Photonic topological insulators and self-induced nonreciprocity based on nonlinear effects in asymmetric structures have garnered increased attention due to their potential applications in quantum information technologies and advanced photonic integrated circuits. In this study, we combine these two fields and present asymmetric photonic crystal designs based on all-dielectric checkerboard structu
Objective Delivery of a small for gestational age (SGA) infant is a common pregnancy complication among women with SLE. Although disease activity and autoantibodies such as anti-Smith and anti-ribonucleoprotein associate with SGA, underlying pathological mechanisms remain unclear and reliable predictors are lacking. To address this, we applied a proteomic approach to identify proteins associated w
Background Preserved ratio impaired spirometry (PRISm) and restrictive spirometry pattern (RSP) are associated with increased morbidity and mortality, but the underlying mechanisms are unclear. Impulse oscillometry (IOS) measures small airway function more sensitively than spirometry. We aim to study the prevalence of abnormal IOS findings in relation to three spirometry patterns (obstructive, PRI
BACKGROUND: Cardiovascular calcification is a significant predictor and contributor to cardiovascular diseases. Vascular smooth muscle cell (SMC)-derived extracellular vesicles (EVs) play a crucial role in microcalcification formation. EVs can originate from the endosomal system, and PIKFYVE (1-phosphatidylinositol 3-phosphate 5-kinase), a lipid kinase, plays a key role in endomembrane maturation.
IntroductionSport-related concussion (SRC) is a pressing issue in Para sport, yet biomechanical mechanisms remain poorly understood. Athletes with visual impairment face elevated risks due to sport-specific demands, such as frequent collisions in blind football. This pilot study examined head acceleration responses in blind football players compared with non-disabled football players, and between
Introduction: It is well known that urinary tract infection (UTI) during pregnancy is associated with preterm birth, but information about the risk of preterm birth depending on gestational week of infection is sparingly described in the literature. Material and Methods: An observational study based on data from Swedish registers including women giving birth 2014–2020 (n = 684 595). Pregnant women
Objective: To describe longitudinal changes of Magnetic Resonance Imaging (MRI) features in the medial vs lateral tibiofemoral (TF) and patellofemoral (PF) compartments, in knees with no radiographic osteoarthritis (OA) at baseline. Design: In 340 individuals from the Osteoarthritis Initiative aged 45–55 years (51% women) with 430 knees at risk for OA and 250 not at risk, we assessed MRI scans of
Background: Pro-neurotensin (pro-NT) is the stable circulating precursor of neurotensin (NT), a neuropeptide expressed mainly in the central nervous system and small intestine that regulates key physiological processes like fatty acid absorption in the gut and suppresses appetite via central mechanisms. Studies in NT-deficient mice and humans implicate NT in obesity and insulin resistance, highlig
Hyperbolic phonon polaritons - hybridized modes arising from the ultrastrong coupling of infrared light to strongly anisotropic lattice vibrations in uniaxial or biaxial polar crystals - enable to confine light to the nanoscale with low losses and high directionality. In even lower symmetry materials, such as monoclinic (Formula presented.) -Ga2O3 (bGO), hyperbolic shear polaritons (HShPs) further
Aims: Testing insulin resistance could help improve physician assessment of patients’ risk of prediabetes or type 2 diabetes (T2D), even among normoglycemic individuals. Methods: The longitudinal study followed 16,333 normoglycemic participants in a nation-wide employer-sponsored health assessment program starting in August 2020 with a median follow-up time of 2.9 years for incident prediabetes or
Several factors contribute to the use, non-use, or inadequate use of personal protective equipment (PPE) in construction work. This study aimed to analyse correct usage of various PPE, such as helmet, ear protectors, goggles, respiratory mask, gloves, protective clothing, and a safety harness. Correct usage was assessed as guessability, which refers to human perceptions of how to don, adjust, use,
ObjectivesTo compare head acceleration between blind football players and non-disabled football players, and between anticipated and unanticipated conditions in blind football players.DesignLaboratory-based exploratory study.MethodsParticipants were ten football players (five blind football, five non-disabled; 80% female). Standardized head perturbations were applied in flexion, extension, lateral
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
The energy system is undergoing significant changes and is expected to continue to evolve. Energy demand is anticipated to increase, as is renewable energy capacity, and technical solutions are advancing. For electrical power, traditionally centralized production is increasingly complemented by distributed production, transforming fundamental system functionality. These developing factors will aff
Objective: Interstitial lung disease (ILD) can occur in association with antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV-ILD) or as an isolated entity with positive ANCA (ANCA-ILD). However, data on the epidemiology and outcomes of these conditions remain limited. Methods: A European multicenter retrospective study encompassed patients with AAV-ILD or ANCA-ILD. Baseline and s
Bacteria encode diverse defence systems, including restriction-modification and CRISPR-Cas, that cleave nucleic acid to protect against phage infection. Bioinformatic analyses demonstrate that many recently identified antiphage defence operons comprise a nuclease and NTPase protein, suggesting that additional nucleic acid-targeting systems remain to be understood. Here we develop large-scale compa

A high turnover among principals may disrupt the continuity of leadership and negativelyaffect teachers and, by extension, the students. The aim was to investigate to what extent variouswork environment factors and signs of exhaustion were associated with reported intentions tochange workplace among principals working in compulsory schools. A web-based questionnaire wasadministered twice, in 2018
Small for gestational age (SGA) is considered an adverse birth outcome. Per- and polyfluoralkyl substances (PFAS) have become increasingly investigated as contributing environmental factors, thus far with inconclusive results. The current study aimed to investigate the hypothesized association between increased maternal PFAS levels in early pregnancy and an increased risk for SGA birth. This popul
Migratory birds must make complex decisions to use wind to their advantage during flight and increasing flight performance is particularly important while crossing ecological barriers. Age-related differences in how birds deal with wind have suggested experience improves necessary skills in gaining positive wind support. However, differences in wind support between age groups over ecological barri
