| NADPH dehydrogenase (quinone) | A flavoprotein similar to NADH dehydrogenase (quinone), but oxidizing NADPH. Synonym: DT-diaphorase, menadione reductase, phylloquinone reductase, quinone reductase. (05 Mar 2000) |
|---|---|
| NADPH diaphorase | <enzyme> A flavoprotein that reversibly oxidises NADPH to NADP and a reduced acceptor. Chemical name: NADPH:(acceptor) oxidoreductase Registry number: EC 1.6.99.1 (12 Dec 1998) |
| NADPH oxidase | <enzyme> A plasma membrane-associated enzyme complex that catalyses the univalent reduction of oxygen using NADPH as an electron donor. The superoxide anion formed acts as an oxidant in the phagocyte microbicidal system, proceeding through a series of electron transfer reactions that form the respiratory burst. Various genetic defects in the system result in chronic granulomatous disease (granulomatous disease, chronic). Registry number: EC 1.6.- (12 Dec 1998) |
| NADPH-cytochrome c2 reductase | <enzyme> An enzyme catalyzing the reduction of 2 ferricytochrome c2 to 2 ferrocytochrome c2 at the expense of NADPH. Synonym: cytochrome c2 reductase. (05 Mar 2000) |
| NADPH-ferrihemoprotein reductase | <enzyme> A flavoprotein that catalyses the reduction of haem-thiolate-dependent monooxygenases and is part of the microsomal hydroxylating system. Its physiological acceptor is probably cytochrome p-450. Chemical name: NADPH:ferrihemoprotein oxidoreductase Registry number: EC 1.6.2.4 (12 Dec 1998) |
| NADPH-tetrazolium reductase | <enzyme> Reported to possess activity identical with NADPH cytochrome c reductase EC 1.6.2.4 Registry number: EC 1.6.2.- Synonym: NADPH-neotetrazolium reductase, NADPH-nbt reductase (26 Jun 1999) |
| nadroparin | <chemical> A heparin fraction with a mean molecular weight of 4500 daltons. It is isolated from porcine mucosal heparin and used as an antithrombotic agent. Pharmacological action: anticoagulant, fibrinolytic agent. (12 Dec 1998) |
| Naegeli syndrome | <syndrome> Reticular skin pigmentation, diminished sweating, hypodontia, and hyperkeratosis of the palms and soles; may be confused with incontinentia pigmenti but is as common in males as in females; autosomal dominant inheritance. Synonym: Franceschetti-Jadassohn syndrome. (05 Mar 2000) |
| Naegeli type of monocytic leukaemia | A variant of granulocytic leukaemia with monocytosis in the peripheral blood. Synonym: Naegeli type of monocytic leukaemia. (05 Mar 2000) |
| Naegeli, Oskar | <person> Swiss physician, 1885-1959. See: Naegeli syndrome. (05 Mar 2000) |
| Naegeli, Otto | <person> Swiss physician, 1871-1938. See: Naegeli type of monocytic leukaemia. (05 Mar 2000) |
| naegleria | A free-living soil amoeba pathogenic to humans and animals. It occurs also in water and sewage. The most commonly found species in man is naegleri fowleri which is the pathogen for primary amebic meningoencephalitis in primates. (12 Dec 1998) |
| naegleria fowleri | A species of parasitic protozoa having both an ameboid and flagellate stage in its life cycle. Infection with this pathogen produces primary amebic meningoencephalitis. (12 Dec 1998) |
| Naegleria gruberi | <protozoa> A normally amoeboid protozoan found in the soil. When it is flooded with water or a solution of low ionic strength it transforms into a swimming form with two flagella. (13 Nov 1997) |
| naevus | <dermatology, tumour> Tumour like but nonneoplastic hamartoma of skin. A vascular naevus is a localised capillary rich area of the skin (strawberry birthmark, sometimes the much more extensive port wine stain). A mole benign melanoma) is a pigmented naevus, a cluster of melanocytes containing melanin. (13 Nov 1997) |
