Predicting course of illness in patients with severe obsessive-compulsive disorder.

OBJECTIVE Few data are available to inform clinical expectations about course and prognosis of severe obsessive-compulsive disorder (OCD). Such information is necessary to guide clinicians and to inform criteria for invasive interventions for severe and intractable OCD. This study sought to examine course and prospective predictors of a chronic course in patients with severe OCD over 5 years. METHOD A selected subset of adults in the Brown Longitudinal Obsessive-Compulsive Study (BLOCS) was included. Adult BLOCS participants were enrolled between 2001 and 2006. All participants in the current study (N = 113) had DSM-IV OCD diagnosis, severe OCD symptoms at baseline, and at least 1 year of follow-up data. RESULTS Cox proportional hazard models were used to examine the general pattern of course in the severe OCD sample based on Longitudinal Interval Follow-Up Evaluation (LIFE) psychiatric status ratings, as well as test predictors of chronically severe course. Results indicated that approximately half of patients with severe OCD at baseline had illness drop to a moderate or lower range of severity during 5 years of follow-up (50.4%) and that marked improvement was rare after 3 years of severe illness. The only unique predictor of a more chronically severe course was patient report of ever having been housebound for a week or more due to OCD symptoms (P < .05). CONCLUSIONS Findings of this study were 3-fold: (1) half of participants with severe OCD have symptom improvement over 5 years of follow-up, (2) the majority of participants that drop out of the severe range of symptom severity do so within the first 3 years of follow-up, and (3) patient-reported history of being housebound for 1 week or more due to OCD is a significant predictor of OCD's remaining severe over the 5-year follow-up.
Estrogen and Progestin Binding in Cytosols of Ovarian Adenocarcinomas

Because a few ovarian adenocarcinomas respond favorably to endocrine therapy, we tested the hypothesis that some ovarian adenocarcinomas have functional similarity with sex-hormone-sensitive endometrial and breast tumors. Cytosols from 23 ovarian adenocarcinomas and 27 control tissues were examined for receptorlike estrogen and/or progestin binding. Eight of 16 primary ovarian adenocarcinomas had estrogen and/or progestin receptorlike components; among the metastases tested, one third retained estrogen binding. No correlations were found between binding characteristics and histopathologic grade. The presence of estrogen binding in a lung lesion helped confirm recurrent ovarian disease. Estrogen binding occurred in specimens from women with no histories of exposure to exogenous estrogen. Because tamoxifen and nafoxidine could inhibit estradiol binding, it is likely that anti-estrogens will prove beneficial against some ovarian cancers.
Aortic endothelial cells synthesize basic fibroblast growth factor which remains cell associated and platelet‐derived growth factor‐like protein which is secreted

Cultured bovine aortic endothelial cells synthesize growth factors which markedly differ in the regulation of their storage and secretion. Endothelial cell lysates, but not conditioned medium, contain a growth factor activity that appears to be basic fibroblast growth factor (FGF) by the following criteria: (1) it elutes from heparin‐Sepharose at 1.4–1.6 M NaCl; (2) it is mitogenic for bovine aortic and capillary endothelial cells; (3) it is heat sensitive but stable to dithiothreitol; (4) it has a molecular weight of about 18,000 daltons; and (5) it cross‐reacts with antiserum directed against basic FGF. In contrast, endothelial cell conditioned medium, but not lysates, contains a growth factor activity that (1) elutes from heparin‐Sepharose at 0.4 – 0.5 M NaCl; (2) is mitogenic for fibroblasts and vascular smooth muscle cells but not for capillary endothelial cells; (3) is heat stable and dithiothreitol sensitive; and (4) competes with platelet‐derived growth factor (PDGF) for binding to fibroblasts. From these criteria, it appears that endothelial cells secrete into the medium growth factors some of which are PDGF‐like, but secrete little if any basic FGF. It is suggested that endothelial cell‐associated basic FGF acts in an autocrine fashion to stimulate endothelial cell proliferation in response to endothelial cell perturbation or injury. On the other hand, the endothelial cell‐secreted growth factors which are smooth muscle cell but not endothelial cell mitogens might exert a paracrine function on neighboring cells of the vessel wall.
Vybrané teorie migrace a jejich význam při vytváření migračních politik

