Streptococcus spp. are important causes of infective endocarditis but challenging in species identification. This study compared identification based on sequence determination of the rnpB gene with 2 systems of matrix-assisted laser desorption ionization-time of flight mass spectrometry, MALDI Biotyper (Bruker) and VITEK MS IVD (bioMérieux). Blood culture isolates of viridans streptococci from 63
Several psychiatric disorders may be characterized by peripheral telomere shortening. However, it is unclear whether telomere shortening is associated with these psychiatric disorders per se or, rather, with underlying dimensional parameters that are often, but not necessarily, associated with them. We explored the association between dimensional psychopathological measures and telomere length (TL
We examined the effect of 17alpha-ethinylestradiol on immunity of the Western fence lizard, Sceloporus occidentalis. Injection of 17alpha-ethinylestradiol resulted in dose-dependent suppression of peripheral blood leukocyte levels as determined by cell counts, whereas total spleen cell levels were decreased only at higher doses of 17alpha-ethinylestradiol. In contrast, spleen cell proliferation wa
Recent progress on the nature of short-duration gamma-ray bursts has shown that a fraction of them originate in the local Universe. These systems may well be the result of giant flares from soft gamma-repeaters (highly magnetized neutron stars commonly known as magnetars). However, if these neutron stars are formed via the core collapse of massive stars then it would be expected that the bursts sh
The growing field of biotechnology is in constant need of binding proteins with novel properties. Not just binding specificities and affinities but also structural stability and productivity are important characteristics for the purpose of large-scale applications. In order to find such molecules, libraries are created by diversifying naturally occurring binding proteins, which in those cases serv
The colorimetric 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay was standardized for direct detection of rifampin-resistant Mycobacterium tuberculosis in sputum samples. The sensitivity and specificity of the direct MTT assay matched those of the standard indirect susceptibility assay on 7H10 medium, and interpretable results were obtained for 98.5% of the samples within
The solution properties of two water-soluble polymers, poly(acrylic acid) (PAA), covalently labeled with the fluorescent hydrophobic dye naphthalene (Np), have been investigated in water:organic solvent mixtures. The naphthalene chromophores have been randomly attached, onto the polymer, with two different degrees of labeling. Fluorescence measurements (steady-state and time-resolved) have been us
To assess the manifestation and location of airway inflammation in smokers with chronic bronchitis (CB) or chronic obstructive pulmonary disease (COPD), we lavaged the airways of 12 smokers with CB and 11 smokers with COPD and coexisting CB (OCB). For comparison, the airways of 5 asymptomatic smokers (AS) and 10 healthy nonsmokers (HNS) were lavaged. In all cases, the first lavage aliquot, labeled
A new immunoassay for the detection of hepatitis C core antigen (HCVcoreAg) in peripheral blood during serological window-phase was evaluated among healthy blood donors, commercially available hepatitis C virus (HCV) seroconversion panels and in-house specimens from individuals undergoing seroconversion. Among 1964 low-risk blood donor samples, seven samples were initially reactive but only one wa
A hepatitis C virus (HCV) genotyping PCR assay based on type-specific primers was expanded to include genotype 6a as well as genotypes 1a, 1b, 2a, and 3a. The nucleotide sequences of a 194-bp fragment in the center of the HCV core gene showed that the homologies between genotype 6a and genotypes 1a, 1b, 2a, 2b, 3a, and 5 were 81.2, 82.1, 73.8, 77.3, 81.4, and 78.9%, respectively. A high degree of
Two different antennas for use in implanted pacemakers are analyzed by simulation and measurement. The analysis was made with an FDTD-code. The simulations and measurements show good agreement. The SAR values for both the antennas are within the limits recommended by ICNIRP when the antenna is fed with 25 uW.
Popular Abstract in Swedish Kroppen som socialt fenomen har inte varite ett dcentralt tema inom sociologin. Detta försöker Lars-Erik Alkvist komma till rätta med, på grundval av en omläsning av Max Webers sociologi utifrån temat kroppens sociologi. Författaren menar att det hos Weber finns en dold med dock närvarande förståelse av kroppens sociala sammanhang. Men Webers förståelse av kroppen sitteThis thesis is about the social body in sociology, represented by the classical sociologist Max Weber. Traditional sociology has not taken the body into account. The body has been considered to belong to the realm of the natural sciences. Sociology has seen the body merely as an instrument or a tool for social action. The mind/body dichotomy, homo duplex, prevails in sociology. The purpose of this
Infants treated in neonatal intensive care units suffer an increased risk for invasive candidiasis, but the diagnosis is sometimes difficult. D-arabinitol is a metabolite of most pathogenic Candida species. An elevated urine D-arabinitol/L-arabinitol (DA/LA) ratio is a sensitive sign of invasive candidiasis in children with cancer, but the method has not been previously evaluated for newborn infan
The outer membrane protein Ail of Yersinia pestis mediates several virulence functions, including serum resistance. Here, we demonstrate that Ail binds C4b-binding protein (C4BP), the primary fluid-phase regulator of the classical and lectin pathways. Non-covalent binding of C4 and C4b to Ail was also observed. C4BP bound to Ail can act as a cofactor to the serine protease factor I (fI) in the cle
