1. Exposure to inorganic arsenic in pregnancy and metabolism-nutrition interaction
Abstract : Inorganic arsenic is metabolized by most mammals, including humans, via alternating reduction and oxidative methylation with S-adenosylmethionine as main methyl donor. Thus, it seems likely that it is influenced by the availability of methyl groups. READ MORE

2. Conformationally Constrained Oligonucleotides for RNA Targeting
Abstract : A short oligonucleotide sequence as in a single-stranded antisense oligo nucleotides (AON) or in double-stranded small interfering RNAs (siRNA) can modulate the gene expression by targeting against the cellular mRNA, which can be potentially exploited for therapeutic purposes in the treatment of different diseases. In order to improve the efficacy of oligonucleotide-based drugs, the problem of target affinity, nuclease stability and delivery needs to be addressed. READ MORE

4. Evidence for adaptive variation at the genes coding for cytosolic phosphoglucose isomerase (PGIC) in Festuca ovina L
Abstract : The gene (Pgi) encoding the enzyme phosphoglucose isomerase (PGI) which plays a central role in the main pathways of carbon metabolism has been shown to be of adaptive significance in a wide range of different species. Earlier studies of enzyme electromorph variation in the grass Festuca ovina suggest that variation in cytosolic PGI (PGIC) may be involved in the adaptive response of F. READ MORE

5. Bonding and Diffusion of Molecules in Zeolites by ESR and ENDOR
Abstract : This thesis studies bonding and diffusion of molecules in zeolites by Electron Spin Resonance (ESR) and Electron Nuclear Double Resonance (ENDOR). In the first part an introduction is given. In the second part (chapter 2) the detailed structure of a Cu2+ complex with water molecules in Cu-ZSM-5 zeolite was characterized with ENDOR at 4 K.
