Stress tests are good front-line tests indicators of heart disease, but just how good depends on ordering the right one, researchers say. Thirty percent of all women, for example, have a false positive exercise treadmill test, in which they walk for several minutes at a slightly increasing incline with an electrocardiogram measuring the electrical activity of the heart, they say.
One year after completing the first large-scale report sequencing breast and colon cancer genes, Johns Hopkins Kimmel Cancer Center scientists have studied the vast majority of protein-coding genes which now suggest a landscape dominated by genes that each are mutated in relatively few cancers.
Through the generous philanthropic support of the Littlefield 2000 Trust, the American Association for Cancer Research is pleased to announce four recipients of the 2007 Jeannik M. Littlefield-AACR Grants for Metastatic Colon Cancer Research, totaling $2.7 million. Now in its second year, this competitive grant program supports the cutting-edge research of top scientists from around the world, working to accelerate the discovery and development of new treatments for metastatic colon cancer.
In rats with portal hypertension, ultra¨Clow-dose aspirin has shown a normalizing effect of platelet-endothelial cell alterations and bleeding time. Further, this effect is mediated by Cyclooxygenase 2 inhibition.
A team of researchers from China and the University of Oregon have developed an approach for neuroscientists to study how meditation might provide improvements in a person’s attention and response to stress.
Researchers have discovered a key protein that controls how stem cells “choose” to become either skeletal muscle cells that move limbs, or smooth muscle cells that support blood vessels, according to a study published today in the Proceedings of the National Academy of Sciences (PNAS).
Hartmut “Hucky” Land, Ph.D., professor and chair of the Department of Biomedical Genetics, will give a talk titled “Construction and Deconstruction of Cancer Cells,” as part of a lecture series highlighting biological and biomedical research at the University of Rochester.
Patients and physicians are invited to a Lupus Education Day to learn more about an oft-misunderstood disease, but one for which several potential new treatments are in development.
A research team combining high-energy physicists from the University of California, Santa Cruz, and neuroscientists from the Salk Institute in La Jolla, Calif., has discovered a type of retinal cell that may help monkeys, apes, and humans see motion. The team’s work appears in the October 10 issue of Journal of Neuroscience.
African-American men are more likely to have their prostate cancer return after treatment, but their disease is no more aggressive when it does recur than that of their white counterparts, according to a study led by Duke Prostate Center researchers.
