Markus Neurath and fellow researchers at the University of Mainz, Germany, have characterized the interaction between intestinal bacteria and dendritic cells (DCs) that may provide an explanation for the clinical symptoms of Crohn disease that only occur in specific regions of the gut.

The authors used transgenic mice to investigate the expression of the p40 subunit of IL-12 and IL-23. The authors demonstrate that p40 is expressed by a newly identified subset of DCs at greater levels in the

The latest discovery of a large asteroid moving through our Solar System puts a spotlight on the studies of these and other wandering celestial objects by the European Space Agency.

Some astronomers have predicted that this newly discovered object could hit the Earth on 21 March, 2014, but now data indicate that the chances of it doing so are really very small – less than one in 909,000.

However, scientists continue to monitor these objects which could give clues to the orig

“Virtual product demonstrations that allow individuals to interact with merchandise create more vivid mental images of the consumer using the products, thereby increasing the likelihood they’ll purchase the item,” said Ann Schlosser, UW Business School assistant professor of marketing.

“We’ve found that the more easily individuals can envision themselves using a product, the more likely they are to buy it.”

Schlosser studied how consumer

When physicians routinely “thin” the blood of patients undergoing coronary artery bypass surgery in order to place them on the heart-lung machine, they may be causing more damage to the kidneys and other organs than previously appreciated, according to a new study by Duke University Medical Center researchers.

For years moderate dilution of the blood has been thought to protect the kidneys from damage, but the Duke researchers found in their study of more than 1,400 bypass patients that dil

On October 13, 2003 the European Bioinformatics Institute (EBI) will launch a new bioinformatics support network that is tailor-made for small companies.

It can be a lonely business being a bioinformatician in a small company. It is widely acknowledged that Europe’’s economic development is becoming increasingly dependent on small-to-medium enterprises, or SMEs (enterprises with fewer than 250 employees and an annual turnover not exceeding 50 million Euros or an annual bala

ESC Congress 2003: Picture Perfect – Progress in non-invasive imaging

There has been increasing awareness of the importance of composition of athero-thrombotic plaque as a major risk factor for acute coronary syndromes. Several invasive and noninvasive imaging techniques are available to assess athero-thrombotic vessels.

Most of the standard techniques identify luminal diameter or stenosis, wall thickness, or plaque volume (such as multi-slice CT, angiography, IVUS, etc.); h
