    • A Book Exchange Across BordersAndreas Kallström as an Agent for the Bergius Brothers in the 1760sThe article tells about a book exchange in 1765 between Peter Jonas and Bengt Bergius and an anonymous English gentleman through the help of Andreas Kallström, a Swedish student of botany and horticulture, during his stay in London 1764-1765 as a part of his studies. The correspondence between the Bergius brothers and Kallström shows that the exchange was unprofessionally handled and troublesome for Kallström. However, he manages to get the books that the brothers Bergius wished for before leaving London for Paris. The correspondence gives us also clues on the importance of the bookbindings, as well as other material aspects of the book, as part of the commerce with books during the later eighteenth century. Different aspects on the exchange of books across the Swedish borders give us a fuller picture of the commerce at the time.

  • Great differences in performance and outcome of high-throughput sequencing data analysis platforms for fungal metabarcoding
  • 2018
  • In: MycoKeys. - : Pensoft Publishers. - 1314-4057 .- 1314-4049. ; 39, s. 29-40
  • Journal article (peer-reviewed)abstract
    • Along with recent developments in high-throughput sequencing (HTS) technologies and thus fast accumulation of HTS data, there has been a growing need and interest for developing tools for HTS data processing and communication. In particular, a number of bioinformatics tools have been designed for analysing metabarcoding data, each with specific features, assumptions and outputs. To evaluate the potential effect of the application of different bioinformatics workflow on the results, we compared the performance of different analysis platforms on two contrasting high-throughput sequencing data sets. Our analysis revealed that the computation time, quality of error filtering and hence output of specific bioinformatics process largely depends on the platform used. Our results show that none of the bioinformatics workflows appears to perfectly filter out the accumulated errors and generate Operational Taxonomic Units, although PipeCraft, LotuS and PIPITS perform better than QIIME2 and Galaxy for the tested fungal amplicon dataset. We conclude that the output of each platform requires manual validation of the OTUs by examining the taxonomy assignment values.

  • Contribution to the coordination chemistry of transition metal nitroprussides : a cryo-XPS study
  • 2019
  • In: New Journal of Chemistry. - : Royal Society of Chemistry. - 1144-0546 .- 1369-9261. ; 43:12, s. 4835-4848
  • Journal article (peer-reviewed)abstract
    • The series of coordination polymers under investigation was formed by the assembly of a pentacyanonitrosylferrate(ii) anionic block, [Fe(CN)(5)NO](2-), through monovalent and divalent transition metal ions, e.g. Mn2+, Fe2+, Co2+, Ni2+, Cu2+, Zn2+, Cd2+, Hg2+ and Ag+. For divalent ions, the resulting materials have a 3D porous framework with attractive features for applications in gas storage and separation, as electroactive solids, light-driven molecular magnets, and so on; in this study, we report the results obtained for a series of coordination polymers using the cryogenic X-ray photoelectron spectroscopy (cryo-XPS) data; comprehensive details regarding their coordination chemistries were obtained from the acquired spectra in addition to their comparison with the structural and spectroscopic information obtained from other techniques. The results discussed herein are original and contribute towards the understanding of the electronic structures and related properties for this family of coordination polymers. This series of solids was found to be highly susceptible to strong damage induced by X-ray beams throughout the conventional XPS experiment; therefore, the analysis was conducted under cryogenic conditions.

  • An Extended Transition Energy Cost Model for Buses in Deep Submicron Technologies
  • 2004
  • In: Proceedings of the Power and Timing Modeling, Optimization and Simulation Conference, Santorini, Greece. - Berlin, Heidelberg : Springer Berlin/Heidelberg. - 9783540230953 - 9783540302056 ; , s. 849-858
  • Conference paper (peer-reviewed)abstract
    • In this paper we present and carefully analyze a transition energy cost model aimed for efficient power estimation of performance critical deep submicron buses. We derive an accurate transition energy cost matrix, scalable to buses of arbitrary bit width, which includes properties that closer capture effects present in high-performance VLSI buses. The proposed energy model is verified against Spectre simulations of an implementable bus, including drivers. The average discrepancy between results from Spectre and the suggested model is limited to 4.5% when fringing effects of edge wires is neglected. The proposed energy model can account for effects that limit potential energy savings from bus transition coding.

