Passing gas, especially very smelly gas, can be an embarrassing problem. Fortunately, home remedies such as diet and lifestyle changes can often prevent bad-smelling gas. In most cases, it is natural and healthy for a person to experience intestinal gas. It is not uncommon for farts to be either smelly or produce no odor at...
by Okayama University A recent study by Okayama University researchers found that short-chain fatty acids produced by intestinal bacteria trigger the extension of the dendrites of dendritic cells by inhibiting an enzyme known as histone deacetylase. This results in a stonger immune response. Credit: Dr. Kazuyuki Furuta from Okayama University, Japan Dendritic cells play a key...
by Niigata University Credit: Pixabay/CC0 Public Domain Researchers from Niigata University and Kyoto Prefectural University have revealed that small vesicles, around 100 nm in size, released by intestinal bacteria induce immune activation and progression of liver cirrhosis, as well as a reduction of serum albumin levels, subsequently leading to edema and ascites. The research is published in the...

Bray-Curtis distance was used as a distance metric. b An integrated topological map, tmap, showing how close genera, disease states, and clinical features are to...
The bacteria inside our guts are fine-tuning our metabolism, depending on our diet, and new research suggests how they accomplish it. Emory researchers have identified an obesity-promoting chemical produced by intestinal bacteria. The chemical, called delta-valerobetaine, suppresses the liver’s capacity to oxidize fatty acids. The findings were recently published in Nature Metabolism. Image credit: Emory University...

Thus, temocillin may be useful in treating severe urinary tract infections that give rise to fever,...
A high concentration of indolepropionic acid in the serum protects against type 2 diabetes, shows a new study from the University of Eastern Finland. Indolepropionic acid is a metabolite produced by intestinal bacteria, and its production is boosted by a fibre-rich diet. According to the researchers, the discovery provides additional insight into the role of...
