| hydro- | Hydr- 1. Water, watery. 2. Containing or combined with hydrogen. 3. A hydatid. Origin: G. Hydor, water (05 Mar 2000) |
| hydro-electric | Pertaining to, employed in, or produced by, the evolution of electricity by means of a battery in which water or steam is used. <physics> Hydro-electric machine, an apparatus invented by Sir William Armstrong of England for generating electricity by the escape of high-pressure steam from a series of jets connected with a strong boiler, in which the steam is produced. Origin: Hydro-, 1 + electric. Source: Websters Dictionary (01 Mar 1998) |
| hydro-lyases | <enzyme> Enzymes that catalyze the removal of water from a substrate by breakage of a carbon-oxygen bond, leading to formation of a double bond. The recommended name is usually dehydratase. The term synthase or hydratase is used when the reverse aspect of the reaction is dominant. Registry number: EC 4.2.1. (12 Dec 1998) |
| hydro-mulching | <botany> Seeding of grasses, mixed with fertiliser, a wood pulp mulch, and a tackifier to stick the mix to the ground, applied by a machine blower in a wet condition to exposed, denuded slopes or embankments. (if no mulch is used, it is called hydro-seeding.) (09 Oct 1997) |
| 4-oxalmesaconate hydro-lyase | <enzyme> Converts 4-oxalmesaconate ((e)-3-carboxy-5-oxo-2-hexenedioic acid) to 4-oxalcitramalate Registry number: EC 4.2.1.- Synonym: pseudomonas ochraceae enzyme i (26 Jun 1999) |
| vitamin B12 | <biochemistry> Member of the water soluble B vitamin group, important in the proper function of the nervous system and important in proper carbohydrate, protein and fat metabolism. (27 Sep 1997) |
| vitamin B12 absorption test | <investigation> This test measures the amount of vitamin B12 in the urine after ingesting a dose of B12. This test evaluates vitamin B12 absorption. The cells in the stomach produce a substance known as intrinsic factor. This substance combines with B12 to allow absorption in the distal ileum. The patient is given a small dose of radioactive B12 which can then be detected in the patients urine. Pernicious anaemia is the clinical result of B12 deficiency. Conditions that can result in an abnormal Schilling test include: deficiency of intrinsic factor, malabsorption or the development of an antibody to intrinsic factor. The Schilling test can be performed with or without administration of intrinsic factor to determine what the underlying cause for pernicious anaemia. Laxative use, renal insufficiency and hypothyroidism can all interfere with the results of this test. (27 Sep 1997) |
| vitamin B12 deficiency | A form of anaemia (low red blood cell counts) that results when the bone marrow fails to produce adequate numbers of red blood cells due to a deficiency in vitamin B12. Intrinsic factor, necessary for normal B12 absorption, may be the underlying cause for B12 deficiency if is not produced in the gastric glands (in the stomach). (27 Sep 1997) |
| vitamin B12 neuropathy | A subacute or chronic disorder of the spinal cord, such as that occurring in certain patients with vitamin B12 deficiency, characterised by a slight to moderate degree of gliosis in association with spongiform degeneration of the posterior and lateral columns. Synonym: combined sclerosis, combined system disease, funicular myelitis, Putnam-Dana syndrome, vitamin B12 neuropathy. (05 Mar 2000) |
| vitamin B12 with intrinsic factor concentrate | A combination of vitamin B12 with suitable preparations of the mucosa of the stomach or intestine of domestic animals used for food by humans. (05 Mar 2000) |
| coenzyme B12 | <biochemistry> A coenzyme derived from cobalamine which is involved in carbon skeletal rearrangements. It is the only biomolecule known that has a carbon-metal bond. (09 Oct 1997) |
| pseudovitamin B12 | <biochemistry> Cobamide cyanide phosphate, 3'-ester with 7-alpha-d-ribofuranosyladenine, inner salt; vitamin B12 with adenine replacing dimethylbenzimidazole; one of several substances produced during anaerobic fermentation by certain organisms in bovine rumen contents; it is chemically closely similar to vitamin B12 (cyanocobalamin) but without, in humans, the physiologic action of the vitamin.
