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 vasopressin raise cardiac enzymes following cardiac surgery : a randomized double-blind clinical trial?
Answer: Vasopressin infusion has been used to treat catecholamine-unresponsive shock. In this study, intraoperative vasopressin was used safely as a possible first-line drug for treating hypotension; however, it did not increase the levels of cardiac enzymes after cardiac surgery.
no

Question: Does fibroblast growth factor 8 regulate postnatal development of paraventricular nucleus neuroendocrine cells?
Answer: First, Fgf8 hypomorphy did not eliminate VP and CRH neurons in the mouse PVN, but rather disrupted the postnatal timing of neuropeptide expression onset in PVN neurons. Second, Fgf8 hypomorphy may, in part, be an explanation for affective disorders involving hyperactivity of the HPA axis, such as anxiety.
yes

Question: Does imbalance between pro and anti-oxidant mechanisms in perivascular adipose tissue aggravate long-term high-fat diet-derived endothelial dysfunction?
Answer: We suggest that the imbalance between pro-oxidant (NOX, superoxide anions, hydrogen peroxide) and anti-oxidant (eNOS, NO, ecSOD, GSSG) mechanisms in PVAT after long-term HFD might contribute to the aggravation of endothelial dysfunction.

yes
