Positive intergenic feedback circuitry, involving EBF1 and FOXO1, orchestrates B-cell fate
Recent studies have identified a number of transcriptional regulators, including E2A, early B-cell factor 1 (EBF1), FOXO1, and paired box gene 5 (PAX5), that promote early B-cell development. However, how this ensemble of regulators mechanistically promotes B-cell fate remains poorly understood. Here we demonstrate that B-cell development in FOXO1-deficient mice is arrested in the common lymphoid
HTT-lowering reverses Huntington's disease immune dysfunction caused by NF kappa B pathway dysregulation
Huntington's disease is an inherited neurodegenerative disorder caused by a CAG repeat expansion in the huntingtin gene. The peripheral innate immune system contributes to Huntington's disease pathogenesis and has been targeted successfully to modulate disease progression, but mechanistic understanding relating this to mutant huntingtin expression in immune cells has been lacking. Here we demonstr
The ESS Elliptical Cavity Cryomodules
The European Spallation Source (ESS) is a multi-disciplinary research centre under design and construction in Lund, Sweden. This new facility is funded by a collaboration of 17 European countries and is expected to be up to 30 times brighter than today's leading facilities and neutron sources. The ESS will enable new opportunities for researchers in the fields of life sciences, energy, environment
Cationic and anionic lipid-based nanoparticles in CEC for protein separation.
The development of new separation techniques is an important task in protein science. Herein, we describe how anionic and cationic lipid-based liquid crystalline nanoparticles can be used for protein separation. The potential of the suggested separation methods is demonstrated on green fluorescent protein (GFP) samples for future use on more complex samples. Three different CEC-LIF approaches for
Input/Output Stabilization in the General Two-Sided Model Matching Setup
The problem of input-output stabilization in a general two-sided model matching setup is studied. As a first step, the problem is reduced to a pair of uncoupled bilateral Diophantine equations over RH infinity. Then, recent results on bilateral Diophantine equations are exploited to obtain a numerically tractable solution given in terms of explicit state-space formulae. The resulting solvability c
Computationally Efficient Capon- and APES-based Coherence Spectrum Estimation
The coherence spectrum is of notable interest as a bivariate spectral measure in a variety of application, and the topic has lately attracted interest with the recent formulation of several ligh-resolution data adaptive estimators. In this work, we further this development with the presentation of computationally efficient implementations of the Caponand APE S-based MSC estimators. The presented i
Classification of Raman Spectra to Detect Hidden Explosives
Raman spectroscopy is a laser-based vibrational technique that can provide spectral signatures unique to a multitude of compounds. The technique is gaining widespread interest as a method for detecting hidden explosives due to its sensitivity and ease of use. In this letter, we present a computationally efficient classification scheme for accurate standoff identification of several common explosiv
Performing work: The drama of everyday working life
Abstract in UndeterminedIn this article, a perspective on work time patterns is outlined; a perspective that emphasizes the importance of observing how work time is subject not only to task and contract agreements but also to social norms and individual needs to express identity. The article takes its starting point in Goffman’s dramaturgic approach. From this perspective, the workplace is viewed
Biopsy findings in giant cell arteritis: relationship to baseline factors and corticosteroid treatment.
Flattening filter free beams in SBRT and IMRT: Dosimetric assessment of peripheral doses
Purpose: Recently, there has been a growing interest in operating medical linear accelerators without a flattening filter Due to reduced scatter, leaf transmission and radiation head leakage a reduction of out-of-field dose is expected for flattening filter free beams. The aim of the present study was to determine the impact of unflattened beams on peripheral dose for advanced treatment techniques
A consistent modelling methodology for secondary settling tanks: A reliable numerical method.
The consistent modelling methodology for secondary settling tanks (SSTs) leads to a partial differential equation (PDE) of nonlinear convection–diffusion type as a one-dimensional model for the solids concentration as a function of depth and time. This PDE includes a flux that depends discontinuously on spatial position modelling hindered settling and bulk flows, a singular source term describing

Antioxidant secondary metabolites from Geranium lasiopus Boiss. & Heldr.
Chromatographic studies on the EtOAc soluble portion of the MeOH extract of Geranium lasiopus led to the isolation of eight flavonoids (kaempferol (1), quercetin (2), quercetin 3-O-beta-glucopyranoside (3), quercetin 3-O-beta-galactopyranoside (4), kaempferol 3-O-alpha-rhamnopyranosyl-(1 -> 6)-beta-glucopyranoside (5), quercetin 3-O-alpha-rhamnopyranosyl-(1 -> 6)-beta-glucopyranoside (6), kaempfer
Menstrual cycle characteristics in fertile women from Greenland, Poland and Ukraine exposed to perfluorinated chemicals: a cross-sectional study
Does perfluorooctane sulfonate (PFOS) and perfluorooctanate (PFOA) exposure disrupt the menstrual cyclicity? The female reproductive system may be sensitive to PFOA exposure, with longer menstrual cycle length at higher exposure. PFOS and PFOA are persistent man-made chemicals. Experimental animal studies suggest they are reproductive toxicants but epidemiological findings are inconsistent. A cros
CHEMOTHERAPY Current drugs still have potential in advanced ovarian cancer
Dose-dense administration of paclitaxel as well as intraperitoneal administration of platinum and paclitaxel as first-line treatments provide similar advantages compared with standard treatment in advanced ovarian cancer. Both approaches, however, need to be confirmed by additional studies. a low dose of pegylated liposomal doxorubicin combined with carboplatin is superior to standard paclitaxel a
Struggling for One's Name: Defense Narratives by those Accused of Small-Time Corruption
Under scrutiny (what we term a “bribery gaze”), many interpersonal exchanges in work contexts are perceived as bribes rather than gifts, tokens of appreciation, or mundane favors. Current Swedish bribery laws are strong, and the media keep a vigilant eye out for suspicious activities. From a wide set of qualitative data, we selected 13 interviews with formally-accused middle managers and low-level
ATLAS search for new phenomena in dijet mass and angular distributions using pp collisions at root s=7 TeV
Mass and angular distributions of dijets produced in LHC proton-proton collisions at a centre-of-mass energy root s = 7TeV have been studied with the ATLAS detector using the full 2011 data set with an integrated luminosity of 4.8 fb(-1). Dijet masses up to similar to 4.0TeV have been probed. No resonance-like features have been observed in the dijet mass spectrum, and all angular distributions ar
Dioxomolybdenum(VI) and -tungsten(VI) Complexes with Multidentate Aminobisphenol Ligands as Catalysts for Olefin Epoxidation
The synthesis of four molybdenum and tungsten complexes bearing tetradentate tripodal amino bisphenolate ligands with either hydroxyethylene (1a) or hydroxyglycolene (1b) substituents is reported. The molybdenum dioxo complexes [MoO2L] (L = 2a, 2b) and tungsten complexes [WO2L] (3a, 3b) were synthesized using [MoO2(acac)(2)] and [W(eg)(3)] (eg = 1,2-ethanediolato, ethylene glycolate), respectively
A genetic variant in osteoprotegerin is associated with progression of joint destruction in rheumatoid arthritis
Introduction: Progression of joint destruction in rheumatoid arthritis (RA) is partly heritably; 45 to 58% of the variance in joint destruction is estimated to be explained by genetic factors. The binding of RANKL (Receptor Activator for Nuclear Factor kappa B Ligand) to RANK results in the activation of TRAF6 (tumor necrosis factor (TNF) receptor associated factor-6), and osteoclast formation ult
