Comparative Effects of Intragastric and Intraduodenal Administration of Quinine on the Plasma Glucose Response to a Mixed-Nutrient Drink in Healthy Men: Relations with Glucoregulatory Hormones and Gastric Emptying

Autor: Braden D Rose, Vida Bitarafan, Michael Horowitz, Peyman Rezaie, Christine Feinle-Bisset, Penelope C E Fitzgerald

Publikováno v: The Journal of Nutrition. 151:1453-1461

BACKGROUND In preclinical studies, bitter compounds, including quinine, stimulate secretion of glucoregulatory hormones [e.g., glucagon-like peptide-1 (GLP-1)] and slow gastric emptying, both key determinants of postprandial glycemia. A greater densi

Effects of intraduodenal administration of lauric acid and L-tryptophan, alone and combined, on gut hormones, pyloric pressures, and energy intake in healthy men

Autor: Sina S Ullrich, Christine Feinle-Bisset, Robert E. Steinert, Christina McVeay, Michael Horowitz, Penelope C E Fitzgerald

Publikováno v: The American Journal of Clinical Nutrition. 109:1335-1343

BACKGROUND The fatty acid, lauric acid ('C12'), and the amino acid, L-tryptophan ('Trp'), modulate gastrointestinal functions including gut hormones and pyloric pressures, which are important for the regulation of energy intake, and both potently sup

Suppression of Energy Intake by Intragastric l-Tryptophan in Lean and Obese Men: Relations with Appetite Perceptions and Circulating Cholecystokinin and Tryptophan

Autor: Sally D. Poppitt, Sina S Ullrich, Penelope C E Fitzgerald, Maryam Hajishafiee, Michael Horowitz, Kylie Lange, Christine Feinle-Bisset

BACKGROUND l-Tryptophan reduces energy intake in healthy men. The underlying mechanisms, including appetite, plasma cholecystokinin (CCK), tryptophan (Trp), and the ratio of Trp to large neutral amino acids (Trp:LNAAs ratio), and whether responses di

Intragastric administration of leucine and isoleucine does not reduce the glycaemic response to, or slow gastric emptying of, a carbohydrate-containing drink in type 2 diabetes

Autor: Sina S Ullrich, Michael Horowitz, Christine Feinle-Bisset, Kylie Lange, Rachel A. Elovaris, Maryam Hajishafiee, Penelope C E Fitzgerald

Publikováno v: Diabetes research and clinical practice. 171

In healthy individuals, intragastric administration of the branched-chain amino acids, leucine and isoleucine, diminishes the glycaemic response to a mixed-nutrient drink, apparently by stimulating insulin and slowing gastric emptying, respectively.

Effects of L-Phenylalanine on Energy Intake and Glycaemia-Impacts on Appetite Perceptions, Gastrointestinal Hormones and Gastric Emptying in Healthy Males

In humans, phenylalanine stimulates plasma cholecystokinin (CCK) and pyloric pressures, both of which are important in the regulation of energy intake and gastric emptying. Gastric emptying is a key determinant of postprandial blood glucose. We evalu

Effects of intraduodenal coadministration of lauric acid and leucine on gut motility, plasma cholecystokinin, and energy intake in healthy men

Autor: Sina S Ullrich, Christina McVeay, Robert E. Steinert, Michael Horowitz, Penelope C E Fitzgerald, Christine Feinle-Bisset

Publikováno v: American journal of physiology. Regulatory, integrative and comparative physiology. 318(4)

The fatty acid, lauric acid (C12), and the amino acid, leucine (Leu) stimulate gut hormones, including CCK, associated with suppression of energy intake. In our recent study, intraduodenal infusion of a combination of C12 and l-tryptophan, at loads t

Intragastric Lysine Lowers the Circulating Glucose and Insulin Responses to a Mixed-Nutrient Drink without Slowing Gastric Emptying in Healthy Adults

Autor: Robert E. Steinert, Christine Feinle-Bisset, Michael Horowitz, Iris Nkamba, Sina S Ullrich, Penelope C E Fitzgerald

Publikováno v: The Journal of Nutrition. 147:1275-1281

Background: Lysine is reported to lower the glycemic response to oral glucose in humans and, albeit at high loads, to slow gastric emptying of glucose and decrease food intake in rats.Objective: We investigated the effects of intragastrically adminis

Publikováno v: Journal of Neurogastroenterology and Motility

Background/Aims Nutrient-induced gut hormone release (eg, cholecystokinin [CCK]) and the modulation of gut motility (particularly pyloric stimulation) contribute to the regulation of acute energy intake. Non-caloric bitter compounds, including quinin
