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.
Facts about the condition. 1. Polycystic kidney disease causes cysts, which are non cancerous fluid-filled sacs, to develop inside the kidneys. Cysts can develop anywhere inside the body, but the kidneys are the most affected. 2. Polycystic kidney disease can exist for a long time before any symptoms occur. When they do occur, symptoms may be high blood pressure, back and side pain, headache, swollen abdomen, frequent urination that may have blood in it, kidney stones, kidney infections and kidney failure.
