Online Hemodiafiltration Reduces Bisphenol A Levels.

Several uremic toxins have been identified and related to higher rates of morbidity and mortality in dialysis patients. Bisphenol A (BPA) accumulates in patients with chronic kidney disease. The aim of this study is to demonstrate the usefulness of online hemodiafiltration (OL-HDF) in reducing BPA levels.

Effect of aroclor 1248 and two pure PCB congeners on phospholipase D activity in rat renal tubular cell cultures.

This paper elucidates the effect of different polychlorinated biphenyls (PCBs) on the phospholipase D (PLD) activity in soluble and particulate fractions of rat renal proximal tubular culture cells. Treatment with Aroclor 1248 (a commercial PCB mixture) caused a marked increase in the activity of PLD in intact renal tubular cells. The PLD activity was increased by Aroclor 1248 in the particulate fraction while the enzyme activity was unaffected in the soluble fraction.

Differential effects of PCBs on the induction of apoptosis machinery and PKCalpha translocation in rat renal tubular cell cultures.

We have demonstrated previously [Pérez-Reyes, P.L., Sánchez-Alonso, J.

Polychlorinated biphenyl mixtures (Aroclors) induce apoptosis via Bcl-2, Bax and caspase-3 proteins in neuronal cell cultures.

Polychlorinated biphenyls (PCBs) are a group of persistent and widely dispersed environmental pollutants, some of which may be neurotoxic. In the present study, we have investigated the effect of PCB commercial mixtures (Aroclors) on neuronal cell cultures by assessing cell viability and apoptotic cell death. We have combined morphological and biochemical techniques to establish the relevance of apoptosis in neuronal cell death induced by Aroclors.

Apoptosis-mediated neurotoxic potential of a planar (PCB 77) and a nonplanar (PCB 153) polychlorinated biphenyl congeners in neuronal cell cultures.

Polychlorinated biphenyls (PCBs) are ubiquitous environmental contaminants, some of which may be neurotoxic depending on the chemical structure of the congeners. This study investigated the neurotoxic potential of 3,3',4,4'-tetrachlorobiphenyl (TCB) (PCB 77, a non-ortho-substituted planar congener) and 2,2',4,4',5,5'-hexachlorobiphenyl (HCB) (PCB 153, a di-ortho-substituted nonplanar congener) by assessing cell viability and apoptotic cell death in neuronal cell cultures. We have combined morphological and biochemical techniques to establish the relevance of apoptosis in neuronal cell death induced by the two selected PCB congeners.
