From ab initio quantum mechanics to molecular neurobiology: A cation-pi binding site in the nicotinic receptor [PDF]

open access: yes, 1998
The nicotinic acetylcholine receptor is the prototype ligand-gated ion channel. A number of aromatic amino acids have been identified as contributing to the agonist binding site, suggesting that cation-pi interactions may be involved in binding the ...

Species composition of blow flies (Diptera: Calliphoridae) colonizing pig carcasses exposed to bifenthrin‐ and clothianidin‐containing products

open access: yesMedical and Veterinary Entomology, EarlyView.
High clothianidin concentrations prevented colonization, while bifenthrin showed a non‐significant trend of reduced fly abundance, indicating both insecticides may suppress blow fly activity on treated carcasses. Adult emergence rates were unaffected, with no statistically significant differences observed across insecticide treatments, suggesting ...

Effects of Electroacupuncture at ST36 on Visceral Pain and Inflammatory Markers in IBS Rats

open access: yesNeurogastroenterology &Motility, EarlyView.
Electroacupuncture (EA) at ST36 significantly reduced visceral pain and colonic inflammation in IBS model rats. EA increased pain thresholds, lowered AWR scores, and downregulated key inflammatory mediators (IL‐1β, IL‐6, TNF‐α, TRPV1, NF‐κB). These findings highlight ST36‐targeted EA as a promising therapeutic strategy for IBS visceral hypersensitivity

A novel anxiety-associated SNP identified in LYNX2 (LYPD1) is associated with decreased protein binding to nicotinic acetylcholine receptors

open access: yesFrontiers in Behavioral Neuroscience
IntroductionAnxiety disorders are among the most common mental illnesses in the US. An estimated 31.1% of U.S. adults experience any anxiety disorder at some time in their lives.

Microgravity‐induced changes in skeletal muscle and possible countermeasures: What we can learn from bed rest and human space studies

open access: yesExperimental Physiology, EarlyView.
Abstract Despite exercise countermeasures to sustain health and performance in spaceflight, complete maintenance of muscle mass and functions in microgravity is still not possible for most astronauts. The principal cause of the limited effectiveness of existing exercise countermeasures is the difficulty in achieving full loading forces in space.

Characterization of ibogaine analogs on the hα3β4 nicotinic acetylcholine receptor. [PDF]

open access: yes, 2012
Nicotine addiction is a global health problem that affects nearly one-third of the population. Animal models have shown that the beta-4 subunit of nicotinic acetylcholine receptors (nAChR) expressed in the habenulointerpeduncular pathway plays a ...

Human‐derived cardiac‐neural microtissues reveal catecholaminergic polymorphic ventricular tachycardia is also a disease of the sympathetic neuron

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic diagram illustrating the proposed pathway in which regulatory defects might occur in sympathetic neurons derived from hiPSC in catecholaminergic polymorphic ventricular tachycardia (CPVT). Specifically, enhanced calcium transients appeared to derive from three sources: enhanced membrane excitability (due to loss of ...

Stac2 genetic deletion alters mouse chromaffin cells’ CaV channel composition, increases membrane excitability and reduces vesicle exocytosis

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Stac2 adaptor protein is expressed in neurons and endocrine cells. Using a global Stac2 knockout mouse model here we investigated the role of endogenous Stac2 in adrenal gland mouse chromaffin cell (MCC) excitability and catecholamine vesicle exocytosis.

Ivermectin Toxicity in Humans and Animals: Clinical Spectrum, Mechanisms, and Management

open access: yesJournal of Applied Toxicology, Volume 46, Issue 6, Page 1856-1870, June 2026.
ABSTRACT Ivermectin is a widely used macrocyclic lactone with established efficacy against a broad range of parasitic infections in humans and animals and a long‐standing reputation for clinical safety. However, increasing evidence indicates that ivermectin can produce clinically relevant toxicity under specific conditions, particularly involving the ...
