Public release date: 29-Oct-2007 DENVER— With suicide as the third leading cause of death among adolescents in the United States, a new University of Denver (DU) study reveals inhaling or “huffing” vapors of common household goods, such as glue or nail polish, are associated with increased suicidal thoughts and attempts. Of the study’s participants, 33 percent reported having inhaled volatile solvents, 25 percent had attempted suicide, and 58 percent reported suicidal thoughts Stacey Freedenthal and Jeffrey M. Jenson of DU’s Graduate School of Social Work joined researchers from Chapel Hill and the University of Pittsburgh in a study of 723 […]
Public release date: 29-Oct-2007 URBANA – The common practice of adding nitrogen fertilizer is believed to benefit the soil by building organic carbon, but four University of Illinois soil scientists dispute this view based on analyses of soil samples from the Morrow Plots that date back to before the current practice began. The research, also drawing upon data from other long-term trials throughout the world, was conducted by U of I soil scientists Saeed Khan, Richard Mulvaney, Tim Ellsworth, and Charlie Boast. Their paper “The Myth of Nitrogen Fertilization for Soil Carbon Sequestration” is published in the November/December 2007 issue […]
Public release date: 30-Oct-2007 The next cancer drug might come straight from the grocery store, according to new research published in the November 2007 issue of The FASEB Journal. In the study, French scientists describe how high and low doses of polyphenols have different effects. Most notably, they found that very high doses of antioxidant polyphenols shut down and prevent cancerous tumors by cutting off the formation of new blood vessels needed for tumor growth. Polyphenols are commonly found in red wine, fruits, vegetables, and green tea. At relatively low doses, the French researchers found that the same polyphenols play […]
Rosemary not only tastes good in culinary dishes such as Rosemary chicken and lamb, but scientists have now found it is also good for your brain. A collaborative group from the Burnham Institute for Medical Research (Burnham Institute) in La Jolla, CA and in Japan, report that the herb rosemary contains an ingredient that fights off free radical damage in the brain. The active ingredient in rosemary, known as carnosic acid (CA), can protect the brain from stroke and neurodegeneration that is due to injurious chemical free radicals. These radicals are thought to contribute not only to stroke and neurodegenerative […]
Public release date: 2-Oct-2007 Hamilton, ON (Oct. 1, 2007) – Lower muscle mass and an increase in body fat are common consequences of growing older. While exercise is a proven way to prevent the loss of muscle mass, a new study led by McMaster researcher Dr. Mark Tarnopolsky shows that taking a combination of creatine monohydrate (CrM) and conjugated linoleic acid (CLA) in addition to resistance exercise training provides even greater benefits. The study to be published on Oct. 3 in PLoS One, an international, peer-reviewed online journal of the Public Library of Science, involved 19 men and 20 women […]
Public release date: 2-Oct-2007 Swedish researchers have discovered that oseltamivir (Tamiflu); an antiviral drug used to prevent and mitigate influenza infections is not removed or degraded during normal sewage treatment. Consequently, in countries where Tamiflu is used at a high frequency, there is a risk that its concentration in natural waters can reach levels where influenza viruses in nature will develop resistance to it. Widespread resistance of viruses in nature to Tamiflu increases the risk that influenza viruses infecting humans will become resistant to one of the few medicines currently available for treating influenza The Swedish research group demonstrated that […]
Public release date: 3-Oct-2007 Drugs called anthracyclines are a breast cancer chemo staple despite a well-known risk: They weaken some women’s hearts. What’s new is research suggesting the drugs work no better than safer alternatives for most women. It’s a controversy born of success: Treatment advances are enabling more women than ever before to beat breast cancer, and some 2.4 million survivors are alive today. Now a move is underway to determine just how many women are vulnerable to heart disease because of their cancer battle, and how to help them. Dr. Dennis Slamon of UCLA’s Jonsson Cancer Center cites […]
Public release date: 5-Oct-2007 DANVILLE, PA. – Workers who have diabetes with neuropathic symptoms such as numbness or tingling in feet or hands lose the equivalent of 1.4 hours a week or $3.65 billion per year in health-related lost productive time, a recent study finds Geisinger Center for Health Research investigators looked at 19,075 working adults, including 1,003 who were diagnosed with diabetes. Of these workers, 38% reported diabetes-related numbness or tingling in their feet or hands Those with diabetes were about twice more likely than those without diabetes to be unemployed.

