Having a virtual copy of a patient's blood in a computer would be a boon to researchers and doctors. They could examine a simulated heart attack caused by blood clotting in a diseased coronary artery and see if a drug like aspirin would be effective in reducing the size of such a clot.

 | The cells that coat the pipes leading to the heart cling more tightly together in areas of fast-flowing blood. The discovery could help to reduce vascular leakage and better treat heart disease. ...> Full Article |
 | Max Planck researchers unravel a critical regulatory mechanism controlling blood vessel growth that might help solve drug resistance problems in the future.

 | Hans Vogel, a professor at the University of Calgary, recently published research that helps to better understand the blood clotting process. Vogel and his graduate student Hao Huang were able to determine the molecular 3-D structure of a protein in blood platelets and a receptor that sticks through the membrane of the cell to the outside. Other scientists have unsuccessfully attempted to map this structure, but Huang and Vogel were the first to make it work. ...> Full Article |
Yale researchers have discovered how megakaryocytes -- giant blood cells that produce wound-healing platelets -- manage to grow 10 to 15 times larger than other blood cells.
The findings, to be published March 13 in the journal Developmental Cell, also hint at how a malfunction in this process may cause a form of leukemia.

 | For the first time in nearly a decade, two new blood types have been identified. Thirty proteins had previously been identified as responsible for basic blood types, like the well-known ABO and Rhesus types. Now two additional proteins have been shown to be responsible for two new blood types called Langereis and Junior. This discovery--by an international team from Vermont, France, Japan and Italy -- will help certain patients with transfusions, transplants and mother/fetus problems. ...> Full Article |
Scripps Research Institute scientists have discovered new elements of the blood clot-formation process. The findings could lead to better drugs for preventing heart attacks and other clot-related conditions.

 | A novel type of biomedical imaging, made possible by new advances in microscopy from scientists at Harvard University, is so fast and sensitive it can capture "video" of blood cells squeezing through capillaries. The new technique makes possible label-free chemical movies, with streaming footage at the subcellular level, catching video of proteins, lipids, and water within cells. ...> Full Article |
Researchers at UT Southwestern Medical Center have uncovered a key step in the creation of new red blood cells in an animal study.

 | Scientists are reporting development of the first "dipstick" test for instantly determining a person's blood type at a cost of just a few pennies. Their study on the test, which involves placing a drop of blood on a specially treated paper strip, appears in ACS' semi-monthly journal Analytical Chemistry, where the authors say it could be a boon to health care in developing countries. ...> Full Article |
 | Thanks to an interdisciplinary team of researchers, scientists now have a more complete understanding of one of the human body's most vital structures: the red blood cell. Led by University of Illinois professor Gabriel Popescu, the team used diffraction phase microscopy to measure fluctuation in the cell membrane and developed a model that could lead to breakthroughs in screening and treatment of blood-cell-morphology diseases, such as malaria and sickle-cell disease. ...> Full Article |
Galectin-4 and galectin-8, carbohydrate-binding proteins found in our intestines, can recognize and kill bacteria that have human blood type sugar molecules on their surfaces. This discovery explains why bacteria can't sneak past our immune systems by camouflaging themselves with blood type molecules. It may also explain why the human population has a diversity of blood types; galectin-4 and -8 create a "protected space" for the diversity.

Three years after the US blood banking industry issued recommendations that discourage transfusing plasma from female donors because of a potential antibody reaction, Duke University Medical Center researchers discovered that female plasma actually may have advantages.
