| mastectomy, extended radical | Radical mastectomy with removal of the ipsilateral half of the sternum and a portion of ribs two through five with the underlying pleura and the internal mammary lymph nodes. (12 Dec 1998) |
|---|---|
| mastectomy, modified radical | Total mastectomy with axillary node dissection, but with preservation of the pectoral muscles. (12 Dec 1998) |
| mastectomy, radical | Removal of the breast, pectoral muscles, axillary lymph nodes, and associated skin and subcutaneous tissue. (12 Dec 1998) |
| 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) |
| alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid | <chemical> Alpha-amino-2,3-dihydro-5-methyl-3-oxo-4-isoxazolepropanoic acid. An ibotenic acid homolog and glutamate agonist. The compound is the defining agonist for the ampa subtype of glutamate receptors (receptors, ampa). It has been used as a radionuclide imaging agent but is more commonly used as an experimental tool in cell biological studies. Pharmacological action: excitatory amino acid agonists. Chemical name: 4-Isoxazolepropanoic acid, alpha-amino-2,3-dihydro-5-methyl-3-oxo- (12 Dec 1998) |
| beta-hydroxy-beta-methylglutaryl-CoA | -OOCCH2C(OH)(CH3)CH2COS-CoA;a key intermediate in the synthesis of ketone bodies and of steroids. Synonym: 3-hydroxy-3-methylglutaryl-CoA. Beta-hydroxy-beta-methylglutaryl-lyase, an enzyme, found primarily in liver and rumen epithelium that catalyses the formation of acetyl-CoA and acetoacetate from beta-hydroxy-beta-methylglutaryl-CoA; a key step in ketogenesis; a deficiency of this enzyme leads to episodes of severe metabolic acidosis without ketosis. Beta-hydroxy-beta-methylglutaryl-reductase, an enzyme that catalyses the rate-limiting step of cholesterol biosynthesis, beta-hydroxy-beta-methylglutaryl-CoA + 2NADPH + 2H+ → mevalonate + 2NADP+ + coenzyme A. Beta-hydroxy-beta-methylglutaryl-synthase, an enzyme in mitochondria that catalyses the reaction of acetyl-CoA with acetoacetyl-CoA and water to form beta-hydroxy-beta-methylglutaryl-CoA and coenzyme A, a step required for both ketogenesis and steroidogenesis to occur. (05 Mar 2000) |
| calcium hydroxy apatite | <radiology> All calcification in soft tissues is hydroxyapatite, except cartilage (chondrocalcinosis): calcium pyrophosphate see also: Milwaukee shoulder (12 Dec 1998) |
| chromatin 3'-phosphatase-5'-hydroxy kinase | <enzyme> Hydrolyzes the 3'-phosphate end of a polynucleotide duplex followed by ATP-mediated phosphorylation of the 5'-oh end Registry number: EC 3.1.3.- Synonym: chromatin-phosphatase-hydroxykinase (26 Jun 1999) |
| S-adenosyl-L-methionine-2-octaprenyl-3-methyl-5-hydroxy-6-methoxy-1,4-benzoquinone-O-methyltransferase | <enzyme> Proposed pathway for final reaction in ubiquinone biosynthesis. Registry number: EC 2.1.1.- Synonym: 2-octaprenyl-3-methyl-5-hydroxy-6-methoxy-1,4-benzoquinone methyltransferase, ubig gene product, ubig protein (26 Jun 1999) |
| hydroxy- | <chemistry, prefix> A combining form, also used adjectively, indicating hydroxyl as an ingredient. <chemistry> Hydroxy acid, an organic acid, having (besides the hydroxyl group of the carboxyl radical) an alcoholic hydroxyl group, and thus having the qualities of an alcohol in addition to its acid properties; as, lactic and tartaric acids are hydroxy acids. (29 Oct 1998) |
