Diabetes melitus merupakan masalah kesehatan global dengan tingginya angka kematian akibat berbagai komplikasi yang ditimbulkannya dan diabetes tipe 2 menjadi penyebab utama seiring bertambahnya penderita obesitas. Pengembangan obat-obat anti dilakukan, untuk menemukan kandidat obat baru tidak hanya menurunkan kadar glukosa darah tetapi diharapkan memiliki efek lebih, seperti mampu merestorasi ...

A rodent model of controlled acute hyperglycemia that is sensitive to glucose-lowering agents insulin and glucagon-like peptide-1 (GLP-1) analog has been developed. The studies show that anesthesia could be induced in fasted rats with ketamine (100 mg/kg) plus a low dose of xylazine (5 mg/kg) without inducing the acute hyperglycemia typically associated with these agents. Under these conditions...

Although the α-glucosidase inhibitor miglitol (MG) has been reported to have anorexigenic effects, the mechanism remains to be elucidated. The objective of this study was to explore the effects of MG on appetite in relation to concomitant changes in postprandial gut hormone levels. This randomized open-label crossover study included 20 healthy volunteers. The effects of 50 mg MG on glucagon-lik...

The present special issue was aimed at elucidating the role and the effects of glucagon-like peptide-1 (GLP-1) in type 2 diabetes. GLP-1 is a gastrointestinal hormone, mainly secreted after meals, capable of increasing glucose-stimulated insulin release and inhibits food intake. The physiological activity of this hormone has been demonstrated to be impaired in obese subjects and in patients wit...

Context: The combination of peptide YY (PYY) and glucagon-like peptide-1 (GLP-1) has been proposed as a potential treatment for diabetes and obesity. However, the combined effects of these hormones, PYY3–36 and GLP-17–36 amide,on glucose homeostasis are unknown. Objective: To investigate the acute effects of PYY3–36 and GLP-17–36 amide, individually and in combination, on insulin secretion and ...

The gastrointestinal (GI) tract senses the ingestion of food and responds by signaling to the brain to promote satiation and satiety. Representing an important part of the gut-brain axis, enteroendocrine L-cells secrete the anorectic peptide hormones glucagon-like peptide-1 (GLP-1) and peptide YY (PYY) in response to the ingestion of food. The release of GLP-1 has multiple effects, including th...

OBJECTIVE The prevalence of obesity and related co-morbidities is reaching pandemic proportions. Today, the most effective obesity treatments are glucagon-like peptide 1 (GLP-1) analogs and bariatric surgery. Interestingly, both intervention paradigms have been associated with adaptive growth responses in the gut; however, intestinotrophic mechanisms associated with or secondary to medical or s...
