Escherichia coli J96 (O4:K6) was isolated from a human pyelonephritis patient. Here, we report the draft genome sequence of E. coli J96, which contains virulence genes, including adhesion factors, alpha-hemolysins, and cytotoxic necrotizing factor. J96 infects the kidney and bladder, making it an important tool for studying E. coli pathogenesis.
A strain of Vibrio parahaemolyticus, serotype O4/K4, that was Kanagawa positive and reactive in the rabbit ileal loop test, was isolated in low numbers from raw oysters implicated in a case of acute gastroenteritis. To our knowledge, this is the first report of the isolation of a Kanagawa-positive strain from suspect food in the United States.
We analyzed the prevalence and characteristics of Vibrio parahaemolyticus among patients with acute infectious diarrhea in the southern coastal region of China. V. parahaemolyticus was the leading cause of bacterial infectious diarrhea in this region during 2007-2012. Serotype O3:K6 strains were most common, followed by serotypes O4:K8 and O3:K29.
Uropathogenic Escherichia coli serotype O4:H5 isolates (ATCC 700414, 700415, 700416, and 700417) were recovered from women with first-time urinary tract infections. Here, we report the draft genome sequences for these four E. coli isolates, which are currently being used to validate food safety processing technologies.
have been structurally characterized, relatively few free Schiff bases have been similarly characterized.1 N-Substituted salicylaldimines show photochromism and thermochromism in the solid state. These effects are produced by intramolecular proton transfer associated with a change in the π-electron configuration.2 As part of a general study of tetradentate Schiff bases, we determined the struct...
Expression of Beta Protein 1 (BP1), a homeotic transcription factor, increases during breast cancer progression and may be associated with tumor aggressiveness. In our present work, we investigate the influence of BP1 on breast tumor formation and size in vitro and in vivo. Cells overexpressing BP1 showed higher viability when grown in the absence of serum (p < 0.05), greater invasive potential...
In situ X-ray absorption spectroscopy (XAS) is a powerful technique that can be applied to electrochemical systems, with the ability to elucidate the chemical nature of electrocatalysts under reaction conditions. In this study, we perform in situ XAS measurements on a bifunctional manganese oxide (MnOx) catalyst with high electrochemical activity for the oxygen reduction reaction (ORR) and the ...
We examined developmental characteristics of the ATP-binding cassette transporter ABCA2 (or ABC2) -expressing cells in rat spinal cord and peripheral nerves. In adult spinal cord, ABCA2 immunoreactivity was detected in lysosome-like organelles of mature oligodendrocyte cell bodies, and a single specific band was detected by Western blot analysis. In postnatal developing spinal cord, ABCA2 immun...
