Washington, Mar 23 : A new type of yoghurt has been found to be effective against bacteria that cause stomach ulcers, according to a new study.

A type of bacteria called Helicobacter pylori (H. pylori) or over-use of aspirin and or other nonsteroidal antiinflammatory drugs causes most stomach ulcers.

During the study, the research team led by Dr. Hajime Hatta, a chemist at Kyoto Women''s University in Kyoto, Japan, found that H. pylori seems to rely on a protein called urease to attach to and infect the stomach lining.

London, Mar 23: Scientists in the UK have found that a type of drug designed to stunt tumour growth can actually encourage cancer if given at too low a dose.

They looked at angiogenesis inhibitors designed to block the supply of blood to tumours to prevent them from growing.

For their study, the scientists studied an experimental angiogenesis inhibitor called Cilengitide that has yet to be licensed for patients.

In this study, tests conducted on mice showed that low doses of Cilengitide actually stimulated the growth of cancers.

Washington, Mar 23 : Researchers in Canada have found that proteins from a common garden pea could be used as a food additive or new dietary supplement to fight high blood pressure and chronic kidney disease (CKD).

Melbourne, Mar 23 : A new study by University of South Carolina researchers has found that women who work out are three times less likely to die of breast cancer.

The study indicated that aerobically fit women are three times less likely to die of the disease than those who seldom exercise.

For the study, researchers examined 14,000 women who were given preventive medical exams and treadmill tests at the Cooper Clinic in Houston from 1970-2001.

At the time of their exams, the women, ages 20 through 83, had no history of breast cancer.

Hanoi - Vietnamese authorities believe a woman who died last week may have been infected with avian influenza, state media said Monday.

The state-run newspaper Vietnam News reported the 26-year-old woman was admitted to a hospital in Soc Trang Province, in the country's Mekong Delta, on March 16 with symptoms of headache, high fever and respiratory difficulties.

Her condition worsened and she died on Friday.

The head of the community health centre where the patient was initially treated reportedly said she had eaten a sick duck about a month ago.

Washington, Mar 22 : A new study has discovered that if olive oil has been sitting on the shelf for six months, it can lose up to 40 percent of its health benefits.

The research was carried out an analysis on several varieties of extra-virgin olive oil produced from groves in the Italian countryside at production and during storage.

It was discovered that after three months of storage, the antioxidant activity in the oils remained unchanged, but antioxidants decreased by about 40 percent for almost all of the oils after six months.
