A pronounced glutamate release has been related to neuronal death in several structures due to status epilepticus (SE). We investigated the glutamate uptake and release by both cortical and hippocampal synaptosome in pilocarpine model of epilepsy. Animals were submitted to long-lasting SE (12 h) induced by pilocarpine and compared with non-treated animals.(More)
OBJECTIVE The aim of the present study was to evaluate the symptoms of temporomandibular dysfunction (TMD) in patients with obstructive sleep apnea treated with long-term use of an oral appliance (OA) using a questionnaire based on the Helkimo Anamnestic Dysfunction Index. A further aim of the study was to evaluate the presence of daytime sleepiness using(More)
An increase in intra-neuronal Ca(2+) concentration has been associated to status epilepticus (SE). Ca(2+) is stored in the endoplasmic reticulum, mediated by the Ca(2+)-ATPases (SERCAs). Here we studied the Ca(2+)-ATPase activity and the SERCA2b distribution in the hippocampus of rats submitted to 5h of SE. The Ca(2+)-uptake was measured using [45Ca]CaCl(2)(More)
Diorganoyl dichalcogenide compouds can have antioxidant activity in different in vitro and in vivo models. Here, we have compared the potential antioxidant activity of 1-dinaphthyl diselenide (1-NapSe)2, 2-dinaphthyl diselenide (2-NapSe)2, 1-dinaphthyl distelluride (1-NapTe)2, 2-dinaphthyl ditelluride (2-NapTe)2 with their well-studied analogs diphenyl(More)
