Intermittent low‐intensity contractions cause a dissociation between maximal motor unit firing rates and changes in torque and contractile speed

Experimental Physiology, EarlyView.
Abstract The purpose was to test: (1) whether the decline in maximal motor unit (MU) firing rate is an invariable response when maximal voluntary contraction (MVC) torque is reduced following a submaximal muscle fatiguing task; and (2) whether fatigue‐induced slowing of contractile speed and firing rate decline are co‐dependent. Ten participants (three

Ageing alters cysteine oxidation‐regulated redox signalling in skeletal muscle: Integrative omics and AI‐based structural predictions

Experimental Physiology, EarlyView.
Abstract Ageing is associated with loss of skeletal muscle mass and strength (sarcopenia) and disrupted redox homeostasis. Redox signalling is essential for muscle adaptation, yet the mechanisms by which ageing disrupts cysteine‐based regulation are poorly defined. The drivers of site‐specific reactivity and signalling specificity in aged muscle remain

Calpain inhibitor II disturbed the interaction between alpha-synuclein and calpain 1.

, 2015
Colocalization fluorescence signals of alpha-synuclein and calpain 1 on brain slices were examined with an Olympus confocal microscope using the 40× objective lens. (A) Confocal microscopy images of immunofluorescence staining for C-terminal fragments of

Protective effect of cannabinoid type 2 receptor agonist (JWH‐133) against hepatotoxicity induced by Prangos ferulacea Lindl. extract

Experimental Physiology, EarlyView.
Abstract This study investigated Prangos ferulacea (PF)‐induced hepatotoxicity, its potential association with endoplasmic reticulum (ER) stress and proinflammatory cytokines, and the effect of the cannabinoid type 2 receptor agonist JWH‐133. Rats (n = 37) were divided into four groups: control–sham group (CSG, n = 9), PF extract group (PG, n = 9), PF ...

Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

Intramuscular pathways of maladaptation in overtraining syndrome

The Journal of Physiology, EarlyView.
Abstract figure legend The transition from adaptive overreaching to maladaptive overtraining and mechanisms through which excessive training load can lead to performance decline. Four interconnected pathophysiological domains are highlighted: neural fatigue, involving both central and peripheral components such as altered sensory feedback and reflex ...

A calpain inhibitor protects against fractalkine production in lipopolysaccharide-treated endothelial cells

Kidney Research and Clinical Practice, 2017
Background: Fractalkine (CX3CL1) is a chemokine with a unique CX3C motif and is produced by endothelial cells stimulated with lipopolysaccharide (LPS), tumor necrosis factor (TNF)-α, interleukin (IL)-1, and interferon-γ.

The role of extracellular vesicles in cell–cell crosstalk in cardiotoxicity

The Journal of Physiology, EarlyView.
Abstract figure legend Administration of a pharmacological agent can result in off‐target cardiotoxicity which can be driven by cell–cell crosstalk between healthy and dysfunctional cardiac cells. Extracellular vesicles (EVs) are lipid bilayer structures that can move biological cargo between cells, facilitating cell–cell crosstalk.

Intracellular mechanosensation in intestinal smooth muscle: Piezo1 complexes amplify signalling beyond the surface

The Journal of Physiology, EarlyView.
Abstract figure legend Mechanosensation is not confined to the cell surface. In intestinal smooth muscle Piezo1 is predominantly intracellular (86%), where it forms a nanoscale (<40 nm) complex at the sarcoplasmic reticulum (SR)–plasma membrane junction. Within this sensor–amplifier–effector axis intra‐Piezo1 is the sensor that detects force at the SR,
