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 indoleamine 2,3-dioxygenase inhibition alter the non-coding RNA transcriptome following renal ischemia-reperfusion injury?
Answer: These results suggest a biologic role for non-coding, IDO-dependent genes in regulating the early response to IRI.
[EX A]: yes

[EX Q]: Question: Does the rtPA increase MMP-9 activity in serum during ischaemic stroke?
Answer: Thrombolysis applied for IS treatment increases MMP-9 activity in serum, however, rtPA does not facilitate the conversion of pro-MMP-9 into the active form. Our results also suggest the involvement of MMP-3 to the biochemical processes occurring during acute phase of IS.
[EX A]: yes

[EX Q]: Question: Are shorter hospital stay associated with fastrack postoperative care pathways and laparoscopic intestinal resection associated with increased physical activity?
Answer: Although CA is an easily standardized method of evaluating physical activity after major abdominal surgery, no difference can be demonstrated between activity levels in patients managed by differing care pathways. Reductions in stay may be associated with factors other than a change in the level of physical activity after surgery.
[EX A]:
no
