The Role of RB1 and Secondary Genomic Changes in the Development of Spindle Cell and Pleomorphic Lipomas

Spindle cell lipomas (SCL) and pleomorphic lipomas (PL) are today considered a single tumor entity (SCLPL). Atypical SCLPL, in contrast, represents a recently recognized related but distinct entity. Here we explored the correlation between genomic features and morphological aspects of SCLPL and atypical SCLPL and the role of the RB1 gene in tumor development. Seventy-one samples from 68 patients w

Perceptual discrepancies in the experience and reporting of violence against children are more pronounced among social workers compared to laypeople

When violence against a child is reported to authorities, it is crucial that its severity is communicated effectively and evaluated accurately by professionals. This study, conducted in two phases, investigated perceptual differences in calibration and accuracy regarding psychological and physical violence against children among parents, social workers, and laypeople. In Phase 1, parents who had w

What can mission-oriented innovation policy learn from China?

The concept of a mission-oriented innovation policy has been discussed for several years now, with definitions and conceptual understanding gradually emerging. Although focused on grand societal challenges, i.e. on a particular type of problem that has been receiving attention only in the last couple of years, the discussion and the design of mission-oriented innovation policy can still draw on pa

Medial temporal lobe Tau-Neurodegeneration mismatch from MRI and plasma biomarkers identifies vulnerable and resilient phenotypes with AD

BACKGROUND: The heterogeneity of Alzheimer's disease (AD) and lack of well-validated markers of non-AD factors (e.g. TDP-43) present a substantial challenge for therapeutics. Our prior work showed discordance between tau (T) and neurodegeneration (N) identified non-AD factors in AD through multi-modality imaging. Here we tried a simplified approach using plasma ptau217 and medial temporal lobe (MT

Cardiac Rehabilitation Registries as Tools for Quality Improvement and Research : Insights From the SWEDEHEART-CR registry

Cardiac rehabilitation (CR) is a well established intervention for secondary prevention after myocardial infarction (MI), yet substantial variability in CR delivery and patient outcomes persists globally. This review provides an in-depth overview of the SWEDEHEART-CR registry, a comprehensive Swedish national quality registry that has facilitated continuous quality improvement and clinical researc

Exposome project for health and occupational research night shift cohort (EPHOR-NIGHT) : a unique resource to advance research on night shift work and chronic disease

Purpose The EPHOR-NIGHT cohort was established to investigate how night shift work influences biological pathways and chronic disease risk using a comprehensive working-life exposome approach, focusing on cardiometabolic, mental health, cognitive and biological ageing outcomes. Participant The cohort includes 937 workers aged 20–65 years (88%female), primarily from the healthcare sector (96%) in S

New Cam Profile Design Approach, Analysis and Testing for Extreme High Efficiency Internal Combustion Engine Development

The main objective of this work is to describe the design and testing of novel cam profiles, which are key for efficiency demonstration on a new class of internal combustion engine (ICE). A recuperated split cycle engine (RSCE) has unique demands for valve lift, duration and phasing when compared to a conventional 4-stroke. In particular, good control of the expander intake valve opening (IVO) app

Bend

Bend is a Naturum proposal located in Limhamn, Malmö, within a former limestone quarry. A Naturum is a Swedish visitor center designed to engage visitors with a site’s natural, cultural, and geological characteristics. In this project, Bend reinterprets the concept, translating the quarry’s qualities compression, fragility, and structural tension into architectural form. The design seeks to create

High gas-pressure apparatus for nonlinear X-ray propagation and reshaping via stimulated X-ray Raman scattering

We describe an experimental setup for non-linear interaction and propagation of ultrashort and intense x-ray free-electron laser (XFEL) pulses in a dense gas. It allows one to provide high, but adjustable, target-gas pressures of up to 6 bar within a vacuum environment of 3∙10− 3 mbar or better. The setup enables investigation of intense x-ray propagation in an optically thick medium with minimal

Major histocompatibility complex modulation of Batrachochytrium dendrobatidis and Ranavirus infections in amphibians

Genetic variation in immune genes is an important component of genetic diversity. The genes in the major histocompatibility complex (MHC) provide an excellent model system for studying the mechanisms that generate and maintain genetic diversity in natural populations. While both demographic factors and pathogen-mediated selection processes contribute to the extreme diversity observed in the MHC sy

Differential effects of overexpression of mutant huntingtin and TDP-43 in agouti-related protein neurons in the arcuate nucleus of the hypothalamus in mice

The spectrum of frontotemporal dementia/amyotrophic lateral sclerosis (FTD/ALS) and Huntington disease (HD) are fatal neurodegenerative disorders with no major disease-modifying therapies. Recent work has shown that the hallmark pathological proteins TAR DNA binding protein of 43 kDa (TDP-43) in FTD/ALS and mutant huntingtin (mHTT) in HD may be interlinked. Furthermore, these disorders share early

Plasma Protein Profile Associated With a Family History of Early-Onset Coronary Heart Disease

BACKGROUND: – Proteins linked to heritable coronary heart disease (CHD) could uncover new pathophysiological mechanisms of atherosclerosis. We report on the protein profile associated with a family history of early-onset CHD and whether the relation between proteins and coronary atherosclerotic burden differs according to family history status, as well as inferences from Mendelian randomization. M

Sex Differences in the Genetic Relationship Between Type 2 Diabetes and Cataract : Insights From East Asian and European Populations

Background: Type 2 diabetes (T2D) is a well-established risk factor for cataract. However, whether the causal effect on cataract differs by sex remains unclear. Determining whether this causal effect differs by sex could help resolve discrepancies in epidemiological studies regarding cataract risk in populations with diabetes. Methods: Using summary statistics of East Asian and European population

Genomic Insights Into Species Delimitation and the Evolutionary History of Mimetic Aletis Moths (Lepidoptera, Geometridae) in the Afrotropics

The evolutionary dynamics of diurnal Aletis moths (Lepidoptera: Geometridae: Sterrhinae) in the Afrotropics have been obscured by their allopatric distributions, significant inter- and intraspecific variation in adult and caterpillar phenotypes, and involvement in complex mimicry systems. Extensive phenotypic disparity, alongside conserved genital morphology and a lack of suitable material for gen

Longitudinal tau-PET accumulation and downstream effects in amyloid-beta negative cognitively unimpaired individuals

BACKGROUND: Previous studies, including ours (Wuestefeld et al., Brain, 2023), showed tau positron emission tomography (PET) uptake in medial temporal and neocortical regions of amyloid-beta (Aβ)-negative cognitively unimpaired (CU) individuals, associated with neurodegeneration and worse memory performance. To further understand if tau-PET uptake is clinically relevant in this population, we char

A probabilistic framework for the diagnostic utility of tau-PET

BACKGROUND: The tau-PET radiotracer [18F]flortaucipir enables in vivo detection of tau pathology in Alzheimer's Disease (AD) and has recently been FDA- and EMA-approved for clinical use. To support its implementation, we assessed tau-PET's positive predictive value (PPV) and negative predictive value (NPV) for clinico-pathological AD while accounting for age, amyloid-status, and pre-PET diagnostic
