PROBLEM: Question: Does racemic ketamine abolish cerebrovascular autoregulation in the pig?

SOLUTION: no

PROBLEM: Question: Is race a predictor of prostate cancer detection on repeat prostate biopsy?

Serum PSA, PSA velocity, HGPIN and ASAP were found to be significant predictors of subsequent prostate cancer detection.

SOLUTION: no
