Serotypes O2, O5, and O16 of Pseudomonas aeruginosa are chemically related, and the O antigens of their lipopolysaccharides share a similar trisaccharide repeat backbone structure. Serotype-specific monoclonal antibodies (MAbs) MF71-3, MF15-4, and MF47-4 against the O2, O5, and O16 serotypes, respectively, were isolated. MAb 18-19, which is cross-reactive with all strains of this chemically rel...
A straightforward synthesis of the tetrasaccharide repeating unit of the O-antigen of Escherichia coli O16 has been achieved following a sequential glycosylation strategy. A minimum number of steps was used for the synthesis of the target compound involving a one-pot glycosylation and a protecting group manipulation. All intermediate reactions afford their products in high yield, and the glycos...
This paper examines a tractable real business cycle model with idiosyncratic productivity shocks and binding credit constraints on entrepreneurs. The model shows how firm volatility increases in combination with credit market development. It further generates the observed comovement of credit and firm volatility with output at business cycle frequencies in response to aggregate productivity sho...

Escherichia coli sequence type (ST)131 is an emerging disseminated public health threat implicated in multidrug-resistant extraintestinal infections worldwide. Although the majority of ST131 isolates belong to O25b:H4 serotype, new variants with different serotypes, STs using the discriminative multilocus sequence typing scheme of Pasteur Institute, and virulence-gene profiles (virotypes) have ...
