The Effect of Xenon on the Voltage‒Current Characteristics of Tethered Lipid Bilayers.
In this study, we describe the effect of the noble gas, xenon on the electrical properties of tethered lipid bilayer membranes, (tBLMs), including the effect of xenon on the activation energy for electrical conduction through the tBLM. Such studies benefit from the stability of a tethered membrane given the wide range of temperatures that are scanned and the time required for these measurements. The results indicate that xenon increases the activation energy for electrical conduction through bilayers and decreases the average pore size that dominates the electrical conductance of the lipid bilayers at low voltages. Xenon possesses a high affinity for lipid membranes and is a potent general anaesthetic. Its anaesthetic potency is possibly associated with its effects on proteins embedded in the lipid membranes.
期刊介绍：
The Journal of Membrane Biology is dedicated to publishing high-quality science related to membrane biology, biochemistry and biophysics. In particular, we welcome work that uses modern experimental or computational methods including but not limited to those with microscopy, diffraction, NMR, computer simulations, or biochemistry aimed at membrane associated or membrane embedded proteins or model membrane systems. These methods might be applied to study topics like membrane protein structure and function, membrane mediated or controlled signaling mechanisms, cell-cell communication via gap junctions, the behavior of proteins and lipids based on monolayer or bilayer systems, or genetic and regulatory mechanisms controlling membrane function.
Research articles, short communications and reviews are all welcome. We also encourage authors to consider publishing ''negative'' results where experiments or simulations were well performed, but resulted in unusual or unexpected outcomes without obvious explanations.
While we welcome connections to clinical studies, submissions that are primarily clinical in nature or that fail to make connections to the basic science issues of membrane structure, chemistry and function, are not appropriate for the journal. In a similar way, studies that are primarily descriptive and narratives of assays in a clinical or population study are best published in other journals. If you are not certain, it is entirely appropriate to write to us to inquire if your study is a good fit for the journal.
