Increased Bilateral Interactions in Middle-Aged Subjects [PDF]

, 2014
A hallmark of the age-related neural reorganization is that old versus young adults execute typical motor tasks by a more diffuse neural activation pattern including stronger ipsilateral activation during unilateral tasks.

Skeletal muscle optoacoustics reveals patterns of circulatory function and oxygen metabolism during exercise

Photoacoustics, 2023
Imaging skeletal muscle function and metabolism, as reported by local hemodynamics and oxygen kinetics, can elucidate muscle performance, severity of an underlying disease or outcome of a treatment.

The influence of contraction duration in muscle energy technique applied to the atlanto-axial joint [PDF]

, 2004
Background: Muscle Energy Technique (MET) has been advocated for the treatment of restricted range of motion in the upper neck. There is little evidence, however, to support the effectiveness of MET to increase motion in the cervical spine, or determine ...

Design and Analysis of Compression–Torsion Coupling Metamaterials Using the Golden Section Method

Advanced Engineering Materials, EarlyView.
A novel compression–torsion metamaterial is engineered using inclined rods and symmetry breaking. To optimize its torsional performance, the golden section method is employed. The mechanical response of the metamaterial is validated through both numerical analysis and experimental validation.

Cellular Responses to Mechanical Cues Across Scales: From Fundamental Insights to Translational Potential

Advanced Healthcare Materials, EarlyView.
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 ...

Neurally mediated renal vasoconstriction during isometric muscle contraction in cats [PDF]

, 1992
The aim of this study was to determine if the reflex increase in renal sympathetic nerve activity (RSNA) during static (isometric) muscle contraction evokes renal vasoconstriction and decreases renal blood flow.
