Plasma membrane expression of G protein-coupled estrogen receptor (GPER)/G protein-coupled receptor 30 (GPR30) is associated with worse outcome in metachronous contralateral breast cancer

Background G protein-coupled estrogen receptor (GPER), or G protein-coupled receptor 30 (GPR30), is reported to mediate non-genomic estrogen signaling. GPR30 associates with breast cancer (BC) outcome and may contribute to tamoxifen resistance. We investigated the expression and prognostic significance of GPR30 in metachronous contralateral breast cancer (CBC) as a model of tamoxifen resistance. M

Beyond genotype-phenotype maps : Toward a phenotype-centered perspective on evolution

Evolutionary biology is paying increasing attention to the mechanisms that enable phenotypic plasticity, evolvability, and extra-genetic inheritance. Yet, there is a concern that these phenomena remain insufficiently integrated within evolutionary theory. Understanding their evolutionary implications would require focusing on phenotypes and their variation, but this does not always fit well with t

Near-miss reporting among construction workers

In 2012, there were 11 000 accidents and near-miss reported of which most of it can be prevented. Though reporting and investigating injuries present a more detailed picture, this is still a lagging indicator — measuring after the event. Recording and investigating near misses, on the other hand, can be used as a positive indicator of performance tool to fix problems before injuries occur. Employe

EQ-5D utility, response and drug survival in rheumatoid arthritis patients on biologic monotherapy : A prospective observational study of patients registered in the south Swedish SSATG registry

Objectives Biologic agents have dramatically changed treatment of rheumatoid arthritis (RA). To date only scarce head-To-head data exist especially when the biological therapies are given as monotherapy without concomitant disease modifying drugs (DMARDs). Thus the objective of the current study is to evaluate treatment response of all available biological therapies with special focus on utility (

Local structural mechanism for enhanced energy storage properties in heterovalent doped NaNbO3 ceramics

In recent years, there is a growing interest for new lead-free oxides with reversible antiferroelectric (AFE)-ferroelectric (FE) phase transition for high-power energy-storage applications. NaNbO3-based ceramics are particularly attractive due to their easy synthesis and cost-effectiveness. In order to stabilize reversible AFE-FE phase transition, NaNbO3 is doped with a combination of heterovalent

Use of flutemetamol F18-labeled positron emission tomography and other biomarkers to assess risk of clinical progression in patients with amnestic mild cognitive impairment

Importance: Patients with amnestic mild cognitive impairment (aMCI) may progress to clinical Alzheimer disease (AD), remain stable, or revert to normal. Earlier progression to AD among patients who were β-amyloid positive vs those who were β-amyloid negative has been previously observed. Current research now accepts that a combination of biomarkers could provide greater refinement in the assessmen

Daylight Utilization with Light Pipe in Farm Animal Production: A Simulation Approach

Light pipes offer a passive way to bring daylight inside deep buildings, such as agricultural buildings. However, the lack of reliable performance predictability methods for light pipes represents a major obstacle preventing their widespread use. This paper evaluates a simulation approach for performance prediction and identifies key light pipe design parameters affecting their daylight transmissi

Highly range-resolved ammonia detection using near-field picosecond differential absorption lidar

Ammonia detection is highly relevant for combustion in boilers and furnaces since NH3 is able to suppress nitric oxide levels by catalytic as well as non-catalytic reduction. The mixing of ammonia with flue gases is an important parameter to obtain efficient non-catalytic reduction. In this paper picosecond DIAL was used for range-resolved, single ended, NH3 detection, utilizing a tunable picoseco

Interval Identification of FMR Parameters for Spin Reorientation Transition in (Ga,Mn)As

In this work we report results of ferromagnetic resonance studies of a 6% 15 nm (Ga,Mn)As layer, deposited on (001)-oriented GaAs. The measurements were performed with in-plane oriented magnetic field, in the temperature range between 5 K and 120 K. We observe a temperature induced reorientation of the effective in-plane easy axis from [(1) over bar 10] to [110] direction close to the Curie temper

Inflammation-sensitive plasma proteins are associated with future weight gain.

