background: genetic variation influences susceptibility/resistance to tuberculosis. cxcl10 is involved in t-cell migration and stimulation of natural killer cells in mycobacterium tuberculosis infection. objectives: we aimed to investigate the genetic polymorphisms in promoter of the cxcl10 gene in patients with pulmonary tuberculosis (ptb) and healthy controls, to clarify whether polymorphisms...

one of the most striking features in autosomal dominant polycystic kidney disease (adpkd) is the difference at onset age of end-stage renal disease (esrd). modifier genes may play a role in this phenotypic variability. the mutated nitric oxide synthase 3 gene (nos3), have a modifier effect on the severity of adpkd by impairment of nos3 activity and decreasing of renal vascular nitric oxide prod...

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...
