Prognostic Significance in Breast Cancer of a Gene Signature Capturing Stromal PDGF Signaling

In this study, we describe a novel gene expression signature of platelet-derived growth factor (PDGF) activated fibroblasts, which is able to identify breast cancers with a PDGF-stimulated fibroblast stroma and displays an independent and strong prognostic significance. Global gene expression was compared between PDGF-stimulated human fibroblasts and cultured resting fibroblasts. The most differen

EuraHS: the development of an international online platform for registration and outcome measurement of ventral abdominal wall hernia repair

Although the repair of ventral abdominal wall hernias is one of the most commonly performed operations, many aspects of their treatment are still under debate or poorly studied. In addition, there is a lack of good definitions and classifications that make the evaluation of studies and meta-analyses in this field of surgery difficult. Under the auspices of the board of the European Hernia Society

Vowel spaces in Swedish adolescents with cochlear implants

Abstract in UndeterminedThis paper examines vowel production in Swedish adolescents with cochlear implants. Twelve adolescents with cochlear implants and 11 adolescents with normal hearing participated. Measurements were made of the first and second formants in all the nine long Swedish vowels. The values in hertz were bark-transformed, and two measures of the size of the vowel space were obtained

Petrological discrimination among Precambrian dyke swarms: eastern Kaapvaal craton (South Africa)

Age-determinations on a complex array of mafic dykes across the eastern Kaapvaal craton (Olsson et al.. 2010) are complemented herein by field evidence, dyke trend analysis, and petrological characterization of 58 dyke samples. similar to 2.95 Ga SE-trending, a similar to 2.65 Ga E- to SE-radiating, and similar to 1.90 Ga NE-trending swarms can be distinguished. Prominent Archean (similar to 2.95

The nasal mucosa contains a large diversity of human papillomavirus from the Beta- and Gammapapillomavirus genera.

Background. Human papillomavirus (HPV) types from the Beta- and Gammapapillomavirus genera are common at cutaneous sites. The aim of this study was to analyze the prevalence of these HPV types in oral and nasal samples.Methods. Nasal and oral samples were taken from 312 volunteers of Danish health-care staff (240 women and 72 males, with mean age of 42 years). Of these 311 oral and 304 nasal sampl

Prevention of acute knee injuries in adolescent female football players: cluster randomised controlled trial

Objective To evaluate the effectiveness of neuromuscular training in reducing the rate of acute knee injury in adolescent female football players. Design Stratified cluster randomised controlled trial with clubs as the unit of randomisation. Setting 230 Swedish football clubs (121 in the intervention group, 109 in the control group) were followed for one season (2009, seven months). Participants 4

Equivocation for the Objective Bayesian

According to Williamson (In defense of objective Bayesianism, Oxford University Press, Oxford, 2010), the difference between empirical subjective Bayesians and objective Bayesians is that, while both hold reasonable credence to be calibrated to evidence, the objectivist also takes such credence to be as equivocal as such calibration allows. However, Williamson's prescription for equivocation gener

The Conditional Effects of Market Power on Bank Risk--Cross-Country Evidence

We investigate the relationship between market power and risk for a large panel of banks worldwide. Loan and deposit market power are measured separately at bank-year level, and the risk effect of market power is conditioned on several factors predicted by theory. Both loan and deposit market power have a stable, monotonically negative effect on risk, irrespective of risk measure. The effect is la

Quantitative reconstructions of changes in regional openness in north-central Europe reveal new insights into old questions

By applying the recently developed model REVEALS (Regional Estimates of VEgetation Abundance from Large Sites) (Sugita, 2007) to pollen data from a large number of sites across Northern Germany and Denmark, we construct maps of regional patterns in landscape openness and in cover abundance of key plant taxa in the cultural landscape of north-central Europe for selected time slices in the Holocene.

