Propofol and Sevoflurane Anesthesia in Early Childhood Do Not Influence Seizure Threshold in Adult Rats.

by SmartTots | Aug 31, 2022 | Research Articles

Abstract Experimental studies have demonstrated that general anesthetics administered during the period of synaptogenesis may induce widespread neurodegeneration, which results in permanent cognitive and behavioral deficits. What remains to be elucidated is the extent...

Sevoflurane Exposure in the Developing Brain Induces Hyperactivity, Anxiety-Free, and Enhancement of Memory Consolidation in Mice.

by SmartTots | Aug 31, 2022 | Research Articles

Abstract Background: Sevoflurane exposure at brain developmental stages has been reported to induce neurotoxicity and, subsequently, results in learning deficits at the juvenile age. In this study, we aimed to investigate the effects of prior early-age sevoflurane...

Fentanyl induces autism-like behaviours in mice by hypermethylation of the glutamate receptor gene Grin2b.

by SmartTots | Aug 31, 2022 | Research Articles

Abstract Background: Environmental factors contribute to autism spectrum disorder. Fentanyl, one of the most widely used opioid analgesics in anaesthesia, can induce neurotoxicity, but its role in autism remains unknown. We determined whether fentanyl induced...

Multiple exposures to sevoflurane across postnatal development may cause cognitive deficits in older age.

by SmartTots | Aug 31, 2022 | Research Articles

Abstract Background: The aim of the study was to determine the effects of repeated anesthesia exposure across postnatal development. Methods: Seventy-two newborn Sprague-Dawley rats were randomly divided into Sev group and Con-aged group. Sev groups were exposed to...

Mitochondria-Related Ferroptosis Drives Cognitive Deficits in Neonatal Mice Following Sevoflurane Administration.

by SmartTots | Aug 31, 2022 | Research Articles

Abstract Multiple sevoflurane exposure may result in cognitive deficits in neonatal animals. This study attempted to investigate the potential mechanism of sevoflurane-induced neurotoxicity in developing hippocampus. Neonatal animals received sevoflurane anesthesia,...

MicroRNA-424-5p Alleviates Isoflurane Anesthesia-Induced Neurotoxicity in Human Embryonic Stem Cell-Derived Neurons by Targeting FASN.

by SmartTots | Aug 31, 2022 | Research Articles

Abstract Isoflurane (ISO) is a type of anesthetic that might cause neurotoxicity in children. Although miR-424-5p is considerably downregulated in ISO-treated rat brain samples, its physiological role in ISO-induced neuronal injury in human embryonic stem cell-derived...
