Polychlorinated biphenyls (PCBs) are industrial chemicals that have been released into the environment, resulting in widespread and persistent contamination. PCBs exist as 209 different congeners depending on the chlorine substitution on the biphenyl rings, and the physical properties and toxic

Mice were gavaged with either (14)C-labeled 2,2'5,5' tetrachlorobiphenyl; 3,3',4,4' tetrachlorobiphenyl; or perfluorooctanoic acid. Absorption of these compounds was determined by assay of feces collected for 48 h after the gavage. Part of the animals received test diets containing olestra during

The bioavailability of coplanar 2,3',4,4',5-pentachlorobiphenyl (PCB118) and nonplanar 2,2',5,5'-tetrachlorobiphenyl (PCB52) from soils representing a range in organic carbon (OC), clay content and pH were investigated using an in vivo rat model and an in vitro physiologically based extraction test (PBET)

Polychlorinated biphenyls (PCBs) are ubiquitous environmental contaminants. Much of the research has focused on the carcinogenic potential of higher chlorinated PCBs, but accumulative evidence has shown that lower chlorinated PCB congeners have initiating and promoting activities. The goal of this

Aroclor-1254 (A-1254) is a commercial mixture of coplanar (dioxin-like) and non-coplanar (non dioxin-like) polychlorinated biphenyls (PCBs) affecting bovine oocyte in vitro maturation (IVM) and developmental competence. In the present study, the role of cumulus cell apoptosis in mediating the toxic
