Nitric Oxide: Oxygen Radical Interactions in Atherosclerosis
(Sociedad de Biología de Chile, 2000)
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 ...
Effect of nωnla, an inhibitor of No-synthase, on the release of tissue-plasminogem activator from rat aorta
Alterations in the synthesis or enhanced inactivation of nitric oxide (NO) and increase in fibrin deposition in the vascular bed lead to an imbalance that can induced intravascular coagulation. NO is produced through ...
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 ...
Myenteric denervation in gastric carcinogenesis: Differential modulation of nitric oxide and annexin-A1
This study evaluated the properties of endogenous nitric oxide synthases (NOS) and annexin-A1 (ANXA1) and determined how they can be exploited in the N-methyl-N-nitro-N-nitrosoguanidine (MNNG)-induced gastric carcinogenesis ...
Effect of NωNLA or dexamethasone on vascular hyporeactivity induced by E. coli endotoxin in sham and adrenalectomized rats
Induction of iNOS by bacterial products is considered to be part of the defense mechanism against infection. However, it has been suggested that the bacterial-induced NO-overproduction may be involved in the vascular ...
Nitric oxide and carotid body chemoreception
(Sociedad de Biología de Chile, 2001)
Expression of inducible nitric oxide synthase is increased in acute myeloid leukaemia
