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: Does developmental changes in spatial distribution of in vivo fluorescence and epidermal UV absorbance over Quercus petraea leave?
Answer: The spatial pattern of epidermal UV-screen over the area of oak leaves is related to leaf anatomy during development. In vivo spectroscopy and fluorescence imaging of the leaf surface showed the distribution of pigments within the leaf and hence can provide a tool to monitor optically the leaf development in nature.
[A]: yes


[Q]: Question: Does sublingual application of liquid nitrendipine result in critical hypotension in healthy volunteers under phosphodiesterase-5 inhibition?
Answer: Sublingual nitrendipine seems to be safe for self-treatment of an anginal attack in patients with stable coronary artery disease, who have taken a phosphodiesterase-5 inhibitor. However, our findings on hemodynamic changes in apparently healthy volunteers have to be confirmed in patients with coronary artery disease.
[A]:
no
