San Marino.  


San Marino, an independent republic located in north central Italy, in 1983 had a population of 22,206 growing at an annual rate of .9%. The literacy rate is 97% and the infant mortality rate is 9.6/1000. The terrain is mountainous and the climate is moderate. According to local tradition, San Marino was founded by a Christian stonecutter in the 4th century A.D. as a refuge against religious persecution. Its recorded history began in the 9th century, and it has survived assaults on its independence by the papacy, the Malatesta lords of Rimini, Cesare Borgia, Napoleon, and Mussolini. An 1862 treaty with the newly formed Kingdom of Italy has been periodically renewed and amended. The present government is an alliance between the socialists and communists. San Marino has had its own statutes and governmental institutions since the 11th century. Legislative authority at present is vested in a 60-member unicameral parliament. Executive authority is exercised by the 11-member Congress of State, the members of which head the various administrative departments of the goverment. The posts are divided among the parties which form the coalition government. Judicial authority is partly exercised by Italian magistrates in civil and criminal cases. San Marino's policies are tied to Italy's and political organizations and labor unions active in Italy are also active in San Marino. Since World War II, there has been intense rivalry between 2 political coalitions, the Popular Alliance composed of the Christian Democratic Party and the Independent Social Democratic Party, and the Liberty Committee, coalition of the Communist Party and the Socialist Party. San Marino's gross domestic product was $137 million and its per capita income was $6290 in 1980. The principal economic activities are farming and livestock raising, along with some light manufacturing. Foreign transactions are dominated by tourism. The government derives most of its revenue from the sale of postage stamps to collectors around the world and from payment of an annual budget subsidy by the Italian government. Despite its close ties with Italy, San Marino has maintained its distinctive status for centuries. PMID:12178101

[Oro-dental injuries during intubation anesthesia].  


Injuries to the oro-dental tissue are still one of the most frequent mishaps during endotracheal intubation and general anaesthesia. However, damage to the soft and hard tissues in most cases involves oral structures already showing advanced pathogenic alterations. Injuries to the teeth are therefore rather more often due to the disease of the teeth than to mistakes during anaesthesia. The risk of injuries to the teeth can be ascertained by means of a presurgical inspection of the oral cavity and evaluation of the individual anatomical conditions in the head and neck region, which may well interfere with the endotracheal intubation. In contrast to anaesthetic pitfalls causing severe disturbance of general health, dental trauma can be treated with quite satisfying functional and aesthetic results. However, in order to maintain conditions for the complete restitution of injured teeth immediate dental therapy is recommended. In preterm infants which need mechanical ventilation during the postnatal period direct laryngoscopy as well as mechanical alterations caused by an oral tube can cause injuries to the tooth germs of the first and second dentition and deformation of the maxillary skeleton. In consequence the patient will need intensive therapy of the resulting disturbances for several years. This review gives information about the causes and types of injuries to the oral and maxillofacial region during general anaesthesia. In addition, the anatomical conditions and pathological changes associated with an increased risk for oro-dental injuries and the facilities for prevention are discussed. Finally, the main aspects of emergency treatment of injuries to the dental hard tissues are presented. PMID:9799977

Cysts of the oro-facial region: A Nigerian experience  

PubMed Central

Aim: Though many studies have examined cysts of the jaws, most of them focused on a group of cysts and only few have examined cysts based on a particular classification. The aim of this study is to review cysts of the oro-facial region seen at a tertiary health centre in Ibadan and to categorize these cases based on Lucas, Killey and Kay and WHO classifications. Materials and Methods: All histologically diagnosed oro-facial cysts were retrieved from the oral pathology archives. Information concerning cyst type, topography, age at time of diagnosis and gender of patients was gathered. Data obtained was analyzed with the SPSS 18.0.1 version software. Results: A total of 92 histologically diagnosed oro-facial cysts comprising 60 (65.2%) males and 32 (34.8%) females were seen. The age range was 4 to 73 years with a mean age of 27.99 ± 15.26 years. The peak incidence was in the third decade. The mandible/ maxilla ratio was 1.5:1. Apical periodontal was the most common type of cyst accounting for 50% (n = 46) of total cysts observed. Using the WHO classification, cysts of the soft tissues of head, face and neck were overwhelmingly more common in males than females with a ratio of 14:3, while non-epithelial cysts occurred at a 3:1 male/female ratio. Conclusion: This study showed similar findings in regard to type, site and age incidence of oro-facial cysts compared to previous studies and also showed that the WHO classification protocol was the most comprehensive classification method for oro-facial cysts.

Oro-facial granulomatosis: a possible allergic basis.  


Food or flavouring intolerance has been demonstrated in 14 out of 80 patients with oro-facial granulomatosis. Provoking molecules include cinnamaldehyde, carvone and piperitone, although a wide range of food or flavourings may be implicated. The nature of the reaction is not understood but does not seem to involve an IgE mediated response. At present the only reliable way of detecting specific provoking factors is by the use of an elimination diet. PMID:2931101

A possible cranio-oro-facial phenotype in Cockayne syndrome  

PubMed Central

Background Cockayne Syndrome CS (Type A – CSA; or CS Type I OMIM #216400) (Type B – CSB; or CS Type II OMIM #133540) is a rare autosomal recessive neurological disease caused by defects in DNA repair characterized by progressive cachectic dwarfism, progressive intellectual disability with cerebral leukodystrophy, microcephaly, progressive pigmentary retinopathy, sensorineural deafness photosensitivity and possibly orofacial and dental anomalies. Methods We studied the cranio-oro-facial status of a group of 17 CS patients from 15 families participating in the National Hospital Program for Clinical Research (PHRC) 2005 « Clinical and molecular study of Cockayne syndrome ». All patients were examined by two investigators using the Diagnosing Dental Defects Database (D[4]/phenodent) record form. Results Various oro-facial and dental anomalies were found: retrognathia; micrognathia; high- arched narrow palate; tooth crowding; hypodontia (missing permanent lateral incisor, second premolars or molars), screwdriver shaped incisors, microdontia, radiculomegaly, and enamel hypoplasia. Eruption was usually normal. Dental caries was associated with enamel defects, a high sugar/carbohydrate soft food diet, poor oral hygiene and dry mouth. Cephalometric analysis revealed mid-face hypoplasia, a small retroposed mandible and hypo-development of the skull. Conclusion CS patients may have associated oro-dental features, some of which may be more frequent in CS children – some of them being described for the first time in this paper (agenesis of second permanent molars and radiculomegaly). The high susceptibility to rampant caries is related to a combination of factors as well as enamel developmental defects. Specific attention to these anomalies may contribute to diagnosis and help plan management.



Risk factors for onset of chronic oro-facial pain--results of the North Cheshire oro-facial pain prospective population study.  


Due to the cross-sectional nature of previous studies, whether mechanical factors predict the onset of Chronic oro-facial pain remains unclear. Aims of the current study were to test the hypotheses that self-reported mechanical factors would predict onset of Chronic oro-facial pain and that any observed relationship would be independent of the confounding effects of psychosocial factors and reporting of other unexplained symptoms. About 1735 subjects who had completed a baseline questionnaire were assessed at 2year follow-up for the presence of Chronic oro-facial pain, psychosocial factors (anxiety and depression, illness behaviour, life stressors and reporting of somatic symptoms), mechanical dysfunction (facial trauma, grinding, phantom bite and missing teeth) and reporting of other unexplained symptoms (chronic widespread pain, irritable bowel syndrome and chronic fatigue). About 1329 subjects returned completed questionnaires (adjusted response rate 87%). About 56 (5%) reported new episodes of Chronic oro-facial pain at follow-up. Univariate analyses showed that age, gender, reporting of other unexplained symptoms, psychosocial factors and two self-report mechanical factors predicted the onset of Chronic oro-facial pain. However multivariate analysis showed that mechanical factors did not independently predict onset. The strongest predictors were health anxiety (Relative Risk (RR) 2.8, 95% CI 1.3-6.2), chronic widespread pain (RR 4.0 95% C.I. 2.2-7.4) and age (RR 0.2, 95% CI 0.1-0.7). The findings from this prospective study support the hypothesis that psychosocial factors are markers for onset of Chronic oro-facial pain. The efficacy of early psychological management of Chronic oro-facial pain to address these factors should be a priority for future investigations. PMID:20304556

Prevention of oro-facial clefts in developing world  

PubMed Central

Oro-facial cleft (OFC) remains a prominent health issue in developed and developing countries alike. It is the commonest craniofacial birth defect in humans. Mounting evidence suggest a polygenic, multifactorial and a list of epigenetic events. Primary prevention of OFC is based on recognition of the etiologic and risk factors. While a number of preventive strategies are in place for OFC in most developed countries of the world, the majority of developing countries are distant from achieving this goal for a number of reasons. Notable among these are a huge knowledge and practice gap in the field of genetics and dearth of accurate data. In addition, improper coordination and absenteeism from antenatal care contributed greatly to this set back. With ongoing efforts aimed at determining the genetics of nonsyndromic OFC in developing countries, researches directed at identifying environmental factors should equally be in place. Pending the outcome of these, implicated environmental and attitudinal risk factors in other populations could serve as preventive template in health education and interventions. Since risk factors vary between populations, definitive and effective preventive strategies and models would vary from place to place and from time to time. Frantic effort directed at identifying specific implicated risk factors in developing countries should include developing and keeping comprehensive national perinatal database and centralization of antenatal care protocol. Additionally, active health education at every level and a focus on developing manpower in the field of genetics should be in place. These would be designed and tailored toward identified, proven, and emerging risk factors.

OBJECTIVE To pilot a randomized controlled trial of OROS-Methylphenidate (MPH) to treat ADHD plus epilepsy. METHOD Thirty-three patients, 6–18 years, taking antiepileptic drugs and with a last seizure 1–60 months prior were assigned to a maximum daily dose of 18, 36, or 54mg of OROS-MPH in a double-blind placebo-controlled crossover trial. RESULTS There were no serious adverse events and no carry over effects in the crossover trial. OROS-MPH reduced ADHD symptoms more than placebo treatment. There were too few seizures during the active (5) and placebo arms (3) to confidently assess seizure risk; however, considering exposure time, we observed an increased daily risk of seizures with increasing dose of OROS-MPH, suggesting that potential safety concerns need further study. CONCLUSION A larger study to assess the effect of OROS-MPH on seizure risk is needed. A crossover design including subjects with frequent seizures could maximize power and address high patient heterogeneity and recruitment difficulties.

Divergence by ADHD Subtype in Smoking Cessation Response to OROS-Methylphenidate  

PubMed Central

Introduction: Attention deficit hyperactivity disorder (ADHD) is a neuropsychiatric condition subclassified in DSM-IV according to its core symptoms domains as (a) predominantly inattentive (ADHD-IN), (b) predominantly hyperactive/impulsive (ADHD-H), and (c) combined inattentive and hyperactive/impulsive (ADHD-C). Whether these subtypes represent distinct clinical entities or points on a severity continuum is controversial. Divergence in treatment response is a potential indicator of qualitative heterogeneity. This study examined smoking cessation response by ADHD subtype to osmotic-release oral system methylphenidate (OROS-MPH). Methods: Male and female adult smokers (ADHD-C = 167 and ADHD-IN = 87) were randomized to receive OROS-MPH or placebo as augmentation treatment to nicotine patch and counseling. Logistic regression was conducted to test the effect of OROS-MPH versus placebo on prolonged smoking abstinence by ADHD subtype. Results: The subtypes were similar in baseline demographic, smoking, and psychiatric history but differed in smoking cessation response to OROS-MPH or placebo as a function of nicotine dependence level. The 3-way interaction was significant; ?2(1) = 8.22, p < .01. Among highly dependent smokers, the prolonged abstinence rates were greater with OROS-MPH than with placebo in the ADHD-C group (60% vs. 31.3%, respectively, p < .05) but higher with placebo than with OROS-MPH in the ADHD-IN group (60% vs. 11.8%, respectively, p < .01). Abstinence rates did not differ by subtype or treatment among smokers who were less nicotine dependent. Conclusion: Contrasting treatment response and divergence in the impact of nicotine dependence level support the hypothesis of ADHD subtypes as distinct clinical entities and may indicate the need and directions for personalized targeted treatments of smokers with ADHD.

Pharmacokinetic investigation of the absorption of oxprenolol from Oros delivery systems in healthy volunteers  

PubMed Central

1 The absorption kinetics of oxprenolol have been investigated in eight healthy volunteers after single dosing with 16/260 Oros drug delivery systems. Oxprenolol disposition kinetics in individual subjects were estimated from intravenous dose data. 2 Loo-Riegelman analysis of the plasma concentration data indicated an extended duration of drug absorption for the Oros system. Initially, the in vivo absorption rate was similar to the in vitro release rate but after 5-6 h it slowed perceptibly. However, at later times similar in vivo and in vitro rates were again observed. 3 The absolute bioavailabilities for prototype and clinical trial systems were shown to be similar, at approximately 42%, and no significant differences in plasma profiles or pharmacokinetic constants were detected between the two Oros forms. 4 A comparison of plasma concentration data in seven subjects who received the prototype system on two occasions in separate studies indicated a consistent level of drug absorption from this preparation. 5 Approximately 10-15% of the administered dose was found in Oros systems recovered from faeces. The quantity of drug remaining was poorly correlated with the observed areas under the plasma concentration-time curve.

Long-term efficacy and safety outcomes with OROS-MPH in adults with ADHD  

PubMed Central

Methylphenidate (MPH) is widely prescribed for adults with attention deficit hyperactivity disorder (ADHD), but data on long-term treatment and maintenance of effect are lacking. Osmotic release oral system-methylphenidate (OROS–MPH) was evaluated in a 52-wk open-label study in subjects who had previously completed a short-term placebo-controlled trial and short-term open-label extension. Efficacy was assessed using the investigator- and subject-rated Conners’ Adult ADHD Rating Scales (CAARS:O-SV and CAARS:S-S), and the Clinical Global Impression – Severity (CGI-S), Sheehan Disability Scale (SDS) and Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q). Subjects completing ?52 wk of treatment were eligible for a 4-wk randomized, placebo-controlled withdrawal phase in which loss of treatment effect was assessed using CAARS:O-SV and CGI-S. In the open-label phase (n=156), mean CAARS:O-SV score decreased from baseline by 1.9±7.8 (p<0.01), and small, statistically significant improvements from baseline were observed for CAARS:S-S, CGI-S and SDS. In the double-blind phase (OROS-MPH, n=23; placebo, n=22), CAARS:O-SV increased from double-blind baseline in the OROS-MPH and placebo arms (4.0±7.6 vs. 6.5±7.8, not statistically significant). Long-term OROS-MPH treatment was well tolerated, and there was no evidence of withdrawal or rebound after discontinuation. In conclusion, the short-term benefits of OROS-MPH continue during long-term open-label treatment. Maintenance of efficacy in a placebo-controlled withdrawal design remains to be confirmed in larger patient populations.

Development of the Chinese version of the Oro-facial Esthetic Scale.  


The aim of this study was to investigate the psychometric properties of the Oro-facial Esthetic Scale among Chinese-speaking patients. The original Oro-facial Esthetic Scale was cross-culturally adapted in accordance with the international standards to develop a Chinese version (OES-C). Unlike the original Oro-facial Esthetic Scale, the version employed in this study used a 5-point Likert scale with items rated from unsatisfactory to most satisfactory. Psychometric evaluation included the reliability and validity of the OES-C. The reliability of the OES-C was determined through internal consistency and test-retest methods. The validity of OES-C was analysed by content validity, discriminative validity, construct validity and convergent validity. The corrected item-total correlation coefficients of the OES-C ranged from 0·859 to 0·910. The inter-item correlation coefficients between each two of the eight items of the OES-C ranged from 0·766 to 0·922. The values of ICC ranged from 0·79 (95% CI = 0·54-0·98) to 0·93 (95% CI = 0·87-0·99), indicating an excellent agreement. Construct validity was proved by the presence of one-factor structure that accounted for 83·507% of the variance and fitted well into the model. Convergent validity was confirmed by the association between OES-C scores and self-reported oral aesthetics and three questions from the Oral Health Impact Profile related to aesthetics (correlation coefficients ranged from -0·830 to -0·702, P < 0·001). OES-C scores discriminated aesthetically impaired patients from healthy controls. This study provides preliminary evidence concerning the reliability and validity of the OES-C. The results show that the OES-C may be a useful tool for assessment of oro-facial esthetics in China. PMID:23829233

Left Hemisphere Specialization for Oro-Facial Movements of Learned Vocal Signals by Captive Chimpanzees  

PubMed Central

Background The left hemisphere of the human brain is dominant in the production of speech and signed language. Whether similar lateralization of function for communicative signal production is present in other primates remains a topic of considerable debate. In the current study, we examined whether oro-facial movements associated with the production of learned attention-getting sounds are differentially lateralized compared to facial expressions associated with the production of species-typical emotional vocalizations in chimpanzees. Methodology/ Principal Findings Still images captured from digital video were used to quantify oro-facial asymmetries in the production of two attention-getting sounds and two species-typical vocalizations in a sample of captive chimpanzees. Comparisons of mouth asymmetries during production of these sounds revealed significant rightward biased asymmetries for the attention-getting sounds and significant leftward biased asymmetries for the species-typical sounds. Conclusions/Significance These results suggest that the motor control of oro-facial movements associated with the production of learned sounds is lateralized to the left hemisphere in chimpanzees. Furthermore, the findings suggest that the antecedents for lateralization of human speech may have been present in the common ancestor of chimpanzees and humans ?5 mya and are not unique to the human lineage.

Oro-facial Sarcomas: A Review of 88 Cases in a Tertiary Institution in Nigeria.  


Background: A sarcoma is a malignant tumour arising from connective tissue. The word sarcoma is derived from the Greek word, sarkoma meaning fleshy growth and presents either as a soft tissue or bony tumour. Sarcomas are rare in the oro-facial region compared to oral squamous cell carcinoma. The rarity of jaw sarcomas makes diagnosis sometimes challenging and the anatomy makes aggressive treatment difficult without causing unacceptable physiological, functional and cosmetic damage to the patient. The aim of this study was to examine the demographic pattern of patients with jaw sarcomas seen at the University College Hospital, Ibadan, Nigeria over a thirty year period. MethodS: All histologically diagnosed cases of sarcomas of the oro-facial region from the Cancer Registry of the University College Hospital Ibadan and the histology records of the department of Oral Pathology, University College Hospital Ibadan from 1980-2010 were reviewed. Data was analyzed using SPSS version 18. Results: Eighty eight oro-facial sarcomas were seen consisting of sixteen different histological types. Osteogenic sarcoma was the most common type with 40 cases (45.5%). Osteogenic sarcoma occurred more in females than males with a male: female ratio of 13:27 and a mean age of 32.2years (SD±15.7). Embryonal rhabdomyosarcoma had an equal male: female distribution with mean age of 7.0 years (SD±5.2) and peak age incidence in the first decade. Conclusion: The findings in this study were generally in agreement with reports from Europe, and though, at variance with some African studies, they are mostly in agreement with large African series.

Academic, Behavioral, and Cognitive Effects of OROS® Methylphenidate on Older Children with Attention-Deficit/Hyperactivity Disorder  

PubMed Central

Abstract Objective To assess the effect of Osmotic-Release Oral System (OROS) methylphenidate (MPH) on a variety of measures evaluating academic performance, cognition, and social behavior in children with attention-deficit/hyperactivity disorder (ADHD). Methods This double-blind, randomized, placebo-controlled, crossover laboratory school study enrolled 78 children aged 9–12 years with ADHD who responded to OROS MPH. After determining individualized OROS MPH dosing (18–54?mg/day), 71 subjects received blinded treatment (OROS MPH or placebo then vice versa) on each of 2 laboratory school days, separated by 1 week. Primary efficacy was measured by Permanent Product Measure of Performance at 4 hours after study drug administration. Results Treatment with OROS MPH resulted in statistically significant improvement in Permanent Product Measure of Performance and Swanson, Kotkin, Agler, M-Flynn, and Pelham scores, measures of response time, and of working memory compared to placebo. Other measures did not meet all pre-established criteria for significance (maintenance of the overall type I error rate at 5%). Adverse events were consistent with previous reports of stimulant medications used in the management of ADHD. There were no discontinuations due to adverse events, and no serious adverse events or deaths. Conclusions OROS MPH dosed to reduce core symptoms of ADHD to within the normal range also improved performance on a variety of academic tasks in school-aged children compared to placebo. Adverse effects reported were consistent with prior studies.

The offshore Amposta Marino field, located southeast of the Ebro delta, produces from the karstified Lower Cretaceous Montsia Limestone. The field is a buried-hill structure overlain by marine clastic sediments. During drowning, the buried hill was surrounded by sea water and thus represents the typical setting in which mixing-zone corrosion is a major porosity-creating process in modern carbonates (e.g., Yucatan Peninsula, Bahamas). Mixing-zone corrosion in a clastal setting differs from freshwater karstification in that it creates an essentially horizontal zone of well-connected matrix and cave porosity. This high-porosity zone is best developed on the flanks of a structure and, ideally, has a rim-like distribution. On 3-D seismic, the authors recognize a subhorizontal reflector that cuts across the gently dipping Amposta structure. This reflector was proven by seismic-to-well matching to represent a highly porous interval. Mapping of this reflector showed that it occurs somewhat discontinuously around the western margin of the structure and fairly continuously around the eastern margin, forming a clear rim feature around the flanks of the buried hill.

Oro-palatal dysplasia Bettex-Graf--clinical findings, genetic background, treatment.  


Oro-palatal dysplasia Bettex-Graf is an extremely rare syndrome consisting of microstomia, U-shaped cleft palate and micrognathia. Only two affected families have been reported before. We present the clinical findings, treatment and 13 year follow-up in a patient with this rare syndrome. The possible linkage to the fragile site 16q22 has been supported, contrary to earlier statements of its non-pathogenic character. The analysis of clinical symptoms and reference to the literature suggests, that ankyloglossia is a part of oropalatal dysplasia, whereas hypodontia is associated with the cleft itself. The authors postulate that a 20mm intercommissural distance allows acceptable function without the need for surgical correction. PMID:22831831

Assessment of the environmental changes in Oro Lake, Mali, using MSS images  

NASA Astrophysics Data System (ADS)

Environmental changes around the Oro Lake (Mali) which, with other lakes (Fati, Faguibine, Tele), represents an important hydrological resource of the Inland Delta of the Niger river, have been assessed by means of Landsat MSS imagery analysis. After data calibration and atmospheric correction, different color composites, band ratios and image differences were selected. Subsequently, the spectral features of the principal morphological units were analyzed using the satellite data, and were compared with the morphological characteristics detected and mapped in 1957 by Tricart from field work and aerial photographs. The morphological changes highlighted by satellite data therefore represent an interesting update of the old map in a region in which it is very difficult and expensive to perform ground surveys.

Evolution of developmental pattern for vertebrate dentitions: an oro-pharyngeal specific mechanism.  


Classically the oral dentition with teeth regulated into a successional iterative order was thought to have evolved from the superficial skin denticles migrating into the mouth at the stage when jaws evolved. The canonical view is that the initiation of a pattern order for teeth at the mouth margin required development of a sub-epithelial, permanent dental lamina. This provided regulated tooth production in advance of functional need, as exemplified by the Chondrichthyes. It had been assumed that teeth in the Osteichthyes form in this way as in tetrapods. However, this has been shown not to be true for many osteichthyan fish where a dental lamina of this kind does not form, but teeth are regularly patterned and replaced. We question the evolutionary origin of pattern information for the dentition driven by new morphological data on spatial initiation of skin denticles in the catshark. We review recent gene expression data for spatio-temporal order of tooth initiation for Scyliorhinus canicula, selected teleosts in both oral and pharyngeal dentitions, and Neoceratodus forsteri. Although denticles in the chondrichthyan skin appear not to follow a strict pattern order in space and time, tooth replacement in a functional system occurs with precise timing and spatial order. We suggest that the patterning mechanism observed for the oral and pharyngeal dentition is unique to the vertebrate oro-pharynx and independent of the skin system. Therefore, co-option of a successional iterative pattern occurred in evolution not from the skin but from mechanisms existing in the oro-pharynx of now extinct agnathans. PMID:21328527

Long-term functional outcome in adult prison inmates with ADHD receiving OROS-methylphenidate.  


In a recent randomized, double-blind, placebo-controlled trial, we established a robust efficacy (Cohen's d = 2.17) of osmotic release oral system-methylphenidate (OROS-methylphenidate) delivered 72 mg daily for 5 weeks versus placebo on attention deficit hyperactivity disorder (ADHD) symptoms, global severity and global functioning in 30 adult male prison inmates with ADHD and coexisting disorders. Outcomes continued to improve during the subsequent 47-week open-label extension with OROS-methylphenidate delivered at a flexible daily dosage of up to 1.3 mg/kg body weight. In the present study, we evaluated long-term effectiveness and maintenance of improvement over the cumulated 52-week trial on cognition, motor activity, institutional behaviour and quality of life. Post hoc, we explored the associations between investigators' and self-ratings of ADHD symptoms and between ratings of symptoms and functioning, respectively. Outcomes, calculated by repeated measures ANOVA, improved from baseline until week 16, with maintenance or further improvement until week 52. Both verbal and visuospatial working memory, and abstract verbal reasoning improved significantly over time, as well as several cognition-related measures and motor activity. No substance abuse was detected and a majority of participants took part in psychosocial treatment programmes. The quality of life domains of Learning, and Goals and values improved over time; the latter domain was at open-label endpoint significantly related to improvements in attention. Investigators' and self-ratings of ADHD symptoms, as well as global symptom severity related most significantly to global functioning at week 52. Finally, investigators' and self-ratings of ADHD symptoms associated significantly at baseline with increasing convergence over time. PMID:22526730

PubMed Central

Background The main aim of this study was to compare the safety and efficacy of IR MPH administered three times daily to those of once daily OROS-MPH. Methods Subjects were outpatient adults satisfying full diagnostic criteria for DSM-IV ADHD between 19 and 60 years of age. Data from two independently conducted 6-week placebo controlled, randomized clinical trials of IR-MPH (tid) and of OROS-MPH were pooled to create three study groups: Placebo (N = 116), IR-MPH (tid) (N = 102) and OROS-MPH (N = 67). Results Eight-five percent (N = 99) of placebo treated subjects, 77% (N = 79) of the IR-MPH (tid) treated subjects, and 82% (N = 55) of the OROS-MPH treated subjects completed the 6-week trial. Total daily doses at endpoint were 80.9 ± 31.9 mg, 74.8 ± 26.2 mg, and 95.4 ± 26.3 mg in the OROS-MPH, IR-MPH (tid), and placebo groups, respectively. At endpoint, 66% (N = 44) of subjects receiving OROS-MPH and 70% (N = 71) of subjects receiving IR-MPH (tid) were considered responders compared with 31% (N = 36) on placebo. Conclusion Comparison of data from two similarly designed, large, randomized, placebo-controlled, trials, showed that equipotent daily doses of once daily OROS-MPH had similar efficacy to that of TID administered IR MPH. Trial Registration The trial of OROS-MPH was registered at, number NCT00181571.

Definitive Radiotherapy versus Postoperative Radiotherapy of Patients with Oro- and Hypopharyngeal Cancer: Impact of Prognostic Factors.  


Purpose. To compare the impact of prognostic factors of patients treated with definitive radio(chemo)therapy versus patients treated with surgery and postoperative radiotherapy for squamous cell carcinoma of the oro- and hypopharynx. Patients and Methods. 162 patients treated with definitive radiotherapy and 126 patients treated with postoperative radiotherapy were retrospectively analysed. The impact of the prognostic factors gender, age, total tumor volume (TTV), pre-radiotherapy hemoglobin level (Hb-level), tumor site, T- and N-classification, radiotherapy interruptions >5 days, radiotherapy versus simultaneous radiochemotherapy, R-status and time interval between surgery and radiotherapy were investigated. Results. The median follow-up time for the censored patients treated with definitive radio(chemo)therapy was 28.5 months and for postoperative radiotherapy 36.5 months. On univariate analysis, the TTV, Hb-level, and simultaneous radiochemotherapy had a significant impact on the survival of patients treated with definitive radio(chemo)therapy. For patients treated with postoperative radiotherapy, only the TTV showed a statistical trend for the survival (P = 0.13). On multivariate analysis, the TTV and simultaneous radiochemotherapy maintained their statistical significance for patients treated with definitive raditherapy, and the TTV, the statistical trend for patients treated with postoperative radiotherapy (P = 0.19). Conclusions. The TTV was the predominant prognostic factor for both, patients treated with definitive or postoperative radiotherapy. PMID:22315594

Association between Oro-Facial Defects and Systemic Alterations in Children Affected by Marfan Syndrome.  


