Effects of exercise on muscle metabolites and sarcoplasmic reticulum function in ovariectomized rats
(Czech Academy of Science, 2002-12)
The relationships between exercise and metabolites as well as between exercise and sarcoplasmic reticulum function were studied in gastrocnemius muscle of ovariectomized-trained rats. Prolonged moderate-intensity exercise, ...
Sarcoplasmic reticulum release channels from frog skeletal muscle display two types of calcium dependence
Calcium channels derived from sarcoplasmic reticulum of frog skeletal muscle were fused with planar lipid bilayers. Fractional open times displayed two types of calcium dependence: (i) blockable channels showed a bell-shaped ...
Rapid kinetic studies of SH oxidation-induced calcium release from sarcoplasmic reticulum vesicles
(Academic Press Inc., 1997)
We studied the kinetics of calcium release induced by SH oxidation in triads isolated from frog and rabbit skeletal muscle by measuring calcium fluxes by a fast filtration method. In both species SH oxidation induced release ...
Effect of tachycardia on myocardial sarcoplasmic reticulum and Ca2+ dynamics: a mechanism for preconditioning?
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2003-12)
We have previously demonstrated that brief episodes of tachycardia prior to a prolonged occlusion of a coronary artery, followed by reperfusion, substantially reduce the infarct size. Adenosine receptors and mitochondrial ...
Functional antagonism of beta-adrenoceptor subtypes in the catecholamine-induced automatism in rat myocardium
A method to estimate mitochondrial Ca2+ uptake in intact cardiac myocytes
(Assoc Bras Divulg CientificaSao PauloBrasil, 1996)
Diastolic SR Ca efflux in atrial pacemaker cells and Ca-overloaded myocytes
(Amer Physiological SocBethesda, 1997)
Relaxation evoked by extracellular Ca(2+) in rat aorta is nerve-independent and involves sarcoplasmic reticulum and L-type Ca(2+) channell
(ELSEVIER SCIENCE INC, 2009)
The perivascular nerve network expresses a Ca(2+) receptor that is activated by high extracellular Ca(2+) concentrations and causes vasorelaxation in resistance arteries. We have verified the influence of perivascular nerve ...
