kidney
dr. dolittle | May 15, 2017Have you ever heard of 'Goodpasture Syndrome'? I'll admit I haven't. Check out the award-winning video below for the 2017 American Physiological Society's video contest to learn about this syndrome. The video was created by Melissa Traver, Samantha Lyons, and Andrianna Walsh from Centenary College of Louisiana. Congratulations!!

Seawater contains sulfate concentrations that are nearly 40 times those measured in plasma. Therefore, it is easy to see why fish would need to develop mechanisms to keep sulfate within a physiologically normal range. The kidneys of teleost fish have been known to excrete excess sulfate in the urine. However until now, it was not known whether the kidneys of cartilaginous fish do the same thing as their kidneys are rather…
dr. dolittle | August 3, 2015I came across this neat video from Mayo Clinic researcher Dr. Michael Romero, a comparative physiologist interested in how the kidneys work. In this video he describes discoveries made in zebrafish that relate to human kidney function:
dr. dolittle | April 15, 2013Researchers at Massachusetts General Hospital (Boston) have successfully regenerated kidneys that were unsuitable for transplantation. They stripped the tissue of all native cells, then added donor stem cells to the scaffolding that was left behind. The re-animated kidneys successfully created urine after being transplanted into rats! The hope is to apply this technique to humans with end stage renal disease who are in need of kidney transplants and reportedly would work for the regeneration of other tissues as well.