Background: It is important to establish an early diagnosis of the Marfan Syndrome (MFS) for providing an adequate pharmacological or surgical therapy. Nevertheless, this diagnosis may be complex, given the multi-organic involvement of this disease. Aims: In this work, we evaluated the oral phenotype in a group of paediatric patients with a clinical diagnosis of MFS, to quantify the association of the oro-facial defects with other systemic alterations. Settings and Design: Paediatric subjects who were aged, with a clinical diagnosis of MFS, were selected from our regional Marfan monitoring unit. Methods and Material: All the patients were subjected to Paediatric Dentistry examinations and a radiological screening with Panoramic and Cephalometric X-Rays. The aortic dilation (Aortic Z-score value), the hyperlaxity of the ligaments and scoliosis were evaluated by cardio-surgical and orthopaedics specialists. Statistical Analysis: The correlations between the oral and systemic alterations were analyzed by using the chi square test for the nominal variables. Results and Conclusions: We found a significant correlation of the Aortic Z - score with multiple oral defects which included retrognathia, malar hypoplasia, cross bite, oral respiration and an ogival palate. An association of the oral defects with hyperlaxity of the ligaments and scoliosis was also found. Thus, the data suggested that dentists should be more involved in a multidisciplinary approach, to provide an early MFS diagnosis in paediatric patients. PMID:23730650

Ethnic differences in oro-facial somatosensory profiles-quantitative sensory testing in Chinese and Danes.  


Ethnic differences in pain experiences have been widely assessed in various pathological and experimental conditions. However, limited sensory modalities have been described in previous research, and the affective-motivational factors have so far been estimated to be the main mediator for the ethnic differences. This study aimed to detect the ethnic differences of oro-facial somatosensory profiles related to the sensory-discriminative dimension in healthy volunteers. The standardised quantitative sensory testing battery developed by the German Research Network on Neuropathic Pain was performed bilaterally in the infraorbital and mental regions on age- and gender-matched healthy Chinese and Danes, 29 participants each group. The influences of ethnicity, gender and test site on the somatosensory profile were evaluated by three-way anova. The ethnic disparities were also presented by Z-scores. Compared to Danes, Chinese were more sensitive to thermal detection, thermal pain, mechanical deep pain and mechanical pain rating parameters (P < 0·002) related to small fibre functions. However, the inverse results were observed for mechanical tactile modality related to large fibre function (P < 0·001) and wind-up ratio (P = 0·006). Women presented higher sensitivity compared to men. The mean Z-scores of all the parameters from Chinese group were in the normal zone created by Danish Caucasians' means and SDs. The ethnic disparities in somatosensory profile illustrated the necessity of establishing the reference data for different ethnic groups and possibly individual pain management strategies for the different ethnic groups.

Formulation and evaluation of microsphere based oro dispersible tablets of itopride hcl  

PubMed Central

Background The purpose of the present work is to mask the intensely bitter taste of Itopride HCl and to formulate an Oro dispersible tablet (ODT) of the taste-masked drug by incorporation of microspheres in the tablets for use in specific populations viz. pediatrics, geriatrics and patients experiencing difficulty in swallowing. Methods With this objective in mind, microspheres loaded with Itopride HCl were prepared by solvent evaporation method using acetone as solvent for pH-sensitive polymer, Eudragit EPO and light liquid paraffin as the encapsulating medium. The prepared microspheres were characterized with regard to yield, drug content, flow properties, particle size and size distribution, surface features, in vitro drug release and taste. The ODTs so prepared from these microspheres were evaluated for hardness, thickness, weight variation, friability, disintegration time, drug content, wetting time, water absorption ratio, moisture uptake, in vitro dispersion, in vitro disintegration, in vitro drug release and stability. Results The average size of microspheres was found to be satisfactory in terms of the size and size distribution. Microspheres prepared were of a regular spherical shape. Comparison of the dissolution profiles of microspheres in different pH media showed that microspheres having drug: polymer ratio of 1:2 produced a retarding effect in simulated salivary fluid (pH 6.8) and were further used for formulation into ODTs after addition of suitable amounts of excipients such as superdisintegrant, diluent, sweetener and flavor of directly compressible grade. Conclusions Effective taste-masking was achieved for Itopride HCl by way of preparation of microspheres and ODTs of acceptable characteristics.



Parental perceived benefits of OROS-methylphenidate treatment for the child with attention-deficit/hyperactivity disorder and for parents themselves.  


Given the shortage of studies on parental perceived benefits of OROS-methylphenidate treatment in Asian populations, we assessed parental response to OROS-methylphenidate treatment of Korean children with attention-deficit/hyperactivity disorder (ADHD), in relation to children's academic performance and behavioral symptoms as well as parental rearing stress and depressive symptoms.We enrolled 132 medication-naïve children with ADHD into a multicenter, open-label, 12-week trial of OROS-MPH. The outcome measures were the ADHD rating scale-IV (ADHD-RS), the comprehensive attention test and academic performance rating scale, and the clinical global impression (CGI)-severity/improvement instrument (for the children) and Beck depression inventory and parenting stress index (for their parents).We found parent-perceived improvements in children's ADHD-related behavioral symptoms and academic function and their parents' depressive symptoms and parenting stress. Investigator-rated ADHD symptoms and subjects' neuropsychological function were also improved (p<0.001).Parents of Korean children with ADHD perceive that OROS-methylphenidate treatment improves their children's academic function and behavior as well as their own child-rearing stress and emotional state. These findings must be interpreted with caution, due to a non-comparative open-label trial. PMID:23364873

Sustained safety and efficacy of once-daily hydromorphone extended-release (OROS® hydromorphone ER) compared with twice-daily oxycodone controlled-release over 52 weeks in patients with moderate to severe chronic noncancer pain.  


Once-daily hydromorphone extended-release (OROS(®) hydromorphone ER) and oxycodone controlled-release (CR) are semisynthetic, ER opioid analgesics with established efficacy. An open-label, randomized, 24-week, parallel group, flexible-dose study demonstrated noninferiority of OROS hydromorphone ER vs. twice-daily oxycodone CR in patients with chronic noncancer pain. In total, 112 patients were enrolled in a 28-week, open-label extension study; 60 patients received OROS hydromorphone ER and 52 received oxycodone CR. The primary efficacy measure was the change from baseline to Weeks 38 and 52 in Brief Pain Inventory item "pain right now." Global assessments of efficacy, dosing convenience, and tolerability were secondary endpoints. Mean change in "pain right now" from baseline to Week 38 was -3.0 (OROS hydromorphone ER) vs. -2.8 (oxycodone CR), and from baseline to Week 52 was -2.9 vs. -2.8; these changes were similar to the changes in the core phase (-2.1 vs. -2.1). Similar improvements were demonstrated for secondary assessments, including pain, pain interference, and quality of life. At Week 52, global assessment of efficacy was rated as "very good" or "good" by the majority of patients (OROS hydromorphone ER, 91.7%; oxycodone CR, 86.5%). More patients in the OROS hydromorphone ER group (35.0% vs. 21.2%) assessed mode of drug intake as "very convenient." The majority of patients receiving OROS hydromorphone ER (88.3%) and oxycodone CR (88.5%) rated tolerability as "good" or "very good" at Week 52; few patients discontinued treatment because of an adverse event (1.6% vs. 0.4%, respectively). The effectiveness of OROS hydromorphone ER and oxycodone CR was maintained through 1 year. PMID:22510252

Norepinephrine transporter -3081(A/T) and alpha-2A-adrenergic receptor MspI polymorphisms are associated with cardiovascular side effects of OROS-methylphenidate treatment.  


The purpose of this study was to investigate a possible association between norepinephrine genes and cardiovascular side effects of the Osmotic Controlled-Release Oral Delivery System-methylphenidate (OROS-MPH) in Korean children with attention-deficit/hyperactivity disorder (ADHD). One hundred and one children with ADHD (8.7 ± 1.7 years) were recruited from child psychiatric centers at six university hospitals in South Korea. All participants were drug-naive ADHD children treated with OROS-MPH for 12 weeks. During the treatment period the investigators titrated the OROS-MPH dosage on the basis of symptom severity and side effects. Resting heart rate (HR), diastolic blood pressure (DBP), and systolic blood pressure (SBP) were examined before and after treatment. The percentage change score (post-treatment - pretreatment/pretreatment × 100) of each parameter was calculated. Genotyping of SLC6A2 -3081(A/T) and G1287A, and alpha-2A-adrenergic receptor (ADRA2A) MspI and DraI polymorphisms was performed. Clinically significant changes were not found in cardiovascular monitoring during the course of treatment. An increase of HR after OROS-MPH treatment was found to be statistically significant (t = 3.54, p = 0.001). Changes in SBP and DBP were not significant and no specific change was found in the ECGs. However, an additive regression analysis demonstrated a significant association between SLC6A2 -3081(A/T) and percentage change in HR post-treatment (p = 0.01) after controlling for age, gender, dosage of MPH and response and baseline pulse rate. Children with ADHD having the T/T genotype of SLC6A2 showed a 12.5% increase in HR compared to baseline, whereas children with the A/T or A/A genotype showed a 3.5% and 2.5% increase after OROS-MPH treatment, respectively. There was also a significant association between the ADRA2A MspI genotype and percentage change of DBP post-treatment after controlling for age, gender, dosage of MPH and response and baseline DBP (p = 0.009). Children with ADHD having the C/C genotype of ADRA2A MspI showed an 18.5% increase in DBP compared to baseline, but children with the G/G or G/C genotype showed a 0.2% decrease after OROS-MPH treatment. The overall cardiovascular effects of OROS-MPH were modest. However, our findings show a positive association between norepinephrine-related gene polymorphisms and cardiovascular response induced by MPH in Korean children with ADHD. Consideration must be given to such children or adults with specific norepinephrine-related genotypes, especially if they show significant changes in HR or DBP after OROS-MPH administration.

Distinctive response of CNS glial cells in oro-facial pain associated with injury, infection and inflammation.  


Oro-facial pain following injury and infection is frequently observed in dental clinics. While neuropathic pain evoked by injury associated with nerve lesion has an involvement of glia/immune cells, inflammatory hyperalgesia has an exaggerated sensitization mediated by local and circulating immune mediators. To better understand the contribution of central nervous system (CNS) glial cells in these different pathological conditions, in this study we sought to characterize functional phenotypes of glial cells in response to trigeminal nerve injury (loose ligation of the mental branch), infection (subcutaneous injection of lipopolysaccharide--LPS) and to sterile inflammation (subcutaneous injection of complete Freund's adjuvant--CFA) on the lower lip. Each of the three insults triggered a specific pattern of mechanical allodynia. In parallel with changes in sensory response, CNS glial cells reacted distinctively to the challenges. Following ligation of the mental nerve, both microglia and astrocytes in the trigeminal nuclear complex were highly activated, more prominent in the principal sensory nucleus (Pr5) and subnucleus caudalis (Sp5C) area. Microglial response was initiated early (days 3-14), followed by delayed astrocytes activation (days 7-28). Although the temporal profile of microglial and astrocyte reaction corresponded respectively to the initiation and chronic stage of neuropathic pain, these activated glial cells exhibited a low profile of cytokine expression. Local injection of LPS in the lower lip skin also triggered a microglial reaction in the brain, which started in the circumventricular organs (CVOs) at 5 hours post-injection and diffused progressively into the brain parenchyma at 48 hours. This LPS-induced microglial reaction was accompanied by a robust induction of I?B-? mRNA and pro-inflammatory cytokines within the CVOs. However, LPS induced microglial activation did not specifically occur along the pain signaling pathway. In contrast, CFA injection led to minor microglial morphological changes and an induction of I?B-? mRNA in the CVO regions; a significant increase in IL-1? and IL-6 mRNA started only at 48 hours post-injection, when the induced pain-related behavior started to resolve. Our detailed analysis of CNS glial response clearly revealed that both nerve injury and oro-facial infection/inflammation induced CNS glial activation, but in a completely different pattern, which suggests a remarkable plasticity of glial cells in response to dynamic changes in their microenvironment and different potential involvement of this non-neuronal cell population in pathological pain development.

Methylphenidate extended release (OROS MPH) for the treatment of antidepressant-related sexual dysfunction in patients with treatment-resistant depression: results from a 4-week, double-blind, placebo-controlled trial.  


There are limited data to indicate effective treatment strategies for antidepressant-related sexual dysfunction, in particular for patients with treatment-resistant major depression. We subanalyzed our published data whether augmentation with methylphenidate extended release (OROS MPH) improved sexual dysfunction associated with antidepressants in patients with treatment-resistant major depression. The primary efficacy measure was the change in Arizona Sexual Experiences Survey (ASEX) from baseline to end of treatment in an intent-to-treat analysis with last observation carried forward approach. There were no significant differences between the 2 groups in terms of changes in ASEX scores over time (F1,35 = 1.14; P = 0.32), although the numerical decrease in ASEX score was greater in OROS MPH (mean change, -4.5; 20.1% decrease) than in the placebo group (mean change, -0.6; 2.6% decrease). Augmentation with OROS MPH showed no statistically significant benefit in antidepressant-related sexual dysfunction, although addition of OROS MPH to antidepressants did not worsen preexisting sexual dysfunction. Adequately powered controlled trials are needed to fully evaluate the efficacy of OROS MPH in this area. PMID:19512961

An exploration of site effects in a multisite trial of OROS-methylphenidate for smokers with Attention Deficit/Hyperactivity Disorder  

PubMed Central

Background Multi-site trials, the gold standard for conducting studies in community-based settings, can mask variability across sites resulting in misrepresentation of effects in specific sites. In a placebo-controlled trial of osmotic-release oral system methylphenidate (OROS-MPH) as augmentation treatment for smokers with ADHD, three types of sites were selected according to their clinical research specialty (ADHD, smoking cessation, and general mental health). Objective Analysis was conducted to determine if clinical outcomes, i.e., reduction in ADHD symptoms and smoking cessation rates, and the effect of treatment on these outcomes would differ by type of site. Method 255 adult smokers diagnosed with ADHD were enrolled in three clinic types: 72 in ADHD, 79 in tobacco dependence, 104 in the mental health clinics. Results The three site-types were similar in demographic characteristics, smoking history, baseline level of ADHD symptoms, and history of psychiatric illness. Site-type but not a site-type by treatment interaction predicted prolonged smoking abstinence. A significant three-way interaction of site-type, treatment, and time predicted improvement in ADHD symptoms. Moderate to strong effects of OROS-MPH relative to placebo were observed in the mental health and the ADHD clinics; a weak effect was observed in the tobacco dependence clinics. Conclusion OROS-MPH benefit varied by site for reducing ADHD symptoms but not for improving smoking abstinence. Scientific Significance Assessment of site-type effects can indicate the generalizability of findings from multisite trials and should be routinely incorporated in the design of multisite trials.

Movement of water through the thick unsaturated zone underlying Oro Grande and Sheep Creek Washes in the western Mojave Desert, USA  

NASA Astrophysics Data System (ADS)

Previous studies indicate that a small quantity of recharge occurs from infiltration of streamflow in intermittent streams in the upper Mojave River basin, in the western Mojave Desert, near Victorville, California. Chloride, tritium, and stable isotope data collected in the unsaturated zone between 1994 and 1998 from boreholes drilled in Oro Grande and Sheep Creek Washes indicate that infiltration of streamflow occurs to depths below the root zone, and presumably to the water table, along much of Oro Grande Wash and near the mountain front along Sheep Creek Wash. Differences in infiltration at sites along each wash are the result of hydrologic variables such as proximity to the mountain front, quantity of streamflow, and texture of the subsurface deposits. Differences in infiltration between the washes are the result of large-scale geomorphic processes. For example, Oro Grande wash is incised into the Victorville fan and infiltration has occurred at approximately the same location over recent geologic time. In contrast, Sheep Creek Wash overlies an active alluvial fan and the stream channel can move across the fan surface through time. Infiltration does not occur to depths below the root zone at control sites outside of the washes. Résumé. Des études précédentes indiquent qu'une faible part de la recharge est assurée par l'infiltration d'écoulement de surface dans des cours temporaires du bassin supérieur de la rivière Mojave, dans la partie occidentale du désert Mojave, près de Victorville (Californie). Des données portant sur les chlorures, le tritium et les isotopes stables, recueillies dans la zone non saturée entre 1994 et 1998 grâce à des forages réalisés dans les fonds de vallées d'Oro Grande et de Sheep Creek, montrent que l'infiltration des écoulement de surface se produit en profondeur sous la zone racinaire, et probablement jusqu'à la nappe, le long de la plus grande partie du cours de l'Oro Grande et au pied des montagnes le long de celui de Sheep Creek. Des différences dans l'infiltration aux sites le long de chacun des fonds de vallée sont la conséquence de variables hydrologiques comme la proximité du pied des montagnes, la quantité d'écoulement de surface et la texture des dépôts. Des différences dans l'infiltration entre les fonds de vallée résultent de processus géomorphologiques à grande échelle. Par exemple, le vallon de l'Oro Grande entaille le cône de déjection de Victorville et l'infiltration s'est toujours produite à peu près au même endroit lors des époques géologiques récentes. Au contraire, le fonds de la vallée de Sheep Creek passe sur un cône alluvial actif et le lit du cours d'eau peut divaguer à la surface du cône au cours du temps. L'infiltration ne se produit pas en profondeur sous la zone racinaire dans les sites hors des fonds de vallée. Resumen. Estudios previos indican que hay una pequeña contribución a la recarga por infiltración de aguas superficiales en cauces intermitentes de la cuenca del Río Mojave, en el sector occidental del Desierto de Mojave, cerca de Victorville (California, Estados Unidos de América). Los datos de cloruros, tritio e isótopos estables en la zona no saturada, registrados en sondeos perforados en los torrentes Oro Grande y Sheep Creek entre 1994 y 1998, indican que dicha infiltración tiene lugar hasta profundidades superiores a la zona radicular y, presumiblemente, hasta el nivel freático. Esto acontece en gran parte del Oro Grande Wash y cerca del frente montañoso, a lo largo del Sheep Creek Wash. Las diferencias en la infiltración en puntos de cada torrente resultan de variables hidrológicas tales como la proximidad al frente montañoso, el caudal en los cauces y la textura de los depósitos subsuperficiales. Las diferencias en la infiltración entre ambos torrentes son causadas por procesos geomórficos de gran escala. Por ejemplo, el Oro Grande Wash está encajado en el abanico de Victorville, de modo que la infiltración se ha estado produciendo en aproximadamente el mismo punto durante las époc

Predictors and impact of non-adherence in adults with attention-deficit/hyperactivity disorder receiving OROS methylphenidate: results from a randomized, placebo-controlled trial  

PubMed Central

Background Medication non-adherence has an important impact on treatment efficacy and healthcare burden across a range of conditions and therapeutic areas. The aim of this analysis was to determine predictors of non-adherence and impact of non-adherence on treatment response in adults with attention-deficit/hyperactivity disorder (ADHD). Methods Post-hoc analysis of a 13-week randomized, double-blind placebo-controlled study of OROS methylphenidate (MPH) 54 and 72 mg/day. Primary efficacy variable was the Conners’ Adult ADHD Rating Scale – Screening Version (CAARS:O-SV). Daily adherence was calculated as average daily adherence (100 × capsules taken/2), with overall adherence calculated as the average daily adherence. Predictors of adherence were assessed using mixed-effects logistic regression. Descriptive statistics were generated for change in CAARS:O-SV score for adherent (> 95% adherence) and non-adherent subjects. Predictors of change were analyzed using a mixed model. Results Subjects were allocated to OROS MPH (54 mg, n = 87; 72 mg, n = 92) or placebo (n = 97). Mean adherence was 92.6% and 93.3% (OROS MPH 54 and 72 mg/day, respectively), versus 97.5% (placebo). Adherence was higher and less variable in completers. Factors significantly associated with non-adherence included female sex, shorter time since ADHD diagnosis, higher education level (completion of university) and score on the Drug Use Screening Inventory psychiatric disorders subscale. Improvements from baseline in CAARS:O-SV score were numerically greater in subjects defined as adherent than in those who were non-adherent. Significant predictors of CAARS:O-SV change in patients who completed the study included percentage adherence up to the point of assessment (p < 0.0001), baseline score (p < 0.0001) and family history of ADHD (p = 0.0003). Conclusion The results of this analysis suggest that newly diagnosed patients, those with a high score on the DUSI-R psychiatric disorder scale, women, and subjects with high educational degrees may be at increased risk of non-adherence. Clinicians and policymakers should therefore pay special attention to these individuals, as non-adherence is a significant predictor of reduced response to treatment.

Is Alcohol an independent risk factor for Oro-Pharyngeal and Pulmonary Carcinogenesis - An Acetaldehyde concentrations based Double Blinded Randomized Control Trial  

PubMed Central

Background: There is increasing evidence that a major part of the tumour-promoting action of alcohol is mediated via its first, toxic and carcinogenic metabolite acetaldehyde. Materials & Methods: The double blinded randomized control trial was designed for 82 male volunteers aged 20-29 years. Exclusion criteria were individual under antibiotic therapy, smokers, mutant Aldehyde Dehydrogenase deficient subject or any other systemic disease. Subjects were randomized in experimental (alcohol + soft drink) and control group (soft drink) from each pair of equal body weighted volunteers. The amount of alcohol consumed was calculated to be equivalent to 0.7 g alcohol/kilogram of body weight. Samples of breath for Acetaldehyde concentration (AC) were captured with the aid of a highly reproducible fuel cell gas-sampling device (PST-M1; Lions Laboratories, Cardiff, Wales). In Statistical analysis, mean AC was compared among both groups at different interval using paired t-test and Analysis of variance. Results: Mean acetaldehyde level was recorded higher (> 50.00 ?mol/L) among interventional group which can be produced from ethanol during metabolism or by oro-pharyngeal microbes. After 15 minutes of drink, the AC was 71.36 ± 17.46 ?mol/L in ethanol group compared to 22.75 ±9.12 ?mol/L in soft-drink group. There was significant increase in AC after 1 hour (P<0.001) which was 77.58 ± 19.43 ?mol/L in ethanol group compared to 21.16 ±8.73 ?mol/L in soft-drink group. Conclusion: Although acetaldehyde is metabolite of alcohol, its organ specific production with risk for oro-pharyngeal and pulmonary carcinogenesis makes alcohol an independent risk factor of carcinogenesis.

A study on rapid confirmation of pulmonary tuberculosis in smear-negative acid fast bacilli cases by using fiberoptic bronchoscopy, done through a trans oro pharyngeal spacer  

PubMed Central

Introduction: The tuberculosis control program is based on a felt need–oriented basis. The diagnosis is mainly microbiological. However, sputum smear-negative Acid Fast Bacilli (AFB) cases with suspected radiological findings can be problematic in diagnosis. Objectives: To confirm the diagnosis of tuberculosis early, in smear-negative AFB cases by using a Fiberoptic Bronchoscope. Materials and Methods: We embarked on Fiberoptic Bronchoscopy (FOB) and Spot Scopy smear Microscopy (SSM) for 533 suspected Pulmonary Tuberculosis (PT) cases (sputum smear negative and radiologically suggestive) from February 2007 to May 2010. FOB was performed using a special device, a Trans Oro Pharyngeal Spacer (TOPS), as a conduit. Results: The yield for positivity for AFB was 341 (64%) out of 533 cases. Conclusion and Recommendation: The specimens collected by using the fiberoptic bronchoscope confirmed the disease in the smear-negative cases. Hence, FOB was recommended in smear-negative cases, to avoid delay in the treatment of tuberculosis.

First evidence of population-level oro-facial asymmetries during the production of distress calls by macaque (Macaca mulatta) and baboon (Papio anubis) infants.  


Infant distress calls are vocal communicative signals present in most animals. In nonhuman primates, they correspond to critical vocalizations for caregiving and contribute to the socio-emotional development of the individual. To our knowledge, no systematic study on the development of oro-facial hemispheric specialization in nonhuman primates infants is available. Thus, we proposed to assess to what extend emotional behaviors underlying distress calls in macaques and in baboons younger than 1 year of age may express lateralization. For the first time, a population-level cerebral lateralization was found for screaming and cooing calls in macaques and for the moaning call in baboons. However, differences in patterns of lateralization were found between the two vocalizations produced by macaques (for cooing, the left-side of the mouth opened widest than the right one and for screaming, a preference toward the right side of the mouth was noticed) as well as a sex effect for cooing. Our findings are discussed within the comparative literature in order to comprehend the ontogenetic and phylogenetic changes of hemispheric specialization for emotions in the primate order.

Crater-lake Santa Maria del Oro as a Pristine Reference for Persistent Organic Pollutants (POP' s) and Heavy Metals Content in Environmental Investigations in Western Mexico (Project Conacyt-Semarnat 2002-C01-0463, in Progress).  

NASA Astrophysics Data System (ADS)

Santa Maria del Oro Lake ( SMO) (21.37° N, 104.57° W; 750 m a.s.l.) is a quaternary crater-lake located at western Mexico in the natural border between two geological provinces: the plio-quaternary Trans-Mexican Volcanic Belt and the oligo-miocenic silicic volcanic province Sierra Madre Occidental. SMO, a tropical freshwater lake, is a warm-monomictic lake having a diameter of ca. 2 km and a mean depth at the depocenter of ca. 60 m, where three benthos cores were recovered. Contents of POP' s, total inorganic carbon (TIC), total organic carbon (TOC) and heavy metals were analyzed. Geochemistry and mineralogy also were studied in shallow sediments which corresponded to the decade of 50-60's, otherwise the beginning of industrial development of central Mexico; which is considered the possible source of emission of POP' s and heavy metals. Dioxin, furan, plaguicides and PCB' s contents were analyzed by a GC-MS applying USEPA methods. In the first 40 cm (n= 20) of the sedimentary column ( SC) the absence of POP' s was evidenced, applying a method detection limit ( MDL) of 5 ? g/ml for dioxin, furan and PCB' s. For plaguicides like chlordane and toxaphene the MDL was 0.5 ? g/ml and for plaguicides like DDT, aldrin, endrin, dieldrin, heptachlore and mirex the MDL was 5 ? g/ml. The MDL for HCB was 1 ? g/ml. The average (n= 30) for TIC, TOC and total carbon (TC) for the first 40 cm of the SC is as follows: TIC 2.4 %, TOC 3.7 % and TC 6.12 %. The average (n= 20) content (in ppm) of heavy metals for the first 20 cm of the SC is as follows: As 5.97, Cr 27.54, Cu 16.31, Ni 12.29, Pb 21.35 and Zn 82.46. These contents are roughly similar to the clarke of these metals in volcanic rocks. After the criteria of severe effect level ( SEL) of heavy metal in sediments, the content of these metals is below SEL levels. These results permit us to conclude that the sediments of SMO can be considered in unaffected state with respect to antropogenic contamination like POP' s and heavy metals. Consequently, Santa Maria del Oro Lake can be considered as a pristine reference in paleo-ecological and environmental investigations in western Mexico.

Synthetic slings: pros and cons.  


Historically, the choice of sling material for the treatment of urinary incontinence has been based on the surgeon's preference and experience. In general, pelvic surgeons have not differentiated artificial graft materials by their inherent qualities or for biocompatibility in the female pelvis and vaginal wall. The introduction of new artificial graft materials and new methods of implantation for the correction of genuine stress incontinence has generated renewed interest in the "pros and cons" associated with nonabsorbable material use. In this review, we discuss and differentiate sling materials and techniques. We consider some of the physical and biologic qualities of artificial graft materials, present theories and practices associated with the successful use of permanent grafts, and discuss the natural evolution of artificial graft slings to the current use of the tension-free vaginal tape and Suprapubic Arc Sling System (American Medical Systems, Minneapolis, MN).

