The research could lead to advanced therapies for patients with dry mouth University of Louisville researchers are one step closer to helping millions of people whose salivary glands no longer work because of disease or damage from treatment of diseases. The scientific finding of Douglas Darling, PhD, professor, Department of Oral Health and Rehabilitation, UofL School of Dentistry, and his team identified a protein sorting mechanism used by the salivary gland. The National Institutes of...

When it comes to breaking down plant matter and converting it to energy, the cow has it all figured out. Its digestive system allows it to eat more than 150 pounds of plant matter every day. Now researchers report that they have found dozens of previously unknown microbial enzymes in the bovine rumen "“ the cow's primary grass-digestion chamber "“ that contribute to the breakdown of switchgrass, a renewable biofuel energy source. The study, in the journal Science, tackles a major...

The types of gut bacteria that populate the guts of primates depend on the species of the host as well as where the host lives and what they eat. A study led by Howard Ochman at Yale University examines the gut microbial communities in great apes, showing that a host's species, rather than their diet, has the greatest effect on gut bacteria diversity. These findings will publish next week in the online, open access journal PLoS Biology. "Bacteria are crucial to human health. They enhance the...

For the first time ever, University of Illinois researchers have discovered how microbes break down hemicellulose plant matter into simple sugars using a cow rumen bacterium as a model. "This is ground-breaking research," said Isaac Cann, associate professor in the U of I Department of Animal Sciences and member of the Energy Biosciences Institute (EBI) in the Institute for Genomic Biology. "The implications are very broad, yet it all started with a simple rumen microbe. It's amazing how we...

Step towards designing fats that are digested more slowly Institute of Food Research scientists have discovered an unexpected synergy that helps break down fat. The discovery provides a focus to find ways to slow down fat digestion, and ultimately to create food structures that induce satiety. "Much of the fat in processed foods is eaten in the form of emulsions such as soups, yoghurt, ice cream and mayonnaise,"" said Dr Peter Wilde from the Institute of Food Research, an institute of BBSRC....

We are what we eat, but who are "we"? New, high-powered genomic analytical techniques have established that as many as 1,000 different single-celled species coexist in relative harmony in every healthy human gut. "For each human cell in your body there are 10 microbial cells, most of them living in the gut and helping us digest things we can't digest on our own," said Justin Sonnenburg, PhD, assistant professor of microbiology and immunology at the Stanford University School of Medicine. "In...

Researchers have discovered that a marine germ typically found on the seaweed used to wrap sushi interacts with internal bacteria in our bodies and helps with the digestive process. According to a group of scientists from the National Centre for Scientific Research (CNRS) in Roscoff, France, an enzyme known as porphyranase helps break down carbohydrates in the cell walls of Porphyra, a red algae that is the main ingredient of the nori sheets used to wrap sushi. The enzyme was also discovered...

The human gut is a breeding ground - in a good way - for a wide variety of bacteria, according to a new study. An international effort to catalog millions of non-human genes found inside people, found more than 170 different bacteria species living in the average person's digestive system. The study also found that people with inflammatory bowel disease had fewer unique species than healthier people. More than 99 percent of all the different gene types in the human body are not even human,...

The natural-occurring biopolymer known as chitosan is being put forward as an effective alternative to growth-promoting antibiotics in the diet of ruminants, according to research carried out by scientists at the Basque technological center, Neiker-Tecnalia. The presence of these antibiotics as additives in the diet of ruminants has been prohibited in the European Union since 2006, given that their use is linked to developing microbial resistance to antibiotics. The main problem arising from...

Scientists have crystallised a protein that may help gut bacteria bind to the gastrointestinal tract. The protein could be used by probiotic producers to identify strains that are likely to be of real benefit to people. "Probiotics need to interact with cells lining the gut to have a beneficial effect, and if they attach to surfaces in the gut they are more likely to stick around long enough to exert their activity," says Dr Nathalie Juge from the Institute of Food Research. IFR is an...

Large Intestine
2013-04-30 14:11:04

The large intestine is the organ that follows the small intestine but is the last part of the digestive tract before the waste leaves the body. Formation and Orientation The small intestine is on average about five feet long. It is composed of four distinct structural parts; the cecum, colon, and anus. The cecum is the part of the large intestine that comes first. It is separated into three parts. The taeniae coli are three bands of smooth muscle. The haustra are bulges caused by...

Mouth
2013-03-05 14:37:32

The mouth is the beginning of the digestive system which takes in food and mixes it with saliva produced by glands located in the mouth. Formation and Orientation The first part of the mouth is the mouth cavity which contains the teeth and is limited by the lips, the roof, which is the hard and soft palate, and the floor of the mouth. This is the space where food is kept before it moves on to the esophagus. The orifice of the mouth is the line between the lower and upper lips and is...

Small Intestine
2013-03-04 15:13:09

The small intestine is the part of the digestive tract that follows the stomach and is followed by the large intestine. Formation and Orientation The small intestine is on average between 22 feet 6 inches and 24 feet 4 inches. It is composed of three distinct structural parts; the duodenum, the jejunum, and the ileum. The duodenum is the part of the intestine where most chemical breakdown happens; it is also the shortest part of the intestine. It starts at the duodenal bulb and stops...

Stomach
2013-03-04 14:34:35

The stomach is the hollow organ that helps along digestion after mastication (chewing). It is the next step after the esophagus and before the small intestines. Formation and Orientation The stomach is composed of four parts. The cardia is the first part of the stomach in the digestive tract. It is the part of the stomach that allows the food to empty from the esophagus. The most northern part of the stomach is the Fundus. This section is the part that creates the curved part of the...
