1. Desenvolvimento de método eletroanalítico para determinação direta de cobre em biodiesel e monitoramento do metal em biodiesel exposto a condições simuladas de armazenamento
A simple, effective and low cost for copper determination in biodiesel, without decomposition of the sample is presented. The samples of biodiesel were diluted in a hydro-ethanolic solution (containing HCl as supporting electrolyte) generating a homogeneous ternary system (water-ethanol-biodiesel) in which copper was detected directly using potentiometric st

2. Interações de peroxirredoxinas citossólicas da levedura Saccharomyces cerevisiae com peróxidos. Estudos cinéticos e funcionais / Saccharomyces cerevisiae cytosolic peroxiredoxin interactions with peroxides. Kinetics and functional studies
Peroxiredoxins constitute a family of cysteine-based peroxidases that are able to reduce hydrogen peroxide, organic peroxides and peroxinitrite to water, alcohol and nitrite, respectively, through the use of reducing equivalents provided by thioredoxin, thioredoxin reductase and NADPH. Peroxiredoxins are abundant enzymes (correspond to approximately 0.7% of

3. NADPH oxidase–derived free radicals are key oxidants in alcohol-induced liver disease
In North America, liver disease due to alcohol consumption is an important cause of death in adults, although its pathogenesis remains obscure. Despite the fact that resident hepatic macrophages are known to contribute to early alcohol-induced liver injury via oxidative stress, the exact source of free radicals has remained a mystery. To test the hypothesis

4. Measurement of endothelial cell free radical generation: evidence for a central mechanism of free radical injury in postischemic tissues.
Oxygen free radicals have been demonstrated to be important mediators of postischemic reperfusion injury in a broad variety of tissues; however, the cellular source of free radical generation is still unknown. In this study, electron paramagnetic resonance measurements with the spin trap 5,5'-dimethyl-1-pyrroline-N-oxide (DMPO) demonstrate that bovine endoth
