Characterisation of ground thermal and thermo-mechanical behaviour for shallow geothermal energy applications

Increasing use of the ground as a thermal reservoir is expected in the near future. Shallow geothermal energy (SGE) systems have proved to be sustainable alternative solutions for buildings and infrastructure conditioning in many areas across the globe in the past decades. Recently novel solutions, including energy geostructures, where SGE systems are coupled with foundation heat exchangers, have

T regulatory cells and dendritic cells protect against transfusion-related acute lung injury via IL-10

Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related fatalities and is characterized by acute respiratory distress following blood transfusion. Donor antibodies are frequently involved; however, the pathogenesis and protective mechanisms in the recipient are poorly understood, and specific therapies are lacking. Using newly developed murine TRALI models based o

The SlZRT1 gene encodes a Plasma membrane-located ZIP (Zrt-, Irt-Like Protein) transporter in the ectomycorrhizal fungus Suillus luteus

Zinc (Zn) is an essential micronutrient but may become toxic when present in excess. In Zn-contaminated environments, trees can be protected from Zn toxicity by their root-associated micro-organisms, in particular ectomycorrhizal fungi. The mechanisms of cellular Zn homeostasis in ectomycorrhizal fungi and their contribution to the host tree's Zn status are however not yet fully understood. The ai

Utvärdering av utrymningsbelysning i vägtunnlar

I svenska vägtunnlars trafikutrymme ska det finnas utrymningsbelysningsarmaturer i form av vägledande utrymningsljus. För Trafikverkets vägtunnlar styrs utformningen av innehållet i SS-EN 16276:2013 om utrymningsbelysning i vägtunnlar. I denna standard föreskrivs dock endast en minsta ljusstyrka (motsvarande 1 candela i alla riktningar som de kan ses från en utrymmande person), vilket är ett mycke

Ländryggsröntgen ger falsk säkerhet och ringa nytta för patienten : MRT och DT ger bättre och billigare resultat

In 2016 140 000 lumbar spine radiographies were performed in Sweden (14 000 per million inhabitants) to a cost of about 85 million SEK (≈8.5 million Euro) and a negligible value for the patients with low back pain. In the work-up of low back pain, when imaging is indicated, lumbar spine radiography should be replaced by limited magnetic resonance imaging including a whole lower body coronal STIR s

Elevated Markers of Death Receptor-Activated Apoptosis are Associated with Increased Risk for Development of Diabetes and Cardiovascular Disease

Background An increased rate of cell death by apoptosis has been implicated in both diabetes and atherosclerosis. Apoptosis can be induced through activation of the death receptors TNF receptor 1 (TNFR-1), TRAIL receptor 2 (TRAILR-2) and Fas. Soluble forms of these receptors are found in plasma. The objective of this study was to determine if soluble death receptors are markers of receptor-activat

Optical projection tomography for rapid whole mouse brain imaging

In recent years, three-dimensional mesoscopic imaging has gained significant importance in life sciences for fundamental studies at the whole-organ level. In this manuscript, we present an optical projection tomography (OPT) method designed for imaging of the intact mouse brain. The system features an isotropic resolution of ~50 µm and an acquisition time of four to eight minutes, using a 3-day op

Mature murine megakaryocytes present antigen-MHC class I molecules to T cells and transfer them to platelets

Megakaryocytes (MKs) are bone marrow-derived cells that are primarily responsible for generating platelets for the maintenance of hemostasis. Although MK can variably express major histocompatibility complex (MHC) class I and II molecules during their differentiation, little is known whether they can elicit nonhemostatic immune functions such as T-cell activation. Here, we demonstrate that mature

Orai channels are critical for receptor-mediated endocytosis of albumin

Impaired albumin reabsorption by proximal tubular epithelial cells (PTECs) has been highlighted in diabetic nephropathy (DN), but little is known about the underlying molecular mechanisms. Here we find that ORAI1-3, are preferentially expressed in PTECs and downregulated in patients with DN. Hyperglycemia or blockade of insulin signaling reduces the expression of ORAI1-3. Inhibition of ORAI channe

A cognitive semiotics approach to the analysis of street art : The case of Athens

This paper is part of my ongoing doctoral research centered on “Street Art and Cognitive Semiotics: The case of Athens” at the division of Cognitive Semiotics at Lund University. More concretely, in this article, a fresh approach, based on a constructive (verbo-) pictorial argument, is taken to attending the relationship between a cognitive semiotics approach and street art signs in a programmatic

Cartilage oligomeric matrix protein promotes prostate cancer progression by enhancing invasion and disrupting intracellular calcium homeostasis

Cartilage oligomeric matrix protein (COMP) was recently implicated in the progression of breast cancer. Immunostaining of 342 prostate cancer specimens in tissue microarrays showed that COMP expression is not breast cancer-specific but also occurs in prostate cancer. The expression of COMP in prostate cancer cells correlated with a more aggressive disease with faster recurrence. Subcutaneous xenog
