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: Does acute ethanol always affect delay discounting in rats selected to prefer or avoid ethanol?
Answer: Our data indicate that in these lines of animals, alcohol preference or avoidance has no impact on delay discounting following acute ethanol exposure. It is possible that other genetic models or lines may be differentially affected by alcohol and exhibit qualitatively and quantitatively different responses in delay discounting tasks.
answer:
no


question:
Question: Are bone marrow-derived keratinocytes detected in normal skin and only rarely detected in wounded skin in two different murine models?
Answer: These results suggest that BMDCs do not significantly contribute to steady-state epidermal homeostasis and are not required or responsible for providing keratinocyte stem cells and keratinocyte repopulation following skin injury.
answer:

no
