background: migraine is a common neurovascular disorder with multifactorial and polygenic inheritance. the aim of this study was to investigate the association of a migraine without aura and ala379val polymorphism of lipoprotein-associated phospholipase a2 (lp-pla2) gene in the iranian population. methods: in this study, 103 migraine patients and 100 healthy controls were enrolled. dna samples ...

backgroundattention deficit hyperactivity disorder (adhd), is a multifactorial disorder and converging evidence has implicated abnormalities of dopamine neurotransmission. the aim of this study was to examine the association of -141 polymorphisms in drd2 gene with adha among iranian-azeri population.materials and methods a case–control association study included 153 patients with attention defi...

nitric oxide is an important vasorelaxant factor that it inhibits platelet adhesion and proliferation of smooth muscle cells. no is synthesized from l-arginine by means of endothelial nitric oxide synthase (enos) which is an isoform of  nitric oxide synthase.in the present study, we examined  possible association between the 27 base pair (bp) repeat  polymorphism in intron 4 of the  enos3 gene ...

conclusions in conclusion, chit1 24 bp duplication might not be a candidate gene for susceptibility to ptb. larger studies are necessary to confirm these findings in various populations. results homozygous wild type, heterozygous and homozygous mutant frequencies of chit1 24 bp duplication polymorphism were 43.9%, 43.9% and 12.2% in controls and 42.8%, 45.1% and 12.1% in ptb patients. we found ...

DNA polymorphism within diacylglycerol transferase 2 (DGAT2) / monoacyl glycerol transferases 2 (MOGAT2), leptin and butyrophilin genes were analysed using PCR-SSCP in Murrah buffalo. The single strand conformation polymorphism (SSCP) analysis of amplified gene fragment in exon 5 of MOGAT2, exon 3 of leptin and intron 1 of butyrophilin gene revealed different patterns. A, B and C showed the fol...

Background: Human cornea expresses functional Fas-ligand capable of killing Fas+ activated lymphocytes. Fas expression is partly regulated by -670 A/G polymorphism in the promoter region of Fas gene. Objective: The aim of the present study is to determine the association between Fas-670A/G polymorphism and survival of corneal transplantation. Methods: In 276 graft recipients who mainly underwen...

The DMA (DM ? chain) gene, a member of non-classical MHC class II plays an important role in the process presenting antigen peptides by producing DM protein. This study aimed to identify polymorphism gene and their associations with disease resistance traits such as total IgY concentration ND antibody titers IPB-D2 chicken line. sample used was 101 chickens consisted 81 G0 (53 female 28 male) 2...

background :cytotoxic t lymphocyte-associated antigen-4 (ctla-4) is an important negative regulator of t-cell responses. the -1722tc polymorphism of the ctla-4 gene may be associated with systemic lupus erythematosus (sle) risk, but related results from previous studies have been inconsistent. we carried out a meta-analysis to assess this association more precisely.   methods : a systematic sea...
