Then there are the 100-page analyses, dissecting each feasible theme in Edith Wharton novels, and the usual incomprehensible, highly obscure science papers. For instance, the thesis entitled Single Voxel Proton Nuclear Magnetic Resonance Spectral Editingmight have won a Hoopes Prize, but its title doesn't muster up visions of trashy reading on the beach...
...turned to drugs like Tagamet and Pepcid to block a biochemical signal that sets off acid production. Neither of these remedies, now available over the counter, can turn off the stomach's acid-making machinery at the source, however. That's where a new group of prescription medications, called proton pump inhibitors, comes in. "You don't just get better on these pills," Dannenberg exults, "you actually return to normal." And because the drugs are activated only in the acid environment of the stomach, they are very safe...
