What's the difference between ejection and rejection?

Ejection


Definition:

  • (n.) The act of ejecting or casting out; discharge; expulsion; evacuation.
  • (n.) The act or process of discharging anything from the body, particularly the excretions.
  • (n.) The state of being ejected or cast out; dispossession; banishment.

  • (16) It was concluded that 1) late ejection was quantitatively important to LV pumping, 2) behavior during late ejection was inconsistent with E(t)-R, and 3) ad hoc modification of E(t)-R models was not likely to yield LV pumping models that could satisfactorily reproduce instantaneous P(t) and Q(t) behavior over the entire ejection period.
  • (17) The results showed that the shortening fractions and ejection fractions were significantly depressed in the experimental embryos.
  • (18) Global left ventricular ejection fraction (LVEF) was obtained by radionuclide angiography and analyzed with an automatic detection program.
  • (19) Thus, patients are likely to live longer after CABG if they have left main disease; three-vessel disease with left ventricular dysfunction (ejection fraction less than 50%), class III or IV angina, provocable ischemia, or disease in the proximal left anterior descending coronary artery; two-vessel disease with proximal left anterior descending artery involvement; and two-vessel disease with class III or IV angina as well as either severe left ventricular dysfunction alone or moderate left ventricular dysfunction together with at least one proximal lesion.
  • (20) The maintenance of adequate blood circulation requires a sufficient ventricular contractility; in addition, to eject blood, the ventricles must first receive a sufficient volume, requiring a low diastolic stiffness.

Rejection


Definition:

  • (n.) Act of rejecting, or state of being rejected.

Example Sentences:

  • (1) Acceptance of less than ideal donors is ill-advised even though rejection of such donors conflicts with the current shortage of organs.

  • (4) These results suggest that prevention of xenograft rejection using PAF-antagonist in association with other methods should be further investigated.
  • (5) Clinical diagnosis of rejection was made independently of immunological results.
  • (6) GlaxoSmithKline was unusually critical of the decision by Nice, the National Institute for Health and Clinical Excellence, and also the Scottish Medicines Consortium, to reject its drug belimumab (brand name Benlysta) in final draft guidance.
  • (7) Maintenance therapy was always steroid-free to start with (cyclosporin+azathioprine) but in almost one half of our oldest survivors, it failed to avoid rejection and we had to add low-dose oral steroids for at least several months.
