Tryptophan derivatives as non‐invasive diagnostic indicators for obesity‐related MASLD in children and adolescents

open access: yesDiabetes, Obesity and Metabolism, Volume 27, Issue 12, Page 7544-7560, December 2025.
Abstract Aims Metabolic dysfunction‐associated steatotic liver disease (MASLD) represents a major health burden in children and adolescents with obesity. This study aimed to characterize metabolic alterations associated with obesity‐related MASLD and to evaluate the potential of tryptophan (TRP)‐derived metabolites as non‐invasive biomarkers for early ...

The role of social rank in the development, physiology and reproductive strategies in salmonids [PDF]

open access: yes, 2013
Salmonids naturally organise into social hierarchies both in the wild and aquaculture. This thesis investigates how social rank influences the physiology and development of salmonids with different life strategies using Atlantic salmon (Salmo salar) as a

Excretion of Urinary 5-HIAA in Dog Pellagra.

open access: yesExperimental Biology and Medicine, 1962
SummaryDogs kept on a diet deficient in tryptophan and nicotinic acid, developed typical pellagra, but their 5-HIAA urinary excretion did not differ from that of control dogs. The reasons for this discrepancy lie mainly i the typical course of canine pellagra which invariably results in early death due to intestinal or buccal infection (black tongue ...