  • Long-term addition of compost and NP fertilizer increases crop yield and improves soil quality in experiments on smallholder farms
  • 2014
  • In: Agriculture, Ecosystems and Environment. - : Elsevier BV. - 0167-8809 .- 1873-2305. ; 195, s. 193-201
  • Journal article (peer-reviewed)abstract
    • Soil fertility decline due to low nutrient input is a constraint for sustainable agriculture in smallholder farming systems in Ethiopia. In this study, crop productivity and soil organic matter buildup were compared in soils receiving locally made compost, applied either alone or in combination with NP fertilizer. The experiments had four treatments: full dose of compost (C), full dose of fertilizer (F), half compost and half fertilizer (CF), and unfertilized control (control). The full dose of compost was equivalent to 2.4 t ha(-1) organic matter. The field study was conducted on four farm fields in the village Beseku, each representing different sub-villages. Participating farmers were selected based on their willingness and an assessment of dedication to carry out the experiment. The experiments, a randomized complete block design with three replications, were replicated across four farm fields. The treatments were repeated for six cropping seasons (years), and data on soil nutrient status and crop (maize, wheat, potato, and faba bean) harvests were collected. In the 0-10 cm soil layer, pH was (P < 0.05) lower in the F treatments than in the C and CF treatments. Compared with the F treatment, the soil organic carbon (SOC) and total nitrogen stocks increased (P < 0.05) by 4.60 and 0.42 t ha(-1) in C treatment, and by 4.74 and 0.45 t ha(-1) in CF treatment. Treatment effects on crop harvests were significant (P < 0.05) for all crops grown across the sites and seasons. The highest maize yield was obtained from CF, with relative harvest of 178% compared with the control and 126% compared with F, but was comparable to C. For wheat and potato, the yields obtained from CF, C and F were comparable. For faba bean, CF had a relative harvest of 145% over the control. Maize harvest was in the order of CF > F> C> control in the initial season, CF > C> F> control in the next three consecutive seasons, and C> CF> F> control in the final year of the experiment. The overall combined yield was in the order of CF > C> F> control for maize and faba bean, CF > F> C> control for potato, and F> CF > C> control for wheat. The addition of either compost alone or in combination with NP fertilizer improved soil properties and crop productivity, compared with control and only fertilizer addition. Therefore, compost addition can serve as a complement to fertilizer use and reduce dependence on mineral fertilizer in low-input crop production system. The apparent synergy between compost and fertilizer addition needs further research in order to be explained. (C) 2014 Elsevier B.V. All rights reserved.

  • Structures and stabilities of mixed clusters of fullerene and coronene molecules
  • Other publication (other academic/artistic)abstract
    • We have performed molecular dynamics simulations on the formation of mixed molecular clusters of buckminster- fullerene and coronene, (C24H12)n(C60)N−n. We report on our findings on the structures and their relative stabilities for cluster sizes N = 5 and 13 and for all possible combinations of the two species within these sizes, including the pure clusters of each type. Generally, we see that the two species mix rather poorly and that compactly bound clusters are favoured over spatially extended ones. For a given ratio of coronene and fullerene, clusters with one or two coronene stacks tend to be more stable than those with a larger number of stacks. In the case of small clusters, the coronene and fullerene molecules tend to separate into two different cluster parts. For larger clusters, this is often but not always the case.

  • (Re)constructing economic citizenship in a welfare state – intersections of gender and class
  • 2013
  • In: Equality, Diversity and Inclusion: An International Journal. - 2040-7149. ; 33:2, s. 122-139
  • Journal article (peer-reviewed)abstract
    • Purpose – The purpose of the paper is to discuss and illustrate how contemporary market discourses rearticulate socio-political relationships and identities, including the rights, duties, and opportunities of individuals and categories of individuals as citizens. More specifically, the purpose is to analyze how “economic citizenship” is articulated and negotiated in the intersection of (Nordic) welfare state ideals and shareholder-oriented market discourses. The paper further elaborates on how different identity markers, especially gender and class, intersect in these articulations and contribute to exclusionary practices. Design/methodology/approach – The paper approaches the articulation of economic citizenship through an empirical study that focusses on business media representations and online discussions of a major factory shutdown in Finland. Drawing from discourse theory and the notions of representational intersectionality and translocational positionality, the paper analyzes how gender and class intersect in the construction of economic citizenship in the business media. Findings – The study illustrates how financialist market discourses render citizenship intelligible in exceedingly economic terms, overriding social and political dimensions of citizenship. The business media construct hierarchies of economic citizens where two categories of actors claim full economic citizenship: the transnational corporation and the transnational investor. Within these categories, particular systems of privilege intersect in similar ways, rendering them masculine and upper middleclass. Whether interpreted as hegemonic or counter-hegemonic, the financialist discourses rearticulate the social hierarchies and moral landscape in Finnish society. Originality/value – The paper contributes to critical/feminist management studies by elaborating on the role of the business media as an important site of political identity work, positioning, and moral regulation, where neoliberal ideas, based upon and reproducing masculine and elitist systems of privilege, appear as normalized and self-evidently valued.

