The UV-dissipative mechanisms of the eumelanin building block 5,6-dihydroxyindole-2-carboxylic acid (DHICA) and the 4,7-dideutero derivative (DHICA-d(2)) in buffered H(2)O or D(2)O have been characterized by using ultrafast time-resolved fluorescence spectroscopy. Excitation of the carboxylate anion form, the dominating state at neutral pH, leads to dual fluorescence. The band peaking at lambda=37
The electroenzymatic reactions of Trametes hirsuta laccase in the pure organic solvent dimethyl sulfoxide (DMSO) have been investigated within the framework for potential use as a catalytic reaction scheme for oxygen reduction. The bioelectrochemical characteristics of laccase were investigated in two different ways: (i) by studying the electroreduction of oxygen in anhydrous DMSO via a direct ele
The expression of genes specifically in B cells is of great interest in both experimental immunology as well as in future clinical gene therapy. We have constructed a novel enhanced B cell-specific promoter (Igk- E) consisting of an immunoglobulin kappa (Igk) minimal promoter combined with an intronic enhancer sequence and a 30 enhancer sequence from Ig genes. The Igk- E promoter was cloned into a
The aim of this study was to describe some of the factors that might play a role in influencing attitude to xenotransplantation: first, the consideration of receiving cells and tissue from xenotransplants in relation to whole xeno-organs; secondly, the fact that there is greater uncertainty regarding the result and risk of infection associated with xenotransplantation than with allotransplantation
The Na-33 beta decay was studied online using mass separation techniques and a first description of the level structure of the neutron-rich isotope Mg-33, with N=21, has been obtained. The experiment involved the measurement of beta-gamma, beta-gamma-gamma, and beta -n-gamma coincidences as well as neutron spectra by time-of-flight technique. The first low energy level scheme for the daughter nucl
Popular Abstract in Swedish Den dansk-svenske forfatter Gustaf Munch-Petersen (1912-1938) betragtes som en af portalskikkelserne i den danske lyriske modernisme. Han døde 26 år gammel som frivillig i den spanske borgerkrig, en konflikt, vi i dag ofte betragter som en del af optakten til anden verdenskrig. Dette tidlige endeligt gjorde ham til en af skandinavisk litteraturs ”unge døde”. Men det er
A succession of 26 conodont zones and 63 successive subzones and conodont faunas have been identified in the exposed latest Landovery to latest Ludlow strata of Gotland, Sweden. All zones, and several of the subzones and faunas, have been identified elsewhere on Baltica as well as on other palaeocontinents, indicating that this zonation serves well as the standard zonation for calcareous successio
The decreased survival of von Willebrand factor (VWF) in plasma has been implicated as a mechanism in a subset of type 1 von Willebrand disease (VWD) patients. We have previously reported that the ratio of plasma levels of VWF and its propeptide (VWFpp) can be used to identify patients with reduced VWF survival. In this study, we report the assay of VWFpp and VWF:Ag in 19 individuals recruited fro
Based on detailed 2D and 3D numerical radiation hydrodynamicscalculations of time-dependent compressible convection, we have studiedthe dynamics and thermal structure of the convective surface layers of aprototypical late-type M-dwarf at Teff=2800 K, and log g=5.0with solar chemical composition. The thermal structure of the atmosphereis dominated by molecular absorption, the formation o
The heavy recession in Sweden during the first half of the nineties led to a very difficult situation for young people with a weak position on the labour market. Around a third of the youths born in the mid seventies had received social welfare benefits before the age of 24. Despite the recovery in the Swedish economy a group of young adults, now in their thirties, simply can not find a way to eit
Objectives: To measure treatment fidelity and to evaluate patient and clinician experiences with Brief Admission Skåne (BAS) over the pilot phase and first five months of the intervention phase of a randomized controlled trial (RCT) testing BAS. The purpose of the RCT is to determine whether BAS can reduce the frequency of acute psychiatric admissions for individuals with borderline personality di
Certain types of implanted medical devices depend on oxygen supplied from surrounding tissues for their function. However, there is a concern that the tissue associated with the foreign body response to implants may become impermeable to oxygen over the long term and render the implant nonfunctional. We report oxygen flux recordings from electrochemical oxygen sensor devices with wireless telemetr
Cytogenetic studies over the past few decades have revealed clonal chromosomal aberrations in almost 27,000 human neoplasms. Many of these neoplasia-associated chromosomal abnormalities have been characterised at the molecular level, revealing previously unknown genes that are closely associated with the tumorigenic process. Information on chromosome changes in neoplasia is growing rapidly, making
Under 1970-talet genomfördes en rad förändringar i lagar och avtal som berörde arbetsmiljöns område. Ett arbetsmiljöavtal slöts mellan LO, SAF och PTK 1976. Skyddsombudens ställning stärktes 1973 genom förändringar i arbetarskyddslagen, och under 1978 infördes en helt ny arbetsmiljölag med ett vidgat arbetsmiljöbegrepp som även inkluderade den psykosociala arbetsmiljön. Året dessförinnan kom en ny
That a load balancing strategy using stale information care lessly will incur system performance degradation is easy to verify. However it is not so obvious that routing a customer to the expected shortest queue has the same problem when information for decision is stale. We consider a queueing system with a load balancer and a pool of identical FCFS queues in parallel. The arrival process is assu
A novel platinum complex with 1,3-bis(2,6-diisopropylphenyl)-1,3-dihydro-2H-imidazol-2-ylidenyl ligand has been synthesized and characterized on the basis of elemental analysis, MS, 1H and 13C NMR spectroscopy, X-ray Absorption Spectroscopy and single crystal X-ray diffraction studies. The XRD determination of the complex (monoclinic, C2/c) revealed a structure in which the platinum (II) centre co
The purpose of the present study is to try an alternative way of analyzing the ABR (Auditory Brainstem Response). The stimuli were complex sounds (c-ABR) as used in earlier studies. It was further aimed at corroborating earlier findings that this method can discriminate several neuropsychiatric states. Forty healthy control subjects, 26 subjects with the diagnosis schizophrenia (Sz) and 33 with AD
The performance of 2.7 mu m superficially porous particles at 600 bar and sub-2 mu m fully porous particles at 1000 bar were compared by the Poppe plot method. Theoretical Poppe plots were first constructed for each stationary phase to compare their kinetic performance at different analysis times. The theory was then verified by experiments under the optimized conditions identified from the Poppe
