Research progress of ochratoxin a bio-detoxification.

Toxicon, 2022
Ochratoxins (OTs) is an extremely toxic mycotoxin in which Ochratoxin A (OTA) is the most toxic and prevalent in the ochratoxin family. OTA is among the five most critical mycotoxins that are subject to legal regulations.

A colorimetric biosensor for simultaneous ochratoxin A and aflatoxins B1 detection in agricultural products.

Food Chemistry, 2020
Colorimetric biosensors have been widely applied to mycotoxins testing. However, the colorimetric assay previously reported used a single color to detect one mycotoxin, and there were few reports on the simultaneous detection of multiple mycotoxins.

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).

Sensitive aptamer-based fluorescene assay for ochratoxin A based on RNase H signal amplification.

Food Chemistry, 2019
A new assay for the selective and sensitive aptamer-based fluorescent biosensor for ochratoxin A (OTA) detection is proposed. It consists of a ribonuclease H (RNase H)-assisted cycle response that leads to a significant amplification of the signal, which

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.
