PhysiologyGastrin is the major hormone that stimulates the gastric phase of gastric secretion. It is released from G cells in the antral mucosa in response to food in the stomach, particularly proteins and amino acids, and to a lesser extent, to the presence of acid. Gastrin stimulates the parietal cells to secrete hydrochloric acid and intrinsic factor.

OrthodonticsOrthodontic wires are often made from stainless steel, which contains iron, carbon, and other alloying elements. The term "iron carbide" refers to a compound of iron and carbon, typically represented as Fe₃C. In the context of orthodontic wires, the microstructure can exist in different phases depending on the temperature and composition. Austenite is a face-centered cubic (FCC) structure that is stable at high temperatures and is known for its ductility and strength. When orthodontic wires are heated during the manufacturing process, they can be formed into austenite, which can then be transformed into martensite upon cooling, providing the wire with desirable properties for orthodontic applications.
