Objective-In clinical islet transplantation, the instant blood-mediated inflammatory reaction (IBMIR) is a major factor contributing to the poor initial engraftment of the islets. This reaction is triggered by tissue factor and monocyte chemoattractant protein (MCP)-1, expressed by the transplanted pancreatic islets when the islets come in contact with blood in the portal vein. All currently ident
This paper argues that there is a norm in the publication of quantitative management research that accepted hypotheses are conceived of as good hypotheses. This has far-reaching implications for quantitative research in that, in the worst case scenario, this norm encourages commonsensical research questions and manipulation of data in order for an article to be published. Naturally, such behavior
Temporal compressions of optical pulses and pulse trains have been performed by the photon-echo process in Tm-doped YAG at 793 nm. Single-pulse temporal compression by almost a. factor of 500 from 10 mu s to 22 ns and pulse train compression by a factor of 14 from 5 mu s to 350 ns with a high-speed frequency-tunable external-cavity diode laser are demonstrated. It is suspected that significantly h
The effects of two different prevention programmes on: (1) reported neck, shoulder and back pain, (2) perceived physical exertion at work and perceived work-related psychosocial factors, were evaluated by questionnaires after 12 and 18 months. Female nursing aides and assistant nurses (n = 282) working in the home-care services, were randomly assigned to one of three groups for: (1) individually d
In aqueous solutions hydrophobically modified polyethylene glycol (HM-PEG) forms a transient polymer network held together by intermolecular hydrophobic associations. In the present investigation we have used NMR-diffusometry to study how the addition of methylated alpha-cyclodextrin (M-alpha-CD) influences the polymer network. The addit on of M-alpha-CD resulted in an increased mean self-diffusio
The mol-ecule of the title compound, C14H14S, lies on a crystallographic twofold axis running through the central S atom, and hence mol-ecules have exact C-2 mol-ecular symmetry. Density-functional theory calculations reveal that the energy-optimized mol-ecular structure in the gas phase is close to that observed in the crystal structure. The crystal packing is dominated by double chains running a
Popular Abstract in Swedish Det har traditionellt sett varit mycket svårt att genomföra förbränningsstudier i motorer, men i och med laserns introduktion har nya möjligheter öppnats. Under de senaste 20 åren har lasern blivit ett allt viktigare hjälpmedel, och ett stort antal laser baserade mätmetoder har utvecklats. Det är nu möjligt att mäta temperaturer, ämneskoncentrationer, hastighetsfält ochMulti-dimensional, laser-based measurements of quantities important for obtaining a better understanding of combustion processes, particularly of temperature and of species distributions, were performed using laser-induced fluorescence (LIF). The main purpose of the temperature experiments was to investigate the potential of employing a two-line atomic fluorescence technique (TLAF), using indium a
Earlier light microscopic, immunocytochemical and morphometric investigations indicate that noxious substances transported with the vasogenic edema from hemispheric infarcts influence the character, timing and extent of the secondary thalamic lesions. The object of the present study was to analyze the ultrastructure of the secondary damage and the cytolytic nerve cell change which ensues in the th
BACKGROUND: Hereditary non-polyposis colorectal cancer (HNPCC) (Lynch cancer family syndrome I (LCFS1) and II (LCFS2)) is one of the most common hereditary cancer disorders. HNPCC results from dominantly inherited germline mutations in mismatch repair (MMR) genes, leading to genomic instability and cancer. No predictive physical signs of HNPCC are available to date. AIMS: Increased complexity in t
Popular Abstract in Swedish De flesta primärar hjärntumörer utgår ifrån astrocyter, oligodendrocyter och ependymala celler, som är hjärnvävnadens egna celler. Cirka hälften av dessa tumörer ingår i en grupp där tumörtypen heter gliom. Glioblastoma multiforme (GBM) är den mest elakartade tumören inom denna grupp och också den vanligast förekommande.Trots stora forskningssatsningar är behandlingsstrGlioblastoma multiforme (GBM) is the most malignant and also the most common form of brain tumour in humans. The overall aim of this thesis was to investigate morphological and diagnostics features in human GBM that may be of importance for prognosis and treatment. Immunohistochemically stained tissue sections have been microscopically analysed regarding immuno-reactive cells, cell proliferation,
Background: Loss of chromosome 11q defines a subset of high-stage aggressive neuroblastomas. Deletions are typically large and mapping efforts have thus far not lead to a well defined consensus region, which hampers the identification of positional candidate tumour suppressor genes. In a previous study, functional evidence for a neuroblastoma suppressor gene on chromosome 11 was obtained through m
A theoretical model has been developed for the drop behaviour in siphon riser tubes in paper drying cylinders. Analytical solutions to the equations are presented for the systems air-water at atmospheric pressure and saturated steam-water. Numerical simulations are performed for a large number of input data. Calculated drop trajectories indicate that the drops travel only a small part of the riser
A group of chest physicians, general practitioners, clinical pharmacologist and pharmacists appointed by the Institute of Pharmacotherapy, University of Oslo has evaluated the present knowledge about treatment of chronic obstructive lung disease. The group discusses today's medical treatment of this rather numerous group of patients. It is stated that, to a high degree, the treatment of these pati
Severely deficient activity of the von Willebrand Factor (VWF) cleaving metalloprotease,ADAMTS 13, is associated with thrombotic thrombocytopenic purpura (TTP). The mutation spectrum ofADAMTS 13 is rather heterogeneous, and numerous mutations spread across the gene have been described in association with congenital TTP. The 4143insA mutation is unusual with respect to its geographic concentration.
