To assess the value of ECG-gating for the diagnosis of myocardial infarction using myocardial perfusion scintigraphy (MPS) and an artificial neural network. A total of 422 patients referred for MPS were studied using a one day Tc-99m-tetrofosmin protocol. Adenosine stress combined with submaximal dynamic exercise was used. The images were interpreted by one of three experienced clinicians and thes

The reaction rate coefficient k(CH3Br + OH) has been determined in the temperature range 298-373 K, using pulse radiolysis/UV kinetic spectroscopy, and at 298 K using a relative rate method. The Arrhenius expression obtained from a fit to the experimental results is (2.9 +/- 0.9) x 10(-12) exp(-(1230 +/- 125)/T) cm(3) molecule(-1) s(-1), which is greater than the expression currently recommended.

Popular Abstract in Swedish Gliom är den vanligaste typen av hjärntumörer hos vuxna. Den mikroskopiska klassificeringen av de olika formerna av gliom är subjektiv och i vissa fall t.o.m. felaktig, vilket leder till klinisk oklarhet som kan hindra utvecklingen av terapier som riktas mot speciella egenskaper som kännetecknar speciella typer av gliom. EGFR och PDGFRA är en cellreceptor som har en cenGlioma is the most common type of primary tumor in the adult central nervous system (CNS). However, the current classification of gliomas is highly subjective and even inaccurate in some cases, which leads to clinical confusion and hinders the development of targeted therapies. EGFR and PDGFRA play crucial roles in glia development and glioma pathogenesis. In this thesis we aim to establish a glia

The Genuine Progress Indicator (GPI) is a tool for measuring the wellbeing of an economy. The question of how to include the use of renewable energy sources is important when estimating the GPI for an economy highly dependent on renewable energy like Iceland. An analysis of GPI estimations showed that the use of renewable energy sources is reflected by the subtraction of the use of non-renewable o

INTRODUCTION: Idiopathic Parkinson's disease (PD) is a progressive neurodegenerative disorder related to α-synuclein misfolding and aggregation. For this reason, it belongs to the family of 'synucleinopathies', which also includes some other neurological diseases. Although imaging and ancillary investigations may be helpful in the diagnostic workup, the diagnosis of PD mostly relies on the clinici

Despite important applications in unsteady Stokes flow, a Fredholm second kind integral equation formulation modeling the first Dirichlet problem of the modified biharmonic equation in the plane has been derived only recently. Furthermore, this formulation becomes very ill-conditioned when the boundary is not smooth, say, having corners. The present work demonstrates numerically that a method call

The rapid growth of cities requires effective management of transport demand and restructuring of transport systems to address the needs of growing urban populations in an environmentally, socially and economically sustainable way. In recent years, car sharing has emerged as an alternative to owning cars in cities, which has potential to bring environmental gains and address social considerations.

This article explores the intersection between the indiscernible forces of urbanisation and the materialisation of architectural form. Taking the design of architectural concept for an Accessory Dwelling Unit (ADU) at Råå in Sweden as an applied research project, the article argues that new techniques are needed to analyse interactions between artistic intentionality and indiscernible forces, and

METHODS: Patients with asthma and/or COPD who switched to BF Spiromax were matched (1:3) with non-switchers. Data were obtained from the Optimum Patient Care Research Database and Clinical Practice Research Datalink in the UK. The primary end point was the proportion of patients achieving disease control (using the risk domain control (RDC) algorithm); secondary end points were: exacerbation rate,

The FinEstBeaMS beamline is under construction at the 1.5 GeV storage ring of the MAX IV Laboratory at Lund, Sweden. It has been designed to cover an unusually wide energy range from ultraviolet (4.3 eV) to soft X-rays (1000 eV) but experiments will also be possible at the Mg and Al Kα energies. Instead of having two different insertion devices and optical schemes for low and high photon energy re

Previous studies about the trends and sources of PV soft cost reduction have only offered a limited understanding of systemic aspects that drive this development. Drawing on concepts of sectoral innovation system theory, this study analyzes the evolution of the German PV sectoral system since the early 1990s, focusing specifically on key processes associated with the deployment of building-sited P

The advent of inexpensive consumer virtual reality equipment enables many more researchers to study perception with naturally moving observers. One such system, the HTC Vive, offers a large field-of-view, high-resolution head mounted display together with a room-scale tracking system for less than a thousand U.S. dollars. If the position and orientation tracking of this system is of sufficient acc

A search is conducted for both resonant and non-resonant high-mass new phenomena in dielectron and dimuon final states. The search uses 3.2fb−1 of proton–proton collision data, collected at s=13TeV by the ATLAS experiment at the LHC in 2015. The dilepton invariant mass is used as the discriminating variable. No significant deviation from the Standard Model prediction is observed; therefore limits

Background: The pathophysiology of neurodegeneration is complex. Its diagnosis requires an early identification of sequential changes in several hallmarks in the brains of affected subjects. The presence of brain pathology can be visualized in the cerebrospinal fluid (CSF) by protein profiling. It is clear that the field of Alzheimer’s disease (AD) will benefit from an integration of algorithms in

We evaluated the clinical utility of the Swedish SCARED-R in child- and adolescent psychiatric outpatients (n = 239) and validated it against Longitudinal Expert All Data (LEAD) DSM IV diagnoses based on the Children’s Schedule for Affective Disorders and Schizophrenia (KSADS) and subsequent clinical work-up and treatment outcome. The SCARED-R total score and subscales had acceptable sensitivity/s

Introduction The spatial peaks QRS-T angle has been shown to differentiate adult patients with hypertrophic cardiomyopathy (HCM) from controls. We hypothesized that the spatial peaks QRS-T angle would, in isolation, be more accurate than the Italian 12-lead ECG Pre-participation Screening criteria or the Seattle criteria for detecting hypertrophic cardiomyopathy (HCM) in pediatric patients.
