Distribution of Nicotinic Receptors in the Human Brain: Quantitative Autoradiography Using 3H-Nicotine

, 1988
Several studies showed clearly that the mammalian central nervous system possess nicotinic receptors. Recently, using membrane receptor binding studies the regional distribution of 3H-nicotine and/or H-acetylcholine binding sites in the human brain has ...

Functional Analysis of Ligand‐Gated Chloride Channels in a Cnidarian Sheds Light on the Evolution of Inhibitory Signaling

Advanced Science, EarlyView.
We uncover a large variety of putative inhibitory ligand‐gated ion channels (LGICs) in the phylum Cnidaria, the sister group to all bilaterian animals. Phylogenetic analysis suggests a complex evolutionary history of inhibitory LGICs with diverse neurotransmitter ligands.

Cigarette Smoke‐Induced Alveolar Macrophage Senescence via GEM/SIRT3‐Mediated Mitochondrial Dysfunction

Advanced Science, EarlyView.
Cigarette smoke accelerates the aging of immune cells in the lung. By combining human single‐cell sequencing, cell culture, and mouse models, the authors show that the protein GEM drives mitochondrial damage and senescence in alveolar macrophages by suppressing SIRT3.

CD177 Deficiency Defines a Stable Subtype of Human Neutrophil Granulocytes with Tumor Promoting Activity

Advanced Science, EarlyView.
Human neutrophils exist as two epigenetically imprinted subtypes defined by stable CD177 expression or absence — a ratio that persists across time, circadian rhythms, and inflammation. CD177− neutrophils display a distinct molecular landscape enriched in arginase 1 and lipid metabolism markers, accumulate in head‐and‐neck tumors, and associate with ...

Glucagon‐Like Peptide‐1 Receptor Agonist Use in Obese Patients Is Associated With Decreased Risk of Revision and Retears After Arthroscopic Rotator Cuff Repair

Arthroscopy, EarlyView.
Purpose To evaluate the impact of preoperative glucagon‐like peptide‐1 receptor agonist (GLP‐1 RA) use on medical complications, emergency department use, and orthopaedic complications in obese patients undergoing arthroscopic rotator cuff repair. Methods Obese patients (defined by relevant ICD‐10 codes and confirmed by body mass index measurements ...

Nicotinic Receptor Antagonists as Treatments for Nicotine Abuse [PDF]

, 2014
Despite the proven efficacy of current pharmacotherapies for tobacco dependence, relapse rates continue to be high, indicating that novel medications are needed. Currently, several smoking cessation agents are available, including varenicline (Chantix®), bupropion (Zyban®), and cytisine (Tabex®).

Lynx1 Modulation of Nicotinic Acetylcholine Receptors [PDF]

, 2015
Nicotinic receptors are the target of nicotine in the brain. They are pentameric ion channels. The pentamer structure allows many combinations of receptors to be formed.

Dual Functions of Dietary Rubber Seed Oil Supplementation: Enriching N‐3 Polyunsaturated Fatty Acids and Enhancing Antioxidant Capacity in Pekin Ducks

Animal Research and One Health, EarlyView.
Dietary RSO supplementation improved growth performance, simultaneously enriched n‐3 polyunsaturated fatty acids (n‐3 PUFA), and enhanced antioxidant capacity in Pekin ducks, which suggested that RSO has the potential to be a novel n‐3 PUFA source and an antioxidant for Pekin ducks to generate animal functional foods.
