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: Does pI3K and Bcl-2 inhibition prime glioblastoma cells to apoptosis through downregulation of Mcl-1 and Phospho-BAD?
Answer: Combination therapy with ABT-263 and GDC-0941 has novel therapeutic potential by specifically targeting aberrantly active, deregulated pathways in GBM, overcoming endogenous resistance to apoptosis.

SOLUTION: yes

PROBLEM: Question: Does mR Elastography demonstrate Increased Brain Stiffness in Normal Pressure Hydrocephalus?
Answer: This study demonstrates increased brain stiffness in patients with normal pressure hydrocephalus compared with age- and sex-matched healthy controls; these findings should motivate future studies investigating the use of MR elastography for this condition and the efficacy of shunt therapy.

SOLUTION: yes

PROBLEM: Question: Is gene and Protein Expression of Chemokine ( C-C-Motif ) Ligand 19 Upregulated in Unstable Carotid Atherosclerotic Plaques?
Answer: CCL19 is significantly overexpressed in patients with unstable carotid atherosclerotic plaques and may be a possible novel biomarker for identifying high-risk patients in whom more urgent intervention may be indicated.

SOLUTION:
yes
