Muscle Aging in American Quarter horses

Skeletal muscle function and structure change as we age. Humans typically experience a loss of muscle mass or muscle weakness which can greatly reduce mobility and stability. While much is known about aging skeletal muscle in humans and rodents, less is known about horses, which are rather athletic animals that are living longer due to advancements in veterinary care and retirement programs. Researchers from the University of Florida decided to explore how aging effects skeletal […]

Recap of 2016 Michigan Physiological Society

The Michigan Physiological Society, a chapter of the American Physiological Society, held their 3rd annual meeting last week. As mentioned in a prior post, the keynote address was given by Comparative Physiologist Dr. Hannah Carey (University of Wisconsin School of Veterinary Medicine). You can read about her research in the prior post. Here are other highlights from the meeting: Seminars: or as I prefer to view them… Kelsy Kusch (Undergraduate Student, […]

Experimental Biology – Day 5

Today was the final day of the meeting. Dr. Joe Thompson (Franklin and Marshall College) spoke about oblique striated muscles, which get their name from the diagonal pattern formed by the location of the Z-lines. This type of muscle is common among cephalopods, nematodes, tunicates, molluscs, etc. Dr. John Whiteman (University of Wyoming) gave a fascinating talk about polar bears and whether hunting on the shore as compared to the sea […]

Heat stress in livestock

With the approach of summer, a timely study was published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology on whether inflammation plays a role in heat stress-related complications in muscles. Heat stress is a major problem in the livestock industry. In the United States alone it is reportedly associated with a loss of approximately $158 billion annually in the swine industry. To cool off, swine seek shade and often mud baths […]
