| colonisation factors | <microbiology> The pili on enteropathogenic forms of E. Coli facilitate adhesion of the bacteria to receptors (probably GM1 gangliosides) on gut epithelial cells and are often referred to as colonisation or adherence factors. Colonisation factor antigens may be plasmid coded, are essential for pathogenicity and are strain specific, for example K88 diarrhoea in piglets), CFAI and CFAII on strains causing similar disease in man.

|---|---|
| cord factors | Trehalose-6,6'-dimycolate. A toxic glycolipid of mycobacterium tuberculosis. Induces cellular biochemical disfunction in animals; used as immunoadjuvant. (12 Dec 1998) |
| myogenic regulatory factors | A family of muscle-specific transcription factors which bind to DNA in control regions and thus regulate myogenesis. All members of this family contain a conserved helix-loop-helix motif which is homologous to the myc family proteins. These factors are only found in skeletal muscle. Members include the myod protein (myod protein), myogenin, myf-5, and myf-6 (also called mrf4 or herculin). (12 Dec 1998) |
| coupling factors | Proteins that restore phosphorylating ability to mitochondria that have lost it, i.e., have become "uncoupled" so that oxidation and electron transport no longer produces ATP. Usually termed coupling factor F1, F2, etc. Synonym: C factors. (05 Mar 2000) |
| haemolysin factors | Plasmids controlling the synthesis of haemolysin by bacteria. (12 Dec 1998) |
| precipitating factors | Factors associated with the definitive onset of a disease, illness, accident, behavioural response, or course of action. Usually one factor is more important or more obviously recognizable than others, if several are involved, and one may often be regarded as "necessary". Examples include exposure to specific disease; amount or level of an infectious organism, drug, or noxious agent, etc. (12 Dec 1998) |
| predisposing factors | Attitudinal, personality, and related factors that motivate and guide an individual to take certain health actions. (05 Mar 2000) |
| sex factors | Maleness or femaleness as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or effect of a circumstance. It is used with human or animal concepts but should be differentiated from sex characteristics, anatomical or physiological manifestations of sex, and from sex distribution, the number of males and females in given circumstances. (12 Dec 1998) |
| socioeconomic factors | Social and economic factors that characterise the individual or group within the social structure. (12 Dec 1998) |
| steam conversion factors | (approximations) 1 pound of steam = 1,000 Btu = .3 kW. 10,000 lbs/hr steam = 300 boiler horsepower. (05 Dec 1998) |
| debranching factors | Enzyme's that bring about destruction of branches in glycogen; formerly considered to be one enzyme, now known to be a mixture of transferases (4-alpha-d-glucanotransferase) and hydrolases (amylo-1,6-glucosidase). Synonym: debranching factors. (05 Mar 2000) |
| suppressor factors, immunologic | Proteins, protein complexes, or glycoproteins secreted by suppressor T-cells that inhibit either subsequent T-cells, B-cells, or other immunologic phenomena. Some of these factors have both histocompatibility (I-j) and antigen-specific domains which may be linked by disulfide bridges. They can be elicited by haptens or other antigens and may be mass-produced by hybridomas or monoclones in the laboratory. (12 Dec 1998) |
| direct lytic factors | most abundant proteins in cobra (naja of the elapids) venom; basic polypeptides of 57 to 62 amino acids with four disulfide bonds and a molecular weight of less than 7000; causes skeletal and cardiac muscle contracture, interferes with neuromuscular and ganglionic transmission, depolarises nerve, muscle and blood cell membranes, thus causing haemolysis. Synonym: cobramine a; cobramine b; cobra cytotoxin; gamma toxin; membrane-active polypeptide. (12 Dec 1998) |
| 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) |
