| one-carbon group transferases | <enzyme> A subclass of transferases that transfer chemical groups containing a single carbon. These include the methyltransferases, the hydroxymethyl and formyl transferases, the carboxyl and carbamoyl transferases, and the amidinotransferases. Registry number: EC 2.1 (12 Dec 1998) |
|---|---|
| taxonomic group | <zoology> A taxon with all its subordinate taxa and their individuals, for example the taxonomic group Insecta consists of all insects and their taxa. (09 Jan 1998) |
| T group | <abbreviation> Training group. (05 Mar 2000) |
| therapeutic group | Any group of patients meeting together for mutual psychotherapeutic, personal development, and life change goals. (05 Mar 2000) |
| encounter group | A form of psychological sensitivity training that emphasizes the experiencing of individual relationships within the group and minimises intellectual and didactic input; the group focuses on the present rather than concerning itself with the past or outside problems of its members. See: sensitivity training group. (05 Mar 2000) |
| training group | Any group emphasizing training in self-awareness and group dynamics. See: sensitivity training group. (05 Mar 2000) |
| ethnic group | A social group characterised by a distinctive social and cultural tradition maintained from generation to generation, a common history and origin and a sense of identification with the group; members of the group have distinctive features in their way of life, shared experiences and often a common genetic heritage; these features may be reflected in their experience of health and disease. (05 Mar 2000) |
| experimental group | A group of subjects exposed to the variable of an experiment, as opposed to the control group. (05 Mar 2000) |
| K blood group | K blood group See Kell blood group, Blood Groups appendix. (05 Mar 2000) |
| Kell blood group | <haematology, immunology> Blood type classification based on a group of erythrocyte antigens that is characterised by an antibody called anti-K. Multiple erythrocytic antigens that comprise at least three pairs of alternates and amorphs, determined by one complex gene or possibly several genes at closely linked loci. The system is important in transfusion reactions. Its expression involves the X chromosome. (21 Jun 2000) |
| family group | <zoology> The highest-ranking group of taxa whose names are regulated. The family group includes taxa at the ranks of superfamily, family, subfamily, tribe, and any other rank below superfamily and above the genus group that may be required, such as subtribe (09 Jan 1998) |
| ketole group | Carbons 1 and 2 of a 2-ketose (HOCH2CO-); trans-ketolation from d-xylose 5-phosphate to C-1 of aldoses is important in various metabolic pathways involving carbohydrates (e.g., photosynthesis, Dickens shunt); the two-carbon unit is transferred as a,beta-dihydroxyethyl thiamin pyrophosphate. (05 Mar 2000) |
| Kidd blood group | See Blood Groups appendix. (05 Mar 2000) |
| kidd blood-group system | A group of antigens consisting principally of jk(a) and jk(b), determined by allelic genes. Amorphs are encountered. Antibodies of these substances are usually weak and quite labile, stimulated by erythrocytes. (12 Dec 1998) |
| uukuniemi group viruses | A group of viruses in the genus phlebovirus of the family bunyaviridae, infecting vertebrates and vectored by ticks. Its members have not been associated with human disease though antibodies have been isolated from human sera. (12 Dec 1998) |
