Dietary exposure and health risk characterization of aflatoxin B1, ochratoxin A, fumonisin B1, and zearalenone in food from different provinces in Northern Vietnam

Food Control, 2020
A dietary exposure and health risk assessment of mycotoxins including aflatoxin B1, fumonisin B1, ochratoxin A, and zearalenone was conducted in 3 provinces in Northern Vietnam namely Hanoi, Thanh Hoa, and Ha Giang.

Ochratoxins: A global perspective

Mycopathologia, 2006
Ochratoxins have been overshadowed by better-known mycotoxins, but they are gaining importance. Here we consider ochratoxins in the context of aflatoxins, which are better understood than ochratoxins on many levels. We review recent work on taxonomic distribution, contamination of commodities, biosynthesis, toxicity and regulatory aspects of ...

Advances in biosensors for the detection of ochratoxin A: Bio-receptors, nanomaterials, and their applications.

Biosensors & bioelectronics, 2019
Ochratoxin A (OTA) is a class of mycotoxin mainly produced by the genera Aspergillus and Penicillium. OTA can cause various forms of kidney, liver and brain diseases in both humans and animals although trace amount of OTA is normally present in food ...

Urinary ochratoxin A and ochratoxin alpha in pregnant women

Food and Chemical Toxicology, 2012
This study determined exposure of pregnant women to ochratoxin A (OTA). Forty samples of first-void urine samples from Croatian women in the third trimester of pregnancy were analyzed for OTA and its major metabolite ochratoxin alpha (OTα). The subjects filled a short food frequency questionnaire (FFQ).

Immunotoxic activity of ochratoxin A

Journal of Veterinary Pharmacology and Therapeutics, 2006
Ochratoxin A (OTA) is an immunosuppressant fungal compound, produced by toxigenic species ofAspergillusandPenicilliumfungi in a wide variety of climates and geographical regions. The contamination of food by this mycotoxin takes place primarily during preharvest periods. Almost all types of food can be contaminated.

Ochratoxin A Exerts Neurotoxicity in Human Astrocytes through Mitochondria-Dependent Apoptosis and Intracellular Calcium Overload.

Toxicology Letters, 2019
Astrocytes are the major glial cell type in the central nervous system (CNS), and the distal part of the astrocyte forms the blood-brain barrier with nearby blood vessels.

OCHRATOXIN A IN TURKISH WINES

Journal of Food Biochemistry, 2005
In this research, 47 wine samples produced from 2001 to 2002 harvest period in four Turkish regions were analyzed for the presence of ochratoxin A (OTA). Based on the results, the OTA levels of red wines are generally higher than those of white and rose wines.

Metabolic Pathways of Ochratoxin A

Current Drug Metabolism, 2011
Ochratoxin A (OTA) as a carcinogenic of group 2B to humans is produced by various fungi strains as Aspergillus and Penicillium. It is one of the most common contaminant in foodstuff. OTA is nephrotoxic, hepatotoxic, teratogenic, and immunotoxic and is assumed to cause Balkan Endemic Nephropathy (BEN), a chronic kidney disease in humans when it is ...
