UNLABELLED Ochratoxin A (OTA) is a toxic secondary metabolite of fungi belonging to the Aspergillus and Penicillium genera, its presence in human blood being the primary indicator of exposure. AIM In the present study we determined OTA in 38 blood samples collected from healthy Romanian subjects of both genders. MATERIAL AND METHODS The OTA was determined through the direct, competitive, so...

In this paper, a general two-admittance current-mode circuit structure using Dual-Output OTA (DO-OTA) is explored to derive new third-order unsymmetrical band-pass filters. The proposed circuits are attractive as they require less number of OTAs and use only grounded capacitors. The other advantageous features offered by proposed filters are ease of design, good sensitivity and orthogonal tunab...

In vineyards the presence of certain fungi may lead to the production of the mycotoxin ochratoxin A (OTA) and subsequent contamination of grapes and wine. Furthermore, winery wastewaters contaminated with OTA may represent an environmental hazard. Therefore, it is imperative to assess the fate of this mycotoxin in conventional wastewater treatment systems. The aim of the present work was to ass...

Background and purpose: Contamination of food materials such as rice to mycotoxins (aflatoxin B1 and Ochratoxin A) is a major health concern. This causes more concerns especially in countries that rice is the main food. Nephrotoxic, immunotoxic, mutagenic, teratogenic, and carcinogenic effects of such mycotoxins to human are reported by WHO and EPA. The main objective of current study was to de...

ABSTRACT       Background and Objective: Ochratoxin is a fungal toxin produced by Penicillium verrucosum and some Aspergillus species. Ochratoxin is usually found in grains, cereal products and also animal feed of livestock. The aim of this study was to measure the level of Ochratoxin in pasteurized milk samples of Golestan Province, Iran.    &nbs...

Association of ochratoxin A with cultured rat hepatocytes occurs at 4 degrees C, and the saturation level in the medium is 0.3 mM ochratoxin A, with maximal binding after 60 min. At 37 degrees C the level of cell-associated ochratoxin A increased up to 6 h and remained at 2 nmol of toxin per mg of cell protein for 30 h. With increasing concentrations of ochratoxin A, increasing amounts of the t...
