Physical activity enhances fecal lactobacilli in rats chronically drinking sweetened cola beverage.

Overweight and obesity have been linked with increased intake of sugar-sweetened beverages. On the other hand, physical activity has been known to lead to weight loss. Therefore, we hypothesized that exercise might influence the population in fecal microbiota as their changed abundance is often associated with shifts in the physical activity and diet.

Betalains in Edible Fruits of Three Cactaceae Taxa-, , and -Their LC-MS/MS and FTIR Identification and Biological Activities Evaluation.

, and plants belong to the Cactaceae family. They are mostly known as ornamental plants but also for their edible fruits, which can potentially be sources of betalains, such as betanin, a natural pigment used in the food industry, e.g.

Mucin pre-cultivated Lactobacillus reuteri E shows enhanced adhesion and increases mucin expression in HT-29 cells.

Adhesion of probiotic bacteria to the mucus layer lining the gastrointestinal tract is necessary for its effective colonisation and specific therapeutic effects. Enrichment of growth medium with mucin might stimulate bacterial adhesion, probably by increasing the expression of surface structures responsible for bacteria-gut epithelia and/or mucus interactions. The aim of this study was to determine if pre-cultivation of potentially probiotic strain Lactobacillus reuteri E (LRE) with mucin stimulates its adherence to colon cell line HT-29 and if the increased adhesion modulates mucin expression in these cells.

Inflammatory bowel disease: factors involved in pathogenesis.

The incidence of inflammatory bowel disease (IBD) in developed countries increases every year. The aetiology is still not completely understood and its clarification is a key prerequisite for effective prophylaxis and therapy. IBD is most-likely caused by a combination of several factors: environmental, genetic, immunological, and disruption of intestinal microbiota composition - dysbiosis.

[Gut microbiota: its development and relation to certain diseases].

Coexistence of humans with microorganisms is well known for a long time. Besides the association with infectious diseases, personal microbiota is important for human health, possibly for some non-infectious diseases. Colonization of the human body with appropriate microorganisms after delivery is essential for physiological immune system maturation and also has an influence on central nervous system development.
