Effects of ssp. SA-03 Supplementation on Reversing Phthalate-Induced Asthma in Mice.

Probiotics may protect against asthma. We want to investigate whether probiotics can reverse the adverse effects of phthalate exposure on asthma. We selected the female offspring of BALB/c mice, born from pregnant female mice fed with diethylhexyl phthalate (DEHP).

alleviate metabolic disorders via converting methionine to 5'-methylthioadenosine.

Dietary patterns and corresponding gut microbiota profiles are associated with various health conditions. A diet rich in polyphenols, primarily plant-based, has been shown to promote the growth of probiotic bacteria in the gastrointestinal tract, subsequently reducing the risk of metabolic disorders in the host. The beneficial effects of these bacteria are largely due to the specific metabolites they produce, such as short-chain fatty acids and membrane proteins.

Decolonization of carbapenem-resistant from the intestinal microbiota of model mice by phages targeting two surface structures.

Background: is a normal component of the human gastrointestinal tract microbiota. However, in some cases, it can cause disease. Over the past 20 years, the prevalence of antibiotic-resistant bacteria, such as carbapenem-resistant (CRKP), has been increasing.

Mining Gut Microbiota From Bariatric Surgery for MAFLD.

The progression of metabolic dysfunction associated fatty liver disease (MAFLD) leads to steatohepatitis, liver fibrosis and hepatocellular carcinoma. Thus far, there have been no FDA-approved medications for MAFLD. Bariatric surgery (BS) has been found to improve insulin resistance, steatohepatitis and liver fibrosis but is not recommended for treating MAFLD due to its invasiveness.

Housing condition-associated changes in gut microbiota further affect the host response to diet-induced nonalcoholic fatty liver.

Diet-induced obesity is the most widely used animal model for studying nonalcoholic fatty liver disease (NAFLD). However, the physiological effects of a high-fat diet (HFD) are inconsistent between different studies. To elucidate this mystery, mice raised with conventional (CONV), specific pathogen-free (SPF) and gentamicin (G) treatments and fed with standard diet (STD) or HFD were analyzed in terms of their physiology, gut microbiota composition, hepatic steatosis and inflammation.

Gnotobiotic mice inoculated with Firmicutes, but not Bacteroidetes, deteriorate nonalcoholic fatty liver disease severity by modulating hepatic lipid metabolism.

Nonalcoholic fatty liver disease (NAFLD) is a serious liver disorder and characterized by the hepatic accumulation of excess fatty acids. Clinical studies and animal models have shown a shift of gut microbiota from bacteroidetes to firmicutes in NAFLD patients and a diet-induced NAFLD mouse model. Therefore, we hypothesized that these 2 groups of bacteria may have differential effects on lipid metabolism in the liver, which further contributed to pathogenesis of NAFLD.

Supplementation with Beef Extract Improves Exercise Performance and Reduces Post-Exercise Fatigue Independent of Gut Microbiota.

Beef extract (BE) is a nutritional supplement obtained by cooking beef meat. Compared with traditional chicken essence or clam extract, BE is cheaper to produce and may be used for wound healing, as a chemotherapy supplement, or to prevent fatigue. In this study, we evaluated the potential beneficial effects of BE on exercise performance and the related role of the gut microbiota.

Effects of plant- and animal-based high-fat diets on lipid storage and distribution in environmental bacteria-colonized gnotobiotic mice.

Different edible oils such as lard and soybean oil have been reported to interact with the gut microbiota, affecting host lipid metabolism. However, whether bacteria derived from the environment influence host lipid metabolism remains unclear. This study aimed to clarify the roles of environmental bacteria in host lipid storage and distribution with various edible oils.
