calcium chloride (CaCl 2), a granular white chemical with an unpleasant taste. It is used in a concentrated solution of the chloride salt of calcium to replenish calcium in the blood and also has uses in cardiac resuscitation.
Neuropeptides are small protein-like molecules (peptides) used by neurons to communicate with each other. They are neuronal signaling molecules that influence the activity of the brain in specific ways.
From Wikipedia, the free encyclopedia. Brain natriuretic peptide or B-type natriuretic peptide (BNP) (also ventricular natriuretic peptide) is a 32-amino acid polypeptide secreted by the ventricles of the heart in response to excessive stretching of heart muscle cells (cardiomyocytes). Either BNP or NT-proBNP can also be used for screening and prognosis of heart failure. 2  Both are also typically increased in patients with left ventricular dysfunction, with or without symptoms (BNP accurately reflects current ventricular status, as its half-life is 20 minutes, as opposed to 1â2 hours for NT-proBNP).
