Effects of adalimumab treatment on endothelial cell activation markers in the skeletal muscle of patients with rheumatoid arthritis.

Patients with rheumatoid arthritis (RA), particularly those with severe disease, have increased risk of cardiovascular disease (CVD). Previous studies suggest that endothelial cell activation may contribute to this co-morbidity, and that treatment with tumour necrosis factor (TNF) inhibitors could reduce the risk of CVD in these patients. The aim of this study was to investigate endothelial cell a

The Emerging EU Peacebuilding Framework: Confirming or Transcending Liberal Peacebuilding

The EU is now emerging as a major actor in regional and global peacebuilding. The EU does not perceive conflict as endemic, and develops its policy on the basis that conflict is eminently resolvable if structural issues, needs, social injustice, and inequality are addressed. Yet its peacebuilding project is subject to some significant and familiar contradictions. We identify the basis for what may

Sensitizing capacity of Disperse Orange 1 and its potential metabolites from azo reduction and their cross-reactivity pattern.

Simultaneous contact allergies to Disperse Orange 1, 4-nitroaniline and p-aminodiphenylamine (PADPA), as well as to other disperse azo dyes and to p-phenylenediamine (PPD), have been reported. Cross-reactivity is one of the possible explanations for simultaneous reactions between PPD and disperse azo dyes. Some metabolites from the azo reduction of these disperse azo dyes could be sensitizers, as

The role of the sun in the celestial compass of dung beetles.

Recent research has focused on the different types of compass cues available to ball-rolling beetles for orientation, but little is known about the relative precision of each of these cues and how they interact. In this study, we find that the absolute orientation error of the celestial compass of the day-active dung beetle Scarabaeus lamarcki doubles from 16° at solar elevations below 60° to an e

Structure and Dynamics of a Compact State of a Multidomain Protein, the Mercuric Ion Reductase

The functional efficacy of colocalized, linked protein domains is dependent on linker flexibility and system compaction. However, the detailed characterization of these properties in aqueous solution presents an enduring challenge. Here, we employ a novel, to our knowledge, combination of complementary techniques, including small-angle neutron scattering, neutron spin-echo spectroscopy, and all-at

Structural dynamics of supercooled water from quasielastic neutron scattering and molecular simulations.

One of the outstanding challenges presented by liquid water is to understand how molecules can move on a picosecond time scale despite being incorporated in a three-dimensional network of relatively strong H-bonds. This challenge is exacerbated in the supercooled state, where the dramatic slowing down of structural dynamics is reminiscent of the, equally poorly understood, generic behavior of liqu

Evolution of multicomponent pheromone signals in small ermine moths involves a single fatty-acyl reductase gene

Fatty-acyl CoA reductases (FAR) convert fatty acids into fatty alcohols in pro- and eukaryotic organisms. In the Lepidoptera, members of the FAR gene family serve in the biosynthesis of sex pheromones involved in mate communication. We used a group of closely related species, the small ermine moths (Lepidoptera: Yponomeutidae) as a model to investigate the role of FARs in the biosynthesis of compl

Feasibility study of using a "travelling" CO2 and CH4 instrument to validate continuous in situ measurement stations

In the course of the ICOS (Integrated Carbon Observation System) Demonstration Experiment a feasibility study on the usefulness of a travelling comparison instrument (TCI) was conducted in order to evaluate continuous atmospheric CO2 and CH4 measurements at two European stations. The aim of the TCI is to independently measure ambient air in parallel to the standard station instrumentation, thus pr

Methane and carbon dioxide emissions from inland waters in India - implications for large scale greenhouse gas balances

Inland waters were recently recognized to be important sources of methane (CH4 ) and carbon dioxide (CO2 ) to the atmosphere, and including inland water emissions in large scale greenhouse gas (GHG) budgets may potentially offset the estimated carbon sink in many areas. However, the lack of GHG flux measurements and well-defined inland water areas for extrapolation, make the magnitude of the poten

Observing the continental-scale carbon balance: assessment of sampling complementarity and redundancy in a terrestrial assimilation system by means of quantitative network design

This paper investigates the relationship between the heterogeneity of the terrestrial carbon cycle and the optimal design of observing networks to constrain it. We combine the methods of quantitative network design and carbon-cycle data assimilation to a hierarchy of increasingly heterogeneous descriptions of the European terrestrial biosphere as indicated by increasing diversity of plant function

Response to letter to the editor 'Is red cell distribution width a biomarker in risk assessment of diabetes mellitus?

We thank Dr Kurt and colleagues for their comments and interest in our study. High red cell distribution width (RDW) is a new risk factor for cardiovascular disease (CVD), including heart failure, atrial fibrillation and cardiovascular mortality [2-4]. In a recent paper in the Journal of Internal Medicine we reported that low RDW is associated with increased incidence of diabetes [1]. This article

Numerical Predictions of Pressure Drop and Heat Transfer in a Blade Internal Cooling Passage with Continuous/Truncated Ribs

Ribs are often used in the mid-section of internal turbine blades to augment heat transfer from the blade wall to a coolant, but most research works are concerned only with continuous ribs attached to the side walls. In this paper, a turbulent flow and heat transfer of a rectangular passage with continuous and truncated ribs on opposite walls have been predicted numerically. Two types of ribs are

The Life History of 21 Breast Cancers

Cancer evolves dynamically as clonal expansions supersede one another driven by shifting selective pressures, mutational processes, and disrupted cancer genes. These processes mark the genome, such that a cancer's life history is encrypted in the somatic mutations present. We developed algorithms to decipher this narrative and applied them to 21 breast cancers. Mutational processes evolve across a

Measurements of the Total and Differential Higgs Boson Production Cross Sections Combining the H -> gamma gamma and H -> ZZ* -> 4l Decay Channels at root s=8 TeV with the ATLAS Detector

Measurements of the total and differential cross sections of Higgs boson production are performed using 20.3 fb(-1) of pp collisions produced by the Large Hadron Collider at a center-of-mass energy of root s = 8 TeV and recorded by the ATLAS detector. Cross sections are obtained from measured H -> gamma gamma and H -> ZZ*. 4l event yields, which are combined accounting for detector efficiencies, f

Helical differential X-ray phase-contrast computed tomography.

We report on the first experimental results of helical differential phase-contrast computed tomography (helical DPC-CT) with a laboratory X-ray tube source and a Talbot-Lau grating interferometer. The results experimentally verify the feasibility of helical data acquisition and reconstruction in phase-contrast imaging, in analogy to its use in clinical CT systems. This allows fast and continuous v

Plasticity of Cerebrovascular Smooth Muscle Cells After Subarachnoid Hemorrhage

Subarachnoid hemorrhage (SAH) is most often followed by a delayed phase of cerebral ischemia which is associated with high morbidity and mortality rates. The causes underlying this delayed phase are still unsettled, but are believed to include cerebral vasospasm, cortical spreading depression, inflammatory reactions, and microthrombosis. Additionally, a large body of evidence indicates that vascul

Advancing the Business and Human Rights Agenda: Dialogue, Empowerment, and Constructive Engagement

As corporations are going global, they are increasingly confronted with human rights challenges. As such, new ways to deal with human rights challenges in corporate operations must be developed as traditional governance mechanisms are not always able to tackle them. This article presents five different views on innovative solutions for the relationships between business and human rights that all b