Cross-sectional studies have associated obesity and other components of the so-called metabolic syndrome with low-grade inflammation. The temporal and causal relations of this association have not been fully explored. This study explored whether elevated levels of inflammation-sensitive plasma proteins (ISPs) (fibrinogen, orosomucoid, {alpha}1-antitrypsin, haptoglobin, and ceruloplasmin) are assoc

Magnitude and time-course of arterio-venous differences in blood-alcohol concentration in healthy men

Background and objective: Human studies of arterio-venous (AV) differences in drug concentrations and the consequences for pharmacokinetic modelling and concentration-effect relationships are very limited. We therefore investigated the intravenous and intra-arterial concentrations of alcohol (ethanol) during the absorption, distribution and elimination stages of alcohol metabolism in healthy men.

Exploring the Possibilities of 14C Bomb-Pulse Dating of Human Tissue Samples

Popular Abstract in Swedish Levande organismer, inklusive människor, har en 14C/12C-kvot som återspeglar miljön. När materialet dör slutar kroppen att fylla på 14C och kroppens 14C börjar sönderfalla till 14N. Detta gav upphov till den klassiska 14C-dateringsmetoden, vilken utvecklades av professor W.F. Libby, 1949 och gav honom Nobelpriset i kemi 1960. 14C-datering används huvudsakligen inom arkeThe testing of nuclear weapons in the atmosphere, in the middle of the 20'h century, resulted in a bomb-pulse excess of atmospheric 14C. A bomb-pulse dating method was thus developed. The latter is a method to determine the time of formation of formerly living modern (i.e. living after 1955) material , based on the 14C/ 12C ratio in it. The objective of this work was to evaluate the factors that c

Industrial Robotics

Most robots today can trace their origin to early industrial robot designs. Much of the technology that makes robots more human-friendly and adaptable for different applications has emerged from manufacturers of industrial robots. Industrial robots are by far the largest commercial application of robotics technology today. All the important foundations for robot control were initially developed wi

Gene Therapy for Neurological Disorders

Popular Abstract in Danish Genterapi er en attraktiv terapiform mod neurologiske lidelser som Parkinsons sygdom og epilepsi af flere grunde. Gener med en terapeutisk effekt kan introduceres lokalt ved præcise injektioner i det syge væv, hvor genproduktet kan frigives fra nerveceller i respons til aktivitet i det omgivende væv. Ved genterapi omgås den forhindring som blod-hjernebarrieren udgør, ligGene therapy is an attractive strategy for neurological disorders, such as Parkinson’s disease and epilepsy, for several reasons. Introduction of genes with a therapeutic potential can be achieved locally, by accurate injections in the compromised tissue, and release of a transgene therapeutic substance can be regulated by the surrounding host neural circuitry. The gene therapy approach circumvent

Real-time observation of coherent acoustic phonons generated by an acoustically mismatched optoacoustic transducer using x-ray diffraction

The spectrum of laser-generated acoustic phonons in indium antimonide coated with a thin nickel film has been studied using time-resolved x-ray diffraction. Strain pulses that can be considered to be built up from coherent phonons were generated in the nickel film by absorption of short laser pulses. Acoustic reflections at the Ni-InSb interface leads to interference that strongly modifies the res

BACKGROUND. The aim of this study was to compare Perfadex with Euro-Collins solution regarding 24-hour preservation of endothelium-dependent relaxation and vascular smooth muscle function. METHODS. The infrarenal aorta of 72 isogenic rats was studied in organ baths as fresh controls, after 24 hours of cold (4 degrees C) storage, and after 24-hour storage followed by transplantation and examination

Finite volume for three-flavour Partially Quenched Chiral Perturbation Theory through NNLO in the meson sector

We present a calculation of the finite volume corrections to meson masses and decay constants in three flavour Partially Quenched Chiral Perturbation Theory ( PQChPT) through two-loop order in the chiral expansion for the flavour-charged ( or off-diagonal) pseudoscalar mesons. The analytical results are obtained for three sea quark flavours with one, two or three different masses. We reproduce the
