Myocardial free fatty acid in unanesthetized dogs at rest and during exercise.
MILLER,HARVEY I., KEUKY.YUM,AND BEATRICE C.DURHAM. Myocardial free fatty acid in unanesthetized dogs at rest and during exercise. Am. J. Physiol. 220(3) : 589-596. 197 1 .-Myocardial free fatty acid (FFA) metabolism was studied in unanesthetized dogs at various plasma FFA concentrations. Exercise and norepinephrine (NE) infusion were used to raise the FFA level while glucose infusion was used t...
متن کاملFree fatty acid metabolism of the human heart at rest.
Myocardial substrate metabolism was studied in 13 subjects at the time of diagnostic cardiac catheterization by means of palmitic acid-(14)C infusion with arterial and coronary sinus sampling. Two subjects were considered free of cardiac pathology and all, with one exception, demonstrated lactate extraction across the portion of heart under study. Data for this single lactate-producing subject ...
متن کاملHigh-altitude acclimation increases the triacylglycerol/fatty acid cycle at rest and during exercise.
High-altitude acclimation alters lipid metabolism during exercise, but it is unknown whether this involves changes in rates of lipolysis or reesterification, which form the triacylglycerol/fatty acid (TAG/FA) cycle. We combined indirect calorimetry with [2-(3)H]glycerol and [1-(14)C]palmitate infusions to simultaneously measure total lipid oxidation, lipolysis, and rate of appearance (R(a)) of ...
متن کاملRelations between plasma non-esterified fatty acid metabolism and body fat mobilization in primiparous lactating goats.
During early lactation ruminants can mobilize considerable amounts of body fat to maintain milk production. The aim of the present study was to evaluate the efficacy of tritiated water (TOH) and non-esterified fatty acid (NEFA) kinetics as means of monitoring adipose tissue fat mobilization in lactating goats. Body fat, as estimated by a two-pool model of TOH kinetics, and NEFA entry rate were ...
متن کاملNon-esterified fatty acid and glycerol kinetics and fatty acid re-esterification in goats during early lactation.
Non-esterified fatty acid (NEFA) and glycerol kinetics were studied in lactating goats to gain insight into the mechanisms by which animals in early lactation can initially mobilize and later replenish body fat reserves. Kinetic measurements were made at days 10, 38 and 76 post-partum in ten multiparous lactating does. Plasma NEFA concentrations and NEFA entry rate decreased as lactation advanc...
