| specific therapy | Therapy aimed at the cause(s) of a disease process, as opposed to symptomatic therapy. (05 Mar 2000) |
| specific transduction | Transduction in which the bacteriophage strain is able to transfer only some, or only one, of the donor bacterium genes. Synonym: specific transduction. (05 Mar 2000) |
| specific urethritis | An obsolete term for gonorrhoea. (05 Mar 2000) |
| N(2),N(2)-dimethylguanosine-specific tRNA methyltransferase | <enzyme> Responsible for the modification of both mitochondrial and cytoplasmic trnas Registry number: EC 2.1.1.- Synonym: dmg trna methyltransferase (26 Jun 1999) |
| sporulation-specific cell wall hydrolase | <enzyme> From bacillus subtilis; 255-amino acid protein mw 27.146 kD; hydrolyzes both vegetative cell walls and spore peptidoglycan genbank d14666 Registry number: EC 3.- Synonym: cwlc gene product (26 Jun 1999) |
| non-specific | 1. Not due to any single known cause, as to a particular pathogen. 2. Not directed against a particular agent, but rather having a general effect, as non-specific therapy. (18 Nov 1997) |
| non-specific anergy | A reduction of the normal or usual immunologic responses because of unrelated intervening disease. Synonym: non-specific anergy. (05 Mar 2000) |
| non-specific cholinesterase | <enzyme> An enzyme that breaks down acetylcholine tostop its action. (22 May 1997) |
| non-specific protein | A protein substance that elicits a response not mediated by specific antigen-antibody reaction. (05 Mar 2000) |
| non-specific system | <physiology> A physiological term denoting that part of the brainstem reticular formation that plays a central role in the organism's bodily and behavorial alertness. It extends as a diffusely organised neural apparatus through the central region of the brainstem into the subthalamus and the intralaminar nuclei of the thalamus; by its ascending connections it affects the function of the cerebral cortex in the sense of behavioural responsiveness; its descending (reticulospinal) connections transmit its activating influence upon bodily posture and reflex mechanisms (e.g., muscle tonus), in part by way of the gamma motor neurons. See: reticular formation. Synonym: non-specific system. (05 Mar 2000) |
| non-specific therapy | The injection of a foreign protein, typhoid vaccine, etc., to induce fever in the treatment of certain diseases, especially those of a parasyphilitic nature. Synonym: phlogotherapy. (05 Mar 2000) |
| non-specific urethritis | Urethritis not resulting from gonococcal, chlamydial, or other specific infectious agents. Synonym: simple urethritis. (05 Mar 2000) |
| non-specific vaginitis | bacterial vaginosis |
| sugar-non-specific nuclease | <enzyme> An exocytoplasmic sugar-non-specific nuclease that is able to degrade linear or covalently closed circular double-stranded DNA as well as single-stranded DNA or RNA; from cyanobacterium anabaena; mw 29 kD; amino acid sequence has been determined Registry number: EC 3.1.- Synonym: nuca gene product, anabaena (26 Jun 1999) |
