An Entirely New Direction For RNAi Delivery - The Future Of Personalized Cancer Treatment
In technology that promises to one day allow drug delivery to be tailored to an individual patient and a particular cancer tumor, researchers at the University of California, San Diego School of Medicine, have developed an efficient system for delivering siRNA into primary cells. The work was published on May 17 in the advance on-line edition of Nature Biotechnology.

Other "-Caines" Often Replace Novocaine In The Dentist's Office - Chemical & Engineering News

Novocaine? Not necessarily. The widespread belief that dentists rely on Novocaine to make those office visits almost painless needs some updating, according to an article scheduled for the June 29 issue of Chemical & Engineering News, ACS" weekly newsmagazine. In fact, patients are more likely to get any of several other anesthetics than the century-old standby Novocaine, which once reigned as the archetypal dental anesthetic. C&EN senior editor Elizabeth Wilson notes that Novocaine, also known as procaine, has become a catchall term for a variety of dental anesthetics widely used today. These substances include less-familiar names like benzocaine, lidocaine, articaine, and mepivacaine. Like Novocaine, all are non-addictive relatives of the original, naturally occurring local anesthetic cocaine, which is found in coca leaves. None of the newer local anesthetics are perfect, leading scientists to seek better medications that are faster-acting, more effective, and safer. Wilson"s article describes not only this ongoing quest, but also research to determine exactly how dental anesthetics work in the body. "Dental anesthetics" American Chemical Society
