Waveform Characterization of Atrial Fibrillation Using Phase Information

A novel method for characterization of f-wave morphology in atrial fibrillation (AF) is presented. The method decomposes atrial activity into fundamental and harmonic components, dividing each component into short blocks for which the amplitudes, frequencies, and phases are estimated. The phase delays between the fundamental and each of the harmonics, here referred to as harmonic phase relationshi

Blueberry husks, rye bran and multi-strain probiotics affect the severity of colitis induced by dextran sulphate sodium

Objective. The enteric microbiota is a pivotal factor in the development of intestinal inflammation in humans but probiotics, dietary fibres and phytochemicals can have anti-inflammatory effects. The aim of this study was to evaluate the therapeutic effect of multi-strain probiotics and two conceivable prebiotics in an experimental colitis model. Material and methods. Sprague-Dawley rats were fed

NiFe2O4 and Fe3O4 studied by XMCD and resonant photoemission

X-ray magnetic circular dichroism and resonant photoemission at the Fe and Ni L-2,L-3 edges have been used to investigate the electronic structure of NiFe2O4 (NFO) thin films. The results, when compared to those obtained on Fe3O4, indicate that in a 12 nm NFO film the Ni atoms occupy mainly B sites, as in bulk NFO, and that a decrease in the thickness of the film results in a modi. cation of the n

Common Variants Within Oxidative Phosphorylation Genes Influence Risk of Ischemic Stroke and Intracerebral Hemorrhage

Background and Purpose-Previous studies demonstrated association between mitochondrial DNA variants and ischemic stroke (IS). We investigated whether variants within a larger set of oxidative phosphorylation (OXPHOS) genes encoded by both autosomal and mitochondrial DNA were associated with risk of IS and, based on our results, extended our investigation to intracerebral hemorrhage (ICH). Methods-

Impact on allergic immune response after treatment with vitamin A

Background: Vitamin A may have some influence on the immune system, but the role in allergy modulation is still unclear. Objective: To clarify whether high levels of retinoic acid (RA) affects allergic response in vivo, we used a murine experimental model of airway allergic disease. Methods: Ovalbumin (OVA)-immunization/OVA-challenge (OVA/OVA) and house dust mite (HDM)-immunization/HDM-challenge (

Natural Transfer of Viable Microbes in Space from Planets in the Extra-Solar Systems to a Planet in our Solar System and Vice-Versa

We investigate whether it is possible that viable microbes could have been transported to the Earth from planets in extra-solar systems by means of natural vehicles such as ejecta expelled by comets or asteroid impacts on such planets. The probabilities of close encounters with other solar systems are taken into account as well as the limitations of bacterial survival times inside ejecta in space,

The influence of temporal distance on justice and care morality.

The primary goal of this study was to examine whether changes in the temporal distance of a moral dilemma affect how it is perceived and subsequently resolved. Based on Construal Level Theory (Trope & Liberman, 2003), it was predicted that the relative weight of abstract justice features should increase and the relative weight of concrete care features should decrease with temporal distance. T

Genetic and Epigenetic Characterisation of Breast Tumours

Popular Abstract in Swedish Bröstcancer är den vanligaste cancerformen bland kvinnor i Sverige. Ungefär var tionde kvinna beräknas drabbas av bröstcancer, och i Sverige insjuknar ungefär 7.000 kvinnor årligen. Glädjande nog har överlevnaden förbättrats och nästan 90% lever 5 år efter sin diagnos och cirka två tredjedelar kan anses botade. Trots detta dör cirka 1.500 kvinnor i sjukdomen i Sverige vBreast tumours harbour a large amount of genetic and epigenetic alterations, which are associated with e.g. tumour aggressiveness, prognosis, and response to therapy. The heterogeneity of breast tumours is reflected in the identification of at least five molecular subtypes named basal-like, luminal A, luminal B, HER2-enriched and normal-like, which are believed to originate from different cell typ

Performance Improvements for the Rasterization Pipeline

Performance improvements are always needed in computer graphics. Better performance frees up computational resources which can be used to increase the level of realism in the rendered images. Despite a very rapid development of graphics hardware, we are still far from the point where photo-realistic rendering can be done in real time. Therefore, better algorithms must be developed in order to adva

Miljöanpassad upphandling och innovationsupphandling som styrmedel

Syftet med rapporten har varit att analysera erfarenheterna av miljöanpassad upphandling och innovationsupphandling, samt hur dessa styrmdel kan bidra till uppfyllandet av olika politiska målsättningar. Rapporten redogör bl.a. för målsättningarna för upphandling, betydelsen av en efterfrågedriven innovationspolitik, samt hur upphandling kan samverka med andra styrmedel på miljöområdet.

Detection of intracavitary uterine pathology using offline analysis of three-dimensional ultrasound volumes: interobserver agreement and diagnostic accuracy

Objective To estimate the diagnostic accuracy and interobserver agreement in predicting intracavitary uterine pathology at offline analysis of three-dimensional (3D) ultrasound volumes of the uterus. Methods 3D volumes (unenhanced ultrasound and gel infusion sonography with and without power Doppler, i.e. four volumes per patient) of 75 women presenting with abnormal uterine bleeding at a bleeding

Incidence of and risk factors for neonatal morbidity after active perinatal care: extremely preterm infants study in Sweden (EXPRESS)

Aims: The aim of this study was to determine the incidence of neonatal morbidity in extremely preterm infants and to identify associated risk factors. Methods: Population based study of infants born before 27 gestational weeks and admitted for neonatal intensive care in Sweden during 2004-2007. Results: Of 638 admitted infants, 141 died. Among these, life support was withdrawn in 55 infants becaus

Z boson production in p plus Pb collisions at root S-NN=5.02 TeV measured with the ATLAS detector

The ATLAS Collaboration measures the inclusive production of Z bosons via their decays into electron and muon pairs in p + Pb collisions at root S-NN = 5.02 TeV at the Large Hadron Collider. The measurements are made using data corresponding to integrated luminosities of 29.4 and 28.1 nb(-1) for Z -> ee and Z -> mu mu, respectively. The results from the two channels are consistent and combined to

Quantitative X-ray phase-contrast computed tomography at 82 keV

Potential applications of grating-based X-ray phase-contrast imaging are investigated in various fields due to its compatibility with laboratory X-ray sources. So far the method was mainly restricted to X-ray energies below 40 keV, which is too low to examine dense or thick objects, but a routine operation at higher energies is on the brink of realisation. In this study, imaging results obtained a

Sustainable Well-Being: A Potential Synergy Between Sustainability and Well-Being Research

This article outlines a potential synergy between sustainability and well-being research. Currently aims within well-being and sustainability research focus on increasing well-being. First, sustainability is defined and important concepts within it highlighted, that is, aims, interdependencies, constraints, values and balanced adaptive processes. It is suggested that positioning well-being more cl

Burial in the Swedish-Norwegian Battle Axe Culture : questioning the myth of homogeneity

Since its publication in 1962, Mats P. Malmer’s book Jungneolithische Studien has heavily influenced subsequent work on the Swedish-Norwegian Battle Axe Culture. Malmer characterized burial customs as strictly regulated and conservative. Recent archaeological activity in the province of Scania, southern Sweden, provides us with an augmented empirical basis for testing Malmer’s conclusions. In addi
