The new work, described in Thursday’s issue of the journal Nature , shows that even a single cell plucked from an early human embryo can be coaxed to divide repeatedly in a laboratory dish and grow into a colony of stem cells, coveted for their potential to mend failing organs. It is already common for fertility doctors to remove a single cell from a days-old embryo before transferring that embryo into a woman’s womb – part of a test to screen out embryos bearing genetic defects. Although the safety of the cell-removal process is still under study, there is no evidence that the procedure puts embryos at significant risk or that babies born from such "biopsied" embryos are abnormal in any way.

"To his credit, it's recognition that the science is reliable," USADA general counsel Travis Tygart said. "Instead of wasting a bunch of resources attempting to create smoke where there's not any, he's acknowledging the accuracy of the positive test. And in exchange for his agreement to cooperate, we've recognized the nature of his first offense. "The first offense occurred while Gatlin was in college. He stopped taking his medicine a few days before competition, but it did not clear his system. He received a two-year ban, which was reduced by a year because of "exceptional circumstances. "Gatlin has said he doesn't know how steroids got into his system this time… And in exchange for his agreement to cooperate, we've recognized the nature of his first offense.

Another of his attorneys, John Collins, said Gatlin would spell out his case at the arbitration hearing. He would not discuss strategy.
Molecular Process Underlying Leukemia Identified By Study

The study also identified an enzyme’s important role in this process. The results were published online Aug. 20 and will appear in a future print issue of the journal Nature Cell Biology. The research was led by Dr. Yi Zhang, professor of biochemistry and biophysics in the UNC School of Medicine and a Howard Hughes Medical Institute Investigator. Zhang is also a member of the UNC Lineberger Comprehensive Cancer Center. The work was supported by grants from the National Institutes of Health… 20 and will appear in a future print issue of the journal Nature Cell Biology.

The study examined chromosomal translocation, in which a fragment of a chromosome breaks off and joins another. Chromosomes are the cellular structures that carry DNA.
How HIV “Exhausts” Killer T Cells

However, he cautioned that these kinds of drugs could cause serious side effects, including autoimmune reactions that trigger the immune system to attack the body. Walker added that the researchers’ findings will also likely have application in understanding other chronic viral diseases. The findings by Walker and his colleagues were published in an advance online publication on August 20, 2006, by the journal Nature. Walker is also at the Partners AIDS Research Center and Harvard Medical School. Other co-authors were from the University of KwaZulu Natal in South Africa, Oxford University, Dana-Farber Cancer Institute of Harvard Medical School, Emory University School of Medicine, and The Wistar Institute.
