  • (19) Essential characteristics of the composite bone cement included a homogeneous and uniform fiber distribution, and a minimal increase in apparent viscosity of the polymerizing cement.

Intrinsic


Definition:

  • (a.) Inward; internal; hence, true; genuine; real; essential; inherent; not merely apparent or accidental; -- opposed to extrinsic; as, the intrinsic value of gold or silver; the intrinsic merit of an action; the intrinsic worth or goodness of a person.
  • (a.) Included wholly within an organ or limb, as certain groups of muscles; -- opposed to extrinsic.
  • (n.) A genuine quality.

Example Sentences:

  • (4) Relative to the perceived severity of their asthma, both Maoris and Pacific Islanders lost more time from work or school and used hospital services more than European asthmatics using A & E. The increased use of A & E by Maori and Pacific Island asthmatics seemed not attributable to the intrinsic severity of their asthma and was better explained by ethnic, socioeconomic and sociocultural factors.
  • (5) On the other hand, the injection of minute quantities of endotoxin into PbAc(2)-sensitized rats invariably resulted in disseminated intravascular coagulation, apparently via a complete activation of the intrinsic pathway.
  • (6) Pathological changes may, thus, be initially confined to projecting and intrinsic neurons localized in cortical and subcortical olfactory structures; arguments are advanced which favor the view that excitotoxic phenomena could be mainly responsible for the overall degenerative picture.
  • (7) DL 071 IT, a new potent non-selective beta-adrenergic blocking drug with intrinsic sympathomimetic activity and weak membrane stabilizing activity, was evaluated alone and in comparison with oxprenolol, in six volunteers, at rest and during an exercise test.
