Example Input: Question: Does neamine inhibit oral cancer progression by suppressing angiogenin-mediated angiogenesis and cancer cell proliferation?
Answer: Neamine effectively inhibits oral cancer progression through inhibition of tumor angiogenesis. Neamine also directly inhibits proliferation of certain types of oral cancer cells. Therefore, neamine has potential as a lead compound for oral cancer therapy.
Example Output: yes

Example Input: Question: Does stopcock lumen contamination reflect the full burden of bacterial intravenous tubing contamination : analysis using a novel injection port?