This paper is a survey of selected theoretical approaches to migration. It focuses on their practical application when creating new or adjusting existing migration policy concepts. The aim is to seek the possible leverages offering the possibility to influence migration flows not only by the receiving countries, but also by the sending countries. Secondary attention is paid to the interconnection of labour and capital, seeking the answer to the question whether FDI and migration flows are indeed supplementary processes. The paper examines a whole range of theoretical approaches, starting from the simpler ones (gravitational models), and continuing with the more elaborate approaches (neoclassical, behavioural), including the latest approaches in migration theory.
Clinical and radiographic evaluation of Nano-crystalline hydroxyapatite bone graft (Sybograf®) in combination with bioresorbable collagen membrane (Periocol®) in periodontal intrabony defects

Background: Nanosized ceramics may represent a promising class of bone graft substitutes due to their improved osseointegrative properties. Nanocrystalline Hydroxyapatite (NcHA) bind to bone and stimulate bone healing by stimulation of osteoblast activity. The present study aims to explore the clinical and radiographical outcome of NcHA bonegraft (Sybograf®) with collagen membrane (Periocol®), in comparison with open flap debridement (OFD), in the treatment of intrabony periodontal defects. Materials and Methods: A parallel-group, randomized, controlled clinical trial was designed to conduct the study. Eighteen intrabony defects in 14 systemically healthy patients aged between 25 to 65 years were randomly assigned to test and control group. The plaque index, gingival index, probing pocket depth (PPD), clinical attachment level (CAL), and gingival recession (REC) were recorded at baseline, and were reevaluated at 6 months. In addition to this, radiographic bone fill was assessed using digital software. At the test site, NcHA bone graft and collagen membrane was placed, whereas at the control site, only OFD was done. Recall appointments were made at 7 days, 30 days, and then at 3 months and 6 months. Results: The data were subjected to statistical analysis using the Mann-Whitney ‘U’ Test and Wilcoxon signed rank sum test. In the control group, the mean reduction of PPD was 3.22±1.09 mm (P=0.007) and CAL gain was 2.77±1.09 mm (P=0.007). In the test group, the mean PPD reduction of 4.33±0.5 mm (P=0.006) and mean gain in CAL was 3.77±0.66 mm (P=0.006) at 6 months. The mean increase in REC was 0.55±0.72 mm (P=0.025) in test, and 0.44±0.52 mm (P=0.046) in control group. The mean gain in radiographic defect fill was 2.07±0.67 mm (P=0.008) in test and 0.91±0.21 mm (P=0.007) in control group. Conclusion: The nanocrystalline hydroxyapatite bone graft in combination with collagen membrane demonstrated clinical advantages beyond that achieved by OFD alone.
Relationships between stem diameter, sapwood area, leaf area and transpiration in a young mountain ash forest.

We examined relationships between stem diameter, sapwood area, leaf area and transpiration in a 15-year-old mountain ash (Eucalyptus regnans F. Muell.) forest containing silver wattle (Acacia dealbata Link.) as a suppressed overstory species and mountain hickory (Acacia frigescens J.H. Willis) as an understory species. Stem diameter explained 93% of the variation in leaf area, 96% of the variation in sapwood area and 88% of the variation in mean daily spring transpiration in 19 mountain ash trees. In seven silver wattle trees, stem diameter explained 87% of the variation in sapwood area but was a poor predictor of the other variables. When transpiration measurements from individual trees were scaled up to a plot basis, using stem diameter values for 164 mountain ash trees and 124 silver wattle trees, mean daily spring transpiration rates of the two species were 2.3 and 0.6 mm day(-1), respectively. The leaf area index of the plot was estimated directly by destructive sampling, and indirectly with an LAI-2000 plant canopy analyzer and by hemispherical canopy photography. All three methods gave similar results.
Gender and interindividual variability in pharmacokinetics

Like any other drugs, antiallergic medications can be associated with large inter- and intraindividual variability in their disposition. The best-documented examples belong to the H1 antihistamines. Variable drugs are more likely to show unpredictable therapeutic response with both increased risks of side effects and subtherapeutic dosing in individual subjects. This article will review the main factors contributing to intervariability in pharmacokinetics with a special emphasis on gender differences, genetic polymorphism, and food habits.
Glucocorticoid receptors in the basolateral nucleus of amygdala are required for postreactivation reconsolidation of auditory fear memory

