1. Developmental exposure to mixtures of environmental pollutants : Studies on metabolism, developmental processes, and reproductive organs in zebrafish and chicken embryos
Abstract : Humans and wildlife are continuously exposed to mixtures of environmental pollutants. Mixture toxicity can be challenging to predict due to interactions between chemicals and thus whole-mixture approaches are crucial in toxicology. READ MORE

2. Environmental pollutants and the reproductive system in birds : Developmental effects of estrogenic compounds
Abstract : A number of environmental pollutants have been shown to mimick the action of the female sex hormone estrogen and are, therefore, suspected to be responsible for reproductive abnormalities seen in wildlife. Test systems which can be used in hazard and risk assessment of chemicals with estrogenic effects are consequently needed. READ MORE

3. Cellular transport and secretion of the cyanobacterial neurotoxin BMAA into milk and egg : Implications for developmental neurotoxicity
Abstract : The cyanobacterial amino acid β-N-methylamino-L-alanine (BMAA) is a neurotoxin implicated in the etiology of neurodegenerative diseases. Cyanobacteria are cosmopolitan organisms present in various environments. READ MORE

4. Reactions to novelties : Developmental aspects
Abstract : The present thesis considers different aspects of infants' and children's reactions to novelties, that is, unfamiliar persons, objects, and situations. In Study I, the developmental phenomenon stranger wariness was investigated from a temperamental perspective. READ MORE

5. New roles for apical secretion and extracellular matrix assembly in Drosophila epithelial morphogenesis
Abstract : Branched tubular organs, such as the lung and vascular system fulfill the respiratory needs of most animals. Optimal tissue function relies on the uniform sizes and shapes of the constituting branches in each organ. READ MORE
