The subject of myocardial energetics was extensively reviewed by Gibbs (62) for
Physiological Reviews in 1978 and by Gibbs and Chapman (68) for Handbook of …

Efficiency is defined as the ratio of the energy delivered by a system to the energy supplied
to it. Depending on the particular question being addressed, there exist a plethora of …

Hemodynamic and angiographic parameters, muscle fiber diameter, nonmuscle tissue
content, and myosin light chain isoform composition were determined in the left ventricle of …

The distribution of cardiac myosin isoenzymes, using gel pyrophosphate electrophoresis,
was studied in laboratory rats during acclimation to heat (34° C, 0–2 month) with and without …

Essential hypertension is characterized by skeletal muscle insulin resistance but it is
unknown whether insulin resistance also affects heart glucose uptake. We quantitated whole …

Cardiac mechanics and metabolic performance were studied in isolated perfused hearts of
heat-acclimated (AC) rats (at 34 degrees C for 1 mo) and their age-matched controls (C) …

We investigated the expression of myosin subunits (myosin heavy chains) as well as light
chains and the in vivo phosphorylation of the phosphorylatable myosin light chain in the …

Diabetes mellitus causes congestive heart failure in humans, independent of
atherosclerosis. The present study extends previous work on the reversibility, with insulin, of …

To evaluate the role of dietary sodium and antihypertensive drugs in the modulation of
myocardial structure, especially myosin isozymic pattern, renal hypertensive rats (two …

In order to investigate the cardiac effects of antihypertensive therapies in one-clip two-kidney
hypertension in rats, we compared the consequences on myosin isoenzyme profile and on …
