Protein aggregation is a key process in the development of many neurodegenerative disorders, including dementias such as Alzheimer's disease. Significant progress has been made in understanding the molecular mechanisms of aggregate formation in pure buffer systems, much of which was enabled by the development of integrated rate laws that allowed for mechanistic analysis of aggregation kinetics. Ho
BACKGROUND: Polycystic ovary syndrome (PCOS) has previously been associated with several comorbidities that may have shared genetic, epigenetic, developmental or environmental origins. PCOS may be influenced by prenatal androgen excess, poor intrauterine or childhood environmental factors, childhood obesity and learned health risk behaviors. We analyzed the association between PCOS and several rel
We present a novel, interferometric, two-color, high-order harmonic generation setup based on a turn-key Ytterbium-doped femtosecond laser source and its second harmonic. Each interferometer arm contains a spatial light modulator with individual capabilities to manipulate the spatial beam profiles and to stabilize the relative delay between the fundamental and the second harmonic. In addition, sep
AIMS: Parameters derived from reservoir-excess pressure analysis have been demonstrated to predict cardiovascular events. Thus, altered reservoir-excess pressure parameters could have a detrimental effect on highly-perfused organs like the heart. We aimed to cross-sectionally determine whether reservoir-excess pressure parameters were associated with N-terminal pro-brain-type natriuretic peptide (
Significant progress has been made in elucidating genetic risk factors influencing Type 1 diabetes (T1D); however, features other than genetic variants that initiate and/or accelerate islet autoimmunity that lead to the development of clinical T1D remain largely unknown. We hypothesized that genetic and environmental risk factors can both contribute to T1D through dynamic alterations of molecular
BackgroundMale involvement in maternal health care has proven to be beneficial for improving maternal and child health and is often crucial in areas of family planning and contraceptive use. However, compared to male involvement in maternal health care, male involvement in contraceptive counselling is complex and controversial and thus faces certain challenges. Immigrant men in Sweden are often ac
Background and objective: We established prognostic nomograms incorporating prostate-specific membrane antigen (PSMA) positron emission tomography (PET) parameters standardised by Prostate Cancer Molecular Imaging Standardized Evaluation (PROMISE; PPP1). Here, we develop an updated PPP2 risk score from a large international multicentre registry study. Methods: We included 6128 prostate cancer pati
Legumin and vicilin, the main storage proteins from peas, are increasingly employed as functional ingredients for food. The purpose of this work was to better understand the interactions between these proteins and selected lipids, due to their potential consequences on interfacial functionality of protein preparations. Legumin and vicilin isolates were obtained after isoelectric precipitation foll
Solvent cage-escape dynamics of bimolecular photoredox products in solution has been investigated computationally through a combination of molecular dynamics simulations and quantum chemical calculations. The present work focuses on the photoinduced oxidation of the organic electron donor dimethylaniline (DMA) by a Fe(III) N-heterocyclic carbene photosensitizer (Fe(III)NHC+) in two different solve
We present a novel method for in-line acoustofluidic separation of cancer cells directly from whole blood. We report for the first time the observation that blood cells can self-organize when packed closely together in an acoustic field. We utilize this effect to enrich K-562 cancer cells and white blood cell subpopulations from whole blood at normal hematocrit levels. Further, we investigate the
Three different semiconductor nanowires are combined into a single optoelectronic artificial neuron. Our device provides a path towards low power computations with significantly reduced circuit footprint, thus addressing critical limitations in neuromorphic photonics. The false-coloured scanning electron micrograph shown in Figure 1a depicts the fabricated nanowire neuron. Two pin-doped InP nanowi
Photonics-based approaches to neuromorphic hardware offer advantages in speed and connectivity but often suffer from large device footprints.[1] Here, we present an ultra-compact artificial neuron built from semiconductor nanowires. A scanning electron micrograph of the nanowire device is presented in Figure 1a. Inside the dashed box, we show the neuron built from three III-V nanowires - two InP p
BACKGROUND: Diagnosing heart failure with preserved ejection fraction (HFpEF) remains challenging, particularly in older adults. While the Heart Failure Association (HFA)-PEFF and H2FPEF Scores offer structured diagnostic approaches, their clinical utility is still debated. This study aims to compare the diagnostic accuracy of HFpEF Scores versus inclusion criteria used in sodium-glucose cotranspo
Background: Around 95% of all websites selling medicines globally are illegal and contribute to the spread of substandard and falsified medicines. Hence, it is important to identify legal pharmacies when accessing medicines online. During 2022-2024, 250 million prescriptions were legally dispensed in Sweden, and 69% were prescribed in primary care. Pharmacists and general practitioners are key hea
Background: This study compared levels of physical activity (PA) and sedentary behavior (SB) in adults with and without chronic diseases or multimorbidity, acknowledging sociodemographic factors. Methods: A cross-sectional analysis was conducted with data from 27,890 participants (52% women), aged 50–64, from the Swedish CArdioPulmonary bioImage Study cohort. Over 1500 chronic diseases were includ
Isolated attosecond pulses are often generated via sub-optical-cycle polarization gating. This technique, based on the precise control of the time-dependent polarization of the infrared driver pulse, enables strong temporal confinement of the extreme ultraviolet (XUV) emission from high-order harmonic generation (HHG) in gases. In this work, we study the influence of pulse propagation between the
The aggregation of tau into amyloid fibrils is associated with Alzheimer’s disease (AD) and related tauopathies. Since different tauopathies are characterized by the formation of distinct tau fibril morphologies, it is important to combine the search of tau aggregation inhibitors with the development of in vitro tau aggregation assays that recapitulate aggregation as it may occur in the brain. Her
Methane dry reforming not only utilizes two potent greenhouse gases of methane and carbon dioxide, but also provides a valuable feedstock for the production of chemicals. However, this process has been heavily hindered by high operating temperature and coke formation with catalyst deactivation over the last century. Herein, we propose an approach whereby concentrated-solar catalytic methane dry re
