What roused these '60s-style protesters was a quintessentially '90s issue: whether a genetically engineered hormone that went on sale last week after nearly 10 years of legal wrangling threatens the safety of American milk. The hormone, a natural protein found in cows, is being artificially manufactured in vats of genetically altered bacteria. When cows are regularly given extra doses of the hormone, their milk production can rise as much as 15%. Scientists call the chemical bovine somatotropin (BST) or, more simply, bovine growth hormone (BGH), and it is marketed under the trade name Posilac...
Harvard Dining Services' recent attempt to print nutritional information about all items it serves has drawn mixed reviews. Some find the tabulation of fat, carbohydrates, protein and calories a useful yardstick, while others decry these "bites" as nasty barbs that are incompatible with eating enjoyment. We at Dartboard feel that the new program would meet with universal acclamation if it were to imitate another popular campus rating system: namely, the CUE guide...
...long before they can be fixed. In some cases the knowledge may lead to treatments that delay the onset of the disease or soften its effects. Someone with a genetic predisposition to heart disease, for example, could follow a low-fat diet. And if scientists determine that a vital protein is missing because the gene that was supposed to make it is defective, they might be able to give the patient an artificial version of the protein. But in other instances, almost nothing can be done to stop the ravages brought on by genetic mutations...
...study appearing in the December 1 issue of the Proceedings of the National Academy of Sciences showed that a mixture of two drugs--pentoxifylline and Ro24-7429--was 100 times more effective than either drug alone at blocking the function of "Tat," a viral protein essential to the spread of HIV in the body...

Cazanjan, assistant professor ofmedicine and director of the AIDS program at theBrigham and Women's Hospital said in a phoneinterview yesterday that while there has beenexperimental evidence to support the effectivenessof other drugs to block the Tat protein, "so farthe clinical experience with tat inhibitors hasnot been fruitful...
