The interaction of protein S with membranes and subsequent combination with complement C4b-binding protein (C4BP) was studied. Protein S interacted with phospholipid vesicles in a calcium-dependent manner typical of other vitamin K-dependent proteins. Association of C4BP with protein S showed no apparent selectivity for membrane-bound or solution phase protein S. When bound to the membrane, the pr
Introduction: Primary health care centers (PHCCs) in Sweden are struggling to maintain a balance between increasing demands of service and supervision and learning activities for a growing number of students. We sought a deeper understanding of primary care physicians and managers behavioral intention towards supervising, and their perceptions of the structural preconditions and support needed.Met
Examining the archaeological material of the modern period, over a period of the last 500 years, this open access book presents a series of case studies that challenges the fallacy of Nordic egalitarianism. The widening gap between rich and poor Western countries is now a well-known phenomenon and, while Scandinavia has often been hailed as one of the regions where inequality has been the lowest,
Organic pollutants in aquatic environments pose a threat to ecosystems and human health, a challenge that requires urgent resolution. This urgent threat highlights the need for the development of efficient technologies for pollutant detection and degradation in environmental protection. This study presents the successful fabrication of a composite nanomaterial consisting of Ag nanoparticle-decorat
Aducanumab, a human IgG1 antibody with plaque-clearing effects and modest clinical benefit, binds selectively to aggregated Aβ via the N-terminal region. Yet, the molecular details of how the antibody engages Aβ1-42 fibrils remain unresolved. Using magic-angle spinning NMR, we show that binding of aducanumab preserves the overall architecture of the Aβ1-42 fibril core while inducing significant st
Undersköterskeyrket är den största yrkesgruppen i Sverige och många arbetar i hemtjänsten med dåliga arbetsvillkor och begränsade resurser. Situationen kan beskrivas som en omsorgskris. En sociologiskt relevant frågeställning är hur hemtjänst- personalen upplever denna verklighet och om - och isåfall hur - de gör motstånd. Syftet med studien är alltså att med utgångspunkt i hemtjänstarbetares erfa
Objective To investigate the relationship between active commuting and atherosclerosis in middle age using state-of-the-art coronary CT angiography (CCTA). Methods This cross-sectional study used data from the Swedish CArdioPulmonary bioImage Study (SCAPIS) and included 23 722 randomly recruited individuals aged 50–64 years from six different regions in Sweden. The exposure was commuting mode, ass
Questions: Earth observation is an important tool in biological monitoring. Previous studies have shown that variation in grassland canopy reflectance can explain gradients in plant community composition. However, there is a need for methods that allow the interpretation of the overall spectral signal of complex grassland vegetation in terms of existing knowledge about individual species' habitat
Flödescytometri som verktyg i dricksvattenproduktionens kvalitetssäkrande arbete Dricksvattenproducenter har flera metoder för att undersöka och kontrollera vattnets kvalitet. Den mikrobiella kvaliteten kan ta allt ifrån 18h till sju dygn att fastställa. Flödescytometri är en metod som har föreslagits som ett potentiellt alternativ eller tillägg till dessa metoder, och som erbjuder korta analystiQuality assurance is crucial for producers of drinking water, and several steps are taken to ensure a safe and aesthetically acceptable drinking water. Monitoring the microbiological quality of drinking water, both finished and within the drinking water treatment plants, is done through cultivation-based techniques. These techniques can take up several days before results can be seen, and quicker
Neophobia, or aversion to novelty, is important for adaptability and survival as it influences the ways in which animals navigate risk and interact with their environments. Across individuals, species and other taxonomic levels, neophobia is known to vary considerably, but our understanding of the wider ecological drivers of neophobia is hampered by a lack of comparative multispecies studies using
This doctoral thesis investigates mediaeval earthenware production, distribution and consumption based on material from Lund, Sweden, moving beyond simple technological shifts to explore the interplay of material factors, social practices, and economic influences. It presents a typology of hard greyware, redware and glazed redware, as well as the chemical analysis of circa 400 samples. The study a
The purpose of this thesis is to examine how an administrative court should address deficiencies in the investigation of administrative cases when an administrative authority has failed to fulfil its duty to investigate. Against this background, the study explores the courses of action available to the court and how these relate to the function and purpose of administrative procedure. Administrat
Amelogenin self-assembly is a critical step in enamel matrix organization, supporting the spatial confinement of transient ACP and orchestrating hydroxyapatite nucleation and ordered growth. Studies have demonstrated that amelogenin self-assembles into nanoribbons by forming an amyloid-like structure that matches the cross-β pattern observed in the developing enamel matrix. However, molecular dete
Introduction: The European corn borer (ECB), Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), is a major pest insect in maize. New cultivars and climate change have allowed range expansion of the crop northwards in Europe, and a similar range expansion of associated pests has been predicted. ECB exists as two distinct pheromone strains using different blends of (E)-11-tetradecenyl acetate and
Nitrogenase is the only enzyme that can cleave the triple bond in N2, making nitrogen available to organisms. The detailed mechanism of this enzyme is currently not known, and computational studies are complicated by the fact that different density functional theory (DFT) methods give very different energetic results for calculations involving nitrogenase models. Recently, we designed a [Fe(SH)4H]
Fibril-reinforced poroviscoelastic material models are considered state-of-the-art in modeling articular cartilage biomechanics. Yet, cartilage material parameters are often based on bovine tissue properties in computational knee joint models, although bovine properties are distinctly different from those of humans. Thus, we aimed to investigate how cartilage mechanical responses are affected in t
