...scientists' probe, known as a contrast agent, targets a specific enzyme in the tumor known as cathepsin b. The enzyme turns on the compound "like a switch," said Research Fellow in Radiology Ching H. Tung, who co-authored the experiment with first author Weissleder, senior author and Assistant Professor of Radiology Alexei A. Bogdanov and Clinical Fellow in Radiology Umar Mahmood...
...regular tumor detection right now there is a lot of misdiagnosis because you can't diagnose the early stage of the tumor growth," said Tung. "We've developed contrast agents so hopefully we can detect the signal from the tumor, and detect the tumor, earlier...
...slightly weird consequence for this show. The older works--the ones from the teens, '20s and '30s--look fresher than the younger ones. We are used to seeing endless reproductions of de Kooning, Pollock, Rothko--but not of Elie Nadelman, Arthur Dove or Joseph Stella. Because of this contrast, the top two floors of the show--it starts at the top and, taking advantage of gravity, goes downward--seem more interesting than the third. That's not the art's fault, but it goes a long way toward fixing the imbalance in Americans' views of their own past...
...success of these two giant tragedies is notable, for they stand in marked contrast to most of the pygmy-size works around them. New plays these days tend to be small, tidy things, dramas that tend their own little garden and don't venture very far into the wild outdoors. Hare's The Blue Room, which brought Nicole Kidman to Broadway earlier this season, reduced Schnitzler's La Ronde to a trivial actors' exercise for two. Hare then went one better (or one lesser) by appearing onstage alone, recounting his trip to the Middle East and calling it a play...
...puzzle, the scientists infected the unformed wing region of day-old chicken embryos with a virus carrying a T-box gene known as Tbx-4. A day later, they transferred the tissue to other embryos still in their shells. The transplanted cells quickly grew into recognizable legs. By contrast, when the scientists transferred wing tissue without first infecting it with Tbx-4 genes, the tissue always grew into wings. That shows that Tbx-4 contains a full genetic blueprint for a leg, says Belmonte...
