Increased caloric intake in dietary obesity could be driven by central mechanisms that regulate reward-seeking behavior. The mesolimbic dopamine system, and the nucleus accumbens in particular, underlies both food and drug reward. We investigated whether rat dietary obesity is linked to changes in dopaminergic neurotransmission in that region.(More)
The aminopyridines block several types of potassium (K+) channels and exert a direct inotropic effect on skeletal muscle by prolonging the duration of the action potential. Aging influences skeletal muscle Cl- channels and their regulation, and affects both resting whole-cell K+ conductance and adenosine triphosphate (ATP)-sensitive K+ channels, although in(More)
INTRODUCTION Noninvasive hemodynamic (HD) assessments in the emergency department (ED) might assist in the diagnosis, therapeutic plan development and risk stratification of acutely ill patients. This multinational observational study was designed to initiate noninvasive HD measurements prior to any ED patient therapeutic interventions and broadly evaluate(More)
INTRODUCTION Non-invasive, continuous hemodynamic monitoring is entering the clinical arena. The primary objective of this study was to test the feasibility of such monitoring in a pilot sample of Emergency Department (ED) stroke patients. Secondary objectives included analysis of hemodynamic variability and correlation of continuous blood pressure(More)
