question:
Question: Does racemic ketamine abolish cerebrovascular autoregulation in the pig?
Answer: We conclude that autoregulation of CBF is not abolished during continuous ketamine infusion in normoventilated pigs and that previous divergent conclusions are unlikely to be associated with severe impairment of cerebrovascular autoregulation.
answer:
no


question:
Question: Is weight-adjusted resting energy expenditure constant in critically ill patients?
Answer: Predictive equations were not able to estimate measured REE adequately in all the patients. Adjusted REE decreased with increasing body mass index; thus, a body mass index group-specific adaptation for the estimation of energy needs should be applied.
answer:
no


question:
Question: Do random texts exhibit the real Zipf 's law-like rank distribution?
Answer: The good fit of random texts to real Zipf's law-like rank distributions has not yet been established. Therefore, we suggest that Zipf's law might in fact be a fundamental law in natural languages.
answer:

no