Public release date: 5-Oct-2007 The research, which involved three separate studies and a follow-up, is discussed in “The Calcium Quandary: How Consumers Use Nutrition Labels for Daily Diet,” published in the Journal of Public Policy and Marketing. Peracchio and Block found that: In Study 1, only two of 37 respondents correctly translated the calcium information on a carton of yogurt from %DV to milligrams. In Study 2, when 20 physicians were shown the same label, only six gave the right answer in milligrams. (Asked how the calculation was done, one physician who gave an incorrect answer replied: “I have no […]
Public release date: 8-Oct-2007 Eating fewer refined carbohydrates may slow the progression of age-related macular degeneration (AMD), according to a new study from researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University. AMD results in partial or total blindness in 7 to 15% of the elderly, according to the Eye Diseases Prevalence Research Group. “Dietary changes may be the most practical and cost-effective prevention method to combat progression of AMD,” says Allen Taylor, PhD, director of the Laboratory for Nutrition and Vision Research at the USDA HNRCA. “It is surprising there is so little […]
Public release date: 8-Oct-2007 PORTLAND, Ore. – In a study of the maternity records of more than 6,000 women, David J.P. Barker, M.D., Ph.D., and Kent Thornburg, Ph.D., of Oregon Health & Science University discovered a strong correlation between the size and shape of a woman’s hips and her daughter’s risk of breast cancer. Wide, round hips, the researchers postulated, represent markers of high sex hormone concentrations in the mother, which increase her daughter’s vulnerability to breast cancer. The study, carried out with colleagues in Finland and the United Kingdom., is described in an article just published online by the […]
Public release date: 8-Oct-2007 October 8, 2007 — A new study by researchers at Columbia University Mailman School of Public Health finds that folic acid supplements can dramatically lower blood arsenic levels in individuals exposed to arsenic through contaminated drinking water. This toxic element, naturally present in some aquifers used for drinking, is currently a significant public health problem in at least 70 countries, including several developing countries and also parts of the U.S. Chronic arsenic exposure is associated with increased risk for skin, liver and bladder cancers, skin lesions, cardiovascular disease, and other adverse health outcomes. The study results […]
Public release date: 8-Oct-2007 WINSTON-SALEM, N.C. – New research shows that selective serotonin reuptake inhibitors (SSRIs), a group of drugs commonly used to treat depression, may double the risk of gastrointestinal bleeding, according to researchers from Wake Forest University School of Medicine and colleagues. When the drugs are taken with aspirin and other similar pain medications, the risk is more than 600 percent higher. “Clinicians who prescribe these medications should be aware of the potential risk and may need to consider alternatives,” said Sonal Singh, M.D., senior researcher and an assistant professor of internal medicine. “In addition, regulatory authorities should […]
Public release date: 8-Oct-2007 DURHAM, N.C. – Long denigrated as vestigial or useless, the appendix now appears to have a reason to be – as a “safe house” for the beneficial bacteria living in the human gut. Drawing upon a series of observations and experiments, Duke University Medical Center investigators postulate that the beneficial bacteria in the appendix that aid digestion can ride out a bout of diarrhea that completely evacuates the intestines and emerge afterwards to repopulate the gut. Their theory appears online in the Journal of Theoretical Biology. The gut is populated with different microbes that help the […]
Public release date: 9-Oct-2007 The use of androgen deprivation therapy to treat localized prostate cancer is associated with an increased risk of death from heart disease, according to a study published online October 9 in the Journal of the National Cancer Institute Androgen deprivation therapy is frequently used to treat high-risk localized prostate cancer. Studies have shown that androgen deprivation therapy, when used with external beam radiation therapy, improves survival in patients with advanced and localized prostate cancer. But the use of androgen deprivation therapy can also lead to the development of metabolic syndrome, which increases the risk of type […]
Public release date: 10-Oct-2007 It is relatively rare for an influenza virus to be virulent enough to cause death in healthy humans. Many deaths associated with influenza are caused by the combined influence of viral disease and the following secondary bacterial infection. Although the 1918 pandemic strain was one of the few influenza viruses capable of killing healthy victims on its own, the majority of fatal cases from the “Spanish Flu” can be attributed to secondary bacterial pathogens rather than primary viral disease. This important interaction between influenza viruses and bacteria is not well understood. Dr. Jonathan A. McCullers from […]
Public release date: 10-Oct-2007 Young women suffering from breast cancer do not necessarily benefit from chemotherapy treatment Women under the age of forty with breast cancer who are given drugs in addition to lumpectomies or radiotherapy, known as adjuvant chemotherapy, may not be benefiting from these drugs. This is especially true if their tumors respond to changing levels of hormones such as estrogen, according to research published in the online journal, Breast Cancer Research. “Developing breast cancer at a young age is very worrying in terms of survival,” explained lead researcher Dr J van der Hage. “But some young women […]
Public release date: 10-Oct-2007 Obese people are six times as likely to develop gullet (oesophageal) cancer as people of ‘healthy’ weight, shows research published ahead of print in the journal Gut. Rates of oesophageal cancer have been rising rapidly, and in some countries, they have risen faster than those of every other major cancer, say the authors The link between acid reflux and gullet cancer is well known, and unsurprisingly, repeated symptoms of severe heartburn or gastrointestinal reflux disease (GORD) were associated with a much higher risk of the cancer GORD quintupled the risk of oesophageal cancer, and a combination […]
Public release date: 10-Oct-2007 COLUMBIA, Mo. – Red wine is known to have multiple health benefits. Researchers at the University of Missouri-Columbia have found that red wine may also protect humans from common food-borne diseases Researchers Azlin Mustapha, associate professor of food science in the College of Agriculture, Food and Natural Resources, and Atreyee Das, a doctoral student in the food science program, are conducting on-going studies examining the inhibitory effects of numerous types of red wines, as well as grape juice, against pathogens and probiotic bacteria, which naturally reside in the intestinal tract and can be beneficial in combating, […]
Public release date: 11-Oct-2007 New research from Northwestern University’s Feinberg School of Medicine has found that nearly 50 percent of patients taking antihypertensive drugs in three community health centers were unable to accurately name a single one of their medications listed in their medical chart. That number climbed to 65 percent for patients with low health literacy. “It was worse than we expected,” said lead author Stephen Persell, M.D., an assistant professor of medicine, and of the Institute for Healthcare Studies at the Feinberg School, and a physician at Northwestern Memorial Hospital. “It means doctors can’t ask patients to tell […]
