    Greenaway RS
    2000/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    We provide experimental results from the scattering of light by deformed liquid droplets and droplets with inclusions. The characterization of droplet deformation could lead to improved measurement of droplet size as measured by commercial aerodynamic particle-sizing instruments. The characterization of droplets with inclusions can be of importance ...

    Characterization of Firefighter Exposures During Fire Overhaul
    Bolstad-Johnson DM ;
    Burgess JL
    2000/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    Previous studies have characterized firefighter exposures during fire suppression. However, minimal information is available regarding firefighter exposures during overhaul, when firefighters look for hidden fire inside attics, ceilings, and walls, often without respiratory protection. A comprehensive air monitoring study was conducted to character ...

    Lead and Cancer in Humans: Where Are We Now?
    Boffetta P ;
    Steenland, Kyle
    2000/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    Lead is only weakly mutagenic, but in vitro it inhibits DNA repair and acts synergistically with other mutagens. Lead acetate administered orally, cutaneously, or intraperitoneally causes kidney cancer, brain cancer (gliomas), and lung cancer in rodents, and acts synergistically with other carcinogens. Most cytogenetic studies of exposed workers ha ...

    Occupational Hazards in Female Ballet Dancers. Advocate for a Forgotten Population
    Kelman BB
    2000/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    1. Personal, economical, psychological, and physical factors increase a ballet dancer's stress, which can result in a higher risk for injuries. 2. Ballet dancers experience injuries to the foot, ankle, knee, hip, or back. The constant fear of injuries is universal among dancers because injuries can lead to permanent disability and the end of their ...

    Bray I
    2000/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    Traditional methods of adjustment for multiple comparisons (e.g., Bonferroni adjustments) have fallen into disuse in epidemiological studies. However, alternative kinds of adjustment for data with multiple comparisons may sometimes be advisable. When a large number of comparisons are made, and when there is a high cost to investigating false positi ...

    2000/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    Reactive gliosis is the most prominent response to diverse forms of central nervous system (CNS) injury. The signaling events that mediate this characteristic response to neural injury are under intense investigation. Several studies have demonstrated the activation of phosphoproteins within the mitogen-activated protein kinase (MAPK) and Janus kin ...

    With the goal of incorporating measures of sperm nuclear integrity in an epidemiology study, semen samples from young Czech men were analysed for sperm aneuploidy and sperm chromatin structure in addition to routine measures of sperm production and quality. The exposure in question was to high seasonal air pollution containing reactive polyaromatic ...

    2000/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    Enhanced expression of glial fibrillary acidic protein (GFAP) is known to be associated with toxicant-induced gliosis, a homotypic response of the central nervous system to neural injury. A variety of neurochemical and neurophysiological effects have been observed in experimental animals exposed to white spirit, but a linkage of such effects to neu ...

    This study replicated the factor model for the Reduced Laffrey Health Conception Scale (RLHCS), which was originally developed by Laffrey (1986) and reduced by Lusk, Kerr, and Baer (1995). Two independent samples of construction workers (n = 697 and n = 510) were used. The samples were predominately Caucasian males (over 97%), with mean ages of 35 ...

    In experimental studies of stress, restraint of laboratory rodents, perceived as easy to apply and believed to be reproducible, is a commonly used manipulation. The restraint manipulation is utilized as a technique to characterize the physiological, cellular and molecular consequences of stress as well as a tool to understand the ways in which stre ...

    Occupational health nurses play a vital role in addressing ergonomic problems in the workplace. Describing and documenting exposure to ergonomic risk factors is a relatively straightforward process in jobs in which the work is repetitive. In other types of work, the analysis becomes much more challenging because tasks may be repeated infrequently, ...
