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.
Kidney cyst is a closed pouch containing fluid that forms in the kidneys. These cysts are most often non-cancerous. However, over time, when renal cyst grows to a certain size, it will oppress the kidney surrounding tissues or organs. In such a condition, it is easy to cause the burst of blood vessels. That is one reason how bleeding cyst occurs. In addition, causes of hemorrhagic cysts include surgery, chemotherapy, radiation, or infection. The bigger renal cysts can be removed by the surgery, but sometimes, the surgery will cause trauma on the cysts, which lead to hemorrhagic cysts.