It is well known that initial consolidation requires de novo gene transcription and protein synthesis in order for memory to become stable. The consolidated memory again becomes labile and temporarily sensitive to disruption when retrieved, requiring a reconsolidation process to become permanent. Although it is well established that glucocorticoid receptors (GR) in the basolateral nucleus of amygdala (BLA) are required for consolidation of fear memory, little is known about their role in reconsolidation of fear memory. In the present study, we first examined the effect of a GR antagonist on postconditioning consolidation of auditory fear memory (AFM). Intra‐BLA infusion of the GR antagonist RU486 0 h postconditioning impaired long‐term AFM, leaving short‐term AFM intact. RU486 had no effect if infusion was performed 6 h postconditioning. We then investigated the effect of the RU486 treatment on postretrieval reconsolidation of AFM. Severe amnesia took place when RU486 was infused into the BLA 0 h postretrieval (reactivation) of AFM, regardless of whether the retrieval was performed 1 day or 10 days postconditioning. RU486 produced no amnesia if the memory retrieval was omitted or if the drug was administered 6 h postretrieval. Treatment with RU486 0 h postretrieval produced no deficit in postretrieval short‐term memory but impaired postretrieval long‐term memory, and the amnesia exhibited no spontaneous recovery 6 days after retrieval. The present results provide strong evidence that glucocorticoid receptors in the BLA are required for reconsolidation as well as consolidation of AFM.
Model-Driven Software Migration: A Methodology - Reengineering, Recovery and Modernization of Legacy Systems

Today, reliable software systems are the basis of any business or company. The continuous further development of those systems is the central component in software evolution. It requires a huge amount of time- man power- as well as financial resources. The challenges are size, seniority and heterogeneity of those software systems. Christian Wagner addresses software evolution: the inherent problems and uncertainties in the process. He presents a model-driven method which leads to a synchronization between source code and design. As a result the model layer will be the central part in further evolution and source code becomes a by-product. For the first time a model-driven procedure for maintenance and migration of software systems is described. The procedure is composed of a model-driven reengineering and a model-driven migration phase. The application and effectiveness of the procedure are confirmed with a reference implementation applied to four exemplary systems.
Synthesis, biological evaluation, and enzyme docking simulations of 1,5-diarylpyrrole-3-alkoxyethyl ethers as selective cyclooxygenase-2 inhibitors endowed with anti-inflammatory and antinociceptive activity.

A series of substituted 1,5-diarylpyrrole-3-alkoxyethyl ethers (6, 7, and 8) has been synthesized with the aim to assess if in the previously reported 1,5-diarylpyrrole derivatives (5) the replacement of the acetic ester moiety with an alkoxyethyl group still led to new, highly selective and potent COX-2 inhibitors. In the in vitro cell culture assay, all the compounds proved to be potent and selective COX-2 inhibitors. In the human whole blood (HWB) assay, compound 8a had a comparable COX-2 selectivity to valdecoxib, while it was more selective than celecoxib but less selective than rofecoxib. The potential anti-inflammatory and antinociceptive activities of compounds 7a, 8a, and 8d were evaluated in vivo, where they showed a very good activity against both carrageenan-induced hyperalgesia and edema in the rat paw test. In the abdominal constriction test compound 7a, 8a, and 8d were able to reduce the number of writhes in a statistically significant manner. Furthermore, the affinity data of these compounds have been rationalized through enzyme docking simulations in terms of interactions with a crystallographic model of the COX-2 binding site by means of the software package Autodock 3.0. 5, GRID 21, and MacroModel 8.5 using the complex between COX-2 and SC-558 (1b), refined at a 3 A resolution (Brookhaven Protein Data Bank entry: 6cox ).
Evolution of ossification sequences in salamanders and urodele origins assessed through event‐pairing and new methods

