Evaluation of prophylactic treatment of haemophilia requires sensitive methods. To design and test a new magnetic resonance imaging (MRI) scale for haemophilic arthropathy, two scales of a combined MRI scoring scheme were merged into a single scale which includes soft tissue and osteochondral subscores. Sixty-one joint MRI's of 46 patients with haemophilia were evaluated by four radiologists using
PURPOSE: Accumulation of oxidized LDL in the arterial wall is believed to play a key role in the development of atherosclerosis. Experimental studies have identified the presence of immune responses against epitopes in oxidized LDL that protects against atherosclerosis. We have produced human recombinant IgG against one of these epitopes (aldehyde-modified apoB-100 amino acids 661-680) and demonst
Objective: The European System for Cardiac Operative Risk Evaluation (EuroSCORE) is used to identify patients at high risk for aortic valve replacement (AVR) in whom alternative procedures, such as trans-catheter aortic valve implantation (TAVI), may be appropriate. The aim of the present study was to calibrate and validate the EuroSCORE for different cardiac surgery procedures to improve patient
This study describes and validates a new method for automatic segmentation of left ventricular mass (LVM) in myocardial perfusion SPECT (MPS) images. This is important for estimating the size of a perfusion defect as percentage of the left ventricle. METHODS: A total of 101 patients with known or suspected coronary artery disease underwent both rest and stress MPS and MRI. A new automated algorith
The natural radiative lifetime of the 3s 4p 1P1 level of neutral magnesium was measured by pulsed level-crossing spectroscopy at the short excitation wavelength of 202.6 nm. We obtained tau = 13.4(5) ns for this state, strongly deviating from a previous beam-foil result, but in good agreement with a multi-configuration Hartree-Fock calculation. A discussion of the applicability of the pulsed Hanle
Scand J Caring Sci; 2011 Online self-help tools for the relatives of persons with depression - a feasibility study Background: The Internet's potential as health care tool should be explored. Aim: One objective was to determine the feasibility of constructing a digitally based tool through an iterative design process in cooperation with potential users. The tool's purpose is to alleviate hardships
We present a portable system for non-invasive, simultaneous sensing of molecular oxygen (O-2) and water vapor (H2O) in the human paranasal cavities. The system is based on high-resolution tunable diode laser spectroscopy (TDLAS) and digital wavelength modulation spectroscopy (dWMS). Since optical interference and non-ideal tuning of the diode lasers render signal processing complex, we focus on Fo
Two different mathematical methods of implementing a detailed kinetic soot model have been employed in this work. The theoretical description of the soot modeling employed in this work is divided into three parts. Initially a detailed kinetic soot model is described from a chemistry and physics perspective. The soot model is then elaborated into mathematical form, starting with the formulation of
AIMS: To assess the Edinburgh Postnatal Depression Scale (EPDS), a self-administered questionnaire created to screen for symptoms of postpartum depression in the community, from an epidemiological and ethical perspective. Screening, as the practice of investigating apparently healthy individuals to detect unrecognised disease or its precursors, has interpretation problems and is complicated by del
In 1995, Best et al. published a formula for the exact bit error probability for Viterbi decoding of the rate R=1/2, memory m=1 (2-state) convolutional encoder with generator matrix G(D)=(1 1+D) when used to communicate over the binary symmetric channel. Their method was later extended to the rate R=1/2, memory m=2 (4-state) generator matrix G(D)=(1+D^2 1+D+D^2) by Lentmaier et al. In this paper
The international legal framework regulating the problem of human trafficking contains the presumption that the return of victims of human trafficking to their countries of origin is the standard resolution for their cases. However, victims might have legitimate reasons for not wanting to go back. For those victims, resort to the legal framework of the European Convention on Human Rights could be
This article aims at introducing to a wider circle a complementary research approach in user oriented work. Its most fundamental part is the use of technology as a tool for capturing the needs, wishes and dreams of a user. The incitement for us to start developing this method was an experience based, serious, questioning of conventional methods such as interviews, questionnaires, etc, and their c
