Popeye was right — eat your spinach. In fact, add some fresh-cut apples to that spinach salad.
Two new animal studies by researchers at the University of South Florida Center for Aging and Brain Repair and James A. Haley Veterans Hospital bolster a growing body of evidence that certain fruits and vegetables may protect the brain against the ravages of age. The complementary research papers appear in today’s issue of the Journal of Neuroscience.
“If these pre-clinical fin
One or two drinks a day can raise the risk of developing hypertension in some men, according to two Japanese studies. The studies, published in the July issue of Alcohol: Clinical Experience and Research, found that men who had as few as one or two glasses of alcohol on a regular basis had a much higher incidence of hypertension than those who did not drink at all. Several U.S. studies have found that moderate drinking habits can actually decrease the risk of heart disease. A
Over the past few years, covalent modifications of histone tails have emerged as an important mechanism of gene regulation in eukaryotes. Now, scientists have identified a major euchromatic histone methyltransferase in mammalian cells that is crucial for normal embryonic development, and possibly the prevention of cancer. In a report published in Genes & Development, Dr. Yoichi Shinkai and colleagues have identified a protein called G9a as an enzyme that adds a methyl group to the lysine 9 amino acid
The U.S. Food and Drug Administration has asked for additional information, but no additional clinical trials, as it considers approval of FluMist, an influenza vaccine delivered as a nasal spray. FluMist was invented by Hunein “John” Maassab after more than four decades of research at the University of Michigan School of Public Health. Gaithersburg, Md.-based MedImmune has licensed the rights to FluMist from U-M, and has a marketing agreement with pharmaceutical giant Wyeth. “I am
Disease-free survival from advanced prostate cancer could be almost doubled if hormone-suppression therapy is used during and after radiotherapy for a duration of 3 years, suggest authors of an international study in this week’s issue of THE LANCET.
Long-term survival after radiotherapy for people with advanced prostate cancer is poor. Michel Bolla from University Hospital, Grenoble, France, and colleagues investigated the added value of long-term male-hormone (androgen) suppression in locally ad
Ecological communities suffer dramatic changes when non-native species are introduced by humans. Such introductions have been documented in hundreds of locations and appear to be common in marine and island habitats. One of the best-studied cases of a species that suddenly appeared in the New England intertidal, and subsequently spread rapidly southward accompanied by significant changes in the intertidal community, is the “European periwinkle” Littorina littorea. In the July issue of Ecolog
