Methylmercury (Met-Hg) and ethylmercury (Et-Hg) are powerful toxicants with a range of harmful neurological effects in humans and animals. While Met-Hg is a recognized trigger of oxidative stress and an endocrine disruptor impacting neurodevelopment, the developmental neurotoxicity of Et-Hg, a metabolite of thimerosal (TM), has not been explored. We(More)
We have previously reported that perinatal exposure to hypergravity affects cerebellar structure and motor coordination in rat neonates. In the present study, we explored the hypothesis that exposure to hypergravity results in oxidative stress that may contribute to the decrease in Purkinje cell number and the impairment of motor coordination in(More)
We have previously reported that the developmental exposure of rats to altered gravity (1.65 g) from gestational day 8 to postnatal day 21 impacts motor functions and cerebellar structure. The present study examined whether the decrease in cerebellar mass accompanied by impaired performance on a rotorod in hypergravity-exposed rats was related to a decrease(More)
Mammalian brain development is regulated by the action of thyroid hormone (TH) on target genes. We have previously shown that the perinatal exposure to thimerosal (TM, metabolized to ethylmercury) exerts neurotoxic effects on the developing cerebellum and is associated with a decrease in cerebellar D2 activity, which could result in local brain T3(More)
In the present study, we examined the effect of perinatal Escherichia coli lipopolysaccharide (LPS) exposure on the developing rat cerebellum and tested the hypothesis that maternal infections impact brain structure and function by mechanisms involving increase in oxidative stress and changes in brain type 2 iodothyronine deiodinase (D2)- and thyroid(More)
