Trevor M. Penning is one of the authors on the paper, which serves as a nice companion to SOT’s official position on hydraulic fracturing on which Dr. Penning also contributed.

Three years ago, the National Toxicology Program listed styrene as “reasonably anticipated to be a human carcinogen” in its 12th Report on Carcinogens. Earlier this week, this ruling was affirmed by an independent National Research Council committee, on which four SOT members participated.

Lisbeth A. Boule, Bethany Winans, and B. Paige Lawrence’s study to determine exposure to an AhR ligand alters CD4+ T cell differentiation and function was published in Environmental Health Perspectives. The members found that maternal exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin did cause durable changes.

In another Environmental Health Perspectives paper, Thomas F. Webster and Jennifer J. Schlezinger investigated whether components of the flame retardant alternative Firemaster® 550 are biologically active peroxisome proliferator activated receptor γ (PPARγ) ligands. They found that there are components in Firemaster® 550 that bind and activate PPARy.

SOT Members in the News

Vickie Tatum told The Longview Daily News, “There is nothing in that body of research that suggests that any herbicide used in forests could or would have any relationship whatsoever to hoof rot.”

Last week, the US Food and Drug Administration (FDA) issued a warning to consumers to avoid pure caffeine powders. Chris Holstege and other experts discuss the health concerns and associated risks of using caffeine powder with WebMD.

As reported by The St. Louis American, Pui-Ling “Melissa” Chan has won the Southern Illinois University Edwardsville’s 2014 Vaughnie Lindsay New Investigator Award. The award is presented annually to a tenure-track faculty member making significant contributions in his/her field of study and to the university.

To mark her 100th birthday, the contributions of honorary member Frances Oldham Kelsey to public health were featured in FDA Voice. Dr. Kelsey is responsible for protecting American mothers and babies in the 1950s from the sedative thalidomide.
