Chemists at the University of California-Santa Cruz say they've developed novel compounds that show promise for photodynamic cancer therapy. The compounds, called dye-sensitized ruthenium nitrosyls, are absorbed by cancer cells and respond to specific wavelengths of light by releasing nitric oxide, which triggers the cancer cells' death, the researchers said. For cancer treatment, you want localized delivery of a very high concentration of nitric oxide, said Professor Pradip Mascharak. We've...

Chemists at the University of California, Santa Cruz, have developed novel compounds that show promise for photodynamic cancer therapy, which uses light-activated drugs to kill tumor cells.The new compounds, called dye-sensitized ruthenium nitrosyls, are absorbed by cancer cells and respond to specific wavelengths of light by releasing nitric oxide, which triggers cell death."For cancer treatment, you want localized delivery of a very high concentration of nitric oxide. We've designed these...

Panel also addresses limitations of current randomized trials MENLO PARK, Calif., June 2 /PRNewswire/ -- Apieron, Inc. highlighted recent clinical panel presentations underscoring the positive impact of measuring exhaled nitric oxide (eNO) for treating asthma in adults and children. The company also cited recognition that design and methodology issues led to mixed results in some randomized trials of eNO-guided therapy. Apieron develops and markets non-invasive monitors that measure exhaled...

Robert F. Furchgott, whose research earned him a share of a Nobel Prize and helped lead to the anti-impotency drug Viagra, has died, a daughter said. Susan Furchgott said her father died Tuesday in Seattle, The Ledger in Lakeland, Fla., reported Saturday. He was 92. The elder Furchgott was a pharmacologist who, with Louis J. Ignarro and Ferid Murad, shared the 1998 Nobel for physiology or medicine after proving nitric oxide affected blood pressure and blood flow. Furchgott's discovery that...

A new drug-delivery system with an anti-microbial agent may treat potentially deadly drug-resistant staph infections in mice, U.S. researchers said. For the study, researchers at Albert Einstein College of Medicine of Yeshiva University in New York used mice infected with methicillin-resistant Staphylococcus aureus. The drug delivery system used biocompatible nanoparticles -- each smaller than a grain of pollen -- to produce controlled and sustained amounts of nitrous oxide gas. Nitrous oxide...

University of Michigan scientists say they are developing a new method of detecting nitric oxide in exhaled breath. Since an elevated concentration of nitric oxide in one's breath is a sign of many diseases -- including lung cancer and tuberculosis -- the researchers said their new technology could prove useful in diagnosing illness and monitoring the effects of treatment. Assistant Professor Anne McNeil and graduate student Jing Chen work with molecular gels consisting of small molecules....

A Boston University School of Medicine study suggests short bursts of nitrites can be beneficial in protecting the heart from stress. The study, researchers said, demonstrated for the first time that short elevations in circulating levels of nitrites are sufficient to have a lasting impact on the heart by modulating its oxidation status and its protein machinery. Nitrite is an oxidation product of the short-lived cell signaling molecule nitric oxide and, until recently, was thought to be...

Chemists at Northwestern University in Evanston, Ill., say two compounds they developed may be effective in protecting against cerebral palsy. The results were just stunning, absolutely amazing, study leader Richard B. Silverman said in a statement. There was a remarkable difference between animals treated with a small dose of one of our compounds and those that were not. The findings, published online in the journal Annals of Neurology, suggest that a preventive strategy for cerebral palsy...
