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…

Rat model demonstrates a high risk of tremolite but a low risk of anthophyllite for mesothelial carcinogenesis
…In half of the animals, repeated intraperitoneal injections of nitrilotriacetate (NTA), an iron chelator to promote Fenton reaction, were performed to evaluate the potential involvement of iron overload. Tremolite induced MM with a high incidence (96…

Microbe-Mineral Interactions between Asbestos and Thermophilic Chemolithoautotrophic Anaerobes
…structure of the asbestos mineral fibers. Further constraints on the relationships between elemental release rates, amount of starting asbestos, reaction volumes, and incubation times will be required to better compare asbestos dissolution treatments studied to date.

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…

Additional proteins in BAL fluid of Metsovites environmentally exposed to asbestos: more evidence of "protection" against neoplasia?
…The two proteins were present in all Metsovites with PCs but in none without PCs and also in none of the control groups. This study further separates two groups of Metsovites with different reaction to asbestos…

Cytotoxicity induced by exposure to natural and synthetic tremolite asbestos: an in vitro pilot study
…the etiology of the pathological effects of asbestos, cellular reactions to natural and synthetic asbestos fibers were compared using a lung alveolar cancer cell line (A549 epithelial cells), considered the first target of inhaled micro-environmental…

Mantle wedge infiltrated with saline fluids from dehydration and decarbonation of subducting slab
…derived fluids play an important role in heat and material transfer in subduction zones. Dehydration and decarbonation reactions of minerals in the subducting slab have been investigated using phase equilibria and modeling of fluid flow. Nevertheless…
