...search and speculation went on, researchers in U.S. labs added their own clues: the blood of AIDS victims has an imbalance among the cells that help govern the production of antibodies. A normal immune system has twice as many helper Tcells, which stimulate the making of antibodies, as it does suppressor Tcells, which keep antibody production under control. In an AIDS victim, the ratio may be reversed. Often there are fewer cells of both types...
...that AIDS is caused by a specific agent, most probably a virus. "The infectious-agent hypothesis is much stronger than it was months ago," says Curran, reflecting the prevailing opinion at CDC. NIH Researcher Fauci, who staunchly believes that the culprit is a virus, has been collecting helper T-cells from AIDS victims to look for bits of viruses within their genetic codes. So far, however, this and other complex methods of detecting viruses have yielded nothing conclusive. Suspicion focuses on two viruses: one is a member of the herpes family called CMV; the other, called human T-cell leukemia...
...writing this letter to warn female undergraduates of the harassment and exploitation which is part of some summer employments. Accepting a position as a deck hand and domestic helper should not subject a female employee to degrading glances, stray hands, or more direct approaches in manipulated, one-on-one encounters. Don't be lured into a false sense of security or immunity by a man's credentials. Happily married, distinguished Harvard alumni, in the luxury of their secluded summer homes, can be found guilty of such offenses. In a previous summer position, such a man proved this...
...while the team's 11-8 mark didn't quite match last year's 15-6 record, this year's opposition proved to be a far helper obstacle than any before it. "We'd never played the likes of UNH before." Dooley says. "It might not show in the record but we gained some invaluable experience that'll certainly help us in the future...
...AIDS patients appears to be unique, affecting white blood cells called T lymphocytes (T for thymus, which plays a role in their development). Certain of these cells help defend the body against viruses, foreign tissue (like organ transplants) and the growth of cancer cells. There are several types, including helper T cells, which promote the production of antibodies against foreign invaders, and suppressor T cells, which reduce antibody output. Healthy individuals have twice as many helpers as suppressors. In AIDS victims, the ratio is reversed; helper cells are depleted. No one knows what happens to these cells, but New York...
