Abstract Transcription factors (TFs) play an essential role in molecular biology by regulating gene expression. The binding sites of TFs can vary a large amount and the numerous possible locations make their detection challenging issue. Recently, several machine learning approaches using nucleotide sequence data were applied to classify DNA sequences regarding Factor Binding Sites (TFBS). We pr...

host innate immunity can affect the clinical outcomes of helicobacter pylori infection, including gastritis, gastric ulcer, gastric adenocarcinoma, and malt lymphoma. nucleotide binding oligomerization domain (nod)-1 and -2 are two molecules of innate immunity which are involved in the host defense against h. pylori . this study aimed to evaluate the effect of the expression level of nod1 and n...

urokinase might play a role in the formation of kidney stones. this study was done to determine the association between +4065 t/c polymorphism at the 3′-untranslated region of urokinase gene and calcium kidney stones. this case-control study was carried out on 70 cases with a history of calcium kidney stones and 70 controls from the baqiyatallah hospital of tehran in 2013. the study of polymorp...

conclusions lepr q223r polymorphisms may confer a significant risk of nafld and coronary atherosclerosis. the a allele in the k109r polymorphism might be considered an independent risk factor for coronary atherosclerosis in nafld patients. objectives to investigate the association of lepr polymorphisms at q223r and k109r with the risks of nafld and coronary atherosclerosis in the chinese han po...

a 50-day feeding trial was conducted to evaluate the effects of yeast nucleotide in diets on growth performance, serum immune indices and muscle composition of ancherythroculter nigrocauda(mean initial body weight, 23.30±0.59 g). seven isonitrogenous (approximately 42.76% crude protein) and isoenergetic (17.43 kj g−1 gross energy) experimental diets with varying levels of yeast nucleotide (0[co...

Metallothionein (MT) is important because it binds tightly to heavy metals to decrease their toxicity. DNA was isolated from 30 toxic metal exposed and 30 toxic metal unexposed Zebu cows. The amplified metallothionein isoform-2 (MT-2) PCR product (489 bp) was further used for PCR-RFLP and DNA sequencing. MT-2 TaqI PCR-RFLP revealed homozygous genotype (AA) except for the E23 animal (AB). The ge...

objective mitochondrial dna (mtdna) is considered a candidate modifier factor for neuro-degenerative disorders. the most common type of ataxia is friedreich's ataxia (fa). the aim of this study was to investigate different parts of mtdna in 20 iranian fa patients and 80 age-matched controls by polymerase chain reaction (pcr) and automated dna sequencing methods to find any probable point mutati...
