objective(s): streptococcus pyogenes produces extracellular hyaluronidase enzyme. this enzyme is directly associated with the spread of the organism during infection. the objective of the present study was to clone and express the nucleotide sequence of the enzyme which is involved in hyaluronidase enzymatic activity. materials and methods: the enzymatic region of hyaluronidase gene was detecte...
antimicrobial peptide brevinin-2r induces the secretion of a pro-inflammatory cytokine in hepg2 cells
introduction: antimicrobial peptides as the body's defense strategy play an important role in resistance against infection of microorganism. these peptides are able to modulate the immune and inflammatory processes through the production of defensive molecules. therefore, the modulatory effects of brevinin-2r, an antimicrobial peptide extracted from the skin of the frog (rana ridibunda), w...
Buchnera strains from most aphid subfamilies studied to date have been found to carry the leucine gene cluster (leuA, -B, -C, and -D) on a plasmid, an organization unique among bacteria. Here, however, we demonstrate a classical chromosomal location of the cluster in Buchnera sp. strain PSY from the aphid Pemphigus spyrothecae (subfamily Pemphiginae). The genes that flank leuABCD in Buchnera sp...
ژن tlr4 بر روی کروموزوم 17 قرار گرفته و دارای 3 اگزون و 2 اینترون است. این ژن باعث سنتز پروتئینی با تعداد843 اسید آمینه می شود که تنظیم و شروع کننده یپاسخ های ایمنی به هنگام آلودگی با باکتری های گرم منفی است. هدف از این مطالعه تجزیه و تحلیل ساختاری ژن tlr4 و ارتباط آن با صفات ایمنی در دو سویه بومی و تجاری بود. برخی از صفات ایمنی مثل میزان عیار پادتن های تولید شده علیه srbc (عیار پادتن کل، ta؛ ع...
background: ovarian tissue cryopreservation is an alternative strategy to preserve the fertility of women predicted to undergo premature ovarian failure. this study was designed to evaluate the expression of folliculogenesis-related genes, including factor in the germline alpha (figla), growth differentiation factor-9 (gdf-9), follicle-stimulating hormone receptor (fshr), and kit ligand after v...
Psychovisual rate-distortion optimization (Psy-RD) has been used in the industrial video coding practice as a tool to improve perceptual video quality. It has earned significant popularity through the wide spread of the open source x264 video encoders, where the Psy-RD option is employed by default. Nevertheless, little work has been dedicated to validate the impact of Psy-RD optimization on pe...
objective: the incidence of breast cancer is approximately one million which makes this cancer one of the most common among women worldwide. breast cancer comprises 7% of the total death rate caused by cancers. several strategies that use tumor-associated antigen (taa) vaccination and early detection of breast cancer are clinically being developed. breast cancer is caused by increased over expr...
background: niche cells, regulating spermatogonial stem cells (sscs) fate are believed to have a reciprocal communication with sscs. the present study was conducted to evaluate the effect of ssc elimination on the gene expression of glial cell line-derived neurotrophic factor (gdnf), fibroblast growth factor 2 (fgf2) and kit ligand (kitlg), which are the main growth factors regulating sscs deve...
background: peroxisome proliferator activated receptor gamma (pparγ), a member of nuclear receptor superfamily, comprises two isoforms in mouse. these two isoforms are encoded by different mrnas, which are arisen by alternative promoter usage. there are two promoter regions upstream of pparγ gene. a 3 kb fragment, containing several transcription factor binding sites, acts as pparγ1 promoter re...
calorie restriction through ingesting no or minimal amounts of food and caloric beverages for periods of time is called fasting. fasting can affect body through changing in physical and metabolic adaptations, as well as mineral and hormonal status. however, psychological effects and sometimes medical complications are likely in case of inappropriate fasting. fasting is associated with changes i...
