Structure of Bombyx mori chemosensory protein 1 in solution
Chemosensory Proteins (CSPs) represent a family of conserved proteins found in insects that may be involved in chemosensory functions. BmorCSP1 is expressed mainly in antennae and legs of the silkworm moth Bombyx morii and was cloned from antennal cDNA. Here we report the determination of the structure of Bombyx mori CSP1 (BmorCSP1) by NMR. The overall fold of BmorCSP1 is globular and comprises si
Sequential UV–biological degradation of chlorophenols
The sequential UV–biological degradation of a mixture of 4-chlorophenol (CP), 2,4-dichlorophenol (DCP), 2,4,6-trichlorophenol (TCP), and pentachlorophenol (PCP) was first tested with each pollutant supplied at an initial concentration of 50 mg l−1. Under these conditions, the chlorophenols were photodegraded in the following order of removal rate: PCP > TCP > DCP > CP with only CP and DCP remainin
Constitutive dependence in finite-element modelling of crack closure during fatigue
The influence of choice of constitutive relation on the prediction of crack-opening stress for fatigue cracks using the finite-element method is investigated and compared with experimental results. Two different experimentally obtained stress–strain relations for IN718 at 550 °C were used for fitting material parameters to the linear kinematic and the Bodner–Partom viscoplastic constitutive models
Multiple displacement amplification of DNA from human colon and rectum biopsies: Bacterial profiling and identification of Helicobacter pylori-DNA by means of 16S rDNA-based TTGE and pyrosequencing analysis
Amplifying bacterial DNA by PCR from human biopsy specimens has sometimes proved to be difficult, mainly due to the low amount of bacterial DNA present. Therefore, nested or semi-nested 16S rDNA PCR amplification has been the method of choice. In this study, we evaluate the potential use of whole genome amplification of total DNA isolated from human colon and rectum biopsy specimens, followed by 1
Two-dimensional gas-phase temperature measurements using phosphor thermometry
A new technique based on phosphor thermometry for measurements of two-dimensional gas-phase temperature, was examined as a new laser diagnostic. Calibration of Dy:YAG phosphor was carried out on the surface of a solid. The data were applicable for gas thermometry since the validation of the line intensity ratios method, showed good agreement with both the lifetime method and thermocouple data in a
Nursing and health care in Sweden
Sweden, one of the Nordic countries, has a long history of social justice and equality of access to health care. Nursing plays an important role in this and nursing education is of a high standard. The aim of this paper is to describe Sweden's health system and nursing within it, thereby giving Australian nurses information which may generate an interest in, and provide background for, collaborati
Analgetic effects of indomethacin (Confortid) compared to Ketogin in patients with acute cholecystitis
Acute Chlamydia pneumoniae infection causes coronary endothelial dysfunction in pigs.
Background: Coronary endothelial dysfunction contributes to the pathogenesis of acute coronary syndromes (ACSs). Acute Chlamydia pneumoniae infection has been epidemiologically associated with ACS. In this study, we investigated whether acute C. pneumoniae infection could alter the endothelial vasomotor function of porcine coronary vessels. Methods and results: Twenty pigs, 7–9 kg in weight, were
MHC-dependent and -independent modulation of endogenous Ly49 receptors on NK1.1+ T lymphocytes directed by T-cell receptor type.
Changes in fruitbody production of mycorrhizal and litter decomposing macromycetes in heavy-metal polluted coniferous forests in north Sweden
Basidiomycete fruitbodies growing in coniferous forests along a complex heavy metal pollution gradient in north Sweden were identified and counted over a 4 yr period. The dominant metals in the humus layer were As, Cd, Cu, Pb, and Zn. Pb occurred at the highest levels in a range of 80 to 8500 g g–1 dry wt. Both the number of fruitbodies and the number of fruiting species decreased strongly with in
Fibrillogenic oligomers of human cystatin C are formed by propagated domain swapping.
Cystatin C and the prion protein have been shown to form dimers via three-dimensional domain swapping, and this process has also been hypothesized to be involved in amyloidogenesis. Production of oligomers of other amyloidogenic proteins has been reported to precede fibril formation, suggesting oligomers as intermediates in fibrillogenesis. A variant of cystatin C, with a Leu(68)-> Gln substitutio
Dosimetry characteristics of degraded electron beams investigated by Monte Carlo calculations in a setup for intraoperative radiation therapy.
Degraded electron beams, as used for intraoperative radiation therapy (IORT) or similar complicated dosimetric situations, have different characteristics compared to conventional electron therapy beams. If international dosimetry protocols are applied in a direct manner to such degraded beams, uncertainties will be introduced in the absorbed dose determination. The Monte Carlo method has been used
Decay Constants of Pseudoscalar Mesons to Two Loops in Three-Flavor Partially Quenched ChPT
This paper presents a first study of the decay constants of the charged, or flavor-off-diagonal, pseudoscalar mesons to two loops for three flavors of sea quarks, in Partially Quenched Chiral Perturbation Theory (PQChPT). Explicit analytical expressions up to order p6 in the momentum expansion are given. The calculations have been performed within the supersymmetric formulation of PQChPT. We also
Improved mixing representation in Emanuel's convection scheme
Recent empirical and modelling studies suggest that mid-tropospheric relative humidity (RH) is an important controlling factor of deep atmospheric convection, which appears to be underestimated in present cumulus parametrizations. This indicates the possible presence of shortcomings in the way that entrainment is represented in such parametrizations. This matter was explored in the European Cloud

Forced spirometry reference values for Norwegian adults: the Bronchial Obstruction in Nord-Trondelag Study
The purpose of this study was to develop new prediction equations for flow/volume spirometry parameters in asymptomatic, never-smoking adults in Norway, and to assess any differences of these parameters when applying the new and most commonly used equation sets. Flow/volume spirometry was measured according to the American Thoracic Society criteria in 2,792 subjects aged > or = 20 yrs, randomly se
Platelets support pulmonary recruitment of neutrophils in abdominal sepsis
Objective. Recent findings Indicate that platelets not only regulate thrombosis and hemostasis but may also be involved in proinflammatory activities. Herein, we hypothesized that platelets may play a role in sepsis by activating and priming circulating neutrophils for subsequent recruitment Into the lung. Design: Prospective experimental study. Setting. University Hospital Research Unit. Subject.
A theory of stochastic harvesting in stochastic environments
We investigate how model populations respond to stochastic harvesting in a stochastic environment. In particular, we show that the effects of variable harvesting on the variance in population density and yield depend critically on the autocorrelation of environmental noise and on whether the endogenous dynamics of the population display over- or undercompensation to density. These factors interact
