Isometric training at longer muscle–tendon complex lengths: A potential countermeasure to impaired neuro‐muscle–tendon function during space travel

Experimental Physiology, EarlyView.
Abstract Manned space exploration to distant destinations, including Mars, continues to be an aspiration of humankind. Space travel does, however, present many challenges to the body, amongst which adaptation to microgravity is perhaps the largest. For instance, both short and long manned spaceflight missions have shown substantial deleterious effects ...

Improvement in muscle strength with low-load isotonic training depends on fascicle length but not joint angle [PDF]

Introduction: In this study we investigate whether low‐load isotonic training will elicit greater improvement in muscle strength at the same fascicle length, rather than at the same joint angle. Methods: Sixteen healthy men (24.1 ± 2.5 years of age) were

Changes in motor unit conduction velocity after unilateral lower‐limb suspension and active recovery are correlated with muscle ion channel gene expression

Experimental Physiology, EarlyView.
Abstract The effects of muscle disuse on the propagation of action potentials along motor unit (MU) muscle fibres, a key process for effective muscle activation and force generation, remain poorly understood. The aim of this study was to investigate changes in action potential propagation and to identify biological factors influencing these changes ...

Low‐threshold cutaneous mechanoreceptors on the foot sole have enhanced sensitivity when skin temperature is elevated

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic illustration of microneurography recordings used to examine the effects of local skin heating on cutaneous mechanoreceptor responses in the human foot (left panel). A microelectrode inserted into a peripheral nerve records single‐unit activity from tactile afferent fibres while controlled mechanical stimuli are applied ...

Cytoarchitecture and myeloarchitecture of the sheep auditory cortex

Journal of Anatomy, Volume 249, Issue 2, Page 233-246, August 2026.
This article describes the cyto‐ and myeloarchitecture of the sheep auditory cortex. It outlines a six‐layered cortical organization, with variations in cellular types and densities. The potential location of the primary auditory cortex is indicated by parvalbumin immunostaining.

MRI‐based, 3D analysis of Achilles tendon longitudinal strain under passive loading reveals limitations in conventional 2D measurement

Journal of Anatomy, Volume 249, Issue 2, Page 371-382, August 2026.
Graphical overview of 2D and 3D length measurements of the free Achilles tendon. The figure also illustrates how the typical distal morphology of the soleus muscle affects 2D measurement. Abstract Quantifying strain in the free Achilles tendon (ATF) is essential for understanding its mechanical function, yet existing in vivo studies report inconsistent

Serum Advanced Glycation End Products as Drivers of Poor Tendon Outcomes in Diabetes? An Emerging Hypothesis and Narrative Review

Endocrinology, Diabetes &Metabolism, Volume 9, Issue 4, July 2026.
Tendon injuries in diabetes heal poorly, with unclear drivers of extracellular matrix disruption and altered mechanics. This narrative review synthesizes in vitro, animal, and human studies, highlighting serum advanced glycation end products as potential systemic contributors.

Routine circumferential patellar denervation during total knee arthroplasty did not consistently eliminate neural structures at the lateral patellar border: A prospective randomised controlled trial with histological outcomes

Journal of Experimental Orthopaedics, Volume 13, Issue 3, July 2026.
Abstract Purpose Circumferential patellar denervation is widely performed during total knee arthroplasty under the assumption that electrocautery ablates nociceptive neural structures at the lateral patellar border. However, the microscopic effect of this procedure on neural substrates remains poorly defined.
