background: the association between methylene tetrahydrofolate reductase polymorphism and coronary artery diseases risk has been both confirmed and refuted in a number of published studies. the aim of this study was to investigate whether genetic polymorphisms of mthfr (c677t, a1298c) contributed to the development of myocardial infarction (mi). materials and methods: the present case-control s...

Second order conservative languages with a Maltsev polymorphism also have a majority polymorphism. Abstract The paper proves that for any second order conservative constraint language with a Maltsev polymorphism there is a majority polymor-phism. Moreover, the majority polymorphism can be defined by the Maltsev polymorphism.

the e-selectin mediates the interaction of activated endothelial cells with leukocytes and plays a fundamental role in the pathogenesis of asthma. it has been suggested that an s/r (serine128arginine) polymorphism of e-selectin alters ligand binding function. our purpose in this study was to determine whether this serine128arginine polymorphism influences the risk of asthma and also to analyze ...

objective: the methylenetetrahydrofolate reductase (mthfr) gene polymorphism c677t is suspected to be a risk factor for psychiatric disorders, but it remains inconclusive whether the mthfr polymorphism c677t is imputed to vulnerability to schizophrenia and bipolar disorder. method: we prompted impetus to appraise this polymorphism in an iranian population. therefore, 90 patients with bipolar di...

background inflammatory bowel disease (ibd) is a chronic, relapsing, inflammatory disorder of the gastrointestinal tract that includes two entities, crohn`s disease (cd) and ulcerative colitis (uc). as with other complex diseases, both genetic susceptibility and environmental factors play role in the pathogenesis of these diseases. the tumor necrosis factor α (tnf-α) gene is located in the ibd3...

We investigated the association between metamphetamine dependence and TaqI A polymorphism of the dopamine receptor D2 gene (DRD2), I/D polymorphism in angiotensin-converting enzyme (ACE) and M235T polymorphism of the angiotensinogen gene (AGT) in 93 unrelated metamphetamine-dependent subjects and 131 controls. Our results did not prove any association of TaqI A polymorphism of the DRD2 gene, I/...
