New Method Gives Ulcer Test Green Light
Doctors may soon be able to diagnose stomach ulcers without taking tissue samples from the stomach. Researchers from the Univ. of Southern Denmark have developed a new, safer and noninvasive diagnostic technique for ulcers. The trick is to make the ulcer-causing bacteria in the gut light up in fluorescent green.
Each year, many patients are examined for ulcers, and this is often done by retrieving a tissue sample from the stomach. This requires that the doctor sends an instrument down into the patient´s stomach, and the patient must wait for the tissue sample to be analyzed before the doctor can give information about a possible ulcer.

A new strain of stomach bug sweeping the globe is taking over in the U.S., health officials say. Since September, more than 140 outbreaks in the U.S. have been caused by the new Sydney strain of norovirus. It may not be unusually dangerous; some scientists don’t think it is. But it is different, and many people might not be able to fight off its gut-wrenching effects.
Clearly, it’s having an impact. The new strain is making people sick in Japan, Western Europe and other parts of the world. It was first identified last year in Australia and called the Sydney strain. In the U.S., it is now accounting for about 60 percent of norovirus outbreaks, according to report released by the Centers for Disease Control and Prevention.

X-rays Pinpoint Drug Target for Stomach Ulcers
Experiments at the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory have revealed a potential new way to attack common stomach bacteria that cause ulcers and significantly increase the odds of developing stomach cancer.
The breakthrough, made using powerful X-rays from SLAC’s Stanford Synchrotron Radiation Lightsource (SSRL), was the culmination of five years of research into the bacterium Helicobacter pylori, which is so tough it can live in strong stomach acid. At least half the world’s population carries H. pylori and hundreds of millions suffer health problems as a result; current treatments require a complicated regimen of stomach-acid inhibitors and antibiotics.

U.S. Tap Water Causes 1 M Cases of Stomach Illness Per Year
The distribution system piping in U.S. public water systems that rely on non-disinfected well water or “ground water” may be a largely unrecognized cause of up to 1.1 million annual cases of acute gastrointestinal illness (AGI), involving nausea, vomiting and diarrhea, scientists are reporting. Their study in ACS’ journal Environmental Science & Technology concludes that such illnesses may become more of a problem as much of the nation’s drinking water supply system continues to age and deteriorate.
Frank Loge and Mark Borchardt, from UC Davis, and their colleagues explain that more than 100 million people in the U.S. rely on water piped into homes, schools and businesses from public water systems that get their water from wells, rather than lakes, rivers and other above-ground sources. Much of that water either is not disinfected at all or is not adequately disinfected to kill disease-causing viruses.

Birds’ Stomachs Show Extreme Plastic Pollution Levels
Plastic pollution off the northwest coast of North America is reaching the level of the notoriously polluted North Sea, according to a new study led by a researcher at the Univ. of British Columbia.
The study, published online in the journal Marine Pollution Bulletin, examined stomach contents of beached northern fulmars on the coasts of British Columbia, Canada and the states of Washington and Oregon.

Pigs’ Stomach Mucus Could Make Safer Baby Formula
Scientists are reporting that the mucus lining the stomachs of pigs could be a long-sought, abundant source of “mucins” being considered for use as broad-spectrum anti-viral agents to supplement baby formula and for use in personal hygiene and other consumer products to protect against a range of viral infections. Their study appears in ACS’ journal Biomacromolecules.
