Oat β‐Glucan and Galactooligosaccharides Influence Gallstone Formation by Modulating the Gut Microbiota, Particularly Desulfovibrionales

iMetaMed, EarlyView.
Oat β‐glucan and galactooligosaccharides influence the formation of gallstones by modulating the gut microbiota, particularly the abundance of Desulfovibrionales. The primary mechanism involves metabolic byproducts associated with Desulfovibrionales inhibiting hepatic bile acid synthesis via both the hepatic FXR–SHP and intestinal FXR–FGF15 signaling ...

The minor bile acids of the toad, Bufo vulgaris formosus.

Journal of Lipid Research, 1983
Bile from the toad, Bufo vulgaris formosus, was found to contain a number of minor bile acids along with two major bile acids, 3 alpha, 7 alpha, 12 alpha-trihydroxy-5 beta-cholest-22-ene-24-carboxylic acid and 3 alpha, 7 alpha, 12 alpha-trihydroxy-5 beta-

Nano‐plastics disrupt systemic metabolism by remodeling the bile acid–microbiota axis and driving hepatic–intestinal dysfunction

iMeta, EarlyView.
The pervasiveness of microplastic pollution poses a growing health risk, yet its long‐term metabolic consequences remain poorly defined. Here, we exposed mice to polyethylene terephthalate nanoparticle (NP) and combined histopathology, biochemistry, metabolomics, and metagenomics to resolve their interactions.

Hepatic 3-hydroxy-3-methylglutaryl coenzyme A reductase activity and biliary lipid composition in man: relation to cholesterol gallstone disease and effects of cholic acid and chenodeoxycholic acid treatment

Journal of Lipid Research, 1981
The present work was undertaken in order to study whether or not there is a relation between hepatic HMG CoA reductase, hepatic cholesterol concentration, and biliary lipid composition.

Cholic Acid in Guinea Pig Bile.

Experimental Biology and Medicine, 1960
SummaryCholic (3α, 7α, 12α-trihydroxycholanic) acid has been isolated from the guinea pig bile obtained from gall bladders as well as by biliary fistulae. However, this bile acid was found only in the bile of adult and not of immature guinea pigs. The other 2 bile acids isolated, chenodeoxycholic (3α, 7α-dihydroxycholanic) and 7-ketolithocholic (3α ...

Advancing Single‐Walled Carbon Nanotubes toward Next‐Generation Electronic Materials: The Critical Roles of Purity and Processability

Small Methods, EarlyView.
Single‐walled carbon nanotubes (SWNTs) are promising for a wide range of applications. In particular, their exceptional electrical conductivity positions them as potential alternatives to traditional metal conductors. This review identifies the key mechanisms governing their conductivity within composites and proposes practical pathways for translating

Bile acids in the rat: studies in experimental occlusion of the bile duct

Journal of Lipid Research, 1966
Bile acids in the plasma, urine, and small intestine of adult male rats with occluded bile ducts have been studied using a method of high specificity for their determination. After bile duct ligation cholic acid rapidly accumulates in the plasma for 8 hr,

Microbiological Dehydroxylation of Cholic Acid [PDF]

Nature, 1963
THE transformation of steroids by micro-organisms has been extensively applied to the steroid hormones and their derivatives1. More recently this technique has been extended to other compounds2. However, the dehydroxylation reaction of steroids by micro-organisms has not been reported.

Advances in cholesterol and lipoproteins detection for healthcare: A review

VIEW, EarlyView.
Cholesterol is one of the main biomarkers related to the development of cardiovascular diseases. Its detection still relies on traditional methods of analysis, such as gas and liquid chromatographies. Detection of free cholesterol in saliva with redox or enzymatic sensors or detection of lipoproteins in blood with aptamer sensors are currently the most

Relationship Between Fecal Bile Acid Profile and Intestinal Microbiota in Patients With Chronic Radiation Enteritis

Journal of Digestive Diseases, EarlyView.
Patients with chronic radiation enteritis (CRE) demonstrate dysregulated bile acid (BA) metabolism, characterized by an increased proportion of primary BAs and a decreased proportion of secondary BAs. Moreover, the diversity of the intestinal microbiota is significantly reduced in individuals with CRE, and there is a bidirectional interaction between ...
