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 leukocyte concentration and composition in platelet-rich plasma ( PRP ) influence the growth factor and protease concentrations?
Answer: These findings demonstrate that leukocytes strongly influence the quality of PRPs. Therefore, modifying the PRP preparation method according to the pathology is essential to achieve better clinical results with PRP therapy.
[EX A]: yes

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

[EX Q]: Question: Does unilateral Hypothalamus Inactivation prevent PTZ Kindling Development through Hippocampal Orexin Receptor 1 Modulation?
Answer: It is concluded that LHA inactivation prevented kindling development probably through orexin receptor antagonism. CSF orexin probably acts as an inhibitory step on convulsive intensity through another unknown process.
[EX A]:
yes
