Behaviour-focused pain coping: consistency and convergence to work capability of the swedish version of the chronic pain coping inventory.

The aim was to study the psychometric properties of the Swedish version of the Chronic Pain Coping Inventory. The material consisted of a group of 100 subjects recruited from a large population study. Pain status and the absence of pain-related sick leave during the previous year conditioned inclusion. Another group comprised 160 patients on the long-term sick list and who had been referred to a m

Carotenoid and pheophytin on semiconductor surface: Self-assembly and photoinduced electron transfer

Self-assembling of a carotenoid and pheophytin a into a supramolecular system was observed on the surface of nanocrystalline TiO2, and the photoinduced electron-transfer reactions within the system were studied by means of femtosecond transient absorption and laser flash photolysis techniques. Excitation of the pheophytin moiety results in ultrafast electron transfer from carotenoid to the excited

Abnormal Ca2+-calmodulin-dependent protein kinase II function mediates synaptic and motor deficits in experimental parkinsonism

The NMDA receptor complex represents a key molecular element in the pathogenesis of long-term synaptic changes and motor abnormalities in Parkinson's disease (PD). Here we show that NMDA receptor 1 (NR1) subunit and postsynaptic density (PSD)-95 protein levels are selectively reduced in the PSD of dopamine (DA)-denervated striata. These effects are accompanied by an increase in striatal levels of

Capacity of MIMO systems with antenna selection

We consider the capacity of multiple-input multiple-output systems with. reduced complexity. One link-end uses all available antennas, while the other chooses the L out of N antennas that maximize capacity. We derive an upper bound on the capacity that can be expressed as the sum of the logarithms of ordered chi-square-distributed variables. This bound is then evaluated analytically and compared t

Telomerase in yeast

The ribonucleoprotein enzyme telomerase synthesizes telomeric DNA by copying an internal RNA template sequence. The telomerase activities of the yeasts Saccharomyces castellii and Saccharomyces cerevisiae-with regular and irregular telomeric sequences, respectively-have now been identified and characterized. The S. cerevisiae activity required the telomerase RNA gene TLC1 but not the EST1 gene, bo

Effects of unloading of multiple necking in tensile bars

The distribution of necks in slender structures obtained using high rate deformation often differs from the distribution obtained under quasistatic conditions. Initial thickness imperfections are often used to initiate necking at certain locations along a specimen surface. At sufficiently large deformation rates, necks may develop at sites that correlate weakly or not at all with the sites of the

Monochromatic phototherapy in elderly patients: A new way of treating chronic pressure ulcers?

Background and aims: Monochromatic pulsating light may have effects of importance for wound healing, and promising results were obtained in an open study on the healing of pressure ulcers, which motivated the present study. Methods: One hundred and sixty-four in- and outpatients with grade II and III ulcers were treated with monochromatic pulsating light or placebo over the ulcerated area, accordi

Blood-brain barrier leakage and brain edema in stroke-prone spontaneously hypertensive rats. Effect of chronic sympathectomy and low protein/high salt diet

Brain edema associated with severe chronic hypertension was studied in stroke-prone spontaneously hypertensive rats (SHRSP), 5 to 9 months of age. Blood-brain barrier (BBB) leakage sites and intracerebral spreading pathways for plasma proteins were delineated by an intravenously (i.v.) injected exogenous dye tracer (Evans blue), known to form a complex with albumin in blood, and by immunohistochem

Constructing a Swedish conflict prevention policy based on a powerful idea and successful practice

The story of how conflict prevention became an integral and legitimate part of Swedish foreign policy illustrates the relationship between successful practices and powerful ideas. This article suggests that the demonstration of an idea in practice empowers the idea and contributes not only to its selection, but also to its framing and institutionalization within foreign policy. Hence, the article

Variational Problems and Level Set Methods in Computer Vision - Theory and Applications

Current state of the art suggests the use of variational formulations for solving a variety of computer vision problems. This thesis deals with such variational problems which often include the optimization of curves and surfaces. The level set method is used throughout the work, both as a tool in the theoretical analysis and for constructing practical algorithms. One frequently occurring example

PCB and DDT in laminated sediments from offshore and archipelago areas of the NW Baltic Sea

Temporal trend studies of PCBs and DDTs in two annually laminated sediment cores from the offshore NW Baltic proper and the Stockholm archipelago demonstrate that studies of laminated sediments are useful tools for detecting time trends of HOCs. The concentration trends of PCBs and DDTs, on a dry weight basis, from the two cores show quite large similarities to trends reported in pelagic biota fro

Quality of life, morbidity, and mortality after surgical intensive care: a follow-up study of patients treated for abdominal sepsis in the surgical intensive care unit.

OBJECTIVE: To evaluate the long-term outcome of patients treated in the surgical intensive care unit (SICU) for abdominal sepsis. DESIGN: Retrospective study. SETTING: University hospital, Sweden. SUBJECTS: 210 consecutive patients treated for abdominal sepsis in the SICU at Lund University Hospital during the period January 1983 to December 1995. MAIN OUTCOME MEASURES: Background information, mor

Hydrocarboxylation of olefins using an amphiphilic palladium catalyst, activity and recycling properties NMR identification of some reaction intermediates

The high solubility in acidic solutions of N-bis(N',N'-diethyl-2-aminoethyl)-4-aminomethylphenyl-diphenylphosphine (N3P) make it a suitable candidate for study and comparison to the more commonly studied trisulfonated triphenylphosphine (TPPTS) ligand in the palladium catalysed aqueous hydrocarboxylation reaction. The catalyst employing N3P shows an inverted regioselectivity compared to the TPPTS

Essays on the Demand for Alcohol in Sweden - Review and Applied Demand Studies

The review and Paper I present applications of economics to the use of alcohol. The review considers the demand for alcohol. The first paper also considers taxes and other alcohol policy measures, social costs and economic evaluations. In Paper II, an Almost Ideal Demand System Model is used for the study of the demand for alcoholic beverages in Sweden during the years 1985-1995. The results indi

The Anglo-American financial influence on CEO compensation in non-Anglo-American firms

This study examines the impact of Anglo-American financial markets on CEO compensation. Starting from a sample of Norwegian and Swedish listed firms, we analyse this effect as manifested in the capital market (Anglo-American cross-listing) and in the market for corporate control (Anglo-American board membership). These effects are analysed together with the geographically broader effect of the pro

Enhanced Ribosome and tRNA Contents in Escherichia coli Expressing a Truncated Vitreoscilla Hemoglobin Mutant Analyzed by Flow Field-Flow Fractionation

The ribosome and tRNA levels of Escherichia coli cells, transformed with a native or mutated Vitreoscilla hemoglobin genes (vhb), were investigated using asymmetrical flow field-flow fractionation (AFFFF). Mutagenesis of vhb by error-prone PCR was carried out to alter the growth behavior of microaerobically cultivated native VHb-expressing E. coli. A VHb mutant, pVMT1, was identified, which was ab

Differences in exercising limb blood flow variability between cardiac and muscle contraction cycle related analysis during dynamic knee extensor

Aim. Blood flow in peripheral conduit arteries during steady-state, dynamic exercise, can be estimated noninvasively with Doppler ultrasound, by measuring the conduit arterial diameter and the mean blood velocity averaged over consecutive cardiac beat-by-beat cycles (BBcycle) or muscle contraction-relaxation cycles (CRcycle). The precise impact fluctuations in the 1-BBcycle- or 1-CRcycle-rate may
