Size-based sorting of dynamic bacterial clusters

Group A Streptococcus (GAS) forms highly deformable aggregates with broad variations in size and morphology, complicating controlled separation and biological analysis. Reliable methods to isolate fractions of GAS clusters with defined properties are essential for studying host–pathogen interactions that depend on cluster size. Here, we present a simple deterministic lateral displacement (DLD) mic

The domestic pig as a translational model of hyperoxaluria : a pilot study of acute and chronic sodium oxalate infusion

The purpose of this pilot study was to develop and characterize an in vivo porcine model of hyperoxaluria using intravenous infusion of sodium oxalate (NaOx). Two experimental regimens were developed to replicate acute and follow up chronic hyperoxaluria. In the acute model, 3 different doses of 1% NaOx were administered over 15 h, resulting in a dose-dependent increase in plasma oxalate concentra

Predicting response to enzalutamide and abiraterone in metastatic prostate cancer using whole-omics machine learning

Response to androgen receptor signaling inhibitors (ARSI) varies widely in metastatic castration resistant prostate cancer (mCRPC). To improve treatment guidance, biomarkers are needed. We use whole-genomics (WGS; n = 155) with matching whole-transcriptomics (WTS; n = 113) from biopsies of ARSI-treated mCRPC patients for unbiased discovery of biomarkers and development of machine learning-based pr

Intrinsic Molecular Subtypes of Metastatic Castration-Resistant Prostate Cancer

PURPOSE: Although numerous biology-driven subtypes have been described previously in metastatic castration-resistant prostate cancer (mCRPC), unsupervised molecular subtyping based on gene expression has been less studied, especially using large cohorts. Thus, we sought to identify the intrinsic molecular subtypes of mCRPC and assess molecular and clinical correlates in the largest combined cohort

The risk of revision using tourniquet or not in primary total knee replacement : an observational study from the Swedish Knee Arthroplasty Register

Background and purpose —The use of a tourniquet in knee replacement surgery is debated. Given the conflicting evidence, we aimed to compare the risk of revision after total knee replacements (TKR) with or without the use of tourniquet. Methods — In this register based observational study, we included the 5 most common cemented primary TKR models due to osteoarthritis reported to the Swedish Arthro

IL-1β expression driven by androgen receptor absence or inactivation promotes prostate cancer bone metastasis

We report the inverse association between the expression of androgen receptor (AR) and interleukin-1beta (IL-1β) in a cohort of patients with metastatic castration resistant prostate cancer (mCRPC). We also discovered that AR represses the IL-1β gene by binding an androgen response element (ARE) half-site located within the promoter, which explains the IL-1β expression in AR-negative (ARNEG) cance

Tilläggsstrukturer – meningar med kolon, tankstreck eller parentes – i svensk tidningstext

Meningsinterna skiljetecken – här kolon, tankstreck och parentes – används vanligtvis inte för att dela en sats i mindre delar, utan för att avgränsa satsexterna element från själva satsen. Den här studien utgår från dessa tre skiljetecken för att identifiera och kategorisera sådana element och de meningar de förekommer i, här kallade tilläggsstrukturer. Tilläggsstrukturer består av en initial ellSentence-internal punctuation marks – here the colon, dash and parenthesis – are not typically used to split a clause into smaller parts, but rather to delimit clause-external elements from the clause proper. This study uses these three punctuation marks as a starting point to identify and categorize such elements and the sentences containing them, here called supplement structures. Supplement str

A Lyapunov analysis of Korpelevich’s extragradient method with fast and flexible extensions

We develop a Lyapunov-based analysis of Korpelevich’s extragradient method and show that it achieves an o(1/k) last-iterate convergence rate of the constructed Lyapunov function. This Lyapunov function simultaneously upper bounds several standard measures of optimality, which allows our analysis to sharpen existing last-iterate convergence guarantees for these measures. Moreover, the same analysis

Sex- and country-specific associations of hyperuricemia and inflammation with vascular aging across populations with diverse cardiovascular risks

Introduction: The importance of measuring vascular age has been emphasized in numerous studies, highlighting its critical role in precision medicine. This cross-sectional heterogeneity exploration study examined sex- and country-specific association of serum uric acid (SUA) and inflammation, measured as high sensitivity C-reactive protein (hs-CRP), and vascular aging across populations with divers

Sex differences in the prevalence and risk factors for aortic valve calcification in the general population

Background Aortic valve calcification (AVC) is a disease process driven by inflammation and lipid infiltration, serving as a precursor to aortic stenosis. While male sex has been implicated as a risk factor for AVC, sex-specific differences, particularly among younger individuals in the general population, are not well characterised. Methods The Swedish CArdioPulmonary BioImage Study was used, com

The entrepreneurial region? Evolving regional government roles in bioeconomy governance

The downscaling of environmental responsibilities poses new challenges for regional governments, necessitating an evolution in their roles to manage environmental policy alongside traditional local development duties. This paper draws on the concept of the entrepreneurial state and on the idea of the ‘entrepreneurial region’ to explore how local and regional governments implement bioeconomy polici

ESR Essentials : Perfusion MRI—practice recommendations by the European Society for Magnetic Resonance in Medicine and Biology

Abstract: Perfusion MRI techniques—including dynamic susceptibility contrast (DSC) MRI, dynamic contrast-enhanced (DCE) MRI, arterial spin labeling (ASL) MRI, and intravoxel incoherent motion (IVIM) MRI—hold strong potential as imaging techniques for diagnosing, staging, and monitoring disease across a range of clinical applications. However, clinical adoption, especially of quantitative parameter

The Local Parastomal Hernia (LoPa) Repair : A Novel Approach to Parastomal Hernia Repair

Purpose: Surgical repair of parastomal hernias (PH) is challenging, mainly due to high recurrence rates. The Local Parastomal repair (LoPa) is a novel technique utilizing a retromuscular synthetic mesh with an outward-facing collar. This study describes the LoPa technique and evaluates its outcomes. Methods: This single-centre study retrospectively reviewed 39 consecutive patients who underwent Lo

När våldet läggs ut på entreprenad

Sweden has seen a rise of shootings and bombings, investigations of these crimes has shown that a sizable amount has been organised through Crime as a Service (CaaS), where serious violence is outsourced to relatively unconnected actors via anonymised and encrypted communication. Using a qualitative study design this thesis examines four Swedish court judgements involving CaaS and serious violence

Impaired cellular immune responses to herpes zoster subunit vaccine in patients with rheumatoid arthritis receiving Janus kinase inhibitors

Objective: To investigate cellular immune responses to the herpes zoster (HZ) subunit (HZ/su) vaccine in patients with rheumatoid arthritis (RA) treated with Janus kinase inhibitors (JAKis). Methods: RA patients treated with JAKi (n=46) at the Department of Rheumatology, Skåne University Hospital, Sweden, and healthy controls (n=37) received two doses of the HZ/su vaccine. Blood samples were colle

Optical and Microdialysis Monitoring of Succinate Prodrug Treatment in a Rotenone-Induced Model of Mitochondrial Dysfunction in Swine

Background/Objectives: Mitochondrial dysfunction is a major cause of brain injury in patients with primary mitochondrial disease. New mitochondrial therapeutics and non-invasive tools for efficacy monitoring are urgently needed. To these ends, succinate prodrug NV354 (methyl 3-[(2-acetylaminoethylthio)carbonyl]propionate) and diffuse optical techniques are promising. In this proof-of-concept study
