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: 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.

Answer: no


Question: Question: Is s100A8/A9 involved in host defense against murine urinary tract infection?
Answer: We show that despite high S100A8/A9 expression in bladder and kidney tissue upon UTI, S100A8/A9 does not contribute to an effective host response against E. Coli in the urinary tract system.

Answer: no


Question: Question: Does ileoanal-pouch reconstruction impair sphincter function or quality of life?
Answer: Proctocolectomy combined with IPAA neither deteriorates anorectal function nor quality of life compared to conservatively treated controls. These data support that prophylactic proctocolectomy in patients who are at high risk for the development of colorectal cancer can be performed at an early stage of the disease.

Answer:
no
