Active mechanical threading by a molecular motor [PDF]

Angewandte Chemie International Edition, 2021
Abstract Molecular motors transform external energy input into directional motions and offer exquisite precision for nano‐scale manipulations. To make full use of molecular motor capacities, their directional motions need to be transmitted and used for powering downstream molecular events. Here we present a macrocyclic molecular motor

Relationship Between the Practice of Physical Activity and Physical Fitness in Physical Education Students: The Integrated Regulation As a Mediating Variable

Frontiers in Psychology, 2020
The practice of physical activity (PA) contributes to the prevention of chronic diseases such as obesity, metabolic syndrome or cardiovascular diseases, being also directly related to the individual’s physical fitness.

The relationship between physical activity, motor competence and health-related fitness in 14-year-old adolescents [PDF]

, 2008
Physical activity, physical fitness, and motor competence are important health-related constructs. However, the relationship between them, particularly among children and adolescents, is still unclear.

Acute Effects of Self-Correction on Spine Deviation and Balance in Adolescent Girls with Idiopathic Scoliosis

Sensors, 2022
Background: Adolescent idiopathic scoliosis (AIS) is a three-dimensional deformity of spine and trunk with a higher incidence in girls. AIS alters and reduces postural control and balance.

The neural correlates of speech motor sequence learning [PDF]

, 2015
Speech is perhaps the most sophisticated example of a species-wide movement capability in the animal kingdom, requiring split-second sequencing of approximately 100 muscles in the respiratory, laryngeal, and oral movement systems. Despite the unique role

Speed agility trends in children according to growth: A new approach to evaluate speed agility in children

Annals of Human Biology, 2021
Background Speed agility is considered as the whole assessment of speed of movement, agility and coordination. The 10x4m test has been broadly used to evaluate physical fitness and overall health in children of developmental ages.

Motor-Free Contractility in Active Gels [PDF]

Physical Review Letters, 2020
Animal cells form contractile structures to promote various functions, from cell motility to cell division. Force generation in these structures is often due to molecular motors such as myosin that require polar substrates for their function. Here, we propose a motor-free mechanism that can generate contraction in biopolymer networks without the need ...
