  1. 1. Deciphering cell motility and spatial sensing of intestinal cell types using an ex vivo intestinal model

    Författare :Anna Webb; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The intestine is a highly organized tissue with two distinct regions: the crypt and the villus. When stem cells divide at the crypt bottom, half of their progeny migrates upwards towards the villus, where they differentiate into various cell types, including the abundant absorptive enterocytes.

  3. 2. Avian MHC : Characterization and expression patterns of classical and non-classical MHC-I genes

    Författare :Anna Drews; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MCH class I; Classical genes; Non-classical genes; Expression; Passerine birds;

    Sammanfattning : The function of the vertebrate immune system is to enable recognition and elimination of microorganisms that can cause harm (pathogens). A key component in adaptive immunity is the major histocompatibility complex (MHC) that codes for molecules with antigen presentation function. LÄS MER

  4. 3. The Importance of Dosimetry and Radiobiology in Nuclear Medicine : Quantitative methods and modelling

    Författare :Anna Stenvall; Lund Medicinsk strålningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear medicine; radionuclide therapy; radiopharmaceutical therapy; dosimetry; Monte Carlo modelling; radiobiology; ; γH2AX; DOTA-TATE; PET; SPECT;

    Sammanfattning : Nuclear medicine uses radioactive pharmaceuticals for diagnostic or therapeutic purposes. The ionizing radiation emitted from the radiopharmaceutical is partially absorbed within the patient's body and internal dosimetry is the method to estimate the absorbed dose to a tumour or risk organ.

  5. 4. Trajectories of Integration : Naturalization, Intermarriage and Education in Denmark, 1980-2015

    Författare :Anna Tegunimataka; Centrum för ekonomisk demografi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Naturalization; mother-tongue education; intermarriage; immigrant integration; Denmark;

    Sammanfattning : This dissertation examines socio-economic outcomes of first and second generation immigrants in Denmark and adds to our understanding of different trajectories of immigrant integration by studying policy and family relatedfactors. The association between family composition and socio-economic outcomes of the individual is in this thesis examined by studying the effects of intermarriage. LÄS MER

  7. 5. The potential of wetlands for mitigation of eutrophication and brownification

    Författare :Anna Borgström; Akvatisk ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Brownification; Constructed wetlands; Cyanobacteria; Eutrophication; Filamentous algae; Green algae; Macrophytes; Multifunctionality; Nitrogen; Phosphorus; Total organic carbon; Water color;

    Sammanfattning : Increasing nutrient concentrations (eutrophication) and water color due to dissolved organic matter (brownification) pose continuous threats to freshwater ecosystems worldwide, threatening ecosystem services like drinking water supply. Changing the increasing trends of eutrophication and brownification on our aquatic ecosystems is challenging. LÄS MER
