| histiocytosis, non-langerhans-cell | Group of disorders which feature accumulations of active histiocytes and lymphocytes, but where the histiocytes are not langerhans cells. The group includes haemophagocytic lymphohistiocytosis, infection-associated haemophagocytic syndrome, sinus histiocytosis, xanthogranuloma, reticulohistiocytoma, juvenile xanthoma, xanthoma disseminatum, as well as the lipid storage diseases (sea-blue histiocyte syndrome and niemann-pick disease).

| nodular non-X histiocytosis | A rare recurring generalised eruption in adults of flesh coloured or erythematous papules remaining localised to the skin and consisting of dermal nodules of mononuclear histiocytes that do not stain for lipid. Synonym: nodular non-X histiocytosis. (05 Mar 2000) |
| non-arcon articulator | An articulator with the equivalent condylar guides attached to the lower member and the hinge axis to the upper member. (05 Mar 2000) |
| non compos mentis | Not of sound mind; mentally incapable of managing one's affairs. Origin: L. Non, not, + compos, participating, competent, + mens, gen. Mentis, mind (05 Mar 2000) |

| non-ego | <psychology> The union of being and relation as distinguished from, and contrasted with, the ego. See Ego. Origin: L, not I. Source: Websters Dictionary (01 Mar 1998) |
| non-haem iron protein | <biochemistry> Any protein containing iron but not any haem iron; e.g., NADH dehydrogenase. They are often found in oxidation-reduction reactions, and contain iron but no porphyrin groups. (17 Jul 2002) |
| non-Hodgkin's lymphoma | <oncology, tumour> A group of lymphomas which differ in important ways from Hodgkin's disease and are classified according to the microscopic appearance of the cancer cells. The disease is classified as either low grade (slowly growing), intermediate grade or high grade (rapidly growing) and may be treated in a variety of ways depending on the exact diagnosis. Previously called lymphosarcoma. (30 Sep 1997) |
| non-insulin-dependent diabetes mellitus | <disease> An often mild form of diabetes mellitus of gradual onset, usually in obese individuals over age 35; absolute plasma insulin levels are normal to high, but relatively low in relation to plasma glucose levels; ketoacidosis is rare, but hyperosmolar coma can occur; responds well to dietary regulation and/or oral hypoglycaemic agents, but diabetic complications and degenerative changes can develop. (05 Mar 2000) |
| non-ionic contrast media | <radiology> A class of radiographic contrast media which do not ionise in solution, thereby decreasing effective osmolarity and toxicity. (05 Mar 2000) |
| non-linear | Not linear. (05 Dec 1998) |
| non-Newtonian fluid | <chemistry, physics> A fluid in which the viscosity varies depending upon the shear stress. The effect can arise because of alignment of nonspherical molecules as flow is established or because of suspended deformable particles as in blood. It relates to a fluid in which flow and rate of shear are not always proportional to the applied stress and which does not obey Poiseuille's law. See: anomalous viscosity, Fahraeus-Lindqvist effect, Bingham plastic. Compare: newtonian fluid. (21 Jun 2000) |
| non-nucleated | <cell biology> Having no nucleus. (05 Mar 2000) |
| non-PKU hyperphenylalaninaemia | A benign phenotype in which phenylalanine monooxygenase is deficient but is greater than 1% of normal levels. (05 Mar 2000) |
| non-pros | To decline or fail to prosecute; to allow to be dropped (said of a suit); to enter judgment against (a plaintiff who fails to prosecute); as, the plaintiff was non-prossed. Origin: Nonprossed; Non-prossing. Source: Websters Dictionary (01 Mar 1998) |
