Blueberries may help fight obesity

Recently a study out of the Texas Women's University looked at whether blueberries with their high polyphenol content could help in fighting obesity. Blueberries after all have already been cited as having positive health effects on other conditions like cardiovascular disease and metabolic syndrome. The study was conducted in Petri dishes (not live animals) using a blueberry polyphenol extract and tissue cultures from mice.

Some bacteria avoid antibiotic treatments by going 'off the grid' like rogue secret agents

Going "off the grid," like rogue secret agents, some bacteria avoid antibiotic treatments by essentially shutting down and hiding until it's safe to come out again, says Thomas Wood, professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University.

Signaling pathway reveals mechanism for B cell differentiation in immune response

An article in Science Signaling by researchers at the RIKEN Research Center for Allergy and Immunology (RCAI) has clarified for the first time the mechanism governing differentiation of B cells into antibody-producing plasma cells. The finding establishes a role for the extracellular signal-regulated kinase (ERK) signaling pathway in B cell differentiation, a key step toward the development of B cell-targeted drugs for treatment of autoimmune diseases and allergies.

Canadians join hands in fight against meningitis on April 24th

Canadians can join hands in a virtual community with the Meningitis Research Foundation of Canada and become a member of the global family by visiting www.comoonline.org and "joining hands" in the fight against meningitis, and to show support for meningitis awareness and prevention.

Group B streptococci continues to increase risk of sepsis in newborns

Bloodstream infections in newborns can lead to serious complications with substantial morbidity and mortality. What's more, the pathogens responsible for neonatal infections have changed over time. In recent years, however, antibiotic prophylaxis given to at-risk mothers has reduced the incidence of early-onset group B streptococcal infections among their babies.

Research sheds light on molecular movements of neural transporters

A team of scientists from Columbia University College of Physicians and Surgeons and Weill Cornell Medical College has shed light on the molecular workings of transporter proteins, molecular machines embedded in the cell membranes of neurons that modulate the transfer of signals between cells and recycle neurotransmitters.
