The reduction of a thin surface oxide on the Rh(1 1 1) surface by CO is studied in situ by photoemission spectroscopy, scanning tunneling microscopy, and density functional theory. CO molecules are found not to adsorb on the surface oxide at a sample temperature of 100 K, in contrast to on the clean and chemisorbed oxygen covered surface. Despite this behavior, the surface oxide may still be reduc
Context: Inflammation and adipogenesis are two parallel processes with increased activity in severe Graves' ophthalmopathy. Objective: The aim of this work was to define target genes for therapeutic intervention in adipogenesis and inflammation in Graves' ophthalmopathy. Design: Orbital tissue was obtained from patients with ophthalmopathy in acute or chronic phase undergoing orbital surgery to st
BACKGROUND: Effective T-cell depletion is a prerequisite for haploidentical peripheral blood progenitor cell (PBPC) transplantation. This study was performed to investigate the performance of magnetic cell sorting–based direct large-scale T-cell depletion, which is an attractive alternative to standard PBPC enrichment procedures. STUDY DESIGN AND METHODS: PBPCs were harvested from 11 human leukoc
During a Swedish-Russian expedition to northern Siberia 1994, we sampled two marginal populations of two Carex species at two high arctic sites (C. stuns Drej. on Faddeyevsky Island and C. ensifolia V. Krecz ssp, arctisibirica Jurtz. at north-eastern Taymyr Peninsula), both north of previously documented localities in that areas for the two species. These populations were composed of a few distinc
A combined sample preparation and sample presentation device, Integrated Selective Enrichment Target (ISET), consisting of an array with 96 perforated nanovials is described. Each perforated nanovial can be filled with soild-phase extraction media for purification and concentration of biomolecules prior to mass spectrometry. The ISET platform provides an efficient, economic and generic sample trea
Brain hypothermia is at present the most effective neuroprotective treatment against brain ischemia in man. Ischemia induces a redistribution of proteins involved in synaptic functions, which is markedly diminished by therapeutic hypothermia (33 degrees C). Dendritic spines at excitatory synapses are motile and show both shape changes and rearrangement of synaptic proteins as a consequence of neur
The consumption of alcohol imposes costs on the society and several cost-of-illness studies have been conducted to estimate these costs. This essay presents the results from five cost-of-illness studies and examines the methodology used. The differences in results are discussed in reference to the differences in the applied methods. The results differ immensely from US$ 91 to US$ 2,433 per capita.
Molecularly imprinted polymers (MIPs) are being increasingly used as selective adsorbents in different analytical applications. To satisfy the different application purposes, MEN with well controlled physical forms in different size ranges are highly desirable. For examples, MIP nanoparticles are very suitable to be used to develop binding assays and for microfluidic separations, whereas MIP beads
Grounded theory (GT) is a popular research method for exploring human behavior. GT was developed by the medical sociologists Glaser and Strauss while they studied dying in hospitals in the 1960s resulting in the book "Awareness of dying". The goal of a GT is to generate conceptual theories by using all types of data but without applying existing theories and hypotheses. GT procedures are mostly in
In order to study the plasma levels of factor XaI and IIaI activity an enzymatically depolymerized low molecular weight heparin (LMW-heparin; Logiparin) was given s.c. in a dose of 35 XaI mu/kg b.w. once daily for 7 days to 10 patients undergoing total hip replacement (THR) in a pilot study. The XaI activity was less than or equal to 0.24 XaI units/ml and the IIaI activity less than or equal to 0.
The structure, luminescence spectroscopy, and lifetime decay dynamics of Eu2O3 nanoparticles formed in MCM-41 have been investigated. Both X-ray diffraction and high-resolution transmission electron microscopic observations indicate that Eu2O3 nanoparticles of monoclinic structure are formed inside channels of MCM-41 by heating at 140 degreesC. However, heat treatment at 600 or 700 degreesC causes
Recombinant factor VIIa (rFVIIa) has been developed for treatment of bleeding in patients with hemophilia who have inhibitors against factor VIII (FVIII) or FIX, and has been found to induce hemostasis during major orthopedic surgery. The use of rFVIIa treatment for hemophilia is a new concept and is based on the low-affinity binding of FVIIa to the surface of thrombin-activated platelets. Adminis
Popular Abstract in Swedish Metoder behövs att noggrant mäta rörelse och slitage av ledpannan efter operation med konstgjord höftled. EBRA-metoden (Ein Bild Röntgen Analyse) presenterades nyligen som en datoriserad metod att mäta rörelse av ledpannan. I denna studie utvärderades ett antal standardmetoder att mäta rörelse av ledpannan och jämfördes med radiostereometri (RSA), en metod som visats haMethods are needed for accurate measurement of acetabular cup migration and wear after hip replacement. The EBRA (Ein Bild Röntgen Analyse) method was recently introduced as a computerized method for radiographic assessment of acetabular cup migration. In this study, various standard methods for measuring migration were evaluated and compared to radiostereometry (RSA), which has proved to be high
