background attention deficit hyperactivity disorder (adhd) is a multi-factorial disorder that has defined by hyperactivity, impulsivity and attention deficits. various neurotransmitters such as dopamine can play a role in its pathophysiology. the aim of this study was to examine the association of two common single nucleotide polymorphisms in drd2 gene, taq i a (t/c) and taq i b (g/a), with adh...

background: the sry gene (sry) provides instructions for making a transcription factor called the sex-determining region y protein. the sex-determining region y protein causes a fetus to develop as a male. in this study, sry of 15 spices included of human, chimpanzee, dog, pig, rat, cattle, buffalo, goat, sheep, horse, zebra, frog, urial, dolphin and killer whale were used for determine of bioi...

background: the multifunctional transforming growth factor beta (tgf-β) is a glycoprotein that exists in three isoforms. tgf-β3 expression increases in fetal wound healing and reduces fibronectin and collagen i and iii deposition, and also improves the architecture of the neodermis which is a combination of blood vessels and connective tissue during wound healing. fibroblasts are key cells in t...

quantitative traits locus for milk production traits has been described on centromeric end of bovine chromosome 14. reports name the acyl coa: diacylglycerol acyltransferase (dgat1) gene as a potential candidate gene with dinucleotide substitution (aa to gc) in exon viii which causes the change of lysine to alanine in amino acid (k232a).the aim of the present study was to estimate the frequency...

the fecb, a mutation in the bone morphogenetic protein receptor ib (bmpr-ib) gene, which increases the fecundity of booroola merino sheep, and fecgh, a mutation in the growth and differentiation factor 9 (gdf9), which affects the fecundity of cambridge and belclare sheep in a dose sensitive manner, were analyzed as candidate genes associated with the prolificacy in rayini goats. these polymorph...

objective: identity the genetic aspects and major gene influence on energy balance, milk production, fertility, food safety and consumer are the recent interests of genetic and breeding researchers. methods: najdi cattle is the most prominent breeds in khuzestan province. to do this plan in shoushtar najdi cattle station, blood samples were taken from 15 najdi cattles. dna was extracted from wh...

conclusions this finding may help improve early detection, differential diagnosis, genetic counseling, and even treatment of patients with pku. introduction phenylketonuria (pku) is an autosomal recessive inborn error of phenylalanine metabolism, which is caused by mutation in phenylalanine hydroxylase (pah) gene. most of the pah mutations are missense mutations (67%), which are followed by sma...

abstract tuberculosis and diabetes mellitus are the most important reasons in mortality all over the world. it’s clear that reviewing of relationship between tuberculosis (tb) and diabetes mellitus (dm) is necessary; on the other hand it’s found that fto gene has the positive relationship with metabolic issues. therefore, it’s necessary pay attention to the above and dangerous sicknesses, espec...

the gene coding claudin (cldn5) is located on 22q11. since the proteins of cldn5 family are a ma-jor component for barrier-forming tight junctions, it may be important to test whether or not the cldn5 locus could be associated with schizophrenia.a total of 150 individuals affected with schizophrenia and 150 healthy persons were recruited. the relation-ship between the three single nucleotide po...
