Effect of combined actions of hip adduction/abduction on the force generation and maintenance of pelvic floor muscles in healthy women. [PDF]

PLoS ONE, 2017
Pelvic floor muscle (PFM) force and coordination are related to urinary incontinence severity and to sexual satisfaction. Health professionals frequently combine classic PFM exercises with hip adduction/abduction contraction to treat these disorders, but

Discrete 2D Material Programming for 3D Shaping and Morphogenesis‐Inspired 4D Bioprinting

Advanced Science, EarlyView.
Cell‐compatible discrete 2D material programming enables 2‐to‐3D shape transformation and morphogenesis‐inspired 4D bioprinting. By patterning cell‐supportive microdomains within a responsive hydrogel, the approach programs in‐plane growth to encode target metrics.

Effect of 1-acyl-5,6-dimethoxy / diethoxy-2-methylthiobenzimidazoles on APD90 and isometric contraction in guinea pig atrium and aortic preparations activated by carbachol and phenylephrine

Acta Medica Lituanica, 2010
Studies have shown that 1-acyl-5,6-diethoxy-2-methylthiobenzimidazole derivatives 3-pyridyl-(1); 2-pyridyl- (2); 4-thiazolyl- (3); 4-pyridyl- (4); methyl- (5); 2-thienyl- (6) and 1-acetyl-5,6-dimethoxy-2-methylthiobenzimidazole (7) exhibit positive ...

Why muscle is an efficient shock absorber. [PDF]

PLoS ONE, 2014
Skeletal muscles power body movement by converting free energy of ATP hydrolysis into mechanical work. During the landing phase of running or jumping some activated skeletal muscles are subjected to stretch.

Osseoperceptive EMG Feedback Improves Grasp Force Control in Myoelectric Prosthetic Hands

Advanced Science, EarlyView.
Osseoperception is explored as a non‐invasive pathway for delivering sensory feedback in myoelectric prosthetic control. By encoding the user's electromyographic (EMG) signal through bone‐conducted stimulation, this approach enables predictive grasp force regulation.

Impact of contraction intensity and ankle joint angle on calf muscle fascicle length and pennation angle during isometric and dynamic contractions

Scientific Reports
During muscle contraction, not only are the fascicles shortening but also the pennation angle changes, which leads to a faster contraction of the muscle than of its fascicles. This phenomenon is called muscle gearing, and it has a direct influence on the

Do differences in levels, types, and duration of muscle contraction have an effect on the degree of post-exercise depression?

Frontiers in Human Neuroscience, 2016
We conducted two experiments to determine how differences in muscle contraction levels, muscle contraction types, and movement duration affect degree of post-exercise depression (PED) after non-exhaustive, repetitive finger movement.

Space Jam‐Ming: Generating Interstitial Space Using Fragmented Granular GelMA to Investigate Novel Paradigms of Cancer Metastasis

Advanced Science, EarlyView.
Microgels enable independent control of stiffness and interstitial space, overcoming limitations of conventional 3D hydrogels. Using fragmented gelatin methacryloyl microgels, we show that stiffness does not restrict non‐metastatic breast cancer growth, contrary to bulk hydrogels, and reveal the role of adherent‐to‐suspension transition in cancer ...

Comments on the thermodynamical background to the growth and remodelling theory applied to a model of muscle fibre contraction

Applied and Computational Mechanics, 2010
Muscle fibre contraction is a complex thermomechanical process. The change in muscle fibre length (isotonic contraction) and tension (isometric contraction) may be regarded as muscle fibre growth (change in length) and remodelling (change in stiffness ...

Effect of Knee Angle, Contractile Activity, and Intensity of Force Production on Vastus Lateralis Stiffness: A Supersonic Shear Wave Elastography Pilot Study

Sports
Supersonic shear image (SSI) ultrasound elastography provides a quantitative assessment of tissue stiffness using the velocity of shear waves. SSI’s great potential has allowed researchers in fields like biomechanics and muscle physiology to study the ...