  • Can modernization generate productive aging? : Some Swedish experiences
  • 2011
  • In: Productive Engagement in Later Life. - Beijing : China Society Press. - 9787508736112 ; , s. 107-122
  • Book chapter (other academic/artistic)abstract
    • The chapter deals with the question how old pensions and care work for old people have been discussed earlier and at presnt in Sweden. The chapeter starts with a brief overview if the Swedish welfare model, focussed on two distinct periods: the 1950s - 1960s with a rapid econmic growth and the present period of economic decline. After a long expansion period of a tax - financed public sector under the name of "productive welfare strategy", calculations indicated a state economy in imbalance. Resources did not increase at the same pace as the numbers of elderly. An organizationnal reconstruction of the public sector started with market solutions, encouragement of an increase in voluntary work and family based care. A new pensions system was introduced in the 1990s, and higher expectations of quality at a lower cost turned questions of staff teaining and qualifications to highly strategical themes. A new anti-discrimination Act came into force in 2009. The chapter is finalized by a presentation of some of the research performed within the research profile Care Work and Social Gerontology at the Department of Social Work at Umea University. Issues like social capital and care work, old womens life stories, family obligations in transition, attitudes to old people including ageism as well as training for care workers are issues researched within the team.

  • Accumulation and activation of natural killer cells in local intraperitoneal HIV-1/MuLV infection results in early control of virus infected cells
  • 2011
  • In: Cellular Immunology. - : Elsevier BV. - 0008-8749 .- 1090-2163. ; 272:1, s. 71-78
  • Journal article (peer-reviewed)abstract
    • Natural killer (NK) cells are important effectors in resistance to viral infections. The role of NK cells in the acute response to human immunodeficiency virus 1 (HIV-1) infected cells was investigated in a mouse model based on a HIV-1/murine leukemia virus (MuLV) pseudovirus. Splenocytes infected with HIV-1/MuLV were injected intraperitoneally and local immunologic responses and persistence of infected cells were investigated. In vivo depletion with an anti-NK1.1 antibody showed that NK cells are important in resistance to virus infected cells. Moreover, NK cell frequency in the peritoneal cavity increased in response to infected cells and these NK cells had a more mature phenotype, as determined by CD27 and Mac-1 expression. Interestingly, after injection of HIV-1/MuLV infected cells, but not MuLV infected cells, peritoneal NK cells had an increased cytotoxic activity.

