Therapy modifies cystine kidney stones at the macroscopic scale. Do such alterations exist at the mesoscopic and nanometre scale
TL;DR: Powder neutron diffraction analysis and/or scanning electron microscopy examination of cystine stones provide evidence that usual alkalinization by sodium bicarbonate associated with high diuresis significantly reduces the size of both nanocrystals and crystallites, while for other treatments, including alkalinizing drugs and thiol derivatives, the data suggest mainly changes in the topology of crystallites.
Physicochemical characterization of inorganic deposits associated with granulomas in cutaneous sarcoidosis.

TL;DR: It has been hypothesized that exogenous inorganic particles as crystalline silica could be a causal or adjuvant agent in sarcoidosis onset.

Arnaud Dessombz,Brahima Kirakoya,Gérard Coulibaly,Richard W. Ouedraogo,Lise Picaut,Raphael Weil,Dominique Bazin,Michel Daudon +7 more
TL;DR: For the first time, a dramatically high occurrence of a "scarce" urinary stone component, namely opaline silica, was reported in a series of consecutive calculi from a single country.

TL;DR: In this paper, a panel of complementary spectroscopic and diffraction tools were used to characterize 100 kidney stones obtained from the University Hospital of Ouagadougou (Burkina Faso).

Absence of Bacterial Imprints on Struvite-containing Kidney Stones: A Structural Investigation at the Mesoscopic and Atomic Scale
Dominique Bazin,Gilles André,Raphael Weil,Guy Matzen,Veron Emmanuel,Xavier Carpentier,Michel Daudon +6 more
TL;DR: Bacterial imprints may appear more easily on kidney stones with small nanocry crystals, such as carbonated apatite than with large nanocrystals, suchAs struvite, which may help identify bacteria contributing to stone formation.
