Weizmann Institute scientists have uncovered a key mechanism that enables stem cells to exit the bone marrow into the blood circulation of healthy donors, as well as patients suffering from leukemia, other malignancies and blood disorders. Published in the current July issue of Nature Immunology, the findings may lead to more efficient clinical stem cell transplantations.

Bone marrow transplantation is a last-resort treatment that saves the lives of many patients with cancer and inherited b

Findings important in developing new drugs to treat inflammatory vascular diseases

An enzyme that stimulates the production of chlorine bleach in cells to kill bacteria and other invading pathogens also turns off a signal that regulates blood vessel dilation during inflammation, researchers at the UC Davis School of Medicine and Medical Center have found.

The research — conducted in collaboration with scientists at the University of Alabama at Birmingham, UCLA and the Unive

Almonds are a prime example, providing more alpha-tocopherol vitamin E than any other nut, and lowering LDL or “bad” cholesterol levels

Three studies released this week give the term “health nut” new meaning, as they tie the consumption of nuts with a lower risk of Alzheimer’s disease and sudden heart attacks.

Two studies published in the Journal of the American Medical Association suggested that the antioxidant vitamin E and other antioxidants in nuts, leafy green vegetabl

Scientists at the University of Virginia Health System have identified another step in the mysterious process of gene regulation — what turns genes on or off, making them cause or suppress disease and other physical developments in humans. As reported in this week’s issue of the scientific journal Nature, a chemical group called ubiquitin has been shown to lie upstream of a switch that seems to control whether a gene is on or off. “Ubiquitin was first discovered on histones long ago, but before thi

Further study may help make biomedical devices safer and explain urinary tract infections

Researchers at the University of Washington have learned that something most people take for granted is not true: that the force of fluids within the human body helps to break the adhesive bonds of invasive bacteria and counterbalance infection.

Most scientists as well as lay people assume, for example, that a sneeze helps clear infection, or that urine helps to clear bacteria from the

A newly developed polymer surface could improve the interface between electronic implants and living tissue, helping to advance a technology that may one day enable the blind to see and the paralyzed to walk. The findings were described today at the 34th Central Regional Meeting of the American Chemical Society, the world’s largest scientific society. The meeting is being held at Eastern Michigan University in Ypsilanti.
