1. Superoxide dismutase, catalase, glutathione peroxidase and gluthatione S-transferases M1 and T1 gene polymorphisms in three Brazilian population groups
Antioxidants such as superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX1) reduce the oxidation rates in the organism. Gluthatione S-transferases (GSTs) play a vital role in phase 2 of biotransformation of many substances. Variation in the expression of these enzymes suggests individual differences for the degree of antioxidant protect

2. High levels of catalase in SOD mutants of Saccharomyces cerevisae in high aeration conditions
Saccharomyces cerevisiae mutants deficient in superoxide dismutase genes (sod1Δ, sod2Δ and sod1Δsod2Δ mutants) in a stationary phase of growth under high aeration conditions were subjected to H2O2 stress. All the mutants were sensitive after H2O2 treatment. Glutathione peroxidase levels were significantly lower in sod1Δ and sod2Δ single mutants than in

3. Influence of calcium supplementation on blood lead levels and markers of lead exposure in posmenopausal women / Influência da suplementação de cálcio sobre os níveis de chumbo e indicadores da exposição ao chumbo em mulheres na pós-menopausa
The accelerated bone loss that occurs during menopause and becomes more prone in the postmenopausal period is mediated by the ending of estrogen production. This bone loss can be a threat for women in this period of life concerning to the lead toxicity. Around 95% of the lead accumulated in the body is stored in the bones and may be mobilized to the bloodstr

4. VITAMINA C PLASMÁTICA ESTÁ NEGATIVAMENTE ASSOCIADA COM A ATIVIDADE DAS AMINOTRANSFERASES EM PACIENTES COM HEPATITE C NÃO TRATADOS / PLASMATIC VITAMIN C IN NON-TREATED HEPATITIS C PATIENTS IS NEGATIVELY ASSOCIATED WITH AMINOTRANSFERASE ACTIVIES
In this study, the possible relationship between aminotransferase activities and markers of oxidative stress in hepatitis C patients was evaluated. Patients with HCV (hepatitis C virus) infection confirmed by positive HCV RNA in serum, without treatment to hepatitis C were divided into three groups: group I (15 to 39 U/L); group II (41 to 76 U/L); group III

5. Disseleneto de difenila: Um organocalcogênio com baixa toxicidade em não roedores e importantes propriedades anti-aterogênicas em modelos in vivo e in vitro / Diphenyl Diselenide: an organoselenium compound with low toxicity in non rodents and importants antiatheorgenic properties
Atherosclerosis is a chronic inflammatory condition associated with an overproduction of oxidant species. Since low density lipoprotein (LDL) oxidation plays a key role in the pathogenesis of atherosclerosis, antioxidants that can inhibit this oxidative process might be useful in preventing atherosclerosis-related pathological conditions, such as cardiovascu

6. Antiulcenogenic activity of native plants of the São Paulo State savannah pertaining to the genre Indigofera / Atividade antiulcerogenica de plantas nativas do cerrado do estado de São Paulo - pertencentes ao genero Indigofera
The genus Indigofera, which includes 700 herbaceous and bush species, is one of the six largest Leguminosae genres. In São Paulo State, Brazil, nine species of this genre were already described. Indigofera truxillensis Kunt and Indigofera suffruticosa Mill, commonly known as ?índigo?, are found predominately at São Paulo State?s savannah. There are just a

7. Superoxide release and cellular gluthatione peroxidase activity in leukocytes from children with persistent asthma
Asthma is an inflammatory condition characterized by the involvement of several mediators, including reactive oxygen species. The aim of the present study was to investigate the superoxide release and cellular glutathione peroxidase (cGPx) activity in peripheral blood granulocytes and monocytes from children and adolescents with atopic asthma. Forty-four pat
