Research within contingency theory recognizes and postulates the relevance of contextual factors to the design of organizations. Thus organizations are dependent on the environments in which they operate and on the technologies they utilize. Organizations therefore need to process information about their environments and technologies. Information systems, including computerized information sytems,
Lyme borreliosis (LB) is a common and increasing tick-borne disease in Europe. The risk of acquiring a Borrelia infection after a tick bite is not fully known. Therefore, we investigated the incidence of Borrelia infection after a bite by a Borrelia-infected tick and if the Borrelia load and/or the duration of tick-feeding influenced the risk of infection. During 2008-2009, ticks and blood samples
Arbuscular mycorrhizal (AM) fungi and a residue from dry olive cake (DOC) supplemented with rock phosphate (RP) and treated with either Aspergillus niger (DOC-A) or Phanerochaete chrysosporium (DOC-P), were assayed in a natural, semi-arid soil using Trifolium repens or Dorycnium pentaphyllum plants. The effects of the AM fungi and/or DOC-A were compared with P-fertilisation (P) over eleven success
Purpose: To investigate the clinical value of assessment of peripapillary retinal nerve fibre layer (RNFL) thickness with OCT in addition to the evaluation of retinal function measured by full-field electroretinography (ff-ERG) in patients with suspected vigabatrin (VGB)-attributed visual field defects. Methods: Visual fields from adult patients in our clinical follow-up program for VGB medication
A search for the standard model Higgs boson is performed in the diphoton decay channel. The data used correspond to an integrated luminosity of 4.9 fb(-1) collected with the ATLAS detector at the Large Hadron Collider in proton-proton collisions at a center-of-mass energy of root s = 7 TeV. In the diphoton mass range 110-150 GeV, the largest excess with respect to the background-only hypothesis is
To estimate the prevalence and incidence of systemic sclerosis (SSc) in southern Sweden.
The response of tundra plants to enhanced UV-B radiation simulating 15 and 30% ozone depletion was studied at two high arctic sites (Isdammen and Adventdalen, 78 degrees N, Svalbard).The set-up of the UV-B supplementation systems is described, consisting of large and small UV lamp arrays, installed in 1996 and 2002. After 7 years of exposure to enhanced UV-B radiation, plant cover, density, morpho
Standardized intra-abdominal hemorrhage was induced in 7 anesthetized pigs. The resulting hypovolemic shock was treated with pneumatic anti-shock garment (PASG) followed by intra-aortic balloon occlusion. The effects of this treatment on circulation, lung mechanics and gas exchange were studied. Hemorrhage was induced by pulling out sutures introduced in the inferior caval vein. We found that the
Antibodies against type II collagen (anti-CII) are arthritogenic and have a crucial role in the initiation of collagen-induced arthritis. Here, we have determined the dependence of T and B cells in collagen-antibody-induced arthritis (CAIA) during different phases of arthritis. Mice deficient for B and/or T cells were susceptible to the CAIA, showing that the antibodies induce arthritis even in th
Few medications for treating alcohol dependence exist. Greater partnership is needed between academia and the pharmaceutical industry to develop, licence and market efficacious medications for treating alcohol dependence. Methodologies that span the divide between preclinical and large-scale clinical studies need to be developed in order to provide sufficient information on safety, toleration, dru
Objective. To determine the short-term and medium-term risks of cancer in patients receiving antitumor necrosis factor alpha (anti-TNF alpha) therapies that have proven effective in the treatment of chronic inflammatory conditions. Methods. By linking together data from the Swedish Biologics Register, Swedish registers of RA, and the Swedish Cancer Register, we identified and analyzed for cancer o
The aims of this study were (i) to assess the differences between men and women in maximal activities of selected enzymes of aerobic and anaerobic pathways involved in skeletal muscle energy production, and (ii) to assess the relationships between maximal enzyme activities, body composition, muscle cross-sectional area (CSA) and fibre type composition. Muscle biopsies were obtained from the tibial
Popular Abstract in Swedish Molekylärgenetiska och funktionella studier av BCR/ABL1 fusionsgenen: Det finns tre sorters blodkroppar, röda, vita och trombocyter, som alla bildas från gemensamma stamceller i benmärgen. När stamcellerna delar sig bildas det antingen nya stamceller eller förstadier till blodkroppar som efter ytterligare delningar blir till mogna blodkroppar. Ibland uppkommer särskildThe BCR/ABL1 fusion gene is associated with chronic myeloid leukemia and a subgroup of acute lymphoblastic leukemia. The general aim of this thesis was to increase the understanding of BCR/ABL1-induced leukemogenesis by molecular and functional studies of this fusion gene. In Article I, an experimental U937 cell line model with inducible expression of BCR/ABL1 was established and characterized. Ex
PURPOSE: Therapeutic traditions at health care practices (HCPs) influence physicians' adherence to prescription guidelines for specific drugs, however, it is not known if such traditions affect all kinds of prescriptions or only specific types of drug. Our goal was to determine whether adherence to prescription guidelines is a common trait of HCPs or dependent on drug type. METHODS: We fitted sepa
Cerebral ischaemia results in enhanced endothelin B (ETB ) receptor-mediated contraction and receptor protein expression in the affected cerebrovascular smooth muscle cells (SMC). Organ culture of cerebral arteries is a method to induce similar alterations in ETB receptor expression. We hypothesize that rapid and sustained reduction in wall tension/stretch is a possible trigger mechanism for this
PURPOSE From 1995 to 2003, 603 adult patients from Sweden and Norway with metastatic testicular nonseminomatous germ cell tumor (NSGCT) were included prospectively in a population-based protocol with strict guidelines for staging, treatment, and follow-up. Patients with extragonadal primary tumor or previous treatment for contralateral testicular tumor were excluded. The basic strategy was to indi
Patients with systemic lupus erythematosus (SLE) have a markedly increased risk to develop cardiovascular disease, and traditional cardiovascular risk factors fail to account for this increased risk. We used microarray to probe the platelet transcriptome in individuals with SLE and healthy controls, and the gene and protein expression of a subset of differentially expressed genes was further inves
