  • Comparative Effects of ECigarette and Conventional Cigarette Smoke on In Vitro Bronchial Epithelial Cell Responses
    Comparative Effects of E-Cigarette and Conventional Cigarette Smoke on In Vitro Bronchial Epithelial Cell Responses
    Bailey KL ;
    Bauer CD
    2025/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    Because of cigarette smoking, chronic lung diseases are the third leading cause of death in the United States. Electronic cigarettes (e-cig) were originally marketed as harm reduction devices for cigarette smokers due to low success rates with traditional smoking cessation methods. While several studies show that cigarette smoke causes damage to th ...
  • The Only Way Is Up Active Knee Exoskeleton Reduces Muscular Effort in Quadriceps During Weighted Stair Ascent
    The Only Way Is Up: Active Knee Exoskeleton Reduces Muscular Effort in Quadriceps During Weighted Stair Ascent
    Boon VS ;
    Gabert L
    2025/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    Firefighters consistently rank stair ascent with gear, which can weigh over 35 kg, as their most demanding activity. Weighted stair climbing requires dynamic motions and large knee torques, which can cause exhaustion in the short term, and overuse injuries in the long term. An active knee exoskeleton could potentially alleviate the burden on the we ...

    Multiwalled Carbon Nanotubes Activate the NLRP3 Inflammasome-Dependent Pyroptosis in Macrophages
    Gu JK ;
    Lim CS
    2025/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    Macrophages are major innate immune cells for the clearance of inhaled nanoparticles but may undergo cell death upon phagocytosis of certain nanoparticles due to their resistance to lysosomal degradation and high toxicity to the cell. Here we investigated the pyroptotic effect of exposure to fibrogenic multiwalled carbon nanotubes (MWCNTs) on macro ...

    Allergic fungal rhinosinusitis diagnosis, management, associated conditions, pathophysiology, and future directions: summary of a multidisciplinary workshop.
    Azar A ;
    Cahill KN
    2025/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    Allergic fungal rhinosinusitis (AFRS) is a unique endotype of chronic rhinosinusitis with nasal polyps (CRSwNP). Despite high recurrence rates and often more severe presenting signs compared with other subtypes of CRSwNP, research dedicated to AFRS has been lacking. Diagnostic criteria are outdated, the mechanistic relationship of AFRS to other ass ...
