Association of nicotinic acetylcholine receptors with central respiratory control in isolated brainstem-spinal cord preparation of neonatal rats

Biological Research, 2006
Nicotine exposure is a risk factor in several breathing disorders Nicotinic acetylcholine receptors (nAChRs) exist in the ventrolateral medulla, an important site for respiratory control.

Activation of endplate nicotinic acetylcholine receptors by agonists [PDF]

Biochemical Pharmacology, 2015
The interaction of a small molecule made in one cell with a large receptor made in another is the signature event of cell signaling. Understanding the structure and energy changes associated with agonist activation is important for engineering drugs, receptors and synapses.

Lower density of calretinin‐immunopositive neurons in the putamen of subjects with schizophrenia

Journal of Anatomy, Volume 246, Issue 4, Page 505-516, April 2025.
Recent neuroimaging and histological studies highlight the striatum as a key area involved in SCH, but the specific impairment of neuronal subtypes in subcortical structures is not fully understood. This study is the first detailed investigation of neuroanatomical changes in the putamen in SCH, specifically examining the density of calretinin ...

Rates and Equilibria for a Photoisomerizable Antagonist at the Acetylcholine Receptor of Electrophorus Electroplaques [PDF]

, 1985
Voltage-jump and light-flash experiments have been performed on isolated Electrophorus electroplaques exposed simultaneously to nicotinic agonists and to the photoisomerizable compound 2,2'-bis-[α-(trimethylammonium)methyl]-azobenzene (2BQ).

Test–retest reliability of Doppler ultrasound‐based leg blood flow assessments during exercise in patients with chronic obstructive pulmonary disease

Experimental Physiology, EarlyView.
Abstract Doppler ultrasound may be used to assess leg blood flow (Q̇leg${{\dot{Q}}_{{\mathrm{leg}}}}$), but the reliability of this method remains unexplored in patients with chronic obstructive pulmonary disease (COPD), where between‐subject variability may be larger than healthy due to peripheral vascular changes.

Prediabetic cardiomyopathy is attenuated by hypothalamic PVN oxytocin neuron activation

The Journal of Physiology, EarlyView.
Abstract figure legend A long‐term high‐fat, high‐fructose diet induces prediabetes with insulin resistance, hyperinsulinaemia, elevated triglycerides and metabolic‐associated steatotic liver disease (MASLD) in male rats. Animals developed prediabetic cardiomyopathy characterized by diastolic dysfunction, interstitial fibrosis and tachycardia ...

Ligand-dependent opening of the multiple AMPA receptor conductance states: a concerted model

, 2014
Modulation of the properties of AMPA receptors at the post-synaptic membrane is one of the main suggested mechanisms behind synaptic plasticity in the central nervous system of vertebrates.

Cannabinoid exposure during pregnancy: Cardiorespiratory effects and offspring outcomes

The Journal of Physiology, EarlyView.
Abstract figure legend Prenatal exposure to cannabinoids has been investigated across human and animal studies to understand its impact on physiological development. Evidence suggests that early‐life cannabinoid exposure influence multiple developmental processes, extending beyond neurodevelopmental outcomes to potentially affect placental function ...

Human‐derived cardiac‐neural microtissues reveal catecholaminergic polymorphic ventricular tachycardia is also a disease of the sympathetic neuron

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic diagram illustrating the proposed pathway in which regulatory defects might occur in sympathetic neurons derived from hiPSC in catecholaminergic polymorphic ventricular tachycardia (CPVT). Specifically, enhanced calcium transients appeared to derive from three sources: enhanced membrane excitability (due to loss of ...
