Exosomes promote remarkable recovery in stroke

Exosome crystal structureIt’s been almost a quarter century since the first drug was approved for stroke. But what’s even more striking is that only a single drug remains approved today.

In a publication appearing this month in the journal Translational Stroke Research, animal scientists, funded by the National Institutes of Health, present brain-imaging data for a new stroke treatment that supported full recovery in swine, modeled with the same pattern of neurodegeneration as seen in humans with severe stroke…

Trauma from an acute stroke can happen quickly and can cause irreversible damage almost immediately…In less than 60 seconds, warns the Stroke Awareness Foundation, an ischemic stroke kills 1.9 million brain cells….

“Basically, during a stroke, these really destructive free radicals are all over the place destroying things,” said Stice, director of the RBC. “What the exosome technology does is communicate with jeopardized cells and work like an anti-inflammatory agent to interrupt and stop further damage.”


Endless possibilities for genetic engineering, environmental ameliorations, drug development…

As a society, we face various issues in the modern world. Synthetic biology is an emerging field that is attempting to address these problems at the genetic level, and researchers in this field are pushing the boundaries of which proteins and processes can be developed and utilized.

One of the latest pieces of research to be undertaken is the invention of semi-synthetic organisms. But what is a semi-synthetic organism?

A semi-synthetic organism is a genetically modified organism (usually a bacterium such as E. Coli), which has had unnatural genetic information inserted into its genome. Read more...

...and every living creature that moveth, which the waters brought forth abundantly, after their kind, and every winged fowl after his kind ... the living creature after his kind, cattle, and creeping thing, and beast of the earth after his kind ...the beast of the earth after his kind, and cattle after their kind, and every thing that creepeth upon the earth after his kind: and God saw that it was good. -Genesis 1

Flesh and Bone and The Protestant Conscience is an e-book on It is 99¢ and in the Amazon lending library as well. It is also available here in PDF format. The book description follows.

Would you let your conscience be your guide?

Does God care if the skin and bone of the dead are passed along to the living for medical uses? Is organ donation OK with God? Should you sign a Living Will?

Did you know that dead organ donors are often anesthetized before their organs are removed? Do you know the current definition of death? The conscience cannot function without facts.

As we ponder the ethics of in vitro fertilization, stem cell research and man-made chimeras, our thoughts trail off. How then should we live? (Ez 33:10)

How should a Christian think about euthanasia by starvation when doctors and the state attorney general all agree it is time to withhold feeding from a brain injured patient? Some things are family matters, but someday it may be our family.

Here is a small book to help you think about whether you want to sign your driver's license, donate a kidney, cremate your loved one, and many other practical questions that may arise in the course of your healthcare decisions or watch over others.

It offers a special focus on the doctrine of the Resurrection that is related to such decisions. Sunday School classes and Bible Study groups could use this book to facilitate discussion about the issues covered.
