| Carr, Francis | <person> British chemist, *1874. See: Carr-Price reaction. (05 Mar 2000) |
|---|---|
| Carr-Price reaction | The reaction of antimony trichloride with vitamin A to yield a brilliant blue colour; this reaction forms the basis of several quantitative techniques for the determination of vitamin A. (05 Mar 2000) |
| Carr-Price test | A quantitative test for vitamin A based on the reaction with antimony trichloride in chloroform. (05 Mar 2000) |
| Carr-Purcell experiment | In magnetic resonance, the multiple spin echo technique. (05 Mar 2000) |
| carrageenan | <plant biology> Sulphated cell wall polysaccharide found in certain red algae. Contains repeating sulphated disaccharides of galactose and (sometimes) anhydrogalactose. It is used commercially as an emulsifier and thickener in foods and is also used to induce an inflammatory lesion when injected into experimental animals (probably activates complement). (18 Nov 1997) |
| carre-four sensitif | A term given by Charcot to the posterior portion of the caudal limb of the internal capsule. Origin: Fr. Sensory crossroads (05 Mar 2000) |
| Carrel's treatment | Treatment of wound surfaces by intermittent flushing with Dakin's solution. Synonym: Dakin-Carrel treatment. (05 Mar 2000) |
| Carrel, Alexis | <person> French-U.S. Surgeon and Nobel laureate, 1873-1944. See: Carrel's treatment, Carrel-Lindbergh pump, Dakin-Carrel treatment. (05 Mar 2000) |
| Carrel-Lindbergh pump | A perfusion device designed for use in culture of whole organs. (05 Mar 2000) |
| carrier | 1. <genetics, microbiology> An individual who does not display the symptoms of a disease, but harbors the pathogen which causes it, or has the gene (or genes) for it, and can transmit the disease to others either through interacting with other individuals, or by passing the disease-causing gene (or genes) to offspring. 2. <pharmacology> A substance which transports things, such as a carrier protein. (09 Oct 1997) |
| carrier cell | <cell biology> A cell that is capable of phagocytosis. The main mammalian phagocytes are neutrophils and macrophages. Origin: L. Phagedaena, Gr Phago, To eat. (18 Nov 1997) |
| carrier electrophoresis | Electrophoresis done on a carrier (such as paper, polyacrylamide gel, etc.). (05 Mar 2000) |
| carrier protein | <protein> A protein which transports specific substances through the cell membrane in which it is embedded and into the cell. Different carrier proteins are required to transport different substances, as each one is designed to recognise only one substance, or group of similar substances. (09 Oct 1997) |
| carrier proteins | Transport proteins that carry specific substances in the blood or across cell membranes. (12 Dec 1998) |
| carrier screening | Indiscriminate examination of members of a population to detect heterozygotes for serious disorders and counsel about the risks of marriages with other carriers, and by antenatal diagnosis where a married couple are both carriers; often sacrifices precision to simplicity and is most effectively applied to populations known to be at high risk.
