Expression profiling of miRNAs in chrysotile-exposed lung epithelial cells

环境与职业医学
BackgroundChrysotile is widely used in construction and industry. Research has shown that it is associated with lung fibrosis in occupational groups, but the involvement of microRNAs (miRNAs) in chrysotile-induced lung fibrosis has been less well studied,

Multiple plasmon resonances in naturally-occurring multiwall nanotubes: infrared spectra of chrysotile asbestos

, 2002
Chrysotile asbestos is formed by densely packed bundles of multiwall hollow nanotubes. Each wall in the nanotubes is a cylindrically wrapped layer of $Mg_3 Si_2 O_5 (OH)_4$.

The sub‐μm petrography of the observed meteorite fall Winchcombe—A complex array of pristine and altered chondrite components

Meteoritics &Planetary Science, Volume 60, Issue 9, Page 2149-2165, September 2025.
Abstract Samples of observed meteorite falls provide important constraints on alteration histories of Solar System materials. Due to its rapid collection, terrestrial alteration in the observed Mighei‐type (CM) carbonaceous chondrite fall Winchcombe was minimal.

Multi-Analytical Approach for Identifying Asbestos Minerals In Situ

Geosciences, 2018
An innovative and, as yet, untested approach is to analyze serpentinite and metabasite rocks containing asbestos using a portable multi-analytical device, which combines portable digital microscopy (p-DM), portable X-ray Fluorescence (p-XRF) and portable

Asuka 12236 more primitive than Paris: Clues given by their Infrared and Raman micro‐spectroscopy signatures

Meteoritics &Planetary Science, Volume 60, Issue 8, Page 1851-1860, August 2025.
Abstract Carbonaceous chondrites are meteorites originating from undifferentiated objects of the Solar System, which may retain signatures of primitive matter. Here, we present a comparative study between two CM chondrites Asuka 12236 and Paris, both considered among the most primitive in the carbonaceous chondrite meteorite collection.

Induction of IL-17 production from human peripheral blood CD4+ cells by asbestos exposure [PDF]

, 2017
We have previously reported that chronic, recurrent and low-dose exposure to asbestos fibers causes a reduction in antitumor immunity. Investigation of natural killer (NK) cells using an in vitro cell line model and comprising in vitro activation using ...

Seismic Velocities of Subducted Serpentinites Through the Lizardite‐Antigorite Transition

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract The mineralogical transition (lizardite to antigorite) occurring in serpentinites dragged down in subduction zones depends on the metamorphic pressure and temperature conditions. The seismic Vp/Vs ratio is useful for distinguishing serpentinites from other mantle rocks. To understand the effects of the metamorphic conditions and the associated
