A research study under way at Northwestern Memorial Hospital is trying to find out if the popular anti-inflammatory drug Celebrex might do more than ease arthritis pain. Researchers at Northwestern Memorial are enrolling patients with early stage head and neck cancers or non-small cell lung cancers in a research study to see if Celebrex reduces the return of old tumors or the chance of getting a new cancer when taken after surgery or radiation treatments.
The double-blind, randomized study will enroll about 120 patients at Northwestern Memorial, the primary teaching hospital of Northwestern Universitys Feinberg School of Medicine. Celebrex belongs to a class of drugs called COX-2 inhibitors that block the production of an enzyme called cyclooxygenese–2 or simply COX-2. COX-2 triggers pain and inflammation in arthritis sufferers and may also fuel the growth of cancer.
"COX-2 inhibitors have emerged in recent years as a promising anticancer therapy. Many cancers have high levels of COX-2," explains Athanassios Argiris, M.D., an oncologist at Northwestern Memorial Hospital. Dr. Argiris, who coordinates the clinical research in lung as well as head and neck cancer at the Robert H. Lurie Comprehensive Cancer Center, is the principal investigator of the research study, which is also expected to open in other major institutions in the U.S. in the coming months. COX-2 may promote the growth of new blood vessels that nourish the cancer tumors. "Taking Celebrex may starve the tumor of nutrients in a process called anti-angiogenesis," he says. "It also appears to promote self-destruction of cancer cells."

Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.
Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....
Empa researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range – and they are unrivalled in terms of weight.
Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic...

With an X-ray experiment at the European Synchrotron ESRF in Grenoble (France), Empa researchers were able to demonstrate how well their real-time acoustic monitoring of laser weld seams works. With almost 90 percent reliability, they detected the formation of unwanted pores that impair the quality of weld seams. Thanks to a special evaluation method based on artificial intelligence (AI), the detection process is completed in just 70 milliseconds.
Laser welding is a process suitable for joining metals and thermoplastics. It has become particularly well established in highly automated production, for...
