Sickle-shaped red blood cells target and destroy tumor cells and blood vessels The genetic mutation that causes sickle cell anemia also turns red blood cells into potent tumor killers and may offer a new way to treat some cancers that are resistant to existing treatments, according to research published January 9 in the open access journal PLOS ONE by David S. Terman of Jenomic Research Institute and colleagues from Duke University and other institutions. The mutation that causes sickle...

Convergent Evolution Linked To Adaptation To High Altitudes

April Flowers for redOrbit.com - Your Universe Online A shared biological adaptation enables highlanders in both Tibet and Ethiopia to thrive in the low oxygen of high altitudes. A new study from Case Western Reserve University reveals that the ability to pass on this trait, however, appears to be linked to different genes in the two groups. The shared adaptation is the ability to maintain relatively low levels of hemoglobin for high altitudes. Hemoglobin is the oxygen-carrying protein...

Researchers at Duke University Medical Center may finally have discovered why people with sickle cell disease get milder cases of malaria than individuals who have normal red blood cells. In a finding that has eluded scientists for years, Duke researchers discovered that genetic material in red blood cells may help alter parasite activity via a novel mechanism that alters parasite gene regulation. "One of the most interesting findings in our study is that the human microRNA (very small...

A team of scientists from Albert Einstein College of Medicine in Bronx, NY, has developed methods to increase the production of red blood cells from stem cells, a discovery that could dramatically boost the blood supply available for transfusions. In the latest issue of STEM CELLS Translational Medicine, researchers Eric Bouhassira, Emmanuel Oliver, and Caihong Qiu published data on a promising new method of growing red blood cells in the lab. Durham, NC (PRWEB) August 02, 2012 A team of...

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...

callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
