Gene clusters predict atherosclerosis severity, susceptibility
...Specifically, the researchers found that their new model
could predict with 93.5 percent accuracy the extent of atherosclerosis. It could also predict with 93.6 percent accuracy the location of atherosclerotic lesions. "This study is the foundation of future research and was absolutely critical study i...

New sequence involved in DNA replication timing may aid in cancer detection
...ng, Huberman and Yompakdee used fission yeast as a model
organism because of its small size, rapid cell cycle, and convenient genetics. "Human beings have 46 large chromosomes, while cells of the tiny fission yeast contain three much smaller chromosomes," noted Huberman. "Despite these differences, the pro...
