INTRODUCTION: There are few recent studies on trends over time in functional outcome and mortality after stroke, with results separately presented for ischaemic stroke (IS) or ICH. We aimed to determine temporal changes in functional outcome and case-fatality 90 days after IS and ICH in Sweden between 2010 and 2019. PATIENTS AND METHODS: We included patients (≥18 years) with first-ever IS or ICH r
octurnal lepidopteran pollinators face pesticide exposure risks in agricultural landscapes, yet lack adequate risk assessment frameworks compared to diurnal species. We present a formal model description for Noctua pronuba within the Animal Landscape and Man Simulation System (ALMaSS), providing the first comprehensive agent-based framework for assessing the impacts of pesticides on nocturnal mothNocturnal lepidopteran pollinators face pesticide exposure risks in agricultural landscapes, yet lack adequate risk assessment frameworks compared to diurnal species.

Background: Human immunodeficiency virus type 1 (HIV-1) is one of the fastest-evolving human pathogens. Understanding HIV-1 transmission, within-host adaptation, and evolutionary dynamics is pivotal for development of interventions and vaccines. HIV-1 infection is generally caused by a single transmitted founder virus (TFV), and TFV sequences are typically obtained using single genome amplificatio
AIMS/HYPOTHESIS: MicroRNAs are potential predictors and mediators of metabolic disease. Cystic fibrosis-related diabetes (CFRD) is the most common comorbidity in cystic fibrosis (CF). Here we aimed to investigate serum microRNAs in individuals with CF and differing glucose tolerance status. Specifically, we hypothesised that the circulating microRNA profile varies depending on glucose tolerance st
PURPOSE: To estimate the effect of dexamethasone eye drops on the risk of progression from type 2 retinopathy of prematurity (ROP) to ROP requiring traditional treatments.DESIGN: Register-based cohort study.PARTICIPANTS: Preterm infants born before 30 weeks' gestation from 2015-2018 (control years) and from 2020-2021 (intervention years) registered in the Swedish Quality Register for ROP at 4 Swed
Context. A growing number of white dwarfs (WDs) exhibit one or more signs of remnant planetary systems, including transits, infrared excesses, and atmospheric metal pollution. WD 1054-226 stands out for its unique, highly structured, and persistent photometric variability.Aims. We investigate the long-term stability and nature of the periodic signals observed in WD 1054-226 to better understand th
The fall armyworm, Spodoptera frugiperda, is becoming a serious invasive insect pest in Asia, Africa, and Oceania due to its broad spectrum of host plants and long flight distances. In response to the increasing risk of insecticide resistance, there is a growing need to develop more effective pest management options. One such option involves the use of synergists, which are substances that, while
The concentration of cholesterol in cell membranes affects membrane fluidity and thickness, and might regulate different processes such as the formation of lipid rafts. Since interpreting experimental data from biological membranes is rather intricate, investigations on simple models with biological relevance are necessary to understand the natural systems. We study the effect of cholesterol on th
The European Union has adopted targets for the expanded use of renewable energies (REs) as one mean to achieve improved energy security, reduced greenhouse gas (GHG) emissions, and improved competitiveness of the European economies. Realising that rapid expansion of RE will not happen in the energy market place, as it now exists, various support mechanisms are under consideration, most prominently
In fish of the Squalius alburnoides complex, hybridisation and polyploidy have affected sex ratios, resulting in strong correlations between sex and genotype. The preponderance of females among triploids and the occurrence of an all male lineage among diploids seem to imply that sex ratio deviations should have a strong genetic basis. Until now, no information has been gathered regarding the molec
Objectives: We evaluated a method for gas monitoring in the mastoid cavity using tunable diode laser spectroscopy by comparing it to simultaneously obtained computed tomographic (CT) scans. Methods: The presented optical technique measures free gases, oxygen (O2), and water vapor (H2O) within human tissue by use of low-power diode lasers. Laser light was sent into the tip of the mastoid process
