Black carbon (BC) is produced by incomplete combustion of biomass and fossil fuels and is released as aerosols to the atmosphere with effects on the climate, environment, and human health. Current BC emissions are well monitored in many parts of the world. However, the geographical coverage is limited, and historical records of BC accumulation are still scarce. Here we present a quantification of

This work presents an alternative cetane rating method using a production compression ignition (CI) engine, offering an accessible approach for preliminary fuel evaluation without the need for specialized equipment. As part of this work, an empirical correlation was developed linking ignition delay (ID) to both the cetane number (CN) and intake oxygen concentration. The test method follows the pri

BackgroundThe captive bolt gun is a tool for stunning animals in the meat industry and is not considered a firearm under the Swedish firearm legislation. This study aimed to explore the involvement of such devices in human fatalities, with an emphasis on suicides. Epidemiological characteristics from a longitudinal perspective, as well as risk factors and injury patterns were analyzed.MethodSuicid

Background: Prolonged time to surgery (TTS) after neoadjuvant chemoradiotherapy (nCRT) may enable malnourished oesophageal cancer patients' nutritional status to recover better, possibly improving outcomes with fewer complications and better overall survival (OS) after oesophagectomy. Methods: This is a substudy within a multicentre randomised controlled trial comparing outcomes in patients with o

The efficiency and stability of wide bandgap (WBG) perovskite solar cells (PSCs) are constrained by photo-induced halide segregation and severe non-radiative recombination, which significantly impedes the advancement of high-efficiency and stable perovskite/silicon tandem solar cells (PSTSCs). In this work, a potassium 4-sulfonic-1,8-naphthalic anhydride salt (4S-NAPS), featuring dual-anchoring si

Purpose: This study aimed to evaluate the ability of a thigh-worn accelerometer to detect walking during daily life in individuals with Lumbar Spinal Stenosis (LSS). Two hypotheses were made regarding how walking measurements from the accelerometer, a walking test, and an ankle-worn StepWatch would relate in order for the accelerometer to be valid. The hypotheses were: (a) there is no difference b

Biomass gasification gas (BGG), a carbon-neutral renewable fuel and important hydrogen carrier, holds significant promise for sustainable energy systems. However, its practical implementation is challenged by combustion instability and elevated NOx emissions, primarily due to localized high-temperature zones induced by the hydrogen content. MILD (Moderate or Intense Low-oxygen Dilution) combustion

The design of iron complexes with long-lived charge transfer states suitable for applications as photosensitizers remains a formidable challenge. Here, we investigated the effect of an extended ligand π-system on the ground- and excited-state properties of iron(II) complexes with N-heterocyclic carbene (NHC) ligands. For this purpose, three iron complexes based on the established [Fe(II)(pbmi)2]2+

Objectives Early detection of neurosensory injury among workers exposed to hand-arm vibration is crucial. The aim of our study was to evaluate the diagnostic test performance of clinical point-of-care testing using a tuning fork and temperature rollers in relation to vibrotactile and thermal quantitative sensory testing. Methods We recruited 225 vibration-exposed workers who underwent clinical poi

Disinhibition of the mechanistic target of rapamycin (mTOR) pathway has been observed in patients with loss-of-function variants in the disheveled, Egl-10, and pleckstrin domain-containing protein 5 (DEPDC5), and nitrogen permease regulator-like proteins 2 and 3 (NPRL2, and NPRL3) genes, which encode the components of GTPase activating protein Activity Toward Rags Complex 1 (GATOR1) complex. Evero

IntroductionWhile smoking has been consistently identified as a significant contributor to postoperative complications, the existing literature on its association with postoperative pulmonary complications remains conflicting.AimWe examined the association of preoperative smoking with the occurrence of postoperative pulmonary complications (PPCs).MethodsPost hoc analysis of an observational study

BackgroundPreliminary results from the SNAP trial presented at ESCMID Global 2025 reported a high incidence (19.8%) of acute kidney injury (AKI) in patients treated with (flu)cloxacillin for Staphylococcus aureus bacteraemia (SAB).ObjectiveIn Sweden, cloxacillin is used at lower daily doses, and the risk of nephrotoxicity has not been assessed in this setting.MethodsWe retrospectively evaluated re

Background. The aim of this study was to provide an overview of age, sex and primary renal disease (PRD) distribution among first kidney transplant recipients across Europe. Method. The European Renal Association (ERA) Registry database was used to obtain data on patients aged 20 years or older receiving their first kidney transplant between 2010 and 2019 from 12 European countries. The numbers an

Objective: Women with current or previous drug use (WCPDU) have an increased risk of poor cervical and breast cancer outcomes, and low participation in screening for these cancer forms. The aim of this study was to assess self-reported barriers to and facilitators of cervical and breast cancer screening, among WCPDU. Methods: A survey based on results from a previous qualitative study about WCPDUs

Medication can affect the gut microbiota composition and function. The aim of this study was to investigate connections between use of common non-antibiotic medicines and the gut microbiota composition and function in a large Swedish cohort (N = 2223). Use of 67 medications and polypharmacy (≥ 5 medications), based on self-reported and prescription registry data, were associated with the relative

Purpose: Pancreatic ductal adenocarcinoma (PDAC) can be classified into distinct histological subtypes based on the WHO nomenclature. The aim of this study was to compare the prognosis of conventional PDAC (cPDAC) against the other histological variants at the population level. Methods: The Surveillance, Epidemiology and End Results (SEER) database was used to identify patients with microscopicall

Background: There is a current fashion for the use of methacrylate-containing nail cosmetics that can induce allergic contact dermatitis. European Union (EU) legislation was introduced in 2021 that had the aim of preventing its development. Objectives: To assess prevalence and exposures causing contact allergy to 2-hydroxyethyl methacrylate (HEMA) prior to and following implementation of the legis
