Deleterious Effects of Mycotoxin Combinations Involving Ochratoxin A
Ochratoxin A (OTA) is a nephrotoxic mycotoxin with carcinogenic properties. Its presence was detected in various foodstuffs all over the world but with significantly higher frequency and concentrations in areas with endemic nephropathy (EN). Even though food is often contaminated with more than one mycotoxin, earlier studies focused on the occurrence and toxicology of only OTA. Only a limited n...
متن کاملthe effect of consciousness raising (c-r) on the reduction of translational errors: a case study
در دوره های آموزش ترجمه استادان بیشتر سعی دارند دانشجویان را با انواع متون آشنا سازند، درحالی که کمتر به خطاهای مکرر آنان در متن ترجمه شده می پردازند. اهمیت تحقیق حاضر مبنی بر ارتکاب مکرر خطاهای ترجمانی حتی بعد از گذراندن دوره های تخصصی ترجمه از سوی دانشجویان است. هدف از آن تاکید بر خطاهای رایج میان دانشجویان مترجمی و کاهش این خطاها با افزایش آگاهی و هوشیاری دانشجویان از بروز آنها است.از آنجا ک...
15 صفحه اولOCCURRENCE OF A MYCOTOXIN, OCHRATOXIN A, IN WHEAT AND ISOLATION OF OCHRATOXIN A AND CITRININ PRODUCING STRAINS OF PENICILLIUM VIRIDICATUM Ochratoxin A is a metabolite of Aspergillus ochraceus
Ochratoxin A is a metabolite of Aspergillus ochraceus Wilh. (5) and of Penicillium viridicatum Westling (8). It is highly toxic to rats and ducklings and produces liver and kidney damage (6). Both A. ochraceus and P. viridicatum have been isolated from stored grain, and ochratoxin A itself was recently found in corn (7). The presence of this toxin in rolled wheat used as livestock feed is repor...

15 صفحه اولAdult hippocampal neural stem/progenitor cells in vitro are vulnerable to the mycotoxin ochratoxin-A.
The common mycotoxin ochratoxin-A (OTA) accumulates in brain, causes oxidative stress, and elicits a DNA repair response that varies across brain regions and neuronal populations. Neural stem/progenitor cells (NSCs) prepared from hippocampus of adult mouse brain were tested for their vulnerability to the toxin in vitro. The following measurements were made in NSC cell cultures in both prolifera...
