...makes nearby capillaries leaky. This allows small amounts of plasma to pour out, slowing down invading bacteria, and prepares the way for other faraway immune defenders to easily enter the fray. Meanwhile, another group of sentinels, called macrophages, begin an immediate counterattack and release more chemicals, called cytokines, which signal for reinforcements. Soon, wave after wave of immune cells flood the site, destroying pathogens and damaged tissue alike - there's no carrying the wounded off the battlefield in this war. (No wonder the ancient Romans likened inflammation to being on fire...
...test his hunch, Ridker needed a simple blood test that could serve as a marker for chronic inflammation. He settled on Creactive protein (CRP), a molecule produced by the liver in response to an inflammatory signal. During an acute illness, like a severe bacterial infection, levels of CRP quickly shoot from less than 10 mg/L to 1,000 mg/L or more. But Ridker was more interested in the low levels of CRP - less than 10 mg/L - that he found in otherwise healthy people and that indicated only a slightly elevated inflammation level. Indeed, the difference between normal and elevated...

Yet rising interest rates attract foreign investment and often buoy the dollar, which firmed noticeably after Greenspan's rate signal in late January. The buck may hold firm if, as seems logical, Europe cuts interest rates to combat slow growth. A steady dollar would remove the currency edge of foreign securities, which in dollar terms rose nearly twice as much as they did in local currencies last year. You should favor...
...says a presidential adviser. "People aren't going to care about Halliburton...They're going to care about who can protect them." For his part, Cheney is amused by the Democratic attacks. "That's politics," he says to friends, grinning his trademark half grin and shrugging his shoulders to signal there's nothing to worry about. --By Matthew Cooper/Washington
