On the self-assembly of αB-crystallin

The molecular chaperone αB-crystallin is a small heat shock protein that inhibits the aggregation of, among others, Aβ42 and α-synuclein. These proteins are major hallmarks of Alzheimer's and Parkinson's disease, respectively. In order to understand the mechanism with which αB-crystallin performs its chaperone function it is essential to characterize its self-assembly in terms of aggregate size di

Alzheimer's disease outlook : controversies and future directions

For the first time, reductions in cerebral β-amyloid pathology load and rate of cognitive and functional decline have been achieved in Alzheimer's disease, through pharmacological intervention in randomised controlled trials. However, the results from phase 3 randomised controlled trials of anti-β amyloid monoclonal antibodies are interpreted in different ways, with some experts supporting a clini

Intra-Operative Onychoscopy of Subungual Epidermoid Inclusions

Subungual epidermoid inclusions (SEI) are small epithelial inclusions, sometimes solid but mostly with central keratinization of the onycholemmal type without a granular layer. Exceptionally, they become large enough to produce symptoms such as pain or swelling of the nail bed, resulting in subungual keratosis, onycholysis, or a dystrophic nail plate. Herein, we report a further case of SEI in a f

Disciplinary and Methodological Pluralism in Loneliness Studies

Scientists may benefit from implementing interdisciplinary and multi-method approaches when studying loneliness. Loneliness is a complex phenomenon that is influenced by biological, psychological, social, cultural, and political factors. In addition, it also reflects and impacts personal and local experiences as well as broader social forces, thus being both universal and contextual at the same ti

Association between metabolic conditions, physical activity and self-efficacy before and after a first-line exercise and education intervention for osteoarthritis : a longitudinal register study using the SOAD cohort

Objectives To investigate the association of diabetes, hypertension and overweight/obesity with physical activity (PA), self-efficacy for pain and self-efficacy for other symptoms before and after a 6- week exercise and education intervention for knee and hip osteoarthritis (OA), and to assess outcome disparities based on metabolic health. Methods Register-based cohort study using the Swedish Oste

Association of type 2 diabetes with reoperation, adverse events and mortality after hip and knee replacement : a Swedish register-based study including 109 938 hip and 80 897 knee replacements

Objective Type 2 diabetes mellitus (T2DM) and osteoarthritis (OA) are globally prevalent chronic diseases that affect millions of individuals in ageing populations. Hip and knee replacements are well established and effective treatments in patients suffering from end-stage OA. Understanding how T2DM influences the outcomes of these surgeries is important for optimising patient care and improving s

Seasonal differences in observed versus modelled new particle formation at two European boreal stations

Realistic representation of atmospheric aerosol size distribution dynamics in large-scale climate models is important for developing accurate descriptions of aerosol-cloud interactions. Despite the dynamic nature of the distributions, which have large seasonal and diurnal changes, model evaluations often focus on the annual median size distribution. Using more comprehensive monthly and diurnal mod

The melanoma MEGA-study : Integrating proteogenomics, digital pathology, and AI-analytics for precision oncology

Melanoma remains the most aggressive form of skin cancer, characterized by high metastatic potential, genetic heterogeneity, and resistance to conventional therapies. The Melanoma MEGA-Study is a multi-center initiative designed to address these clinical challenges by integrating advanced proteogenomic profiling, clinical metadata, with AI-driven digital pathology and machine learning analytics, a

New landscape of the diagnosis of Alzheimer's disease

Alzheimer's disease involves a drastic departure from the cognitive, functional, and behavioural trajectory of normal ageing, and is both a dreaded and highly prevalent cause of disability to individuals, and a leading source of health and social care expenditure for society. Before the advent of biomarkers, post-mortem examination was the only method available to establish a definitive diagnosis.

Work absence in parents of youth who self-harm

Background Self-harm is a prevalent health concern among youths, with significant psychosocial impacts on both youths and their parents. The aim of this study is to describe the impact of offspring self-harm on parental work absence. Methods This cohort study included 176 472 mothers and 161833 fathers of 17 726 youths with a first self-harm diagnosis between the years of 2006 and 2016 and 177 260

Classifying a distinct form of diabetes in lean individuals with a history of undernutrition : an international consensus statement

Since 1955, a form of diabetes in lean, young (BMI <18·5 kg/m2, age <30 years) individuals with a history suggestive of undernutrition from before birth and throughout childhood has been described in the literature. In 1985, WHO formally classified it as malnutrition-related diabetes, but subsequently removed the classification in 1999 over a disagreement as to whether undernutrition was a suffici

Implementing a process-based representation of soil water movement in a second-generation dynamic vegetation model : application to dryland ecosystems (LPJ-GUESS-RE v1.0)

Dryland ecosystems are globally important, yet state-of-the-art dynamic vegetation models often lack specific processes or parameterizations that are critical for accurately simulating dryland dynamics. These missing processes include a realistic calculation of soil water movement, detailed plant–water relations, or a representation of deep water uptake. In this study, we show how including a proc

Using the structure of the residuals to evaluate the goodness of fit : a pedagogical case study with Newton’s law of cooling

Introductions to data analysis in university physics often focus on fitting (typically to linearised functions) and uncertainty propagation, but residuals are less commonly introduced. Structured residuals indicate that the function (theoretical description) used to fit data does not capture all the relevant elements (i.e. the theoretical description is incomplete), and can be present even when th

The physiological cost of leadership in collective movements

Individuals can gain substantial benefits from collective actions.1,2,3,4,5,6,7 However, collective behaviors introduce new challenges, like coordinating actions, maintaining cohesion, and meeting the needs of different individuals. When making collective movements, leaders are typically thought to gain disproportionate benefits through the choice of more beneficial resources3 and/or earlier acces
