Neurotoxicity of Sub-Anesthetic Doses of Sevoflurane and Dexmedetomidine Co-Administration in Neonatal Rats

by SmartTots | Jul 11, 2020 | Research Articles

Abstract Background: Preclinical studies suggest that exposures of infant animals to general anesthetics cause acute neurotoxicity and affect their neurobehavioral development representing a potential risk to human infants undergoing anesthesia. Alternative or...

Acetyl-l-carnitine Does Not Prevent Neurodegeneration in a Rodent Model of Prolonged Neonatal Anesthesia

by SmartTots | Jul 11, 2020 | Research Articles

Abstract Many studies have shown that prolonged or repeated use of general anesthesia early in life can cause an increase in neurodegeneration and lasting changes in behavior. While short periods of general anesthesia appear to be safe, there is a concern about the...

Upregulation of miR-496 Rescues Propofol-Induced Neurotoxicity by Targeting Rho Associated Coiled-Coil Containing Protein Kinase 2 (ROCK2) in Prefrontal Cortical Neurons

by SmartTots | Jul 11, 2020 | Research Articles

Abstract Objective Early exposure to general anesthesia in children might be a potentially high-risk factor for learning and behavioral disorders. The mechanism of neurotoxicity induced by general anesthesia was not defined. miR-496 could regulate cerebral injury,...

Propofol Attenuates Isoflurane-Induced Neurotoxicity and Cognitive Impairment in Fetal and Offspring Mice

by SmartTots | Jul 11, 2020 | Research Articles

Abstract Background Anesthesia in pregnant rodents causes neurotoxicity in fetal and offspring rodents. However, the underlying mechanisms and targeted treatments remain largely to be determined. Isoflurane and propofol are among commonly used anesthetics. Thus, we...

Coenzyme Q10 alleviates sevoflurane-induced neuroinflammation by regulating the levels of apolipoprotein E and phosphorylated tau protein in mouse hippocampal neurons

by SmartTots | Jul 11, 2020 | Research Articles

Abstract Sevoflurane may exert neurotoxic effects on the developing brain. Coenzyme Q10 (CoQ10) has been reported to reduce sevoflurane anesthesia-induced cognitive deficiency in 6-day-old mice. However, its specific mechanisms remain unknown. Apolipoprotein E (ApoE)...
