Inhibition of in vivo leishmanicidal mechanisms by tempol: Nitric oxide down-regulation and oxidant scavenging
(ELSEVIER SCIENCE INC, 2008)
Tempol (4-hydroxy-2,2,6,6-tetramethyl-1-piperidinyloxy) has long been known to protect experimental animals from the injury associated with oxidative and inflammatory conditions. In the latter case, a parallel decrease in ...
Nitric oxide regulates neurogenesis in adult olfactory epithelium in vitro
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009-02-05)
Nitric oxide regulates neurogenesis in the developing and adult brain. The olfactory epithelium is a site of neurogenesis in the adult and previous studies suggest a role for nitric oxide in this tissue during development. We ...
Lichen metabolites modulate hydrogen peroxide and nitric oxide in mouse macrophages
The activities of perlatolic acid (1), atranorin (2), and lecanoric acid (3) and their derivatives, such as orsellinates and β-methyl orsellinates obtained by alcoholysis, were assessed for stimulation of the release of ...
Regulation of human luteal steroidogenesis in vitro by nitric oxide
To evaluate the effect of nitric oxide (NO·) in human corpus luteum (CL) function, we investigated the expression and the presence of NO· synthase (NOS) in the human CL and the action of NO· on the in vitro luteal ...
Influence of hyperthyroidism on the activity of liver nitric oxide synthase in the rat
(Academic Press Inc., 1997)
Hyperthyroidism enhances the prooxidant activity of the liver by elevating superoxide radical and/or hydrogen peroxide generation in microsomal, mitochondrial, and peroxisomal fractions, with an increased respiratory burst ...
Role of peroxynitrite in macrophage microbicidal mechanisms in vivo revealed by protein nitration and hydroxylation
(Pergamon-elsevier Science LtdOxfordInglaterra, 2001)
Nitric oxide activates a potassium current in olfactory receptor neurons from Caudiverbera caudiverbera and Xenopus laevis
The putative role of nitric oxide (NO) in the physiology of olfactory receptor neurons (ORNs) is controversial. Here we report that pulses of NO caused an outward current in voltage-clamped isolated olfactory neurons. The ...
Interaction of 5-aminosalicylic acid with nitrous acid: Formation of the diazonium derivative and nitric oxide release
The reaction of 5-aminosalicylic acid (5-ASA) with nitrous acid has been studied at low pH under conditions that simulate a gastric environment. The course of the reaction was followed by UV-visible and fluorescence ...
