Motivated by a biased diffusion of molecular motors with the bias dependent on the state of the substrate, we investigate a random walk on a one-dimensional lattice that contains weak links (called "bridges") which are affected by the walker. Namely, a bridge is destroyed with probability when p the walker crosses it; the walker is not allowed to cross it again and this leads to a directed moti...

Background: The aim of present study was to determine the influence of stress management on affective control and distress tolerance in mothers of children with sensory-motor disabilities. Methods: This current study was a study with pretest-posttest and treatment group. The thirty mothers of children with sensory-motor disabilities were selected from sensory-motor disabilities center in Qum...

We investigated the acquisition and integration of temporal and ordinal sequence information in an incidental learning model of motor skill acquisition (the serial reaction time task). Human participants were exposed to a stimulus-response sequence that had temporal structure, ordinal structure, or both. By changing the temporal or ordinal structure, or both, we were able to ask two questions: ...

OBJECTIVE The objective was to determine whether the School Version of the Assessment of Motor and Process Skills (School AMPS) is valid when used to evaluate students in different world regions. METHOD Participants were 984 students, ages 3-13 yr, from North America, Australia and New Zealand, United Kingdom, and the Nordic countries, matched for age and diagnoses. We used FACETS many-facete...

Introduction: Profilin1 (PFN1) is a ubiquitously expressed protein known for its function as a regulator of actin polymerization and dynamics. A recent discovery linked mutant PFN1 to Amyotrophic Lateral Sclerosis (ALS), which is a fatal and progressive motor neuron disease. We have also demonstrated that Gly118Val mutation in PFN1 is a cause of ALS, and the formation of aggregates containing m...
