[Q]: Question: 's it just the big kids : both high and low BMI impact bracing success for adolescent idiopathic scoliosis?
Answer: Based on our results, children on either end of the BMI spectrum are more likely to fail brace treatment for scoliosis than their mid-BMI counterparts. In high-BMI patients, this appears to be in large part attributable to an inadequacy of in-brace curve correction as well as to poorer brace compliance, while a low BMI appears to be an independent risk factor for brace failure.
[A]: no


[Q]: 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.
[A]: yes