Popular Abstract in Swedish HIV är en av de dödligaste farsoterna i världen och 30-40 miljoner människor beräknas ha dött AIDS. Genom att konstant förändra sig ligger viruset hela tiden ett steg före immunförsvaret, och immunförsvaret klarar därför inte av att bekämpa infektionen. HIV skiljer sig också från andra virus genom att det drabbar och långsamt utplånar immunförsvaret. Det gör att HIV kanThe two genetically related human lentiviruses known today, HIV-1 (which is pandemic) and HIV-2 (which mainly is confined to West Africa), are the causative agents of AIDS. Progressive immune dysfunction and AIDS develop in most cases of untreated HIV-1 infection, but only in approximately 25-30% of HIV-2 infected individuals. The V1-V3 region of the HIV-1 env gp120 is important for HIV-1 corecept
Popular Abstract in Swedish Stroke, eller slaganfall, är en sammanfattande benämning på sjukdomar som drabbar blodförsörjningen i hjärnan. Varje år insjuknar cirka 30000 personer i Sverige i stroke, av dessa drabbas cirka 15% av blödningar medan resterande 85% får infarkter, dvs blodpropp i hjärnan. Stroke upptar fler vårddagar i slutenvården än någon annan somatisk sjukdom. Medianåldern för insjuBackground Stroke is a serious vascular disorder that comprises intracerebral hemorrhages, subarachnoid hemorrhages and ischemic stroke (IS). The etiology of stroke, including hereditary components induced by cellular mechanisms, is therefore a research field of vital importance. The aim of this thesis was to assess possible genetic impact on stroke risk. We thus evaluated family history of strok
BackgroundIron deficiency is a common and undertreated problem in inflammatory bowel disease (IBD). AimTo develop an online tool to support treatment choice at the patient-specific level. MethodsUsing the RAND/UCLA Appropriateness Method (RUAM), a European expert panel assessed the appropriateness of treatment regimens for a variety of clinical scenarios in patients with non-anaemic iron deficienc
Binding of human immunoglobulin-G (IgG) from aqueous solutions and human plasma to concanavalin A (Con A) immobilized poly(acrylamide-allyl glycidyl ether) [poly(AAm-AGE)] monolithic cryogel has been studied. Poly(AAm-AGE) cryogel was prepared by bulk polymerization which proceeds in aqueous solution of monomers frozen inside a column (cryo-polymerization). After thawing, the monolithic cryogel co
Ethanol production from lignocellulose has great potential and is an important step in changing fuel consumption to a more environmentally friendly alternative. Lignocellulose is a large source of biomass. However, with lignocellulose and softwood lingocellulose in particular, high conversion of cellulose into fermentable sugars requires large amounts of enzymes. Addition of surfactants is known t
Cooking over open fire with solid fuels results in incomplete combustion and indoor air pollution (IAP) causing respiratory and other diseases leading to nearly two million premature deaths per year. In urban areas, IAP interacts with outdoor pollutants in toxic chemical mixtures affecting also other citizens and damaging regional air quality in terms of 'brown clouds'. Deaths result mainly in wom
The osteoclast is vital for establishment of normal hematopoiesis in the developing animal. However, its role for maintenance of hematopoiesis in adulthood is more controversial. To shed more light on this process, we transplanted hematopoietic stem cells from two osteopetrotic mouse models, with lack of osteoclasts or defective osteoclast function, to normal adult mice and examined the bone pheno
Submerged macrophytes play a key role in the functioning of stream ecosystems since they strongly affect the biological and physical environment of the habitat. On the other hand, flow velocity may affect growth and establishment of submerged macrophytes in streams and rivers. However, little attention has been paid to the morphological responses of submerged macrophytes to different stream flows
Co-production of high-value biobased products in biorefineries is a promising option for optimized utilization of biomass. Lignocellulosic materials such as agricultural and forest residues have been identified as attractive alternative feedstocks because of their high availability and low resource demand. This study assessed the greenhouse gas (GHG) performance and energy balance of ethanol co-pr
