IL-3 and IL-4 activate cyclic nucleotide phosphodiesterases 3 (PDE3) and 4 (PDE4) by different mechanisms in FDCP2 myeloid cells

In FDCP2 myeloid cells, IL-4 activated cyclic nucleotide phosphodiesterases PDE3 and PDE4, whereas IL-3, granulocyte-macrophage CSF (GM-CSF), and phorbol ester (PMA) selectively activated PDE4. IL-4 (not IL-3 or GM-CSF) induced tyrosine phosphorylation of insulin-receptor substrate-2 (IRS-2) and its association with phosphatidylinositol 3-kinase (PI3-K). TNF-alpha, AG-490 (Janus kinase inhibitor),

A PIXE System for Routine Longitudinal Scanning of Single Hair Strands

This article describes a PIXE system designed and constructed for routine longitudinal scanning of single hair strands. In constructing a PIXE system for trace elemental scans of single hair strands on a routine basis, a fairly intense beam has to be used but the heating damage must be kept to a minimum. The experimental conditions (charge integration, beam homogeneity etc.) have to be carefully c

Billigare, effektivare och mer kompetent genom samarbete

Hur ska den svenska samhällsstrukturen vara utformad? Vem ska egentligen göra vad? Detta är centrala frågor som idag diskuteras flitigt när man både på nationell och lokal nivå konstaterar att det är gott om framtida utmaningar. Delvis råder det nu en situation där 'hela havet stormar' när den befintliga samhällsstrukturen är under utredning genom t ex Ansvarskommittén. Inom avfallsområdet har eme

Xenoestrogenic activity in blood of European and Inuit populations

BACKGROUND: Human exposure to persistent organic pollutants (POPs) is ubiquitous and found in all individuals. Studies have documented endocrine disrupting effects and impact on reproduction. The aim of the present study was to compare the level of xenoestrogenic activity in serum of groups with varying POP exposure, and to evaluate correlations to the POP biomarkers, 2,2',4,4',5,5'-hexachlorobiph

Mobile Positioning in MIMO System Using Particle Filtering

Abstract—This paper represents the results of a simulation study on positioning of a mobile unit in MIMO settings. We used two different approaches for modeling the mobile movement, combined with a simple geometrical model for the MIMO channel. Three different particle filters were implemented for the position estimation. The results show that all three filters are able to achieve estimation accur

Reproductive isolation in temperate reef fishes

pportunity and recognition isolation can lead directly to reproductive isolation, the former via divergence in the location and timing of breeding, and the latter via differential mate preferences. We describe the potential significance of these factors in the maintenance of reproductive isolation in a clade of triplefin fishes that occur sympatrically around coastal New Zealand. Specifically, we

Kriging with Nonparametric Variance Function Estimation

A method for fitting regression models to data that exhibit spatial correlation and heteroskedasticity is proposed. It is well known that ignoring a nonconstant variance does not bias least-squares estimates of regression parameters; thus, data analysts are easily lead to the false belief that moderate heteroskedasticity can generally be ignored. Unfortunately, ignoring nonconstant variance when f

Spela snyggt och ha kul : Gemenskap, sammanhållning och musikalisk utveckling i en amatörorkester

In a Swedish brass band a program for change was pursued which aimed to improve the artistic level of playing of the ensemble without replacing less competent members. At the time for the study the band comprised 34 members, four of whom were female. The research question was: How does community and group coherence interact with the goal to improve the musical standard in an amateur brass band? T

Ocular and scleral alterations in gene-targeted lumican-fibromodulin double-null mice.

PURPOSE: To elucidate the role of leucine-rich proteoglycans lumican and fibromodulin in the sclera. METHODS: Lumican- and fibromodulin-null heterozygous mice were intercrossed to obtain wild-type (Lum(+/+)Fmod(+/+)), lumican-null (Lum(-/-)Fmod(+/+)), fibromodulin-null (Lum(+/+)Fmod(-/-)), and double-null (Lum(-/-)Fmod(-/-)) littermates. Axial length was measured on enucleated whole eyes, and ocul

Soft Tissue Sarcoma Patterns multiplicity, heterogeneity and growth characteristics

Soft tissue sarcomas (STS) represent a group of rare and heterogenous tumors that optimally should be diagnosed and treated within multidisciplinary teams. This thesis has studied various aspects ? pathological, genetical, and clinical ? of STS. In study I, we demonstrated that 20% of the patients in a population-based series of 818 STS developed second primary malignancies. An increased risk of

Hydroxy-PCBs, PBDEs, and HBCDDs in serum from an elderly population of Swedish fishermen's wives and associations with bone density

Lack of human exposure data is frequently reported as a critical gap in risk assessments of environmental pollutants, especially regarding "new" pollutants. The objectives of this study were to assess serum levels of the persistent 2,2',4,4',5,5'-hexachlorobiphenyl (CB-153), hydroxylated polychlorinated biphenyl metabolites (OH-PCBs), polybrominated diphenyl ethers (PBDEs), and hexabromocyclododec

Särskolebarn i integrerad skolbarnsomsorg

Popular Abstract in Swedish Huvudtanken i svensk välfärdspolitik är att genom generella åtgärder skapa ett samhälle tillgängligt för alla medborgare. Det är därför viktigt att undvika segregering och särlösningar och i stället höja normalverksamhetens standard. Fritidshemmets mål och uppgifter är desamma för alla barn och kvaliteten i verksamheten ska vara så hög att alla barns behov tillgodoses. The main idea behind the Swedish welfare state is to create a society accessible to all citizens by using to general measures. It is, therefore, important to avoid segregation and special solutions, and instead increase the standard of normal activities. The objectives and tasks of day centres for school-age children are the same for all children and the quality of the operations should be of a st

Method for analysis of methyltetrahydrophthalic acid in urine using gas chromatography and selected ion monitoring

A method for the determination of methyltetrahydrophthalic acid (MTHP acid), a metabolite of methyltetrahydrophthalic anhydride (MTHPA) in human urine, was developed. The investigated MTHP acid was obtained by hydrolysis of a commercial MTHPA mixture, composed of three major isomers. These were synthesized and identified as 3-methyl-delta 4-tetrahydrophthalic anhydride, 4-methyl-delta 4-tetrahydro

Harvesting spatially distributed populations

Spatial structure has a paramount influence on population dynamics. This has until recently been neglected in harvesting theory. In this paper, we demonstrate how source-sink and habitat selection theory can provide guidance for harvesting spatially structured populations. We also show how harvesting can affect the spatial distribution of the exploited resource, which has consequences for the desi

Home care with regard to definition, care recipients, content and outcome: systematic literature review.

In spite of the fact that home care has grown considerably during the last few years and will continue to grow even more in the future, home care as a phenomenon and a concept is not clearly defined. The aim of this study was to review the empirical literature for the description of home care as a phenomenon and as a concept, especially with regard to who the care recipients are, what actions and