  • Short-Term Exercise Training Does Not Stimulate Skeletal Muscle ATP Synthesis in Relatives of Humans With Type 2 Diabetes
  • 2009
  • In: Diabetes. - : American Diabetes Association. - 1939-327X .- 0012-1797. ; 58:6, s. 1333-1341
  • Journal article (peer-reviewed)abstract
    • OBJECTIVE-We tested the hypothesis that short-term exercise training improves hereditary insulin resistance by stimulating ATP synthesis and investigated associations With gene polymorphisms. RESEARCH DESIGN AND METHODS-We studied 24 nono-bese first-degree relatives of type 2 diabetic patients and 12 control subjects at rest, and 48 h after three bouts of exercise. In addition to measurements of oxygen uptake and insulin sensitivity (oral glucose tolerance test), ectopic lipids and mitochondrial ATP synthesis were assessed using H-1 and P-31 magnetic resonance spectroscopy, respectively. They were genotyped for polymorphisms in genes regulating mitochondrial function, PPARGC1A (rs8192678) and NDUFB6 (rs540467). RESULTS-Relatives had slightly lower (P = 0.012) insulin sensitivity than control subjects. In control subjects, ATP synthase flux rose by 18% (P = 0.0001), being 23% higher (P = 0.002) than that in relatives after exercise training. Relatives responding to exercise training with increased ATP synthesis (+19%, P = 0.009) showed improved insulin sensitivity (P = 0.009) compared with those whose insulin sensitivity did not improve. A polymorphism in the NDUFB6 gene from respiratory chain complex I related to ATP synthesis (P = 0.02) and insulin Sensitivity response to exercise training (P = 0.05). ATP synthase flux correlated with O-2 uptake and insulin sensitivity. CONCLUSIONS-The ability of short-term exercise to stimulate ATP production distinguished individuals with improved insulin sensitivity from those whose insulin sensitivity did not improve. lit addition, the NDUFB6 gene polymorphism appeared to modulate this adaptation. This finding suggests that genes involved in mitochondrial function contribute to the response of ATP synthesis to exercise training. Diabetes 58:1333-1341, 2009

  • The effect of calcium ion concentration on the bone response to oxidized titanium implants
  • 2012
  • In: Clinical Oral Implants Research. - Malden, USA : Wiley-Blackwell. - 0905-7161 .- 1600-0501. ; 23:6, s. 690-697
  • Journal article (peer-reviewed)abstract
    • Aim: To investigate the effect of calcium concentration on the bone tissue response to Ca-incorporated titanium implants.Materials and methods: Two titanium surfaces containing 4.2% and 6.6% calcium were prepared using the micro-arc oxidation process. The implants were inserted in the tibia of nine New Zealand White rabbits. After 6 weeks of healing, the bone response to the implants was quantitatively compared by biomechanical and histomorphometrical measurements.Results: Ca 4.2% and Ca 6.6% containing implants revealed no distinctive differences in their qualitative surface chemistry; chemical bonding state of Ca in titanium oxide was mainly calcium titanates. No significant differences were observed between two implants in peak removal torque and shear strength comparisons (P>0.05). Histomorphometrical analyses presented no significant differences in bonemetal contact, bone area and newly formed bone measurements between two implants (P>0.05).Conclusions: From biomechanical and histomorphometrical measurements, the two calcium concentrations in this study did not differ significantly with respect to their influence on the bone tissue response. This similar bone response in rabbit tibiae may be explained by the similarity of the qualitative Ca chemistry in titanium surfaces.

  • The future of asthma research and development : a roadmap from the European Asthma Research and Innovation Partnership (EARIP)
  • 2017
  • In: European Respiratory Journal. - : EUROPEAN RESPIRATORY SOC JOURNALS LTD. - 0903-1936 .- 1399-3003. ; 49:5
  • Journal article (peer-reviewed)abstract
    • A coordinated European multi-stakeholder approach to asthma research Asthma is highly prevalent and associated with high morbidity and mortality. It affects 30-50 million people in Europe, often starting in infancy and persisting throughout life. Asthma is a major global health challenge, affecting more than 300 million people worldwide and at least 10% of all Europeans [1]. People with asthma live at risk of life-threatening asthma attacks, leading to over 500 000 hospitalisations each year. Approximately 5-10% of asthma cases are so severe that current treatments do not work. The Framework Programme 7-funded European Asthma Research and Innovation Partnership (EARIP; www.EARIP.eu) was established in 2013 to harmonise efforts to reduce mortality and morbidity from asthma by agreeing the most important research priorities across relevant stakeholders in Europe. This is essential to address the significant impact of asthma on the individual, healthcare systems and national and European economies, outlined in the accompanying editorial in this issue of the European Respiratory Journal [2]. EARIP produced an evidence- and consensus-based list of the research priorities (a "roadmap") and investment needed to reduce asthma deaths and hospitalisations. By identifying the priorities, a coordinated effort can be made to fast-track change to better manage, prevent and cure asthma [3]. The roadmap will be the foundation on which future EU, national and international research funding programmes can transform asthma outcomes throughout Europe. The roadmap is the product of a comprehensive multi-stage process, led by the European Lung Foundation and Asthma UK (figure 1) [4]. Multiple stakeholder groups informed the roadmap process to ensure scientific accuracy, clinical relevance and outcomes that reflect the priorities of patients and caregivers, with an overarching steering board. A final consensus workshop brought together 28 experts from 15 European countries comprising: patients, patient organisations, primary healthcare professionals (HCPs), secondary HCPs, researchers, industry representatives and policy influencers. A full list of the roadmap contributors is available at www.EARIP.eu/roadmap. The rest of this article describes its development and outcomes.

