Journal ArticleDOI
Lipid peroxidation in hippocampus early and late after status epilepticus induced by pilocarpine or kainic acid in Wistar rats.
Felipe Dal-Pizzol,Fábio Klamt,Monica Ryff Moreira Roca Vianna,Nadia Schröder,João Quevedo,Mara da Silveira Benfato,José Cláudio Fonseca Moreira,Roger Walz +7 more
TL;DR: Results indicating a putative role of reactive oxygen species in kainic acid and pilocarpine induced epilepsy are indicated.
Journal ArticleDOI
Espécies reativas de oxigênio e de nitrogênio, antioxidantes e marcadores de dano oxidativo em sangue humano: principais métodos analíticos para sua determinação
Sandra Mary Lima Vasconcelos,Marília O. F. Goulart,José Benedito de França Moura,Vanusa Manfredini,Mara da Silveira Benfato,Lauro T. Kubota +5 more
TL;DR: In this article, the chemistry of reactive oxygen and nitrogen species, their biological sources and targets, particularly, biomolecules implicated in the redox balance of the human blood, and appraise the analytical methods available for their detection and quantification.
Journal ArticleDOI
Retinol supplementation induces oxidative stress and modulates antioxidant enzyme activities in rat sertoli cells.
Felipe Dal-Pizzol,Fábio Klamt,Mara da Silveira Benfato,Elena Aida Bernard,José Cláudio Fonseca Moreira +4 more
TL;DR: It is reported here that retinol caused cellular oxidative stress and modulated superoxide dismutase, catalase and glutathione peroxidase activities in cultured Sertoli cells.
Journal ArticleDOI
Blood Antioxidant Parameters in Sickle Cell Anemia Patients in Steady State
Luísa Lauermann Lazzaretti,Isabel Heinzmann Griebeler,Vanus.a. Manfredini,Vanessa Duarte Martins Brandão,Mara da Silveira Benfato,Ana Paula Santin,Sandrin.e. Wagner,Simone Martins de Castro,Maria do Carmo Ruaro Peralba +8 more
TL;DR: The data support the growing evidence that patients with SCA are subjected to chronic oxidative stress and are able to oxidative damage in biological macromolecules such as proteins and lipids.
Journal ArticleDOI
Retinol supplementation induces DNA damage and modulates iron turnover in rat Sertoli cells.
Felipe Dal-Pizzol,Fábio Klamt,Mario Luis Conte da Frota,Lais Fernandes de Moraes,José Cláudio Fonseca Moreira,Mara da Silveira Benfato +5 more
TL;DR: It is reported here that retinol caused cellular DNA damage probably involving cellular iron accumulation, and these characteristics could be responsible for the increased incidence of lung cancer associated with retinoids supplementation.
