Ulcer-causing bacteria baffled by mucus (1/31/2012)

Ulcer-causing bacteria baffled by mucusResearchers at Rensselaer Polytechnic Institute have discovered how certain polymers -- like those found in human mucus and saliva -- make it significantly more difficult for ulcer-causing bacteria to coordinate. The findings raise many new questions about the relationship between the individual and group behaviors of bacteria. The study also suggests that human mucus, saliva, and other biological fluid barriers may have evolved to disrupt the ability of harmful bacteria to coordinate. ...> Full Article

How protein networks stabilize muscle fibers: Same mechanism as for DNA (1/26/2012)

The same mechanism that stabilizes the DNA in the cell nucleus is also important for the structure and function of vertebrate muscle cells. This has been established by RUB researchers in cooperation with American and German colleagues. An enzyme attaches a methyl group to the protein Hsp90, which then forms a complex with the muscle protein titin. When the researchers disrupted this protein network through genetic manipulation in zebrafish the muscle structure partly disintegrated. ...> Full Article

In a study conducted among 25 healthy individuals living in a controlled setting who were randomized to overconsumption of different levels of protein diets, those consuming the low-protein diet had less weight gain compared to those consuming normal and high protein diets, and calories alone, and not protein appeared to contribute to an increase in body fat, according to a study in the Jan. 4 issue of JAMA. ...> Full Article


Scientists link dietary DHA to male fertility (1/11/2012)

A University of Illinois study reports that a certain omega-3 fatty acid is necessary to construct the arch that turns a round, immature sperm cell into a pointy-headed super swimmer with an extra long tail. The study shows that docosahexaenoic acid is essential in fusing the building blocks of the acrosome together. The acrosome is critical in fertilization because it houses, organizes, and concentrates a variety of enzymes that sperm use to penetrate an egg. ...> Full Article
