The Inhibitory Effects of Ca2+ Channel Blocker Nifedipine on Rat Kv2.1 Potassium Channels. [PDF]
It is well documented that nifedipine, a commonly used dihydropyridine Ca2+ channel blocker, has also significant interactions with voltage-gated K+ (Kv) channels.

Alpha1 -adrenergic stimulation selectively enhances endothelium-mediated vasodilation in rat cremaster arteries. [PDF]
We have systematically investigated how vascular smooth muscle α1 -adrenoceptor activation impacts endothelium-mediated vasodilation in isolated, myogenically active, rat cremaster muscle 1A arteries.

A 59-year-old man ingested 900 mg of nifedipine. Profound hypotension, sinus and atrioventricular node dysfunction, and hyperglycemia resulted. The patient's condition responded favorably to aggressive treatment with intravenous fluids, calcium, and dopamine.

Ontogeny of purinergic receptor-regulated Ca2+ signaling in mouse cortical collecting duct epithelium [PDF]
Changes in ATP-induced increase in {[}Ca2+], during collecting duct ontogeny were studied in primary monolayer cultures of mouse ureteric bud (UB) and cortical collecting duct (CCD) cells by Fura-PE3 fluorescence ratio imaging.

Elucidation of molecular kinetic schemes from macroscopic traces using system identification [PDF]
Overall cellular responses to biologically-relevant stimuli are mediated by networks of simpler lower-level processes. Although information about some of these processes can now be obtained by visualizing and recording events at the molecular level, this

Ca2+ transients are not required as signals for long-term neurite outgrowth from cultured sympathetic neurons [PDF]
A method for clamping cytosolic free Ca2+ ([Ca2+]i) in cultures of rat sympathetic neurons at or below resting levels for several days was devised to determine whether Ca2+ signals are required for neurite outgrowth from neurons that depend on Nerve ...

Phase 1 repolarization rate defines Ca2+ dynamics and contractility on intact mouse hearts. [PDF]
In the heart, Ca2+ influx through L-type Ca2+ channels triggers Ca2+ release from the sarcoplasmic reticulum. In most mammals, this influx occurs during the ventricular action potential (AP) plateau phase 2.

Metabolism of the dihydropyridine calcium channel blockers mebudipine and dibudipine by isolated rat hepatocytes [PDF]
The prototype 1,4-dihydropyridine (1,4-DHP) nifedipine, indicated for the management of hypertension and angina pectoris, has drawbacks of rapid onset of vasodilating action and a short half-life.
