Matched analysis of circulating selenium with the breast cancer selenotranscriptome: a multicentre prospective study

IntroductionLow serum selenium and altered tumour RNA expression of certain selenoproteins are associated with a poor breast cancer prognosis. Selenoprotein expression stringently depends on selenium availability, hence circulating selenium may interact with tumour selenoprotein expression. However, there is no matched analysis to date.MethodsThis study included 1453 patients with newly diagnosed

Electrostatic interactions control the adsorption of extracellular vesicles onto supported lipid bilayers

Communication between cells located in different parts of an organism is often mediated by membrane-enveloped nanoparticles, such as extracellular vesicles (EVs). EV binding and cell uptake mechanisms depend on the heterogeneous composition of the EV membrane. From a colloidal perspective, the EV membrane interacts with other biological interfaces via both specific and non-specific interactions, w

Design of an AI Support for Diagnosis of Dyspneic Adults at Time of Triage in the Emergency Department

We created an AI support for diagnosis in dyspneic adults at time of triage in the emergency department.Complete data from an entire regional health care system was analyzed, to find AI-derived, unknown, important diagnostic predictors. Most important were prior diagnoses of heart failure or COPD, daily smoking, atrial fibrillation/flutter, life difficulties and maternal care.Sensitivity for AHF,

MAC-1 marks a quiescent and functionally superior HSC subset during regeneration

Mouse hematopoietic stem cells (HSCs) have been extensively defined both molecularly and functionally at steady state, while regenerative stress induces immunophenotypical changes that limit high purity isolation and analysis. It is therefore important to identify markers that specifically label activated HSCs to gain further knowledge about their molecular and functional properties. Here, we asse

Intensiva regn i Malmö

Kortvariga intensiva regn med varaktighet upp till en timme åren 1980–2007 från nederbördsmätare i Malmöhar analyserats för att finna intensiteter med lång återkomsttid. Oberoende observationer för olika stationer harsammanförts till en serie till vilken sannolikhetsfördelningar anpassats. Korttidsregnmätningars tillförlitlighetdiskuteras. De extrema händelserna har behandlats individuellt. För atShort-term intensive storms of duration up to an hour the years 1980–2007 from rain gauges in Malmö havebeen analyzed to find intensities of long return periods. Non-dependent observations from different stationshave been combined into a series to which probability functions have been adjusted. The extreme events havebeen investigated individually. The reliability of rain measurements is discussed

3d Finite Element Models Reconstructed From 2d Dxa Images Improve Hip Fracture Prediction Compared to Areal Bmd in Mros Sweden Cohort

Bone strength is an important contributor to fracture risk. Areal bone mineral density (aBMD) derived from dual-energy X-ray absorptiometry (DXA) is used as a surrogate for bone strength in fracture risk prediction tools. 3D finite element (FE) models predict bone strength better than aBMD, but their clinical use is limited by the need for 3D computed tomography and lack of automation. We have ear

Environmental determinants of body mass index trajectories: results from a longitudinal Swedish study

Exposure to natural environments is thought to benefit mental and physical health. A better understanding of the interplay between the individual and the environment in relation to public health is imperative in light of the joint biodiversity, climate, and health crises. This study aimed to 1) identify Body Mass Index (BMI) trajectories in the Scania Public Health Cohort (SPHC), 2) characterise t

Intensive Data-Driven Model for Real-Time Observability in Low-Voltage Radial DSO Grids

Increasing levels of distributed generation (DG), as well as changes in electricity consumption behavior, are reshaping power distribution systems. These changes might place particular stress on the secondary low-voltage (LV) distribution systems not originally designed for bi-directional power flows. Voltage violations, reverse power flow, and congestion are the main arising concerns for distribu

Bimolecular Reaction Mechanism in the Amido Complex-Based Atomic Layer Deposition of HfO2

