Does topiramate increase the rewarding properties of cocaine in young-adult mice limiting its clinical usefulness?
These findings suggest that topiramate increases the rewarding properties of cocaine, at least in part, by regulating dopaminergic signaling in the mesolimbic circuit. Consequently, the results of this study do not support the use of topiramate for the treatment of problems related to cocaine dependence.
Gastric bypass surgery results in resolution of the leptin resistance status that characterizes obese subjects. The study also demonstrated a significant correlation between leptin and adiponectin. This correlation provides preliminary evidence for studying a potential adiponectin-leptin cross-talking that may represent one of the physiologic pathways responsible for the regulation of food intake in humans.
