This would also help the vaccine get past regulators at agencies like the FDA. Medications are approved based on an "indication," a medical problem or risk suffered by an individual. If a TBV were not part of a combination vaccine, this "indication" would be hard to define. Of course, the traditional vaccine that would make the TBV acceptable doesn't exist yet either, but progress is being made on that front. Right now, for example, PATH MVI is testing a vaccine called RTSS, which reduced risk of infection for one strain of the disease at least 50% in late-stage...
...substance roster in 1991, but no testing was mandated. Fans and officials largely turned a blind eye, even as players' bodies swelled along with their achievements. In 1999, even after McGwire had copped to taking androstenedione - or "andro," an over-the-counter precursor to testosterone later banned by the FDA - Senator Edward Kennedy called the slugger and his rival Sosa the "home-run kings for working families in America." A year later, the suggestion in the New York Times that up to 40% of major league players had taken steroids was largely met with crickets...
...than $2.6 billion in sales in the U.S. in 2008. But acetaminophen can also put stress on the liver. From 1990 to 1998, there were an estimated 56,000 emergency-room visits, 26,000 hospitalizations and 458 deaths related to acetaminophen overdoses, according to the Food and Drug Administration (FDA). These figures include everything from attempted suicides to people who gulped down entire bottles trying to get well, and it is difficult to tease out just how many people got sick because of tiny overdoses. To address at least some of these cases, the FDA convened a panel of experts...
...good news: scientists are learning to manipulate epigenetic marks in the lab, which means they are developing drugs that treat illness simply by silencing bad genes and jump-starting good ones. In 2004 the Food and Drug Administration (FDA) approved an epigenetic drug for the first time. Azacitidine is used to treat patients with myelodysplastic syndromes (usually abbreviated, a bit oddly, to MDS), a group of rare and deadly blood malignancies. The drug uses epigenetic marks to dial down genes in blood precursor cells that have become overexpressed. According to Celgene Corp. - the Summit, N.J., company that makes azacitidine - people...
Since 2004, the FDA has approved three other epigenetic drugs that are thought to work at least in part by stimulating tumor-suppressor genes that disease has silenced. The great hope for ongoing epigenetic research is that with the flick of a biochemical switch, we could tell genes that play a role in many diseases - including cancer, schizophrenia, autism, Alzheimer's, diabetes and many others - to lie dormant. We could, at long last, have a trump card to play against Darwin...
