| immunologic and biological factors | A collective grouping for biologically active substances that play a role in the functioning of the immune system and those that show biological or physiological activity. (12 Dec 1998) |
|---|---|
| immunologic factors | Biologically active substances whose activities affect or play a role in the functioning of the immune system. (12 Dec 1998) |
| initiation factors | The set of catalytic proteins required, in addition to mRNA and ribosomes, for protein synthesis to begin. In bacteria three distinct proteins have been identified: if 1 (8 kD), IF 2 (75 kD) and IF 3 (30 kD). at least 6-8 proteins have been identified in eukaryotes. IFs 1 and 2 enhance the binding of initiator tRNA to the initiation complex. (18 Nov 1997) |
| ischemia-modifying factors | Various factors that play a role in determining the extent of necrosis with cerebral stroke; these include blood viscosity and osmolality, the blood pressure, and the anatomy of the neck and intracranial arteries. (05 Mar 2000) |
| oesophageal carcinoma risk factors | <radiology> P Plummer-Vinson Web, A achalasia, alcohol, B Barrett oesophagus, S stricture, T tylosis, tobacco see: oesophageal carcinoma (12 Dec 1998) |
| thyroid carcinoma risk factors | <radiology> Increased risk of malignancy: young female, male, history of radiation to head or neck, hard lesion, other neck masses, no shrinkage on TSH, family hx of thyroid carcinoma see: thyroid carcinoma (12 Dec 1998) |
| time factors | Elements of limited time intervals, contributing to particular results or situations. (12 Dec 1998) |
| transcription factors | Endogenous substances, usually proteins, which are effective in the initiation, stimulation, or termination of the genetic transcription process. (12 Dec 1998) |
| transcription factors, tfii | The so-called general transcription factors that bind to RNA polymerase II and that are required to initiate transcription. They include tfiia, tfiib, tfiid, tfiie, tfiif, tfiih, tfii-I, and tfiij. In vivo they apparently bind in an ordered multi-step process and/or may form a large preinitiation complex called RNA polymerase II holoenzyme. (12 Dec 1998) |
| transcription factors, tfiii | Factors that bind to RNA polymerase III and aid in transcription. They include the assembly factors tfiiia and tfiiic and the initiation factor tfiiib. All combine to form a preinitiation complex at the promotor that directs the binding of RNA polymerase III. (12 Dec 1998) |
| epidemiologic factors | Events, characteristics, or other definable entities that have the potential to bring about a change in a health condition or other defined outcome. (12 Dec 1998) |
| essential food factors | Those substances required in the diet: certain amino acids and unsaturated fatty acids, vitamins, essential minerals, etc. (05 Mar 2000) |
| Factors I XII | <haematology> Blood clotting factors, especially from humans. These factors form a cascade in which the activation of the first factor leads to enzymic attack on the next factor and so on, finally resulting in blood clotting. (18 Nov 1997) |
| uncoupling factors | Substances such as dinitrophenol that allow oxidation in mitochondria to proceed without the usual concomitant phosphorylation to produce ATP; these poisons thus "uncouple" oxidation and phosphorylation. Synonym: uncoupling factors. (05 Mar 2000) |
| lactose factors | Plasmids which determine the ability of a bacterium to ferment lactose. (12 Dec 1998) |
