In late 2011 The Swedish Society of Radiation Physics formed a working group to concentrate on the Quality Assurance of modern radiation therapy techniques. The given task was to identify and summarise the different QA strategies in Sweden and also the international recommendations. This was used to formulate recommendations for practical guidelines within Sweden. In this paper a brief summery of

Recent epidemiological investigations have reported on the association between telomere length (TL) and a number of malignancies, including B-cell lymphoma (BCL). The reported results for BCLs are however inconsistent. We carried out a nested case-control study to determine whether TL is associated with future risk of BCL. Using quantitative polymerase chain reaction, the relative TL (i.e. the rat

One challenging task in building (bio)chemical sensors is the efficient and stable immobilization of receptor on a suitable transducer. Herein, we report a method for covalent immobilization of molecularly imprinted core-shell nanoparticles for construction of robust chemical sensors. The imprinted nanoparticles with a core-shell structure have selective molecular binding sites in the core and mul

We present a new method for preparation of protein-specific polymer beads based on surface molecular imprinting in Pickering emulsion. In the first step, adult human hemoglobin (Hb) was adsorbed on silica nanoparticles. The protein-coated silica particles were then used to stabilize an oil-in-water emulsion (Pickering emulsion) composed of cross-linking monomer in the oil phase. After free radical

Glycosaminoglycans (GAGs) are negatively charged polysaccharides present, e.g., on the luminal face of the blood vessels as heparan sulphate (HS) and hyaluronic acid (HA), in the interstitium as HA, and in neutrofils and plasma as chondroitin sulphate (CS) and HA. Total plasma levels of GAG are increased in human septic shock, but the origin and pathophysiological implications are unclear. In orde

Spx is a global regulator that is widespread among the low G+C Gram-positive bacteria. Spx has been extensively studied in Bacillus subtilis, where it acts as an activator and a repressor of transcription in response to disulfide stress. Under non-stress conditions, Spx is rapidly degraded by the ClpXP protease. This degradation is enhanced by the YjbH adaptor protein. Upon disulfide stress, the a

Dijet events produced in LHC proton-proton collisions at a center-of-mass energy root s = 8 TeV are studied with the ATLAS detector using the full 2012 data set, with an integrated luminosity of 20.3 fb(-1). Dijet masses up to about 4.5 TeV are probed. No resonancelike features are observed in the dijet mass spectrum. Limits on the cross section times acceptance are set at the 95% credibility leve

Methacrylic acid was produced in high yield by an integrated process involving bioconversion of 2-methyl-1,3-propanediol (2M1,3PD) to 3-hydroxy-2-methylpropionic acid (3H2MPA) via 3-hydroxy-2-methylpropanal (3H2MPAL), and catalytic dehydration of the resulting acid. Whole cells of Gluconobacter oxydans grown on glycerol-based culture medium were used as the catalyst for oxidative biotransformation

The 1960s marked the beginning of a new era of family and gender relations in Sweden. It was a time when traditional values and ideas concerning the family were questioned and redefined in policymaking. The Women's movement and political radicalization underpinned the emergence of gender equality policy ambitions, culminating in several gender neutral reforms in the 1970s. These policy ambitions c

Retrospective studies have suggested a beneficial effect of lipid-lowering treatment on the progression of aortic stenosis (AS) in milder stages of the disease. In the randomized, placebo-controlled Simvastatin and Ezetimibe in Aortic Stenosis (SEAS) study, 4.3 years of combined treatment with simvastatin 40 mg and ezetimibe 10 mg did not reduce aortic valve events (AVEs), while ischemic cardiovas

Resolving the genetic basis of complex diseases like rheumatoid arthritis will require knowledge of the corresponding diseases in experimental animals to enable translational functional studies. Mapping of quantitative trait loci in mouse models of arthritis, such as collagen-induced arthritis (CIA), using F-2 crosses has been successful, but can resolve loci only to large chromosomal regions. Usi

Hearing screening has been proposed to promote help-seeking and rehabilitation in adults with hearing impairment. However, some longitudinal studies point to low help-seeking and subsequent rehabilitation after a failed hearing screening (positive screening result). Some barriers to help-seeking and rehabilitation could be intrinsic to the profiles and needs of people who have failed a hearing scr

To review and update the evidence on predictors of poor outcome (death, persistent vegetative state or severe neurological disability) in adult comatose survivors of cardiac arrest, either treated or not treated with controlled temperature, to identify knowledge gaps and to suggest a reliable prognostication strategy.

Activation of the complement system by tumor cells was long believed to only benefit the host. Overexpression of complement inhibitors by many tumor cell types and results obtained in several experimental animal models were all in agreement with this hypothesis. However, recent reports imply that the situation is more complex than initially believed and that under certain circumstances tumor cells

How do females decide which males to accept or reject as potential mates when the individuals encountered are unfamiliar and may be either heterospecifics or conspecifics? Learning often influences the development of mate preferences. Experience with particular phenotypes often positively biases preference for that phenotype. However, experience can also induce aversion. We studied the effect of s

A search for the neutral Higgs bosons predicted by the Minimal Supersymmetric Standard Model (MSSM) is reported. The analysis is performed on data from proton-proton collisions at a centre-of-mass energy of 8 TeV collected with the ATLAS detector at the Large Hadron Collider. The samples used for this search were collected in 2012 and correspond to integrated luminosities in the range 19.5-20.3 fb

Purpose of review: We review recent evidence regarding risk factors for childhood posttraumatic stress disorder (PTSD) and treatment outcome studies from 2010 to 2012 including dissemination studies, early intervention studies and studies involving preschool children.Recent findings: Recent large-scale epidemiological surveys confirm that PTSD occurs in a minority of children and young people expo
