The Lysine Demethylase KDM5B Regulates Islet Function and Glucose Homeostasis

Aims: Posttranslational modifications of histones and transcription factors regulate gene expression and are implicated in beta-cell failure and diabetes. We have recently shown that preserving H3K27 and H3K4 methylation using the lysine demethylase inhibitor GSK-J4 reduces cytokine-induced destruction of beta-cells and improves beta-cell function. Here, we investigate the therapeutic potential of

Multi-modal and multiscale imaging approaches reveal novel cardiovascular pathophysiology in Drosophila melanogaster

Establishing connections between changes in linear DNA sequences and complex downstream mesoscopic pathology remains a major challenge in biology. Herein, we report a novel, multi-modal and multiscale imaging approach for comprehensive assessment of cardiovascular physiology in Drosophila melanogaster. We employed high-speed angiography, optical coherence tomography (OCT) and confocal microscopy t

Uncompromised MRI of knee cartilage while incorporating sensitive sodium MRI

Sodium imaging is able to assess changes in ion content, linked to glycosaminoglycan content, which is important to guide orthopeadic procedures such as articular cartilage repair. Sodium imaging is ideally performed using double tuned RF coils, to combine high resolution morphological imaging with biochemical information from sodium imaging to assess ion content. The proton image quality of such

Co-existing Notions of Research Quality: A Framework to Study Context-specific Understandings of Good Research

Notions of research quality are contextual in many respects: they vary between fields of research, between review contexts and between policy contexts. Yet, the role of these co-existing notions in research, and in research policy, is poorly understood. In this paper we offer a novel framework to study and understand research quality across three key dimensions. First, we distinguish between quali

Diffusion parameter correlations for PEFC gas diffusion layers considering the presence of a water-droplet

A polymer electrolyte fuel cell (PEFC) produces electrical energy according to the electrochemical reactions carried out inside the cell. During the energy conversion, water molecules are also produced at the cathode side, which affects the gas diffusion layer (GDL) diffusion parameters. The generated water-drops from the reaction may give partial or total blockage of the reactant gases and also m

The immune microenvironment of colorectal cancer - Relationship with survival, sidedness, and pre-diagnostic anthropometry

Colorectal cancer (CRC) is the third most common cancer worldwide. Increasing evidence suggests that CRC should be considered a heterogeneous disease, with multiple differences between proximal and distal tumours. The immune system may, depending on the context, promote or inhibit tumour growth, and different immune cell subsets have been found to be associated with impaired or improved prognosis

Probiotics for intestinal decolonization of ESBL-producing enterobacteriaceae; a randomized, placebo-controlled clinical trial

OBJECTIVES: Infections with extended spectrum beta-lactamase (ESBL) producing Enterobacteriaceae (EPE) are a major healthcare concern. Our goal was to investigate whether a probiotic mixture could be used for eradication therapy in patients with prolonged intestinal EPE carriage.METHODS: We performed a randomized, placebo-controlled single blinded clinical superiority trial in the south of Sweden

More Power to the People: Electricity Adoption, Technological Change and Social Conflict

There is a wide-spread concern that technical change may spur social conflicts, especially if workers are replaced with machines. To empirically analyze whether job destruction drives protests, we study a historical example of a revolutionary new technology: the adoption of electricity. Focusing on the gradual roll-out of the Swedish electricity grid between 1900 and 1920 enables us to analyze 2,4

”We were only managing our legacy” Forms of agency in Olofström’s development path from supply chain to regional cluster

The labour market region of Olofström-Karlshamn experienced a period of exceptional economic decline between 2007 and 2010, prompted primarily by the job loss that resulted from restructuring within Volvo. In December 2008 around 1000 jobs disappeared overnight, throwing the municipality of 15000 people into crisis, and further rippling through the region. This is a story of a peripheral region de

A latent core of dark traits explains individual differences in peacekeepers’ unethical attitudes and conduct

The influence of military members’ malevolent personality traits on their ethical attitudes and behaviors has been the subject of research for decades. We investigated the relationship between malevolent individual difference factors (Machiavellianism, narcissism, psychopathy, the dominance facet of social dominance orientation, and right-wing authoritarianism) and aspects of military ethics befor

Early-onset pancreatic cancer : a population-based study using the SEER registry

Background: Early-onset pancreatic cancer (< 50 years, EOPC) is uncommon and limited data exist on clinical presentation and long-term survival. The aim of this study was to compare outcomes between patients with EOPC and those with later-onset pancreatic cancer (≥ 50 years, LOPC) using a large population-based cohort. Methods: The Surveillance, Epidemiology, and End Results (SEER) database was qu

Pressure-driven release of viral genome into a host nucleus is a mechanism leading to herpes infection

Many viruses previously have been shown to have pressurized genomes inside their viral protein shell, termed the capsid. This pressure results from the tight confinement of negatively charged viral nucleic acids inside the capsid. However, the relevance of capsid pressure to viral infection has not been demonstrated. In this work, we show that the internal DNA pressure of tens of atmospheres insid

Observation of Light-by-Light Scattering in Ultraperipheral Pb+Pb Collisions with the ATLAS Detector

This Letter describes the observation of the light-by-light scattering process, γγ→γγ, in Pb+Pb collisions at sqrt[s_{NN}]=5.02 TeV. The analysis is conducted using a data sample corresponding to an integrated luminosity of 1.73 nb^{-1}, collected in November 2018 by the ATLAS experiment at the LHC. Light-by-light scattering candidates are selected in events with two photons produced exclusively,

Raptor vision

Diurnal raptors (birds of the orders Accipitriformes and Falconiformes), renowned for their extraordinarily sharp eyesight, have fascinated humans for centuries. The high visual acuity in some raptor species is possible due to their large eyes, both in relative and absolute terms, and a high density of cone photoreceptors. Some large raptors, such as wedge-tailed eagles and the Old World vultures,

Genome-wide association meta-analyses and fine-mapping elucidate pathways influencing albuminuria

Increased levels of the urinary albumin-to-creatinine ratio (UACR) are associated with higher risk of kidney disease progression and cardiovascular events, but underlying mechanisms are incompletely understood. Here, we conduct trans-ethnic (n = 564,257) and European-ancestry specific meta-analyses of genome-wide association studies of UACR, including ancestry- and diabetes-specific analyses, and

Effects of lactobacillus plantarum and lactobacillus paracasei on the peripheral immune response in children with celiac disease autoimmunity : A randomized, double-blind, placebo-controlled clinical trial

Two Lactobacillus strains have proven anti-inflammatory properties by reducing pro-inflammatory responses to antigens. This randomized double-blind placebo-controlled trial tested the hypothesis that L. plantarum HEAL9 and L. paracasei 8700:2 suppress ongoing celiac disease autoimmunity in genetically at risk children on a gluten-containing diet in a longitudinally screening study for celiac disea
