Question: Question: Is low caregiver health literacy associated with higher pediatric emergency department use and nonurgent visits?
Answer: Over half of caregivers presenting with their children to the ED have low health literacy. Low caregiver health literacy is an independent predictor of higher ED use and use of the ED for nonurgent conditions. In children without a chronic illness, low health literate caregivers had more than 3 times greater odds of presenting for a nonurgent condition than those with adequate health literacy.

Answer: yes

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

Question: Question: Are well differentiation and intact Smad4 expression specific features of groove pancreatic ductal adenocarcinomas?
Answer: These results suggest that GPDACs arise from small branch pancreatic ducts around accessory pancreatic duct penetrating the groove and duodenum and are distinguishable from DACs. Molecular immunohistochemistry suggests the accumulation of genetic abnormalities during tumor progression is slow in comparison with cPDACs. Thus, the site of PDAC occurrence, such as the border or inner area of the pancreas head, may determine genetic progressivity.

Answer:
yes
