Gut-temperature axis in high altitude deer mice?

Dr. Graham Scott (McMaster University) presented intriguing research at the American Physiology Summit earlier this month in Long Beach, CA. His laboratory has been examining a potential link between the gut microbiome and the ability for deer mice to help regulate body temperature. Deer mice live in high elevations where atmospheric oxygen levels are low. This presents a physiological challenge as they have to use a lot of energy to […]

Flexible hypoxia tolerance in frogs

In a new study published in The Journal of Neuroscience and presented at the American Physiology Summit earlier this month, graduate student Nikolaus Bueschke, postdoctoral fellow Dr. Lara Amaral-Silva and Dr. Joseph Santin (University of Missouri, Columbia) together with researchers Min Hu and Alvaro Alvarez (University of North Carolina at Greensboro), explored how bullfrogs (Lithobates catesbeianus) emerging from hibernation tolerate hypoxia while they kickstart physiological functions in ice-covered ponds. This […]

Physiology on the road: What’s happening in Arizona

The Arizona Physiological Society held their 16th annual meeting this past weekend at Midwestern University in Glendale, Arizona. The Arizona Established Scientist Keynote Speaker was Dr. Christopher Glembotski, Professor of Internal Medicine and Director of the Translational Cardiovascular Research Center at the University of Arizona, Phoenix campus. Ischemic diseases, such as strokes and heart attacks, disrupt the normal functioning of the endoplasmic reticulum, which alters protein production and folding. His […]

Physiology on the Road: What’s happening in the Midlands

The Midlands Society of Physiological Sciences held their annual conference on October 21st at the University of Nebraska Medical Center. The Keynote Lecture was given by Dr. Manolis Kellis, Professor at Massachusetts Institute of Technology. He spoke about the use of artificial intelligence approaches to examine how fly and human genes are regulated. Other highlights: Anuj Singh (University of Nebraska Medical Center): Opioid use is a major healthcare concern and […]

Physiology on the Road: “Physiology in Ohio, The Heart of it All!”

The Ohio Physiological Society met October 6-7th at The University of Toledo located in Toledo, OH. True to the name of this year’s conference, the Keynote address was given by Dr. Joseph Wu, Director of the Stanford Cardiovascular Institute and current president of the American Heart Association. His research focuses on congenital heart disease in adults as well as cardiovascular imaging. His most recent clinical trials involve testing bone-derived stem […]

Physiology on the road: What’s happening in Missouri

This time of year is perfect for catching up on local physiology news. For the next few posts, we are going to take a tour around the country to learn what’s going on in some of the chapters of the American Physiological Society… First stop: the Missouri Physiological Society, otherwise known as “mophys”. Mophys is an independent chapter of the American Physiological Society. They held their annual meeting on September […]

Meet the monkeyface prickleback (that is not a typo):

Someone must have seen a resemblance to monkeys when naming these animals. Adult monkeyface pricklebacks, Cebidichthys violaceus, weigh around 6 pounds and can grow up to 2.5 feet long. They can live up to about 18 years of age. Despite their appearance, they are not eels, although their eel-like shape allows them to hide in crevices. They are native to the California coast and their home range is only a […]

Cardioprotective adaptations to high altitude

While studies have shown that Tibetans protect their tissues from damage caused by low oxygen levels at high altitude, other studies have shown that people adapted to life in the Andes mountains have genetic variations that protect their hearts. In a recent study presented at the 2023 American Physiology Summit, scientists discovered that 68% of Andean highlanders carry a single nucleotide variation in the gene responsible for encoding the protein […]