SUMMARY Ossification sequences of the skull in extant Urodela and in Permo‐Carboniferous Branchiosauridae have already been used to study the origin of lissamphibians. But most of these studies did not consider some recent methods developed to analyze the developmental sequences within a phylogenetic framework. Here, we analyze the ossification sequences of 24 cranial bones of 23 extant species of salamanders using the event‐pairing method. This reveals new developmental synapomorphies for several extant salamander taxa and ancestral sequences for Urodela under four alternative reference phylogenies. An analysis with the 12 bones for which ossification sequence data are available in urodeles and in the branchiosaurid Apateon is also performed in order to compare the ancestral condition of the crown‐group of Urodela to the sequence of Apateon. This reveals far more incompatibilities than previously suggested. The similarities observed between some extant salamanders and branchiosaurids may result from extensive homoplasy, as the extreme variation observed in extant Urodela suggests, or be plesiomorphic, as the conservation of some ossification patterns observed in other remotely related vertebrates like actinopterygians suggests. We propose a new, simpler method based on squared‐change optimization to estimate the relative timing of ossification of various bones of hypothetical ancestors, and use independent‐contrasts analysis to estimate the confidence intervals around these times. Our results show that the uncertainty of the ancestral ossification sequence of Urodela is much greater than event‐pairing suggests. The developmental data do not allow to conclude that branchiosaurids are closely related to salamanders and their limited taxonomic distribution in Paleozoic taxa precludes testing hypotheses about lissamphibian origins. This is true regardless of the analytical method used (event‐pairing or our new method based on squared‐change parsimony). Simulations show that the new analytical method is generally more powerful to detect evolutionary shifts in developmental timing, and has lower Type I error rate than event‐pairing. It also makes fewer errors in ancestral character value or state assignment than event‐pairing.
Epidemiology/risk factors of sexual dysfunction.

INTRODUCTION Accurate estimates of prevalence/incidence are important in understanding the true burden of male and female sexual dysfunction and in identifying risk factors for prevention efforts. AIM To provide recommendations/guidelines concerning state-of-the-art knowledge for the epidemiology/risk factors of sexual dysfunctions in men and women. METHODS An International Consultation in collaboration with the major urology and sexual medicine associations assembled over 200 multidisciplinary experts from 60 countries into 17 committees. Committee members established specific objectives and scopes for various male and female sexual medicine topics. The recommendations concerning state-of-the-art knowledge in the respective sexual medicine topic represent the opinion of experts from five continents developed in a process over a 2-year period. Concerning the Epidemiology/Risk Factors Committee, there were seven experts from four countries. MAIN OUTCOME MEASURE Expert opinion was based on grading of evidence-based medical literature, widespread internal committee discussion, public presentation and debate. RESULTS Standard definitions of male and female sexual dysfunctions are needed. The incidence rate for erectile dysfunction is 25-30 cases per thousand person years and increases with age. There are no parallel data for women's sexual dysfunctions. The prevalence of sexual dysfunction increases as men and women age; about 40-45% of adult women and 20-30% of adult men have at least one manifest sexual dysfunction. Common risk factor categories associated with sexual dysfunction exist for men and women including: individual general health status, diabetes mellitus, cardiovascular disease, other genitourinary disease, psychiatric/psychological disorders, other chronic diseases, and socio-demographic conditions. Endothelial dysfunction is a condition present in many cases of erectile dysfunction and there are common etiological pathways for other vascular disease states. Increasing physical activity lowers incidence of ED in males who initiate follow-up in their middle ages. CONCLUSIONS There is a need for more epidemiologic research in male and female sexual dysfunction.
Outbreak of travel-related pontiac fever among hotel guests illustrating the need for better diagnostic tests.

