Fluid and electrolyte transport with special emphasis on Na/H and Na/Ca exchange in the heart and Na/H exchange and Na+K+2Cl cotransport in the Blood Brain Barrier. Current studies are aimed at better understanding the role of Na uptake via these transporters in ischemic brain and myocardium as well under conditions of diabetic ketoacidosis. Ongoing studies use magnetic resonance imaging and spectroscopy to assess changes in brain and myocardial Na, pH, Ca, and high-energy phosphates. Diffusion and perfusion weighted imaging are also used to determine cerebral edema and blood flow.
