Noradrenergic and cholinergic innervation of the normal human heart and changes associated with cardiomyopathy

open access: yesThe Anatomical Record, EarlyView.
Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.

Acetylcholine Attenuates Hydrogen Peroxide-Induced Intracellular Calcium Dyshomeostasis Through Both Muscarinic and Nicotinic Receptors in Cardiomyocytes

open access: yesCellular Physiology and Biochemistry, 2016
Background/Aims: Oxidative stress induced intracellular Ca2+ overload plays an important role in the pathophysiology of several heart diseases. Acetylcholine (ACh) has been shown to suppress reactive oxygen species generation during oxidative stress ...

Overview of Encapsulated Lysine and Methionine and Their Impacts on Transition Cow Performance and Health

open access: yesAnimal Research and One Health, EarlyView.
The transition period in dairy cows, spanning 3 weeks before and after calving, is a critical phase characterized by increased nutrient demands, reduced dry matter intake (DMI), and elevated risk of metabolic disorders such as negative nutrient balance (NNB), lipolysis, proteolysis, and oxidative stress.

Muscarinic receptor signaling in the pathophysiology of asthma and COPD

open access: yesRespiratory Research, 2006
Anticholinergics are widely used for the treatment of COPD, and to a lesser extent for asthma. Primarily used as bronchodilators, they reverse the action of vagally derived acetylcholine on airway smooth muscle contraction.

Mutations in M2 alter the selectivity of the mouse nicotinic acetylcholine receptor for organic and alkali metal cations [PDF]

open access: yes, 1992
We measured the permeability ratios (PX/PNa) of 3 wild-type, 1 hybrid, 2 subunit-deficient, and 22 mutant nicotinic receptors expressed in Xenopus oocytes for alkali metal and organic cations using shifts in the bi-ionic reversal potential of the ...

Elevated Hippocampal Cholinergic Neurostimulating Peptide precursor protein (HCNP-pp) mRNA in the amygdala in major depression [PDF]

open access: yes, 2015
The amygdala is innervated by the cholinergic system and is involved in major depressive disorder (MDD). Evidence suggests a hyper-activate cholinergic system in MDD.

Fusion Pores as Regulators of Quantal Size and Cellular Physiology

open access: yesBioEssays, EarlyView.
During regulated exocytosis, membrane fusion regulatory factors act directly on SNAREs and membrane lipids to control fusion pore dynamics. This, in turn, leads to a differential amount of cargo release (referred to in this article as “quantal size”) across various cell types, thereby triggering distinct physiological cues.

Severe drug-induced repetitive behaviors and striatal overexpression of VAChT in ChAT-ChR2-EYFP BAC transgenic mice

open access: yesFrontiers in Neural Circuits, 2014
In drug users, drug-related cues alone can induce dopamine release in the dorsal striatum. Instructive cues activate inputs to the striatum from both dopaminergic and cholinergic neurons, which are thought to work together to support motor learning and ...

Chemical Characterization, Antioxidant, and Anticholinesterase Activities of Libidibia ferrea (Mart. Ex Tul.) L.P.Queiroz and In Silico Studies with the Acetylcholinesterase Enzyme

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Libidibia ferrea is used in many parts of Brazil for a variety of conditions, such as inflammation, respiratory disorders, muscle pain, and gastrointestinal problems. This study evaluated the chemistry and antioxidant and acetylcholinesterase (AChE) inhibitory activities of L. ferrea extracts. Hydroethanolic extracts of leaves (ELLF) and bark (
