As we get older, the cushy material that absorbs shock between our spinal vertebrae breaks down, creating back pain and inhibiting our mobility. Injections of more nucleus pulposus (NP) cells--the jelly-like tissue found between spinal discs--have been shown to delay this degeneration and relieve pain, but with current methods, the injected cells leak away from the injection site within only a few days.
A new biomaterial created by Duke University biomedical engineers could make cell therapy a more feasible solution to spinal disc degeneration and back pain by keeping those cells in place for longer. The material starts out as an easy-to-inject liquid, then solidifies into a gel, holding more of the NP cells where they're needed. When it stays at the injection site between the spinal discs, the biomaterial helps distribute pressure and improve spine mobility.
The gel forms when three liquid components mix together. In preliminary testing with rats, the liquid began to solidify after five minutes, and set after 20. The researchers think one of the liquid components, a chemically-modified protein called laminin that's found in healthy discs, might help the NP cells survive longer and stop degeneration.
The study appears online in Biomaterials.
First yes this will be given to those in need medically speaking, but later it will be given to jet pilots for the purpose of enhancing a higher tolerance of G-force!
Will it give those pilots the virtually unlimited resistance to G-forces which drones enjoy? If not, get in the jobs line with the coopers and wheel wrights fly boy, your days are numbered.
If one experiences the pain and depression associated with spinal problems, they will jump at anything with a promise of relief. How'd that work out for those women desperate for silicon breast implants? This looks fantastic, but you go first everybody.
The women "desperate" for silicone (note spelling, siliCONE, not siliCON--if you're going to snark, try to not show off your ignorance) were, for the most part, not trying to deal with a medical condition. Of course, feel free to equate debilitating spinal soft tissue conditions with mere self-centered vanity. In addition, silicone is an entirely synthetic material that had no antecedents in the human body. This gel is based on laminin and PEG. Laminin is a natural human protein. Unlike silicone for breat implants, while PEG is synthetic, it has already had decades of study for both acute and chronic effects. In addition, unlike silicone, PEG can be (and probably is meant to be in this application) eliminated from the body, ostensibly as regrown disk tissue replaces the biogel.
It only a matter of time when a uneducated person fly's to a south American country and visit a unlicensed doctor for a miracle cure for their pain torturous back problems to be shot up with 'fix a flat'!
Spine is not the problem with G forces...The problem is that g forces, acting downward, pull blood from the brain and the pilot either greys out out passes out.
