question:
Question: Is routine post-operative intensive care necessary for children with obstructive sleep apnea at high risk after adenotonsillectomy?
Answer: Our data confirm high rates of AE after AT for high risk patients, however, only 8% suffered a severe AE truly necessitating care in ICU. This outcome was very unlikely if an AE did not occur in PACU. We therefore conclude that routine post-operative ICU care for high risk children may be avoided if prolonged monitoring in the PACU is possible, with admission to ICU reserved for high-risk children with an early AE.
answer:
no


question:
Question: Does constitutive secretion of Interleukin-4 dictate CD133+ side population cells to resist drug treatment and cell death?
Answer: Our data suggest that the autocrine secretion of IL-4 is a potential target for the development of novel anticancer drugs to prevent the CSCs-mediated therapy failure and tumorigenesis.
answer:
yes
