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 the bradykinin B1 receptor antagonist BI113823 reverse inflammatory hyperalgesia by desensitization of peripheral and spinal neurons?
Answer: The selective bradykinin B1 receptor antagonist BI113823 reduces CFA-induced mechanical hyperalgesia which is mediated via antagonism of peripheral as well as spinal bradykinin B1 receptors. The selective modulation of CFA-sensitized spinal NS neurons by BI113823 could be a promising property for the treatment of inflammatory pain.

Ex Output:
yes

Ex Input:
Question: Is the high-dose sequential ( Milan ) chemotherapy/PBSC transplantation regimen for patients with lymphoma cardiotoxic?
Answer: The HDS chemotherapy regimen produced no significant sign of cardiotoxicity up to one year after transplantation in patients with normal baseline cardiac function and no history of cardiac disease, pretreated with up to 550 mg/m2 of doxorubicin.

Ex Output:
no

Ex Input:
Question: Do plastic wound protectors affect wound infection rates following laparoscopic-assisted colectomy?
Answer: The wound protector, although useful for mechanical retraction of small wounds, does not significantly diminish the rate of wound infection at the bowel resection/anastomotic site. Patients undergoing elective resection for inflammatory processes have higher infection rates than patients undergoing laparoscopic-assisted colectomy for polyps or cancer.

Ex Output:
no
