Glucarate, an oxidized product of glucose, is a major serum organic acid in humans. Still, its role as a carbon source for a pathogen colonizing hosts has not been studied. We detected high-level expression of a potential glucarate permease encoding gene gudT when Salmonella enterica serovar Typhimurium are exposed to hydrogen gas (H(2)), a gaseous by-product of gut commensal metabolism. A gudT...

AIMS The present study aimed to test the capability of real-time three-dimensional echocardiography (RT3DE) in characterizing early abnormalities of left ventricular (LV) structure and function in native, untreated hypertensive patients. METHODS AND RESULTS Thirty-eight newly diagnosed, never-treated hypertensives (H) and 38 healthy controls (C) underwent both standard echo-Doppler and RT3DE ...

We isolated three strains of canine distemper virus (CDV)--the Ueno, Hamamatsu, and Yanaka strains--from dogs in Japan and analysed the molecular properties of their haemagglutinin (H) proteins. Immunoprecipitation of all three strains with a monoclonal antibody revealed H proteins with molecular masses of 84 kDa, which differs from the molecular mass (78 kDa) of the H protein of the Onderstepo...

A bacterium designated Pseudonocardia sp. strain ENV478 was isolated by enrichment culturing on tetrahydrofuran (THF) and was screened to determine its ability to degrade a range of ether pollutants. After growth on THF, strain ENV478 degraded THF (63 mg/h/g total suspended solids [TSS]), 1,4-dioxane (21 mg/h/g TSS), 1,3-dioxolane (19 mg/h/g TSS), bis-2-chloroethylether (BCEE) (12 mg/h/g TSS), ...

A whitish Gram-negative, motile, aerobic bacterium, designated strain H 14(T), was isolated from seawater collected at St Kilda beach in Port Phillip Bay, Melbourne, Australia. Analysis of 16S rRNA gene sequences revealed that the organism belonged to the Roseobacter lineage of the class Alphaproteobacteria, forming a distinct evolutionary lineage at the genus level. Strain H 14(T) was distantl...

BMS 284756 penetrated well into inflamed meninges (44% +/- 11%) and produced good bactericidal activity (-0.82 +/- 0.22 Delta log(10) CFU/ml. h) in the treatment of experimental meningitis in rabbits due to a penicillin-sensitive strain. BMS 284756 monotherapy had a greater potency than the standard regimen of ceftriaxone and vancomycin (-0.49 +/- 0.08 Delta log(10) CFU/ml. h) against a penicil...

the basis of reaction to transplantation, indicated that the antigens produced by these alleles were slightly different in nature. The H-f@? locus is complicated by the presence of composite alleles. Originally, the type allele char acteristic of the A strain was designated simply H-L@. Later, by genetic crosses, it was found that animals of the heterozygous genotype H-@'/H-P@, irrespective of ...

A field strain of H. contortus, already resistant to benzimidazole anthelmintics, was also found to be slightly resistant to rafoxanide. This is apparently the first report of resistance to rafoxanide in a field strain of H. contortus.

In this study, the effect of finite strain on bending of the geometrically nonlinear of micro laminated composite Euler-Bernoulli beam based on Modified Couple Stress Theory (MCST) is studied in thermal environment. The Green-Lagrange strain tensor according to finite strain assumption and the principle of minimum potential energy is applied to obtain governing equation of motion and boundary c...
