Formation of amyloid-β (Aβ) fibrils is a central pathogenic feature of Alzheimer's disease. Cell-secreted extracellular vesicles (EVs) have been suggested as disease modulators, although their exact roles and relations to Aβ pathology remain unclear. We combined kinetics assays and biophysical analyses to explore how small (<220 nm) EVs from neuronal and non-neuronal human cell lines affected the

Artikeln argumenterar för en förnyad relevansen för tidsgeografi iturism i ljuset av mobil teknikanvändning och allestädes närvarandedigital uppkoppling. Uppsatsen föreslår begreppet fygitalitet för attförstå hur digital teknik används i det fysiska rummet, ochhur samspelet mellan det fysiska och det digitala omformasi turisters projekt, rutter, kopplingar och begränsningar. Det teoretiskabidragetThe paper argues for the renewed relevance of time geography in tourism in light of the use of mobile technologies and ubiquitous connectivity. The paper proposes the concept of phygitality to understand how digital technologies are used in physical space, and how the interaction between the physical and the digital reconfigures tourists’ projects, paths, bundles, and constraints. The theoretical

In this article some initial results from the projects "Bronsildems deglar" (en. "Bronze Age melting crucibles") and "Deglarna frin Bokenäs" (en. "The crucibles from Bokenäs") are presented. The aim of the projects is to expand our knowledge of the production, use and discard of technical ceramics in south Sweden using laboratory analysis.

This research tests whether self-labelling with a derogatory or reclaimed label is perceived as an act of reclamation. A pilot study (N = 102) identified English terms used to label lesbian women and gay men. The main study (N = 276) used a between-groups vignette design in which participants read about a woman/man self-labelling with a descriptive (lesbian/gay), reclaimed (queer), or derogatory g

This paper focuses on Bronze Age melting crucibles in southern Scandinavia. The shape and purpose of the crucibles have long been known, but the process of making one has not been studied thoroughly. The crucibles have in some cases been reconstructed in order to replicate the casting process or the finished product, but have rarely been the main subject of research. In this paper crucibles found

Eutrophication and brownification are ongoing environmental problems affecting aquatic ecosystems. Due to anthropogenic changes, increasing amounts of organic and inorganic compounds are entering aquatic systems from surrounding catchment areas, increasing both nutrients, total organic carbon (TOC), and water color with societal, as well as ecological consequences. Several studies have focused on

Patients with Wilms tumor (WT) in general have excellent survival, but the prognosis of patients belonging to the subgroup of WT with diffuse anaplasia (DA) is poor due to frequent resistance to chemotherapy. We hypothesized that DA WT cells might undergo changes, such as acquiring a persistent tolerance to DNA damage and copy number aberrations (CNAs), which could eventually lead to their resista

Background: Tuberculosis (TB) disease has been associated with pregnancy complications. However, the potential impact of TB infection (TBI) on pregnancy outcome is unknown. To investigate this, we conducted a register-based study in immigrant women screened with QuantiFERON assays for TBI in antenatal care in Sweden. Methods: Women with history of immigration from TB-endemic countries were eligibl

Background: In Sweden, information on seroprevalence of tick-borne encephalitis virus (TBEV) in the population, including vaccination coverage and infection, is scattered. This is largely due to the absence of a national tick-borne encephalitis (TBE) vaccination registry, scarcity of previous serological studies and use of serological methods not distinguishing between antibodies induced by vaccin

Background: There is little agreement on clinically useful criteria for identifying real-world responders to biologic treatments for asthma. Objective: To investigate the impact of pre-biologic impairment on meeting domain-specific biologic responder definitions in adults with severe asthma. Methods: This was a longitudinal, cohort study across 22 countries participating in the International Sever

Cooperative transport allows for the transportation of items too large for the capacity of a single individual. Beyond humans, it is regularly employed by ants and social spiders where two or more individuals, with more or less coordinated movements, transport food to a known destination. In contrast to this, pairs of male and female dung beetles successfully transport brood balls to a location un

Leveraging the potential of machine learning and recognizing the broad applications of binary classification, it becomes essential to develop platforms that are not only powerful but also transparent, interpretable, and user friendly. We introduce alphaML, a user-friendly platform that provides clear, legible, explainable, transparent, and elucidative (CLETE) binary classification models with comp

Diabetic muscle atrophy is an inflammation-related complication of type-2 diabetes mellitus (T2DM). Even though regular exercise prevents further deterioration of atrophic status, there is no effective mediator available for treatment and the underlying cellular mechanisms are less explored. In this study, we investigated the therapeutic potential of MCC950, a specific, small-molecule inhibitor of

Poor self-rated health (SRH) is associated with incident arterial cardiovascular disease in both sexes. Studies on the association between SRH and incident venous thromboembolism (VTE) show divergent results in women and no association in men. This study focuses on the association between change in SRH and incident VTE in a cohort of 11,558 men and 6682 women who underwent a baseline examination a

Background: Creativity is a multifaceted, complex, activity, and as such is an overarching function of the brain rather than being confined to a specific structure or region. Alzheimer's disease effects several cognitive domains involved in the creative process of producing art. Objective: We analyze the art of a well-known Swedish visual artist who suffered from Alzheimer's disease to determine i

Single bicycle crashes, i.e., falls and impacts not involving a collision with another road user, are a significantly underestimated road safety problem. The motions and behaviours of falling people, or fall kinematics, are often investigated in the injury biomechanics research field. Understanding the mechanics of a fall can help researchers develop better protective gear and safety measures to r

Abstract in GermanIn Die Soziallehren der christlichen Kirchen und Gruppen stellt Ernst Troeltsch ein riesiges Forschungsprogramm auf, das an der Schnittstelle von Soziologie und Theologie liegt. In Auseinandersetzung mit materialistischen und idealistischen Ansätzen erforscht er das Christentum als „Praxis“, in der theologische Ideale auf soziologische Realitäten und soziologische Realitäten auf

Abstract in GermanSecularization: An Analysis at Three Levels lässt sich als Synthese von Karel Dobbelaeres Arbeiten lesen. Er definiert Säkularisierung darin als einen Prozess, durch den Religion in Gesellschaften der Moderne mehr und mehr an Bedeutung verliert. Der Grundgedanke Dobbelaeres lautet dabei, dass Säkularisierung nach makro-, meso- und mikrosoziologischer Ebene zu differenzieren ist.
