Ochratoxin A (OTA) is one of the most important mycotoxins that contaminate a broad range of agricultural and food products. In this study, the occurrence of OTA in available brands of grape juice in Iran purchased from retail outlets or producer were determined for the first time using high-performance liquid chromatography (HPLC) with immunoaffinity columns(IAC) as the clean-up step. The aver...

background and objectives: non-sanitary conditions during the drying, transport and storage stages in the production of spices could introduce mycotoxin contamination. the aim of the current study was to determine the concentration of ochratoxin a (ota) in 92 commercial spices (including red pepper, black pepper, turmeric and cinnamon) imported to iran. materials and methods: ota levels were de...

Ochratoxin A (OTA) is a mycotoxin produced in corn, rice, and flour. It is a major concern for animal and human health. The purpose of this study was the evaluation of OTA contamination in bread samples gathered from bakeries, in different temperatures and durations of heating. In this study, 32 samples (4 samples of flour and 28 samples of bread) were randomly collected from different bakeries...

Ochratoxin A (OTA) is a mycotoxin naturally occurring in different foods. OTA is arguably a risk factor for Balkan endemic nephropathy (BEN). The aims of this study are to (1) test the OTA-BEN association in BEN-groups and controls and (2) determine whether urine β2-microglobulin, a marker of impaired ability of the kidneys to re-absorb, is related to OTA. BEN patients had significantly higher ...

This paper presents design concept of Operational Transconductance Amplifier (OTA). The 0.18μm CMOS process is used for Design and Simulation of this OTA. This OTA having a bias voltage 1.8 with supply voltage 1.8 V. The design and Simulation of this OTA is done using CADENCE Spectere environment with UMC 0.18μm technology file. The Simulation results of this OTA shows that the open loop gain o...

This paper presents design concept of Operational Transconductance Amplifier (OTA). The 0.18μm CMOS process is used for design and simulation of this OTA. This OTA having a biasing current of 15.6 μA with supply voltage ±1.25 V. The design and simulation of this OTA is done using CADENCE Spectre environment with UMC 0.18 μm technology file. The simulation results of this OTA shows that the open...

Lactic acid bacteria (LAB) are a promising solution to reduce exposure to dietary mycotoxins because of the unique mycotoxin decontaminating characteristic of some LAB. Ochratoxin A (OTA) is one of the most prominent mycotoxins found in agricultural commodities. The present work reports on the ability of Pediococcus parvulus strains that were isolated from Douro wines that spontaneously underwe...
