene PERIOD2 (PER2) and attrition in patients prone to withdrawal from a behavioral weight-reduction program based on the Mediterranean diet. A total of 454 overweight/obese participants (women=380, men=74), aged 20 to 65 years, who attended outpatient clinics specializing in obesity between January and December 2008, were studied. Anthropometric, biochemical, and dietary-intake variables were analyzed. Effectiveness of the program was assessed, and a questionnaire of barriers to weight loss was considered. Multivariate analysis and logistic regression models were performed. Results indicate that PER2 polymorphisms rs2304672C>G and rs4663302C>T were associated with abdominal obesity (P<0.05). Participants who withdrew from treatment were significantly more obese and had more barriers to lose weight (P<0.05). They also displayed a lower likelihood of planning eating in advance and experiencing stress with dieting than those who completed treatment. Frequency of rs4663307 minor allele was significantly greater in withdrawers than in those who successfully completed treatment (P<0.05). Logistic regression analysis showed that rs2304672 C>G minor allele carriers had a greater probability of dropping out, displaying extreme snacking, experiencing stress with dieting, eating when bored, and skipping breakfast than noncarriers. PER2 is implicated in attrition in weight-loss treatment and may modulate eating-behavior-related phenotypes. These findings could represent a step toward personalized health care and nutrition based on a combination of genotyping and psycho-behavioral characterization. PMID:20497782

    The rapid growth of observed exoplanets has revealed the existence of several distinct planetary populations in the mass-period diagram. Two of the most surprising are (1) the concentration of gas giants around 1 AU and (2) the accumulation of a large number of low-mass planets with tight orbits, also known as super-Earths and hot Neptunes. We have recently shown that protoplanetary disks have multiple planet traps that are characterized by orbital radii in the disks and halt rapid type I planetary migration. By coupling planet traps with the standard core accretion scenario, we showed that one can account for the positions of planets in the mass-period diagram. In this paper, we demonstrate quantitatively that most gas giants formed at planet traps tend to end up around 1 AU, with most of these being contributed by dead zones and ice lines. We also show that a large fraction of super-Earths and hot Neptunes are formed as 'failed' cores of gas giants—this population being constituted by comparable contributions from dead zone and heat transition traps. Our results are based on the evolution of forming planets in an ensemble of disks where we vary only the lifetimes of disks and their mass accretion rates onto the host star. We show that a statistical treatment of the evolution of a large population of planetary cores caught in planet traps accounts for the existence of three distinct exoplanetary populations—the hot Jupiters, the more massive planets around r = 1 AU, and the short-period super-Earths and hot Neptunes. There are very few populations that feed into the large orbital radii characteristic of the imaged Jovian planet, which agrees with recent surveys. Finally, we find that low-mass planets in tight orbits become the dominant planetary population for low-mass stars (M {sub *} ≤ 0.7 M {sub ☉}).

    This is the second part of a retrospective study of 400 root-fractured permanent incisors. In this article, the effect of various treatment procedures is analyzed. Treatment delay, i.e. treatment later than 24 h after injury, did not change the root fracture healing pattern, healing with hard tissue between fragments (HH1), interposition of bone and/or periodontal ligament (PDL) or pulp necrosis (NEC). When initial displacement did not exceed 1 mm, optimal repositioning appeared to significantly enhance both the likelihood of pulpal healing and hard tissue repair (HH1). Significant differences in healing were found among the different splinting techniques. The lowest frequency of healing was found with cap splints and the highest with fiberglass or Kevlar splints. The latter splinting procedure showed almost the same healing result as non-splinting. Comparison between non-splinting and splinting for non-displaced teeth was found to reveal no benefit from splinting. With respect to root fractures with displacement, too few cases were available for analysis. No beneficial effect of splinting periods greater than 4 weeks could be demonstrated. The administration of antibiotics had the paradoxical effect of promoting both HH1 and NEC. No explanation could be found. It was concluded that, optimal repositioning seems to favor healing. Furthermore, the chosen splinting method appears to be related to healing of root fractures, with a preference to pulp healing and healing fusion of fragments to a certain flexibility of the splint and possibly also non-traumatogenic splint application. Splinting for more than 4 weeks was not found to influence the healing pattern. A certain treatment delay (a few days) appears not to result in inferior healing. The role of antibiotics upon fracture healing is questionable. PMID:15245519

    Background The Sphingosine-1-phosphate (S1P) signaling pathway is known to influence pathophysiological processes within the brain and the synthetic S1P analog FTY720 has been shown to provide neuroprotection in experimental models of acute stroke. However, the effects of a manipulation of S1P signaling at later time points after experimental stroke have not yet been investigated. We examined whether a relatively late initiation of a FTY720 treatment has a positive effect on long-term neurological outcome with a focus on reactive astrogliosis, synapses and neurotrophic factors. Methods We induced photothrombotic stroke (PT) in adult C57BL/6J mice and allowed them to recover for three days. Starting on post-stroke day 3, mice were treated with FTY720 (1 mg/kg b.i.d.) for 5 days. Behavioral outcome was observed until day 31 after photothrombosis and periinfarct cortical tissue was analyzed using tandem mass-spectrometry, TaqMan®analysis and immunofluorescence. Results FTY720 treatment results in a significantly better functional outcome persisting up to day 31 after PT. This is accompanied by a significant decrease in reactive astrogliosis and larger post-synaptic densities as well as changes in the expression of vascular endothelial growth factor α (VEGF α). Within the periinfarct cortex, S1P is significantly increased compared to healthy brain tissue. Conclusion Besides its known neuroprotective effects in the acute phase of experimental stroke, the initiation of FTY720 treatment in the convalescence period has a positive impact on long-term functional outcome, probably mediated through reduced astrogliosis, a modulation in synaptic morphology and an increased expression of neurotrophic factors.

    Objective Program implementers have argued that the increasing availability of anti-retroviral therapy (ART) will reduce the stigma of HIV. We analyzed data from Uganda to assess how HIV-related stigma has changed during a period of ART expansion. Design Serial cross-sectional surveys. Methods We analyzed data from the Uganda AIDS Rural Treatment Outcomes (UARTO) study during 2007-2012 to estimate trends in internalized stigma among people living with HIV (PLHIV) at the time of treatment initiation. We analyzed data from the Uganda Demographic and Health Surveys (DHS) from 2006 and 2011 to estimate trends in stigmatizing attitudes and anticipated stigma in the general population. We fitted regression models adjusted for socio-demographic characteristics, with year of data collection as the primary explanatory variable. Results We estimated an upward trend in internalized stigma among PLHIV presenting for treatment initiation (adjusted b=0.18; 95% CI, 0.06 to 0.30). In the general population, the odds of reporting anticipated stigma were greater in 2011 compared to 2006 (adjusted OR=1.80; 95% CI, 1.51 to 2.13), despite an apparent decline in stigmatizing attitudes (adjusted OR=0.62; 95% CI, 0.52 to 0.74). Conclusions Internalized stigma has increased over time among PLHIV in the setting of worsening anticipated stigma in the general population. Further study is needed to better understand the reasons for increasing HIV-related stigma in Uganda and its impact on HIV prevention efforts. PMID:25268886

    : Although numerous papers have emphasized the importance of accurate needle positioning in lumbar discography, no concrete evidence is available to support this contention, and no study has evaluated the image consistency of discography as influenced by this factor. By observing the consistency of two images in relation to needle tip position we aimed to clarify the importance of needle positioning in discography. One hundred and ninety-two patients (324 discs) receiving steroid intradiscal therapy in whom discography of the same disc was performed twice at a 2-week interval and in whom the needle tip position was within the acceptable range (as defined by us) were studied. The patients were divided into two groups: in group G, in whom the needle tip was within a limited range on both discograms, and group P, in whom the needle tip was in this range on only one discogram. Image consistency was compared roentgenographically in the two groups. The consistent image rate for the total number of discs was 48.5%, being significantly higher in group G (53.2%) than in group P (39.0%). The rates were lower in the nucleus pulposus and the posterior portion of the disc than in the other disc areas, but were significantly higher in group G (85. 4% and 75.0%, respectively, for these two areas). The necessity for accurate needle tip positioning was proved roentgenographically. PMID:9732558

    The practice of an infectious diseases (ID) physician is evolving. A contemporary understanding of the frequency and variety of patients and syndromes seen by ID services has implications for training, service development and setting research priorities. We performed a 2-week prospective survey of formal ID physician activities related to direct inpatient care, encompassing 53 hospitals throughout Australia, New Zealand and Singapore, and documented 1722 inpatient interactions. Infections involving the skin and soft tissue, respiratory tract and bone/joints together accounted for 49% of all consultations. Suspected/confirmed pathogens were primarily bacterial (60%), rather than viral (6%), fungal (4%), mycobacterial (2%) or parasitic (1%). Staphylococcus aureus was implicated in 409 (24%) episodes, approximately four times more frequently than the next most common pathogen. The frequency of healthcare-related infections (35%), immunosuppression (21%), diabetes mellitus (19%), prosthesis-related infections (13%), multiresistant pathogens (13%) and non-infectious diagnoses (9%) was high, although consultation characteristics varied between geographical settings and hospital types. Our study highlights the diversity of inpatient-related ID activities and should direct future teaching and research. ID physicians' ability to offer beneficial consultative advice requires broad understanding of, and ability to interact with, a wide range of referring specialities. PMID:24494809

    Background The Cryopyrin-Associated Periodic Syndromes (CAPS) are a group of rare hereditary autoinflammatory diseases and encompass Familial Cold Autoinflammatory Syndrome (FCAS), Muckle-Wells Syndrome (MWS), and Neonatal Onset Multisystem Inflammatory Disease (NOMID). Canakinumab is a monoclonal antibody directed against IL-1 beta and approved for CAPS patients but requires post-approval monitoring due to low and short exposures during the licensing process. Creative approaches to observational methodology are needed, harnessing novel registry strategies to ensure Health Care Provider reporting and patient monitoring. Methods A web-based registry was set up to collect information on long-term safety and effectiveness of canakinumab for CAPS. Results Starting in November 2009, this registry enrolled 241 patients in 43 centers and 13 countries by December 31, 2012. One-third of the enrolled population was aged < 18; the overall population is evenly divided by gender. Enrolment is ongoing for children. Conclusions Innovative therapies in orphan diseases require post-approval structures to enable in depth understanding of safety and natural history of disease. The rarity and distribution of such diseases and unpredictability of treatment require innovative methods for enrolment and follow-up. Broad international practice-based recruitment and web-based data collection are practical. PMID:24016338

    Onions of "Dorata di Parma" variety were exposed to 10 Krads of Co60 gamma irradiation in 5, 10, 20, 40, and 80 minutes in December, 1975 and then stored in the cold storage (10 +/- 1 degree C; R.H. 65-70%) and at the room temperature (15-20 degrees C; R.H. 40-70%) for 3 months, to study the influence of dose-rate and post-harvest period of treatment. Average number of buds sprouted in each onion bulb under cold storage condition ranged from 2-3, while this number was found to increase to 3-4 under ambient storage conditions. Although no effect of either irradiation or dose rate was observed when onions were irradiated after the break of their dormancy, however, a significant slowing down effect of irradiation could be observed as far as the rate of growth of sprouts was concerned. Weight loss was also reduced significantly in the irradiated onions as compared with controls. PMID:1037423

    Commencing some training sessions with reduced carbohydrate (CHO) availability has been shown to enhance skeletal muscle adaptations, but the effect on exercise performance is less clear. We examined whether restricting CHO intake between twice daily sessions of high-intensity interval training (HIIT) augments improvements in exercise performance and mitochondrial content. Eighteen active but not highly trained subjects (peak oxygen uptake [VO2peak] = 44 ± 9 ml/kg/min), matched for age, sex, and fitness, were randomly allocated to two groups. On each of 6 days over 2 weeks, subjects completed two training sessions, each consisting of 5 × 4-min cycling intervals (60% of peak power), interspersed by 2 min of recovery. Subjects ingested either 195 g of CHO (HI-HI group: ~2.3 g/kg) or 17 g of CHO (HI-LO group: ~0.3 g/kg) during the 3-hr period between sessions. The training-induced improvement in 250-kJ time trial performance was greater (p = .02) in the HI-LO group (211 ± 66 W to 244 ± 75 W) compared with the HI-HI group (203 ± 53 W to 219 ± 60 W); however, the increases in mitochondrial content was similar between groups, as reflected by similar increases in citrate synthase maximal activity, citrate synthase protein content and cytochrome c oxidase subunit IV protein content (p > .05 for interaction terms). This is the first study to show that a short-term "train low, compete high" intervention can improve whole-body exercise capacity. Further research is needed to determine whether this type of manipulation can also enhance performance in highly-trained subjects. PMID:25811132

Exclusive enteral nutrition (EEN) is a common anti-inflammatory treatment in children with Crohn's disease in the European countries, and the mechanism is most likely linked to changes in the intestinal microbiome. In the present study, EEN was given in two treatment periods several months apart to a patient with very severe, disabling juvenile idiopathic arthritis (JIA), with a remarkable clinical response as the result. The aim of the present study was to study how the EEN treatment influenced the microbiome and metabolome of this patient. Fecal samples from before, during, and between treatments with EEN were studied. The microbiome was analyzed by sequencing of 16S rRNA amplicons using Illumina MiSeq, and the metabolome was analyzed using nuclear magnetic resonance. The microbiome changed markedly from treatment with EEN, with a strong reduction of the Bacteroidetes phylum. Metabolic profiles showed clear differences before, during, and between treatment with EEN, where butyrate, propionate, and acetate followed a cyclic pattern with the lowest levels at the end of each treatment period. This patient with JIA showed remarkable clinical improvement after EEN treatment, and we found corresponding changes in both the fecal microbiome and the metabolome. Further studies are needed to explore the pathophysiological role of the intestinal canal in children with JIA. PMID:27021336

    Background & Aims We evaluated the relationship between the early clinical response after 2 weeks of sorafenib therapy and the outcomes and anti-tumor response in patients with advanced hepatocellular carcinoma. Methods Fifty-seven patients who had intrahepatic hypervascular hepatocellular carcinoma and Child-Pugh (CP) class A disease at baseline were enrolled in this prospective, multicenter, observational, non-interventional study. As an early clinical response after 2 weeks of sorafenib therapy, changes in intra-tumor blood flow on contrast-enhanced computed tomography (CE-CT), alpha-fetoprotein (AFP) levels, and remnant liver function were investigated. Results After 2 weeks of sorafenib therapy, there were 26 patients (45.6%) without disappearance of arterial tumor enhancement on CE-CT, 15 patients (26.3%) with an AFP ratio of >1.2, and seven patients (12.3%) with two or more increments in the CP score. Multivariate analysis showed that the absence of disappearance of arterial tumor enhancement on CE-CT, AFP ratio of >1.2, and two or more increments in the CP score after 2 weeks of sorafenib therapy were significant and independent predictors of worse survival. Upon scoring these three variables as "poor prognostic factors", patients with poor prognostic score 4, 3 or 2 (n = 17) had significantly worse outcomes and a significantly higher progressive disease (PD) rate based on modified Response Evaluation Criteria in Solid Tumors at 6 weeks after sorafenib therapy than those with poor prognostic score 1 or 0 (n = 40) (median overall survival: 194 days vs. 378 days; p = 0.0010, PD rate: 70.6% vs. 20.0%; p = 0.0003, respectively). Conclusions Changes in intra-tumor blood flow on CE-CT, AFP levels, and remnant liver function after 2 weeks of sorafenib therapy may be useful for predicting the outcomes and anti-tumor response to sorafenib in patients with advanced hepatocellular carcinoma.

    This paper describes an individual who was diagnosed with obsessive-compulsive disorder (OCD) and body dysmorphic disorder (BDD) at age 17 when education was discontinued. By age 19, he was housebound without social contacts except for parents. Adequate trials of three selective serotonin reuptake inhibitors, two with atypical neuroleptics, were ineffective. Major exacerbations following ear infections involving Group A beta-hemolytic streptococcus at ages 19 and 20 led to intravenous immune globulin therapy, which was also ineffective. At age 22, another severe exacerbation followed antibiotic treatment for H. pylori. This led to a hypothesis that postulates deficient signal transduction by the N-methyl-D-aspartate receptor (NMDAR). Treatment with glycine, an NMDAR coagonist, over 5 years led to robust reduction of OCD/BDD signs and symptoms except for partial relapses during treatment cessation. Education and social life were resumed and evidence suggests improved cognition. Our findings motivate further study of glycine treatment of OCD and BDD. PMID:20182547

    Background: There were few studies on the relation between changes in libido and incidence of stroke recurrence. The aim of this study was to investigate the relationship between libido decrease at 2 weeks after stroke and recurrent stroke at 1-year. Methods: It is a multi-centered, prospective cohort study. The 14th item of the Hamilton Depression Rating Scale-17 was used to evaluate changes of libido in poststroke patients at 2 weeks. Stroke recurrence was defined as an aggravation of former neurological functional deficit, new local or overall symptoms, or stroke diagnosed at re-admission. Results: Among 2341 enrolled patients, 1757 patients had completed follow-up data, 533 (30.34%) patients had decreased libido at 2 weeks, and 166 (9.45%) patients had recurrent stroke at 1-year. Multivariate logistic regression analysis showed that, compared with patients with normal libido, the odds ratio (OR) of recurrent stroke in patients with decreased libido was reduced by 41% (OR = 0.59, 95% confidence interval [CI]: 0.40–0.87). The correlation was more prominent among male patients (OR = 0.52, 95% CI: 0.31–0.85) and patients of ≥60 years of age (OR = 0.57, 95% CI: 0.35–0.93). Conclusions: One out of three stroke patients in mainland China has decreased libido at 2 weeks after stroke. Decreased libido is a protective factor for stroke recurrence at 1-year, which is more prominent among older male patients. PMID:25963346

    Although canine skin models are already available as either monocellular or organotypic cultures, they only partly recapitulate normal skin morphological features and function. The objective of this study was to establish a canine serum-free skin organ culture model and verify whether dexamethasone could rescue epidermal growth factor-induced changes. The study of morphological changes as a response to pharmacological substances may indeed help to investigate skin physiology and pathology. Normal skin was obtained from five client-owned dogs subjected to surgical procedures unrelated to dermatological conditions. Two experimental designs were performed: (i) two-week viability of the skin culture; (ii) dexamethasone (DMS) inhibition of epidermal growth factor (EGF)-induced effects. Serum-free submerged organ cultures were established in Williams' E medium supplemented with penicillin-streptomycin, insulin, hydrocortisone and l-glutamine. General morphological features of skin anatomical structures were well maintained up to day 14, scattered pyknotic nuclei were visible in the epidermis from day 7. Normal keratinocyte differentiation was confirmed by cytokeratin (K) 10, K14 and loricrin immunostaining. Epidermal thickness did not decrease throughout the study. A decrease in keratinocyte proliferation was observed at day 7 and 14. Treatment with EGF induced both keratinocyte proliferation and thickening of the epidermis; both responses were counteracted by DMS. Treatment with EGF increased the length of epithelial tongues at the edge of the skin explants; this effect was further enhanced by DMS supplementation. Our findings demonstrate the potential use of a full-thickness canine skin organ culture model for the study of skin physiology and pharmacological response to exogenous compounds, especially in the field of re-epithelialisation and keratinization disorders.

    Purpose Corneal graft rejection is the most common reason for the failure of an allograft corneal transplant. We undertook this study to identify and compare risk factors and treatment outcomes for early and late corneal graft rejections after optical penetrating keratoplasty. Methods A retrospective case file analysis of 880 primary penetrating keratoplasties was performed at a tertiary ophthalmic care centre. Patients were divided into early rejectors (rejection episode within 6 months postoperatively) and late rejectors (rejection episode after 6 months postoperatively). Main parameters evaluated were demographics, preoperative diagnosis and clinical signs, donor tissue details, surgical technique, details of rejection episode, treatment, and outcome information. Results A total of 156 patients with rejection episodes were identified. Of these, 42 (26.9%) patients experienced early rejection episodes and 114 (73.1%) patients experienced late rejection episodes. Preoperative donor and recipient characteristics, surgical technique, and clinical presentation of graft rejection were found to be similar between both groups after a Bonferroni correction was applied (P>0.005). Treatment outcomes of graft rejections were not significantly different (P=0.46) between early and late rejectors, with 83% of patients responding to rejection treatment (80% early rejectors; 85% late rejectors). Conclusion Patients with early and late graft rejection have similar characteristics and both groups respond to treatment equally. PMID:22344190

    Neurodegenerative disorders such as Alzheimer's disease (AD) are characterized by the loss of neurotrophic factors, and experimental therapeutical approaches to AD have investigated the efficacy of replacing or augmenting neurotrophic factor activity. Cerebrolysin, a peptide mixture with neurotrophic-like effects, has been shown to improve cognition in patients with AD and to reduce synaptic and behavioral deficits in transgenic (tg) mice overexpressing the amyloid precursor protein (APP). However, it is unclear how long-lasting the beneficial effects of Cerebrolysin are and whether or not behavioral and neuropathological alterations will reappear following treatment interruption. The objective of the present study was to investigate the consequences of interrupting Cerebrolysin treatment (washout effect) 3 and 6 months after the completion of a 3-month treatment period in APP tg mice. We demonstrate that, in APP tg mice, Cerebrolysin-induced amelioration of memory deficits in the water maze and reduction of neurodegenerative pathology persist for 3 months after treatment interruption; however, these effects dissipate 6 months following treatment termination. Immunohistochemical analysis demonstrated that the decrease in neocortical and hippocampal amyloid plaque load observed in Cerebrolysin-treated APP tg mice immediately after treatment was no longer apparent at 3 months after treatment interruption, indicating that the beneficial effects of Cerebrolysin at this time point were independent of its effect on amyloid-β deposition. In conclusion, the results demonstrate that the effects of Cerebrolysin persist for a significant period of time following treatment termination and suggest that this prolonged effect may involve the neurotrophic factor-like activity of Cerebrolysin.

    The presence of anovulatory haemorrhagic follicles during the oestrous cycle of mares causes financial impacts, slowing conception and increasing the number of services per pregnancy. Non-steroidal anti-inflammatory drugs (NSAIDs) such as meloxicam and phenylbutazone are used in the treatment of several disorders in mares, and these drugs can impair the formation of prostaglandins (PGs) and consequently interfere with reproductive activity. This study aimed to evaluate the effects of treatment with NSAIDs on the development of pre-ovulatory follicles in mares. In total, 11 mares were studied over three consecutive oestrous cycles, and gynaecological and ultrasound examinations were performed every 12 h. When 32-mm-diameter follicles were detected, 1 mg of deslorelin was administered to induce ovulation. The first cycle was used as a control, and the mares received only a dose of deslorelin. In the subsequent cycles, in addition to receiving the same dose of deslorelin, each mare was treated with NSAIDs. In the second cycle, 4.4 mg/kg of phenylbutazone was administered, and in the third cycle, 0.6 mg/kg of meloxicam was administered once a day until ovulation or the beginning of follicular haemorrhage. All of the mares ovulated between 36 and 48 h after the induction in the control cycle. In the meloxicam cycle, 10 mares (92%) did not ovulate, while in the phenylbutazone cycle, nine mares (83%) did not ovulate. In both treatments, intrafollicular hyperechoic spots indicative of haemorrhagic follicles were observed on ultrasound. Thus, our results suggested that treatment with meloxicam and phenylbutazone at therapeutic doses induced intrafollicular haemorrhage and luteinization of anovulatory follicles. PMID:26280558

    Purpose: To evaluate the demographics and management outcomes of strabismus surgery in patients with third cranial nerve palsy. Methods: This retrospective study includes subjects with third cranial nerve palsy. We evaluated age, sex, laterality, severity of involvement, etiology, frequency of clinical findings, and types and results of treatments. Results: 52 patients including 29 male and 23 female subjects with mean age of 21.1±15.5 years were studied between January 1999 and January 2009. Etiologies of third nerve palsy included congenital in 16 (30.8%), trauma in 26 (50%) and other causes in 10 (19.2%) patients. In 24 patients (46.2%), the palsy was complete. The most common type of strabismus was exotropia associated with hypotropia (40%). Medical treatment was used in 25 (48%) and surgical treatment in 46 (88.4%) subjects. One time strabismus surgery was performed in 30 (65.2%), 2 times in 11 (24%) and 3 times in 5 (10.8%) subjects. The most common operation was large horizontal recession and resection in 78.2% of cases. Mean horizontal deviation in primary position was 66±29 prism diopters (PD) before surgery decreasing to 21±19, 13±12 and 6±8 PD after first, second and third surgery, respectively. Corresponding figures for mean vertical deviation were 13±15, 7±12, 4±6 and 1±2 PD, respectively. Abnormal head posture was 10-30° in 11 (21.1%) cases before treatment which completely resolved after surgery. Conclusion: Surgical management of strabismus in patients with third nerve palsy is difficult and challenging, however the majority of patients achieve ideal results with appropriate and stepwise surgical plans.

    Background: Cannabis continues to be the most commonly used illicit psychoactive substance globally. The National Survey in India conducted in the year 2004 also reported it to be the most commonly used illicit substance in the country. Furthermore, it was reported to be the second most commonly used psychoactive substance by the treatment seekers at de-addiction centers in the country. Objectives: To assess time trends of cannabis use among treatment-seeking individuals at government de-addiction centers across India over a period of 7 years. Materials and Methods: The study utilized data collected through Drug Abuse Monitoring System across India. The data of treatment seekers from de-addiction centers established under the Drug De-addiction Program, Ministry of Health and Family Welfare, Government of India and supported by the Ministry of Social Justice and Empowerment, Government of India (122 in number) across the country were analyzed. Results: A total of 107,469 individuals sought treatment from government de-addiction centers over the 7 years (2007–2013) period. With the exception of an aberration for the year 2012, there has been a steady decline in the proportion of treatment seekers who are not current cannabis users. A significantly greater proportion (Chi-square: 586.30, df: 1, P < 0.001) of individuals with current cannabis use alone or along with tobacco (20.4%) tend to have a co-morbid psychiatric disorder as compared to treatment seekers with current use of substances other than cannabis (6.1%). Conclusions: It is important to focus on cannabis in clinical service delivery and research in the country.

    Follicular mucinosis (FM) and folliculotropic mycosis fungoides (MF) are rare in children, and data regarding long-term outcomes are limited. We sought to describe clinical and histopathologic findings of children with FM with and without MF, as well as treatments administered and clinical outcomes. We conducted a retrospective chart review of patients younger than 22 years (at time of diagnosis) with a biopsy demonstrating FM who were seen in the Dermatology Department at the Mayo Clinic from September 1, 1999, to September 1, 2010. Eleven patients (six male, five female) ages 11 to 19 years at the time of diagnosis met the inclusion criteria. Follow-up data were available for 10 patients, with a mean duration of 4.9 years. The head, neck, and extremities were the most common sites of involvement, and lesions were follicular-based papules (18%), scaly alopecic patches and plaques (45%), or a combination of the two (36%). Overall, three patients were confirmed to have MF. T-cell receptor gene rearrangement demonstrated clonality in two cases and was equivocal in one case. Treatments included topical corticosteroids, topical retinoids, oral minocycline, and, in patients with MF, ultraviolet light and topical bexarotene. Lesions resolved completely in seven patients, partially in one, and not at all in two (no follow-up data on one patient). Of the three patients with MF, two had complete resolution, and one has intermittent flares. To our knowledge, no patients developed other lymphoproliferative disorders. FM in children is rare. A histopathologic diagnosis of FM does not equate to folliculotropic MF in all cases. Most patients responded to treatment with topical steroids, topical retinoids, or phototherapy. In our series of patients, the disease ran a benign course. PMID:23278316

    The ab initio calculation of charged defect properties in solids is not straightforward because of the delicate interplay between the long-range Coulomb interaction and the periodic boundary conditions. We derive the Projector Augmented-Wave (PAW) energy and hamiltonian with a special care on the potentials from Coulomb interaction. By explicitly treating the background compensation charge, we find a new term in the total energy of charged cells and in the potential. We show that this background term is needed to accurately reproduce all-electron calculations of the formation energy of a charged defect. In particular, the previous PAW expressions were spuriously sensitive to the pseudization conditions and this artifact is removed by the background term. This PAW derivation also provides insights into the norm-conserving pseudopotential framework. We propose then an alternative definition for the total energy of charged cells and for the potential within this framework.

    Circadian rhythms in cardiac function are apparent in e.g., blood pressure, heart rate, and acute adverse cardiac events. A circadian clock in heart tissue has been identified, but entrainment pathways of this clock are still unclear. We cultured tissues of mice carrying bioluminescence reporters of the core clock genes, period 1 or 2 (per1luc or PER2LUC) and compared in vitro responses of atrium to treatment with medium and a synthetic glucocorticoid (dexamethasone [DEX]) to that of the suprachiasmatic nucleus (SCN) and liver. We observed that PER2LUC, but not per1luc is rhythmic in atrial tissue, while both per1luc and PER2LUC exhibit rhythmicity in other cultured tissues. In contrast to the SCN and liver, both per1luc and PER2LUC bioluminescence amplitudes were increased in response to DEX treatment, and the PER2LUC amplitude response was dependent on the time of treatment. Large phase-shift responses to both medium and DEX treatments were observed in the atrium, and phase responses to medium treatment were not attributed to serum content but the treatment procedure itself. The phase-response curves of atrium to both DEX and medium treatments were found to be different to the liver. Moreover, the time of day of the culturing procedure itself influenced the phase of the circadian clock in each of the cultured tissues, but the magnitude of this response was uniquely large in atrial tissue. The current data describe novel entrainment signals for the atrial circadian clock and specifically highlight entrainment by mechanical treatment, an intriguing observation considering the mechanical nature of cardiac tissue.

    Nontyphoid Salmonella (NTS) can cause invasive diseases in the elderly. Notably, the most feared complication of NTS bacteremia is endovascular infection. The risk factors for infected aortic aneurysm include old age and atherosclerosis. Extended use of antimicrobial therapy (> 2 weeks) for NTS bacteremia should be considered for those who demonstrate the risk factors for endovascular infection, even when a metastatic focus is clinically elusive. Herein, we report the case of a 75-year-old patient with diabetes mellitus, hypertension, chronic kidney disease, and myocardial infarction who died of an infected aortic aneurysm despite 3 weeks of antibiotic therapy that was administered to treat the initial NTS bacteremia.

    The fundamental issue of the region of period formaton in a degenerate star is examined, with special attention given to the treatment of the Brunt-Vaisala frequency. It is shown that, in order to obtain reliable numerical results in degenerate stellar models, the Brunt-Vaisala frequency must be appropriately transformed, because it is defined in terms of a difference between two numbers which become nearly equal in highly degenerate matter, causing serious numerical problems and systematic errors. An alternative expression is derived, which is valid for multicomponent nonideal partially degenerate and partially ionized plasmas such as those encountered in white dwarf envelopes. This expression is used to compute the period structure of the same white dwarf considered by Pesnell (1987). It is shown that the implicit numerical differencing used in the Lagrangian pulsation code of Pesnell leads to very serious difficulties when used with models of degenerate stars.

