Cytochromes P450 (CYPs) are a superfamily of 57 genes coding for drug metabolizing enzymes and endobiotic metabolizing enzymes (steroids, eicosanoids, vitamins...). This is the main metabolizing enzyme system for foreign compounds, including drugs, which has a primary role in organism protection against potential harmful insults from the environment(More)
Clinical utility of phosphodiesterase 4 (PDE4) inhibitors as anti-inflammatory agents has, to date, been limited by adverse effects including nausea and emesis, making accurate assessment of emetic versus anti-inflammatory potencies critical to the development of inhibitors with improved therapeutic indices. In the present study we determined the in vitro(More)
We sought to evaluate a new protocol designed to maintain long-term, nonrecovery, surgical anesthesia in Sprague-Dawley rats. In the first phase, two groups of rats were anesthetized with two different dose combinations of Domitor (medetomidine) and Zoletil 100 (tiletamine-zolazepam) to investigate their efficacy in induction of anesthesia. One combination(More)
Multiple experimental neuroscience techniques rely on the use of general anaesthesia to minimize the discomfort associated to animal restraint and to achieve a more effective control of relevant physiological parameters. In order to minimise potential interference on brain neuronal activity, such studies are typically conducted at low anaesthetic doses.(More)
Pharmacological Magnetic Resonance Imaging (phMRI) methods have significantly expanded the stimulation repertoire available to preclinical fMRI research, by allowing to selectively probe the activity of specific brain circuitries and neurotransmitter systems. However, the application of phMRI to animal models is constrained by a number of experimental(More)
The aim of the present study was to characterize the pharmacokinetic-pharmacodynamic relationship of GV143253A, a novel trinem anti-methicillin-resistant Staphylococcus aureus (MRSA) agent active against gram-positive cocci, including multidrug-resistant clinical isolates. An in vitro pharmacodynamic study with methicillin-susceptible S. aureus (MSSA) and(More)
GV104326 is the first member of a new class of antibiotics (tribactams) selected for development. It combines a particularly broad spectrum (including gram-negative and gram-positive aerobes and anaerobes) with high potency, resistance to beta-lactamases, and complete stability to dehydropeptidases. Comparative MICs were determined for GV104326 against 415(More)
