...structure of the AIDS virus. "We analyze the virus' DNA sequence to get a blueprint on what the virus can do," explains Haseltine, who is an associate professor of pathology at the Med School. His lab has found a number of unusual genes on the AIDS virus including the tat-gene which makes it possible for the AIDS virus to replicate many times faster than the average virus, and the art-gene which regulates the virus' speed of reproduction...
Haseltine's discovery of the tat-gene may prove to be extremely important in the drug development process. Without the tat-gene the virus can't grow, so if researchers can find a chemical which interferes with the workings of that gene, or any other essential virus process, they are well on their way toward finding a drug treatment program...
Conference Co-Chairman Robert C. Gallo of the National Cancer Institute praised a recently announced discovery by a Harvard professor. Associate Professor of Pathology William Haseltine last week announced he has found that the AIDS virus does not reproduce if scientists remove one of its genes, called the tat gene...
Later that afternoon, while he is waiting for his room at the Flamingo Hilton, Donald Persson deposits three quarters into a slot machine, one of the largest bets of his life, and pulls the lever. The wheels fall into place, and the coins start firing rat-a-tat into the metal change bucket. Persson takes a seat, drops three more quarters and contemplates just what he has been missing for the past 57 years. By the time his wife Myrna disconnects him from the machine and persuades him to visit a cashier, he is up $153. He hardly needs...
...field. Some 40,000 Grenadians waiting for their first words from the President of the United States swayed to the lyrics of the country's most popular ballad. The song, which recounts the landing of U.S. troops on the tiny Caribbean island, mimics the drone of helicopters, the "rat-tat-tat" of machine guns and the boom of big guns as it pays exuberant tribute to the island's liberator, "Uncle Reagan...
