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.

Input: Consider Input: Question: Does bacteriuria in patients with a continent ileal reservoir for urinary diversion regularly require antibiotic treatment?
Answer: The present results indicate that asymptomatic bacteriuria in patients with a continent ileal reservoir for urinary diversion is generally of no clinical importance and should not be treated with antibiotics. This conclusion is based on the observations that the bacterial strains growing in the reservoir changed spontaneously indicating colonization rather than infection. Raised titres of antibodies against E. coli correlated weakly with bacterial growth. The observed elevations in antibody titres were usually just above the normal upper limit.

Output: no


Input: Consider Input: Question: Does transient ischemia limit subsequent ischemic regional dysfunction in humans : a transesophageal echocardiographic study during minimally invasive coronary artery bypass surgery?
Answer: Ischemic dysfunction was precipitated by the 5-min LAD occlusion, as shown by the increase in LVWMS and pulmonary artery pressure. However, a 5-min coronary occlusion and the resulting ischemia do not alter regional left ventricular systolic function during subsequent ischemia in humans.

Output: no


Input: Consider Input: Question: Does pretreatment with calcitonin gene-related peptide attenuate hepatic ischemia/reperfusion injury in rats?
Answer: CGRP ameliorated liver I/R injury due to reactive oxygen species and apoptosis.


Output: yes