    ABSTRACT Internal hernia in avian species is very rare. A necropsy of a 2-week-old SPF White Leghorn chicken revealed that a loop of the duodenum and part of the pancreas (4 × 2 × 1 cm) was protruding through the abnormal foramen (2.5 cm in diameter) in the right posthepatic septum into the right ventral hepatic peritoneal cavity. The herniated loop was located underneath the ventral hepatic surface, leaving a groove on the right hepatic lobe (2 × 1.5 × 0.4 cm). The part of the pancreas involved in the hernia was grossly enlarged. Microscopically, a zone of pressure atrophy of hepatic tissue was characterized by crowdedness of hepatocytes with pyknotic nuclei and faint eosinophilic cytoplasm and indistinct narrow sinusoids. The pancreas revealed hypertrophy of the acinar cells with an increase in the secretory granules and basophilic cytoplasm. This is the first report of duodenum herniation into the right ventral hepatic peritoneal cavity resulting in groove formation on the ventral hepatic surface in a 2-week-old chicken. PMID:23759688

    We analyzed the pharmacokinetics of C3G on data from twelve subjects, after 2-week multiple dosing of black bean (Phaseolus vulgaris, Cheongjakong-3-ho) seed coat extract, using the mixed effect analysis method (NONMEM, Ver. 6.2), as well as the conventional non-compartmental method. We also examined the safety and tolerability. The PK analysis used plasma concentrations of the C3G on day 1 and 14. There was no observed accumulation of C3G after 2-week multiple dosing of black bean seed coat extract. The typical point estimates of PK were CL (clearance)=3,420 l/h, V (volume)=7,280 L, Ka (absorption constant)=9.94 h-1, ALAG (lag time)=0.217 h. The black bean seed coat extract was well tolerated and there were no serious adverse events. In this study, we confirmed that a significant amount of C3G was absorbed in human after given the black bean seed coat extract. PMID:22915990

    Background: Platelet-rich plasma (PRP) is defined as an autologous concentration of plasma with a greater count of platelets than that of whole blood. Its action depends on the released growth factors from platelets. It has been investigated and used in numerous fields of medicine. Recently, PRP has received growing attention as a potential therapeutic tool for hair loss. Aims: To evaluate the efficacy and safety of PRP injections in the scalp of patients with androgenetic alopecia. Settings and Design: Prospective cohort study. Materials and Methods: 20 patients, 18 males and 2 females, with androgenetic alopecia were enrolled in the study. PRP was prepared using a single spin method (Regenlab SA). Upon activation, it was injected in the androgen-related areas of scalp. Three treatment sessions were performed with an interval of 21 days and a booster session at 6 months following the onset of therapy. Statistical Analysis: Statistical analysis of the data was performed using the Statistical Package for the Social Sciences (SPSS), version 19.0 (IBM, NY, USA). Results: Hair loss reduced and at 3 months it reached normal levels. Hair density reached a peak at 3 months (170.70 ± 37.81, P < 0.001). At 6 months and at 1 year, it was significantly increased, 156.25 ± 37.75 (P < 0.001) and 153.70 ± 39.92 (P < 0.001) respectively, comparing to baseline. Patients were satisfied with a mean result rating of 7.1 on a scale of 1-10. No remarkable adverse effects were noted. Conclusions: Our data suggest that PRP injections may have a positive therapeutic effect on male and female pattern hair loss without remarkable major side effects. Further studies are needed to confirm its efficacy. PMID:25722600

    Background Current treatments for schizophrenia are often only partially effective. Aims Assess the possible benefit of using adjunctive Naikan therapy, a cognitive approach based on self-reflection that originated in Japan for the treatment of schizophrenia. Methods After resolution of acute psychotic symptoms, 235 psychiatric inpatients with schizophrenia who had a middle school education or higher were randomly assigned to a control group (n=112) that received routine medication and inpatient rehabilitative treatment or an intervention group (n=123) that also received adjunctive Naikan therapy for 2 hours daily, 5 days a week for 4 weeks. The patients were then discharged and followed up for 12 months. The Positive and Negative Syndrome Scale (PANSS), Personal and Social Performance scale (PSP), and Insight and Attitude Questionnaire (ITAQ) were used to assess patients at enrollment, after the 1-month intervention, and after the 12-month follow-up. Evaluators were blind to the group assignment of patients. Results Only 13 (10.6%) of the intervention group participants relapsed over the 12-month follow-up, but 23 (20.5%) control group participants relapsed (X2=4.50, p=0.034). Using a modified intention-to-treat analysis and a repeated measure analysis of variance, the PANSS, PSP, and ITAQ total scores all showed significantly greater improvement over the 12-month follow-up in the Naikan group than in the control group. The drop in mean chlorpromazine-equivalent dosage from enrollment to the end of follow-up was significantly different in the intervention group but not in the control group, though the change in dosage over time between groups was not statistically significant. Conclusions This study provides robust support for the effectiveness of Naikan therapy as an adjunctive treatment during the recovery period of schizophrenia. Compared to treatment as usually, adjunctive Naikan therapy can sustain the improvement in psychotic symptoms achieved during acute

    Accelerated (dose-dense) chemotherapy, in which the frequency of administration is increased without changing total dose or duration, may increase the efficacy of cancer chemotherapy. We performed a randomised Phase II study to assess the safety and relative toxicity of AC (doxorubicin; cyclophosphamide) vs E(epirubicin)C given by conventional or accelerated schedules as neoadjuvant or adjuvant chemotherapy for early breast cancer. Furthermore, the relative toxicity of doxorubicin and epirubicin remains uncertain. Patients were randomised to one of four arms; four courses of standard 3 weekly cyclophosphamide 600 mg m−2 in combination with doxorubicin 60 mg m−2 (AC) vs epirubicin 90 mg m−2 (EC) 3 weekly vs the same regimens administered every 2 weeks with pegfilgrastim (G-CSF). A total of 126 patients were treated, 42 with standard AC, 42 with accelerated AC, 19 with standard EC and 23 with accelerated EC. Significantly more grade 3/4 day one neutropenia was seen with standard (6/61, 10%) compared to accelerated (0/65,) regimens (P=0.01). A trend towards more neutropenic sepsis was seen in the combined standard and accelerated AC arms (12/84, 14%) compared to the combined EC arms (1/42, 2%), P=0.06. Falls in left ventricular ejection fraction were not increased with accelerated treatment. Accelerated AC and EC with pegfilgrastim are safe and feasible regimens in the treatment of early breast cancer with less neutropenia than conventional 3 weekly schedules. PMID:19165198

    Long-term effects of Kamp K'aana, a 2-week residential weight management camp, on body mass index (BMI) measures were evaluated on 71 of 108 (66%) obese youth 10 to 14 years of age. Measures were obtained at 11-month study follow-up (n = 38) or extracted from medical record (n = 33). Compared with baseline, BMI increased (P < 0.001), but both BMI percentile and BMI z score decreased (98.7 ± 1.0 to 97.3 ± 6.7 and 2.34 ± 0.30 to 2.23 ± 0.34, P < 0.001). A decrease in BMI z score of ≥0.2 units was seen in 27% of the participants (P < 0.001). The short program has sustained effect. PMID:26327212

    There was fewer paper about the relation between the Hamilton Depression Rating Scale (17 Items, HDRS-17) factors and stroke outcomes. Our aim was to investigate the influence of total score and factors of HDRS-17 on outcome of ischemic stroke at 1 year. A total of 1,953 patients with acute ischemic stroke were enrolled into a multicentered and prospective cohort study. The HDRS-17 was used to assess symptoms at 2 weeks after ischemic stroke. The Modified Ranking Scale (mRS) scores of 3-6 points and 0-2 points were regarded as poor outcome and benign outcome, respectively. At 1 year, 1,753 (89.8 %) patients had mRS score data. After adjusting for the confounders, patients with a total HDRS-17 score of ≥ 8 had a worse outcome at 1 year (OR = 1.62, 95 % CI 1.18-2.23). Symptoms of suicide (OR = 1.89, 95 % CI 1.27-2.83), decreased or loss of interest of work (OR = 1.89, 95 % CI 1.38-2.58), retardation (OR = 1.74, 95 % CI 1.27-2.38), psychic anxiety (OR = 1.72, 95 % CI 1.26-2.34), and agitation (OR = 1.61, 95 % CI 1.08-2.40) increased the risks for poor outcome by >60 %, respectively. Depressed mood, somatic anxiety, somatic symptoms-gastrointestinal, and early insomnia also increased the risk for poor outcome by nearly 50 %, respectively. A total HDRS-17 score of ≥ 8, and suicide, decreased or loss of interest of work, anxiety, agitation, retardation, depressed mood, somatic anxiety, somatic symptoms-gastrointestinal, and early insomnia of the HDRS-17 factors at 2 weeks after ischemic stroke increase the risk for poor outcome at 1 year.

    The aim of the study was to compare the effect of two acute puerperal metritis (APM) treatment protocols on uterine condition during the late puerperal period (5th to 7th week). Late gestation healthy cows (n = 21) were divided randomly in three equal groups. Parturitions were induced. Treatments of APM were started on the third day postpartum (PP). Group A was treated with an oxytocin analogue carbetocin for three days and intrauterine administration of cephapirin between days 15 and 17. Group B was given intramuscular injection of ceftiofur for five days followed by two injections of prostaglandin F2α, at an interval of 12 h, on the eighth day PP. Group C served as the control group with no treatment. Body temperature was recorded daily for 14 days PP. Uterine biopsies for bacteriology, and uterobrush samples for cytology, were taken once a week from the 5th to 7th week postpartum. No differences were found in body temperature on day 14 PP, presence of bacteriological infections and disappearance of uterine inflammatory signs diagnosed by cytological examination between experimental groups.

    The effect of the non-selective treatment of dairy cows with antibiotics (Chronicin foam--Galena, and Masticort PS--Poland) and the effect of teat disinfection (Jodonal A--Lachema) at the last milking in lactation was studied as exerted on the reduction in the occurrence of infection processes in mammary gland after calving. The trials were performed with 180 cows in three groups of 60 animals. At the last milking the mammary secretion of each cow was sampled for bacteriological examination. Two cow groups were treated at the same time. The occurrence of infection processes in the mammary gland in the period after calving can be characterized as follows: a) in the period after calving the control group had an increased proportion of cows with an infection process in their udders (from 58.3% at the end of lactation to 68.3% in the period of 14 days following calving); b) in the group treated with Chronicin foam the infection was reduced by 3/5, i. e. from 71.7% of cows infected at the start of drying off to 28.3% with infection process after calving; c) in the group treated with Masticort PS the infection after calving was reduced by 3/4 as compared with the infection at the onset of drying off, i. e. from 80% to 20%. In the control group 20% of the cows recovered spontaneously. The preparation Chronicin foam showed 79.1% therapeutic effectiveness. Therapy with Masticort PS was successful in 81.3% of the animals.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:6433531

    AIM:To investigate the changes of gastric acid production and its mechanism in shock period of severe burn in rats.METHODS:A rat model with 30% TBSA full thickness burn injury was employed and the gastric acid production,together with gastric mucosal blood flow (GMBF) and energy charge (EC) were measured serially within 48h postburn.RESULTS:The gastric acid production in the acute shock period was markedly inhibited after severe burn injury.At the 3rd h postburn,the gastric juice volume, total acidity and acid output were already significantly decreased (P < 0.01 =, and reached the lowest point, 0.63mL/L ± 0.20mL/L, 10.81mmol/L ± 2.58mmol/L and 2.23mmol/h ± 0.73mmol/h respectively, at the 12th h postburn. Although restored to some degree 24h after thermal injury, the variables above were still statistically lower, compared with those of control animals at the 48th h postburn. The GMBF and EC were also significantly reduced after severe burns, consistent with the trend of gastric acid production changes.CONCLUSION:Gastric acid production, as well as GMBF and EC was predominantly decreased in the early postburn stage, suggesting that gastric mucosal ischemia and hypoxia with resultant disturbance in energy metabolism, but not gastric acid proper, might be the decisive factor in the pathogenesis of AGML after thermal injury, and that the preventive use of anti-acid drugs during burn shock period was unreasonable in some respects. Therefore, taking effective measures to improve gastric mucosal blood perfusion as early as possible postburn might be more preferable for the AGML prevention and treatment. PMID:11819529

    The keratocystic odontogenic tumor (KCOT) is a relatively common oral and maxillofacial lesion with specific characteristics such us rapid growth, extension into the surrounding tissues and high rates of recurrence. Various treatment modalities have been reported. Due to the very thin and friable lining characteristic of the tumor, enucleation can be difficult undertaken and for this reason it is associated with the highest recurrence rates. A 22-year-old male referred to our clinic due to a slight expansion in the right mandible from 2 years ago. He has a history of occurrence of KCOT in this region that was treated surgically by enucleation and curettage 5 years ago. Cone beam computed tomography showed a multilocular radiolucent lesion that extended from the angle of the mandible to the symphysis. Incisional biopsy showed a KCOT recurrence that surgically treated with resection of the right mandible by continuity preservation. Selection of the best treatment modality and also a periodical lifelong follow-up is very important to reduce the rate of recurrence and morbidity of the patient. PMID:24049625

  5. Donepezil Treatment Restores the Ability of Estradiol to Enhance Cognitive Performance in Aged Rats: Evidence for the Cholinergic Basis of the Critical Period Hypothesis

    Recent studies suggest that the ability of estradiol to enhance cognitive performance diminishes with age and/or time following loss of ovarian function. We hypothesize that this is due, in part, to a decrease in basal forebrain cholinergic function. This study tested whether donepezil, a cholinesterase inhibitor, could restore estradiol effects on cognitive performance in aged rats that had been ovariectomized as young adults. Rats were ovariectomized at 3 months of age, and then trained on a delayed matching to position (DMP) T-maze task, followed by a configural association (CA) operant condition task, beginning at 12–17 or 22–27 months of age. Three weeks prior to testing, rats started to receive either donepezil or vehicle. After one week, half of each group also began receiving estradiol. Acclimation and testing began seven days later and treatment continued throughout testing. Estradiol alone significantly enhanced DMP acquisition in middle-aged rats, but not in aged rats. Donepezil alone had no effect on DMP acquisition in either age group; however, donepezil treatment restored the ability of estradiol to enhance DMP acquisition in aged rats. This effect was due largely to a reduction in the predisposition to adopt a persistent turn strategy during acquisition. These same treatments did not affect acquisition of the CA task in middle-aged rats, but did have small but significant effects on response time in aged rats. The data are consistent with the idea that estrogen effects on cognitive performance are task specific, and that deficits in basal forebrain cholinergic function are responsible for the loss of estradiol effect on DMP acquisition in aged ovariectomized rats. In addition, the data suggest that enhancing cholinergic function pharmacologically can restore the ability of estradiol to enhance acquisition of the DMP task in very old rats following long periods of hormone deprivation. Whether donepezil has similar restorative effects on other

    The prevalence of trimethoprim (TMP) and sulfamethoxazole (SMX) resistance in commensal E. coli from pigs was tested in this study. E. coli was derived from three groups of piglets in successive stages of metaphylactic therapy and from two groups of sows 10 and 18 weeks after the treatment. MIC values of TMP and SMX were determined for a total of 352 strains. The presence of resistance genes (dfrA1, dfrA5, dfrA7, dfrA12, dfrA17, sul1, sul2, sul3) and class 1 and 2 integron-associated dfrA gene cassettes was tested. Resistance to TMP was very high during the administration of the antimicrobial (from 97 to 100%) and amounted to 86% and 69% in the post-exposure period; MIC > 32 mg/L. The isolates from all groups of pigs were resistant to sulfamethoxazole, with MIC > 1028 mg/L. The dfrA1 and sul1 genes (as part of integrons) dominated in E. coli from piglets, but the dfrA12 and sul1 genes were prevalent in E. coli from sows. Coexistence of the different dfrA genes was detected in 71 isolates from all groups of swine. Transcription analysis revealed that most of these genes were not transcribed, particularly gene cassettes of class 1 integrons. The research revealed a high level of resistance associated with the metaphylactic treatment, persistence and circulation of resistance in bacterial populations. Diverse genetic background with multiple and not transcribed resistance genes was observed. PMID:25689993

    Dietary trans fatty acids are associated with increased risk of CHD. We hypothesized that the changes in plasma lipids associated with a high intake of trans fatty acids would cause adverse effects on procoagulant and fibrinolytic activities. A randomized crossover controlled feeding study was conducted in twenty-nine men. A trans-rich diet supplying 10 % energy as trans- 18:1 was compared with diets in which the trans fatty acids were replaced either with carbohydrate or oleate; each diet was taken for 2 weeks in random order. Fasting fibrinogen and d-dimer concentrations and factor VII coagulant, plasminogen activator inhibitor type 1 and tissue plasminogen activator did not differ between diets. Postprandially, tissue plasminogen activator activity increased and plasminogen activator inhibitor type 1 activity decreased on all diets. Factor VIIc increased postprandially by 15 and 17 % on the trans and oleate diets respectively, compared with an 11 % increase on the carbohydrate diet; the mean difference between oleate and carbohydrate diets was 6 (95 % CI 0.2, 11.9) %. The LDL-cholesterol:HDL-cholesterol and apolipoprotein B : apolipoprotein A-I ratios increased by 13 (95 % CI 5.7, 21.8) and 10 (95 % CI 3.1, 17.2) % respectively on the trans diet compared with the oleate diet and by 6 (95 % CI 0.1,12.7) and 7 (95 % CI 0, 13.5) % respectively compared with the carbohydrate diet. Plasma HDL2-cholesterol concentration was 18 (95 % CI 0.7, 35.9) % lower on the trans diet compared with the oleate diet. The results confirm adverse effects of trans fatty acids on HDL-cholesterol concentrations, but suggest that trans fatty acids do not have any specific effects on known haemostatic risk markers for cardiovascular disease in healthy young men in the short-term.

    Enzyme replacement therapy (ERT) with exogenous glucocerebrosidase is indicated to treat symptomatic Gaucher disease (GD), a rare, inherited metabolic disorder. ERT with velaglucerase alfa, which is produced in a human cell line using gene activation technology, was studied in a 12-month phase III trial in Japanese patients with type 1 or 3 GD who were switched from imiglucerase ERT (n=6); the current, open-label, 12-month extension study was designed to assess longer-term safety and efficacy. Two adult and three pediatric patients (aged <18years) were enrolled into the extension study. Every-other-week intravenous infusions were administered for 63-78weeks at average doses between 51.5 and 60.7units/kg. Three non-serious adverse events were considered related to velaglucerase alfa treatment, but no patient discontinued from the study. Six serious but non-drug-related adverse events were reported. No patient tested positive for anti-velaglucerase alfa antibodies. Hemoglobin concentrations, platelet counts, and liver and spleen volumes (normalized to body weight) in these patients were generally stable over a cumulative 24-month period from the baseline of the parent trial. The data suggest that velaglucerase alfa was well tolerated and maintained clinical stability in Japanese GD patients over 2years after switching from imiglucerase.

    Benefits of cochlear prostheses for the deaf are dependent on survival and excitability of the auditory nerve. Degeneration of deafferented auditory nerve fibers is prevented and excitability maintained by immediate replacement therapy with exogenous neurotrophic factors, in vivo. It is important to know whether such interventions are effective after a delay following deafness, typical for the human situation. This study evaluated the efficacy of brain-derived neurotrophic factor (BDNF) and ciliary neurotrophic factor axokine-1 analogue (CNTF Ax1) application, 2 or 6 weeks postdeafening, in preventing further degeneration and a decrease in excitability. Guinea pigs were deafened and implanted with intracochlear stimulating electrodes, a scala tympani cannula-osmotic pump system, and auditory brainstem response (ABR) recording electrodes. Subjects received BDNF + CNTF Ax1 or artificial perilymph (AP) treatment for 27 days, beginning at 2 or 6 weeks following deafening. Electrical (E) ABR thresholds increased following deafening. After 1 week, in the 2-weeks-delayed neurotrophic factor treatment group, EABR thresholds decreased relative to AP controls, which were statistically significant at 2 weeks. In the 6-week delay group, a tendency to enhanced EABR sensitivity began at 2 weeks of treatment and increased thereafter, with a significant difference between neurotrophic factor- and AP-treated groups across the treatment period. A clear, statistically significant, enhanced survival of spiral ganglion cells was seen in both neurotrophic factor treatment groups relative to AP controls. These findings demonstrate that BDNF + CNTF Ax1 can act to delay or possibly even reverse degenerative and, likely apoptotic, processes well after they have been activated. These survival factors can rescue cells from death and enhance electrical excitability, even during the period of degeneration and cell loss when the spiral ganglion cell population is reduced by >50% (6 weeks).

    Purpose: Topotecan (TPT), a camptothecin analog, is currently used to treat human ovarian and small-cell lung cancer and is in clinical trials for other tumor sites. However, it is unknown whether chronomodulation of TPT treatment is beneficial. We examined the effects of administering TPT or X-radiation (XR) alone at different times of the day or night. Methods: We treated mice bearing human colorectal tumor xenografts at four different times representing the early rest period (9 AM or 3 HALO [hours after light onset]), late rest period (3 PM or 9 HALO), early active period (9 PM or 15 HALO), and late active period (3 AM or 21 HALO) of the mice. We gave either TPT (12 mg/kg, injected i.p.) or XR (4 Gy, directed to the tumor) twice weekly on Days 0, 4, 7, 10 within 2 weeks. Results: Treatment with either TPT or XR at 3 AM demonstrated the greatest efficacy (measured by a tumor regrowth assay) without significantly increasing acute toxicity (assessed by a decrease in leukocyte counts or body weight). Conversely, treatment at 3 PM, in particular, showed increased toxicity without any enhanced efficacy. Conclusions: Our study provided the first evidence that chronomodulation of TPT treatments, consistent with the findings of other camptothecin analogs, is potentially clinically beneficial. Additionally, our findings suggest that chronomodulation of fractionated XR treatments is also potentially clinically beneficial.

    Background Physical activity is recommended to promote healthy aging. Defining the importance of activities such as walking in achieving higher levels of physical activity might provide indications for interventions. Objective To describe the importance of walking in achieving higher levels of physical activity in older adults. Methods The study included 42 healthy subjects aged between 51 and 84 years (mean body mass index 25.6 kg/m2 [SD 2.6]). Physical activity, walking, and nonwalking activity were monitored with an accelerometer for 2 weeks. Physical activity was quantified by accelerometer-derived activity counts. An algorithm based on template matching and signal power was developed to classify activity counts into nonwalking counts, short walk counts, and long walk counts. Additionally, in a subgroup of 31 subjects energy expenditure was measured using doubly labeled water to derive physical activity level (PAL). Results Subjects had a mean PAL of 1.84 (SD 0.19, range 1.43-2.36). About 20% of the activity time (21% [SD 8]) was spent walking, which accounted for about 40% of the total counts (43% [SD 11]). Short bouts composed 83% (SD 9) of walking time, providing 81% (SD 11) of walking counts. A stepwise regression model to predict PAL included nonwalking counts and short walk counts, explaining 58% of the variance of PAL (standard error of the estimate=0.12). Walking activities produced more counts per minute than nonwalking activities (P<.001). Long walks produced more counts per minute than short walks (P=.001). Nonwalking counts were independent of walking counts (r=−.05, P=.38). Conclusions Walking activities are a major contributor to physical activity in older adults. Walking activities occur at higher intensities than nonwalking activities, which might prevent individuals from engaging in more walking activity. Finally, subjects who engage in more walking activities do not tend to compensate by limiting nonwalking activities. Trial Registration

    Background: Chronic subdural hematoma (CSDH) is frequent pathology in neurosurgical practice. The aim of this study is to present the first series of patients with CSDH, who got surgically treated in Clinic of Neurosurgery, University Clinical Center of Kosovo. Materials and Methods: This is a retrospective study that included 137 patients with CSDH who had been treated during the period 2008–2012. The data were collected and analyzed from the archives and protocols of the University Clinical Center of Kosovo. Patients were analyzed in many aspects such as age, gender, etiological factors, clinical features, localization, diagnoses, methods of surgical interventions, recurrences and mortality of patients. Results: From 137 patients with CSDH, 106 (77.3%) were males and 31 (22.7%) females. Average age of patients was 62.85 years. Analyzed according to the decades, the highest number of causes with CSDH was between 70 and 79 years (46%). The head trauma has been responsible for CSDH in 88 patients (64.3%), while the main symptom was headache (92 patients or 67.1%). One burr-hole trepanation with closed drainage system has been used in majority of cases (in 101 patients or 73.7%). The recurrence of CSDH was 6.5%, whereas mortality 2.9%. Conclusion: CSDH is more common in elderly patients. The male-female ratio is 3.4:1. Like other authors we also think that treatment with one burr-hole and drainage is a method of choice, because of its simplicity and safety. PMID:25883478

    The objective of this multicenter, double-blind, placebo-controlled, randomized withdrawal study was to evaluate the efficacy and safety of ALO-02, an abuse-deterrent formulation containing pellets of extended-release oxycodone hydrochloride (HCl) surrounding sequestered naltrexone HCl, compared with placebo in the treatment of moderate-to-severe chronic low back pain. An open-label titration period in which all patients received ALO-02 was followed by a double-blind treatment period where patients meeting treatment response criteria were randomized to either a fixed dose of ALO-02 or placebo. Daily average low back pain was assessed using an 11-point numeric rating scale (NRS)-Pain. Of the 663 patients screened, 410 received ALO-02 during the open-label conversion and titration period and 281 patients were randomized to the double-blind treatment period (n = 134, placebo; n = 147, ALO-02). Change in the mean NRS-Pain score from randomization baseline to the final 2 weeks of the treatment period was significantly different favoring ALO-02 compared with placebo (P = 0.0114). Forty-four percent of patients treated with placebo and 57.5% of patients treated with ALO-02 reported ≥30% improvement in weekly average NRS-Pain scores from screening to the final 2 weeks of the treatment period (P = 0.0248). In the double-blind treatment period, 56.8% of patients in the ALO-02 group and 56.0% of patients in the placebo group experienced a treatment-emergent adverse event (TEAE). The most common treatment-related TEAEs for ALO-02 during the treatment period were nausea, vomiting, and constipation, consistent with opioid therapy. ALO-02 has been demonstrated to provide significant reduction of pain in patients with chronic low back pain and has a safety profile similar to other opioids. PMID:25993547

    Periodic polymers can be made by self assembly, directed self assembly and by photolithography. Such materials provide a versatile platform for 1, 2 and 3D periodic nano-micro scale composites with either dielectric or impedance contrast or both, and these can serve for example, as photonic and or phononic crystals for electromagnetic and elastic waves as well as mechanical frames/trusses. Compared to electromagnetic waves, elastic waves are both less complex (longitudinal modes in fluids) and more complex (longitudinal, transverse in-plane and transverse out-of-plane modes in solids). Engineering of the dispersion relation between wave frequency w and wave vector, k enables the opening of band gaps in the density of modes and detailed shaping of w(k). Band gaps can be opened by Bragg scattering, anti-crossing of bands and discrete shape resonances. Current interest is in our group focuses using design - modeling, fabrication and measurement of polymer-based periodic materials for applications as tunable optics and control of phonon flow. Several examples will be described including the design of structures for multispectral band gaps for elastic waves to alter the phonon density of states, the creation of block polymer and bicontinuous metal-carbon nanoframes for structures that are robust against ballistic projectiles and quasi-crystalline solid/fluid structures that can steer shock waves.

The patient had Angle’s Class I malocclusion with flaring of the maxillary and mandibular incisors. Pre adjusted edgewise appliance (MBT prescription) was fixed to the maxillary and mandibular teeth. Then corticotomy was performed on the cortical bone of the buccal sides in the maxillary anterior regions. Intrusion and retraction initiated immediately after the corticotomy. The intrusive arch was adjusted once in every 2 weeks. The total treatment time for intrusion was 5 months. Cephalometric superimpositions showed no anchorage loss, and panoramic radiographs showed neither significant reduction in the crestal bone height nor marked apical root resorption. A corticotomy-facilitated orthodontic treatment shortened treatment period without any anchorage loss or adverse effects. PMID:24551742

    [Purpose] The aim of this study was to investigate the effect of a back care pillow (BCP) on pain, lumbar range of motion (LROM) and functional disability of patients with chronic non-specific low back pain (LBP). [Subjects and Methods] Fifty-two subjects who were aged between 20–69 years old, who presented with LBP of more than 3 months duration with a numerical rating scale (NRS) value of at least 4 were randomly assigned to treatment (BCP) and control (CON) groups. Participants in each group received six sessions of the 30 minutes treatment for two weeks. The BCP group was asked to wear the BCP during the daytime during the study period. Pain, lumbar ROM and functional disability were assessed before and after the 2-week treatment, and at the end of a 12-week follow up. [Results] After the 2-week treatment and 12-week follow up, all outcomes had improved in both groups; the BCP group had maintained the decrease in pain intensity and improved lumbar ROM in the extension position after the 12-week follow up, and showed better improvements in all outcomes at 2 weeks and after the 12-week follow up. [Conclusion] BCP combined with physical therapy had better pain, lumbar ROM and functional disability outcomes than physical therapy alone. PMID:26311921

    Periodontal tissue changes exerted by external forces in orthodontic treatment allow tooth movement. The changes in periodontal tissues i.e. inflammation can be monitored using gingival crevicular fluid (GCF). GCF is a component of saliva. Saliva could be used to monitor periodontal disease progression. The use of saliva to monitor periodontal tissues changes during orthodontic treatment is still unknown. Therefore, we observed the profiles of inflammatory markers namely creatine kinase ('CK), nitric oxide (NO), lactate dehydrogenase (LDH) and aspartate aminotransferase (AST) in saliva of orthodontic patients to evaluate their importance in orthodontic treatment. A total of 21 subjects (13 female and 8 male) participated in this study. Samples were collected from gingival crevicular fluid at three period of archwire changes: baseline (M0), 2 weeks after 0.014" NiTi archwire (M1), and 2 weeks after 0.018" NiTi archwire (M2). All enzyme activities i.e. CK, LDH and AST were measured spectrophotometrically at 340 nm. Griess assay was used to measure nitric oxide level. CK activity, NO level, LDH activity and AST activity in saliva samples did not show significant differences among period of archwire changes. The use of inflammatory marker profiles in saliva may not represent the changes in periodontal tissues during orthodontic treatment.

