Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

[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 ischemic preconditioning attenuate renal ischemia-reperfusion injury by inhibiting activation of IKKbeta and inflammatory response?
Answer: The evidence suggests that IKKbeta may play a role in renal I/R injury and give rise to the generation of NGAL. It appears that IPC may attenuate renal injury and the expression of NGAL following acute I/R injury. IKKbeta may offer a clinically accessible target for preventing renal injury following I/R.
[A]: yes


[Q]: Question: Does bacteriuria in patients with a continent ileal reservoir for urinary diversion regularly require antibiotic treatment?
Answer: The present results indicate that asymptomatic bacteriuria in patients with a continent ileal reservoir for urinary diversion is generally of no clinical importance and should not be treated with antibiotics. This conclusion is based on the observations that the bacterial strains growing in the reservoir changed spontaneously indicating colonization rather than infection. Raised titres of antibodies against E. coli correlated weakly with bacterial growth. The observed elevations in antibody titres were usually just above the normal upper limit.
[A]:
no
