METHODS: Lung tissue fiber was analyzed for a case series of 10 RCF workers and a 20-year longitudinal chest radiograph study of 1323 workers was …
WebIn vitro, asbestos leads to endoplasmic reticulum (ER) stress and apoptosis of epithelial cells, processes important in the development of lung fibrosis in humans. 27 These processes have been demonstrated in vivo as well and are followed by the initiation of fibrosis. 28 View chapter Purchase book Molecular Basis of Pulmonary Disease WebAug 22, 2014 · Biopersistence is complex and requires in vivo testing and analysis. However durability, the chemical mimicking of the process of fibre dissolution using in vitro treatment, is closely related to biopersistence and more readily determined. Here, we describe an experimental process to determine the durability of four types of carbon …
WebAn inhalation biopersistence study was designed to include not only the chrysotile component of the joint compound alone but also the sanded particulate component, as real-life exposure to abraded wall board would result in concomitant exposure to both chrysotile fibers and joint compound particles.
