Stable population-based incidence of acute type A and B aortic dissection

Background. Aortic dissection (AD) and abdominal aortic aneurysm (AAA) share the same risk factors. Whereas the incidence of AAA is falling, it is unclear whether population-based incidences of acute type A and B AD have changed. The aim of this study was to investigate incidences of AD subtypes over time. Methods. Citizens in the municipality of Malmö, Sweden, diagnosed with AD in 2000–2004 and 2

Trembling in Fear and Passion : Kierkegaard's Leap of Faith as a Source of the Sublime

This essay investigates how Søren Kierkegaard’s leap of faith can be viewed as a sublime esthetic experience along the lines of the theories of Longinus and Edmund Burke. In Kierkegaard leaps of faith incorporate feelings of terror and passion. Grounded in notions of eternity and truth, they create occasions for particular kinds of sublime experiences. To Kierkegaard the leap of faith is the step

Imprint of the galactic acceleration scale on globular cluster systems

We report that the density profiles of globular cluster (GC) systems in a sample of 17 early-Type galaxies (ETGs) show breaks at the radii where the gravitational acceleration exerted by the stars equals the galactic acceleration scale a0 known from the radial acceleration relation or the modified Newtonian dynamics (MOND). The match with the other characteristic radii in the galaxy is not that cl

An exploratory study of verbal interaction between children with different profiles of DLD and their classroom teachers in educational dialogues

Children with a history of developmental language disorder (DLD) entering school are a challenge for classroom teachers. Teachers are often not very familiar with DLD, and language difficulties in school age children are often not obvious in context-supported everyday language. However, their language is still vulnerable. The teachers’ way of talking with four children with DLD, two with predomina

Vertical III-V Nanowire MOSFETs

Vertical III-V nanowire MOSFETs are interesting candidates for future digital and analog applications. High electron velocity III-V materials allow fabrication of low power and high frequency MOSFETs. Vertical vapor-liquid-solid growth enables fabrication of axial and radial heterostructure nanowires. This enables fabrication of novel structures where the band-gap can be engineered in the electron

Loss of cyclin-dependent kinase 1 impairs bone formation, but does not affect the bone-anabolic effects of parathyroid hormone

Bone mass is maintained by a balance between osteoblast-mediated bone formation and osteoclast-mediated bone resorption. Although recent genetic studies have uncovered various mechanisms that regulate osteoblast differentiation, the molecular basis of osteoblast proliferation remains unclear. Here, using an osteoblast-specific loss-of-function mouse model, we demonstrate that cyclin-dependent kina

Priors and Posteriors in Bayesian Timing of Divergence Analyses : The Age of Butterflies Revisited

The need for robust estimates of times of divergence is essential for downstream analyses, yet assessing this robustness is still rare. We generated a time-calibrated genus-level phylogeny of butterflies (Papilionoidea), including 994 taxa, up to 10 gene fragments and an unprecedented set of 12 fossils and 10 host-plant node calibration points. We compared marginal priors and posterior distributio

Engaging with the general public on critical raw materials through the medium of electronics repair workshops.

The issue of Critical Raw Materials (CRMs) and potential interruptions to their supply andavailability due to concerns such as shortages, trade restrictions or geopolitical considerations are topicsthat are relatively unknown to the general public. Education and the dissemination of this informationamongst the general public has been promoted as a key factor in addressing this and enabling thetran

Non-invasive ultrasound measurements of vascular impedance : Rekindling an old in-house concept on in vivo measurements

Trots dess introduktion under början av 1950-talet används vaskulär impedans ännu inte i klinisk omfattning för att förutsäga tidiga stadier av hjärt-kärlsjukdomar. Definierad som förhållandet mellan blodtryck och blodflöde beskriver vaskulär impedans motståndet mot blodflödet i det vaskulära systemet.Under detta avhandlingsprojekt uppskattades den lokala pulsvåghastigheten (PWV) och vaskulära impDespite its introduction in the early 1950´s, vascular impedance has yet to be applied in clinical use to predict early stages of cardiovascular disease (CVD). It is defined as the ratio between blood pressure and flow and describes the opposition to blood flow within the cardiovascular system.During this thesis project, local pulse wave velocity (PWV) and vascular impedance was estimated from in

Identification of transcriptional and metabolic programs related to mammalian cell size

SummaryBackground Regulation of cell size requires coordination of growth and proliferation. Conditional loss of cyclin-dependent kinase 1 in mice permits hepatocyte growth without cell division, allowing us to study cell size in vivo using transcriptomics and metabolomics. Results Larger cells displayed increased expression of cytoskeletal genes but unexpectedly repressed expression of many genes

Detection and possible functional influence of antibodies directed againt the pancreatic islet cell surface.

Antibodies directed towards determinants on the surface of rat islet cells can be detected qualitatively by the indirect immunofluorescence or quantitatively by a specific radioassay for IgG. Antibodies are found in insulin-dependent diabetics or in rabbits immunized with islet cells. Such antibodies may affect the B-cell function as indicated by the inhibition of incorporation of radioactive leuc
