Early switch to an aromatase inhibitor increases survival

For breast cancer patients taking tamoxifen, switching to an aromatase inhibitor within three years significantly improves survival rates, according to a new study. Published in the March 15, 2007 issue of CANCER (http://www.interscience.wiley.com/cancer-newsroom), a peer-reviewed journal of the American Cancer Society, the study reveals that the clear survival benefit was also achieved without an increased risk of death from other causes – a significant risk associated with tamoxifen. more  

New potential health benefit of olive oil for peptic ulcer disease

Already fabled for an array of health benefits, extra virgin olive oil — a centerpiece of the Mediterranean Diet — may have a new role in helping to prevent and treat Helicobacter pylori (H. pylori) infections, which cause millions of cases of gastritis and peptic ulcer disease each year, researchers in Spain report. more

A healthier glass of wine?

A new technique that uses ozone to preserve grapes could help prevent allergies and boost healthy compounds at the same time, reports Jennifer Rohn in Chemistry & Industry, the magazine of the SCI. The same technique could be used in the wine-making process to produce healthier wines without the added sulphites that can cause asthma and other conditions in some people. more  

Extra cortisol protects women's mood under stress

German researchers have found additional evidence that the stress hormone cortisol can have positive effects in certain situations. Although chronic stress, which brings long-term elevations of cortisol in the bloodstream, can weaken the immune system and induce depression, this new study adds to mounting evidence that cortisol given near in time to a physical or psychological stress may lessen the stressor's emotional impact. more

New mechanism for nutrient uptake discovered  

Biologists at the Carnegie Institution's Department of Plant Biology have discovered a new way that plant cells govern nutrient regulation—neighboring pore-like structures at the cell's surface physically interact to control the uptake of a vital nutrient, nitrogen. It is the first time scientists have found that the interaction of neighboring molecules is essential to this regulation. Since plants, animals, bacteria, and fungi all share similar genes for this activity, the scientists believe that the same feature could occur across species. more

Possible solution to Group B streptococci infection in newborn infants  

The search for a vaccine against group B streptococci Group B streptococci are one of the leading causes of infection in newborn infants, causing pneumonia, septicaemia or meningitis. A group of Portuguese researchers and a team in a CNRS-associated laboratory at the Institut Pasteur have just identified a protein in this micro-organism which allows it to colonise a host by modulating its immune system. According to these scientists, who have published this study in the Journal of Immunology, the protein thus identified is a possible candidate for the development of a vaccine against Group B Streptococci. more

Smell may outlast other senses

About 1000 Australian males and females of all ages were tested for their ability to detect or identify a range of different odors at different concentrations, and then given an overall score for their sense of smell, or olfactory function. more
