This study examined Ca(2+) handling mechanisms involved in cardioprotection induced by chronic intermittent hypoxia (CIH) against ischemia-reperfusion (I/R) injury. Adult male Sprague-Dawley rats(More)
We hypothesized that testosterone at physiological levels enhances cardiac contractile responses to stimulation of both alpha(1)- and beta(1)-adrenoceptors by increasing Ca(2+) release from the(More)
