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 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.
[EX A]: yes

[EX Q]: Question: Do autism-associated gene Dlgap2 mutant mice demonstrate exacerbated aggressive behaviors and orbitofrontal cortex deficits?
Answer: Our findings clearly demonstrate that Dlgap2 plays a vital role in social behaviors and proper synaptic functions of the OFC. Moreover, these results may provide valuable insights into the neuropathology of autism.
[EX A]: yes

[EX Q]: Question: Does quantitative ultrasound identify patients with an inflammatory disease at risk of vertebral deformities?
Answer: Our findings imply that QUS measurements of the calcaneus in patients with an inflammatory condition, such as sarcoidosis and IBD, are likely of limited value to identify patients with a vertebral fracture.
[EX A]:
no
