Cincinnati surgeons report new treatment for often-fatal injury

...ring a common and deadly form of aortic injury--an advance that could help reduce the number of deaths caused by auto accidents and major falls. The potentially life-saving technique is reported by Joseph Giglia, MD, interim director of UC's division of vascular surgery, and his team in the March edition of...

Brittle prions are more infectious

...SF reported their findings on June 28, 2006, in an advance online publication in Nature. The scientists studied yeast prions, which are similar to mammalian prions in that they act as infectious proteins. In recent years, mammalian prions have gained increasing notoriety for their roles in such fatal brain-...

Researchers map out networks that determine cell fate

... systems." This finding "represents a significant advance in understanding the molecular mechanisms that regulate [stem cell] development," according to a commentary in the journal by Dale Muzzy of Harvard University and Alexander van Oudenaarden of the Massachusetts Institute of Technology. "Irreversible ...

Flick of a protein switches immune response

...ing light on the immune system, the Cell paper may advance biology and medicine toward a much larger goal: how to turn single genes on or off. "This [result] has far-reaching implications for understanding the principles of signal transduction and transcriptional networks of living cells," Chen said. The...

Chimpanzees can transmit cultural behavior to multiple 'generations'

...replacement therapy; address vision disorders; and advance knowledge about the evolutionary links between biology and behavior. ...

Microscopic scaffolding offers a 'simple' solution to treating skin injuries

...ectrospinning***. However, the team has made a key advance by developing a new method of making, from the same biodegradable polymers, aligned-fibre 'mats' of potential use in promoting nerve or tendon growth. This method is currently being patented. The next step in the research is to develop the skin r...

DNA: Bacteria's survival ration

...e in such pathogens, as Finkel did in E. coli, the advance might lay the groundwork for a new class of genetic antibiotics. The study did not prove that all DNA decay is microbial. But Finkel discounted the significance of inorganic processes, citing the chemical stability of genetic material. If a thick la...

Cycles of cell death, proliferation key to liver cancer

... research, appearing online the week of June 19 in advance of publication in the journal Proceedings of the National Academy of Sciences, underscores the importance of JNK1-mediated cell death and compensatory proliferation. The findings by Michael Karin, Ph.D., professor pharmacology in UCSD¡¦s Laboratory ...

Radiation-killed bacteria vaccine induces broad immune response in mice

... capable of eliciting a T-cell response. "This advance is potentially of great importance in meeting the challenge of creating vaccines that are safe, effective and simple to manufacture and transport," says NIH Director Elias A. Zerhouni, M.D. Ideally, vaccines should stimulate a strong response not...

DOE JGI sequences, releases genome of symbiotic tree fungus

... "This unique research opportunity enables us to advance the understanding of how functional genomics of this symbiosis enhances biomass production and carbon management, particularly through the interaction with the poplar tree, also sequenced by DOE JGI," Rubin said. "We can now harness the interaction ...

Parkinson's disease mechanism discovered

...ectronic publication of selected Science papers in advance of print. Lindquist is at the Whitehead Institute for Biomedical Research and Bonini is at the University of Pennsylvania. Antony Cooper of the University of Missouri-Kansas City and Aaron Gitler, who is in Lindquist's laboratory, were co-lead author...

Microscopic passengers to hitch ride on space shuttle

...tle resources, but it has the potential to greatly advance infectious disease research in space and on the ground," said Steven Hing, the experiment's project manager at NASA Ames, in California's Silicon Valley. With these 'bugs' already present or with the potential to be present in human-occupied spacec...

MIT sheds light on how tumor cells form

...nd spreading. The work was reported June 8 in the advance online issue of The EMBO Journal, a publication of the European Molecular Biology Organization (EMBO). Tumor cells that grow aggressively often have an irregular number of chromosomes, the structures in cells that carry genetic information. The norm...

Protein clue to tailor-made antibiotics

...n the Department of Biology has made a significant advance in understanding how bacteria use proteins to conduct a type of biological warfare. Bacteria like E. coli frequently try to kill each other when resources are scarce using protein antibiotics called colicins, which are potent toxins. The researc...

Neurons grown from embryonic stem cells restore function in paralyzed rats

...Annals of Neurology.* "This work is a remarkable advance that can help us understand how stem cells might be used to treat injuries and disease and begin to fulfill their great promise. The successful demonstration of functional restoration is proof of the principle and an important step forward. We must r...
