Objectives There is a lack of knowledge about whether occupational exposures increase the risk of emphysema, especially in never-smokers. Our objective was to determine if occupational exposures are associated with emphysema and impaired diffusing capacity. Methods In the Swedish CArdioPulmonary bioImage Study (SCAPIS), persons from the general population aged 50–64 answered a questionnaire and un
Heart and lung transplantation remain the primary treatments for end-stage organ failure; yet organ shortages and ischemia-reperfusion injury (IRI) limit their success. Extended criteria donors (ECDs) have expanded the donor pool; however, prolonged cold ischemia times increase the risk of primary graft dysfunction (PGD). Static cold storage (SCS), the standard organ preservation method, is subopt
Background: Obstetrical anal sphincter injuries are complications of vaginal birth that have the potential to cause substantial maternal morbidity. Predicting these injuries might help to improve maternal care as well as antenatal counseling and patient education. Previous attempts to create prediction models have in many cases involved variables only known postpartum, which limits their use in an
Antibiotic persistence arises when a subset of cells in an otherwise susceptible bacterial population temporarily exhibits elevated tolerance to bactericidal antibiotics. While significant progress has been made in elucidating persister mechanisms, much of this research has focused on Gram-negative bacteria, and these findings are not always applicable to Gram-positive species. This study explores
Introduction: Extrauterine pregnancy (EP), represents a significant challenge in reproductive medicine, manifesting in approximately 2% of all pregnancies, primarily implanting within the fallopian tubes (95%). Surgery remains a cornerstone in the therapeutic options for ectopic pregnancies. The most common surgical approach at the moment is laparoscopy. However a relatively new surgical technique
Chronic obstructive pulmonary disease (COPD) and lung cancer (LC) are recognized as severe diseases of the lungs and are closely linked to cigarette smoking and environmental pollution and share common mechanisms such as oxidative stress, inflammation, matrix degradation, and airway remodeling. Epidermal growth factor receptor (EGFR), a transmembrane receptor featuring an extracellular ligand bind
Micro-LEDs have emerged as a hot research topic due to their potential for next-generation display and lighting applications, necessitating advanced characterization techniques to optimize their performance. This study demonstrates the advantage of cathodoluminescence in the scanning electron microscope to be a critical tool for the optical characterization of InGaN platelets with red quantum well
Introduction: Mycobacteria have a unique hydrophobic membrane with several lipid-enriched layers that are low in permeability, setting them apart from other bacteria. This complex structure, consisting of three distinct layers is crucial for cell growth, virulence, and providing a barrier to antibiotics. Previously, we identified a plectasin variant, NZX, which showed activity against Mycobacteriu
This study introduces a novel approach for synthesising a surface-imprinted polymer-ordered mesoporous silica adsorbent, known as SiO2@MIPs-CAPcr, with high selectivity for chloramphenicol (CAP) adsorption by employing an activator that was regenerated by electron atom transfer radical polymerisation (ARGET ATRP). Optimal synthesising conditions for SiO2@MIPs-CAPcr have been determined, including
Minimal Kitaev chains, composed of two quantum dots connected via a superconductor, have emerged as an attractive platform to realize Majorana bound states (MBSs). These excitations exist when the ground state is degenerate. The additional requirement of isolating the MBS wave functions further restricts the parameter space to discrete sweet spots. While scaling up to Kitaev chains with more than
The coherence factors of quasiparticles in a superconductor determine their properties, including transport as well as their susceptibility to electric fields. In this work, we propose a way to infer the local coherence factors using local transport to normal leads. Our method is based on measuring the local current through a lead as the coupling to a second one is varied; the shape of the current
Catalytic activity is improved by reducing particle size, followed by atomic scale structural and chemical design, allowing physical and electronic confinement of chemical conversion centers. These concepts culminate in single-atom catalysts (SACs) where active precious metal atoms are isolated and anchored on the surface of supports and thus fully utilized for chemical conversion. In contrast, me
BACKGROUND: Chronic obstructive pulmonary disease (COPD) has many known dysregulated inflammatory proteins. A disintegrin and metalloproteinase 17 (ADAM17) is a protease that sheds several proteins involved in COPD pathogenesis. The aim was to investigate ADAM17, its phosphorylated form (pADAM17) and its substrates in bronchoalveolar lavage (BAL) and blood from COPD and control subjects. METHODS:
Lignin, a structurally intricate and heterogeneous phenolic biopolymer, holds considerable promise as a sustainable alternative to petrochemical-derived materials across diverse applications in the energy and materials sectors. However, precise lignin molecular weight and structure determination remains challenging due to its intrinsic tendency to aggregate in solution and the absence of chem
Investigation of the properties of membrane proteins (MPs) is essential to the successful development of medicines and biotechnology. However, their study is often complicated by denaturation caused by the use of detergents during conventional extraction methods. Copolymers of styrene and maleic acid (SMA) have shown promise in extracting MPs directly from cells while reconstituting lipid memb
Globally, road traffic accidents (RTAs) remain a major cause of death, particularly among individuals aged 15–30 years. While Sweden has been at the forefront of traffic safety through the Vision Zero initiative, in-hospital management remains crucial in determining RTA outcomes. Drawing on North American evidence suggesting improved survival at trauma centres, the Swedish healthcare system has in
Leptin is an adipocyte-secreted hormone, the circulating levels of which correlate closely with overall adiposity. Although rare mutations in the leptin (LEP) gene are well known to cause leptin deficiency and severe obesity, no common loci regulating circulating leptin levels have been uncovered. Therefore, we performed a genome-wide association study (GWAS) of circulating leptin levels from 32,1
Background When acute coronary syndrome (ACS) cannot be ruled out, emergency department (ED) patients with chest pain are admitted for in-hospital observation because of the risk of complications such as arrhythmia and acute heart failure. A study was undertaken to compare the ability of three risk prediction models to identify patients at a very low risk of complications. Methods 559 consecutive
Background: Earlier analyses within the EPIC study showed that dietary fibre intake was inversely associated with colorectal cancer risk, but results from some large cohort studies do not support this finding. We explored whether the association remained after longer follow-up with a near threefold increase in colorectal cancer cases, and if the association varied by gender and tumour location. Me
