Nitric Oxide and Superoxide Anion Production During Heparin-Induced Capacitation in Cryopreserved Bovine Spermatozoa
(Wiley Blackwell Publishing, Inc, 2011-02)
The aim of this work was to quantify NO, O2− and ONOO− production during heparin-induced capacitation of cryopreserved bovine spermatozoa. A time dependent hyperbolic increase was observed for heparin-dependent capacitation, ...
(−)-Epicatechin prevents alterations in the metabolism of superoxide anion and nitric oxide in the hearts of L-NAME-treated rats
(Royal Society of Chemistry, 2014-10)
The aim of this work was to evaluate the effects of (−)-epicatechin administration in the heart of a rat model with reduced NO production that follows a short-term treatment with L-NAME. Sprague-Dawley rats were treated ...
Cadmium modulates NADPH oxidase activity and expression in sunflower leaves
(Springer, 2012-06)
The production of reactive oxygen species (ROS) and the ways by which ROS are generated are very important facts related to heavy metal toxicity in plants. In this work, superoxide anion (O2·-) generation diminished in ...
Larrea divaricata Cav (Jarilla): Production of superoxide anion, hydrogen peroxide and expression of zymosan receptors
(Taylor & Francis, 2008-09)
Larrea divaricata is a plant widely used in folk medicine in Argentina. This work aimed to study the mechanisms of decoction activity on the release of oxygen reactive species. Decoction increased the binding of zymosan-FITC ...
Angiotensin-(1-7) blocks the angiotensin II-stimulated superoxide production
(Academic Press Ltd - Elsevier Science Ltd, 2007)
Modifications in nitric oxide and superoxide anion metabolism induced by fructose overload in rat heart are prevented by (−)-epicatechin
(Royal Society of Chemistry, 2016-04)
Fructose overload promotes functional and metabolic derangements in humans and in animal experimental models. Evidence suggests that dietary flavonoids have the ability to prevent/attenuate the development of metabolic ...
Blood pressure-lowering effect of dietary (-)-epicatechin administration in L-NAME-treated rats is associated with restored nitric oxide levels
(Elsevier Science Inc, 2012-11)
Epidemiological and intervention studies have shown that the intake of certain chocolates or cocoa products decreases blood pressure (BP) in humans. (-)-Epicatechin is the most abundant flavanol present in cocoa seeds and ...
Photodegradation of hydroxylated N-heteroaromatic derivatives in natural-like aquatic environments: A review of kinetic data of pesticide model compounds
(Pergamon-Elsevier Science Ltd, 2005-12)
In the present review, the results published by our group and others related with the study of the kinetic behavior and, in some cases, the mechanism of the dye-promoted photooxygenation of several hydroxypyridines, ...
A kinetic approach to assess oxidative metabolism related features in the bivalve Mya arenaria
(Springer, 2012-12)
Electron paramagnetic resonance uses the resonant microwave radiation absorption of paramagnetic substances to detect highly reactive and, therefore, shortlived oxygen and nitrogen centered radicals. Previously, steady ...
Ni-thiosaccharinate complexes: Synthesis, characterization and DFT studies. Biological properties as superoxide dismutase mimetics and as anti-carcinogenic agents
(Elsevier Science SA, 2019-08-01)
This report describes the synthesis and characterization of two nickel thiosaccharinate complexes, [Ni(tsac)2(PPh3)2] (1) and [Ni(tsac)2(dppe)]·CH3CN (2), where tsac = thiosaccharinate anion, PPh3 = triphenylphosphane and ...
