Use of chlorpyrifos (CPF) has been curtailed due to its developmental neurotoxicity. In rats, postnatal CPF administration produces lasting changes in cognitive performance, but less information is available about the effects of prenatal exposure. We administered CPF to pregnant rats on gestational days (GD) 17-20, a peak period of neurogenesis, using doses(More)
Nicotinic acetylcholine and NMDA glutamate receptors play critical roles in memory function. The brain areas involved in their interaction are still under investigation. One likely area is the hippocampus. Ventral hippocampal administration of nicotinic antagonists impair memory. Hippocampal administration of NMDA antagonists also cause memory impairments.(More)
The Bacillus subtilis ResD-ResE two-component regulatory system activates genes involved in nitrate respiration in response to oxygen limitation or nitric oxide (NO). The sensor kinase ResE activates the response regulator ResD through phosphorylation, which then binds to the regulatory region of genes involved in anaerobiosis to activate their(More)
