Northwestern Memorial Hospital studying arthritis drugs potential in fighting cancer
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."
Based on successful clinical trials, Celebrex has been FDA-approved to treat those with a genetic syndrome, called familial adenomatous polyposis (FAP), a disorder that greatly increases the risk of colon cancer. Researchers expect that Celebrex may have similar positive effects for cancer treatment and prevention of other cancers.
Several clinical trials are under way to look at COX-2 inhibitors and their ability to prevent and treat a variety of cancers. "As far as I know, this is the only current study of its kind for head and neck cancer," says Dr. Argiris. "Im expecting that COX-2 inhibitors, such as Celebrex, may slow tumor growth or shrink existing tumors in people with head and neck and lung cancers. Moreover, COX-2 inhibitors may act early in the cancer process and prevent formation of new tumors," says Dr. Argiris. "Celebrex is considered to be safer on the stomach than aspirin, so the reduced gastrointestinal side effects make this an especially exciting therapy," says Dr. Argiris.

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
