Background: Sport-related concussion (SRC) is a common and complex injury in athletic populations. Linear head acceleration (LHA) and rotational head acceleration (RHA) are key biomechanical factors believed to contribute to SRC, each through distinct mechanisms. Evaluating head impact magnitudes across different sports, athlete populations, and measurement methods is essential for advancing SRC

How do actors overlook uncomfortable information? We add to the understanding of how potential problems can be ignored over long periods, in spite of recurrent warnings. Ignoring then becomes a dynamic process of responding to evolving ignoring ‘threats’ or triggers by combining knowledge-seeking and knowledge avoidance in ways that must be continuously legitimated, both in one’s own eyes and in t

Serglycin (SRGN) has been found overexpressed and secreted in glioblastoma (GBM), associated with tumorigenic signaling and poor prognosis. In this study, we aimed to elucidate the involvement of SRGN in the unfolded protein response (UPR), an oncogenic signaling pathway implicated in protein recycling and cell fate. Herein, we developed stably transduced LN-18shSCR GBM cells, expressing high leve

As populations age, many countries are raising retirement ages and encouraging longer working lives. In Sweden, where old-age employment rates are already high, questions remain about how these patterns vary across regions and labour market segments. This article provides a comprehensive overview of old-age employment trends from 1990 to 2021, using detailed population register data. While employm

Direct reprogramming offers a powerful approach to generate therapeutic cell types, but progress is limited by an incomplete understanding of transcription factor (TF) cooperativity. Here, we present a protocol for performing combinatorial TF screening to resolve reprogramming factor networks that drive cell identity. We describe steps for arrayed lentiviral production, transduction, and reprogram

In October 2023, storm Babet led to the most severe erosion in decades along the Swedish South coast. In this study we approach the affected coastal landscape as a coupled social-ecological system where environmental components (e.g. geology, bathymetry, waves) interact with social components (e.g. infrastructure, management, economic activities) to influence the outcome of an extreme event. We us

Neurofilament light chain (NfL) is a promising biomarker of axonal injury across acute and chronic neurodegeneration, which can improve drug discovery and disease monitoring models. Traditional in vivo animal models cannot fully mimic human pathophysiology of neurodegenerative diseases (NDDs), but in vitro models based on human cells solve this problem, reducing the time and cost of drug testing.

Time-resolved imaging of plasmonic near fields is well-established at visible wavelengths but remains largely unexplored in the short-wavelength infrared (SWIR) range. Here, we use time-resolved photoemission electron microscopy (TR-PEEM) to directly visualize ultrafast plasmon dynamics in silver nanowires driven by a few-cycle SWIR pulses. We observe strong electric-field enhancement localized at

Granulomas are organized immune aggregates of myeloid and lymphoid cells that arise when the host fails to eliminate persistent stimuli; however, their function remains paradoxical, by promoting both protection from systemic dissemination while also promoting a niche for microbial survival. Traditionally defined by histopathology and morphology, granulomas are now being revisited with high-through

Alzheimer's disease (AD) is marked by progressive cognitive decline, highlighting the importance of cognitive assessment in both clinical practice and research. This study investigates the temporal dynamics of cognitive decline and the differential sensitivity of cognitive measures across the AD spectrum. Cognitive measures, functional assessments, and amyloid-beta (Aβ) and tau positron emission t

Background: Metastasis-directed stereotactic body radiotherapy (MD-SBRT) has shown promise in retrospective and phase II studies for oligometastatic hormone-sensitive prostate cancer. However, prospective randomized phase III data—particularly in newly diagnosed cases and in combination with androgen deprivation therapy and next-generation androgen receptor pathway inhibitors—are limited. The METR

This work evaluates a standardized 30-ton, 16 m railbus platform optimized for unelectrified regional service, focusing on propulsion system design and trade-offs between range, cost, and emissions. A MATLAB/Simulink drive-cycle model was developed to simulate energy consumption and component performance under realistic operating conditions. The Erfurt–Rennsteig route in Germany (130 km round trip

In multi-user multiple-input multiple-output (MU-MIMO) systems, the non-linear behavior of the power amplifiers (PAs) may cause degradation of the linear precoding schemes dealing with interference between user equipments (UEs), e.g., the zero-forcing (ZF) precoder. One way to minimize this effect is to use digital-pre-distortion (DPD) modules to linearize the PAs. However, using perfect DPD modul

One of the key ecological processes affected by climate change is plant carbon uptake. However, there is substantial uncertainty about how plant carbon uptake will respond to warming in mountain ecosystems, which are known for sharp temperature gradients and abrupt shifts in vegetation structure. Specifically, we lack an understanding of whether these response trajectories over time will be linear

Introduction: Enhancing Quality of Life for Individuals with Stroke (EQL-stroke) is an international, collaborative multiphase project aiming to strengthen supported self-management for older adults recovering from stroke at home in Sweden, Latvia and the Netherlands. Existing poststroke pathways may provide insufficient support for self-management during the transition from hospital to home, and
