Does eating during TV viewing affect preschool children's intake? Yes

In a recent Penn State laboratory study, preschool children who usually eat meals at home while watching TV ate one-third more lunch when they were shown a cartoon video during lunchtime versus when they ate lunch without TV.

Research provides clues to obesity's cause

Hot fudge sundaes and french fries aside, new research suggests obesity is due at least in part to an attraction between leptin, the hormone that signals the brain when to stop eating, and a protein more recently associated with heart disease.

Statins may be able to play a role in preventing or slowing heart valve disease

Research to be published in the April 18 issue of the Journal of the American College of Cardiology provides the first explanation of an active rather than passive process that leads to heart valve degeneration, furthering a Northwestern researcher's effort to lead a paradigm shift in the medical community's beliefs about the cause of valve disease.

New model of p53 regulation has important implications for the development of anticancer drugs

Genetically engineered mice convinced scientists at the Salk Institute for Biological Studies that it was time to overhaul widely held beliefs about how a powerful tumor suppressor called p53 is controlled in cells. Their new model of p53 regulation has important implications for the development of anticancer drugs.

Research explains why recipients of growth hormone therapy may develop colon polyps

The use of growth hormone therapy has been linked in some people to the development of colon polyps, a possible precursor to colorectal cancer - but medical researchers have debated the extent of a cancer risk.

St. John's wort and Echinacea increase activity of enzyme in the liver and intestine

St. John's wort and Echinacea, two widely-used herbal preparations, have been found to increase activity of a specific enzyme in the liver and intestine, an enzyme involved in the metabolization of roughly one in every four pharmaceutical drugs on the market today, reports a clinical pharmacologist at Indiana University School of Medicine.

Researchers unravel structure of important new drug target that could potentially treat SARS-infected patients

Mesecar said that the knowledge gained from this new atomic structure - the first-ever reported on this class of proteases - has the potential to go beyond the treatment of patients infected with the coronavirus that causes SARS.
