  1. 1. Characterization of New Players in Planar Polarity Establishment in Arabidopsis

    Författare :Stefano Pietra; Markus Grebe; Niko Geldner; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SABRE; planar polarity; CLASP; cell division orientation; microtubule cytoskeleton; actin; AIP1; patterning; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Sammanfattning : Coordinated polarity and differentiation of cells in the plane of a tissue layer are essential to the development of multicellular organisms. Arabidopsis thaliana root hairs and trichomes provide model systems to study the pathways that control planar polarity and cell fate specification in plants. LÄS MER

  3. 2. Characterisation of actin cytoskeletal functions and interactions during planar polarity formation in Arabidopsis

    Författare :Christian Kiefer; Markus Grebe; Tijs Ketelaar; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The establishment of cell and tissue polarity is essential for the development of eukaryotic organisms including plants and animals. When cell polarity is uniformly organised within a plane of a single tissue layer, it is referred to as planar polarity. LÄS MER

  4. 3. Diffusion MRI: Aspects of Reproducibility and Novel Segmented 2D and 3D Approaches for Higher Resolution and Geometric Fidelity

    Författare :Jens Johansson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diffusion-weighted imaging; 3D-DWI; Time-Dependent ADC; DWi; Diffusion Time; Multi-Shot DWI; Echo- Planar Imaging; Geometric Distortion;

    Sammanfattning : Diffusion-weighted imaging (DWI) is a very useful tool for non-invasive imaging and clinical investigation of the human body. It provides data of the water diffusion process. LÄS MER

  5. 4. Electrochemical Studies of Redox Properties and Diffusion in Self-Assembled Systems

    Författare :Johan Kostela; Mats Almgren; Maja Elmgren; Martin Malmsten; Renata Bilewicz; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; electrochemistry; self-assembly; bicontinuos cubic phase; redox potential; diffusion; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : In this thesis electron transfer reactions and diffusion of redox molecules in three different types of self-aggregated structures are investigated. Electrochemistry was used to investigate the redox potential and diffusion coefficients for redox active molecules with different polarity. The first aggregate system studied was the micellar phase.

  7. 5. Structural and functional analysis of WNT receptors : with emphasis on FZD6

    Författare :Julian Petersen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Many cellular processes are dependent on the activation of G protein-coupled receptors (GPCRs). The development of drugs that can specifically target GPCRs and their corresponding signalling cascades is of high interest. LÄS MER
