This study aims to determine the effect of a single exhausting exercise on plasma PYY, NPY and IGF-1 in young athletes. Thirty-one young athletes (aged 19.52±2.75 years, body mass 79.24±16.13 kg, height 173±6.49 cm, and body fat 16.37±5.92%) volunteered to participate in this study. The participations, in randomized crossover manner, performed a single exercise bout on a cycle ergometer at 50...
Few studies have reported the changes in the peptide YY (PYY) levels in the intestinal tissue of rats with ulcerative colitis (UC) following oral administration of mesalazine and prednisolone. We investigated the effects of these drugs on the intestinal mucosal PYY levels in a rat model of UC. We confirmed that the PYY levels in the rat intestinal mucosal tissue were high in the lower intestina...
Peptide YY (PYY) is secreted as a 36 amino acid, straight chain polypeptide, and is found in greatest concentrations in the terminal ileum, colon and rectum. After secretion, dipeptidyl peptidase IV (DPP-IV) cleaves the N-terminal Tyrosine-Proline residues from PYY(1-36), producing PYY(3-36). PYY(1-36) acts at all four human Y receptors, Y1, Y2, Y4 and Y5, while PYY(336) is a specific Y2 recept...
Short bowel syndrome (SBS) patients developing hyperphagia have a better outcome. Gastrointestinal endocrine adaptations help to improve intestinal functions and food behaviour. We investigated neuroendocrine adaptations in SBS patients and rat models with jejuno-ileal (IR-JI) or jejuno-colonic (IR-JC) anastomosis with and without parenteral nutrition. Circulating levels of ghrelin, PYY, GLP-1,...
abstract the variables affecting the nature of reading comprehension can be classified into two general categories: reader’s variables, and text variables (alderson, 2000). despite the wave of research on vocabulary knowledge as reader’s variable, the role of this knowledge in c-test as a text-dependent test and its interaction with lexical cohesion of the test as a text feature has remained a...
BACKGROUND The gut hormone fragment peptide YY3-36 (PYY) reduces appetite and food intake when infused into subjects of normal weight. In common with the adipocyte hormone leptin, PYY reduces food intake by modulating appetite circuits in the hypothalamus. However, in obesity there is a marked resistance to the action of leptin, which greatly limits its therapeutic effectiveness. We investigate...
Peptide YY(3-36) [PYY(3-36)] is a hormone that is released after meal ingestion that is currently being investigated for the treatment of obesity; however, there are conflicting reports of the effects of PYY(3-36) on energy balance in rodent models. To shed light on this controversy, we studied the effect of PYY(3-36) on food intake and body weight in a nonhuman primate. Intravenous PYY(3-36) i...
educational researchers have provided evidence that teachers’ emotional intelligence has strong effects on various aspects of teaching and learning. yet, in the field of teaching english to speakers of other languages (tesol), inquiry into teachers’ emotional intelligence is nearly limited. given its documented powerful impact on teaching practices and student learning, it is critical to pursue...
Cholecystokinin (CCK), peptide YY (PYY), and ghrelin have been proposed to act as satiety hormones. CCK and PYY are stimulated during meal intake by the presence of nutrients in the small intestine, especially fat, whereas ghrelin is inhibited by eating. The sequence of events (fat intake followed by fat hydrolysis and CCK release) suggests that this process is crucial for triggering the effect...
due to an increase in obesity, the aim of the present study was to examine the effect of 12 weeks of endurance training on body weight, food intake, plasma acylated ghrelin and pyy3-36 in obese male rats. 16 male wistar rats were fed for 9 weeks with a high fat diet (derived from soybean oil) until they reached mean weight of 319±30 g. the rats were randomly divided into control group (n=8) and...
