PLOS How P. gingivalis causes chronic inflammation in blood vessels Chronic oral infection with the periodontal disease pathogen, Porphyromonas gingivalis, not only causes local inflammation of the gums leading to tooth loss but also is associated with an increased risk of atherosclerosis. A study published on July 10th in PLOS Pathogens now reveals how the pathogen evades the immune system to induce inflammation beyond the oral cavity. Like other gram-negative bacteria, P....

Obesity, Gut Bacteria Link Found In People Who Live In Cold Climates
2014-02-12 15:23:43

Lee Rannals for redOrbit.com - Your Universe Online People who live in colder climates have adapted to the harsher conditions by adding a gut bacteria associated with obesity. Humans have a gut full of bacteria to help digest food and past studies have linked an increase in the proportion of bacteria from the Firmicutes group to obesity and a decrease in the proportion from the Bacteroidetes group. The research, published in the Royal Society Journal Biology Letters, says that this...

Scientists Discover Why Smokers Gain Weight When They Quit

Enid Burns for redOrbit.com – Your Universe Online Many smokers don't want to quit because they are afraid of the weight gain that comes with putting out the cigarette. New findings from the Swiss National Science Foundation show that it's not higher calorie intake, but a change in the composition of intestinal flora. Researchers find that about 80 percent of smokers put on an average of seven kilograms, or about 15 pounds. "Their weight increases even if their calorie intake remains...

Implications for development of immune system and allergies, say researchers The range of helpful bacteria in the guts of infants delivered by caesarean section, during their first two years of life, is narrower than that of infants delivered vaginally, indicates a small study published online in the journal Gut. This has implications for the development of the immune system, say the researchers, particularly as the C-section infants had lower levels of the major group of gut bacteria...

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...

Michael Harper for redOrbit.com — Your Universe Online It´s time once again to look to a 90s Romantic Comedy for sage advice to guide us through our every day lives. In the words of Janeane Garofalo in the 1996 movie “The Truth About Cats and Dogs,” “You can love your pets, but just don´t LOVE your pets.” Another lesson learned from this film: Be yourself. Don´t try to be Uma Thurman. It seems the latest from the journal Archives of...

Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, finds that gastric bypass surgery induces changes in the gut microbiota and peptide release that are similar to those seen after treatment with prebiotics. Previous animal research demonstrated that ingestion of a high-fat diet produces weight gain and profoundly affects the gut microbiota composition,...

Microorganisms in the human gastrointestinal tract form an intricate, living fabric made up of some 500 to 1000 distinct bacterial species, (in addition to other microbes). Recently, researchers have begun to untangle the subtle role these diverse life forms play in maintaining health and regulating weight. In a new study appearing in the journal Nutrition in Clinical Practice, researcher Rosa Krajmalnik-Brown and her colleagues at the Swette Center for Environmental Biotechnology at...

"You are what you eat" is familiar enough, but how deep do the implications go? An interdisciplinary group of investigators from the Perelman School of Medicine at the University of Pennsylvania have found an association between long-term dietary patterns and the bacteria of the human gut. In a study of 98 healthy volunteers, the gut bacteria separated into two distinct groups, called enterotypes, that were associated with long-term consumption of either a typical Western diet rich in meat...

The human gut is filled with 100 trillion symbiotic bacteria"”ten times more microbial cells than our own cells"”representing close to one thousand different species. "And yet, if you were to eat a piece of chicken with just a few Salmonella, your immune system would mount a potent inflammatory response," says Sarkis K. Mazmanian, assistant professor of biology at the California Institute of Technology (Caltech). Salmonella and its pathogenic bacterial kin don't look that much...
