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 nitric oxide-dependent renal vasodilatation altered in rat with rHuEpo-induced hypertension?
Answer: The analysis of our results seems to indicate that the endogenous NO system activity was enhanced in rHuEpo-induced hypertension in rats with normal renal function and a resistance to NO was not developed in renal circulation. Further studies seem to be necessary to better clarify the exact mechanisms underlying the development of rHuEpo-induced hypertension.

Q: Question: Is detection of micrometastatic prostate cancer cells in the lymph nodes by reverse transcriptase polymerase chain reaction predictive of biochemical recurrence in pathological stage T2 prostate cancer?
Answer: Nested RT-PCR of the lymph nodes may be a useful pretreatment prognostic test for patients undergoing radical prostatectomy. Further research is necessary using a much larger number of patients with a longer followup.

A:
yes
