  • Controlling Chemical Hazards During the Application of Artificial Fingernails
    Controlling Chemical Hazards During the Application of Artificial Fingernails
    Estill, Cheryl F. ;
    Flesch, Jerome P.
    2001/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    Artificial fingernail products are made from many chemicals, but the main one in most of these products is ethyl methacrylate (EMA). In 1974, the U.S. Food and Drug Administration outlawed a similar chemical, methyl methacrylate (MMA), which is used in fingernail products. MMA was proven harmful to nail technicians and customers. However, both MMA ...

    Comparative Pulmonary Toxicity of 6 Abrasive Blasting Agents
    Barger M ;
    Battelli LA
    2001/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    Inhalation of silica dust is associated with pulmonary fibrosis. Therefore, substitute abrasive materials have been suggested for use in abrasive blasting operations. To date, toxicological evaluation of most substitute abrasives has been incomplete. Therefore, the objective of this study was to compare the pulmonary toxicity of a set of substitute ...

    Documentation of Hazards and Safety Perceptions for Mechanized Logging Operations in East Central Alabama
    Bordas RM ;
    Davis GA
    2001/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    The logging industry remains one of the most hazardous in the nation. Despite more stringent safety regulations and improvements in equipment safety features, the rate of logging fatalities has decreased at a much lower rate than the decrease in the rate of illnesses and injuries in the same occupation. The objective of this research was to identif ...

    On-the-Job-Injury in South Texas Middle School Children
    Cooper SP ;
    Kelder SH
    2001/05/01 | Grant Final Reports
    Data on the work experiences of children and early adolescents are scarce. Preliminary evidence suggests, however, that very young workers - especially poor, minority youth - may be at risk for adverse work-related effects, including on-the-job injuries. Pre-existing work-related data from 7,420 South Texas middle school students were analyzed acco ...
  • A Putative UbiquitinDependent Epidermal Mechanism for the Recognition and Elimination of Defective Spermatozoa in the Mammalian Epididymis
    A Putative, Ubiquitin-Dependent Epidermal Mechanism for the Recognition and Elimination of Defective Spermatozoa in the Mammalian Epididymis
    Dominko T ;
    Moreno R
    2001/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    The normal structure and function of sperm are prerequisites for successful fertilization and embryonic development, but little is known about how defective sperm are eliminated during mammalian spermatogenesis. Here, we describe a ubiquitin-dependent, sperm quality control mechanism that resides in the mammalian epididymis, the site of sperm matur ...
  • Genetic Basis for Susceptibility to NoiseInduced Hearing Loss in Mice
    Genetic Basis for Susceptibility to Noise-Induced Hearing Loss in Mice
    Cortopassi GA ;
    Davis, Rickie R.
    2001/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    The C57BL/6J (B6) and DBA/2J (D2) inbred strains of mice exhibit an age-related hearing loss (AHL) due to a recessive gene (Ahl) that maps to Chromosome 10. The Ahl gene is also implicated in the susceptibility to noise-induced hearing loss (NIHL). The B6 mice (Ahl/Ahl) are more susceptible to NIHL than the CBA/CaJ (CB) mice (+(Ahl)). The B6xD2.F(1 ...

    The threat of bioterrorism in the United States is increasing. Health professionals, especially "front-line" practitioners, must be able to recognize the potential for major impacts from a bioterrorism event. Although an effective attack could produce numbers of casualties equivalent to those resulting from a nuclear weapon, an unannounced attack w ...
