    2002/02/09 | National Institute for Occupational Safety and Health (NIOSH)
    Risk factors for tendon disorders of the hand may include the force level, rate of force application, number of repetitions, and hand posture. To better understand injury mechanisms and to develop effective preventive measures, it is important to understand how these external factors affect internal tendon loading. Static force models have been use ...

    2002/02/07 | National Institute for Occupational Safety and Health (NIOSH)
    Over the last twenty years, considerable evidence has accumulated to suggest that gliosis represents a homotypic reponse of astrocytes and microglia to all types of nervous system injury, including damage resulting from exposure to chemicals or chemical mixtures. The astrocytic component of this response, often referred to as "reactive" gliosis or ...
