  • Deficiency in Plasma Membrane Calcium ATPase Isoform 2 Increases Susceptibility to NoiseInduced Hearing Loss in Mice
    Deficiency in Plasma Membrane Calcium ATPase Isoform 2 Increases Susceptibility to Noise-Induced Hearing Loss in Mice
    Davis R ;
    Erway L
    2002/02/01 | National Institute for Occupational Safety and Health (NIOSH)
    Susceptibility to noise-induced hearing loss (NIHL) is poorly understood at the genetic level. Mice homozygous for a null mutation in the plasma membrane Ca2+-ATPase isoform 2 (PMCA2) gene are deaf (Kozel et al., 1998). PMCA2 is expressed on outer hair cell stereocilia (Furuta et al., 1998). Fridberger et al. (1998) observed that the outer hair cel ...

  • Pathophysiological Tissue Changes Associated with Repetitive Movement A Review of the Evidence
    Pathophysiological Tissue Changes Associated with Repetitive Movement: A Review of the Evidence
    Barbe MF ;
    Barr AE
    2002/02/01 | National Institute for Occupational Safety and Health (NIOSH)
    Work-related musculoskeletal disorders (WMSDs) represent approximately one third of workers' compensation costs in US private industry, yet estimates of acceptable exposure levels for forceful and repetitive tasks are imprecise, in part, due to lack of measures of tissue injury in humans. In this review, the authors discuss the scope of upper-extre ...
  • Occupational Risk of Lyme Disease An Epidemiological Review
    Occupational Risk of Lyme Disease: An Epidemiological Review
    Piacentino JD ;
    Schwartz BS
    2002/02/01 | National Institute for Occupational Safety and Health (NIOSH)
    Lyme disease is the most common vector borne disease in the United States. Since the early 1980s, a large body of literature has evaluated the occupational risk of Lyme disease. The availability of a new vaccine to prevent Lyme disease makes it necessary for occupational health professionals to make decisions regarding the occupational risk of the ...
  • Technology for Remote Mine Seal Construction
    Technology for Remote Mine Seal Construction
    02/01/2002 | NIOSH
    Mine fires can be especially perilous because toxic products can quickly spread well beyond the fire zone thereby exposing all underground miners to dangerous and deadly conditions. This paper provides a review of the available materials and technology ...

  • Oxidative DNA Damage Is Associated with Intense Noise Exposure in the Rat
    Oxidative DNA Damage Is Associated with Intense Noise Exposure in the Rat
    Franks J ;
    Mathias P
    2002/02/01 | National Institute for Occupational Safety and Health (NIOSH)
    Increasing evidence suggests that noise-induced hearing loss may be reduced or prevented with antioxidant therapy. Biochemical markers of reactive oxygen species (ROS)-induced damage can help elucidate possible treatment timing constraints. This study examined the time course of ROS damage following a 2-h, broad-band noise exposure resulting in per ...