  • Ultra-High-Throughput Clinical Proteomics Reveals Classifiers of COVID-19 Infection
  • 2020
  • In: Cell Systems. - : Elsevier BV. - 2405-4712 .- 2405-4720. ; 11:1, s. 11-24.E4
  • Journal article (peer-reviewed)abstract
    • The COVID-19 pandemic is an unprecedented global challenge, and point-of-care diagnostic classifiers are urgently required. Here, we present a platform for ultra-high-throughput serum and plasma proteomics that builds on ISO13485 standardization to facilitate simple implementation in regulated clinical laboratories. Our low-cost workflow handles up to 180 samples per day, enables high precision quantification, and reduces batch effects for large-scale and longitudinal studies. We use our platform on samples collected from a cohort of early hospitalized cases of the SARS-CoV-2 pandemic and identify 27 potential biomarkers that are differentially expressed depending on the WHO severity grade of COVID-19. They include complement factors, the coagulation system, inflammation modulators, and pro-inflammatory factors upstream and downstream of interleukin 6. All protocols and software for implementing our approach are freely available. In total, this work supports the development of routine proteomic assays to aid clinical decision making and generate hypotheses about potential COVID-19 therapeutic targets.

  • Journal article (peer-reviewed)abstract
    • The purpose of the paper is to analyze how participatory democracyhas been implemented in French communes. The question of neighbourhooddemocracy is a norm of political speech as local representatives need to legitimizetheir role in the public space by getting closer to their electors. Does theimplementation of participatory tools depend on the ideology and the socializationof the mayors or on the structure of the commune (size, territorial configuration)?The paper mainly uses a quantitative investigation made on communes above 5000inhabitants as well as interviews conducted in specific communes known for theirparticipatory culture.

  • Λ/K0s Associated with a Jet in Central Pb–Pb Collisions at √sNN = 2.76 TeV Measured with the ALICE Detector
  • 2016
  • Doctoral thesis (other academic/artistic)abstract
    • In high energy heavy ion collisions, the QCD matter undergoes a phase transition to a hot and dense strongly coupled Quark Gluon Plasma, where quarks and gluons are deconfined in a volume of nuclear dimensions. At intermediate pT, 2 < p T < 8 GeV/c, a decoupling from pure hydrodynamical flow is observed, most noticeable in central collisions, demonstrated by the peak in the ratio of baryons to mesons, e.g. the Λ/K0s ratio, compared to measurements in pp collisions. At high pT ( > 10 GeV/c), the particle production is dominated by jet fragmentation, where it is understood that these jets have suffered large energy losses propagating through the dense QGP. The goal of this thesis is to experimentally investigate the baryon-to-meson anomaly at intermediate pT, and to determine its origin, i.e. if it is an effect arising from the soft, collective, part (the bulk) of the medium, or from the hard processes (modified jet fragmentation). This will be done by analyzing central Pb–Pb collisions at sqrt(sNN) = 2.76 TeV from the ALICE experiment recorded in the 2011 heavy ion run period. For this analysis, a novel two-particle correlation technique called the η-reflection method is developed, where a separation can be made of the contributions from Λ and K0s particles produced in the soft underlying events from those which are produced in association with a high-pT trigger particle, representing a jet-like environment. The aim of this analysis is to separate the hadron production associated with the jet from that of the bulk, and to measure the Λ/K0s ratio at intermediate pT in the bulk and jet-like environment, to see how the baryon-to-meson anomaly differs in the two regions. The results show that at intermediate pT the hadron formation is dominated by the expanding and cooling Quark Gluon Plasma, giving rise to the anomalous overabundance of Λ over K0s which characterizes the inclusive results. The production of K0s and Λ associated with a high-pT trigger particle (presumably a leading hadron in a jet) is quite similar to that observed in pp collisions, i.e. unaffected by the processes in the dense, colored medium.

