Intensifying screens in radiography use the physical property of fluorescence, where X-ray photons are converted into light photons. This light then exposes the film, which reduces the amount of radiation exposure needed to create an image.

Calcium is absorbed mainly in the duodenum and jejunum by an active transport mechanism regulated by 1,25 (OH)2 D3 (calcitriol). It is transported across the brush border of intestinal epithelial cells via TRPV6 channels and binds to calbindin. The absorbed calcium is then delivered to the basolateral membrane by calbindin, and from there it is transported into the bloodstream by either the sodium-calcium exchanger (NCX) or calcium-dependent ATPase.

Cardiac conditions requiring prophylaxis include prosthetic cardiac valves, previous infective endocarditis, congenital heart disease, and cardiac transplantation recipients with valvulopathy. Prophylaxis is needed for procedures involving manipulation of gingival tissue or periapical regions.
