D factor
| stock strain | A bacterial or other microbial strain that has been maintained under laboratory conditions as representative of its type. (05 Mar 2000) |
|---|---|
| strain | A tearing injury to muscle. Usually causes some degree of bleeding within the muscle tissue (haematoma). (27 Sep 1997) |
| strain birefringence | <chemistry> Optical property of a material in which the refractive index is different for light polarized in one plane compared to the orthogonal plane. May arise from molecular organisation of the material (form birefringence.), alignment of molecules due to tension (stress birefringence.) or alignment of rod like particles in flow (flow birefringence). With crossed Nicoll prisms a birefringent material appears bright against a dark background. (19 Jan 1998) |
| strain development | Improving the genetics of an organism so that it carries out a biotechnological process more effectively. (14 Nov 1997) |
| strain fracture | The tearing off, by a sudden force, of a piece of bone attached to a tendon, ligament, or capsule; the force may be exogenous or endogenous. (05 Mar 2000) |
| strain gauge | A device, employing the Wheatstone bridge principle, used for accurate measurement of forces such as strain, stress, or pressure. (05 Mar 2000) |
| stress-strain curve | A curve showing the ratio of deformation to load during the testing of a material in tension. (05 Mar 2000) |
| inbred strain | Any strain of animal or plant obtained by a breeding strategy that tends to lead to homozygosity. Such breeding strategies include brother sister mating and back crossing of offspring with parents. See: congenic. (18 Nov 1997) |
| isogenic strain | A strain of animals inbred for many generations and with high probability homozygous for certain specified genes. (05 Mar 2000) |
| type strain | The nomenclatural type of a species or subspecies. (05 Mar 2000) |
| Flury strain rabies virus | <organism, virology> Species of the Rhabdoviridae that causes rabies in humans. The virus infects the cells in the brain, causing a fatal encephalomyelitis. It is found all over the world, but strict quarantine regulations have excluded it from Britain and Australia. The virus infects a number of domestic and wild mammals, whose saliva is infective. Some bats and small mammals can carry the virus without showing any symptoms of disease. (18 Nov 1997) |
| Flury strain vaccine | An inactivated virus vaccine, used for preexposure immunization to persons at high risk of exposure, e.g., veterinarians, and in conjunction with rabies immunoglobulin, for postexposure prophylaxis. The official preparation is human diploid cell vaccine produced from rabies virus grown in cultures of human diploid embryo lung cells and inactivated with propriolactone. It has a much lower incidence of adverse reactions than the previously used duck embryo vaccine. (12 Dec 1998) |
| lysogenic strain | A strain of bacterium that is infected with a temporate bacteriophage. See: lysogeny. (05 Mar 2000) |
| ankle joint | The joint that is formed by the inferior articular and malleolar articular surfaces of the tibia, the malleolar articular surface of the fibula, and the medial malleolar, lateral malleolar, and superior surfaces of the talus. (12 Dec 1998) |
| anterior intraoccipital joint | Cartilaginous union in the newborn between the lateral and the basilar portions of the occipital bone. Synonym: synchondrosis intraoccipitalis anterior, anterior intraoccipital joint. (05 Mar 2000) |
