Six-Week Endurance Exercise Alters Gut Metagenome That Is not Reflected in Systemic Metabolism in Over-weight Women. Frontiers in Microbiology, 2018; 9 DOI: 10.3389/fmicb.2018.02323

According to recent research, endurance exercise training beneficially modifies gut microbiota composition. After six weeks of training, potentially inflammation causing microbes (Proteobacteria) decreased and microbes that are linked to enhanced metabolism (Akkermansia) increased. Even though there was no significant drop in the weight of the subjects, exercise had other beneficial health effects, says Academy of Finland research fellow Satu Pekkala from the Faculty of Sport and Health Sciences of the University of Jyväskylä.

“We found that phospholipids and cholesterol in VLDL particles decreased in respons...

Normal and cancerous pancreatic tissue. The blue background represents the cells that produce digestive juices supplied by the pancreas to the gut, and the red dots—seen only in the cancerous pancreas—represent the bacteria found to be a thousand times more abundant than normal.

Antibiotics may make immunotherapy more effective against pancreatic cancer. The population of bacteria in the pancreas increases more than a thousand fold in patients with pancreatic cancer, and becomes dominated by species that prevent the immune system from attacking tumor cells. These are the findings of a study conducted in mice and in patients with pancreatic ductal adenocarcinoma (PDA), a form of cancer that is usually fatal within two years...
