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 the Drosophila Chmp1 protein determine wing cell fate through regulation of epidermal growth factor receptor signaling?
Answer: Drosophila Chmp1 negatively regulates DER signaling, likely through its role in MVB formation. Loss of Chmp1 activity in the Drosophila wing induces a cell fate change from intervein to vein that should provide a useful tool for future studies of ESCRT protein activity.
[A]: yes


[Q]: Question: Does intracanal delivery of Resolvin E1 control inflammation in necrotic immature rat teeth?
Answer: RvE1 and TAP had a positive impact on reducing inflammation and promoting root formation. RvE1 was more effective in reducing inflammation at earlier stages. RvE1 has potential to be used as root canal dressing to control inflammation in endodontically compromised teeth before complete root formation. Stability of RvE1 within the root canal and its delivery are issues to be addressed before its clinical use.
[A]: yes


[Q]: Question: Does gabapentin reduce post-thoracotomy shoulder pain : a randomized , double-blind placebo-controlled study?
Answer: Pre-emptively administered gabapentin, 1200 mg, does not reduce the incidence, or the severity, of post-thoracotomy shoulder pain in patients receiving thoracic epidural analgesia.
[A]:
no
