redOrbit Staff & Wire Reports - Your Universe Online Orange juice contains vitamin C and several other key nutrients, and has also been linked to a reduced risk of obesity in adults, but recently-published research suggests that it could also help prevent cancer. In a review article that was published online last month in Nutrition and Cancer: An International Journal, a team of Brazilian experts presented evidence linking the popular fruit drink with cancer chemoprevention. They...

Giving young children medicine once a month during the rainy season to protect them against malaria could prevent tens of thousands of deaths each year in some areas of Africa, according to new research. A team of scientists analyzed the potential impact of a new strategy to control malaria in Africa which takes a similar approach to that used to protect travelers going to malaria endemic areas and found that even with moderate levels of coverage it could lead to significant public health...

Scientists have identified a biomarker for measuring the success of lung cancer chemoprevention, an emerging frontier in the fight against this disease that has long been stymied by a lack of measureable outcomes. These study results were presented at the AACR 102nd Annual Meeting 2011, held April 2-6. Paul Bunn, M.D., executive director of the International Association for the Study of Lung Cancer and the James Dudley endowed professor of lung cancer research at the University of Colorado...

The popular drug dutasteride may not be a cost-effective way to prevent prostate cancer in men who are at elevated risk of developing the disease, according to findings by a UT Southwestern Medical Center researcher. In a study available in the January issue of Cancer Prevention Research, investigators found that the medication, at an annual cost of $1,400, is impractical when compared to the marginal impact on survival and quality of life in at-risk groups. The drug is indicated for the...

Researchers at Duke University Medical Center have identified a possible biomarker for measuring progress in breast cancer chemoprevention trials, according to data presented at the Ninth Annual AACR Frontiers in Cancer Prevention Research Conference, held here Nov. 7-10, 2010. Although breast cancer treatments are constantly being tested, the progress in chemoprevention has been slower because of a lack of reasonable outcomes that can be measured, according to lead researcher Victoria...

Since the isolation and culture of Helicobacter pylori (H. pylori) in 1983, this bacterium has become accepted as an important human pathogen for the development of gastritis, peptic ulcer, and gastric cancer. Cyclooxgenase-2 (COX-2) is a prostaglandin-synthesizing enzyme. Elevated expression of COX-2 is observed in a wide variety of human malignancies, including gastric cancer. Long-term high dose COX-2 inhibitors can inhibit gastric carcinogenesis in animal models, but the possible...

Once-discarded drug proves effective in pediatric neuroblastoma modelsThe compound, ÃŽ±-difluoromethylornithine or DFMO, targets the activity of a specific enzyme and, even in very limited doses, is effective in protecting against the malignancy in animal models.The study was published in the January 15, 2009 issue of the journal, Cancer Research (Volume 69, Issue 2)."The drug, which was developed as a cancer therapy and later shelved because of toxicity concerns, has been...

New research strongly suggests that a mix of preventative agents, such as those found in concentrated black raspberries, may more effectively inhibit cancer development than single agents aimed at shutting down a particular gene. Researchers at the Ohio State University Comprehensive Cancer Center examined the effect of freeze-dried black raspberries on genes altered by a chemical carcinogen in an animal model of esophageal cancer. The carcinogen affected the activity of some 2,200 genes in...

U.S. cancer researchers say they have developed a chemoprevention gene therapy that successfully kills pancreatic cancer cells. Scientists at Virginia Commonwealth University's Massey Cancer Center and Institute of Molecular Medicine discovered combining a dietary agent with a gene-delivered cytokine effectively eliminates human pancreatic cancer cells in mice. Cytokines are a category of proteins that are secreted into the circulation and can affect cancer cells at distant sites in the...

Recent advances in aerosol-mediated gene delivery have provided the possibility of an alternative...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
