Artificial Spleen Removes Ebola, HIV Viruses And Toxins From Blood Using Magnets by Oblitz(m): 9:39pm On Sep 16, 2014 |
Harvard scientists have invented a new artificial spleen that is able to clear toxins, fungi, deadly pathogens and viruses such as Ebola from human blood, which could potentially save millions of lives. When antibiotics are used to kill them, dying bacteria release toxins in the blood that begin to multiply quickly, causing sepsis, a life-threatening condition whereby the immune system overreacts, causing blood clotting, organ damage and inflammation. To overcome this, researchers have invented a " biospleen ", a device similar to a dialysis machine that makes use of magnetic nanobeads measuring 128 nanometres in diameter (one-five hundredths the width of a single human hair) coated with mannose-binding lectin (MBL), a type of genetically engineered human blood protein. The device uses a modified version of mannose- binding lectin (MBL), a protein found in humans that binds to sugar molecules on the surfaces of more than 90 different bacteria, viruses and fungi, as well as to the toxins released by dead bacteria that trigger the immune overreaction in sepsis. The researchers coated magnetic nanobeads with MBL. As blood enters the biospleen device, passes by the MBL-equipped nanobeads, which bind to most pathogens. A magnet on the biospleen device then pulls the beads and their quarry out of the blood, which can then be routed back into the patient. According to researchers, the biospleen could also help to treat viral diseases such as HIV and Ebola, in which survival depends on lowering the amount of virus in the blood to a negligible level. His group is now testing the biospleen on pigs. http://www.nature.com/news/artificial-spleen-cleans-up-blood-1.15917 1 Like

Nice piece of technology. Good to see innovative researchers putting out new devices to aid mankind. Sadly they never seem to be Africans. |
