Indole is produced from dietary tryptophan by tryptophanase in intestinal bacteria, such as Escherichia coli. In the liver, indole is converted into indoxyl sulfate, a uremic toxin and risk factor for chronic kidney disease (CKD). Probiotics and prebiotics are currently

Electrophoresis, 16(8), 1510-1518 (1995-08-01)
Enantiomers can be separated by using human serum transferrin as a chiral phase. With the help of the native protein we were able to separate enantiomers with high efficiency, using a low ionic strength 2-(N-morpholino)ethanesulfonic acid (MES) buffer, pH 6

The effect of partial cystectomy on the occurrence of pre-neoplastic lesions, papillary or nodular hyperplasia (PN hyperplasia), of the bladder in male F344 rats was studied in an experiment in which bladder carcinogens and promoters were given to the rats
A J Jonas et al.

Tryptophan ethyl ester, a lipid-soluble tryptophan derivative, was used to bypass defective gastrointestinal neutral amino acid transport in a child with Hartnup disease. The child's baseline tryptophan concentrations in serum (20 +/- 6 microM) and cerebrospinal fluid (1.0 +/- 0.2
R P Kwok et al.
Neuroendocrinology, 45(4), 267-273 (1987-04-01)
In this study we investigated the effect of insulin on striatal 5-hydroxytryptamine and tryptamine in streptozotocin-diabetic and in normal rats. Streptozotocin-diabetic rats show a reduction in rat striatal tryptophan, 5-hydroxytryptamine, and 5-hydroxyindole acetic acid, an effect observed at 7 or
