Behavior and Regional Cortical BOLD Signal Fluctuations Are Altered in Adult Rabbits After Neonatal Volatile Anesthetic Exposure

by SmartTots | Jan 10, 2021 | Research Articles

Abstract Neonatal and infant exposure to volatile anesthetics has been associated with long-term learning, memory, and behavioral deficits. Although early anesthesia exposure has been linked to a number of underlying structural abnormalities, functional changes...

Androgenic Modulation of the Chloride Transporter NKCC1 Contributes to Age-dependent Isoflurane Neurotoxicity in Male Rats

by SmartTots | Jan 10, 2021 | Research Articles

Abstract Background Cognitive deficits after perinatal anesthetic exposure are well established outcomes in animal models. This vulnerability is sex-dependent and associated with expression levels of the chloride transporters NKCC1 and KCC2. The hypothesis was that...

Neuroprotection of the Developing Brain by Dexmedetomidine Is Mediated by Attenuating Single Propofol-induced Hippocampal Apoptosis and Synaptic Plasticity Deficits

by SmartTots | Jan 10, 2021 | Research Articles

Abstract Dexmedetomidine (DEX) has neuroprotective effects and its efficacy was determined in propofol-treated pups. Postnatal day (P) 7 rats were exposed to propofol and DEX to investigate the induced apoptosis-related gene expression. Furthermore, synaptic...

Interval-dependent neurotoxicity after multiple ketamine injections in late postnatal mice

by SmartTots | Jan 10, 2021 | Research Articles

Abstract Purpose Measuring the neurotoxic effects of multiple anesthetic exposures during neurodevelopment is complex due to the numerous factors that can affect the outcome. While we recently discovered that the interval between multiple sevoflurane exposures can...

Effects of early postnatal sevoflurane exposure on oligodendrocyte maturation and myelination in cerebral white matter of the rat

by SmartTots | Jan 10, 2021 | Research Articles

Abstract General anaesthesia may impose significant neurocognitive risks on the developing brain. As brain injury in preterm neonates has a particular predilection for cerebral white matter, we aimed to evaluate the effects of sevoflurane on oligodendrocyte maturation...
