The phylogenetic relationships of the lichenised ascomycete family Stereocaulaceae were investigated with partial beta-tubulin, partial glyceraldehyde 3-phosphate dehydrogenase (GAPDH) and SSU rDNA sequence data. Due to the marked length variation in the SSU rDNA sequences, the analyses were performed with direct optimization. The combined analysis of the beta-tubulin, GAPDH and SSU rDNA sequences
Ozone dry deposition measurements were carried out during approximately one year over a flat grass field in Portugal. The results show prominent diurnal and seasonal patterns in deposition flux, dry deposition velocity and surface resistance, especially for the daytime period. Dry deposition velocities vary diurnally from a minimum of 0.1 cm s(-1) during the night to a maximum of 0.7-0.5 cm s(-1)
Insertion of lithium in anatase TiO2, giving LixTiO2, is performed under ultrahigh vacuum (UHV) conditions and studied using synchrotron radiation based electron spectroscopy. Core level photoemission spectra are directly compared to results obtained after electrochemical insertion, illustrating the usefulness of the UHV approach. The growth of a state of mainly Ti 3d character in the band gap is
The exposure to Th-232 from TIG welding with thoriated electrodes has been determined at five different workshops. Welding with both alternating and direct current was investigated. The exposure levels of Th-232 were generally below 10 mBq m(-3) in the breathing zone of the welders. Two samples from AC welding showed significant higher exposure levels, probably due to maladjustment of the TIG weld
The aim of this study was to analyse whether the interleukin-1 (IL-1) and IL-6 gene polymorphisms were associated with the susceptibility of chronic periodontitis. Genomic DNA was obtained from 20 patients with chronic periodontitis and 31 periodontally healthy subjects. All subjects were of North European heritage. The test subjects were kept in a maintenance program after periodontal treatment b
Popular Abstract in Swedish Syftet med denna avhandling är att undersöka mötet mellan den kyrkliga överheten och de olika lokalsamhällena sådant som det tog sig uttryck vid de kyrkliga visitationerna. I fokus står biskopsvisitationerna men även de visitationer som prostarna genomförde tas upp till behandling. Undersökningsområdet är Växjö stift och den tidsmässiga avgränsningen är 1650-1760. De frThe aim of this thesis is to investigate the encounter of the ecclesiastical authorities with the local community, as reflected in the church visitations. The focus is on the bishops' visitations, but there is also a brief examination of the deans' visitations, which are used for a comparison of the two types of inspections. The geographical limit of the study is the diocese of Växjö in southern S
Semenogelins I and II are major coagulum-forming proteins in semen, and they are secreted mainly by the seminal vesicles. These proteins bind Zn2+ and act as substrates for prostate-specific antigen and transglutaminase. A variant semenogelin I lacking 60 amino acids has been described that occurs in different populations with an allele frequency of 1%-3%. To better understand the function of the
The behavior of DNA at different types of interfaces and how the formed structures DNA at an interface could be affected by cationic surfactant has been studied. Particular attention was paid to how the type of cationic surfactant and DNA (single or double stranded and length) affects the compaction/decompaction of DNA. Adsorption of DNA-cationic surfactant complexes is determined by a delicate ba
Nine patients with spondylarthropathy (SpA) (6 with ankylosing spondylitis and 3 with psoriatic arthritis) who had not responded properly to conventional DMARD therapy were treated with 3 infusions (at 0, 2 and 6 weeks) of the TNF alpha inhibitor infliximab (3 mg/kg), in combination with methotrexate. To measure the effect of treatment, patients were evaluated before as well as 8 and 12 weeks afte
We examined the interaction of GABA and the competitive inhibitor SR95531 at human α1β1γ2S and α1β1 GABAA receptors expressed in Sf9 cells. The efficacy and potency of inhibition depended on the relative timing of the GABA and SR95531 applications. In saturating (10 mm) GABA, the half-inhibitory concentrations of SR95531 (IC50) when coapplied with GABA to α1β1γ2S or α1β1 receptors were 49 and 210
Purpose of review This review addresses recently reported evidence for alternative cellular pathways for haematopoietic stem cell lineage commitment. Recent findings Using various approaches, several laboratories suggested the existence of adult as well as foetal multipotent progenitor cells with combined B cell, T cell and granulocyte/macrophage potential, but little or no megakaryocyte/erythroid
Anti-leukotriene therapy represents a new principle in asthma treatment. As elite athletes can have asthma, this double-blind, placebo-controlled, randomised cross-over study investigated the effect of 10 mg oral montelukast, a specific and potent cysteinyl leukotriene receptor antagonist, on physiological responses to submaximal and maximal aerobic exercise at -15 degrees C in 14 non-asthmatic hi
Rat models are useful for studies of the pathogenesis of rheumatoid arthritis (RA) since rats are extraordinarily sensitive to induction of arthritis with adjuvants. Injection of not only the classical complete Freund's adjuvant but also mineral oil without mycobacteria and pure adjuvants such as pristane and squalene, induce severe arthritis in many rat strains. Models like pristane-induced arthr
Popular Abstract in Swedish Under senare år har datorn kommit att bli ett vanligt inslag i förskolans dagliga verksamhet. Visioner och planer har formulerats, inte minst politiskt. Det har sedan varit upp till pedagogerna att organisera och genomföra datoranvändandet i den lokala förskolevardagen. Avhandlingens övergripande syfte är att studera datoranvändandets praktik i förskolan. Avsikten är däThe purpose of this thesis is to study the computer using practice within pre-school activity, or more specifically, to study aspects of meaning-making as afforded when the computer is in use in pre-school. In the study a socio-cultural perspective is used as the point of departure combined with an Ecological approach to visual perception and Positioning theory. Data was collected in three pre-sch
There are specific receptors for the active metabolite of vitamin D on the pancreatic beta cells and severe vitamin D deficiency can inhibit insulin secretion. In the present study 14 middle aged men with impaired glucose tolerance and low glucose-stimulated insulin values received 2 micrograms alphacalcidol daily for 18 months. On treatment there was a transient increase of both the peak and the
Sodium stearoyl-2 lactylate (SSL) lipid surfactant molecules specifically bind partially hydrolysed oat proteins in aqueous medium and significantly enhance the dispersion stability of oat cereal preparations. The proposed complexation is composition dependent and a greater understanding of the role of both oat proteins and lipid surfactant in the effect was gained with data from high performance
Physical activity has been suggested to be one of the determinants of bone turnover and to prevent age-related bone loss. To examine this we measured the serum levels of osteocalcin (bone Gla-protein, BGP), C-terminal procollagen peptide (PICP), serum alkaline phosphatase, bone-specific alkaline phosphatase, and S-calcium as indices of bone formation in 19 actively performing and 15 ex-lifters. Al
Three-dimensional numerical simulations with CO5, a newradiation hydrodynamics code, result in a dynamic, thermally bifurcatedmodel of the non-magnetic chromosphere of the quiet Sun. The 3D modelincludes the middle and low chromosphere, the photosphere, and the topof the convection zone, where acoustic waves are excited by convectivemotions. While the waves propagate upwards, they steep
