The Aβ42/Aβ40 ratio in the cerebrospinal fluid (CSF) and the concentrations of neurofilament light (NfL) and total tau (t-tau) are changed in the early stages of Alzheimer’s disease (AD)1, but their neurobiological correlates are not entirely understood. Here, we used 5xFAD transgenic mice to investigate the associations between these CSF biomarkers and measures of cerebral Aβ, including Aβ42/Aβ40

Aims. Chronotropic incompetence and impaired heart rate (HR) recovery are related to mortality. Guidelines lack specific reference values for HR recovery. We defined normal values and studied blunted HR response and recovery and mortality risk. Methods and results. We included 9917 subjects (45% females) aged 18–85 years who performed a cycle exercise test. We defined normal values for peak HR, HR

The traditional Talmian binary typology of satellite-framed vs. verb-framed languages has proven to be insufficient for showing the diversity across the world’s languages. One approach within post-Talmian motion typology follows Holistic Spatial Semantics, which has been applied to languages like Swedish, French, Thai and Telugu, but not to Slavic languages. This motivates the present research. We

Background: Myocardial fibrosis, expressed as late gadolinium enhancement (LGE) on cardiac magnetic resonance imaging (CMR), is an important risk factor for malignant cardiac events in hypertrophic cardiomyopathy (HCM). However, CMR is not easily available, expensive, also needing intravenous access and contrast. Objective: To determine if derived vectorcardiographic spatial QRS-T angles, an aspec

Metastatic breast cancer (MBC) is generally considered an incurable disease and even though new treatments are available, the median survival is approximately three years. The introduction of immune therapies for MBC highlights the importance of the immune system in cancer progression and treatment. CD163+ anti-inflammatory myeloid cells, including tumor associated macrophages (TAMs), are known to

Although it is widely recognized that leadership concerns organizing future actions and mobilizing organizational actors to pursue them, our understanding of how this is accomplished in situated work interactions is relatively limited. Recent ethnographic studies have focused on leadership work resulting in the emergence of direction.

Att arter har begränsade geografiska utbredningsområden beror ofta på en begränsad förmåga att anpassa sig till de miljöförhållanden som råder utanför arternas utbredningsgränser. På grund av pågående klimatförändringar kan dock de miljöförhållanden som råder inom arters nuvarande utbredningsområden komma att ändras inom den närmaste framtiden. För att undgå utrotning kommer därför många populatioThe fact that species have limited ranges is often due to a limited ability to adapt to the environmental conditions that occur outside their geographic ranges. However, due to ongoing climate change, the environmental conditions within species’ geographic ranges may change in the near-future. To avoid extinction, many populations therefore need to migrate to new areas and/or adapt to the new cond

BACKGROUND: The efficacy of corticosteroids for treating acute vestibular neuritis, or acute unilateral vestibulopathy (AUVP), remains controversial.OBJECTIVE: This study aimed to evaluate whether corticosteroids improve vestibular function and reduce symptoms in both acute and chronic phases of AUVP.METHODS: This randomized, placebo-controlled, double-blind trial included patients with AUVP (ages

We report on neutron scattering measurements on the vortex lattice of the noncentrosymmetric superconductor BiPd. We observe the existence of the intermediate mixed state, a region where Meissner and vortex lattice phases coexist, which is a feature of low type-II superconductors. Following this, we obtain an estimate of the value of using the extended London model. Finally, we find that the tempe

BACKGROUND: Perfluoroalkyl substances (PFAS) are stable chemicals used in various applications. PFAS exposure has been associated with lower birth weight and immunological effects in children, and limited evidence further suggests adverse neurodevelopmental effects. Previous studies show that PFAS cross the placental barrier during pregnancy leading to prenatal exposure of the fetus. Research on t

ABSTRACTObjectivesAn emerging body of research reveals a heightened risk of gambling problems among elite athletes, particularly among males, but these studies often suffer from small sample sizes and lack diverse representation across sports and groups. This study aimed to investigate gambling problems and their correlates among elite male and female ice hockey players in Sweden’s top leagues.Met

The demand for cost- and time-effective and customizable components for High Vacuum (HV) and Ultra-High Vacuum (UHV) systems has prompted exploration into the application of 3D-printing technology. This study investigates the viability of utilizing 3D-printed plastics in UHV environments by evaluating their outgassing properties. An extensive evaluation of 3D-printing materials was carried out, hi

Toxicity pathways of engineered carbon nanomaterials, which have many and diverse industrial applications, include oxidative stress primarily due to the generation of reactive oxygen species (ROS). This study on 13 carbon black, 6 Graphene nanoplatelets (GNP), and 3 nanodiamond materials identified physicochemical properties driving their ROS production. ROS production was cross-validated using di

This paper examines the influence of artificial intelligence (AI) on recent operatic practice, exploring its potential to affect the development of the genre from the artist’s perspective. While opera has historically evolved in tandem with technological advancements, the integration of AI raises important questions about its function within the operatic toolbox and its relation to the genre’s cor

Let f be a holomorphic self-map of the unit disc. We show that if log(1 − | f (z)|) is integrable on a sub-arc of the unit circle, I , then the set of points where the function f has finite Carathéodory angular derivative on I is a countable union of Beurling–Carleson sets of finite entropy. Conversely, given a countable union of Beurling–Carleson sets, E , we construct a holomorphic self-map of t

It was not a given that petrol-powered cars would come to dominate the world. In fact, back in 1900, just 22% of cars produced in the US were powered by gasoline (also known as petrol, benzine or various other names). The rest split between electric and steam cars.
