A vast amount of circumstantial evidence implicates oxygen-derived free radicals (especially superoxide and hydroxyl radical) and high-energy oxidants (such as peroxynitrite) as mediators of inflammation, shock, and ischemia/reperfusion injury. The aim of this review is to describe recent developments in the field of oxidative stress research. The first(More)
The polymorphic cytochrome P450 isoenzymes (CYPs) 2C9, 2C19 and 2D6 metabolise many important drugs, as well as other xenobiotics. Their polymorphism gives rise to important interindividual and interethnic variability in the metabolism and disposition of several therapeutic agents and may cause differences in the clinical response to these drugs. In this(More)
Gentamicin is an antibiotic effective against Gram-negative infection, whose clinical use is limited by its nephrotoxicity. Oxygen free radicals are considered to be important mediators of gentamicin-mediated nephrotoxicity, but the exact nature of the radical in question is not known with certainty. We have investigated the potential role of superoxide in(More)
NMDA receptors and Ca2+/calmodulin-dependent kinase II (CaMKII) have been reported to be highly concentrated in the postsynaptic density (PSD). Although the possibility that CaMKII in PSD might be associated with specific proteins has been put forward, the protein or proteins determining the targeting of the kinase in PSD have not yet been identified. Here(More)
A double methylazoxymethanol (MAM) intraperitoneal injection was prenatally administered to pregnant rats at gestational day 15 to induce developmental brain dysgeneses. Thirty adult rats from 8 different progenies were investigated with a combined electrophysiological and neuroanatomical analysis. The offspring of treated dams was characterized by(More)
The distribution of the oxidation polymorphism related to cytochrome CYP2D6 (debrisoquine type) was determined in 246 healthy Italian volunteers. Phenotyping was based on HPLC determination of the dextrometorphan/dextrorphan concentration ratio (metabolic ratio) in urine samples collected over an 8 h interval following a single oral 30 mg dose of(More)
Thiazolidinedione rosiglitazone and 15-deoxy-Delta12,14-prostaglandin J2 (15d-PGJ2), are two peroxisome proliferator-activated receptor (PPAR)-gamma ligands. The aim of this study was to investigate the effect of rosiglitazone and 15d-PGJ2 on the lung injury caused by bleomycin administration. Mice subjected to intratracheal administration of bleomycin(More)
BACKGROUND Nonadherence to antihypertensive treatment is a common problem in cardiovascular prevention and may influence prognosis. We explored predictors of adherence to antihypertensive treatment and the association of adherence with acute cardiovascular events. METHODS AND RESULTS Using data obtained from 400 Italian primary care physicians providing(More)
1. Nitric oxide (NO), peroxynitrite, formed from NO and superoxide anion, poly (ADP-ribole) synthetase have been implicated as mediators of neuronal damage following focal ischaemia. Here we have investigated the effects of n-acetylcysteine (NAC) treatment in Mongolian gerbils subjected to cerebral ischaemia. 2. Treatment of gerbils with NAC (20 mg kg(-1)(More)
OBJECTIVE Splanchnic artery occlusion shock (SAO) causes an enhanced formation of reactive oxygen species (ROS), which contribute to the pathophysiology of shock. Here we have investigated the effects of n-acetylcysteine (NAC), a free radical scavenger, in rats subjected to SAO shock. METHODS AND RESULTS Treatment of rats with NAC (applied at 20 mg/kg, 5(More)
