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 [ Edaravone protect hearing from acute acoustic trauma in guinea pigs ]?
Answer: The level of ROS in cochlea were decreased significantly after intratympanic edaravone injection. The mechanism may due to its effective clearance of the ROS in cochlea.

A: yes

Q: Question: Does clinical examination assist in the detection of systemic relapse of testicular germ cell tumour?
Answer: We suggest that, for patients following a planned programme of appointments and investigations, physical examination rarely contributes to the detection of systemic relapse in the follow-up of testicular germ cell tumours. It may therefore be possible to reconfigure follow-up to focus on investigations and telephone contact. We estimate that this change might be appropriate for 40% of attendances and might be welcomed by patients, many of whom find follow-up burdensome. If such a change were considered, patient education would be essential to ensure continuing compliance with the follow-up protocol.

A: no

Q: Question: Is malonate as a ROS product associated with pyruvate carboxylase activity in acute myeloid leukaemia cells?
Answer: This study extends the interest in the PC activity in solid cancers to include leukaemias and further demonstrates the value of tracer-based NMR approaches in generating a more accurate picture of the flow of carbons and metabolites within the increasingly inappropriately named Krebs cycle. Moreover, our studies indicate that the PC activity in cancer cells can be exploited as an Achilles heel by using treatments, such as BaP, that elevate ROS production.

A:
yes
