Cholesterol-induced suppression of Kir2 channels is mediated by decoupling at the inter-subunit interfaces
ISCIENCE, 25(5).
TL;DR:
It was found that increasing membrane cholesterol reduced the likelihood of contact between specific regions of the cytoplasmic and transmembrane domains of the channel, most prominently at the subunit-subunit interfaces of the cytosolic domains.

Predicting Inter-individual Variability During Lipid Resuscitation of Bupivacaine Cardiotoxicity in Rats: A Virtual Population Modeling Study
McDaniel, M., Flores, K. B., & Akpa, B. S. (2021, July 19). DRUGS IN R&D, Vol. 7.
MeSH headings : Anesthetics, Local / toxicity; Animals; Bupivacaine / toxicity; Cardiotoxicity; Lipids; Rats; Rats, Sprague-Dawley
TL;DR:
A mechanistic model predicted a plausible range of treatment outcomes that accurately predicts changes in LD50 when extrapolated to putatively toxic doses of bupivacaine, and causal analysis of the predicted survival outcomes indicated a critical synergy between scavenging and direct cardiotonic mechanisms of ILE action.

Oxygen and hydrogen isotopes in human hair and tap water: Modeling relationships in a modern Mexican population
Human Biology, 90(3), 197–211.
author keywords: delta H-2; delta O-18; MEXICO; TAP WATER; HAIR
TL;DR:
Data from this Mexican population did not exhibit the strong relationships between isotope values of 18O and 2H in tap water and hair that have been characteristic of other populations studied to date, and the results with parameters based on the American supermarket diet were disappointing.

BIOPHYSICAL JOURNAL, 115(7), 1264–1280.
Contributors: N. Barbera*, M. Ayee*, n & I. Levitan *
MeSH headings : Binding Sites; Cholesterol / metabolism; Elasticity; Ion Channel Gating; Molecular Dynamics Simulation; Potassium Channels, Inwardly Rectifying / chemistry; Potassium Channels, Inwardly Rectifying / metabolism; Protein Binding; Protein Conformation

Differential Effects of Sterols on Ion Channels: Stereospecific Binding vs Stereospecific Response
STEROL REGULATION OF ION CHANNELS, Vol. 80, pp. 25–50.
Contributors: N. Barbera*, M. Ayee*, n & I. Levitan *
MeSH headings : Cell Membrane / metabolism; Humans; Ion Channels / chemistry; Ion Channels / metabolism; Protein Binding; Stereoisomerism; Sterols / chemistry; Sterols / metabolism; Sterols / pharmacology; Substrate Specificity
TL;DR:
Accumulating evidence suggests that the structural requirements of ion channel cholesterol-binding sites are lax, allowing chiral isomers of cholesterol to bind to the same site in a nonstereospecific way, but the ability of a sterol to confer a functional effect on the channel activity can still be stereospespecific.
