COLUMBIA, Mo. — Each year, about 610,000 Americans suffer their first heart attack, according to the Centers for Disease Control and Prevention. Heart attacks and other symptoms of cardiovascular disease can be caused when blockage occurs in the arteries. In a new study from the University of Missouri, a scientist has discovered a natural defense against arterial blockage: bilirubin.

Bilirubin is typically something parents of newborns hear about when their children are diagnosed with jaundice. Generated during the body’s process to recycle worn-out red blood cells, bilirubin is metabolized by the liver and, usually, leaves the body harmlessly. (Many babies’ livers are not developed enough to metabolize the bilirubin, which results in the infants being diagnosed with jaundice, or high levels of bilirubin in their systems.) Now, MU scientists have found that bilirubin can be used to inhibit the clogging of arteries, and thus prevent the deadly consequences often experienced by individuals with cardiovascular disease.

In a new analysis of thousands of U.S. women of childbearing age, Brown University researchers found that most exceeded the median blood level for two or more of three environmental pollutants that could harm brain development of fetuses and babies: lead, mercury, and polychlorinated biphenyls (PCBs).

PROVIDENCE, R.I. [Brown University] — Nearly 23 percent of American women of childbearing age met or exceeded the median blood levels for all three environmental chemical pollutants — lead, mercury, and PCBs — tracked in an analysis of data on thousands of women by Brown University researchers. All but 17.3 percent of the women aged 16 to 49 were at or above the median blood level for one or more of these chemicals, which are passed to fetuses through the placenta and to babies through breast milk.

The Placebo Effect Goes Beyond Humans, UF Researchers Find

GAINESVILLE, Fla. — Rats and humans have at least one thing in common: They both react the same way to a placebo, according to a new University of Florida study.

“That was the big finding — that the animals that expected pain relief actually got pain relief when you gave them an inert substance,” said co-author John Neubert, a pain specialist and an associate professor with the UF College of Dentistry department of orthodontics. “It helps validate our model that what we do in the rats, we believe, is a good representation of what’s being seen in humans.”

The investigation of placebo effects might lead to the identification of new therapeutic targets in the brain and of novel treatment strategies for a variety of health conditions. (more…)
