Definition: 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.
Input: Question: Does ischemic post-conditioning attenuate renal ischemic reperfusion injury via down-regulation of toll-like receptor 4 in diabetic rats?
Answer: Taken together, our results suggest that proper IPO may have protective effect on the ischemic injury mediated by renal I/R, which might be associated with inhibition of TLR4 signaling pathway in diabetic rats.
Output:
yes
