The immunogenicity to several meningococcal polysaccharide-protein conjugates was evaluated in mice. The purified polysaccharide from N. meningitidis serogroup C (PsC) was linked to different quantities of outer membrane vesicle from N. meningitidis serogroup B (OMV) (3, 6 and 9 mg) as carrier protein, via carbodiimide-mediated reaction. The conjugates were inoculated in Balb/c mice in three do...

The outer membrane of Borrelia hermsii has been shown by freeze-fracture analysis to contain a low density of membrane-spanning outer membrane proteins which have not yet been isolated or identified. In this study, we report the purification of outer membrane vesicles (OMV) from B. hermsii HS-1 and the subsequent identification of their constituent outer membrane proteins. The B. hermsii outer ...

We consider the Online Boolean Matrix-Vector Multiplication (OMV) problem studied by Henzinger et al. [STOC’15]: given an n× n Boolean matrix M, we receive n Boolean vectors v1, . . . ,vn one at a time, and are required to output Mvi (over the Boolean semiring) before seeing the vector vi+1, for all i. Previous known algorithms for this problem are combinatorial, running in O(n3/ log2 n) time. ...

this review presents a brief outline of our current knowledge of the structure and chemical composition of the outer membrane vesicles (omvs), originating from the surface of gram negative bacteria including their outer membrane proteins and lipopolysaccharides. moreover, the functional roles and applications of omvs in medical research such as omv-based vaccines, omv adjuvants properties, omv ...

Bacterial outer membrane vesicle (OMV)-mediated delivery of proteins to host cells is an important mechanism of host-pathogen communication. Emerging evidence suggests that OMVs contain differentially packaged short RNAs (sRNAs) with the potential to target host mRNA function and/or stability. In this study, we used RNA-Seq to characterize differentially packaged sRNAs in Pseudomonas aeruginosa...

BACKGROUND & AIMS Clinical trials evaluating second-generation direct-acting antiviral agents (DAAs) have shown excellent rates of sustained virologic response (SVR) and good safety profiles in patients with chronic hepatitis C virus (HCV) genotype 1 infection. We aimed to investigate the effectiveness and safety of two oral DAA combination regimens, ombitasvir/paritaprevir/ritonavir plus dasab...

Enterohemorrhagic Escherichia coli (EHEC) strains cause diarrhea and hemolytic uremic syndrome resulting from toxin-mediated microvascular endothelial injury. EHEC hemolysin (EHEC-Hly), a member of the RTX (repeats-in-toxin) family, is an EHEC virulence factor of increasingly recognized importance. The toxin exists as free EHEC-Hly and as EHEC-Hly associated with outer membrane vesicles (OMVs) ...

Porin (PorB) is a major outer membrane protein produced by all Neisseria gonorrhoeae strains and has been a focus of intense interest as a vaccine candidate. In this study, the immunogenicity of PorB in mice was investigated after several immunization regimens. Outer membrane vesicles (OMV), recombinant renatured PorB (rrPorB), and PorB-expressing Venezuelan equine encephalitis (VEE) virus repl...

Recent research has focused on the biological role of outer membrane vesicles (OMVs), which are derived from the outer membranes (OMs) of Gram-negative bacteria, and their potential exploitation as therapeutics. OMVs have been characterized in many ways and functions. Until recently, research focused on hypothetical and empirical models that addressed the molecular mechanisms of OMV biogenesis,...
