Liver regeneration may be simpler than previously thought
04-11-2007 · EurekAlert!The way the liver renews itself may be simpler than what scientists had been assuming. A new study, appearing in the April 13 issue of the Journal of Biological Chemistry, provides new information on the inner workings of cells from regenerating livers that could significantly affect the way physicians make livers regrow in patients with liver diseases such as cirrhosis, hepatitis or cancer.

- Children with gene show reduced cognitive function
11-05-2007 · EurekAlert!
Children possessing a gene known to increase Alzheimer's disease risk already show signs of reduced cognitive function, an Oregon Health & Science University study has found. Scientists discovered that 7- to 10-year-olds with a member of a family of genes implicated in development, nerve cell regeneration and neuroprotection display reduced spatial learning and memory, associated with later-life cognitive impairments. This suggests brain changes predisposing a person to Alzheimer's might occur much sooner than previously thought.

- New study indicates that people may need more dietary choline than previously thought
05-23-2007 · EurekAlert!
A new study published in the May issue of the American Journal of Clinical Nutrition indicates that the current recommended Adequate Intake (AI) for choline may, in fact, be inadequate for some people. Choline is an essential nutrient for normal functioning of all cells, including those involved with liver metabolism, brain and nerve function, memory, and the transportation of nutrients throughout the body.

- Study sheds important new light on inherited disorder causing iron overload
01-16-2008 · EurekAlert!
Research in today's New England Journal of Medicine shows hereditary hemochromatosis is much more common than previously thought and will spur more study to determine who is most likely to develop complications from the debilitating and potentially fatal disease, write two faculty members at the Saint Louis University School of Medicine.

- Studying rivers for clues to global carbon cycle
02-08-2008 · EurekAlert!
In the science world, media and our daily lives, the debate continues over how carbon in the atmosphere is affecting global climate change. In a study of how organic carbon is processed in rivers, a research team including an engineer, ecologists and microbiologists has determined that carbon processing in rivers is a bigger component of global carbon cycling than previously thought. The team lays out a framework for how scientists should go about assessing those processes.

- New study on school bus safety shows injuries well exceed previous reports
11-06-2006 · EurekAlert!
Each year in the United States, 23.5 million children travel 4.3 billion miles on 450,000 school buses -- and a new study shows that kids may not be as safe as previously thought. Researchers at the Columbus Children's Research Institute in Columbus, Ohio, found that an estimated 17,000 injuries occur annually -- three times more than previously reported.

- Effectiveness of over-the-counter decongestant questioned in new study
01-31-2007 · EurekAlert!
The only over-the-counter (OTC) oral decongestant currently available without restriction may be less effective than previously thought, according to a new study. This meta-analysis of 15 previous studies concludes that the standard 10 mg dose of the drug, found in popular products such as Actifed, Sudafed PE, and Tylenol Sinus, appears to be no more effective than placebo and suggests that the FDA should require additional studies to prove the drug's safety and efficacy.
