Heat shock proteins (HSP) 25 and 72 are expressed normally by surface colonocytes but not by small intestinal enterocytes. We hypothesized that luminal commensal microflora maintain the observed colonocyte HSP expression. The ability of the small intestine to respond to bacteria and their products and modulate HSPs has not been determined. The effects of luminal bacterial flora in surgically cr...

The concept of probiotics has been around for about 100 years. Yet its impact on human nutrition is still an emerging concept. Lack of convincing scientific validation for the efficacy of any ingested probiotic bacterium on intestinal health, has been a major reason for the low impact of probiotics on human nutrition. Obtaining positive scientific validation requires the use of suitable probiot...

Icariin is a major bioactive compound of Epimedii Herba, a traditional oriental medicine exhibiting anti-cancer, anti-inflammatory and anti-osteoporosis activities. Recently, the estrogenic activities of icariin drew significant attention, but the published scientific data seemed not to be so consistent. To provide fundamental information for the study of the icaritin metabolism, the biotransfo...

Red cabbage is, among different vegetables, one of the major sources of anthocyanins. In the present study an in vitro digestion method has been used to assay the influence of the physiological conditions in the stomach and small intestine, as well as faecal microflora on anthocyanins stability in red cabbage and anthocyanin-rich extract. The recovery of anthocyanins during in vitro gastrointes...

This review describes our knowledge of biotin transport in the small intestine of humans and other mammals and presents recent findings in the area. Previous studies have shown that biotin transport across the brush border membrane of the small intestinal absorptive cells occurs via a carrier-mediated, Na gradientdependent, electroneutral mechanism. Exit of biotin out of the enterocyte, i.e., t...

The objective of the present study was to demonstrate the effect of dietary resistant dextrins, as potential prebiotics, on the intestinal microflora of young rats. Enzyme-resistant dextrin, prepared by heating of potato starch in the presence of hydrochloric (0.1% dsb) and tartaric (40% dsb) acid at 130ºC for 2 h (CA-dextrin). The experiment was performed on 24 Wistar male rats at 3-wk of age,...

The study was conducted to investigate the effects of different levels of xylanase on performance, blood parameters, intestinal morphology, microflora and digestive enzyme activities of broilers. The wheat-based diets were supplemented with 0, 500, 1,000, 5,000 U/kg xylanase. Xylanase supplementation significantly (p<0.05) improved the feed:gain ratio of broilers from 1 to 21 d and 1 to 42 d. S...

The effect of an intestinal microflora consisting of selected microbial species on myoelectric activity of small intestine was studied using germ-free rat models, with recording before and after specific intestinal colonization, in the unanesthetized state. Intestinal transit, neuropeptides in blood (RIA), and neuromessengers in the intestinal wall were determined. Clostridium tabificum vp 04 p...

Nile tilapia ( Oreochromis niloticus ) is one of the most important commercial freshwater fish in China, and dietary transition occurs their different life stages. The gut microbiota to host health. relationships among diet, microbiota, development are not well known. In present study, we attempted understand how diet associated with community dynamics during tilapia. first experiment was perfo...

: This paper aims to analyze how intestinal flora regulates liver fibrosis pathogenesis and evaluate the regulatory effect of traditional Chinese medicine (TCM) on flora, providing new insights into treatment. Destruction microbiome can lead development, accelerating microbiome’s disruption. TCM effectively regulate helping prevent treat fibrosis. review discusses mechanisms behind changes in t...
