چکیده

En France, on compte environ 5,5 millions de Français souffrant d’épisodes dépressifs majeurs, soit 8 % de la population française. L’objectif pharmacologique pour l’ensemble des antidépresseurs proposés à ce jour aux cliniciens était d’augmenter la concentration cérébrale en monoamines. Pour ce faire, trois mécanismes principaux sont recherchés : un mécanisme d’inhibition enzymatique de la dégradation des monoamines pour les Inhibiteurs de la Monoamine Oxydase de type A (IMAOA ; non sélectif initialement, puis partiellement sélectifs ; irréversibles initialement, puis réversibles) ; un mécanisme de blocage du transporteur chargé de la recapture des monoamines pour les inhibiteurs de la recapture (imipramine), puis inhibiteurs plus spécifi ques de la recapture de la sérotonine ou de la recapture de la noradrénaline ; et enfi n des molécules inhibant à la fois la recapture de la sérotonine et celle de la noradrénaline) ; et un mécanisme de blocage direct des récepteurs des monoamines pour certaines molécules surtout noradrénergiques.

The Different Mechanisms of Action Potential Propagation in the Heart

It was thought previously that cardiac muscle gap junctions provide low-resistance connections between cells and permit the local-circuit current to flow. Some evidences show that myocardial cells may not require low-resistance connections for successful propagation of the action potential (AP). It seems that some other types of mechanisms must be involved in AP propagation. In this article, we...
