    Sammanfattning : The woody tissues serve to stabilise plants, store nutrients and translocate water and minerals. The formation of wood, or ’secondary xylem’, follows a well-defined developmental gradient which is initiated by cell division activity in the vascular cambium. LÄS MER

  3. 2. Glacier-Ocean Interactions in the Arctic : Contemporary calving and frontal melt from field observations, remote sensing, and numerical modelling

    Författare :Felicity Alice Holmes; Nina Kirchner; Benedict T. I. Reinardy; Riko Noormets; Jason Briner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Glacier-ocean interactions; Arctic; Calving; naturgeografi; Physical Geography;

    Sammanfattning : Globally, glaciers are losing mass as a result of the changing climate, with this mass loss having a considerable societal impact through rising sea levels. Glaciers which terminate in the oceans are particularly vulnerable to changing external conditions as a result of high sensitivity at their marine margins. LÄS MER

  4. 3. Activation of human dendritic cells : role of the allergenic yeast Malassezia and NK cells

    Författare :Eva Buentke; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Antigen-presenting cells; atopic eczema dermatitis syndrome; cytokines; dendritic cells; Malassezia; NK cells; yeast;

    Sammanfattning : Immature bone marrow derived dendritic cells (DCs) patrol the periphery of our body, where they encounter and take up foreign antigens. Once activated, DCs migrate to regional lymph nodes to present peptides derived from these antigens to naive T cells, and elicit different T helper (Th) cell responses. LÄS MER
