CK2 activity is required for the interaction of FGF14 with voltage-gated sodium channels and neuronal excitability
Recent data shows that fibroblast growth factor 14 (FGF14) binds to and controls the function of the voltage-gated sodium (Nav) channel with phenotypic outcomes on neuronal excitability. Mutations in the FGF14 gene in humans have been associated with brain disorders that are partially recapitulated in Fgf14(-/-) mice. Thus, signaling pathways that modulate the FGF14:Nav channel interaction may be
ESI-MS/MS and MALDI-IMS Localization Reveal Alterations in Phosphatidic Acid, Diacylglycerol, and DHA in Glioma Stem Cell Xenografts
Glioblastoma (GBM) is the most common adult primary brain tumor. Despite aggressive multimodal therapy, the survival of patients with GBM remains dismal. However, recent evidence has demonstrated the promise of bone marrow-derived mesenchymal stem cells (BM-hMSCs) as a therapeutic delivery vehicle for anti-glioma agents due to their ability to migrate or home to human gliomas. While several studie
Combined structural methods to characterize an oligomeric small heat shock protein Hsp21
Undersökning av Hsp21 med korslänknings-masspektrometriMänniskans kropp består av ungefär 30 trillioner celler och varje cell innehåller omkring 100 000 proteiner. Föreställ dig om kroppen vore jordklotet, varje vävnad ett land och varje cell en stad. Varje stad vore då konstant som Paris i rusningstrafiken. Trafiken vore helt galen hela tiden och väldigt känslig för även den minsta störning. CellSmall heat shock proteins (sHsps) are found in all organisms and evolved early in the history of life, prior to the divergence of the three domains of life (Archaea, Bacteria, and Eukarya). Their malfunction is connected to several different diseases in humans, such as Alzheimer’s and Parkinson’s disease. sHsps are especially abundant in plants, where most are highly upregulated as the first line

Reported normal values and weighted means for commonly used echocardiography pulsed Doppler and tissue Doppler measurements
Pulsed Doppler (PW) and tissue Doppler imaging (TDI) measurements are part of every echocardiography examination for evaluation of left ventricular (LV) diastolic function and filling pressure. The purpose of this study was to summarize published data on normal values for PW and TDI measurements. A PubMed search was performed on the 10th of October 2016 to identify relevant articles. Studies were
How does distance to urban centres influence necessity and opportunity-based firm start-ups?
This paper seeks to understand how distance to urban centres influences necessity and opportunity-based firm start-ups. The results show that closeness to urban centres is not necessarily beneficial for firm start-ups. On the contrary, regions further away from urban centres of any size experience more firm start-ups. One explanation of this result is that regions experience spatial protection fro
A model library for simulation and benchmarking of integrated urban wastewater systems
This paper presents a freely distributed, open-source toolbox to predict the behaviour of urban wastewater systems (UWS). The proposed library is used to develop a system-wide Benchmark Simulation Model (BSM-UWS) for evaluating (local/global) control strategies in urban wastewater systems (UWS). The set of models describe the dynamics of flow rates and major pollutants (COD, TSS, N and P) within t
Investigations of microwave stimulation of turbulent flames with implications to gas turbine combustors
Efficient and clean production of electrical energy and mechanical (shaft) energy for use in industrial and domestic applications, surface- and ground transportation and aero-propulsion is currently of significant general concern. Fossil fuels are mainly used for transportation and aero-propulsion, but also for power generation. Combustion of fossil fuels typically give rise to undesired emissions
Wholegrain oat diet changes the expression of genes associated with intestinal bile acid transport
Scope: The molecular mechanisms underlying the cholesterol-lowering properties of oats are only partly known. To study possible pathways involved, we investigated gene expressions in the liver and small intestine of mice fed oats. Method and results: Cholesterol and bile acids were analyzed in plasma and feces from LDL-receptor deficient (LDLr-/-) mice fed Western diet with wholegrain oats. A tran
Individual and joint effects of risk factors for onset widespread pain and obesity - a population-based prospective cohort study
BACKGROUND: Widespread musculoskeletal pain (WSP) and obesity frequently co-occur and may have shared risk factors. We aimed to investigate whether four dichotomized risk factors individually or jointly increase the risk for the onset of WSP and onset of obesity.METHODS: Persons aged 34-76 years in 2004 living in Ullensaker municipality, Norway, responded to questionnaires in 2004 and 2010 (n = 15
Mitochondrial and Chloroplast Stress Responses Are Modulated in Distinct Touch and Chemical Inhibition Phases
Previous studies have identified a range of transcription factors that modulate retrograde regulation of mitochondrial and chloroplast functions in Arabidopsis (Arabidopsis thaliana). However, the relative importance of these regulators and whether they act downstream of separate or overlapping signaling cascades is still unclear. Here, we demonstrate that multiple stress-related signaling pathway
Valence instability in the bulk and at the surface of the antiferromagnet SmRh2Si2
Using resonant angle-resolved photoemission spectroscopy and electron band-structure calculations, we explore the electronic structure and properties of Sm atoms at the surface and in the bulk of the antiferromagnet SmRh2Si2. We show that the Sm atoms reveal weak mixed-valent behavior both in the bulk and at the surface. Although trivalent 4f emission strongly dominates, a small divalent 4f signal
Majorana fermions in topological-insulator nanowires : From single superconducting nanowires to Josephson junctions
Signatures of Majorana-fermion bound states in one-dimensional topological-insulator (TI) nanowires with proximity-effect-induced superconductivity are studied. The phase diagram and energy spectra are calculated for single-TI nanowires, and it is shown that the nanowires can be in the topologically invariant phases of winding numbers W=0,±1, and ±2, corresponding to the cases with zero, one, and

Synthesis and Characterization of Cyclopentadithiophene Heterofulvenes : Design Tools for Light-Activated Processes
The development of new materials for solar-to-energy conversion should consider stability, ease of fabrication, and beneficial photophysical properties. In this context, a set of novel π-conjugated building blocks, with phospha- and arsaalkenes possessing a unique dithienyl annulated heterofulvenoid core, have been prepared as air- and moisture-stable sensitizers. These compounds unify electron-do
High Arctic summer warming tracked by increased Cassiope tetragona growth in the world’s northernmost polar desert
Rapid climate warming has resulted in shrub expansion, mainly of erect deciduous shrubs in the Low Arctic, but the more extreme, sparsely vegetated, cold and dry High Arctic is generally considered to remain resistant to such shrub expansion in the next decades. Dwarf shrub dendrochronology may reveal climatological causes of past changes in growth, but is hindered at many High Arctic sites by sho
