objective(s): this study was performed to investigate the effects of mucosal acidification on mrna expression and protein synthesis of cystathionine gamma lyase (cse), cystathionine beta synthase (cbs), and mucosal release of h2s in gastric mucosa in rats. materials and methods:thirty-two rats were randomly assigned into 4 groups (8 in each), including: the control group, hcl (10 mm) treated gr...

Vegetables may be preserved by fermentation, direct acidification, or a combination of these, along with pasteurization, to yield products with an extended shelf life and enhanced safety.  Effect of lowering the pH, either by adding acid or lactic fermentation, on thermal process requirements for canned vegetables was investigated. Malic acid was preferred for acidification of canned vegetables...

background : helicobacter pylori is a major human gastric for various gastro duodenal diseases.a number of putative virulence factors such as dupa, homb, tnpa have been described. to date,none were found to be significantly associated with specific h. pylori-related diseases (e.g. gastric cancer and duodenal ulcer). methods : the primary aim of this study was to test the h. pylori hrga genotype...

water crisis is one of the basic problems in the arid and drought prone areas like iran. this condition in the recent years has aggravated due to drought phenomenon. thus, using poor water quality has increased in areas where good quality is not available. in this study, in order to investigate clogging, 5 types of emitters including micro flapper, netafim, corona, axios and iran drip were test...

objective(s): prostaglandins have been shown to mediate the gastro-protective effect of sodium hydrosulfide (nahs) but effect of nahs on mrna expression of prostaglandin e2 receptors (ep1, 3-4; eps) has not been investigated. therefore, this study designed to evaluate the effect of nahs on mrna expression of eps receptors in response to mucosal acidification and distention-induced gastric acid ...
