... The genetically engineered proteins combine pieces of two proteins that are normally present on the surface of the bacterium that causes Lyme disease, but at different parts of the organisms life cycle. "Combining pieces of these two proteins into one chimeric protein shou...Researcher examines polymers created with poultry feathers
... According to the U.S. Environmental Protection Agency, more than 29 million tons of non-biodegradable plastic waste ends up in landfills each year. Justin Barone, associate professor of biological systems engineering at Virginia Tech, is investigating ways to create biodegradable plastics from agricultural byproducts such as poultry feathers and eggs that would be comparable to petroleum-ba...Polymers show promise for gene delivery, tissue scaffolds, other biomedical applications

In the United States, Lyme disease incidence has skyrocketed from 497 cases reported in 1982 (the first year national statistics were collected) to a record 23,763 in 2002. Lyme disease, like other zoonoses, is transmitted by a vector that picks up the pathogen during a blood meal from a vertebrate host. In the eastern and central United States, the spirochete bacterium Borrelia burgdorferi inf...Stable polymer nanotubes may have a biotech future
Scientists at the National Institute of Standards and Technology (NIST) have created polymer nanotubes that are unusually long (about 1 centimeter) as well as stable enough to maintain their shape indefinitely. Described in a new paper in Proceedings of the National Academy of Sciences,* the NIST nanotubes may have biotechnology applications as channels for tiny volumes of chemicals in nanofluidi...Polymer aids in blood clotting, pointing way to new treatment
A serendipitous comparison prompted by an old scientific image and involving an ancient but understudied molecule may lead to a new treatment strategy for injuries or illnesses in which blood clotting is paramount to survival....... In a paper to be published in the Proceedings of the National Academy of Sciences, researchers from the University of Illinois at Urbana-Champaign and the University...Polymer gel can block toxic leakage problem in gene therapy
DURHAM, N.C. -- Duke University biomedical engineers have devised a potentially patentable method to arrest toxic leakages of genetically engineered viruses that have plagued attempts to use gene therapy against cancerous tumors. The problem has been that viruses carrying anti-tumor genes have tended to leak from tumors, proving toxic to other body tissues....... The researchers have developed a...New U. of Colorado polymer has applications for dentistry, electronics, automobiles
University of Colorado at Boulder researchers have developed a new polymer that resists cracking and shrinking, paving the way for creative breakthroughs in fields ranging from dentistry and microelectronics to the auto industry. ... ...

US Public Health Service, National Institutes of DALLAS April 25, 2005 When the tick-borne bacterium that causes Lyme disease lacks a specific protein that responds to an incoming meal of blood, it is unable to be transmitted from the tick to a new animal host, researchers at UT Southwestern Medical Center have found. ... The findings suggest that the protein, called BptA, is essential for the...New gas sensors patterned with conducting polymer
An improved method for depositing nanoporous, conducting polymer films on miniaturized device features has been demonstrated by researchers at the National Institute of Standards and Technology (NIST). ...... Described in the April 6 issue of the Journal of the American Chemical Society,* the method may be useful as a general technique for reproducibly fabricating microdevices such as sensors for...Polymers with copper show promise for implanted sensors
ANN ARBOR, Mich.---Developing chemical sensors that can be placed in the bloodstream or under the skin to continuously monitor oxygen, acidity (pH), or glucose levels is a major challenge for analytical chemists and biomedical engineers. The problem is, the body responds to these foreign objects in ways that interfere with their ability to accurately measure blood chemistry.
