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 δNp63α enhance the oncogenic phenotype of osteosarcoma cells by inducing the expression of GLI2?
Answer: Here, we report that GLI2 is the novel target gene of ΔNp63α and that ΔNp63α-GLI2 crosstalk in osteosarcoma cells is a necessary event in osteosarcoma progression. Defining the exact mechanisms involved in this interaction that mediate the pathogenesis of osteosarcoma promises to identify targets for drug therapy.

Ex Output:
yes


Ex Input:
Question: Does adjuvant Stereotactic Radiosurgery reduce Need for Retreatments in Patients with Meningioma Residuals?
Answer: aSRS of meningioma residuals had a positive effect on tumor control and should be considered in patients with meningioma residuals.

Ex Output:
yes


Ex Input:
Question: Does transcriptome Analysis reveal Regulation of Gene Expression for Lipid Catabolism in Young Broilers by Butyrate Glycerides?
Answer: Our results demonstrate that BG reduces body fat deposition via regulation of gene expression, which is involved in the biological events relating to the reduction of synthesis, storage, transportation and secretion, and improvement of oxidation of lipids and fatty acids.

Ex Output:

yes
