Ex Input:
Question: Does presence of the full-length KIR2DS4 gene reduce the chance of rheumatoid arthritis patients to respond to methotrexate treatment?
Answer: Our results suggest that the response of RA patients with medium ESR values to MTX treatment may be dependent on the full-length KIR2DS4 gene.

Ex Output:
yes

Ex Input:
Question: Are hypometric anticipatory postural adjustments in dystonia affected by deep brain stimulation of globus pallidus internus?
Answer: Observations that APAs are impaired in dystonia and are at the same time not affected by the stimulation current are compatible with the assumption that APAs and dystonic symptoms may rely on distinct networks, possibly within the same cortical and basal ganglia structures. With no effect of stimulation on APAs it is unlikely that this would be a mechanism of impaired balance in the patients after the surgery.

Ex Output:
no
