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: Do xenon and nitrous oxide depress cardiac function in an isolated rat heart model?
Answer: Our data suggest that cardiac contractility was decreased by the effects of reduced O2 delivery, but both Xe and N2O did not cause further cardiac depressant effects compared to N2 in this experimental model.

Output: no


Input: Consider Input: Question: Are mutational status of KIT and PDGFRA and expression of PDGFRA associated with prognosis after curative resection of primary gastrointestinal stromal tumors ( GISTs )?
Answer: Our data do not support the notion that expression of PDGFRA or mutations in KIT or PDGFRA are independent prognostic factors after curative resection of primary GIST.

Output: no


Input: Consider Input: Question: Is apolipoprotein D deficiency associated to high bone turnover , low bone mass and impaired osteoblastic function in aged female mice?
Answer: Our results indicate that ApoD influences bone metabolism in mice in a gender-specific manner, potentially through an auto-/paracrine pathway.


Output: yes
