    Författare :Anders Backlund; Ann-Cathrine Jungar; Hanna Bäck; Kaare Strøm; Södertörns högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; radical right; mainstream parties; pariah parties; anti-system parties; cordon sanitaire; party strategy; government formation; anti-pacts; coalition theory; spatial theories of party competition; policy co-optation; policy dimensionality; Sweden Democrats; Sweden; Sverigedemokraterna; högerradikala partier; pariapartier; anti-systempartier; partistrategi; regeringsbildning; koalitionsteori; Politics; Economy and the Organization of Society; Politik; ekonomi och samhällets organisering;

    Sammanfattning : In recent decades, established political parties across Europe have become increasingly challenged by a new party family: the radical right. In terms of how mainstream parties respond to this challenge, Sweden has been a puzzling case both in a comparative European perspective and in light of established theories of party competition.

  4. 3. Chemical defence in Norway spruce

    Författare :Marie Danielsson; Anna-Karin Borg-Karlson; Anders Backlund; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; volatiles; terpenes; green leaf volatiles; stilbenes; stress response; nepetalactone; Picea abies; Hylobius abietis; Cinara pilicornis; Oligonychus ununguis; Heterobasidion annosum; Chemistry; Kemi;

    Sammanfattning : Norway spruce (Picea abies) responds to stress by biosynthesis of chemical substances, which can deter invading insects or pathogens. Some of these substances are volatile and can be emitted to the surroundings while others are accumulated within the tree. LÄS MER

  5. 4. Phylogenies and Secondary Chemistry in Arnica (Asteraceae)

    Författare :Catarina Ekenäs; Katarina Andreasen; Anders Backlund; Lynn Bohs; Uppsala universitet; []
    Nyckelord :Biology; phylogeny; ITS; ETS; RPB2; sesquiterpene lactones; PCA; bioassay; NF-κB; neutrophil; chloroplast; Biologi; Arnica; Asteraceae;

    Sammanfattning : The genus Arnica (Asteraceae) was investigated for phylogenetic relationships and sesquiterpene lactone (STL) content with the aims to trace the evolutionary history of the genus and to investigate possible congruencies between DNA sequence data, secondary chemistry, and biological activity. Complex evolutionary patterns in Arnica are evident from phylogenetic analyses of chloroplast regions (the rpl16 and rps16 introns and the psbA–trnH, ycf4–cemA, and trnT–L spacers), nuclear ribosomal regions (the internal and external transcribed spacers) and the nuclear low-copy DNA region coding for the second largest subunit of RNA polymerase II (RPB2) between exons 17 and 23.

  7. 5. Exploring evolutionary and chemical space using chemoinformatic tools and traditional methods in pharmacognosy

    Författare :Astrid Henz Ryen; Anders Backlund; Thierry Kogej; Fernando B. Da Costa; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; angiosperm chemistry; physicochemical properties of plant specialized metabolites; chemical diversity; chemical space; sesquiterpene lactones; scaffold diversity; molecular framework; cluster analysis; ECFP6; Lindera benzoin; sesquiterpenes; anti-inflammatory; Farmakognosi; Pharmacognosy;

    Sammanfattning : The number of new drugs coming to the market is declining while interest in lead discovery from natural resources is seeing a revival. Although methods for isolation and identification of natural products have advanced tremendously, methods for selection of potential leads have fallen behind. LÄS MER
