Core-level spectroscopy and valence-band photoelectron spectroscopy were used to study the Ge(100)2×1 surface dosed with 0.5–100 L H2O at 160 K. It is determined that H2O adsorbs molecularly at 160 K and forms ice. The H2O molecules dissociate into H and OH radicals on the Ge(100)2×1 surface when the sample is heated to 300 K. A simple adsorption model that accounts for the calculated H and OH cov
Problems related to the urogenital tract are common in elderly women. Control of micturition is often impeded and questionnaire-based studies have reported a prevalence of poor control of micturition in about 30% of postmenopausal women. In an ongoing cohort comprising women born between 1935 and 1945, an interim analysis was performed in 1800 women based on an interview and questionnaire. The pre
The objectives are to relate species distributions among 110 non-fertilized grassland ('dry meadow') sites in southeastern Sweden to soil chemical, physical, exposure and management variables using correlation, stepwise regression and factor (PCA) analysis based on quantitative data. It was suggested that soil acidity variables (pH, base saturation, exchangeable Ca, Al, Mn,and Fe), P, K, Mg, and N
Autoantibodies to insulin (IAA) are one of the first markers of the autoimmune process leading to type 1 diabetes (T1D). While other autoantibodies in T1D have been studied extensively, relatively little is known about IAA and their binding specificities, especially after insulin treatment is initiated. We hypothesize that insulin antibodies (IA) that develop upon initiation of insulin treatment d
Semiconductor heterostructures and their implementation into electronic and photonic devices have had tremendous impact on science and technology. In the development of quantum nanoelectronics, one-dimensional (1D) heterostructure devices are receiving a lot of interest. We report here functional 1D resonant tunneling diodes obtained via bottom-up assembly of designed segments of different semicon
One first generation assay (manufactured by Ortho, test I) and 3 second generation anti-HCV ELISAs (manufactured by Ortho, Abbott, and UBI, tests II-IV) were compared. Sera from 4 different sources were used: (1) intravenous drug-users (IVDUs, n = 50), (2) blood donors (n = 1055), (3) all clinical samples from one day of routine anti-HCV testing (n = 89), (4) hemodialysis patients previously found
Occupational exposure to diisocyanates within the plastic industry causes irritation and disorders in the airway. The aim of this study was to develop, validate and characterize a method for the determination of 2,4-toluenediamine (2,4-TDA), 2,6-toluenediamine (2,6-TDA), 1,5-diaminonaphthalene (1,5-NDA) and 4,4'-methylenedianiline (4,4'-MDA) in hydrolysed urine and plasma, and to study the correla
Popular Abstract in Swedish Hur man värderar resultat av kirurgisk behandling av ländryggens degenerativa åkommor är ett stort, komplext och delvis kontroversiellt ämne. Denna avhandling studerar resultatvärdering med olika metoder och instrument, huvudsakligen baserat på resultat från det nationella svenska ländryggskirurgiregistret. Arbete I. Inventering av befintliga instrument i litteraturen No consensus regarding outcomes assessment in spine patients exists. Health-Related Quality of Life (HRQoL) questionnaires are increasingly used. The objective of this thesis was the evaluation of HRQoL measures before and after lumbar spine surgery, and their relation to other evaluation parameters as well as relevance of differences. The patients included were operated on for lumbar spine disor
From August 1999 to April 2001, there was an outbreak of severe eczema at a factory manufacturing medical equipment. A glue, mainly based on the isocyanate dicyclohexylmethane-4,4'-diisocyanate (DMDI), was suspected as being the cause of the problem. 16 workers with recent episodes of eczema were patch tested with a standard series, an isocyanate series and work material. The latter consisted of,
Using double-label in situ hybridization, we have explored the possibility that individual CNS neurones can co-express mRNAs for the high-affinity receptors of brain-derived neurotrophic factor and neurotrophin-3, TrkB and TrkC, respectively. The vast majority of TrkC mRNA-containing neurones in the hippocampal formation and cerebral cortex were also labelled for TrkB mRNA. Cells expressing only T
The therapeutic application of siRNA shows promise as an alternative approach to small-molecule inhibitors for the treatment of human disease. However, the major obstacle to its use has been the difficulty in delivering these large anionic molecules in vivo. In this study, we have investigated whether siRNA-mediated knockdown of p38 MAP kinase mRNA in mouse lung is influenced by conjugation to the
The aim of the present study was to compare cellular and noncellular components of bronchoalveolar lavage fluid (BAL) in a group of children with a diagnosis of chronic diffuse parenchymal lung disease (cDPLD) and a group of children without parenchymal lung disease undergoing BAL for various clinical indications (control group). We evaluated cellular and non-cellular components (total proteins, a
Introduction P-32 phosphate was the first therapeutic radioisotope, used in leukaemia about 70 years ago. Since then, many new agents for haematological proliferations have been introduced successfully. Today there remains a distinct subgroup of elderly patients with polycythaemia vera and essential thrombocythaemia for whom P-32 is the most optimal treatment option, an assertion supported by two
