Is one month treatment with dabigatran before cardioversion of atrial fibrillation sufficient to prevent thromboembolism?

The use of direct oral anticoagulants (DOACs) in patients undergoing elective direct current (DC) cardioversion of non-acute atrial fibrillation (AF) can potentially shorten the time from initiation of anticoagulation treatment to cardioversion, compared with warfarin. The safety of this strategy needs to be investigated. Data from subgroup analysis from clinical trials with DOAC do not clarify wh

Minute-sized crystals pf HFSE minerals in evolved, fluorite-bering granite : an example from the Sörvik granite, central Sweden

SEM-EDS techniques are used to study minute-sized crystals of HFSE minerals in an evolved batch of fluorine-rich granite. The batch separated due to buoyancy from the bulk magma before fluid separation was reached. Fluorine acted as the main complexing agent in the magma, facilitating the transport of many elements. Enhanced concentrations of elements like Nb, Y, REE, Th and possibly Be gave the g

Agglomeration Economies in Classical Music

This study investigates agglomeration effects for classical music production in a wide range of cities for a global sample of composers born between 1750 and 1899. Theory suggests a trade-off between agglomeration economies (peer effects) and diseconomies (peer crowding). I test this hypothesis using historical data on composers and employ a unique instrumental variable - a measure of birth centra

Insulin-like growth factor I and risk of epithelial invasive ovarian cancer by tumour characteristics: results from the EPIC cohort

Background: Prospective studies on insulin-like growth factor I (IGF-I) and epithelial ovarian cancer (EOC) risk are inconclusive. Data suggest risk associations vary by tumour characteristics. Methods: We conducted a nested case-control study in the European Prospective Investigation into Cancer and Nutrition (EPIC) to evaluate IGF-I concentrations and EOC risk by tumour characteristics (n = 565

CYLD regulates HGF expression in hepatic stellate cells via interaction with HDAC7.

Hepatic fibrosis is considered as a physiological wound-healing response to liver injury. The process involves several factors, such as the hepatocyte growth factor (HGF), which restrain hepatic injury and facilitate the reversibility of the fibrotic reaction in response to an acute insult. Chronic liver injury and sustained inflammation cause progressive fibrosis and, ultimately, organ dysfunctio

Infection intensity and infectivity of the tick-borne pathogen Borrelia afzelii.

The 'trade-off' hypothesis for virulence evolution assumes that between-host transmission rate is a positive and saturating function of pathogen exploitation and virulence, but there are as yet few tests of this assumption, in particular for vector-borne pathogens. Here, I show that the infectivity (probability of transmission) of the tick-borne bacterium Borrelia afzelii from two of its natural r

High prevalence of pituitary dysfunction after aneurysmal subarachnoid hemorrhage: a long-term prospective study using dynamic endocrine testing.

Impaired systemic hormonal activity caused by hypothalamic and pituitary injury may contribute to neuropsychological disturbances and poor quality of life following aneurysmal subarachnoid hemorrhage (SAH). This prospective study was designed to longitudinally evaluate long-term clinical outcome and pituitary function after SAH, using dynamic tests for adrencorticotropic and somatotropic secretory

Process-based models not always better than empirical models for predicting budburst of Norway spruce and birch in Europe.

Budburst models have mainly been developed to capture the processes of individual trees, and vary in their complexity and plant physiological realism. We evaluated how well eleven models capture the variation in budburst of birch and Norway spruce in Germany, Austria, the United Kingdom and Finland. The comparison was based on the models performance in relation to their underlying physiological as

Multi-professional and multi-dimensional group education - a key to action in elderly persons

Purpose: This study was intended to evaluate a multi-professional health-promoting and disease-preventive intervention organized as multi-professional senior group meetings, which addressed home-dwelling, independently living, cognitively intact elderly persons (80 +/-), by exploring the participants' experiences of the intervention. Method: The focus group methodology was used to interview a tota

Social Network Characteristics and Daily Smoking among Young Adults in Sweden

A large number of studies have shown that friends’ smoking behavior is strongly associated with an individual’s own risk for smoking. However, few studies have examined whether other features of social networks, independently or conjointly with friends’ smoking behavior, may influence the risk for smoking. Because it is characterized by the growing importance of friendship networks, the transition

A search for t(t)over-bar resonances in lepton plus jets events with highly boosted top quarks collected in pp collisions at root s=7 TeV with the ATLAS detector

A search for resonant production of high-mass top-quark pairs is performed on 2.05 fb(-1) of proton-proton collisions at root s = 7 TeV collected in 2011 with the ATLAS experiment at the Large Hadron Collider. This analysis of the lepton+jets final state is specifically designed for the particular topology that arises from the decay of highly boosted top quarks. The observed t (t) over bar invaria

Re-Os and U-Pb constraints on gold mineralisation events in the Meso- to Neoarchaean Storo greenstone belt, Storo, southern West Greenland

The Storo greenstone belt in Godthabsfjord, southern West Greenland consists of juxtaposed rock units of different age and origin, and hosts gold mineralisation that is associated with arsenopyrite along a contact between lithological units and along the axial plane of a large fold core. The age and origin of the gold is debatable, but in this paper, we present new arsenopyrite Re-Os and zircon U-

Molecular Dynamics Simulations of Intrinsically Disordered Proteins: Force Field Evaluation and Comparison with Experiment

An increasing number of studies using molecular dynamics (MD) simulations of unfolded and intrinsically disordered proteins (IDPs) suggest that current force fields sample conformations that are overly collapsed. Here, we study the applicability of several state-of-the-art MD force fields, of the AMBER and GROMOS variety, for the simulation of Histatin 5, a short (24 residues) cationic salivary ID

Efficient broadcasting in radio networks with long-range interference

We study broadcasting, also known as one-to-all communication, in synchronous radio networks with known topology modeled by undirected (symmetric) graphs, where the interference range of a node is likely exceeding its transmission range. In this model, if two nodes are connected by a transmission edge they can communicate directly. On the other hand, if two nodes are connected by an interference e

Environmental clustering of drug abuse in households and communities: multi-level modeling of a national Swedish sample

Both epidemiological and genetically informative studies indicate that shared environmental influences contribute to resemblance in siblings for drug abuse (DA). To what degree do these influences arise from living in the same household versus residing in the same community? We performed a cross-classified multi-level logistic regression on all individuals born in Sweden 1975-1990 (N = 1558,654).

Economic considerations related to choice of intraocular lens (IOL) and posterior capsule opacification frequency - a comparison of three different IOLs.

Purpose: To evaluate the posterior capsule opacification (PCO) rates in three different modern standard intraocular lenses (IOL) and analyse the related cost. Methods: Retrospective study of medical records from 1527 patients who underwent uneventful cataract surgery by phacoemulsification with posterior chamber implantation of either AcrySof SN60 (n = 375), Akreos Adapt (n = 350) or Tecnis Acryl
