| oligomeganephronia | <radiology> Aka: oligonephronic hypoplasia, form of renal hypoplasia, very small kidneys, reduced number of renal segments (less than7), most severe form unipapillary kidney, hypertrophied nephrons, male:female 3:1 (Pollack), progressive renal failure, poor excretion on IVU, normal or mildly dilated collecting systems (12 Dec 1998) |

| oligomenorrhoea | <gynaecology> Infrequent menstruation with markedly diminished menstrual flow, relative amenorrhoea. (15 Nov 1997) |
| oligomer | <chemistry> A molecule consisting of just a few monomers. (09 Oct 1997) |
| oligomeric protein | <biochemistry> A protein where two or more of its units are identical polypeptide chains. (09 Oct 1997) |
| oligomerisation | <chemistry> The chemical process of creating oligomers from larger or smaller molecules. (09 Oct 1997) |
| oligomerous | <botany> Having few members in each set of organs; as, an oligomerous flower. Origin: Oligo- + Gr. Part. Source: Websters Dictionary (01 Mar 1998) |
| oligomorphic | Presenting few changes of form; not polymorphic. Origin: oligo-+ G. Morphe, form (05 Mar 2000) |
| oligomycin | <microbiology> A bacterial toxin inhibitor of oxidative phosphorylation that acts on a small subunit of the F1 ATPase. (18 Nov 1997) |
| oligomycin sensitivity conferral protein | <protein> The _ subunit of the ATP synthase, believed to link the F1 catalytic segment to the F0 proton conduction segment. Binds the toxin oligomycin. (18 Nov 1997) |
| oligomycins | <chemical> A closely related group of toxic substances elaborated by various strains of streptomyces. They are 26-membered macrolides with lactone moieties and double bonds and inhibit various atpases, causing uncoupling of phosphorylation from mitochondrial respiration. Used as tools in cytochemistry. Some specific oligomycins are rutamycin, peliomycin, and botrycidin (formerly venturicidin x). Pharmacological action: antibiotics, macrolide, enzyme inhibitors, uncoupling agents. (12 Dec 1998) |
| oligomyold | <anatomy, ornithology> Having few or imperfect syringeal muscles; said of some passerine birds (Oligomyodi). Origin: Oligo- + Gr, a muscle. Source: Websters Dictionary (01 Mar 1998) |
| oligonephronic | Characterised by a reduced number of nephrons. (05 Mar 2000) |
| oligonucleotidase | <enzyme> From flammulina veluptis; catalyses exonucleolytic cleavage of oligonucleotides to yield 5'-phosphomononucleotides; also hydrolyzes nad+ to nmn and AMP; formerly EC 3.1.4.19 Registry number: EC 3.1.13.3 (26 Jun 1999) |
| oligonucleotide | <biochemistry> Linear sequence of up to 20 nucleotides joined by phosphodiester bonds. Above this length the term polynucleotide begins to be used. (18 Nov 1997) |
| oligonucleotide probes | Synthetic or natural oligonucleotides used in hybridization studies in order to identify and study specific nucleic acid fragments, e.g., DNA segments near or within a specific gene locus or gene. The probe hybridises with a specific mRNA, if present. Conventional techniques used for testing for the hybridization product include dot blot assays, southern blot assays, and DNA:RNA hybrid-specific antibody tests. Conventional labels for the probe include the radioisotope labels 32p and 125i and the chemical label biotin. (12 Dec 1998) |
