Increased concentrations of nitrate in forest soil water after windthrow in southern Sweden
In January 2005, south-west Sweden was hit by a severe storm that caused large damage to the forests through massive windthrow. The aim of this study was to assess the effect of this windthrow on nitrate concentrations in the soil water below the root zone on 33 forest monitoring plots within the Swedish Throughfall Monitoring Network (SWETHRO). These sites were damaged to different extents by the

Common risk factors associated with acute myocardial infarction: Population-based studies with a focus on gender differences
Popular Abstract in Swedish År 2008 insjuknade 37 156 personer i akut hjärtinfarkt i Sverige och av dessa dog 10 509 personer. Akut hjärtinfarkt är därmed den vanligaste dödsorsaken i Sverige, men även i resten av världen. Generellt sett insjuknar män ungefär 10 år tidigare än kvinnor i hjärtinfarkt och män har därför en högre total risk att insjukna, även om hjärtinfarkt är den vanligaste dödsorsThe overall aim of this thesis was to explore how the risk for AMI, and the associations between several of its risk factors, differs by gender. Information was collected from four Swedish cohorts: one patient cohort from Skara (1992-1993, n=1149) and three population-based cohorts, i.e. from Skara (1993-1994, n=1109), Vara (2001-2004, n=1811), and Skövde (2003-2005, n=1005). Participants were exa
Home, health and participation for community living people with disability
The aim of this thesis was to contribute to the understanding of aspects related to home, health and participation for community living people with disability and identify different groups with different needs for interventions. Study I used focus groups to explore aspects of importance for participation. Twenty-nine people with Parkinson’s Disease participated in nine focus groups. Studies II-III
Holding onto Electrons in Alkali Metal Halide Clusters: Decreasing Polarizability with Increasing Coordination
The connection between the electronic polarizability and the decrease of the system size from macroscopic solid to nanoscale clusters has been addressed in a combined experimental and model-calculation study. A beam of free neutral potassium chloride clusters has been probed using synchrotron-radiation-based photoelectron spectroscopy. The introduction of "effective" polarizability for chlorine, l

Access to research inputs: open science versus the entrepreneurial university
The viability of modern open science norms and practices depends on public disclosure of new knowledge, methods, and materials. However, increasing industry funding of research can restrict the dissemination of results and materials. We show, through a survey sample of 837 German scientists in life sciences, natural sciences, engineering, and social sciences, that scientists who receive industry f

Clinical application of stem cell therapy in Parkinson's disease
Cell replacement therapies in Parkinson's disease (PD) aim to provide long-lasting relief of patients' symptoms. Previous clinical trials using transplantation of human fetal ventral mesencephalic (hfVM) tissue in the striata of PD patients have provided proof-of-principle that such grafts can restore striatal dopaminergic (DA-ergic) function. The transplants survive, reinnervate the striatum, and
A novel personal cooling system (PCS) incorporated with phase change materials (PCMs) and ventilation fans: An investigation on its cooling efficiency
Personal cooling systems (PCS) have been developed to mitigate the impact of severe heat stress for humans working in hot environments. It is still a great challenge to develop PCSs that are portable, inexpensive, and effective. We studied the performance of a new hybrid PCS incorporating both ventilation fans and phase change materials (PCMs). The cooling efficiency of the newly developed PCS was
Suppressing memory T cell activation induces islet allograft tolerance in alloantigen-primed mice
P>Memory T cells are known to play a key role in prevention of allograft tolerance in alloantigen-primed mice. Here, we used an adoptively transferred memory T cell model and an alloantigen-primed model to evaluate the abilities of different combinations of monoclonal antibodies (mAb) to block key signaling pathways involved in activation of effector and memory T cells. In the adoptively transferr
Informal Employment and the Role of Regional Governance
The aim of this paper is to provide an explanation to why the degree of informal employment may vary substantially between different regions within a country. In Brazil, 45% of workers in the urban labor force are employed informally. The degree of informal employment, however, varies substantially across regions, with some cities having 20% and others having 80% or more of their labor force in th
Technical evaluation of different motion-monitoring systems for respiratory gating in radiation therapy
The purpose of this work was to evaluate three motion-monitoring systems: Sentinel (TM), Catalyst (TM) (both C-RAD) and Real-time Position Management (RPM (TM)) system (Varian Medical Systems Inc) for respiratory gating in radiotherapy. To measure the systems. latency, an in-house built circuit with a microcontroller operating a piston was used. The trigger pulse was sent from the gating systems t
Sialic Acid-Imprinted Fluorescent Core-Shell Particles for Selective Labeling of Cell Surface Glycans
The expression of cell surface glycans terminating with sialic acid (SA) residues has been found to correlate with various disease states there among cancer. We here report a novel strategy for specific fluorescence labeling of such motifs. This is based on sialic acid-imprinted core shell nanopartides equipped with nitrobenzoxadiazole (NBD) fluorescent reporter groups allowing environmentally sen
INVESTIGATION OF PARTIAL VOLUME EFFECT IN DIFFERENT PET/CT SYSTEMS: A COMPARISON OF RESULTS USING THE MADEIRA PHANTOM AND THE NEMA NU-2 2001 PHANTOM.
Positron emission tomography combined with computed tomography (PET/CT) is a quantitative technique used for diagnosing various diseases and for monitoring treatment response for different types of tumours. However, the accuracy of the data is limited by the spatial resolution of the system. In addition, the so-called partial volume effect (PVE) causes a blurring of image structures, which in turn
Tamm-Horsfall protein gene is associated with distal tubular dysfunction in patients with type 1 diabetes
Objective. The first changes in the diabetic kidney are glycogen deposits in the epithelial cells of the thick ascending limb of Henle, which leads to decreased production of Tamm-Horsfall protein (THP). The production of THP is also influenced by nitric oxide (NO). The aims of this study were to investigate whether low excretion of THP, a sign of distal tubular dysfunction, in patients with type
Glial Progenitor-Like Phenotype in Low-Grade Glioma and Enhanced CD133-Expression and Neuronal Lineage Differentiation Potential in High-Grade Glioma
Background: While neurosphere-as well as xenograft tumor-initiating cells have been identified in gliomas, the resemblance between glioma cells and neural stem/progenitor cells as well as the prognostic value of stem/progenitor cell marker expression in glioma are poorly clarified. Methodology/Principal Findings: Viable glioma cells were characterized for surface marker expression along the glial
Pragmatic estimation of a spatio-temporal air quality model with irregular monitoring data
Statistical analyses of health effects of air pollution have increasingly used GIS-based covariates for prediction of ambient air quality in "land use" regression models. More recently these spatial regression models have accounted for spatial correlation structure in combining monitoring data with land use covariates. We present a flexible spatio-temporal modeling framework and pragmatic, multi-s
