Brett Smith for redOrbit.com - Your Universe Online A new study presented on Sunday at the annual meeting of the American Society for Microbiology has found that the same bacteria responsible for gum disease can also advance heart disease. While doctors recognize that individuals with gum disease are at greater risk for heart disease, gum disease isn't currently considered a standard risk factor for heart disease. "We report evidence that introduction of oral bacteria into the...

New research published in the Journal of Leukocyte Biology suggests that Porphyromonas gingivalis causes excess IL-10 production, which inhibits the immune cells interferon gamma leading to infection A new research report published in the Journal of Leukocyte Biology shows how the bacteria known for causing gum disease--Porphyromonas gingivalis--manipulates the body's immune system to disable normal processes that would otherwise destroy it. Specifically, the report shows that this...

Bacteria May Signal Risk For Pancreatic Cancer

Pancreatic cancer is highly lethal and difficult to detect early. In a new study, researchers report that people who had high levels of antibodies for an infectious oral bacterium turned out to have double the risk for developing the cancer. High antibody levels for harmless oral bacteria, meanwhile, predicted a reduced pancreatic cancer risk. A new study finds significant associations between antibodies for multiple oral bacteria and the risk of pancreatic cancer, adding support for the...

Research could pave the way for preventative measures to tackle gum disease Normal bacteria which live in our mouths provide the catalyst for the development of gum disease, a debilitating condition which leads to painful gums and the loosening of teeth, new research from Queen Mary, University of London has found. The unexpected finding could pave the way for the development of preventative measures in tackling gum, or periodontal disease*, by manipulating the normal bacteria in the...

Atherosclerosis is the leading cause of death in the developed world. While a number of risk factors for atherosclerosis have been defined, scientists continue to study other possible risk factors for this disease. Recent epidemiological and experimental studies link infectious agents with the development of inflammatory atherosclerosis. A hallmark of chronic infection with the oral pathogen Porphyromonas gingivalis is the induction of a chronic inflammatory response. P. gingivalis induces a...

STOCKHOLM, November 10, 2010 /PRNewswire-FirstCall/ -- The study shows that L. reuteri Prodentis acts synergistically with standard treatment (scaling and root plaining, SRP) to significantly reduce probing pocket depth (PPD) and clinical attachment level (CAL) which are the two most important parameters to assess the severity of periodontitis. Furthermore L. reuteri Prodentis reveals - as the first probiotic ever - significant reductions of three different pathogens in patients with...

Today during the 88th General Session & Exhibition of the International Association for Dental Research, in Barcelona, Spain, presenting author J. Meyle, Justus Liebig University, Giessen, Germany, will present an abstract titled "P. gingivalis Infection and Immune Evasion of Oral Carcinomas." Meyle and his team are investigating the relationship of oral cancers and periodontal disease. They achieved results by infecting cell carcinoma cells SCC-25 with Porphyromonas gingivalis (P.g.)...

A defective, mutant strain of the bacterium that causes gum disease could provide a clue to potential treatments for Alzheimer's, Parkinson's and a number of other diseases. Researchers from the University of Florida College of Dentistry reported their findings May 25 at the 110th General Meeting of the American Society for Microbiology in San Diego. Autophagy, or "self-eating," is an essential component of cellular survival and defense against invading organisms. It is how the cell degrades...

A new study indicates that there may be a link between good oral care and aging adults retaining their mental sharpness, reported Reuters. Researchers found during the study that adults aged 60 and older with the highest versus the lowest levels of the gum disease-causing pathogen Porphyromonas gingivalis were three times more likely to have a hard time remembering a three-word sequence after a period of time. Dr. James M. Noble of Columbia College of Physicians and Surgeons in New York City...

Scientists in the USA have discovered why smokers may be more prone to chronic gum disease (periodontitis). One of the bacteria responsible for this infection responds to cigarette smoke "“ changing its properties and the way it infects a smokers mouth. The study published recently in the Society for Applied Microbiology journal Environmental Microbiology, showed that the bacterium Porphyromonas gingivalis adapts and changes its DNA and membrane proteins in response to cigarette smoke....


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED.
