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...

Ochratoxin A (OTA), mainly produced by Aspergillus and Penicillum species, is one of the most important mycotoxin contaminants in agricultural products. It is detrimental to human health because of its nephrotoxicity, hepatotoxicity, carcinogenicity, teratogenicity, and immunosuppression. OTA structurally consists of adihydrocoumarin moiety linked with l-phenylalanine via an amide bond. OTA bio...

Ochratoxin A (OTA) is a mycotoxin produced by several fungi. Many foods can be contaminated by OTA, which is consequently found in the blood of humans and animals. It is known that OTA accumulates in the brain. The aim of this study was to investigate the effects of OTA on the brain. For this purpose, the effect of OTA on N-methyl-D-aspartate (NMDA) receptor subunits 2A (NR2A) and 2B (NR2B) in ...

Dysplastic nevus is an acquired or hereditary nevus that clinically seems atypical and pathohistologically dysplastic. The term of dysplastic nevus has changed through history and even until now the dermatologists and pathologists have not found the same conclusion for name and definition of dysplastic nevus. Epidemiology of dysplastic nevus is different depending on geographic lattitude, being...

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.

Reed nevus (pigmented spindle cell nevus) is a nevus with the histopathological features of abundant melanin, monomorphic spindle-epithelioid melanocytes, spindle cell nests confined within the epidermis and papillary dermis, and occasional upward interepidermal progression of melanocytes. Here, we reported an unusual case of Reed nevus in an 11-month-old Japanese male infant. Infantile Reed ne...

Melanocytic nevus is the benign proliferation of melanocytes. The most common location of melanocytic nevus is the skin of the extremities; however, there are few case reports of melanocytic nevus at the rectal mucosa. No prior case of malignant melanoma from melanocytic nevus at the rectal mucosa has been reported; therefore, it is unclear whether resection should be performed or close observa...