    Mice were X-irradiated on day 14, 15 or 16 of gestation with 1.0 Gy. This did not result in an increased tumour frequency in the offspring until 12 months. Mice treated with ethylnitrosourea (ENU) (45 mg/kg) on these gestation days developed a significantly increased tumour frequency in the lungs and liver, and in the ovaries after treatment on day 15 of gestation. Additionally this experiment was the first to show that ENU treatment on gestation day 14, 15 or 16 results in haemangiosarcomas of the subcutis at a low incidence (2.0, 2.4, 2.6 per cent). After combined treatment with these two agents in the sequence X+ENU and an interval of 4 h, a significantly increased incidence rate of animals with tumours was observed in the offspring treated on gestation day 14 or 16. Moreover, the treatment on gestation day 16 exhibited the highest tumour frequency per examined animal (5.7) of all treatment groups. This result is due to a relatively uniform increase of all tumor types. Within this pattern, the frequency of liver tumours was most marked. The diagnosed liver tumours were significantly augmented after X+ENU treatment on day 16. In the reverse sequence (ENU+X), the total tumour outcome was not significantly altered compared with the effects of ENU alone. However, detailed analysis also showed a significant augmentation of the liver tumour frequency with treatment on day 15. PMID:3496295

    Childhood/adolescent antipsychotic drug (APD) use is exponentially increasing worldwide, despite limited knowledge of the long-term effects of early APD treatment. Whilst investigations have found that early treatment has resulted in some alterations to dopamine and serotonin neurotransmission systems (essential to APD efficacy), there have only been limited studies into potential long-term behavioural changes. This study, using an animal model for childhood/adolescent APD treatment, investigated the long-term effects of aripiprazole, olanzapine and risperidone on adult behaviours of male and female rats. Open-field/holeboard, elevated plus maze (EPM), social interaction and forced swim (FS) tests were then conducted in adult rats. Our results indicated that in the male cohort, early risperidone and olanzapine treatment elicited long-term hyper-locomotor effects (open-field/holeboard and FS tests), whilst a decrease in depressive-like behaviour (in FS test) was observed in response to olanzapine treatment. Furthermore, anxiolytic-like behaviours were found following testing in the open-field/holeboard and EPM in response to all three drug treatments. Effects in the female cohort, however, were to a far lesser extent, with behavioural attributes indicative of an increased depressive-like behaviour and hypo-locomotor activity exhibited in the FS test following early risperidone and olanzapine treatment. These results suggest that various APDs have different long-term effects on the behaviours of adult rats. PMID:26577063

    The treatment approach to patients 80 years of age and older with gastroesophageal cancer at Baylor Scott and White in Temple, Texas, has historically favored conservative measures in the form of palliation and observation. To evaluate this trend in practice, the administered treatments and subsequent patient outcomes of this group were retrospectively reviewed. The study group included all patients 80 years of age and older with a diagnosis of gastroesophageal cancer seen at our facility between 1991 and 2010. Of the 117 cases, 49% received none of the available treatment modalities. The median overall survival (OS) of patients who received treatment, however, was significantly longer than the OS of those who did not, regardless of modality. Specifically, surgical intervention offered an almost double median OS compared with no therapy (6.8 vs. 3.9 months, respectively; P = 0.02); chemotherapy, an almost 4-fold OS benefit (14.8 vs. 3.9 months; P = 0.03); and radiation therapy, a >3-fold OS benefit (11.1 vs. 3.5 months; P = 0.04). These results further substantiate chronological age as an inaccurate predictor of treatment benefit, and age alone should not dictate the administration or withholding of available treatment options.

    This study examines the performance of an anaerobic fixed-film bioreactor under seasonal operating conditions prevailing in medium and small size Tequila factories: start-up, normal operation and particularly, during the restart-up after a long stop and starvation period. The proposed start-up procedure attained a stable biofilm in a rather short period (28 days) despite unbalanced COD/N/P ratio and the use of non-acclimated inoculum. The bioreactor was restarted-up after being shut down for 6 months during which the inoculum starved. Even when biofilm detachment and bioreactor clogging were detected at the very beginning of restart-up, results show that the bioreactor performed better as higher COD removal and methane yield were attained. CE-SSCP and Q-PCR analyses, conducted on the biofilm prokaryotic communities for each operating condition, confirmed that the high COD removal results after the bioreactor clogging and the severe starvation period were mainly due to the stable archaeal and resilient bacterial populations.

    A case of thyrotoxic periodic paralysis is reported in a Hispanic man with an unusual recurrence six weeks after radioactive iodine treatment. Thyrotoxic periodic paralysis has now been well characterized in the literature: it occurs primarily in Orientals with an overwhelming male preponderance and a higher association of specific HLA antigens. Clinical manifestations include onset after high carbohydrate ingestion or heavy exertion, with progressive symmetric weakness leading to flaccid paralysis of the extremities and other muscle groups, lasting several hours. If hypokalemia is present, potassium administration may help abort the attack. Although propranolol can be efficacious in preventing further episodes, the only definitive treatment is establishing a euthyroid state. The pathophysiology is still controversial, but reflects altered potassium and calcium dynamics as well as certain morphologic characteristics within the muscle unit itself.

    OBJECTIVE: To examine the efficacy of a slow-release formulation of diltiazem as adjunctive therapy in patients with treatment-resistant bipolar disorder. DESIGN: Retrospective study. PATIENTS: Eight female patients with treatment-resistant bipolar disorder. INTERVENTIONS: Patients were administered diltiazem and monitored for a 6-month period before starting diltiazem and a 6-month period after starting the drug. OUTCOME MEASURES: All patients were seen at least monthly and usually every 2 weeks. The frequency and severity of both depressive and manic episodes were examined during the 6-month period after starting diltiazem, and compared with those during the 6-month period before diltiazem treatment. RESULTS: There was a statistically significant decrease in the frequency and severity of both manic and depressive episodes in these patients after they started treatment with diltiazem, compared with the period before they started treatment with diltiazem (p < 0.001). There was no evidence of side effects requiring patient withdrawal or of drug interactions. CONCLUSIONS: The results support previous suggestions that calcium-channel antagonists may be an effective adjunctive treatment in the management of bipolar disorder. Further controlled clinical studies are needed to confirm this small, open-label, retrospective study. PMID:10863888

    Cell-mediated immunity is essential for protection against the intracellular bacterium Francisella tularensis, which causes tularemia. Positive in vitro T-cell responses in the form of lymphocyte proliferation and lymphokine interleukin 2 (IL-2) and gamma interferon (IFN-gamma) secretion are found in memory immunity. Studies on the secretion of lymphokines with regard to the developing immunity to F. tularensis have not been published. Therefore, 14 subjects with no clinical history of tularemia were vaccinated with a live F. tularensis vaccine strain. The in vitro responses of five subjects (antigen-induced mononuclear cell and whole blood culture DNA synthesis and cytokine secretion) were measured twice a week throughout the period from 0 to 35 days after vaccination, and the peripheral blood lymphocyte subpopulations of nine subjects were determined between days 0 and 14. Positive reactions, i.e., responses exceeding those on day 0, were reached on day 10 with regard to the whole blood culture DNA synthesis response and IL-2 and IFN-gamma secretion and on day 14 with regard to the mononuclear cell DNA synthesis response and tumor necrosis factor alpha (TNF-alpha) secretion. No measurable IL-4 was found in either the immune or nonimmune supernatants. Since the secretion of TNF-alpha was related to immunization, this points to the specificity of the phenomenon, even though the type of secreting cell is not yet known. If it is shown later that specific T cells produce it, the TNF-alpha response and the negative IL-4 finding may speak for the importance of the Th1-like pattern in immunity to F. tularensis.

    Treatment of adolescents with growth hormone deficiency (GHD) during the transition period is a controversial issue. This paper is a contribution from the Italian community of paediatric and adult endocrinologists surveyed in a Delphi panel. The Delphi method is a structured communication technique, originally developed as a systematic, interactive forecasting method that relies on a panel of experts. The experts answer questionnaires in two or more rounds. There was substantial agreement on the definition of the problems associated with the diagnosis and treatment of adolescents with GHD in the transition period, as well as on the identification of the controversial issues which need further studies. There is general consensus on the need of re-testing all isolated idiopathic GHD after at least 30-day withdrawn from treatment, while in patients with multiple pituitary deficiency and low IGF-I levels there is generally no need to re-test. In patients with permanent or confirmed GHD, a starting low rhGH dose (0.01-0.03 mg per day) to be adjusted according to IGF-I concentrations is also widely accepted. For those continuing treatment, the optimal therapeutic schedule to obtain full somatic maturation, normalization of body composition and bone density, cardiovascular function and Quality of Life, need to be evaluated.

    This study assessed clinical scenarios of continuing monoclonal antibody (mAb) treatment for (+)-methamphetamine (METH) addiction, and the implications of missing or discontinuing this therapy. We hypothesized that chronic anti-METH mAb7F9 (METH KD = 9 nM) treatment of rats could significantly decrease METH-induced behaviors; even with repeated METH challenges, use of METH doses in excess of mAb binding sites, and after discontinuing mAb treatment which results in a 10-fold reduction in mAb7F9 serum concentrations. Male Sprague Dawley rats (n=6/group) were treated with i.v. saline or a loading dose of mAb7F9 to achieve instant steady-state conditions followed by two weekly (141 mg/kg) doses ending on day 14. METH (0.56 mg/kg) was administered four hours and three days after each saline or mAb7F9 treatment, and on day 21. This produced locomotion and rearing behavior that lasted about 120 min in control rats. In mAb7F9 treated rats, METH-induced distance traveled was significantly reduced from 60–120 min (P<0.05) on days 0–21 and rearing was significantly reduced from 60–120 min on days 0–17. METH serum concentrations determined 5 hrs after METH dosing was significantly increased in mAb7F9-treated rats after all METH challenges. On days 24 and 28 (the final day), the rats were administered a 3-fold higher METH dose (1.68 mg/kg). MAb7F9 treated rats showed a substantially earlier termination of the METH-induced locomotion on both days, even though the METH dose exceeded mAb7F9’s binding capacity. METH brain concentrations determined 5 hrs after METH on day 28 were also significantly decreased in mAb7F9-treated rats. In conclusion, over one month, mAb7F9 significantly and continuously bound METH and reduced METH-induced locomotor effects even after discontinuation of mAb treatment and challenge with higher METH doses.

    In this study, we investigated the impact of Problem Drink on depression. Forty participants with depression were divided into 2 groups: non-Problem Drinker (NPD) group (n = 22) and Problem Drinker (PD) group (n = 18) according to Alcohol Use Disorder Identification Test (AUDIT) score (NPD < 12, PD > or = 12). Depression was assessed by the Mini-International Neuropsychiatric Interview. The effect of medication on depressive symptoms was monitored over 12 weeks using the Hamilton Rating Scale for Depression (HAM-D). Significant improvement in HAM-D score was observed at 2 weeks in NPD patients but not until 4 weeks in PD patients. Total HAM-D scores were lower in NPD than in PD patients at the end of the treatment period. Therapeutic doses (dose of antidepressant used was equivalent to greater than 75 mg of imipramine) of antidepressants resulted in significant improvement in HAM-D scores at 2 weeks in NPD patients, but not until 8 weeks in PD patients and brought lower HAM-D scores in NPD than in PD patients at the end of the treatment period. The AUDIT score and total alcohol consumption during the study period were negatively correlated to the improvement in HAM-D score. In NPD patients, the level of education of patients in remission was higher than those by patients not in remission. In contrast, level of education of patients in remission were similar to those in PD patients not in remission. The above results suggest that co-occurrence of alcohol use disorders with depression is associated with a lower response to antidepressants which may reflect not only the result of biological alterations in the brain by chronic ethanol ingestion but also an inhibitory effect of ethanol on antidepressant action in the brain. Drinking-related cognitive dysfunction may also relate to the decreased response to treatment in the depressed patients with comorbid Problem Drinker. PMID:24427900

    The present aimed to develop a hormonal therapy based on the insertion of a progesterone (P4) insert (PI) during 10 d plus an estradiol injection (E2) at PI removal before the onset of breeding of beef heifers. In Exp. 1, the plasma P4 profile of prepubertal heifers showed that the insertion of a PI or 24 d previously used P4 insert (UPI) sustained plasma P4 above 1 ng/mL for at least the first 7 d of the treatment. In Exp. 2 there was no positive effect of additional estradiol benzoate (EB) administered at the insertion of UPI on the proportion of heifers with a corpus luteum (CL/Treated) 30 d after UPI removal [UPI + EB = 85.3%(a) (n = 134); EB + UPI + EB = 80.8%(a) (n = 125)]; however, both were greater (P < 0.0001) than the Control group [60.3%(b) (n = 129)]. In Exp. 3, a positive effect (P=0.01) of UPI treatment and both E2 supplementations [EB and estradiol cypionate (EC); P = 0.10] at the UPI removal was observed on CL/Treated [Control = 42.5%(b) (n = 94); UPI = 58.5%(a) (n= 130); UPI + EB = 64.0%(a) (n = 128); UPI + EC = 67.2%(a) (n = 128)]. However, greater pregnancy per treated heifer (P/Treated) following artificial insemination (AI) upon estrus detection was achieved when EC was applied [Control = 20.2%(b); UPI = 29.2%(ab); UPI + EB = 26.6%(b); UPI + EC = 36.7%(a)]. In Exp. 4, the treatment prior to the timed AI (TAI) tended to improve pregnancy per TAI [P/AI; Control 43.6% (n = 298) vs. UPI+EC 51.9% (n = 342); P = 0.08], but increased P/Treated [26.5% vs. 43.3%; P < 0.001]. Thus, UPI + EC treatment were efficient in increasing the CL/Treated, tended to improve the P/AI and consequently enhanced P/Treated of zebu beef heifers. PMID:26169688

    Previous research in this laboratory has shown that chronic treatment of adult male rats with an anabolic-androgenic steroid (AAS) produced anxiolytic behavior and increased the functional response of cortical gamma-aminobutyric acid(A) (GABA(A)) receptors. The experiments reported here were aimed at further characterizing the effect of chronic AAS exposure on cerebral cortical GABA(A) receptors. Adult male rats were injected with dianabol (1,4-androstadien-17alpha-methyl-17beta-ol-3-one; 10 mg/kg/day, SC) for 4 weeks. A significant decrease in ventral prostate gland weight was found after 2 weeks of dianabol, and returned to control levels 3 and 10 days after steroid discontinuation. Testicular weights decreased throughout the treatment period but reached statistical significance only during the withdrawal period. Serum 3alpha-androstanediol level was marginally increased afer 2 weeks of dianabol injection, and was significantly decreased at 3 and 10 days after withdrawal. GABA-stimulated 36chloride (Cl-) influx in cortical synaptoneurosomes was increased in animals treated with dianabol for 2 and 4 weeks, and remained elevated 3 days after dianabol withdrawal, returning to control levels at withdrawal day 10. The increase in receptor efficacy was associated with a transient increase in receptor sensitivity (inverse of EC50), apparent after 2 weeks of AAS treatment and at withdrawal day 3. In a follow-up experiment, metabolites of dianabol were tested for the in vitro efficacy in potentiating GABA-stimulated Cl- transport. Only 3alpha-androstanedial and androsterone were found to have potent stimulatory effects. The 3beta-reduced metabolites were inactive, as were metabolites that contained a methyl group at the 17alpha position. These results point to significant facilitative effects of dianabol treatment on brain GABA(A) receptors via the metabolic formation of neuroactive steroids. PMID:8632710

    The use of fixed combinations in acne vulgaris (acne) is very common, however comparative clinical trial data are limited. Cutaneous tolerability can influence patient compliance, and concerns about skin irritation with topical acne treatments have lead to a number of comparative split-face studies.
    Recently, a new fixed combination product was introduced (clin 1.0%-BP 3.75% gel) that was shown to be effective in reducing both inflammatory and noninflammatory lesions in moderate to severe acne. Here, we assess the tolerability of clin 1.0%-BP 3.75% gel compared with adap 0.1%-BP 2.5% gel in healthy volunteers with no apparent facial redness or dryness over 21-days, using a split-face methodology.
    Especially over the first two weeks of treatment, clin 1.0%-BP 3.75% gel was more tolerable than adap 0.1%-BP 2.5% gel, with statistically significant differences in cumulative change from baseline starting as early as day 8 (dryness) and day 9 (erythema), and composite index on days 8-12 and 16. Transepidermal water loss was less with clin 1.0%-BP 3.75% gel, although the difference was not statistically significant.

    Objective—To determine whether implantable cardioverter-defibrillator (ICD) treatment is beneficial in elderly patients with life threatening ventricular tachyarrhythmias.
Design—Since January 1984, ICDs were implanted in 450 patients to evaluate surgical risk, complications and mean survival in relation to patient age; 81 patients (18%) were ⩽ 50 years at the time of ICD implant, 254 patients (56%) were between 51 and 64 years, and the remaining 115 (26%) were ⩾ 65 years. Epicardial lead systems were implanted in 209 patients (46%), while transvenous lead systems were implanted in 241 (54%).
Results—13 patients (3%) died perioperatively, more often after epicardial (11 of 209 patients, 5%) than after transvenous ICD implantation (one of 241 patients, < 1%) (p < 0.05). During a mean (SD) follow up of 28 (24) months (range < 1 to 114 months), 90 patients (20%) died. Of these, nine (2%) died from sudden arrhythmic death; five (1%) died suddenly, probably as a result of non-arrhythmic causes; 55 (12%) died from other cardiac causes (congestive heart failure, myocardial infarction); and 21 (5%) died from non-cardiac causes. The three, five, and seven year survival for arrhythmic mortality was 95% in patients ⩽ 50 years compared with a three year survival of 93% and a five and seven year survival of 91% in patients of 51 to 64 years, and a three, five, and seven year survival of 99% in patients ⩾ 65 years. 362 patients (80%) received ICD discharges (21 (43) shocks per patient), with a similar incidence among all three patient groups (⩽ 50 years, 80%; 51 to 64 years, 81%; ⩾ 65 years, 79%). The time interval between ICD implant and the first ICD treatment was shorter in patients ⩾ 65 years (8 (8) months) than in patients between 51 and 64 years (11 (14) months) or ⩽ 50 years (11 (11) months) (p < 0.05). Survival time following first appropriate shock was 30 (24) months in patients ⩽ 50 years, 30 (26

    Approximately 750 leiomyomas of 250 symptomatic patients were treated by LITT over a five-year period. Only 12% were lost to follow-up. Most were treated by a combination of the KTP/YAG laser, rarely by one or the other alone, and a few with the diode laser. The fiber optic was inserted 2 cm apart and, depending on the size of the tumor, 480 - 20,000 Joules were required. Most were treated laparoscopically but very large myomas were treated percutaneously under ultrasound control. Symptoms were nearly always relieved and the six failures were found to be due to unrecognized adenomyosis and other associated pathology. Half the patients complaining of infertility became pregnant and, in those whose only pathology had been leiomyomas it approached 90%. Vaginal delivery was not found to be contraindicated. Finally, oestrogen receptors and epidermal growth factor were found to be destroyed. It is concluded that LITT enables leiomyomas of all sizes and locations to be treated by a minimally invasive method with preservation of the uterus.

  19. The classical electrostatic periodic table, capacitance of few electron dielectric spheres and a novel treatment of one- and two-electron finite quantum wells

    NASA Astrophysics Data System (ADS)

    Lafave, Tim, Jr.

    The centerpiece of this dissertation is the discovery of the classical electrostatic periodic table of elements through non-linear ground state energies coincident with atomic shell-filling resulting from symmetry properties of discrete electrons constrained by a spherically-symmetric system. The time-independent electrostatic equilibrium configuration of few electrons confined to a large classical dielectric sphere is obtained by minimization of the total interaction energy. The interactions model yields more than twice the energy predicted by the classical Gauss model. Each N-electron system is proposed as a unique phase characterized by its symmetry properties. A new mono-phasic capacitance definition of dielectric spheres is derived from the fundamental relation Q=CV. Large differences from the Gauss model are obtained for few-electron systems, but convergence is found in the metallic limit. Of particular significance is the means by which symmetry-dependent properties of atomic-scale devices may be exploited by controlling the internal architecture of charge distributions. This work will be useful to modeling of many-electron chemical and biological systems, such as macromolecules, owing largely to symmetry differences between the Gauss model and the interactions model. The foundation upon which all Nature rests is the symmetry of fundamental particles.

    To reduce HIV incidence, prevention programs centered on the use of antiretrovirals require scaling-up HIV testing and counseling (HTC). Home-based HTC services (HBHTC) increase HTC coverage, but HBHTC has only been evaluated during one-off campaigns. Two years after an initial HBHTC campaign (“round 1”), we conducted another HBHTC campaign (“round 2”) in Likoma (Malawi). HBHTC participation increased during round 2 among women (from 74% to 83%, p<0.01). New HBHTC clients were recruited, especially at ages 25 and older. Only 6.9% of women but 15.9% of men remained unreached by HBHTC after round 2. HIV prevalence during round 2 was low among clients who were HIV-negative during round 1 (0.7%), but high among women who first tested during round 2 (42.8%). The costs per newly diagnosed infection increased significantly during round 2. Periodically conducting HBHTC campaigns can further increase HTC, but supplementary interventions to enroll individuals not reached by HBHTC are needed. PMID:23180155

    The effect of increased gravity force on the circadian period of body temperature and activity of rats was investigated using rats implanted with a small radio telemetry device and, after a 2-week recovery and a 3-week control period at 1G, rotated at for 4 weeks at a constant 2G field in a 18-ft-diam centrifuge. Measurements of the mean freerunning period of the temperature and activity rhythms after 10 days showed that the exposure to 2G led to a functional separation of the pacemakers that regulate the activity and the temperature in the animals. Each pacemaker reacted differently: the activity period increased and the temperature period decreased. By the third or the fourth week, the activity and the temperature periods have returned to 1G control levels.

    Background. Vaginal infections are common, frequently recur, and may increase women's risk for sexually transmitted infections (STIs). We tested the efficacy of a novel regimen to prevent recurrent vaginal infections. Methods. Human immunodeficiency virus (HIV)–negative women 18–45 years old with 1 or more vaginal infections, including bacterial vaginosis (BV), vulvovaginal candidiasis (VVC), or Trichomonas vaginalis (TV), were randomly assigned to receive vaginal suppositories containing metronidazole 750 mg plus miconazole 200 mg or matching placebo for 5 consecutive nights each month for 12 months. Primary endpoints, evaluated every 2 months, were BV (Gram stain) and VVC (positive wet mount and culture). Results. Participants (N = 234) were randomly assigned to the intervention (N = 118) or placebo (N = 116) arm. Two hundred seventeen (93%) women completed an end-of-study evaluation. The intervention reduced the proportion of visits with BV compared to placebo (21.2% vs 32.5%; relative risk [RR] 0.65, 95% confidence interval [CI] .48–.87). In contrast, the proportion of visits with VVC was similar in the intervention (10.4%) versus placebo (11.3%) arms (RR 0.92, 95% CI .62–1.37). Conclusions. Monthly treatment with intravaginal metronidazole plus miconazole reduced the proportion of visits with BV during 12 months of follow-up. Further study will be important to determine whether this intervention can reduce women's risk of STIs. PMID:25526757

    Aim: To test the short term efficacy and safety of an infrared warm compression device (IWCD, Eye Hot, Cept Co, Tokyo, Japan) as treatment for non-inflamed meibomian gland dysfunction (MGD). Methods: 37 subjects with non-inflamed obstructive MGD, with and without aqueous tear deficiency (ATD) dry eye, participated in a prospective non-comparative interventional case series. Symptom scores, face scores, tear evaporation rates, fluorescein and rose bengal vital staining, tear break up time (BUT), Schirmer test, meibomian gland obstruction, and meibography were compared before and after 2 weeks of therapy. Results: In a total of 37 cases, total subjective symptom scores and subjective face scores improved significantly, from 12.3 (SD 5.9) to 8.4 (6.1), and from 7.0 (1.7) to 5.3 (2.0) (both p <0.0001). The results for tear evaporation rates during forced blinking (p = 0.002), fluorescein staining (p = 0.03), rose bengal staining (p = 0.03), BUT (p <0.0001), and meibomian gland orifice obstruction score (p <0.0001) had also improved significantly at the end of the 2 week period of infrared thermotherapy. No complaints and/or complications of the IWCD were reported. Conclusion: The IWCD was effective and safe for the treatment of MGD. Improved tear stability associated with release of meibum is a possible mechanism of this treatment. PMID:12446375

    A number of immunomodulatory effects have been attributed to the medicinal plants Echinacea angustifolia and Goldenseal (Hydrastis canadensis); however, little is known about whether treatment with these plants can enhance antigen-specific immunity. We investigated the antigen-specific in vivo immunomodulatory potential of continuous treatment with Echinacea and Goldenseal root extract over a period of 6 weeks using rats that were injected with the novel antigen keyhole limpet hemocyanin (KLH) and re-exposed to KLH after the initial exposure. Immunoglobulin production was monitored via ELISA continuously over a period of 6 weeks. The Echinacea-treated group showed a significant augmentation of their primary and secondary IgG response to the antigen, whereas the Goldenseal-treated group showed an increase in the primary IgM response during the first 2 weeks of treatment. Our results suggest that medicinal plants like Echinacea or Goldenseal may enhance immune function by increasing antigen-specific immunoglobulin production. PMID:10424448

    Purpose Our study aimed to examine the relationship between intelligence and health-related quality of life (HRQOL) in children (6-13 years old) diagnosed as having a brain tumor. Materials and Methods We administered a Korean version of the Wechsler Intelligence Scale for Children-III, the Pediatric Quality of Life Inventory, version 4.0 (PedsQL), the Korean version of the Parenting Stress Index-Short Form, and the Korean Version of the Parenting Sense of Competence (K-PSOC) scale before or after initial radiotherapy (T1) and after treatment termination (T2). In total, 13 patients completed both the T1 and T2 interviews. Results Scores significantly declined between T1 and T2 on the full-scale intelligence quotients (FIQ), verbal intelligence quotients (VIQ), performance intelligence quotients (PIQ), similarity and coding tests, as well as the K-PSOC, which measures parental anxiety. FIQ scores at T1 were correlated with the self-reported PedsQL total scores (r=0.739) and the parent proxy-report PedsQL scores for school functioning (r=0.706) at T2. Also, the FIQ scores at T2 were correlated with the self-reported PedsQL total scores (r=0.748) and scores for physical health (r=0.728) at T2. Conclusion The cognitive ability and intelligence level of the patients significantly declined between on and off treatment periods, and higher intelligence functioning at both on and off treatment was correlated with long-term higher HRQOL. Further investigations that monitor intelligence, HRQOL and parenting stress over a longer period, using a greater number of participants, are needed. PMID:23364961

    During recent decades, biological medications play a crucial role for treating rheumatologic disorders and thus are strongly recommended for initial treatment of ankylosing spondylitis. However, because of high cost of biological drugs, the use of these drugs has been limited. In current series, we tried to assess safety of low-dose etanercept as a common usable biological drug in patients with ankylosing spondylitis. In a case-series study, 4 men with ankylosing spondylitis were treated with low-dose etanercept (25 mg/2 weeks) plus methotrexate (10 mg/week). Safety was assessed by measuring rate of differences in severity of clinical manifestations and level of C-reactive protein (CRP). After the completion of treatment with low-dose etanercept, inflammatory low back pain and morning stiffness was reduced lower than 30 min in all patients. Only one patient had baseline high serum ESR and positive CRP that was changed to negative following treatment protocol. At one-year follow-up, all participants continued their regular treatment regimen with the etanercept survival rate 100%. Neither side effects related to drug nor clinical complications were observed within the follow-up period. Our findings suggest that low-dose etanercept (25 mg/2 weeks) has an acceptable safety and effectiveness profile in individuals with ankylosing spondylitis and can be good alternative instead of conventional therapy with etanercept (25 mg two times per week).

    Periodical cicadas (Magicicada spp.) in the USA are famous for their unique prime-numbered life cycles of 13 and 17 years and their nearly perfectly synchronized mass emergences. Because almost all known species of cicada are non-periodical, periodicity is assumed to be a derived state. A leading hypothesis for the evolution of periodicity in Magicicada implicates the decline in average temperature during glacial periods. During the evolution of periodicity, the determinant of maturation in ancestral cicadas is hypothesized to have switched from size dependence to time (period) dependence. The selection for the prime-numbered cycles should have taken place only after the fixation of periodicity. Here, we build an individual-based model of cicadas under conditions of climatic cooling to explore the fixation of periodicity. In our model, under cold environments, extremely long juvenile stages lead to extremely low adult densities, limiting mating opportunities and favouring the evolution of synchronized emergence. Our results indicate that these changes, which were triggered by glacial cooling, could have led to the fixation of periodicity in the non-periodical ancestors. PMID:26365061

    The objective of this study was to evaluate the potential benefit of utilizing a pharmacogenomic testing report to guide the selection and dosing of psychotropic medications in an outpatient psychiatric practice. The non-randomized, open label, prospective cohort study was conducted from September 2009 to July 2010. In the first cohort, depressed patients were treated without the benefit of pharmacogenomic testing (the unguided group). A DNA sample was obtained from patients in the unguided group, but the results were not shared with either the physicians or patients until the end of the 8-week study period. In the second cohort (the guided group), testing results were provided at the beginning of the 8-week treatment period. Depression ratings were collected at baseline and after 2 weeks, 4 weeks and 8 weeks of treatment using the Quick Inventory of Depressive Symptomatology, Clinician Rated (QIDS-C16) and the 17-item Hamilton Rating Scale for Depression (HAM-D17). Clinician and patient satisfaction was also assessed. The reduction in depressive symptoms achieved within the guided treatment group was greater than the reduction of depressive symptoms in the unguided treatment group using either the QIDS-C16 (P=0.002) or HAM-D17 (P=0.04). We concluded that a rapidly available pharmacogenomic interpretive report provided clinical guidance that was associated with improved clinical outcomes for depressed patients treated in an outpatient psychiatric clinic setting.

    The major branch of the Seine river from the confluence with the Marne river to the entrance of the estuary is deeply affected by the release of wastewater from the huge Paris agglomeration. In the first years of 2000, the largest part of the effluents were still discharged at the Seine-Aval (Achères) treatment plant with only a standard, low residence time, activated sludge treatment, thus releasing a high ammonium load. NH4 concentration as high as 7 mgN/l were frequently observed downstream from Paris agglomeration. Cébron et al. (2003, 2005) and Garnier et al. 2007 described in details how this massive reduced nitrogen concentrations triggered the growth of nitrifying bacteria, already present in the upstream Seine and Marne rivers, but also brought in large amount by the effluents of the wastewater treatment plant themselves. The decrease of ammonium concentration was slow, however, and was only completed 200 km downstream, in the upper estuarine area, where it causes a severe oxygen deficiency. Since 2007, important changes occurred in the treatment of nitrogen in the Parisian wastewater purification plants. In 2007, the Seine-Aval plant treated up to 90% of the ammonium contained in wastewater through nitrification, and 30% of the total supply of nitrates is treated by denitrification. These modifications have of course favorably affected the water quality of the Seine river: ammonium concentrations are reduced by a factor of 5 and the area of oxygen depletion in the upstream estuary is no more observed. However, nitrites, still released in the effluents, are a matter of concern for the water quality of the Seine downstream from Paris. Using measurements of potential microbial activities carried out with the same experimental protocol for the 2000-2003 and 2012-2013 periods, we here examine and model the dynamics of ammonium oxidizing and nitrite oxidizing microbial populations before and after the implementation of nitrification treatment of Paris

    A systematic literature review and meta-analyses (where appropriate) were performed to update the previous AASM practice parameters on the treatments, both dopaminergic and other, of RLS and PLMD. A considerable amount of literature has been published since these previous reviews were performed, necessitating an update of the corresponding practice parameters. Therapies with a STANDARD level of recommendation include pramipexole and ropinirole. Therapies with a GUIDELINE level of recommendation include levodopa with dopa decarboxylase inhibitor, opioids, gabapentin enacarbil, and cabergoline (which has additional caveats for use). Therapies with an OPTION level of recommendation include carbamazepine, gabapentin, pregabalin, clonidine, and for patients with low ferritin levels, iron supplementation. The committee recommends a STANDARD AGAINST the use of pergolide because of the risks of heart valve damage. Therapies for RLS secondary to ESRD, neuropathy, and superficial venous insufficiency are discussed. Lastly, therapies for PLMD are reviewed. However, it should be mentioned that because PLMD therapy typically mimics RLS therapy, the primary focus of this review is therapy for idiopathic RLS.

