WINSTON-SALEM, N.C., June 25 /PRNewswire-USNewswire/ -- The National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health, announced June 21st that it will fund nine research grants to improve the safety of red blood cell transfusions. Wake Forest University Professor of Physics Daniel Kim-Shapiro and a collaborator at the University of Pittsburgh have been awarded a $2.8 million, four-year grant to study why the quality of stored blood degrades over time and to...

German scientists said Wednesday that legendary pharaoh Tutankhamun was probably killed by the genetic blood disorder sickle cell disease. The team questioned the conclusions of a major Egyptian study released in February on the enigmatic boy-king's early demise.  The researchers were from the Bernhard Nocht Institute for Tropical Medicine in the northern city of Hamburg. The scientists said he died of malaria after suffering a fall, putting to rest the theory that he was...

Discovery of a key red cell molecule used by the malaria parasite gives renewed hope for an effective vaccine in the future, according to an international team of researchers. Plasmodium falciparum, a blood parasite that causes malaria by invading and multiplying in the red blood cells, kills 1 to 2 million people annually. "How the parasite invades red blood cells is not completely understood," said Jose A. Stoute, M.D., senior investigator and team leader, Department of Medicine, Division...

A new study pinpoints the genetic changes that enable Tibetans to thrive at altitudes where others get sick. In the online edition of Proceedings of the National Academy of Sciences, an international team has identified a gene that allows Tibetans to live and work more than two miles above sea level without getting altitude sickness. A previous study published May 13 in Science reported that Tibetans are genetically adapted to high altitude. Now, less than a month later, a second study by...

By capturing movies of both the blood and vasculature of zebrafish embryos, each less than two millimeters long, researchers have been able for the first time to see the very moment that blood begins to flow. The observations, reported online on June 3rd in Current Biology, a Cell Press publication, show that the earliest blood flow, involving what appear to be hundreds of cells, begins all at once. Remarkably, that onset of life-giving circulation takes more than a beating heart. In fact,...

New treatments for malaria are possible after Walter and Eliza Hall Institute scientists found that molecules similar to the blood-thinning drug heparin can stop malaria from infecting red blood cells. Malaria is an infection of red blood cells that is transmitted by mosquitoes. The most common form of malaria is caused by the parasite Plasmodium falciparum which burrows into red blood cells where it rapidly multiplies, leading to massive numbers of parasites in the blood stream that can...

EMBL scientists identify molecules that ensure red blood cell production Red blood cells, the delivery men that take oxygen to cells all around the body, have short lives. To keep enough of them in circulation, the human body produces around 2 million of these cells every second "“ even more in response to challenges like severe blood loss. In a study published today in the Journal of Experimental Medicine, scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo,...

MUMBAI, India, May 13, 2010 /PRNewswire/ -- Fortis Hospitals Mulund, Mumbai, performed a multiple joint replacement surgery on a 27 year old young Nigerian patient. Rebacca underwent a hip and a shoulder replacement surgery by Dr. Sachin Bhonsle, Consultant Orthopedic Surgeon, after years of suffering in pain and immobility. Rebecca was suffering from a sickle cell disease since birth; an inherited (genetic) disorder where the RBC (red blood corpuscles) assumes an abnormal shape of a...

Adults who have mild sickle cell disease scored lower on brain function tests when compared to healthy participants, suggesting the blood disease may impact the brain more than previously realized, according to new research published in the May 12 issue of the Journal of the American Medical Association. This is the first study to examine cognitive functioning in adults with sickle cell disease. The study was conducted by 12 sites within the Comprehensive Sickle Cell Centers funded by the...

Scientists discovered that mammoths had blood that displayed "antifreeze" like qualities, which kept their bodies supplied with oxygen at sub-zero temperatures. The journal Nature Genetics reported that scientists extracted a blood protein, known as hemoglobin, from mammoth remains. The study of the hemoglobin led researchers to find those antifreeze properties. The hemoglobin protein is found in red blood cells where it binds to and carries oxygen. The scientists found that mammoths...
