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.

Input: Consider Input: Question: Does local adenovirus-mediated transfer of C-type natriuretic peptide suppress vascular remodeling in porcine coronary arteries in vivo?
Answer: Adenovirus-mediated CNP gene transfer with the IABC system may be a useful gene therapy to prevent restenosis after PTCA in vivo.

Output: yes

Input: Consider Input: Question: Is routine post-operative intensive care necessary for children with obstructive sleep apnea at high risk after adenotonsillectomy?
Answer: Our data confirm high rates of AE after AT for high risk patients, however, only 8% suffered a severe AE truly necessitating care in ICU. This outcome was very unlikely if an AE did not occur in PACU. We therefore conclude that routine post-operative ICU care for high risk children may be avoided if prolonged monitoring in the PACU is possible, with admission to ICU reserved for high-risk children with an early AE.

Output: no

Input: Consider Input: Question: Does progressive periodontal disease have a simultaneous incremental elevation of gingival crevicular fluid and serum CRP levels?
Answer: C-reactive protein levels in gingival crevicular fluid and serum increased proportionately with the severity of periodontal disease. They correlated positively with clinical parameters, including gingival index, probing pocket depth, and clinical attachment level. Thus, it can be considered as a periodontal inflammatory biomarker and deserves further consideration.
Output: yes
