  1. 41. The Genetics of Systemic Lupus Erythematosus : The Specificity of IRF5 to SLE

    Författare :MV Prasad Linga Reddy; Marta Alarcön Riquelme; Dan Holmberg; Uppsala universitet; []
    Nyckelord :Molecular genetics; Systemic lupus erythematosus; Interferon regulatory factor 5; Transmission-Disequilibrium Test; Family-based association test; Linkage Disequilibrium; Hardy-Weinberg equilibrium; Genetik;

    Sammanfattning : The breakdown of self-tolerance is the main driving force behind susceptibility to SLE. When this occurs, T and B cells are activated in an uncontrolled manner and produce autoantibodies against self fragmented DNA, RNA and sometimes other parts of the cell such as cardiolipin, phosphatidylserine, etc. LÄS MER

  3. 42. Systematics and polyploid evolution in Potentilleae (Rosaceae)

    Författare :Magnus Lundberg; Torsten Eriksson; Jürg Schönenberger; Bengt Oxelman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Potentilleae; Fragariinae; Potentilla; Sibbaldia; Fragaria; Alchemilla; systematics; phylogeny; polyploidy; autopolyploidy; allopolyploidy; reticulate evolution; Systematics and phylogenetics; Systematik och fylogeni; växtsystematik; Plant Systematics;

    Sammanfattning : This thesis comprises studies of the phylogenetic relationships in the flowering plant clade Potentilleae in Rosaceae. The relationships were elucidated by using DNA sequence data from the nuclear genome as well as from the plastid genome. In particular, the focus of the studies was the investigation of allopolyploidy, i.e. LÄS MER

  4. 43. Genetic variability and cadmium metabolism and toxicity

    Författare :Gerda Rentschler; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cadmium; polymorphism; TFRC; SLC39A8; SLC39A14; MT1A;

    Sammanfattning : Abstract: Cadmium (Cd) is ubiquitous in the environment. Human exposure in non-smokers occurs mainly via intake of healthy food like vegetables, cereals, and shellfish. Adverse health effects on kidney and bone at low-level environmental Cd exposure are well-documented in adults. LÄS MER

  5. 44. "Ese terrible espejo" : autorrepresentación en la narrativa sobre el exilio del Cono Sur en Suecia

    Författare :Elena Lindholm Narvaez; Julian Vasquez Lopera; Eva Löfquist; Erna Pfeiffer; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; exile; narrative; Latin America; Sweden; self-representation; identity; gender; hybridity; heterotopia; memory; Spanish language; Spanska språket;

    Sammanfattning : The present dissertation deals with self-representation in a corpus consisting of narrative texts about the exile from Chile, Uruguay and Argentina, that reached Sweden during the 1970s and 1980s. The first part of the analysis focuses on the representation of discursive borders that enclose identity in exile in categories based on gender and ethnicity. LÄS MER

  7. 45. Soil phosphorus – a multidimensional resource that plays an important role for grassland plant species richness

    Författare :Jakob Sandberg; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; niche dimension; nutrient limitation; niche differentiation; competition; soil nitrogen; soil phosphorus; plant diversity; species richness; Grassland; land use; landscape scale;

    Sammanfattning : The semi-natural grassland habitats contain an important part of the plant diversity in Europe. Changes in farming practices have lead to drastic decreases in plant species richness. The aim of the present thesis is to contribute to the knowledge about mechanisms governing the plant species richness in grasslands with emphasis on soil nutrients. LÄS MER
