Control of size and shape is a challenge in nanoparticle synthesis. Synthetic and biosynthetic (both extracellular and intracellular) methods are used to prepare silver nanoparticle (SNP). In this study, the behavior of three strains of Staphylococcus aureus (S. aureus) was investigated in the presence of silver nitrate intra- and extracellularly. S. aureus strains biosynthesized SNPs intracell...

The bovine leptin (LEP) gene was widely used as a candidate gene for molecular selection to improve productivity traits of cattle. This study was carried out to identify single nucleotide polymorphisms (SNPs) in the LEP gene of Sumba Ongole (SO, Bos indicus) cows using sequencing method. A total of 31 animals were used in this study for analyses. Research showed that total of 16 SNPs w...

background: it has been demonstrated that insulin signaling pathway related genes have important roles in polycystic ovary syndrome (pcos) risk. the goal of present investigation was to assess the potential association between insr/nsii (rs2059806) and insr/pmli (rs1799817) snps and pcos. methods: 50 women with pcos and 47 normal controls entered the study. nsii and pmli snps in the insr gene w...

interleukin-1β (il-1β), the prototypical pro-inflammatory cytokine, is produced by macrophages following exposure to bacterial products. its role is to act upon several cell types at the site of infection to stimulate the production of pro-inflammatory molecules that will cause increase in vascular permeability. therefore, il-1β regulates the initiation and development of acute inflammation tha...

background esophageal, stomach, and colorectal cancers are commonly lethal gastrointestinal tract (git) neoplasms, causing almost two million deaths worldwide each year. some environmental risk factors are acknowledged; however, genetic defects can significantly contribute to predisposition to git cancers. accordingly, recent works have shown that single-nucleotide polymorphisms (snps) within m...

background: the main goal of this study was to conduct a comparative population genetic study of turkish speaking iranian azeris as being the biggest ethno-linguistic community, based on the polymorph markers on y chromosome.  methods: one hundred turkish-speaking azeri males from north-west iran (tabriz, 2008-2009) were selected based on living 3 generations paternally in the same region and n...

diacylglycerol acyltransferase1 (dgat1) has been introduced as a strong potential candidate gene for milk fat content in cattle. dgat1 gene plays a key role in the final step of triglyceride synthesis. in this study, the genetic variability in the region spanning exon 1 to exon 2 of the buffalo dgat1 gene was investigated by dna sequencing. two hundred buffaloes belonging to three indigenous po...

Straw nursery pots (SNPs), which utilize agricultural residues such as wheatstraw and corn stalks as raw materials, can be widely used in the transplantingof seedlings of crops, vegetables, flowers and trees. Plastic nursery pots (PNPs)and direct sowing (DS) were used as controls in evaluating the effects of SNPson plant growth, dry matter partitioning, yields and economic benefits oftransplant...

Background: Urinary tract infections are one of the most frequent health problems and Uropathogenic Escherichia coli is the major pathogen resulting UTIs. The severity of UTIs is caused by the expression of a large range of virulence factors.In this study, we evaluated the allelic frequency fimH gene, in UPECs isolated from patients with UTIs. This study also aimed to determine the roles of C64...
