Are Strong Bronsted Acids Necessarily Strong Lewis Acids? [PDF]
arXiv, 2006 The Broensted and Lowry acid base theory is based on the capacity of proton donation or acceptance (in the presence or absence of a solvent) whereas the Lewis acid base theory is based on the propensity of electron pair acceptance or donation. We explore through DFT calculation the obvious question whether these two theories are in conformity with each

Isolation of 10 cyclosporine metabolites from human bile [PDF]
, 1989 Ten metabolites of cyclosporine were isolated from the ethyl ether extract of bile from four liver transplant patients receiving cyclosporine. Two of the metabolites were unique and previously unidentified.

The Role of the Gut Microbiota in Bile Acid Metabolism.
Annals of Hepatology, 2017 The gut microbiota has been considered a cornerstone of maintaining the health status of its human host because it not only facilitates harvesting of nutrients and energy from ingested food, but also produces numerous metabolites that can regulate host ...

The Factors of the Classification of Protein Amino Acids [PDF]
This paper is published in GLASNIK of Montenegrin Academy of
Science and arts, 2000, 13, pp. 173-194, 2006 In this work it is shown that three pairs of the factors appear to be the key, i.e. main factors of a natural classification of protein (canonical) amino acids within the amino acid (genetic) code. First pair: the factors of the habit of an amino acid molecule (size and polarity).

The Korean Journal of GastroenterologyDiarrhea is a very common gastrointestinal symptom, and the presence of higher concentrations of bile acid in the colon leads to bile acid diarrhea (BAD). In BAD patients, a portion of bile from the small intestine that is normally controlled by enterohepatic circulation is present at a high concentration in the lumen of the large intestine, resulting ...

Bile Acid Sulfation: A Pathway of Bile Acid Elimination and Detoxification [PDF]
Toxicological Sciences, 2009 Sulfotransferase-2A1 catalyzes the formation of bile acid-sulfates (BA-sulfates). Sulfation of BAs increases their solubility, decreases their intestinal absorption, and enhances their fecal and urinary excretion. BA-sulfates are also less toxic than their unsulfated counterparts.

Advanced Science, EarlyView.TRIM25‐mediated ubiquitination of INSIG1 serves as a key driver of lipid metabolism dysregulation in MASH progression. It identifies a novel small‐molecule inhibitor, C27H26N2O4S, which effectively inhibits TRIM25 activity, reducing lipid accumulation and inflammation.

Examination of bile acid negative feedback regulation in rats.
Journal of Lipid Research, 1988 Recent data obtained using cultured rat hepatocytes showed that bile acids do not inhibit bile acid synthesis, whereas cholesterol concentrations vary in parallel with bile acid synthesis (Davis et al. (1983. J. Biol. Chem. 258: 4079-4082).

A Hollow Shell‐Lattice Soft Robot in Flexible Pipelines with Flowing Fluids
Advanced Science, EarlyView.This study proposes a novel shell‐lattice robot with hollow bodies, capable of crawling through pipes with flowing fluids of high velocities and viscosities and mixed with impurities. The robot also features capabilities of crawling with high payloads, in curved pipes, and unthethered crawling. These unique properties make this robot high promising for
