The role of general anesthetics and the mechanisms of hippocampal and extra-hippocampal dysfunctions in the genesis of postoperative cognitive dysfunction

open access: yesNeural Regeneration Research, 2017
Postoperative cognitive dysfunction (POCD) is a multifactorial process with a huge number of predisposing, causal, and precipitating factors. In this scenario, the neuroinflammation and the microglial activation play a pivotal role by triggering and ...

The Role of Neuroactive Steroids in Analgesia and Anesthesia: An Interesting Comeback?

open access: yesBiomolecules, 2023
Published evidence over the past few decades suggests that general anesthetics could be neurotoxins especially when administered at the extremes of age.

Effects of gabergic phenols on the dynamic and structure of lipid bilayers: A molecular dynamic simulation approach [PDF]

open access: yes, 2019
γ-Aminobutyric acid (GABA) is the major inhibitory neurotransmitter in the vertebrate and invertebrate nervous system. GABAA receptors are activated by GABA and their agonists, and modulated by a wide variety of recognized drugs, including barbiturates ...

General anesthetics inhibit LPS-induced IL-1β expression in glial cells. [PDF]

open access: yesPLoS ONE, 2013
BACKGROUND: Glial cells, including microglia and astrocytes, are considered the primary source of proinflammatory cytokines in the brain. Immune insults stimulate glial cells to secrete proinflammatory cytokines that modulate the acute systemic response,

Propofol inhibits prokaryotic voltage-gated Na+ channels by promoting activation-coupled inactivation [PDF]

open access: yes, 2018
Propofol is widely used in the clinic for the induction and maintenance of general anesthesia. As with most general anesthetics, however, our understanding of its mechanism of action remains incomplete.

Monosynaptic Functional Connectivity in Cerebral Cortex During Wakefulness and Under Graded Levels of Anesthesia [PDF]

open access: yes, 2012
The balance between excitation and inhibition is considered to be of significant importance for neural computation and cognitive function. Excitatory and inhibitory functional connectivity in intact cortical neuronal networks in wakefulness and graded ...

Ropivacaine vs tetracaine in topical anesthesia for intravitreal injection [PDF]

open access: yes, 2015
Aim: The object of the study was to evaluate the long term efficacy and safety of ropivacaine 0,5% vs tetracaine 0,5% for topical anesthesia in intravitreal injection of dexamethasone in patients with diabetic macular edema (DME) and anti-vascular ...

Cognitive dysfunction following desflurane versus sevoflurane general anesthesia in elderly patients: a randomized controlled trial. [PDF]

open access: yes, 2014
UnlabelledAs life expectancy increases, more patients ≥65 years undergo general anesthesia. Anesthetic agents may contribute to postoperative cognitive dysfunction, and incidence may differ with anesthetic agents or intraoperative anesthesia depth ...

Effects of general anesthetics on visceral pain transmission in the spinal cord

open access: yesMolecular Pain, 2008
Current evidence suggests an analgesic role for the spinal cord action of general anesthetics; however, the cellular population and intracellular mechanisms underlying anti-visceral pain by general anesthetics still remain unclear.
