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: Is increasing exposure to antibody-stimulating proteins and polysaccharides in vaccines associated with risk of autism?
Answer: In this study of MCO members, increasing exposure to antibody-stimulating proteins and polysaccharides in vaccines during the first 2 years of life was not related to the risk of developing an ASD.

Answer: no

Question: Question: Does the presence of functionally relevant toll-like receptor polymorphisms significantly correlate with development or outcome of sepsis?
Answer: None of the investigated SNPs clearly predicted outcome of sepsis-related multiorgan failure. TLR2-R753Q SNP may be a useful marker to identify patients with high risk to develop infections at ICU admission but should be validated in larger studies. Future SNP-arrays investigating predisposition for infection should include this SNP alone or in combination with other functionally relevant SNPs.

Answer:
no
