Reversed-phase high performance liquid chromatographic (RPHPLC) determination of amino-acids with on-line pre-column ortho-phthalaldehyde (OPA) derivatization and fluorescence detection is rapid and sensitive. However, high-performance ionexchange chromatography (HP-IEC) with post-column ninhydrine reaction is the most widely used amino-acid (AA) assay for biological samples. These two methods ...
Background: Gastric cancer (GC) is one of the most common cancers worldwide and in Iran. Conventional therapies are surgery and chemotherapy. Current studies are evaluating natural compounds in inhibiting growth of cancer cell. In this study isolated peptide melittin with 26 amino acids from bee venom and its impact on the viability and proliferation of gastric cancer cells was investigated. Me...
migration of compounds from packaging materials is one of the most important aspects of food safety. epoxy resins have been in inner coatings of food cans since the 1960s. these resins can be produced from bisphenol-a diglycidyl ether (badge) that is also utilized as a starter. migration of potentially toxic compounds in epoxy resins used for commercial cans is a very important food safety issu...
Five wild plant species belonging to different families (Chenopodium album, Plantago major, Elytrigia elongata, Filipendula ulmaria and Nigella sativa) widely spread in Russian Federation and the former USSR were evaluated for their ability to inhibit growth of two important human food-borne pathogens (Escherichia coli O157:H7 and Listeria monocytogenes strain EGD-e) and eight plant pathogens (...
