1. Factors modulating tRNA biogenesis and function in Saccharomyces cerevisiae
Abstract : Transfer RNA (tRNA) genes are transcribed by RNA polymerase III as precursors that undergo multiple processing steps to form mature tRNAs. These steps include processing of the 5’ leader and 3’ trailer sequences, addition of a 3’ CCA tail, removal of introns, and formation of modified nucleosides. READ MORE

2. Nonionic surfactants : A multivariate study
Abstract : In this thesis technical nonionic surfactants are studied using multivariate techniques. The surfactants studied were alkyl ethoxylates (AEOs) and alkyl polyglucosides (APGs). The aquatic toxicity of the surfactants towards two organisms, a shrimp and a rotifer, was examined. The specified effect was lethality, LC50, as indicated by immobilisation. READ MORE

3. Oocyte maturation in a contaminated environment : effects of perfluoroalkyl substances on bovine early embryo development in vitro
Abstract : The content of this thesis is dedicated to female fertility, and more specifically the maturing oocyte. The aim was to investigate chemicals present in the direct environment of the oocyte and more specifically to investigate the sensitivity of the oocyte to perfluoroalkyl substances (PFASs) using a bovine in vitro embryo production model.

5. Anti-parasitic and anti-viral immune responses in insects
Abstract : Insects encounter many microorganisms in nature and to survive they have developed counter measures against the invading pathogens. In Drosophila melanogaster research on insect immunity has mainly been focused on infections by bacteria and fungi. READ MORE
