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.

Question: Are common genetic variants related to vitamin D status associated with esophageal squamous cell carcinoma risk in China?
Answer: Our results suggested that common genetic variants related to vitamin D levels are not associated with risk of ESCC in this Chinese population.
no

Question: Are biphasic redistribution of muscarinic receptor and the altered receptor phosphorylation and gene transcription underlying mechanisms in the rat heart during sepsis?
Answer: The m2AChR in the rat heart was externalized from light vesicles to sarcolemma (overexpression) during early sepsis but internalized from surface membranes to intracellular sites (underexpression) during late sepsis. Furthermore, changes in the receptor phosphorylation and gene transcription are responsible for the biphasic redistribution and the altered expression of m2AChR in the rat heart during the progression of sepsis.
yes

Question: Do experimental evaluation of sand fly collection and storage methods for the isolation and molecular detection of Phlebotomus-borne viruses?
Answer: While the collection and storage methods investigated had not much impact on the ability to detect viral RNA by molecular methods, they affected the capacity to recover viable viruses. Consequently, sand fly collection and handling procedures should be established in advance depending on the goal of the surveillance studies.

yes
