Micellar Sphere-to-Rod Transition in an Aqueous Triblock Copolymer System. A Dynamic Light Scattering Study of a Translational and Rotational Diffusion
Social participation and coronary heart disease: a follow-up study of 6900 women and men in Sweden
Few studies have examined the relationship between social, cultural and religious participation, political empowerment and coronary heart disease (CHD). The aim of this study was to examine whether low social participation, as described in a social participation index, predicted incidence rates of CHD. This is a follow-up study, from 1990-91 to 31 December 2000, of 6861 Swedish women and men, who
Function and Morphology of the Antennal Lobe: New Developments
The antennal lobe of insects has emerged as an excellent model for olfactory processing in the CNS. In the present review we compile data from areas where substantial progress has been made during recent years: structure-function relationships within the glomerular array, integration and blend specificity, time coding and the effects of neuroactive substances and hormones on antennal lobe processi

Consumer-resource matching in a food chain when both predators and prey are free to move
The classical theory of the ideal free distribution (IFD) predicts that the spatial distribution of consumers should follow the distribution of the resources they depend on. Here, we study consumer-resource matching in a community context. Our model for the community is a food chain with three levels. We study whether the primary consumers are able to match resources both under predation risk and
Input rates, decay losses and accumulation rates of carbon in bogs during the last millennium: internal processes and environmental changes
In peatlands the balance between litter input and decay loss in the oxic acrotelm determines the rate of carbon input to the anoxic catotelm with carbon lost at very slow rate. In the acrotelm the C/N-quotient decreases with depth and indicates the loss of carbon from the acrotelm. On one boreo-nemoral and three subalpine ombrotrophic bogs in Sweden the carbon losses in the acrotelm plus the appar
Activation of TAFI on the Surface of Streptococcus pyogenes Evokes Inflammatory Reactions by Modulating the Kallikrein/Kinin System
Bacteria-controlled regulation of host responses to infection is an important virulence mechanism that has been demonstrated to contribute to disease progression. Here we report that the human pathogen Streptococcus pyogenes employs the procarboxypeptidase TAR (thrombin-activatablefibrinolysis inhibitor) to modulate the kallikrein/kinin system. To this end, bacteria initiate a chain of events star
Evaluation of parameters for monitoring an anaerobic co-digestion process
The system investigated in this study is an anaerobic digester at a municipal wastewater treatment plant operating on sludge from the wastewater treatment, co-digested with carbohydrate-rich food-processing waste. The digester is run below maximum capacity to prevent overload. Process monitoring at present is not extensive, even for the measurement of on-line gas production rate and off-line pH. M
Vortex wakes of birds: recent developments using digital particle image velocimetry in a wind tunnel
A flying animal generates a trail of wake vortices that contain information about the time history and magnitude of aerodynamic forces developed on the wings and body. Methods for visualising and recording wake vortices have been developed, allowing quantitative measurements by digital particle image velocimetry (DPIV). Results from DPIV experiments in a wind tunnel are presented for four passerin
Developing HMI components for a driver assistance system for safe speed and safe distance
This paper describes a pre-screening procedure that was carried out with a number of candidate Human-Machine-Interaction solutions in three different modes (visual, auditory and haptic) for the concepts of “safe speed and safe distance” (referred to as SASPENCE) of an Advanced Driver Assistance System (termed as ADAS). This procedure was performed simultaneously in two European countries, Sweden a
Signalling pathways regulating inducible nitric oxide synthase expression in human kidney epithelial cells.
Comparative study of various algorithms for the merging of parton showers and matrix elements in hadronic collisions
We compare different procedures for combining fixed-order tree-level matrix-element generators with parton showers. We use the case of W-production at the Tevatron and the LHC to compare different implementations of the so-called CKKW and MLM schemes using different matrix-element generators and different parton cascades. We find that although similar results are obtained in all cases, there are i
System for integrated interstitial photodynamic therapy and dosimetric monitoring
Photodynamic therapy for the treatment of cancer relies on the presence of light, sensitizer and oxygen. By monitoring these three parameters during the treatment a better understanding and treatment control could possibly be achieved. Here we present data from in vivo treatments of solid skin tumors using an instrument for interstitial photodynamic therapy with integrated dosimetric monitoring. B
Spatiotemporal pattern of striatal ERK1/2 phosphorylation in a rat model of L-DOPA-induced dyskinesia and the role of dopamine D1 receptors
Background: We examined the activation pattern of extracellular signal-regulated kinase 1 and 2 (ERK1/2) and its dependence on D1 versus D2 dopamine receptors in hemiparkinsonian rats treated with 3,4-dihydroxyphenyl-L-alanine (L-DOPA). Methods: 6-Hydroxydopamine-lesioned rats were treated acutely or chronically with L-DOPA in combination with antagonists for D1 or D2 receptors. Development of dys
The Brussels Declaration: the need for change in asthma management
Asthma is a highly prevalent condition across Europe and numerous guidelines have been developed to optimise management. However, asthma can be neither cured nor prevented, treatment choices are limited and many patients have poorly controlled or uncontrolled asthma. The Brussels Declaration on Asthma, sponsored by The Asthma, Allergy and Inflammation Research Charity, was developed to call attent
The granulation of a tablet formulation in a high-speed mixer, Diosna P25. Influence on intra-granular porosity and liquid saturation
Intragranular porosity and liquid saturation were influenced by the impeller speed, the loss-on-drying of starch, the added amount of water and the drug concentration. A reduction of the impeller speed and the drug concentration decreased the porosity and increased the liquid saturation. Response surface contours were plotted.
Linear response functions for coupled cluster/molecular mechanics including polarization interactions.
We present the first implementation of linear response theory for the coupled cluster/molecular mechanics (CC/MM) method. This model introduces polarization effects into a quantum mechanical/molecular mechanical (QM/MM) framework using a self-consistent procedure while electrostatic effects are modeled by assigning partial charges to the MM molecules and a van der Waals potential describes dispers
Satisfaction with rollators among community-living users: a follow-up study.
Purpose: Rollators are used in order to make mobility possible for people with restricted walking ability. The use of rollators is increasing, but little is known about outcomes. The aim of this study was to investigate users' satisfaction with rollators. Method: A follow-up study was carried out in seven Danish municipalities. One month after they got their device, 89 users of rollators were inte
A pooled analysis of karyotypic patterns, breakpoints and imbalances in 783 cytogenetically abnormal multiple myelomas reveals frequently involved chromosome segments as well as significant age- and sex-related differences.
The cytogenetic features (ploidy, complexity, breakpoints, imbalances) were ascertained in 783 abnormal multiple myeloma (MM) cases to identify frequently involved chromosomal regions as well as a possible impact of age/sex. The series included MM patients from the Mitelman Database of Chromosome Aberrations in Cancer and from our own laboratory. Hyperdiploidy was most common, followed by hypodipl
