- BACKGROUND: The 65-kD isoform of glutamic acid decarboxylase (GAD65) is a major autoantigen in type 1 diabetes. We hypothesized that alum-formulated GAD65 (GAD-alum) can preserve beta-cell function in patients with recent-onset type 1 diabetes.METHODS: We studied 334 patients, 10 to 20 years of age, with type 1 diabetes, fasting C-peptide levels of more than 0.3 ng per milliliter (0.1 nmol per liter), and detectable serum GAD65 autoantibodies. Within 3 months after diagnosis, patients were randomly assigned to receive one of three study treatments: four doses of GAD-alum, two doses of GAD-alum followed by two doses of placebo, or four doses of placebo. The primary outcome was the change in the stimulated serum C-peptide level (after a mixed-meal tolerance test) between the baseline visit and the 15-month visit. Secondary outcomes included the glycated hemoglobin level, mean daily insulin dose, rate of hypoglycemia, and fasting and maximum stimulated C-peptide levels.RESULTS: The stimulated C-peptide level declined to a similar degree in all study groups, and the primary outcome at 15 months did not differ significantly between the combined active-drug groups and the placebo group (P=0.10). The use of GAD-alum as compared with placebo did not affect the insulin dose, glycated hemoglobin level, or hypoglycemia rate. Adverse events were infrequent and mild in the three groups, with no significant differences.CONCLUSIONS: Treatment with GAD-alum did not significantly reduce the loss of stimulated C peptide or improve clinical outcomes over a 15-month period.

Evaluation of forest snow processes models (SnowMIP2)
- 2009
-
Ingår i: Journal of Geophysical Research. - : American Geophysical Union (AGU). - 0148-0227 .- 2156-2202. ; 114:6

Tidskriftsartikel (refereegranskat)abstract
- Thirty-three snowpack models of varying complexity and purpose were evaluated across a wide range of hydrometeorological and forest canopy conditions at five Northern Hemisphere locations, for up to two winter snow seasons. Modeled estimates of snow water equivalent (SWE) or depth were compared to observations at forest and open sites at each location. Precipitation phase and duration of above-freezing air temperatures are shown to be major influences on divergence and convergence of modeled estimates of the subcanopy snowpack. When models are considered collectively at all locations, comparisons with observations show that it is harder to model SWE at forested sites than open sites. There is no universal "best'' model for all sites or locations, but comparison of the consistency of individual model performances relative to one another at different sites shows that there is less consistency at forest sites than open sites, and even less consistency between forest and open sites in the same year. A good performance by a model at a forest site is therefore unlikely to mean a good model performance by the same model at an open site (and vice versa). Calibration of models at forest sites provides lower errors than uncalibrated models at three out of four locations. However, benefits of calibration do not translate to subsequent years, and benefits gained by models calibrated for forest snow processes are not translated to open conditions.

God havsmiljö 2020 : Marin strategi för Nordsjön och Östersjön Del 3: Övervakningsprogram
- 2014
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Havsmiljöförordningens övergripande mål är att upprätthålla eller uppnå en god miljöstatus i de svenska förvaltningsområdena Nordsjön och Östersjön till år 2020. En av uppgifterna i den första förvaltningsperioden är att fastställa övervakningsprogram.God miljöstatus baseras på ett ramverk av så kallade deskriptorer som anges i havsmiljödirektivet, det vill säga det EU-direktiv som i Sverige genomförs genom havsmiljöförordningen. Deskriptorerna beskriver god miljöstatus på en övergripande nivå för elva temaområden. Till varje deskriptor hör en rad kriterier som anger vad som ska ingå i en bedömning av miljöstatus. Utifrån de elva deskriptorerna har Sverige fastställt 13 övervakningsprogram. Sex program utgår ifrån olika biodiversitetsteman som berörs av en upp till tre deskriptorer, medan de övriga sju programmen utgår ifrån de deskriptorer som är mer inriktade mot belastning och miljöförändring.För varje program har ett antal underprogram föreslagits baserat på den nuvarande övervakningen och/eller planerad övervakning. Övervakning som ingår i programmen ska vara pågående och data ska vara tillgängliga. I programmen ingår nationell och regional miljöövervakning inklusive verksamhetsutövares recipientkontroll. Dessutom ingår annan typ av datainsamling som till exempel inventeringar av tumlare och uppgifter om omfattningen av mänskliga aktiviteter som orsakar belastning och miljöförändringar. Enligt havsmiljödirektivet ska övervakningen fånga upp tillstånd och miljöförändringar, belastning och omfattning av aktiviteterna som orsakar belastningen samt effekter av åtgärder. Eftersom nästa steg i havsförvaltningscykeln är att fastställa åtgärdsprogram kommer övervakning för att följa upp åtgärder att läggas till övervakningsprogrammen först under nästa förvaltningscykel.I beskrivningarna av programmen framgår hur den nuvarande övervakningen motsvarar de krav som ställs på dataunderlag genom havsmiljödirektivets bilaga III samt genom deskriptorer, kriterier, indikatorer och beslutade miljökvalitetsnormer. I dagens övervakning saknas bland annat tillräcklig övervakning för uppföljning av livsmiljöers tillstånd och utbredning. För marint avfall, buller och främmande arter saknas nationellt samordnad övervakning, men det görs regionala insatser och ett antal projekt har genomförts eller påbörjats för att öka kunskapen om hur övervakning bäst ska utformas. För de program som har pågående övervakning beskrivs utvecklingsbehoven för att förbättra underlaget för de återkommande tillståndsbedömningarna.Övervakningsprogrammet som fastställs under 2014 utgör således inte ett fast program för kunskapsinhämtning. Bristerna kommer att beaktas i det fortsatta genomförandet av havsmiljöförordningen där utveckling av indikatorer och övervakning kommer att ske kontinuerligt.

