Surface interaction between chrysotile and solutions (dissolution and adsorption): systematic x-ray photoelectron spectroscopy studies
…demonstrate two rate-limiting steps for the reaction: Mg2+ diffusion and chemical reaction. In some components of the Krebs cycle and in dilute hydrochloric and in oxalic acids, the reaction is limited by the exchange of…

SV40-like DNA sequences in pleural mesothelioma, bronchopulmonary carcinoma, and non-malignant pulmonary diseases
…tumours, and 33 non-malignant samples) and 38 additional samples distant from tumours were studied for the occurrence of SV40-like DNA sequences by polymerase chain reaction (PCR) amplification followed by hybridization with specific probes. Sequences…

Quantification of short and long asbestos fibers to assess asbestos exposure: a review of fiber size toxicity
…per milliliter. Reviewed experiments found short fibers less active than long ones, though at high doses they could cause inflammation, lung fibrosis and pleural reactions. Reviewed human studies linked short, thin fibers with lung cancer, but…

Mechanisms of fiber-induced genotoxicity
…during phagocytosis. Secondary molecules that are more stable than ROS are probably involved in DNA damage. Oxidoreduction reactions originating from cells can induce mutations. Genotoxicity is also demonstrated by chromosomal damage associated with impaired mitosis, as…
