  • The Association of Prenatal Manganese Exposure with ProblemSolving Skills and Its Mediation by the Building Blocks of Executive Function
    The Association of Prenatal Manganese Exposure with Problem-Solving Skills and Its Mediation by the Building Blocks of Executive Function
    Bellinger, David C. ;
    Coull, Brent A.
    2022/08/20 | National Institute for Occupational Safety and Health (NIOSH)
    Background: Problem-solving skills build upon three core executive functions: inhibition, working memory, and cognitive flexibility. There is evidence of adverse associations of prenatal exposure to manganese (Mn) with core executive functions, but less is known about Mn associations with problem-solving or potential mediators of this association. ...

    The Development and Initial Validation of a New Working Time Scale for Full-Time Workers with Non-Standard Schedules
    Barnes-Farrell JL ;
    Cavallari JM
    2022/08/20 | National Institute for Occupational Safety and Health (NIOSH)
    Background: Working time characteristics have been used to link work schedule features to health impairment; however, extant working time exposure assessments are narrow in scope. Prominent working time frameworks suggest that a broad range of schedule features should be assessed to best capture non-standard schedules. The purpose of this study was ...

    2022/08/16 | National Institute for Occupational Safety and Health (NIOSH)
    Double difference tomographic inversion on measurements of travelling time and location are performed to analyze the velocity structure within rock mass in underground mining. Residuals of each iteration are estimated to evaluate the conversion of computation. Average wave propagation velocities in tabular areas are assessed to compare the velocity ...
  • Biological effects of inhaled crude oil VI Immunotoxicity
    Biological effects of inhaled crude oil. VI. Immunotoxicity.
    Anderson, Stacey E. ;
    Baur R
    2022/08/15 | National Institute for Occupational Safety and Health (NIOSH)
    Crude oil is an unrefined petroleum product that is a mixture of hydrocarbons and other organic material. Studies on the individual components of crude oil and crude oil exposure itself suggest it has immunomodulatory potential. As investigations of the immunotoxicity of crude oil focus mainly on ingestion and dermal exposure, the effects of whole- ...

    Lin, Gary X.
    2022/08/15 | Toxicol Appl Pharmacol 2022 Aug; 449:116137 | National Institute for Occupational Safety and Health (NIOSH)
    Workers in the oil and gas industry are at risk for exposure to a number of physical and chemical hazards at the workplace. Chemical hazard risks include inhalation of crude oil or its volatile components. While several studies have investigated the neurotoxic effects of volatile hydrocarbons, in general, there is a paucity of studies assessing the ...

    Sullivan K
    2022/08/12 | National Institute for Occupational Safety and Health (NIOSH)
    Gulf War Illness (GWI) is a chronic multi-symptom disorder affecting as many as 30% of veterans of the 1991 Gulf War. Over the past 30 years since the war ended, an increasing body of research has accumulated on the pathobiology of this disorder. Overall, most evidence is suggestive of in-theater neurotoxicant exposures as a major underlying cause ...

    Health and Suffering: Measuring and Managing Occupational Valley Fever in California
    Hunter SM
    2022/08/12 | National Institute for Occupational Safety and Health (NIOSH)
    This dissertation investigates "Valley fever" or Coccidioidomycosis as a social, particularly as an occupational health problem. Valley fever is, primarily, a respiratory infection caused by breathing in tiny spores of the coccidioides fungus, a native of California. Most people infected experience mild flu-like symptoms; however, for some disease ...

    2022/08/11 | National Institute for Occupational Safety and Health (NIOSH)
    Extraction of coal through mountaintop removal mining (MTR) alters many dimensions of the landscape. Explosive blasts, exposed rock, and coal washing have the potential to pollute air and water. Previous research suggests that infants born to mothers living in areas with MTR have a higher prevalence of birth defects. In this cross-sectional study, ...