  • Sensitivity of EEHG simulations to dynamic beam parameters
  • 2023
  • In: 13th International Particle Accelerator Conference (IPAC'22) 12 - 17 June 2022, Bangkok, Thailand. - : IOP Publishing. - 1742-6588. ; 2420
  • Conference paper (peer-reviewed)abstract
    • Currently, the Free electron laser user facility FLASH at DESY is undergoing a significant upgrade involving the complete transformation of one of its beamlines to allow external seeding. With the Echo-Enabled Harmonic Generation (EEHG) seeding method, we aim for the generation of fully coherent XUV and soft X-ray pulses at wavelengths down to 4 nm. The generated FEL radiation is sensitive to various electron beam properties, e.g., its energy profile imprinted either deliberately or by collective effects such as Coherent Synchrotron Radiation (CSR). In dedicated particle tracking simulations, one usually makes certain assumptions concerning the beam properties and the collective effects to simplify implementation and analysis. Here, we estimate the influence of some of the common assumptions made in EEHG simulations on the properties of the output FEL radiation, using the example of FLASH and its proposed seeding beamline. We conclude that the inherent properties of the FLASH1 beam, namely the negatively chirped energy profile, has dominant effect on the spectral intensity profile of the radiators output compare to that of the CSR induced chirp.

  • Några aspekter på mångkulturens utmaningar - med särskilt fokus på islamisk rätt
  • 2013
  • In: Svensk Juristtidning. - Uppsala : Iustus förlag. - 0039-6591. ; , s. 877-886
  • Journal article (peer-reviewed)abstract
    • Sveriges omvandling till ett mångkulturellt, mångreligiöst och normativt pluralistiskt samhälle medför nya typer av utmaningar för den svenska rättsordningen. I mötet mellan kulturer betraktas sharialagar som en av de frågor som ger upphov till svårlösta problem och spänningar. Synen på sharia och den islamiska rättsordningen kantas dock av förutfattade meningar som behöver problematiseras mer grundligt. I artikel lyfter författaren fyra kritiska utgångspunkter som bör beaktas för att begripa den komplexitet som kännetecknar mötet mellan svensk och islamisk rätt.

  • True colors - experimental identification of hydrological processes at a hillslope prone to slide
  • 2014
  • In: Hydrology and Earth System Sciences. - : Copernicus GmbH. - 1027-5606 .- 1607-7938. ; 18:2, s. 875-892
  • Journal article (peer-reviewed)abstract
    • This study investigated runoff formation processes of a pre-alpine hillslope prone to slide. The experimental pasture plot (40mx60 m) is located in the northern front range of the Swiss Alps on a 30 degrees steep hillslope (1180m a.s.l., 1500+ mm annual precipitation). A gleysol (H-Go-Gr) overlies weathered marlstone and conglomerate of subalpine molasse. We conducted sprinkling experiments on a subplot (10 mx10 m) with variable rainfall intensities. During both experiments fluorescein line-tracer injections into the topsoil, and sodium chloride (NaCl) injections into the sprinkling water were used to monitor flow velocities in the soil. The observed flow velocities for fluorescein in the soil were 1.2 and 1.4x10(-3) ms(-1). The NaCl breakthrough occurred almost simultaneously in all monitored discharge levels (0.05, 0.25 and 1.0m depth), indicating a high-infiltration capacity and efficient drainage of the soil. These initial observations suggested "transmissivity feedback", a form of subsurface stormflow, as the dominant runoff process. However, the results of a brilliant blue dye tracer experiment completely changed our perceptions of the hillslope's hydrological processes. Excavation of the dye-stained soils highlighted the dominance of "organic layer interflow", a form of shallow subsurface stormflow. The dye stained the entire H horizon, vertical soil fractures, and macropores (mostly worm burrows) up to 0.5m depth. Lateral drainage in the subsoil or at the soil-bedrock interface was not observed, and thus was limited to the organic topsoil. In the context of shallow landslides, the subsoil (Go/Gr) acted as an infiltration and exfiltration barrier, which produced significant lateral saturated drainage in the topsoil (H) and possibly a confined aquifer in the bedrock.

