...next step, researchers said, is to create a ribosome that will be completely synthetic, without the use of bacterial RNA and other protein additives...
...negative correlation between caffeine intake and the risk of developing non-melanoma skin cancer. According to the study, caffeine appears to reduce the risk of some skin cancers by interrupting the ATR pathway, causing apoptosis or cell suicide of these damaged and potentially cancerous cells. ATR is a protein kinase that is responsible for facilitating the replication of DNA, especially in damaged and dividing cells. While ATR plays a minimal role in normal cells, recently damaged and precancerous cells need the function of ATR, Nghiem explained. The researchers determined that low levels of caffeine have no effect on normal cells...
...unforeseen was exactly what turned up when Pat went in for a physical on Nov. 30, 2007, his first in five years. The doctor found high levels of blood and protein in his urine, results that were confirmed in another round of tests in December. Soon after that, Pat discovered that his urine had turned brown and foamy. In the middle of all this, he was laid off from his job, and finding a new one while doing temp work was his most pressing concern. Finally, last July my brother's doctor insisted that he see a specialist, who quickly...
...were fed formula that contained little or no nutritional value. Last year at least six infants died and some 300,000 were sickened after consuming milk made from powder contaminated with melamine, a chemical used in making plastics. Melamine added to a diluted or inferior milk can make its protein content appear artificially high. When consumed in large quantities, it can lead to formation of dangerous crystals in the kidneys that can result in organ failure...
...roulette for the food-allergic. Which is why some researchers are trying to find a better way to treat allergies than simply advising their patients to avoid certain foods. In a new strategy called oral immunotherapy, doctors try to retrain the immune system by hitting it with the offending protein enough times, in increasing doses, that the body's defenses eventually relent and accept the protein as friend rather than foe. "It's the first generation of treatment that would make people less or even no longer allergic," says Dr. Wesley Burks, chief of pediatric allergy and immunology at Duke...
