2. The Human Spiral Ganglion
Abstract : Our knowledge of the fine structure of the Human Spiral Ganglion (HSG) is still inadequate and new treatment techniques for deafness using electric stimulation, call for further information and studies on the neuronal elements of the human cochlea. This thesis presents results of analyses of human cochlear tissue and specimens obtained during neurosurgical transpetrosal removal of life-threatening meningeomas. READ MORE

3. Reactive gliosis in the injured brain: The effect of cell communication and Nrf2-mediated cellular defence
Abstract : Stroke and other brain injuries trigger an extensive glial cell response referred to as reactive gliosis. Reactive gliosis is characterized by hypertrophic and proliferating astrocytes, proliferating microglia and NG2-positive cells, which eventually form a bordering glial scar around the damaged area.

4. Astrocytic communication and cell death during metabolic depression and oxidative stress
Abstract : Stroke is a major cause of death and adult disability in the western world. Most often, stroke is caused by the occlusion of a brain artery. Within the perfusion territory of the occluded vessel, various degrees of necrotic and delayed programmed cell death will occur if the occlusion persists, leading to expanding tissue damage.

5. Building Systems for Electronic Probing of Single Low Dimensional Nano-objects : Application to Molecular Electronics and Defect Induced Graphene
Abstract : Nano-objects have unique properties due to their sizes, shapes and structure. When electronic properties of such nano-objects are used to build devices, the control of interfaces at atomic level is required. READ MORE
