Manganese(II)- and nickel(II)-catalyzed oxidation of sulfur(IV) by oxygen in aqueous solution at pH 4.5 has been studied, as a model for oxidation of sulfur(IV) to sulfuric acid at the natural pH of the droplets in most atmospheric aqueous systems.

Human enteroviruses (HEV), especially coxsackievirus serotype B (CVB) and echovirus (E), have been associated with diseases of both the exocrine and endocrine pancreas, but so far evidence on HEV infection in human pancreas has been reported only in islets and ductal cells. This study aimed to investigate the capability of echovirus strains to infect human exocrine and endocrine pancreatic cells.

Background and purpose — The outcome of surgical treatment of lumbar disc herniation (LDH) has been thoroughly evaluated in middle-aged patients, but less so in elderly patients. Patients and methods — With validated patient-reported outcome measures (PROMs) and using SweSpine (the national Swedish Spine Surgery Register), we analyzed the preoperative clinical status of LDH patients and the 1-year

In a spatial simulation we show that formation of a stable, narrow hybrid zone requires no selection, only that individuals can recognize their own population type since this is a prerequisite for assortative mating. The European crow occurs in two species/subspecies that meet in a long hybrid zone, the black carrion crow Corvus corone and the grey and black hooded crow C. cornix. In a previous st

Arsenic, an established carcinogen and toxicant, occurs in drinking water and food and affects millions of people worldwide. Arsenic appears to interfere with gene expression through epigenetic processes, such as DNA methylation and post-translational histone modifications. We investigated the effects of arsenic on histone residues in vivo as well as in vitro. Analysis of H3K9Ac and H3K9me3 in CD4

The ambition to integrate disaster risk information from multiple stakeholders exists at different scales in any country and serve to control the risk of losses within companies, organizations and countries as a whole. Against the backdrop of extensive deliberations with risk management professionals in Sweden, this paper is based on an interdisciplinary scoping study of literature aimed to enhanc

Long-term right ventricular pacing is associated with left ventricular dysfunction and cardiomyopathy, particularly in pediatric patients and those with congenital heart disease (CHD). Research has shown that pacing-induced cardiomyopathy can be reversed with nonselective or selective His bundle pacing in adults, however, the information available about the use of this type of therapy in pediatric

Background: There are limited data on population-wide assessment of cost in Crohn's disease (CD) and ulcerative colitis (UC). Aim: To estimate the societal cost of actively treated CD and UC in Sweden. Methods: We identified 10 117 prevalent CD and 19 762 prevalent UC patients, aged ≥18 years on 1 January 2014 and 4028 adult incident CD cases and 8659 adult incident UC cases (2010-2013) from Swedi

Gardeners have always used plants of different origins, moving them around to new environments, working hard to make the plants survive and thrive under new conditions. Certain plant varieties have proved to be particularly vital, have a long history as cultivars, and are today understood as heritage plants. Many have spread over centuries and are today regarded as ‘belonging’ and as more or less Gardeners have always used plants of different origins, moving them around to new environments, working hard to make the plants survive and thrive under new conditions.

Silver nanoparticles (AgNPs) are commonly used in commercial and medical applications. However, AgNPs may induce toxicity, extracellular matrix (ECM) changes and inflammatory responses. Fibroblasts are key players in remodeling processes and major producers of the ECM. The aims of this study were to explore the effect of AgNPs on cell viability, both ex vivo in murine precision cut lung slices (PC

The effect of various antipsychotics during pregnancy has repeatedly been studied, but for most atypical antipsychotics, only little information is available. We identified from the Swedish Medical Birth Register 2908 women who had reported the use of any antipsychotic or lithium in early pregnancy and studied malformation rates with data also from the Register of Congenital Malformations and the

Recent research has identified promising targets for therapeutic interventions aimed at modulating the inflammatory response in sepsis. Herein, the authors describe mechanisms involved in the clearance of pathogen toxin from the circulation and potential interventions aimed at enhancing clearance mechanisms. The authors also describe advances in the understanding of the innate immune response as p

Popular Abstract in Swedish Den teoretiska beskrivningen av materians minsta beståndsdelar, den så kallade standardmodellen (SM), överenstämmer med oerhörd noggrannhet med de många och avancerade partikelfysik-experiment som utförts världen över. Trots denna överenstämmelse finns problematiska aspekter hos SM som gör att den inte kommer kunna beskriva fysikaliska fenomen vid högre energier, som änA search for new physics using events with a single photon and missing energy has been made at the DELPHI experiment together with a search for charginos. The results were based on data collected up to and including the final year of 2000. An integrated luminosity of 650 pb^-1 was used in the single photon analysis and 450 pb^-1 in the chargino search. Center-of-mass energies up to 209 GeV were ex

Popular Abstract in Swedish För många cancerpatienter är strålbehandling ett viktigt behandlingsalternativ. En framgångsrik behandling kräver att den absorberade dosen till patienten kan ges med stor noggrannhet. Detta eftersom en liten avvikelse i absorberad dos kan påverka behandlingens resultat. Strålbehandling sker idag med avancerad teknik och utrustning där osäkerheterna i varje led i behandThis thesis presents a new verification concept, the virtual accelerator, for dose calculation algorithms used in treatment planning systems (TPSs) for external beam radiotherapy. The algorithm input data required to implement a treatment unit in the TPS are generated by Monte Carlo simulations as are the beam reference data needed for the subsequent evaluation of the dose calculation algorithm. T

This paper verified the macro-to-mini-scale criterion BoRe10.5=200 because data points where BoRe10.5≤200 and BoRe10.5>200 show very different trends for the entire database (1672 data points). Boiling number at critical heat flux (Blchf) decreases greatly with heated length-to-diameter ratio (Lh/dhe) when Lh/dhe is small while a relatively smooth trend occurs with large Lh/dhe values. The paper p

The overall aim of this composite thesis, consisting of five articles, is to develop concepts for furthering the understanding of small business managers´ handling of finance. The main contribution is the development of a conceptual understanding of so-called financial bootstrapping behavior in small businesses (referring to the use of methods for minimizing and/or eliminating the need for financi
