...able to replicate the intricate process using lab mice. They started by identifying the tiniest components of the HSV-1 strain. In its latent stage, HSV-1 produces a single molecular product, called latency-associated transcript RNA, or LAT RNA. Unlike most messenger RNA, LAT RNA doesn't produce proteins, so scientists have never been able to determine LAT RNA's exact function. But by inserting the LAT RNA into mice, Cullen found that it breaks down into even smaller strands called microRNA. Researchers then discovered that it was the microRNA that blocked production of the protein that activates...
...been a vegetarian for 37 years. I'm 61, 6 ft. 2 in., 185 lb. and healthy enough to compete in 100-mile mountain-bike races, ski, climb and dance all night with my wife. I've been living extremely well on rice and beans for protein, tofu, tempeh, fruits, greens, grains and 40 g of fiber daily. Meat and dairy products cause more obesity, heart disease and other ill-health consequences. Eat vegetarian for yourself and the planet! Join me on the starting line of the next mountain-bike race!

...gene involved in all these disorders codes for a critical brain protein known as the fragile X mental-retardation protein (FMRP). This protein normally acts as a brake on the production of other proteins associated with learning and memory. But when more than 200 CGG repeats are present, the gene for FMRP tends to shut down and production of the other proteins spins out of control. The brain develops too many connections, or synapses, many of them immature and flimsy. The resulting symptoms range from learning disorders to mental retardation and often include autism, epilepsy, anxiety disorders and attention-deficit...
...team at Chicago's Rush University Medical Center have begun trials with a drug called fenobam, originally designed as an antianxiety medication. MIT's Bear expects to begin trials with two other compounds later this year. The drugs target a receptor on brain cells that the fragile X protein normally helps regulate; the receptor, in turn, regulates proteins involved in learning and memory. "We're looking at a medication to reverse the retardation," says the optimistic Hagerman, "and I think we can achieve...
...future [June 16]? I've been a vegetarian for 37 years. I'm 61 and strong and healthy enough to compete in 100-mile (160-km) mountain-bike races, ski, climb and dance all night with my wife. I've been living extremely well on rice and beans for protein, tofu, tempeh, fruits, greens, grains and 40 g of fiber daily. Meat and dairy products cause obesity, heart disease and other ill-health consequences. Eat vegetarian for yourself and the planet, and join me on the starting line of the next mountain-bike race!
