1. Studies of individual pancreatic -cells : Electrophysiological analysis of rhythmic behaviour and development of new techniques
Abstract : The insulin concentration in blood varies periodically, which is believed to prevent down-regulation of the hormone receptors. Loss of the regular insulin oscillations is considered to be an early sign of developing diabetes. READ MORE

4. Iron, Manganese and Iridium Complexes From Models of RNR and Catalase to Water Oxidation
Abstract : The focus of this thesis has been synthesise and study metal complexes that mimic the structure and function of the active site in two particular metalloenzymes, ribonucleotide reductase (RNR) and manganese catalase (MnCAT). These two metalloenzymes both have two transition metals ions in the cofactor: two manganese ions in MnCAT and either two iron, iron-manganese or two manganese ions in RNR. READ MORE
