A team of international researchers has transferred eye tissue from newborn to adult mice. It lets the blind adults detect light. The scientists say it challenges conventional wisdom on stem cells, because the successful cells had already stopped dividing before they were transferred.
Argonne National Laboratory scientists in collaboration with Xradia have created a new X-ray microscope technique capable of observing molecular-scale features, measuring less than a nanometer in height. Combining X-ray reflection together with high resolution X-ray microscopy, scientists can now study interactions at the nanometer-scale which often can exhibit different properties. Improving our understanding of interactions at the nanoscale holds promise to help us cure the sick, protect our environment and make us more secure.
University of Illinois at Chicago researchers are comparing two drugs commonly used to treat attention deficit hyperactivity disorder to determine if genetic factors predict which children will respond to either or both drugs.
Hodgkin?s lymphoma survivors who have lipid screening every five years to detect high cholesterol will live a half year longer than patients who don?t have the screening and the intervention is cost-effective, according to a study presented November 8, 2006, at the American Society for Therapeutic Radiology and Oncology?s 48th Annual Meeting in Philadelphia.
Researchers at the Johns Hopkins Kimmel Cancer Center have for the first time implicated the muscle protein myosin VI in the development of prostate cancer and its spread.
Mayo Clinic Cancer Center’s Specialized Programs of Research Excellence (SPORE) grant from the National Cancer Institute (NCI) for prostate cancer research has been renewed for an additional five years. SPORE grants are highly competitive awards given to institutions on the cutting edge of translational research in specific types of cancer.
A special research program at St. Joseph’s Hospital and Medical Center is providing a safe and vital research component to scientists in hopes of finding new treatments and cures for a variety of disorders.
The American Thoracic Society (ATS) has published a new statement on the pathogenesis, prevention and treatment of liver damage caused by anti-tuberculosis (TB) medications. The statement, which appeared in the October 15 issue of the American Journal of Respiratory and Critical Care Medicine, gives a review of current national and international literature on drug-induced liver injury (DILI) or hepatotoxicity, a potential side effect of more than 700 drugs approved for use in the United States.
Researchers at the Jackson Laboratory, in collaboration with scientists at Bristol-Myers Squibb Oncology, discovered is that imatinib does not inactivate all BCR-ABL signaling pathways in the cascade. Proteins called SRC kinases are still activated by BCR-ABL in imatinib-treated mouse leukemic cells. Treatment with dasatinib, which inhibits the SRC proteins as well as BCR-ABL, was not only more effective for CML, but also led to complete B-ALL remission.
Rutgers researchers have discovered that the Chlamydia bacterium, which causes a sexually transmitted disease (STD), shares an evolutionary heritage with plants. That shared evolutionary heritage, which is not found in most other bacteria, points to a prime target for development of an effective cure for Chlamydia infections.
