16. Nutrition in the second year of life. Effects of different milk compositions on dietary intakes, growth and metabolism
Abstract : In the diet for young children, whole cow´s milk is the major contributor of calories, protein and saturated fat, but it supplies little iron and polyunsaturated fat. Although several recommendations exist for the composition of formula, recommendations for the composition of milk for young children are lacking. READ MORE

17. Rate and Accuracy of Bacterial Protein Synthesis with Natural and Unnatural Amino Acids
Abstract : This thesis addresses different questions regarding the rate, efficiency, and accuracy of peptide bond formation with natural as well as unnatural amino acids: Which step is rate-limiting during peptide bond formation? How does the accuracy vary with different transfer RNAs (tRNAs) and codons and how is it relevant to the living cells? Does proofreading selection of codon reading occur in a single- or multi-step manner as theoretically suggested? How does the E. coli translation system discriminate unnatural amino acids? Based on that, how to improve the incorporation efficiencies of unnatural amino acids?Based on the study on pH dependence of peptide bond formation, we show that the rate of the chemistry of peptidyl transfer to aminoacyl-tRNA (AA-tRNA) Gly-tRNAGly or Pro-tRNAPro limits the rate of peptide bond formation at physiological pH 7.

18. Synthesis of biomolecules for nuclide therapy : Studies on amino acids, nucleosides and isoquinolines
Abstract : Nuclide therapy for cancer is based on the selective delivery of nuclide bearing compounds to tumour cells. Radionuclides, such as 125I, may be used, as well as stable isotopes, such as 10B, which is activated on site by an external neutron source. READ MORE