540 Trans oro Pharyngeal Spacer for Inhalers  

PubMed Central

Background Many of the patients suffering from bronchial asthma (BA) and COPD do not use the inhalers properly inspite of adequate education, resulting in inadequate relief. The external spacer (es) with the inhaler needs an inspiratory rate of 25 ltsmt, not portable and costly. Also the aerosol deposition in the airways ranges from 20 to 40%only. Wheezy patients with inadequate usage of the inhalers, cleft lip and cleft palate, geriatric and odentulous category, obese asnd short neck individuals cannot take the inhalers properly. Hence an inspiratory effort independent-transoropharyngeal spacer (Tops) is developed. Inclusion criteria 1. Adults and children above 5 years of age of both sex. 2. Subjects of bronchospasm with or without comorbid cleft lip and cleft palate. Exclusion criteria 1. Patient with exaggerated gag reflux. 2. Unconscious patient. Apparatus 1. Mini Wright's Pefr Meter. 2. Tops: it is a patented device made up of ethylene vinyl acetate copolymer. It has a receptacle for the inhalers, body with an angulation of 110 degrees bent and a curved tail piece, 150 degrees. Length - 10 cms, internal diameter - 10 mm, snugly fitting in the oropharynx, the distal end overlying the epiglottis as seen in mri pharynx. 3. External spacer. 4. Salbutamol mdi. Procedure One hundred and fifty subjects (m: f 95:56), within the age range of 8 to 81 years were enrolled in the study from 1st Feb 2007 to 1 April 2007. Pefr was measured before and after the aerosol delivery using tops and external spacer as conduits at ampm respectively, coinsiding with diurnal variation of bronchomotor tone. Four children had cleft lip and palate. Results The pefr in lt/mt was grades as: below 200l (severe), 200 to 300 (moderate), 300 to 400 (mild), above 400 (very mild). There were 80 (53%) in the severe, 50 (33%) in moderate,15 (10%) mild, 5 (4%) very mild. With the tops + inhaler 80% had improvement by 60% increment of pefr (one puff-100 mcg). With the es (2 puffs–200 mcg) plus inhaler there was only 10% increment. Thus the improvement with the former was significant (P = 0.9641, r = 0.9660); radioactive isotope scan showed 80% deposition in the lungs with tops versus es (40%). A lateral study found advantage over rotahaler and nebulizer. Conclusion Inhaler with tops is a better device for delivering aerosol.

Pros and cons of phage therapy  

PubMed Central

Many publications list advantages and disadvantages associated with phage therapy, which is the use of bacterial viruses to combat populations of nuisance or pathogenic bacteria. The goal of this commentary is to discuss many of those issues in a single location. In terms of “Pros,” for example, phages can be bactericidal, can increase in number over the course of treatment, tend to only minimally disrupt normal flora, are equally effective against antibiotic-sensitive and antibiotic-resistant bacteria, often are easily discovered, seem to be capable of disrupting bacterial biofilms, and can have low inherent toxicities. In addition to these assets, we consider aspects of phage therapy that can contribute to its safety, economics, or convenience, but in ways that are perhaps less essential to the phage potential to combat bacteria. For example, autonomous phage transfer between animals during veterinary application could provide convenience or economic advantages by decreasing the need for repeated phage application, but is not necessarily crucial to therapeutic success. We also consider possible disadvantages to phage use as antibacterial agents. These “Cons,” however, tend to be relatively minor.

A ConA-like lectin from Dioclea guianensis Benth. has antifungal activity against Colletotrichum gloeosporioides, unlike its homologues, ConM and ConA.  


This study reports on the antifungal activity of Dgui, a ConA-like lectin from Dioclea guianensis seeds. Dgui inhibited conidial germination but not mycelial growth of Colletotrichum gloeosporioides. The lectins ConA and ConM from Canavalia ensiformis and Canavalia maritima, respectively, share high levels of amino acid sequence similarity (>84%) with Dgui and have the same specificity toward glucose/mannose but had no effect on the fungus. Fluorescence microscopy showed that both Dgui and ConM bind to C. gloeosporioides ungerminated conidia. However, Dgui did not bind to C. gloeosporioides germinated conidia and germ tubes and was not inhibitory to mycelial growth. Because only Dgui inhibited germination of the fungus, C. gloeosporioides conidia might have surface-specific germination targets recognized by Dgui but not by its homologues, ConM and ConA.

Cálculos ab initio con correlación electrónica  

NASA Astrophysics Data System (ADS)

Estamos entrando en una era donde la ortogonalidad entre las investigaciones de carácter experimental y de naturaleza teórica se irá difuminando progresivamente y la problemática a resolver quedará en escena como el único actor principal de la obra. Como premisa para una cooperación teórico-experimental de igual a igual, la metodología químico-cuántica utilizada debe ser capaz de ofrecer resultados de carácter predictivo. Sin duda, esta madurez en la metodología químico-cuántica ya la hemos alcanzado hace algunos años, tal y como muestra entre otras muchas, la labor que nuestro grupo ha realizado en el transcurso de la última década, dentro del campo de la Espectroscopía Teórica. Los estudios realizados comprenden una amplia gama de sistemas, variando tanto en tamaño como en complejidad, abordando problemáticas espectroscópicas consideradas tradicionalmente como especialmente controvertidas. Nuestra contribución científica más relevante reside en el carácter cuantitativo de las asignaciones espectroscópicas que hemos propuesto en base a resultados ab initio. Recordemos que en los años noventa los resultados ab initio solían presentar para las energías de excitación de sistemas de tamaño molecular moderado, como el benceno, errores de más de 1 eV. En comparación con el éxito relativo de los métodos semiempíricos, la frustración de la metodología ab initio quedaba todavía más patente. Los estudios que hemos presentado representan una comprensión profunda de los espectros electrónicos en sistemas orgánicos claves, mostrando el camino a seguir para obtener asignaciones espectroscópicas precisas (entre 0.1-0.2 eV). La naturaleza del método CASPT2 junto al diseño de estrategias computacionales nos ha permitido alcanzar el carácter cuantitativo con el que se caracterizan nuestras contribuciones[1,2]. Por todo ello, algunos de los trabajos publicados se consideran clásicos dentro del campo, pues en cierto modo definen el campo, y se reflejan en libros publicados recientemente. En la conferencia se analizarán ciertos pormenores de las investigaciones realizadas. El tipo de aplicaciones llevadas a cabo hasta la fecha se ilustrará mediante el estudio teórico del espectro electrónico de ciclooctatetraeno. Dando un paso más en la evolución de nuestra investigación, pretendemos en la actualidad describir, desde un formalismo teórico y al mismo nivel de exigencia, los mecanismos subyacentes que tienen lugar en las reacciones biológicas fototoinducidas, es decir, reacciones que se inician mediante la absorción de luz[3]. Como muestra de la caracterización de los procesos fotofísicos y fotoquímicos en fotobiología teórica, hemos elegido la descripción de la conversión interna ultrarrápida que tiene lugar en los cromóforos del ADN. Los estados excitados de las moléculas de los ácidos nucleicos presentan tiempos de vida media que se encuentran en el rango de sub-picosegundos, sugiriendo la presencia de un canal ultrarrápido de conversión interna, lo que normalmente se asocia en la fotoquímica contemporánea a una intersección cónica entre el estado excitado y el fundamental[4]. De esta forma nuestro ADN previene de forma eficaz posibles reacciones en el estado excitado y se revela como un excelente protector solar.

Pro/con a precessional geodynamo  

NASA Astrophysics Data System (ADS)

The modest amount of research that exists on the ability, or lack of ability, of mantle precession to power a geodynamo developed mostly during the last half of the 1900s. Papers by Roberts and Stewartson (1965) and by Busse (1968) studied precession generally without a pro/con conclusion. Malkus in the late 1960s attempted to advance a positive role for precession through experiments and analysis. His experiments have survived criticism, but his analyses were discounted, especially by Rochester, Jacobs, Smylie, and Chong (1975) and by Loper (1975). Rochester, et al. critiqued existing analyses of precession, including those of Malkus, but did not reach a strong position either pro or con a precessional geodynamo. Loper argued emphatically that precession was not capable of powering the geodynamo. Explicit analyses that either critique or support Loper’s arguments have yet to appear in the literature. During the 1970s, Vanyo and associates studied energy dissipation during precession of satellite liquid fuels and its effect on satellite attitude stability. Engineers and scientists in every country that has launched satellites completed similar research. Some is published in the aerospace literature, more is available in company and government reports. Beginning in 1981, Vanyo and associates applied this knowledge to the very similar problem of energy dissipation and flow patterns in precessing mechanical models scaled geometrically and dynamically to the Earth’s liquid core. Energy experiments indicate massive amounts of mechanical energy are dissipated at the CMB, and flow experiments show complex motions within the boundary layer and axial flows with helicity throughout the interior. Analysis of Earth core precession also advanced, especially in several papers by Kerswell and by Tilgner in the late 1990s. Detail numerical models have yet to appear. Although progress in understanding the role of precession in Earth core motions has advanced, there remains a common belief, often expressed explicitly, that precession is incapable of energizing a geodynamo, a la Loper. We will present a critique of Loper’s 1975 paper and briefly discuss the common practice and belief that the geodynamo must be energized by thermal and/or compositional driven convection (motion). We note here that there is no observational evidence for existence of thermal or compositional convection within the liquid core or for growth of the solid core. Although there has been considerable success in adapting data in thermal/compositional models to yield near realistic solutions, that does not constitute a proof that those models apply to the Earth. There is absolute observational evidence for mantle precession, an Earth feature that is unique, along with the Earth’s magnetic field, among the terrestrial planets. We argue that great difficulty experienced in analysis and computation of precessional flow is a major explanation for its absence in current models of the geodynamo.

Motivated by reports of synthesis of zincblende (ZB) structure CrAs in thin film form, strong interest has developed in understanding transition metal pnictides and their tendencies toward magnetic order.Literature on the experimental analysis of the structure of CoN is varied, with reports of both magnetically ordered NaCl structure CoN and non-magnetic ZB CoN. We present results of first principles analysis of electronic structure, magnetism and Murnaghan equation of state for both structures. The non-magnetic ZB structure, stable at ambient pressure transforms to a collapsed ferromagnetic NaCl phase at 10GPa (?V = -15%). These results will be compared to data and similarities/differences with other transition metal nitrides will be discussed.

RoboCon: Operator interface for robotic applications  

SciTech Connect

Carnegie Mellon U. and ORNL`s Robotics and Process Systems Division are developing a state-of-the-art robot operator control station (RoboCon) with standardized hardware and software control interfaces to be adaptable to a variety of remote and robotic equipment currently funded by DOE`s Office of Science & Technology Robotics Technology Development Program. The human operation and telerobotic and supervisory control of sophisticated and remote and robotic systems is a complex, tiring, and non-intuitive activity. Since decontamination & decommissioning, selective equipment removal, mixed waste operations, and in-tank cleanup are going to be a major future activity in DOE environmental restoration and waste management cleanup agenda, it seems necessary to utilize an operator control station and interface which maximizes operator comfort and productivity.

Neogene sequence stratigraphy, Nam Con Son Basin, offshore Vietnam  

SciTech Connect

An integrated well log, biostratigraphic, and seismic stratigraphic study of Miocene to Recent deltaic sediments deposited in the Nam Con Son Basin offshore from southern Vietnam shows the influence of eustacy and tectonics on sequence development. Sediments consist of Oligocene non-marine rift-basin fill (Cau Formation), early to middle Miocene tide-dominated delta plain to delta front sediments (TB 1.5 to TB 2.5, Due and Thong Formations), and late Miocene to Recent marine shelf sediments (TB. 2.6 to TB 3.1 0, Mang Cau, Nam Con Son, and Bien Dong Formations). Eustacy controlled the timing of key surfaces and sand distribution in the tectonically-quiet early Miocene. Tectonic effects on middle to late Miocene sequence development consist of thick transgressive systems tracts due to basin-wide subsidence and transgression, sand distribution in the basin center, and carbonate sedimentation on isolated fault blocks within the basin. Third-order sequence boundaries (SB) are identified by spore peaks, sand stacking patterns, and channel incision. In the basin center, widespread shale beds with coal occur above sequence boundaries followed by transgressive sandstone units. These TST sandstones merge toward the basin margin where they lie on older HST sandstones. Maximum flooding surfaces (MFS) have abundant marine microfossils and mangrove pollen, a change in sand stacking pattern, and often a strong seismic reflection with downlap. Fourth-order genetic-type sequences are also interpreted. The MFS is the easiest marker to identify and correlate on well logs. Fourth-order SB occur within these genetic units but are harder to identify and correlate.

Performance of the RespiCon personal aerosol sampler in forest products industry workplaces.  


The RespiCon is a multistage virtual impactor that can be used as either a personal or an area sampler. Particles collected on the first stage of the RespiCon represent the respirable fraction of airborne particulate matter. Particles collected on the first and second stages represent the thoracic fraction, and particles collected on the first, second, and third stages represent the inhalable fraction. The RespiCon is available in two versions, one with photometric aerosol detection and a gravimetric version. In this study, the performance of the gravimetric version was examined in various forest products industry facilities. The precision of the RespiCon was assessed and its performance was compared with that of both a respirable cyclone and an inhalable dust sampler. In addition, some RespiCon samples were examined using scanning electron microscopy to determine physical particle size distribution. Under the conditions of this testing, the RespiCon appeared to be reasonably precise. For most sampling locations there was a close correspondence between measurements made with the RespiCon and the CIS personal inhalable sampler or the BGI-4 respirable cyclone. The results of microscopic examination of filters from the RespiCon were consistent with expected performance characteristics. The RespiCon is a useful sampling device for those situations in which it is important to simultaneously collect either personal or area samples of the respirable, thoracic, and inhalable fractions of airborne particulate matter.

Pros and Cons of Medical Management of Ulcerative Colitis  

PubMed Central

Ulcerative colitis (UC) is a chronic inflammatory disease characterized by diffuse mucosal inflammation limited to the colon and rectum. Although a complete medical cure may not be possible, UC can be treated with medications that induce and maintain remission. The medical management of this disease continues to evolve with a goal to avoid colectomy and ultimately alter the natural history of UC. Emergence of antitumor necrosis factor-? (TNF-?) agents has expanded the medical armamentarium. 5-Aminosalicylates continue to be used in mild to moderate UC and corticosteroids are mainly used for induction of remission with immunomodulators (6-mercaptopurine/azathiopurine/methotrexate) being applied as steroid-sparing agents for maintenance therapy. Infliximab has been approved by the U.S. Food and Drug Administration and used in the treatment of moderate to severe UC; nevertheless, its use may be associated with significant adverse effects and have a negative impact on the postoperative course should the patients undergo restorative proctocolectomy. In addition, there is always a concern about patients' compliance to medical therapy, cost of medications, and risk for UC-associated dysplasia. The authors discuss the pros and cons of medications used in the treatment of UC.

Immune cascades in human intervertebral disc: the pros and cons  

PubMed Central

The unique structural hallmark of the intervertebral disc has made its central composition, the nucleus pulposus (NP), excluded from the immunologic tolerance. Consequently, the intervertebral disc is identified as an immune-privileged organ. Traditionally, local detrimental immune activities caused by NP at the lesion sites of the disc are noted as a significant factor contributing to disc degeneration. However, given the beneficial activities of immune cells in other immune-privileged sites on basis of current evidence, the degenerate disc might need the assistance of a subpopulation of immune cells to restore its structure and lessen inflammation. In addition, the beneficial impact of immune cells can be seen in the absorption of the herniated NP, which is an important factor causes the mechanical compression of nerve roots. Consequently, a modulated immune network in degenerate disc is essential for the restoration of this immune-privileged organ. Until now, the understandings of immune response in disc degeneration still rest on the harmful aspect. Further studies are needed to explore its beneficial influence. Accordingly, there are no absolutely the pros and cons in terms of immune reactions caused by NP.

Determination of composition in stoichiometric Co-N ultrathin films by nitrogen plasma sputtering  

SciTech Connect

This work utilizes low-energy sputtering to incorporate the generated nitrogen plasma into an epitaxial 1.4 nm Co film on the surface of a ZnO(002) substrate. In this method, ultrathin Co-N amorphous films were formed. Interestingly, Co is key to the formation of Co-N films. Without the deposition of Co on the ZnO(002), nitride films cannot be formed. Observations of the surface composition of the Co-N films after the firing of a N{sup +} ion beam onto it demonstrated that the surface concentration of Co reduced at the same rate as the reduction in the concentration of N upon successive sputtering. Theoretical calculations based on the Auger peak-to-peak amplitudes established that the composition of the amorphous Co-N thin films may be Co{sub 3}N{sub 2}.

The purpose of this document is to release, into the Hanford Document Control System, FA1/0991, Sludge Particle Separation Efficiencies for the Rectangular SCS-CON-230 Container, by M. Epstein and M. G. Plys, Fauske & Associates, LLC, June 2009. The Sludge Treatment Project (STP) will retrieve sludge from the 105-K West Integrated Water Treatment System (IWTS) Settler Tanks and transfer it to container SCS-CON-230 using the Settler Tank Retrieval System (STRS). The sludge will enter the container through two distributors. The container will have a filtration system that is designed to minimize the overflow of sludge fines from the container to the basin. FAI/09-91 was performed to quantify the effect of the STRS on sludge distribution inside of and overflow out of SCS-CON-230. Selected results of the analysis and a system description are discussed. The principal result of the analysis is that the STRS filtration system reduces the overflow of sludge from SCS-CON-230 to the basin by roughly a factor of 10. Some turbidity can be expected in the center bay where the container is located. The exact amount of overflow and subsequent turbidity is dependent on the density of the sludge (which will vary with location in the Settler Tanks) and the thermal gradient between the SCS-CON-230 and the basin. Attachment A presents the full analytical results. These results are applicable specifically to SCS-CON-230 and the STRS filtration system's expected operating duty cycles.




Evaluation of the ACT*DE*CON{sup SM} process for treating gunite tank sludge  

SciTech Connect

A test was conducted to evaluate this process for selectively removing actinides from Gunite tank sludge. Mixed waste sludge from Gunite tank W-6 was subjected to the ACT*DE*CON selective leaching process. (Nearly all the TRU content was attributed to Pu.) The sludge sample was first washed with 0.01M NaOH to remove excess sodium and nitrate in the interstitial liquid supernatant. The washed wet solids were treated with the ACT*DE*CON solvent (aqueous carbonate solution containing a chelating agent and an oxidant), using a ratio of 20 ml solvent per gram wet solids. Sludge and solvent were separated by centrifugation, and the ACT*DE*CON treatment was repeated twice. Analyses showed that 71% of the solids in the sludge were dissolved while 80% of the TRU-waste components dissolved. Low separation of the TRU-waste components from other components of the sludge mixture is indicated. Almost all the U and Ca were removed from the sludge. For sludges where most of the TRU content is Pu, the ACT*DE*CON process as tested is not effective in rendering the sludge a non-TRU waste. It is recommended that ACT*DE*CON be optimized for this specific application and that other processes using different chelating and oxidizing agents be tested. Also, the ACT*DE*CON process should be tested on TRU mixed waste in which most of the TRU elements are not Pu.

Pros and cons: prospective predictors of marijuana use on a college campus.  


Marijuana use on college campuses is prevalent and associated with high rates of abuse and dependence. The Marijuana Decisional Balance (MDB) scales measure perceived pros and cons toward marijuana use. Evidence supports reliability and concurrent validity of these scales, but the predictive validity has not yet been assessed. The current study evaluated the prospective predictive validity of pros and cons scales for marijuana use, as well as explored predictive validity for marijuana problem indicators. Secondary analyses included test-retest reliability and internal consistency, to provide additional evidence of psychometric properties. A total of 149 college students (57% recent marijuana users, 77% lifetime users) participated in a baseline survey, then completed a second survey one month later. All provided data on marijuana pros and cons, as well as use status in the past month. Users at each time point reported on use frequency, problems, and disorder symptoms. In the month between assessments, 55% of the students used marijuana. Both pros and cons subscales prospectively predicted use status in the subsequent month, but not use frequency. Pros prospectively predicted marijuana problems and dependence symptoms at follow-up, and remained a significant predictor of later dependence symptoms even after controlling for baseline dependence symptoms. In contrast, pros only marginally predicted abuse. Cons did not predict problems, abuse, or dependence symptoms. Pros and cons showed strong test-retest reliability (rs = 0.80-0.85) and internal consistency (alphas = 0.92-0.95). In a college sample, pros and cons of marijuana use demonstrated stability over one month, and prospectively predicted use. Pros may also have utility in predicting problems and dependence potential on college campuses. PMID:22985053

Influence of in vitro irradiation upon LIF production by ConA stimulated mononuclear cells  

SciTech Connect

Leukocyte migration inhibitory factor (LIF) activity of culture supernatants of in vitro irradiated Concanavalin A (ConA) stimulated lymphocytes was tested by measuring granulocyte migration from clotted plasma droplets placed in flat bottom microplates. The specificity of inhibition was assured by pretreating the assay supernatants with anti-LIF antibodies which abrogated granulocyte migration inhibition but did not impair guinea pig Peritoneal Exudate Cells (PEC) migration inhibition. In vitro irradiation (150-1200 rad) of MNC cultures either before or after ConA stimulation did not impair lymphokine production and sometimes significantly improved the supernatants' LIF activity as compared with that of unirradiated cultures. The existence of radiosensitive suppressor cells regulating LIF production by ConA stimulated mononuclear cells is suggested.

Se determinan edades en términos de los tipos SWB y se identifican 38 cúmulos tipo VII, muchos de los cuales pueden ser cúmulos globulares clásicos. El tamaño de las distribuciones espaciales crece uniformemente con la edad (tipo SWB), en tanto que existe una diferencia en el cociente axial entre los grupos más jóvenes y más viejos que 30 millones de años, lo que implica una orientación aproximadamente de frente para los primeros y una posición inclinada ~ 45o para el segundo grupo. Las asimetrías en las distribuciones espaciales, juntamente con la falta de coincidencia de los centroides de los diferentes grupos de edad, sugiere que el disco de la Nube Mayor de Magallanes fue severamente perturbado en el pasado.

Null alleles for salivary Concanavalin A-binding (Con A) and Po proteins at PRB2 and PRB4 loci  

SciTech Connect

Six closely linked PRP (proline-rich protein) genes code for many salivary PRPs which show frequent null variants especially. The Con polymorphism includes the different sized Con 1 and Con 2 proteins and the null Con 0 form. N-terminal amino acid sequences (60 aa) were determined on Con 1 and Con 2 proteins. From comparison of the protein sequences with those deduced from published PRP DNA sequences, Con proteins are probably encoded within exon 3 of the PRB2 gene. Both PRB2 alleles were then cloned from an individual with the Con1/Con 2 phenotype and one PRB2 allele from the individual with the Con 0 phenotype. From DNA sequence analysis, Con 1 is probably a 124 aa protein that is derived by proteolytic processing from a larger precursor, and there are two signals (NKS) for asparagine-linked carbohydrate attachment. However, from the n-terminal protein sequence, the first site is not used. A single nucleotide substitution in the Con 0 allele causes a coding change mutation [TCT (Ser){yields}CCT(Pro)] that abolishes the postulated single functional carbohydrate attachment site (NKS{yields}NKP) and explains the absence of Con 1 protein staining on the Western blot in Con 0 homozygotes. The n-terminal sequence of the Con 2 protein was not encoded in either PRB2 allele from the individual with the Con 1/Con 2 phenotype and must be encoded by another PRB locus. The non-glycosylated 70 aa Po protein which shows Po+ and Po- phenotypes was known to be encoded by exon 3 of the PRB4 gene. The DNA sequence from exon 3 of PRB4 from an individual with the Po- phenotype was compared to that previously published from a Po+ individual. A nucleotide substitution was found at the {open_quotes}invariant{close_quotes} +1 position [GT{yields}CT] of the exon 3 5{prime}-splice site. This mutation adequately accounts for the Po- phenotype.

Single flap reconstruction for complex oro-facial defects using chimeric free fibular flap variants.  


In this article, we describe the use of chimeric free fibular flaps to reconstruct three-dimensional spatial defects in the orofacial region. Recent insights into permutations possible with the chimeric fibular flap have allowed us to achieve our reconstructive objectives with a single chimeric flap and minimise donor-site morbidity as well as operating time. In an overall series of 34 free fibular flaps from 2009 to 2012, we performed twelve cases of free chimeric fibular flaps with osseo-myo-cutaneous/OMC (n=7), multi-pedicled osseo-musculo-cutaneous/Mp-OMC (n=4) and multi-pedicled osseo-cutaneous/Mp-OC (n=1) variants for either post-excisional defects or osteo-radionecroses. We had an overall flap survival rate of 100% with one partial flap loss due to the 'puppeteer' effect. Based on our experiences, we find the chimeric fibular flap to be an excellent addition to our reconstructive arsenal for complex orofacial defects. PMID:23177211

Immunostimulatory activity of ConBr: a focus on splenocyte proliferation and proliferative cytokine secretion.  


Lectins constitute a class of glycoproteins, which are capable of selectively and reversibly binding to carbohydrates, distinguishing small structural differences in complex oligosaccharides. Studies have shown that the binding of lectins to cell-surface carbohydrates can lead to various effects such as cellular proliferation, histamine release and cytokine production. Canavalia brasiliensis lectin (ConBr) is a (D-mannose) D-glucose lectin. In this study, murine splenocytes were cultured to determine the effect of ConBr on cell proliferation, nitric oxide (NO) release and cytokine secretion. In addition, cellular viability assays were performed to evaluate any mitogenic activity induced by this lectin. ConBr significantly increased cell proliferation with minimal cell damage. This lectin was able to induce an increased production of cytokines such as IL-2, IL-6 and IFN-? and a decreased production of IL- 10. The release of NO was also observed. The results of this study indicate that ConBr could potentially be used as an immunomodulator. PMID:22009293

Probing of Brain States in Real-Time: Introducing the ConSole Environment  

PubMed Central

Recent years have seen huge advancements in the methods available and used in neuroscience employing EEG or MEG. However, the standard approach is to average a large number of trials for experimentally defined conditions in order to reduce intertrial-variability, i.e., treating it as a source of “noise.” Yet it is now more and more accepted that trial-to-trial fluctuations bear functional significance, reflecting fluctuations of “brain states” that predispose perception and action. Such effects are often revealed in a pre-stimulus period, when comparing response variability to an invariant stimulus. However such offline analyses are disadvantageous as they are correlational by drawing conclusions in a post hoc-manner and stimulus presentation is random with respect to the feature of interest. A more direct test is to trigger stimulus presentation when the relevant feature is present. The current paper introduces Constance System for Online EEG (ConSole), a software package capable of analyzing ongoing EEG/MEG in real-time and presenting auditory and visual stimuli via internal routines. Stimulation via external devices (e.g., transcranial magnetic stimulation) or third-party software (e.g., PsyScope X) is possible by sending TTL-triggers. With ConSole it is thus possible to target the stimulation at specific brain states. In contrast to many available applications, ConSole is open-source. Its modular design enhances the power of the software as it can be easily adapted to new challenges and writing new experiments is an easy task. ConSole is already pre-equipped with modules performing standard signal processing steps. The software is also independent from the EEG/MEG system, as long as a driver can be written (currently two EEG systems are supported). Besides a general introduction, we present benchmark data regarding performance and validity of the calculations used, as well as three example applications of ConSole in different settings. ConSole can be downloaded at:

ConBr, a lectin from Canavalia brasiliensis seeds, protects against quinolinic acid-induced seizures in mice.  


Lectins are proteins capable of reversible binding to carbohydrates or glycoconjugates. In the central nervous system of mammals, lectins with affinity for mannose/glucose or galactose can modulate cellular communication. ConBr, a lectin isolated from the seeds of Canavalia brasiliensis, previously showed antidepressant effect in the forced swimming test in mice, with involvement of the monoaminergic system. In this study, we investigated the neuroprotective effects of ConBr against quinolinic acid (QA), a well-known NMDA agonist that produces severe neurotoxicity when administered in vivo. ConBr (10 ?g/site) administered via intracerebroventricular (i.c.v.) showed a neuroprotective activity against seizures induced by QA (36.8 nmol/site; i.c.v.) when administered 15 min prior to QA, with a percentage of protection around 50%. ConBr was also able to significantly decrease the severity of the seizures but without changes in the latency of the first convulsion or the duration of the seizures. This effect was dependent on the structural integrity of the ConBr protein and its binding capacity to oligosaccharides residues. ConA, a lectin with high similarity to ConBr, did not reverse the QA-induced seizures. Moreover, ConBr was able to protect against hippocampal cell death caused by QA, which was measured by propidium iodide incorporation. QA caused activation of JNK2 and improved the phosphorylation of Ser831 and 845 on the AMPA receptor GluR1 subunit, and both of these effects were counteracted by ConBr. Our data suggest that the lectin ConBr may exert a modulatory action on NMDA receptors, which inhibits its activity in response to QA. PMID:21948344

Mound-ACT*DE*CON{sup SM} feasibility study. Phase 2: Final report  

SciTech Connect

A portion of the abandoned Miami-Erie Canal paralleling the Greater Miami River receives the runoff and storm-water discharge from Mound Laboratory. In 1969, a low-level plutonium leak contaminated sediment as far away as 1.5 mi from the Mound site along the old canal system. An estimated one million cubic feet of sediment requires remediation. The technology being evaluated for the remediation of the low-level plutonium-238 contamination of the sediment involves two processes: washing the sediments with ACT*DE*CON{sup SM} solution to dissolve the contaminant, followed by extraction of the solution and processing with the MAG*SEP{sup SM} process to concentrate the contaminant and allow reuse of the ACT*DE*CON{sup SM} solution. The processes are being optimized for pilot-scale and field demonstration. Phase 2 of the project primarily involved identification at the laboratory scale of the optimal ACT*DE*CON{sup SM} formulation, identification of the ion-exchanger and MAG*SEP{sup SM} particles, verification of the plutonium mobility in the treated soil, and evaluation of other process parameters according to a series of tasks.

