Fluoride has dramatic effects on bacteria inside the mouth

Regular use of fluoride-containing toothpaste and mouthwash has long been known to strengthen the enamel on teeth. But new research by Howard Hughes Medical Institute (HHMI) scientists finds that fluoride also has dramatic effects on bacteria inside the mouth -- including those that form plaque and can cause cavities.

Researchers develop CAD-type tools to engineer RNA control systems

The computer assisted design (CAD) tools that made it possible to fabricate integrated circuits with millions of transistors may soon be coming to the biological sciences. Researchers at the U.S. Department of Energy (DOE)'s Joint BioEnergy Institute (JBEI) have developed CAD-type models and simulations for RNA molecules that make it possible to engineer biological components or "RNA devices" for controlling genetic expression in microbes.

Hand washing tips to prevent illness and spreading germs

With holiday gatherings, New Year celebrations, and constant travelling, hand washing is one of the most important ways to prevent getting sick and spreading germs. Many illnesses, including the common cold, are spread by not washing hands properly with soap and water. According to statistics from the National Library of Medicine, the common cold accounts for approximately 22 million missed days of school and 20 million absences from work.

Azithromycin shows promise against trachoma-related blindness

A UCSF study shows a popular treatment for a potentially blinding eye infection is just as effective if given every six months versus annually. This randomized study on trachoma, the leading cause of infection-caused blindness in the world, could potentially treat twice the number of patients using the same amount of medication.

Large-intestine bacteria may help prevent obesity

Bacteria living in people's large intestine may slow down the activity of the "good" kind of fat tissue, a special fat that quickly burns calories and may help prevent obesity, scientists are reporting in a new study.

Bacteria use host proteins to build camouflaged homes inside healthy cells

Bacteria are able to build camouflaged homes for themselves inside healthy cells - and cause disease - by manipulating a natural cellular process.

Hi-tech dental instrument uses 'cool flame' for painless fillings

University of Missouri engineers and their research collaborators at Nanova, Inc. are one step closer to a painless way to replace fillings. After favorable results in the lab, human clinical trials are underway on the "plasma brush."

More evidence emerges to support that progenitor of syphilis came from the New World

Skeletons don't lie. But sometimes they may mislead, as in the case of bones that reputedly showed evidence of syphilis in Europe and other parts of the Old World before Christopher Columbus made his historic voyage in 1492.

Study examines relationship between malaria, salmonella infection

People with malaria are more prone to developing bacterial infections, particularly from salmonella, and "researchers at the London School of Hygiene & Tropical Medicine [LSHTM] have discovered that the increased vulnerability to salmonella infections is a side effect of the body's attempts to protect itself from the damaging effects of the malaria infection," according to an LSHTM press release.

Eculizumab protects children from severe Shiga toxin-associated HUS

A physician and researcher at the Sainte Justine University Hospital Center (Sainte-Justine UHC), a University of Montreal affiliate, saved the life of a child and, by doing so, became the first to find a new use for a drug in the fight against deadly E. coli bacteria.

New gel could nip Lyme borreliosis infection in the bud

They come out in the spring, and each year they spread further - the ticks. Thirty percent of them transmit borrelia pathogens, the causative agent of Lyme borreliosis that can damage joints and organs.

F. nucleatum alters endothelial integrity and allows other bacteria to invade human body

A common oral bacteria, Fusobacterium nucleatum, acts like a key to open a door in human blood vessels and leads the way for it and other bacteria like Escherichia coli to invade the body through the blood and make people sick, according to dental researchers at Case Western Reserve University.

Poor handling of oranges in squeezing machines stimulates bacterial contamination

Scientists from the University of Valencia in Spain have analysed fresh orange juice squeezed by machines in catering establishments. They have confirmed that 43% of samples exceeded the acceptable enterobacteriaceae levels laid down by legislation. The researchers recommend that oranges are handled correctly, that juicers are washed properly and that the orange juice is served immediately rather than being stored in metal jugs.
