Active


Definition:

  • (a.) Having the power or quality of acting; causing change; communicating action or motion; acting; -- opposed to passive, that receives; as, certain active principles; the powers of the mind.
  • (a.) Quick in physical movement; of an agile and vigorous body; nimble; as, an active child or animal.
  • (a.) In action; actually proceeding; working; in force; -- opposed to quiescent, dormant, or extinct; as, active laws; active hostilities; an active volcano.
  • (a.) Given to action; constantly engaged in action; energetic; diligent; busy; -- opposed to dull, sluggish, indolent, or inert; as, an active man of business; active mind; active zeal.
  • (a.) Requiring or implying action or exertion; -- opposed to sedentary or to tranquil; as, active employment or service; active scenes.
  • (a.) Given to action rather than contemplation; practical; operative; -- opposed to speculative or theoretical; as, an active rather than a speculative statesman.
  • (a.) Brisk; lively; as, an active demand for corn.
  • (a.) Implying or producing rapid action; as, an active disease; an active remedy.
  • (a.) Applied to a form of the verb; -- opposed to passive. See Active voice, under Voice.
  • (a.) Applied to verbs which assert that the subject acts upon or affects something else; transitive.
  • (a.) Applied to all verbs that express action as distinct from mere existence or state.

Example Sentences:

  • (14) One hour after direct mechanical cardiomassage (DMCM) a moderately pronounced edema of the intercellular spaces in the basal compartment of the seminiferous epithelium, normal content of lactate and succinate dehydrogenases, and a certain decrease in the activity of glucose-6-phosphate dehydrogenases and NAD- and NADP-diaphorases were noted.
  • (15) We conclude that first-transit and blood-pool techniques are equally accurate methods for determining EF when the time-activity method of analysis is employed.
  • (16) This difference was not due to ATPase activity in the assay.

  • (20) Together these results suggest that IVC may operate as a selective activator of calpain both in the cytosol and at the membrane level; in the latter case in synergism with the activation induced by association of the proteinase to the cell membrane.
