The interpretation of myocardial perfusion scintigraphy (MPS) largely relies on visual assessment by the physician of the localization and extent of a perfusion defect. The aim of this study was to introduce the concept of the perfusion vector as a new objective quantitative method for further assisting the visual interpretation and to test the concept using simulated MPS images as well as patient

The recent growth in research on "good governance" and the quality of government institutions has been propelled by empirical findings that show that such institutions may hold the key to understanding economic growth and social welfare in developing and transition countries. We argue, however, that a key issue has not been addressed, namely, what quality of government (QoG) actually means at the

Recent work on conditional reasoning argues that denying the antecedent [DA] and affirming the consequent [AC] are defeasible but cogent patterns of argument, either because they are effective, rational, albeit heuristic applications of Bayesian probability, or because they are licensed by the principle of total evidence. Against this, we show that on any prevailing interpretation of indicative co

An intermolecular Pauson-Khand reaction involving a carbohydrate scaffold having a pendant alkyne provides galactose derivatives with a cyclopentenone moiety in the C3-position in up to 85% yield.

The phase equilibria of the Au–In–Ga system were investigated for the first time using Differential Thermal Analysis (DTA), X-Ray Diffractometry (XRD), Energy Dispersive X-ray Spectroscopy (EDS) and Scanning Electron Microscopy (SEM). A new ternary phase (Au2InGa2) with the hexagonal structure (P63/mmc) was discovered which melts incongruently at 394 °C. From the experimental results, several inva

The African continent has been severely affected by the HIV and AIDS pandemic and as a consequence, development is being obstructed. Agriculture and food production systems are changing as a result of the burden of the pandemic. Many farming families are experiencing trauma from morbidity and mortality as well as facing labour losses and exhaustion. To further exacerbate the situation, climate var

This essay examines the film News from Ideological Antiquity (2008) by German filmmaker Alexander Kluge. Kluge has tried to fulfil the dream of Soviet filmmaker Sergei Eisenstein and make a film version of The Capital by Karl Marx. Kluge’s endeavour is discussed within the context of European left wing cinema, and the film analysis is intertwined with a mapping of the reception of the work in Euro

Hematopoietic stem cells (HSCs) reside in the bone marrow (BM) of adult individuals and function to produce and regenerate the entire blood and immune system over the course of an individual's lifetime. Historically, HSCs are among the most thoroughly characterized tissue-specific stem cells. Despite this, the regulation of fate options, such as self-renewal and differentiation, has remained elusi

The title compound, [Cr(C15H14O)(CO)(3)], displays a distorted envelope configuration of the dihydropyrane ring. The dihedral angle between the phenyl and phenylene rings is 50.63 (4)degrees. The Cr-0 atom is coordinated by three CO groups and the phenylene ring of the flavan ligand in an eta(6) mode, with a common arene-to-metal distance

Background: The aim of this study was to explore if a course consisting of lectures combined with simulator training in coronary angiography (CA) could accelerate the early learning curve when performing CA on patients. Knowledge in performing CA is included in the curriculum for the general cardiologist. The method, according to American College of Cardiology and European Society of Cardiology gu

Popular Abstract in Swedish Populärvetenskaplig sammanfattning Född utan ändtarmsöppning – det finns mer hjälp! Varje år föds femtio barn i Sverige utan ändtarmsöppning, så kallad analatresi. De sista 2-3 centimetrarna av ändtarmen saknas liksom ändtarmsöppningen och delar av ringmuskeln. Orsaken tros vara plötsligt uppkomna genförändringar tidigt hos fostret. Starten i livet blir svår eftersom deAbstract: Background : Anorecta l malformation s (ARM) occur in 4: 10000 newborn children with the gender distribut ion 1:1.5 females:males. The reconstruction of ARM, posterior sagiccal anorectal plasty (PSARP), was implemenred worldwide in the late 1980s and therefore the follow-ups are limited. Aims: To assess bowel symptoms in children and adolescents with ARM, operated on with PSARP, and to

This article describes a new Stata command called xtwest, which implements the four error-correction-based panel cointegration tests developed by Westerlund (2007). The tests are general enough to allow for a large degree of heterogeneity, both in the long-run cointegrating relationship and in the short-run dynamics, and dependence within as well as across the cross-sectional units.

Efficient energy production relies on complementary use of crop residues, to enhance the amount of energy obtained per unit biomass. In this frame, sugarcane bagasse (SB) was pretreated and the resulting slurry and liquid fraction served, respectively, for simultaneous saccharification and fermentation (SSF) at high solid concentration (15%), and anaerobic digestion (AD). More specifically, SB was

The dic(9;20)(p13.2;q11.2) is reported to be present in similar to 2% of childhood B-cell precursor acute lymphoblastic leukemia (BCP ALL). However, it easily escapes detection by G-banding analysis and its true prevalence is hence unknown. We performed interphase fluorescence in situ hybridization analyses-in a three-step manner-using probes for: (i) CDKN2A at 9p21, (ii) 20p and 20q subtelomeres

The Starmoen dune field is part of a larger aeolian system in the Jomna and Glomma river valleys in southeastern Norway. It is believed to have formed just after the last deglaciation in the area, but no absolute ages have been available to support this. Here, we present a set of quartz optically stimulated luminescence (OSL) ages from the aeolian sediments and the underlying glacifluvial deposits

Popular Abstract in Swedish Every breath you take – Every move you make Astma och allergier tillhör våra vanligaste folksjukdomar och de har ökat under de senaste fyra decennierna, särskilt bland barn och ungdomar. Under samma period så har inställningen till fysisk aktivitet och olika livsstilsfaktorer i samhället förändrats. Det är allmänt accepterat att fysisk aktivitet är bra for hälsan och viAsthma and allergies are common diseases in adolescents and have increased during the last few decades. All elite level sports activities result in increased risk of asthma and rhinitis regardless of sport practised. Physical activity is at the same time regarded as a health-promoting factor and is recommended both for the prevention and treatment of diseases. The aim of this study was to explore

BACKGROUND: The association of early knee joint laxity with the need for later reconstruction of the anterior cruciate ligament has not been extensively studied. HYPOTHESIS: The grade of knee laxity can be used as an early predictor of the need for later reconstruction. STUDY DESIGN: Cohort study (prognosis); Level of evidence, 2. METHODS: One hundred consecutive patients with an acute arthroscopi
