COVID‐19 and myasthenia gravis: A review of neurological implications of the SARS‐COV‐2

Brain and Behavior, Volume 12, Issue 12, December 2022., 2022
Abstract Introduction This review highlights the potential mechanisms of neuromuscular manifestation of COVID‐19, especially myasthenia gravis (MG). Methods An extensive literature search was conducted by two independent investigators using PubMed/MEDLINE and Google Scholar from its inception to December 2020. Results Exacerbations of clinical symptoms

Functional activity of peptide ion channels in tethered bilayer lipid membranes: Review

Electrochemical Science Advances, Volume 2, Issue 6, December 2022., 2022
Abstract Ion transport across biomembranes plays a major role in living cells. This fundamental function is normally carried out by molecules with both a hydrophobic and a hydrophilic side (amphiphilic molecules), which aggregate within the membrane forming a hydrophilic pore (the ion channel) permitting the selective translocation of permeant ions ...

Using the Honey Bee (Apis mellifera L.) Cell Line AmE‐711 to Evaluate Insecticide Toxicity

Environmental Toxicology and Chemistry, Volume 42, Issue 1, Page 88-99, January 2023., 2023
Abstract One of the main contributors to poor productivity and elevated mortality of honey bee colonies globally is insecticide exposure. Whole‐organism and colony‐level studies have demonstrated the effects of insecticides on many aspects of honey bee biology and have also shown their interactions with pathogens.

Defining the Biologically Plausible Taxonomic Domain of Applicability of an Adverse Outcome Pathway: A Case Study Linking Nicotinic Acetylcholine Receptor Activation to Colony Death

Environmental Toxicology and Chemistry, Volume 42, Issue 1, Page 71-87, January 2023., 2023
Abstract For the majority of developed adverse outcome pathways (AOPs), the taxonomic domain of applicability (tDOA) is typically narrowly defined with a single or a handful of species. Defining the tDOA of an AOP is critical for use in regulatory decision‐making, particularly when considering protection of untested species.

Controversies in spine research: Organ culture versus in vivo models for studies of the intervertebral disc

JOR SPINE, Volume 5, Issue 4, December 2022., 2022
Abstract Intervertebral disc degeneration is a common cause of low back pain, the leading cause of disability worldwide. Appropriate preclinical models for intervertebral disc research are essential to achieving a better understanding of underlying pathophysiology and for the development, evaluation, and translation of more effective treatments.

Functional and structural markers of peripheral microvascular autonomic neuropathy

Muscle &Nerve, Volume 67, Issue 2, Page 146-153, February 2023., 2023
Abstract Introduction/Aims Autonomic dysfunction is a common complication of small‐fiber neuropathy (SFN). In this study we aimed to assess the applicability of autonomic microvascular indices as a potential marker for SFN assessment. Methods Fifteen patients with confirmed SFN (idiopathic neuropathy [n = 10], chemotherapy‐induced peripheral neuropathy

Spontaneous Lipid Binding to the Nicotinic Acetylcholine Receptor in a Native Membrane [PDF]

, 2021
The nicotinic acetylcholine receptor (nAChR) and other pentameric ligand-gated ion channels (pLGICs) are native to neuronal membranes with an unusual lipid composition. While it is well-established that these receptors can be significantly modulated by lipids, the underlying mechanisms have been primarily studied in model membranes with only a few ...

Toxic Effect of Cigarette Smoke on Brainstem Nicotinic Receptor Expression: Primary Cause of Sudden Unexplained Perinatal Death

Toxics, 2018
Among the neurotoxicants contained in tobacco smoke, if absorbed during pregnancy, nicotine significantly affects α7-nicotinic acetylcholine receptors, which play essential roles in the development of the brainstem regions receiving cholinergic ...

Activation of a nicotinic acetylcholine receptor

Biophysical Journal, 1984
We studied activation of the nicotinic acetylcholine (ACh) receptor on cells of a mouse clonal muscle cell line (BC3H1). We analyzed single-channel currents through outside-out patches elicited with various concentrations of acetylcholine (ACh), carbamylcholine (Carb) and suberyldicholine (Sub).

Proteomic profiling of impaired excitation–contraction coupling and abnormal calcium handling in muscular dystrophy

PROTEOMICS, Volume 22, Issue 23-24, December 2022., 2022
Abstract The X‐linked inherited neuromuscular disorder Duchenne muscular dystrophy is characterised by primary abnormalities in the membrane cytoskeletal component dystrophin. The almost complete absence of the Dp427‐M isoform of dystrophin in skeletal muscles renders contractile fibres more susceptible to progressive degeneration and a leaky ...
