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.
Cysts can occur anywhere on the body, including the skin, on the knee, over the brain and on the kidneys and women can also get cysts in the breast, vagina, cervix, or ovaries. They can be caused by infections, developed from genetic predisposition, parasitic infection, injury, a defect in the cells, or blocked ducts.
