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: Does insulin , unlike food intake , suppress ghrelin in human subjects?
Answer: Unlike food intake, the administration of insulin and glucose does not suppress ghrelin levels. These data suggest that the suppressive effect of food intake or oral glucose on serum ghrelin is unlikely mediated by the changes of plasma insulin and glucose observed after the ingestion.
no

Question: Does nitric acid passivation affect in vitro biocompatibility of titanium?
Answer: Although the protocol for passivation used here could interfere with the pattern of ions released from Ti-6Al-4V and cpTi surfaces, the present study did not show any effect of this surface treatment on in vitro biocompatibility of Ti as evaluated by osteoblast attachment, proliferation, and differentiation.
no

Question: Does peptide XIB13 reduce capillary leak in a rodent burn model?
Answer: Xib13 improved angiogenesis, reduced edema formation and showed no side effects on other physiological parameters. Since edema formation is a serious parameter for burn conversion and is associated with survival it could provide a new treatment option for patients with burn injuries.
yes
