The aim of our work was to study (1) the antioxidant properties of lipoic acid (LA) and its reduced metabolite dihydrolipoic acid (DHLA) formed by reduction of LA and (2) the effects of treatment with LA and DHLA on (a) K+ efflux from human red blood cells and (b) post-ischemic recovery and oxidative stress in isolated perfused rat hearts challenged with an(More)
Cardiopulmonary Bypass (CPB) is thought to generate reactive oxygen species associated with a systemic inflammation and neurotrophins seem to be involved in cardiovascular inflammatory reactions. The aim of this study was to determine the impact of CPB on plasma neurotrophins levels and to appreciate the links existing between inflammation, oxidative stress(More)
Brain-derived neurotrophic factor (BDNF) and TrK receptors play an important role in vascular development and response to injury. In this study, we investigated the participation of the BDNF/TrK pathway and oxidative stress during the development of hypertension in spontaneously hypertensive rats (SHR). In SHR and normotensive rats (WKY) at 6 and 13 weeks(More)
We wondered if Zucker obese (ZO) rats would be a good experimental model to evaluate cardiovascular complications of metabolic syndrome (MS). ZO rats were compared with both their littermate controls, Zucker lean (ZL) rats and to Wistar rats (reference strain). We designed this work:(i) to measure certain physical and biochemical characteristics of MS; (ii)(More)
Little is known about the role of neurotrophins (NT) under adult vascular homeostasis in normal and pathological conditions. The NT family, including nerve growth factor and brain-derived neurotrophic factor (BDNF) are expressed in atherosclerotic vessels. Previous studies demonstrated that plasma BDNF levels were increased in the coronary circulation in(More)
The ability to authenticate the feed given to animals from the animal products has become a major challenge for scientists, monitoring bodies and commercial entities alike. This study compared two methods based on the use of the visible reflectance spectrum of the fat to discriminate pasture-fed (P) from stall concentrate-fed (S) lamb carcasses. A total of(More)
UNLABELLED Circulation on blood extracorporeally through plastic tubing activates several pathways including systemic inflammation and oxidative stress. These phenomena are suspected to participate to neurological and cardiovascular side effects observed in the patients under cardiopulmonary bypass (CPB). A direct relationship, in diabetic patients, between(More)
Neurotrophic-factors research is dominated by neurotrophins (NT): a family of polypeptides which includes molecules such as Nerve Growth Factor (NGF) and the Brain-Derived Neurotrophic Factor (BDNF). They are homodimeric polypeptides. NTs interact with classes of receptors on responsive cells: protein-tyrosine kinase-type receptors (Trk family). It is well(More)
