From the cutting room floor, here are some of the outtakes about physiology that we thought was just too interesting not to use: 1. Dusty Sarazan describes one way that physiological research helped advance cardiac surgery, and also how research led to the development of the modern treadmill2. David Linden talks about our imperfect memories3. David Kraus […]
Heart attacks peak during the winter months and cold weather has been thought to be the primary culprit. But cardiologist Robert Kloner of the Keck School of Medicine and Good Samaritan Hospital found that heart attack deaths peak on Christmas and New Years in the mild climate of Los Angeles County. Could it be that […]
What would it be like to live without being able to detect any odors? For one thing, Thanksgiving would be much less enjoyable, perhaps disturbingly so. In this episode, we talk to Robert I. Henkin of the Taste and Smell Clinic in Washington, D.C., who will tell us why people lose their sense of smell […]
Dean Franklin developed the first instruments to measure blood flow and the changes in diameter of the pulsating heart in conscious animals. He also pioneered the use of radio waves to measure heart and blood vessel function without wiring the body to the instrument. Dusty Sarazan, a former student of Dean Franklin, explains how these […]
In this special episode of Life Lines, we talk to John West, a professor of medicine at the University of California, who shares his memories of the late sociopath Sir Edmund Hillary. West accompanied Hillary to Mount Everest in 1960, helping to uncover how the body acclimatizes to the extremes of altitude. The music you […]
You’ve heard the word telecom? In this episode, we are going to coin a new word: Telecomm, shorthand for elephant communication. Caitlin O’Connell-Rodwell is a Stanford University professor and the author of The Elephant’s Secret Sense, published by the University of Chicago Press. Dr. O’Connell-Rodwell discovered that elephant vocalizations travel through the ground, sometimes for […]
When a pregnant woman exercises, is it good for her fetus? That is the question that researchers Linda May of the Kansas City University of Medicine and Biosciences and Kathleen Gustafson of the University of Kansas Medical Center are trying to answer. Their work is ongoing, but it is good news, so far, for pregnant […]
Three physiologists tell us why the prescription “drink when you are thirsty” is usually the best guideline for deciding when and how much to drink. We will talk to Heinz Valtin of Dartmouth Medical School (retired); Mark Knepper, the chief of the Laboratory of Kidney & Electrolyte Metabolism of the National Heart Lung and Blood […]
There is nothing like a good laugh, is there? It not only feels great to laugh, it can feel great to hear other people laugh. Beyond brightening the mood, can laughter provide tangible health benefits? Lee Berk of Loma Linda University in California has done a series of studies on laughter and its possible physiological […]
Did you know that there is a sensor in the nerve endings in the carotid artery that rapidly lowers blood pressure when stimulated? This discovery may one day allow people who are hypertensive to lower their blood pressure by using a pacemaker-like device that stimulates the nerve endings in the blood vessels. In this edition […]