    This study aimed at evaluating the use of polypropylene fabrics in weaned pig facilities (5-10 weeks of age) during the winter period to improve thermal environment and energy saving for heating. Two experiments were conducted to validate the effects of fabrics (F) compared to control (C) in three 2-week periods using natural ventilation (assay 1, 2013) and forced ventilation (assay 2, 2014). Air temperature was greater in F than in C compartments in both years, particularly during the first 2-week periods (2 °C of mean difference). Natural ventilation was not enough to maintain relative humidity levels below 70 % at the end of the postweaning period (9-10 weeks of age) in both groups (F and C), whereas forced ventilation allowed controlling daily mean relative humidity levels <60 %. About 12-26 % of the radiant heat was transmitted through the fabrics cover, depending on the wavelength. There were no differences on growth performance of piglets in the two compartments in both years. The use of polypropylene fabrics was associated with a significant electric energy saving for heating during the first (data available only in 2014) and second 2-week period in both years. In conclusion, polypropylene fabrics may be an interesting tool to provide optimal environmental conditions for weaned piglets in winter, especially during the two first weeks after weaning. Their transmittance properties allow trapping infrared emission produced by the piglets and heating, avoiding heat losses through the roof, and therefore saving heating energy. PMID:25910465

Natural ventilation was not enough to maintain relative humidity levels below 70 % at the end of the postweaning period (9-10 weeks of age) in both groups (F and C), whereas forced ventilation allowed controlling daily mean relative humidity levels <60 %. About 12-26 % of the radiant heat was transmitted through the fabrics cover, depending on the wavelength. There were no differences on growth performance of piglets in the two compartments in both years. The use of polypropylene fabrics was associated with a significant electric energy saving for heating during the first (data available only in 2014) and second 2-week period in both years. In conclusion, polypropylene fabrics may be an interesting tool to provide optimal environmental conditions for weaned piglets in winter, especially during the two first weeks after weaning. Their transmittance properties allow trapping infrared emission produced by the piglets and heating, avoiding heat losses through the roof, and therefore saving heating energy.

  13. Oral contraceptives in the immediate postpartum period.

    Although there is a critical need for effective contraception in the immediate postpartum period for women who are not breastfeeding, this need must be balanced against the inherent risks. The most effective form of contraceptive protection--oral contraceptives (OCs)--can present an increased risk of thromboembolism in the period after delivery. The thrombotic changes associated with pregnancy, and the statistics and vascular damage following a delivery, can combine to create greater potential for thromboembolism after delivery than during pregnancy. Reported here is the case of a 21-year-old woman who, 4 weeks postpartum, developed pain and swelling in the right lower calf and mottled discoloration extending from the proximal thigh to the toes. A diagnosis of deep venous thrombosis was made and heparin was administered. In the hospital, the patient experienced pleuritic chest pain and diaphoresis. A ventilation-perfusion scan indicated a pulmonary embolism. 1 week after delivery, the patient had initiated use of Triphasil. Although this woman had other risk factors (obesity, light cigarette smoking, and a sedentary life-style), OC use in the immediate postpartum period may have been the final factor precipitating the thromboembolic event. It is recommended that OC use should be delayed until at least 2 weeks postpartum in women without other risk factors for thromboembolism and until 4-6 weeks postpartum in those with such factors.

    concentration decreased up to 14th day post-partum and then started increasing from 21st day onward. Conclusion: Hematobiochemical parameters are indicative of health status of animals. Significantly low values of Hb, PCV, and TLC during first 2 weeks post-partum are indicative of stress. Catabolism of protein occurred during 2 weeks post-partum, as observed from increase in urea concentration. Decrease TGs and high level of NEFA during the transition period are suggestive of utilization of lipids for the supply of energy. High glucose level on 0 day indicates that the animals were in positive energy status. PMID:27051179

    Scabies is commonly treated with acaricides but the treatment of choice is still controversial. This study aimed at comparing the efficacy of oral ivermectin vs. lindane lotion 1% for the treatment of scabies. Four hundred fourty patients with scabies were enrolled, and randomized into two groups: the first group received a single dose of oral ivermectin 200 microg/kg body weight, and the second group were treated with two applications of topical lindane lotion 1%, with a 1-week interval. Treatment was evaluated at intervals of 2 and 4 weeks, and if there was treatment failure at the 2-week follow-up, treatment was repeated. Single dose of oral ivermectin provided a cure rate of 63.6% at the 2-week follow-up, which increased to 81.8% at the 4-week follow-up after repeating the treatment. Treatment with two applications of lindane lotion 1%, with a 1-week interval between them, was effective in 45.4% of patients at the 2-week follow-up, which increased to 63.6% at the 4-week follow-up after this treatment was repeated. Single dose ivermectin was as effective as two applications of lindane lotion 1% at the 2-week follow-up. After repeating the treatment, ivermectin was superior to lindane lotion 1% at the 4-week follow up. PMID:23829057

    Scabies is one of the three most common skin disorders in children, along with tinea and pyoderma. The treatment of choice is still controversial. The aim of this study is to compare the efficacy of permethrin 5% cream vs. crotamiton 10% cream in the treatment of scabies. In total, 350 patients with scabies were enrolled, and randomized into two groups. The first group received permethrin 5% cream on two occasions with a one-week interval, while the second group received topical crotamiton 10% cream and were told to apply this twice daily for five consecutive days. The treatment was evaluated at intervals of 2 and 4 weeks, and the treatment was repeated if treatment failure was found at the 2-week follow-up. Two applications of permethrin 5 % cream provided a cure rate of 70% at the 2-week follow-up, which increased to 85% at the 4-week follow-up after repeating the treatment. Treatment with single applications of crotamiton 10% cream was effective in 45% of patients at the 2-week follow-up, which increased to 65% at the 4-week follow-up after this treatment was repeated. Two applications of permethrin 5% cream was as effective as single applications of crotamiton 10% cream at the 2-week follow-up. After repeating the treatment, permethrin 5 % cream was superior to crotamiton 10% cream at the 4-week follow up. PMID:24881286

    Gastrointestinal nematodes (GIN) infection can impair milk production (MP) in dairy cows. To investigate whether MP would be optimized by spring targeted-selective anthelmintic treatment in grazing cows, we assessed (1) the effect on MP of an anthelmintic treatment applied 1.5 to 2 months after turn-out, and (2) herd and individual indicators associated with the post-treatment MP response. A randomized controlled clinical trial was conducted in 13 dairy farms (578 cows) in western France in spring 2012. In each herd, lactating cows of the treatment group received fenbendazole orally, control cows remained untreated. Daily cow MP was recorded from 2 weeks before until 15 weeks after treatment. Individual serum pepsinogen and anti-Ostertagia antibody levels (expressed as ODR), faecal egg count and bulk tank milk (BTM) Ostertagia ODR were measured at treatment time. Anthelmintic treatment applied during the previous housing period was recorded for each cow. In each herd, information regarding heifers’ grazing and anthelmintic treatment history was collected to assess the Time of Effective Contact (TEC, in months) with GIN infective larvae before the first calving. The effect of treatment on weekly MP averages and its relationships with herd and individual indicators were studied using linear mixed models with two nested random effects (cow within herd). Unexpectedly, spring treatment had a significant detrimental effect on MP (-0.92 kg/cow/day on average). This negative MP response was particularly marked in high producing cows, in cows not treated during the previous housing period or with high pepsinogen levels, and in cows from herds with a high TEC or a high BTM ODR. This post-treatment decrease in MP may be associated with immuno-inflammatory mechanisms. Until further studies can assess whether this unexpected result can be generalized, non-persistent treatment of immunized adult dairy cows against GIN should not be recommended in early grazing season.

  9. Wavelet periodicity detection algorithms

    Benedetto, John J.; Pfander, Goetz E.

    1998-10-01

    This paper deals with the analysis of time series with respect to certain known periodicities. In particular, we shall present a fast method aimed at detecting periodic behavior inherent in noise data. The method is composed of three steps: (1) Non-noisy data are analyzed through spectral and wavelet methods to extract specific periodic patterns of interest. (2) Using these patterns, we construct an optimal piecewise constant wavelet designed to detect the underlying periodicities. (3) We introduce a fast discretized version of the continuous wavelet transform, as well as waveletgram averaging techniques, to detect occurrence and period of these periodicities. The algorithm is formulated to provide real time implementation. Our procedure is generally applicable to detect locally periodic components in signals s which can be modeled as s(t) equals A(t)F(h(t)) + N(t) for t in I, where F is a periodic signal, A is a non-negative slowly varying function, and h is strictly increasing with h' slowly varying, N denotes background activity. For example, the method can be applied in the context of epileptic seizure detection. In this case, we try to detect seizure periodics in EEG and ECoG data. In the case of ECoG data, N is essentially 1/f noise. In the case of EEG data and for t in I,N includes noise due to cranial geometry and densities. In both cases N also includes standard low frequency rhythms. Periodicity detection has other applications including ocean wave prediction, cockpit motion sickness prediction, and minefield detection.

    Objective To evaluate the effect of a modified hand compression bandage in patients with a post-burn hand edema. Methods Patients were recruited from burn centers. We classified the patients into two groups: the modified hand compression bandage group comprising of 22 patients who had a modified hand compression bandage and received conventional physical therapy and the conventionally treated group, comprising of 20 patients who received only conventional physical therapy during the 4-week period post-burn. Hand circumference, hand skin thickness, and hand function were evaluated by grip strength, active range of motion (ROM), Jebsen hand function test, and visual analogue scale (VAS). These assessments were used to evaluate treatment effectiveness prior to the first treatment, 2 weeks after the first treatment, 4 weeks after the first treatment, and 4 months after the first treatment. Results As a result of repeated-measures analysis of variance on hand circumference, skin thickness, VAS, and each metacarpophalangeal joint ROM, we found significant differences that corresponded to time effect (p<0.05) and time×group (reciprocal action) effect (p<0.05). The results of grasp power, Jebsen hand function test, and each proximal interphalangeal joint ROM, show significant differences in accordance with the time effect (p<0.05), however, there was no reciprocal action effect (p>0.05). Conclusion The modified hand compression bandage will be clinically useful for the treatment of patients with post-burn hand edemas. PMID:27152286

    Background: Tumour necrosis factor (TNF) blocking agents decrease C reactive protein (CRP) levels in rheumatoid arthritis (RA). It has been shown that CRP may contribute to complement activation in RA. Objective: To assess the effect of intravenous infliximab treatment on complement activation, especially that mediated by CRP, in RA. Methods: 35 patients with active RA (28 joint count Disease Activity Score (DAS28) >4.4) were treated with intravenous injections of infliximab (3 mg/kg, at weeks 0, 2, 6, 14, and 22). Clinical response and plasma levels of complement activation products, of CRP and of CRP-complement complexes, which are specific markers for CRP mediated complement activation, were assessed at the indicated time points up to 22 weeks. The relationship between CRP and CRP-complement complexes was analysed by paired t test between two time points and by generalised estimated equation, to test differences of variables over time. Results: At 2 weeks after the first dose, infliximab significantly reduced overall C3 and C4 activation and plasma levels of CRP and CRP-complement complexes were also significantly reduced at this time point. The effects of infliximab on CRP and complement continued throughout the observation period and were more pronounced in patients with a good response to infliximab treatment. Conclusion: Treatment with infliximab decreases plasma levels of CRP and CRP dependent complement activation products and concomitantly may reduce complement activation in RA. Complement activation may be among the effector mechanisms of TNF in RA. PMID:15958758

    Chronic kidney disease associated mineral and bone disorders arise as a result of aberrant bone mineral metabolism in patients with advancing levels of renal dysfunction and end-stage renal disease. One of the cornerstones of treatment is the use of phosphate-binding agents. We describe the rationale and study design for a clinical trial to assess the safety and efficacy of ferric citrate as a phosphate binder. This trial is a three-period, international, multicenter, randomized, controlled clinical trial to assess the safety and efficacy of ferric citrate as a phosphate binder, consisting of a 2-week washout period, a 52-week safety assessment period in which subjects are randomized to ferric citrate or active control, and a 4-week efficacy assessment period in which subjects randomized to ferric citrate in the safety assessment period are randomized to ferric citrate or placebo. Eligible subjects include end-stage renal disease patients who have been treated with thrice-weekly hemodialysis or peritoneal dialysis for at least 3 months in dialysis clinics in the United States and Israel. Primary outcome measure will be the effect of ferric citrate vs. placebo on the change in serum phosphorus. Safety assessments will be performed by monitoring adverse events, concomitant medication use, and sequential blood chemistries (including iron parameters, phosphorus, and calcium). This three-period trial will assess the efficacy of ferric citrate as a phosphate binder. If proven safe and efficacious, ferric citrate will likely provide an additional phosphate binder to treat chronic kidney disease associated mineral and bone disorders. PMID:22702490

    Cyanocuprol is markedly effective in tuberculosis, and we believe that it will play an important part in clinical medicine. It may be used more generally than tuberculin. The amount of the dose is closely related to the reaction and the final results. It should be determined for each patient after a careful examination of his symptoms. The maximum dose of 8.5 cc. should in no case be exceeded. The shortest interval between injections should be 2 weeks. If the drug is given after a shorter interval, no improvement is observed and the effects are sometimes dangerous. In order to obtain the best results the patient should be placed under conditions of complete physical and mental rest after the injection; this applies even to light cases. Care should also be taken to secure rest for the lesion. During the period of the treatment irritants to the lesion, such as potassium iodide or tuberculin, should be avoided; apricot juice, guaiacol and its derivatives, and iodol are contraindicated. No marked idiosyncrasy has been noted and no accumulative effects have been observed. PMID:19868034

    A total of 45 patients with generalized anxiety disorder were treated twice daily for 2 weeks, on a double-blind basis, with 0.5 mg etizolam, 0.5 mg alprazolam or 3 mg bromazepam, and symptoms were assessed using Hamilton's rating scale for anxiety and Hamilton's rating scale for depression. Patients then received the same drug for a further 2 weeks, the drugs being given three times daily if a poor response was observed during the first 2 weeks. All drugs displayed equivalent anxiolytic activity after 2 weeks, but etizolam displayed a progressive increase in anxiolytic activity over 4 weeks of treatment. Etizolam also possessed a more marked antidepressant effect than did alprazolam or bromazepam. There were no differences in the tolerability of the three drugs. PMID:2572494

    Objective: There are different medications for the treatment of scabies but the treatment of choice is still controversial. This study aimed at comparing the efficacy of topical ivermectin versus malation 0.5% lotion for the treatment of scabies. Methods: In total, 340 patients with scabies were enrolled, and randomized into two groups: the first group received 1% ivermectin applied topically to the affected skin and the second group received topical malation 0.5% lotion and were told to apply this twice with 1 week interval. Treatment was evaluated at intervals of 2 and 4 weeks, and if there was treatment failure at the 2-week follow-up, treatment was repeated. Results: Two application of topical ivermectin provided a cure rate of 67.6% at the 2-week follow-up, which increased to 85.2% at the 4-week follow-up after repeating the treatment. Treatment with two applications of malation 0.5% lotion was effective in 44.1% of patients at the 2-week follow-up, which increased to 67.6% at the 4-week follow-up after this treatment was repeated. Conclusion:Two application of ivermectin was as effective as single applications of malation 0.5% lotion at the 2-week follow-up. After repeating the treatment, ivermectin was superior to malation 0.5% lotion at the 4-week follow up. PMID:23472617

    To establish a rapid bioassay system with neoplastic end-points for detection of colorectal carcinogenesis modifiers, we evaluated the effects of dextran sodium sulfate (DSS) treatment on the different stages of carcinogenesis in rats initiated with 1,2-dimethylhydrazine (DMH). F344 male rats were given three subcutaneous injections of DMH (40 mg/kg body weight) in a week, and were administered drinking water containing 1.0% DSS ad libitum either during or after the initiation period for a week, or both during and after initiation periods for 2 weeks. At the 10th week of the experiment, although the numbers of aberrant crypt foci were significantly decreased in all groups treated with DSS and given DMH-initiation as compared with DMH alone, dysplastic foci/adenomas/adenocarcinomas were increased. The incidences and multiplicities of these lesions were highest in rats treated with DSS after DMH-initiation period. At the 26th week, the incidences of adenocarcinomas (100 vs. 20% in DMH alone) and their multiplicities (6.6 +/- 0.8/rat vs. 0.2 +/- 0.4/rat in DMH alone) were also highest in this group. These results indicate that short-term DSS-treatment in the post-initiation period significantly accelerates DMH-induced colorectal tumor development in rats, so that this protocol may effective for establishment of a rapid bioassay system with neoplastic end-points.

    This article aims at highlighting the importance of suspecting thyrotoxicosis in cases of recurrent periodic flaccid paralysis; especially in Asian men to facilitate early diagnosis of the former condition. A case report of a 28 year old male patient with recurrent periodic flaccid paralysis has been presented. Hypokalemia secondary to thyrotoxicosis was diagnosed as the cause of the paralysis. The patient was given oral potassium intervention over 24 hours. The patient showed complete recovery after the medical intervention and was discharged after 24 hours with no residual paralysis. Thyrotoxic periodic paralysis (TPP) is a complication of thyrotoxicosis, more common amongst males in Asia. It presents as acute flaccid paralysis in a case of hyperthyroidism with associated hypokalemia. The features of thyrotoxicosis may be subtle or absent. Thus, in cases of recurrent or acute flaccid muscle paralysis, it is important to consider thyrotoxicosis as one of the possible causes, and take measures accordingly. PMID:21966655

  7. [Periodic abstinence: its possibilities].

    PubMed

    1981-05-01

    Experience with family planning mehods requiring periodic sexual abstinence has been varied. During the last decade interest has centered on 2 methods, the cervical mucus and the sympto-thermal, which are based on identifying the onset of the fertile period. During the 1970s, the Australian physicians John and Evelyn Billings developed the cervical mucus method, in which changes in the quanitity and characteristics of cervical mucus are used to determine the moment of ovulation. The sympto-thermal method depends on identification of the slight rise in basal body temperature that occurs in the latter part of the menstrual cycle as well as cervical mucus changes and sometimes the calendar to determine the fertile period. The Catholic Church has been the main proponent of periodic abstinence methods, but since 1973 the World Health Organization has invested US$3.3 million on research in such methods. The Billings method requires differentiating between dry, wet, and very wet mucus in the vagina and between different consistencies of mucus. The method ususally requires 1-3 months for instruction and sexual abstinence is usually recommended for the 1st month. The average number of days of required abstinence was 9 in a study of 66 women and 15-18 in a study of 870 women. Many women with short menstrual cycles do not experience postmenstrual dry days, in which case abstinence may be required as many as 13 days out of 23. 18.8% of users of periodic abstinence methods in 1 North American study became pregnant in the 1st year, but most were using the calendar method. Women who desired to terminate childbearing had only about 1/2 as many failures with periodic abstinence methods as did women wishing to postpone a birth. PMID:12311397

    The safety and efficacy of nortriptyline and fluoxetine were compared in a double-blind, randomized, multicenter 5-week trial involving 205 outpatients with acute major depression of moderate severity. Seventy-two nortriptyline and 84 fluoxetine patients completed at least 2 weeks of medication and were included in the efficacy analysis; all patients were evaluated for side effects. Average total scores on the Hamilton Rating Scale for Depression (HAM-D) for both treatment groups declined from 22-23 at baseline to 11.5 at the conclusion of the 5-week period. At Week, 5, 71% of nortriptyline patients and 65% of fluoxetine patients were much or very much improved. Fluoxetine was associated more frequently with nausea (p less than .05), while nortriptyline was associated more frequently with dry mouth (p less than .05). These results are discussed in the context of selecting between nortriptyline and fluoxetine for a particular depressed patient. PMID:2050651

    Periodically kicked turbulence is theoretically analyzed within a mean-field theory. For large enough kicking strength A and kicking frequency f the Reynolds number grows exponentially and then runs into some saturation. The saturation level Re(sat) can be calculated analytically; different regimes can be observed. For large enough Re we find Re(sat) approximately Af, but intermittency can modify this scaling law. We suggest an experimental realization of periodically kicked turbulence to study the different regimes we theoretically predict and thus to better understand the effect of forcing on fully developed turbulence.

  17. Astrophysical implications of periodicity

    Muller, Richard A.

    1988-01-01

    Two remarkable discoveries of the last decade have profound implications for astrophysics and for geophysics. These are the discovery by Alvarez et al., that certain mass extinctions are caused by the impact on the earth of a large asteroid or comet, and the discovery by Raup and Sepkoski that such extinctions are periodic, with a cycle time of 26 to 30 million years. The validity of both of these discoveries is assumed and the implications are examined. Most of the phenomena described depend not on periodicity, but just on the weaker assumption that the impacts on the earth take place primarily in showers. Proposed explanations for the periodicity include galactic oscillations, the Planet X model, and the possibility of Nemesis, a solar companion star. These hypotheses are critically examined. Results of the search for the solar companion are reported. The Deccan flood basalts of India have been proposed as the impact site for the Cretaceous impact, but this hypotheisis is in contradiction with the conclusion of Courtillot et al., that the magma flow began during a period of normal magnetic field. A possible resolution of this contradiction is proposed.

    Three experiments examined behavior in extinction following periodic reinforcement. During the first phase of Experiment 1, four groups of pigeons were exposed to fixed interval (FI 16s or FI 48s) or variable interval (VI 16s or VI 48s) reinforcement schedules. Next, during the second phase, each session started with reinforcement trials and ended with an extinction segment. Experiment 2 was similar except that the extinction segment was considerably longer. Experiment 3 replaced the FI schedules with a peak procedure, with FI trials interspersed with non-food peak interval (PI) trials that were four times longer. One group of pigeons was exposed to FI 20s PI 80s trials, and another to FI 40s PI 160s trials. Results showed that, during the extinction segment, most pigeons trained with FI schedules, but not with VI schedules, displayed pause-peck oscillations with a period close to, but slightly greater than the FI parameter. These oscillations did not start immediately after the onset of extinction. Comparing the oscillations from Experiments 1 and 2 suggested that the alternation of reconditioning and re-extinction increases the reliability and earlier onset of the oscillations. In Experiment 3 the pigeons exhibited well-defined pause-peck cycles since the onset of extinction. These cycles had periods close to twice the value of the FI and lasted for long intervals of time. We discuss some hypotheses concerning the processes underlying behavioral oscillations following periodic reinforcement. PMID:18992793

    Scabies is a common parasitic infestation that is an important public-health problem in many resource-poor regions. It is commonly treated with the insecticides but the treatment of choice is still controversial. This study aimed at comparing the efficacy of permethrin 2.5% cream vs. Tenutex emulsion for the treatment of scabies. In total, 440 patients with scabies were enrolled, and randomized into two groups The first group received permethrin 2.5% cream twice with one week interval and the second group received Tenutex emulsion and were told to apply this once whole-body application. Treatment was evaluated at intervals of 2 and 4 weeks, and if there was treatment failure at the 2-week follow-up, treatment was repeated.Two application of permethrin 2.5% cream provided a cure rate of 63.6% at the 2-week follow-up, which increased to 86.3% at the 4-week follow-up after repeating the treatment. Treatment with single applications of Tenutex emulsion was effective in 45.4% of patients at the 2-week follow-up, which increased to 59.1% at the 4-week follow-up after this treatment was repeated.Two application of permethrin 2.5% cream was as effective as single applications of Tenutex emulsion at the 2-week follow-up. After repeating the treatment, permethrin 2.5% cream was superior to Tenutex emulsion at the 4-week follow up. PMID:23829056

    The focus of this study was to assess the treatment performance and granule progression over time within a continuous flow reactor. A continuous flow airlift reactor was seeded with aerobic granules from a laboratory scale sequencing batch reactor (SBR) and fed with dairy wastewater. Stereomicroscopic investigations showed that the granules maintained their integrity during the experimental period. Laser diffraction investigation showed proof of new granules formation with 100-500 μm diameter after only 2 weeks of operation. The treatment performances were satisfactory and more or less similar to the ones obtained from the SBR. Thus, removal efficiencies of 81-93% and 85-94% were observed for chemical oxygen demand and biological oxygen demand, respectively. The N-NH(+)(4) was nitrified with removal efficiencies of 83-99% while the nitrate produced was simultaneously denitrified - highest nitrate concentration determined in the effluent was 4.2 mg/L. The removal efficiency of total nitrogen was between 52 and 80% depending on influent nitrogen load (39.3-76.2 mg/L). Phosphate removal efficiencies ranged between 65 and above 99% depending on the influent phosphate concentration, which varied between 11.2 and 28.3 mg/L. PMID:25714645

    Purpose: To evaluate the intra-fractional prostate movement range during the beam delivery and implement new IGRT method to correct the prostate movement during the hypofractionated prostate treatment delivery. Methods: To evaluate the prostate internal motion range during the beam delivery, 11 conventional treatments were utilized. Two-arc RapidArc plans were used for the treatment delivery. Orthogonal KV imaging is performed in the middle of the treatment to correct intra-fractional prostate movement. However, it takes gantry-mounted on-board imaging system relative long time to finish the orthogonal KV imaging because of gantry rotation. To avoid gantry movement and accelerate the IGRT processing time, orthogonal KV-MV image pair is tested using the OBI daily QA Cube phantom. Results: The average prostate movement between two orthogonal KV image pairs was 0.38cm (0.20cm ∼ 0.85cm). And the interval time between them was 6.71 min (4.64min ∼ 9.22 min). 2-arc beam delivery time is within 3 minutes for conventional RapidArc treatment delivery. Hypofractionated treatment or SBRT need 4 partial arc and possible non-coplanar technology, which need much longer beam delivery time. Therefore prostate movement might be larger. New orthogonal KV-MV image pair is a new method to correct the prostate movement in the middle of the beam delivery if real time tracking method is not available. Orthogonal KV-MV image pair doesn’t need gantry rotation. Images were acquired quickly which minimized possible new prostate movement. Therefore orthogonal KV-MV image pair is feasible for IGRT. Conclusion: Hypofractionated prostate treatment with less PTV margin always needs longer beam delivery time. Therefore prostate movement correction during the treatment delivery is critical. Orthogonal KV-MV imaging pair is efficient and accurate to correct the prostate movement during treatment beam delivery. Due to limited fraction number and high dose per fraction, the MV imaging dose is

  6. Cells anticipate periodic events

    2009-03-01

    We show that an amoeboid organism can anticipate the timing of periodic events. The plasmodium of the true slime mold Physarum polycephalum moves rapidly under favourable conditions, but stops moving when transferred to less-favourable conditions. Plasmodia exposed to unfavourable conditions, presented in three consecutive pulses at constant intervals, reduced their locomotive speed in response to each episode. When subsequently subjected to favourable conditions, the plasmodia spontaneously reduced their locomotive speed at the time point when the next unfavourable episode would have occurred. This implied anticipation of impending environmental change. After this behaviour had been evoked several times, the locomotion of the plasmodia returned to normal; however, the anticipatory response could subsequently be induced by a single unfavourable pulse, implying recall of the memorized periodicity. We explored the mechanisms underlying these behaviours from a dynamical systems perspective. Our results hint at the cellular origins of primitive intelligence and imply that simple dynamics might be sufficient to explain its emergence.

  7. Periodic minimal surfaces

    A minimal surface is one for which, like a soap film with the same pressure on each side, the mean curvature is zero and, thus, is one where the two principal curvatures are equal and opposite at every point. For every closed circuit in the surface, the area is a minimum. Schwarz1 and Neovius2 showed that elements of such surfaces could be put together to give surfaces periodic in three dimensions. These periodic minimal surfaces are geometrical invariants, as are the regular polyhedra, but the former are curved. Minimal surfaces are appropriate for the description of various structures where internal surfaces are prominent and seek to adopt a minimum area or a zero mean curvature subject to their topology; thus they merit more complete numerical characterization. There seem to be at least 18 such surfaces3, with various symmetries and topologies, related to the crystallographic space groups. Recently, glyceryl mono-oleate (GMO) was shown by Longley and McIntosh4 to take the shape of the F-surface. The structure postulated is shown here to be in good agreement with an analysis of the fundamental geometry of periodic minimal surfaces.

    ABSTRACT Cohen syndrome is a very rare disease. Complication by spinal deformity has been reported, but management and surgery for spinal deformity in Cohen syndrome has not been previously described. The objective of this study was to examine the outcome of surgical treatment for kyphoscoliosis of Cohen syndrome with a literature review. The patient was a 14-year-old male with the characteristics of Cohen syndrome: truncal obesity, mental retardation, arachnodactyly, microcephalia, and a facial malformation. Scoliosis was conservatively treated with a brace at 13 years of age, but the spinal deformity rapidly progressed within a year. Plain radiographs before surgery showed scoliosis of 47° (T5-T11) and 79° (T11-L3), and kyphosis of 86° (T7-L1). One-stage anteroposterior corrective fusion of T4-L3 was scheduled after 2-week Halo traction. Postoperative respiratory management was carefully performed because of Cohen syndrome-associated facial malformation, obesity, and reduced muscle tonus. Respiration was managed with intubation until the following day and no respiratory problems occurred. After surgery, thoracolumbar scoliosis was 28° (correction rate: 65%). Kyphosis was markedly improved from 86° to 20°, achieving a favorable balance of the trunk. The outcome is favorable at 6.5 years after surgery. In conclusion, Cohen syndrome is often complicated by spinal deformity, particularly kyphosis, that is likely to progress even in adulthood. In our patient, spinal deformity progressed within a short period, even with brace treatment. Surgery should be required before progression to the severe spinal deformity with careful attention to general anesthesia. PMID:24640185

    Efficacy and safety of fluticasone furoate nasal spray, administered using a unique side-actuated device, were evaluated in patients > or =12 years of age with seasonal allergic rhinitis to determine the optimal dose. A randomized, double-blind, parallel-group, placebo-controlled, dose-ranging study was performed on 641 patients who received placebo (n=128) or fluticasone furoate, 55 microg (n=127), 110 microg (n=127), 220 microg (n=129), or 440 microg (n=130), once daily for 2 weeks. Fluticasone furoate was significantly more effective than placebo for mean changes from baseline over the 2-week treatment period in daily reflective total nasal symptom score (primary end point; p < 0.001 each dose vs. placebo), morning predose instantaneous total nasal symptom score (p < 0.001 each dose versus placebo), daily reflective total ocular symptom score (p < or = 0.013 each dose versus placebo), and morning predose instantaneous total ocular symptom score (p < or = 0.019 for three highest doses versus placebo). The onset of action for fluticasone furoate nasal spray versus placebo was observed 8 hours after the first. dose of study medication in the 110 and 440 microg treatment groups (p < or = 0.032). The incidence of adverse events, results of clinical laboratory tests, and changes in 24-hour urinary cortisol values were similar between active treatment groups and placebo. The preliminary profile of fluticasone furoate is that of a rapidly effective therapy that confers 24-hour efficacy for both nasal and ocular symptoms with once-daily dosing. The 110-microg dose was chosen for phase III development because it achieved statistically significant and clinically meaningful results for all efficacy end points and provided the optimal risk-benefit ratio.

