RNA-directed transposon silencing operates in the mammalian soma and germline to safeguard genomic integrity. The piRNA pathway and the HUSH complex identify active transposons through recognition of their nascent transcripts, but mechanistic understanding of how these distinct pathways evolved is lacking. TASOR is an essential component of the HUSH complex. TASOR's DUF3715 domain adopts a pseudo-
Here we study the influence of particle size on the formation of antiferromagnetic FexO subdomains and the emergence of exchange bias in novel ferrimagnetic Cr-substituted Fe3O4 nanoparticles generated using an aerosol technique based on spark ablation. Cooling in an applied magnetic field across the Néel temperature of the FexO subdomains results in significant shifts in the hysteresis loops, whi
Recent studies have revealed a close connection between cellular metabolism and the chronic inflammatory process of atherosclerosis. While the link between systemic metabolism and atherosclerosis is well established, the implications of altered metabolism in the artery wall are less understood. Pyruvate dehydrogenase kinase (PDK)-dependent inhibition of pyruvate dehydrogenase (PDH) has been identi
Cellular senescence is a state in which cells enter cell cycle arrest. However, senescent cells have the ability to secrete signaling molecules such as chemokines, cytokines, and growth factors. This secretory activity is an important feature of senescent cells, since the secreted factors impact the surrounding cellular microenvironment. Indeed, senescent cells and their secretome play a crucial r
Background: The ankle–brachial index (ABI) is the ratio of the ankle and brachial systolic blood pressures. In the clinical setting, low ABI (< 0.9) is an indicator of peripheral atherosclerosis, while high ABI (> 1.4) is a sign of arterial stiffness and calcification. The purpose of the current study was to investigate the association between ABI and physical activity levels, measured by accelero
Background: Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis is a heterogenous autoimmune disease. While traditionally stratified into two conditions, granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA), the subclassification of ANCA-associated vasculitis is subject to continued debate. Here we aim to identify phenotypically distinct subgroups and develop a da
BACKGROUND:Postural orthostatic tachycardia syndrome (POTS) is a frequently diagnosed cardiovascular disorder after COVID-19 infection. POTS is characterized by the presence of excessive sinus tachycardia on standing without a fall in blood pressure (BP). We investigated the BP profile using 24-hour ambulatory BP monitoring in patients with new-onset POTS after COVID-19 compared with prepandemic p
Extracellular vesicles (EVs) are membrane enclosed biological nanoparticles released by cells. In the past two decades, EVs have gained a lot of attention due to their role in numerous biological processes. However, their small nature complicates isolating them from biological fluids with cumbersome techniques, such as ultracentrifugation. Acoustic trapping is a technique that uses ultrasonic stan
Background: Lifestyle choices, metformin, and dietary supplements may prevent GDM, but the effect of intervention characteristics has not been identified. This review evaluated intervention characteristics to inform the implementation of GDM prevention interventions. Methods: Ovid, MEDLINE/PubMed, and EMBASE databases were searched. The Template for Intervention Description and Replication (TIDieR
Quantum interference (QI) can strongly affect electric and thermoelectric properties of molecular junctions (MJs). So far, however, a limited number of experimental studies have explored the influence of QI on thermoelectric transport in MJs. To address this open point, we synthesized derivatives of meta-OPE3 with an electron-withdrawing nitro (-NO2) substituent or an electron-donating N,N-dimethy
Background: The diagnostic accuracy of digital breast tomosynthesis (DBT) and digital mammography (DM) in breast cancer screening may vary per breast density subgroup. The purpose of this study was to evaluate which women, based on automatically assessed breast density subgroups, have the greatest benefit of DBT compared with DM in the prospective Malmö Breast Tomosynthesis Screening Trial. Materi
Background: Childhood cancer predisposition (ChiCaP) syndromes are increasingly recognized as contributing factors to childhood cancer development. Yet, due to variable availability of germline testing, many children with ChiCaP might go undetected today. We report results from the nationwide and prospective ChiCaP study that investigated diagnostic yield and clinical impact of integrating germlin
Personal Protective Equipment (PPE) noncompliance has been addressed through various lenses. In current literature, there is a greater focus on improving training and safety culture. Improving PPE design to persuade PPE compliance is less explored, especially in sectors beyond healthcare. This study investigates the reasons behind PPE noncompliance across construction, maritime, and chimney sweepi
Accessible housing for the aging population is important, but large-scale reliable information on accessibility problems in ordinary housing is lacking. This study aimed to describe the prevalence of environmental barriers and analyze potential accessibility problems in the Swedish housing stock and to evaluate the validity and representativeness of housing data collected in a citizen science proj
Hypertension affects more than one billion people worldwide. Here we identify 113 novel loci, reporting a total of 2,103 independent genetic signals (P < 5 × 10−8) from the largest single-stage blood pressure (BP) genome-wide association study to date (n = 1,028,980 European individuals). These associations explain more than 60% of single nucleotide polymorphism-based BP heritability. Comparing to
High-order harmonic generation (HHG) provides scalable sources of coherent extreme ultraviolet radiation with pulse duration down to the attosecond time scale. Efficient HHG requires the constructive interplay between microscopic and macroscopic effects in the generation volume, which can be achieved over a large range of experimental parameters from the driving field properties to those of the ge
