Regulation of endocrine-disrupting chemicals is reviewed in terms of hazard assessment (regulatory toxicology) and risk assessment. The current range of regulatory general toxicology protocols can detect endocrine toxicity, but specific endocrine toxicology tests are required to confirm mechanisms (e.g. oestrogenic, anti-androgenic). Strategies for validating new endocrine toxicology protocols ...

ovarian cancer is one of the major causes of death in women. parabens are a class of chemicals widely used as preservatives in cosmetic and pharmaceutical products, they mimic estrogens, which are known to play a role in the development of different cancers in women. the aim of this study was to investigate the proliferative effects of methyl paraben (mp) and propyl paraben (pp) on human ovaria...

Dermal permeation through human epidermis and uptake into isolated human stratum corneum (SC) that was and was not delipidized were measured for 2 model compounds, 4-cyanophenol (CP) and methyl paraben (MP), from saturated aqueous solutions containing 1 or both compounds. Because the solutions were in equilibrium with the pure CP and MP, the thermodynamic activity of the compounds was constant....
