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 pINK1 trigger autocatalytic activation of Parkin to specify cell fate decisions?
Answer: Autocatalytic activation of Parkin bolsters its accumulation on mitochondria and apoptotic response to valinomycin. Our results suggest that PINK1-Parkin constitutes a damage-gated molecular switch that governs cellular-context-specific cell fate decisions in response to variable stress stimuli.

A: yes

Q: Question: Does insulin , unlike food intake , suppress ghrelin in human subjects?
Answer: Unlike food intake, the administration of insulin and glucose does not suppress ghrelin levels. These data suggest that the suppressive effect of food intake or oral glucose on serum ghrelin is unlikely mediated by the changes of plasma insulin and glucose observed after the ingestion.

A: no

Q: Question: Does four Weeks of Balance Training Affect Ankle Joint Stiffness in Subjects with Unilateral Chronic Ankle Instability?
Answer: Decreased inversion stiffness in the involved chronic unstable ankle was found that of uninvolved contralateral ankle. The 4-week balance training program intervention was ineffective in altering the mechanical characteristics of ankles with CAI.

A:
no
