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.

[Q]: Question: Is the G-308A variant of the Tumor Necrosis Factor-alpha ( TNF-alpha ) gene associated with obesity , insulin resistance and body fat distribution?
Answer: Our study did not detect any significant association of the G-308A TNFalpha polymorphism with obesity or with its clinical and metabolic abnormalities in this population. Our data suggests that, in our population, the G-308A TNFalpha polymorphism is unlikely to play a major role in the pathogenesis of these conditions.
[A]: no


[Q]: Question: Are wedding rings a significant source of bacterial contamination following surgical scrubbing?
Answer: This preliminary study would suggest that a traditional band wedding ring is not a source of a bacterial load following a standard surgical scrub procedure and, as such, there is no requirement for their removal pre-operatively.
[A]: no


[Q]: Question: Does pPAR-alpha dependent regulation of vanin-1 mediate hepatic lipid metabolism?
Answer: We show that hepatic vanin-1 is under extremely sensitive regulation by PPARα and that plasma vanin activity could serve as a readout of changes in PPARα activity in human subjects. In addition, our data propose a role for vanin-1 in regulation of hepatic TG levels during fasting.
[A]:
yes
