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

Co-existence of multiple trade-off currencies shapes evolutionary outcomes

Evolutionary studies often assume that energy is the primary resource (i.e. “currency”) at the heart of the survival-reproduction trade-off, despite recent evidence to the contrary. The evolutionary consequences of having a single trade-off currency versus multiple competing currencies are unknown. Using simulations, we modeled the evolution of either a single physiological currency between reprod

Purification and functional comparison of nine human Aquaporins produced in Saccharomyces cerevisiae for the purpose of biophysical characterization

The sparse number of high-resolution human membrane protein structures severely restricts our comprehension of molecular physiology and ability to exploit rational drug design. In the search for a standardized, cheap and easily handled human membrane protein production platform, we thoroughly investigated the capacity of S. cerevisiae to deliver high yields of prime quality human AQPs, focusing on

Possibilities for maintaining a strong self - A grounded theory study of relational experiences among Thai women in Sweden

Background: Due to increasing globalization and Internet communication, the number of international marriages has increased. In Sweden, 75% of the Thai population are women, among whom 80% are partnered with Swedish or other Scandinavian men. Previous studies have indicated that lack of autonomy, social isolation, and stigma are important risk factors for poor mental health for foreign-born women

Compromise and avoidance : The response to new legislation

Purpose: The aim of this paper is to describe, analyze and explain the level of compliance of accounting practices with legislation and generally accepted accounting principles (GAAP) within the Swedish water and sewerage sector. Design/methodology/approach: The empirical data are based on a document study of the annual full cost accounting reports for the financial year 2010. Weobtained complete
