    Mekala, Venugopalareddy
    2026/12/16 | National Institute for Occupational Safety and Health (NIOSH)
    Patients with lung squamous cell carcinoma (LUSC) are often diagnosed at advanced stages, limiting opportunities for early intervention. LUSC develops through multistep progression from low-grade lesions to high-grade lesions, including carcinoma in situ (CIS), of which about half progress to invasive cancer while the other half regress. Although f ...

    Mecchia, Marco ;
    Mattenklott, Markus
    2026/03/01 | National Institute for Occupational Safety and Health (NIOSH)
    The quantification of crystalline silica (quartz) in materials helps communicate the potential risk of exposure when the materials are then included in a work process that could generate an aerosol of particulate. Although many analytical laboratories have developed procedures for quantification of quartz in bulk samples, these procedures are not s ...
