Long-Term Outcome of Fractures of the Thoracic and Lumbar Spine

Popular Abstract in Swedish Skador på kotor i bröst- eller ländryggen efter en olycka kan omfatta allt ifrån en diskret skelettskada till en kotfraktur kombinerad med skador på diskar (mellankotskivor), leder, ligament, mjukdelar, nervrötter och (eller) ryggmärg. En kotfraktur kan därför leda till allt från lättare övergående besvär till kronisk smärta och invaliditet. Även patientens ålder, kön oFrom the radiographic archives at the Malmö University Hospital, Malmö, Sweden, we identified children below age 16 years (n=74) and adolescents between 16 to 18 years (n=40) with a clinically and radiographically diagnosed thoracic or lumbar vertebral fracture between 1950 to 1971 (with exception of two years of missing radiographs), and all adults above age 18 years (n=39) with a non-operatively

En bloc vs transhiatal esophagectorny for stage T3 N1 adenocarcinorna of the distal esophagus

Hypothesis: En bloc esophagectomy (EBE) provides improved survival over transhiatal esophagectomy (THE) in patients with similarly sized transmural tumors (T3) and lymph node metastases (N1). Design: A retrospective case-control study of 2 methods of esophageal resection for cancer. Setting: University hospital (tertiary referral center for esophageal disease). Patients: There were 49 patients (27

Influence of defects on the lattice constant of GaMnAs

We study the influence of the major compensating defects As antisites and Mn interstitials known to occur in the GaMnAs ferromagnetic semiconductor on its structural properties. Our experimental results show that there is a balance between Mn interstitial and As antisite defects, leading to the reduced density of one type of defect upon increasing the density of the other defect. Significant diffe

Short-Pulse Laser Spectroscopy for Combustion Diagnostics - Laser-Induced Fluorescence of Polyatomic Molecules and Developments in Measurement and Evaluation

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

Correlating Laboratory and Field Tests of Creep in High-Performance Concrete.

This article outlines experimental laboratory and field studies on creep of young or mature High Performance Concrete, HPC, carried out between 1991 and 1999. For this purpose about 400 cylinders made out of 8 mix compositions of HPC were studied in the laboratory. Half the number of HPC was sealed; half of the studies were carried out on air-cured HPC. Parallel tests on strength, internal relativ

A Sequel to: Analytical and Experimental Investigation of Stability of Frames and Arches Subjected to Follower Forces

The displacement method developed for the analysis of the stability of circular arches in paper (1) excludes the mass of the arch. To overcome the shortcomings of paper (1) in this respect, the method of initial parameters is employed below in the derivation of the frequency equations of a circular arch subjected to a nonconservative follower force Q at the free end (Figs 1, 2) and taking into acc

Gatekeeper pathways and cellular background in the pathogenesis and therapy of AML

Acute myelogenous leukemia (AML) is characterized by the accumulation of immature cells due to disturbed differentiation and proliferation of the myeloid lineage. Genetic alterations affecting transcription factors and receptor tyrosine kinases have been identified in AML and causally linked to the disease. The goal of this review is to address the role of the different genetic alterations in self

Pelvic motion in trans-femoral amputees in the frontal and transverse plane before and after special gait re-education.

Using a special gait re-education programme, combining methods in physiotherapy with a psychological therapeutic approach to integrate the prosthesis with normal movements and to increase body awareness, the authors studied unilateral trans-femoral amputees aged 16-60 years with trauma or tumour as causes. In their service area they found 16 such current prosthetic users with at least 2 years of p

Determination of 5-hydroxy-N-methylpyrrolidone and 2-hydroxy-N-methylsuccinimide in human urine

A method for simultaneous determination of 5-hydroxy-N-methylpyrrolidone and 2-hydroxy-N-methylsuccinimide in urine is described. These compounds are metabolites of N-methyl-2-pyrrolidone, a powerful and widely used organic solvent. 5-Hydroxy-N-methylpyrrolidone and 2-hydroxy-N-methylsuccinimide were purified from urine by adsorption to a C8 solid-phase extraction column and then elution by ethyl

High transverse momentum physics at the large hadron collider

This note summarizes many detailed physics studies done by the ATLAS and CMSCollab orations for the LHC, concentrating on processes involving the production of high mass states. These studies show that the LHC should be able to elucidate the mechanism of electroweak symmetry breaking and to study a variety of other topics related to physics at the TeV scale. In particular, a Higgs boson with coupl

Credit risk - A structural model with jumps and correlations

We set up a structural model to study credit risk for a portfolio containing several or many credit contracts. The model is based on a jump-diffusion process for the risk factors, i.e. for the company assets. We also include correlations between the companies. We discuss that models of this type have much in common with other problems in statistical physics and in the theory of complex systems. We

Association between maternal pre-existing or gestational diabetes and health problems in children

There is general consensus that children of women with pre-existing diabetes mellitus (PDM) have an increased risk of malformations and neurodevelopmental problems. Whether this is also true for children of women with gestational diabetes mellitus (GDM) is a matter of debate. This study investigated inpatient hospital care up to 10 y of age of children born to GDM and PDM women as a rough estimate

Resonance-enhanced two-photon ionization (RETPI) of Sih II and an anomalous, variable intensity of the lambda-1892 Si III] line in the Weigelt blobs of eta Carinae

Context. The Si III] 1892 angstrom intercombination line shows an anomalously high intensity in spectra of the radiation-rich Weigelt blobs in the vicinity of Eta Carinae. The line disappears during the 100 days long spectral events occurring every 5.5 years. Aims. The aim is to investigate whether resonance-enhanced two-photon ionization (RETPI) is a plausible excitation mechanism for the Si III]

Temporal patterns of occurrence and transmission of the blood parasite Haemoproteus payevskyi in the great reed warbler Acrocephalus arundinaceus

We studied the prevalence and intensity of the haemosporidian blood parasite Haemoproteus payevskyi in great reed warblers at Lake Kvismaren (6 years) and Lake Segersjo (3 years) in Sweden. Based on microscopic inspection of slides from 282 adult birds, 20.6% showed infection of H. payevskyi in circulating red blood cells in at least 1 year. For parasite prevalence, there was no difference between

Effect of apple cider vinegar on delayed gastric emptying in patients with type 1 diabetes mellitus: a pilot study.

ABSTRACT: BACKGROUND: Previous studies on healthy people show that vinegar delays gastric emptying and lowers postprandial blood glucose and insulin levels. The aim of this study was to investigate the effect of apple cider vinegar on delayed gastric emptying rate on diabetes mellitus patients. METHODS: Ten patients with type 1 diabetes and diabetic gastroparesis, including one patient who had und
