BACKGROUND Ketamine induces neuroapoptosis in neonatal rodents. However, these experimental paradigms were performed without concurrent noxious stimulation, a condition that does not reflect the interaction of anesthesia and surgical stimulation. Noxious stimulation with and without concurrent analgesic drugs has been shown to have divergent patterns of(More)
BACKGROUND The pathophysiology of brain damage from hypoxia or ischemia has been ascribed to various mechanisms and cascades. Intracellular calcium overload and a calcium excitotoxic cascade have been implicated. It has been suggested that disturbances of endoplasmic reticulum calcium homeostasis are involved in the induction of neuronal cell injury. Two(More)
Previous randomized controlled trials have reported conflicting findings on the superiority of palonosetron over ramosetron for preventing postoperative nausea and vomiting (PONV). Therefore, the present systematic review was registered in PROSPERO (CRD42016038120) and performed to compare the efficacy of perioperative administration of palonosetron to that(More)
BACKGROUND Dexmedetomidine (DEX) has inherent neuroprotective properties that have been attributed to the activation of prosurvival kinases. However, the impact of supraclinical doses of DEX on neuroapoptosis and neuronal viability has not been determined. METHODS Rat pups and primary neuronal cells were treated with DEX or ketamine (KET) alone or in(More)
BACKGROUND Ketamine-induced neuroapoptosis has been attributed to diverse stress-related mechanisms. Glycogen synthase kinase-3β (GSK-3β) is a multifunctional kinase that is active in neuronal development and linked to neurodegenerative disorders. We hypothesized that ketamine would enhance GSK-3β-induced neuroapopotosis, and that lithium, an inhibitor of(More)
