Effects of Calcium Channel Blockers on Sodium-Free Contracture in Atrial Muscle of the Rabbit [PDF]

, 1993
Effects of organic and inorganic Ca-channel blockers on Na-Ca exchange system were investigated in the rabbit atrial muscle. Atrial muscle strips were perfused with Kr-free Tyrode solution in order to depress the sodium pump activity.

Structure and function of voltage-gated sodium channel Nav1.6: Involvement in the pathological process of neural injury

Neural Regeneration Research
The voltage-gated sodium channel Nav1.6, encoded by the sodium voltage-gated channel alpha subunit 8 gene, is a crucial regulator of neuronal excitability, with widespread expression throughout the central and peripheral nervous systems.

A Novel Modified Petroresin Particle (MPRP) With Enhanced Oil–Water Selectivity for Cold Production in Heavy Oil Reservoirs

Advanced Functional Materials, EarlyView.
A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...

Comparative acute effects of the calcium channel blockers tiapamil, nisoldipine, and nifedipine on blood pressure and some regulatory factors in normal and hypertensive subjects [PDF]

, 1986
To clarify the pharmacological profile of the two new calcium channel blockers tiapamil and nisoldipine in humans, their acute effects as compared with those of the reference agent nifedipine were assessed in 10 normal subjects and 10 patients with ...

Aging Reduces L-type Calcium Channel Current and the Vasodilatory Response of Small Mesenteric Arteries to Calcium Channel Blockers

Frontiers in Physiology, 2016
Calcium channel blockers are widely used to treat cardiovascular disease (CVD) including hypertension. As aging is an independent risk factor for CVD, the use of calcium channel blockers increases with increasing age.
