In a study, college-age women who were concerned about their eating behaviors reported that moods worsened after bouts of disordered eating, said Kristin Heron, research associate at the Survey Research Center.

"There was little in the way of mood changes right before the unhealthy eating behaviors," said Heron. "However, negative mood was significantly higher after these behaviors."

White blood cells found to play key role in controlling red blood cell levels

Posted: 17 Mar 2013 02:40 PM PDT

Researchers at Albert Einstein College of Medicine of Yeshiva University and the Icahn School of Medicine at Mount Sinai have found that macrophages – white blood cells that play a key role in the immune response – also help to both produce and eliminate the body's red blood cells (RBCs). The findings could lead to novel therapies for diseases or conditions in which the red blood cell production is thrown out of balance. The study, conducted in mice, is published today in the online edition of the journal Nature Medicine.
