Dopamine is typically used in the treatment of septic shock or cardiogenic shock. Dobutamine is a drug that primarily stimulatesbeta-1receptors, leading to increased inotropic and chronotropic effects. to al lesser extent, dobutamine also stimulates beta-2 adrenergic receptors, leading to vasodilatation....
Interestingly, venom induced a contraction of isolated aortic rings which was blocked by felodipine but not by prazosin, suggesting the contraction is mediated by calcium channel activation. These results suggest that the negative inotropic and chronotropic effects of the venom of N. nomurai may be ...
regulation according to changes in cardiac hemodynamic parameters such as stroke volume (SV), ejection fraction (EF), and the maximum rate of rise of systolic blood pressure (dP/d), with the aim of restoring the physiological correlation between inotropic and chronotropic cardiac function [2鈥 6...

The key difference between disc bulge and herniation is their cause. In disc bulge, the outer layer of a spinal disc extends beyond its usual boundaries without the jelly-like interior protruding into thespinal cord, while in herniation, the tough outer layer of the spinal disc has completely ...

For all patients, emergent or asymptomatic, the treatment goal is long-term control of hypertension. Potent IV agents for the im-mediate control of elevated blood pressure need to be used cautiously,bearing in mind both the side effects and the hazards of overly rapid control of hypertension. ...
