21. Laboratory Soft X-Ray Cryo Microscopy: Source, System and Bio Applications
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
22. Toward a tissue engineered blood vessel. Cell cultivation, hemodynamic influences and matrix production
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
23. Studies of the tumor-vasculature interface : role of TGF-beta 1-induced epithelial to mesenchymal transition
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
24. Tumor progression in the ovary and colon. The interaction of Wnt-signaling, transcription and formation of prostaglandins
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
25. Towards Better Understanding of Etiological Mechanisms at the Neuromuscular Junction
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
