For the first time, researchers have successfully injected cultured red blood cells (cRBCs) created from human hematopoietic stem cells (HSCs) into a human donor, according to study results published today in Blood, the Journal of the American Society of Hematology (ASH). As the global need for blood continues to increase while the number of blood donors is decreasing, these study results provide hope that one day patients in need of a blood transfusion might become their own donors. http://medicalxpress.com/news/2011-09-successfully-cultured-red-blood-cells.html Medical research Thu, 01 Sep 2011 12:38:18 EST news234099468 In patients with acute myocardial infarction (heart attack), blood loss from greater use of phlebotomy (blood drawn for diagnostic testing) appears to be independently associated with the development of hospital-acquired anemia (HAA), according to a report published Online First by Archives of Internal Medicine, one of the JAMA/Archives journals.

This week in the early online version of Circulation, the team reports the latest findings from its ongoing exploration of the interaction between red blood cell breakdown products and nitric oxide (NO), revealing new biological mechanisms that can reduce blood flow and possibly damage vital tissues after administration of blood that has been stored for longer than 39 days. http://medicalxpress.com/news/2011-07-team-transfusion-blood-safe-age.html Cardiology Wed, 13 Jul 2011 14:57:27 EST news229787795 Old red blood cells shown to have undergone ?significant changes and damage?; techniques could help rapidly monitoring quality of blood supply. http://medicalxpress.com/news/2011-05-insight-quality-blood-transfusions.html Medical research Fri, 20 May 2011 07:56:55 EST news225097001 Years ago, identical twin baby boys received a blood transfusion tainted with HIV.