    Reorienting of voluntary attention enables the processing of stimuli at previously unattended locations. Although studies have identified a ventral fronto-parietal network underlying attention [1, 2], little is known about whether and how early visual areas are involved in involuntary [3, 4] and even less in voluntary [5] reorienting, and their temporal dynamics are unknown. We used transcranial magnetic stimulation (TMS) over the occipital cortex to interfere with attentional reorienting and study its role and temporal dynamics in this process. Human observers performed an orientation discrimination task, with either valid or invalid attention cueing, across a range of stimulus contrasts. Valid cueing induced a behavioral response gain increase, higher asymptotic performance for attended than unattended locations. During subsequent TMS sessions, observers performed the same task, with high stimulus contrast. Based on phosphene mapping, TMS double pulses were applied at one of various delays to a consistent brain location in retinotopic areas (V1/V2), corresponding to the evoked signal of the target or distractor, in a valid or invalid trial. Thus, the stimulation was identical for the four experimental conditions (valid/invalid cue condition × target/distractor-stimulated). TMS modulation of the target and distractor were both periodic (5 Hz, theta) and out of phase with respect to each other in invalid trials only, when attention had to be disengaged from the distractor and reoriented to the target location. Reorientation of voluntary attention periodically involves V1/V2 at the theta frequency. These results suggest that TMS probes theta phase-reset by attentional reorienting and help link periodic sampling in time and attention reorienting in space. PMID:27265395

    Geyser eruption frequency is not constant over time and has been shown to vary with small (???10-6) strains induced by seismic events, atmospheric loading, and Earth tides. The geyser system is approximated as a permeable conduit of intensely fractured rock surrounded by a less permeable rock matrix. Numerical simulation of this conceptual model yields a set of parameters that controls geyser existence and periodicity. Much of the responsiveness to remote seismicity and other small strains in the Earth can be explained in terms of variations in permeability and lateral recharge rates.

    In the past few years, researchers have uncovered evidence that several kinds of geological and biological events seem to show regular cycles of similar lengths. For example, Rohde and Muller [2005] looked at the record of diversity of marine organisms over the past 540 million years and found evidence for two cycles in the data—a roughly 62-million-year cycle and a longer cycle of about 140 million years. This was followed by reports of an approximately 56-million-year cycle in long-term stratigraphic sequences in sedimentary basins [Meyers and Peters, 2011] and a 59-million-year period in the marine strontium-isotope record [Melott et al., 2012]. A similar period may even exist in atmospheric carbon dioxide over the past 542 million years of the Phanerozoic [Franks et al., 2012].

    Breast feeding provides a lot of short and long-term benefits for the mother and the baby. It prevents the baby of gastrointestinal, urinary and respiratory infections, atopical conditions and assures long-term protection of cardiovascular and metabolic diseases. The breast feeding decreases the risk for the mother of ovary and breast carcinoma and creates a positive emotional bond between the mother and the baby Mother's milk is a species specific; its content is relatively stable regardless of mother's age race, way and place of living. Mother's milk is not sterile. There is a 10 year international trial held in Spanish and Finnish universities. It has identified and count all microorganisms in mother's milk (more than 700) and proved that their content and quantity varies according the age of the baby. Mother's milk is a source of lactobacillus for baby's intestines and most of them have probiotic potential. Lactobacillus fermentum Lc40 (hereditum) is isolated from mother's milk. It has a good viability in gastrointestinal system, high level of adhesion to intestinal epithelium cells, produces glutation--strong antioxidant, good antibacterial activity to entero-pathogens and potential of increasing the immunologic response. Clinical trials reveal that Lactobacillus fermentum plays important role to microflora balance of mother's milk in mastitis during lactation. Many trials estimating the efficiency of lactobacillus fermentum in prevention and treatment of acute and subacute mastitis have been carried out. The results of them open a new door in front of us in the treatment of these conditions--treatment with probiotics instead of antibiotics. PMID:27514147

    Borrelia burgdorferi infection in beagle dogs was studied quantitatively with skin punch biopsy samples and blood samples collected at 4- and 2-week intervals, respectively, over a 500-day period. Thereafter, 25 tissue samples of each dog were collected for further analysis. Starting at day 120 after tick challenge, 12 dogs were treated with antibiotics (azithromycin, ceftriaxone, or doxycycline) for 30 consecutive days. Four dogs received no antibiotic therapy. Quantification of B. burgdorferi DNA was done with an ABI Prism 7700 Sequence Detection System with oligonucleotide primers and a fluorescence-labeled probe designed to specifically amplify a fragment of the ospA gene of B. burgdorferi strain N40. All 16 dogs became infected with B. burgdorferi after tick challenge. In skin biopsy samples, spirochete numbers peaked at day 60 postinfection (<1.5 x 10(6) organisms per 100 microgram of extracted DNA), at the same time when clinical signs of arthritis developed in 11 of 16 dogs, and decreased to almost undetectable levels during the following 6 months. The number of B. burgdorferi organisms detected in skin biopsy samples was inversely correlated with the antibody levels measured by enzyme-linked immunosorbent assay. Antibiotic treatment reduced the amount of detectable spirochete DNA in skin tissue by a factor of 1,000 or more. At the end of the experiment, B. burgdorferi DNA was detectable at low levels (10(2) to 10(4) organisms per 100 microgram of extracted DNA) in multiple tissue samples regardless of treatment. However, more tissue samples of untreated dogs than of antibiotic-treated dogs were positive, and tissue samples of untreated dogs also were positive by culture. Only 1.6% of 576 blood samples of all dogs were positive for B. burgdorferi by PCR. PMID:10834975

    Purpose. Unilateral treatment with sustained release IGF-1 to one medial rectus muscle in infant monkeys was performed to test the hypothesis that strabismus would develop as a result of changes in extraocular muscles during the critical period of development of binocularity. Methods. Sustained release IGF-1 pellets were implanted unilaterally on one medial rectus muscle in normal infant monkeys during the first 2 weeks of life. Eye position was monitored using standard photographic methods. After 3 months of treatment, myofiber and neuromuscular size, myosin composition, and innervation density were quantified in all rectus muscles and compared to those in age-matched controls. Results. Sustained unilateral IGF-1 treatments resulted in strabismus for all treated subjects; 3 of the 4 subjects had a clinically significant strabismus of more than 10°. Both the treated medial rectus and the untreated ipsilateral antagonist lateral rectus muscles had significantly larger myofibers. No adaptation in myofiber size occurred in the contralateral functionally yoked lateral rectus or in myosin composition, neuromuscular junction size, or nerve density. Conclusions. Sustained unilateral IGF-1 treatment to extraocular muscles during the sensitive period of development of orthotropic eye alignment and binocularity was sufficient to disturb ocular motor development, resulting in strabismus in infant monkeys. This could be due to altering fusion of gaze during the early sensitive period. Serial measurements of eye alignment suggested the IGF-1-treated infants received insufficient coordinated binocular experience, preventing the establishment of normal eye alignment. Our results uniquely suggest that abnormal signaling by the extraocular muscles may be a cause of strabismus. PMID:26030103

    We show the existence of periodic exploding dissipative solitons. These non-chaotic explosions appear when higher-order nonlinear and dispersive effects are added to the complex cubic-quintic Ginzburg-Landau equation modelling soliton transmission lines. This counterintuitive phenomenon is the result of period-halving bifurcations leading to order (periodic explosions), followed by period-doubling bifurcations (or intermittency) leading to chaos (non-periodic explosions).

    Superficial fungal infections are commonly encountered by the physician. And the continuously changing epidemiology of invasive fungal infections results in the need for an expanded armamentarium of antifungal therapies. This study was designed to evaluate the safety and efficacy of Butenafine (BTF) versus Bifonazole (BFZ) in the treatment of superficial mycosis in a randomized, double-blind, parallel-group trial. Of 96 patients, 48 applied (BTF) cream and 48 applied (BFZ) cream for 2 weeks to tinea versicolor, corporis and cruris treat, while tinea of feet & hands was treated for 4 weeks duration. Efficacy was assessed after the end of treatment and 2 weeks later. At the end of therapy, we find somewhat more patients using (BTF) than using (BFZ) had a mycologic cure ((BTF), 87.5%; (BFZ) 83.3%) and effective clinical response ((BTF), 91.7%; (BFZ), 83.3%). (BTF) provides rapid and persistent antifungal activity and symptom relief in patients with superficial mycosis during treatment. And patients continued to improve for at least 2 weeks after treatment. The Rates of mycologic cure and effective treatment with (BTF) were higher than with (BFZ) at cessation of treatment and 2 weeks later. However, no significant difference found between the two drugs (p> 0.05). PMID:23283047

    The effect of 2004 Kawasaki disease (KD) guidelines on diagnosis and outcome of KD is lacking. We studied the epidemiology of KD in our region and compared the incidence, presentation, and outcome of KD before and after publication of the guidelines. A retrospective chart review was conducted for patients admitted with a diagnosis of KD. Demographics, laboratory data, and clinical data were collected. Comparison was made between 2 groups: prepublication (2000-2004) and postpublication (2005-2009) of guidelines. A total of 312 children were included; 64% were African American, 23% White, and 2% Asian; 61% were boys; 79% were complete KD, and 66% were in winter/spring. There was a significant increase in KD cases over the 11 years. There was no significant difference in clinical findings and outcome between the 2 groups. KD admissions in our region significantly increased during the postpublication period. There was no difference in clinical presentation, laboratory findings, or outcome between the 2 groups.

    The periodically oscillating plasma sphere, or POPS, is a novel fusion concept first proposed by D. C. Barnes and R. A. Nebel [Fusion Technol. 38, 28 (1998)]. POPS utilizes the self-similar collapse of an oscillating ion cloud in a spherical harmonic oscillator potential well formed by electron injection. Once the ions have been phase-locked, their coherent motion simultaneously produces very high densities and temperatures during the collapse phase of the oscillation. A requirement for POPS is that the electron injection produces a stable harmonic oscillator potential. This has been demonstrated in a gridded inertial electrostatic confinement device and verified by particle simulation. Also, the POPS oscillation has been confirmed experimentally through observation that the ions in the potential well exhibit resonance behavior when driven at the POPS frequency. Excellent agreement between the observed POPS frequencies and the theoretical predictions has been observed for a wide range of potential well depths and three different ion species. Practical applications of POPS require large plasma compressions. These large compressions have been observed in particle simulations, although space charge neutralization remains a major issue.

    2013-01-01

    Background: Pemphigus is a group of autoimmune blistering diseases of the skin and mucous membranes caused by the presence of antibodies against adhesion molecules on the cell surface of keratinocytes. The possible role of herpes simplex virus infection in the pathogenesis of pemphigus vulgaris (PV) has been suggested. In this study, we evaluated the impact of a course of acyclovir in improvement of the pemphigus patients and reduction of the hospitalization duration. Materials and Methods: A total of 30 patients with definitive diagnosis of PV were recruited in study. They were randomized in two groups. One group received routine treatment and another received the routine plus 2 week course of oral acyclovir (1200 mg/day). The improvement was defined as a more than 50% change in baseline severity score of the disease. All data was registered at the checklists and after follow-up period, the statistical analyses were performed by aid of t-test and Fisher's exact test. Results: There was no statistically significant difference in mean severity score and improvement rates between two groups at the end of study (P > 0.05). Meanwhile, there was no statistical difference in duration of hospitalization in two groups (P > 0.05) though the severity score and hospitalization duration were apparently less in acyclovir-group than control group. Neither of the patients (in acyclovir group) showed any side effect. Conclusion: We did not observe any difference between response to treatment and hospitalization period in the group that was treated with acyclovir as compared with control group. However, the partial and complete remissions were higher in patients on acyclovir therapy compared to controls. In those pemphigus patients who do not respond to sufficient immunosuppressive regimen or show a sudden relapse after reaching partial or complete clinical remission, a trial of oral acyclovir therapy may have promising result.

    The standard treatment for ambulatory patients with venous ulcers is compression therapy. The aim of the present study was to develop a warming regimen to treat venous ulcers, which could be easily used by patients in their home or work environment. Five patients with a mean age of 66 years (51-80) who had venous ulcers for an average of 8 months (3-13) were treated with zip-up compression stockings (gradient compression 40 mmHg at the ankle) and a warming dressing. The latter was controlled by the patient to warm the ulcer to 38 degrees C for 1 hour three times daily. Warming therapy was carried out for 2 weeks and patients' ulcers were monitored for healing for 12 weeks. In all but one of the patients following warming therapy, there was marked increase in granulation tissue as well as a decrease in pain. Four of the five patients completely healed during the 12-week period. In conclusion, this study has demonstrated that warming therapy can be used by ambulatory patients with venous ulcers in conjunction with compression therapy. A randomized prospective study is in progress. PMID:10655876

    Background: The carpal tunnel syndrome (CTS) is the most common neuropathy. The aim of this study was to evaluate the effect of a new and noninvasive treatment including extracorporeal shock wave therapy (ESWT) in the treatment of CTS. Materials and Methods: This study is a clinical trial conducted on 60 patients with moderate CTS in selected health centers of Isfahan Medical University from November 2014 to April 2015. Patients with CTS were randomly divided into two groups. Conservative treatment including wrist splint at night for 3 months, consumption of nonsteroidal anti-inflammatory drugs for 2 weeks, and oral consumption of Vitamin B1 for a month was recommended for both groups. The first group was treated with ESWT, one session per week for 4 weeks. Focus probe with 0.05, 0.07, 0.1, and 0.15 energy and shock numbers 800, 900, 1000, and 1100 were used from the first session to the fourth, respectively. The evaluated parameters were assessed before treatment and after 3 and 6 months. Data were analyzed using SPSS version 19, Student’s t-test, and Chi-square test. Results: All parameters were significantly decreased in the ESWT group after 3 months. These results remained almost constant after 6 months compared with 3 months after treatment. However, only two parameters considerably improved after 3 months of treatment in the control group. The entire indexes in the control group implicated the regression of results in long-term period. Conclusion: It is recommended to use ESWT as a conservative treatment in patients with CTS. PMID:27563630

    Injury to axons close to the neuronal bodies in the mammalian central nervous system causes a large proportion of parenting neurons to degenerate. It is known that optic nerve transection close to the eye in rodents leads to a loss of about half of retinal ganglion cells in 1 week and about 90% in 2 weeks. Using low level laser treatment in the present study, we demonstrated that treatment with helium-neon (660 nm) laser with 15 mW power could delay retinal ganglion cell death after optic nerve axotomy in adult hamsters. The effect was most apparent in the first week with a short period of treatment time (5 minutes) in which 65-66% of retinal ganglion cells survived the optic nerve axotomy whereas 45-47% of retinal ganglion cells did so in optic nerve axotomy controls. We also found that single dose and early commencement of laser irradiation were important in protecting retinal ganglion cells following optic nerve axotomy. These findings thus convincingly show that appropriate laser treatment may be neuroprotective to retinal ganglion cells. PMID:25558230

    Background: Lifa disease (frictional dermal melanosis) is a common dermatological problem. Full strength lactic acid has been proved to be effective and safe peeling agent in the treatment of melasma. Objective: To assess the effectiveness and the safety of lactic acid chemical peeling in the treatment of lifa disease. Materials and Methods: This open label therapeutic trial was conducted in Department of Dermatology in Najaf and Baghdad Teaching Hospitals, from March 2007-October 2008. Full strength lactic acid (92%, pH 3.5) was used as a peeling agent. The treatment sessions were done every 2 weeks until the desired response was achieved (but not more than 6 sessions). The response to therapy was evaluated by objective and subjective methods. All patients were followed monthly for 3 months after the last treatment session. Results: 52 patients with typical clinical features of lifa disease were included. All patients were slim with prominent bones and low body mass index, and gave history of using the lifa (washing agent) during bathing. The number of sessions ranged from 2-6 sessions. The pigmentation was improved in all patients as revealed by objective and subjective methods, and this response was statistically highly significant. No significant side effects were recorded in all treated patients. The improvement has been sustained without any obvious relapse throughout the follow-up period. Conclusion: Lactic acid peel is a new, non-costly mode of therapy in treating dermal melanosis in patients with lifa disease. PMID:23248362

    Results are presented of a detailed period study of the eclipsing binary system SZ Arietis, based on up-to-date collection of minima. A new period (P = 1.7175405 d) of the SZ Ari was found, and the period changes (with the new period) in different portions of the O-C diagram were estimated. The average period change (leaving out an unusual value) was estimated to be about 0.00006 d. The O-C diagram displayed a sinusoidal variation, indicating that the SZ Ari system may be a three-body system, having a period of nearly 66 years.

    Abstract This study determined the effects of intraperitoneal sodium pyruvate (SP) treatment on the levels of circulating fuels and on cerebral microdialysis levels of glucose (MDglc), lactate (MDlac), and pyruvate (MDpyr), and the effects of SP treatment on neuropathology after left cortical contusion injury (CCI) in rats. SP injection (1000 mg/kg) 5 min after sham injury (Sham-SP) or CCI (CCI-SP) significantly increased arterial pyruvate (p < 0.005) and lactate (p < 0.001) compared to that of saline-treated rats with CCI (CCI-Sal). Serum glucose also increased significantly in CCI-SP compared to that in CCI-Sal rats (p < 0.05), but not in Sham-SP rats. MDpyr was not altered after CCI-Sal, whereas MDlac levels within the cerebral cortex significantly increased bilaterally (p < 0.05) and those for MDglc decreased bilaterally (p < 0.05). MDpyr levels increased significantly in both Sham-SP and CCI-SP rats (p < 0.05 vs. CCI-Sal) and were higher in left/injured cortex of the CCI-SP group (p < 0.05 vs. sham-SP). In CCI-SP rats the contralateral MDlac decreased below CCI-Sal levels (p < 0.05) and the ipsilateral MDglc levels exceeded those of CCI-Sal rats (p < 0.05). Rats with a single low (500 mg/kg) or high dose (1000 mg/kg) SP treatment had fewer damaged cortical cells 6 h post-CCI than did saline-treated rats (p < 0.05), but three hourly injections of SP (1000 mg/kg) were needed to significantly reduce contusion volume 2 weeks after CCI. Thus, a single intraperitoneal SP treatment increases circulating levels of three potential brain fuels, attenuates a CCI-induced reduction in extracellular glucose while increasing extracellular levels of pyruvate, but not lactate, and can attenuate cortical cell damage occurring within 6 h of injury. Enduring (2 week) neuronal protection was achieved only with multiple SP treatments within the first 2 h post-CCI, perhaps reflecting the need for additional fuel throughout the

    Objectives There are very little data on pre-excitation syndrome (PS) in the elderly. We investigated the influence of advancing age on clinical presentation, treatment and long-term outcome of PS. Setting Single-centre retrospective study of patient files. Participants In all, 961 patients (72 patients ≥60 years (mean 68.5±6), 889 patients <60 years (mean 30.5±14)) referred for overt pre-excitation and indication for electrophysiological study (EPS) were followed for 5.3±5 years. Usual care included 24 h Holter monitoring, echocardiography and EPS. Patients underwent accessory pathway (AP) ablation if necessary. Primary and secondary outcome measures Occurrence of atrial fibrillation (AF) or procedure-induced adverse event. Results Electrophysiological data and recourse to AP ablation (43% vs 48.5%, p=0.375) did not significantly differ between the groups. Older patients more often had symptomatic forms (81% vs 63%, p=0.003), history of spontaneous AF (8% vs 3%, p=0.01) or adverse presentation (poorly tolerated arrhythmias: 18% vs 7%, p=0.0009). In multivariable analysis, patients ≥60 years had a significantly higher risk of history of AF (OR=4.2, 2.1 to 8.3, p=0.001) and poorly tolerated arrhythmias (OR=3.8, 1.8 to 8.1, p=0.001). Age ≥60 years was associated with an increased major AP ablation complication risk (10% vs 1.9%, p=0.006). During follow-up, occurrence of AF (13.9% vs 3.6%, p<0.001) and incidence of poorly tolerated tachycardia (4.2% vs 0.6%, p=0.001) were more frequent in patients ≥60 years, although frequency of ablation failure or recurrence was similar (20% vs 15.5%, p=0.52). In multivariable analysis, patients ≥60 years had a significantly higher risk of AF (OR=2.9, 1.2 to 6.8, p≤0.01). Conclusions In this retrospective monocentre study, patients ≥60 years referred for PS work up appeared at higher risk of AF and adverse presentation, both prior and after the work up. These results suggest that, in elderly

    Periodic structures are well known in various branches of physics for their ability to provide a stopband. In this article, using optical periodic structures we showed that, when a second periodicity – very closed to the original periodicity is introduced, large number of states appears in the stopband corresponding to the first periodicity. In the limit where the two periods matches, we have a continuum of states, and the original stopband completely disappears. This intriguing phenomena is uncovered by noticing that, regardless of the proximities of the two periodicities, there is an array of spatial points where the dielectric functions corresponding to the two periodicities interfere destructively. These spatial points mimic photonic atoms by satisfying the standards equations of quantum harmonic oscillators, and exhibit lossless, atom-like dispersions. PMID:26853945

    Cholestasis results from impairment in the excretion of bile, which may be due to mechanical obstruction of bile flow or impairment of excretion of bile components into the bile canaliculus. When present, cholestasis warrants prompt diagnosis and treatment. The differential diagnosis of cholestasis beyond the neonatal period is broad and includes congenital and acquired etiologies. It is imperative that the clinician differentiates between intrahepatic and extrahepatic origin of cholestasis. Treatment may be supportive or curative and depends on the etiology. Recent literature shows that optimal nutritional and medical support also plays an integral role in the management of pediatric patients with chronic cholestasis. This review will provide a broad overview of the pathophysiology, diagnostic approach, and management of cholestasis beyond the neonatal and infancy periods. PMID:27066444

    Cholestasis results from impairment in the excretion of bile, which may be due to mechanical obstruction of bile flow or impairment of excretion of bile components into the bile canaliculus. When present, cholestasis warrants prompt diagnosis and treatment. The differential diagnosis of cholestasis beyond the neonatal period is broad and includes congenital and acquired etiologies. It is imperative that the clinician differentiates between intrahepatic and extrahepatic origin of cholestasis. Treatment may be supportive or curative and depends on the etiology. Recent literature shows that optimal nutritional and medical support also plays an integral role in the management of pediatric patients with chronic cholestasis. This review will provide a broad overview of the pathophysiology, diagnostic approach, and management of cholestasis beyond the neonatal and infancy periods. PMID:27066444

    This article describes the results of an independent small-scale trial with the centrally acting agent bupropion for female hypoactive sexual desire disorder. The main goals were to gain insight into the intrapsychic and interpersonal barriers to improvement associated with the pharmacological treatment of this common disorder. Eligible subjects entered a 2-week run-in period and a 4-week placebo phase, followed by a 20-week treatment phase. In addition to semi-structured clinical interviews and a set of standardized questionnaires, we used 2 self-developed questionnaires, addressing the period between visits and the week preceding each visit. Participants were 16 women who entered the placebo phase and 10 who completed the medication period. Analyses of pre-post scores and of the questionnaire addressing the time between visits yielded no significant changes. The questionnaire focusing on the week preceding each visit indicated improvements in sexual desire, arousability, and orgasmic ease after Week 8. In the clinical interviews, half of the women reported subjective improvements of sexual desire and arousability that could not be transferred to the sexual relationship as a result of individual and dyadic barriers. Overall, a centrally acting agent such as bupropion may be a viable option for female sexual dysfunction, but it seems mandatory to embed it in a psychotherapeutic approach. PMID:22712818

    (Abstract only) Betelgeuse was studied using the VSTAR software package and analysis of the observations in the AAVSO database. Period analysis derived a period of 376 days, in comparison with literature periods of 420 days using satellite UV data but significantly different from the VSX period of 2,335 days. The unique set of PEP observations of this star is also shown and advantage of PEP Johnson V observations is shown in comparison with the visual observations.

    Although the carbonic anhydrase inhibitors have been used in the treatment of the primary periodic paralyses (PPs), their efficacy has not been demonstrated in double-blind, placebo-controlled trials. Therefore, we tested the efficacy of dichlorphenamide (DCP; Daranide), a potent carbonic anhydrase inhibitor, in the treatment of episodic weakness in the primary PPs. We performed two multicenter, randomized, double-blind, placebo-controlled crossover trials, one involving 42 subjects with hypokalemic periodic paralysis (HypoPP) and the other involving 31 subjects with potassium-sensitive periodic paralysis (PSPP). In each trial, two 8-week treatment periods were separated by an active washout period of at least 9 weeks. The primary outcome variable in the HypoPP trial was the occurrence of an intolerable increase in attack severity or frequency (end point). The primary outcome variable in the PSPP trial was the number of attacks per week. In the HypoPP trial, there were 13 subjects who exhibited a preference (in terms of the end point) for either DCP or placebo, and 11 of these preferred DCP. In the PSPP trial, DCP significantly reduced attack rates relative to placebo. DCP also significantly reduced attack rates relative to placebo in the HypoPP subjects. We conclude that DCP is effective in the prevention of episodic weakness in both HypoPP and PSPP. PMID:10632100

    In this Letter, for a general class of delayed periodic Lotka-Volterra systems, we prove some new results on the existence of positive periodic solutions by Schauder's fixed point theorem. The global asymptotical stability of positive periodic solutions is discussed further, and conditions for exponential convergence are given. The conditions we obtained are weaker than the previously known ones and can be easily reduced to several special cases.

    Cubick, Erin E.; Quezada, Vanessa Y.; Schumer, Ariel D.; Davis, Carol M.

    2011-01-01

    Background: Myofascial release (MFR) is a manual therapeutic technique used to release fascial restrictions, which may cause neuromusculoskeletal and systemic pathology. Purpose: This case report describes the use of sustained release MFR techniques in a patient with a primary diagnosis of rheumatoid arthritis (RA) and a secondary diagnosis of collagenous colitis. Changes in pain, cervical range of motion, fatigue, and gastrointestinal tract function, as well as the impact of RA on daily activities, were assessed. Methods: A 54-year-old white woman presented with signs and symptoms attributed to RA and collagenous colitis. Pre and post measurements were taken with each treatment and during the interim between the initial and final treatment series. The patient recorded changes in pain, fatigue, gastrointestinal tract function, and quality of life. Cervical range of motion was assessed. Six sustained release MFR treatment sessions were provided over a 2-week period. Following an 8-week interim, two more treatments were performed. Results: The patient showed improvements in pain, fatigue, gastrointestinal tract function, cervical range of motion, and quality of life following the initial treatment series of six sessions. The patient maintained positive gains for 5 weeks following the final treatment, after which her symptoms returned to near baseline measurements. Following two more treatments, positive gains were achieved once again. Conclusions: In a patient with RA and collagenous colitis, the application of sustained release MFR techniques in addition to standard medical treatment may provide short-term and long-term improvements in comorbid symptoms and overall quality of life.

    2016-04-01

    We study the dynamics and the phase-space structures of Coulombic and self-gravitating versions of the classical one-dimensional three-body system with periodic boundary conditions. We demonstrate that such a three-body system may be reduced isomorphically to a spatially periodic system of a single particle experiencing a two-dimensional potential on a rhombic plane. For the case of both Coulombic and gravitational versions, exact expressions of the Hamiltonian have been derived in rhombic coordinates. We simulate the phase-space evolution through an event-driven algorithm that utilizes analytic solutions to the equations of motion. The simulation results show that the motion exhibits chaotic, quasiperiodic, and periodic behaviors in segmented regions of the phase space. While there is no evidence of global chaos in either the Coulombic or the gravitational system, the former exhibits a transition from a completely nonchaotic phase space at low energies to a mixed behavior. Gradual yet striking transitions from mild to intense chaos are indicated with changing energy, a behavior that differentiates the spatially periodic systems studied in this Rapid Communication from the well-understood free-boundary versions of the three-body problem. Our treatment of the three-body systems opens avenues for analysis of the dynamical properties exhibited by spatially periodic versions of various classes of systems studied in plasma and gravitational physics as well as in cosmology.

    For several years before equinox, the energetic charged and neutral particles in Saturn’s magnetosphere displayed strong periodicities near 10.8 hours, the same period observed in radio emissions and magnetic fields. These particle periodicities have now been observed at equinox in electrons, protons, oxygen ions, and neutral hydrogen and oxygen atoms at all energies greater than ~3 keV, the lowest energies measured by the Magnetospheric IMaging Instrument (MIMI) on the Cassini spacecraft. The equinoctial electrons exhibit a very strong period at 10.72 hours, while the protons have essentially no periodicity at all. Water group ions display a notable period at 10.73 hours. Both the electrons and the ions have curious overtones in their spectral structure that may be related to solar wind modulation. The energetic neutral hydrogen and oxygen atoms have strong periods of 10.79 hours at equinox. Within the uncertainties of the measurements, the ENA periods are slightly longer than the charged particle periods, although they cover a somewhat different time interval. For comparison, the Cassini magnetometer observed periodicities in Saturn’s magnetic field of 10.65 hours during the same equinoctial interval. These observations will be interpreted in terms of a wavy magnetodisk model.

    Interruption of combination antiretroviral therapy in HIV-1-infected individuals leads to rapid viral rebound. Here we report the results of a phase IIa open label clinical trial evaluating 3BNC117,a broad and potent neutralizing antibody against the CD4 binding site of the HIV-1 Env protein, during analytical treatment interruption in 13 HIV-1-infected individuals. Participants with 3BNC117-sensitive virus outgrowth cultures were enrolled. Results show that two or four 30 mg kg(-1) 3BNC117 infusions,separated by 3 or 2 weeks, respectively, are generally well tolerated.Infusions are associated with a delay in viral rebound of 5-9 weeks after two infusions, and up to 19 weeks after four infusions, or an average of 6.7 and 9.9 weeks, respectively, compared with 2.6 weeks for historical controls (P < 0.00001). Rebound viruses arise predominantly from a single provirus. In most individuals,emerging viruses show increased resistance, indicating escape.However, 30% of participants remained suppressed until antibody concentrations waned below 20 μg ml(-1), and the viruses emerging in all but one of these individuals showed no apparent resistance to 3BCN117, suggesting failure to escape over a period of 9-19 weeks.We conclude that the administration of 3BNC117 exerts strong selective pressure on HIV-1 emerging from latent reservoirs during analytical treatment interruption in humans.

