Systems Biology and Pangenome of Salmonella O-Antigens. [PDF]
O-antigens are glycopolymers in lipopolysaccharides expressed on the cell surface of Gram-negative bacteria. Variability in the O-antigen structure constitutes the basis for the establishment of the serotyping schema. We pursued a two-pronged approach to

Electrospray ionization mass spectrometry (ESI‐MS) combined with thermodynamic modeling provides the first direct characterization of radium speciation in synthetic gastrointestinal biofluids. Free Ra2+ ions predominate with minimal protein binding and negligible EDTA complexation. Crown ethers enable effective Ra complexation.

Background: Derivatives of D-glucosamine and D-galactosamine represent an important family of the cell surface glycan components and their fluorinated analogs found use as metabolic inhibitors of complex glycan biosynthesis, or as probes for the study of

We examined the effects of oral glucosamine hydrochloride (GlcN), N-acetyl-D-glucosamine (GlcNAc) and D-glucose (Glc) administration on plasma total free amino acid (PFAA) concentrations in dogs. The PFAA concentrations increased in the control group and

The Pleiotropic Effects of Beneficial Mutations of Adapted Escherichia coli Populations [PDF]
Mutations that improve fitness in one environment can often be beneficial, deleterious, or neutral in alternative environments. When a single mutation effects fitness in multiple environments, it is said to be a pleiotropic, which can have important ...

Thermal Stabilization of Chitosan Yarn for Carbon Fiber Production
This study explores chitosan, a biopolymer derived from chitin, as a renewable precursor for carbon fiber production. The authors demonstrate that chitosan fibers can be successfully stabilized under controlled thermal conditions in air and nitrogen.

Applications and interest of chitin, chitosan and their derivatives in enology
This review treats of the possible use interest of chitin, chitosan and derivatives in enology. Chitosan and chitin are polysaccharide polymers containing more than 5 000 glucosamine and acetylglucosamine units, respectively, and their molecular weights ...

Immobilized photosensitizers for antimicrobial applications [PDF]
Photodynamic antimicrobial chemotherapy (PACT) is a very promising alternative to conventional antibiotics for the efficient inactivation of pathogenic microorganisms; this is due to the fact that it is virtually impossible for resistant strains to ...

This study firstly isolated a tuna‐derived gut probiotic Acinetobacter seifertii YFT067. Dietary administration of YFT067 played significant roles in promoting growth performance, SCFAs production, lipid absorption, and metabolism of the host, indicating YFT067 as a promising probiotic candidate for enhancing tuna aquaculture productivity through ...

Drosophila GFAT1 and GFAT2 enzymes encode obligate developmental functions
Glutamine: fructose-6-phosphate amidotransferase (GFAT) enzymes catalyse the first committed step of the hexosamine biosynthesis pathway (HBP) using glutamine and fructose-6-phosphate to form glucosamine-6-phosphate (GlcN6P). Numerous species (e.g. mouse,
