  1. 1. Intraspecific variation in Rhinanthus angustifolius. Local adaptation, phenotypic plasticity and geographical structure

    Författare :Anneli Jonstrup; Biodiversitet; []
    Nyckelord :Ecotype; Local adaptation; Phenotypic plasticity; Parallel evolution; Geographical structure; Hemiparasite; Rhinanthus;

    Sammanfattning : Plant species often adapt to local environmental conditions, which can result in the formation of genetically and phenotypically distinct ecotypes. Ecotypes can evolve rapidly, and may be a first step in the process of ecological speciation. LÄS MER

  3. 2. Med kroppen som illustration : Hur förskolebarn prat-skapar naturvetenskap med hjälp av multimodala och kroppsförankrade förklaringar

    Författare :Anneli Bergnell; Lisbeth Åberg-Bengtsson; Ann-Katrin Svensson; Högskolan i Borås; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; preschool science education multimodality the concepts of stability; evaporation and water-cycle of the world talking science embodied illustrations förskolan naturvetenskap multimodala och kroppsförankrade illustrationer stabilitet; avdunstning; vattnets kretslopp prat-skapa naturvetenskap;

    Sammanfattning : The aim of this thesis is to combine three research areas, namely preschool, science and illustrations, in order to examine (a) how modes are combined when references to the body are made or the body as such are used to explain scientific concepts and phenomena in preschool science education, and (b) how do the children handle, explore, discuss and talk science when approaching multimodally illustrated scientific contents in the studied activities. Four studies were conducted, all of which were built on empirically generated questions and were theoretically grounded in cultural-historical and multimodal perspectives. LÄS MER

  4. 3. Ehrlichia in animals and humans

    Författare :Anneli Bjöersdorff; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; seroprevalence; humans; animals; granulocytic; ehrlichiosis; Ehrlichia phagocytophila; tick-borne; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Ehrlichia phagocytophila is a tick-borne pathogen of domestic animals, which has recently been acknowledged also as a human pathogen. It is a strictly intracellular bacterium, infecting granulocytes of the host, sometimes resulting in clinical disease - granulocytic ehrlichiosis - with manifestations ranging from mild flu-like conditions to severe infections with multi-organ failure and death.

  5. 4. Effects of over-stimulation by glucose on pancreatic beta-cell functioning : studies in vitro with diazoxide

    Författare :Anneli Björklund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :diabetes mellitus; diazoxide; hyperglycemia; insulin secretion; islets of Langerhans; over-stimulation;

    Sammanfattning : Long term hyperglycemia impairs pancreatic ß-cell function. In vivo studies in rats have shown a decreased glucose-induced insulin response in the perfused pancreas after high glucose infusions. LÄS MER

  7. 5. Antimicrobial activity of human seminal plasma and seminal plasma proteins

    Författare :Anneli Edström; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; semenogelin; antibacterial peptides; antifungal peptides; seminal plasma; antimicrobial peptides; vaginal pH; beta-microseminoprotein; peptides;

    Sammanfattning : Seminal plasma is semen without the spermatozoa. Human seminal plasma is a complex mixture of secretions from the sex accessory glands, mainly the seminal vesicles and the prostate. Seminal plasma has high protein content and it also contains ions, sugars and low molecular weight components. LÄS MER
