L-type Ca²⁺ currents determine the shape of cardiac action potentials (AP) and the magnitude of the myoplasmic Ca²⁺ signal, which regulates the contraction force. The auxiliary Ca²⁺ channel subunits ...
In the 21st century, human tissue can be generated from stem cells and severed limbs are successfully reattached, while the physiological processes governing life’s most fundamental event—childbirth ...
A healthy heart beats at a regular pace determined by electrical pulses generated inside the heart which spread as waves through the cardiac muscle. Such excitation waves produce normal heart ...
