Structure and gene cluster of the O-antigen of Escherichia coli O43
Carbohydrate Research, 2015The O-polysaccharide (O-antigen) of Escherichia coli O43 was isolated from the lipopolysaccharide and studied by chemical methods, including sugar analyses, Smith degradation, and solvolysis with anhydrous trifluoroacetic acid, along with (1)H and (13)C NMR spectroscopy.

Glycoconjugate Journal, 2020
A concise synthetic strategy has been developed for the synthesis of the pentasaccharide repeating unit of the cell wall O-antigen of Escherichia coli O43 strain involving stereoselective β-D-mannosylation and α-L-fucosylation using corresponding trichloroacetimidate intermediates and perchloric acid supported over silica (HClO4-SiO2) as glycosylation ...

O43 Immersive endoscopy nurse training provides sustainable confidence increase in the job role
Oral presentations, 2022Introduction Bowel cancer screening age extension, 'faster diagnosis' and COVID-related backlog all increase demand on endoscopy services. A competent workforce is central to endoscopy delivery but service pressure, lack of dedicated training time, and ...

Total Synthesis of Vibrio Cholerae O43 Tetrasaccharide Repeating Unit
The Journal of Organic ChemistryVibrio cholerae is a pathogen responsible for the deadly pandemic - cholera. The glycans present on the surface of various strains of V. cholerae are considered as potential vaccine candidates. The tetrasaccharide repeating unit (RU) of V. cholerae O43 is decorated with less-explored rare deoxy amino sugars like d-quinosamine and d-viosamine, along ...

The Structure and Serological Specificity of Proteus mirabilis O43 O Antigen
FEBS Journal, 1995On the basis of sugar analysis and NMR spectroscopy, including selective spin-decoupling, one-dimensional NOE, two-dimensional homonuclear and 13C,1H-heteronuclear correlation spectroscopy, the following structure of the acidic O-specific polysaccharide of Proteus mirabilis O43 was established: -->4)-alpha-D-GalpA-(1-->3)-alpha-D-GalpA-(1-->3)-alpha-D ...

Journal of Hypertension
Background: Hypertension is the cardiovascular risk factor that accounts for most preventable deaths worldwide. Implementation of clinical practice guidelines (CPG) reduces variability in care and improves outcomes. In Colombia, clinicians’ adherence to recommendations is rarely reported. The aim of this study was to assess the

O43 Therapeutic vaccination against breast cancer in a transgenic mouse model
Human Immunology, 2017Aim Class I MHC mediated immune responses to tumors are complex and poorly understood, and enhanced tools for studying tumor immunity are needed. One such tool is the MMTV-PyMT mouse – a breast cancer model in an immune-competent FVB strain. PyMT is a viral oncogene expressed as a transgene under a mammary gland-selective promoter.
