A search for pair-produced third generation scalar leptoquarks is presented, using proton-proton collisions at root s = 7 TeV at the LHC. The data were recorded with the ATLAS detector and correspond to an integrated luminosity of 4.7 fb(-1). Each leptoquark is assumed to decay to a tau lepton and a b-quark with a branching fraction equal to 100%. No statistically significant excess above the Stan

High achievement in school has been associated with increased risk of eating disorders, including anorexia nervosa (AN) and bulimia nervosa (BN), but causality of these relationships is unclear. We sought to examine the association between school achievement and AN or BN in a national cohort and to determine the possible contribution of familial confounding using a co-relative design.

We investigate the dependence of resonance energy transfer from Wannier-Mott excitons to an organic overlayer on exciton dimensionality. We exploit the excitonic potential disorder in a single quantum well to tune the balance between localized and free excitons by scaling the Boltzmann distribution of excitons through temperature. Theoretical calculations predict the experimentally observed temper

Background: The CC-chemokine receptor-3 (CCR3) has emerged as a target molecule for pharmacological intervention in allergic inflammation. Objective: To examine whether a dual CCR3 and H-1-receptor antagonist (AZD3778) affects allergic inflammation and symptoms in allergic rhinitis. Methods: Patients with seasonal allergic rhinitis were subjected to three seven days' allergen challenge series. Tre

BACKGROUND: Concern regarding recurrence of pre-transplant (Tx) malignancy has disqualified patients from Tx. Because this has been poorly studied in lung and heart Tx recipients our aim was to investigate the influence of pre-Tx malignancy on post-Tx recurrence and long-term survival, focusing on pre-operative cancer-free intervals. METHODS: From our lung and heart Tx programs (1983 to 2011) we r

In the current paper, we derive a rigorous convergence analysis for a broad range of splitting schemes applied to abstract nonlinear evolution equations, including the Lie and Peaceman-Rachford splittings. The analysis is in particular applicable to (possibly degenerate) quasilinear parabolic problems and their dimension splittings. The abstract framework is based on the theory of maximal dissipat

Hemoglobin (Hb) is one of the most studied proteins. However, oxidative toxicity associated with free Hb in circulation and its contribution to inflammation and complications of transfusion have only recently become active areas of research. New insights into the protective mechanisms of haptoglobin (Hp), a plasma protein, and a timely resolution of the crystal structure of the Hb-Hp complex made

The scientific objectives of the Cain mission cover areas of galactic structure and evolution, stellar astrophysics, exoplanets, solar system physics, and fundamental physics. Astrometrically, its main contribution will be the determination of millions of absolute stellar parallaxes and the establishment of a very accurate, dense and faint non-rotating optical reference frame. With a planned launc

Biomass will make a vital contribution to the EU renewable energy targets, however large amounts need to be mobilised to achieve policy goals. To promote action, the European Commission sent a firm call to member states for coordinated biomass strategies and plans, and engagement of sub-national actors. This paper examines how regional level biomass planning can benefit national planning and EU ta

In a number of autoimmune diseases, for example, rheumatoid arthritis and systemic lupus erythematosus, it is known that autoantibodies are present before the clinical onset. Recently we have shown that autoantibodies can be found many years before symptom onset in primary Sjögren's syndrome. This implies that screening for autoantibodies may be used to identify individuals at risk of developing s

Subendothelial LDL-adhesion and its subsequent oxidation are considered as key events in the development of atherosclerotic lesions. During oxidation of LDL, reactive aldehydes such as malondialdehyde (MDA) are formed, which modify apolipoprotein B100. However, the possibility that these reactive aldehydes could leak out of the LDL-particle and modify surrounding extracellular matrix proteins has

Protein affinity reagents (PARs), most commonly antibodies, are essential reagents for protein characterization in basic research, biotechnology, and diagnostics as well as the fastest growing class of therapeutics. Large numbers of PARs are available commercially; however, their quality is often uncertain. In addition, currently available PARs cover only a fraction of the human proteome, and thei

P>1. Avian embryos depend on the incubating parent to provide a thermal environment suitable for embryogenesis, but as the maintenance of optimal incubation temperatures is energetically costly, an incubating bird often must trade off embryonic investment against self-maintenance. 2. We manipulated the energetic cost of incubation in female zebra finches (Taeniopygia guttata Vieillot) by varying a

Introduction: Induced hypothermia has been shown to improve outcome after cardiac arrest, but early prognostication is hampered by the need for sedation. Here we tested whether a biomarker for neurodegeneration, the neurofilament heavy chain (NfH), may improve diagnostic accuracy in the first days after cardiac arrest. Methods: This prospective study included 90 consecutive patients treated with h

Purpose: Lung cancer is the worldwide leading cause of death from cancer. DNA methylation in gene promoter regions is a major mechanism of gene expression regulation that may promote tumorigenesis. However, whether clinically relevant subgroups based on DNA methylation patterns exist in lung cancer remains unclear. Experimental Design: Whole-genome DNA methylation analysis using 450K Illumina Bead

The adsorption of ammonia on Au(111)-supported monolayers of iron phthalocyanine has been investigated by x-ray photoelectron spectroscopy, x-ray absorption spectroscopy, and density functional theory calculations. The ammonia-induced changes of the x-ray photoemission lines show that a dative bond is formed between ammonia and the iron center of the phthalocyanine molecules, and that the local sp

In 1961, Ernst Mayr published a highly influential article on the nature of causation in biology, in which he distinguished between proximate and ultimate causes. Mayr argued that proximate causes (e.g. physiological factors) and ultimate causes (e.g. natural selection) addressed distinct 'how' and 'why' questions and were not competing alternatives. That distinction retains explanatory value toda
