Science and technology in Argentina Argentina have enjoyed an international respect since the turn of the 1900s, when Dr. Luis Agote devised the first safe and effective means of blood transfusion as well as René Favaloro, who was a pioneer in the improvement of the bypass surgery . Argentina is the Latin American country with the most Nobel Prize laureates; and has three Nobel Prize winners in the sciences: Bernardo Houssay in Physiology or Medicine in 1947, Luis Federico Leloir in Chemistry in 1970, and César Milstein in Physiology or Medicine in 1984. Dr. Domingo Liotta created the first artificial heart in 1969, revolutionizing the
Artificial cell cells have been proposed as a non-viral vector by which genetically modified non-autologous cells are encapsulated and implanted to deliver recombinant proteins "in vivo". This type of immuno-isolation has been proven efficient in mice through delivery of artificial cells containing mouse growth hormone which rescued a growth-retardation in mutant mice. A few strategies have advanced to human clinical trials for the treatment of pancreatic cancer, lateral sclerosis and pain control. The first clinical use of artificial cells was in hemoperfusion by the encapsulation of activated charcoal. Activated charcoal has the capability of adsorbing many large molecules and has for a
