    2024/12/01 | National Institute for Occupational Safety and Health (NIOSH)
    Background: Crystalline silica particles are fibrogenic agents and established carcinogens, but the mechanisms for disease initiation and progression are not well understood. Previous studies demonstrate that the tumor suppressor gene, programmed cell death 4 (PDCD4), and its upstream regulator, microRNA 21 (miR-21), may be oncogenes for novel canc ...

    Program evaluations that lack experimental design often fail to produce evidence of impact because there is no available control group. Theory-based evaluations can generate evidence of a program's causal effects if evaluators collect evidence along the theorized causal chain and identify possible competing causes. However, few methods are availabl ...
