although genetic variants that affect susceptibility to coronary artery disease (cad) have been greatly known, a number of these single nucleotide polymorphisms (snps) remain to be analyzed in populations with different ethnicities. cad is influenced by numerous genetic, environmental, and lifestyle factors, and is an important reason for mortality around the globe. in this study, a novel snp (...
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...
introduction: a thyroid nodule is a palpable swelling in a thyroid gland with an otherwise normal appearance. palpable thyroid nodules occur in 4 to 7 percent of the population. nodular thyroid diseases are more frequent in women than in men. most actions of thyroid hormone are mediated by the active form of thyroid hormone. d2 is essential for formation of active hormone of t3 through deiodina...
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 ...
aim : the present study evaluated the association between g241r and k469e polymorphisms of intercellular adhesion molecule 1 gene and inflammatory bowel disease in iranian population. background : inflammatory bowel disease including ulcerative colitis and crohn’s disease, is a chronic idiopathic inflammatory disease of the gastrointestinal tract. there are two single base polymorphisms of in...
