Simulating Effects of Learning and Lesions with a Model of Intrinsic and Synaptically Gated Responses of Striatal Cholinergic Interneurons [PDF]

open access: yes, 2006
The giant cholinergic interneurons of the striatum are tonically active neurons (TANs) that respond with characteristic pauses to novel events and to appetitive and aversive conditioned stimuli.

Imposed expiratory resistance, dynamic hyperinflation and locomotor power and fatigue

open access: yesExperimental Physiology, EarlyView.
Abstract Expiratory flow limitation results in dynamic hyperinflation, dyspnoea and premature exercise intolerance. We aimed to measure whether expiratory resistance reduces locomotor power via limiting maximal voluntary motor activity, exacerbating muscle fatigue, or both.

Cardioprotection via vagus nerve stimulation preconditioning: Reducing ischaemia–reperfusion injury and arrhythmic risk

open access: yesExperimental Physiology, EarlyView.
Abstract Acute myocardial infarction is a leading cause of morbidity and mortality, with ischaemia–reperfusion (I/R) injury exacerbating myocardial damage. Vagus nerve stimulation (VNS) has been reported to exert cardioprotective effects, but its efficacy in preconditioning against I/R injury requires further investigation.

Ouabain‐induced hypertension in rats: Mechanisms, variability and translational implications

open access: yesExperimental Physiology, EarlyView.
Abstract Ouabain‐induced hypertension is a multifactorial and condition‐dependent phenomenon involving coordinated actions across vascular, renal and central nervous system pathways. At the vascular level, ouabain inhibits Na⁺/K⁺‐ATPase, particularly the α2‐isoform, leading to elevated intracellular Ca2⁺, enhanced vasoconstriction and structural ...

Isometric handgrip contraction increases tibialis anterior intrinsic motoneuron excitability in a dose‐dependent manner

open access: yesExperimental Physiology, EarlyView.
Abstract The contribution of persistent inward currents (PICs) to motoneuron firing in the lower limb typically increases after a remote handgrip contraction, believed to result from diffuse serotonergic input increases in spinal cord. We investigated whether handgrip contraction intensity, duration and/or impulse would affect PIC estimates in tibialis

Glial cells in the heart: Implications for their roles in health and disease

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic representation of cardiac autonomic ganglia within epicardial fat pads (posterior heart surface shown), containing vagal postganglionic neuron cell bodies, associated fibres, and glia. These ganglia receive cholinergic input from vagal preganglionic neurons and adrenergic input from sympathetic postganglionic neurons ...

Prediabetic cardiomyopathy is attenuated by hypothalamic PVN oxytocin neuron activation

open access: yesThe 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 ...

Inhibitory Effect of Lidocaine on Duodenal Peristalsis During Endoscopic Retrograde Cholangiopancreatography: A Multicenter, Randomized Controlled Trial (With Video)

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Conventional antispasmodics used during endoscopic retrograde cholangiopancreatography (ERCP), such as hyoscine butylbromide and glucagon, are often contraindicated in elderly patients with comorbidities. This trial aimed to assess the efficacy of lidocaine for inhibiting duodenal peristalsis during ERCP.

Calcium puffs are generic InsP3-activated elementary calcium signals and are downregulated by prolonged hormonal stimulation to inhibit cellular calcium responses [PDF]

open access: yes, 2001
Elementary Ca2+ signals, such as "Ca2+ puffs", which arise from the activation of inositol 1,4,5-trisphosphate receptors, are building blocks for local and global Ca2+ signalling.
