Nonpharmacologic Interventions Need Outcomes for Evaluating Complex Interventions in Rheumatic Diseases

Introduction. Nonpharmacologic interventions are themselves complex and are often combined with drugs and other interventions in the treatment of rheumatic diseases. Therefore, overall strategies for treatment are complex interventions. These should be evaluated regarding their processes and outcomes. Methods. The CARE network, an international organization of health professionals (physicians and

Modern treatment of acute mesenteric ischaemia.

Diagnosis of acute mesenteric ischaemia in the early stages is now possible with modern computed tomography (CT), using intravenous contrast enhancement and imaging in the arterial and/or portal venous phase. The availability of CT around the clock means that more patients with acute mesenteric ischaemia may be treated with urgent intestinal revascularization.

Stability Analysis of Transportation Networks with Multiscale Driver Decisions

Stability of Wardrop equilibria is analyzed for dynamical transportation networks in which the drivers' route choices are influenced by information at multiple temporal and spatial scales. The considered model involves a continuum of nonatomic indistinguishable drivers commuting between a common origin-destination pair in an acyclic transportation network. The drivers' route choices are affected b

Ectoine-mediated protection of enzyme from the effect of pH and temperature stress: a study using Bacillus halodurans xylanase as a model.

Compatible solutes are small, soluble organic compounds that have the ability to stabilise proteins against various stress conditions. In this study, the protective effect of ectoines against pH stress is examined using a recombinant xylanase from Bacillus halodurans as a model. Ectoines improved the enzyme stability at low (4.5 and 5.0) and high pH (11 and 12); stabilisation effect of hydroxyecto

Fifty thousand years of arctic vegetation change and megafauna diet

Although it is generally agreed that the Arctic flora is among the youngest and least diverse on Earth, the processes that shaped it are poorly understood. Here we present 50 thousand years (kyr) of Arctic vegetation history, derived from the first large-scale ancient DNA metabarcoding study of circumpolar plant diversity. For this interval we also explore nematode diversity as a proxy for modelli

Organoclay polypropylene nanocomposites under different electric field strengths

Functionalities of clay-polymer nanocomposites (CPN) are related to the degree of clay particle exfoliation and orientation within the polymer matrix. Exploration of new physical methods for such CPN processing is currently an active field of research. In the present work, organoclay polypropylene nanocomposites were prepared by melt intercalation and subsequently exposed to an electric field (E)

The risk of pneumococcal infections after immunization with pneumococcal conjugate vaccine compared to non-vaccinated inflammatory arthritis patients.

Objectives: To examine the risk of putative pneumococcal infections in adult arthritis patients on different anti-rheumatic drugs immunized with heptavalent pneumococcal conjugate vaccine (Prevenar 7; PCV7) and non-vaccinated individually matched arthritis patients. Method: All individuals in a cohort of 505 patients with rheumatoid arthritis (RA) or spondylarthropathy (SpA) receiving different an

LTX-109 is a Novel Agent for Nasal Decolonisation of Methicillin Resistant and Sensitive Staphylococcus aureus.

Nasal decolonisation has a proven effect on the prevention of severe Staphylococcus aureus infections and in the control of methicillin resistant S. aureus (MRSA). However, rising rates of resistance to antibiotics highlights the need for new substances for nasal decolonisation. LTX-109 is a broad spectrum, fast-acting bactericidal antimicrobial drug for topical treatment, which causes membrane di

A late Archaean radiating dyke swarm as possible clue to the origin of the Bushveld Complex

The Bushveld Complex in South Africa represents the world's largest intrusion of magnesium-and iron-rich magmas. The Bushveld magmas were emplaced beneath the Transvaal basin(1) similar to 2.06 billion years ago(2,3), but their origin remains elusive. The magmas may have formed in response to an upwelling mantle plume(4), ancient subduction5 or melting triggered by a meteorite impact(6). Here we u

Photoluminescence study of as-grown vertically standing wurtzite InP nanowire ensembles.

We demonstrate a method that enables the study of photoluminescence of as-grown nanowires on a native substrate by non-destructively suppressing the contribution of substrate photoluminescence. This is achieved by using polarized photo-excitation and photoluminescence and by making an appropriate choice of incident angle of both excitation beam and photoluminescence collection direction. Using T-p

Random mutagenesis of amelogenin for engineering protein nanoparticles.

Nanoparticles made from recombinant proteins offer excellent potential for several nanotechnological applications. However, only a very limited number of proteins are currently being used for such purposes due to limited availability and stability. Therefore, we have investigated the enamel matrix protein amelogenin as a new alternative protein for use as recombinant nanoparticles. Amelogenin is a

Polymorphisms in Genes Encoding Potential Mercury Transporters and Urine Mercury Concentrations in Populations Exposed to Mercury Vapor from Gold Mining.

Background: Elemental mercury (Hg0) is widely used in small-scale gold mining. Individuals working or living in mining areas have high urinary concentrations of Hg (U-Hg). Differences in genes encoding potential Hg-transporters may affect uptake and elimination of Hg. Objective: To identify single nucleotide polymorphisms (SNPs) in Hg-transporter genes that modify U-Hg. Methods: 1,017 men and wome

Computational De Novo Design of a Self-Assembling Peptide with Predefined Structure.

Protein and peptide self-assembly is a powerful design principle for engineering of new biomolecules. More sophisticated biomaterials could be built if both the structure of the overall assembly and that of the self-assembling building block could be controlled. To approach this problem, we developed a computational design protocol to enable de novo design of self-assembling peptides with predefin

Motor skills and school performance in children with daily physical education in school - a 9-year intervention study.

The aim was to study long-term effects on motor skills and school performance of increased physical education (PE). All pupils born 1990-1992 from one school were included in a longitudinal study over nine years. An intervention group (n = 129) achieved daily PE (5 × 45 min/week) and if needed one extra lesson of adapted motor training. The control group (n = 91) had PE two lessons/week. Motor ski

Which are the most important parameters for modelling carbon assimilation in boreal Norway spruce under elevated [CO2] and temperature conditions?

Photosynthesis is highly responsive to environmental and physiological variables, including phenology, foliage nitrogen (N) content, atmospheric CO2 concentration ([CO2]), irradiation (Q), air temperature (T) and vapour pressure deficit (D). Each of these responses is likely to be modified by long-term changes in climatic conditions such as rising air temperature and [CO2]. When modelling photosyn

III-V Nanowire MOSFETs in RF-Applications

InAs nanowires have been used to fabricate high-performance MOSFETs that have been integrated into small-scale RF-circuits. We describe the strategy for the design of the transistor architecture and present data for the DC and high-frequency performance. Studies of the 1/f-noise show competitive normalized noise spectral density although it suggests the presence of defects within the high-k film t
