background: rfamide-related peptide-3 (rfrp-3) inhibits gonadotropin releasing hormone (gnrh) and luteinizing hormone (lh) secretion in rats. this study evaluates the effects of litter size and suckling intensity on rfrp mrna expression in the dorsomedial hypothalamic nucleus (dmh) of rats. materials and methods: a total of 32 pregnant and 4 non-lactating ovariectomized (control group) sprague-...

Nitrate is one of the major sources of nitrogen for the growth of plants. It is taken up by plant roots and transported to the leaves where it is reduced to nitrite in the. The main objective of this research was to investigate stimulatory effects of sodium nitrate, potassium nitrate, ammonia and urea on the production/generation of the nitrate reductase mRNA in Triticum aestivum plants. The pl...

introduction: it has been reported the alkaline response of pancreas to duodenal acidification is partly mediated through duodenal release of h2s, but till now the effect of duodenal acidification on gastric h2s release has not been investigated. therefore, the present study designed to evaluate the effects of duodenal acidification on gastric h2s release and level of mrna expression of cystath...

Context:MicroRNAs (miRNAs) are a class of short, endogenously-initiated, non-coding RNAs that post-transcriptionally control gene expression via translational repression or mRNA turnover. MiRNAs have attracted much attention in recent years as they play critical roles in gene expression and are promising tools with many biotech and therapeutic applications. The molecular mechanisms und...

introduction: apoptosis is an important mechanism in both physiological and pathological conditions. the bcl2 family of proteins plays a critical role in regulation of apoptotic cell death. up and down regulation of bcl2-like 12 (bcl2l12), a new member of the bcl2 family, has been reported in several malignancies. however, the expression level of bcl2l12 rarely has been studied in leukemia. thi...

background helicobacter pylori infection is associated with gastritis and marked infiltration of the gastric mucosa by several cytokines secreting inflammatory cells that contribute to sustained local inflammation. in this study, we sought to examine il-6 expression in h. pylori-infected and uninfected gastric mucosa and elucidate the implication in the pathogenesis of h. pylori-associated gast...
