Right ventricular volumes and ejection fraction are challenging to assess by echocardiography, but are well established as functional and prognostic parameters. Three-dimensional (3D) echocardiography has become widespread and relatively easy to use, making calculation of these parameters feasible in the large majority of patients. We review past attempts to estimate right ventricular volumes, cur
BACKGROUND: Topical negative pressure (TNP) therapy is increasingly used in open abdomen management. It is not known to what extent this pressure propagates through the dressing to the bowel surface, potentially increasing the risk of bowel fistula formation. The present study in a porcine model was designed to evaluate pressure propagation. METHODS: A commercially available TNP therapy system (AB
Abstract An N-Heptane mechanism and a Methane/Propane mechanism have been reduced by an Automatic Reduction Tool (ART) and simulated with two different solver combinations, which solve the set of ordinary differential equations governing the time evolution of the species simultaneously with solving algebraic equations for species that can be considered to be in quasi steady state. The most succes
Based on an ongoing research project in which we explore practices, strategies andvisions within feminist activism in a Swedish context, this paper emerges from experiencesduring fieldwork with feminist activist groups. Focusing on tensions and contradictionsencountered during fieldwork, this article problematizes the social and emotional dimen-sions of research. Through a discussion of our intera
BACKGROUND: The aim of this study was to evaluate the measurement properties of the Arnetz and Hasson seven-item stress questionnaire in order to select high-risk freshmen for a stress and alcohol intervention research project. METHODS: Two complete cohorts of university freshmen at two universities were asked to participate in an intervention study. All subjects responded to seven Visual Analogue

AIMS: To investigate the association between psychosocial work conditions, unemployment and lack of belief in the possibility of influencing one's own health. Design/setting/participants/measurements: The 2000 public health survey in Scania is a cross-sectional postal questionnaire study with a 59% participation rate. In total, 5180 persons aged 18-64 years who belonged to the workforce and the un
A spectral analysis is made of a Schrodinger operator with zero-range potential of a one- or two-dimensional lattice in the resonances of an isolated atom and the spectral properties of the crystal is established
BACKGROUND: The prevalence of osteoporosis with related fragility fractures has increased during the last decades. As physical activity influences the skeleton in a beneficial way, exercise may hypothetically be used as a prophylactic tool against osteoporosis. OBJECTIVE: This review evaluates if exercise-induced skeletal benefits achieved during growth remain in a long-term perspective. DESIGN: P
Acute pancreatitis has an incidence of about 300 per 1 million individuals per year, of which 10-15% of patients develop the severe form of the disease. Novel management options, which have the potential to improve outcome, include initial proper fluid resuscitation, which maintains microcirculation and thereby potentially decreases ischaemia and reperfusion injury. The traditional treatment conce
We have shown previously that the stem cell factor (SCF) receptor undergoes phosphorylation on serine residues following ligand stimulation, and that this phopshorylation is dependent mainly on the activity of protein kinase C (PKC). In the present study, we have further investigated the molecular mechanisms behind SCF-stimulated activation of PKC, and found that SCF does not activate phosphatidyl
Liver microcirculation can be affected by a wide variety of causes relevant to liver transplantation and resectional surgery. Intraoperative assessment of the microcirculation could possibly predict postoperative outcome. The present pilot study introduces laser speckle contrast imaging (LSCI) as a new clinical method for assessing liver microcirculation.
The change of phenotypic traits in domestic animals and crops as a response to selective breeding mimics the much slower evolutionary change in natural populations. Here, we describe that the dominant white phenotype in domestic pigs is caused by two mutations in the KIT gene encoding the mast/stem cell growth factor receptor (MGF), one gene duplication associated with a partially dominant phenoty
The Second International Conference on Particle Induced X-ray Emission (PIXE) and its analytical applications was held in Lund, Sweden, June 9-12, 1980. About a hundred papers were presented, including seven invited talks (PIXE and particle scattering, microbeam analysis (2), applications to aerosols (2) and biological samples (2)). The main impression left by the conference was that both the PIXE
A 21 year old man suffering from ileocecal Crohn's disease since 4 years was admitted with history of progressive, right sided hip and leg pain for 6 months. Extensive, retroperitoneal abscesses, extending into the gluteal and paravertebral muscles were visualized. The patient was treated by intravenous antibiotics and percutaneous drainage. Later, ileocecal resection was performed. Most likely, t
