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: Are findings in the distal colorectum associated with proximal advanced serrated lesions?
Answer: The findings at flexible sigmoidoscopy that traditionally serve as indications for colonoscopy (conventional adenomas) are likely to be ineffective for detection of proximal ASL. This finding, plus the observation that most patients with proximal ASL have no distal polyps, favors screening colonoscopy over sigmoidoscopy, especially in the elderly. The observation that non-advanced distal SSA/Ps are associated with any proximal SSA/P warrants further study.

Output: no


Input: Consider Input: Question: Does the usage of overtube have a favorable effect on endoscopic submucosal dissection?
Answer: We conclude that using an overtube during an upper gastrointestinal ESD decreases the need for suction, favors the speed of dissection, and eases the comfort of the procedure.

Output: yes


Input: Consider Input: Question: Does microRNA367 negatively regulate the inflammatory response of microglia by targeting IRAK4 in intracerebral hemorrhage?
Answer: In conclusion, our study demonstrates that miR-367/IRAK4 pathway plays an important role in microglial activation and neuroinflammation in ICH. Our finding also suggests that miR-367 might represent a potential therapeutic target for ICH.


Output: yes