Determination of diffusion lengths in nanowires using cathodoluminescence

We used cathodoluminescence imaging to determine diffusion lengths in III-V semiconductor nanowires, grown by metal-organic chemical vapor deposition seeded by gold nanoparticles. Intensity profiles were recorded either from the interface between the substrate and homogeneous nanowires, or from segments in nanowires containing axial heterostructures to determine the diffusion length. We determined

Minimum viewing angle for visually guided ground speed control in bumblebees.

To control flight, flying insects extract information from the pattern of visual motion generated during flight, known as optic flow. To regulate their ground speed, insects such as honeybees and Drosophila hold the rate of optic flow in the axial direction (front-to-back) constant. A consequence of this strategy is that its performance varies with the minimum viewing angle (the deviation from the

Suspended InAsnanowire gate-all-around field-effect transistors

Gate-all-around field-effect transistors are realized with thin, single-crystalline, pure-phase InAs nanowires grown by molecular beam epitaxy. At room temperature, the transistors show a desired high on-state current I-on of similar to 10 mu A arid an on-off current ratio I-on/I-off of as high as 10(6) at sourcedrain bias voltage of 50 mV and gate length of 1 mu m with a gate underlap spacing of

Centrality dependence of high-p(T) D meson suppression in Pb-Pb collisions at root s(NN)=2.76 TeV

The nuclear modification factor, R-AA, of the prompt charmed mesons D-0, D+ and D*+, and their antiparticles, was measured with the ALICE detector in Pb-Pb collisions at a centre-of-mass energy root s(NN) = 2 : 76 TeV in two transverse momentum intervals, 5 < p(T) < 8 GeV/c and 8 < p(T) < 16 GeV/c, and in six collision centrality classes. The R-AA shows a maximum suppression of a factor of 5{6 in

Polymorphic male color morphs visualized with steroids in monomorphic females: a tool for designing analysis of sex-limited trait inheritance

In diploid animals, males and females share most of the genome (except sex-specific elements, such as sex chromosome genes), yet despite sharing the underlying genes that hard-wire traits, males and females may differ in their phenotypes when traits are controlled by proximate mechanisms, such as hormones. In color polymorphic species where coloration is only expressed in one sex, the design of st

Suppression of high transverse momentum D mesons in central Pb-Pb collisions at root s(NN)=2.76 TeV

The production of the prompt charm mesons D-0, D+, D*(+), and their antiparticles, was measured with the ALICE detector in Pb-Pb collisions at the LHC, at a centre-of-mass energy root s(NN) = 2.76 TeV per nucleon-nucleon collision. The p(t)-differential production yields in the range 2 < p(t) < 16 GeV/c at central rapidity, vertical bar y vertical bar < 0.5, were used to calculate the nuclear modi

Personalizing pancreatic cancer medicine: what are the challenges?

The P4 paradigm for future medicine promises changes in cancer management with improved Prediction of treatment response, Prevention of disease, Personalization of therapy, and Participation by patients. Significant challenges remain for the implementation of the P4 principles for pancreatic cancer, but many strides have been made in the past several years that should facilitate a future in which

Cardiovascular function in children born very preterm after intrauterine growth restriction with severely abnormal umbilical artery blood flow.

AIMS: Low birthweight has been linked to increased cardiovascular risk in adulthood. We evaluated the effect on cardiovascular outcome of intrauterine growth restriction (IUGR) with abnormal fetal blood flow in children born very preterm. METHODS: Blood pressure, cardiac function and size, diameters, distensibility, and stiffness of the abdominal aorta, carotid, and popliteal arteries, and endothe

Structural Anisotropy in Polar Fluids Subjected to Periodic Boundary Conditions

Abstract in UndeterminedA heuristic model based on dielectric continuum theory for the long-range solvation free energy of a dipolar system possessing periodic boundary conditions (PBCs) is presented. The predictions of the model are compared to simulation results for Stockmayer fluids simulated using three different cell geometries. The boundary effects induced by the PBCs are shown to lead to an
