Experimental studies on mouse slow and fast twitch muscles
, 2006 This thesis deals with physiological and mechanical properties of fast and slow twitch mouse muscles. It discusses isometric, concentric and eccentric contractions of mouse extensor digitorum longus ('EDL') and soleus ('SOL') muscles. This project primarily investigated the behaviors of muscles, to give better understanding and improved descriptions ...

Acta Physiologica, Volume 242, Issue 10, October 2026.ABSTRACT Aim Repeated heat exposure may promote adaptive remodeling or cumulative tissue burden depending on thermal dose, but its graded molecular and functional consequences during recovery remain unclear. We examined whether repeated moderate (39°C) and severe (41°C) whole‐body hyperthermia produce distinct skeletal muscle trajectories involving ...

A Biomimetic 3D Human Skeletal Muscle Microtissue for Modeling Biological and Functional Hallmarks of Aging. [PDF]
Small SciA biomimetic 3D human skeletal muscle microtissue platform is developed by integrating primary young and aged SkMCs with muscle‐derived dECM and 3D‐printed PCL anchors. Aged constructs recapitulate selected biological and functional hallmarks of skeletal muscle aging, including impaired myotube formation, mitochondrial alterations, calcium handling ...

Acta Physiologica, Volume 242, Issue 10, October 2026.ABSTRACT Aim We aimed to evaluate an innovative dose–response approach to assess the metaboreflex with control of intramuscular metabolic perturbation (concept of metaboreflex gain). We also investigated potential sex differences in the metaboreflex using this new approach.

Acta Physiologica, Volume 242, Issue 10, October 2026.ABSTRACT The cardiovascular response to acute exercise is mediated by the autonomic nervous system (ANS) control mechanisms that modulate vascular resistance to support blood pressure and ensure adequate blood flow to active muscles. These autonomic neurocirculatory control mechanisms include a feedforward mechanism, known as central command, and three

The FASEB Journal, Volume 40, Issue 18, 30 September 2026.Cardioprotective hormone relaxin‐2 showed relevant effects on rat skeletal muscle by altering proteins linked to muscle function, regeneration, differentiation, mitochondrial function, glucose metabolism, and structural integrity and organization. Specifically, relaxin‐2 reduced the expression of 95 proteins, increased 32, and elicited unique proteins ...

Advanced Healthcare Materials, Volume 15, Issue 35, 18 September 2026.This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...

Advanced Materials Technologies, Volume 11, Issue 17, 3 September 2026.We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...
