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.

[EX Q]: Question: Does in vivo imaging of antileukemic drug asparaginase reveal a rapid macrophage mediated clearance from the bone marrow?
Answer: We show that asparaginase is rapidly cleared from the serum by liver, spleen and bone marrow-resident phagocytic cells. As a consequence of this efficient uptake and protease mediated degradation, particularly bone marrow resident macrophages may provide a protective niche to leukemic cells.
[EX A]: yes

[EX Q]: Question: Does protamine affect the formation of cGMP or cAMP in pig vascular smooth muscle cells in response to vasodilators?
Answer: These experiments show that protamine does not alter the responses of the intracellular second messengers, cGMP and cAMP, to the vasodilators sodium nitroprusside, atrial natriuretic peptide, isoproterenol, and forskolin. These results do not support the hypothesis that protamine sensitizes vascular smooth muscle cells to the endothelium-derived relaxing factor, nitric oxide.
[EX A]: no

[EX Q]: Question: Is transthoracic ultrasonography an alternative to subxyphoid ultrasonography for the diagnosis of hemopericardium in penetrating precordial trauma?
Answer: Surgeon-performed ultrasonography has become the diagnostic test of choice for patients suspected of having hemopericardium and cardiac tamponade. Transthoracic ultrasonography is an excellent alternative for those patients where a subxyphoid or subcostal view to visualize the pericardial sac and heart cannot be obtained owing to local or anatomical factors.
[EX A]:
yes
