A new work organization was introduced in administrative surveying work in Sweden during 1998. The new work organization implied a transition to a client-centred team-based organization and required a change in competence from specialist to generalist knowledge as well as a transition to a new information technology, implying a greater integration within the company. The aim of this study was to f
Aims/hypothesis: The genetic architecture of model- derived parameters of beta cell function has never been assessed. Therefore, we estimated heritability (h(2)) for model- derived phenotypes of insulin secretion in twins. Methods: Thirty-three monozygotic (MZ) and 23 dizygotic (DZ) twin pairs from the Finnish Twin Cohort Study underwent OGTT (plasma glucose/C-peptide at 0, 30, 60, 90 and 120 min)
The probability distribution of the height of global maximum for a Gaussian random field evolving in time is studied. In particular, the effect of spreading is studied and the role of the wave kinematics is discussed. It is observed that taking into account time dynamics of spatial characteristics results in distributions different from those obtained for the static case. The results are illustrat
Post-operative hyperglycaemia is important with regard to outcomes of surgical operations. It affects postoperative morbidity, length of hospital stay, and mortality. Poor peri-operative blood glucose control leads to a higher risk of post-operative complication. Insulin resistance as a cause of post-operative hyperglycaemia has been blamed for some time. Nitric Oxide (NO) is produced by nitric ox
Objective: A method study of the mfVEP technique to establish a standardised way to identify stable response components from small areas in all parts of the visual field and a test-retest reliability study. Methods: MfVEP was recorded from 26 healthy volunteers. Results: Two response components could be clearly identified. The latencies corresponded to those of the traditional VEP response (N75 an
Aqueous aerosols produced by nebulizers used in clinical situations can rapidly change size as the patient inhales. This is caused by air with a relative humidity (RH) lower than inside the nebulizer being entrained and mixed with nebulized aerosol during the inhalation maneuver. A way to assess the change in size is to measure the aerosol in a test method that reflects the clinical situation. The
Background Several studies among dermatological patients have shown a link between various chronic dermatological diseases and mental morbidity. Objectives To explore the association between self-reported skin morbidity and psychosocial factors in the general population. Methods This population-based cross-sectional study is part of the Oslo Health Study conducted during 2000–2001. All individua
Sand steppe is a rare vegetation type on sandy soils in southeastern Sweden with Koeleria glauca and Dianthus arenarius as the most characteristic plant species. The sand steppe areas ill eastern Skane were surveyed during 2004 and 2005. The vegetation composition was monitored and related to die pH and lime content Many sand steppes are close to acidification as indicated by low lime content ill
Aqueous extract of Clinopodium vulgare L. showed strong antitumour activity when tested in vitro on A2058 (human metastatic melanoma), HEp-2 (epidermoid carcinoma, larynx, human) and L5178Y (mouse lymphoma) cell lines-6 h after treatment disintegration of the nuclei and cell lysis started. Applied at a concentration of 80 microg/ml it reduced the cell survival to 1.0, 5.6 and 6.6%, respectively. T
A microwave-assisted extraction (MAE) method has been developed for determination of zearalenone in wheat and corn by LC-MS with an atmospheric pressure chemical ionization interface (APCI). Matrix effects were minimized by use of matrix-matched standard curves for quantification of the analyte. The limit of quantification (LOQ) of the method was 30 ng g(-1) in wheat and 20 ng g(-1) in corn. The r
The effect of various processing methods on physico-chemical properties of sword bean starch was studied. Seed grits and flour were cooked with and without soaking, wet-autoclaved, and roasted. The changes in starch associated with these processing methods were studied by observing changes in granular structure, water solubility index, water absorption index, molecular size distribution and the de
Recent experimental evidence indicates that neurotrophic factors play a role in the pathophysiology of epilepsy. The objective of this study was to explore whether signaling through one of the glial cell line-derived neurotrophic factor family receptors, GFRα2, influences the severity of kindling-evoked, rapidly recurring seizures and the subsequent development of permanent hyperexcitability. We a
Arctic foxes are evaluated as seed dispersal vectors for Greenlandic plant species through a feeding experiment with subsequent scat analysis and germination test. Seeds of 22 common species with different morphology were tested. Passage time ranged between 4 and 48 hours. No significant differences was detected in passage time for seeds with different morphology. Cerastium alpinum and Stellaria l
The aim of the study was to characterize the relationship between the pharmacolkinetics of methotrexate in serum and concentrations in the cerebrospinal fluid, and to analyse the association to risk of a central nervous system relapse in children with acute lymphoblastic leukaemia. In this retrospective study, 353 children with acute lymphoblastic leukaemia treated with high-dose methotrexate acco
Double-stranded (ds) DNA from salmon testes has been incorporated into PVA hydrogels obtained by a technique of repeated freezing and thawing. The cryogels obtained are free of potential toxic species like chemical cross-linkers, and consequently, they can be used in pharmaceutical or medical applications. These cryogels show a good mechanical resistance and a white and opaque appearance caused by
In this study, mould growth on wood was investigated by image analysis. The studied parameters were drying and heat-treatment temperatures (20-210°C), original and resawn surface and different wood species (spruce and larch). Small specimens—some of which were inoculated with a spore suspension—were stored under humid conditions and photographed once a week. Mould growth was assessed by image anal
Human ECV304 cells respond reproducibly by tube formation to complex basement membrane matrices. Laminins are major glycoproteins of basement membranes. We therefore studied the ability of ECV304 cells to attach to defined laminin isoforms and to fibronectin, and identified the involved laminin receptors. The cells bound poorly to fibronectin, to some extent to laminin-1, whereas laminin-2/4 and -
