Episode 7 Nanoparticles and Disease

cguilfoy@the-aps.org (The American Physiological Society) — Mon, 31 Mar 2008 14:13:00 GMT

This is a re-issue of Episode 7!

Nanoparticles, which are 1,000 times smaller than a bacterium, are being manufactured and incorporated into some commercial products such as cosmetics and clothing. While nanotechnology holds promise, there is little understanding of how these super small particles might affect us if they get inside our bodies.

Two researchers from the Mayo Clinic College of Medicine will tell us about their research investigating the role these particles might play in disease. John Lieske will talk about his research on the role one nanoparticle may play in the development of kidney stones. And Virginia Miller will tell us about her work on a nanoparticle that may play a role in hardening of the arteries.

Drs. Lieske and Miller will lead a symposium on this topic at the Experimental Biology Conference on Wednesday, April 8.

The theme music you hear at the beginning and end of the show, Body Notes, was composed by APS member Hector Rasgado-Flores and was performed by the San Diego Chamber Orchestra.

Episode 6: The Mystery of Serotonin & Hypertension

cguilfoy@the-aps.org (The American Physiological Society) — Tue, 18 Mar 2008 18:06:00 GMT

We continue our coverage of Experimental Biology 2008 with an interview with Michigan State University Professor Stephanie W. Watts, who has been investigating whether serotonin plays a role in high blood pressure.

The APS has awarded Dr. Watts the Henry Pickering Bowditch Memorial Award for early-career achievement. The award goes to a scientist younger than 42 years whose accomplishments are original and outstanding. It is the Society's second-highest award.

The theme music that you hear at the beginning and end of the program, Body Notes, was composed by APS member Hector Rasgado-Flores and performed by the San Diego Chamber Orchestra.
