Tri-ortho-cresyl phosphate exposure leads to low egg production and poor eggshell quality via disrupting follicular development and shell gland function in laying hens.

Tri-ortho-cresyl phosphate (TOCP) has been used commercially as a plasticizer and a flame retardant, which has been reported to cause multiple toxicities in humans and other animals. However, the effect of TOCP on female reproductive system is still unclear. The aim of this investigation was to evaluate the reproductive toxicity of TOCP in female avian and investigate its molecular mechanism.

Verapamil abolished the enhancement of protein phosphorylation of brainstem mitochondria and synaptosomes from the hens dosed with tri-o-cresyl phosphate.

To explore the changes of the endogenous phosphorylation of brainstem mitochondrial and synaptosomal proteins in adult hens dosed with tri-o-cresyl phosphate (TOCP) following the development of organophosphate-induced delayed neurotoxicity (OPIDN). Verapamil (7mg/(kgday), i.m.

Effect of carbamate esters on neurite outgrowth in differentiating human SK-N-SH neuroblastoma cells.

Carbamate esters are widely used as pesticides and can cause neurotoxicity in humans and animals; the exact mechanism is still unclear. In the present investigation, the effects of carbamates at sublethal concentration on neurite outgrowth and cytoskeleton as well as activities of acetylcholinesterase (AChE) and neuropathy target esterase (NTE) in differentiating human SK-N-SH neuroblastoma cells were studied. The results showed that 50 microM of either aldicarb or carbaryl significantly decreased neurite length in the retinoic acid-induced differentiation of the neuroblastoma cells, compared to cells treated with vehicle.
