Aims: In this study, we investigated serumβ-endorphin and its feedback system in women with polycystic ovary syndrome (PCO). Experimental and clinical studies show that there is an over activity of sympathetic nervous system in PCOS. It affects quality of life and can worsen anxiety and depression either due to the features of PCOS or due to the diagnosis of a chronic disease. Study Area and Duration of Study: This study was carried out at Vali-e-Asr Clinic, a Reproductive Health Research Center, affiliated to Tehran University of Medical Sciences between February 2012 and April 2013. Methodology: 77 women with PCO were studied with diagnose criteria and within the age range of 20-40 years without special disease. Stress neurohormones, beta-endorphine and melatonin serum levels were measured in study group and were compared with healthy women as control group. A questionnaire with items related to pieces of information about stress was used for data collection. Stress symptoms were assessed using the Understanding Yourself questionnaire. Statistical analyses were performed using SPSS Ver. 13.0 (SPSS Inc., Chicago, ILL, USA). The data are Original Research Article Zangeneh et al.; ARRB, 5(5): 409-418, 2015; Article no.ARRB.2015.044 410 presented as mean ± SD or as frequency with percentages. A p-value less than 0.05 were considered as statistically significant. Results: Data of serum levels of neurohormones showed, beta endorphin decreased (P

Polycystic ovary syndrome (PCOS) affects quality of life and can worsen anxiety and depression either due to the features of PCOS or due to the diagnosis of a chronic disease. Corticotrophin-releasing hormone (CRH) and nerves growth factor (NGF) are the modulator for the actions of the sympathetic nervous and immune systems.In total, 171 women divided into two groups: study and control groups. Serum CRH, NGF, and interleukins: IL-1α. IL-1β, 17A, and TNFα were determined by ELISA Kits in both groups.The results showed that IL-1α (p 0.001) and β (p = 0.017) significantly increased in PCO group. CRH, NGF, and IL-17α in serum of patients with PCO significantly lower than the control group (p 0.001). The results of this study indicate: (1) destruction of three cytokines pattern, (2) Reduction of CRH, NGF, and IL-17α in serum of PCO patients can be under the direct influence of the sympathetic nervous system (SAS), and (3) reduction of CRH and NGFα can be reason of psych/emotional distress in women with PCOS.The results of this study confirm (1) low-grade chronic inflammation in PCOS. This impaired cytokine pattern can play a major role in the immune-pathogenesis of PCOS; (2) hyponeurotrophinemia and reduction of CRH in women with PCOS could reflect deficit of neuronal stress-adaptation in these patients.

The molecular genotyping of individuals and reconstruction of kinship through short and highly polymorphic DNA markers, so called short tandem repeats (STR), has become one of the important and efficient methods in anthropology studies and forensic science. Although many populations have been analyzed, no study has yet been carried out on Sadat populations who are putative descendents of Prophet Mohammad (peace be upon him). Polymorphisms of 6 Y-STR loci (DYS19, DYS385a/b, DYS389II, DYS390, DYS392, and DYS393) have been studied in an unrelated population of Sadat males. The aim of this study was to find possible similarities within Sadat males, resided in Iran. Among Sadat, DYS385b was proved to be the most polymorphic (GD = 0.8588), and DYS392 showed the lowest polymorphism (GD = 0.3527). In 50 samples, 45 different haplotypes were found, of which 39 haplotypes were unique. In the study, three samples had multi-allelic patterns. Haplotype diversity, in regard to these 7 markers was 0.9942.

- Abstract
The illuminating picture of genetic mechanisms underlying the development of type 2 diabetes (T2DM) includes differently accumulated genetic polymorphisms that increase the risk along with environmental factors. A number of single nucleotide polymorphisms (SNPs) are indicated to be linked with T2DM, but also conflicting results have been found. To examine the contribution of these polymorphisms in conferring susceptibility to T2DM, the association of HHEX rs1111875A/G and CDKN2A/B rs10811661C/T common gene polymorphisms with the risk of T2DM in an Iranian population was evaluated. In this study participated 140 patients and 140 controls. Genomic DNA was extracted from samples and genotyping of the polymorphisms was performed by the Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) technique. A significant association was found with the G allele (OR = 1.729, CI = 1.184-2.523, P = 0.004) and GG genotype (OR = 2.921, 95% CI = 1.789-4.771, P0.001) of the rs1111875A/G SNP for susceptibility to T2DM in the recessive model. Furthermore, compared with the GG genotype, individuals with the GA genotype had a lower risk to develop T2DM (OR = 0.237, 95% CI = 0.137-0.408, P0.001) in the additive model. In addition, an association between the polymorphism and BMI in regard to the risk of T2DM was identified. The genotype and allele frequencies of the rs10811661C/T polymorphism did not show a statistically significant association with T2DM in any genetic model. Our results show that the rs1111875A/G polymorphism is an important susceptibility polymorphism for the development of T2DM in the Iranian population. Also, these findings support that this polymorphism is a key genetic risk factor for the development of T2DM in multiple ethnic populations.
