6. 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

7. 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

8. The role of leptin in zebrafish (Danio rerio) : Novel insights into appetite regulation and reproduction
Abstract : The hormone leptin is a peripheral metabolic signal and an important regulator of energy balance. In mammals, leptin acts on the appetite centers in the hypothalamus, causing anorexigenic functions by inhibiting food intake. It is also considered as a link between the nutritional status and the endocrine reproductive axis. READ MORE

9. The Otter (Lutra lutra) in Sweden : Contaminants and Health
Abstract : In the 1950s the otter started to decline in numbers and distribution in Sweden and other parts of Europe. In 1972 a game law came into force, listing otter as a species that if found dead should be reported and sent to the authorities. The numbers of dead otters reported from different areas indicate population status and distribution. READ MORE

10. Immune defense reactions in freshwater crayfish : Cellular components
Abstract : The freshwater signal crayfish, Pacifastacus leniusculus, is a well-established model for studying the immune system of invertebrates. Many important discoveries have been made in this species, among others related to the clotting reaction, hematopoiesis, the prophenoloxidase activating system, the functions of crustacean immune cells, and pathogen recognition.
