Tissue-, substrate-, and site-specific characteristics of mitochondrial reactive oxygen species generation
(ELSEVIER SCIENCE INC, 2009)
Reactive oxygen species are a by-product of mitochondrial oxidative phosphorylation, derived from a small quantity of superoxide radicals generated during electron transport. We conducted a comprehensive and quantitative ...
Diphenylacetaldehyde-generated excited states promote damage to isolated rat liver mitochondrial DNA, phospholipids, and proteins
(Pergamon-elsevier Science LtdOxfordInglaterra, 1999)
ESR spin trapping studies of free radicals generated from nitrofuran derivative analogues of nifurtimox by electrochemical and Trypanosoma cruzi reduction
(TAYLOR & FRANCIS LTD, 2003-08)
Electron spin resonance (ESR) spectra of radicals obtained from two analogues of the antiprotozoal drug nifurtimox by electrolytic and Trypanosoma cruzi reduction were analyzed. The electrochemistry of these compounds was ...
Ferritin-dependent radical generation in rat liver homogenates
(Elsevier Ireland, 2009-10)
The hypothesis of this study was that mammalian ferritin (FER) has the ability of releasing Fe in the tissue to catalyze the generation of free radicals, such as ascorbyl (A) and hydroxyl radical (OH), that might lead to ...
EPR in the Characterization of the Shade Effect on Translucence, Remaining Free Radicals, and Polymerization Depth of Commercially Available Resin Composites
(SPRINGER WIEN, 2010)
The aim of this study was to assess the relation between the number of free radicals generated and the polymerization depth in two different commercial brands of resin composites with different colors and translucence. ...
OXIDATIVE DAMAGE OF MITOCHONDRIA INDUCED BY FE(II)CITRATE OR T-BUTYL HYDROPEROXIDE IN THE PRESENCE OF CA2+ - EFFECT OF COENZYME-Q REDOX STATE
(Pergamon-elsevier Science LtdOxfordInglaterra, 1995)
Efeito da complexação de metais aos antiinflamatórios na ação contra agentes oxidativos e radicais livres: ação do cetoprofeno
(Editora Unesp, 2011-01-01)
Os radicais livres são espécies altamente reativas geradas nos organismos vivos com a finalidade de proteção. Porém, em algumas circunstâncias, estes são responsáveis pela ocorrência ou o agravo de danos teciduais. Muitos ...
Electrochemical, UV-visible and EPR studies on nitrofurantoin: Nitro radical anion generation and its interaction with glutathione
(HARWOOD ACAD PUBL GMBH, 2000)
This paper deals with the reactivity of the nitro radical anion electrochemically generated from nitrofurantoin with glutathione. Cyclic voltammetry (CV) and controlled potential electrolysis were used to generate the nitro ...
Estudo fotoquímico da ação anti-radicalar de compostos polifenólicos empregando espectrofotometria e HPLC-UV
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2010-02-22)
The interest in antioxidants has increased considerably in recent years as molecules that reduce lipid peroxidation may minimize or inhibit the oxidative damage caused to DNA, proteins and carbohydrates. Flavonoids, a group ...
