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…

Exploration of the role of heat activation in enhancing serpentine carbon sequestration reactions
…to an amorphous component that preferentially forms at higher temperatures. The aqueous carbonation reaction process was investigated for representative materials via in situ synchrotron X-ray diffraction. Magnesite was observed to form directly at 15 MPa…

Mesothelioma and environmental exposure
…Under the microscope, liver tissue was unchanged, and there was a foreign-body type granulomatous reaction with multinucleated giant cells. No signs of mesothelioma were seen in either the exposed or the control groups. The authors…

Spontaneous polymerisation on amphibole asbestos: relevance to asbestos removal
…solution of eugenol, a substance that can form a lignin-like polymer (a solid resembling a natural component of wood). After the reaction, the fibres appeared to be completely included in the polymer. In electron microscope…

Analysis of the biological and chemical reactivity of zeolite-based aluminosilicate fibers and particulates
…NR8383). Our objective was to quantitatively determine the biological response upon interaction of the test particulates/fibers with lung macrophages and to evaluate the efficacy of surface iron on the zeolites to promote the Fenton reaction…

Asbestos bodies: clues to the mechanism of asbestos toxicity?
…lung, ascorbate was oxidized to oxalate in the presence of H2O2, a reaction inhibited by the iron chelator deferoxamine. The author called this a novel mechanism that may contribute to the pathogenicity of asbestos fibers. Oxidation…

Gemcitabine-induced erysipeloid skin lesions in a patient with malignant mesothelioma
…gemcitabine-induced erysipeloid skin reaction was reported in a small number of patients with previous history of radiotherapy or lymphedema. We reported a male patient who developed erysipeloid skin reaction following gemcitabine treatment in the absence…

Early inflammatory response to asbestos exposure in rat and hamster lungs: role of inducible nitric oxide synthase
…inducible nitric oxide synthase (iNOS) plays a role in the development of asbestos-related pulmonary disorders. The pulmonary reactions of rats and hamsters upon exposure to asbestos fibers are well known to be disparate. In addition…
