1. Simulação elétrica do efeito de dose total em células de memória estática (SRAM)
Nesta dissertação é apresentado o estudo da célula SRAM estática de 6 transistores, com tecnologia CMOS, sendo utilizada em ambiente exposto à radiação. Foi verificado, através de simulação com o Hspice (HSPICE, 2009; KIME, 1998) e com a análise de Monte Carlo, o seu comportamento com relação à dose de ionização total (Total Ionization Dose,

2. Grape juice and norbixin : in vitro in vivo antioxidant activity / Atividade antioxidante in vitro e in vivo de suco de uva e da norbixina
Epidemiological studies shown that the consumption of diets rich in plant foods and beverages is associated with reduction in the development of chronic-degenerative diseases. These foods are sources of substances such as carotenoids and polyphenols that can act as chemoprotectives agents, reducing the damage caused by reactive oxygen species, formed both in

3. UtilizaÃÃo do dosÃmetro Fricke para dosimetria de mÃquinas teleterapÃuticas, irradiadores gammacel e aparelhos de raios-X superficiais
The chemical dosimetry has been used as a reference in the measurement of the absorbed dose, with the Fricke dosimeter, at standardization laboratories. This dosimeter is considered an absolute dosimetric standard for measurements of radiation doses ranging from 20 to 400 Gy, covering a wide energy spectrum, from X-ray, g-ray to fast electron beam. The objec

4. Estudo de bioequivalencia entre duas formulações farmaceuticas (comprimidos) contendo 20mg de Lisinopril, em voluntarios sadios de ambos os sexos
The aim of this study was to evaluate the bioequivalence between two formulations of lisinopril 20 mg. The test formulation was Lisinopril tablet 20 mg, manufactured by Medley S/A Indústria Farmacêutica (Iot # LlC 06/01-1; expiry date: june/03) and the reference formulation was Zestril@ tablet 20 mg, manufactured by Astra Zeneca (Iot # A03534; expiry date:

5. Comparative Levels of O6-Methylguanine, Pyridyloxobutyl-, and Pyridylhydroxybutyl-DNA Adducts in Lung and Liver of Rats Treated Chronically with the Tobacco-Specific Carcinogen 4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanone
The tobacco-specific nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) is a lung carcinogen in rats and may be a cause of lung cancer in smokers. NNK is metabolized by cytochromes P450 to intermediates that react with DNA forming methyl, pyridyloxobutyl (POB), and pyridylhydroxybutyl (PHB) adducts, which are critical in carcinogenesis. Th

6. Identification of New 2-Amino-3-methylimidazo[4,5-f]quinoline Urinary Metabolites from β-Naphthoflavone-Treated Mice
Metabolism of the heterocyclic amine carcinogen 2-amino-3-methylimidazo[4,5-f]quinoline (IQ) was evaluated in mice with and without 40 mg/kg β-naphthoflavone (BNF). Following an oral dose of 40 mg/kg 14C-IQ, a 24-h urine sample was collected. Metabolism was assessed by high-performance liquid chromatography, and metabolites were identified by electrosp
