A Survey on the Presence of Calcifying Nanoparticles in Renal Stones, Gallbladder Stones and Atherosclerosis Plaque

Several diseases are linked to nano-bacteria including kidney stones, gallbladder stone, cardiovascular plaques, oral–dental plaque, many cancers, and autoimmune diseases. The aim of this study was to a...
