The particle therefore becomes a small radiating dipole whose radiation we see as scattered light. Rayleigh scattering of sunlight in the atmosphere causes diffuse sky radiation, which is the reason for the blue color of the sky and the yellow tone of the sun itself.
Plasmapheresis is a process in which the liquid in the blood, or plasma, is separated from the cells. In sick people, plasma can contain antibodies that attack the immune system. A machine removes the affected plasma and replaces it with good plasma, or a plasma substitute.This is also known as plasma exchange.The process is similar to kidney dialysis. Plasmapheresis also can refer to the plasma donation process, where the plasma is removed and cells are returned to the body.Plasmapheresis can be used to treat a variety of autoimmune disorders, including myasthenia gravis, Guillain-Barre syndrome, and Lambert-Eaton. It can also be used to treat multiple sclerosis. machine removes the affected plasma and replaces it with good plasma, or a plasma substitute. This is also known as plasma exchange.

Plasmapheresis and Multiple Sclerosis. The purpose of this procedure is to eliminate antibodies from human blood and preventing them from assaulting their intended targets. In people with multiple sclerosis, the antibodies target the own body cells of the person.
