- There is developing interest in the potential association between anesthesia and the onset and progression of Alzheimer's disease. Several anesthetics have, thus, been demonstrated to induce tau hyperphosphorylation, an effect mostly mediated by anesthesia-induced hypothermia. Here, we tested the hy

- This is part of a continuing patch-clamp study exploring molecular actions of anesthetics and systematically varied related substances on 5-HT3A receptors as prototypes of ligand-gated ion channels. Specifically, n-alkanols, related to but simpler in structure than propofol, were studied to explore

- We recently developed ultra-sensitive ethanol receptors (USERs) as a novel tool for investigation of single receptor subunit populations sensitized to extremely low ethanol concentrations that do not affect other receptors in the nervous system. To this end, we found that mutations within the extrac
