ter, Tehran University of Medical Sciences.Objective This study aimed to model risky driving and predict its occurrence according to the constructs of personality organization and mentalization considering the role of aggressive driving as a mediator construct. Method A total of 428 individuals (219 men and 209 women) were selected using convenience sampling. The participants completed self-report questionnaires on aggressive driving, risky driving, mentalization and personality organization Also, data were analyzed using structural equating model and weighted regression. Results The results of this study showed a goof fit of the proposed structural model for predicting risky driving after some modifications (CFI = 0.95, RMSEA = 0.09). According to the results of regression weights, personality organization (regression weighted 0.044) and aggressive driving (regression weighted 0.98) were the strongest and mentalization (regression weighted 0.004) was the weakest predictor of risky driving. Aggressive driving was the strongest direct predictor and personality organization the strongest indirect predictor of risky driving. Conclusion Risky driving is a function of direct and indirect personal factors. Moreover, emotional factors have a direct effect on risky driving and more substantial constructs, such as personality, have an indirect effect on risky driving.

It is a complex disease and is approximately 80% inherited. One of the candidate genes in schizophrenia is transcription factor 4 (TCF4), which is positioned on chromosome 18 and is a transcription factor that plays a role in the transcription of Neurexin 1(NRXN1) gene, which is one of the candidate genes for developing schizophrenia. This case-control study aimed to investigate the correlation of TCF4 rs13381800 and NRXN1 rs17039988 polymorphisms with the risk of schizophrenia in a sample of Iranian patients with schizophrenia. Method A total of 200 individuals were included in this study 100 patients with schizophrenia (65 males and 35 females), with the mean age of 40.80 ± 11.298 years, and 100 as a control group (63 males and 37 females), with the mean age 32.92 ± 7.391 years. Allele specific polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) were done, respectively, for genotyping of rs13381800 (T/C) and rs17039988 (A/C) polymorphisms. Results The results showed that the frequency of C / C genotype in rs13381800 in patients' group was 9%, while it was 13% in the control group. Also, the frequency of C / C genotype in rs17039988 was 9% in patients and 7% in control groups. Statistical analysis of polymorphisms showed no correlation between patients and controls in rs13381800 (OR = 1.51; CI = 95%; P = 0.366) and rs17039988 (OR = 0.76; CI = 95%; P = 0.602). Conclusion No significant difference was found between rs13381800 and rs17039988 genotypes between patients and control groups in terms of gender, age and education in the patients group. Our study suggests that there was no correlation between desired polymorphisms with schizophrenia in the studied population.

This study aimed to explore the status of body mass index (BMI) in different psychiatric disorders in a national survey among children and adolescents and to identify the role of gender in this regard. Method A total of 30 532 children and adolescents were randomly selected using cluster sampling method with equal blocks of three age groups and two genders. Psychiatric disorders were assessed using a standardized face-to-face diagnostic interview of Kiddie Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version (KSADS-PL), and Body Mass Index (BMI) was measured for each participant. Results In this study, 22 730 children and adolescents (109 46 boys and 11784 girls), with valid data of BMI, completed the KSADS-PL interview. The prevalence of psychiatric disorders was 21.2% among underweight participants, 22.8% among overweight participants, and 22.2% among obese participants, which was significantlright © Psychiatry & Psychology Research Center, Tehran University of Medical Sciences.Background Between 40,000-70,000 people die yearly of rabies, an incurable disease. Besides post-bite vaccination, no treatment is available for it. HSP27inhibitorJ2 Methods First, virus dilution for antiviral effects in mice was determined. Then, animals were treated as follows control (NaCl 250 µL/animal/day); bufotenine (0.63, 1.05 and 2.1 mg in 250 µL of NaCl/animal/day); rabies (10-6,82CVS dilution); and test (10-6,82 CVS dilution and bufotenine, in the above-mentioned doses). Animals were observed daily for 21 days or until the 3rd stage of rabies infection. Twitch-tension and liposome studies were applied to understand the possible interaction of bufotenine with receptors, particularly acetylcholine. Results Bufotenine was able to increase the survival rate of intracerebrally virus-infected mice from 15 to 40%. Bufotenine did not seem to interfere with the acetylcholine response in the skeletal muscle, indicating that its mechanism of action is not blocking the virus entrance due to nAChR antagonism. By analyzing liposomes, we could observe that bufotenine did not passively penetrates cell membranes, indicating the necessity of complementary structures to cell penetration. Conclusions Bufotenine is a promising candidate for drug development. After further chemical modification, it might be possible to dissociate minor side effects, increase efficiency, efficacy and pharmacokinetics, yielding a true anti-rabies drug.INTRODUCTION This study aimed to evaluate the association between smoking and smoking index with clinical outcomes of esophageal squamous cell carcinoma patients. METHODS This is a retrospective analysis conducted on consecutive patients with esophageal carcinoma who underwent esophagectomy from January 2005 to December 2010. All patients had pathologically confirmed esophageal squamous cell carcinoma. The association between smoking and sociodemographic characteristics with overall survival and disease-free survival was analyzed. Serum carcinoembryonic antigen was measured using an electrochemiluminescence immunoassay. RESULTS A total of 944 patients were enrolled. Kaplan-Meier analysis indicated that esophageal squamous cell carcinoma patients who smoked had a significantly worse prognosis in terms of both overall survival (p=0.007) and disease-free survival (p= 0.010). Multivariate analysis demonstrated that age (p=0.001), carcinoembryonic antigen (p=0.012), tumor-node-metastasis (TNM) staging (p less then 0.
