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 ...
Identification of Nef-HIV-1 domains involved in p22-phox interaction and superoxide production.
(Universidad del Zulia, 2016)
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, ...
The value of the prooxidant-antioxidant system in ensuring the immunity of plants
(Universidad del Zulia, 2020)
Mitochondrial peroxynitrite generation is mainly driven by superoxide steady-state concentration rather than by nitric oxide steady-state concentration
(MedCrave Group, 2018-03)
In biological systems, ONOO- production depends on production rates of NO and O2-, and on the reactions of these two free radicals with other biological components, which limit the local concentrations of NO and O2-. In ...
Tyrosine 9 is the key amino acid in microcin J25 superoxide overproduction
(Wiley Blackwell Publishing, Inc, 2009-11)
Escherichia coli microcin J25 (MccJ25) is a lasso-peptide antibiotic comprising 21 l-amino acid residues (G1-G-A-G-H5-V-P-E-Y- F10-V-G-I-G-T15-P-I-S-F-Y20-G). MccJ25 has two independent substrates: RNA-polymerase (RNAP) ...
Angiotensin-(1-7) blocks the angiotensin II-stimulated superoxide production
(Academic Press Ltd - Elsevier Science Ltd, 2007)
oiwa, a Female Gametophytic Mutant Impaired in a Mitochondrial Manganese-Superoxide Dismutase, Reveals Crucial Roles for Reactive Oxygen Species during Embryo Sac Development and Fertilization in Arabidopsis
(American Society Of Plant Biologist, 2013-05)
Reactive oxygen species (ROS) can function as signaling molecules, regulating key aspects of plant development, or as toxic compounds leading to oxidative damage. In this article, we show that the regulation of ROS production ...
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 ...