A Study of Skin-Close Heat and Moisture with Different Types of Backpacks in Cycling
- 2020

Ingår i: The 13th Conference of the International Sports Engineering Association. - Basel Switzerland : MDPI.

Konferensbidrag (refereegranskat)abstract
- The aim of this project was to evaluate effects of backpacks with different design intended for use during cycling on skin-close temperature and relative humidity, oxygen uptake, heart rate and aerodynamic drag. Seven subjects took part in the study cycling on a mountain bike mounted on a “smart trainer” placed on a force plate in a wind tunnel. Three series of experiments were carried out: without backpack, with conventional backpack and with a backpack having innovative rear panel design. As hypothesized, the results showed that an innovatively designed backpack with the ducts deflecting part of the airflow towards some areas of the user’s back provided lower temperature and relative humidity for the microclimate compared to a conventional backpack without airflow channels. Further, reference tests without any backpack resulted in the lowest temperature and humidity. However, no differences were found between the three tests for oxygen uptake, heart rate and aerodynamic drag.

Collection of Metaphors for Human-Robot Interaction

Konferensbidrag (refereegranskat)abstract
- The word "robot"frequently conjures unrealistic expectations of utilitarian perfection: tireless, efficient and flawless agents. However, real-world robots are far from perfect - they fail and make mistakes. Thus, roboticists should consider altering their current assumptions and cultivating new perspectives that account for a more complete range of robot roles, behaviors, and interactions. To encourage this, we explore the use of metaphors for generating novel ideas and reframing existing problems, eliciting new perspectives of human-robot interaction. Our work makes two contributions. We (1) surface current assumptions that accompany the term "robots,"and (2) present a collection of alternative perspectives of interaction with robots through metaphors. By identifying assumptions, we provide a comprehensible list of aspects to reconsider regarding robots' physicality, roles, and behaviors. Through metaphors, we propose new ways of examining how we can use, relate to, and co-exist with the robots that will share our future.

- Inhibition of histone deacetylases may be an important target in patients with myeloproliferative neoplasms. This investigator-initiated, non-randomized, open-label phase II multi-centre study included 63 patients (19 essential thrombocythaemia, 44 polycythaemia vera) from 15 centres. The primary objective was to evaluate if vorinostat was followed by a decline in clonal myeloproliferation as defined by European Leukaemia Net. Thirty patients (48%) completed the intervention period (24 weeks of therapy). An intention-to-treat response rate of 35% was identified. Pruritus was resolved [19% to 0% (P=0.06)] and the prevalence of splenomegaly was lowered from 50% to 27% (P=0.03). Sixty-five per cent of the patients experienced a decrease in JAK2 V617F allele burden (P=0.006). Thirty-three patients (52% of patients) discontinued study drug before end of intervention due to adverse events (28 patients) or lack of response (5 patients). In conclusion, vorinostat showed effectiveness by normalizing elevated leucocyte and platelet counts, resolving pruritus and significantly reducing splenomegaly. However, vorinostat was associated with significant side effects resulting in a high discontinuation rate. A lower dose of vorinostat in combination with conventional and/or novel targeted therapies may be warranted in future studies.

- YKL-40 regulates vascular endothelial growth factors and induces tumor proliferation. We investigated YKL-40 before and after treatment with vorinostat in 31 polycythemia vera (PV) and 16 essential thrombocythemia (ET) patients. Baseline PV patient levels were 2 times higher than in healthy controls (P<0.0001) and 1.7 times higher than in ET (P = 0.02). A significant correlation between YKL-40 at baseline and neutrophils, CRP, LDH, JAK2V617F and platelets in PV patients was observed, as well as a significantly greater reduction of YKL-40 levels in PV patients responding to therapy. YKL-40 might be a novel marker of disease burden and progression in myeloproliferative neoplasms.

-
Ingår i: ACM International Conference Proceeding Series. - New York, NY, USA : ACM.
-
Konferensbidrag (refereegranskat)abstract
- The combination of Virtual Reality and Biosignals is a developing area of research, and a design space with promising possibilities and implications for art and creativity. In this demonstration, we focus on supporting an engaging personal creative experience in Virtual Reality, making use of respiration, heart-rate, and gestures. The interactive modalities afford a new medium for art-making, and are potentially conducive to well-being. Our interactive experience stems from a Research through Design process and informed by Soma Design, interviews with artists, and preliminary user studies. We present Nebula - an immersive VR experience aimed at supporting a user's somaesthetic appreciation and well-being.
