Daily Haiku / Senryu : Elastic

new elastic glue
clinical testing is next
internal wounds healed

         Senryu by M. Nakazato LaFreniere

Love it when people work together to make something cool. Researchers in the Northeastern United States and Sydney, Australia have created a new elastic protein-based gel which can be injected to seal internal wounds in a minute.  Ultra-violet lights set the glue.

Based on methacryloyl-substituted tropoelastin, a hybrid elastic protein, the gel is called MeTro for short.  Elastin is highly elastic human protein which allows tissue to stretch and shrink without coming apart like our lungs, heart, bladder and skin.  The body makes elastin by linking molecules of precurser protein Tropoelastin.  So this gel mimics the bodies natural abilities to stretch and contract even as it closes a wound.  They can even set duration the gel will last before it dissolves back into the body.

So far the glue has only been tested on rats and pigs.  Next step is clinical testing on humans. The scientists see many applications of this new gel including being able to treat folks with serious internal wounds at the emergency site and eliminating sutures and and staples in lung and other surgeries.

Let’s not forget, for every one destructive person creating chaos for hours, there are thousands out there working, spending their days, years and decades to make things better. These lives are often quiet; no headline splashes for them.  But in the long run, they are the ones that matter. Their changes will be built upon from others and silently or with fanfare integrated into society.

Here’s a toast to the good that people strive for.