Combined, in this paper, with the absorption exceeding the Carbon NanoTube (CNT) band-gap (?bg=~1/CNT diameter) with an active short wave near-infrared (SWIR) (1.2~1.5 micron wavelengths), which happened to be translucent to the irradiation upon animal skin, similar to that used in hospital fingertip-clamped Pulse Oxymetry. Once the Con_ACNT is guided to hepatoma cells, it is bonded and internalized into the mitochondria (MC) compartment, the cellular energy factory. Con_A has the higher specificity for tumor cells useful for targeting because of the abnormal glycosylation on tumor cells. When CNT hitch hike with Con_A, they can t together like a laser-denotable chemical missile surgically targeting at the tumor cells precisely by Con_A-guidance. We switch on SWIR laser, when the Con_A-CNT conjugated complex has been bonded and internalized to MC of malign cells and already commenced cellular programmed death. Thus, it might appear to casual readers that we have initiated an overkill, chemical drugged autophage followed with physical laser ablation, but what if we can eradicate hepatoma totally if no blue print is left behind inadvertently in case of a partial failure. We conclude that using Con_A-CNT conjugated complex targeting specifically at malign tumor cells is a novel targeted-laser-radiation therapy for tumors in mice.

Con A induction of IgG secretion from a B-lymphoid tumour cell line, A20.  

PubMed Central

We have examined the effect of concanavalin A (Con A), a conventionally known T-cell mitogen, on the induction of Ig secretion from BALB/c B lymphoid cell lines expressing membrane IgM (X16C8.5, BALENTL 17.7.2 and BCL1) or membrane IgG (A20 and M12.4). A20 tumour cells, but not other tumour cells, responded to Con A by secreting Ig as measured by the reverse plaque-forming cell (PFC) assay. Another typical T-cell mitogen, phytohaemagglutinin (PHA), did not have any effect on the differentiation of A20 tumour cells. The addition of NaN3 abolished the PFC formation, showing that IgG PFC formation of A20 tumour cells was due to the active synthesis of secreted IgG and not due to the shedding of mIgG. The increase in the biosynthesis of secreted IgG from A20 tumour cells by Con A was also observed by polyacrylamide gel electrophoresis. The ability of Con A to induce IgG secretion from A20 tumour cells was abolished by the addition of alpha-methylmannoside, confirming that Con A itself, and not some contaminating material in Con A, induced the maturation of A20 tumour cells. Con A was also shown to induce Ig secretion, but not proliferation, in a subset of normal B cells. Thus, we conclude that Con A does give a differentiation signal to a subset of B cells.

Effect of GonaCon™ vaccine on black-tailed prairie dogs: immune response and health effects.  


Management of prairie dogs in the past has included poisoning, fumigants, barriers, and relocation. Because of the diverse attitudes related to prairie dog management, nonlethal methods that allow the existence of prairie dogs but help minimize damage related to population growth need to be developed. GonaCon™ is an immunocontraceptive vaccine that elicits antibodies to native GnRH; this prevents the secretion of reproductive hormones necessary for sperm and oocyte production. Prairie dogs were vaccinated with 0.1, 0.2, or 0.4 mL of the GonaCon™ emulsion intramuscularly in the upper thigh containing 100, 200, or 400 ?g GnRH conjugate, respectively. Control animals were vaccinated with 0.4 mL saline emulsion in the upper thigh. Blood samples (?1 mL) were taken from the femoral vein once pretreatment and at 1, 2, 3, 4, 6, and 15 months post-vaccination. Age (adult or juvenile) did not affect immune response to GonaCon™. Antibody titers were higher in the 200 and 400 ?L GonaCon™ groups than in the 100 ?L group, and there was no difference between the 200 and 400 ?L GonaCon™ groups. No adverse effects of GonaCon™ were noted on weight or blood chemistry parameters during the study. GonaCon™ will likely contracept prairie dogs for ?1 year in the field using either 200 or 400 ?g conjugate. GonaCon™ could be incorporated into management plans to help maintain prairie dog populations while reducing habitat degradation due to overpopulation. PMID:21055491

ConMap: Investigating new computer-based approaches to assessing conceptual knowledge structure in physics  

NASA Astrophysics Data System (ADS)

There is a growing consensus among educational researchers that traditional problem-based assessments are not effective tools for diagnosing a student's knowledge state and for guiding pedagogical intervention, and that new tools grounded in the results of cognitive science research are needed. The ConMap (``Conceptual Mapping'') project, described in this dissertation, proposed and investigated some novel methods for assessing the conceptual knowledge structure of physics students. A set of brief computer-administered tasks for eliciting students' conceptual associations was designed. The basic approach of the tasks was to elicit spontaneous term associations from subjects by presenting them with a prompt term, or problem, or topic area, and having them type a set of response terms. Each response was recorded along with the time spent thinking of and typing it. Several studies were conducted in which data was collected on introductory physics students' performance on the tasks. A detailed statistical description of the data was compiled. Phenomenological characterization of the data (description and statistical summary of observed patterns) provided insight into the way students respond to the tasks, and discovered some notable features to guide modeling efforts. Possible correlations were investigated, some among different aspects of the ConMap data, others between aspects of the data and students' in-course exam scores. Several correlations were found which suggest that the ConMap tasks can successfully reveal information about students' knowledge structuring and level of expertise. Similarity was observed between data from one of the tasks and results from a traditional concept map task. Two rudimentary quantitative models for the temporal aspects of student performance on one of the tasks were constructed, one based on random probability distributions and the other on a detailed deterministic representation of conceptual knowledge structure. Both models were reasonably successful at approximating the statistical behavior of a typical student's data.

Nitrogen-detected CAN and CON experiments as alternative experiments for main chain NMR resonance assignments  

PubMed Central

Heteronuclear direct-detection experiments, which utilize the slower relaxation properties of low ? nuclei, such as 13C have recently been proposed for sequence-specific assignment and structural analyses of large, unstructured, and/or paramagnetic proteins. Here we present two novel 15N direct-detection experiments. The CAN experiment sequentially connects amide 15N resonances using 13C? chemical shift matching, and the CON experiment connects the preceding 13C? nuclei. When starting from the same carbon polarization, the intensities of nitrogen signals detected in the CAN or CON experiments would be expected four times lower than those of carbon resonances observed in the corresponding 13C-detecting experiment, NCA-DIPAP or NCO-IPAP (Bermel et al. 2006b; Takeuchi et al. 2008). However, the disadvantage due to the lower ? is counteracted by the slower 15N transverse relaxation during detection, the possibility for more efficient decoupling in both dimensions, and relaxation optimized properties of the pulse sequences. As a result, the median S/N in the 15N observe CAN experiment is 16% higher than in the 13C observe NCA-DIPAP experiment. In addition, significantly higher sensitivity was observed for those residues that are hard to detect in the NCA-DIPAP experiment, such as Gly, Ser and residues with high-field C? resonances. Both CAN and CON experiments are able to detect Pro resonances that would not be observed in conventional proton-detected experiments. In addition, those experiments are free from problems of incomplete deuterium-to-proton back exchange in amide positions of perdeuterated proteins expressed in D2O. Thus, these features and the superior resolution of 15N-detected experiments provide an attractive alternative for main chain assignments. The experiments are demonstrated with the small model protein GB1 at conditions simulating a 150 kDa protein, and the 52 kDa glutathione S-transferase dimer, GST.

Lesbian (in)visibility in Italian Renaissance culture: Diana and other cases of donna con donna.  


Current conceptualizations of sexual identity in the West are not necessarily useful to an historian investigating "lesbianism" in the social history and visual representations of different periods. After an overview of Renaissance documents treating donna con donna relations which examines the potentially positive effects of condemnation and silence, the paper focuses on Diana, the goddess of chastity, who bathed with her nymphs as an exemplar of female bodies preserved for heterosexual, reproductive pleasures. Yet the self-sufficiency and bodily contact sometimes represented in images of this secluded all-female gathering might suggest "deviant" responses from their viewers. PMID:7798609

An aggregation of pro and con evidence for medical decision support systems.  


One promising way to increase the classification accuracy of medical decision support systems is to implement heuristic combinations of pattern recognition and artificial intelligence tools. A parallel between "cognition" model and differential diagnostic task is sketched accentuating the aggregation of activating and restraining inputs and corresponding PRO and CON evidence in medicine. On the basis of this paradigm a trainable model of a fuzzy neuron is proposed which resembles some elements from the physician's decision process. An example from aviation medicine is presented which demonstrates the enhanced performance. PMID:8306621

Quick fix or long-term cure? Pros and cons of bariatric surgery  

PubMed Central

The past decade has seen an enormous increase in the number of bariatric, or weight loss, operations performed. This trend is likely to continue, mirroring the epidemic of obesity around the world and its rising prevalence among children. Bariatric surgery is considered by many to be the most effective treatment for obesity in terms of maintenance of long-term weight loss and improvement in obesity-related comorbid conditions. Although overly simplified, the primary mechanisms of the surgical interventions currently utilized to treat obesity are the creation of a restrictive or malabsorptive bowel anatomy. Operations based on these mechanisms include the laparoscopic adjustable gastric band and laparoscopic vertical sleeve gastrectomy (considered primarily restrictive operations), the laparoscopic biliopancreatic diversion with or without a duodenal switch (primarily malabsorptive operation), and the laparoscopic Roux-en-Y gastric bypass (considered a combination restrictive and selective malabsorptive procedure). Each operation has pros and cons. Important considerations, for the patient and surgeon alike, in the decision to proceed with bariatric surgery include the technical aspects of the operation, postoperative complications including long-term nutritional problems, magnitude of initial and sustained weight loss desired, and correction of obesity-related comorbidities. Herein, the pros and cons of the contemporary laparoscopic bariatric operations are reviewed and ongoing controversies relating to bariatric surgery are discussed: appropriate patient selection, appropriate operation selection for an individual patient, surgeon selection, and how to measure success after surgery.

Preparation of stimulus responsive multiple emulsions by membrane emulsification using con a as biochemical sensor.  


In this work, a novel strategy for the controlled fabrication of biomolecular stimulus responsive water-in-oil-in-water (W/O/W) multiple emulsion using the membrane emulsification process was investigated. The emulsions interface was functionalized with a biomolecule able to function as a receptor for a target compound. The interaction between the biomolecular receptor and target stimulus activated the release of bioactive molecules contained within the structured emulsion. A glucose sensitive emulsion was investigated as a model study case. Concanavalin A (Con A) was used as the biomolecular glucose sensor. Various physicochemical strategies for stimulus responsive materials formulation are available in literature, but the preparation of biomolecule-responsive emulsions has been explored for the first time in this paper. The development of novel drug delivery systems requires advanced and highly precise techniques to obtain their particular properties and targeting requirements. The present study has proven the flexibility and suitability of membrane emulsification for the preparation of stable and functional multiple emulsions containing Con A as interfacial biomolecular receptor able to activate the release of a bioactive molecule as a consequence of interaction with the glucose target molecule. The influence of emulsion interfacial composition and membrane emulsification operating conditions on droplets stability and functional properties have been investigated. The release of the bioactive molecule as a function of glucose stimulus and its concentration has been demonstrated. PMID:21404264

[AnaConDa as last resort treatment. Case report of a chronic obstructive pulmonary disease].  


Treatment of patients suffering from decompensated chronic pulmonary disease (COPD) not responding to pharmacological therapy is still a major challenge in intensive care medicine. Administration of volatile anaesthetics may be a therapy of last resort in these cases. We report on a 65-year-old woman suffering from exacerbated COPD, who could not be sufficiently ventilated despite comprehensive pharmacological therapy. In order to administer a volatile anaesthetic in the ICU, we employed the "Anaesthetic Conserving Device" (AnaConDa) consisting of a vaporizer chamber embedded in a charcoal filter system. With this device, every standard intensive care ventilator can be used to deliver volatile anaesthetics in a safe and economic manner. The AnaConDa converts the open breathing system of the intensive care ventilator into a de facto half-closed system. The very low pulmonary compliance of the patient increased dramatically after administration of 0.75 vol% halothane for 48 h (27 vs. 150 ml/mbar). Elimination of CO(2) was improved and weaning from controlled ventilation was achieved. After surgical removal of a pulmonary abscess and a total of 78 days of intensive care therapy, the patient was discharged in good health. PMID:17375268

Field performance of the RespiCon for size-selective sampling of industrial wood processing dust.  


The RespiCon sampler is a multistage virtual impactor that simultaneously collects the ISO/CEN/ACGIH size fractions of inhalable, thoracic, and respirable particulate matter. The field performance of the device for measurement of industrial wood processing dust was evaluated against reference size-selective samplers: the IOM sampler (inhalable dust), the GK 2.69 cyclone (thoracic dust), and the SKC aluminum cyclone (respirable dust). Seventy-one sets of area samples were collected from 10 wood processing plants, with the samplers mounted either in the free-field or on a two-dimensional bluff body. The geometric mean (range) dust levels across all plants measured by the reference samplers were: inhalable, 1.35 mg/ m3 (0.11-11.06); thoracic, 0.31 mg/m3 (0.05-1.38); and respirable, 0.10 mg/m3 (0.02-0.54). In comparing the RespiCon with the reference samplers, there was no significant difference between sampling in the free-field versus bluff-body modes. For inhalable dust, there was no significant difference between the RespiCon and the IOM sampler after applying a correction factor of 1.5 to the extrathoracic data obtained from the RespiCon. Without the correction factor, the RespiCon undersample inhalable dust by an average of 23%. For thoracic dust, the RespiCon was shown to oversample the extrathoracic dust fraction resulting in an overall error of 48%. A simple correction based on the inhalable and thoracic dust levels reported by the RespiCon is proposed. For respirable dust, there was a significant difference between the RespiCon and the SKC cyclone, but the data were equivocal due to imprecision in measurement of the low respirable dust concentrations encountered and the likelihood of bias in the reference sampler. Overall, the RespiCon sampler appears to be a suitable size-selective sampling device for industrial wood processing dust, although adjustments should be made to the inhalable and thoracic dust results.

A con-focal setup for micro-XRF experiments using diamond anvil cells  

NASA Astrophysics Data System (ADS)

In this contribution we introduce an experimental setup to perform con-focal micro X-ray fluorescence measurements in situ in samples at high temperatures and pressures in diamond anvil cells (DAC) (e.g. Schmidt et al. 2007). The con-focal arrangement is used to suppress the background in X-ray fluorescence (XRF) spectra that stems from elastic and inelastic scattering of the diamond anvils. The setup is based on a focusing optic in the incident beam that reaches a spot of 5-10 ?m and a focusing poly-capillary in front of an energy-dispersive solid-state detector. The detector poly-capillary is designed to work at a very long working distance of 50 mm in order to collect the radiation from the center of the DAC at 90° to the incident beam. The probing volume is defined by the two foci and has a size of ca. 300 ?m at 8 keV and 150 ?m at 19 keV as measured by scans through thin metal foils. Comparison of XRF spectra acquired with a usual detector collimator and spectra recorded with the detector capillary shows a strong suppression of XRF signal generated outside the probed volume, i.e. XRF from the gasket material and signal from elastic and Compton scattering by the diamond anvils. The ratio of the Zr K-alpha fluorescence peak to the peak of the Compton scattering changes from 0.5 (collimator) to 1.26 (detector capillary) for a ca. 1000 ppm Zr standard solution and an incident beam energy of 20 keV. For a standard solution containing ca. 1000 ppm Hf, the ratio of the L-alpha to the Compton signal increases to 6 using the detector capillary and an incident beam energy of 9.7 keV. Thus, the con-focal setup substantially improves the fluorescence to background ratio. This will result in higher sensitivities for dilute elements in the sample chamber of the DAC. Furthermore, the possibilities of interference of the sample's signal with signal from the sample environment are greatly reduced. In a broader sense, the setup can also be applied to other confined samples that require long working distances. Schmidt et al. (2007) Lithos 95, 87-102

Multi-wall carbon nanotube-polyaniline biosensor based on lectin-carbohydrate affinity for ultrasensitive detection of Con A.  


In this paper, a novel method for detecting concanavalin A (Con A) was developed based on lectin-carbohydrate biospecific interactions. Multi-wall carbon nanotube-polyaniline (MWNT-PANI) nanocomposites, synthesized by in situ polymerization, were chosen to immobilize d-glucose through the Schiff-base reaction. The immobilized D-glucose showed high binding sensitivity and excellent selectivity to its target lectin, Con A. Cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), transmission electron microscopy (TEM) and atomic force microscopy (AFM) were applied to characterize the assembly process of the modified electrode. Due to the high affinity of Con A for D-glucose and high stability of the propounded sensing platform, the fabricated biosensor achieved ultrasensitive detection of Con A with good sensitivity, acceptable reproducibility and stability. The changes of response current were proportional to the Con A concentrations from 3.3 pM to 9.3 nM, with a detection limit of 1.0 pM. Therefore, the combination of MWNT-PANI nanocomposites and the special binding force between lectin and carbohydrate provides an efficient and promising platform for the fabrication of bioelectrochemical devices.

Methane activation by cobalt cluster cations, Con+ (n=2-16): Reaction mechanisms and thermochemistry of cluster-CHx (x=0-3) complexes  

NASA Astrophysics Data System (ADS)

The kinetic energy dependences of the reactions of Con+ (n=2-16) with CD4 are studied in a guided ion beam tandem mass spectrometer over the energy range of 0-10 eV. The main products are hydride formation, ConD+, dehydrogenation to form ConCD2+, and double dehydrogenation yielding ConC+. These primary products decompose to form secondary and higher order products, ConCD+, Con-1D+, Con-1C+, Con-1CD+, and Con-1CD2+ at higher energies. Adduct formation of ConCD4+ is also observed for the largest cluster cations, n>=10. In general, the efficiencies of the single and double dehydrogenation processes increase with cluster size, although the hexamer cation shows a reduced reactivity compared to its neighbors. All reactions exhibit thresholds, and cross sections for the various primary and secondary reactions are analyzed to yield reaction thresholds from which bond energies for cobalt cluster cations to D, C, CD, CD2, and CD3 are determined. The relative magnitudes of these bond energies are consistent with simple bond order considerations. Bond energies for larger clusters rapidly reach relatively constant values, which are used to estimate the chemisorption energies of the C, CD, CD2, and CD3 molecular fragments to cobalt surfaces.

Pro-Con Debate: Etomidate or Ketamine for Rapid Sequence Intubation in Pediatric Patients  

PubMed Central

When caring for critically ill children, airway management remains a primary determinant of the eventual outcome. Airway control with endotracheal intubation is frequently necessary. Rapid sequence intubation (RSI) is generally used in emergency airway management to protect the airway from passive regurgitation of gastric contents. Along with a rapid acting neuromuscular blocking agent, sedation is an essential element of RSI. A significant safety concern regarding sedatives is the risk of hypotension and cardiovascular collapse, especially in critically ill patients or those with pre-existing comorbid conditions. Ketamine and etomidate, both of which provide effective sedation with limited effects on hemodynamic function, have become increasingly popular as induction agents for RSI. However, experience and clinical investigations have raised safety concerns associated with both etomidate and ketamine. Using a pro-con debate style, the following manuscript discusses the use of ketamine versus etomidate in RSI.

Intramolecular Hydrogen Bond in Alkoxyamines. Influence on the C-ON Bond Homolysis.  


The C-ON bond homolysis in alkoxyamines can be influenced by the presence of an intramolecular hydrogen bond (IHB) between the alkyl and the nitroxyl fragments, which leads to an 8-fold decrease in the homolysis rate constant kd. When the IHB is disrupted by the solvent or by substitution of the hydrogen involved in the IHB by a protecting group (OMe, OAc, OBz, OBn, or OTBDMS), a higher homolysis rate constant kd is observed, as expected from the correlations developed by Marque ( Bertin , D. ; Gigmes , D. ; Marque , S. ; Tordo , P. Macromolecules 2005 , 38 , 2638 - 2650 ). Results were confirmed by DFT calculations at the B3LYP/6-31G(d,p) level. PMID:24070391

A maritime navigation display that provides visual feedback to improve conning officers' ship-handling during low visibility environments.  


Navigating a ship at night in close proximity to another vessel is a dangerous task. To improve conning officers' night time ship-handling performance, a visual navigation display is proposed that is mounted on the stern of the aircraft carrier that will help shipboard conning officers manoeuvre in a battle group formation. To test the effectiveness of the visual navigation display, the Nimitz-class aircraft and plane guard vessel, a Ticonderoga-class cruiser, were modelled in a virtual environment. A navigation display condition had significantly fewer navigational positional errors than a non-navigation display condition. The navigation display provided immediate feedback as to whether the aircraft carrier had changed bearing or speed, thus enabling the operator to initiate the appropriate input to maintain station astern of the carrier. Actual or potential applications of this research include the deployment of a maritime navigation display to assist conning officers' ship handling. PMID:12569043

Direct activation of murine resting T cells by con A or anti-CD3 Ig.  


The induction of antigen-specific T cell activation is highly dependent on accessory cells (AC) which present processed antigenic fragments associated with MHC molecules and provide costimulatory signals for T cells. Antigen-specific T cell activation requires cross-linking of the TCR and the reception of one or more nonantigen-specific signals which eventually lead to T cell activation and proliferation. This sequence of events can be mimicked by lectins, bacterial enterotoxins, and anti-TCR antibodies in conjunction with APC or the combination of phorbol esters and Ca ionophores. Although the combination of PMA + Ca ionophore and certain types of T-T interactions result in APC independent T cell activation, it is generally assumed that physiologic T cell activation requires APC. The seemingly direct activation of T cells by other T cells is rather surprising in view of the known APC dependence of antigen, lectin and anti-TCR mediated T cell activation. It is conceivable that T cell mediated T cell activation is due to "cryptic" APC contamination because the total absence of APC is difficult to disprove. In reality, neither total depletion nor residual contamination with APC can be proven or disproven experimentally. Thus it can be legitimately argued that both APC dependent and independent T cell activation occur, albeit under different experimental conditions. For instance, it is possible that APC independent activation of T cells by lectins and anti-TCR antibodies would require high concentrations of activators to overide their dependence on APC. It is also conceivable and, in our opinion quite likely, that once activated, T cells could propagate T cell activation through T-T interactions. In this report we test two hypotheses: (1) The triggering of resting T cells leading to autocrine cell proliferation depends entirely on cross-linking TCR molecules, and (2) The presence of activated T cells facilitates TCR mediated activation of resting T cells without the participation of conventional APC. We present evidence that highly purified, small resting T cells can be reproducibly activated with high doses of ConA, plastic bound anti-CD3 mab and its F(ab')2 fragments. This APC independent response results in blastic transformation, expression of the IL2 Receptor, the secretion of IL2 and significant proliferation of both CD4+ and CD8+ murine T cells. These observations demonstrate that vigorous cross-linking of TCRs by anti-CD3 mab and, presumably ConA, is sufficient to induce T cell activation and autocrine (IL2 driven) proliferation.(ABSTRACT TRUNCATED AT 400 WORDS) PMID:2532886

Treatment of plutonium contaminated soil/sediment from the Mound site using the ACT*DE*CON{sup SM} process  

SciTech Connect

The removal and/or treatment of contaminated soil is a major problem facing the US DOE. The EG&G Mound Applied Technologies site in Miamisburg, Ohio, has an estimated 1.5 million cubic feet of soils from past disposal and waste burial practices awaiting remediation from plutonium contamination. This amount includes sediment from the Miami-Erie Canal that was contaminated in 1969 following a pipe- rupture accident. Conventional soil washing techniques that use particle separation would generate too large a waste volume to be economically feasible. Therefore, innovative technologies are needed for the cleanup. The ACT*DE*CON process was developed by SELENTEC for washing soils to selectively dissolve and remove heavy metals and radionuclides. ACT*DE*CON chemically dissolves and removes heavy metals and radionuclides from soils and sediments into an aqueous medium. The ACT*DE*CON process uses oxidative carbonate/chelant chemistry to dissolve the contaminant from the sediment and hold the contaminant in solution. The objective of recent work was to document the proves conditions necessary to achieve the Mound-site and regulatory-cleanup goals using the ACT*DE*CON technology.

Strains arising by seismic events in the SIRGAS-CON network region  

NASA Astrophysics Data System (ADS)

In this study, we investigate surface strains related to seismic events and their relationship with pre- and post-seismic events in Latin America, by analyzing the variation of estimated earth coordinates supplied by a geodetic network called SIRGAS-CON. Based on data provided by the USGS for the period 2000-2011, and after the Global Congruency test, we selected four events associated with unstable geodetic network points. The resulting strains were estimated based on the finite element method using networks of points considered unstable connected to neighboring points using the Delaunay triangulation. It was possible to determine the strains along with the resulting guidelines for pre- and post-seismic, considering each triangular lattice formed for analysis as a homogeneous solid body. The calculation of strains and verification of the results allowed to analyze the interactions between lithospheric plates from the contraction and extension directions between points located in different plates. Despite the association between seismic events and the strain of geodetic network, some events of magnitude greater than 5.8 Mw were excluded because it does not show (provide) the surface strain, which is located at great depths. It was confirmed that events of greater magnitude provide increased surface strain rate when compared with other similar depths.

Long-Acting Injectable Antipsychotics for First-Episode Schizophrenia: The Pros and Cons  

PubMed Central

Clinical and psychosocial deterioration associated with schizophrenia occurs within the first few years following the onset of the illness. Therefore, to improve the long-term prognosis, it is important to provide schizophrenia patients with intensive treatment following their first episode. Relapse is highly associated with partial medication adherence or nonadherence in patients with first-episode schizophrenia. Recent studies suggest that long-acting injectable (LAI) antipsychotics compared with oral antipsychotics are more effective for medication adherence and relapse prevention. Moreover, some clinical guidelines for the treatment of schizophrenia suggested that LAI antipsychotics should be considered when patients are nonadherent “at any stage.” Decreased compliance is a common cause of relapse during the initial stages of the disease. Therefore, LAI antipsychotics should be highly considered when treating patients with first-episode schizophrenia. In the present paper, clinical trial data and current guidelines on the use of LAI antipsychotics for first-episode schizophrenia are discussed as well as the pros and cons of this treatment option.

Pro con debate: the use of regional vs systemic analgesia for neonatal surgery.  


In recent years the inclusion of regional techniques to pediatric anesthesia has transformed practice. Simple procedures such as caudal anesthesia with local anaesthetics can reduce the amounts of general anesthesia required and provide complete analgesia in the postoperative period while avoiding large amounts of opioid analgesia with potential side effects that can impair recovery. However, the application of central blocks (epidural and spinal local anesthesia) via catheters in the younger infant, neonate and even preterm neonate remains more controversial. The potential for such invasive maneuvers themselves to augment risk, can be argued to outweigh the benefits, others would argue that epidural analgesia can reduce the need for postoperative ventilation and that this not only facilitates surgery when intensive care facilities are limited, but also reduces cost in terms of PICU stay and recovery profile. Currently, opinions are divided and strongly held with some major units adopting this approach widely and others maintaining a more conservative stance to anesthesia for major neonatal surgery. In this pro-con debate the evidence base is examined, supplemented with expert opinion to try to provide a balanced overall view. PMID:21722227

[Emission spectrum of liquid CO-N2 mixture at shock compression].  


