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...

The 1.8 A resolution structure of the glycosyl-enzyme intermediate formed on the retaining beta-1,4-xylanase from Bacillus circulans has been determined using X-ray crystallographic techniques. The 2-fluoro-xylose residue bound in the -1 subsite adopts a 2,5B (boat) conformation, allowing atoms C5, O5, C1, and C2 of the sugar to achieve coplanarity as required at the oxocarbenium ion-like trans...

A bstract We present closed-form expressions of unrefined instanton partition functions for gauge groups type BCD as sums over Young diagrams. For SO( n ) groups, we provide a fivebrane web picture our formula based on the vertex-operator formalism topological vertex with new called O-vertex an O5-plane.

Escherichia coli serogroups O5, O15, O26, O45, O55, O76, O91, O103, O104, O111, O113, O118, O121, O123, O128, O145, O146, O157, O165, O172, and O177 are the O-antigen forms of the most clinically relevant Shiga toxin-producing E. coli (STEC) serotypes. In this study, three multiplex PCR assays able to specifically detect these 21 serogroups were developed and validated. For this purpose, the O-...

ABSTRACT Pulsars are rotating neutron stars that emit periodic electromagnetic radiation. While pulsars generally slow down as they lose energy, some also experience glitches: spontaneous increases of their rotational frequency. According to several models, these glitches can lead the emission long-duration transient gravitational waves (GWs). We present detection prospects for such signals by ...
