in study, spherical silver nanoparticles (snps) were synthesized by chemical reduction method from a metal precursor silver nitrate in presence of an anionic surfactant and strong reducing agent. in this experimental work, snps are synthesized in presence of different concentration of stabilizing agent and effect of stabilizing agent on size distribution of snps have been observed. further anti...

According to circumstance of kerman sarcheshmeh cooper complex that its anode slime is mainly consisted of Cu, Ag, Au, Pb and Se. In this work, recovery of silver from anode slime and subsequent synthesis of silver nanoparticles from leaching solution was made. Silver was separated from anode slime by using of HNO3 and HCl. X-Ray fluorescence spectroscopy (XRF) was used to characterize anode sl...

objective(s): accumulating evidence has demonstrated that mirnas contribute to various genetic and epigenetic modifications in the pathogenesis of gastric cancer (gc). recent studies focused on the four single nucleotide polymorphisms (snps) of pre-mirnas including rs11614913, rs3746444, rs2910164, and rs2292832. it was suggested that these four snps were significantly associated with the risk ...

background: single nucleotide polymorphism (snps) are considered as one of the underlying causes of male infertility. proper sperm chromatin packaging which involves replacement of histones with protamines has profound effect on male fertility. over 20 snps have been reported for the protamine 1 and 2. materials and methods: the aim of this study was to evaluate the frequency of two previously ...

abstract snp typing is now a well-established genotyping system in bacillus anthracis studies. in the original standard method of van erth, snps at 13 loci of the b. anthracis genome were analyzed. in order to simplify and make appropriate this expensive method to low-budget laboratory settings, 13 primer pairs targeting the 13 corresponding snps were designed. besides, a universal pcr protocol...

It has been suggested that single nucleotide polymorphisms (SNPs) in genes involved in Toll-like receptors (TLRs) pathway may exhibit broad effects on function of this network and might contribute to a range of human diseases. However, the extent to which these variations affect TLR signaling is not well understood. In this study, we adopted a bioinformatics approach to predict the consequences...
