New research on how treefrogs protect their cells during freezing

  Brian Stogsdill, Jim Frisbee and Dr. David Goldstein at Wright State University discussed their research at the 34th annual Ohio Physiological Society meeting on special water channels in the red blood cells of freeze-tolerant Cope’s gray treefrogs. These channels can shuttle both water and glycerol in and out of the cells to protect them from damage during freezing. Check out this video showing a treefrog waking up from a […]

Improving tissue integrity for transplants

Ground squirrels are known for their remarkable ability to tolerate hypothermic conditions. Humans are not. Dr. JingXing Ou (National Institutes of Health) presented an interesting talk that explored using induced pluripotent neuronal stem cells isolated from these mammalian hibernators to improve tissue integrity for organ transplants. By understanding which pathways protected ground squirrel cells from cold-damage, these pathways could be manipulated in human induced pluripotent neuronal stem cells and improve […]

Ohio is talking about fixing broken hearts, the physiology of freezing, combating opioid addiction and more

The Ohio Physiological Society held their 33rd¬†Annual Meeting at the¬†University of Cincinnati this weekend. The keynote address was given by Dr. Mark Sussman from San Diego State University. He spoke about current research strategies that aim to improve the ability for the heart to repair itself after heart failure. Dr. Perwez Alam (University of Cincinnati) also spoke about using siRNA to try to repair heart tissue after heart attacks and […]
