OBJECTIVES Randall initially described calcified subepithelial papillary plaques, which he hypothesized as nidi for urinary calculi. The discovery of calcifying nanoparticles (CNP), also referred to as nanobacteria, in calcified soft tissues has raised another hypothesis about their possible involvement in urinary stone formation. This research is the first(More)
The nanotechnology industry is currently in the process of producing new nanoparticles. The biological activity of nanoparticles including adverse as well as beneficial effects tends to increase as their size decreases. The smaller the particles are, the greater their bioactivity and toxicity. Thus, one can easily conjecture the impact ofa nanoparticle if(More)
The potential of the metal-binding protein, metallothionein, in assessing the progression of normal oesophagus through Barrett's to adenocarcinoma was investigated. Metallothionein was quantitatively determined in resected tissues from patients undergoing oesophagectomy for high grade dysplasia/adenocarcinoma and in biopsies from patients with Barrett's(More)
