First evidence of cardiac progenitor cells

The first evidence of cardiac progenitor cells – rare, specialized stem cells located in the newborn heart of rats, mice and humans – has been shown by researchers at the University of California, San Diego (UCSD) School of Medicine. The cells are capable of differentiation into fully mature heart tissue.

Researchers find way to produce cholesterol-lowering snack chips

Brandeis University biology professor K.C. Hayes and Senior Research Associate Andy Pronczuk at the school's Foster Biomedical Research Laboratory, and Senior Scientist Daniel Perlman in the Physics Department have discovered a way to produce chips and other snack foods that can actually lower your cholesterol while you eat them - without having any impact on taste

New way to assess the potentially damaging effects of prenatal drug exposure

Scientists have demonstrated a new way to assess the potentially damaging effects of prenatal drug exposure--a technique that could also be used to monitor a fetus's response to therapeutic drugs--using sophisticated, noninvasive medical imaging tools.

Turning point in the history of preterm labor diagnosis

A combination of four proteins that result from inflammation and infection and lead to premature birth can be rapidly and accurately detected in the amniotic fluid of pregnant women using proteomics technology, Yale researchers report in two studies in the February issue of British Journal of Obstetrics and Gynecology.

Gene used in brain development can cause childhood brain cancers

A gene that's normally silenced after contributing to brain development was found to be expressed in cells from medulloblastoma, the most common form of pediatric brain malignancy in children, scientists report in an article published in the February 1 issue of the journal Cancer Research.

Compound, derived from a rare South American plant, stops the growth of human breast cancer cells

They started with a bare room and an idea. Now, after five years of painstaking, sophisticated tests, scientists at the University of Virginia Health System have discovered that a compound, derived from a rare South American plant, stops the growth of human breast cancer cells in laboratory cultures.

Relationship between weight gain and breast cancer survival

Women who are overweight prior to breast cancer diagnosis, or who are lean but gain weight following diagnosis, are more likely to have their disease return or die of the disease, a new study shows. This effect was found to be particularly pronounced among women who had never smoked. The study is published online in the Journal of Clinical Oncology (JCO).

Studying monkeys social judgments could provide clues to autism

Researches have found that monkeys will "pay" juice rewards to see images of high-ranking monkeys or female hindquarters. They say their research technique offers a rigorous laboratory approach to studying the "social machinery" of the brain and how this machinery goes tragically awry in autism -- a disease that afflicts more than a million Americans and is the fastest growing developmental disorder.

Physical traits, genetic test help with early diagnosis of aneurysm syndrome

A research team led by Johns Hopkins doctors has defined the physical traits and genetic basis of a new aortic aneurysm syndrome that is extremely aggressive and can cause death in early childhood. Early diagnosis of the syndrome and rapid surgical repair of the swollen aorta can save lives, the researchers report in the Jan. 30 advance online section of Nature Genetics.
