Appetite linked to healthier gut bacteria in over-60s
by King’s College London Credit: Unsplash/CC0 Public Domain Over-60s with a good appetite have more diverse and different communities of microbes in their gut than those with a poor appetite, a study has found. The study, published today in the Journal of Cachexia, Sarcopenia and Muscle from King’s College London and the University of Southampton, is the first...
Study finds changes in gut microbiome connected to Alzheimer’s-like behavior
by Oregon Health & Science University Credit: CC0 Public Domain New research in mice published today in the journal Scientific Reports strengthens the growing scientific consensus regarding the role of the gut microbiome in neurodegenerative disorders including Alzheimer’s disease. The study, led by researchers at Oregon Health & Science University, found a correlation between the composition of the gut...
Exposure to superbacteria among visitors to the tropics more extensive than previously thought
by University of Helsinki Credit: Unsplash/CC0 Public Domain Exploring exposure to superbacteria, researchers at the University of Helsinki and Helsinki University Hospital got unexpected results from an international collaborative study conducted in real time among 20 travelers to Southeast Asia. All the participants were found to contract superbacteria within a week after arriving in the destination. A detailed...

Study identifies ‘Achilles heel’ of bacteria linked to Crohn’s disease
WEILL CORNELL MEDICINE The discovery of an “Achilles heel” in a type of gut bacteria that causes intestinal inflammation in patients with Crohn’s disease may lead to more targeted therapies for the difficult to treat disease, according to Weill Cornell Medicine and NewYork-Presbyterian investigators. In a study published Feb. 3 in Cell Host and Microbe, the...

Bile acids may play previously unknown role in Parkinson’s
VAN ANDEL RESEARCH INSTITUTE GRAND RAPIDS, Mich. (Feb. 2, 2021) — What does bile acid production in the digestive tract have to do with Parkinson’s disease? Quite a lot, according to a sweeping new analysis published in the journal Metabolites. The findings reveal that changes in the gut microbiome — the rich population of helpful microbes that call the...
‘Organs-on-a-chip’ system sheds light on how bacteria in the human digestive tract may influence neurological diseases
by Massachusetts Institute of Technology MIT researchers have developed an “organs-on-a-chip” system that replicates interactions between the brain, liver, and colon. Credit: Martin Trapecar, MIT In many ways, our brain and our digestive tract are deeply connected. Feeling nervous may lead to physical pain in the stomach, while hunger signals from the gut make us feel irritable. Recent...
