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.

[EX 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.
[EX A]: yes

[EX Q]: Question: Is radiological review of specimen radiographs after breast localisation biopsy always necessary?
Answer: This study shows that a suitably trained or experienced surgeon can assess specimen radiographs effectively without the need for intraoperative radiological input although complete histological resection is not guaranteed despite specimen radiographs demonstrating clear margins.
[EX A]: no

[EX Q]: Question: Does autocrine secretion of 15d-PGJ2 mediate simvastatin-induced apoptotic burst in human metastatic melanoma cells?
Answer: We characterized simvastatin-induced activation of the 15d-PGJ2 /FABP5 signalling cascades, which triggered an apoptotic burst in melanoma cells but did not affect primary human melanocytes. These data support the rationale for the pharmacological targeting of 15d-PGJ2 in metastatic melanoma.
[EX A]:
yes
