Diets high in salt may increase stomach ulcers

Scientists from the Uniformed Services University of the Health Sciences (USU) have discovered that diets high in salt may increase the virulence of the pathogen Helicobacter pylori (H. pylori), which is the most common cause of ulcers in the stomach and duodenum.

High salt intake increases gene activity in the ulcer-causing bacterium Helicobacter pylori

Scientists have identified yet another risk from a high-salt diet. High concentrations of salt in the stomach appear to induce gene activity in the ulcer-causing bacterium Helicobacter pylori, making it more virulent and increasing the likelihood of an infected person developing a severe gastric disease.

New data on natural probiotic bacterial strain of Bifantis shows anti-inflammatory properties

The biotechnology company Alimentary Health today announced results from two studies that demonstrate the anti-inflammatory activity of a natural probiotic bacterial strain of human origin, Bifantis (Bifidobacterium infantis 35624), in models of arthritis and Salmonella infection.

Culture techniques can significantly affect cell growth and function

When it comes to growing cells in a lab, technique matters. A new Brown University study shows that nerve cells grown in three-dimensional cultures use 1,766 genes differently compared to nerve cells grown in standard two-dimensional petri dishes.

Simple equations track Listeria trails

Circles, slaloms, figure eights, and loop-the-loops , biologists studying the motion of Listeria monocytogenes sensed that these paths were related, but they didn't have a good way to define what fit in and what didn't.

Novel catheter technique for patching holes in the heart

A novel catheter technique for patching holes in the heart may make it possible for many patients to avoid surgery altogether and others to regain enough strength to safely undergo surgical repair at a later date, according to a study reported at the 30th Annual Scientific Sessions of the Society for Cardiovascular Angiography and Interventions.
