| 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.

| suprahisian block | Atrioventricular conduction delay occurring above, or cephalad to, the bundle of His. (05 Mar 2000) |
| density-dependent | <epidemiology> 1. Effects whose intensity changes with increasing population density. 2. Effects whose intensity increases with increasing population density, for example a mortality which becomes very high near a carrying capacity. Effects which become less pronounced at higher population sizes (perhaps the reduction in fecundity caused by the difficulty of mating) are sometimes called inverse density dependent. Density dependent effects are often a cause of nonlinearity in a model. (05 Dec 1998) |
| density dependent inhibition of growth | <cell culture> The phenomenon exhibited by most normal (anchorage dependent) animal cells in culture that stop dividing once a critical cell density is reached. The critical density is considerably higher for most cells than the density at which a monolayer is formed, for this reason, most cell behaviourists prefer the term density dependent inhibition of growth as this avoids any confusion with contact inhibition of locomotion, a totally different phenomenon that is contact dependent.

| dependent | Exhibiting dependence or dependency. (18 Nov 1997) |
| dependent beat | <cardiology, physiology> An extrasystole supposedly precipitated in some way by the preceding normal beat to which it is coupled, an extrasystole caused by artificial stimulation of the heart. Synonym: dependent beat. (05 Mar 2000) |
| dependent drainage | Drainage from the lowest part and into a receptacle at a level lower than the structure being drained. Synonym: downward drainage. (05 Mar 2000) |
| dependent oedema | A clinically detectable increase in extracellular fluid volume localised in a dependent area, as of a limb, characterised by swelling or pitting. (05 Mar 2000) |
| dependent personality | A personality in which a person passively allows others to assume responsibility for making decisions affecting him/her, characterised by a lack of self-confidence and an inability to function independently. (05 Mar 2000) |
| dependent personality disorder | An individual who fears separation and engaging othhers to assume responsibility (27 Sep 1997) |
| dependent variable | In experiments, a variable that is influenced by or dependent upon changes in the independent variable; e.g., the amount of a written passage retained (dependent variable) as a function of the different numbers of minutes (independent variable) allowed to study the passage. (05 Mar 2000) |
| depolarising block | <physiology> Skeletal muscle paralysis associated with loss of polarity of the motor endplate, as occurs following administration of succinylcholine. (05 Mar 2000) |
| diabetes mellitus, insulin-dependent | Diabetes mellitus characterised by insulin deficiency, sudden onset, severe hyperglycaemia, rapid progression to ketoacidosis, and death unless treated with insulin. The disease may occur at any age, but is most common in childhood or adolescence. (12 Dec 1998) |
| diabetes mellitus, non-insulin-dependent | Diabetes characterised by the ability to survive without ketoacidosis in the absence of insulin therapy. It is usually of slow onset and patients exhibit a tendency to obesity. (12 Dec 1998) |
| DNA-dependent ATPase | <enzyme> Factor y is a phage 174 specific DNA-dependent atpase; atpase I can act with double-stranded DNA; atpase II and III require single-stranded DNA; a18r from vaccinia virus Registry number: EC 3.6.1.- Synonym: DNA helicase II, factor y, DNA-dependent atpase I, DNA-dependent atpase II, DNA-dependent atpase III, rep protein (E coli), atpase, DNA-dependent, DNA-dependent atpase iv, uvrd protein, rep helicase, pri a protein, protein n', rip100, pria helicase, pria protein (helicase), a18r gene product, DNA helicase a (26 Jun 1999) |
