Chronic Nicotine Selectively Enhances α4β2* Nicotinic Acetylcholine Receptors in the Nigrostriatal Dopamine Pathway [PDF]
These electrophysiological experiments, in slices and intact animals, study the effects of in vivo chronic exposure to nicotine on functional α4β2* nAChRs in the nigrostriatal dopaminergic (DA) pathway.

ABSTRACT Medicago sativa L. (alfalfa) harbors a remarkably diverse reservoir of bioactive secondary metabolites. Flavonoids, isoflavones, and triterpenoid saponins dominate its bioactivity landscape, driving potent antioxidant, anti‐inflammatory, antimicrobial, estrogenic, hypolipidemic, and cytotoxic actions through redox modulation, membrane ...

Muscarinic cholinergic receptors in rabbit retina
Abstract Binding sites with high affinity and specificity for [3 H]-quinuclidinyl benzilate are present in rabbit retinal homogenates. Only one set of binding sites was detected with an apparent dissociation constant of 2.13 times 10−10 M and a density of 59.2 fmol mg−1 of protein.

Insect‐Derived Bioactives for Glycemic Control and Gut Health: A Review
Insect‐derived bioactive compounds (e.g., peptides, polysaccharides) effectively regulate blood glucose through dual mechanisms: directly inhibiting carbohydrate‐digesting enzymes and glucose transporters, and indirectly modulating gut microbiota to enhance intestinal barrier integrity.

In the freezing of gait in Parkinson's disease, white matter shows decreased local activity but increased functional connectivity. These distinct dysfunctions are uniquely associated with specific neurotransmitter systems (GABA, dopamine, etc.), mapping a new neurochemical basis for this debilitating symptom. ABSTRACT Freezing of gait (FOG) is a severe

This study shows that (a) the slopes of dose-response curves of bromoacetylcholine (BrACh) and acetylcoline (ACh) were the same; (b) the dose-response curves of BrACh to contract superfused chick biventer cervicis and frog rectus abdominis muscles were shifted to the right by d-tubocurarine in a parallel fashio; and (c) the responses of BrACh were not ...

ABSTRACT Severe refractory constipation can lead to fecal retention requiring hospitalization, nasogastric cleanout, or manual disimpaction, and in some cases, surgery. Neostigmine, a reversible acetylcholinesterase inhibitor, is commonly used for pseudo‐obstruction but rarely for refractory constipation. Here, we report a 21‐year‐old male with chronic

Selectively driving cholinergic fibers optically in the thalamic reticular nucleus promotes sleep
Cholinergic projections from the basal forebrain and brainstem are thought to play important roles in rapid eye movement (REM) sleep and arousal. Using transgenic mice in which channelrhdopsin-2 is selectively expressed in cholinergic neurons, we show ...
