1. Free radical mediated cellulose degradation
Abstract : This thesis addresses the mechanisms involved in cellulosedegradation in general and Totally Chlorine Free (TCF) bleachingof pulp in particular. The thesis shows that the cellulosedegradation during high consistency ozone bleaching is explainedby free radical chain reactions. READ MORE

2. Free radicals in cellular pathology : Mechanisms behind lipofucin formation in cultured myocardial cells
Abstract : Lipofuscin, or age pigment, may be defined as a yellowish-brown,autofluorescent, protein and lipid containing pigment that accumulates inthe lysosomal vacuome of a variety of post-mitotic cell types in man andanimals during aging. Lipofuscin is the end product of peroxidation,fragmentation and polymerization of proteins and lipids. READ MORE

4. Using de novo design proteins to explore tyrosine radicals and cation-π interactions
Abstract : Redox cofactors and amino-acid free radicals play important roles in biology. Although many of the same cofactors and amino acids that form these radicals are found across a broad range of biological systems, identical cofactors can have different reduction potentials. The local environment plays a role in defining these redox potentials. READ MORE

5. Mechanisms of Brain Damage Following Focal Cerebral Ischemia: Changes in Ion Homeostasis and the Importance of Free Radical Formation
Abstract : 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. READ MORE
