Ameliorating the developmental neurotoxicity of chlorpyrifos: a mechanisms-based approach in PC12 cells.

abstract：OBJECTIVE:Animal feeding practices in the United States have changed considerably over the past century. As large-scale, concentrated production methods have become the predominant model for animal husbandry, animal feeds have been modified to include ingredients ranging from rendered animals and animal waste to antibi...
