Mineral-fluid interaction in the lungs: insights from reaction-path modeling
…from previous work described in the literature. Modeling of reaction paths in both closed and open systems confirms previous suggestions that chrysotile dissolves faster than tremolite in lung fluid, which offers an explanation for the apparent…

Change of heme oxygenase-1 expression in lung injury induced by chrysotile asbestos in vivo and in vitro
…and 6 mo of recovery time. The expression of HO-1 was observed by Western blot analysis, reverse-transcription polymerase chain reaction, and immunostaining. Protein levels of HO-1 increased at from 3 days to 6…

Calcitonin gene-related peptide (CGRP) as hazard marker for lung injury induced by dusts
…fibrosis were present in those exposed to SiCW and PT-1. The expression of CGRP in rat lung was observed by reverse-transcription polymerase chain reaction (RT-PCR) and enzyme immunometric assay (EIA). In RT-PCR…

Comparison of Calidria chrysotile asbestos to pure tremolite: final results of the inhalation biopersistence and histopathology examination following short-term exposure
…L > 20 microm), histopathological examination revealed no evidence of any inflammatory reaction either after the cessation of the last exposure or at any time during the subsequent 12-mo period. This is in marked contrast…

Role of Iron in the Cellular Effects of Asbestos
…investigations. Asbestos catalyzes many of the same reactions that iron does, including lipid peroxidation and DNA damage. At physiological pH, mobilization of iron from the fibers by a low-molecular-weight chelator greatly enhances these reactions…
