  1. 16. Macrophages, Nitric oxide synthases and Heme oxygenases: possible roles during peripheral nerve regeneration

    Författare :Sofia Magnusson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; satellite cells; peripheral ganglia; cell signalling; nerve regeneration; heme oxygenase; Macrophages; nitric oxide synthase; Animal physiology; Djurfysiologi;

    Sammanfattning : The purpose of this study was to investigate the suggestions that macrophages, and the systems generating nitric oxide (NO) and carbon monoxide (CO), i.e. nitric oxide synthases (NOS) and heme oxygenases (HO), could be important for peripheral nerve regeneration. LÄS MER

  3. 17. Calpain-Mediated Apoptosis in Motor Neurons of Adult Mouse Spinal Cord Slices

    Författare :HamidReza Momeni; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Calpain; Djurfysiologi; Animal physiology; Spinal cord; Organ culture; Mouse; Motor neurons; Caspase; Calpain inhibitor; Calpain activity; Apoptosis;

    Sammanfattning : Motor neuron degeneration is a critical phenomenon during spinal cord injuries and some neurodegenerative diseases. However, the mechanisms by which cell death is induced in these neurons are poorly understood. LÄS MER

  4. 18. The Polyamine Dependence of Cell Cycle Progression-Application in Breast Cancer Treatment

    Författare :Louise Myhre; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tissue culture; histochemistry; Histology; cytochemistry; onkologi; cancer; Cytologi; oncology; cancerology; Cytology; cell cycle kinetics; cell cycle regulatory proteins; polyamine analogues; DENSPM; CGP48664; DFMO; cell cycle regulation; Polyamines; breast cancer; Djurfysiologi; Animal physiology; vävnadskultur; Histologi; cytokemi; histokemi;

    Sammanfattning : In the normal functioning organism, there is a balance between cell proliferation, cell differentiation, and cell death. An imbalance in these processes results in different diseases. This thesis concerns the imbalance where there is too little cell death and cell differentiation with increased cell proliferation.

  5. 19. Intestinal barrier function in health and disease

    Författare :Pernilla Nejdfors; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; VIP.; PACAP; secretion; ion transport; urine reservoir; radiation therapy; ulcerative colitis; macromolecules; dextran; mannitol; Ussing chamber; Intestinal permeability; mucosa; Animal physiology; Djurfysiologi; Physiology; Fysiologi;

    Sammanfattning : The intestinal epithelium has the dual function of absorbing nutrients and water as well as being a barrier to potentially harmful substances such as macromolecules and bacteria. In the present thesis the barrier function of the intestinal mucosa was studied in vitro in Ussing diffusion chambers. LÄS MER

  7. 20. Gene expression in the dorsal root ganglion and the role of PAI-1 and amphiregulin during regeneration

    Författare :Anna Nilsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; Djurfysiologi; Animal physiology; DRG; micro-array; peripheral nerve regeneration; mouse;

    Sammanfattning : This thesis is concerned with two aspects of peripheral nerve injury. First the early changes in the gene expression of the dorsal root ganglion (DRG) in response to sciatic nerve injury as revealed by micro-array analysis. Second an examination of the effect of PAI-1 and amphiregulin on survival and axonal outgrowth from DRG. LÄS MER
