New Study Finds Exposure to Low Levels of Radon Appears to Reduce the Risk of Lung Cancer (3/29/2008)

Exposure to levels of radon gas typically found in 90 percent of American homes appears to reduce the risk of developing lung cancer by as much as 60 percent, according to a study published in the March issue of the journal Health Physics. The finding differs significantly from the results of previous case-control studies of the effects of low-level radon exposure, which have detected a slightly elevated lung cancer risk (but without statistical significance) or no risk at all. ...> Full Article

Review Of Group-Based Cancer Trials Reveals Flaws In Studies' Design And Analysis (3/27/2008)

A new study reviewing 75 group-randomized cancer trials over a five-year stretch shows that fewer than half of those studies used appropriate statistical methods to analyze the results. The review suggests that some trials may have reported that interventions to prevent disease or reduce cancer risks were effective when in fact they might not have been. ...> Full Article

Apple pectin, apple juice extracts shown to have anticarcinogenic effects on colon (3/27/2008)

The apples and apple juice you consume may have positive effects in one of the most unlikely places in the body - in the colon. New research has demonstrated that both apple pectin and polyphenol-rich apple juice components actually enhance biological mechanisms that produce anticarcinogenic compounds during the fermentation process. ...> Full Article

Gene Therapy Can Cause Leukemia In Large Animals (3/26/2008)

Individuals with a number of life-threatening genetic diseases of the immune system have been successfully treated by gene therapy -- that is, they were infused with early precursors of immune cells that had the correct form of the defective gene delivered into them by agents known as retroviral vectors. ...> Full Article

Heart failure treated 'in the brain' (3/26/2008)

Beta-blockers heal the heart via the brain when administered during heart failure, according to a new study by UCL (University College London). Up to now, it was thought that beta-blockers work directly on the heart, but the new study shows that the drugs may also act via the brain, suggesting that future therapies to treat cardiovascular disease could be targeting the central nervous system. ...> Full Article

Impaired sense of smell may be early indicator of Parkinson's disease (3/25/2008)

Impaired sense of smell occurs in the earliest stages of Parkinson's disease (PD) and there is mounting evidence that it may precede motor symptoms by several years, although no large-scale studies had confirmed this. In the first study involving the general population, researchers found that smell impairment can precede the development of PD in men by at least four years. The study is published in the Annals of Neurology, the official journal of the American Neurological Association. ...> Full Article

Scientists see Norwalk virus' Achilles heel (3/25/2008)

Using the Canadian Light Source synchrotron, an international team led by University of Calgary researcher Ken Ng has determined the detailed structure of the enzyme the Norwalk virus uses to make copies of its genetic code in order to replicate itself. The information is crucial to developing drugs that could be used to treat outbreaks of Norwalk and other related viruses. ...> Full Article

Coming soon: Cell therapies for diabetes, cancer? (3/24/2008)

Therapies using stem cell transplants are advancing promising treatments for such conditions as Alzheimer's Disease, neurological diseases and spinal cord injury, and heart disease. Now, scientists think that stem cell transplants may ultimately benefit those who suffer from diabetes or cancer. However, important questions need answers: Given the shortage of human pancreatic islet tissue, can stem cells be used to provide insulin cells that can be stored and secreted from a bioartifical pancreas? Can islet cells be frozen for long periods of time, retain their integrity and be transplanted? If tumors contain cancer stem cells, how can the stem cells be targeted and destroyed to provide improved therapies? ...> Full Article

Researchers unmask proteins in telomerase, a substance that enables cancer (3/22/2008)

One of the more intriguing workhorses of the cell, a protein conglomerate called telomerase, has in its short history been implicated in some critical areas of medicine including cancer, aging and keeping stem cells healthy. With such a resume, telomerase has been the subject of avid interest by basic scientists and pharmaceutical companies alike, so you'd think at the very least people would know what it is. ...> Full Article
