Abstract
Introduction: Gastric cancer is the fourth most common cancer and the second leading cause of cancer death worldwide. North of Iran is a high-risk area for gastric cancer. Nitric oxide (NO), mainly synthesized by inducible nitric oxide synthase (NOS2) in pathological conditions, plays an important role in cytotoxicity, inflammation and fibrosis. In this research we studied the effect of (rs1137933) T>C genotype on gastric cancer..
Methods: This analysis was performed on 93 patients with gastric cancer who were referred to endoscopy Tuba Clinic in 2015 and 93 healthy individuals as controls. DNA extracted from peripheral blood samples was applied in PCR-RFLP (Polymerase chain reaction- restriction fragment length polymorphism) analysis to determine (rs1137933) T>C genotype. The association of the (rs1137933) T>C genotype and gastric cancer risk were analyzed by MedCalc software and (X2) Chi-square and (OR) Odds Ratio exams.
Results: Frequency of TT, CT, and CC genotypes in cases was 12.61, 51.35 and 36% and 38.7, 34.4, and 26.8% in the control group. Significant association was found between (rs1137933) T>C genotype with gastric cancer chance, P<0.05, OR=2/04, 95% CI (1/37 to 3/03).
Conclusion: The results of the study show that the presence of CC+CT genotypes may increase the risk of gastric cancer. P < 0.0001, OR=4.37 (2.17 to 8.80).Therefore, investigating the (rs1137933) T>C single nucleotide polymorphism of NOS2 gene could be an appropriate molecular marker that could be used to determine individual sensitivity to gastric cancer and for designing cancer prevention programs.

Abstract
Introduction: Due to significant social, economic, cultural, and lifestyle changes in Iran during past decades and the relationship among the unstable social and economic status and mental complications the study of psychiatric disorders has become important and necessary, the aim of this study was epidemiology of psychiatric disorders in children and adolescents.
Methods: A total of 1035 children aged 6-18 years from Yazd Province, Iran were enrolled in this cross-sectional study in 2017 using a multistage cluster sampling method. Data were collected using the following inventories for school-age children (6-18 years): Kiddie-SADS-Present and Lifetime Version (K-SAD-SPL). Logistic regression and SPSS version 16 software were used for data analysis.
Results: 44.1% of participants were boys and 55.9% were girls. The mean age of the participants was 11.3±3.9 years. The prevalence of psychiatric disorders in children and adolescents was 35.5%. Meanwhile, anxiety disorders had the highest prevalence rate (22.2%) and among anxiety disorders, separation anxiety disorder (8.7%) and generalized anxiety (8.6%) were the most prevalent. There was a significant difference in all psychiatric disorders based on gender, more evident in the high rate of obsessive-compulsive disorder, enuresis, tic, attention deficit hyperactivity disorder, hyperactivity, oppositional defiant disorder, conduct disorder, smoking disorder, and epilepsy were more evident in boys (P-value < 0.05).
Conclusion: The prevalence rate of psychiatric disorders in young population of Yazd Province is relatively high and because of its impact on individuals' social and personal function, it could have substantial implications for mental health services.
