Neodymium is never found in nature as a free element, but rather it occurs in ores such as monazite and bastnÃ¤site that contain small amounts of all the rare earth metals. The main mining areas are in China, the United States, Brazil, India, Sri Lanka, and Australia.
Polycystic Kidney Disease. Polycystic kidney disease (also called PKD) causes numerous cysts to grow in the kidneys. These cysts are filled with fluid. If too many cysts grow or if they get too big, the kidneys can become damaged. PKD cysts can slowly replace much of the kidneys, reducing kidney function and leading to kidney failure.
These cysts can be caused by infection, a blockage of a duct (causing a fluid build up), an inflammatory process, or just genetic bad luck! Usually you feel an abnormal lump underneath the skin, and that is a cyst; not painful, just a lump that is there, more annoying than anything.
