Transmembrane signaling through G protein-coupled receptors (GPCRs) controls a diverse array of cellular processes including metabolism, growth, motility, adhesion, neuronal signaling and blood coagulation. The numerous GPCRs and their key roles in both normal physiology and disease have made them the target for more than 50% of all prescribed drugs. GPCR(More)
BACKGROUND Thrombin is the most potent agonist of platelets and plays a critical role in the development of arterial thrombosis. Human platelets express dual thrombin receptors, protease-activated receptor (PAR) 1 and PAR4; however, there are no therapeutic strategies that effectively target both receptors. METHODS AND RESULTS Platelet aggregation studies(More)
INTRODUCTION Despite extensive data supporting the use of platelet glycoprotein (GP) IIb/IIIa (GPIIb/IIIa) inhibitors in the therapy of patients with acute coronary syndromes (ACS), there is considerable debate as to the optimal choice of antiplatelet regimen. The objective of this study was to conduct a detailed time-resolved analysis of the effects of the(More)
OBJECTIVES The objective of this case series is to review our experience with spontaneous pneumomediastinum, review the available literature, and refine the current clinical approach to this uncommon condition. METHODS The case notes of all patients admitted to the George Washington University Medical Center with spontaneous pneumomediastinum from April(More)
Reperfusion after severe crush injury is an infrequent, but life-threatening condition. It is a unique aspect of prehospital medicine that occurs in the presence of emergency responders attempting to extricate and treat patients who have suffered a crushing injury. These events are unlikely to occur in the hospital setting and, as a result, remain poorly(More)
