...main propellant for the craze has been the presumption that calcium can ! help prevent osteoporosis, the degenerative bone disease that afflicts an estimated one-quarter of elderly men and half of elderly women in the U.S. Three years ago scientists at a National Institutes of Health conference on osteoporosis advised Americans to increase their daily intake of calcium to 1,000 mg (compared with the Government RDA of 800 mg); the recommended level for postmenopausal women was an even higher 1,500 mg. Calcium fever soon swept the country...
Calcium supplements, unfortunately, cannot prevent osteoporosis after menopause. At the Bethesda meeting, researchers reported on eight studies that found extra calcium had little or no effect in slowing bone loss, even / when the dosage was as high as 3,000 mg per day. The most effective defense against osteoporosis in these women, all agreed, is estrogen replacement. Such therapy has been linked in the past to an increase in endometrial cancer, but doctors now believe the risk can be minimized by tandem use of progesterone- like hormones...
...stems in part from a decision to focus on extracurriculars at the expense of academics: for me, this was The Crimson. In part, it can reflect the selection of a large concentration.

...strand of RNA, when absorbed by genital cells in mice, can destroy the messenger RNA responsible for expressing the HSV-2 virus, which is carried by over 20 percent of American adults.Lieberman says she hopes that this process can become the basis for a convenient, inexpensive drug that can prevent the transmission of genital herpes.“A problem with most microbicides is that most people have to use them before they have sex, and application is an issue,” Lieberman says. Since RNAi can suppress gene expression for long periods of time, Lieberman says...
