1. Neurodevelopmental Consequences of Exposure to Paracetamol (Acetaminophen) and Related Drugs : Experimental studies in mice
Abstract : Paracetamol (acetaminophen) is the analgesic pharmaceutical most commonly used during pregnancy and early life. While therapeutic doses of paracetamol are considered harmless during these periods, recent findings in both humans and rodents suggest a link between developmental exposure to paracetamol and behavioral consequences later in life.

2. The Xenopus tropicalis model for developmental endocrine and reproductive toxicity : Histological and molecular endpoints for disrupted spermatogenesis
Abstract : Endocrine disrupting chemicals (EDCs) are linked to adverse effects in both humans and wildlife. There are however, large knowledge gaps regarding cause-effect and dose-response relationships between the interference with endocrine pathways and adverse effects in the organism, especially at puberty and in subsequent generations.

3. Progestagenic Aquatic Contaminants Act as Potent Androgens in Fish : Experimental Studies in Three-spined Stickleback and Zebrafish
Abstract : The extensive use of pharmaceuticals and their poor removal by wastewater treatment plants has led to the emergence of pharmaceutical compounds as global aquatic contaminants. Progestins, the synthetic analogues to progesterone (P4), are receiving increasing attention as contaminants and have been shown to impair reproduction in fish and amphibians at low ng L-1 concentrations.

4. Azoles and Contaminants in Treated Effluents Interact with CYP1 and CYP19 in Fish
Abstract : Numerous contaminants are present in mixtures in the aquatic environment. Among these are the azoles, a group of chemicals that includes both pharmaceuticals and pesticides. Azole fungicides are designed to inhibit lanosterol 14-demethylase (cytochrome P450 (CYP) 51), while other azoles are intended to inhibit aromatase (CYP19), i.e. READ MORE
