Quantifying the impact of early life growth adversity on later life health

Background: Early-life growth adversity is important to later-life health, but precision assessment in adulthood is challenging. We evaluated whether the difference between attained and genotype-predicted adult height (“height-GaP”) would associate with prospectively ascertained early-life growth adversity and later-life all-cause and cardiovascular mortality. Methods: Data were first analyzed fro

WES-Based Screening of a Swedish Patient Series with Parkinson’s Disease

Background/Objective: Genetic factors contribute significantly to Parkinson’s disease (PD), especially in cases with early onset or positive family history. However, previous investigations of the genetic landscape in PD populations were mainly based on targeted genotyping. The aim of this study was to investigate the prevalence of pathogenic variants in known PD-associated genes in a series of Sw

α-Synuclein cooperative binding to lipid membranes is a robust property over a wide range of conditions

Cooperativity is an efficient way for nature to regulate complex processes, allowing for control over a narrower range of concentrations compared to noncooperative phenomena. Here, we investigate the cooperative binding of α-Synuclein to lipid membranes under different conditions, aiming to uncover the underlying molecular driving forces. We interrogate the role of electrostatic interactions by ra

Chemically inert microfluidic flow regulator with a glass-Teflon2-glass structure fabricated via facile thermal bonding

Recent advancements in integrated chemical microsystems have significantly enhanced the efficiency and precision of chemical synthesis. However, limitations in current materials and fabrication technologies pose challenges to developing robust flow regulation essential for system operation and scalability. This study presents a cleanroom-free, surface-modification-free bonding method for fabricati

Designing a Femtosecond-Resolution Bunch Length Monitor Using Coherent Transition Radiation Images

Ultrashort bunch length measurements are crucial for characterizing electron beams in short-pulse accelerators, including novel accelerators like EuPRAXIA and those used for free-electron lasers (FELs). This work provides an overview of the design process and the current status of a single-shot bunch length monitor prototype based on a broadband spatial imaging system for coherent transition radia

Adolescents’ Well-Being, Self-Esteem, and Academic Motivation as Bystanders : A Grounded Theory of Authenticity in Witnessing Bullying

Bullying is increasingly understood as a group-based phenomenon in which bystanders play a critical role, yet little is known about how witnessing bullying affects bystanders’ self-esteem and academic motivation. The aim of this study was to explore adolescents’ perspectives on how witnessing bullying in school may be linked to their self-esteem and academic motivation. This qualitative study expl

Implementing electronic informed consent in rare disease genomics

In rare disease research, sharing of individual health data is essential for advancing diagnostics and therapies, requiring robust and ethically sound informed consent processes. Within the Genomic Medicine Sweden Rare Diseases (GMS-RD) multicenter study, an electronic informed consent (eConsent) platform was developed to support data sharing, facilitate participation and enable research engagemen

Computationally efficient whole-genome quantile regression at biobank scale

Genotype–phenotype associations can be context-dependent and dynamic in nature leading to heterogeneity of genetic effects across different parts of the phenotype distribution. Quantile regression, an alternative to linear regression for continuous phenotypes, is particularly well suited for detecting and characterizing heterogeneous genotype–phenotype associations. Here, we propose a computationa

Discursive Discrimination Ableism and Linguicism in Governmental Documentation – The Case of Swedish Sign Language

Swedish Sign Language [svenskt teckenspråk, STS] has often been described as being the first officially recognised sign language in the world, passed into law in 1981. This was a parliamentary decision that later led to the provision of bimodal-bilingual education and the keeping of a separate school system for deaf students. However, today, STS is not granted the same rights as the five declared

The performance of masculinities in the 2025 presidential elections in Romania

This article examines the 2025 Romanian presidential runoff through the lens of gendered political leadership. It explores the contours of different types of masculinities in politics as performed by the two candidates, George Simion and Nicușor Dan. We analyse the political meanings of gender and sexuality in the candidates’ performances of masculinity and how these both reflect and contest Roman

The Major Outer Membrane Protein P5 Binds Vitronectin to Mediate Serum Resistance in Nontypeable Haemophilus influenzae

Acquisition of complement regulators is a virulence strategy used by nontypeable Haemophilus influenzae (NTHi) to evade complement-mediated killing by the host. The major outer membrane protein of NTHi, P5, binds C4b-binding protein and factor H to promote bacterial serum resistance. We show that P5 also binds vitronectin, which inhibits the formation of the membrane attack complex at the terminal

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

Contextual adaptation, implementation, and outcomes of individual placement and support: a case study

Background: Implementing the evidence-based Individual Placement and Support (IPS) model in welfare states like Sweden faces contextual challenges that often necessitate local adaptations to enhance fit and effectiveness. While fidelity assessments aim to ensure effective outcomes, adaptations may lead to unintended drift from core components.

Hemispheric Asymmetry of Amyloid Deposition Influences Asymmetric Tau Pathology in Alzheimer’s Disease

BACKGROUND: Tau pathology distribution in Alzheimer's disease (AD) shows individual spatial heterogeneity, including hemispheric asymmetry. The mechanisms underlying this asymmetry remain unclear. This study explored whether tau asymmetry is linked to reduced inter-hemispheric connectivity, potentially restricting tau spread, or reflects asymmetry in amyloid-beta (Aβ) distribution, indicating hemi

Associations between regional amyloid PET and genome-wide polygenic risk scores in the predementia AMYPAD consortium

BACKGROUND: Variability of brain amyloid burden across individuals suggests that biological factors may play a role. This study investigates the association between polygenic risk scores (PRS) and amyloid burden in a preclinical Alzheimer's disease (AD) cohort to identify genetic determinants. METHOD: PRS for AD susceptibility (Kunkle et al., 2019) and for CSF-Aβ42 and ptau181 (Jansen et al., 2022

Domestication may have unintentionally increased arsenic accumulation in japonica rice

Arsenic contamination in soil and water poses significant health risks globally through contaminated crops. 1,2,3 Modern cultivated rice ( Oryza sativa ), particularly the subspecies japonica , accumulates high levels of arsenic. 1,3,4,5,6 This may possibly result from unintended physiological and genomic changes during rice domestication, which have significantly altered traits such as plant arch

Brain structural-functional coupling is differentially affected by age, sex, and amyloid burden in older individuals without dementia

BACKGROUND: Brain function emerges from structural pathways enabling neural connectivity and communication. However, the extent of structural-functional coupling varies across brain regions, and its alteration in aging and early Alzheimer's disease (AD) remains unclear. This study investigated variations in coupling associated with age, sex, and amyloid burden in a cohort of older adults without d

High-resolution postmortem 7 tesla MRI yields localized atrophy measures that are more sensitive to tau pathology and neuronal loss in Alzheimer’s disease than corresponding measures on antemortem 3 tesla MRI

BACKGROUND: Postmortem MRI has opened-up avenues to study brain structure at ultra high-resolution revealing details not possible to observe with in vivo MRI. Here, we present a novel package (purple-mri) which performs tissue segmentation, anatomical parcellation and spatial normalization of postmortem MRI. Additionally, we provide a framework to perform point-wise surface-based group-level studi
