  • (12) This was overcome by using a continuous subcutaneous infusion pump which also enabled the effective daily dosage to be reduced and thereby adverse reactions to be avoided.
  • (13) These results suggest that CPZ interacts with smg p21B, smg GDS, or both, and thereby inhibits the smg GDS action, and that CPZ also interacts with the acidic phospholipids and thereby counteracts their inhibitory effect on the smg GDS action.

  • (15) In recent years, apart from these well known risks, the immuno-suppressive effect of blood transfusions has been observed and thereby the possible adverse influence on the prognosis in cases of malignant disease.
  • (16) From this information, it would appear that it is possible that the mechanism for the prolonged effect of acupuncture in treating chronic pain is that the repeated activation of the physiological systems by which acupuncture inhibits pain, by the repeated acupuncture treatments, trains the body to continue this activity and thereby maintains the pain relief for a period of time after the last treatment.
  • (17) Among these are DNA exo- and endonucleases and DNA glycosylases which remove oxidatively damaged portions of the DNA molecule, thereby initiating excision-repair.
  • (18) Taken together, these findings indicate that IGFs can stabilize neuronal calcium homeostasis and thereby protect against hypoglycemic damage.
  • (19) Drugs known to improve memory, including physostigmine, pramiracetam and the muscarinic agonists, oxotremorine and RS 86, selectively induced analgesia in rats subjected to test before the shock plus the shock, thereby supporting a hypothesis of avoidance learning.
  • (20) The increased volume of flowing blood and increased stroke volume in athletes probably allows for a reduction in flow velocity and thereby a reduction in kinetic energy.

Therein


Definition:

  • (adv.) In that or this place, time, or thing; in that particular or respect.

Example Sentences:
