The Effects of the Interplay Between Motor and Brownian Forces on the Rheology of Active Gels [PDF]

open access: yesJ. Phys. Chem. B 2018, 122, 15, 4267-4277, 2022
Active gels perform key mechanical roles inside the cell, such as cell division, motion and force sensing. The unique mechanical properties required to perform such functions arise from the interactions between molecular motors and semi-flexible polymeric filaments.

Evolution of determinant factors of maximal sprinting and repeated sprint ability in women soccer players

open access: yesScientific Reports, 2022
The present study aimed to determine the influence of force–power–velocity, vertical and horizontal jumps, and repeated sprint ability on the sprinting performance of adult women soccer players.

Stochastic simulations of cargo transport by processive molecular motors [PDF]

open access: yesJ. Chem. Phys. 131:245107, 2009, 2009
We use stochastic computer simulations to study the transport of a spherical cargo particle along a microtubule-like track on a planar substrate by several kinesin-like processive motors. Our newly developed adhesive motor dynamics algorithm combines the numerical integration of a Langevin equation for the motion of a sphere with kinetic rules for the ...

Self-Reported Physical Fitness in Children and Adolescents with Obesity: A Cross-Sectional Analysis on the Level of Alignment with Multiple Adiposity Indexes

open access: yesChildren, 2021
Obesity has been associated with several alterations that could limit physical activity (PA) practice. In pediatrics, some studies have highlighted the importance of enjoyment as a motivation to begin and maintain adherence in PA.

Acute Effects of High-Intensity Aerobic Exercise on Motor Cortical Excitability and Inhibition in Sedentary Adults

open access: yesFrontiers in Psychology, 2022
Transcranial magnetic stimulation studies have demonstrated increased cortical facilitation and reduced inhibition following aerobic exercise, even when examining motor regions separate to the exercised muscle group.

Peeling and Sliding in Nucleosome Repositioning [PDF]

open access: yesPhys. Rev. Lett., 99, 058105, (2007), 2007
We investigate the mechanisms of histone sliding and detachment with a stochastic model that couples thermally-induced, passive histone sliding with active motor-driven histone unwrapping. Analysis of a passive loop or twist defect-mediated histone sliding mechanism shows that diffusional sliding is enhanced as larger portions of the DNA is peeled off ...

Variation in human 3D trunk shape and its functional implications in hominin evolution

open access: yesScientific Reports, 2022
This study investigates the contribution of external trunk morphology and posture to running performance in an evolutionary framework. It has been proposed that the evolution from primitive to derived features of torso shape involved changes from a ...

Responses of Withdrawal Interneurons to Serotonin Applications in Naïve and Learned Snails Are Different

open access: yesFrontiers in Cellular Neuroscience, 2017
Long-term changes in membrane potential after associative training were described previously in identified premotor interneurons for withdrawal of the terrestrial snail Helix.

Poor Motor Competence Affects Functional Capacities and Healthcare in Children and Adolescents with Obesity

open access: yesSports
Background: From a young age, children learn different motor skills known as fundamental motor skills. The acquisition of these skills is crucial for the future development of context-tailored actions that could improve adherence to physical activity (PA)

Self-Perceived Physical Level and Fitness Performance in Children and Adolescents with Inflammatory Bowel Disease

open access: yesChildren, 2022
Background: Inflammatory bowel disease (IBD) patients show a higher risk of developing metabolic and cardiovascular diseases due to the presence of systemic low-grade chronic inflammation.
