Lung cancer is the leading cause of cancer death in both men and women. To successfully fight the disease, doctors use a variety of techniques to diagnose the cancer and determine the extent of its spread throughout the body. When using positron emission tomography (PET) as a diagnostic tool, 18F-FDG has proven to be a reliable and accurate tracer, but false positives have been noted in areas of inflammation. Recently, German researchers conducted a study comparing the results of 18F-FDG PET and 18F-

Test for EZH2 protein reveals how aggressive — and deadly — breast tumors will be

U-M, Harvard team shows EZH2 helps cancer cells form colonies and invade tissue

Like a killer charged with more than one murder, a tiny protein that has already been linked to deadly prostate cancer is now being implicated in lethal breast cancer. And it may soon help doctors tell cancer patients just how dangerous their tumors are.

The double-duty offender, called EZH2, appears to hel

New study shows parasitic flatworms take destiny by the tail

In the research article “Larval swimming overpowers turbulent mixing and facilitates transmission of a marine parasite,” appearing in the September issue of the Ecological Society of America’s journal Ecology, Jonathan Fingerut of the University of California-Los Angeles and colleagues describe the results of the first study to examine larval behavior versus passive-transport processes under natural and simulated water

A gel-like material being developed by scientists at the VA Hospital and Washington University in St. Louis could eventually mean the end of bifocals and contacts for millions of middle age and older people who suffer from presbyopia — literally “old vision.” The material, which could be used to replace old hardened lenses in patients, including those with cataracts, was described today at the 226th national meeting of the American Chemical Society, the world’s largest scientific society.

Scientists have known for some time that red wine is healthy for the heart. Now, they have found evidence that provides yet another explanation for this effect.

Scientists at the University of California, Davis, have identified another group of chemicals in red wine that is linked to the ability to lower cholesterol. Called saponins, these glucose-based plant compounds are being found in an increasing number of foods. This is the first time they’ve been found in wine, says Andrew Water

Using MRI scans can help make the diagnosis of multiple sclerosis (MS) more quickly, according to a guideline developed by the American Academy of Neurology. The guideline is published in the September 9 issue of Neurology, the scientific journal of the American Academy of Neurology.

The point at which MS can be diagnosed has been under debate, according to guideline author Elliot Frohman, MD, PhD, of the University of Texas Southwestern Medical School in Dallas.

“Before, the crit
