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 a novel biomechanical device improve gait pattern in patient with chronic nonspecific low back pain?
Answer: Patients with NSLBP treated with the novel biomechanical device for 3 months increased walking speed through longer step length and eliminated asymmetrical differences.

SOLUTION: yes

PROBLEM: Question: Does overexpression of microRNA-155 suppress chemokine expression induced by Interleukin-13 in BEAS-2B human bronchial epithelial cells?
Answer: miR-155 specifically inhibits IL-13-induced expression of eosinophilic chemokines CCL11 and CCL26 in bronchial epithelial cells, even though the 3'-untranslated region of these genes do not contain a consensus binding site for miR-155.

SOLUTION: yes

PROBLEM: Question: Is s137 phosphorylation of profilin 1 an important signaling event in breast cancer progression?
Answer: Previous studies show that profilin could be executing a dual role in cancer by either suppressing or promoting tumorigenesis in a context dependent manner. In this study we demonstrate for the first time that phosphorylation of profilin 1 at serine 137 enhances oncogenic properties in breast cancer cells. Inhibitors targeting profilin 1 phosphorylation directly or indirectly through inhibition of kinases that phosphorylate profilin could be valuable therapeutic agents that can alter its activity and thereby control the progression of cancer.

SOLUTION:
yes
