objective: osteopontin (opn) has been proposed to play a role in bone resorption. with regard to bone and cementum/dentin structural and histological similarities, it was hy-pothesized that expression of this gene might be increased in resorptive lacunae during orthodontic tooth movement. materials and methods: fixed nickel-titanium closed coil springs (dentaurum ® ) capa-ble of delivering appr...

background: work related musculoskeletal disorders (msds) are considered the most common cause loss of work time, increased costs and human injuries. the aim of this study was to investigate the effect of planned exercise movements to reduce musculoskeletal disorders (msds) and burnout in the computer users. method: in this study, the effects of exercise movements using the software were review...

mirror movement is an interesting but often overlooked neurological soft sign;these movements are described as simultaneous contralateral, involuntary, identical movements that accompany voluntary movements. this neurologic problem is very rarely seen in children; in familial cases there is a positive history of these movements in parents, diminishing with time. here, we have presented the case...

Previous research has demonstrated that people's movements can become unintentionally coordinated during interpersonal interaction. The current study sought to uncover the degree to which visual and verbal (conversation) interaction constrains and organizes the rhythmic limb movements of coactors. Two experiments were conducted in which pairs of participants completed an interpersonal puzzle ta...

Quadrupeds exhibit versatile gait patterns (walk, trot, pace, bound, etc.) in response to locomotion speed [1, 2]. These locomotor patterns are generated via the coordination between limb movements, i.e., interlimb coordination. However, the interlimb coordination mechanism for the generation of such locomotor patterns requires further investigation because it has not been clarified thus far.

We can adapt movements to a novel dynamic environment (e.g., tool use, microgravity, and perturbation) by acquiring an internal model of the dynamics. Although multiple environments can be learned simultaneously if each environment is experienced with different limb movement kinematics, it is controversial as to whether multiple internal models for a particular movement can be learned and flexi...

Humans and animals trained on sequential reaction tasks show decreases in reaction time and increases in anticipatory movements even long after they have ceased to make errors. Humans show these changes even when they do not explicitly recognize that they performed a repeating sequence. We have developed a task which rats learn to perform error-free quickly, but in which they continue to show p...
