Bisphenol A induces feminization in Xenopus laevis tadpoles.
To evaluate possible estrogenic effects of bisphenol A (BPA) in an amphibian model, Xenopus laevis tadpoles were exposed to BPA and 17beta-estradiol (E2) during larval development. After… Expand

Carbamazepine (CBZ), Ibuprofen (IBU) and Bezafibrate (BEZ) were tested for their potential to bioaccumulate and provoke molecular changes in the non-target organism Dreissena polymorpha. mRNA changes… Expand
Water Quality and Heavy Metal Monitoring in Water, Sediments, and Tissues of the African Catfish Clarias gariepinus (Burchell, 1822) from the River Nile, Egypt
Water quality of the river Nile and trace elements of the water, sediments and fish tissues were investigated in the current work. Eighteen different sampling points were selected along the whole… Expand
Uncoupling protein 1 in fish uncovers an ancient evolutionary history of mammalian nonshivering thermogenesis.
Uncoupling proteins (UCPs) increase proton leakage across the inner mitochondrial membrane. Thereby, UCP1 in brown adipose tissue dissipates proton motive force as heat. This mechanism of… Expand
Androgenic and antiandrogenic activities in water and sediment samples from the river Lambro, Italy, detected by yeast androgen screen and chemical analyses.
The river Lambro is the most polluted tributary of the river Po in North Italy and was chosen as a representative water course discharging industrialized areas. Water and sediment samples of the… Expand
The development of functional digestive and metabolic organs in turbot, Scophthalmus maximus
The functional status of organ systems involved into the processing of exogenous food is critical for the survival and growth of fish early life stages. The present study on laboratory-reared larval… Expand
