Brain tumors have long presented a major challenge to drug delivery because of the especially leakproof blood-vessel walls in the brain, which make it difficult to administer conventional chemotherapy there. Drug-bearing wafers may be one answer. After the brain surgeon removes as much of the tumor as possible, small drug wafers are inserted at the tumor sites. Over time the wafers slowly release a chemical that prevents the recurrence of new tumors. The technique seems to work. A 1997 clinical trial showed that after two years, 31% of glioblastoma patients with implanted wafers were still alive, compared with...
Noah's Ark has set sail again, crossing stormy scientific waters and buffeted by winds of controversy. Unlike the Old Testament vessel, however, today's metaphorical ark is not carrying threatened animals two by two to safety. Rather, if it lives up to its billing, it could produce potentially unlimited numbers of endangered creatures...
...already suspected: when it comes to heart attacks, angioplasties save more lives than clot-busting drugs. Both treatments aim to clear arterial blockages that deprive the heart of oxygen. But the odds of dying in a hospital after an emergency angioplasty--a balloon-tipped catheter is threaded through the vessel--are 40% lower than after a round of clot busters. Caveat: the finding applies only to centers that perform angioplasties frequently--at least 50 times a year...
...honest meal ticket, the U.S. Army, shipped home the last of its intervention forces. "I may have to join my friends and be a welder," he said--not just any welder but a narco welder, who refits ships to hide drugs. Marnet walked to a cargo vessel, where two large generators powered the torches he said his pals were using to solder double hulls and other secret compartments. On a matchbox, he drew the designs they were following. He then pointed to their nearby bosses, who were opening Samsonite suitcases stuffed with cash in full view of police...
...Haiti's imaginative narco welders have forced an inspection revolution. Customs teams often spend days dismantling keels, engine rooms and even onboard septic tanks and voodoo shrines that have yielded as much as 1,100 lbs. of coke at a time. "We've never seen the Colombians use a vessel's structure this way," says Miami customs supervisor Tom Stefanello over the racket of his agents' riveters...
