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.

Example Input: Question: Does toll-like receptor 4 signaling contribute to Paclitaxel-induced peripheral neuropathy?
Answer: The toll-like receptor TLR4 and MyD88 signaling pathway could be a new potential therapeutic target in paclitaxel-induced painful neuropathy.
Example Output: yes

Example Input: Question: Is differential regulation of gene products in newly synthesized Brassica napus allotetraploids related to protein function nor subcellular localization?
Answer: Protein identification showed that functionally related polypeptides (isoforms and complex subunits) could be differentially regulated in synthetic B. napus in comparison to its diploid progenitors while such proteins are usually expected to display co-regulation. The genetic redundancy within an allopolyploid could explain why functionally related proteins could display imbalanced levels of expression. No functional category, no metabolic pathway and no subcellular localization was found to be over- or under-represented within non-additive polypeptides, suggesting that the differential regulation of gene products was not related to functional properties of the proteins. Thus, at the protein level, there is no evidence for the "genomic shock" expected in neo-polyploids and the overall topology of protein networks and metabolic pathways is conserved in synthetic allotetraploids of B. napus in comparison to its diploid progenitors B. rapa and B. oleracea.
Example Output: no

Example Input: Question: Is transfusion of packed red blood cells associated with improved central venous oxygen saturation or organ function in patients with septic shock?
Answer: In this study, the transfusion of PRBC was not associated with improved cellular oxygenation, as demonstrated by a lack of improved achievement of ScvO(2)>70%. Also, the transfusion of PRBC was not associated with improved organ function or improved achievement of the other goals of EGDT. Further studies are needed to determine the impact of transfusion of PRBC within the context of early resuscitation of patients with septic shock.
Example Output:
no
