Socioeconomic factors and mortality in patients with atrial fibrillation-a cohort study in Swedish primary care

Background: Preventing ischaemic stroke attracts significant focus in atrial fibrillation (AF) cases. Less is known on the association between socioeconomic factors and mortality and cardiovascular outcomes in patients with AF. Methods: Our study population included adults (n=12 283) ≥45 years diagnosed with AF at 75 primary care centres in Sweden 2001-07. Cox regression was used to calculate haza

Defect-free SnTe topological crystalline insulator nanowires grown by molecular beam epitaxy on graphene

SnTe topological crystalline insulator nanowires have been grown by molecular beam epitaxy on graphene/SiC substrates. The nanowires have a cubic rock-salt structure, they grow along the [001] crystallographic direction and have four sidewalls consisting of {100} crystal planes known to host metallic surface states with a Dirac dispersion. Thorough high resolution transmission electron microscopy

A comprehensive evaluation of the genetic architecture of sudden cardiac arrest

Aims: Sudden cardiac arrest (SCA) accounts for 10% of adult mortality in Western populations. We aim to identify potential loci associated with SCA and to identify risk factors causally associated with SCA. Methods and results: We carried out a large genome-wide association study (GWAS) for SCA (n = 3939 cases, 25 989 non-cases) to examine common variation genome-wide and in candidate arrhythmia g

DNA Methylation of LRRC3B : A Biomarker for Survival of Early-Stage Non-Small Cell Lung Cancer Patients

Background: Previous studies support a tumor-suppressor role for LRRC3B across various types of cancers. We aimed to investigate the association between DNA methylation of LRRC3B and overall survival (OS) for patients with early-stage non-small cell lung cancer (NSCLC).Methods: This study included 1,230 patients with early-stage NSCLC. DNA was extracted from lung tumor tissues and DNA methylation

Abdominell rektusdiastas kan ge funktionella besvär - Indikation för behandling måste förtydligas

En kvarstående abdominell rektusmuskeldiastas hos kvinnor efter förlossning är vanlig och kan medföra försämrad bålmuskelfunktion och hos en del patienter avsevärt nedsatt livskvalitet.Den vetenskapliga evidensen för val av behandling av abdominell rektusmuskeldiastas är svag. Fysioterapi med bålstabiliserande träning bör vara förstahandsval.Hos en liten grupp med mer uttalade besvär där fysiotera

Ex vivo recordings reveal desert locust forelimb control is asymmetric

Lateralized behaviours are widespread among the animals, including insects with their miniature brains, perhaps being a way of maximising neural capacity (reviewed in [1,2]). However, evidence for functional asymmetries in the neural circuitry itself is scarce. Here, using bilateral simultaneous recordings from the ex vivo nervous system of desert locusts, we show that the neural control of their

Wind Turbine Noise and Sleep : Pilot Studies on the Influence of Noise Characteristics

The number of onshore wind turbines in Europe has greatly increased over recent years, a trend which can be expected to continue. However, the effects of wind turbine noise on long-term health outcomes for residents living near wind farms is largely unknown, although sleep disturbance may be a cause for particular concern. Presented here are two pilot studies with the aim of examining the acoustic

Thermoelectric Characterization of the Kondo Resonance in Nanowire Quantum Dots

We experimentally verify hitherto untested theoretical predictions about the thermoelectric properties of Kondo correlated quantum dots (QDs). The specific conditions required for this study are obtained by using QDs epitaxially grown in nanowires, combined with a recently developed method for controlling and measuring temperature differences at the nanoscale. This makes it possible to obtain data

Inverse modelling and combined state-source estimation for chemical weather

Air quality data assimilation aims to find a best estimate of the control parameters (see theory chapter) for those processes of the atmosphere which govern the chemical evolution of biologically relevant height levels, typically located in the the lowermost atmosphere. As in data assimilation (see theory chapters), we have to resort to numerical models to complement usually sparse observation net

Four-dimensional variational assimilation of atmospheric chemical data - Application to regional modelling of air quality

The chemistry transport model system EURAD-IM and its variational data assimilation implementation are applied to air quality assessment problems. The facility of joint initial value and emission rate optimisation together with a nested 4d-var module is employed to the measurement campaign BERLIOZ. To emphasise the benefits of computationally efficient data assimilation for monitoring and simulati

Small-molecule inhibitor of OGG1 suppresses proinflammatory gene expression and inflammation

The onset of inflammation is associated with reactive oxygen species and oxidative damage to macromolecules like 7,8-dihydro-8-oxoguanine (8-oxoG) in DNA. Because 8-oxoguanine DNA glycosylase 1 (OGG1) binds 8-oxoG and because Ogg1-deficient mice are resistant to acute and systemic inflammation, we hypothesized that OGG1 inhibition may represent a strategy for the prevention and treatment of inflam

Serotypes with low invasive potential are associated with an impaired antibody response in invasive pneumococcal disease

Pneumococcal polysaccharide vaccines may elicit a hyporesponse under certain conditions. There is limited knowledge, however, on the type of specific antibody response in individuals with invasive pneumococcal disease (IPD). The aim of this study was to investigate the functional antibody response in patients with IPD caused by different serotypes. Pre-immune and convalescent sera from 40 patients

German winegrowers' motives and barriers to convert to organic farming

Agriculture plays a crucial role in meeting the Sustainable Development Goals, with organic farming being one important potential contributor to environmental, economic, and social sustainability. Despite a national goal of 20% organic agriculture, currently only 6.2% of Germany's farmland is organic, and conversion rates are slowing down. However, one bright spot is organic viticulture in Germany

Self-recordings of upper arm elevation during cleaning - Comparison between analyses using a simplified reference posture and a standard reference posture

Background: To reduce ergonomic risk factors in terms of awkward and constrained postures and high velocities, it is important to perform adequate risk assessments. Technical methods provide objective measures of physical workload. These methods have so far mainly been used by researchers. However, if written instructions how to apply the sensors and how to adopt the reference posture are provided
