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: Is lipoprotein internalisation induced by oncogenic AMPK activation essential to maintain glioblastoma cell growth?
Answer: Our findings demonstrate that AMPK plays a crucial role in glioblastoma cell growth and suggest that blocking lipoprotein receptors could potentially be used as a plausible therapeutic approach for these and other type of tumours with high levels of AMPK.

Output: yes


Input: Consider Input: Question: Does the extent of lymphadenectomy for pTXNO prostate cancer affect prostate cancer outcome in the prostate specific antigen era?
Answer: The extent of lymphadenectomy does not appear to affect prostate cancer outcome in lymph node negative cases. This includes patients with high preoperative PSA, high pathological grade and extracapsular disease. These results suggest that under staging is not present in apparently node negative cases with limited lymphadenectomy and, even if present, its impact on outcome is likely to be negligible.

Output: no


Input: Consider Input: Question: Are higher heart rate increments on head-up tilt in control subjects associated with autonomic dysfunction?
Answer: These results argue against a reduction in autonomic function underlying the higher heart rate increments seen on HUT in younger individuals.


Output: no
