    Assessment of Dermal Sensitization by Nickel Salts in a Novel Humanized TLR-4 Mouse Model
    Aldinger, Jeffrey A. ;
    Anderson, Stacey E.
    2024/12/31 | National Institute for Occupational Safety and Health (NIOSH)
    The fundamental goal of this study was to determine the potential utility of a novel humanized Toll-like receptor-4 (hTLR-4) mouse model for future in vivo studies of nickel allergy. First, mice of both sexes and hTLR-4 expression profiles were incorporated into a Local Lymph Node Assay (LLNA) to assess skin sensitization. Next, a set of hTLR-4 hTL ...

    2024/12/27 | National Institute for Occupational Safety and Health (NIOSH)
    Diesel exhaust (DE) is an air pollutant containing gaseous compounds and particulate matter. Diesel engines are common on gas extraction and oil sites, leading to complex DE exposure to a broad range of compounds through occupational settings. The US EPA concluded that short-term exposure to DE leads to allergic inflammatory disorders of the airway ...

    2024/12/20 | National Institute for Occupational Safety and Health (NIOSH)
    Background Despite decreasing US consumption, over 90 million metric tons of coal were exported by the US in 2023, requiring significant infrastructure for transport, handling, and storage of coal at export terminals. Residents in Curtis Bay, Baltimore, Maryland, USA live at the fenceline of an open-air coal terminal and have, for decades, reported ...
  • PartialLinear SingleIndex Cox Regression Models with Multiple TimeDependent Covariates
    Partial-Linear Single-Index Cox Regression Models with Multiple Time-Dependent Covariates
    Crowley G ;
    Kwon S
    2024/12/20 | National Institute for Occupational Safety and Health (NIOSH)
    Background: In cohort studies with time-to-event outcomes, covariates of interest often have values that change over time. The classical Cox regression model can handle time-dependent covariates but assumes linear effects on the log hazard function, which can be limiting in practice. Furthermore, when multiple correlated covariates are studied, it ...