Driving a copper projectile to impact a cryo-target made of aluminous alloy at the speed of 2.21 km x s(-1) with a two stage light gas gun, a proper one dimensional shockwave with a speed of 18.76 km x s(-1) was generated and directly acted on a uniform liquid in target, which was condensed by proportional gaseous carbon monoxide and nitrogen. At the measurement of Hugoniots, the full linear spectrum entirely dissociated with the plasma under the shock pressure of 33.5 GPa was caught by the use of intensified charge coupled device and accurate spectrographic technology. From the analysis of the spectrum, the authors know that the transient spectrograph with six channels can be used to measure and record the course of shock compression-irradiancy reliably, and the emitted spectral lines of shock compressed products indicated that the thermal dissociation and phase transition had occurred in homogeneous liquid of CO-N2. Furthermore, comparing the spectral intensity of lower central wavelength with that of higher, the fact of stronger intensity of 488 nm also validates that changes from "optic thin" to "optic thick" exist indeed in dense hydrocarbon liquid acted on by shock pressure.

Chemically triggered C-ON bond homolysis in alkoxyamines: regioselectivity and chemoselectivity.  


Recently, we examplified the activation of the C-ON bond homolysis by protonation, alkylation, benzylation, acylation, oxidation and complexation with a Lewis acid of the nitrogen atom of the 1-(pyridin-4-yl)ethyl fragment (Chem. Commun., 2011, 4291 and Org. Lett., 2012, 358) and of the 1-(pyridin-2-yl)ethyl fragment (J. Org. Chem. ASAP Doi:10.1021/jo401674v) of (N-(2-methylpropyl)-N-(1-diethylphosphono-2,2-dimethylpropyl)-N-oxyl) SG1-based alkoxyamines. The quaternization of the 1-(pyridin-3-yl)ethyl fragment by the aforementioned reactions was investigated for the corresponding SG1-based alkoxyamines. In sharp contrast to the quaternization at ortho and para positions of the pyridyl moiety, the effect of the quaternization at the meta position was weak. The effects of quaternization at ortho, meta and para positions were investigated through natural bond orbital and Mulliken charges, HOMO-LUMO interactions in the starting materials and the radical stabilization energy of the released 1-puridylmethyl radicals using DFT calculations with the B3LYP/6-31G(d) and UBMK/6-311+G(3df,2p)//R(O)B3LYP/6-31G(d) methods, respectively.

Do Patient-perceived Pros and Cons of Opioids Predict Sustained Higher-Dose Use?  


OBJECTIVES:: Chronic opioid therapy (COT) is associated with various adverse outcomes, especially at higher doses, yet little is known about predictors of sustained higher-dose COT. This study aimed to ascertain, among higher-dose COT patients, the association of patient-perceived pros and cons of opioids with continued higher-dose use 1 year later. METHODS:: Patients (N=1229) in 2 large health plans prescribed ?50 mg morphine-equivalent dose (MED) per day for chronic noncancer pain completed a survey assessing opioid benefits and harms. The Prescribed Opioid Difficulties Scale questionnaire assessed psychosocial problems, concerns, benefits, and side effects related to opioid use. Logistic regression models estimated the associations of the reported benefits and problems with higher-dose continuation (?50 mg MED/d) versus dose reduction (<50 mg MED/d) 1 year later. RESULTS:: Over 80% of participants continued higher-dose opioid use at 1 year, regardless of reported problems, concerns, side effects, pain reduction, or perceived helpfulness. Higher scores on the Prescribed Opioid Difficulties Scale Problems subscale (odds ratio=0.79, 95% confidence interval, 0.68-0.92) and Concerns subscale (odds ratio=0.76, 95% confidence interval, 0.65-0.90) were negatively associated with higher-dose use 1 year later. Other baseline measures (opioid helpfulness, reduction in pain, number of side effects, and side effect bothersomeness) were not significantly associated with continued higher-dose use. DISCUSSION:: The large majority of patients continued using higher-dose opioids regardless of baseline characteristics. These findings suggest the difficulty of reducing opioid dose among chronic higher-dose opioid users. PMID:23535150

Strain rate of the South American lithospheric plate by SIRGAS-CON geodetic observations  

NASA Astrophysics Data System (ADS)

A multiyear solution of the SIRGAS-CON network was used to estimate the strain rates of the earth surface from the changing directions of the velocity vectors of 140 geodetic points located in the South American plate. The strain rate was determined by the finite element method using Delaunay triangulation points that formed sub-networks; each sub-network was considered a solid and homogeneous body. The results showed that strain rates vary along the South American plate and are more significant on the western portion of the plate, as expected, since this region is close to the subduction zone of the Nazca plate beneath the South American plate. After using Euler vectors to infer Nazca plate movement and to orient the velocity vectors of the South American plate, it was possible to estimate the convergence and accommodation rates of the Nazca and South American plates, respectively. Strain rate estimates permitted determination of predominant contraction and/or extension regions and to establish that contraction regions coincide with locations with most of the high magnitude seismic events. Some areas with extension and contraction strains were found to the east within the stable South American plate, which may result from different stresses associated with different geological characteristics. These results suggest that major movements detected on the surface near the Nazca plate occur in regions with more heterogeneous geological structures and multiple rupture events. Most seismic events in the South American plate are concentrated in areas with predominant contraction strain rates oriented northeast-southwest; significant amounts of elastic strain can be accumulated on geological structures away from the plate boundary faults; and, behavior of contractions and extensions is similar to what has been found in seismological studies.

Iliac crest autograft versus alternative constructs for anterior cervical spine surgery: Pros, cons, and costs  

PubMed Central

Background: Grafting choices available for performing anterior cervical diskectomy/fusion (ACDF) procedures have become a major concern for spinal surgeons, and their institutions. The “gold standard”, iliac crest autograft, may still be the best and least expensive grafting option; it deserves to be reassessed along with the pros, cons, and costs for alternative grafts/spacers. Methods: Although single or multilevel ACDF have utilized iliac crest autograft for decades, the implant industry now offers multiple alternative grafting and spacer devices; (allografts, cages, polyether-etherketone (PEEK) amongst others). While most studies have focused on fusion rates and clinical outcomes following ACDF, few have analyzed the “value-added” of these various constructs (e.g. safety/efficacy, risks/complications, costs). Results: The majority of studies document 95%-100% fusion rates when iliac crest autograft is utilized to perform single level ACDF (X-ray or CT confirmed at 6-12 postoperative months). Although many allograft studies similarly quote 90%-100% fusion rates (X-ray alone confirmed at 6-12 postoperative months), a recent “post hoc analysis of data from a prospective multicenter trial” (Riew KD et. al., CSRS Abstract Dec. 2011; unpublished) revealed a much higher delayed fusion rate using allografts at one year 55.7%, 2 years 87%, and four years 92%. Conclusion: Iliac crest autograft utilized for single or multilevel ACDF is associated with the highest fusion, lowest complication rates, and significantly lower costs compared with allograft, cages, PEEK, or other grafts. As spinal surgeons and institutions become more cost conscious, we will have to account for the “value added” of these increasingly expensive graft constructs.

Immunoreactivity for Thymosin Beta 4 and Thymosin Beta 10 in the Adult Rat Oro-Gastro-Intestinal tract  

PubMed Central

Thymosin beta 4 (T?4) and thymosin beta 10 (T?10) are two members of the ?-thymosin family, involved in multiple cellular activities in different organs in multiple animal species. Here we report the expression pattern of T?4 and T?10 in rat tissues, in the gut and in annexed glands. The two peptide were differently expressed: T?4 was absent in salivary glands whereas T?10 was expressed in parotid and in submandibular glands. T?4 was mildly expressed in the tongue and in the esophagus, where T?10 was absent. A similar expression was found in the stomach, ileum and colon mucosa. In pancreas T?4 reactivity was restricted to the Langerhans islet cells; T?4 was also detected in the exocrine cells. Both peptide were not expressed in liver cells. When the rat expression pattern in rat organs was compared to reactivity for T?4 and T?10 in humans, marked differences were found. Our data clearly indicate a species-specific expression of T?4 and T?10, characterized by the actual unpredictability of the expression of these peptides in different cells and tissues. The common high expression of T?4 in mast cells, both in humans and in rats, represents one of the few similarities between these two species.

Development, characterization and clinical use of a biodegradable composite scaffold for bone engineering in oro-maxillo-facial surgery  

PubMed Central

We have developed a biodegradable composite scaffold for bone tissue engineering applications with a pore size and interconnecting macroporosity similar to those of human trabecular bone. The scaffold is fabricated by a process of particle leaching and phase inversion from poly(lactideco-glycolide) (PLGA) and two calcium phosphate (CaP) phases both of which are resorbable by osteoclasts; the first a particulate within the polymer structure and the second a thin ubiquitous coating. The 3–5 ?m thick osteoconductive surface CaP abrogates the putative foreign body giant cell response to the underlying polymer, while the internal CaP phase provides dimensional stability in an otherwise highly compliant structure. The scaffold may be used as a biomaterial alone, as a carrier for cells or a three-phase drug delivery device. Due to the highly interconnected macroporosity ranging from 81% to 91%, with macropores of 0.8?1.8 mm, and an ability to wick up blood, the scaffold acts as both a clot-retention device and an osteoconductive support for host bone growth. As a cell delivery vehicle, the scaffold can be first seeded with human mesenchymal cells which can then contribute to bone formation in orthotopic implantation sites, as we show in immune-compromised animal hosts. We have also employed this scaffold in both lithomorph and particulate forms in human patients to maintain alveolar bone height following tooth extraction, and augment alveolar bone height through standard sinus lift approaches. We provide a clinical case report of both of these applications; and we show that the scaffold served to regenerate sufficient bone tissue in the wound site to provide a sound foundation for dental implant placement. At the time of writing, such implants have been in occlusal function for periods of up to 3 years in sites regenerated through the use of the scaffold.

Plasmonic tunable glucose sensing based on the dissociation of Con A-aggregated dextran-coated gold colloids  

NASA Astrophysics Data System (ADS)

We have recently developed a new approach to glucose sensing based on the aggregation of nanometer-sized noble-metal nanoparticles and their respective change in plasmon absorption upon glucose addition. High molecular weight Dextran coated nanoparticles are aggregated with Concanavalin A, (Con A), where the aggregation results in a significant shift in metal-plasmon absorption. The addition of glucose competitively binds to Con A, reducing nanoparticle aggregation, and therefore the plasmon absorption when monitored at 650 nm. We have optimized our plasmonic glucose sensing mechanism with regard to nanoparticle stability, the dynamic range for glucose sensing and the wavelength of observation, to be compatible with both clinical glucose requirements and measurements.

Structural analysis of ConBr reveals molecular correlation between the carbohydrate recognition domain and endothelial NO synthase activation.  


Diocleinae lectins are highly homologous in their primary structure which features metal binding sites and a carbohydrate recognition domain (CRD). Differences in the biological activity of legume lectins have been widely investigated using hemagglutination inhibition assays, isothermal titration microcalorimetry and co-crystallization with mono- and oligosaccharides. Here we report a new lectin crystal structure (ConBr) extracted from seeds of Canavalia brasiliensis, predict dimannoside binding by docking, identify the ?-aminobutyric acid (Abu) binding pocket and compare the CRD of ConBr to that of homologous lectins. Based on the hypothesis that the carbohydrate affinity of lectins depends on CRD configuration, the relationship between tridimensional structure and endothelial NO synthase activation was used to clarify differences in biological activity. Our study established a correlation between the position of CRD amino acid side chains and the stimulation of NO release from endothelium. PMID:21530490

Comparison of four probabilistic models (CARES(®), Calendex™, ConsExpo, and SHEDS) to estimate aggregate residential exposures to pesticides.  


Two deterministic models (US EPA's Office of Pesticide Programs Residential Standard Operating Procedures (OPP Residential SOPs) and Draft Protocol for Measuring Children's Non-Occupational Exposure to Pesticides by all Relevant Pathways (Draft Protocol)) and four probabilistic models (CARES(®), Calendex™, ConsExpo, and SHEDS) were used to estimate aggregate residential exposures to pesticides. The route-specific exposure estimates for young children (2-5 years) generated by each model were compared to evaluate data inputs, algorithms, and underlying assumptions. Three indoor exposure scenarios were considered: crack and crevice, fogger, and flying insect killer. Dermal exposure estimates from the OPP Residential SOPs and the Draft Protocol were 4.75 and 2.37?mg/kg/day (crack and crevice scenario) and 0.73 and 0.36?mg/kg/day (fogger), respectively. The dermal exposure estimates (99th percentile) for the crack and crevice scenario were 16.52, 12.82, 3.57, and 3.30?mg/kg/day for CARES, Calendex, SHEDS, and ConsExpo, respectively. Dermal exposure estimates for the fogger scenario from CARES and Calendex (1.50 and 1.47?mg/kg/day, respectively) were slightly higher than those from SHEDS and ConsExpo (0.74 and 0.55?mg/kg/day, respectively). The ConsExpo derived non-dietary ingestion estimates (99th percentile) under these two scenarios were higher than those from SHEDS, CARES, and Calendex. All models produced extremely low exposure estimates for the flying insect killer scenario. Using similar data inputs, the model estimates by route for these scenarios were consistent and comparable. Most of the models predicted exposures within a factor of 5 at the 50th and 99th percentiles. The differences identified are explained by activity assumptions, input distributions, and exposure algorithms. PMID:22781436

Mitochondria-Dependent Apoptosis of Con A-Activated T Lymphocytes Induced by Asiatic Acid for Preventing Murine Fulminant Hepatitis  

PubMed Central

Selectively facilitating apoptosis of activated T cells is essential for the clearance of pathogenic injurious cells and subsequent efficient resolution of inflammation. However, few chemicals have been reported to trigger apoptosis of activated T cells for the treatment of hepatitis without affecting quiescent T cells. In the present study, we found that asiatic acid, a natural triterpenoid, selectively triggered apoptosis of concanavalin A (Con A)-activated T cells in a mitochondria-dependent manner indicated by the disruption of the mitochondrial transmembrane potential, release of cytochrome c from mitochondria to cytosol, caspases activation, and cleavage of PARP. In addition, asiatic acid also induced the cleavage of caspase 8 and Bid and augmented Fas expression in Con A-activated T cells. However, following activation of T cells from MRLlpr/lpr mice with mutation of Fas demonstrated a similar susceptibility to asiatic acid-induced apoptosis compared with normal T cells, suggesting that Fas-mediated death-receptor apoptotic pathway does not mainly contribute to asiatic acid-induced cell death. Furthermore, asiatic acid significantly alleviated Con A-induced T cell-dependent fulminant hepatitis in mice, as assessed by reduced serum transaminases, pro-inflammatory cytokines, and pathologic parameters. Consistent with the in vitro results, asiatic acid also induced apoptosis of activated CD4+ T cells in vivo. Taken together, our results demonstrated that the ability of asiatic acid to induce apoptosis of activated T cells and its potential use in the treatment of T-cell-mediated inflammatory diseases.

Anti-human IG and B lymphocytes reconstitute the proliferative response to Con A of T lymphocytes depleted of accessory cells  

SciTech Connect

The requirements for the induction of proliferation of human peripheral blood mononuclear cells (PBM) by low concentrations of Concanavalin A (Con A) were studied using /sup 3/H-thymidine incorporation to assay DNA synthesis. Removal of plastic-adherent cells from PBM reduced the proliferative response of lymphocytes to Con A by 80%. Passage of these cells over nylon wool columns totally eliminated their response to Con A. Addition of adherent monocytes or rabbit anti-human IgG conjugated to polyacrylamide beads (anti-IgG beads) to the non-adherent lymphocyte population reconstituted the proliferative response. The lymphoblasts activated in these cultures were more than 90% T11 positive. Anti-IgG beads did not activate lymphocyte proliferation in the absence of Con A. The response of non-adherent lymphocytes to Con A could also be reconstituted by unconjugated rabbit anti-human IgG antiserium. Purified T cells could only be activated by anti-IgG beads and low concentrations of Con A in the presence of irradiated B cells. These results suggest that /sup 3/H-thymidine incorporation by T cells induced by anti-IgG beads and a low concentration of Con A depends on the interaction of anti-IgG and B cells. The authors suggest that B cell produce growth factors for T cells after interacting with anti-IgG.

Calcium balance in haemodialysis--do not lower the dialysate calcium concentration too much (con part).  


The debate on the most adequate dialysate calcium concentration for intermittent haemodialysis therapy is ongoing. There is probably no one optimal concentration. In general, one would like to maintain a neutral calcium balance in adult haemodialysis patients. However, a slightly negative balance may be preferable to avoid soft-tissue calcium accumulation in face of net calcium loss from the bone with ageing. The problem with measurements of calcium balance is that they are generally imprecise, as are estimations of total body calcium and its distribution in various compartments, unless done with labour-intensive methods and great care. The choice of the dialysate calcium will depend on several factors, including parathyroid and vitamin D status, type and severity of concomitant bone disease, presence or absence of arterial calcification, dietary habits, drug treatment and dialysis modality. Ideally the dialysate calcium would be adapted to each patient's needs. This is not feasible, however, in most dialysis settings and neither is it cost-effective. From a practical point of view, a relatively high dialysate calcium concentration in the range of of 1.50-1.75 mmol/L (3.0-3.5 mEq/L) should probably be preferred in haemodialysis patients with high serum PTH levels who are not prescribed calcium-based phosphate binders or high doses of active vitamin D sterols, and in those who are receiving a calcimimetic. In those who are treated with high doses of calcium-based binders and/or active vitamin D derivatives or who have a very low serum PTH level, the optimal dialysate calcium concentration is probably lower, in the range of 1.25-1.50 mmol/L (2.50-3.0 mEq/L). In the present pro/con debate about the optimal dialysate calcium concentration used for the haemodialysis session, we have accepted to defend the viewpoint that a low calcium concentration may do more harm than benefit in many patients. This viewpoint is opposite to that taken by Gotch. He argues that since calcitriol and other active vitamin D derivatives have become available virtually all haemodialysis patients are in positive calcium balance. We would like to take issue with this statement and warn against the indiscriminate use of a low calcium dialysate in all patients receiving haemodialysis therapy. PMID:19666667

Lectin from Canavalia brasiliensis seeds (ConBr) is a valuable biotechnological tool to stimulate the growth of Rhizobium tropici in vitro.  


To study the interactions between a Rhizobium tropici strain and lectins isolated from the seeds of Canavalia ensiformis (ConA) and Canavalia brasiliensis (ConBr), a lectin fluorescence assay was performed. In addition, an experiment was designed to evaluate the effect of the two lectins on bacterial growth. Both lectins were found to bind to R. tropici cells, but the interactions were inhibited by D-mannose. Interestingly, only ConBr stimulated bacterial growth in proportion to the concentrations used (15.6-500 ?g/mL), and the bacterial growth stimulation was inhibited by D-mannose as well. Structure/Function analyses by bioinformatics were carried out to evaluate the volume and carbohydrate recognition domain (CRD) configuration of ConA and ConBr. The difference of spatial arrangement and volume of CRD may indicate the variation between biological activities of both lectins. The results suggest that ConBr could be a promising tool for studies focusing on the interactions between rhizobia and host plants. PMID:22565477

CONS-COCOMAPS: a novel tool to measure and visualize the conservation of inter-residue contacts in multiple docking solutions  

PubMed Central

Background The development of accurate protein-protein docking programs is making this kind of simulations an effective tool to predict the 3D structure and the surface of interaction between the molecular partners in macromolecular complexes. However, correctly scoring multiple docking solutions is still an open problem. As a consequence, the accurate and tedious screening of many docking models is usually required in the analysis step. Methods All the programs under CONS-COCOMAPS have been written in python, taking advantage of python libraries such as SciPy and Matplotlib. CONS-COCOMAPS is freely available as a web tool at the URL: Results Here we presented CONS-COCOMAPS, a novel tool to easily measure and visualize the consensus in multiple docking solutions. CONS-COCOMAPS uses the conservation of inter-residue contacts as an estimate of the similarity between different docking solutions. To visualize the conservation, CONS-COCOMAPS uses intermolecular contact maps. Conclusions The application of CONS-COCOMAPS to test-cases taken from recent CAPRI rounds has shown that it is very efficient in highlighting even a very weak consensus that often is biologically meaningful.



Co-adsorptions of CO/N2O, NO/NH3, CO2/N2 and conversion of CO/N2O to CO2/N2 on ZnO graphene-like nanosheet  

NASA Astrophysics Data System (ADS)

Adsorption energies of CO, CO2, N2O, N2, NO, NH3 and CO/N2O, NO/NH3 and CO2/N2 co-adsorptions on the ZnO graphene-like nanosheet (ZnOGLNS) were obtained using DFT calculations. The energies and thermodynamic properties for conversion of CO + N2O to CO2 + N2 over the ZnOGLNS, its equilibrium constant and adsorption coefficients are reported. The activation energy for the conversion reaction of CO + N2O to CO2 + N2 over the ZnOGLNS of 42.30 kcal/mol was obtained. The CO + N2O to CO2 + N2 conversion over the ZnOGLNS is the energetically and thermodynamically preferred reaction.

[Intracranial hypertension related to sedation with sevoflurane using the AnaConDa(®) device in a patient with severe traumatic brain injury].  


Sedation in neurocritical patients remains a challenge as there is no drug that meets all the requirements. Since the appearance of the AnaConDa(®) device, and according to the latest recommendations, sevoflurane has become an alternative for patients with brain injury. The use of AnaConDa(®) produces an increase in the anatomical dead space that leads to a decrease in alveolar ventilation. If the decrease in the alveolar ventilation is not offset by an increase in minute volume, there will be an increase in PaCO2. We report the case of a patient with severe traumatic brain injury who suffered an increase in intracranial pressure as a result of increased PaCO2 after starting sedation with the AnaConDa(®) device.

Lectin from Canavalia brasiliensis (ConBr) protects hippocampal slices against glutamate neurotoxicity in a manner dependent of PI3K/Akt pathway.  


The excitotoxicity induced by excessive activation of the glutamatergic neurotransmission pathway is involved in several neuropathologies. In this sense, molecules that prevent the release of glutamate or the excessive activation of its receptors can be useful in preventing the neuronal cell death observed in these diseases. Lectins are proteins capable of reversible binding to the carbohydrates in glycoconjugates, and some have been used in the study and purification of glutamate receptors. ConBr is a mannose/glucose-binding lectin purified from Canavalia brasiliensis seeds. In the present study, we aimed to evaluate the neuroprotective activity of ConBr against glutamate-induced excitotoxicity. Hippocampal slices were isolated from adult male mice and incubated for 6h in Krebs saline/DMEM buffer alone (control), in the presence of glutamate or glutamate plus ConBr. The phosphorylation of Akt and mitogen activated protein kinases (MAPKs) such as ERK1/2, p38(MAPK) and JNK1/2/3 was evaluated with western blotting. The results indicate that glutamate provoked a reduction in the hippocampal slice viability (-25%), diminished the phosphorylation of Akt and augmented p38(MAPK) and ERK1 phosphorylation. No changes were observed in the phosphorylation of JNK1/2/3 or ERK2. Notably, ConBr, through a mechanism dependent on carbohydrate interaction, prevented the reduction of cell viability and Akt phosphorylation induced by glutamate. Furthermore, in the presence of the PI3K inhibitor LY294002, ConBr was unable to reverse glutamate neurotoxicity. Taken together, our data suggest that the neuroprotective effect of ConBr against glutamate neurotoxicity requires oligosaccharide interaction and is dependent on the PI3K/Akt pathway. PMID:23454192

Synthesis, growth, structural, spectral, thermal, chemical etching, linear and nonlinear optical and mechanical studies of an organic single crystal 4-chloro 4-nitrostilbene (CONS): a potential NLO material.  


4-Chloro 4-nitrostilbene (CONS) a new organic nonlinear optical material has been synthesized. Employing slow evaporation method, good optical quality single crystals (dimensions up to 6×2×3 mm(3)) have been grown using ethyl methyl ketone (EMK) as a solvent. The grown crystals have been subjected to various characterizations such as single crystal X-ray diffraction, powder XRD, Fourier Transform Infrared spectroscopy (FTIR), proton NMR, solid UV absorption, SHG studies. Single crystal X-ray diffraction reveals that the crystal system belongs to monoclinic with noncentrosymmetric space group P21. The UV-Vis absorption spectrum has been recorded and found that the cut off wavelength is 380 nm. Functional groups and the structure of the title compound have been confirmed by FTIR and (1)H NMR spectroscopic analyses respectively. Molecular mass of the CONS confirmed by the high resolution mass spectral analysis .The thermal behavior of the grown crystal has been studied by TG/DTA analysis and it shows the melting point is at 188.66 °C. Dislocations and growth pattern present in the grown crystal revealed by the etching study. The mechanical strength of the CONS crystal has been studied by Vicker's hardness measurement. The SHG efficiency of the grown crystal has been determined by Kurtz and Perry powder test which revealed that the CONS crystal (327 mV) has 15 times greater efficiency than that of KDP (21.7 mV).

High mobility group box chromosomal protein 1 in acute-on-chronic liver failure patients and mice with ConA-induced acute liver injury.  


High mobility group box chromosomal protein 1 (HMGB1) is an important proinflammatory molecule in many inflammatory disorders, but little is known about its role in acute-on-chronic liver failure (ACLF). Here, we investigated the relationship between the expression of HMGB1 and the disease onset and severity of ACLF patients and mice with acute liver injury/failure induced by concanavalin A (ConA). Peripheral blood mononuclear cells (PBMCs) and serum from ACLF patients were collected, and a mouse model of acute liver injury/failure was induced by ConA. HMGB1 mRNA expression in patient PBMCs or in murine livers and serum HMGB1 protein in ACLF patients and mice were assayed by RT-PCR and Western blotting, respectively. HMGB1 translocation in hepatocytes of ConA-treated mice was assessed by immunohistochemical staining. Up-regulated HMGB1 mRNA levels in PBMCs and accumulated protein in serum were both correlated with disease severity in ACLF patients. In the animal model, HMGB1 levels increased at 4 h and reached its peak value at 8-12 h after challenge with ConA, which suggests that HMGB1 is a relatively late proinflammatory cytokine compared with TNF-?. Translocation of HMGB1 from the nucleus to the cytoplasm in hepatocytes was correlated with the severity of liver injury in mice. While specific anti-HMGB1 antibodies and nicotine protected mice from acute liver injury/failure by reducing mortality and improving liver tissue injury, treatment with recombinant HMGB1 led to an increased mortality due to ConA challenge. Thus, the data from the present study suggest that HMGB1 plays a critical role in the systemic inflammation of ACLF and could be a potential therapeutic target in the treatment of ACLF.

Use of a GnRH vaccine, GonaCon, for prevention and treatment of adrenocortical disease (ACD) in domestic ferrets.  


