Maternal sevoflurane exposure induces neurotoxicity in offspring rats via the CB1R/CDK5/p-tau pathway.

by SmartTots | Feb 14, 2023 | Preclinical Articles, Research Articles

Abstract Sevoflurane is widely used for maternal anesthesia during pregnancy. Sevoflurane exposure of rats at mid-gestation can cause abnormal development of the central nervous system in their offspring. Sevoflurane is known to increase the expression of cannabinoid...

Mechanistic insight into sevoflurane-associated developmental neurotoxicity.

by SmartTots | Feb 14, 2023 | Preclinical Articles, Research Articles

Abstract With the development of technology, more infants receive general anesthesia for surgery, other interventions, or clinical examination at an early stage after birth. However, whether general anesthetics can affect the function and structure of the developing...

Inhibition of ERK/CREB signaling contributes to postoperative learning and memory dysfunction in neonatal rats.

by SmartTots | Feb 14, 2023 | Preclinical Articles, Research Articles

Abstract Exposure to surgery with anesthesia early in life may lead to abnormal behavior, learning, and memory in humans. Pre-clinical studies have suggested a critical role of glial cell-derived neurotrophic factor (GDNF) in these effects. We hypothesize that the...

Tandem mass tag-based quantitative proteomic analysis of effects of multiple sevoflurane exposures on the cerebral cortex of neonatal and adult mice.

by SmartTots | Feb 14, 2023 | Preclinical Articles, Research Articles

Abstract Introduction: Sevoflurane is the most commonly used general anesthetic in pediatric surgery, but it has the potential to be neurotoxic. Previous research found that long-term or multiple sevoflurane exposures could cause cognitive deficits in newborn mice but...

Calpain-TRPC6 signaling pathway contributes to propofol-induced developmental neurotoxicity in rats.

by SmartTots | Feb 14, 2023 | Preclinical Articles, Research Articles

Abstract Growing animal studies suggest a risk of neuronal damage following early childhood exposure to anesthesia and sedation drugs including propofol. Inhibition of transient receptor potential canonical 6 (TRPC6) degradation has been shown to protect neurons from...

Effects of cumulative duration of repeated anaesthesia exposure on foetal brain development in the ovine model.

by SmartTots | Feb 14, 2023 | Preclinical Articles, Research Articles

Abstract Objective: Anaesthesia is required in 0.4-1% of pregnant women, and prolonged and repeated exposures to anaesthesia may be required. It is unknown whether these exposures may result in foetal neurotoxicity in humans. As sheep have a gestation comparable to...