  15. On the Period-Amplitude and Amplitude-Period Relationships

    NASA Technical Reports Server (NTRS)

    Wilson, Robert M.; Hathaway, David H.

    2008-01-01

    Examined are Period-Amplitude and Amplitude-Period relationships based on the cyclic behavior of the 12-month moving averages of monthly mean sunspot numbers for cycles 0.23, both in terms of Fisher's exact tests for 2x2 contingency tables and linear regression analyses. Concerning the Period-Amplitude relationship (same cycle), because cycle 23's maximum amplitude is known to be 120.8, the inferred regressions (90-percent prediction intervals) suggest that its period will be 131 +/- 24 months (using all cycles) or 131 +/- 18 months (ignoring cycles 2 and 4, which have the extremes of period, 108 and 164 months, respectively). Because cycle 23 has already persisted for 142 months (May 1996 through February 2008), based on the latter prediction, it should end before September 2008. Concerning the Amplitude-Period relationship (following cycle maximum amplitude versus preceding cycle period), because cycle 23's period is known to be at least 142 months, the inferred regressions (90-percent prediction intervals) suggest that cycle 24's maximum amplitude will be about less than or equal to 96.1 +/- 55.0 (using all cycle pairs) or less than or equal to 91.0 +/- 36.7 (ignoring statistical outlier cycle pairs). Hence, cycle 24's maximum amplitude is expected to be less than 151, perhaps even less than 128, unless cycle pair 23/24 proves to be a statistical outlier.

    ST Puppis is a reasonably bright W Virginis variable star, a Type 2 Cepheid with a record of substantial and erratic period changes—21 during the interval 1900 to 1985 with a range of magnitude from 17.4 to 19.2. It was observed as part of Variable Stars South's Cepheid project by Butterworth in 2014 and 2015 using DSLR photometry in BGR passbands and visually by Pearce in 2015. The known period changes are shown graphically and doubtful ones examined and discarded if necessary. With its period and amplitude with a frequently changing period it is a suitable and worthwhile object for visual observing.

Steady resolution of the infiltrate was noted within 2 weeks of therapy. PMID:18417831

  19. Periodic and aperiodic synchronization in skilled action.

    PubMed

    Cummins, Fred

    2011-01-01

    Synchronized action is considered as a manifestation of shared skill. Most synchronized behaviors in humans and other animals are based on periodic repetition. Aperiodic synchronization of complex action is found in the experimental task of synchronous speaking, in which naive subjects read a common text in lock step. The demonstration of synchronized behavior without a periodic basis is presented as a challenge for theoretical understanding. A unified treatment of periodic and aperiodic synchronization is suggested by replacing the sequential processing model of cognitivist approaches with the more local notion of a task-specific sensorimotor coordination. On this view, skilled action is the imposition of constraints on the co-variation of movement and sensory flux such that the boundary conditions that define the skill are met. This non-cognitivist approach originates in the work of John Dewey. It allows a unification of the treatment of sensorimotor synchronization in simple rhythmic behavior and in complex skilled behavior and it suggests that skill sharing is a uniquely human trait of considerable import.

  1. Quasi-periodicity in relative quasi-periodic tori

    Fassò, Francesco; García-Naranjo, Luis C.; Giacobbe, Andrea

    2015-10-01

    At variance from the cases of relative equilibria and relative periodic orbits of dynamical systems with symmetry, the dynamics in relative quasi-periodic tori (namely, subsets of the phase space that project to an invariant torus of the reduced system on which the flow is quasi-periodic) is not yet completely understood. Even in the simplest situation of a free action of a compact and abelian connected group, the dynamics in a relative quasi-periodic torus is not necessarily quasi-periodic. It is known that quasi-periodicity of the unreduced dynamics is related to the reducibility of the reconstruction equation, and sufficient conditions for it are virtually known only in a perturbation context. We provide a different, though equivalent, approach to this subject, based on the hypothesis of the existence of commuting, group-invariant lifts of a set of generators of the reduced torus. Under this hypothesis, which is shown to be equivalent to the reducibility of the reconstruction equation, we give a complete description of the structure of the relative quasi-periodic torus, which is a principal torus bundle whose fibers are tori of a dimension which exceeds that of the reduced torus by at most the rank of the group. The construction can always be done in such a way that these tori have minimal dimension and carry ergodic flow.

  2. Diagnostic irradiation of women during the reproductive period.

    The date of onset of the last menstrual period should be given on radiographic requisitions for all women of reproductive age. Every effort should be made to avoid unnecessary irradiation of any woman who might be pregnant. Radiation damage in the first 2 weeks of pregnancy, however, should be "all or none", resulting in either a miscarriage or a normal child. Diagnostic radiology procedures are not indications for therapeutic abortion. Ultrasound has now replaced ionizing radiation in most examinations of the fetus and placenta. Pelvimetry should be done only when the decision to do a cesarean section hinges on precise knowledge of measurements of the bony pelvis. On the rare occasion when a radiograph of the fetus is necessary the woman should be prone for the examination. All such examinations are best ordered after consultation with a radiologist. Radiography of distant areas with the beam directed away from the woman's abdomen can be done without concern at any stage of pregnancy. Images FIG. 1A FIG. 1B PMID:902213

  6. Testing for periodicity of extinction

    1988-01-01

    The statistical techniques used by Raup and Sepkoski (1984 and 1986) to identify a 26-Myr periodicity in the biological extinction record for the past 250 Myr are reexamined, responding in detail to the criticisms of Stigler and Wagner (1987). It is argued that evaluation of a much larger set of extinction data using a time scale with 51 sampling intervals supports the finding of periodicity. In a reply by Sigler and Wagner, the preference for a 26-Myr period is attributed to a numerical quirk in the Harland et al. (1982) time scale, in which the subinterval boundaries are not linear interpolations between the stage boundaries but have 25-Myr periodicity. It is stressed that the results of the stringent statistical tests imposed do not disprove periodicity but rather indicate that the evidence and analyses presented so far are inadequate.

    2004-01-01

    This paper generalizes and extends the concept of the Schuler oscillation that occurs in the theory of inertial navigation systems, allowing one to see how the Schuler phenomenon affects inertial navigation systems operating in space. We show why a low earth orbit satellite's orbital period is identical to the period of the Schuler pendulum, which is the period of the errors for terrestrial inertial navigation systems. We also show that the generalized form of the Schuler oscillation takes the same form as the Hill-Clohessy-Wiltshire equations for satellite relative motion and that the period of the out-of-plane motion in neighboring satellite relative trajectories is the same as the Schuler period. Finally, we describe how INS gyro drift manifests itself in different coordinate systems for the orbital case. These results may assist orbital flight dynamics and attitude control systems engineers in the design and analysis of INS-equipped spacecraft

  8. Rationalization of Comet Halley's periods

    NASA Astrophysics Data System (ADS)

    Belton, M. J. S.

    1990-07-01

    The sense of long axis orientation of Comet Halley during the Vega 1 encounter must be reversed from that deduced by Sagdeev et al. (1986) in order to harmonize the comet nucleus' Vega/Giotto-observed orientations with periodicities extracted from time-series brightness data. It is also demonstrated that Vega/Giotto observations can be satisfied by either a 2.2- or 3.7-day long-axis free precession period. A novel Fourier algorithm is used to reanalyze five independent data sets; strong evidence is adduced for periods harmonically related to a 7.4-day period. The preferred candidate models for Halley's nuclear rotation are characterized by a long-axis precession period of 3.7 days.

  9. LYRA Mid-Term Periodicities

    2016-08-01

    The spectra of the PROBA2/LYRA data, similarly to every other solar time series, show predominant periodicities that can be of solar or instrumental origin. In this article, we compare the main periodicities characterizing the LYRA spectrum to those found in the sunspot number, in the 10.7 cm flux, in an X-ray flare index, and in the sunspot area evolution. We focused on the 2010 to 2014 time range, for which the LYRA data are available, although we also briefly address the evolution of the main periodicities in the longer range. The mid-term periodicities at {˜} 28, {˜} 44, {˜} 54, {˜} 59, {˜} 100, {˜} 110, and {˜} 150 days appear as highly significant in several analyzed datasets. The consistency of distinct periodicities between datasets provides characteristics for the global Sun. This consistency also strengthens the reliability of LYRA data.

  10. Incorporating Spectra Into Periodic Timing

    NASA Astrophysics Data System (ADS)

    Connors, Alanna; Hong, J.; Protopapas, P.; Kashyap, V.

    2011-09-01

    The Chandra surveys have resulted in a wealth of data on low-luminosity X-ray sources (Lx 1030-34 erg/s) of Galactic scales beyond the local solar neighborhood. Many of these are compact binaries, in particular, cataclysmic variables, often identified by their periodic X-ray variability and spectra. Hong et al. (2009, 2011) have used energy quantiles (Hong, Schlegel & Grindlay, 2004) as a fast, robust indicator of spectral hardness and absorption of the X-ray sources. Energy quantiles also enable a simple but effective illustration of spectral changes with phase in these periodic systems: e.g. absorption by the accreting material is understood to drive the periodic light-curves. An interesting question is how to best make use of the information encapsulated in the periodic change in energy spectrum, along with the periodic change in intensity, especially for cases of ambiguous period determination? And, how to do it computationally efficiently? A first approach is to do the period search in intensity, as is standard; and then use a criterion of spectral variation to verify possible periods. Huijse, Zegers & Protopapas (2011) recently demonstrated a powerful period estimation technique using information potential and correntropy embedded in the light curve. Similar quantities based on energies (or energy quantiles) of X-ray photons can serve as criteria of spectral variation. A different approach treats the spectrum variations and intensity variations completely independently, searching through period-space in each, and then combining the results. A more general method would include both at the same time, looking for statistically significant variations above what is expected for a constant (in intensity and spectrum).

    Background Core podiatry involves treatment of the nails, corns and callus and also giving footwear and foot health advice. Though it is an integral part of current podiatric practice little evidence is available to support its efficacy in terms of research and audit data. This information is important in order to support the current NHS commissioning process where services are expected to provide data on standards including outcomes. This study aimed to increase the evidence base for this area of practice by conducting a multi-centre audit in 8 NHS podiatry departments over a 1-year period. Methods The outcome measure used in this audit was the Podiatry Health Questionnaire which is a self completed short measure of foot health including a pain visual analogue scale and a section for the podiatrist to rate an individual's foot health based on their podiatric problems. The patient questionnaire was completed by individuals prior to receiving podiatry care and then 2 weeks after treatment to assess the effect of core podiatry in terms of pain and foot health. Results 1047 patients completed both questionnaires, with an age range from 26–95 years and a mean age of 72.9 years. The podiatrists clinical rating at baseline showed 75% of patients had either slight or moderate podiatric problems. The differences in questionnaire and visual analogue scores before and after treatment were determined according to three categories – better, same, worse and 75% of patients' scores either remained the same or improved after core podiatry treatment. A student t-test showed a statistical significant difference in pre and post treatment scores where P < 0.001, though the confidence interval indicated that the improvement was relatively small. Conclusion Core podiatry has been shown to sustain or improve foot health and pain in 75% of the patients taking part in the audit. Simple outcome measures including pain scales should be used routinely in podiatric practice to assess the

    Human scabies is caused by an infestation of the skin by the human itch mite (Sarcoptes scabiei va. hominis). It is commonly treated with topical insecticides, but the treatment of choice is still controversial. The aim of this study is to compare the efficacy of topical ivermectin vs. permethrin 2.5% cream for the treatment of scabies. In total, 380 patients with scabies were enrolled, and randomized into two groups: the first group received 1% ivermectin applied topically to the affected skin at a dose of 400 microg/kg, repeated once the following week, while the second group received permethrin 2.5% cream and were told to apply this twice at one week intervals. Treatment was evaluated at intervals of 2 and 4 weeks, and if there was treatment failure at the 2-week follow-up, treatment was repeated. Two applications of topical ivermectin provided a cure rate of 63.1% at the 2-week follow-up, which increased to 84.2% at the 4-week follow-up after repeating the treatment. Treatment with two applications of permethrin 2.5% cream with a 1-week interval between them was effective in 65.8% of patients at the 2-week follow-up, which increased to 89.5% at the 4-week follow-up after this treatment was repeated. Two application of ivermectin was as effective as two applications of permethrin 2.5% cream at the 2-week follow-up. After repeating the treatment, ivermectin was as effective as permethrin 2.5% cream at the 4-week follow up. PMID:24171301

    Scabies, known colloquially as the 7-year itch, is a contagious skin infection that occurs among humans and other animals. The treatment of choice is still controversial. The aim of this study was to compare the efficacy and safety of topical ivermectin vs. crotamiton cream 10% for the treatment of scabies. In total, 340 patients with scabies were enrolled, and randomized into two groups. The first group received 1% ivermectin applied topically to the affected skin. The dose employed was 400 μg/kg, repeated once the following week, and the second group received crotamiton 10% cream and were told to apply this twice daily for five consecutive days. Treatment was evaluated at intervals of two and four weeks, and if there was treatment failure at the 2-week follow-up, treatment was repeated. Two applications of topical ivermectin provided a cure rate of 64.7% at the 2-week follow-up, which increased to 82.3% at the 4-week follow-up after repeating the treatment. Treatment with single applications of crotamiton cream 10% was effective in 41.2% of patients at the 2-week follow-up, which increased to 64.7% at the 4-week follow-up after this treatment was repeated. Ivermectin was quite safe in our cases. Two applications of ivermectin were as effective as single applications of crotamiton 10% cream at the 2-week follow-up. After repeating the treatment, ivermectin was superior to crotamiton cream 10% at the 4-week follow-up. PMID:24898622

    Human scabies is caused by an infection of the skin by the human itch mite (Sarcoptes scabiei var. hominis). There are different medications for the treatment of scabies. This study aimed at comparing the efficacy and safety of oral ivermectin vs. sulfur 10% ointment for the treatment of scabies. In total, 420 patients with scabies were enrolled, and randomized into two groups: the first group received a single dose of oral ivermectin 200 μg/kg body weight, and the second group received sulfur 10% ointment and were told to apply this for three successive days. Treatment was evaluated at intervals of 2 and 4 weeks, and if there was treatment failure at the 2-week follow-up, treatment was repeated. A single dose of ivermectin provided a cure rate of 61.9% at the 2-week follow-up, which increased to 78.5% at the 4-week follow-up after repeating the treatment. Treatment with single applications of sulfur 10% ointment was effective in 45.2% of patients at the 2-week follow-up, which increased to 59.5% at the 4-week follow-up after this treatment was repeated. A single dose of ivermectin was as effective as single applications of sulfur 10% ointment at the 2-week follow-up. After repeating the treatment, ivermectin was superior to sulfur 10% ointment at the 4-week follow up. The delay in clinical response with ivermectin suggests that it may not be effective against all the stages in the life cycle of the parasite. . PMID:26342502

    Background: Cryosurgery is one of the simplest, most effective gingival depigmentation methods. Repigmentation may happen after a while in each method. The aim of this study is to compare the recurrence rate after treatment by liquid nitrogen swap and a cryoprob in 18 months. Materials and Methods: A total of 26 patients with physiologic gingival pigmentation were selected. The anterior sextant was divided into left and right segments; each segment was treated randomly by swap technique or cryoprob. Standard photos were evaluated with photoshop software (Red, Green, Blue, Cyan, Magenta, Yellow, Black [RGB, CMYK]) before and at 2 week, 1, 3, 6, 9, 12, 15, 18 months after the treatment. The results were compared, by the independent t-test and repeated measure ANOVA thereafter least significant difference post-hoc. The viewpoints of patients and physicians regarding the treatment outcomes were obtained by a questionnaire and consequently evaluated qualitatively by McNemar test (P < 0.05 was considered as significant level). Results: The statistical analysis showed a significant difference in color change after the treatment during 18 months, in each group (P < 0.001). The mean values of RGB had significantly increased after 2 weeks in both methods (P < 0.001), but the differences from 2 weeks to 18 months after treatment were not significant (P > 0.05). The mean values of CMYK significantly decreased after 2 weeks in both methods (P < 0.001), but the differences from 2 weeks to 18 months after treatment were not significant (P > 0.05). Qualitative evaluation showed the preference of the cryosurgery with swap method (P < 0.001). No significant recurrence was observed during 18 months follow-up. Conclusion: Both methods of cryosurgery are appropriate in treatment of gingival depigmentation because no significant recurrence was observed during 18 months follow-up. PMID:25426152

  17. Chaos in Periodic Discrete Systems

    NASA Astrophysics Data System (ADS)

    Shi, Yuming; Zhang, Lijuan; Yu, Panpan; Huang, Qiuling

    This paper focuses on chaos in periodic discrete systems, whose state space may vary with time. Some close relationships between some chaotic dynamical behaviors of a periodic discrete system and its autonomous induced system are given. Based on these relationships, several criteria of chaos are established and some sufficient conditions for no chaos are given for periodic discrete systems. Further, it is shown that a finite-dimensional linear periodic discrete system is not chaotic in the sense of Li-Yorke or Wiggins. In particular, an interesting problem of whether nonchaotic rules may generate a chaotic system is studied, with some examples provided, one of which surprisingly shows that a composition of globally asymptotically stable maps can be chaotic. In addition, some properties of sign pattern matrices of non-negative square matrices are given for convenience of the study.

    Perinatal substance use remains a major public health problem and is associated with a number of deleterious maternal and fetal effects. Polysubstance use in pregnancy is common and can potentiate adverse maternal and fetal outcomes. Tobacco is the most commonly used substance in pregnancy, followed by alcohol and illicit substances. The treatments for perinatal substance use are limited and consist mostly of behavioral and psychosocial interventions. Of these, contingency management has shown the most efficacy. More recently, novel interventions such as progesterone for postpartum cocaine use have shown promise. The purpose of this review is to examine the recent literature on the use of tobacco, alcohol, cannabis, stimulants, and opioids in the perinatal period, their effects on maternal and fetal health, and current treatments.

    Chronotherapeutics such as wake therapy and bright light therapy are well-established methods in treating adults with depressive disorders and are additionally beneficent for sleep regulation. Few studies concerning chronotherapeutics in juvenile depression exist, though the established treatments are insufficient and sleep disorders often co-occur. In this study, we investigate the impact of two types of chronotherapeutics on depressive symptoms and sleep behavior in a juvenile setting. Juvenile inpatients (n = 62) with moderate to severe depressive symptoms took part in either a combined setting consisting of one night wake therapy followed by 2 weeks bright light therapy or in a setting of bright light therapy alone. Depressive symptoms, general psychopathology, clinical impression and sleep behavior were measured before (T1), directly after (T2) and 2 weeks after intervention (T3). Depressive symptoms decreased while sleep quality increased in both groups. The bright light therapy alone group showed further improvement at T3 in regards to depressive symptoms. Correlation analyses indicated significant negative correlations between sleep quality and awaking after restorative sleep with the depressive symptoms. However, only awaking after restorative sleep had a predictive impact on treatment outcome. The present study provides first evidence for a positive impact of chronotherapeutic interventions on treatment outcome in depressed juvenile inpatients. Bright light therapy seems to stabilize and further enhance reduction of depressive symptoms during follow-up, whereas one night wake therapy does not have an additional long-lasting impact on depressive symptoms and sleep parameters.

    Psoriasis is a chronic inflammatory T cell-mediated skin disease, affecting about 2% of Hungarian population. Genetic predisposition as well as environmental triggering factors, and innate immune processes play a role in its etiology. Treatment of psoriasis during the initial stages and first years of disease tend to be conservative and frequently based on topical agents. The aim of this study was to investigate and to describe the efficacy and safety of Dr Michaels® (Soratinex®) skin-care products for the topical treatment of stable chronic plaque psoriasis in a Hungarian population. Two-hundred-and-eight-six (120 female/166 male) patients, aged 10-80 years old (mean age 43 years) with mild to moderate plaque psoriasis had participated in the study. The products, including cleansing gel containing a coal tar solution, herbal oils and emulsifiers, were used twice daily and in the same manner for all the skin lesions. The study period was eight weeks. Assessment, using the Psoriasis Activity Severity Index (PASI) scores and photographic analysis, was done 2 weeks before treatment, at time 0, and after 2, 4, 6 and 8 weeks. Patient’s improvement was determined by the percentage reduction of the PASI scores. Side effects and tolerability were also evaluated. After 8 weeks treatment course, 46 patients had a moderate improvement, with the regression of 25-50% of skin lesions; 77 patients showed a good improvement, with the resolution of 51-75% of lesions. Another 115 patients had an outstanding improvement, with the regression of 76-98.9% of lesions. Only 13 patients did not achieve an improvement of psoriasis. Fifteen patients experienced folliculitis, which resolved after cessation of treatment. Seven patients worsened and discontinued treatment. Thirteen patients dropped out because of non-compliance. Our investigation demonstrates that Dr Michaels® (Soratinex®) products, an Australian treatment, can be used successfully in the treatment of stable chronic plaque

    The study objective was to report treatment with an interleukin (IL)-1 receptor antagonist, anakinra, in patients with multiorgan Behcet's disease (BD). Comparison of clinical manifestations, previous treatments, markers of inflammation, concomitant medications, treatment regimen modifications, relapses, and adverse events before and during anakinra administration among patients with BD were evaluated. Nine BD patients (mean age 34.55 ± 16.30 years) refractory to tumor necrosis factor blockers and standardized therapies are reported in our survey. Their mean age at disease onset was 25 ± 13.88 years and their overall disease duration was 9.55 ± 5.33 years. All patients were positive for the HLA-B51 allele. Within 1 or 2 weeks following the initiation of anakinra, eight out of nine patients promptly responded, and most of them were maintained on 100 mg of daily anakinra with low doses of prednisone. However, most patients experienced a relapse in one or more clinical manifestations over time (mean time to relapse 29 ± 21.65 weeks), and only one patient remained completely under control on anakinra monotherapy. Despite a relapse in one or more disease manifestations, treatment was continued in most patients for a mean period of 13.75 ± 6.49 months. No serious adverse events occurred. Eight out of nine refractory BD patients showed a prompt improvement after starting anakinra, supporting the concept that IL-1 plays a pathological role in this disease. Nevertheless, after several months, most patients experienced a relapse. It remains unclear whether increasing the dose of anakinra would have prevented the reoccurrence of disease activity.

    Stimulated by the recent discovery of the 1 yr recurrence period nova M31N 2008-12a, we examined the shortest recurrence periods of hydrogen shell flashes on mass-accreting white dwarfs (WDs). We discuss the mechanism that yields a finite minimum recurrence period for a given WD mass. Calculating the unstable flashes for various WD masses and mass accretion rates, we identified a shortest recurrence period of about two months for a non-rotating 1.38 M {sub ☉} WD with a mass accretion rate of 3.6 × 10{sup –7} M {sub ☉} yr{sup –1}. A 1 yr recurrence period is realized for very massive (≳ 1.3 M {sub ☉}) WDs with very high accretion rates (≳ 1.5 × 10{sup –7} M {sub ☉} yr{sup –1}). We revised our stability limit of hydrogen shell burning, which will be useful for binary evolution calculations toward Type Ia supernovae.

    Humans occasionally become infected with acanthocephalans, particularly Moniliformis moniliformis. Although several anthelmintics have been used, no controlled studies have been conducted to assess the efficacy of common anthelmintics in the treatment of moniliformiasis. The effectiveness of pyrantel pamoate, ivermectin, praziquantel, niclosamide, thiabendazole, and mebendazole was evaluated in the treatment of moniliformiasis in laboratory-infected female Wistar rats. Pyrantel pamoate and ivermectin were wholly unsuccessful in the treatment of moniliformiasis. A single dose of thiabendazole lead to a 40% reduction and two doses lead to a 57% reduction of worm burden after 2 weeks. The most effective drug in the treatment of moniliformiasis in rats was mebendazole, for which two doses resulted in a 69% reduction in worm burden after 2 weeks; however, 50% of the rats receiving the treatment died within 2 weeks after first administration of the drug. Two surviving rats that had been treated with mebendazole exhibited evidence of hepatic dysfunction characterized by extremely elevated levels of alkaline phosphatase in conjuction with depressed serum albumin levels. It is hypothesized that Mo. moniliformis may metabolize the drug and release a metabolite that is highly toxic to the host. On the basis of these data, thiabendazole is recommended as the drug of choice for the treatment of human acanthocephaliasis until more extensive testing can be conducted. PMID:21254932

    The reproductive performance of beef cows and the weight gain of their calves was evaluated after oral administration of clorsulon or clorsulon in combination with the subcutaneous administration of ivermectin. One hundred and fifty pregnant cows harboring infections of Fasciola hepatica were assigned to one of three treatment groups: Group 1 comprising 50 unmedicated controls; Group 2, 50 cows treated with clorsulon orally at 7 mg kg-1; Group 3, 50 cows treated with clorsulon orally at 7 mg kg-1 and ivermectin subcutaneously at 200 micrograms kg-1. Weights and body condition scores of the cows were measured and fecal and blood samples were taken at trial initiation and days 158 and 270. Pregnancy status was also determined at day 270. Weights and body condition scores were measured for the calves at days 158 and 270. Adjusted 205 day weaning weight of the calves was calculated and analyzed for differences between treatment groups. Four sets of tracer calves were used periodically throughout the trial to monitor the helminth challenge to the herd. Both gastro-intestinal nematodes and liver flukes were transmitted to the tracer calves during the entire trial. Even in the face of continual helminth challenge, beef cows treated with combined clorsulon/ivermectin conceived approximately 2 weeks earlier than their untreated counterparts and their calves had better body condition scores and weights than untreated calves.

    The current study investigated the effectiveness of a home practice program based on the iPad (Apple Inc., Cupertino, CA), implemented after 2 weeks of intensive language therapy, for maintaining and augmenting treatment gains in people with chronic poststroke aphasia. Five of eight original participants completed the 6-month home practice program in which they autonomously practiced retrieving words for objects and actions. Half of these words had been trained and half were untrained during therapy. Practice included tasks such as naming to confrontation, repeating from a video model, and picture/word matching presented on an iPad. All participants maintained advances made on words trained during the intensive treatment and additionally were able to learn new words by practicing daily over a 6-month period. The iPad and other tablet devices have great potential for personalized home practice to maintain and augment traditional aphasia rehabilitation. It appears that motivation to use the technology and adequate training are more important factors than age, aphasia type or severity, or prior experience with computers. PMID:24449465

    The interaction of electromagnetic waves of wavelength lambda with periodic structures of spatial period lambda are studied. The emphasis of the work is on Bragg interactions where lambda approximately equal to 2 lambda/N and the Bragg order N takes on the values 1, 2,.... An extended coupled waves (ECW) theory is developed for the case N greater or equal to 2 and the results of the theory are found to compare favorably with the exact results of Floquet theory. Numerous numerical results are displayed as Brillouin diagrams for the first few Bragg orders. Moreover, explicit expressions for coupling coefficients, bandgap shifts and bandgap widths are derived for singly periodic media. Particular note is taken of phase speeding effects.

    The overall moduli of a composite with an isotropic elastic matrix containing periodically distributed (anisotropic) inclusions or voids, can be expressed in terms of several infinite series which only depend on the geometry of the inclusions or voids, and hence can be computed once and for all for given geometries. For solids with periodic structures these infinite series play exactly the same role as does Eshelby's tensor for a single inclusion or void in an unbounded elastic medium. For spherical and circular-cylindrical geometries, the required infinite series are calculated and the results are tabulated. These are then used to estimate the overall elastic moduli when either the overall strains or the overall stresses are prescribed, obtaining the same results. These results are compared with other estimates and with experimental data. It is found that the model of composites with periodic structure yields estimates in excellent agreement with the experimental observations.

    The periodicity of extinction events is examined in detail. In particular, the temporal distribution of specific, identifiable extinction events is analyzed. The nature and limitations of the data base on the global fossil record is discussed in order to establish limits of resolution in statistical analyses. Peaks in extinction intensity which appear to differ significantly from background levels are considered, and new analyses of the temporal distribution of these peaks are presented. Finally, some possible causes of periodicity and of interdependence among extinction events over the last quarter billion years of earth history are examined.

    A method is proposed for the automatic detection of serial periodicities in a linear sequence. Its application to DNA subtelomeric sequences from two lower eukaryotes, P.falciparum and S.cerevisiae, reveals ordered patterns organised in hierarchical periodicities, not easily recognizable by other methods. The possible implications concerning the evolution of tandemly repetitive arrays are discussed in light of a model which involves, as successive steps, random repeat modification, the fusion of differently modified repeat versions into longer units, and the amplification of (and/or homogenization to) the more recent repeat units.

    Background: Hydroxymethylglutaryl-coenzyme A reductase inhibitors (statins) are antihyperlipidemic drugs with an established efficacy in stabilizing atherosclerotic plaques and preventing atherogenesis and reducing cardiovascular events. The purpose of this study was to determine the effect of simvastatin on serum Vitamin D status in dyslipidemic patients as Vitamin D status has an impact on monocyte/macrophage function and may also contribute to cardiovascular risk. Methods: Selected individuals (n = 102) were treated with simvastatin (40 mg/day), or matching placebo in a randomized, double-blind, placebo-controlled, crossover trial. Each treatment period (with simvastatin or placebo) lasted for 30 days and was separated by a 2-week washout phase. Serum Vitamin D concentration was assessed pre- and post-treatment. Results: Seventy-seven completed the trial, noncompliance with the study protocol and drug intolerance or relocation were the causes for drop-out. No significant carry-over effect was observed for the assessed parameters. There was a reduction in the serum levels of low-density lipoprotein cholesterol (P < 0.001), total cholesterol (P < 0.001), and triglycerides (P < 0.05). Nevertheless, simvastatin therapy did not significantly affect serum level of high-density lipoprotein cholesterol and Vitamin D level (P > 0.05). Conclusions: Short-term treatment with simvastatin (40 mg/day) does not have a significant affect on serum levels of Vitamin D. PMID:27330686

    An implantable, anti-microbial delivery device for the treatment of periodontal disease has been developed. In this polymer-based delivery system, the encapsulation efficiency, release characteristics, and bioactivity of anti-microbial agent were controlled by the complexation of the drug with cyclodextrins of differing lipophilicity. Microparticles of poly(dl-lactic-co-glycolic acid) (PLGA) containing chlorhexidine (Chx) free base, chlorhexidine digluconate (Chx-Dg) and their association or inclusion complex with methylated-beta-cyclodextrin (MBCD) and hydroxypropyl-beta-cyclodextrin (HPBCD) were prepared by single emulsion, solvent evaporation technique. It was observed that encapsulation efficiency and release of the chlorhexidine derivatives from the microparticles was a function of the lipophilicity of the cyclodextrin. Complexation of the poorly water soluble Chx with the more hydrophilic HPBCD resulted in 62% higher encapsulation efficiency and longer duration of sustained release over a 2-week period than complexation with the more lipophilic MBCD. In contrast, the complexation of the more water-soluble derivative of chlorhexidine, Chx-Dg, with the more lipophilic MBCD improved encapsulation efficiency by 12% and prolonged its release in comparison to both the free Chx-Dg and its complex with HPBCD. Furthermore, it was observed that the initial burst effect could be diminished by complexation with CD. Preliminary studies have shown that the chlorhexidine released from PLGA chips is biologically active against bacterial population that is relevant in periodontitis (P. gingivalis and B. forsythus) and a healthy inhibition zone is maintained in agar plate assay over a period of at least a 1-week. The PLGA/CD delivery system described in this paper may prove useful for the localized delivery of chlorhexidine salts and other anti-microbial agents in the treatment of periodontal disease where prolonged-controlled delivery is desired.