Adrenocortical disease (ACD) is a common problem in surgically sterilized, middle-aged to old ferrets (Mustela putorius furo). The adrenal tissues of these ferrets develop hyperplasia, adenomas, or adenocarcinomas, which produce steroid hormones including estradiol, 17-hydroxyprogesterone, and androstenedione. Major clinical signs attributable to overproduction of these hormones are alopecia (hair loss) in both sexes and a swollen vulva in females. Pruritus, muscle atrophy, hind limb weakness, and sexual activity or aggression are also observed in both sexes. Males can develop prostatic cysts, prostatitis, and urethral obstruction. ACD is thought to be linked to continuous and increased LH secretion, due to lack of gonadal hormone feedback in neutered ferrets. This continuous elevated LH acts on adrenal cortex LH receptors, resulting in adrenal hyperplasia or adrenal tumor. This study investigated whether the immunocontraceptive vaccine GonaCon, a GnRH vaccine developed to reduce the fertility of wildlife species and the spread of disease, could prevent or delay onset of ACD and treat alopecia in ferrets with existing ACD. Results showed that GonaCon provided relief from ACD by causing production of antibodies to GnRH, probably suppressing production and/or release of LH. Treatment caused many ACD symptoms to disappear, allowing the ferrets to return to a normal life. The study also found that the probability of developing ACD was significantly reduced in ferrets treated with GonaCon when young (1-3 years old) compared to untreated control animals. GonaCon caused injection site reaction in some animals when administered as an intramuscular injection but caused few side effects when administered subcutaneously. Both intramuscular and subcutaneous vaccination resulted in similar levels of GnRH antibody titers. Subcutaneous vaccination with GonaCon is thus recommended to prevent the onset of ACD and as a possible treatment for ACD-signs in domestic ferrets. PMID:23906891

Tissue factor expression in ovarian cancer: implications for immunotherapy with hI-con1, a factor VII-IgGFc chimeric protein targeting tissue factor  

PubMed Central

We evaluated the expression of tissue factor (TF) in ovarian cancer (EOC) and the potential of hI-con1, an antibody-like molecule targeting TF, as a novel form of therapy against chemotherapy-resistant ovarian disease. We studied the expression of TF in 88 EOC by immunohistochemistry (IHC) and real-time-PCR (qRT-PCR) and the levels of membrane-bound-complement-regulatory-proteins CD46, CD55 and CD59 in primary EOC cell lines by flow-cytometry. Sensitivity to hI-con1-dependent-cell-mediated-cytotoxicity (IDCC), complement-dependent-cell-cytotoxicity and inhibition of IDCC by ?-immunoglobulin were evaluated in 5-h 51chromium-release-assays. Cytoplasmic and/or membrane TF expression was observed in 24 out of 25 (96%) of the EOC samples tested by IHC, but not in normal ovarian-tissue. EOC with clear cell histology significantly overexpress TF when compared to serous, endometrioid, or undifferentiated tumors by qRT-PCR. With a single exception, all primary EOC that overexpressed TF demonstrated high levels of CD46, CD55 and CD59 and regardless of their histology or resistance to chemotherapy, were highly sensitive to IDCC. The effect of complement and physiologic doses of ?-immunoglobulin on IDCC in ovarian cancer cell lines overexpressing TF was tumor specific and related to the overexpression of CD59 on tumor cells. Small-interfering-RNA-mediated knockdown of CD59 expression in ovarian tumors significantly increased hI-con1-mediated cytotoxic activity in vitro. Finally, low doses of interleukin-2 further increased the cytotoxic effect induced by hI-con1 (P < 0.01). hI-con1 molecule induces strong cytotoxicity against primary chemotherapy-resistant ovarian cancer cell lines overexpressing TF and may represent a novel therapeutic agent for the treatment of ovarian tumors refractory to standard treatment modalities.

Virgin Caenorhabditis remanei females are attracted to a coital pheromone released by con-specific copulating males  

PubMed Central

The gonochoristic soil nematode Caenorhabditis remanei strictly requires copulation for species propagation. Males of this species are sexually promiscuous with females of other species; therefore, we asked in this study whether virgin C. remanei females display evidence of mate choice. We digitally recorded and measured the locomotor behaviors of one or more virgin females in the presence of a single male on a 5 mm diameter mating lawn. We observed that initially only the male modifies his locomotor trajectory to another animal on the mating lawn; the virgin females showed no locomotor bias toward the mate-searching male. However, once a male started to copulate, females in the vicinity altered their movement trajectories toward the copulating couple. Newly inseminated females are refractive to the coital signal, but partially regain their attraction to copulating males after 24 h. We found only copulating males with an intact gonad can attract females, and that the coital signal can be broadcasted at least 1.5 mm through the air. Unlike males, which are also attracted to hetero-specific females, virgin C. remanei females will only crawl toward a copulating con-specific male. We suggest that Caenorhabditis females use the coital signal as a pheromone to identify a vigorous male of their own species.

Document-level classification of CT pulmonary angiography reports based on an extension of the ConText algorithm.  


In this paper we describe an application called peFinder for document-level classification of CT pulmonary angiography reports. peFinder is based on a generalized version of the ConText algorithm, a simple text processing algorithm for identifying features in clinical report documents. peFinder was used to answer questions about the disease state (pulmonary emboli present or absent), the certainty state of the diagnosis (uncertainty present or absent), the temporal state of an identified pulmonary embolus (acute or chronic), and the technical quality state of the exam (diagnostic or not diagnostic). Gold standard answers for each question were determined from the consensus classifications of three human annotators. peFinder results were compared to naive Bayes' classifiers using unigrams and bigrams. The sensitivities (and positive predictive values) for peFinder were 0.98(0.83), 0.86(0.96), 0.94(0.93), and 0.60(0.90) for disease state, quality state, certainty state, and temporal state respectively, compared to 0.68(0.77), 0.67(0.87), 0.62(0.82), and 0.04(0.25) for the naive Bayes' classifier using unigrams, and 0.75(0.79), 0.52(0.69), 0.59(0.84), and 0.04(0.25) for the naive Bayes' classifier using bigrams.

Status and Progress of a Fault Current Limiting Hts Cable to BE Installed in the con EDISON Grid  

NASA Astrophysics Data System (ADS)

In the last decade, significant advances in the performance of second generation (2G) high temperature superconducting wire have made it suitable for commercially viable applications such as electric power cables and fault current limiters. Currently, the U.S. Department of Homeland Security is co-funding the design, development and demonstration of an inherently fault current limiting HTS cable under the Hydra project with American Superconductor and Consolidated Edison. The cable will be approximately 300 m long and is being designed to carry 96 MVA at a distribution level voltage of 13.8 kV. The underground cable will be installed and energized in New York City. The project is led by American Superconductor teamed with Con Edison, Ultera (Southwire and nkt cables joint venture), and Air Liquide. This paper describes the general goals, design criteria, status and progress of the project. Fault current limiting has already been demonstrated in 3 m prototype cables, and test results on a 25 m three-phase cable will be presented. An overview of the concept of a fault current limiting cable and the system advantages of this unique type of cable will be described.

Pro/con clinical debate: The use of prone positioning in the management of patients with acute respiratory distress syndrome  

PubMed Central

Critical care medicine is a relatively new specialty and as such there is not a great deal of accumulated data to allow clinicians to practice 'evidence-based medicine' in all situations they encounter. When evidence does exist, intensivists may choose not to follow it based on 'gut feelings' or their own interpretation of how the data apply to their patient. It is perhaps not surprising that these latter events occur given that intensivists are often literally fighting for their patient's lives. Prone positioning evokes a large emotional response from many intensivists. Despite accumulating data there appears to be two camps of clinicians: those who strongly believe in the therapy, and those who want more data. The emotion and rationale for the mindset of the two camps is evident in this issue of Critical Care Forum. With compelling arguments on both sides of the fence, it is apparent that this debate is far from over. The authors of this pro/con debate, which is based on a clinical scenario, first describe their position and then respond to their opponent's position.

Laboratory simulation of Kuiper belt object volatile ices under ionizing radiation: CO-N2 ices as a case study.  


The exposure of icy Kuiper belt objects (KBOs) by ionizing radiation was simulated in this case of exposing carbon monoxide-nitrogen (CO-N(2)) ices by energetic electrons. The radiation-induced chemical processing was monitored on-line and in situ via FTIR spectroscopy and quadrupole mass spectrometry. Besides the array of carbon oxides being reproduced as in neat irradiated carbon monoxide (CO) ices studied previously, the radiation exposure at 10 K resulted in the formation of nitrogen-bearing species of isocyanato radical (OCN), linear (l-NCN), nitric oxide (NO), nitrogen dioxide (NO(2)), plus diazirinone (N(2)CO). The infrared assignments of these species were further confirmed by isotopic shifts. The temporal evolution of individual species was found to fit in first-order reaction schemes, prepping up the underlying non-equilibrium chemistry on the formation of OCN, l-NCN, and NO radicals in particular. Also unique to the binary KBO model ices and viable for the future remote detection is diazirinone (N(2)CO) at 1860 cm(-1) (2?(5)) formed at lower radiation exposure. PMID:21687881

The Protective Effect of Intrasplenic Transplantation of Ad-IL-18BP/IL-4 Gene-Modified Fetal Hepatocytes on ConA-Induced Hepatitis in Mice  

PubMed Central

Background Concanavalin A (ConA)-induced hepatitis is an experimental murine model mirroring the pathology of human autoimmune hepatitis. Aim To investigate the effects of intrasplenically transplanted fetal hepatocytes (BNL.CL2) transfected with recombinant adenovirus vector expressing the IL-18 binding protein (IL-18BP) and IL-4 fusion protein on ConA-induced hepatitis in mice. Methods Ad-IL-18BP/IL-4 was used to infect BNL.CL2 cells. IL-4 and IL-18BP fusion protein expression were detected by ELISA and Western blotting. BNL.CL2 cells infected with Ad-IL-18BP/IL-4 were intrasplenically transplanted into mice. After 10 days, mice were injected with ConA (15 mg/kg), and sacrificed 18 hours later. Liver injury was assessed by serum transaminase and liver histology. TNF-?, IL-18, IL-4, IL-10, IL-12p70 and monocyte-chemoattracting protein (MCP)-1 levels in serum and liver homogenates were detected by ELISA. Signaling molecules in liver homogenates were analyzed by Western blotting. Results Ad-IL-18BP/IL-4 effectively expressed the IL-18BP/IL-4 fusion protein for more than 14 days in BNL.CL12 cells. Treatment of mice with Ad-IL-18BP/IL-4-BNL.CL2 before ConA injection significantly reduced the elevated plasma levels of transaminases compared with ConA control groups. TNF-?, IL-18, IL-12p70 and MCP-1 levels in serum and liver homogenates from mice transplanted with Ad-IL-18BP/IL-4-BNL.CL2 were lower and IL-4 and IL-10 levels were higher than control groups. Phosphorylation levels of NF-?B p65, AKT, p38 and JNK1/2 in liver homogenates were markedly suppressed by Ad-IL-18BP/IL-4. Conclusions Ad-IL-18BP/IL-4 was effectively transfected into mouse BNL.CL2 cells. Intrasplenic transplantation of Ad-IL-18BP/IL-4-BNL.CL12 cells alleviated the severity of inflammation in ConA-induced experimental hepatitis and provides a useful basis for the targeted gene therapy of liver disease.

Nonsurgical fertility control that could be administered to feral cats in the field would be a powerful tool for cat population control. The objective was to test the efficacy and duration of activity of a single-dose GnRH immunocontraceptive vaccine (GonaCon™) on the fertility of adult female laboratory cats. Vaccinated cats (n = 15) received a single injection of vaccine containing a GnRH-KLH conjugate (200 ?g) emulsified in a mycobacterial and oil adjuvant on study Day 0. Sham-treated cats (n = 5) received a single injection containing all vaccine components except the GnRH-KLH conjugate. A breeding trial started on study Day 120. Vaccinated cats had a longer time to conception (median 39.7 mo) compared to sham-treated cats (4.4 mo; P < 0.001). A total of 93% of vaccinated cats remained infertile for the first year following vaccination, whereas 73, 53, and 40% were infertile for 2, 3, and 4 y, respectively. At study termination (5 y after a single GnRH vaccine was administered), four cats (27%) remained infertile. The GnRH antibody titers declined more rapidly in short-term responding cats with < 2 y of infertility (n = 4), compared to long-term responding cats that experienced fertility control for >2 y (n = 11) (P < 0.05). Non-painful but persistent late-onset granulomatous injection site masses appeared 2 y after initial vaccination in five cats. We concluded that GnRH immunocontraception is an ideal candidate for further development for feral cat control. PMID:21835455

Preliminary experience with a 'sub-50' combined oral contraceptive, containing 35 micrograms ethinyl oestradiol and 1 mg norethisterone ('NeoCon').  


The present trend in oral contraception is clearly in favour of the 'sub-50' pills, taking into consideration the recent publications on the association between cardiovascular affections and pill intake. 'NeoCon', a combination pill containing 1 mg norethisterone and 35 micrograms ethinyl oestradiol, has been investigated in the United States, Mexico, Germany, Belgium and the United Kingdom. From all these studies, it could be concluded that it is an effective and well-tolerated oral contraceptive. From the present series, totalling 104 patients with 1232 cycles, first clinical impressions confirm the evaluations of other investigators: no pregnancies, only mild cycle disturbances disappearing after a few adaptation cycles, few side-effects and excellent tolerance. Due to the low potency and the low contents of its components, it is suggested that 'NeoCon' is appropriate for all women in general and for the younger women in particular. PMID:7433480

A review of the practice of sedation with inhalational anaesthetics in the intensive care unit with the AnaConDa(®) device.  


The intensive care unit (ICU) environment is often perceived to be hostile and frightening by patients due to unfamiliar surroundings coupled with presence of numerous personnel, monitors and other equipments as well as a loss of perception of time. Mechanical ventilation and multiple painful procedures that often need to be carried out in these critically ill patients add to their overall anxiety. Sedation is therefore required not only to allay the stress and anxiety, but also to allow for mechanical ventilation and other invasive therapeutic and diagnostic procedures to be performed. The conventional intravenous sedative agents used in ICUs suffer from problems of over sedation, tachyphylaxis, drug accumulation, organ specific elimination and often lead to patient agitation on withdrawal. All this tend to prolong the ventilatory as well as ICU and hospital discharge time, which increase the risk for infection and add to the overall increase in morbidity, mortality and hospital costs. In 2005, the anaesthetic conserving device (AnaConDa(®)) was marketed for ICU sedation with volatile anaesthetic agents. A number of trials have shown the effectiveness of using volatile anaesthetic agents for ICU sedation with the AnaConDa device. Compared with intravenous sedatives, use of volatile anaesthetic agents have resulted in shorter wake up and extubation time, lesser duration of mechanical ventilation and faster discharge from hospitals. This review shall focus on the benefits, technical pre-requisites and status of sedation with volatile anaesthetic agents in ICUs with the AnaConDa(®) device. PMID:23325934

The role of RNA editing of the serotonin 2C receptor in a rat model of oro-facial neuropathic pain.  


We examined whether infraorbital nerve injury affected the RNA editing efficiency of the serotonin (5HT) 2C receptor in the cervical spinal cord, in association with increased pain thresholds, and whether a 5HT reuptake inhibitor (fluvoxamine; Depromel, Meiji Seika, Tokyo, Japan) altered this editing. Accordingly, we injured rats with an infraorbital nerve loose ligation and examined the pain thresholds, mRNA and mRNA editing of the 5HT2C receptor. We evaluated changes in mRNA editing and 5HT2C mRNA expression using cloning along with sequence analysis and quantitative reverse transcription-polymerase chain reaction to compare samples taken at post-injury day 28 from spinal cord sites, including the trigeminal nucleus caudalis, in naive, sham and injured rats (groups of each type had also received fluvoxamine). 5HT2C receptor expression was maintained post-injury. The RNA editing efficiency was statistically significantly lower at molecular sites A and B in ipsilateral spinal cord samples from injured rats than in bilateral samples from naive and sham rats, and in contralateral samples from injured rats. After injury, the proportional presence of two receptor isoforms changed, i.e. statistically significantly less VNV and significantly more INV and ISV. The proportions reverted after fluvoxamine administration. The post-injury change might be evidence of a functional adaptation mechanism that increases the expression of 5HT2C mRNA isoforms that encode receptors that are more sensitive to 5HT. This would activate the brainstem-spinal descending 5HT systems and, in effect, suppress nociceptive signals from primary afferent neurons to the spinal trigeminal nucleus caudalis. PMID:18445227

[Oro-facial manifestations during AIDS/HIV infection. Apropos of 60 cases seen at the Ambulatory Treatment Center in Ouagadougou and at the Yalgado University Hospital Center].  


The opportinistics complaints of the AIDS occur all along the episode of the infection and depend on the individual's body immunity and on the existence or no of an anti-retroviral treatment. The buccal appearences on the face are relatively frequent. They are dominated by the buccal mycosis, the lymphatic ganglion's complaints, the inflammation of gums and buccal mucous, and the tooth decay in our context. Some authors suggest a classification that can make easy their study and treatment. Complaints like the herpes simplex infection, the herpes zoster infection, are usually found during the symptomatic stage non AIDS, whereas others like KAPOSI's disease are typical to AIDS disease. The availlability of an anti-retroviral treatment and a specialized one strenghten the efficiency of the reimbursement and improve the prognosis. PMID:16910114

Hazardous and mixed waste generation at the DOE/ORO installations operated by Martin Marietta Energy Systems, Inc. , during calendar years 1987 and 1988  

SciTech Connect

A program was known as the Hazardous Waste Development, Demonstration, and Disposal (HAZWDDD) Program and was formed to address several waste management issues with the main objective being to ensure that all Martin Marietta Energy Systems, Inc., (Energy Systems) treatment, storage, and disposal (TSD) needs for hazardous and mixed waste were identified and planned for properly. A data base was developed and maintained which contained information concerning all hazardous and mixed waste generated, stored, treated, and/or disposed at the five Energy Systems instal-lations during CY 1987. This document presents an update of the HAZWDDD data base for CY 1988. Summaries and figures concerning the data are presented in the body of the report, and a breakdown of the individual waste streams is presented in Appendix A. All five installations produce purely hazardous and mixed waste. The gaseous diffusion plants and Y-12 produce mixed waste contaminated primarily with uranium isotopes, while the mixed waste generated at Oak Ridge National Laboratory (ORNL) is contaminated with various radioisotopes. Generation rates of both hazardous and mixed waste are reported, and inventories of mixed waste are discussed. 18 refs., 9 figs., 5 tabs.

Los procesos de fotoionización son de una importancia fundamental [1] y encuentran aplicación en un gran número de contextos científicos: Astrofísica [2], química de las radiaciones, biología. Los investigadores de dichos campos, necesitan de valores de fiables de secciones eficaces para la fotoionización parcial, la Fotoabsorción, así como para los procesos de fotofragmentación en amplios intervalos espectrales, particularmente en estudios de modelización [3-5]. En este trabajo se ha centrado la atención sobre el oxido nítrico, que se ha considerado apropiado y relevante por varios motivos: por el trascendental papel que representa en la física y química de la alta atmosfera [6], aparte de por estar íntimamente relacionado con los problemas de contaminación. Los procesos de recombinación disociativa [7] del NO, donde los estados Rydberg se encuentran directamente implicados, son relevantes, por ejemplo, en las regiones E y F de la ionosfera [7]. En este trabajo se estudia la fotoionización del NO desde el estado fundamental con la versión molecular del método del orbital de defecto cuántico (MQDO). Para ello se calcula el diferencial de las fuerzas de oscilador parciales que constituyen los canales de fotoionización del NO desde el estado fundamental. La continuidad del diferencial de fuerza de oscilador calculada a través del umbral de fotoionización, esto es, en las regiones del espectro discreta y del continua, se adopta como criterio de calidad la escasez de datos comparativos [8].

Induction of Macrophage Migration Inhibitory Factor in ConA-Stimulated Rheumatoid Arthritis Synovial Fibroblasts through the P38 MAP Kinase-Dependent Signaling Pathway  

PubMed Central

Background/Aims This study was undertaken to identify the intracellular signaling pathway involved in induction of macrophage migration inhibitory factor (MIF) in human rheumatoid arthritis (RA) synovial fibroblasts. Methods Human RA synovial fibroblasts were treated with concanavalin A (ConA), various cytokines, and inhibitors of signal transduction molecules. The production of MIF by synovial fibroblasts was measured in culture supernatants by ELISA. The expression of MIF mRNA was determined using reverse transcriptase polymerase chain reaction (RT-PCR) and real-time PCR. Phosphorylation of p38 mitogen-activated protein (MAP) kinase in synovial fibroblasts was confirmed using Western blotting. The expression of MIF and p38 MAP kinase in RA synovium was determined using dual immunohistochemistry. Results The production of MIF by RA synovial fibroblasts increased in a dose-dependent manner after ConA stimulation. MIF was also induced by interferon-?, CD40 ligand, interleukin-15, interleukin-1?, tumor necrosis factor-?, and transforming growth factor-?. The production of MIF by RA synovial fibroblasts was significantly reduced after inhibition of p38 MAP kinase. The expression of MIF and p38 MAP kinase was upregulated in the RA synovium compared with the osteoarthritis synovium. Conclusions These results suggest that MIF production was induced through a p38 MAP-kinase-dependent pathway in RA synovial fibroblasts.

The International Consortium on Lithium Genetics (ConLiGen): An Initiative by the NIMH and IGSLI to Study the Genetic Basis of Response to Lithium Treatment  

PubMed Central

For more than half a decade, lithium has been successfully used to treat bipolar disorder. Worldwide, it is considered the first-line mood stabilizer. Apart from its proven antimanic and prophylactic effects, considerable evidence also suggests an antisuicidal effect in affective disorders. Lithium is also effectively used to augment antidepressant drugs in the treatment of refractory major depressive episodes and prevent relapses in recurrent unipolar depression. In contrast to many psychiatric drugs, lithium has outlasted various pharmacotherapeutic ‘fashions’, and remains an indispensable element in contemporary psychopharmacology. Nevertheless, data from pharmacogenetic studies of lithium are comparatively sparse, and these studies are generally characterized by small sample sizes and varying definitions of response. Here, we present an international effort to elucidate the genetic underpinnings of lithium response in bipolar disorder. Following an initiative by the International Group for the Study of Lithium-Treated Patients ( and the Unit on the Genetic Basis of Mood and Anxiety Disorders at the National Institute of Mental Health, lithium researchers from around the world have formed the Consortium on Lithium Genetics ( to establish the largest sample to date for genome-wide studies of lithium response in bipolar disorder, currently comprising more than 1,200 patients characterized for response to lithium treatment. A stringent phenotype definition of response is one of the hallmarks of this collaboration. ConLiGen invites all lithium researchers to join its efforts.

A wireless, remote-query and high sensitivity Escherichia coli O157: H7 biosensor based on the recognition action of Con A  

PubMed Central

Escherichia coli O157: H7 is detected using a remote-query (wireless, passive) magnetoelastic sensor platform to which a 1 µm-thick layer of Bayhydrol 110 and then a layer of functionalized mannose is applied. The multivalent binding of lectin concanavalin A (Con A) to the E. coli surface O-antigen and mannose favors the strong adhesion of E. coli to the mannose modified magnetoelastic sensor; E. coli is rigidly and strongly attached on the mannose-modified sensor through Con A, which works as a bridge to bind to the E. coli surface O-antigen and mannose modified sensor surface. As E. coli is bound to the sensor its resonance frequency shifts, enabling quantification of E. coli concentration with a limit of detection of 60 cells/mL and a linear logarithmic response range of 6.0×101 to 6.1×109 cells/mL. The analysis can be directly conducted without incubation, and completed in 3 h or less.

The Effect of Coadsorbed Water on the Stability, Con?guration and Interconversion of Formyl (HCO) and Hydroxymethylidyne (COH) on Platinum (1 1 1)  

SciTech Connect

Two forms of the methanol electro-oxidation intermediate with stoichiometry C:H:O, COH (hydroxymethylidyne) and HCO (formyl), on Pt (11 1) with and without coadsorbed water were studied using density functional theory calculations. The structure, adsorption energy and stability with respect to dissociation were calculated. Both HC=O and C–OH were stable on clean Pt (11 1) and with a single coadsorbed water molecule, while only the HCO con?guration was stable in the presence of a whole water layer. The vibrational modes of HC=O on a bridge site showed no mode around 1700 cm-1 characteristic of C=O stretch making it hard to distinguish it from C–OH.

Broadening, shifting, and line asymmetries in the 2<--0 band of CO and CO-N2: Experimental results and theoretical calculations  

NASA Astrophysics Data System (ADS)

We have measured the room temperature, widths, pressure shifts, and line asymmetry coefficients for many transitions of the first overtone band of CO and CO perturbed by N2. The broadening coefficients were obtained with an accuracy of about 1%. The pure CO profiles have been fitted by a Voigt profile while the CO-N2 spectral profiles have been fitted with a Lorentz and an empirical line shape model (HCv) that blends together a hard collision model and a speed-dependent Lorentz profile. In addition to the Voigt, Lorentz, and HCv models, we have added a dispersion profile to account for weak line mixing. The line broadening and shift coefficients are compared to semiclassical calculations employing a variety of intermolecular interactions. The line asymmetry results are compared to line mixing calculations based on the energy corrected sudden (ECS) model. The results indicate that effects other than line mixing also contribute to the measured line asymmetry.

Hydrogen adsorption and magnetic behavior of Fen and Con clusters: Controlling the magnetic moment and anisotropy one atom at a time  

NASA Astrophysics Data System (ADS)

Theoretical studies to investigate the effect of H absorption on the magnetic moment of small Fen and Con clusters have been carried out using gradient corrected density-functional approach. Our studies on clusters containing up to four transition metal and 2 H atoms show that the successive addition of H atoms can lead to monotonic or oscillatory change from the free cluster magnetic moment. A detailed analysis of the density of electronic states shows that the variations in the magnetic moment can be related to the location of the lowest unoccupied molecular orbital in the parent cluster. It is shown that the addition of hydrogen can substantially change the magnetic anisotropy. In particular Co3H2 is shown to exhibit magnetic anisotropy that is higher than any of the known anisotropies in the molecular nanomagnets.

Intracellular free zinc up-regulates IFN-? and T-bet essential for Th1 differentiation in Con-A stimulated HUT-78 cells  

PubMed Central

Zinc deficiency impairs cellular immunity. Up-regulation of mRNA levels of IFN-?, IL-12R?2, and T-bet are essential for Th1 differentiation. We hypothesized that zinc increases Th1 differentiation via up-regulation of IFN-? and T-bet expression. To test this hypothesis, we used zinc-deficient and zinc-sufficient HUT-78 cells (a Th0 cell line) under different condition of stimulation in this study. We also used TPEN, a zinc-specific chelator, to decrease the bioavailability of zinc in the cells. We measured intracellular free zinc, cytokines, and the mRNAs of T-bet, IFN-?, and IL-12R?2. In this study, we show that in zinc-sufficient HUT-78 cells (a Th0 cell line), mRNA levels of IFN-?, IL-12R?2, and T-bet in PMA/PHA-stimulated cells were increased in comparison to zinc-deficient cells. Although intracellular free zinc was increased slightly in PMA/PHA-stimulated cells, Con-A-stimulated cells in 5 ?M zinc medium showed a greater sustained increase in intracellular free zinc in comparison to cells incubated in 1 ?M zinc. The cells pre-incubated with TPEN showed decreased mRNA levels of IFN-? and T-bet mRNAs in comparison to cells without TPEN incubation. We conclude that stimulation of cells by Con-A via TCR, release intracellular free zinc which functions as a signal molecule for generation of IFN-? and T-bet, and IL-12Rb?2 mRNAs required for Th1 cell differentiation. These results suggest that zinc increase Th1 cell differentiation by up-regulation of IFN-? and T-bet, and IL-12Rb?2 mRNAs.

A novel mammalian myosin I from rat with an SH3 domain localizes to Con A-inducible, F-actin-rich structures at cell-cell contacts  

PubMed Central

In an effort to determine diversity and function of mammalian myosin I molecules, we report here the cloning and characterization of myr 3 (third unconventional myosin from rat), a novel mammalian myosin I from rat tissues that is related to myosin I molecules from protozoa. Like the protozoan myosin I molecules, myr 3 consists of a myosin head domain, a single light chain binding motif, and a tail region that includes a COOH-terminal SH3 domain. However, myr 3 lacks the regulatory phosphorylation site present in the head domain of protozoan myosin I molecules. Evidence was obtained that the COOH terminus of the tail domain is involved in regulating F-actin binding activity of the NH2-terminal head domain. The light chain of myr 3 was identified as the Ca(2+)-binding protein calmodulin. Northern blot and immunoblot analyses revealed that myr 3 is expressed in many tissues and cell lines. Immunofluorescence studies with anti-myr 3 antibodies in NRK cells demonstrated that myr 3 is localized in the cytoplasm and in elongated structures at regions of cell-cell contact. These elongated structures contained F-actin and alpha-actinin but were devoid of vinculin. Incubation of NRK cells with Con A stimulated the formation of myr 3-containing structures along cell-cell contacts. These results suggest for myr 3 a function mediated by cell-cell contact.



Observations on the effects of inhaled isoflurane in long-term sedation of critically Ill children using a modified AnaConDa©-system.  


Long-term intravenous sedation may present problems due to dependence and side effects. Medical records of children who were administered isoflurane were reviewed. 15 patients (9 boys, 6 girls) with a mean age of 11.8 month (+2.4) were analysed.Analgesia and sedation was given in mean 9.7+1.1 days before commencing inhalation using a modified application device (AnaConDa©). Administration was given over a period of 7.2+1.4 days. Depth of sedation was monitored by using Comfort- and Hartwig-scores. Observations included continuous monitoring of heart-rate, pulse oxymetry, blood pressure and cerebral tissue oxygenation.Within 4 h post administration of isoflurane a satisfactory increase in the depth of sedation was seen and kept till extubation. 6/15 patients received tracheostomies during the observation period. None of the patients observed suffered life-critical events of the modified application of isoflurane proceeded without complications. Ketamine and clonidine infusion rates were significantly reduced (p<0.005) as well as the use and overall infusion rate of midazolam, ?-hydroxy butyrate, fentanyl and morphine (p<0.05).Isoflurane inhalation may provide an additional option for long-term sedation in a specific group of critically ill infants but neurodegenerative toxic effects will have to be taken into account when using volatile anesthetics at any time during infancy.

