The aim was to determine the association between loss of muscle mass, loss of muscle strength, and physical ability in individuals with ID. Upper and lower extremity strength, muscle mass and muscle quality (MQ) were calculated. Physical ability was measured according to the Katz activities of daily living (ADL), stair climb test, and sit-to-stand test. We(More)
The human brain is probably the most complicated single structure in the biological universe. The cerebral cortex that is traditionally connected with consciousness is extremely complex. The brain contains approximately 1,000,000 km of nerve fibers, indicating its enormous complexity and which makes it difficult for scientists to reveal the function of the(More)

The aim of this study was to investigate the effect of physical training on balance, strength, and general well-being in adult people with intellectual disability (ID). This study evaluated how physical training can effect physical and psychological change among 'older' adults with mild ID. Participants consisted of non-randomly selected groups with ID(More)
A comparatively high incidence of ocular and orbital abnormalities has been reported in persons with Down syndrome. Eighty six children (50% male, 50% female) with Down syndrome in several institutions for individuals with learning difficulties (age range 5-18 years, mean 12.5) were examined for visual impairment in order to relate the ocular impairment to(More)
In this paper, restricted to describe the ontogenesis of the cell, we discuss the processing of DNA through RNA to proteins and argue that this process is not able to transfer the information necessary to organize the proteins in the cell, but only to transfer the information necessary to form the shape of the proteins. We shortly describe the structure of(More)
