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.

Ex Input:
Question: Does combination of dehydroepiandrosterone and orthovanadate administration reduce intestinal leukocyte recruitment in models of experimental sepsis?
Answer: Our results indicate that DHEA is able to reduce intestinal leukocyte recruitment induced by experimental sepsis. Combination of DHEA with OV inhibits leukocyte adherence to intestinal endothelium, similar to what is achieved by the single administration of DHEA but with significantly improved FCD. These findings suggest a potential role for DHEA and OV in clinical sepsis.

Ex Output:
yes


Ex Input:
Question: Are decreased plasma levels of select very long chain ceramide species associated with the development of nephropathy in type 1 diabetes?
Answer: These studies demonstrate, prospectively, that decreased plasma levels of select ceramide species are associated with the development of macroalbuminuria in type 1 diabetes.

Ex Output:
yes


Ex Input:
Question: Are plasma serotonin and histamine levels in hemodialysis-related pruritus significantly influenced by 5-HT3 receptor blocker and antihistaminic therapy?
Answer: Histamine and serotonin are no major mediators of pruritus in hemodialysis patients. Elevated histamine levels are occassionally seen and may be due to the increased mast cell number found in a subgroup of hemodialysis patients. Our findings explain the only marginal relief of antihistamines and the controversial antipruritic effect of serotonin receptor antagonists in hemodialysis-related pruritus.

Ex Output:

no
