New St. Jude treatment alleviates long-term anemia and organ damage in mice and paves the way for human applicationsUsing a harmless virus to insert a corrective gene into mouse blood cells, scientists at St. Jude Children's Research Hospital have alleviated sickle cell disease pathology. In their studies, the researchers found that the treated mice showed essentially no difference from normal mice. Although the scientists caution that applying the gene therapy to humans presents significant...

A new "barcode chip" developed by researchers at the California Institute of Technology (Caltech) promises to revolutionize diagnostic medical testing. In less than 10 minutes, and using just a pinprick's worth of blood, the chip can measure the concentrations of dozens of proteins, including those that herald the presence of diseases like cancer and heart disease. The device, known as the Integrated Blood-Barcode Chip, or IBBC, was developed by a group of Caltech researchers led by James R....

Scientists at Penn State University report learning more about some of the processes regulating genes and the evolution of the DNA regions that control genes. The team focused on regulatory regions that, when bound to a certain protein, are thought to stimulate the genes that play a key role in developing red blood cells, the university said in a news release. The results could help the development of drugs to treat sickle-cell anemia and other blood disorders, researchers said.

Two presentations during the American Society of Nephrology's Renal Week demonstrated that frequently monitoring hemoglobin during hemodialysis will provide physicians with trending information that may reduce hemoglobin variability. The study demonstrated increased time-in-target range for hemoglobin in end-stage renal disease patients. The study suggests that increased frequency of hemoglobin monitoring may contribute to more accurate dosing for anti-anemia medication (e.g., erythropoietin...

CaridianBCT, a developer and marketer of blood collection and processing systems to hospitals and blood banks, has initiated a clinical trial for treating whole blood with Mirasol pathogen reduction technology after receiving clearance from the FDA and US Department of Defense. The Mirasol pathogen reduction technology (PRT) system is a proprietary technology that uses riboflavin and UV light to reduce the levels of infectious pathogens and inactivate white cells from collected blood,...

British and U.S. scientists say nearly 7 million pregnant women in sub-Saharan Africa are infected with hookworms and, therefore, are at risk of anemia. Hookworms are parasitic worms that live in the intestine and can cause a lower than normal number of red blood cells. In a systematic search of medical databases, reference lists and unpublished data, the scientists were able to compare levels of hemoglobin -- the oxygen-carrying part of red blood cells -- according to the intensity of...

MONTVALE, N.J., Sept. 11 /PRNewswire-FirstCall/ -- Synvista Therapeutics, Inc. today announced findings from a study that indicated Synvista's proprietary monoclonal enzyme immunoassay can determine a person's haptoglobin pheno/genotype in less than two hours, and can aid physicians in predicting cardiovascular risk in patients with diabetes. The study was presented today at the 2008 Cardiovascular Biomarkers and Surrogate Endpoints Symposium in Bethesda, Maryland. "This study shows the...

By Wendi C Thomas Just to look at them - Shevett Pratcher, Kelsey Stinnes and Jamena Polk - you'd never know what their lives are like. Their smiles come easy, their sense of humor is intact, despite living with the debilitating disease of sickle cell. On Wednesday, Pratcher and Polk were at the Diggs-Kraus Sickle Cell Center at the Regional Medical Center at Memphis, Pratcher because of leg pain and Polk for an IV of fluids to help rehydrate her as she's weaned off pain medication....

By Malcolm Ritter Associated Press NEW YORK -- Scientists say they've found an efficient way to make red blood cells from human embryonic stem cells, a possible step toward making transfusion supplies in the laboratory. The promise of a virtually limitless supply is tantalizing because of blood donor shortages and disappointments in creating blood substitutes. Red blood cells are a key component of blood because they carry oxygen throughout the body. Experts called the new work an...

The study of dark-skinned mice has led to a surprising finding about a common protein involved in tumor suppression, report researchers at the Stanford University School of Medicine. The results may lead to new treatments for bone marrow failure in humans. The protein, called p53, has been dubbed the "guardian of the genome" for its ability to recognize DNA damage and halt the division of potentially cancerous cells. However, in a new twist, it appears that p53 also responds to...
