Last week the National Cancer Institute began testing CD4 in AIDS patients. ! The arrival of CD4, which had been previously tested in mice and monkeys, marks the beginning of a promising new era in drug development. Scientists have traditionally stumbled onto treatments by testing existing substances for their therapeutic effects, as was the case with AZT, the only AIDS drug approved for widespread use by the Food and Drug Administration. But recent advances in the field of molecular biology have given researchers a clearer understanding of the most minute workings of the cell. This has enabled them to engineer structures...
...Natural CD4 attracts gp120, a molecule on the surface of the AIDS virus. In the usual course of the disease, the virus uses the natural CD4 to attach itself to a T-4 cell, which it invades and ultimately destroys. Synthetic CD4, however, acts as a decoy by latching onto the AIDS virus and rendering it incapable of binding to T-4 cells -- a process that a National Cancer Institute spokesman likens to "putting putty all over a porcupine...
Like many outsiders after the war, he went first to Odessa and then to ) Midland, in the raw western part of Texas where the Permian oil pool was being divvied up by eager investors. So many Ivy Leaguers were moving onto the dusty fields that new streets were being laid out with names like Princeton Avenue. Bush brought his air of civic duty to places that did not have exactly the ethos of Greenwich town meetings. He was clearly interested in politics from the outset, and Playwright Larry L. King, then working for the local Congressman J.T. Rutherford, kept...
Soldiers slid the flag-draped coffins of Zia, Raphel and 28 others onto planes bound for Islamabad and other Pakistani cities where relatives of the victims were waiting. The government originally put the death toll...
When the gleaming white space orbiter Discovery moved onto the launch pad at the Kennedy Space Center in Florida early last month, it became both a soaring symbol and a thorny trial for NASA. On one hand, the 122-ft.-tall orbiter represented the agency's successful recovery from the tragic explosion 2 1/2 years ago of Challenger, the last manned U.S. space mission. Discovery was also a test: Could NASA, operating this time around with extraordinary caution and under intense scrutiny, pull off an A-O.K., on-time launch? That question has caused growing frustration in the space...