  1. Periodicities of polar cap patches

    NASA Astrophysics Data System (ADS)

    2013-01-01

    A highly sensitive all-sky electron multiplier charge-coupled device airglow imager has been operative in Longyearbyen, Norway since October 2011. The imager captures 630.0 nm all-sky images with an exposure time of 4 s, which is about 10 times shorter than that achieved by conventional cooled CCD imagers. This allows us to visualize the structure of polar cap patches without blurring effects and better estimate their periodicities. We present, as one of the first results from the imager, an event of successive appearance of patches on the night of 21 December 2011. A time series of the optical intensity at zenith showed modulations having two distinguished periods, one at 40 min and the other at 5-12 min. One possible explanation is that such a coexistence of two different periodicities is a manifestation of simultaneous occurrence of patch generation processes on the 40 min periodicity was created by large-scale reconfiguration of the dayside convection pattern while the 5-12 min modulations were closely associated with mechanisms driven by pulsed reconnection on the dayside magnetopause. Such a combined effect of multiple patch generation processes may play a role in structuring patches; thus, it would be of particular importance for evaluating the space weather effects in the trans-ionospheric communications environment in the polar cap.

  4. Stability of underwater periodic locomotion

    NASA Astrophysics Data System (ADS)

    Jing, Fangxu; Kanso, Eva

    2013-07-01

    Most aquatic vertebrates swim by lateral flapping of their bodies and caudal fins. While much effort has been devoted to understanding the flapping kinematics and its influence on the swimming efficiency, little is known about the stability (or lack of) of periodic swimming. It is believed that stability limits maneuverability and body designs/flapping motions that are adapted for stable swimming are not suitable for high maneuverability and vice versa. In this paper, we consider a simplified model of a planar elliptic body undergoing prescribed periodic heaving and pitching in potential flow. We show that periodic locomotion can be achieved due to the resulting hydrodynamic forces, and its value depends on several parameters including the aspect ratio of the body, the amplitudes and phases of the prescribed flapping.We obtain closedform solutions for the locomotion and efficiency for small flapping amplitudes, and numerical results for finite flapping amplitudes. This efficiency analysis results in optimal parameter values that are in agreement with values reported for some carangiform fish. We then study the stability of the (finite amplitude flapping) periodic locomotion using Floquet theory. We find that stability depends nonlinearly on all parameters. Interesting trends of switching between stable and unstable motions emerge and evolve as we continuously vary the parameter values. This suggests that, for live organisms that control their flapping motion, maneuverability and stability need not be thought of as disjoint properties, rather the organism may manipulate its motion in favor of one or the other depending on the task at hand.

    Better quantification of nitrogen mineralization and nitrification after fumigation would indicate if any adjustment is needed in fertilizer application. The effects of chloropicrin (Pic), 1,3-dichloropropene (1,3-D), dimethyl disulfide (DMDS) and metham sodium (MS) fumigation on soil nitrogen dynamics were evaluated in lab incubation and field studies. Although some differences were observed in NH(4)(+)-N and NO(3)(-)-N concentrations in lab incubation and field experiments, both studies led to the same conclusions: (1) Soil fumigation was shown to increase soil mineral nitrogen only during the first 2 weeks after fumigation (WAF). In particular, Pic significantly increased soil mineral nitrogen in both studies at 1 WAF. However, for all fumigant treatments the observed effect was temporary; the soil mineral content of treated samples recovered to the general level observed in the untreated control. (2) All the fumigation treatments depressed nitrification temporarily, although the treatments exhibited significant differences in the duration of nitrification inhibition. In both studies, for a limited period of time, Pic showed a stronger inhibitory effect on nitrification compared to other fumigant treatments. An S-shaped function was fitted to the concentrations of NO(3)(-)-N in lab incubation samples. The times of maximum nitrification (t(max)) in DMDS and MS treatments were 0.97 week and 1.03 week, which is similar to the untreated control (t(max)=1.02 week). While Pic has the longest effect on nitrifying bacteria, nitrification appears to restart at a later time (t(max)=14.37 week). PMID:23062947

  11. Lasting treatment effects in a postmarketing surveillance study of prolonged-release melatonin.

    2015-01-01

    Surveillance studies are useful to evaluate how a new medicinal product performs in everyday treatment and how the patient who takes it feels and functions, thereby determining the benefit/risk ratio of the drug under real-life conditions. Prolonged-release melatonin (PRM; Circadin) was approved in Europe for the management of primary insomnia patients age 55 years or older suffering from poor quality of sleep. With traditional hypnotics (e.g. benzodiazepine-receptor agonists), there are concerns about rebound insomnia and/or withdrawal symptoms. We report data from a postmarketing surveillance study in Germany on the effects of 3 weeks of treatment with PRM on sleep in patients with insomnia during treatment and at early (1-2 days) and late (around 2 weeks) withdrawal. In total, 653 patients (597 evaluable) were recruited at 204 sites (mean age 62.7 years, 68% previously treated with hypnotics, 65% women). With PRM treatment, the mean sleep quality (on a scale of 1-5 on which 1 is very good and 5 is very bad) improved from 4.2 to 2.6 and morning alertness improved from 4.0 to 2.5. The improvements persisted over the post-treatment observation period. Rebound insomnia, defined as a one-point deterioration in sleep quality below baseline values, was found in 3.2% (early withdrawal) and 2.0% (late withdrawal). Most of the patients (77%) who used traditional hypnotics before PRM treatment had stopped using them and only 5.6% of naive patients started such drugs after PRM discontinuation. PRM was well tolerated during treatment and the most frequently reported adverse events were nausea (10 patients, 1.5%), dizziness, restlessness and headache (five patients each, <1%). There were no serious adverse events and no adverse events were reported after discontinuation. The persisting treatment effect and very low rebound rate suggest a beneficial role of sleep-wake cycle stabilization with PRM in the treatment of insomnia. PMID:25054634

  12. Quantum gates by periodic driving

    Topological quantum computation has been extensively studied in the past decades due to its robustness against decoherence. One way to realize the topological quantum computation is by adiabatic evolutions—it requires relatively long time to complete a gate, so the speed of quantum computation slows down. In this work, we present a method to realize single qubit quantum gates by periodic driving. Compared to adiabatic evolution, the single qubit gates can be realized at a fixed time much shorter than that by adiabatic evolution. The driving fields can be sinusoidal or square-well field. With the sinusoidal driving field, we derive an expression for the total operation time in the high-frequency limit, and an exact analytical expression for the evolution operator without any approximations is given for the square well driving. This study suggests that the period driving could provide us with a new direction in regulations of the operation time in topological quantum computation. PMID:26911900

    The optimal Bayes detector for a general periodic waveform having uniform delay and additive white Gaussian noise is examined. It is shown that the detector is much more complex than that for the well known cases of pure sine waves (i.e. classical noncoherent detection) and narrowband signals. An interpretation of the optimal processing is presented, and several implementations are discussed. The results have application to the noncoherent detection of optical square waves.

    2016-01-01

    Ultrasound imaging is an adjunct to traditional speech therapy that has shown to be beneficial in the remediation of speech sound errors. Ultrasound biofeedback can be utilized during therapy to provide clients with additional knowledge about their tongue shapes when attempting to produce sounds that are erroneous. The additional feedback may assist children with childhood apraxia of speech (CAS) in stabilizing motor patterns, thereby facilitating more consistent and accurate productions of sounds and syllables. However, due to its specialized nature, ultrasound visual feedback is a technology that is not widely available to clients. Short-term intensive treatment programs are one option that can be utilized to expand access to ultrasound biofeedback. Schema-based motor learning theory suggests that short-term intensive treatment programs (massed practice) may assist children in acquiring more accurate motor patterns. In this case series, three participants ages 10-14 years diagnosed with CAS attended 16 h of speech therapy over a 2-week period to address residual speech sound errors. Two participants had distortions on rhotic sounds, while the third participant demonstrated lateralization of sibilant sounds. During therapy, cues were provided to assist participants in obtaining a tongue shape that facilitated a correct production of the erred sound. Additional practice without ultrasound was also included. Results suggested that all participants showed signs of acquisition of sounds in error. Generalization and retention results were mixed. One participant showed generalization and retention of sounds that were treated; one showed generalization but limited retention; and the third showed no evidence of generalization or retention. Individual characteristics that may facilitate generalization are discussed.

    Objective To compare bupropion to placebo for reducing methamphetamine (MA) use, increasing retention, and reducing the severity of depressive symptoms and MA cravings. A secondary objective compared bupropion to placebo for reducing cigarette smoking among MA dependent participants. Methods Following a 2-week, non-medication baseline screening period, 73 treatment-seeking MA dependent participants were randomly assigned to bupropion sustained release (150 mg twice daily; N=36) or placebo (twice daily; N=37) for 12-weeks under double blind conditions. Participants attended clinic thrice weekly to provide urine samples analyzed for MA-metabolite, to complete research measures and assessments, and to receive contingency management and weekly cognitive behavioral therapy sessions. Results There were no statistically significant effects for bupropion relative to placebo on MA use verified by urine drug screens, for reducing the severity of depressive symptoms or MA cravings, or on study retention. In a post hoc analysis, there was a statistically significant effect of bupropion treatment on MA use among participants with lighter (0–2 MA-positive urines), but not heavier (3–6 MA-positive urines) MA use during baseline (OR=2.81, 95% CI=1.61–4.93, p<0.001 for MA-free week with bupropion among light users). Bupropion treatment was also associated with significantly reduced cigarette smoking, by almost 5 cigarettes per day (p=0.0002). Conclusion Bupropion was no more effective than placebo in reducing MA use in planned analyses, though bupropion did reduce cigarette smoking. Post hoc findings of an effect for bupropion among baseline light, but not heavy, MA users suggests further evaluation of bupropion for light MA users is warranted. PMID:18468815

    Highlights: {yields} Anti-diabetic new drug, DPP-4 inhibitor, can affect the insulin exocytosis. {yields} DPP-4 inhibitor treatment altered syntaxin 1 expression. {yields} Treatment of db/db mice with DPP-4 inhibitor increased insulin release. -- Abstract: Incretin promotes insulin secretion acutely. Recently, orally-administered DPP-4 inhibitors represent a new class of anti-hyperglycemic agents. Indeed, inhibitors of dipeptidyl peptidase-IV (DPP-4), sitagliptin, has just begun to be widely used as therapeutics for type 2 diabetes. However, the effects of sitagliptin-treatment on insulin exocytosis from single {beta}-cells are yet unknown. We therefore investigated how sitagliptin-treatment in db/db mice affects insulin exocytosis by treating db/db mice with des-F-sitagliptin for 2 weeks. Perfusion studies showed that 2 weeks-sitagliptin treatment potentiated insulin secretion. We then analyzed insulin granule motion and SNARE protein, syntaxin 1, by TIRF imaging system. TIRF imaging of insulin exocytosis showed the increased number of docked insulin granules and increased fusion events from them during first-phase release. In accord with insulin exocytosis data, des-F-sitagliptin-treatment increased the number of syntaxin 1 clusters on the plasma membrane. Thus, our data demonstrated that 2-weeks des-F-sitagliptin-treatment increased the fusion events of insulin granules, probably via increased number of docked insulin granules and that of syntaxin 1 clusters.

    We report 37 patients ranging in age from 1 month to 14 years treated for intestinal malrotation during a five year period. The main presenting features consisted of intermittent attacks of vomiting (15 patients), failure to thrive (seven), and recurrent colicky abdominal pain (seven). The diagnosis was confirmed by gastrointestinal contrast studies in all but three patients. A standard Ladd's procedure comprised the definitive surgical treatment. We emphasise the poor nutritional state at the time of operation (49% of the cases were on or below the third centile). In contrast with neonatal presentation, volvulus of the midgut occurred in only five patients (14%) compared with 68% in neonates with malrotation. There were two deaths in the series. Ninety four per cent of the remaining patients responded favourably to the operative procedure. Malrotation should be considered in the differential diagnosis of a wide variety of symptoms and should be treated promptly once the diagnosis has been confirmed. PMID:3740908

    PubMed Central

    1971-01-01

    Evidence has accumulated of rhythmic numerical oscillation of each of the blood cells either independently or in combinations. The cyclic changes originate in the marrow of some normal persons and animals without causing illness, and can be induced experimentally. In more than 100 reported instances, periodic oscillations of various cells were accompanied by respective episodes of the disorders named in the title. The disorders may be transitory but usually recur throughout life and occasionally are fatal. All resist therapy. Features in common suggest an interrelationship of the haemal disorders and other disparate heritable periodic diseases. Theoretically, the rhythms are regulated by ubiquitous, inherent, intracellular bioclocks controlled hypothalamically or neurohumorally in relation to a feedback mechanism. Reactions to long cycles are of greater clinical importance than disturbances arising from the circadian rhythm. PMID:4397784

    Takotsubo cardiomyopathy simulates acute myocardial infarction, and it is characterised by reversible left ventricular failure. A case of Takotsubo cardiomyopathy diagnosed after emergency angiography performed in a patient with evidence of acute myocardial infarction in the postoperative period will be described in this report. Transurethral resection of a bladder tumour (TUR-BT) was performed in a 92-year-old male patient by the urology clinic. The patient was transferred to the post-anaesthesia care unit after the operation. An echocardiography was performed because of the sudden onset of dyspnoea, tachycardia (140-150 beats per minute, rhythm-atrial fibrillation) and ST-segment elevation on electrocardiography (ECG) at the first postoperative hour, and midapical dyskinesia was detected at the patient. An immediate angiography was performed due to suspicion of acute coronary syndrome. Patent coronary arteries and temporary aneurysmatic dilatation of the apex of the heart were revealed by angiography. As a result of these findings, the patient was diagnosed with Takotsubo cardiomyopathy by the cardiology service. The patient was discharged uneventfully following 10 days in the intensive care unit. Aneurysm of the apex of the left ventricle and normal anatomy of the coronary arteries in the angiography have diagnostic value for Takotsubo cardiomyopathy. Diuretics (furosemide) and beta-blockers (metoprolol) are commonly used for the treatment of Takotsubo cardiomyopathy. Even though Takotsubo cardiomyopathy is a rare and benign disease, it should be kept in mind in patients suspected for acute myocardial infarction in the postoperative period. PMID:27366464

    Background About 468 million non-pregnant women are estimated to suffer from iron-deficiency anemia (IDA) worldwide. The highest prevalence of IDA occurs in the Taiwanese population. Objective To evaluate the effectiveness of Herbiron to increase iron absorption in women with IDA. Design Phase III double-blind, randomized, active-controlled, and parallel comparative study enrolled 124 patients with IDA and consisted of a 2-week run-in period, randomization, 12 weeks of supplementation, and 4 weeks of follow-up. The treatment group received Herbiron drink 50 mL p.o., b.i.d., before meals (daily iron intake: 21 mg/day) plus placebo tablets. The control group received a ferrous sulfate tablet, t.i.d., plus placebo 50-mL drink before meals (daily iron intake: 195 mg/day). Results Both treatments significantly improved hemoglobin and all secondary efficacy endpoints. Most IDA patients treated with Herbiron or ferrous sulfate finished the study in the normal range. Ferrous sulfate treatment induced a rapid rate of hemoglobin synthesis, which plateaued by week 8, whereas Herbiron treatment increased the rate of hemoglobin synthesis more slowly, likely due to its nine-fold lower iron content. Gastrointestinal adverse events (diarrhea, abdominal pain, dyspepsia, and nausea) but not infectious adverse events were significantly more common in the ferrous sulfate group (n=11, 18.3%) than those in the Herbiron group (n=1, 1.6%) (p=0.004). Conclusion Twelve weeks of Herbiron treatment delivering 21mg of iron or ferrous sulfate treatment delivering 195 mg of iron induced normal hemoglobin levels in 62 or 91% of non-pregnant women with IDA in Taiwan, respectively, suggesting dose-dependent and bioavailability effects.

    Consideration is given to the rotation period of comet Donati (1858 VI) whose haloes were approximate parabolic envelopes having foci near the apparent nucleus and vertices toward the sun forward from the tail axis. The regularity and sharpness of the halves suggest that they represent the repetitive ejection of material from an active area which is exposed to solar radiation as the cometary nucleus rotates. Bobrovnikov's results (1954) are used to evaluate the linear expansion velocity of such haloes. This calculation is applied to the comet and a linear correction is used to assess the results.

  10. Long-Period Solar Variability

    Terrestrial climate records and historical observations of the Sun suggest that the Sun undergoes aperiodic oscillations in radiative output and size over time periods of centuries and millenia. Such behavior can be explained by the solar convective zone acting as a nonlinear oscillator, forced at the sunspot-cycle frequency by variations in heliomagnetic field strength. A forced variant of the Lorenz equations can generate a time series with the same characteristics as the solar and climate records. The timescales and magnitudes of oscillations that could be caused by this mechanism are consistent with what is known about the Sun and terrestrial climate.

    We propose a simple approach to determine all possible wheels that can roll smoothly without slipping on a periodic roadbed, while maintaining the center of mass at a fixed height. We also address the inverse problem that of obtaining the roadbed profile compatible with a specific wheel and all other related "quantized wheels." The role of symmetry is highlighted, which might preclude the center of mass from remaining at a fixed height. A straightforward consequence of such geometric quantization is that the gravitational potential energy and the moment of inertia are discrete, suggesting a parallelism between macroscopic wheels and nano-systems, such as carbon nanotubes.

    A periodic permanent magnet (PPM) klystron has beam transport structures and RF cavity structures, each of which has permanent magnets placed substantially equidistant from a beam tunnel formed about the central axis, and which are also outside the extent of a cooling chamber. The RF cavity sections also have permanent magnets which are placed substantially equidistant from the beam tunnel, but which include an RF cavity coupling to the beam tunnel for enhancement of RF carried by an electron beam in the beam tunnel.

    1994-08-01

    A model explaining the presence of a periodic train of microwave absorption lines in the magnetic modulated microwave absorption (MMMA) spectra of high- and low-temperature superconductors is proposed. The model assumes the occurrence of regular superconducting current loops, closed by Josephson junctions, in these materials. The system of such loops is considered within the basic model of the rf superconducting quantum interference device taking into account the effect of thermal fluctuations. The magnetic-field and temperature dependencies of the MMMA obtained on the basis of the proposed model are in qualitative agreement with experimental data.

    Scabies is found worldwide among people of all groups and ages. It is curable with scabicide medications. This study aimed to compare the efficacy and safety of oral ivermectin vs malathion 0.5% lotion for the treatment of scabies. In total, 148 patients with scabies were enrolled and randomized into two groups: the first group received a single dose of oral ivermectin 200 sg/kg body weight, and the second was treated with two applications of topical lindane lotion 1%, with a 1-week interval between applications. Treatment was evaluated at intervals of 2 and 4 weeks, and if there was treatment failure at the 2-week follow-up, treatment was repeated. A single dose of ivermectin provided a cure rate of 60.8% at the 2-week follow-up, which increased to 89.1% at the 4-week follow-up after repeating the treatment. Treatment with two applications oflindane lotion 1%, with a 1-week interval between them, was effective in 47.2% of patients at the 2-week follow-up, which increased to 72.9% at the 4-week follow-up after this treatment was repeated. A single dose of ivermectin was as effective as two applications of lindane lotion 1% at the 2-week follow-up. After repeat treatment, ivermectin was superior to lindane lotion 1% at the 4-week follow-up. The delay in clinical response with ivermectin suggests that it may not be effective against the parasite at all stages in the life cycle. PMID:25632646

    Background Fecal calprotectin has been proposed as a non-invasive marker of intestinal inflammation in inflammatory bowel disease in adults and children. Fecal calprotectin levels have been reported to be much higher in both healthy full-term and preterm infants than in children and adults. Objective To determine the time course of fecal calprotectin (f-calprotectin) excretion in preterm infants from birth until hospital discharge and to identify factors influencing f-calprotectin levels in the first weeks of life, including bacterial establishment in the gut. Methodology F-calprotectin was determined using an ELISA assay in 147 samples obtained prospectively from 47 preterm infants (gestational age, and birth-weight interquartiles 27–29 weeks, and 880–1320 g, respectively) at birth, and at 2-week intervals until hospital discharge. Principal Findings Although median f-calprotectin excretion was 138 µg/g, a wide range of inter- and intra-individual variation in f-calprotectin values (from day 3 to day 78) was observed (86% and 67%, respectively). In multivariate regression analysis, f-calprotectin correlated negatively with ante and per natal antibiotic treatment (p = 0.001), and correlated positively with the volume of enteral feeding (mL/kg/d) (p = 0.009), the need to interrupt enteral feeding (p = 0.001), and prominent gastrointestinal colonization by Clostridium sp (p = 0.019) and Staphylococcus sp (p = 0.047). Conclusion During the first weeks of life, the high f-calprotectin values observed in preterm infants could be linked to the gut bacterial establishment. PMID:20552029

  4. Periodic bedrock ridges on Mars

    Evidence for sediment transport and erosion by wind is widespread over the surface of Mars today and was likely a major geomorphic process for much of its geological past. Although Martian surface features resembling aeolian dunes and ripples have been recognized since the Mariner and Viking missions, such features have been interpreted previously as active, indurated, or exhumed sedimentary forms. Here we report evidence based on High Resolution Imaging Science Experiment images that show some megaripple forms are eroded into cohesive substrate rather than being composed of loose granular material or fossilized dunes. Exposure of stratigraphic continuity within layered, cohesive material extending crest to trough through features with mean wavelengths of 18 to 51 m demonstrates the primarily erosional formation of what we term periodic bedrock ridges (PBRs). Hence some surfaces on Mars previously considered to be covered by wind-deposited material are actually wind-carved exposures that offer windows into Martian history. PBRs lack the distinctive streamlining associated with wind-parallel yardangs and comparison of PBR orientation to yardangs, megayardangs, and active sedimentary dunes in the same vicinity confirm that these PBRs formed transverse to prevailing winds. Observed wavelengths of PBRs are comparable to those predicted by a simple model for erosional wavelengths of periodic transverse bed forms owing to the spacing of flow separations within the flow. Recognition of these transverse aeolian erosional forms brings up the question of how widespread Martian PBRs are and how many have been misinterpreted as active or indurated (fossilized) sedimentary dunes.

    This paper presents the online estimation of temporal frequency to simultaneously detect and identify the quasiperiodic motion of an object. We introduce color to increase discriminative power of a reoccurring object and to provide robustness to appearance changes due to illumination changes. Spatial contextual information is incorporated by considering the object motion at different scales. We combined spatiospectral Gaussian filters and a temporal reparameterized Gabor filter to construct the online temporal frequency filter. We demonstrate the online filter to respond faster and decay faster than offline Gabor filters. Further, we show the online filter to be more selective to the tuned frequency than Gabor filters. We contribute to temporal frequency analysis in that we both identify ("what") and detect ("when") the frequency. In color video, we demonstrate the filter to detect and identify the periodicity of natural motion. The velocity of moving gratings is determined in a real world example. We consider periodic and quasiperiodic motion of both stationary and nonstationary objects. PMID:16764282

    The discovery of a new class of Navier-Stokes solutions representing steady periodic stretched vortices offers a useful test-bed for examining interactions between flames and complex flow-fields. After briefly describing these vortex solutions and their wide-ranging parameterization in terms of wavelength and amplitude, this article examines their effect on flames of constant normal propagation speed as observed through numerical solutions of an eikonal equation. Over certain ranges of vortex amplitude and flame-speed, a corridor of enhanced flame passage is seen to be created as a leading flame-tip managers to leap-frog between successive vortices. However, for large enough amplitudes of vorticity or small enough flame-speeds, the flame fails to be able to benefit from the advection due to the vortices. It is shown that the leading tips of such flames are effectively trapped by the stretched vortices.

    The D-dimensional Coulomb system serves as a starting point for generating generalized atomic shells. These shells are ordered according to a generalized Madelung rule in D dimensions. This rule together with an Aujbau Prinzip is applied to produce a D-dimensional periodic table. A model is developed to rationalize the ordering of the shells predicted by the generalized Madelung rule. This model is based on the introduction of a Hamiltonian, invariant under the q-deformed algebra U{sub q}(so(D)), that breaks down the SO(D + 1) dynamical symmetry of the hydrogen atom in D dimensions. The D = 2 case (Flatland) is investigated in some detail. It is shown that the neutral atoms and the (moderately) positive ions correspond to the values q = 0.8 and q = 1, respectively, of the deformation parameter q. 55 refs.

    The high energy demands of dairy cows during the transition period from late gestation into early lactation can place them at an increased risk for the development of metabolic and infectious diseases. Modification of the dry period diet has been investigated as a preventive means to minimize the detrimental aspects of metabolic shifts during the transition period. Studies investigating the impact of dry period diet on lipid parameters during the transition period have largely focused on markers of lipolysis and ketogenesis. Total cholesterol declines during the periparturient period and increases in early lactation. The impact total energy in the dry period diet has on the ability of the cow to maintain total serum cholesterol, as well as its natural high-density lipoprotein-rich status, during this metabolically challenging window is not clear. The impact of lipoproteins on inflammation and immune function may have a clinical impact on the cow's ability to ward off production-related diseases. In this study, we hypothesized that the provision of adequate, but not excessive, total metabolizable energy, would better allow the cow to maintain total cholesterol and a higher relative proportion of HDL throughout the transition period. Cows were allocated to one of three dry period dietary treatment groups following a randomized block design. Total serum triglycerides, cholesterol and lipoprotein fractions were measured on a weekly basis from approximately 7 weeks pre-calving to 6 weeks post-calving. The cows on the high energy diet maintained total serum cholesterol as compared to the cows provided a lower energy diet, but there was no significant increase in the LDL fraction of lipoproteins between diet treatment groups.

    Objective We examined the long-term outcome of participants in the Treatment of SSRI-Resistant Depression in Adolescents (TORDIA) study, a randomized trial of 334 adolescents (aged 12-18 years) with DSM-IV-defined major depression disorder initially resistant to selective serotonin reuptake inhibitor (SSRI) treatment who were and subsequently treated for 12 weeks with another SSRI, venlafaxine, another SSRI + cognitive behavioral therapy (CBT), or venlafaxine + CBT. Responders then continued with the same treatment through week 24, while non-responders were given open treatment. Method For the current study, patients were reassessed 48 (N=116) and 72 (N=130) weeks from intake. Data were gathered from February 2011 to February 2007. Standardized diagnostic interviews and measures of depression, suicidal ideation, related psychopathology and level of functioning were periodically administered. Remission was defined as ≥ 3 weeks with ≤ 1 clinically significant symptom and no associated functional impairment (score of 1 on the adolescent version of the Longitudinal Interval Follow-Up Evaluation [A-LIFE], and relapse as ≥ 2 weeks with probable or definite depressive disorder (score of 3 or 4 on the A-LIFE). Mixed effects regression models were applied to estimate remission, relapse, and functional recovery. Results By 72 weeks, an estimated 61.1% of the randomized youths had reached remission. Randomly assigned treatment (first 12 weeks) did not influence remission rate or time to remission, but the group assigned to SSRI's had a more rapid decline in self-reported depressive symptoms and suicidal ideation than those assigned to venlafaxine (p<.05). Participants with more severe depression, greater dysfunction, and alcohol/drug use at baseline were less likely to remit. The depressive symptom trajectory of the remitters diverged from that of non-remitters by the first 6 weeks of treatment (p<.001). Of the 130 participants in remission at week 24, 25.4% relapsed in

    New drugs that can shorten tuberculosis (TB) treatment and target drug resistant strains are urgently needed. A test which could predict patients at risk of a delayed response to treatment would facilitate clinical trials of new anti-tuberculosis drugs. A widely-used test for the assessment of response to treatment is sputum smear examination. Patients who are smear positive after 2 and 3 months of treatment are said to have delayed and significantly delayed treatment responses respectively. Time to positivity (TTP) values of Bactec cultures, from the first 2 weeks of treatment were used to predict delayed and significantly delayed treatment responses in patients with first time pulmonary tuberculosis. Changes in TTP values early in treatment were transformed to a response ratio (r). Values of r that were less than a threshold value (r(c)) indicated patients who were at risk of having delayed or significantly delayed response to treatment. Accuracy of prediction was sensitive to the timing of sputum sampling and adherence to therapy in the first 2 weeks. Based on TTP data from the first 2 weeks of treatment, significantly delayed treatment response could be predicted with a sensitivity of 75% and a specificity of 62% while the positive (PPV) and negative predictive values (NPV) were 14% and 97% respectively. While the high NPV indicates that a large proportion of patients with a satisfactory response to treatment can be reliably identified, the low PPV value underlines the need to use TTP in conjunction with other markers of disease activity to predict unfavourable treatment response in tuberculosis treatment.

