Severity and multiplicity of microvascular complications are associated with QT interval prolongation in patients with type 2 diabetes
AIMS/INTRODUCTION: A prolonged QT interval plays a causal role in life-threatening arrhythmia and becomes a risk factor for sudden cardiac death. Here, we assessed the association between microvascular complications and the QT interval in patients with type 2 diabetes.MATERIALS AND METHODS: Patients with type 2 diabetes (n = 219) admitted to our hospital for glycemic control were enrolled. QT inte

Household installation of solar panels – Motives and barriers in a 10-year perspective
This article compares what homeowners identified as motives and barriers for installing photovoltaic panels in Sweden in 2008–2009 and in 2014–2016. Earlier research has provided snapshots of existing barriers and motives, but not analyzed changes over time, as is done here. Between 2008 and 2014, the PV market in Sweden changed profoundly, with the introduction of subsidies and changes in rules,
Composition and sources of carbonaceous aerosols in Northern Europe during winter
Sources of elemental carbon (EC) and organic carbon (OC) in atmospheric aerosols (carbonaceous aerosols) were investigated by collection of weekly aerosol filter samples at six background sites in Northern Europe (Birkenes, Norway; Vavihill, Sweden; Risoe, Denmark; Cabauw and Rotterdam in The Netherlands; Melpitz, Germany) during winter 2013. Analysis of 14C and a set of molecular tracers were use
Diode laser-based thermometry using two-line atomic fluorescence of indium and gallium
A robust and relatively compact calibration-free thermometric technique using diode lasers two-line atomic fluorescence (TLAF) for reactive flows at atmospheric pressures is investigated. TLAF temperature measurements were conducted using indium and, for the first time, gallium atoms as temperature markers. The temperature was measured in a multi-jet burner running methane/air flames providing var
A two-level directional model for dependence in circular data
We present a likelihood-based test for clustering among sub-population mean directions for circular data. The test is based on a two-level hierarchical model with von Mises distributed variation on each level. The properties of the tests are investigated and compared to the commonly applied techniques of second-order analysis and pseudo-pooling of directions for the situation at hand. Finally we a
Visualization of lipid directed dynamics of perilipin 1 in human primary adipocytes
Perilipin 1 is a lipid droplet coating protein known to regulate lipid metabolism in adipocytes by serving as a physical barrier as well as a recruitment site for lipases to the lipid droplet. Phosphorylation of perilipin 1 by protein kinase A rapidly initiates lipolysis, but the detailed mechanism on how perilipin 1 controls lipolysis is unknown. Here, we identify specific lipid binding propertie
Predictors of Liver Fat and Stiffness in Non-Alcoholic Fatty Liver Disease (NAFLD) - An 11-Year Prospective Study
Liver fat can be non-invasively measured by proton magnetic resonance spectroscopy (1H-MRS) and fibrosis estimated as stiffness using transient elastography (FibroScan). There are no longitudinal data on changes in liver fat in Europids or on predictors of liver stiffness using these methods. We determined liver fat (1H-MRS) and clinical characteristics including features of insulin resistance at
Mueilha rare metals granite, Eastern Desert of Egypt : An example of a magmatic-hydrothermal system in the Arabian-Nubian Shield
The Mueilha granite pluton is one of the rare-metals bearing peraluminous granitic plutons in the Arabian-Nubian Shield. It represents the apical part of a highly evolved magma chamber emplaced at a shallow level subsequent to the post Pan-African orogeny. The pluton can be seen as a highly leucocratic medium-grained albite/oligoclase framework infilled with quartz, K-feldspar and muscovite that a
Injection of high dose botulinum-toxin A leads to impaired skeletal muscle function and damage of the fibrilar and non-fibrilar structures
Botulinum-toxin A (BoNT/A) is used for a wide range of conditions. Intramuscular administration of BoNT/A inhibits the release of acetylcholine at the neuromuscular junction from presynaptic motor neurons causing muscle-paralysis. The aim of the present study was to investigate the effect of high dose intramuscular BoNT/A injections (6 UI = 60 pg) on muscle tissue. The gait pattern of the rats was
Repulsion in Low Temperature β-Ensembles
We prove a result on separation of particles in a two-dimensional Coulomb plasma, which holds provided that the inverse temperature (Formula presented.) satisfies (Formula presented.). For large (Formula presented.), separation is obtained at the same scale as the conjectural Abrikosov lattice optimal separation.
Compact single-shot d-scan setup for the characterization of few-cycle laser pulses
We present a compact implementation of the ultrashort pulse measurement technique based on dispersion scans (d-scan), allowing single-shot measurement of few-cycle pulses. The main novelty in our design, making our setup extremely compact and simple, is the use, after a prism, of a spherical mirror in an off-axis geometry. The intentionally introduced strong astigmatism makes it possible to image
Supercapacitive Biosolar Cell Driven by Direct Electron Transfer between Photosynthetic Membranes and CNT Networks with Enhanced Performance
Integrating photosynthetic cell components with nanostructured materials can facilitate the conversion of solar energy into electric power for creating sustainable carbon-neutral energy sources. With the aim at exploring efficient photoinduced biocatalytic energy conversion systems, we have used an amidated carbon nanotube (aCNT) networked matrix to integrate thylakoid membranes (TMs) for construc

Molecular Simulations of Melittin-Induced Membrane Pores
Membrane-active peptides (MAPs) are able to induce pores in cell membranes via molecular mechanisms, which are still subject to ongoing research. In this work, we present molecular dynamics simulations that suggest a precursor membrane defect plays an important role in the pore-inducing activity of the prototypical antimicrobial peptide melittin. The simulations reveal that the hydrophobic N-termi
Nutrient limitations to bacterial and fungal growth during cellulose decomposition in tropical forest soils
Nutrients constrain the soil carbon cycle in tropical forests, but we lack knowledge on how these constraints vary within the soil microbial community. Here, we used in situ fertilization in a montane tropical forest and in two lowland tropical forests on contrasting soil types to test the principal hypothesis that there are different nutrient constraints to different groups of microorganisms duri
Why do horseflies need polarization vision for host detection? Polarization helps tabanid flies to select sunlit dark host animals from the dark patches of the visual environment
Horseflies (Tabanidae) are polarotactic, being attracted to linearly polarized light when searching for water or host animals. Although it is well known that horseflies prefer sunlit dark and strongly polarizing hosts, the reason for this preference is unknown. According to our hypothesis, horseflies use their polarization sensitivity to look for targets with higher degrees of polarization in thei
