OBJECTIVE: To determine the diagnostic value of metaiodobenzylguanidine (MIBG) scintigraphy compared with computed tomography (CT) for the localization of phaeochromocytomas in clinical practice. DESIGN: Retrospective comparison between MIBG scintigrams and CT for localization of phaeochromocytomas in all patients successively examined with MIBG scintigraphy in Malmo from 1984 until January 1997.
A model has been formulated for the pyrolysis of wood. This model includes heat and mass transfer. Heat transfer in the material is assumed to take place by thermal conduction and convection. Mass transfer of volatile pyrolysis products and water vapour occurs under the influlence of gradients in to tal pressure. Pyrolysis is assumed to conform to an Arrheniusfunction, and vaporization occurs at a
The objectives of this study were to describe a population of elderly patients at the beginning of their rehabilitation period as regards subjective well-being and dependence in activities of daily living (ADL). In a Swedish rural county 244 patients aged 65+ who had begun rehabilitation within the last month were targeted. One part of the self-administered Goteborg Quality of Life Instrument and
Background: Obstructed labour is still a major cause of maternal morbidity and mortality and of adverse outcome for newborns in low-income countries. The aim of this study was to investigate the role of individual and health facility factors and the risk for obstructed labour and its adverse outcomes in south-western Uganda. Methods: A review was performed on 12,463 obstetric records for the year
Objective . Low density lipoprotein cholesterol (LDL-C) is an independent and modifiable risk factor for development of cardiovascular disease (CVD). Postprandial lipid metabolism has been linked to CVD, but little is known about the postprandial LDL-C profile in patients with type-2 diabetes (T2DM). We aimed to study the postprandial levels of LDL-C in T2DM patients. Material and methods . After
Objective. Secondary hyperparathyroidism (SHPT) is a common problem among patients with chronic kidney disease (CKD) on haemodialysis. This study was conducted to assess the use, effectiveness and safety of intravenous paricalcitol in haemodialysis patients with various degrees of SHPT. Material and methods. This observational, multicentre, prospective study was conducted in 14 Swedish dialysis ce
A search for long-lived particles is performed using a data sample of 4.7 fb(-1) from proton-proton collisions at a centre-of-mass energy. root s = 7 TeV collected by the ATLAS detector at the LHC. No excess is observed above the estimated background and lower limits, at 95% confidence level, are set on the mass of the long-lived particles in different scenarios, based on their possible interactio
This study investigates several commercial selective catalytic reduction (SCR) catalysts (A–E) for application in a high-temperature (approximately 525 °C) and high-concentration (5000 ppm NO) system in combination with CO2 capture. The suggested process for removing high concentrations of NOx seems plausible and autothermal operation is possible for very high NO concentrations. A key property of
Background: A trial fibrillation (AF) is a common problem in pacemaker patients. We conducted a prospective observational study in patients paced for bradycardia with associated paroxysmal or persistent AF, to determine whether P-wave duration may stratify patients at higher risk for AF recurrences and AF-related hospitalizations. The patients were evaluated for the prevalence, cause, and predicto
Chitosan was chosen as a natural polymer for dispersion of single walled carbon nanotubes (SWNT) based on its ability to efficiently solubilize SWNTs to form a stable dispersion. Moreover, chitosan films deposited on a surface of a glassy carbon (GC) electrode are mechanically stable. Further stabilisation of the chitosan film containing SWNT (CHIT-SWNT) was done by chemical crosslinking with glut
AIMS: Atrial fibrillation cycle lengths can be assessed from right precordial ECG leads and the unipolar oesophageal ECG using a non-invasive method called Frequency Analysis of Fibrillatory ECG. The purpose of this report is to present the results from application of this method in a large group of patients with long-term atrial fibrillation and to examine the differences between patients with 'c
Many of the physiological adaptations evolved in terrestrial invertebrates to resist desiccation have also been shown to enhance the survival of low temperatures. In this study we have examined temporal changes in the physiology of the collembolan Folsomia candida during acclimation to mild desiccation stress (98.2% RH), and how physiological changes correlate with resistance to subsequent cold sh
Popular Abstract in Swedish Förbränning är den viktigaste energikällan på jorden och en ökad förståelse av förbränningsprocesser är väsentlig för att minska miljöfarliga utsläpp och för att öka effektiviteten av förbränningsanläggningar och motorer. För detta ändamål är det viktigt att bestämma bl. a. koncentrationer av ämnen som bildas under förbränningen. Laserbaserade mätmetoder möjliggör berörCombustion is the most important source of energy worldwide. A better understanding of it is essential if pollutant emissions are to be reduced and combustion devices be made more efficient. This requires measurement of physical and chemical combustion parameters. Laser-induced fluorescence (LIF) is widely employed as a laser-diagnostic technique for the detection of combustion species but it suff
Selective dorsal rhizotomy is a surgical procedure with a selective division of posterior spinal nerve rootlets to treat spasticity in children. The extensive surgical procedure with multilevel laminectomies and the nerve root manipulation result in intense pain postoperatively. Two intrathecal (IT) regimes of pain treatment were compared in these children, concerning their pain relief and possibl
Within the framework of the European Land Arctic Physical Processes project and as part of the Danish Research Council's Polar Program, a study on trace gas exchange in a high-arctic ecosystem was conducted in NE Greenland, May-August 1997. On the basis of carbon dioxide flux measurements from three dominant surface types, this paper reports on the upscaling of such measurements from canopy to lan
Background The purpose of these studies was to compare efficacy and toxicity of docetaxel alone with the combination of gemcitabine and docetaxel for treatment of metastatic esophageal carcinoma. Patients and methods These studies enrolled patients with histopathologically verified squamous cell carcinoma or adenocarcinoma of the esophagus or cardia. Between March 1997 and June 1999, 52 patients w
Although the beneficial effect on breast cancer of adjuvant tamoxifen (TAM) is well established, in the series studied by our group this effect seems to have been restricted to patients with steroid receptor (especially progesterone receptor (PgR)) positive tumors. However, as some patients with PgR-positive tumors manifested recurrence despite adjuvant TAM treatment, the question arose whether so
