    Ducatman A ;
    Li H
    2002/07/04 | National Institute for Occupational Safety and Health (NIOSH)
    We investigated factors associated with the use of respiratory protection and explored the effectiveness of respirators among coal miners. Between 1987 and 1992, respiratory symptoms, smoking, lung function, and dust exposures were assessed longitudinally among 185 underground bituminous coal miners. Self-reported use of respiratory protection was ...
  • A Random Walk Model of Stratum Corneum Diffusion 2002
    A Random Walk Model of Stratum Corneum Diffusion [2002]
    Frasch, H. Fredrick
    2002/07/04 | National Institute for Occupational Safety and Health (NIOSH)
    A mathematical model has been developed that is based on the molecular mechanism of diffusion and that explicitly incorporates the non-uniform structure of the stratum corneum. The model is used to predict permeability coefficients of chemicals based on their molecular weight (MW) and octanol-water partition coefficient (P). [Description provided b ...

    Mead BJ
    2002/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    Using non-powdered, low-protein natural rubber latex (NRL) gloves has been shown to reduce the elicitation of respiratory symptoms in latex-allergic individuals; however, the role of dermal exposure in the induction of sensitization is not completely understood. Objective: These studies were conducted to (1) determine levels of NRL protein in glove ...

    Low socioeconomic status is associated with high mortality, but the extent to which socioeconomic status affects particular diseases and whether socioeconomic status effects have changed over time are uncertain. The authors used education as a marker for socioeconomic status in a study of two large American Cancer Society cohorts (follow-up, 1959-1 ...

    2002/07/01 | National Institute for Occupational Safety and Health (NIOSH)
    Trimellitic anhydride (TMA)-induced occupational asthma is thought to be associated with its ability to acylate proteins and to induce production of TMA-specific immunoglobulin (Ig)E. Though the respiratory tract is considered to be a major exposure route leading to airway sensitization, the potential role of dermal exposure producing asthmatic sen ...
