Snow Fleas Key To More Organ Transplants
Kingston ON (UPI) Oct 24, 2005 A new antifreeze protein discovered in tiny snow fleas by Canadian researchers may allow organs to be stored longer before being transplanted. Drs. Laurie Graham and Peter Davies - at Queen's University, in Kingston, Ontario - found that the potent protein produced by the fleas to protect themselves against freezing is capable of inhibiting ice growth by about 6 degrees Celsius. This would allow organs to be stored at lower temperatures, expanding the time allowed between removal and transplant, the researchers say in the journal Science. "Transplant organs must now be kept at the freezing point or slightly warmer," says Graham. "If we can drop the temperature at which the organ is safely stored, there will be a longer preservation period."

Researchers Make Long DNA Wires For Future Medical And Electronic Devices
Columbus OH (SPX) Dec 18, 2005Ohio State University researchers have invented a process for uncoiling long strands of DNA and forming them into precise patterns. Ultimately, these DNA strands could act as wires in biologically based electronics and medical devices, said L. James Lee, professor of chemical and biomolecular engineering at Ohio State University. |
