- Conifers have dominated forests for more than 200 million years and are of huge ecological and economic importance. Here we present the draft assembly of the 20-gigabase genome of Norway spruce (Picea abies), the first available for any gymnosperm. The number of well-supported genes (28,354) is similar to the >100 times smaller genome of Arabidopsis thaliana, and there is no evidence of a recent whole-genome duplication in the gymnosperm lineage. Instead, the large genome size seems to result from the slow and steady accumulation of a diverse set of long-terminal repeat transposable elements, possibly owing to the lack of an efficient elimination mechanism. Comparative sequencing of Pinus sylvestris, Abies sibirica, Juniperus communis, Taxus baccata and Gnetum gnemon reveals that the transposable element diversity is shared among extant conifers. Expression of 24-nucleotide small RNAs, previously implicated in transposable element silencing, is tissue-specific and much lower than in other plants. We further identify numerous long (>10,000 base pairs) introns, gene-like fragments, uncharacterized long non-coding RNAs and short RNAs. This opens up new genomic avenues for conifer forestry and breeding.

- Abstract Objective. Severity of acute pancreatitis (AP) can vary from a mild to a fulminant disease with high morbidity and mortality. Cost analysis has, however, hitherto been sparse. The aim of this study was to calculate the cost of acute pancreatitis, both including hospital costs and costs due to loss of production. Material and methods. All adult patients treated at Skane University Hospital, Lund, during 2009-2010, were included. A severity grading was conducted and cost analysis was performed on an individual basis. Results. Two hundred and fifty-two patients with altogether 307 admissions were identified. Mean age was 60 ± 19 years, and 121 patients (48%) were men. Severe AP (SAP) was diagnosed in 38 patients (12%). Thirteen patients (5%) died. Acute biliary pancreatitis was more costly than alcohol induced AP (p < 0.001). Total costs for treating mild AP (MAP) in patients ≤65 years old was lower (p = 0.001) and costs for SAP was higher (p = 0.024), as compared to older patients. The overall hospital cost and cost for loss of production was per person in mean €5,100 ± 2,400 for MAP and €28,200 ± 38,100 for SAP (p < 0.001). The costs for treating AP during the two-year-long study period were in mean €9,762 ± 19,778 per patient. Extrapolated to a national perspective, the annual financial burden for AP in Sweden would be ∼ €38,500,000; corresponding to €4,100,000 per million inhabitants. Conclusions. The costs of treating AP are high, especially in severe cases with a long ICU stay. These results highlight the need to optimize care and continue the identification and focus on SAP, in order to try to limit organ failure and infectious complications.

- Adiponectin is secreted by adipose tissue and circulates in human plasma at high levels. Decreased adiponectin levels are associated with insulin resistance and obesity. The aim of this study was to investigate whether changes in serum adiponectin levels are related to the growth response, insulin levels and insulin resistance during growth hormone (GH) treatment.

Skolbränder och skolbrandsprevention : Underlag för planerade insatser enligt ”Karlstadsmodellen”
- 2009
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Kan man förebygga anlagda bränder och annan skadegörelse i skolor med miljöinriktade åtgärder? Den bedömningen gör man i Karlstads kommun med stöd i kriminologisk teori och erfarenheter från andra sektorer. Den traditionella ansatsen är annars är att kombinera brandtekniska åtgärder med ett mer individorienterat perspektiv riktat mot gärningspersoner. Syftet med föreliggande rapport är att ge en djupare belysning av den teoretiska grundvalen för en bredare miljöinriktad strategi, samt att peka på möjligheter att följa och utvärdera effekter av en lokal tillämpning. I bilaga redovisas även en forskningsöversikt kring den vetenskapliga evidens som idag föreligger beträffande miljöinriktad brottsprevention.

Trestad2 : Storstädernas satsning mot cannabis : delrapport för tiden jan 2012 - sep 2013.
- 2014
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Denna rapport är en halvtidsdokumentation av den storstadssatsning som mellan 2012 och 2014 genomförs i Stockholm, Göteborg och Malmö med syfte att minska användande av cannabis hos unga. Författarna till rapporten är medlemmar av den övergripande forskargrupp som utsetts av de tre medverkande storstäderna för att följa, dokumentera och utvärdera projektet som helhet. Den övergripande forskargruppen kommer att presentera sin slutrapport sommaren/hösten 2014. Halvtidsdokumentationen avser perioden från januari 2012 till september 2013 och har tillkommit på initiativ av den övergripande forskargruppen för att dokumentera storstadssatsningens förlopp samt för att skapa ett underlag som kan användas såväl under den återstående projekttiden, som vid slutrapportering av hela storstadssatsningen. Rapporten presenterades på ett seminarium med de tre medverkande städerna i Malmö den 3 februari 2014.

Tidskriftsartikel (refereegranskat)abstract
- Europe has a long history as a global center of scientific research, but not all European regions are alike. Regions such as ile de France and the corridor that stretches from Cambridge to Oxford via London produce a disproportionate share of Europe's science output. An econometric analysis sheds light on the factors that explain the spatial distribution of European science. One result is that the regional volume of Web of Science publications depends on the regional number of researchers in higher education institutions. This is however not the only cause of high output. Universities and their surrounding regions are slowly evolving institutional structures. Some regions host universities that are more than 500 years old. A second key result is that an increase in the age of a region's oldest university is associated with greater output, other things being equal. Third, interregional accessibility via road, rail, and air networks is important for small regions, but not for large ones. Conversely, regional high-tech R&D employment is important for large but not for small regions.

Unemployment in European regions: structural problems versus the Eurozone hypothesis

- Unemployment rates differ dramatically across European regions. This article analyses these differences by integrating institutional and spatial perspectives into a unified dynamic framework distinguishing between slow and fast processes of change. The framework forms the basis for an econometric model that is used to analyse labour market differences among European Nomenclature des unités territoriales statistiques 2 regions. The results of random-effects models indicate that four key factors—all of which are of the slowly changing type—explain a large part of the variation in unemployment as well as employment rates. Flexible labour market regulations and above-average levels of interpersonal trust are institutional factors that reduce unemployment. Accessibility factors such as inter-regional transport connectivity and local access to skilled workers have similarly substantial effects. Whether a region belongs to the Eurozone or not seems to be less important.
