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.

Using multiple forms of media at the same time – such as playing a computer game while watching TV – is linked to symptoms of anxiety and depression, scientists have found for the first time.

Michigan State University’s Mark Becker, lead investigator on the study, said he was surprised to find such a clear association between media multitasking and mental health problems. What’s not yet clear is the cause. (more…)

BANGALORE, India — Dec. 3, 2012 — Giri Prasad, a 33-year-old tailor who lives in Delhi, first noticed the pain below his ribs. He went to see a doctor, but when it didn’t subside, he traveled to the hospital where he eventually learned he had tuberculosis.

“There were many problems because first and foremost, I am the bread earner for the family,” he says. “If the bread earner falls ill, it is a real problem for those who are dependent on him. Here in the city the biggest problem is that if one falls sick, there is no other person who will come help.” (more…)

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…)

For those searching for deeper meaning in a failed marriage, writing about their feelings soon after divorce may lead to greater emotional distress, according to new research.

Following a divorce or separation, many people are encouraged by loved ones or health-care professionals to keep journals about their feelings. But for some, writing in-depth about those feelings immediately after a split may do more harm than good, according to new research conducted at the University of Arizona.

In a study of 90 recently divorced or separated individuals, UA associate professor of psychology David Sbarra and colleagues found that writing about one’s feelings can actually leave some people feeling more emotionally distraught months down the line, particularly those individuals who are prone to seeking a deeper meaning for their failed marriage.
