A neurohistopathologic study was conducted to determine the types and incidence of spontaneous lesions of the nervous system in healthy adult hens. Tissues examined were brain, three levels of spinal cord, and sciatic nerves from 92 healthy commercial hens from a single commercial egg-production
N-Butylbenzenesulfonamide (NBBS) is widely used as a plasticizer in polyacetals, polyamides, and polycarbonates and has been found in ground water and effluent from wastewater treatment sites. The compound is lipophilic and distributes rapidly to the brain but also clears rapidly and shows little
Thyroid hormones (TH) regulate biological processes implicated in neurodevelopmental disorders and can be altered with environmental exposures. Developmental exposure to the dioxin-like compound, 3,3',4,4'-tetrachloroazobenzene (TCAB), induced a dose response deficit in serum T4 levels with no
Tris(2-chloroethyl) phosphate (TRCP), a flame-retardant plasticizer used in plastics, polymeric foams, and synthetic fibers, was studied as part of the National Toxicology Program's class study of trisalkyl phosphate flame retardants. Toxicology and carcinogenesis studies were conducted by
The neuroprotective effects of two isomers (Z- and E-) of ajoene, a major compound in oil-macerated garlic products, against ischemic damage were investigated in the gerbil hippocampus. Vehicle (corn oil), Z- or E-ajoenes (25 mg/kg) was orally administered 30 min prior to the induction of transient
Stimulation of Na+ /H+ exchanger isoform 1 (NHE1) in astrocytes causes ionic dysregulation under ischemic conditions. In this study, we created a Nhe1flox/flox (Nhe1f/f ) mouse line with exon 5 of Nhe1 flanked with two loxP sites and selective ablation of Nhe1 in astrocytes was achieved by crossing
