Introduction: Gastric cancer is the fourth common cancer and the second leading cause of death from cancer worldwide. Omega fatty acids are a group of non-saturated fatty acids of long chains derive from linolenic, linoleic and oleic fatty acids. The current study aimed at examining the possible effects of oral administration of omega-3, -6 and -9 fatty acids on gastric cancer cell apoptosis in...

Background & Aim: Hydroxycinnamic acids are one of the most important bioactive substances of Echinacea drugs. These compounds possess immuno-enhancing activity and thus, total hydroxycinnamic acids are mostly used as the main criterion for quality control of Echinacea purpurea and its drugs.  Hence, the quality control of Echinacea requires to develo...

Background Previous studies have reported inconsistent findings regarding the efficacy of omega-3 fatty acids on pregnant women with major depressive disorder (MDD). This meta-analysis was conducted to systematically evaluate the clinical applicability of omega-3 fatty acids in treating depression in pregnant women. Methods Randomized controlled trials (RCTs) that compared omega-3 fatty acids ...

The proximate composition, amino acids and fatty acids composition in the muscle of wild, inshore and offshore cage-cultured large yellow croaker, Pseudosciaena crocea (Richardson, 1846), were determined to identify nutritional differences. Wild fish groups showed highest content of moisture and crude protein, but the lowest lipid content. Offshore cage-cultured fish showed significantly higher...

Two dimensional thin layer chromatography on polyamide sheets is a useful method for identification of PTH-amino acids which have very close Rf-values. The solvent systems described here are particularly effective and have an edge over other solvent systems used for the separation of PTH-amino acids. The solvent systems provide a clear separation of all PTH-amono acids except lle / Leu in a...

objective(s) motility plays a major role in pathogenicity of helicobacter pylori, yet there is  scarce data regarding its chemotactic behaviour. the present study was designed to investigate the chemotactic responses of local isolates of h. pylori towards various sugars, amino acids, as well as some other chemical substances. materials and methods chemotaxis was assayed by a modified adler’s me...

conclusions despite rapidity, automation, accuracy, cost-effectiveness, high sensitivity, and high specificity of molecular techniques, each type of molecular technology has its own advantages and disadvantages. results various types of molecular biology tools can be used to detect and quantify viral genomic elements and analyze the sequences. these molecular assays are proper technologies for ...

addition of potassium cyanide to a mixture of schiff base and lithium perchlorate afforded a-aminonitriles in high yields. addition of potassium cyanide to a methanolic solution of schiff base and phosphoric acid afforded a-aminonitriles. when the reaction mixture was refluxed it gave a-amino acids in high yields.

campylobacter is known to be one of the most common causes of human intestinal disorders. since poultry are known to be the main reservoirs for this pathogen, decreasing this bacterium in intestinal tract could be beneficial in reducing contamination of poultry products. the effects of probiotic (primalac®), medicinal plant (sangrovit®) and organic acid (selko-ph®) as broiler feed additives on ...
