Available lines of human embryonic stem cells have been contaminated

Currently available lines of human embryonic stem cells have been contaminated with a non-human molecule that compromises their potential therapeutic use in human subjects, according to research by investigators at the University of California, San Diego (UCSD) School of Medicine and the Salk Institute in La Jolla, California.

Heart patients with gastrointestinal complications should use low doses of aspirin combined with drugs that treat stomach ulcers

Physicians are challenged in treating heart patients who may be at high-risk for gastrointestinal bleeding from aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs). Factors that place patients at high-risk include a history of ulcers or gastrointestinal complications such as bleeding, increased age and congestive heart failure.

Chronic users NSAIDs have greater risk of bleeding and visible damage to their small intestine

According to a study published today in the American Gastroenterological Association (AGA) journal Clinical Gastroenterology and Hepatology, chronic users of non-steroidal anti-inflammatory drugs (NSAIDs) have an increased risk of bleeding and visible damage to their small intestine.

Does cancer run in families?

If you have a relative with cancer, probably one of the most pressing questions is what your chances are of getting it yourself. In a paper published in PloS Medicine, the premier medical journal freely available online, Laufey Amundadottir and colleagues from deCODE genetics (a company that is using genetics to develop new drug treatments) and Iceland’s National-University Hospital go some way toward answering that question.

Stem cells' repair skills could be link to cancer

Johns Hopkins researchers say there is growing evidence that stem cells gone awry in their efforts to repair tissue damage could help explain why long-term irritation, such as from alcohol or heartburn, can create a breeding ground for certain cancers.

Transport route explain why peanuts are one of the most allergenic foods

A UK scientist has discovered the route and type of transport taken by peanut proteins through the gut to the immune system. This route favours an immune response, which helps explain why peanuts are one of the most allergenic foods.

World’s strongest acid may have a role in synthesizing pharmaceuticals

Researchers at the University of California, Riverside have discovered the world’s strongest acid. Remarkably it is also the gentlest acid. This non-toxic and non-corrosive acid may have a role in processes such as improving the quality of gasoline, developing polymers and synthesizing pharmaceuticals.