Comparison between dynamic cystocolpoproctography and dynamic pelvic floor MRI: pros and cons: Which is the "functional" examination for anorectal and pelvic floor dysfunction?  


"Functional" imaging of anorectal and pelvic floor dysfunction has assumed an important role in the diagnosis and management of these disorders. Although defecography has been widely practiced for decades to evaluate the dynamics of rectal emptying, debate concerning its clinical relevance, how it should be done and interpreted continues. Due to the recognition of the association of defecatory disorders with pelvic organ prolapse in women, the need to evaluate the pelvic floor as a unit has arisen. To meet this need, defecography has been extended to include not only evaluation of defecation disorders but also the rest of the pelvic floor by opacifying the small bowel, vagina, and the urinary bladder. The term "dynamic cystocolpoproctography" (DCP) has been appropriately applied to this examination. Rectal emptying performed with DCP provides the maximum stress to the pelvic floor resulting in complete levator ani relaxation. In addition to diagnosing defecatory disorders, this method of examination demonstrates maximum pelvic organ descent and provides organ-specific quantification of organ prolapse, information that is only inferred by means of physical examination. It has been found to be of clinical value in patients with defecation disorders and the diagnosis of associated prolapse in other compartments that are frequently unrecognized by history taking and the limitations of physical examination. Pelvic floor anatomy is complex and DCP does not show the anatomical details pelvic magnetic resonance imaging (MRI) provides. Technical advances allowing acquisition of dynamic rapid MRI sequences has been applied to pelvic floor imaging. Early reports have shown that pelvic MRI may be a useful tool in pre-operative planning of these disorders and may lead to a change in surgical therapy. Predictions of hypothetical increase cancer incidence and deaths in patients exposed to radiation, the emergence of pelvic floor MRI in addition to questions relating to the clinical significance of DCP findings have added to these controversies. This review analyses the pros and cons between DCP and dynamic pelvic floor MRI, addresses imaging and interpretive controversies, and their relevance to clinical management. PMID:22446896

Do not disturb the animals! or, how Con Edison saved $300,000 using a trenchless technology to renew 3,000 feet of leaking gas main at the Bronx Zoo  

SciTech Connect

Every leaking gas main presents a challenge. But when that leaking main follows a series of sweeping bends on its route through North America`s largest urban wildlife park, it presents a special challenge. That was the situation Consolidated Edison Company of New York Inc. recently faced when numerous leaks were discovered along 3,000 feet of a 95-year-old, 12-inch cast-iron main that winds through New York City`s Bronx Zoo. Con Edison knew it needed a long-term solution to this increasingly common problem. Thanks to the cooperative efforts of the utility`s operations and research departments and the Gas Research Institute (GRI), Con Edison also knew about a trenchless technology that could renew the pipe with minimal impact to the environment--while saving the utility a substantial sum of money in the process. In the Paltem system, a woven polyester hose is injected with an epoxy resin and then inverted (turned inside out) into a pipe at an access pit. The liner then bonds to the inside wall of the pipe, forming a smooth, flexible and pressure-resistant lining. The process is environmentally safe, requires very little excavation and can be installed in days, rather than the weeks or months it can take to dig up and replace existing pipe.

Signals provided in vivo by human rIL-2 and Con A can switch hapten-specific tolerance from unresponsiveness to responsiveness in the South African clawed toad.  

PubMed Central

Injection in vivo of trinitrobenzene sulphonic acid (TNBS) will conjugate trinitrophenyl (TNP) to the cells and proteins of rodents, and induce hapten-specific tolerance to this epitope. However, the induction of hapten-specific tolerance by this method in the South African clawed toad, Xenopus laevis, is restricted to its subsequent presentation on Ficoll or polyvinylpyrrolidone (PVP). This restricted tolerance depends on the stimulation of an N-methyl-N-nitrosourea (NMU)-insensitive, cyclophosphamide (CyP)-sensitive hapten-specific (suppressor) population that is functionally demonstrable in vitro. Unresponsiveness to TNP-Ficoll can be switched to responsiveness by injection in vivo of recombinant DNA-produced human IL-2 (rIL-2) or the plant-derived lectin, concanavalin A (Con A). Responsiveness to TNP-Ficoll requires thymic presence, although thymic extracts from rIL-2- or Con A-injected toads will suffice. Unresponsiveness to TNP-PVP can also be broken by these reagents, but thymic presence is not required with this immunogen. TNP-Ficoll responses are thymus requiring, while those to TNP-PVP are not, in the toad. Since TNBS failed to stimulate hapten-specific tolerance to a secondary challenge to TNP-Ficoll, we suggest that the suppressor function involved in the establishment of the unresponsive state may act on the differentiation, rather than on the function, of the relevant B cells.

Distribution of immune cells in head and neck cancer: CD8+ T-cells and CD20+ B-cells in metastatic lymph nodes are associated with favourable outcome in patients with oro- and hypopharyngeal carcinoma  

PubMed Central

Background Tumour infiltrating lymphocytes (TIL) are generally considered to represent a host immune response directed against tumour antigens. TIL are also increasingly recognised as possible prognostic parameters. However, the effects observed are variable indicating that results cannot be extrapolated from type of tumour to another. Moreover, it has been suggested that primary solid tumours may be ignored by the immune system and that a meaningful immune response is only mounted in regional lymph nodes. Methods We have examined the local distribution of immune cells in tumour-related compartments in head and neck squamous cell carcinomas (HNSCC). In a second step, the prognostic impact of these cells on disease-free survival (DFS) was analysed. A total of 198 tissue cores from 33 patients were evaluated using tissue mircroarray technique and immunohistochemistry. Tumour-infiltrating immune cells were identified using antibodies specific for CD3, CD8, GranzymeB, FoxP3, CD20 and CD68 and quantified using an image analysis system. Results We demonstrate a relative expansion of FoxP3+ regulatory T-cells (Treg) and of cytotoxic T-cells among tumour infitrating T-cells. We also show that intratumoural CD20+ B-cells are significantly more frequent in metastatic deposits than in primary tumours. Furthermore, we observed a reduced number of peritumoural CD8+ T-cells in metastatic lymph nodes as compared to univolved regional nodes suggesting a local down-modulation of cellular immunity. All other immune cells did not show significant alterations in distribution. We did not observe an association of tumour infiltrating immune cells at the primary site with outcome. However, increased numbers of intraepithelial CD8+ TIL in metastatic tumours as well as large numbers of peritumoural B-cells in lymph node metastases were associated with favourable outcome. Unexpectedly, no effect on patient outcome was observed for Treg in any compartment. Conclusion Our results suggest that alterations in lymphocyte distribution in regional lymph nodes rather than at the primary tumour site may be relevant for patient prognosis. Moreover, we demonstrate that in addition to cellular immunity humoral immune responses may be clinically relevant in anti-tumour immunity.

Phase II study of induction chemotherapy with TPF followed by radioimmunotherapy with Cetuximab and intensity-modulated radiotherapy (IMRT) in combination with a carbon ion boost for locally advanced tumours of the oro-, hypopharynx and larynx - TPF-C-HIT  

PubMed Central

Background Long-term locoregional control in locally advanced squamous cell carcinoma of the head and neck (SCCHN) remains challenging. While recent years have seen various approaches to improve outcome by intensification of treatment schedules through introduction of novel induction and combination chemotherapy regimen and altered fractionation regimen, patient tolerance to higher treatment intensities is limited by accompanying side-effects. Combined radioimmunotherapy with cetuximab as well as modern radiotherapy techniques such as intensity-modulated radiotherapy (IMRT) and carbon ion therapy (C12) are able to limit toxicity while maintaining treatment effects. In order to achieve maximum efficacy with yet acceptable toxicity, this sequential phase II trial combines induction chemotherapy with docetaxel, cisplatin, and 5-FU (TPF) followed by radioimmunotherapy with cetuximab as IMRT plus carbon ion boost. We expect this approach to result in increased cure rates with yet manageable accompanying toxicity. Methods/design The TPF-C-HIT trial is a prospective, mono-centric, open-label, non-randomized phase II trial evaluating efficacy and toxicity of the combined treatment with IMRT/carbon ion boost and weekly cetuximab in 50 patients with histologically proven locally advanced SCCHN following TPF induction chemotherapy. Patients receive 24 GyE carbon ions (8 fractions) and 50 Gy IMRT (2.0 Gy/fraction) in combination with weekly cetuximab throughout radiotherapy. Primary endpoint is locoregional control at 12 months, secondary endpoints are disease-free survival, progression-free survival, overall survival, acute and late radiation effects as well as any adverse events of the treatment as well as quality of life (QoL) analyses. Discussion The primary objective of TPF-C-HIT is to evaluate efficacy and toxicity of cetuximab in combination with combined IMRT/carbon ion therapy following TPF induction in locally advanced SCCHN.

Oroshigane, a New Segment Polarity Gene of Drosophila Melanogaster, Functions in Hedgehog Signal Transduction  

PubMed Central

Here we describe a new segment polarity gene of Drosophila melanogaster, oroshigane (oro). Identified as a dominant enhancer of Bar (B), oro is also recessive embryonic lethal, and homozygous oro embryos show variable substitution of naked cuticle with denticles. These patterns are distinctly similar to those of hedgehog (hh) and wingless (wg) embryos, which indicates that oro functions in determining embryonic segment polarity. Evidence that oro function is involved in Hh signal transduction during embryogenesis is provided by its genetic interactions with the segment polarity genes patched (ptc) and fused (fu). Furthermore, ptc(IN) is a dominant suppressor of the oro embryonic lethal phenotype, suggesting a close and dose-dependent relationship between oro and ptc in Hh signal transduction. oro function is also required in imaginal development. The oro(1) allele significantly reduces decapentaplegic (dpp), but not hh, expression in the eye imaginal disc. Furthermore, oro enhances the fu(1) wing phenotype in a dominant manner. Based upon the interactions of oro with hh, ptc, and fu, we propose that the oro gene plays important roles in Hh signal transduction.

NASA Astrophysics Data System (ADS)

El proposito de esta investigacion, un estudio cualitativo de caso, fue comparar y contrastar el curriculo vigente de la Escuela de Optometria de la UIAPR con las competencias y estandares requeridos por las agencias de acreditacion y de revalida. Con este proposito, decidimos realizar una revision y un analisis de documentos: el prontuario de cada uno de los cursos de los curriculos implantados en el 1993 y en el 2001; las competencias y estandares establecidos por las agencias de revalida y de acreditacion; y las estadisticas en las que se analiza el porcentaje de estudiantes que aprueban cada una de las partes de los examenes de revalida entre el 1998 al 2003. Se realizaron entrevistas dirigidas para dar apoyo y complementar la revision y el analisis de estos documentos. Los participantes de las entrevistas fueron tres estudiantes de la clase de optometria del 2004 (ultima clase del curriculo del 1993); tres estudiantes de la clase de optometria del 2005 (primera clase graduanda del curriculo vigente) y tres profesores y/o directores de los Departamentos de Ciencias Basicas, Ciencias Clinicas y Cuidado al Paciente. Esta investigacion se enmarco en el modelo de evaluacion curricular de discrepancia de Malcolm Provus y en el modelo de desarrollo basado en competencias. Uno de los hallazgos mas importantes del estudio es que los cambios que se implantaron al curriculo del 2001 no han logrado que los estudiantes mejoren su ejecucion en los examenes de revalida. Por otro lado, se encontro que el curriculo vigente atiende completamente los estandares de la practica de Optometria, pero no las competencias. Esta informacion fue validada mediante el uso de una tabla de cotejo para el analisis de los cursos y de la informacion obtenida de las entrevistas. El estudio determina y concluye que existen discrepancias entre los prontuarios de los cursos del curriculo y las competencias requeridas por la agencia de revalida. Segundo, que el Departamento de Ciencias Basicas es el que presenta mas deficiencias en el desarrollo de las competencias. El investigador recomienda disenar e implantar un curriculo basado en competencias y proveer formacion en didactica y procesos de aprendizaje a los profesores.

Synthesis, characterization, and glutathionylation of cobalamin model complexes [Co(N4PyCO2Me)Cl]Cl2 and [Co(Bn-CDPy3)Cl]Cl2.  


Synthetic Co(III) complexes containing N5 donor sets undergo glutathionylation to generate biomimetic species of glutathionylcobalamin (GSCbl), an important form of cobalamin (Cbl) found in nature. For this study, a new Co(III) complex was synthesized derived from the polypyridyl pentadentate N5 ligand N4PyCO(2)Me (1). The compound [Co(N4PyCO(2)Me)Cl]Cl(2) (3) was characterized by X-ray crystallography, UV-vis, IR, (1)H NMR, and (13)C NMR spectroscopies and mass spectrometry (HRMS). Reaction of 3 with glutathione (GSH) in H(2)O generates the biomimetic species [Co(N4PyCO(2)Me)(SG)](2+) (5), which was generated in situ and characterized by UV-vis and (1)H NMR spectroscopies and HRMS. (1)H NMR and UV-vis spectroscopic data are consistent with ligation of the cysteine thiolate of GSH to the Co(III) center of 5, as occurs in GSCbl. Kinetic analysis indicated that the substitution of chloride by GS(-) occurs by a second-order process [k(1) = (10.1 ± 0.7) × 10(-2) M(-1) s(-1)]. The observed equilibrium constant for formation of 5 (K(obs) = 870 ± 50 M(-1)) is about 3 orders of magnitude smaller than for GSCbl. Reaction of the Co(III) complex [Co(Bn-CDPy3)Cl]Cl(2) (4) with GSH generates glutathionylated species [Co(Bn-CDPy3)(GS)](2+) (6), analogous to 5. Glutathionylation of 4 occurs at a similar rate [k(2) = (8.4 ± 0.5) × 10(-2) M(-1) s(-1)], and the observed equilibrium constant (K(obs) = 740 ± 47 M(-1)) is slightly smaller than for 5. Glutathionylation showed a significant pH dependence, where rates increased with pH. Taken together, these results suggest that glutathionylation is a general reaction for Co(III) complexes related to Cbl. PMID:22316335

Has allogeneic stem cell cryopreservation been given the 'cold shoulder'? An analysis of the pros and cons of using frozen versus fresh stem cell products in allogeneic stem cell transplantation.  


Donor stem cells for allogeneic transplant traditionally are collected and transfused 'fresh' into the recipient on the day of transplant; alternatively such cells can be collected in advance and cryopreserved until needed. Most centers favor the former approach based on theoretical concerns that cryopreservation and thawing may worsen clinical outcomes. Limited published data from single institution retrospective studies show no significant impairment of engraftment or reduced day 100 survival for cryopreserved bone marrow recipients. There are no reported outcomes for recipients of cryopreserved peripheral blood allografts. Use of cryopreserved stem cells is associated with a higher incidence of adverse events (transfusion reactions, bacterial graft contamination and collection of grafts which are not utilized). Conversely, use of cryopreserved grafts introduces a greater flexibility into a stressed healthcare system and results in a more streamlined experience for the donor. Some data suggest that transplantation with a cryopreserved product may lower the incidence of acute graft-versus-host disease. We compare the pros and cons of using 'fresh' versus cryopreserved stem cell products for allogeneic transplantation and suggest that the current standard of using 'fresh' products may not be warranted. We also suggest future areas of exploration to better elucidate this issue. PMID:16892075

Brewers' spent grain (BSG) protein hydrolysates decrease hydrogen peroxide (H2O2)-induced oxidative stress and concanavalin-A (con-A) stimulated IFN-? production in cell culture.  


The present study investigated the bioactivity of protein hydrolysates and fractionated hydrolysates prepared from brewers' spent grain (BSG) using proteases, including Alcalase 2.4L, Flavourzyme and Corolase PP. Hydrolysates were designated K-Y, including fractionated hydrolysates with molecular weight (m.w.) < 3, <5 and >5 kDa. Where computable, IC50 values were lower in U937 (1.38-9.78%) than Jurkat T cells (1.15-13.82%). Hydrolysates L, Q and R and fractionated hydrolysates of U and W (<3, <5, >5 kDa) significantly (P < 0.01) protected against hydrogen peroxide (H2O2)-induced reduction of superoxide dismutase (SOD) activity. A fractionated hydrolysate of W (<5 kDa) protected against H2O2-induced DNA damage, P < 0.01. Hydrolysates K, N, P, U, U > 5 kDa, V, V > 5 kDa, W, W > 5 kDa significantly (P < 0.05) reduced a concanavlin-A (con-A) stimulated production of interferon-? (IFN-?). In conclusion, BSG protein hydrolysates demonstrate bioactivity in vitro; lower m.w. hydrolysates (<3, <5 kDa) show greatest antioxidant activity and unfractionated or higher m.w. hydrolysates (>5 kDa) possess anti-inflammatory effects.

Pros and cons of subpectoral implantation.  


At the present time, there is no universally accepted surgical technique or prosthesis for augmenting breast volume. Each surgeon has to choose with regard to shape, consistency, and volume, according to his own conviction and respecting his patient's priorities. These priorities will vary with age, profession, sexual habits, and marital and social status. In order to get the best possible results, the plastic surgeon should be adept at alternative methods and should not be restricted to one technique or one prosthesis. Patients vary considerably so our methods should be diversified. Our subpectoral implantations have given us better results than our retroglandular ones, which have been performed during the same period of time and with the same prosthesis. Consequently, retropectoral implantation is still our preferred procedure. We think that this technique, with its proper indications, deserves wider application. PMID:1261186

Nanoparticles: Health Effects--Pros and Cons  

PubMed Central

With the advent of nanotechnology, the prospects for using engineered nanomaterials with diameters of < 100 nm in industrial applications, medical imaging, disease diagnoses, drug delivery, cancer treatment, gene therapy, and other areas have progressed rapidly. The potential for nanoparticles (NPs) in these areas is infinite, with novel new applications constantly being explored. The possible toxic health effects of these NPs associated with human exposure are unknown. Many fine particles generally considered “nuisance dusts” are likely to acquire unique surface properties when engineered to nanosize and may exhibit toxic biological effects. Consequently, the nuisance dust may be transported to distant sites and could induce adverse health effects. In addition the beneficial uses of NPs in drug delivery, cancer treatment, and gene therapy may cause unintentional human exposure. Because of our lack of knowledge about the health effects associated with NP exposure, we have an ethical duty to take precautionary measures regarding their use. In this review we highlight the possible toxic human health effects that can result from exposure to ultrafine particles (UFPs) generated by anthropogenic activities and their cardiopulmonary outcomes. The comparability of engineered NPs to UFPs suggests that the human health effects are likely to be similar. Therefore, it is prudent to elucidate their toxicologic effect to minimize occupational and environmental exposure. Highlighting the human health outcomes caused by UFPs is not intended to give a lesser importance to either the unprecedented technologic and industrial rewards of the nanotechnology or their beneficial human uses.

Planetas extrasolares con pequeño semieje orbital  

NASA Astrophysics Data System (ADS)

The discovery of extra-solar planets, first surrounding a pulsar (PSR1257+12, Malhotra et al 1992) and then main-sequence stars similar to our sun, ( has opened a new field of study inside the dynamic of planetary systems. Although the information we have of these objects is determined by the own limitations of the detection methods that are used, important differences between these systems and the Solar System were observed. The mass of these planets are, in general, bigger than Jupiter, the measured semimayor axes have a low limit of 0.04 AU, the ten part of Mercury semimayor axe. Further, the excentricities take different values from almost 0 to 0.93, in contrast to our system where the planetary orbits are approximately circular. Among the extra solar planets detected until August 2002, it is possible to observe a deficiency of massive planets (Mp sin I < 3.5 Mj) near the primary star, i.e. semimayor axe below 0.1 AU, with excentricity below 0.2. The goal of this work is to attempt an explanation of these cases by an eliptic planar model in which two point planets interac gravitationaly. The motion equations are analized for different initial conditions by using numerical methods. The motion equations were stated and several pairs of particles were generated by varying the relative masses and the orbital elements. To integrate the equations the Bulirsh - Stoer code was used, with a 10-12 accuracy. As a control variable of the results the calculus of energy was used. The total span of integrations was 106 years. The outputs of the numerical simulations show several dynamic behaviors for the particles: - Lower mass escapes to the outside of the system - Stability in both bodies - Less massive planet fall to the primary star Moreover, by comparing the results obtained for objets with identical initial conditions in their orbital parameters, but with different relations of mass, it is possible to distinguish two types of behaviours: - during the integration time there is dynamical estability if both masses are below 3.5Mj. - the less massive planet fall to the star if the other mass is about 10Mj. in this case the major body increase his semimajor axe in order to preserve the constancy of the angular moment of the total system. The simulations performed have shown results with a high dependence of the values of the initial conditions and the masses of the planets considered.

The pros and cons of phytoestrogens  

PubMed Central

Phytoestrogens are plant derived compounds found in a wide variety of foods, most notably soy. A litany of health benefits including a lowered risk of osteoporosis, heart disease, breast cancer, and menopausal symptoms, are frequently attributed to phytoestrogens but many are also considered endocrine disruptors, indicating that they have the potential to cause adverse health effects as well. Consequently, the question of whether or not phytoestrogens are beneficial or harmful to human health remains unresolved. The answer is likely complex and may depend on age, health status, and even the presence or absence of specific gut microflora. Clarity on this issue is needed because global consumption is rapidly increasing. Phytoestrogens are present in numerous dietary supplements and widely marketed as a natural alternative to estrogen replacement therapy. Soy infant formula now constitutes up to a third of the US market, and soy protein is now added to many processed foods. As weak estrogen agonists/antagonists with molecular and cellular properties similar to synthetic endocrine disruptors such as Bisphenol A (BPA), the phytoestrogens provide a useful model to comprehensively investigate the biological impact of endocrine disruptors in general. This review weighs the evidence for and against the purported health benefits and adverse effects of phytoestrogens.

Omega-3 in antiarrhythmic therapy : cons position.  


The association between omega-3 (n-3 polyunsaturated fatty acids) and the clinical outcome of patients with cardiovascular diseases such as coronary heart disease is currently unclear, especially regarding its possible antiarrhythmic effects and the not quite understood mechanisms of action. In the last 15 years, several epidemiological studies have shown a lower incidence of sudden cardiac death with a diet rich in omega-3 or fish consumption. The antiarrhythmic properties related to omega-3 have been related to modulation of sodium-dependent ion channels or sodium-calcium exchangers of myocytes through a reduction of their excitability especially in ischaemic or damaged myocardial tissue. However, the results of experimental studies have not always been consistent. Although the role of omega-3 in preventing sudden cardiac death has been evaluated in several clinical trials that included patients with coronary artery disease (particularly in patients with post-myocardial infarction), the interpretation of such data must be treated with extreme caution. In particular, while a reduction in cardiac death was demonstrated by a meta-analysis of several randomized clinical trials, a reduced risk of sudden cardiac death has been described only in the GISSI-Prevenzione study, while in other studies the evidence that emerged is more controversial, with wide confidence intervals that support the possibility of heterogeneity in the distribution of the factors involved in the efficacy of treatment. Omega-3 is probably involved in the prevention of cardiovascular mortality through different mechanisms, and it is crucial to study its association with other drugs such as ACE inhibitors or calcium channel blockers. The study of antiarrhythmic drugs has been divided into prevention of supraventricular and ventricular arrhythmias. In these conditions, the role of omega-3 seems to be more pronounced in atrial tachyarrhythmias such as atrial fibrillation, but does not have a role in ventricular arrhythmias. In summary, the antiarrhythmic effect of omega-3 is not clearly evident and further studies are needed to investigate its beneficial effect in cardiac mortality compared with arrhythmic death.

Payment for donor kidneys: pros and cons.  


Continuous growth of the end stage renal disease population treated by dialysis, outpaces deceased donor kidneys available, lengthens the waiting time for a deceased donor transplant. As estimated by the United States Department of Health & Human Services: '17 people die each day waiting for transplants that can't take place because of the shortage of donated organs.' Strategies to expand the donor pool--public relations campaigns and Drivers' license designation--have been mainly unsuccessful. Although illegal in most nations, and viewed as unethical by professional medical organizations, the voluntary sale of purchased donor kidneys now accounts for thousands of black market transplants. The case for legalizing kidney purchase hinges on the key premise that individuals are entitled to control of their body parts even to the point of inducing risk of life. One approach to expanding the pool of kidney donors is to legalize payment of a fair market price of about 40,000 dollars to donors. Establishing a federal agency to manage marketing and purchase of donor kidneys in collaboration with the United Network for Organ Sharing might be financially self-sustaining as reduction in costs of dialysis balances the expense of payment to donors.

Natural-born con artists and counterfeiters  

PubMed Central

Deception is ubiquitous in plant and animal kingdoms and is widely thought to provide selective advantages to the individual and evolutionary success to the species. Mimicry, a form of deception whereby an individual imitates their model to advantage by closely resembling their behavior or appearance, is particularly well documented and represented by the peripheral eyespots seen on the wings of many butterfly species. The significance of butterfly eyespots has been convincingly demonstrated to serve as an anti-predatory function either by imitation of a predator’s own dangerous enemies (intimidation hypothesis) or by deflecting predator strikes toward less-vital parts of the body (deflection hypothesis). A convincing and compelling explanation in butterflies, the functional role of eyespots as anti-predatory devices has become a widely held and firmly entrenched belief that has been freely adopted into other systems. Here we comment on a recent paper that demonstrates a vastly different role for eyespots, that of intra-specific male-male competition, and make the point that even long-held beliefs need to be tested and challenged under different contexts if we are not to be deceived ourselves.

WGS Catalysis and In Situ Studies of CoO1-x, PtCon/Co3O4, and PtmCom'/CoO1-x Nanorod Catalysts.  


Water-gas shift (WGS) reactions on Co3O4 nanorods and Co3O4 nanorods anchoring singly dispersed Pt atoms were explored through building correlation of catalytic performance to surface chemistry of catalysts during catalysis using X-ray absorption spectroscopy, ambient pressure X-ray photoelectron spectroscopy (AP-XPS), and environmental TEM. The active phase of pure Co3O4 during WGS is nonstoichiometric cobalt monoxide with about 20% oxygen vacancies, CoO0.80. The apparent activation energy (Ea) in the temperature range of 180-240 °C is 91.0 ± 10.5 kJ mol(-1). Co3O4 nanorods anchoring Pt atoms (Pt/Co3O4) are active for WGS with a low Ea of 50.1 ± 5.0 kJ mol(-1) in the temperature range of 150-200 °C. The active surface of this catalyst is singly dispersed Pt1Con nanoclusters anchored on Co3O4 (Pt1/Co3O4), evidenced by in situ studies of extended X-ray absorption fine structure spectroscopy. In the temperature range of 200-300 °C, catalytic in situ studies suggested the formation of PtmCom' nanoclusters along with the reduction of Co3O4 substrate to CoO1-x. The new catalyst, PtmCom'/CoO1-x is active for WGS with a very low Ea of 24.8 ± 3.1 kJ mol(-1) in the temperature range of 300-350 °C. The high activity could result from a synergy of PtmCom' nanoclusters and surface oxygen vacancies of CoO1-x. PMID:23611190

The selected coordination chemistry of L1, L3, and L5with [UO(2)(NO(3))(2)] and [Ce(NO(3))(3)] has been evaluated. The structures of the compounds [UO(2)(NO(3))(2)(PhSOCH(2)CON(i)Bu(2))](10) and [Ce(NO(3))(3)(PhSOCH(2)CONBu(2))(2)](12) have been determined by single crystal X-ray diffraction methods. Preliminary extraction studies of ligand L6 with U(VI), Pu(IV) and Am(III) in tracer level showed an appreciable extraction for U(VI) and Pu(IV) in up to 10 M HNO(3) but not for Am(III). Thermal studies on compounds 8 and 10 in air revealed that the ligands can be destroyed completely on incineration. The electron spray mass spectra of compounds 8 and 10 in acetone show that extensive ligand distribution reactions occur in solution to give a mixture of products with ligand to metal ratios of 1: 1 and 2 :1. However, 10 retains its solid state structure in CH(2)Cl(2). PMID:15510283

Histochemical and immunohistochemical characterization of exocrine cells in the foregut of the red-eared slider turtle, Trachemys scripta (Emydidae).  


