The MX-Helix of Muscle nAChR Subunits Regulates Receptor Assembly and Surface Trafficking. [PDF]

open access: yes, 2020
Nicotinic acetylcholine receptors (AChRs) are pentameric channels that mediate fast transmission at the neuromuscular junction (NMJ) and defects in receptor expression underlie neuromuscular disorders such as myasthenia gravis and congenital myasthenic ...

Dopamine D_2-receptor activation elicits akinesia, rigidity, catalepsy, and tremor in mice expressing hypersensitive 4 nicotinic receptors via a cholinergic-dependent mechanism [PDF]

open access: yes, 2010
Recent studies suggest that high-affinity neuronal nicotinic acetylcholine receptors (nAChRs) containing α4 and β2 subunits (α4β2*) functionally interact with G-protein-coupled dopamine (DA) D_2 receptors in basal ganglia.

Surface Interactions during the Removal of Emerging Contaminants by Hydrochar-Based Adsorbents

open access: yesMolecules, 2020
The aim of this work was to test activated carbons derived from hydrochars produced from sunflower stem, olive stone and walnut shells, as adsorbents for emerging contaminants in aqueous solution, namely fluoxetine and nicotinic acid.

The kynurenine pathway and the brain: challenges, controversies and promises [PDF]

open access: yes, 2017
Research on the neurobiology of the kynurenine pathway has suffered years of relative obscurity because tryptophan degradation, and its involvement in both physiology and major brain diseases, was viewed almost exclusively through the lens of the well ...

Synthesis and characterization of ZnO/β-cyclodextrin/nicotinic acid nanocomposite and its biological and environmental application

open access: yesGreen Processing and Synthesis, 2023
In the present work, the disk-shaped zinc oxide (ZnO) nanoparticles were synthesized and functionalized with β-cyclodextrin (β-CD) and nicotinic acid (vitamin B3) using the wet co-precipitation method.

Influence of nicotinic acid on metabolism of cholesterol and triglycerides in man1

open access: yesJournal of Lipid Research, 1981
The mechanisms for the hypolipidemic action of nicotinic acid were examined in 12 patients with hyperlipidemia. Most patients were studied in the hospital on a metabolic ward.

Advances on the biosynthesis of pyridine rings

open access: yesEngineering Microbiology, 2023
Numerous studies have investigated the biosynthesis of pyridine heterocycles derived from nicotinic acid. However, metabolic pathways generating pyridine heterocycles in nature remain uninvestigated.

Thiol-reactive analogues of galanthamine, codeine and morphine as potential probes to interrogate allosteric binding within nAChRs [PDF]

open access: yes, 2016
Alkaloids including galanthamine (1) and codeine (2) are reported to be positive allosteric modulators of nicotinic acetylcholine receptors (nAChRs) but the binding sites responsible for this activity are not known with certainty.

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

open access: yesFEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

The use of isotopic carbon in a study of the metabolism of anthanilic acid in Neurospora [PDF]

open access: yes, 1949
The finding by Tatum, Banner, and Beadle (l), that the tryptophanless Neurospora mutant strain 10575 accumulates anthranilic acid, which in turn can be utilized for growth of strain 40008, has provided evidence that anthranilic acid is a biochemical ...