    Our understanding of postpartum anxiety (PPA) in fathers is limited, despite the negative consequences of anxiety on the father and child. Offspring contact reduces PPA in mothers; however, parallel investigations in fathers has gone unaddressed. Adult neurogenesis in the dentate gyrus (DG) contributes to anxiety regulation and is altered during the postpartum period, yet the effects of fatherhood on the production, or survival, of newborn cells in the DG, and the role of adult neurogenesis in PPA regulation, have not been examined. Using the biparental California mouse (Peromyscus californicus), we examined the relationships among postnatal day, anxiety-like behavior and adult neurogenesis in fathers. We hypothesized that attenuated anxiety-like behavior and enhanced adult neurogenesis would be observed when father-offspring contact was increased. We observed a reduction in anxiety-like behavior on the elevated plus-maze, but only at PND 16, a time of peak pup retrieval. Fatherhood reduced 1-week survival of newborn cells; however, surviving cells were maintained until 2 weeks postpartum. In contrast, non-fathers experienced a significant reduction in the survival of newborn cells between 1 and 2 weeks postpartum. Fatherhood also increased the numbers of newborn cells that expressed a neuronal phenotype. Collectively, these findings suggest that offspring interaction contributes to reductions in anxiety-like behavior and the maintenance of newborn neurons in the DG of fathers. These data contribute to our knowledge of the postpartum affective state in fathers, findings that may contribute to improved health of both the father and offspring. PMID:26750200

    Background: Stress, anxiety, and postpartum depression are the most common problems among women in their childbearing age. Research has shown that aromatherapy administered during labor reduces anxiety in mothers. With regard to the specific biological conditions in postpartum period and the subsequent drop in hormone levels, this study investigated the effect of lavender on prevention of stress, anxiety, and postpartum depression in women. Materials and Methods: In a clinical trial, 140 women admitted to the obstetric and gynecological unit were randomly divided into aromatherapy and non-aromatherapy groups immediately after delivery. Intervention with aromatherapy consisted of inhaling three drops of lavender essential oil every 8 h with for 4 weeks. The control group received routine care after discharge and was followed up by telephone only. After 2 weeks, 1 and 3 months of delivery, women were assessed by the 21-item Depression, Anxiety, and Stress Scale and the Edinburgh stress, anxiety, and depression scale in the two groups. Data analysis was performed by Mann-Whitney, analysis of variance (ANOVA), and post hoc tests. Level of significance was set as 0.05 for all tests. Results: The results showed that the mean stress, anxiety, and depression at time point of 2 weeks (P = 0.012, P < 0.0001, and P = 0.003, respectively) and stress, anxiety, and depression scores at time points of 1 month (P < 0.0001) and 3 months after delivery (P < 0.0001) were significantly lower in the study group compared with the control group. Conclusions: Inhaling the scent of lavender for 4 weeks can prevent stress, anxiety, and depression after childbirth. PMID:27095995

    Purpose of Review This review summarizes significant advances in the epidemiology, pathophysiology, and treatment of congenital hypothyroidism (CH), with a focus on thyroid dysfunction in preterm infants. Recent Findings CH appears to be increasing in incidence, primarily due to increased stringency of screening strategies, with smaller contributions from changing demographics and improved survival of increasingly premature infants. The greatest increase has been in mildly affected infants. Although many such cases are transient, some eventually prove to be severe and/or permanent. In preterm infants, transient hypothyroidism is common and may be delayed in onset. The etiology is probably multifactorial, and inadequate iodine intake may contribute to some cases. Transient hypothyroxinemia of prematurity (THOP), also common in premature infants, is correlated with markers of inflammation. Despite concern about the potential morbidity of THOP, the benefits and safety of treatment have not been established. Novel genetic causes of CH continue to be identified, and accumulating data support the sensitivity of infants with severe CH to small changes in levothyroxine formulation. Summary Changes in newborn screening strategies have increasingly identified thyroid function abnormalities of unclear clinical significance. Novel causes of CH continue to be identified, and new data continue to emerge regarding optimal therapy. PMID:23974774

    Objective: The objective of this prospective study was assessment of efficacy of bone marrow aspirate (BMA) (containing plasma rich in growth factors and mesenchymal stem cells) injection in treatment of tennis elbow. Materials and Methods: A total of 30 adult patients of previously untreated tennis elbow were administered single injection of BMA. This concentrate was made by centrifugation of iliac BMA at 2000 rpm for 20-30 min and only upper layer containing platelet rich plasma and mononuclear cells was injected. Assessment was performed at baseline, 2 weeks, 6 weeks and 12 weeks using Patient-rated Tennis Elbow Evaluation (PRTEE) score. Results: Baseline pre-injection mean PRTEE score was 72.8 ± 6.97 which decreased to a mean PRTEE score of 40.93 ± 5.94 after 2 weeks of injection which was highly significant (P < 0.0001). The mean PRTEE score at 6 week and 12 week follow-up was 24.46 ± 4.58 and 14.86 ± 3.48 respectively showing a highly significant decrease from baseline scores (P < 0.0001). Conclusion: Treatment of tennis elbow patients with single injection of BMA showed a significant improvement in short to medium term follow-up. In future, such growth factors and/or stem cells based injection therapy can be developed as an alternative conservative treatment for patients of tennis elbow, especially who have failed non-operative treatment before surgical intervention is taken.

    Critical period of weed control is the foundation of integrated weed management and, hence, can be considered the first step to design weed control strategy. To determine critical period of weed control of aerobic rice, field trials were conducted during 2010/2011 at Universiti Putra Malaysia. A quantitative series of treatments comprising two components, (a) increasing duration of weed interference and (b) increasing length of weed-free period, were imposed. Critical period was determined through Logistic and Gompertz equations. Critical period varied between seasons; in main season, it started earlier and lasted longer, as compared to off-season. The onset of the critical period was found relatively stable between seasons, while the end was more variable. Critical period was determined as 7-49 days after seeding in off-season and 7-53 days in main season to achieve 95% of weed-free yield, and 23-40 days in off-season and 21-43 days in main season to achieve 90% of weed-free yield. Since 5% yield loss level is not practical from economic view point, a 10% yield loss may be considered excellent from economic view point. Therefore, aerobic rice should be kept weed-free during 21-43 days for better yield and higher economic return. PMID:22778701

Dermatophytes, yeasts and moulds are the three major fungi responsible for skin infections. Earlier oral antifungal agents were used for treatment of fungal infection in finger and toe nails. The disadvantages of oral antifungal agents are toxicity and longer treatment period. Now medicated nail lacquers have been developed for the treatment of fungal infections i.e. onychomycosis, which has less toxicity and shorter treatment period. PMID:21369429

    This double-blind, placebo-controlled, four-way balanced design crossover study included hypertensive patients aged 60-85 years with mean office-measured sitting systolic blood pressure (SBP) 160-179 mm Hg and daytime SBP > or =135 mm Hg. After a 2-week run-in period, during which previous medications were discontinued, each patient received the following four treatments in randomized order for 4 weeks each: lercanidipine 10 mg (L), enalapril 20 mg (E), lercanidipine 10 mg plus enalapril 20 mg (L/E) and placebo (P). At the end of each treatment period, office trough blood pressure (BP) was measured and a 24-h Ambulatory Blood Pressure Monitoring (ABPM) was performed. Seventy-five patients (mean age 66 years, office BP 168/92 mm Hg, daytime SBP 151 mm Hg) were randomized and 62 completed the study with four valid post-baseline ABPMs. The administration of P, L, E and L/E was associated with a mean 24-h SBP of 144, 137, 133 and 127 mm Hg, respectively. All active treatments significantly reduced the mean 24-h SBP in comparison with placebo, but L/E was significantly more effective than L and E alone. Similarly, office SBP was significantly more reduced with L/E (-16.9 mm Hg) than with L (-5.0 mm Hg) or E (-5.9 mm Hg). A BP <140/90 mm Hg was recorded in 18% of patients with L, 19% with E and 45% with L/E. Two patients on P and two on L/E were withdrawn from the study due to adverse events. In conclusion, combination therapy with L/E has additive antihypertensive effects on both ambulatory and office BP in elderly patients and is well tolerated. PMID:17581601

    Young female rats of 160-180 g were implanted with osmotic minipumps releasing 3.0 micromol/day per kg of oleoyl-oestrone in liposomes (Merlin-2) into the bloodstream for up to 14 days. Merlin-2 induced a loss of appetite in the first days, later recovered, and a decrease in body weight of 7%, which contrasts with the 15% increase in controls during the 2-week period. Neither plasma glucose nor urea was affected by treatment, but liver glycogen increased by 50% in 14 days. Insulin decreased slightly with Merlin-2 treatment. Plasma corticotropin (ACTH) and corticosterone showed a transient increase by day 6 of treatment. The expression of the ob gene in adipose tissue fell during the period studied to practically nil on day 14; circulating leptin levels decreased more than 70% from day 1 to day 14. Oestrone levels increased from 0.3 nM (controls) to a maintained 40-60 nM level for the rest of the experiment. Oleoyl-oestrone levels first increased 4-fold, to decrease again to the initial levels on day 10, increasing later to 100-fold on day 14. The three phases observed in food intake, weight loss and oleoyl-oestrone levels match fairly well, which supports the direct involvement of oleoyl-oestrone in body-weight control. However, the control of oleoyl-oestrone levels seems to be mediated in part by corticosterone. The practical disappearance of leptin synthesis coincides with the massive accumulation of oleoyl-oestrone in plasma. The results presented suggest the involvement of oleoyl-oestrone in the main mechanisms of control of body weight and its regulation by glucocorticoids and leptin. PMID:9291105

  10. Gauge interaction as periodicity modulation

    NASA Astrophysics Data System (ADS)

    Dolce, Donatello

    2012-06-01

    The paper is devoted to a geometrical interpretation of gauge invariance in terms of the formalism of field theory in compact space-time dimensions (Dolce, 2011) [8]. In this formalism, the kinematic information of an interacting elementary particle is encoded on the relativistic geometrodynamics of the boundary of the theory through local transformations of the underlying space-time coordinates. Therefore gauge interactions are described as invariance of the theory under local deformations of the boundary. The resulting local variations of the field solution are interpreted as internal transformations. The internal symmetries of the gauge theory turn out to be related to corresponding space-time local symmetries. In the approximation of local infinitesimal isometric transformations, Maxwell's kinematics and gauge invariance are inferred directly from the variational principle. Furthermore we explicitly impose periodic conditions at the boundary of the theory as semi-classical quantization condition in order to investigate the quantum behavior of gauge interaction. In the abelian case the result is a remarkable formal correspondence with scalar QED.

  11. Epigenetics in the perioperative period

    2015-01-01

    The perioperative period is characterized by profound changes in the body's homoeostatic processes. This review seeks to address whether epigenetic mechanisms may influence an individual's reaction to surgery and anaesthesia. Evidence from animal and human studies suggests that epigenetic mechanisms can explain many facets of susceptibility to acute and chronic pain, making them potential therapeutic targets. Modern pain management is still based upon opiates, and both the developmental expression of opioid receptors and opioid-induced hyperalgesia have been linked to epigenetic mechanisms. In general, opiates seem to increase global DNA methylation levels. This is in contrast to local anaesthetics, which have been ascribed a global demethylating effect. Even though no direct investigations have been carried out, the potential influence of epigenetics on the inflammatory response that follows surgery seems a promising area for research. There is a considerable body of evidence that supports the involvement of epigenetics in the complex process of wound healing. Epigenetics is an important emerging research topic in perioperative medicine, with a huge potential to positively influence patient outcome. PMID:25073649

    Dense packings of nonoverlapping bodies in three-dimensional Euclidean space R3 are useful models of the structure of a variety of many-particle systems that arise in the physical and biological sciences. Here we investigate the packing behavior of congruent ring tori in R3, which are multiply connected nonconvex bodies of genus 1, as well as horn and spindle tori. Specifically, we analytically construct a family of dense periodic packings of unlinked tori guided by the organizing principles originally devised for simply connected solid bodies [22 Torquato and Jiao, Phys. Rev. E 86, 011102 (2012), 10.1103/PhysRevE.86.011102]. We find that the horn tori as well as certain spindle and ring tori can achieve a packing density not only higher than that of spheres (i.e., π /√18 =0.7404...) but also higher than the densest known ellipsoid packings (i.e., 0.7707...). In addition, we study dense packings of clusters of pair-linked ring tori (i.e., Hopf links), which can possess much higher densities than corresponding packings consisting of unlinked tori.

    Four nights of photoelectric observations of the delta Scuti star HR 1225 have been obtained. The light curve has a variable amplitude envelope indicating that more than one period is present. A search for periodicities using the Jurkevich method and Fourier analysis suggests periods of 0.156 d and 0.097 d. A least-squares solution yields a fair fit to the data with these two periods. The Fourier transform suggests that three periods are present.

    The Eysenck Personality Questionnaire's (EPQ) N value (neuroticism) was used to evaluate information from 158 patients before ceramic crown treatment. Patient satisfaction was also evaluated using a satisfaction questionnaire 2 weeks post treatment. Patient expectations were not correlated with sex, age, or N value, and sex was not correlated with patient satisfaction other than in relation to crown shape. Total esthetic satisfaction and feature improvement were positively correlated with age, while satisfaction for five specific criteria was negatively correlated with N value and overall expectation. These observations underscore the importance of considering the physical and psychologic aspects of patient care when planning dental treatment. PMID:27611752

    Typical symptoms of bronchiectasis include cough, sliminess of the airways and recurrent respiratory infections which lead to lung injury and impaired quality of life when untreated. High-resolution computer tomography is the most important examination to detect bronchiectasias. Cornerstones of the treatment are elucidation of the etiology of the disease, taking care of vaccinations, management of physical fitness, treating sliminess, and careful treatment of periods of exacerbation with antibiotics according to bacterial growth and susceptibility testing determined from sputum. Hypertonic saline inhalation can be used to potentiate the treatment of sliminess and achieve a positive effect on the quality of life. PMID:24822326

    Forty-eight multiparous cows were used in a randomized complete block design experiment with a 2×2 factorial arrangement of treatments to determine the interaction between chromium propionate (CrPr) supplementation and sources of corn varying in ruminal starch fermentability on production responses during the postpartum (PP) and carryover periods. During the peripartum period (28d before expected parturition until 28d PP), diets were top-dressed (20g/d) with either CrPr (KemTRACE Chromium Propionate, Kemin Industries, Des Moines, IA; 8mg of Cr/cow per day) or control (Con; ground corn). At parturition, cows were randomly assigned to corn treatment within CrPr and Con treatments: dry corn (DC) or high-moisture corn (HMC). Treatment combinations (CrPr/DC, CrPr/HMC, Con/DC, and Con/HMC) were fed from parturition until 28d PP (treatment period). Cows were fed a common diet to evaluate potential carryover effects of the treatment diets from 29 to 84d PP (carryover period). The CrPr and corn treatments interacted over time to affect yield of 3.5% fat-corrected milk (FCM) during both the treatment and carryover periods. The CrPr/HMC treatment combination tended to increase FCM compared with Con/DC and Con/HMC by 28d PP (57.4 vs. 48.6 and 48.5kg/d, respectively) and increased FCM compared with Con/DC by 42d PP (59.2 vs. 44.8kg/d). The CrPr tended to increase milk yield (55.4 vs. 51.9kg/d) regardless of corn source during the carryover period after treatment ceased. Daily and cumulative DMI were not affected by treatment during the PP period, but CrPr and corn treatments interacted over time to affect daily DMI during the carryover period; DMI was generally higher for CrPr/HMC, lower for Con/DC, and intermediate for CrPr/DC and Con/HMC from 29 to 84d PP. Supplementation of CrPr throughout the peripartum period interacted with starch source in PP diets over time to affect production responses that were sustained after treatment application ceased.

    1976-01-01

    A reliability analysis of structures subjected to random service loads and periodic proof tests treats gust loads and maneuver loads as random processes. Crack initiation, crack propagation, and strength degradation are treated as the fatigue process. The time to fatigue crack initiation and ultimate strength are random variables. Residual strength decreases during crack propagation, so that failure rate increases with time. When a structure fails under periodic proof testing, a new structure is built and proof-tested. The probability of structural failure in service is derived from treatment of all the random variables, strength degradations, service loads, proof tests, and the renewal of failed structures. Some numerical examples are worked out.

    2015-05-01

    We examine the efficiency-based arguments for second-best optimal health insurance with multiple treatment goods and multiple time periods. Correlated shocks across health care goods and over time interact with complementarity and substitutability to affect optimal cost sharing. Health care goods that are substitutes or have positively correlated demand shocks should have lower optimal patient cost sharing. Positive serial correlations of demand shocks and uncompensated losses that are positively correlated with covered health services also reduce optimal cost sharing. Our results rationalize covering pharmaceuticals and outpatient spending more fully than is implied by static, one good, or one period models. PMID:25727031

    The objective was to compare the compliance of hypertensive patients treated with captopril twice daily or trandolapril once daily. After a 2-week placebo period, hypertensive patients (diastolic BP 95-115 mm Hg) were randomly allocated to trandolapril 2 mg once daily or to captopril 25 mg twice daily for 6 months. Trandolapril and captopril were packed in electronic pill-boxes equipped with a microprocessor that recorded date and time of each opening (MEMS). Patients' compliance was assessed both by standard pill-count and by electronic monitoring. Blood pressure was measured using a validated semi-automatic device at the end of the placebo period and of the treatment period. One hundred sixty-two patients entered the study. Compliance data were evaluable for 133 patients (62 in the captopril group and 71 in the trandolapril group). Treatment groups were comparable at baseline except for age (P = .046). Using electronic pill-box, overall compliance was 98.9% in the trandolapril group and 97.5% in the captopril group (P = .002). The percentage of missed doses was 2.6% in the trandolapril group and 3.3% in the captopril group (P = .06). The percentage of delayed doses was 1.8% in the trandolapril group and 11.7% in the captopril group (P = .0001). The percentage of correct dosing periods, ie, a period with only one correct recorded opening, was 94.0% in the trandolapril group and 78.1% in the captopril group (P = .0001). Results were unchanged when adjusted for age. At the end of the study, 41% of patients in the trandolapril group and 27% in the captopril group (NS) had their blood pressure normalized (systolic BP <140 and diastolic BP <90 mm Hg). In this 6-month study, the electronic pill-box allowed refined analysis of compliance of hypertensive patients. Patients' compliance with once daily trandolapril was higher than with twice daily captopril. The between-group difference is mainly explained by an increase in delayed doses in the twice daily group. PMID

    Rectovaginal fistula is a rare complication of ulcerative colitis (UC) regardless of surgical history of rectum. Various surgical treatment modalities for the closure of rectovaginal fistula have been developed, but a radically curative therapy remains to be developed. Recently, infliximab, the chimeric anti-human tumor necrosis factor alpha (TNF-α) antibody, has been largely applied for the treatment of inflammatory bowel disease (IBD), and a few reports have shown its partial effectiveness in the management of rectovaginal fistulas associated with UC. In the present report, we describe the successful management of a rectovaginal fistula, following the stapled ileo-anal canal anastomosis in a UC patient, by administration of infliximab. The patient was a 40-year-old female, initially diagnosed as UC (total colitis type) at the age of 15. She received a restorative proctocolectomy at the age of 22, and developed a rectovaginal fistula at the eighth postoperative day. The surgical treatment of the fistula was repeated four times during the 10-year period, but it recurred in intervals ranging between 2 months and 5 years after the operation. The last recurrence occurred at the age of 32, but the surgical repair was considered difficult and a conservative management was indicated. At the age of 40, infusions of infliximab were started. Four weeks after the first infusion, drainage from the fistula was evidently reduced, and 2 weeks later, the fistula was completely closed. Thereafter, no recurrence of the fistula is observed, as confirmed by the abdominal magnetic resonance imaging (MRI) and the barium-enema study. From the present case, we concluded that infliximab may be an effective strategy for the management of fistulas associated with UC. PMID:25368705

    We studied the shortening and the number of mechanoreceptors in the patellar ligament up to 18 months after Ho-YAG irradiation of the ligament's surface in 35 rabbits. The ligaments shortened an average 13% immediately after irradiation. After treatment, we divided the rabbits into a mobilized or immobilized group. At 2 weeks and 12 months after treatment both groups showed no shortening of the ligament, as compared to the intact ligament while that in the mobilized group had elongated at 12 months. Fewer Pacinian and Ruffini corpuscles were found in the irradiated ligaments than in the intact ones at 2 weeks after treatment, but we found no difference between irradiated and intact ligaments at 18 months after treatment.

    Uveitis is an important eye disease that potentially causes loss of sight. Although extensive studies have been conducted on uveitis, the exact pathogenesis remains to be determined. The effects of treatment with natural compounds on an experimental autoimmune uveoretinitis (EAU) rat model were examined in the present study. A total of 25 rats were divided into 5 groups: Alkaloids (n=5), saponins (n=5), flavonoids (n=5), phenols (n=5), and the normal saline group (n=5). The rats in each group were treated with an intraperitoneal injection of proper alkaloids (berberine hydrochloride), saponins (steroidal saponins), flavonoids (baicalein), or phenols (chlorogenic acid) or physiological saline, respectively. The rats' aqueous humour and crystalline lens was then observed under the slit lamp periodically, looking for signs of inflammation. After 2 weeks, the rats were sacrificed and the degree of pathological changes on their eyeballs under different treatment methods were determined using an optical microscope. The expression of the interleukin (IL)-17 gene in the ocular tissues of the rats was assessed via RT-PCR and western blot analysis. Apoptosis on the rats' retinal tissues was detected using flow cytometry. The results showed that rats injected with phenols (chlorogenic acid) had serious ocular vascular dilatation, iris hemorrhage and purulent exudation; those injected with alkaloids (berberine hydrochloride) and flavonoids (baicalein) had a more mild form of inflammation; and those administered saponins (steroidal saponins) had only mild inflammation signs. Following detection of IL-17 mRNA and protein expression levels in the ocular tissues of rats of the five groups, it was found that their expression was lowest in the saponin-treated group and the other differences in expression were all statistically significant (P<0.05). A comparison with other groups revealed that cell apoptosis in the eyes of rats in the saponin group was the most prominent, reflecting

    The prevalence of Campylobacter jejuni in commercial feedlot cattle was monitored throughout the feeding period by repeated bacteriologic culture of feces. Fecal pats (n = 10) in 20 feedlot pens were sampled at 2-weeks interval beginning at entry into the feedlot and continuing until slaughter. The least-squares mean C. jejuni prevalence increased from 1.6% at the first sampling to 61.3% at the final sampling just prior to slaughter. Diverse C. jejuni pulsed-field gel electrophoresis macrorestriction profiles (MRP) were identified among the cattle isolates, but five prevalent MRP and minor variants accounted for >80% of all typed isolates. Chlorination of the water supplied to the water troughs of half of the pens did not affect C. jejuni prevalence in the cattle. Overall, the least-squares mean C. jejuni prevalences were 45.6 and 43.6% in chlorinated and nonchlorinated feedlot pens, respectively. The results of this study demonstrate apparent transmission of C. jejuni among feedlot cattle during the feeding period, unaffected by water chlorination, resulting in a high prevalence of C. jejuni excretion by cattle approaching slaughter.

    Thirty-two client-owned dogs treated for periodontal disease were divided in group 1 if no periodontitis, group 2 if ≤25%, and group 3 if >25% of the teeth present were affected with periodontitis. Blood was tested before and 2 weeks after periodontal therapy for nitrosyl hemoglobin (HbNO), plasma nitrite/nitrate (NOx) and 3-nitrotyrosine (NT) levels. No HbNO was detected in any of the animals tested. There was no significant difference in the NOx plasma levels within each group or across the groups before and after the treatment, but a noticeable increase in NOx plasma levels was observed in group 3 after the treatment. Plasma NT was detected in only one third of the animals. NO levels varied greatly across individual dogs. The data are suggestive of an overall increase in systemic NO response 2 weeks after periodontal treatment in dogs with advanced periodontal disease, but the response is greatly individually-dependent.

  6. Dearth of short-period Neptunian exoplanets: A desert in period-mass and period-radius planes

    A few studies have reported a significant dearth of exoplanets with Neptune mass and radius with orbital periods below 2-4 d. This cannot be explained by observational biases because many Neptunian planets with longer orbital periods have been detected. The existence of this desert is similar to the appearance of the so-called brown-dwarf desert that suggests different formation mechanisms of planets and stellar companions with short orbital periods. Similarly, the Neptunian desert might indicate different mechanisms of formation and evolution for hot Jupiters and short-period super-Earths. We here follow a previous study and examine the location and shape of the desert in both the period-mass and period-radius planes, using the currently available large samples of planets. The desert in the period-mass plane has a relatively sharp upper edge, with a planetary mass that is inversely proportional to the planetary orbital period, while the lower, somewhat blurred, boundary is located along masses that are apparently linearly proportional to the period. The desert in the period-radius plane of the transiting planets is less clear. It seems as if the radius along the upper boundary is inversely proportional to the period to the power of one-third, while the lower boundary shows a radius that is proportional to the period to the power of two-thirds. The combination of the two upper bounds of the desert, in the period-mass and period-radius planes, yields a planetary mass-radius relation of Rp/RJup ≃ (1.2 ± 0.3)(Mp/MJup)0.27 ± 0.11 for 0.1 ≲ Mp/MJup ≲ 1. The derived shape of the desert, which might extend up to periods of 5-10 d, could shed some light on the formation and evolution of close-in planets.

  7. Periodic Poisson model for beam dynamics simulation

    NASA Astrophysics Data System (ADS)

    Dohlus, M.; Henning, Ch.

    2016-03-01

    A method is described to solve the Poisson problem for a three dimensional source distribution that is periodic into one direction. Perpendicular to the direction of periodicity a free space (or open) boundary condition is realized. In beam physics, this approach allows us to calculate the space charge field of a continualized charged particle distribution with periodic pattern. The method is based on a particle-mesh approach with equidistant grid and fast convolution with a Green's function. The periodic approach uses only one period of the source distribution, but a periodic extension of the Green's function. The approach is numerically efficient and allows the investigation of periodic- and pseudoperiodic structures with period lengths that are small compared to the source dimensions, for instance of laser modulated beams or of the evolution of micro bunch structures. Applications for laser modulated beams are given.

    2015-01-01

    We formulate and prove a periodic analog of Maxwell’s theorem relating stressed planar frameworks and their liftings to polyhedral surfaces with spherical topology. We use our lifting theorem to prove deformation and rigidity-theoretic properties for planar periodic pseudo-triangulations, generalizing features known for their finite counterparts. These properties are then applied to questions originating in mathematical crystallography and materials science, concerning planar periodic auxetic structures and ultrarigid periodic frameworks.

  14. Circadian genes Period 1 and Period 2 in the nucleus accumbens regulate anxiety-related behavior

    It has been suggested for some time that circadian rhythm abnormalities underlie the development of multiple psychiatric disorders. However, it is unclear how disruptions in individual circadian genes might regulate mood and anxiety. Here we found that mice lacking functional mPeriod 1 (mPer1) or mPeriod 2 (mPer2) individually did not have consistent behavioral abnormalities in measures of anxiety-related behavior. However, mice deficient in both mPer1 and mPer2 had an increase in levels of anxiety-like behavior in multiple measures. Moreover, we found that mPer1 and mPer2 expression was reduced in the nucleus accumbens (NAc) after exposure to chronic social defeat stress, a paradigm that led to increased anxiety-related behavior. Following social defeat, chronic treatment with fluoxetine normalized Per gene expression towards wild-type levels. Knockdown of both mPer1 and mPer2 expression via RNA interference specifically in the NAc led to a similar increase in anxiety-like behavior as seen in the mutant animals. Taken together, these results implicate the Per genes in the NAc in response to stress and the development of anxiety. PMID:23039899

    Classical periodic orbits are stationary-phase points in path integral representations of quantum propagators. We show that complex solutions of the stationary-phase equation, not corresponding to real classical periodic orbits, give additional contributions to the propagator which can be important, especially near bifurcations. We reveal the existence and relevance of such periodic ghost orbits for a kicked top.

  11. A rare case of thyrotoxic periodic paralysis precipitated by hydrocortisone

    PubMed Central

    Chakrabarti, Subrata

    2015-01-01

    Thyrotoxic periodic paralysis (TPP) is a rare, but serious condition characterized by acute paralytic attacks and hypokalemia in association with thyrotoxicosis. Although carbohydrate rich meals, strenuous exercise, alcohol, emotional stress are known precipitants of TPP, steroid treatment has rarely been reported to induce TPP. We report a case in which a patient with previously untreated Grave's disease developed TPP following administration of Intravenous hydrocortisone for control of severe anaphylaxis, which to best of our knowledge is very rare.

    Thyrotoxic hypokalemic periodic paralysis is characterized by attacks of generalized weakness associated to hypokalemia in patients with hyperthyroidism. We report a 25-year-old man with a history of spontaneously relapsing episodes of muscular weakness, who consulted for a rapidly evolving upper and lower limb paresis. Hypokalemia associated to a primary hyperthyroidism was detected. Treatment with antithyroid Drugs and potassium supplementation reverted symptoms and the episodes of acute muscular weakness did not reappear. PMID:21279257

  13. Analysis of intermittent periodic modes within complex data

    We propose a new analytical technique, cycle length analysis (CLA), which quantifies all intermittent periodic modes of a data set. CLA is especially well suited to the treatment of extended measurements of complex physical, chemical, and biological systems when subjected to variations in underlying dynamical parameters which cannot be controlled precisely or monitored accurately. We demonstrate the application of CLA using (1) a coupled oscillator model under the conditions of continuously varying control parameters and (2) clinical cardiac rhythm data.

  14. Achieving adolescent adherence to treatment of major depression

    PubMed Central

    Staton, Dennis

    2010-01-01

    When treatments are ordered for adolescent major depression, or for other adolescent medical illnesses, adherence and clinical outcomes are likely to be unsatisfactory, unless 4 basic principles of the medical treatment of adolescent illness are implemented. These comprise providing effective patient and parent/caregiver education, establishing effective patient and caregiver therapeutic alliances, providing effective treatment, and managing other factors associated with treatment adherence as indicated. The goals of treatment are to achieve the earliest possible response and remission. Failure to treat adolescent major depression successfully has potentially serious consequences, including worsened adherence, long-term morbidity, and suicide attempt. Accordingly, prescribed treatment must be aggressively managed. Doses of an antidepressant medication should be increased as rapidly as can be tolerated, preferably every 1–2 weeks, until full remission is achieved or such dosing is limited by the emergence of unacceptable adverse effects. A full range of medication treatment options must be employed if necessary. Treatment adherence, occurrence of problematic adverse effects, clinical progress, and safety must be systematically monitored. Adolescents with major depression must be assessed for risk of harm to self or others. When this risk appears significant, likelihood of successful outcomes will be enhanced by use of treatment plans that comprehensively address factors associated with treatment nonadherence. Abbreviated and comprehensive plans for the treatment of potentially fatal adolescent illnesses are outlined in this review. PMID:24600263

    Perinatal period may pose a great challenge for the clinical management and treatment of psychiatric disorders in women. In fact, several mental illnesses can arise during pregnancy and/or following childbirth. Suicide has been considered a relatively rare event during the perinatal period. However, in some mental disorders (i.e., postpartum depression, bipolar disorder, postpartum psychosis, etc.) have been reported a higher risk of suicidal ideation, suicide attempt, or suicide. Therefore, a complete screening of mothers’ mental health should also take into account thoughts of suicide and thoughts about harming infants as well. Clinicians should carefully monitor and early identify related clinical manifestations, potential risk factors, and alarm symptoms related to suicide. The present paper aims at providing a focused review about epidemiological data, risk factors, and an overview about the main clinical correlates associated with the suicidal behavior during the pregnancy and postpartum period. Practical recommendations have been provided as well. PMID:27570512

  16. [Popular knowledge about medicaments in 19th century periodicals].

    PubMed

    Arabas, Iwona

    2004-01-01

    Polish periodicals published since the beginning of 19th century contained household knowledge which was of great importance to peasants. In the second half of 19th century the number of articles related to prevention, treatment as well as life hygiene (including nutrition guidance) enlarged significantly. The term "household medicine box# was very often used in periodicals as titles of both: sections dedicated to hygiene or medicine as well as for articles describing medicaments intended to be kept in the boxes. Articles referenced law regulations stated in "law for pharmacists and pharmacies# from 1844. The availability of medical handbooks widened with the end of the century and this fact may have caused the changes in profiles of numerous medical sections in popular periodicals. However the changes did not affect publications related to contents of medical boxes. PMID:17152882