The morphofunctional organization of the exocrine cells in the foregut of the red-eared slider turtle, Trachemys scripta, was investigated by histochemistry (PAS, AB pH1.0 and pH 2.5, HID-AB, Bowie), lectin-histochemistry (WGA, SBA, UEA, ConA, PNA, DBA, sialidase-SBA, sialidase-PNA, Paradoxical ConA), and immunohistochemistry (antipepsin, anti-alpha-H+,K+ ATPase) to detect regional differences and verify the existence of an oro-aboral gradient in gastric juice secretion. Observations showed that pharyngeal goblet cells have mucins with terminal residuals of GalNAc and sialic acid. In the oesophagus, sulphomucins in the goblet cells are progressively substituted by sialomucins and no glands are found. Gastric surface cells secrete mostly sialomucins with residuals of GlcNAc and GalNAc. The cardias presents glands with cells secreting mostly sialomucins, differing from the surface ones in having GalNAcalpha1,3GalNAc sequences. The fundus presents complex glands with main and lesser tubules. Cells in the main tubules secrete stable, class-III mucins with sialylated residuals of glucose and/or mannose, GalNAcalpha1, 3GalNAc, and Galbeta1,3GalNAc sequences. In the lesser tubules, the oxynticopeptic cells are found, presenting pepsinogen granules and an affinity to the anti-alpha-H+,K+ ATPase, without any oro-aboral variation. The pyloric glands have a secretion similar to that of the neck cells of the fundic glands, consisting of stable, class-III mucins mostly sialylated with a high heterogeneity of residuals such as glucose and/or mannose, fucose, GlcNAc, and GalNAc. Mucins in the foregut are probably involved in several functions such as lubrication, protection against gastric juice, osmotic regulation to increase intestinal absorption, and protection against microbial injuries.

Debate: Does genetic information in humans help us treat patients? PRO--genetic information in humans helps us treat patients. CON--genetic information does not help at all.  


PRO: In the past decade, genotyping has started to help the neurologic practitioner treat patients with three types of epilepsy causing mutations, namely (1) SCN1A, a sodium channel gene mutated in Dravet's sporadic severe myoclonic epilepsy of infancy (SMEI and SMEB); (2) laforin (dual specificity protein phosphatase) and malin (ubiquitin E3 ligase) in Lafora progressive myoclonic epilepsy (PME); and (3) cystatin B in Unverricht-Lundborg type of PME. Laforin, malin, and cystatin B are non-ion channel gene mutations that cause PME. Genotyping ensures accurate diagnosis, helps treatment and genetic counseling, psychological and social help for patients and families, and directs families to organizations devoted to finding cures for specific epilepsy diseases. In SCN1A and cystatin B mutations, treatment with sodium channel blockers (phenytoin, carbamazepine, oxcarbazepine, lamotrigine) should be avoided. Because of early and correct diagnosis by genotyping of SCN1A mutations, the avoidance of sodium channel blockers, and aggressive treatment of prolonged convulsive status, there is hope that Dravet's syndrome may not be as severe as observed in all past reports. Genotyping also identifies nonsense mutations in Lafora PME. Nonsense mutations can be corrected by premature stop codon readthrough drugs such as gentamicin. The community practitioner together with epilepsy specialists in PME can work together and acquire gentamicin (Barton-Davis et al., 1999) for "compassionate use" in Lafora PME, a generalized lysosome multiorgan storage disorder that is invariably fatal. In Unverricht-Lundborg PME, new cohorts with genotyped cystatin B mutations have led to the chronic use of antioxidant N-acetylcysteine and combination valproate clobazam or clonazepam plus antimyoclonic drugs topiramate, zonisamide, piracetam, levetiracetam, or brivaracetam. These cohorts have minimal ataxia and no dementia, questioning whether the syndrome is truly progressive. In conclusion, not only is genotyping a prerequisite in the diagnosis of Dravet's syndrome and the progressive myoclonus epilepsies, but it also helps us choose the correct antiepileptic drugs to treat seizures in Dravet's syndrome and Unverricht-Lundborg PME. Genotyping also portends a brighter future, helping us to reassess the true course, severity, and progressive nature of Dravet's syndrome and Unverricht-Lundborg PME and helping us craft a future curative treatment for Dravet's syndrome and Lafora disease. Without the genotyping diagnosis of epilepsy causing mutations we are stuck with imprecise diagnosis and symptomatic treatment of seizures. CON: Genotyping of epilepsy may help to better understand the genetics of epilepsy, to establish an etiology in a patient with epilepsy, to provide genetic counseling, and to confirm a clinical diagnosis. However, critical analysis reveals that genotyping does not contribute to an improved treatment for the patients. In order to improve treatment, genotyping would have to (1) improve our ability to select the drug of choice for a given epilepsy or epileptic syndrome; (2) improve our ability to predict the individual risk of adverse reactions to certain drugs; (3) improve our ability to avoid unnecessary treatments or treatments that could aggravate seizures. Many example illustrate the lack of impact of genetic information on the treatment outcome: we do not treat Dravet syndrome more successfully since SCN1A testing became available; we do not treat Lafora disease more successfully since testing for laforin and malin became available; we do not need to know the genetic nature of Unverricht-Lundborg disease or test for the cystatin B mutation in order to select or avoid certain drugs; we do not treat Rett syndrome more successfully since MECP2 testing became available; we do not treat JME more successfully since we know its genetic origin; we do not treat autosomal dominant nocturnal frontal lobe epilepsy more successfully since we know its genetic origin and can test for its mutation. The clinical characteristics as well as the

The nature of the Ailao Shan-Red River (ASRR) shear zone: Constraints from structural, microstructural and fabric analyses of metamorphic rocks from the Diancang Shan, Ailao Shan and Day Nui Con Voi massifs  

NASA Astrophysics Data System (ADS)

The structural geology, timing of shearing, and tectonic implications of the ASRR shear zone, one of the most striking lineaments in Southeast Asia, have been the topics of extensive studies over the past few decades. The Xuelong Shan (XLS), Diancang Shan (DCS), Ailao Shan (ALS) and Day Nui Con Voi (DNCV) metamorphic massifs along the shear zone have preserved important information on its structural and tectonic evolution. Our field structural analysis, detailed microstructural and fabric analysis, as well as the quartz, sillimanite and garnet fabric studies of the sheared rocks from the massifs demonstrate the dominant roles of three deformation episodes during Cenozoic tectonic evolution in the shear zone. Among the contrasting structural and microstructural associations in the shear zone, D2 structures, which were formed at the brittle to ductile transition during large-scale left-lateral shearing in the second deformation episode, predominate over the structural styles of the other two deformation episodes. Discrete micro-shear zones with intensive grain size reduction compose the characteristic structural style of D2 deformation. In addition, several types of folds (early shearing folds, F21, and late-shearing folds, F22) were formed in the sheared rocks, including discrete to distributed mylonitic foliation, stretching lineation and shear fabrics (e.g., mica fish, domino structures, as well as sigma and delta fabrics). A sequence of microstructures from syn-kinematic magmatic flow, high-temperature solid-state deformation, to brittle-ductile shearing is well-preserved in the syn-kinematic leucocratic intrusions. Deformation structures from the first episode (D1) are characterized by F1 folds and distributed foliations (S1) in rocks due to pure shearing at high temperatures. They are preserved in weakly sheared (D2) rocks along the eastern margin of the ALS belt or in certain low-strain tectonic enclaves within the shear zone. Furthermore, semi-brittle deformation structures, such as hot striae and discrete retrogression zones, are attributed to normal-slip shearing in the third deformation episode (D3), which was probably locally active, along the eastern flank of the DCS range, for example.There are four quartz c-axis fabric patterns in the mylonitic rocks, including type A point maxima, type B Y point maxima with crossed girdles superimposition, type C quadrant maxima, as well as type D point and quadrant maxima combination. They are consistent with microscopic observations of microstructures of high-temperature pure shearing, low-temperature simple shearing and their superimposition. Integrated microstructural analysis and fabric thermometer studies provide information on both high temperature (up to 750 °C) and dominant low-temperature (300-600 °C) deformations of quartz grains in different rock types. Sillimanite and garnet fabrics, especially the latter, were primarily formed at the peak metamorphism during high-temperature pure shearing.The above structural, microstructural and fabric associations were generated in the tectonic framework of the Indian-Eurasian collision. The low-temperature microstructures and fabrics are attributed to left-lateral shearing along the ASRR shear zone from 27 to 21 Ma during the southeastward extrusion of the Indochina block, which postdated high-temperature deformation at the peak metamorphism during the collision.

Proteins that fuse and fragment mitochondria in apoptosis: con-fissing a deadly con-fusion?  


During apoptosis, mitochondria undergo multiple changes that culminate in the release of cytochrome c and other proapoptotic cofactors. Recently, a role for previously overlooked morphological changes, fission of the mitochondrial reticulum and remodeling of mitochondrial cristae, has been suggested in mammalian cells and in developmental apoptosis of C. elegans. Mitochondrial morphology is determined by fusion and fission processes, controlled by a growing set of "mitochondria-shaping" proteins, whose levels and function appear to regulate the mitochondrial pathways of cell death. Expression of pro-fusion proteins, as well as of inhibition of pro-fission molecules reduces apoptosis, suggesting a linear relationship between fragmentation and death. Mechanisms by which mitochondrial fragmentation promotes apoptosis and interactions between fragmentation and remodeling of the inner membrane are largely unclear. A tempting, unifying hypothesis suggests that fission is coupled to cristae remodeling to maximize cytochrome c release. PMID:16167173

Biochemical characterization of the eelgrass Zostera marina at its southern distribution limit in the North Pacific [Caracterizacio??n bioqui??mica del pasto marino Zostera marina en el li??mite sur de su distribucio??n en el Paci??fico Norte  

USGS Publications Warehouse

The eelgrass Zostera marina L. is distributed along the Baja California Peninsula (Mexico) where it is exposed to a wide range of irradiances and temperatures that could promote changes in its biochemical composition. Consequently, the objective of this study was to characterize the variations in the levels of chlorophyll, carbohydrates, proteins, fiber, ash and calories in the shoots of Z. marina from the north (San Quintin) and south (Ojo de Liebre and San Ignacio lagoons) of the peninsula. Temperature in the southern lagoons was 5-6??C higher than in the northern lagoon; likewise, in situ irradiance was two-fold greater in the south than in the north. As a result of the lower irradiance levels, the concentration of chlorophyll in the shoots of Z. marina was twice as high (1.7 mg gWW-1) in the northern lagoon than in the southern ones (0.8 mg gWW-1). Similar to chlorophyll levels, the concentration of soluble carbohydrates in the shoots was greater in the northern lagoon than in the southern ones, suggesting that the high levels of chlorophyll are enough to compensate for the low irradiance levels and to maintain a positive carbon balance at San Quintin. On the other hand, the levels of proteins in the shoots from the north of the peninsula were slightly lower than those from the southern populations. In general, these results suggest that the different environmental conditions to which Z. marina is exposed along the peninsula impact its biochemical composition.

USGS Publications Warehouse

Apparent threats to the spatial distribution of seagrass in San Quinti??n Bay prompted us to make a detailed assessment of habitats in the bay. Six coastal habitats and three seagrass subclasses were delineated using airborne digital multispectral videography (DMSV), Eelgrass, Zostera marina, was the predominant seagrass and covered 40% (1949 ha) of the areal extent of the bay in 1999. Eelgrass grew over a wide range of tidal depths from about -3.0 in mean lower low water (MLLW) to about 1.0 m MLLW, but greatest spatial extent occurred in intertidal areas -0.6 m to 1.0 m MLLW. Exposed-continuous (i.e., high density) eelgrass was the most abundant habitat in the bay. Widgeongrass, Ruppia maritima, was the only other seagrass present and covered 3% (136 ha) of the areal extent of the entire bay. Widgeongrass grew in single species stands in the upper intertidal (??? 0.4 MLLW) and intermixed with eelgrass at lower tidal depths. Overall accuracy of the six habitat classes and three subclasses in the DMSV map was relatively high at 84%. Our detailed map of San Quintin Bay can be used in future change detection analyses to monitor the health of seagrasses in the bay.

The pros and cons of polyethylene sterilization with gamma irradiation.  


This retrospective study evaluated the implant, patient and surgical factors associated with polyethylene wear for one type of porous-coated hemispheric total hip arthroplasty cup. Radiographic wear measurements among 567 Duraloc cups (512 patients) revealed that liners sterilized by gamma-irradiation wore 0.085 mm/year less than those that were sterilized by gas-plasma, a noncross-linking chemical surface treatment. The substantially decreased wear rate associated with gamma-irradiation was attributed to sterilization-induced polyethylene cross-linking. Shelf-aging adversely affected liners that were gamma irradiated in air. On average, highly crystalline Hylamer liners showed a 0.064 mm/year increase in wear rates for each year of shelf storage after terminal sterilization with gamma-irradiation in air. Among conventional Enduron liners, the effect of shelf aging after gamma-irradiation in air was more modest, increasing wear rates by 0.014 mm/year for each year of shelf storage. Because Hylamer's wear performance degraded at about five times the rate of Enduron's, the improved wear resistance associated with gamma-irradiation in air would be lost after 1.3 years of shelf aging for Hylamer compared with 6.1 years for Enduron. For every additional year of age at the time of surgery, the wear rate decreased by 0.003 mm/year. Increased body mass index, a preoperative diagnosis of inflammatory arthritis, and a ceramic femoral head also were associated with decreased wear rates. PMID:15577466

Pros and cons of stem cell transplantation for autoimmune disease.  


The data and discussion at this symposium have provided a most useful analysis of the autoimmune diseases and their potential for therapy by stem cell transplantation. These diseases are characterized by threat to life and particularly by chronic, painful and debilitating courses that warrant aggressive therapy. Selection of patients will be difficult because of the variable disease course and the necessity to choose patients who still have reversible disease. The safety of both autologous and allogeneic stem cell grafting has progressed to the point where, in many cases, the risks of the disease far outweigh those of transplantation. In my opinion the data presented at this symposium show that we should proceed cautiously with both autologous and allogeneic stem cell grafts. Purified stem cells, which have the advantage of being free of lymphocytes, should be used for the first series of autologous studies. These studies are attractive because of the low risk of transplant related complications but are less likely to be curative. Allogeneic grafts from perfectly matched donors have the advantage of providing a completely new immunological environment. For this reason, I believe that curative results are most probable after allogeneic stem cell engraftment. Emphasis should be on the identification of patients with HLA matched siblings. Initially, these studies will be carried out in patients with advanced disease, as was the case in the early days of transplantation for leukemia. In considering more aggressive treatment for autoimmune diseases it appears there are 3 possible approaches. First, and most conservative, is to store peripheral blood stem cells for possible future marrow rescue and then to give higher doses of immunosuppressive agents, especially in combination, to see whether there is an improvement over conventional doses. Second, for those who prefer a conservative approach to stem cell transplantation, is to give myeloablative and lymphoablative chemotherapy followed by purified (lymphocyte-free) hematopoietic stem cells. Third, and most likely to be curative, is myeloablative and lymphoablative therapy followed by stem cells from an HLA matched family member with subsequent short methotrexate and cyclosporine treatment to control GVHD. As we have heard, there are differences of opinion about whether the preparative regimen should include irradiation. It should be pointed out that total body irradiation is the most effective way to destroy lymphoid cells throughout the body. Careful monitoring of accumulating clinical results will pilot future investigation. PMID:9150129

[Hematopoietic stem cell transplantation in autoimmune diseases. Pros and cons  


New therapeutics have clearly advanced our chances of inducing remission in several aggressive autoimmune diseases like rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE). Despite this, subgroups of patients with RA or SLE or of other diseases like systemic sclerosis (SSc) or multiple sclerosis (MS) still present a poor response to conventional drugs. In this kind of patients, haematopoietic stem cell transplantation (HSCT) provided important clinical benefits in several studies. This might depend upon several possible mechanisms such as purging of autoreactive T cells during conditioning or changes of the TH1/TH2 biological milieu. An overview of the results obtained so far, the drawbacks and the perspectives in this field are presented. PMID:12461572

Umbilical cord blood transplantation: pros, cons and beyond.  


Large body of clinical and scientific data has been generated since the first cord blood transplantation (CBT) was performed in 1989. Superior immune plasticity of CB grafts, that allows for less stringent HLA matching, is especially valuable in the face of a persistently growing need for unrelated donor (UD) transplants. Limited cell dose remains the main setback of CBT, particularly in adult population. New strategies, such as transplantation with two cord blood units or using non-myeloablative conditioning, have remarkably expanded the availability of CB transplants in adults with hematological malignancies. Clinical trials with in vitro expanded CB-derived stem cells are under way. Currently cord blood is considered a second best choice after matched bone marrow. However, results of recent international studies indicate that in particular clinical settings, such as in children with leukemia, CB may become a frontline hematopoietic stem cell (HSC) source for transplantation. Recent advances in understanding the unique biology of cord blood will further expand indications for its use in different settings, including those beyond hematopoietic stem cells transplantation (HSCT).

Screening MR imaging versus screening ultrasound: pros and cons.  


Data support greater sensitivity of MR imaging compared with mammography and ultrasound in high-risk populations, in particular BRCA 1 and BRCA 2 carriers. Screening ultrasound improves cancer yield versus mammography alone in high-risk patients and in patients with dense breasts and is less expensive. Drawbacks include low positive predictive value, operator dependence, and significant physician time expenditure. Advances, such as refinement of automated whole-breast ultrasound, new outcomes data from ultrasound-detected masses in BI-RADS 3 and 4a categories, and development of new MR imaging sequences that allow rapid screening, potentially without use of contrast, will likely reveal the most appropriate tool over time.

Cervicogenic headache: the neck is a generator: con.  


Cervicogenic headache (CeH) is a well-recognized headache syndrome, distinguishable from other primary and secondary headaches. Although in some cases a cervical lesion may be detected in connection with the headache, many CeH patients have no demonstrable lesion. Besides, most of the frequent cervical diseases, such as spondylosis and disc herniations, do not present with headache of the cervicogenic type. This suggests that the neck is not an independent headache generator. CeH may depend in addition on a central predisposition counterpart, leading to the activation of the trigeminovascular system and pain generation. PMID:20456157

Pros and cons of the nonsurgical treatments for gallbladder stones.  


Dissolution of gallbladder stones is usually possible if the cholesterol content of the stones is high. Oral treatment with chenodiol or ursodiol is least invasive, but also least effective and slow. methyl tert-butyl ether requires delivery by percutaneous transhepatic catheter, but is rapidly effective. Extracorporeal shock wave lithotripsy enhances dissolution by oral bile acids, but is highly effective only for solitary stones less than or equal to 20 mm in diameter. Percutaneous cholecystostomy is most invasive, but effective regardless of stone composition. Stones will probably recur in 50 percent of patients with a patent cystic duct and intact gallbladder.

A prototype for ovulation detection: pros and cons.  


A noninstrumented enzyme immunoassay for urinary estrone conjugates was adapted from an instrumented microtiter plate enzyme immunoassay assay. The end point of the assay was a color change from green to clear, which was visible to the unaided eye. The visible color change was adjusted to allow 80 ng/ml estrone conjugates (on the basis of a sample size of 6.5 microliters urine) to be distinguished from an infinite dilution without instrumentation. The evaluation of human urine collected from ovulatory ovarian cycles demonstrated that early follicular phase concentrations (35.9 +/- 6.8 to 79.4 +/- 14.7 ng/ml, n = 10) produced a dark-green color, whereas late follicular phase concentrations (162.9 +/- 20.1 ng/ml, n = 10) produced no color. Daily urine samples throughout 10 ovulatory ovarian cycles produced parallel profiles when compared to measurements of estradiol in paired blood samples. Complete analysis of the data indicated that ovarian follicular dynamics can be accurately monitored through the noninstrumented analysis of daily estrone conjugates in urine samples. PMID:1755459

Fixed-dose combination therapy in hypertension: cons.  


The goal of antihypertensive therapy is to reduce the risk associated with blood pressure elevation. Although the choice of first-line drug therapy may exert some effects on different long-term cardiovascular endpoints, randomized clinical trials and meta-analyses demonstrated that blood pressure reduction per se is the primary determinant in primary and secondary prevention. Numerous analyses carried out over the last years have repeatedly shown that many patients require the combination of two or more drugs to reach the recommended level of blood pressure control. Within this context, combination therapy with separate agents or fixed-dose combination pills offers an attractive ability to lower blood pressure more quickly, decrease adverse effects and reach blood pressure target. It is not clear whether fixed combinations of antihypertensive agents in a single tablet provide a greater benefit than the corresponding components given separately. In other words, it is not clear if the use of fixed combinations translates into a clearly improved blood pressure control and cardiovascular prevention in clinical practice. Fixed-dose combinations may simplify the treatment regimen by reducing the number of pills and may be attractive for many hypertensive patients. However, single-pill (fixed) drug combinations have some disadvantages: (i) branded fixed combinations may be more expensive than equivalent free combinations; (ii) the duration of action of individual components may not be equivalent, and this may not justify a single daily dosing of the combination; and (iii) the use of fixed combinations implies less flexibility in modifying the doses of individual components and the exposure of patients to unnecessary therapy. Moreover, should a patient develop side effects to one component, the entire combination should be discontinued and replaced by free drugs. The following three types of fixed-dose tablets have been recently proposed to give additional flexibility: (i) tablet manufactured so that each of the two drugs is placed at opposite ends of the tablet with a drug-free (inactive) layer placed in between; (ii) tablet with the combination of drugs at each end with the inactive zone in between; and (iii) tablet divided into discrete, separate segments (the two drugs are combined uniformly), which provides benefits for initial close titration and dosage adjustments. Currently, none of the fixed-dose tablets available on the market have these characteristics and, consequently, are unable to be broken to allow sufficient flexibility. PMID:22867089

Interracial prison contact: the pros for (socially dominant) cons.  


Individuals high in social dominance orientation (SDO; Sidanius & Pratto, 1999) endorse group hierarchies and social inequality. Surprisingly little research has addressed contextual factors associated with reduced intergroup biases among such individuals. The present investigation considers a Person x Situation approach to this question in two British prisons, exploring the contextual factors outlined in the Contact Hypothesis (Allport, 1954). White inmates scoring higher in SDO exhibited significantly less in-group bias when reporting increased contact with Black inmates (Studies 1 & 2), when perceiving that favourable contact conditions are institutionally supported (Study 1), or when experiencing more pleasant personal interactions with Black inmates (Study 2). These SDO x Contact Condition moderation effects were mediated in Study 2: among high-SDO individuals, increased empathy towards Black inmates mediated the relation between contact variables and lower in-group bias. Implications for considering individual differences and empathy in contact settings are considered. PMID:17697448

Con: Can biomarkers be gold standards in Alzheimer's disease?  


As Alzheimer's disease remains a clinical diagnosis, and as clinical diagnosis can be difficult, it makes sense to look for so-called biomarkers. A biomarker predicts who is likely to have the illness and who is not. Some biomarkers might even correlate with a clinically meaningful response to treatment. Developing biomarkers is often characterized as searching for a diagnostic gold standard that can seem appealing in its promise of certainty. Even so, considering both the economic history of the gold standard and the results of neuropathological studies, framing the search for measurable, biological correlates of dementia syndromes in this way is likely to be self-defeating. Instead of considering biomarkers as providing certainty through referent criterion validation, currently it makes more sense to test their construct validity and their predictive ability. This means that while biomarkers should inform, they will not dictate clinical meaningfulness. For the foreseeable future, even were they to inform diagnosis, biomarkers cannot substitute for understanding whether patients and caregivers find a given dementia treatment effective. Instead, clinicians should recognize their own determining role, both in dementia diagnosis and in the evaluation of treatment. These roles will best be executed by hearing what patients and caregivers tell us about dementia, and its response to treatment. PMID:20587007

?`Caos en la Resonancia 2:3 con Urano?  

NASA Astrophysics Data System (ADS)

The 2:3 resonace with Uranus and 3:2 with Neptune define limits in the semi -major axis interval, where some objects like 7066 Nessus (semi-major axis 24.456 au) has been observed. In this contribution, we describe the dynamics of a mass-less test particle near the critical value of the semi-major axis for each resonance. We analize the structure of the phase space in each case, using the restricted three-body planar approach, for different values of the Jacobi constant. Although this aproximation does not reflect the whole complexity of this region, it constitutes a good first solution, since there are not first or second order orbital resonances with the major planets. For the 2:3 resonance with Uranus, we find a smooth curve of quasi-periodical orbits surrounding the periodic orbit corresponding to the critical value of the semi-major axis. This region is also surrounded by chaotic orbits, probably due to the presence of other conmensurabilities of first or second order with Uranus. At the internal resonance 3:2 with Neptune, the structure of the section surfaces varies with the value of the C constant. In general, periodic orbits are found for the critical semi-major axis, but for other values of the Jacobi constant, which are obtained modifying the eccentricity of the particle orbit, the region is not closed anymore, so the test particle crosses the Neptune orbit, and escapes from this region.

Early testing for Huntington disease in children: pros and cons.  


We report 2 young children who are examples of the consequences of premature testing for Huntington disease. Premature testing of a child or fetus carries complex medical and psychological issues to both the child and the family that need to be considered and explored more than in an adult with Huntington disease. We suggest that a child at risk for juvenile Huntington disease not be tested until symptoms are progressive and consistent with the disease and all other mimickers are excluded. When testing is indicated, a multidisciplinary approach is essential to educate the family about the risks and benefits of testing and improve their coping skills when the final diagnosis is made.

Radiofrequency ablation of hepatocellular carcinoma: pros and cons.  


Among locoregional treatments for hepatocellular carcinoma (HCC), radiofrequency ablation (RFA) has been accepted as the most popular alternative to curative transplantation or resection, and it shows an excellent local tumor control rate and acceptable morbidity. The benefits of RFA have been universally validated by the practice guidelines of international societies of hepatology. The main advantages of RFA include 1) it is minimally invasive with acceptable morbidity, 2) it enables excellent local tumor control, 3) it has promising long-term survival, and 4) it is a multimodal approach. Based on these pros, RFA will play an important role in managing the patient with early HCC (smaller than 3 cm with fewer than four tumors). The main limitations of current RFA technology in hepatic ablation include 1) limitation of ablation volume, 2) technically infeasible in some tumors due to conspicuity and dangerous location, and 3) the heat-sink effect. Many technical approaches have been introduced to overcome those limitations, including a novel guiding modality, use of artificial fluid or air, and combined treatment strategies. RFA will continue to play a role as a representative ablative modality in the management of HCC, even in the era of targeted agents. PMID:21103289

Pros and cons of peptide isolectric focusing in shotgun proteomics.  


In shotgun proteomics, protein mixtures are proteolytically digested before tandem mass spectrometry (MS/MS) analysis. Biological samples are generally characterized by a very high complexity, therefore a step of peptides fractionation before the MS analysis is essential. This passage reduces the sample complexity and increases its compatibility with the sampling performance of the instrument. Among all the existing approaches for peptide fractionation, isoelectric focusing has several peculiarities that are theoretically known but practically rarely exploited by the proteomics community. The main aim of this review is to draw the readers' attention to these unique qualities, which are not accessible with other common approaches, and that represent important tools to increase confidence in the identification of proteins and some post-translational modifications. The general characteristics of different methods to perform peptide isoelectric focusing with natural and artificial pH gradients, the existing instrumentation, and the informatics tools available for isoelectric point calculation are also critically described. Finally, we give some general conclusions on this strategy, underlying its principal limitations. PMID:23639126

Clinical drawbacks of total lymphoid irradiation: the cons  

SciTech Connect

Success has been reported with use of total lymphoid irradiation (TLI) in organ transplant recipients and in patients with rheumatoid arthritis and other autoimmune diseases. In a well-conducted randomized double blind clinical trial, Cook et al have found that TLI was superior to sham irradiation of patients with multiple sclerosis (MS). However, it is clear from looking at this data that not all patients responded to TLI and that with time disease activity returned. Our own experience with TLI in two MS patients was very disappointing. Despite its apparent benefit in some conditions, considerable drawbacks are associated with TLI. These include high financial cost, unpleasant treatment-related side effects, and the possibility that more serious morbidity as well as mortality may be treatment-related. Furthermore, the optimum therapeutic regimen for TLI has not yet been established. Issues related to cumulative dose, dose per fraction, frequency of fractions, field of irradiation, and interaction with other therapies still need clarification. For these reasons we do not recommend TLI as a treatment for MS.
