Membrane Depolarization Causes a Direct Activation of G Protein-Coupled Receptors Leading to Local Ca²⁺ Release in Smooth Muscle

Membrane depolarization activates voltage-dependent Ca²⁺ channels (VDCCs) inducing Ca²⁺ release via ryanodine receptors (RyRs), which is obligatory for skeletal and cardiac muscle contraction and ...

Finding about how water gets into neurons provides new treatment targets for deadly brain swelling

High-efficiency transporters that work like a shuttle system to constantly move ions into and out of neurons appear to slam into reverse following a stroke or other injury and start delivering instead ...

PR Interval

The PR interval is the time from the beginning of the P wave (atrial depolarization) to the beginning of the QRS complex (ventricular depolarization). The normal PR interval measures 0.12-0.20 seconds ...
