| 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) |
| deoxyribonucleases, type III site-specific | <enzyme> Enzyme systems composed of two subunits and requiring ATP and magnesium for endonucleolytic activity; they do not function as atpases. They exist as complexes with modification methylases of similar specificity. The systems recognise specific short DNA sequences and cleave a short distance, about 24 to 27 bases, away from the recognition sequence to give specific double-stranded fragments with terminal 5'-phosphates. Enzymes from different microorganisms with the same specificity are called isoschizomers. Registry number: EC 3.1.21.5 (12 Dec 1998) |
| deoxyribonucleases, type II site-specific | <enzyme> Enzyme systems containing a single subunit and requiring only magnesium for endonucleolytic activity. The corresponding modification methylases are separate enzymes. The systems recognise specific short DNA sequences and cleave either within, or at a short specific distance from, the recognition sequence to give specific double-stranded fragments with terminal 5'-phosphates. Enzymes from different microorganisms with the same specificity are called isoschizomers. Registry number: EC 3.1.21.4 (12 Dec 1998) |
| deoxyribonucleases, type I site-specific | <enzyme> Enzyme systems containing three different subunits and requiring ATP, s-adenosylmethionine, and magnesium for endonucleolytic activity to give random double-stranded fragments with terminal 5'-phosphates. They function also as DNA-dependent atpases and modification methylases, catalyzing the reactions of EC 2.1.1.72 and EC 2.1.1.73 with similar site-specificity. The systems recognise specific short DNA sequences and cleave at sites remote from the recognition sequence. Enzymes from different microorganisms with the same specificity are called isoschizomers. Registry number: EC 3.1.21.3 (12 Dec 1998) |
| IgA-specific serine endopeptidase | <enzyme> Extracellular microbial enzymes whose only substrate is human IgA of the iga1 subclass; cleave the immunoglobulin at a specific internal prolyl-threonyl peptide bond in the heavy chain to yield intact faba and fca fragments; consider also EC 3.4.24.13 Registry number: EC 3.4.21.72 Synonym: immunoglobulin a(1) protease, iga1 protease, immunoglobulin a1 protease, IgA protease (26 Jun 1999) |
| organ-specific | Denoting or pertaining to a serum produced by the injection of the cells of a certain organ or tissue that, when injected into another animal, destroys the cells of the corresponding organ. (05 Mar 2000) |
| organ-specific antigen | A heterogenetic antigen with organ specificity; e.g., in addition to species-specific antigen, kidney of one species contains antigen that is identical to that in kidney of other species. Synonym: tissue-specific antigen. (05 Mar 2000) |
| specific activity |

| specific |
Applied to a physical quantity, especially a thermodynamic variable, usually means per unit mass. For example, specific volume is volume divided by mass, specific enthalpy is enthalpy divided by mass, and so on. Specific quantities are common in meteorology, and hence specific is often omitted as a qualifier, it being understood.

| specific heat capacity |
(Or specific heat.) The heat capacity of a system divided by its mass. It is a property solely of the substance of which the system is composed. As with heat capacities, specific heats are commonly defined for processes occurring at either constant volume (c v ) or constant pressure (c p ). For an ideal gas, both are constant with temperature and related by c p = c v + R with R the gas constant. ...
