Effects of parabens on antioxidant system and oxidative damages in Nile tilapia (Oreochromis niloticus)
(2018-10-30)
In this study, effects of parabens on antioxidant defenses and oxidative damages in gills and liver of Nile tilapia (Oreochromis niloticus) were evaluated. Adult Nile tilapia were exposed to methyl, ethyl, propyl, butyl ...
Computational predictions on the interactions of parabens with a dipalmitoyl phosphatidylcholine lipid bilayer and the human serum albumin protein
(Open Access Text, 2016-09)
Parabens are esters of para-hydroxybenzoic acid extensively used as preservatives in cosmetics and pharmaceutics. In the recent years their safe use has been questioned, mainly due to their estrogenic activity, their ...
Enhanced photoelectrocatalytic performance of TiO2 nanotube array modified with WO3 applied to the degradation of the endocrine disruptor propyl paraben
(2017-10-01)
We report on the photoelectrocatalytic degradation of the endocrine disruptor propyl paraben (PPB) using a TiO2 nanotube (TiO2-NT) electrode prepared via chemical anodization, and a TiO2-NT electrode modified with WO3 by ...
