Impact des modalités d'un exercice physique sur la neuroplasticité. Focus sur les sources de BDNF
2019
Physical exercise (EX) is recognized as the most potent non-pharmacological strategy to positively enhance brain health. From Human and animal studies there is a consensus to involve brain-derived neurotrophic factor (BDNF), a neurotrophin strongly expressed in response to EX and implicated in neuroplasticity mechanisms. Mainly expressed by neurons, BDNF is also expressed by endothelial and muscle cells. Largely sought during a physical effort, endothelium and skeletal muscle could be involved in positive effects induced by EX. Although there is a real consensus about BDNF and cerebral effect of EX, the typology of the better regimen of EX to enhance cerebral plasticity is not known. In thi…
Temporary occlusions of coronaries arteries by thermoreversible gel : leGoo.To experimental to human case
2011
ObjectifsThe objective of this work is to assess the feasibility of using the LeGoo gel to occlude the coronary arteries temporarily, to facilitate the performance of coronary bypass (off-pump technique), initially in pigs then in human. A Secondary objective was to evaluate the impact of the injection on the endothelium and myocardium.MethodesThe first study evaluated in pigs the feasibility of using LeGoo, while performing coronary bypass on the left anterior descending or on the right coronary artery and to evaluate the endothelial function of coronary arteries occluded by the gel.The second study analyzed endothelial function of internal thoracic arteries, in the area occluded by the ge…
