Data suggest that it may pack an improved punch against gastric cancer
A new combination chemotherapy appears to battle advanced stomach cancer harder than other platinum-based therapies, while offering patients more convenience and potentially less discomfort, according to results announced at the 2005 Annual Meeting of the American Society of Clinical Oncology. Researchers studied the combination of a new drug, called S-1, and the platinum-based chemotherapy called cisplatin in patients with advanced gastric cancer.
Overall, 13 of the 20 patients (65 percent) evaluated so far in the phase II trial responded to the chemotherapy. That means tumors shrank in response to the drug. "We believe the therapy has the potential to not only fight cancer more effectively, but also is easier for cancer patients to deal with," says study co-author and medical oncologist Heinz-Josef Lenz, M.D., associate professor of medicine at the Keck School of Medicine of the University of Southern California and USC/Norris Comprehensive Cancer Center.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
