Long-term effects of neonatal single or multiple isoflurane exposures on spatial memory in rats

open access: yesFrontiers in Neurology, 2013
General anesthetics are neurotoxic to neonatal rodents and nonhuman primates. Neonatal exposure to general anesthetics has been associated with long-term cognitive deficits in animal models. Some data from humans are consistent with long-term deleterious

A mini-review of the effects of inhalational and intravenous anesthetics on oxidative stress in dogs

open access: yesFrontiers in Veterinary Science, 2022
General anesthesia increases the production of reactive oxygen species (ROS), which can exacerbate or increase oxidative stress and thus affect the prognosis of surgical procedures.

High-throughput screening in larval zebrafish identifies novel potent sedative-hypnotics [PDF]

open access: yes, 2018
BACKGROUND: Many general anesthetics were discovered empirically, but primary screens to find new sedative-hypnotics in drug libraries have not used animals, limiting the types of drugs discovered.

General anesthetic action profile on the human prefrontal cortex cells through comprehensive single-cell RNA-seq analysis

open access: yesiScience, 2023
Summary: The cellular and molecular actions of general anesthetics to induce anesthesia state and also cellular signaling changes for subsequent potential “long term” effects remain largely elusive.

Phase transitions in biological membranes

open access: yes, 2018
Native membranes of biological cells display melting transitions of their lipids at a temperature of 10-20 degrees below body temperature. Such transitions can be observed in various bacterial cells, in nerves, in cancer cells, but also in lung ...

General Anesthetics: Aspects of Chirality, Pharmacodynamics, and Pharmacokinetics

open access: yesPharmaceuticals
The introduction of general anesthetics in the mid-19th century is considered one of the greatest contributions to medical practice. It was the first time that complicated surgical interventions became feasible, without putting an excessive strain on the

Anesthesia-induced developmental neurodegeneration: the role of neuronal organelles

open access: yesFrontiers in Neurology, 2012
Exposure to general anesthetics and antiepileptics during critical stages of brain development causes significant neurotoxicity to immature neurons.

Parosmia and dysgeusia after intravenous propofol-based general anesthesia: A case report

open access: yesAnnals of Cardiac Anaesthesia, 2022
Various drugs, including anesthetic agents, can cause parosmia in the perioperative period. There are reported cases of patients with alterations of smell and taste due to local anesthetics, nerve damage, or as a side effect of general anesthesia.

The free energy of biomembrane and nerve excitation and the role of anesthetics

open access: yes, 2018
In the electromechanical theory of nerve stimulation, the nerve impulse consists of a traveling region of solid membrane in a liquid environment. Therefore, the free energy necessary to stimulate a pulse is directly related to the free energy difference ...

Electrostatic Contributions of Aromatic Residues in the Local Anesthetic Receptor of Voltage-Gated Sodium Channels [PDF]

open access: yes, 2008
Antiarrhythmics, anticonvulsants, and local anesthetics target voltage-gated sodium channels, decreasing excitability of nerve and muscle cells. Channel inhibition by members of this family of cationic, hydrophobic drugs relies on the presence of highly ...
