The complement inhibitor factor H generates an anti-inflammatory and tolerogenic state in monocyte-derived dendritic cells

The activation of the complement system is a key initiating step in the protective innate immune-inflammatory response against injury, although it may also cause harm if left unchecked. The structurally related soluble complement inhibitors C4b-binding protein (C4BP) and factor H (FH) exert a tight regulation of the classical/lectin and alternative pathways of complement activation, respectively,

Combination of phage and Gram-positive bacterial display of human antibody repertoires enables isolation of functional high affinity binders

Surface display couples genotype with a surface exposed phenotype and thereby allows screening of gene-encoded protein libraries for desired characteristics. Of the various display systems available, phage display is by far the most popular, mainly thanks to its ability to harbour large size libraries. Here, we describe the first use of a Gram-positive bacterial host for display of a library of hu

Malmö treatment referral and intervention study—high 12-month retention rates in patients referred from syringe exchange to methadone or buprenorphine/ naloxone treatment

Background: Heroin dependence is associated with high mortality. Opioid agonist treatment (OAT) with methadone or buprenorphine has strong evidence for treatment of this relapsing condition. In our setting, OAT has been associated with strict and demanding intake procedures, often with requirements of social stability, but also high, approximately 80 percent 12-month retention rates. In a recent r

Distinct DC subsets regulate adaptive Th1 and 2 responses during Trichuris muris infection

Low- and high-dose infections with the murine large intestinal nematode Trichuris muris are associated with induction of adaptive Th1 and Th2 responses, respectively, in mesenteric lymph nodes (MLN). Classical dendritic cells (cDC) accumulate in the large intestinal mucosa and MLN upon T. muris infection, yet their role in driving adaptive responses to infection remains largely unknown. We perform

The Evolving Future of Instantaneous Wave-Free Ratio and Fractional Flow Reserve

In this review, the authors reflect upon the role of coronary physiology in the modern management of coronary artery disease. They critically appraise the scientific background of the instantaneous wave-free ratio (iFR) and fractional flow reserve (FFR), from early experimental studies to validation studies against indexes of ischemia, to clinical trials assessing outcome. At this important junctu

Lubricin binds cartilage proteins, cartilage oligomeric matrix protein, fibronectin and collagen II at the cartilage surface

Lubricin, a heavily O-glycosylated protein, is essential for boundary lubrication of articular cartilage. Strong surface adherence of lubricin is required given the extreme force it must withstand. Disulfide bound complexes of lubricin and cartilage oligomeric matrix protein (COMP) have recently been identified in arthritic synovial fluid suggesting they may be lost from the cartilage surface in o

Rum för reflektion : Om sjukrummet i det nordiska måleriet mot 1800-talets slut

This dissertation examines the intense presence of the encounter with a number of artworks depicting sickrooms painted by Nordic artists by the end of the nineteenth century. To understand the intense presence enhanced through the encounter with these artworks, this dissertation argues that these paintings can be understood and examined as secular devotional images. Particular attention is devoted

Allergen-specific human IgE isolated through an allergen-agnostic pipeline—understanding immune response and allergen recognition

Allergy, characterised by antibody responses of the IgE isotype, is a major health concern. The set of monoclonal human IgE used for studying the molecular mechanisms of allergies is limited. Single-cell sequencing offers opportunities to establish novel antibodies for researching, diagnosis, and treatment of allergies. We describe and exploit a pipeline for generating recombinant IgE directly fro

The Power of Flow Cytometry in the Cytopathologic Diagnosis of Lymphoid Lesions

Abstract – Background: Cytological examination of a fine-needle aspirate (FNA) is a minimally invasive modality that is increasingly used in the diagnosis of lymphoma. Flow cytometry and other ancillary tests make an important contribution to the diagnostic value of FNAs of lymphoid lesions. This review follows the recent publication of the first edition of the WHO Reporting System for Lymph Node,

Impaired Mitochondrial Function and Insulin Resistance of Skeletal Muscle in Mitochondrial Diabetes

OBJECTIVE - Impaired muscular mitochondrial function is related to common insulin resistance in type 2 diabetes. Mitochondrial diseases frequently lead to diabetes, which is mostly attributed to defective beta-cell mitochondria and secretion. RESEARCH DESIGN AND METHODS - We assessed muscular mitochondrial function and lipid deposition in liver (hepatocellular lipids [HCLs]) and muscle (intramyoce

Development and validation of an artificial neural network algorithm to predict mortality and admission to hospital for heart failure after myocardial infarction : a nationwide population-based study

Background: Patients have an estimated mortality of 15–20% within the first year following myocardial infarction and one in four patients who survive myocardial infarction will develop heart failure, severely reducing quality of life and increasing the risk of long-term mortality. We aimed to establish the accuracy of an artificial neural network (ANN) algorithm in predicting 1-year mortality and

Gene editing of CD34+ progenitor cells from single blood donor waste bags to create cultured early erythroid cells for study of blood group knock-outs

Background: Many blood group antigens are carried by red cell surface proteins, thefunctions of which are not yet fully characterized or in some cases completelyunknown. By investigating red cells with naturally-occurring blood group variants,much has been learnt about the underlying molecules. However, interindividualvariation affecting other molecules than the one(s) of interest may confound oro

Probing cosmology via the clustering of critical points

Exclusion zones in the cross-correlations between critical points (peak-void, peak-wall, filament-wall, and filament-void) of the density field define quasi-standard rulers that can be used to constrain dark matter and dark energy cosmological parameters. The average size of the exclusion zone is found to scale linearly with the typical distance between extrema. The latter changes as a function of

Multi-fidelity reduced-order surrogate modelling

High-fidelity numerical simulations of partial differential equations (PDEs) given a restricted computational budget can significantly limit the number of parameter configurations considered and/or time window evaluated. Multi-fidelity surrogate modelling aims to leverage less accurate, lower-fidelity models that are computationally inexpensive in order to enhance predictive accuracy when high-fid
