Introduction: Intervention thresholds (ITs), the 10-year hip fracture risk at which treatment can be considered to be cost-effective, have previously been estimated for Sweden and the UK. Objective: The aim of this study was to provide a Markov cohort model platform for a multinational estimation of thresholds at which intervention becomes cost-effective and to investigate and determine the main f
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
A cheap value-added product, the protein fraction of barley spent grains is proposed as a source of a potential and economical cultivation medium. We showed that medium composed of protein fraction extract allows the isolation of actinobacteria, especially Streptomyces, from soil samples, and enhances the sporulation. It was used for the screening and production of the biologically active substanc
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
The release of two compositionally different solutes from a composite gel composed of two different populations of microgel particles embedded in a single bulk gel matrix is described, showing the potential of the "plum-pudding gel" as a multifunctional platform for controlled surface release. One hydrophobic solute (pyrene) and one hydrophobic and charged solute (rhodamine 123) were chosen as the
OBJECTIVES: The purpose of this study was to estimate retrospectively the costs of health care resources used in the Malmö Preventive Project, Sweden and estimate the costs of in-patient care that were avoided because of early intervention. SETTING AND SUBJECTS: A large-scale community intervention programme was conducted from 1974 to 1992 in Malmö, Sweden with the aim of reducing morbidity and mo
We analyzed the cumulative revision rate in 1,474 patients (1,660 hips) operated on with a cemented Scan Hip Classic I prosthesis from November 1983 to January 1994 at Lund University Hospital. The revision rate was analyzed for 3 diagnoses--arthrosis, rheumatoid arthritis and complication after a hip fracture--and for 2 head diameters--22 and 32 mm. Until January 1996, 36 hips were revised: 31 be
Introduction: Cyclic adenosine 3’5’-monophosphate (cAMP) and cyclic guanosine 3’5’-monophoshpate (cGMP) are critical intracellular second-messengers involved in the transduction of a wide variety of extracellular stimuli, including peptide hormones, growth factors, cytokines, neurotransmitters and light. These messengers modulate many fundamental biological processes, including growth, differentia
So-called child neuropsychiatric disorders (ADHD/DAMP, autism spectrum disorders, Tourette's syndrome) are being recognized with increasing frequency in child and adolescent psychiatry. Through follow-up studies, case reports and autobiographical accounts it has become evident that these disorders often persist into adulthood, and the need for diagnostic evaluation of adults is increasing. The Neu
This article outlines an experimental and theoretical comparison between the fib 2000 model for elastic modulus of normal concrete, NC, and HPC and 144 laboratory tests. Two dimensions of specimen were studied (diameters 56 and 100 mm) and one climate (20 degreesC, sealed or with ambient relative humidity, RE, 60%). The age dependence did not seem to be well correlated between the derived and the
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
Fluorescence in situ hybridization (FISH) with a locus-specific dual DNA probe (LSI EGR-1SO/D5S23SG) for chromosome 5 was used in combination with morphology to study bone marrow cell lineage involvement of the abnormal chromosomal clone in 13 patients with deletion 5q[del(5q)], either as a sole aberration or as part of a complex karyotype, and in six cases with monosomy 5 by metaphase cytogenetic
The photoreceptor cells of the nocturnal spider Cupiennius salei were investigated by intracellular electrophysiology. (1) The responses of photoreceptor cells of posterior median (PM) and anterior median (AM) eyes to short (2 ms) light pulses showed long integration times in the dark-adapted and shorter integration times in the light-adapted state. (2) At very low light intensities, the photorece
Objective. To evaluate the longitudinal development of the tricuspid gradient (TG) for screening for pulmonary arterial hypertension (PAH) in systemic sclerosis (SSc). Methods. Doppler echocardiography was performed 506 times in order to estimate TG in 227 consecutive patients with SSc. The value of biochemical markers for predicting TG levels and development was assessed through analyses of pro-b
The reported rate of detection of Chlamydia pneumoniae DNA within atherosclerotic lesions by PCR varies between 0 and 100%. In this study, identical sets of coded experimental atheroma samples (n = 15) and spiked controls (n = 5) were analyzed by 16 test methods in nine centers by means of PCR. The positive controls were correctly identified to levels of 1, 0.1, and 0.01 inclusion bodies of C. pne
A new system for photon induced fluorescence spectroscopy (PIFS) at the gas phase photoemission beamline (Elettra, Trieste) is described. It consists of a novel non-dispersive detector for VUV photons and a spectrometer for UV/visible light with cooled CCD detector. To illustrate the performance of the apparatus, the fluorescence decay of the doubly excited states of helium below the N = 2 ionizat
