Tetraethylammonium chloride reduces anaesthetic-induced neurotoxicity in Caenorhabditis elegans and mice.

by SmartTots | Mar 2, 2022 | Research Articles

Abstract Background: If anaesthetics cause permanent cognitive deficits in some children, the implications are enormous, but the molecular causes of anaesthetic-induced neurotoxicity, and consequently possible therapies, are still debated. Anaesthetic exposure early...

Sevoflurane induced neurotoxicity in neonatal mice links to a GSK3β/Drp1-dependent mitochondrial fission and apoptosis.

by SmartTots | Mar 2, 2022 | Research Articles

Abstract Mitochondria damage and apoptosis were found associated with sevoflurane induced neurotoxicity in developing brains of rodent and neuro cell lines. The detailed upstream mechanism remains unclear. This study explored whether sevoflurane induces neurotoxicity...

Hippocampal SIRT1-Mediated Synaptic Plasticity and Glutamatergic Neuronal Excitability Are Involved in Prolonged Cognitive Dysfunction of Neonatal Rats Exposed to Propofol.

by SmartTots | Mar 2, 2022 | Research Articles

Abstract Neonates who receive repeated or prolonged general anesthesia before the age of 4 are at a significantly higher risk of developing cognitive dysfunction later in life. In this study, we investigated the effects of repeated neonatal propofol exposure on...

Repeated exposure to sevoflurane in neonatal rats impairs cognition in adulthood via the PKA-CREB-BDNF signaling pathway.

by SmartTots | Mar 2, 2022 | Research Articles

Abstract Sevoflurane (Sev) anesthesia is widely used in pediatrics due to its low blood-gas partition coefficient and lack of pungency. However, Sev treatment may lead to cognitive dysfunction in later life. The current study administered Sev to neonatal rats to...

Does inflammation mediate behavioural alterations in anaesthesia-induced developmental neurotoxicity?

by SmartTots | Mar 2, 2022 | Research Articles

Abstract Anaesthesia exposure early in life potentially impairs neurobehavioural development. A recent study in the Journal investigated the possibility that progesterone mitigates anaesthesia-induced developmental neurotoxicity in neonatal rats exposed to...

Neonatal isoflurane exposure disturbs granule cell migration in the rat dentate gyrus.

by SmartTots | Mar 2, 2022 | Research Articles

Abstract It has been reported that neonatal isoflurane exposure causes behavioral abnormalities following neurodegeneration in animals and gamma-aminobutyric acid type A (GABAA) receptor activation during the synaptogenesis is considered to be one possible trigger....
