mycotoxins are small, toxic chemical products produced as secondary metabolites by a few fungal spices that readily colonise crops and contaminate them with toxins in the field or after harvest. in this study a liquid chromatographic method was developed for the simultaneous determination of aflatoxins (afs) (b 1 , b 2 , g 1 , and g2), ochratoxin a (ota) and zearalenone(zea) toxins in wheat. fo...
Spitz nevus is a variant of melanocytic nevus which is histopathologically defined as large spindle and/or epithelioid cells. Angiomatoid Spitz nevus is a rare histologic variant of desmoplastic Spitz nevus characterized by prominent vasculature. We present a case of angiomatoid Spitz nevus, celluar type, that has not been reported before. We provide another example to show the remarkable diver...
Dermoscopy is a practical, non-invasive tool that can be used to distinguish tinea nigra from other lesions appear macroscopically similar, including acral nevus. Under dermoscopy, presents with pattern of spiculated gray-brown pigment deposition, whereas nevus most often as brown deposition in parallel furrow pattern.
Blue nevus is a benign melanocytic lesion, typically asymptomatic and of unknown etiology. Many histological subtypes are recognized, the most commons being: common blue nevus, cellular blue nevus, and combined blue nevus. New rare variants have been described in the literature, with emphasis on eruptive blue nevus, plaque, agminate, linear, with satellitosis, disseminated, familial and targeto...
Mould and mycotoxin contamination in food OTA toxicity Ochratoxin A producers Occurrence of Ochratoxin A Effect of water activity on OTA production OTA destruction during roasting of coffee Levels and distribution of OTA in green coffee (contamination, survey) Effect of processing and handling on OTA content of green coffee Effect of caffeine on OTA production Socioeconomic impact of coffee pro...
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 ...
Design of Operational Transconductance Amplifier for Biquad Filter Applications in 0.18μm Technology
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...
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...
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...
