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 remote ischemic preconditioning affect the incidence of acute kidney injury after elective abdominal aortic aneurysm repair?
Answer: RIPC did not reduce the risk of postoperative renal failure or myocardial injury in patients undergoing open AAA repair. The authors' results do not support the introduction of this technique to routine clinical practice.
[A]: no

[Q]: Question: Do workers of a drywood termite work?
Answer: Thus, in contrast to general perception where termite workers are considered equivalent to workers in Hymenoptera, the 'large immatures' of C. secundus did not behave as workers that help in raising younger siblings. This apparently is not necessary as the colony lives inside its food. These results, which are likely to be typical for wood-dwelling termites, open the possibility that large complex group living can evolve without altruistic helping and that costly altruistic helping by workers in termites evolved only as a second step.
[A]: no

[Q]: Question: Does endothelial -Catenin Signaling be Required for Maintaining Adult Blood-Brain Barrier Integrity and Central Nervous System Homeostasis?
Answer: These results demonstrate the prerequisite role of endothelial -catenin in maintaining the integrity of adult BBB. The results suggest that BBB dysfunction secondary to defective -catenin transcription activity is a key pathogenic factor in hemorrhagic stroke, seizure activity, and central nervous system inflammation.
[A]:
yes
