Single-mindedly, the AIDS virus ignores many of the blood cells in its path, evades the rapidly advancing defenders and homes in on the master coordinator of the immune system, a helper T cell. On the surface of that cell, it finds a receptor into which one of its envelope proteins fits perfectly, like a key into a lock. Docking with the cell, the virus penetrates the cell membrane and is stripped of its protective shell in the process. Within half an hour, the strand of RNA and an enzyme the virus carries with it are floating in the cytoplasm...
...molecule then penetrates the cell nucleus, inserts itself into a chromosome and takes over part of the cellular machinery, directing it to produce more AIDS viruses. Eventually, overcome by its alien product, the cell swells and dies, releasing a flood of new viruses to attack other cells, including more helper T cells and macrophages. The immune system, deprived of a crucial number of those vital T cells, is unable to direct the fight against infection. A host of opportunistic diseases, normally warded off by a healthy immune system, attacks the body. Gradually weakened by the onslaught, the AIDS victim dies...
...Late night procrastinators still cannot purchase the new soda in Harvard Square. Local vendors--like Sage's, Store 24 and Christie's Market--do not yet carry the product and give no date when they might stock the lightning-clad cans. The closest vendor which offers the all-nighter helper is Bloomingdale's at the Chestnut Hill Mall...
...effect was indeed extraordinary. By mid-September there had been 16 deaths among the 137 patients receiving the placebo and only one among the 145 taking AZT. Those being given the drug developed fewer AIDS-associated infections, gained weight and showed growing numbers of helper T cells (the immune-system cells attacked by the AIDS virus) in their bloodstream. The independent review board of AIDS experts, set up by a division of the National Institutes of Health in February, promptly recommended that the study be halted and the drug given to the placebo patients...
...very affectionate. I'm very lucky." There are children in their future. And a Durang; Chris and Sigourney will keep acting, writing and capering. Though Weaver says she would "play anything -- a broom, a mop" in a Woody Allen film, she wants to be more than a housewife's helper in other roles. "Usually women in films have had to carry the burden of sympathy, only coming to life when a man enters. Doesn't everyone know that women are incredibly strong?" Right you are, Sigourney. Anyway, no one would argue with a woman who patented perfection, then showed...
