Background and purpose: Helicobacter pylorus is a well-recognized cause of chronic active gastritis, peptic ulcer disease (PUD) and linked to the development of gastric adenocarcinoma. Heat shock protein (HSP) acts as molecular chaperons in the folding of newly synthesized proteins in cells and assist in the refolding of damaged proteins.The HSP70-2 gene has a pst1 site due to an A to G transit...

Introduction & Objective: Enterococci have emerged as the leading nosocomial pathogens. In addition to natural resistance to many agents, enterococci have also developed plasmid- and transposon-mediated resistance to high concentrations of aminoglycosides. High-level gentamicin resistance (HLGR) of enterococci results in the failure of drug synergism with an aminoglycoside plus cell-wall-acti...

Background and Aim: Genetic changes and mutations in the genes involved in spermatogenesis can occur by environmental and congenital factors. Considering, the extensive use of diazinon in the farms and because we found no study on the effects of diazinon on the expression of CatSper1 gene, a key element of male fertility, we decided to perform this study in order to determine the effects of dif...

The aim of this study was to find the footprint of selection in native Sarabi and Taleshi cattle breeds 296 cattle from two breeds were sampled and genotyped. by 40 k microarray of illumine company. 43 animals were removed because their ACR was below 0.09. Markers were filtered with minor allele frequency (MAF) equal 0.01 and Hardy-Weinberg equilibrium test (10-6). After filtering, 28782 marker...
