Ex Input:
Question: Does preinjury beta blocker usage affect the heart rate response to initial trauma resuscitation?
Answer: Preinjury beta blockade is associated with a slower presenting heart rate, more bradycardia, less tachycardia, but no difference in mortality or ability to achieve a normal heart rate with resuscitation.

Ex Output:
no


Ex Input:
Question: Does local adenovirus-mediated transfer of C-type natriuretic peptide suppress vascular remodeling in porcine coronary arteries in vivo?
Answer: Adenovirus-mediated CNP gene transfer with the IABC system may be a useful gene therapy to prevent restenosis after PTCA in vivo.

Ex Output:
yes


Ex Input:
Question: Does deep sedation with dexmedetomidine in a porcine model compromise the viability of free microvascular flap as depicted by microdialysis and tissue oxygen tension?
Answer: Our data suggest that dexmedetomidine, even if used for deep sedation, does not have deleterious effects on local perfusion or tissue metabolism in denervated musculocutaneous flaps.

Ex Output:

no
