Chemical derived from vitamin-E shows early promise as cancer drug
...y to divide, alpha-TEA caused the cancer cells to shrink and die through a process called apoptosis compared to untreated breast cancer cells. "One reason that alpha-TEA is such a potent anti-cancer agent is that it impacts on numerous anti-growth and pro-death cellular processes in cancer cells but...Goals unlikely to protect Gulf of Mexico shrimp industry
...30 percent nitrogen load reduction will not likely shrink the dead zone to the desired 5,000 square kilometers.

...Such early (neo-adjuvant) treatment could not only shrink the primary tumour but might also prevent the outgrowth of micrometastases, thereby saving lives, as metastases that occur in other parts of the body are notoriously difficult to treat successfully and are the main cause of death in breast cancer.
