Choline acetyltransferase (commonly abbreviated as ChAT, but sometimes CAT) is a transferase enzyme responsible for the synthesis of the neurotransmitter acetylcholine. ChAT catalyzes the transfer of an acetyl group from the coenzyme acetyl-CoA to choline , yielding acetylcholine (ACh).
A male RP-SMA connector is the opposite in both respects – male connector body (inside threads) with a female inner sleeve contact. Reverse-polarity SMA (RP-SMA or RSMA) is a variation of the SMA connector specification that reverses the gender of the interface, as shown in Figures 1 and 2.

The comprehensive metabolic panel, or chemical screen (CMP; CPT code 80053), is a panel of 14 blood tests that serves as an initial broad medical screening tool. The CMP provides a rough check of kidney function, liver function, diabetic and parathyroid status, and electrolyte and fluid balance, but this type of screening has its limitations.
Superior mesenteric artery compressing the duodenum, featuring the superior mesenteric artery syndrome. Superior mesenteric artery (SMA) syndrome is a gastro-vascular disorder in which the third and final portion of the duodenum is compressed between the abdominal aorta (AA) and the overlying superior mesenteric artery.
SMA* (Simplified Memory-bounded Algorithm), a shortest path algorithm; SMA connector (SubMiniature version A), a coaxial RF connector; SMA 905 or F-SMA I, SMA 906 or F-SMA II, an optical fiber connector; SMA or DO-214AC, a variant of the DO-214 diode package; Surface-mount assembly, in electronics
Spinal muscular atrophy (SMA) is a rare neuromuscular disorder that results in the loss of motor neurons and progressive muscle wasting. [3] [4] [5] It is usually diagnosed in infancy or early childhood and if left untreated it is the most common genetic cause of infant death. [6]
The abbreviation refers to the homologies to the Caenorhabditis elegans SMA ("small" worm phenotype) and MAD family ("Mothers Against Decapentaplegic") of genes in Drosophila. There are three distinct sub-types of Smads: receptor-regulated Smads , common partner Smads (Co-Smads), and inhibitory Smads . The eight members of the Smad family are ...
