Collaborative research initiative aims to cut drug development time in half

...earch on various aspects of myelin--the protective coating surrounding the nerve fibers of the brain and spinal cord. This innovative approach to medical research breaks down traditional barriers to collaboration between labs, and provides for business and scientific oversight boards to guide research toward...

Carnegie Mellon enhances Quantum Dot Corp. technology for long-term, live-animal imaging

...o fragile for most biological studies in vivo, the coating is the most critical step," explained Ballou, research scientist at the Molecular Biosensor and Imaging Center (MBIC) at Carnegie Mellon's Mellon College of Science. "The new coatings allowed us to observe quantum dots much longer than previously dem...

Purdue engineers develop quick, inexpensive method to prototype microchips

...f Chemical Engineers Journal, the team showed that coating the fibers with materials that attract different types of molecules allowed them to separate specific proteins from a mixed solution. By manipulating the fiber's properties, scientists can identify or separate various types of molecules, such as pro...

Researchers probe how microbes speed up acid production at mining sites

...chemistry: microbes react with the pyrite surface, coating it with chemicals that would be expected to hinder further reactions. Despite the formation of such coatings, however, microbe-mediated reactions occur tens of thousands of times faster than when no microbes are present. ''That's a puzzle,'' said Alf...

Scientists uncover amyloid-like proteins in bacteria

...genous chaplin proteins. The authors suggest that coating of the aerial hyphae by chaplin proteins may confer hydrophobicity to these structures, allowing them to grow into the air and possibly even preventing back-growth into the moist soil. "The hydrophobic nature of aerial structures could be an ideal p...

The Plasti-Bone

...aged bone has been removed. The calcium phosphate coating is very thin and allows the bone cells to attach themselves to the implant. Growth factors could be added to the calcium phosphate to encourage the bone growth at faster rates. "What is left of the real bone attaches itself to the polymer bone afte...

Gene may produce drought-resistant plants

...ontrols production of plants' outermost protective coating may allow Purdue University researchers to create crops with increased drought resistance. Scientists cloned the gene WAX2 after they discovered a fast-wilting mutant of Arabidopsis, a commonly used experimental plant. The gene is directly associated...

Scientists produce mouse eggs from embryonic stem cells, demonstrating totipotency even in vitro

...ese colonies. "These germ cells then accumulated a coating of cells similar to the follicles surrounding mammalian eggs," Schler said. "Starting on day 26, oocyte-like cells were released into the culture -- similar to ovulation -- and by day 43, embryo-like structures arose through parthenogenesis, or spon...

Technique brings immune-based therapies closer to reality

...ch, Oelke turned tiny magnetic beads into aAPCs by coating them with HLA-Ig and another protein that stimulates cell growth and exposing the beads to antigens from either melanoma or cytomegalovirus. "Using the aAPCs, we were able to make a tremendous amount of CTLs while maintaining their specificity," s...

Carnegie Mellon University chemists create versatile polymer brushes

... won't crack. These materials could work well as a coating for cars, where you want to combine a hard surface to avoid scratches with soft bulk properties to avoid cracking, according to Matyjaszewski. Other applications for polymer brushes include coatings that would provide a barrier to prevent corrosive ...

Bodys own antibodies may drive new strains of HIV

Polymers promote nerve regeneration

...h," Mallapragada said. "The grooves have a protein coating and we've also 'seeded' them with Schwann cells to help promote this growth." Schwann cells naturally form the myelin sheath around the PNS cells. When guided by this sheath, nerves will grow at a rate of three to four millimeters per day. The polyme...
