11. Energy Balance out of Balance after Severe Traumatic Brain Injury
Abstract : The overall aim of the research presented here was to expand the knowledge on metabolic course and nutritional outcome in patients with severe traumatic brain injury and to analyze the use and accuracy of different methods of assessment. Study I, a systematic review of 30 articles demonstrated consistent data on increased metabolic rate, of catabolism and of upper gastrointestinal intolerance in the majority of the patients during early post injury period.

12. EPR Studies of Ruthenium-Manganese Complexes as Biomimetic Models for Photosystem II - Approaching Artificial Photosynthesis
Abstract : In natural photosynthesis, solar energy is converted to chemical energy by photosynthetic reaction centers. In green plants and algae, Photosystem II (PSII) and Photosystem I (PSI) absorb light and utilize the charge separation reactions to convert solar energy to chemical energy. READ MORE

13. Effects of Protons and Small Alcohols on the Oxygen-Evolving Complex of Photosystem II
Abstract : Higher plants and algae use oxygenic photosynthesis to convert solar energy to reducing equivalents and chemical energy. The ultimate electron donor to oxygenic photosynthesis is water. Oxidation of water to oxygen occurs in the oxygen-evolving complex (OEC) in Photosystem II (PSII). The OEC is composed of four Mn atoms, Ca2+ and Cl-. READ MORE

14. On the antiporter-like subunits of respiratory chain Complex I - implications for the evolution and coupling mechanism of the NADH:quinone oxidoreductase enzyme complex
Abstract : Complex I or NADH:quinone oxidoreductase is the largest enzyme complex, but the least understood energy coupling site in the respiratory chain of mitochondria and bacteria. No high-resolution structural information exists for this enzyme and the molecular mechanism that couples electron transfer and proton pumping is not understood. READ MORE

15. Photosynthetic Oxygen Evolution - EPR studies of the manganese cluster of photosystem II
Abstract : In this thesis, a new electron paramagnetic resonance (EPR) signal from photosystem II is presented. The signal is shown to originate from the S0 oxidation state of the oxygen-evolving complex (OEC). READ MORE
