Virus-like particles (VLPs) are emerging as nanoscaffolds in a variety of biomedical applications including delivery of vaccine antigens and cargo such as mRNA to mucosal surfaces. These soft, colloidal, and proteinaceous structures (capsids) are nevertheless susceptible to mucosal environmental stress factors. We cross-linked multiple capsid surface amino acid residues using homobifunctional polyethylene glycol tethers to improve the persistence and survival of the capsid to model mucosal stressors.

Background: Urinary tract infections (UTIs) are among the most common bacterial infections worldwide, often caused by uropathogenic Escherichia coli. Multiple bacterial virulence factors or patient characteristics have been linked separately to progressive, more invasive infections. In this study, we aim to identify pathogen- and patient-specific factors that drive the progression to urosepsis by jointly analysing bacterial and host characteristics.

Purpose: There is a persistent rural physician shortage in the United States. Policies to scale up the health workforce in response to this shortage must include measures to draw and maintain existing and newly trained health care workers to rural regions. Prior studies have found that experience in community medicine in rural practice settings increases the likelihood of medical graduates practicing in those regions but have not accounted for selection bias.

The outermost surface of bacterial pathogens consists primarily of complex carbohydrate structures-polysaccharides, glycolipids, and glycoproteins. To raise a long-lasting and effective immune response against carbohydrate antigens, they generally require covalent attachment to an immunogenic carrier protein-a so-called glycoconjugate vaccine. One hurdle to the development of glycoconjugate vaccines is that carbohydrate antigens remain inaccessible to recombinant production.

Glycosylation of proteins profoundly impacts their physical and biological properties. Yet our ability to engineer novel glycoprotein structures remains limited. Established bacterial glycoengineering platforms require secretion of the acceptor protein to the periplasmic space and preassembly of the oligosaccharide substrate as a lipid-linked precursor, limiting access to protein and glycan substrates respectively.

Background And Objectives: Direct pharmaceutical marketing to physicians by pharmaceutical representatives is effective in changing behavior of health care providers, resulting in less evidence-based prescribing. Although much has been written about pharmaceutical marketing exposures among medical students, less is known about direct marketing exposures before students matriculate. This study examined the types of pharmaceutical representative direct marketing exposures for premedical students and where they occurred.

Polysialic acid (polySia) is a posttranslational modification found on only a handful of proteins in the central nervous and immune systems. The addition of polySia to therapeutic proteins improves pharmacokinetics and reduces immunogenicity. To date, polysialylation of therapeutic proteins has only been achieved in vitro by chemical or chemoenzymatic strategies.

Crucial virulence determinants of disease causing Neisseria meningitidis species are their extracellular polysaccharide capsules. In the serogroups W and Y, these are heteropolymers of the repeating units (→6)-α-d-Gal-(1→4)-α-Neu5Ac-(2→)n in NmW and (→6)-α-d-Glc-(1→4)-α-Neu5Ac-(2→)n in NmY. The capsule polymerases, SiaDW and SiaDY, which synthesize these highly unusual polymers, are composed of two predicted GT-B fold domains separated by a large stretch of amino acids (aa 399-762).

The enteropathogenic Escherichia coli K92 synthesizes a unique capsule consisting of polysialic acid (polySia) with alternating α2,8- and α2,9-linkages. The fact that a single enzyme is responsible for the synthesis of these alternating regioisomeric linkages raises questions as to how this controlled bifunctionality is achieved mechanistically. Aiming to identify the sequence elements responsible for dual regiospecificity, we have utilized a high-throughput polysialyltransferase (polyST) activity screen to explore the relevant sequence space between this enzyme and its close monofunctional homolog from E.
