TASK DEFINITION: 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.
PROBLEM: Question: Is an Ile93Met substitution in the UCH-L1 gene a disease-causing mutation for idiopathic Parkinson 's disease?
Answer: Our study suggested that Ile93Met of UCH-L1 gene did not influence risk of IPD.

SOLUTION: no

PROBLEM: Question: Is a high body mass index in esophageal cancer patients associated with adverse outcomes following esophagectomy?
Answer: A high BMI is not associated with increased overall morbidity following esophagectomy; moreover, it is associated with decreased incidence of chylothorax. The better overall survival in patients with high BMI compared with those with low BMI might be due to a relatively low pathological stage. A high BMI should therefore not be a relative contraindication for esophagectomy.

SOLUTION: no

PROBLEM: Question: Is re-creation of sinuses important for sparing the aortic valve : a finite element study?
Answer: Valve-sparing techniques that allow the potential for sinus space formation (tailored, pseudosinus) result in simulated leaflet stresses that are closer to normal than the cylindrical technique. Normalized leaflet stresses in the clinical setting may result in improved longevity of the spared valve.

SOLUTION:
yes
