Background & Objectives: Lifestyle modification through healthy diets and sufficient physical activity plays a pivotal role in the improvement of overall health. This study aimed to evaluate the effects of a single session of concurrent exercise on the plasma levels of peptide YY (PYY) and neuropeptide Y (NPY) in obese young men. Material and Methods: In total, 24 obese young men with mean a...
Intraveneous (i.v.) PYY(3-36) infusions have been reported to reduce energy intake (EI) in humans, whereas few studies exist on effects of PYY(1-36). The aim of the present study was to examine effects of subcutaneous (sc) injections of PYY(1-36) and PYY(3-36) on appetite, ad libitum EI, plasma concentrations of PYY and free fatty acids (FFA) in obese males. Twenty-four males (BMI 27-40 kg/m(2)...
Peptide YY (PYY) is secreted postprandially from the endocrine L cells of the gastrointestinal tract. PYY(3-36), the major circulating form of the peptide, is thought to reduce food intake in humans and rodents via high-affinity binding to the autoinhibitory neuropeptide Y (NPY) receptor within the arcuate nucleus. We studied the effect of early light-phase injection of PYY(3-36) on food intake...
BACKGROUND Recent findings suggest that low plasma peptide YY (PYY) levels may contribute to diet-induced human obesity and justify PYY replacement therapy. Although the pharmacological value of PYY is controversial, further study of the secretion of the precursor PYY(1-36) and the pharmacologically active PYY(3-36) is indicated to determine the potential role in energy balance regulation. AI...
Glucagon-like peptide-1 (GLP-1), peptide YY (3-36) [PYY(3-36)], amylin, ghrelin, insulin, and leptin are thought to act as hormonal signals from periphery to brain to control food intake. Here, we determined the effects of solid-phase extraction of plasma in measuring these hormones in blood of lean and diet-induced obese rats. Individual enzyme-linked immunoassays and a multiplex assay were us...
abstract the third millennium has started, but the world is facing with serious challenges in achieving international security and peace. various human rights violations have lead the states to find means to protect human rights. also article 55 of the united nations charter introduces the respect to human rights and fundamental freedom as the most suitable ways to realize peace and security. ...
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
Increased dietary fiber (DF) fermentation and short-chain fatty acid (SCFA) production may stimulate peptide tyrosine-tyrosine (PYY) secretion. In this study, the effects of hindgut SCFA production on postprandial PYY plasma levels were assessed using different experimental diets in a porto-arterial catheterized pig model. The pigs were fed experimental diets varying in source and levels of DF ...
Peptide YY (3-36) [PYY (3-36)] is postulated to act as a hormonal signal from the gut to the brain to inhibit food intake and gastric emptying. A mixed-nutrient meal produces a prolonged 2-3 h increase in plasma levels of both PYY (3-36) and PYY (1-36). We determined the dose-dependent effects of 3-h iv infusions of PYY (3-36) and PYY (1-36) (0.5-50 pmol.kg(-1).min(-1)) at dark onset on food in...
abstract: postmethod is a newly developed pedagogy which as an alternative to method rejects the notion of good or bad methods and the concept of best method that can be generalized and appropriate for all contexts. instead, it treats each context as unique and one of a kind which cant be compared with other cases. this study is a postmethod-oriented one which investigates whether and how far t...
