... of metabolic wastes – processes that require a functional heart. The purpose of this study was to measure the metabolic response of the excised, cannulated hagfish heart to anoxia using direct calorimetry. These experiments were coupled with measurements of cardiac pH and metabolite concentrations, at multiple...

... production levels determined by direct calorimetry were in agreement with previous results: 700 and 200Jh −1 MW −1 , respectively (where MW is metabolic weight, kg 0 85 ). Metabolite determinations during normoxia and after 3 and 8 h of anoxia showed that during anoxia a thermodynamic steady state is reached...
