Research for Back Pain Relief Strikes Gold

...pinning, she evolved a series of ‘’bioresorbable’’ polymer scaffolds. These scaffolds when surgically implanted are to hold tissues together hastening cell repair and regeneration. Bioresorbable scaffolding, which in due time dissolves is beneficial to patients in the long run as they hasten the healing proc...

Multiple deaths forces cancer trial to be called off

...a regularly used chemotherapy agent coupled with a polymer which is supposed to help in making the it more user friendly. The same drug in previous tests conducted last year failed to prove itself in improving survival rates in general but showed significant benefits among women. The company has announced t...

Hope For Patients With Macular Degeneration From Manmade Protein

...cancers. They also are looking at a biodegradable polymer cage so they can encapsulate the intraceptor, tag it with a homing device for target cells and deliver it 'like a missile carrying a payload' into the desired cells where it will slowly release the intraceptor, he says. Co-authors include Dr. Nirbha...

Athletic Gear in Youth Not Protective Against Near Fatal Blows to chest

...ard, commercially available chest barriers made of polymer foam covered by fabric or a hard shell. In addition research conducted at the New England Medical Center and Tufts University School of Medicine in Boston revealed that ventricular fibrillation could be caused by a baseball moving 30 mph (48 kph), ...

Gene Discovered by Researchers Tied to Pancreatic Cancer

... cells, specifically via the actin cytoskeleton, a polymer protein complex that provides much of the basis for cell shape,” Otey said. In 1996 Dr. Teresa A. Brentnall, an associate professor of medicine at the University of Washington, became aware of a family in which 18 members, over four generations, di...

MIT Creates 3-D Scaffold for Growing Stem Cells

... the authors wrote in the paper. Other synthetic polymer biomaterials are simply too big. Getting cells to grow on them is like forcing spiders to build webs on skyscraper girders. Zhang's nanofiber scaffold, around 1,000 times smaller than the existing systems, is much closer in size to the extracellular ...

A Laboratory Filtration System Kills 100 Percent Of Dangerous Microbes In Water

...m that the researchers are developing is simple: a polymer sheet of resins containing copper is immersed in the contaminated flood water. The addition of hydrogen peroxide generates free radicals on the polymer. The free radicals remain bound to the sheet, where they come in contact with bacteria and kill th...

Humble Cold to Combat Cancer

... viruses, or coating these viral ‘soldiers’ with a polymer coat, or it so that could escape attack from the immune system. Seymour calls this new adaptation of the virus as ‘stealth virus’, meaning they are masked to escape detection. Seymour hopes to turn the strength of tumor into its weakness by us...

Nanoparticle Research Offers Hope of Artificial Retinas, Prostheses

... nanoparticles and another of a positively charged polymer called PDDA. The scientists then added a layer of ordinary clay and a cell-friendly coating of amino acid, and placed cultured neurons on the very top. When light shines on them, the mercury-tellurium nanoparticle film layers produce electrons, whi...

A New Inexpensive Technology for Multiplexed Detection

... are also unique in that they are made of a spongy polymer "hydrogel" called poly(ethylene glycol). That polymer enhances the sensitivity of the test because it is porous, allowing the target molecules to diffuse ...

Artificial Vein to Boost Surgery and Ease Patient Trauma

...ion. The artificial vein has been created from a polymer called ePTFE. It is grooved on the inside akin to a gun barrel, which Stonebridge says encourages the spiraling flow of blood. He lists other advantages as reduced wear and tear of the device, lesser chances of clogging and aid in the removal of...

A New Test Kit to Detect Spoilt Food

...biogenic amines. In lab studies, they tested these polymer biosensors against a variety of fish samples, including fresh salmon, fresh tuna and canned tuna. The polymers change color in the presence of increasing levels of these biogenic amines to indicate degrees of food spoilage. Specifically, the polyme...

Scientists Create Fire-proof, Eco-friendly Plastic

Scientists have created a synthetic polymer that doesnt burn, making it an attractive alternat...sometimes referred to as solid gasoline. The new polymer wouldnt need the flame-retardant chemicals that are added to many plastics before they can be used i...

Bubbles may Pave Way for Producing Nanoscale Electronic Components

... US, used nitrogen gas to blow bubbles of an epoxy polymer containing silicon nanowires and caught the resulting film on a surface. Then they examined the resulting film under both optical and electron microscopes, and found that the nanowires and nanotubes had become neatly lined up vertically towards the...

Nanomedicine Gives the Way for Nerve Cell Regeneration

...material is composed entirely of aligned nanoscale polymer fibers. These polymer fibers act as physical guides for regenerating nerve fibers. They have also developed a way to mak...

Scientists Develop Artificial Blood Vessels for Vascular Grafts in Mice

...re was an extensive remodelling of the MDSC-seeded polymer by surrounding tissue, exhibiting tissue formation that is consistent with a mature artery. Dr. Vorp says that the new findings demonstrate the feasibility of developing MDSC-seeded tissue-engineered vascular grafts for eventual human application. ...

Lobster Shells Have Great Healing and Antiseptic Properties

...nd germination in seeds. Chitin is a very common polymer present in nature as part of animals and plants physical structures. Only cellulose is more abundant than chitin, which makes this compound a highly important renewable resource that can easily be found in arthropods, insects, arachnids, molluscs, fu...
