چکیده سابقه و هدف. انتخاب مناسب تمرین بدنی و ملاحظات تغذیه ای، عاملی مهم در تغییر شیوه زندگی نوجوانان چاق و شاخصی موثر در کنترل و درمان چاقی محسوب می شود. هدف ما تعیین اثر هشت هفته تمرینHIT در شرایط ایزوانرژیک و مصرف آرژنین بر سیگنال PYY3-36 و شاخص های آنتروپومتریک پسران چاق بود. مواد و روش ها. در شرایط ایزوانرژیک 20 نوجوان چاق به صورت تصادفی به دو گروه 1) تمرینHIT و دارونما (10 نفر) و 2) تم...
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 ...
BACKGROUND Peripheral infusion of glucagon-like peptide 1 (GLP-1) or peptide YY 3-36 (PYY3-36) reduces food intake in healthy, obese, and diabetic subjects. In vivo, both peptides are cosecreted from intestinal L cells; GLP-1 is subject to rapid breakdown by dipeptidyl peptidase IV, and together with PYY3-36 it is likely to be degraded in the liver before entering the systemic circulation. The ...
The intestinal hormones CCK and PYY3-36 inhibit gastric emptying and food intake via vagal afferent neurons. Here we report that CCK regulates the expression of Y2R, at which PYY3-36 acts. In nodose ganglia from rats fasted up to 48 h, there was a fivefold decrease of Y2R mRNA compared with rats fed ad libitum; Y2R mRNA in fasted rats was increased by administration of CCK, and by refeeding thr...
To examine the effect on serum lipase activity and protein concentration of intravenous infusions of glucagon-like peptide-1 (GLP-1) and peptide YY (PYY3-36) and of an ad libitum meal in healthy overweight men. Twenty-five healthy, male subjects participated in this randomized, double-blinded, placebo-controlled 4-arm crossover study (Body Mass Index (BMI): 29 ± 3 kg/m2, age: 33 ± 9 years). On ...
1454 longer to eat their first meal than controls did and then, for the next 6 hours, ate less at each meal. As the team reported in September in the American Journal of Physiology, monkeys receiving the peptide also held food in their stomachs longer than controls did, which may explain, in part, why subsequent appetite diminished. Still, Tschoëp and Moran point out, and Bloom concedes, no stu...
Laparoscopic Roux-en-Y gastric bypass (LRYGBP) reduces appetite and induces significant and sustainable weight loss. Circulating gut hormones changes engendered by LRYGBP are implicated in mediating these beneficial effects. Laparoscopic sleeve gastrectomy (LSG) is advocated as an alternative to LRYGBP, with comparable short-term weight loss and metabolic outcomes. LRYGBP and LSG are anatomical...
Extracts of human term amniotic, placental, and chorion/decidua tissue contained, respectively, 4.36 +/- 2.79 (pmol/g wet wt; mean +/- S.E.M.: n = 5). 2.78 +/- 0.5 (n = 5) and 0.68 +/- 0.68 (n = 5) peptide YY (PYY)-like immunoreactivity. Using a specific PYY antiserum, gel filtration chromatography and reverse-phase high performance liquid chromatography (HLPC), amniotic, placental and fetal in...
The neuropeptide Y (NPY)/peptide YY (PYY) system has been implicated in the physiology of obesity for several decades. More recently ignited enormous interest in PYY3-36, an endogenous Y2-receptor agonist, as a promising anti-obesity compound. Despite this interest, there have been remarkably few subsequent reports reproducing or extending the initial findings, while at the same time studies fi...
The purpose of the present study was to investigate appetite-related hormonal responses and energy intake after a 20 km run in trained long distance runners. Twenty-three male long-distance runners completed two trials: either an exercise trial consisting of a 20 km outdoor run (EX) or a control trial with an identical period of rest (CON). Blood samples were collected to determine plasma acyla...
