It is suggested that masticatory dysfunction affects the central nervous system; however, the underlying mechanism remains unknown. Brain-derived neurotrophic factor (BDNF) and its receptor, TrkB, are known to play important roles in memory and learning. In this study, we examined the effects of mastication on memory, the expression levels of BDNF and TrkB,(More)
OBJECTIVE Malocclusion with deep overbite and facial esthetics improve when facial height is intentionally increased during orthodontic extrusion of the posterior teeth. Thus, a better understanding of post-treatment stability of increased occlusal vertical dimension (iOVD) in adult patients is important. We focused on the jaw-opening reflex (JOR), which(More)
Oxidative stress induced by the treatment with 100 µM hydrogen peroxide (H2O2) for 10 min enhances release of cytosolic proteins along with fibroblast growth factor 1 (FGF-1) from rat astrocytes without inducing apoptosis. FGF-1 promotes the generation of apolipoprotein E-containing high-density lipoprotein-like particles (apoE/HDL) in astrocytes, which(More)
