1. Atividade peroxidásica da enzima superóxido dismutase 1 humana: produção do radical carbonato, dimerização covalente da enzima e implicações para a esclerose lateral amiotrófica / Peroxidase activity of human superoxide dismutase 1: production of the carbonate radical, covalent dimerization of the enzyme, and implications to amyotrophic lateral sclerosis
A esclerose lateral amiotrófica (ELA) é uma doença neurodegenerativa que afeta os neurônios motores levando a atrofia muscular e morte por insuficiência respiratória. Esta patologia se manifesta de forma esporádica ou familiar, que são indistinguíveis clinicamente. Mutações na enzima antioxidante superóxido dismutase 1 (hSod1) respondem por aprox

2. Papel do peroxinitrito na atividade leishmanicida de macrófagos em modelos murinos / Role of peroxynitrite in macrophage leishmanicidal activity in murine models
Os mecanismos oxidativos pelos quais macrófagos exercem atividade microbicida permanecem em discussão, e estudos com hospedeiros animais serão essenciais para elucidar tal questão. Nesse trabalho, estudamos os mecanismos microbicidas de macrófagos in vivo comparando parâmetros de infecção nas lesões de camundongos resistentes (C57Bl/6) e suscetívei

3. Chemiluminescence by Listeria monocytogenes.
Listeria monocytogenes cells suspended in brain heart infusion broth or in carbonated saline solution emitted light (chemiluminescence) that could be detected by a liquid scintillation spectrometer. This chemiluminescence was inhibited by superoxide dismutase and catalase but not by the hydroxyl radical scavengers mannitol and benzoate; it was also dependent

4. Direct Magnetic Resonance Evidence for Peroxymonocarbonate Involvement in the Cu,Zn-Superoxide Dismutase Peroxidase Catalytic Cycle*
Cu,Zn-superoxide dismutase (SOD1) is a copper- and zinc-dependent enzyme. The main function of SOD1 is believed to be the scavenging and detoxification of superoxide radicals. Nevertheless, the last 30 years have seen a rapid accumulation of evidence indicating that SOD1 may also act as a peroxidase, an alternative function that was implicated in the ons

5. Nitric oxide, oxidants, and protein tyrosine nitration
The occurrence of protein tyrosine nitration under disease conditions is now firmly established and represents a shift from the signal transducing physiological actions of •NO to oxidative and potentially pathogenic pathways. Tyrosine nitration is mediated by reactive nitrogen species such as peroxynitrite anion (ONOO–) and nitrogen dioxide (•NO2), for
