background:diabetic retinopathy (dr) is a sight-threatening microvascular complication of diabetes in which the vascular endothelium is damaged due to oxidative stress and inflammation, and vitreous vegf concentration becomes elevated. the aim of the present study was to assess the association of dr with genetic variations of the mnsod, a major antioxidant enzyme, and vegf, an important mediato...

background: sarcoidosis is a multisystem inflammatory disease of unknown origin with characterization of small granulomas. angiotensin-converting enzyme (ace) is a pathophysiologic marker of sarcoidosis. we present the ace insertion/deletion (i/d) polymorphism in correlation with serum ace level in iranian patients with sarcoidosis. methods: from jan 2014 to jan 2015, 102 iranian patients who h...

introduction reelin gene (reln) codes a large extracellular matrix glycoprotein with serine protease activity and is implicated in the modulation of neuronal signaling, synaptic transmission and plasticity. the reelin plays a fundamental and pivotal role in the development of laminar structures and may be one of the loci contributing to the positive linkage between chromosome 7q and autistic di...

the present  study  was carried out to investigate the polymorphism of intron 3 to exon 3 of prolactin gene containing 24 bpindel at nucleotide position (np)  358 and its association with some reproductive traits in japanese quail. these traits consisted of weight (wsm) and age at sexual maturity (asm), mean egg weight at 2nd, 4th, 6th, and 2-6th weeks (mew), and the number of eggs during the 2...

objective: jaundice with indirect hyperbilirubinemia is one of the most common neonatal problems that occur in 60% of term and 80% of preterm neonates but the causes are mostly unknown. it is suggested that race plays an important role in the prevalence of hyperbilirubinemia. it is a common problem in iran that worries both parents and pediatricians. it has been found that a mutation in the ugt...

abstract background: schizophrenia is a severe mental disorder and numerous genes and loci are beleived to be involved in this disease. recent studies have reported a strong genetic association between dtnbp1 (dystrobrevin-binding protein 1) gene variants and schizophrenia. methods: in this research, we used a case-control study to establish the possible association between the p1635 (rs3213207...

the real pathophysiology of crohn’s disease is unknown. the higher prevalence of crohn’s disease in caucasian and jewish ethnicities, as well as its familial aggregation and higher concordance among monozygotic twins, suggest some roles for genes in its development, clinical progression, and outcome. recent original studies have indicated dlg5113g/a gene polymorphism as a risk factor for crohn’...

background: one of the limitations in the treatment of common diseases such as cancer chemotherapy is development of multidrug re sistance (mdr). polymorphisms could alter the expression level of mdr1 gene, which plays an important role in mdr. in this research, the frequency of c3435t, c1236t, and g2677t/a polymorphisms of mdr1 gene was investigated in a large group of population from hamadan ...
