| modified radical hysterectomy | An extended hysterectomy in which a portion of the upper vagina is removed; the ureters are exposed and pulled back laterally without dissection from the ureteral bed. Synonym: TeLinde operation. (05 Mar 2000) |
|---|---|
| modified radical mastectomy | <procedure, surgery> The most common type of mastectomy. Breast skin, nipple, areola and underarm lymph nodes are removed. The chest muscles are saved. (09 Oct 1997) |
| colour radical | The part of a visibly coloured molecule responsible for light absorption over a range of wavelengths thus giving rise to the colour. By extension the term may be applied to UV or IR absorbing parts of molecules. Do not confuse with chromatophores. (18 Nov 1997) |
| hydroxyl radical | <chemical> Hydroxyl. The univalent radical oh. This radical is characteristic of hydroxides, oxygen acids, alcohols, glycols, phenols, and hemiacetals. Chemical name: Hydroxyl (12 Dec 1998) |
| oxygen radical | <chemistry> Any oxygen species that carries an unpaired electron (except free oxygen). Examples are the hydroxyl radical and the superoxide anion. These radicals are very powerful oxidizing agents and cause structural damage to proteins and nucleic acids. They mediate the damaging effects of ionising radiation. (18 Nov 1997) |
| extended radical mastectomy | Excision of the entire breast including the nipple, areola, and overlying skin, as well as the pectoral muscles and the lymphatic-bearing tissues of the axilla and chest wall and internal mammary chain of lymph nodes. (05 Mar 2000) |
| free radical | A chemically active atom or molecular fragment containing a chemical charge due to an excess or deficient number of electrons. Radicals seek to receive or release electrons in order to achieve a more stable configuration, a process that can damage the large molecules within cells. See: Oxidation. (09 Oct 1997) |
| free radical reductase | <enzyme> Catalyses conversion of carbon-centreed lipid radicals into an inactive species by utilizing vitamin e at one end and glutathione at the other Registry number: EC 1.8.4.- (26 Jun 1999) |
| free radical scavengers | Substances that influence the course of a chemical reaction by ready combination with free radicals. Among other effects, this combining activity protects pancreatic islets against damage by cytokines and prevents myocardial and pulmonary perfusion injuries. (12 Dec 1998) |
| absolute alcohol | Water having been removed. Synonym: anhydrous alcohol. (05 Mar 2000) |
| acyclic monoterpene primary alcohol - NADP oxidoreductase | <enzyme> From catmint nepeta racemosa; involved in the biosynthesis of iridoid monoterpenes; oxidises geraniol, nerol, and their 10-hydroxy derivatives in the presence of nadp(+). Registry number: EC 1.1.1.- Synonym: monoterpene primary alcohol - nadp oxidoreductase, ampano (26 Jun 1999) |
| alcohol | <chemical> An organic chemical containing one or more hydroxyl groups. Alcohols can be liquids, semisolids or solids at room temperature. Common alcohols include ethanol (the type found in alcoholic beverages) methanol (found in methylated spirit and can cause blindness and other nervous system damage if ingested) and propanol. (06 May 1997) |
| alcohol acid | A group of compounds that contain both the carboxyl and hydroxy radicals; e.g., glycolic acid. (05 Mar 2000) |
| alcohol addiction | <disease> A disorder characterised by pathological pattern of alcohol use that causes a serious impairment in social or occupational functioning. In DSN III R this is termed alcohol abuse or, if tolerance or withdrawal is present, alcohol dependence. (18 Nov 1997) |
| alcohol amnestic disorder | <psychiatry> A mental disorder with brain damage characterised by amnesia, compensatory confabulation, disturbance of attention, and peripheral neuritis. It is usually associated with alcoholism and dietary deficiencies. (12 Dec 1998) |
