Probing the redox metabolism in the strictly anaerobic, extremely thermophilic, hydrogen-producing Caldicellulosiruptor saccharolyticus using amperometry

Changes in the redox metabolism in the anaerobic, extremely thermophilic, hydrogen-forming bacterium Caldicellulosiruptor saccharolyticus were probed for the first time in vivo using mediated amperometry with ferricyanide as a thermotolerant external mediator. Clear differences in the intracellular electron flow were observed when cells were supplied with different carbon sources. A higher electro

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

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