BACKGROUND Pontiac fever (PF), a legionellosis with influenza-like symptoms and high attack rates, is rarely reported. Travel-related outbreaks can elude detection because infected persons are often widely removed geographically from the transmission source before illness onset. Thirty-one persons staying at an Illinois hotel during August 9 to 11, 2002, reported influenza-like symptoms to local health departments within 24 to 48 hours of checkout. We investigated to identify the cause and source of illness to guide control measures. METHODS Hotel water samples were collected for culture. A telephone questionnaire detailing illness symptoms and exposures was administered to all who were guests at the hotel from August 9 to 15 (n = 380). A case was defined as onset of fever, headache, and myalgia in a guest in the 14 days following the hotel stay. Patient sera were tested by hemagglutination assay for antibodies to Legionella species. RESULTS Among 204 questionnaire respondents from 15 states and Canada, 50 met the case definition. Among persons exposed to the swimming pool/whirlpool spa area, 63% (47 of 75) became ill versus 3% (3 of 110) of unexposed persons (relative risk 23.0, 95% CI 7.4-71.1). Illness risk increased with increasing time exposed to the pool/spa. Approximately 95 to 115 bathers per day, two to three times above the usual number, used the spa during August 9 to 11. Three Legionella species, L. dumoffii, L. maceachernii, and L. micdadei, were isolated from spa filter backwash cultures. Two of 15 ill persons with acute- and convalescent-phase sera had a greater than fourfold rise in antibody titer to L. micdadei. CONCLUSIONS PF was associated with exposure to a hotel pool/spa area. Heavy bather usage likely contributed to a decreased effectiveness of the disinfectant in the whirlpool spa, possibly promoting bacterial aerosolization. Linking case information from many states is essential in identifying and eliminating the source of disease transmission in travel-related outbreaks of PF. Clinicians should be aware of PF in the differential diagnosis of patients with influenza-like symptoms following recent travel, particularly with exposure to a communal-use whirlpool spa.
Stage-Specific Transcription of Distinct Repertoires of a Multigene Family During Plasmodium Life Cycle

Members of a multigene family in the rodent malaria parasite Plasmodium yoelii yoelii code for 235-kilodalton proteins (Py235) that are located in the merozoite apical complex, are implicated in virulence, and may determine red blood cell specificity. We show that distinct subsets of py235 genes are expressed in sporozoites and hepatic and erythrocytic stages. Antibodies to Py235 inhibited sporozoite invasion of hepatocytes. The switch in expression profile occurred immediately after transition from one stage to another. The results suggest that this differential expression is driven by strong biological requirements and provide evidence that hepatic and erythrocytic merozoites differ.
Potentially Harmful Therapy and Multicultural Counseling

In recent years, psychologists have been increasingly concerned about potentially harmful therapy (PHT), yet this recent discourse has not addressed issues that have long been voiced by the multicultural counseling and psychotherapy movement. We aim to begin to bring these seemingly disparate discourses of harm into greater conversation with one another, in the service of placing the discipline on a firmer foothold in its considerations of PHT. After reviewing the two discourses and exploring reasons for their divergence, we argue that they operate according to differing assumptions pertaining to the sources, objects, and scope of harm. We then argue that these differences reveal the discipline’s need to better appreciate that harm is a social construct, that psychotherapy may be inherently ethnocentric, and that strategies for collecting evidence of harm should be integrated with a social justice agenda.
A common CYP1B1 polymorphism is associated with 2-OHE1/16-OHE1 urinary estrone ratio

Abstract Cytochrome P450 (CYP) is a multigene family of enzymes involved in important life functions; some of these genes are inducible and are implicated in the oxidative metabolic activation and detoxification of many endogenous and exogenous compounds. CYP1B1 codes for an enzyme that catalyses the production of a 2- and 4-hydroxyl group in estrone and estradiol, while CYP1A1 catalyzes the 2-hydroxylation of estradiol in endometrium. The two genes were evaluated in a cohort of 150 subjects: African-American women had significantly lower 2-hydroxyl estrone/16-hydroxyl estrone (2-OHE1/16-OHE1) urinary metabolite ratios than Caucasian women (2.06±1.05 vs. 1.43±0.56; p=0.0002). A common polymorphism in the CYP1B1 gene (leucine to valineat codon 432) was associated with changes in urinary estrogen levels: both Caucasian and African-American women carrying the variant allele showed higher urinary metabolite ratios than women with the wild-type allele. No effect of the CYP1A1 MspI was observed. The 4-OHE1/2-OHE1 ratio was lower in subjects carrying the variant allele (Leu). The percentage change in 2-OHE1/16-OHE1 urinary ratio after indole treatment was significant in both Caucasian and African-American women carrying the wild-type CYP1B1 genotype, although it was more evident in African-Americans than in Caucasians. These results suggest that the Leu/Val CYP1B1 polymorphism may modify estradiol metabolism.
