The structural and genetic organization of the Escherichia coli O52 O antigen was studied. As identified by sugar and methylation analysis and nuclear magnetic resonance spectroscopy, the O antigen of E. coli O52 has a partially O-acetylated disaccharide repeating unit (O unit) containing D-fucofuranose and 6-deoxy-D-manno-heptopyranose, as well as a minor 6-deoxy-3-O-methylhexose (most likely,...

This result stands in contrast to the findings of previous studies for West German regions using cross-section regression techniques and is contrary to the time series findings for the United States.

Abstract Introduction Blood-borne cell-free nucleic acids are increasingly emerging as significant non-invasive adjuncts to current methods of disease status evaluation in cancer patients. In this study, we sought examine whether differences exist the plasma transcriptomic profile advanced melanoma patients with a high burden compared therapeutic response. Method Plasma circulating messenger ri...

Inspired by the theory of variety-expanding product innovation we derive a testable relationship of outsourcing on the growth rate of knowledge. We estimate this relationship with a firm-level dataset, which is a unique match of PATSTAT patent data and the Amadeus dataset. We find evidence that forward spillovers are stronger than backward spillovers, where forward spillovers are defined as spi...
