FOXO3 Regulates Sevoflurane-Induced Neural Stem Cell Differentiation in Fetal Rats

by SmartTots | Sep 1, 2021 | Research Articles

Abstract With the increase in fetal surgeries, the effect of maternal anesthesia on progeny has attracted much attention. Our previous studies have demonstrated that 3.5% sevoflurane maternal exposure resulted in over-activated autophagy and cognitive impairment in...

Inhibiting PDE7A Enhances the Protective Effects of Neural Stem Cells on Neurodegeneration and Memory Deficits in Sevoflurane-Exposed Mice.

by SmartTots | Sep 1, 2021 | Research Articles

Abstract Sevoflurane is widely used in general anesthesia, especially for children. However, prolonged exposure to sevoflurane is reported to be associated with adverse effects on the development of brain in infant monkey. Neural stem cells (NSCs), with potent...

Astrogliosis in juvenile non-human primates 2 years after infant anaesthesia exposure.

by SmartTots | Sep 1, 2021 | Research Articles

Abstract Background Infant anaesthesia causes acute brain cell apoptosis, and later in life cognitive deficits and behavioural alterations, in non-human primates (NHPs). Various brain injuries and neurodegenerative conditions are characterised by chronic astrocyte...

Maternal sevoflurane exposure induces temporary defects in interkinetic nuclear migration of radial glial progenitors in the fetal cerebral cortex through the Notch signalling pathway.

by SmartTots | Sep 1, 2021 | Research Articles

Abstract Objectives The effects of general anaesthetics on fetal brain development remain elusive. Radial glial progenitors (RGPs) generate the majority of neurons in developing brains. Here, we evaluated the acute alterations in RGPs after maternal sevoflurane...

Repeated neonatal sevoflurane induced neurocognitive impairment through NF-κB-mediated pyroptosis.

by SmartTots | Sep 1, 2021 | Research Articles

Abstract Background Exposure to general anesthesia (GA) during the postnatal period is associated with neuroinflammation and long-term neurocognitive impairment in preclinical and clinical settings. Pyroptosis is a novel type of programmed cell death that, along with...

The Increased Channel Activity of N-Methyl-D-Aspartate Receptors at Extrasynaptic Sites in the Anterior Cingulate Cortex of Neonatal Rats Following Prolonged Ketamine Exposure.

by SmartTots | Sep 1, 2021 | Research Articles

Abstract Background Ketamine is a dissociative anesthetic, commonly used for analgesia and anesthesia in a variety of pediatric procedures. It acts as a non-competitive antagonist to block ion channels of the N-methyl-D-aspartate receptors (NMDARs). Our previous study...
