Dr. Liz Phular and colleagues at the University of Minnesota have been testing an experimental cancer treatment for brain tumors in dogs that also offers hope to humans with brain tumors: KMSP-TV

Experimental Biology – Sunday

The Comparative and Evolutionary Physiology section held their Scholander Poster competition for young comparative physiologists today! It was exciting to see all of the students present their work. Here are some of the highlights: Raffaele Pilla, Dominic P, D’Agostino, Carol S. Landon, and Jay B. Dean from Molecular Pharmacology and Physiology, University of South Florida, Tampa, FL.…

  You may recall a prior blog entry about a new experimental treatment for bone cancer in dogs. Researchers are increasingly studying canine cancer and discovering that it is caused by some of the same genetic mutations that cause cancer in humans.   Shown in the image above is Jasper, a 7-year old dog that has lymphoma,…

African rodent species resist scarring

You might be familiar with tissue regeneration in amphibians and reptiles where limbs can be fully regenerated following an injury. Until now, tissue regeneration following a wound was thought to be limited in mammals (ex: deer shed and regrow their antlers annually; some mice can regrow the tips of their fingers). Researchers discovered that African…

Researchers Sanchez et al. from the Gladstone Institute, University of California San Franciso and Washington University School of Medicine discovered that an FDA-approved anti-convulsant medication used to treat epilepsy (levetiracetam) can also reverse memory loss in addition to reducing other Alzheimer’s related symptoms in a mouse model of the disease. Alzheimer’s is currently the most common form of…

Life-saving microparticles

Scientists have been able to keep rabbits alive for up to 15 minutes after their windpipes had been blocked by injecting microparticles (yellow in the image below) containing oxygen into their bloodstream.  These microparticles are able to deliver the life-saving oxygen directly to red blood cells allowing the animals to survive with normal blood pressure and heart rates in…

Butterfly Antifungal

Photo: KENPEI, Wikimedia Commons. Researchers have isolated an antimicrobial peptide from swallowtail butterflies, Papilio xuthus (image above). After creating a synthesized version of the peptide they called Papiliocin, they wanted to know how it worked. What they found was that Papiliocin causes yeast cells (Candida albicans) to accumulate reactive oxygen species, which triggers a process…
