Cushioned lipid bilayers are structures consisting of a lipid bilayer supported on a solid substrate with an intervening layer of soft material. They offer possibilities for studying the behavior and interactions of biological membranes more accurately under physiological conditions. In this work, we continue our studies of cushion formation induced by histatin 5 (24Hst5), focusing on the effect o
This literature review presents a summary of recent research about PM-less machines for electrical vehicles. Recently, IPM machines has proven to be very popular among electrical vehicle manufacturers. However, the neodymium permanent magnets being used are expensive and have a risk of rocketing the production cost of a machine if the price increases more. With this in mind, five PM-less machine t
Oligomeric species arising during the aggregation of α-synuclein are implicated as a major source of toxicity in Parkinson’s disease, and thus a major potential drug target. However, both their mechanism of formation and role in aggregation are largely unresolved. Here we show that, at physiological pH and in the absence of lipid membranes, α-synuclein aggregates form by secondary nucleation,
Functional amyloids formed by the protein FapC in Pseudomonas bacteria are key structural components of Pseudomonas biofilms, which mediate chronic infections and also contribute to antimicrobial resistance. Here, we combine kinetic experiments with mechanistic modelling to probe the role of surfaces in FapC functional amyloid formation. We find that nucleation of new fibrils is predominantly hete
BackgroundHospitalization indicates the presence of severe disease and constitutes a leading cost in health care. We aimed to prospectively assess if prevalent diabetes mellitus contributes to excess all-cause and cause-specific hospital admissions and mortality at the population level.MethodsWe used a Swedish prospective population-based cohort, including 25,642 individuals of whom 4.2% had preva
Objective: To investigate the feasibility of using neutron tomography to gain new knowledge of human articular cartilage degeneration in osteoarthritis (OA). Different sample preparation techniques were evaluated to identify maximum intra-tissue contrast. Design: Human articular cartilage samples from 14 deceased donors (18–75 years, 9 males, 5 females) and 4 patients undergoing total knee replace
Introduction: Information about autonomic nervous system (ANS) activity may offer insights about atrial fibrillation (AF) progression and support personalized AF treatment but is not easily accessible from the ECG. In this study, we propose a new approach for ECG-based assessment of respiratory modulation in atrioventricular (AV) nodal refractory period and conduction delay. Methods: A 1-dimension
Background: Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease characterized by chronic bronchitis, emphysema and vascular remodelling. The disease is associated with hypoxia, inflammation and oxidative stress. Lung fibroblasts are important cells in remodelling processes in COPD, as main producers of extracellular matrix proteins but also in synthesis of growth factors and in
BACKGROUND: Women with a history of adverse pregnancy outcomes have a higher risk of coronary heart disease. Emerging evidence suggests that women with a history of preeclampsia have a different pattern of overall coronary atherosclerosis and that they at the time of myocardial infarction (MI) more frequently present with ST-segment elevation MI (STEMI) compared to women with no such history.OBJEC
Purpose: Paleolithic Diet Fraction (PDF) estimates how large a portion of the absolute dietary intake stems from food groups included in the Paleolithic diet. In randomized controlled trials higher PDFs have been associated with healthier levels of cardiometabolic risk markers. Our aim was to build upon these findings by examining associations between PDF and mortality and incidence of cardiometab
Making music with digital tools might be considered common knowledge in music education. However, there are vast numbers of music teachers who feel insecure when it comes to actually using it as a prominent tool for music making in their classrooms. The objective of this workshop is to show how students of different ages together with their music teachers create, produce and perform music by EDI.
To make glomerular filtration rate (GFR) estimating equations applicable across populations with different creatinine generation by using rescaled serum creatinine (sCr/Q) where sCr represents the individual creatinine level and Q the average creatinine value in healthy persons of the same population. GFR measurements (mGFR, plasma clearance of 51Cr-EDTA) were conducted in 964 adult Black European
Understanding microbes in nature requires consideration of their microenvironment. Here, we present a protocol for quantifying biomass and nutrient degradation of bacterial and fungal cultures (Pseudomonas putida and Coprinopsis cinerea, respectively) in microfluidics. We describe steps for mask design and fabrication, master printing, polydimethylsiloxane chip fabrication, and chip inoculation an
AimTo explore perceptions of annual surveillance with magnetic resonance imaging and perceptions of care during the examination among women with a hereditary risk of breast cancer.DesignPhenomenography.MethodsFourteen face-to-face interviews using a semi-structured interview guide were conducted among women undergoing surveillance in the southern region of Sweden. A seven-step phenomenographic ana
Objectives: Experimental and small human studies have indicated that high total adiponectin levels have beneficial cardiometabolic effects. In contrast, however, high total adiponectin levels are also associated with higher all-cause and cardiovascular mortality in thoroughly adjusted epidemiological studies. To gain further insight into these seemingly contradictory results, we report results on
