| heat-labile | Destroyed or altered by heat. (05 Mar 2000) |
|---|---|
| plasma labile factor | <chemical> Heat- and storage-labile plasma glycoprotein which accelerates the conversion of prothrombin to thrombin in blood coagulation. Factor v accomplishes this by forming a complex with factor xa, phospholipid, and calcium (prothrombinase complex). Deficiency of factor v leads to owren's disease. Chemical name: Blood-coagulation factor V (12 Dec 1998) |
| labile | 1. Gliding, moving from point to point over the surface, unstable, fluctuating. 2. <chemistry> Chemically unstable. Origin: L. Labilis = unstable, from labi = to glide (18 Nov 1997) |
| labile affect | The rapid shifts in outward emotional expressions; often associated with organic brain syndromes such as intoxication. (05 Mar 2000) |
| labile current | An electrical current applied to the body by means of electrodes that are constantly shifted about. (05 Mar 2000) |
| labile elements | Tissue cells, as of epithelium, connective tissue, etc., that continue to multiply by mitosis during the life of the individual. (05 Mar 2000) |
| labile factor | <chemical> Heat- and storage-labile plasma glycoprotein which accelerates the conversion of prothrombin to thrombin in blood coagulation. Factor v accomplishes this by forming a complex with factor xa, phospholipid, and calcium (prothrombinase complex). Deficiency of factor v leads to owren's disease. Chemical name: Blood-coagulation factor V (12 Dec 1998) |
| labile hypertension | Frequently changing levels of elevated blood pressure. (05 Mar 2000) |
| labile pulse | Frequent changes in pulse rate. (05 Mar 2000) |
| heat-shock protein | <cell biology, molecular biology, protein> Families of proteins conserved through prokaryotic and eukaryotic cells and bacteria in response to hyperthermia and other environmental stresses, although some are constitutively expressed. They increase thermal tolerance and perform functions essential to cell survival under these conditions. Some serve to stabilise proteins in abnormal configurations, play a role in folding and unfolding of proteins and the assembly of oligomeric complexes and may act as chaperonins. Hsp90 complexes with inactive steroid hormone receptor and is displaced upon ligand binding. Four major sub classes are recognised: hsp90, hsp70, hsp60 and small hsps. Hsps have been suggested to act as major immunogens in many infections. Acronym: HSP (12 Dec 1998) |
| heat-shock protein 27 kinase | <enzyme> Phosphorylates hsp 26 on serine residues when stimulated by tumour necrosis factor or interleukin 1 Registry number: EC 2.7.1.- Synonym: hsp 27 kinase, heat-shock protein 27 kinase, hsp27 kinase (26 Jun 1999) |
| drosophila heat-shock protein | <protein> Proteins which are immediately produced when the Drosophila fruit fly is exposed for a short time to extreme heat or other stress, such as toxic substances or alcohol. (09 Oct 1997) |
| atomic heat | The amount of heat required to raise an atom from 0 |
| radiant heat | Heat given off from any body in the form of waves, similar to light waves but of greater wavelength. (05 Mar 2000) |
| molar heat capacity | <chemistry> The amount of energy required to raise the temperature of one mole of a substance by one degree Celsius (or Kelvin). (09 Jan 1998) |
