Definitions of SEDIMENTATION TEST
Sort: Oldest first
(1) Agglutination test, Widal's test (in the case of typhoid fever); (2) the employment in gastric roentgenology of a non-suspended mixture of a contrast salt, such as barium or bismuth, in water; the salt sediments rapidly and can be spread over all parts of the stomach wall, thus giving information as to shape and movement of the organ, and also bringing into view lesions on the anterior or posterior wall invisible when the stomach is full.

ATP Binding Cassette, Sub Family B Proteins
- A subfamily transmembrane the superfamily TRANSPORTERS that closely related in GLYCOPROTEIN. When overexpressed, function as dependent efflux pumps able extrude lipophilic drugs, especially ANTINEOPLASTIC AGENTS, from cells causing resistance (DRUG RESISTANCE, MULTIPLE). Although P-Glycoproteins share functional similarities to MULTIDRUG RESISTANCE-ASSOCIATED PROTEINS they are two distinct subclasses of ATP-BINDING CASSETTE TRANSPORTERS, and have little sequence homology.
