The impact of lateral ankle ligament injuries on ankle stability and talar cartilage stress: a finite element analysis of combined injury mechanisms [PDF]

open access: yesFrontiers in Bioengineering and Biotechnology
ObjectiveTo investigate the differential biomechanical effects of injuries to the superior and inferior fascicles of the anterior talofibular ligament (ATFL) and the calcaneofibular ligament (CFL) on ankle stability and talar cartilage stress, providing ...

The Structural Adaptations That Mediate Disuse-Induced Atrophy of Skeletal Muscle

open access: yesCells, 2023
The maintenance of skeletal muscle mass plays a fundamental role in health and issues associated with quality of life. Mechanical signals are one of the most potent regulators of muscle mass, with a decrease in mechanical loading leading to a decrease in

Curvature of gastrocnemius muscle fascicles as function of muscle–tendon complex length and contraction in humans

open access: yesPhysiological Reports, 2023
It has been shown that muscle fascicle curvature increases with increasing contraction level and decreasing muscle–tendon complex length. The analyses were done with limited examination windows concerning contraction level, muscle–tendon complex length ...

Ultrasonographic measurements of fascicle length overestimate adaptations in serial sarcomere number

open access: yesExperimental Physiology, 2023
Ultrasound‐derived measurements of muscle fascicle length (FL) are often used to infer increases (chronic stretch or training) or decreases (muscle disuse or aging) in serial sarcomere number (SSN).

Do triceps surae muscle dynamics govern non-uniform Achilles tendon deformations? [PDF]

open access: yesPeerJ, 2018
The human Achilles tendon (AT) consists of sub-tendons arising from the gastrocnemius and soleus muscles that exhibit non-uniform tissue displacements thought to facilitate some independent actuation.

Combined DTI Tractography and Functional MRI Study of the Language Connectome in Healthy Volunteers: Extensive Mapping of White Matter Fascicles and Cortical Activations. [PDF]

open access: yesPLoS ONE, 2016
Despite a better understanding of brain language organization into large-scale cortical networks, the underlying white matter (WM) connectivity is still not mastered.

Maximal fascicle shortening velocity measurements in human medial gastrocnemius muscle in vivo

open access: yesPhysiological Reports, 2023
This study evaluated the maximal fascicle shortening velocity under near‐no‐load conditions. In addition, we determined whether the rate of torque development during ballistic contraction was related to maximal fascicle shortening velocity. Under passive

Endoneural selective stimulating using wire-microelectrode arrays [PDF]

open access: yes, 1999
In acute experiments eight 5- to 24-wire-microelectrode arrays were inserted into the common peroneal nerve of the rat, to investigate whether the electrodes could selectively stimulate motor units of the extensor digitorum longus (EDL) muscle.

A ketogenic supplement improves white matter energy supply and processing speed in mild cognitive impairment

open access: yesAlzheimer’s & Dementia: Translational Research & Clinical Interventions, 2021
Introduction White matter (WM) energy supply is crucial for axonal function and myelin maintenance. An exogenous source of ketones, the brain's alternative fuel to glucose, bypasses the brain's glucose‐specific energy deficit and improves cognitive ...