  • Highly Transparent Films from Carboxymethylated Microfibrillated Cellulose : The Effect of Multiple Homogenization Steps on Key Properties
  • 2011
  • In: Journal of Applied Polymer Science. - : Wiley-Blackwell. - 0021-8995 .- 1097-4628. ; 119:5, s. 2652-2660
  • Journal article (peer-reviewed)abstract
    • We produced microfibrillated cellulose by passing carboxymethylated sulfite-softwood-dissolving pulp with a relatively low hemicellulose content (4.5%) through a high-shear homogenizer. The resulting gel was subjected to as many as three additional homogenization steps and then used to prepare solvent-cast films. The optical, mechanical, and oxygen-barrier properties of these films were determined. A reduction in the quantity and appearance of large fiber fragments and fiber aggregates in the films as a function of increasing homogenization was illustrated with optical microscopy, atomic force microscopy, and scanning electron microscopy. Film opacity decreased with increasing homogenization, and the use of three additional homogenization steps after initial gel production resulted in highly transparent films. The oxygen permeability of the films was not significantly influenced by the degree of homogenization, whereas the mean tensile strength, modulus of elasticity, and strain at break were increased by two or three extra homogenization steps.

  • ICBT in routine care : A descriptive analysis of successful clinics in five countries
  • 2018
  • In: Internet Interventions. - : Elsevier. - 2214-7829. ; 13, s. 108-115
  • Research review (peer-reviewed)abstract
    • Clinical trials have demonstrated the efficacy of internet delivered cognitive behaviour therapy (ICBT) for anxiety and depression. However, relatively little is known about the context, operations, and outcomes of ICBT when administered as part of routine care. This paper describes the setting, relationship to existing health services, procedures for referral, assessment, treatment, patients and outcomes of ICBT clinics in Sweden, Denmark, Norway, Canada and Australia. All five clinics provide services free or at low cost to patients. All have systems of governance to monitor quality of care, patient safety, therapist performance and data security. All five clinics include initial assessments by clinicians and between 10 and 20 min of therapist support during each week. Published reports of outcomes all demonstrate large clinical improvement, low rates of deterioration, and high levels of patient satisfaction. Services that require a face to face assessment treat smaller numbers of patients and have fewer patients from remote locations. The paper shows that therapist-guided ICBT can be a valuable part of mental health services for anxiety and depression. Important components of successful ICBT services are rigorous governance to maintain a high standard of clinical care, and the measurement and reporting of outcomes.

  • The genetic contribution of the NO system at the glutamatergic post-synapse to schizophrenia: Further evidence and meta-analysis
  • 2014
  • In: European Neuropsychopharmacology. - : Elsevier BV. - 0924-977X .- 1873-7862. ; 24:1, s. 65-85
  • Journal article (peer-reviewed)abstract
    • NO is a pleiotropic signaling molecule and has an important role in cognition and emotion. In the brain, NO is produced by neuronal nitric oxide synthase (NOS-I, encoded by NOS1) coupled to the NMDA receptor via PDZ. interactions; this protein-protein interaction is disrupted upon binding of NOS1 adapter protein (encoded by NOS1AP) to NOS-I. As both NOS1 and NOS1AP were associated with schizophrenia, we here investigated these genes in greater detail by genotyping new samples and conducting a meta-analysis of our own and published data. In doing so, we confirmed association of both genes with schizophrenia and found evidence for their interaction in increasing risk towards disease. Our strongest finding was the NOS1 promoter SNP rs41279104, yielding an odds ratio of 1.29 in the meta-analysis. As findings from heterologous cell systems have suggested that the risk allele decreases gene expression, we studied the effect of the variant on NOS1 expression in human post-mortem brain samples and found that the risk allele significantly decreases expression of NOS1 in the prefrontal cortex. Bioinformatic analyses suggest that this might be due the replacement of six transcription factor binding sites by two new binding sites as a consequence of proxy SNPs. Taken together, our data argue that genetic variance in NOS1 resulting in lower prefrontal brain expression of this gene contributes to schizophrenia liability, and that NOS1 interacts with NOS1AP in doing so. The NOS1-NOS1AP PDZ interface may thus well constitute a novel target for small molecules in at least some forms of schizophrenia. (C) 2013 Elsevier B.V. and ECNP. All rights reserved.
