A once-a-day pill has been proven to lower the risk of getting HIV among needle-using drug addicts, just as it does among heterosexual couples and men who have sex with men.
Among 2,400 injecting drug users in Bangkok, those assigned to take a daily dose of an antiviral drug Viread, or tenofovir generically, had half the risk of getting HIV over a four-year period as those who took a placebo pill. Among those who took tenofovir faithfully, there were 74 percent fewer infections.
In order to make tough cuts of beef more tender, the industry uses a mechanical tenderizing process that involves piercing the meat with needles.
This is effective in breaking up the tough muscle fibers, but there's a downside, too: a higher risk of surface bacteria making their way into the cut of meat, which can set the stage for food poisoning. That's a particular concern when it comes to the center of meat cuts, which don't get heated to the same temperatures as the exterior.