The surface chemistry of the initial growth during the first or first few precursor cycles in atomic layer deposition is decisive for how the growth proceeds later on and thus for the quality of the thin films grown. Yet, although general schemes of the surface chemistry of atomic layer deposition have been developed for many processes and precursors, in many cases, knowledge of this surface chemi

A Light Signaling Approach to Node Grouping for Massive MIMO IoT Networks

Massive MIMO is one of the leading technologies for connecting very large numbers of energy-constrained nodes, as it offers both extensive spatial multiplexing and large array gain. A challenge resides in partitioning the many nodes into groups that can communicate simultaneously such that the mutual interference is minimized. Here we propose node partitioning strategies that do not require full c

Dvärgagen vid Vombsjön 2013-2021, samt ett nyfynd vid Sövdesjön

Cyperus fuscus was thought to be extinct in Sweden until it was rediscovered at Lake Vombsjön, Skåne, after 63 years in 2013. The species also occurred at the lake 2014—2021, but in very variable numbers. The variation depended largely on the water level during late summer. Favourable conditions in form of low levels in late summer have also occurred prior to 2013, though less frequently than in r

A pilot study of AI-assisted reading of prostate MRI in Organized Prostate Cancer Testing

Objectives: To evaluate the feasibility of AI-assisted reading of prostate magnetic resonance imaging (MRI) in Organized Prostate cancer Testing (OPT). Methods: Retrospective cohort study including 57 men with elevated prostate-specific antigen (PSA) levels ≥3 µg/L that performed bi-parametric MRI in OPT. The results of a CE-marked deep learning (DL) algorithm for prostate MRI lesion detection wer

Mammographic features differ with body composition in women with breast cancer

Objectives: There are several breast cancer (BC) risk factors—many related to body composition, hormonal status, and fertility patterns. However, it is not known if risk factors in healthy women are associated with specific mammographic features at the time of BC diagnosis. Our aim was to assess the potential association between pre-diagnostic body composition and mammographic features in the diag

Valence photoelectron spectra of aminobenzoic acid molecules : a combined theoretical and experimental study

The valence photoelectron spectra (PES) of gas-phase aminobenzoic acids (meta-, ortho- and para-isomers) were measured using synchrotron radiation and calculated from first principles using Density Functional Theory (DFT) with popular hybrid exchange-correlation functionals and many-body perturbation theory using the perturbative one-shot (G0W0) and eigenvalue self-consistent (GnW0) approaches wit

Estimation of Panel Data Models with Random Interactive Effects and Multiple Structural Breaks when T is Fixed

In this article, we propose a new estimator of panel data models with random interactive effects and multiple structural breaks that is suitable when the number of time periods, T, is fixed and only the number of cross-sectional units, N, is large. This is done by viewing the determination of the breaks as a shrinkage problem, and to estimate both the regression coefficients, and the number of bre

Biomass cookstove emissions—a systematic review on aerosol and particle properties of relevance for health, climate, and the environment

Around one-fourth of the global population lacks access to clean fuels and technologies for cooking, most of them living in low- and middle-income countries. Reliance on rudimentary and inefficient biomass cookstoves results in high pollutant concentrations that adversely affect the health of those exposed to indoor air pollution, the environment, and the climate. In this study, we systematically

Diurnal migration patterns in willow warblers differ between the western and eastern flyways

It is a long-standing view that the main mechanism maintaining narrow migratory divides in passerines is the selection against intermediate and suboptimal migratory direction, but empirical proof of this is still lacking. We present novel results from a willow warbler migratory divide in central Sweden from where birds take the typical SW and SE as well as intermediate routes to winter quarters in

Diabetic status and the performances of creatinine- and cystatin C–based eGFR equations

Background. The estimation of glomerular filtration rate (GFR) is one tool to detect renal disease. The most used biomarker remains serum creatinine and the European Kidney Function Consortium (EKFCcrea ) equation is the most validated in Europe. More recently, cystatin C has been proposed as a biomarker. We studied the performances of the EKFC equations in a large cohort of subjects according to
