Eltrombopag, a drug that was designed to stimulate production of platelets from the bone marrow and thereby improve blood clotting, can raise blood cell levels in some people with severe aplastic anemia who have failed all standard therapies. About one-third of aplastic anemia cases do not respond to standard therapy, a combination of immune-suppressing drugs. Although bone marrow stem cell transplantation is an option for some, patients without a matched donor have few treatment options....

Bioinformaticians of Jena University calculated the optimal value of hematocrit with the help of Einstein's equation When people say "Blood is thicker than water," they are literally right. Because nearly half of the 'life liquid' consists of solid components. The red blood cells form the greatest part of it — all in all around 40 percent of the blood. They contain the red pigment hemoglobin and are responsible for the transport of oxygen. "It is amazing that the percentage of...

The transfusion of red blood cells (RBC) is a critical component in the treatment of a number of acute and chronic medical problems. Indeed, approximately 75 million units of whole blood (~34 million liters) are annually collected worldwide for processing and eventual transfusion. Despite this massive collection effort, the need for blood constantly exceeds availability due to a combination of collection, manufacturing, storage and biological (i.e., immunological) issues. The immunological...

Researchers have rejuvenated aged hematopoietic stem cells to be functionally younger, offering intriguing clues into how medicine might one day fend off some of the ailments of old age. Scientists at Cincinnati Children's Hospital Medical Center and the Ulm University Medicine in Germany report their findings online May 3 in the journal Cell Stem Cell. The paper brings new perspective to what has been a life science controversy — countering what used to be broad consensus that the...

Image Credit: © South Tyrol Museum of Archaeology Research of wounds on a 5,300-year-old body found frozen in the Italian Alps in 1991 has produced the oldest red blood cells ever identified, and suggests the well preserved “Iceman” did not immediately die from his injuries, nor did he live for a few days, scientists report in the Journal of the Royal Society Interface. The bloody discovery is a first for the “Iceman,” called Oetzi, which has been...

Johns Hopkins study shows wide variation in transfusion use in operating rooms Citing the lack of clear guidelines for ordering blood transfusions during surgery, Johns Hopkins researchers say a new study confirms there is still wide variation in the use of transfusions and frequent use of transfused blood in patients who don't need it. The resulting overuse of blood is problematic, the researchers say, because blood is a scarce and expensive resource and because recent studies have...

A lot of people were skeptical when two young California-based researchers set out more than a decade ago to create a completely human-derived alternative to the synthetic blood vessels commonly used in dialysis patients. Since then, they've done that and more. "There were a lot of doubts in the field that you could make a blood vessel, which is something that needs to resist pressure constantly, 24-7, without any synthetic materials in it," explains Nicolas L'Heureux, a co-founder and the...

The theory that pigeons' famous skill at navigation is down to iron-rich nerve cells in their beaks has been disproved by a new study published in Nature. The study shows that iron-rich cells in the pigeon beak are in fact specialized white blood cells, called macrophages. This finding, which shatters the established dogma, puts the field back on course as the search for magnetic cells continues. "The mystery of how animals detect magnetic fields has just got more mysterious" said Dr...
