Question: Question: Does developmental changes in spatial distribution of in vivo fluorescence and epidermal UV absorbance over Quercus petraea leave?
Answer: The spatial pattern of epidermal UV-screen over the area of oak leaves is related to leaf anatomy during development. In vivo spectroscopy and fluorescence imaging of the leaf surface showed the distribution of pigments within the leaf and hence can provide a tool to monitor optically the leaf development in nature.

Answer: yes

Question: Question: Does early primary repair of tetralogy of Fallot lead to increased postoperative resource utilization?
Answer: Extracardiac anomalies, prematurity, low birth weight, and nonelective surgical intervention are predictors of increased morbidity and increased hospital resource utilization and impose a significant cost burden to the care of these patients. Early primary repair of tetralogy of Fallot can be safely performed without any increase in morbidity or increased hospital resource utilization.

Answer: no

Question: Question: Does feeding an elemental diet vs a milk-based formula decrease intestinal mucosal growth in infant pigs?
Answer: We conclude that intestinal mucosal growth and villus morphology are similar in pigs fed ED and FORM, despite higher cell proliferation and protein synthesis rates and lower lactase activity with ED. This implies that elemental diets may be as trophic as polymeric formulas to simultaneously provide nutrition and a stimulus for intestinal growth during bowel rest.

Answer:
no
