Investigate


Definition:

  • (v. t.) To follow up step by step by patient inquiry or observation; to trace or track mentally; to search into; to inquire and examine into with care and accuracy; to find out by careful inquisition; as, to investigate the causes of natural phenomena.
  • (v. i.) To pursue a course of investigation and study; to make investigation.

Example Sentences:

  • (2) We have investigated the effect of methimazole (MMI) on cell-mediated immunity and ascertained the mechanisms of immunosuppression produced by the drug.
  • (3) Lucy and Ed will combine coverage of hard and breaking news with a commitment to investigative journalism, which their track record so clearly demonstrates”.
  • (4) Clinical and roentgenographic criteria could not discriminate between patients with and without pneumonia, confirming the findings of previous investigations.
  • (5) The combined immediate and delayed responses to fleas in the dog are as observed by other investigators in man and guinea pigs.
  • (6) "As the investigation remains live and in order to preserve the integrity of that investigation, it would not be appropriate to offer further comment."
  • (7) The main clinical features pertaining to the concept of the "psycho-organic syndrome" (POS) were investigated in a sample of children who suffered from severe craniocerebral trauma.
  • (8) The ability of azelastine to influence antigen-induced contractile responses (Schultz-Dale phenomenon) in isolated tracheal segments of the guinea-pig was investigated and compared with selected antiallergic drugs and inhibitors of arachidonic acid metabolism.
  • (9) Electronmicroscopical investigations have revealed that, under normal conditions, a minor vesicular transfer of intravenously injected peroxidase occurs across the endothelium in segments of arterioles, capillaries and venules, especially in arterioles with a diameter about 15-30 mu.

  • (18) Among the groups investigated, the subjects with gastric tumors presented the greatest values.
  • (19) Typological and archaeological investigations indicate that the church building represents originally the hospital facility for the lay brothers of the monastery, which according to the chronicle of the monastery was built in the beginning of the 14th century.
  • (20) Therefore, we have developed a powerful new microcomputer-based system which permits detailed investigations and evaluation of 3-D and 4-D (dynamic 3-D) biomedical images.
