"Myeloablation" Natural Recordings by Native Speakers
Myeloablation is a medical term that refers to the destruction or removal of bone marrow, particularly in preparation for bone marrow transplantation. It can be performed using radiation therapy, chemotherapy, or a combination of both. The goal of myeloablation is to eliminate the patient's existing bone marrow and immune system, making it possible to transplant healthy stem cells and re-establish a new immune system.
Myeline refers to a fatty substance called myelin, which is produced by cells called oligodendrocytes in the central nervous system (CNS) and by Schwann cells in the peripheral nervous system (PNS). Myelin acts as an insulator, wrapping around nerve fibers and increasing the speed of nerve conduction by reducing electrical resistance. It also helps to protect the nerve fibers from damage. In medical contexts, demyelination refers to the process by which myelin is destroyed, often as a result of conditions such as multiple sclerosis.
Myelinosis is a condition characterized by the degeneration of the fatty tissue, called myelin, that surrounds and protects the nerve fibers in the brain. It is often caused by a deficiency of fat-soluble vitamins, particularly vitamin B12, and can also be caused by other factors such as kidney failure or liver disease. Symptoms of myelinosis can include numbness or tingling in the hands and feet, weakness or paralysis, blurred vision, and personality changes. Treatment typically involves correcting the underlying cause and managing symptoms with medications and other therapies.
