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 peroxiredoxin 1 promote pancreatic cancer cell invasion by modulating p38 MAPK activity?
Answer: Prdx1 associates with the formation of membrane protrusions through modulation of the activity of p38 MAPK, which in turn promotes PDAC cell invasion.
[EX A]: yes

[EX Q]: Question: Does histologic evaluation of in vivo femtosecond laser-generated capsulotomies reveal a potential cause for radial capsular tears?
Answer: Femtosecond laser can perform a capsulotomy with high reliability. In comparison to a highly experienced cataract surgeon, the achieved results in size are similar. In terms of circularity, the femtosecond laser was superior the manual procedure. Better refractive outcomes based on a 360-degree optic overlap seem to be possible, especially for less experienced surgeons.
[EX A]: yes

[EX Q]: Question: Does plateletpheresis cause long-standing platelet-derived growth factor release into the donor blood?
Answer: Only a slight and rapidly reversible increase in soluble PDGF-AB was found during plateletpheresis and no increase in soluble TGF-beta1 and beta-TG was found. This change should not be harmful to the donor.
[EX A]:
no
