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.

Example Input: Question: Do the synergistic effects of shear stress and cyclic hydrostatic pressure modulate chondrogenic induction of human mesenchymal stem cells?
Answer: Differentiation of ASCs was shown by a modest increase in gene expression profiles. In general, BSCs expressed higher levels of chondrogenic gene expression than ASCs after 3 weeks. A greater effect on Col II and SOX9 mRNA expression was observed when combined loadings were applied. Results may be applied in determining the proper loading sequence for obtaining functional target cells in cartilage engineering applications.
Example Output: yes

Example Input: Question: Does switching types of drug-eluting stents prevent repeated in-stent restenosis in patients with coronary drug-eluting stent restenosis?
Answer: A strategy involving repeated DES implantation was superior to POBA for preventing recurrent restenosis. Treatment with a different type or generation of DES does not appear to reduce the incidence of TLR. Moreover, we identified certain useful factors for facilitating appropriate and early triage in the patients with repeated DES ISR.
Example Output: no

Example Input: Question: Is inhibition of B-NHEJ in plateau-phase cells a direct consequence of suppressed growth factor signaling?
Answer: The results document a rapid and fully reversible adaptation of B-NHEJ to growth activity and point to factors beyond EGFR in its regulation. They show notable differences in the regulation of error-prone DSB repair pathways between proliferating and non proliferating cells that may present new treatment design opportunities in radiation therapy.
Example Output:
no
