...think that would be a huge deal. The scientists, from three private labs in La Jolla, Calif., and Detroit made the clones by a technique called somatic cell nuclear transfer: They took the nuclei from skin cells of adult men, inserted the genetic material into enucleated eggs from female donors, and got the eggs to begin dividing, forming embryos containing stem cells. In principle, replacement tissues grown from those cells would be genetically identical to the men they came from. So they could, in principle, be used to fix failing organs, without any fear of rejection...
...problem, as with every recent stem-cell advance so far, is that the principle and the practice are still awfully far apart. No one doubts that the scientists created cloned embryos - largely because they documented their techniques so carefully and performed confirming tests, but also because they aren't the first to have made clones (British scientists did it two years...
Increased levels of cholesterol, a lipid found in cell membranes, have been shown to promote hardening of the arteries, which can lead to cardiovascular disease...
...beginning of this decade, proved less effective in patients than in mice, giving skeptics yet another reason to doubt the approach. But that agent, dismissed by U.S. researchers, eventually won approval in 2005 for treating lung cancer in China, where it is extending the lives of non-small-cell lung cancer patients...
...hypertension and buildup of gunk in blood vessels that increases heart-attack risk. But there are short-term effects too. "People don't understand this, even most physicians," says O'Keefe. Tissue becomes inflamed, just as it does when infected. Blood vessels constrict. Free radicals, unstable molecules that cause cell damage and are thought to contribute to chronic disease and aging, are generated. The body's stress response has a bigger effect on blood pressure, raising it higher than normal. People may notice they feel crummy a few hours after eating junk food. And the sudden surge and drop...
