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.

Question: Does apelin-13 protect the heart against ischemia-reperfusion injury through the RISK-GSK-3-mPTP pathway?
Answer: The protective mechanism of apelin-13 might be that inactivation of GSK-3 could inhibit the opening of mPTP by activating PI3K/Akt and ERK1/2 involved in the reperfusion injury salvage kinase (RISK) pathway.
yes

Question: Does interleukin-6 stimulate rat myometrial contractions in an in vitro model?
Answer: IL-6 in the presence or absence of membranes, over a four log fold dose range, did not stimulate uterine contractions.
no

Question: Does a specific binding site for the prorenin propart peptide Arg10-Arg20 occur on human endothelial cells?
Answer: The binding of the human prorenin peptide RIFLKRMPSIR to HUVEC proteins is not specific for amino acid sequence and probably involves a general peptide/protein uptake mechanism. We could not detect a specific prorenin propart binding site in these cells.
no
