We recorded MCGs at 1600 locations on a 16×16 mm2 grid on the surface of an isolated rabbit heart stimulated with a point electrode in the center of the grid.
What I've learned is that it's the short little "love affairs" that keep my heart stimulated and my loving energy constantly engaged.
These data demonstrate that acute modulation of HBP and protein O-GlcNAcylation in the heart stimulates fatty acid oxidation, possibly by increasing plasma membrane levels of FAT/CD36, raising the intriguing possibility that the HBP and O-GlcNAc turnover represent a novel, glucose dependent mechanism for regulating cardiac metabolism.
These data suggest that these apelin peptides enhanced ATP formation in reperfused hearts, stimulating glucose utilization.
Perhaps starting at home with their parents, they've learned how to turn older people on, or at least touch their hearts, stimulate their protective instincts, and make them feel guilty.
Elevated left ventricular end-diastolic pressure in isolated rat hearts stimulated relaxin gene expression, providing a possible mechanism for the finding of enhanced relaxin expression in ventricles from heart failure patients.
A study in the chioralose urethane anesthetized beagle dog assessed the potency of darifenacin, tolterodine, oxybutynin, and propiverine on pelvic nerve-stimulated bladder contractions, trigeminal nerve stimulated salivation, and heart rate (Gupta et al 2006).
The contracting heart was stimulated with platinum-stimulating electrodes applied to the epicardial surface, usually 15 min at 10 Hz, and was allowed to reach its physiological steady state.
By crafting drugs known as beta-blockers, which interact mainly with just one of these (a version of the beta adrenergic receptor), pharmacologists have devised a way of mimicking some of adrenalin's functions (those concerned with regulating the heart) without stimulating others, such as the fight-or-flight reaction in the brain.
Fluid retention increases stress on the heart, further stimulating the hormonal activation and myocardial remodeling.
