1. Developmental exposure to mixtures of environmental pollutants : Studies on metabolism, developmental processes, and reproductive organs in zebrafish and chicken embryos
Sammanfattning : 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. LÄS MER
2. Buellia species with pluriseptate spores and the Physciaceae (Lecanorales, Ascomycotina) : Taxonomic, phylogenetic and ultrastructural studies
Sammanfattning : This dissertation is primarily focused on the Buellia species with pluriseptate spores, often referred to the section or genus Diplotomma, and secondarily on the Physciaceae. An ultrastructural study at family level gives new information on spore characters. LÄS MER
3. Epigenetic Control of Mammalian Development : Studies on an imprinting control region
Sammanfattning : A subset of autosomal genes is preferentially or exclusively expressed from one of the parental alleles. This phenomenon, termed genomic imprinting, is highlighted by the neighboring Igf2 and H19 genes, which are monoallelically expressed on opposite parental chromosomes. These features are governed by a 2. LÄS MER
4. Cellular transport and secretion of the cyanobacterial neurotoxin BMAA into milk and egg : Implications for developmental neurotoxicity
Sammanfattning : 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. LÄS MER
5. Molecular evolutionary studies of genome degradation in bacteria
Sammanfattning : The genus Rickettsia belongs to the α-proteobacteria and consists of obligate intracellular bacteria, which often are pathogenic for humans. All Rickettsia have small genomes, highly adapted to an intracellular lifestyle. LÄS MER
