Tracking how steroid hormone receptor proteins evolved

When thinking about the evolution of female and male, consider that the first steroid receptor proteins, which emerged about 550 million years ago, were responsive to estrogen. The ancestor of other steroid hormone receptors, responsive to hormones such as testosterone, progesterone and cortisol, emerged many millions of years later. Biochemist Eric Ortlund and colleagues have a new paper in Structure that reconstructs how interactions of steroid receptor proteins evolved over time. This is a complex Read more

CPR Manikins Make Training Easier

Studies have consistently found that cardiopulmonary resuscitation (CPR) performed immediately by a bystander doubles or even triples a cardiac arrest victim’s chance of survival.

To increase the rate of bystander CPR, the American Heart Association recently modified its CPR guidelines so that it is now permissible to provide continual chest compressions without mouth-to-mouth rescue breathing. This makes CPR easier and may even produce better results.

Arthur Kellermann, MD, MPH

Arthur Kellermann, MD, MPH, formerly an emergency medicine physician and associate dean for public policy at Emory, and David Sanborn, a mechanical engineer at Georgia Tech, have invented a low-cost CPR manikin to help anyone learn and practice compression-only CPR. Kellermann currently is director of the Program in Public Health Systems and Preparedness and Paul O’Neill-Alcoa Chair in Policy Analysis at the RAND Corporation in Virginia.

Their work builds on Emory research that showed laypeople could teach themselves CPR at home using a 25-minute video with results that are comparable to taking a four-hour course taught by a professional instructor.
