| CVS | cardiovascular surgery; cardiovascular system; challenge virus strain; chorionic villi sampling; cle... |
| HDCS | human diploid cell strain |
| LBS | low back syndrome; lumbar back strain |
| 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) |
| acetyl value | The milligrams of KOH required to neutralise the acetic acid produced by the hydrolysis of 1 g of acetylated fat; a measure of the hydroxy acids present in glycerides; notably high in castor oil. (05 Mar 2000) |
| beta, or beta-value | <radiobiology> Ratio of plasma kinetic pressure to magnetic-field pressure, proportional to the ratio of plasma kinetic energy density to magnetic field energy density. Beta is usually measured relative to the total, local field (loosely called beta toroidal), but sometimes the plasma pressure relative to only the poloidal component of the field (beta poloidal) or relative to some external field (like the maximum field at the magnetic coils) is more useful. There is also a normalised beta (beta_N) of interest when discussing the beta limit. (lots of help from Art Carlson with the above.) Because the cost of a reactor is strongly influenced by the strength of the magnetic field that must be provided, beta values are directly related to the economics of fusion power production. Beta is usually expressed as a percentage, with 5% generally believed to be the minimum value required for an economical fusion reactor. See: pressure, kinetic pressure, magnetic pressure, second stability. (09 Oct 1997) |
| biological value | <nutrition> The nutritional value of a protein, usually measured in comparison to the nutritional value of egg protein, which is the highest possible (BV=0.9 - 1.00). (21 Mar 1998) |
