TLDR
The focus then shifts to selected aspects of hormonal regulation of carbohydrate metabolism and dietary carbohydrates and their variable effects on glycogen and glucose turnover, and the correlation of dietary carbohydrates with fish health.Abstract:
The utilisation of dietary carbohydrates and their effects on fish metabolism are reviewed. Details on how dietary carbohydrates affect growth, feed utilisation and deposition of nutrients are discussed. Variations in plasma glucose concentrations emphasizing results from glucose tolerance tests, and the impact of adaptation diets are interpreted in the context of secondary carbohydrate metabolism. Our focus then shifts to selected aspects of hormonal regulation of carbohydrate metabolism and dietary carbohydrates and their variable effects on glycogen and glucose turnover. We analyse the interaction of carbohydrates with other nutrients, especially protein and protein sparing, and de novo synthesis of lipids, and finish by discussing the correlation of dietary carbohydrates with fish health.read more

Nutritional evaluation of rendered animal by products and blends as suitable partial alternatives for fishmeal in diets for rainbow trout (Oncorhynchus mykiss)
TL;DR: The potential of replacing high quality fishmeal with terrestrial animal by-products on a digestible protein and energy basis was established using preliminary digestibility trials, followed by a comprehensive 12-week nutrition trial with sub-adult class rainbow trout.

TL;DR: In this paper, the effects of temperature variation on the metabolism of Astyanax lacustris, a species of freshwater fish common in the subtropical region of Brazil, were investigated.

Environmental risk assessment for excipients from galenical pharmaceutical production in wastewater and receiving water
TL;DR: In this article, a predicted environmental concentration (PEC) was calculated for the wastewater treatment plants (WWTPs) and the receiving water, the River Rhine for both sites, based on maximum daily losses of the single excipients to wastewater, derived by mass balance, and the site-specific dilution factor.

TL;DR: Dietary biotin significantly decreased plasma glucose by increasing insulin level in plasma, activating PI3K (phosphoinositide 3-kinase)/AKT (protein kinase b) signaling pathway, promoting glucose transportation, glycolysis, pentose phosphate pathway and glycogen synthesis but inhibiting gluconeogenic pathway.

Cortisol in teleosts: dynamics, mechanisms of action, and metabolic regulation
TL;DR: This review attempts to delineate common themes on the physiological and metabolic roles of cortisol in teleost fishes and to suggest new approaches that might overcome some of the inconsistencies on the role of this multifaceted hormone.

Stress responses and disease resistance in salmonid fish: Effects of chronic elevation of plasma cortisol
TL;DR: It is shown, by means of intraperitoneal implantation of cortisol, that chronic elevation of plasma cortisol levels in the brown trout results in a dose-dependent increase in mortality due to common bacterial and fungal diseases.

What if Minkowski had been ageusic? An alternative angle on diabetes.
TL;DR: It is suggested that the phenomena of insulin resistance and hyperglycemia might be more readily understood if viewed in the context of underlying abnormalities of lipid metabolism.

Pancreatic beta-cells are rendered glucose-competent by the insulinotropic hormone glucagon-like peptide-1(7-37)
TL;DR: It is reported here that GLP-1 confers glucose sensitivity to glucose-resistant p-cells, a phenomenon the authors term glucose competence, which is similar to membrane depolarization, the generation of action potentials, and Ca2+ influx, events that are known to trigger insulin secretion.

Glucose-6-phosphate dehydrogenase: a "housekeeping" enzyme subject to tissue-specific regulation by hormones, nutrients, and oxidant stress.
TL;DR: The central question of this review is “How can the G6PDH gene be constitutively expressed in some tissues while displaying adaptive regulation in others when there exists a single transcription unit for the gene?”
