A major fraction of nitrogen (N) in boreal forest soils is found in organic forms associated with soil organic matter (SOM) and mineral particles. The capacity of ectomycorrhizal (ECM) fungal symbionts to access this N is debated, considering that these fungi have lost many of the genes for decomposing organic matter that were present in their saprotrophic ancestors. To gain a molecular-level unde
Soil organic matter (SOM) constitutes the largest terrestrial C pool. An emerging, untested, view is that oxidation and depolymerization of SOM by microorganisms promote the formation of SOM-mineral associations that is critical for SOM stabilization. To test this hypothesis, we performed laboratory-scale experiments involving one ectomycorrhizal and one saprotrophic fungus that represent the two
Boreal trees rely on their ectomycorrhizal fungal symbionts to acquire growth-limiting nutrients, such as nitrogen (N), which mainly occurs as proteins complexed in soil organic matter (SOM). The mechanisms for liberating this N are unclear as ectomycorrhizal fungi have lost many genes encoding lignocellulose-degrading enzymes present in their saprotrophic ancestors. We hypothesized that hydroxyl
Land-use changes, pollution and climate warming during the 20th century havecaused changes in biodiversity across the world. However, in many cases, the environmental drivers are poorly understood. To identify and rank the drivers currentlycausing broad-scale floristic changes in N Europe, we analysed data from two vascularplant surveys of 200 randomly selected 2.5 9 2.5 km grid-squares in Scania,
The objective of the present work is to, in a single material, combine a number of molecular design strategies that have proven successful in the preparation of high-performance anionexchange membranes (AEMs) for alkaline fuel cells. Hence, we here report on highly conductive and alkali-stable poly(phenylene oxide)s carrying flexible side chains attached via alkyl spacer units, where each side cha
Improving our understanding of the relationships between biodiversity and the delivery of ecosystem services is crucial for the development of sustainable agriculture. We introduce a novel framework that is based on the identification of indicator species for single or multiple ecosystem services across taxonomic groups based on indicator species analyses. We utilize multi-species community data (
The assessment of effects of anthropogenic disturbance on biodiversity (BD) and ecosystem services (ES) and their relationships are key priorities of the Intergovernmental Panel for Biodiversity and Ecosystem Services. Agricultural landscapes and their associated BD provide multiple ES and it is crucial to understand how relationships between ES and BD components change along gradients of landscap
In this study, effects of a dust hole and its location on the flow structure, endwall heat transfer and friction factor in a U bend channel used for a gas turbine blade tip cooling are numerically studied. The dust hole is placed on the endwall of a U bend at different locations. The U bend channel without dust hole is considered as Baseline. The Reynolds number ranges from 50,000 to 440,000. Resu
Chorea-acanthocytosis (ChAc), an autosomal recessive disorder, is associated with cognitive and behavioral abnormalities. Previous studies were focused around exploring the functional annotation of VPS13A gene in ChAc, whereas the genetic labyrinth underlying this disease and plausible drug targets were underexplored. In the present study, we have identified the pivotal genes and molecular pathway
Ferritin, the central iron storage protein, has attracted attention as a biomarker of severe COVID-19. Few studies have investigated regulators of iron metabolism in the context of COVID-19. The aim was to evaluate biomarkers for iron metabolism in the acute phase response to community-acquired pneumonia (CAP) caused by SARS-CoV-2 compared with CAP caused by bacteria or influenza virus in hospital
We present a method for estimating fossil fuel methane emissions using observations of methane and ethane, accounting for uncertainty in their emission ratio. The ethane:methane emission ratio is incorporated as a spatially and temporally variable parameter in a Bayesian model, with its own prior distribution and uncertainty. We find that using an emission ratio distribution mitigates bias from us
BackgroundWe aimed to fill the gaps of knowledge concerning incidence rates and temporal trend, clinical features and risk factors for death for M. morganii bloodstream infections in south Sweden.MethodsThis was an observational, population-based study including all patients with at least one blood culture positive for Morganella morganii between 2013-2023 in Skåne, south Sweden.ResultsA total of
Poor preoperative sleep quality and impaired sleep continuity may heighten acute postoperative pain intensity and increase analgesic consumption, with negative implications for recovery, mental and physical health. The main objective of the current review was to investigate the relationship between preoperative sleep disturbance and acute postoperative pain control. Four electronic databases were
Human chorionic gonadotropin (hCG), a glycoprotein produced in the placenta, is crucial for a healthy pregnancy. We investigated the relationship between hCG levels and adverse pregnancy outcomes. We conducted a systematic review including studies measuring hCG blood levels in the first or second trimester, reporting on any of the 12 predefined adverse pregnancy outcomes with logistic regression-a
Aim: Necrotising enterocolitis (NEC) is the dominating surgical emergency in preterm neonates. The aims were to investigate indications, surgical management and mortality for surgically treated neonates with NEC. Methods: Data were retrieved from the Swedish Neonatal Quality Register for Swedish neonates with surgically treated NEC from 1 January 2017 to 31 December 2021. Diagnosis was validated b
Anterior Uveitis (AU) is the inflammation of the anterior part of the eye, the iris and ciliary body and is strongly associated with HLA-B*27. We report AU exome sequencing results from eight independent cohorts consisting of 3,850 cases and 916,549 controls. We identify common genome-wide significant loci in HLA-B (OR = 3.37, p = 1.03e-196) and ERAP1 (OR = 0.86, p = 1.1e-08), and find IPMK (OR =
Background: People with late effects of polio (LEoP) may need rehabilitation to manage everyday life but knowledge of the benefits of interdisciplinary rehabilitation is limited.Objective: To evaluate changes in performance and satisfaction with performance of activities among people with LEoP following interdisciplinary rehabilitation.Methods: A pre-post retrospective study based on data on 102 p
