... is not compromised by exposure to cold temperatures; and (2) support data from other studies, which show that, in contrast to salmonids, cod cardiac performance/myocardial contractility is not dependent upon humoral adrenergic stimulation. In situ heart preparations were obtained for the cod with only minor...

... ; Matsuba et al., 2009 ). This change in cTn function is thought to be responsible for the increased rate of muscle relaxation that occurs following β-adrenergic stimulation in the heart ( Kentish et al., 2001 ; Li et al., 2004 ; Rarick et al., 1999 ; Solaro and Rarick, 1998 ). Following...

...Todd E. Gillis; Jordan M. Klaiman SUMMARY β-Adrenergic stimulation of the mammalian heart increases heart rate, the strength of contraction as well as the kinetics of force generation and relaxation. These effects are due to the phosphorylation of select membrane and thin filament proteins by cAMP...

...-acceleration control mechanisms in place just after the heartbeat stage, while cardio-inhibitory control was not functional until after hatching. Chronic hypoxia exposure triggered bradycardia, increased the response to adrenergic stimulation in embryos and larvae, and delayed the onset of cholinergic control...

...MIKKO NIKINMAA; KIRSTI TIIHONEN; MARITA PAAJASTE We investigated the mechanisms by which adrenergic activation of sodium/proton exchange reduces the pH gradient across the membrane of rainbow trout red cells. In untreated cells, adrenergic stimulation caused a significant increase in the proton...
