New research published in the American Journal of Physiology Regulatory, Integrative and Comparative Physiology shows that bacterial infections increase the production of nitric oxide in chicks, which is similar to what happens in rodents. The increase in nitric oxide is thought to be related to the development of fever. In fact, when nitric oxide production was blocked,…

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…

Check out this picture of a cigar

Most people just see a horizontally oriented cigar (brown with grey ash) when they look at the picture below, but if you look closely you can also see what looks like a wall of red bricks behind the cigar! Yet another view:

I am very excited about the upcoming 3rd annual Michigan Physiological Society Meeting on May 12-13 in Detroit. This society is a local chapter of the American Physiological Society. I am most excited by their choice of a Comparative Physiologist for the keynote address: Dr. Hannah V. Carey from the University of Wisconsin School of Veterinary…

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…

This year’s August Krogh Distinguished lecture, the highest award given to an accomplished Comparative Physiologist from the Comparative and Evolutionary Physiology section of the American Physiological Society was awarded to Dr. Jon Harrison, Arizona State University. Dr. Harrison gave an outstanding seminar in which he reviewed some of his major research discoveries. His work has…

Still going strong…here are the highlights from several sessions held on Day 4: John Eme (California State University, San Marcos) presented data testing the effects of varying temperatures mimicking overwintering conditions on embryonic development of Lake whitefish. He found that indeed exposure to variable incubation temperatures between 2-8 deg C resulted in increased mortality. Moreover, the embryos hatched…

I LOVE THIS MEETING! DAY 3 included several very interesting comparative physiology sessions. Eldon Braun (University of Arizona) spoke about how birds have a unique way to prevent water loss and thereby dehydration. In mammals, the kidneys are responsible for recovering water from the urine. However when birds are well-hydrated, the urine enters the colon…
