Influence of Repeated Exposure to Neonatal Isoflurane on Sleep Architecture and Neuronal Delta and Theta Oscillations in Adolescent Rats

by SmartTots | Feb 14, 2026 | Preclinical Articles, Research Articles

Abstract Background: Normal sleep architecture is important for brain development, and we previously demonstrated that a single exposure to isoflurane during the neonatal period did not induce changes in the sleep architecture and only minimally altered neuronal beta...

Editorial: Assessing Sleep: A New Biomarker for Developmental Anesthesia Neurotoxicity Research?

by SmartTots | Feb 14, 2026 | Preclinical Articles, Research Articles

This editorial responds to Armijo, et al citing that it is, at best, very difficult to compare functional outcome measures used in laboratory experiments with those applied to human studies. However, the editorial authors acknowledge that these recent laboratory...

Sevoflurane impairs neurogenesis and cognitive function by inhibiting fatty acid β-oxidation in neural stem/progenitor cells of neonatal rats

by SmartTots | Feb 14, 2026 | Preclinical Articles, Research Articles

Abstract Background: Sevoflurane impairs neurogenesis and cognitive function in the developing brain; however, the underlying mechanisms remain unclear. This study aimed to investigate the role of fatty acid β-oxidation (FAO) in neural stem/progenitor cells (NSPCs) as...

Integrated 3D human cerebral organoids and paediatric patient serum analysis reveals mechanisms and biomarkers of anaesthetic-induced neurotoxicity

by SmartTots | Feb 13, 2026 | Preclinical Articles, Research Articles

Abstract Background: General anaesthetics are essential for paediatric surgery but have been associated with neuronal injury and long-term cognitive deficits, thereby raising concerns over neurodevelopmental safety. However, the molecular mechanisms underlying...

Gut Microbiota Influences Developmental Anesthetic Neurotoxicity in Neonatal Rats

by SmartTots | Feb 13, 2026 | Preclinical Articles, Research Articles

Abstract Background: Anesthetic exposure during childhood is significantly associated with impairment of neurodevelopmental outcomes; however, the causal relationship and detailed mechanism of developmental anesthetic neurotoxicity remain unclear. Gut microbiota...

Somatostatin and its receptors involvement in sevoflurane-induced neurotoxicity: a narrative review

by SmartTots | Feb 13, 2026 | Preclinical Articles, Research Articles

Abstract As a widely used pediatric anesthetic, sevoflurane presents a paradoxical neurodevelopmental risk during vulnerable brain maturation periods. This review synthesizes emerging evidence on sevoflurane-induced developmental neurotoxicity, with a focus on...
