EB 2022: Seals, seals, and more seals

Several posters at EB 2022 in Philadelphia this month were focused on understanding the remarkable physiology of diving seals. Although we may think of the image below when we picture seals, they really are quite the athletes in water. Kaitlin Allen (a graduate student working in the laboratory of Dr. José Pablo Vázquez-Medina at the University of California Berkeley) presented her research on Northern elephant seals and how these animals […]

Physiology in Arizona – Part 1

This past weekend the Arizona Physiological Society held their 11th annual conference on the Tempe campus of Arizona State University. There were so many oral and poster presentations on comparative physiology that I will spend this entry focusing on the oral sessions. The Keynote address was given by Dr. Michael Joyner (Mayo Clinic, Rochester) who spoke about the importance of not just focusing research efforts on reductionist approaches, including many […]

Seals have anti-inflammatory blood

Dr. Allyson Hindle from Massachusetts General Hospital in Boston, presented some interesting research on seals at the Experimental Biology conference this week in San Diego. Seals are known for being rather plump, which for humans often leads to inflammation and cardiovascular disease. In addition, seals undergo repeated bouts of hypoxia and reoxygenation during their dives, which is also known to promote inflammation and cardiovascular disease in humans. Her research team […]

Drug increases blood flow to the brain – Implications for stroke?

Researchers from Friedrich Schiller University (Jena, Germany) and Heinrich-Heine-University (Düsseldorf, Germany) teamed up to test whether a heart failure medication that is currently being tested might also improve blood flow in the brain. Their findings were published last month in the American Journal of Physiology, Heart and Circulatory Physiology. According to the study authors, the small blood vessels in the brains of sheep closely resemble those in the human brain. Using imaging techniques, they […]
