[Q]: 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.
[A]: no


[Q]: Question: Does ataxia Severity correlate with White Matter Degeneration in Spinocerebellar Ataxia Type 7?
Answer: These results suggest a significant contribution of local cerebellar and cerebellar-midbrain connections to ataxic impairment in spinocerebellar ataxia type 7. The results also suggest an involvement of cortical WM abnormalities including tracts within the occipital and frontal cortices. These findings contribute to a more comprehensive view of the clinical impact of the white matter degeneration in spinocerebellar ataxia type 7.
[A]: yes


[Q]: Question: Does acid reflux into the oesophagus influence exercise-induced airway narrowing in bronchial asthma?
Answer: The results indicate that acid in the oesophagus, or its short-term inhibition by proton pump inhibitors, has no influence on exercise-induced bronchoconstriction.
[A]:
no
