  1. 21. Laboratory Soft X-Ray Cryo Microscopy: Source, System and Bio Applications

    Författare :Emelie Fogelqvist; Hans Hertz; David Attwood; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray microscopy; X-ray optics; Instrumentation; Laser plasma; Cryofixation; Tomography; Tomographic reconstruction; Autophagy; Immune synapse; Physics; Fysik; Physics;

    Sammanfattning : Soft x-ray microscopes routinely perform high-resolution 3D imaging of biological cells in their near-native environment with short exposure times at synchrotron radiation facilities. Some laboratory-sized microscopes are aiming to make this imaging technique more accessible to a wider scientific community. LÄS MER

  3. 22. Toward a tissue engineered blood vessel. Cell cultivation, hemodynamic influences and matrix production

    Författare :Sepideh Heydarkhan-Hagvall; Göteborgs universitet; []
    Nyckelord :tissue engineered blood vessel; co-culture vascular cells; angiogenic factors; ; hemodynamic; extracellular matrix; stem cells;

    Sammanfattning : Cardiovascular diseases are the leading causes of mortality in the western world. Thereplacement or repair of diseased blood vessels with human autografts (vein or arteries) orsynthetic vascular grafts (ePTFE or Dacron) has become a routine treatment. Autologous graftsare not always available in all patients. LÄS MER

  4. 23. Studies of the tumor-vasculature interface : role of TGF-beta 1-induced epithelial to mesenchymal transition

    Författare :Mei-Fong Pang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Tumor metastasis is a complex multistep process. Among key steps that occur during metastatic spread are acquisition of tumor cell motility, intravasation of tumor cells into blood or lymphatic vessels and extravasation of tumor cells at distal sites. However, the precise mechanisms that govern these metastatic steps remain elusive. LÄS MER

  5. 24. Tumor progression in the ovary and colon. The interaction of Wnt-signaling, transcription and formation of prostaglandins

    Författare :Katarina Rask; Göteborgs universitet; []
    Nyckelord :CCAAT Enhancer Binding Proteins C EBPs ; Wingless Wnt Wnt signaling pathway; Cyclooxygenases COXs ; colorectal cancer CRC ; epithelial ovarian cancer EOC ;

    Sammanfattning : Alterations in cell-cell adhesion, intracellular signaling and transcriptional regulation are common events during transformation of cells to the malignant phenotype. Different cellular defense mechanisms, e.g. inflammatory responses, mediated by prostaglandins, have also been associated with tumor development. LÄS MER

  7. 25. Towards Better Understanding of Etiological Mechanisms at the Neuromuscular Junction

    Författare :Evgenii Bogatikov; Anna Rostedt Punga; Klas Kullander; Viktorija Kenina; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neuromuscular junction; Muscle cells; Microelectrode array; MicroRNA; Clinical Neurophysiology; Klinisk neurofysiologi; Biomedical Laboratory Science; Biomedicinsk laboratorievetenskap;

    Sammanfattning : The neuromuscular junction (NMJ) serves as a model for understanding the mechanisms that determine communication between neurons and their target cells. Disorders of the NMJ can be either autoimmune or genetic (hereditary). LÄS MER
