Why do we feel sleepy after a big Thanksgiving meal? Is there something in the turkey? Are cranberries good for our kidneys? These are two of the questions our experts will explore. Chris I. Cheeseman of the University of Alberta will talk about tryptophan in turkey. (Begins at 3:17.) L. Lee Hamm of Tulane University School of Medicine will discuss what the research shows about cranberries and kidney health. (Begins at 8:58)

Kevin Heffernan (13:26) will talk about his study, aimed at trying to uncover why African-American men have a higher rate of hypertension than white men. The research team from the University of Illinois, Urbana Champaign, found some early signs of vascular damage in young, healthy African-American men and found that measuring central blood pressure may be a better way of identifying those at risk.

Segment 1: What a Gas.  University of Alabama – Birmingham researchers Jeannette Doeller and David Kraus talk about the amazing properties of hydrogen sulfide gas. Although it’s lethal in even minute quantities, our bodies produce it and use it to good effect. Episode 10 graphic courtesy of David Kraus. Begins at 1:15.

Segment 1: Warm body, cold heart: Barbara Block of Stanford University talks about her research with the bluefin tuna, one of the few fish species to have a warm body. You can see how marine animals are being tracked by going to www.topp.org.

Segment 2: Longer, deeper: Andreas Fahlman of the University of British Columbia Marine Mammal Research Unit in Vancouver and Global Diving Research in Ontario explains the physiology that allows mammals such as sea lions to dive so much deeper and for such a long time, compared to humans. You can find a video showing the work of Dr. Fahlman and his colleagues at www.marinemammal.org/2007/fahlman.php and more is available at www.marinemammal.org/MMRU/.

Jay B. Dean, a professor at the University of South Florida, discusses the aviation research that physiologists did during World War II. This research helped the Allies win the Air War. Dr. Dean has prepared a presentation on this topic for the Experimental Biology conference taking place in San Diego, April 5-9.

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.
