On the Ga II and Ga III resonance lines and the implication for chemical stratification in HGMN stars

The gallium abundance in HgMn stars has been reported to be different for analyses conducted from spectral lines in the optical versus those from the ultraviolet. We pursue this ultraviolet-optical discrepancy from a line-blending perspective by investigating the Hubble Space Telescope (HST) Space Telescope Imaging Spectrograph (STIS) spectrum of the sharp-lined HgMn binary star chi Lup. Its galli

Myofibroblast accumulation correlates with the formation of fibrotic tissue in a rat air pouch model.

OBJECTIVE: The pathogenesis of arthritic joints involves cartilage degradation and pannus formation. It is well known that pannus influences the cartilage; however, the mechanism behind how the degrading cartilage interacts with pannus is not well known. To investigate this interplay, the expression of extracellular matrix (ECM) components in pannus and the degrading cartilage was analyzed. METHOD

Consequences of axillary recurrence after conservative breast surgery

Background: The aim was to study the incidence, time course and prognosis of patients who developed axillary recurrence after breast-conserving surgery, and to evaluate possible risk factors for axillary recurrence and prognostic factors after axillary recurrence. Methods: In a population-based cohort of 6613 women with invasive breast cancer who had breast-conserving surgery between 1981 and 1990

Internationalisation in the Swedish nurse education from the perspective of teachers involved: An interview study

This paper presents results from an interview investigation with teachers in Swedish nurse education especially interested in internationalising the education. The aim has been to study teachers' understandings and experiences of internationalisation against the backdrop of the strong concern for internationalisation expressed in policy documents. The results are seen in the context of globalisati

Evaluation of PIT-tagging in cyprinids.

Laboratory and field experiments were used to investigate how different marking procedures, with 23 mm PIT (passive integrated transponders) – tags, affected mortality, body condition and tag expulsion in small roach Rutilus rutilus and rudd Scardinus erythrophthalmus (117 to 163 mm total length). In a laboratory experiment mortality was low (≤ 6%) and only occurred among fishes that had their inc

Environmental systems analysis of biogas systems - Part II: The environmental impact of replacing various reference systems

This paper analyses the overall environmental impact when biogas systems are introduced and replace various reference systems for energy generation, waste management and agricultural production. The analyses are based on Swedish conditions using a life-cycle perspective. The biogas systems included are based on different combinations of raw materials and final use of the biogas produced (heat, pow

Ethanol stimulates basal and serotonin-induced formation of [32P]phosphatidic acid in human platelets

The addition of serotonin to preparations of 32P-labelled human platelets resulted in a time- and dose-dependent hydrolysis of [32P]phosphatidylinositol 4,5-bisphosphate (PIP2) and formation of [32P]phosphatidic acid (PA). This response was inhibited by the serotonin2 receptor antagonist ritanserin, indicating that the stimulation was mediated via the serotonin2 receptor. The addition of 50-150 mM

Dystroglycan: a possible mediator for reducing congenital muscular dystrophy?

alpha-Dystroglycan is a highly glycosylated peripheral protein forming a complex with the membrane-spanning beta-dystroglycan and establishing a connection between the extracellular matrix and the cytoskeleton. In skeletal muscle, as part of the larger dystrophin-glycoprotein complex, dystroglycan is believed to be essential for maintaining the structural and functional stability of muscle fibers.

Mechanical degradation and changes in conformation of hydrophobically modified starch

In this paper, we study the mechanical degradation and changes in conformation of a branched ultrahigh molar mass biomacromolecule, hydrophobically modified starch, as caused by high-pressure homogenization. The characterization was performed with asymmetrical flow field-flow fractionation (AsFlFFF) with multiangle light scattering (MALS) and refractive index detection. The starch which had been c

Inhibitor treatment in haemophilas A and B: Summary statement for the 2006 International Consensus Conference

Participants in an international conference on the management of haemophilia patients with inhibitors developed a jointly authored summary of the findings and conclusions of the conference. Current knowledge of the genetic and immunologic mechanisms underlying inhibitor development was briefly summarized. Concerning the purported treatment-related risk factors, conference participants commented on

Stratigraphical distribution of Campanian and Maastrichtian mosasaurs in Sweden - evidence of an intercontinental marine extinction event?

Remains of late Campanian and earliest Maastrichtian mosasaurs from southern Sweden are illustrated and briefly described. Plioplatecarpus sp. and Prognathodon sp. have been identified from strata of middle late Campanian age, while earliest Maastrichtian deposits contain remains of Mosasaurus cf. lemonnieri and Plioplatecarpus cf. primaevus. Available data suggest that the mosasaur group increase

Suppression of high-p(T) neutral pion production in central Pb+Pb collisions at root s(NN)=17.3 GeV relative to p+C and p+Pb collisions

Neutral pion transverse momentum spectra were measured in p+C and p+Pb collisions at root s(NN) = 17.4 GeV at midrapidity (2.3 less than or similar to eta(lab)less than or similar to 3.0) over the range 0.7 less than or similar to p(T)less than or similar to 3.5 GeV/c. The spectra are compared to pi(0) spectra measured in Pb+Pb collisions at root s(NN) = 17.3 GeV in the same experiment. For a wide

Hybrid Control of Homogeneous Charge Compression Ignition (HCCI) Engine Dynamics

The homogeneous charge compression ignition ( HCCI) combustion engine principle lacks direct ignition timing control, instead the auto-ignition depends on the operating condition. Since auto-ignition of a homogeneous mixture is very sensitive to operating conditions, fast combustion phasing control is necessary for reliable operation. For this paper, a six-cylinder heavy-duty HCCI engine was contr

The Boundary Work of Commercial Friendship

With the aim to reconsider lifestyle values in relation to economic rationality in small tourism and hospitality businesses, we focus on the “commercial home” as a site where boundaries between personal and commercial values are constantly performed in practice. Through an interactionist analysis of the narrative of a B&B and gallery owner, we illustrate the emergence of intimacy as a commerci

Mechanism of pathogen-specific TLR4 activation in the mucosa: Fimbriae, recognition receptors and adaptor protein selection.

The mucosal host defence discriminates pathogens from commensals, and prevents infection while allowing the normal flora to persist. Paradoxically, Toll-like receptors (TLR) control the mucosal defence against pathogens, even though the TLR recognise conserved molecules like LPS, which are shared between pathogens and commensals. This study proposes a mechanism of pathogen-specific mucosal TLR4 ac
