1. Exploring Catalytic Tellurium-Based Antioxidants : Synthesis and Evaluation
Abstract : This thesis is concerned with the synthesis and evaluation of various tellurium-based chain-breaking antioxidants. The purpose is to find novel regenerable compounds with improved radical-trapping capacity.In the first part of this work, we explore the possibilities to incorporate tellurium into tocopherols and aromatic amines.

2. Influence of Oxidative Stress on Muscle and Bone
Abstract : Reactive oxygen species (ROS) induce oxidative stress and although are primarily recognized for playing a deleterious biological role, they can be beneficial to cell systems. ROS are extremely short-lived and normally tightly regulated by antioxidant defence systems. READ MORE

5. Uptake, induction and distribution of ubiquinone and a-tocopherol
Abstract : Ubiquinone (UQ) and a-tocopherol are the major lipid-soluble antioxidants in animal tissues. Appropriate amounts of these lipids have to be present in tissues and subcellular membranes. Uptake from the diet was investigated and it was also analyzed to which extent the tissue amount may be increased by induction of biosynthesis. READ MORE
