BC and Me – 1980 to 2003• 1980: First Meeting –NMR meeting• 1984: Joined Brit’s lab• 1984-87: Animal Models– Open Chest Animals: dog and cat

• Volume & pressure overload; ischemia; hypoxia

– Closed Chest animals: dog• Volume & pressure overload; cardiomyopathy; heart

failure; ischemia

– Other intact organs: Skeletal Muscle; liver, brain• Increase work load; ischemia

• 1987-2003: Isolated organs, cells & mitochondria

Multiple Technologies

• NMR: 31P, 23Na; 1H; 13C; 19F• NADH Fluorescence• NIR Spectroscopy• Other physiological measurements– Piezoelectric crystals: Mechanical function– Laser Doppler: flow in blood vessels; tissue perfusion– Tissue electrodes: Cae2+, Ke+, Nae+– ECG, EEG– BP, HR, LVP
