Calcium phosphate synthesis: the acidic route of the wet precipitation method was performed in two steps. First, a precursor solution saturated in Ca 2+ and PO 4 3- ions was prepared by mixing 1 mol/L ...

Calcium removal from the cytosol occurs by the activity of the SR pump, by exchange of calcium for sodium via the sarcolemmal sodium-calcium exchanger (Na + -Ca 2+ exchanger), by mitochondrial calcium ...

Background —We investigated whether decreased myofilament calcium contractile activation may, in part, contribute to heart failure. Methods and Results —Calcium concentration required for 50% ...

The calcium-dependent interactions between troponin C (TnC) and other thin and thick filament proteins play a key role in the regulation of cardiac muscle contraction. Five hydrophobic residues (Phe20 ...

Calcium ion is the ubiquitous messenger in cells and plays a key role in neuronal signaling and fusion of synaptic vesicles. These vesicles are typically ∼20–50 nm in diameter, and thus their ...
