Healing the heart with bone marrow cells

...tral to the exciting new field called regenerative medicine which aims to restore, repair and regenerate damaged organs rather than merely treating the symptoms of disease. According to Dr. Weisel, "One treatment resulting from this discovery was to inject cells genetically modified to release large amounts ...

Large-scale genomics project will hunt genes behind common childhood diseases

... genetic profile represents an era of personalized medicine still in its early stages. Part of the research task ahead, said Dr. Hakonarson, is not only to map gene variants to disease risk, but also to investigate how genes interact with environmental factors. "We will be tracing the major underlying genet...

CHAVI announces international search for genes affecting HIV response

...ector Barton Haynes, M.D. Haynes is a professor of medicine and director of the Human Vaccine Institute at Duke University Medical Center. Despite repeated exposures, some people apparently never become infected with HIV. Among those who become infected, there is dramatic variation in how the body responds t...

Magnetism and mimicry of nature hold hope for better medicine, environmental safety

Critical advances in medicine and environmental protection promise to emerge from a new method for biochemical analysis of fluids developed by an international science team led in part by Arizona State University researchers. Called "digital magnetofluidics," it promises more r...
