The Department of Health and Human Services, specifically the Centers for Disease Control and Prevention (CDC), is seeking a vendor for a sole-source contract to evaluate test samples from rats exposed to silica-containing engineered stone dusts. The primary objective is to collaborate with the vendor to develop predictive algorithms for pre-symptomatic pulmonary fibrosis, utilizing their proprietary algorithms to assess the effectiveness of existing predictive models for radiation-induced pulmonary fibrosis in the context of silica-induced fibrosis. This initiative is critical for advancing research in pulmonary health and understanding the impacts of silica exposure, with the vendor responsible for miRNA extraction, sequencing, and bioinformatic analysis of the samples. Interested parties can contact Kathryn Green at ezj7@cdc.gov or by phone at 404-639-6470 for further details.
