AIMS To investigate the anorectic effect of L-arginine (L-Arg) in rodents. METHODS We investigated the effects of L-Arg on food intake, and the role of the anorectic gut hormones glucagon-like peptide-1 (GLP-1) and peptide YY (PYY), the G-protein-coupled receptor family C group 6 member A (GPRC6A) and the vagus nerve in mediating these effects in rodents. RESULTS Oral gavage of L-Arg reduce...
Peptide YY(3-36) (PYY(3-36)) is released by endocrine cells of the gut and may serve as an important long-distance neuropeptide signal relating energy balance information to the brain to depress food intake. The postulated mechanism is the activation of anorexigenic proopiomelanocortin (POMC) neurons of the hypothalamic arcuate nucleus. In striking contrast, using voltage and current-clamp reco...
Adrenergic activation of electrogenic K+ secretion in isolated mucosa from guinea pig distal colon was desensitized by peptide-YY (PYY). Addition of PYY or neuropeptide-Y (NPY) to the bathing solution of mucosae in Ussing chambers suppressed the short-circuit current (Isc) corresponding to electrogenic Cl- secretion, whether stimulated by epinephrine (epi), prostaglandin-E2 (PGE2), or carbachol...
In animals, colonic infusion of SCFA does not affect glucagon-like peptide-1 (GLP-1) release whereas intravenous infusion does and SCFA may directly stimulate peptide YY (PYY) release. It is unknown whether SCFA and their route of administration affect human blood concentrations of GLP-1 and PYY. Our aim was to conduct a pilot study to determine the effects of intravenous and rectal acetate on ...

Ghrelin stimulates, while glucagon-like peptide-1 (GLP-1) and peptide YY(3-36) [PYY(3-36)] inhibit, food intake and gastric emptying in rats. We determined the dose-dependent effects of a 3-h intravenous infusion of ghrelin at dark onset on food intake in freely feeding rats, and on the inhibitory effects of intravenous infusion of GLP-1 and PYY(3-36) on food intake and gastric emptying. Ghreli...
Antisera raised against porcine neuropeptide Y (NPY) and peptide YY (PYY) were characterized with regard to immunohistochemical staining, cross-reactivity to several pancreatic polypeptide (PP)-related peptides, and radioimmunoassayable tissue levels in the rat and pig. The NPY antiserum (102B) reacted with nerves in many areas of both the central and peripheral nervous systems, but it did not ...
Strumal carcinoid tumor of the ovary is a rare subtype of ovarian carcinoid tumors; it is characterized by an intimate mixture of thyroid and carcinoid tissues. We present a case of a 64-year-old woman who presented with the chief complaint of persistent, severe constipation for over 5 years; she was later found to have an ovarian strumal carcinoid tumor. Computed tomography showed a well-defin...
Abstract Introduction Time-restricted eating (TRE) is a dietary strategy in which energy consumed over 6-10h window during the day and associated with reduced intake subsequent weight loss people obesity. However, impact of isocaloric TRE on obesogenic factors such as hormones related to hunger appetite, well expenditure metabolic rate relatively unknown. We therefore investigated 1 week obesit...
هدف از مطالعه حاضر بررسی تاثیر هشت هفته تمرین تناوبی شدید همراه با مکملیاری آلژینات سدیم بر سطح PYY و نیمرخ لیپیدی در مردان مبتلا به سندرم متابولیک بود. در تحقیق حاضر که یک پژوهش نیمهتجربی بود، 24 مرد جوان مبتلا به سندرم متابولیک به صورت تصادفی در 3 گروه، تمرین تناوبی شدید با مکمل (8n=)، تمرین تناوبی شدید با دارونما (8n=) و کنترل(8n=) قرار گرفتند. برنامه تمرینی، با شدت 85 تا 95 ضربان قلب ذخیر...
