Background: The Swedish National Register for Oesophageal and Gastric Cancer (NREV) was launched in 2006. Data are reported at diagnosis (diagnostic survey), at the time of surgery (surgical survey) and at first outpatient follow-up (follow-up survey). The aim of this study was to evaluate data originating from NREV in terms of comparability, completeness, accuracy and timeliness. Methods: Coding
Background: Alpha-synuclein (asyn) has been shown to play an important role in the neuropathology of Parkinson's disease (PD). In the diseased brain, classic intraneuronal inclusions called Lewy bodies contain abnormal formations of asyn protein which is mostly phosphorylated at serine 129 (pS129 asyn). This suggests that post-translational modifications may play a role in the pathogenic process.
The budding yeast Naumovozyma castellii (syn. Saccharomyces castellii) has been included in comparative genomics studies, functional analyses of centromere DNA elements, and was shown to possess beneficial traits for telomere biology research. To provide useful tools for molecular genetic approaches, we produced stable haploid heterothallic strains from an early ancestral strain derived from the N
An applied kHz optical remote sensing system is implemented to determine the flight direction of an insect with respect to wind direction, and its relative size using near- and shortwave infrared light in situ.
Objectives. The Nordic Consortium for Acute Type A Aortic Dissection (NORCAAD) is a collaborative effort of Nordic cardiac surgery centers to study acute type A aortic dissection (ATAAD). Here, we outline the overall objectives and the design of NORCAAD. Design. NORCAAD currently consists of eight centers in Denmark, Finland, Iceland and Sweden. Data was collected for patients undergoing surgery f
Monitoring and evaluation of malaria control in pregnancy is essential for assessing the efficacy and effectiveness of health interventions aimed at reducing the major burden of this disease on women living in endemic areas. Yet there is no currently integrated strategic approach on how this should be achieved. Malaria control in pregnancy is formulated in relation to epidemiological patterns of e
Hitherto unobserved long-lived massive particles with electric and/or colour charge are predicted by a range of theories which extend the Standard Model. In this Letter a search is performed at the ATLAS experiment for slow-moving charged particles produced in proton-proton collisions at 7 TeV centre-of-mass energy at the LHC, using a data-set corresponding to an integrated luminosity of 34 pb(-1)
OBJECTIVE: People with disabilities find it harder to enter the labour market than people without disabilities and those with a mental illness are, in relation to people with other disabilities, employed at an essentially lower extent. Many are effectively helped by the vocational rehabilitation model Individual Placement and Support (IPS), but there are still many individuals left in undesired un
We report on fabrication and optical characterization of GaAs nanopillar (NP) arrays, obtained using a combination of low-cost mask generation by self-assembled silica particles (nanosphere lithography) and dry etching. Tapered structures (conical and frustum NP arrays) are fabricated by appropriate optimization of process parameters. Significant suppression of surface reflectance is observed for
We have studied the influence of three different fullerene derivatives on the charge generation and recombination dynamics of polymer/fullerene bulk heterojunction (BHJ) solar cell blends. Charge generation in APFO3/[70]PCBM and APFO3/[60]PCBM is very similar and somewhat slower than charge generation in APFO3/[70]BTPF. This difference qualitatively matches the trend in free energy change of elect
In the present paper we deal with integrators relying on Finite Elements in time for general hyperelastic models which guarantee the conservation of the momentum maps as well as of the total energy within the calculation accuracy. In the isotropic case, eigenvalue-based constitutive laws are, on the one hand, very significant to model the behaviour of various materials. On the other hand, it will
A new class of chiral non-racemic gamma- and delta-amino alcohols based on bicyclo[2.2.1]heptane and bicyclo[2.2.2]octane have been synthesized and used as catalysts in the asymmetric diethylzinc addition to benzaldehyde. (C) 2008 Elsevier Ltd. All rights reserved.
This work compares the extent of linear response regions from standard time-resolving optical detectors for phosphor thermometry. Different types of photomultipliers (ordinary and time-gated) as well as an avalanche photodiode were tested and compared using the phosphorescence decay time of cadmium tungstate (CdWO4). Effects originating from incipient detector saturation are revealed as a change i
Systems based on bag-of-words models from image features collected at maxima of sparse interest point operators have been used successfully for both computer visual object and action recognition tasks. While the sparse, interest-point based approach to recognition is not inconsistent with visual processing in biological systems that operate in 'saccade and fixate' regimes, the methodology and emph
We show that the principally two-dimensional (2D) scanning tunneling microscope (STM) can be used for imaging of 1D micrometer high free-standing nanowires. We can then determine nanowire megahertz resonance frequencies, image their top-view 2D resonance shapes, and investigate axial stress on the nanoscale. Importantly, we demonstrate the extreme sensitivity of electron tunneling even at very hig
We use one-loop Heavy Meson Chiral Perturbation Theory (HMChPT) as well as a relativistic formulation to calculate the chiral logarithms m(pi)(2) log (m(pi)(2)/mu(2)) contributing to the formfactors of the semileptonic B -> pi decays at momentum transfer q(2) away from q(max)(2) = (m(B) - m(pi))(2). We give arguments why this chiral behaviour is reliable even in the energy regime with hard or fast
Through the integrated framework of participation theory and political economy, this article analyzes participatory opportunities in the virtual world Habbo Hotel, and how participation is constrained and framed by the producer’s commercial strategies, which are based on advertising and sales of virtual goods. The study also looks into the ways in which the producer Sulake Corporation discursively
The interactions of the ECM (extracellular matrix) protein asporin with ECM components have previously not been investigated. Here, we show that asporin binds collagen type I. This binding is inhibited by recombinant asporin fragment LRR (leucine-rich repeat) 10-12 and by full-length decorin, but not by biglycan. We demonstrate that the polyaspartate domain binds calcium and regulates hydroxyapati
In order to understand ritual in the past, archaeology has long relied on theories developed in other disciplines. While these theories, which often rely on written or oral information, have added many important dimensions to our interpretation of the archaeological record, they have often proven difficult to successfully articulate with the archaeological sources. Moreover, archaeology has tended
