The aim of this study was to investigate the correlations between epidemiological indices (objective) and self-perceived oral health (subjective) in adolescents at school level, and to study gender differences in epidemiological indices and in self-perceived oral health. The study comprised two sets of data from Skaraborg County, Sweden: 1. Self-reported questionnaires answered by adolescents at a
Detailed particle size distribution of elemental constituents have been determined in the St. Louis aerosol by sampling with cascade impactors for particles >0.25 μm aerodynamic diameter and by analyzing using proton-induced X-ray emission, PIXE, for S, Cl, K, Ca, Ti, Mn, Fe, Zn, Br, and Pb. Two rooftop sites were selected for intensive sampling in industrial and residential locations in St. Louis
Popular Abstract in Swedish Streptococcus pyogenes (GAS) är en viktig sjukdomsframkallande bakterie som orsakar alltifrån lindriga infektioner som halsfluss (tonsillit) och svinkoppar (impetigo) till livshotande djupa infektioner som nekrotiserande fasceit eller ”Toxic shock syndrom”. På grund av det snabba sjukdomsförloppet i de livshotande infektionerna har streptokockerna fått beteckningen ”mörA distinguishing feature of Streptococcus pyogenes (GAS) is their ability to resist phagocytosis in whole human blood in the absence of type-specific antibodies, a property that is dependent on the expression of the surface associated M proteins. A common characteristic of M proteins is their interaction with a variety of host proteins including the complement regulatory protein factor H (FH) and
Popular Abstract in Undetermined Denne afhandling præsenterer en ny udlæsnings metode udviklet til cantileverbaserede sensorer. Cantilevere er tynde vipper, der er fastgjorte i den ene ende, og som igennem de seneste ti °ar har vist sig at være en interessant ny type bio/kemisk sensor. Den specifikke genkendelse af et kemikalie viser sig ved at cantileveren bøjer som følge af det skabte overfladesThis thesis presents a novel read-out method developed for cantilever-based sensors. Cantilevers are thin beams clamped at one end and during the last 10 years they have emerged as an interesting new type of bio/chemical sensor. The specific recognition of a chemical manifests itself as a bending of the cantilever from the generated surface stress. Conventionally the read-out used for this type of
ABSTRACT Author: Rowena E. Nystrand Title: “It’s a case of fitting into the picture, otherwise you’ve failed …” A qualitative study of men's experience of becoming an involuntary father (translated title) Supervisor: Anders Östnäs Assessor: Håkan Jönson The background to this paper lies in a media interest in the problems of unwilling fathers but with very little research having been done i
Examensarbetet besvarar frågan om överföringar av asylsökande till Georgien som ännu inte fått sina asylskäl utförligt utredda skulle utsätta dem för en verklig risk för omänsklig eller förnedrande behandling och därmed vara oförenliga med Europakonventionens artikel 3. Asylrätten bygger på bedömningar av individuella asylskäl. I examensarbetet studeras därför problem i Georgien som är generella nThis graduate thesis examines if readmitting asylum seekers from EU member states to Georgia without first thoroughly assessing their claims would be illegal on the grounds that it would expose them to a real risk of ill-treatment contrary to Article 3 of the European Convention on Human Rights. The basis of asylum law is protection based on individual grounds. This graduate thesis therefore studi
Introduction: Physical inactivity, low aerobic fitness and obesity are all associated with an increased risk of a wide range of diseases in adults. Promotion of physical activity, improvement of aerobic fitness and regulation of body weight in children may be of importance, as low physical activity, low aerobic fitness and obesity early in life have been known to track into adulthood. However, rel
The objective of this study was to evaluate the concentrations of nutrients in stumps and coarse roots in Norway spruce, Scots pine and silver birch in Sweden, Finland and Denmark, and to assess how nutrient concentrations vary with site characteristics, stand age and root size. Concentrations of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sodium (Na) in spruce, p
In November 2011, the Third European Consensus Conference on Diagnosis and Treatment of Germ-Cell Cancer (GCC) was held in Berlin, Germany. This third conference followed similar meetings in 2003 (Essen, Germany) and 2006 (Amsterdam, The Netherlands) [Schmoll H-J, Souchon R, Krege S et al. European consensus on diagnosis and treatment of germ-cell cancer: a report of the European Germ-Cell Cancer
Background: Procedures documented by general practitioners in primary care have not been studied in relation to procedure coding systems. We aimed to describe procedures documented by Swedish general practitioners in electronic patient records and to compare them to the Swedish Classification of Health Interventions (KVA) and SNOMED CT. Methods: Procedures in 200 record entries were identified, co
Sexually transmitted diseases (STDs) have been shown to increase the Costs Of multiple mating and therefore favor relatively monogamous mating strategies. We examine another way in which STDs can influence mating systems in species in which female choice is important. Because more popular males are more likely to become infected, STDs can counteract any selective pressure that generates strong mat
Identifying the genes that underlie phenotypic variation in natural populations, and assessing the consequences of polymorphisms at these loci for individual fitness are major objectives in evolutionary biology. Yet, with the exception of a few success stories, little progress has been made, and our understanding of the link between genotype and phenotype is still in its infancy. For example, alth
Processes of rapid radiation among unicellular eukaryotes are much less studied than among multicellular organisms. We have investigated a lineage of cold-water microeukaryotes (protists) that appear to have diverged recently. This lineage stands in stark contrast to known examples of phylogenetically closely related protists, in which genetic difference is typically larger than morphological diff
G-protein-regulated inward-rectifier potassium channel 2 (GIRK2) is reported to be expressed only within certain dopamine neurons of the substantia nigra (SN), although very limited data are available in humans. We examined the localization of GIRK2 in the SN and adjacent ventral tegmental area (VTA) of humans and mice by using either neuromelanin pigment or immunolabeling with tyrosine hydroxylas
Background Various genome-wide association studies (GWAS) have been done in ischaemic stroke, identifying a few loci associated with the disease, but sample sizes have been 3500 cases or less. We established the METASTROKE collaboration with the aim of validating associations from previous GWAS and identifying novel genetic associations through meta-analysis of GWAS datasets for ischaemic stroke a
In this work, influence of hydrogen and temperature on the fracture toughness parameters of unirradiated, cold worked and stress relieved (CWSR) Zr-2.5Nb pressure tube alloys used in Indian Pressurized Heavy Water Reactor is reported. The fracture toughness tests were carried out using 17 mm width curved compact tension specimens machined from gaseously hydrogen charged tube-sections. Metallograph
Background The well-being of patients with Parkinson's disease may be improved by pharmaceutical care in community pharmacies. Objective To investigate the effects of standardised pharmaceutical care on health outcomes and quality of drug treatment in patients with Parkinson's disease. Setting Community pharmacies in Germany. Method An open-label, multicentre, longitudinal, parallel-group study wa
Rate control of atrial fibrillation (AF) is a main treatment modality. However, data are scarce on the relative efficacy of calcium channel blockers and 13 blockers or between drugs within each class. The purpose of the present study was to compare the effect of 4 rate-reducing, once-daily drug regimens on the ventricular heart rate and arrhythmia-related symptoms in patients with permanent AF. We
