1. A radical view of haemoglobin - protein engineering and characterisation
Sammanfattning : In recent years shortages of donated blood have become a growing problem for health care systems world-wide. Blood substitutes based on human haemoglobin (Hb) could potentially ameliorate this situation. However, clinical trials have indicated problems due to e.g. LÄS MER
2. Delayed Cell Death after Traumatic Brain Injury : Role of Reactive Oxygen Species
Sammanfattning : Traumatic brain injury (TBI) is a leading cause of death and disability TBI survivors often suffer from severe disturbances of cognition, memory and emotions. Improving the treatment is of great importance, but as of yet no specific neuroprotective treatment has been found. LÄS MER
3. Cell-Penetrating Peptides for Mitochondrial Targeting
Sammanfattning : Mitochondria have simply been known as the cell’s powerhouse for a long time, with its vital function of producing ATP. However, substantially more attention was directed towards these organelles once they were recognized to perform several essential functions having an impact in cell biology, pharmaceutics and medicine.

4. A1M: a heme and radical binding protein. A study on structure, function and mechanisms
Sammanfattning : This thesis describes functional and structural studies of the human protein α1-microglobulin (A1M), an evolutionarily well-conserved 26 kDa plasma and tissue protein mainly synthesized in the liver. A1M belongs to the lipocalin protein family. Lipocalins share a very similar structur, an 8-stranded β-barrel forming a hydrophobic pocket. LÄS MER
5. Mechanisms of Brain Damage Following Focal Cerebral Ischemia: Changes in Ion Homeostasis and the Importance of Free Radical Formation
Sammanfattning : In this thesis mechanisms of neuronal damage were investigated in an experimental stroke model i.e focal ischemia. The influence of SD-induced calcium transients on neuronal damage were studied in animals with reduced energy supply. LÄS MER
