Formation of 8-hydroxydeoxyguanosine by asbestos and man made mineral fibres
…were compared with chrysotile fibres for their capacity to hydroxylate 2-deoxyguanosine to 8-hydroxydeoxyguanosine, a reaction that is mediated by formation of hydroxyl radicals. All three fibres produced 8-hydroxydeoxyguanosine in the absence of H2O2…

The association of phagocytosed asbestos dust with lysosome enzymes
…staining combined with electron microscopy. It was found that the acid phosphatase reaction was confined to the lysosome series of organelles, but that not all of these structures gave a positive reaction. In dust-containing macrophages…

Chestnut bur-shaped aggregates of chrysotile particles enable inoculation of Escherichia coli cells with plasmid DNA
…and chrysotile particles was exposed to agar using stirring apparatus, which allowed a constant vertical reaction force to be applied to the surface of the gel. Fluorescence microscopy was then used to illustrate the adsorption of…

Effect of secondary phase formation on the carbonation of olivine
…reactors. Altering the reaction conditions changed the Mg-carbonate morphology. We propose that this corresponded to changes in the ability of the system to precipitate hydromagnesite or magnesite. During high-temperature reactions (200 degrees C), an…

Tenascin expression and distribution in pleural inflammatory and fibrotic diseases
…as a marker of active pleural involvement. For this purpose we analyzed 71 histological samples of inflammatory and fibrotic pleura from patients with asbestos-induced pleural reaction (n = 6), postcardiac injury syndrome (n = 6…

Chemical elimination of the harmful properties of asbestos from military facilities
…phosphoric acid. The process proved very effective when the phosphoric acid concentration was 30%, the temperature was 90°C and the reaction time 60min. Contrary to the common asbestos treatment method that consists of landfilling, the proposed…

Exposure to silicates and systemic autoimmune-related outcomes in rodents: a systematic review
…Chrysotile did not induce ANA, and erionite fibers did induce ANA. Crystalline silica produced a lupus-like reaction in autoimmune-prone mouse strains, but the evidence in healthy strains was less convincing. The authors rated 19…
