1. A grelina, mas não PYY(3-36), está associada com a resistência à insulina independente do peso corporal em ratos Wistar
Objetivo: O objetivo deste estudo foi avaliar a associação entre a resistência à insulina e os níveis de grelina e PYY em jejum em ratos Wistar. Materiais e métodos: Um total de 25 ratos Wistar machos, pesando 200-300 g, foi usado neste estudo. Os animais foram mantidos em gaiolas com um ciclo de luz escuro de 12/12h e alimentados com ração padrã

2. Avaliação das incretinas GLP-1 e PYY em pacientes com Diabetes Mellitus 2 submetidos a Duodenal Swicth Parcial / Evaluation of the incretin GLP-1 and PYY in patiens with Diabetes Mellitus 2 undergoing Partial Duodenal Swicth
Diabetes mellitus do tipo 2 (DM2), assim como a Síndrome Metabólica (SM), é uma desordem metabólica e multifatorial que atualmente se apresenta como pandemia mundial com reflexos na morbimortalidade, possivelmente em decorrência do descompasso entre a evolução biológica e cultural do homem. Foi objeto de investigação do presente estudo analisar a e

3. Correlations of circulating peptide YY and ghrelin with body weight, rate of weight gain, and time required to achieve the recommended daily intake in preterm infants
The objective was to elucidate the relationships between serum concentrations of the gut hormone peptide YY (PYY) and ghrelin and growth development in infants for potential application to the clinical observation index. Serum concentrations of PYY and ghrelin were measured using radioimmunoassay from samples collected at the clinic. For each patient, gestat

4. Hormônios reguladores do apetite em mulheres obesas com e sem compulsão alimentar
OBJETIVO: O objetivo deste estudo foi avaliar, antes e após a refeição, as concentrações séricas de hormônios ligados ao controle do apetite (peptídeo YY3-36, grelina total, leptina e insulina) em mulheres obesas com e sem episódios de compulsão alimentar e compará-las às mulheres de peso normal. MÉTODOS: Vinte e cinco mulheres com idade entre 3

5. The effect of neuropeptide Y and peptide YY on electrogenic ion transport in rat intestinal epithelia.
1. Neuropeptide Y (NPY), peptide YY (PYY) and, to a lesser extent, human pancreatic polypeptide (HPP) reduced short-circuit current (SCC) in a concentration-dependent manner in epithelial preparations of rat jejunum and descending colon. 2. From concentration-response curves in the jejunum EC50 values of 3 nM for PYY and 10 nM for NPY were obtained. HPP was

6. Mice lacking pro-opiomelanocortin are sensitive to high-fat feeding but respond normally to the acute anorectic effects of peptide-YY3-36
Inactivating mutations of the pro-opiomelanocortin (POMC) gene in both mice and humans leads to hyperphagia and obesity. To further examine the mechanisms whereby POMC-deficiency leads to disordered energy homeostasis, we have generated mice lacking all POMC-derived peptides. Consistent with a previously reported model, Pomc-/- mice were obese and hyperphagi

7. The glucose-dependent insulinotropic polypeptide and glucose-stimulated insulin response to exercise training and diet in obesity
Aging and obesity are characterized by decreased β-cell sensitivity and defects in the potentiation of nutrient-stimulated insulin secretion by GIP. Exercise and diet are known to improve glucose metabolism and the pancreatic insulin response to glucose, and this effect may be mediated through the incretin effect of GIP. The purpose of this study was to ass

8. The RAPID Method for Blood Processing Yields New Insight in Plasma Concentrations and Molecular Forms of Circulating Gut Peptides
The correct identification of circulating molecular forms and measurement of peptide levels in blood entails that the endocrine peptide being studied is stable and recovered in good yields during blood processing. However, it is not clear whether this is achieved in studies using standard blood processing. Therefore, we compared peptide concentration and for

9. Marked decrease of neuropeptide Y Y2 receptor binding sites in the hippocampus in murine prion disease
Using autoradiographic binding methodology with monoiodinated peptide YY together with the agonists neuropeptide Y (NPY) and NPY (13–36), as well as in situ hybridization with oligonucleotide probes complementary to the NPY Y2 receptor (Y2-R) mRNA, we have studied whether or not intracerebral prion inoculation affects Y2-Rs in male CD-1 mice. Monoiodinated
