Scientists Invent Light-Activated Bio-Glue That Stops Bleeding In Seconds (cnn.com) 74

Posted by BeauHD from the new-and-improved-medicine dept.
hackingbear shares a report from CNN: A team of researchers from Zhejiang University School of Medicine in Hangzhou, China, created a gel composed of a network of proteins, inspired by the matrix composition of human connective tissues, and other molecules. The product, which requires ultraviolet light to activate, can adhere within seconds and then bond to wet biological tissue surfaces without suturing. In pigs, the bio-glue sealed a punctured carotid artery, a major blood vessel in the neck, in less than a minute and also filled holes in the cardiac wall. The Chinese researchers monitored their post-surgical pigs for a two-week recovery period and saw natural healing with no abnormalities or unusual inflammation. Around the globe, more than 234 million surgeries are performed each year, the World Health Organization estimates. Additional research confirming the safety of this product is needed before experiments can begin in humans, according to the authors of a study published Wednesday in the journal Nature Communications.

  • I woke up this morning and checked out what's going down on Slashdot. And here I see three stories referencing how China [slashdot.org] is transforming [slashdot.org] science [slashdot.org]. And all I can think is...Good for them.

    I know a lot of Americans want to believe that the United States is the hero of the world. But I believe that anything any world citizen can do to help us grow as a human species is a rising tide that lifts all boats.

    • Nobody is speaking ill of China or its accomplishments. The only trolling here is coming from the Trump Derangement Syndrome crowd.
    • How's your social score rating? Not high enough, sorry, bum. You ain't in a boat, so the rising tide is only going to drown you. That's the future.

      Probably based on Kodak's research from 1942, Cyanoacrylates, aka "superglue". Field tested by US Army medics in Vietnam in the 1960s. Unless it based on more recent US based or funded research. Its not like there is any shortage of articles about employees of US companies and researchers at US universities sending information "home to China". Or related to a forced technology transfer to operate in China. Yeah its completely unfounded to be suspicious huh?

    [ And wouldn't a blood-activated bio-glue make more sense? Just sayin' ...]

  • Same tech has been used for eye surgeries (Score:3)

    This same technique is common for eye surgeries. Last year I accompanied a close friend who had cross-linking treatment [wikipedia.org] for keratoconus [wikipedia.org], a condition that causes of the cornea to progressively become more cone shaped.

    This procedure is apparently common in Europe, and recently was approved for use in the U.S.

    Emergency uses of this in the field could be quite beneficial. Bleeding from gunshot wounds or major car accidents could be stopped quickly in the field and then better managed in the hospital. Since it is a protein matrix, it wouldn't cause tissue damage like staples or other devices to try and stop bleeding. Here's hoping it continues to be developed and find uses in and out of the hospital.
    • The US Army was using "superglue" in Vietnam. It is credited with saving many lives. The original formula caused skin irritation in some, there was research to reformulate it to reduce this side effect. Such problems prevented FDA approval but for battlefield medicine it was incredible. Not sure what the modern "field expediency" is.
  • Notice to America : In order to be first you actually must be first. Claiming that you are the most advanced will not work in the information age unless you really are first. Not only are universities in China and other nations that appear exotic to us doing great work but here in the US when you see credits for major breakthroughes in science, medicine and electronics you will see the faces of research scientists from China and other Pacific nations but also India and Pakistan frequently be depar
