Introduction: Ghrelin, increases food intake, decreases T3 and T4 concentrations and stimulates insulin release, while leptin reduces food intake and suppresses appetite. Considering the importance of thyroid hormones, ghrelin and leptin in body metabolism, the purpose of this study was to investigate the effect of interactions between ghrelin and leptin (injected via ICV route) and plasma T...

Stress, mood, and eating behavior play an important role in appetite weight regulation. In particular, ghrelin, as the only known orexigenic hormone, has been suggested to be influential mediator food intake responses stress. The exact of ghrelin hypothalamic–pituitary–adrenal axis is still unknown further challenged by psychological aspects stress behavior. This study aimed assess effect chron...

The effects of feeding corn or rice, either raw or heat processed (HP), on apparent total tract digestibility (ATTD) and apparent ileal digestibility (AID) of nutrients and on insulin and ghrelin concentrations in the serum were studied in young pigs. Pigs were weaned at approximately 23 ± 3 d of age and weighed 7.4 ± 1.2 kg. Each of the 4 treatments was replicated 9 times, and the experimental...

background ghrelin and obestatin are orexigenic and anorexigenic peptides, respectively. it appears that an accurate balance between theses peptides is important for regulating energy homeostasis and body weight. objectives the aim of this study was to identify the possible mechanisms by which circuit resistance training influences energy homeostasis and weight control. patients and methods twe...

Ghrelin (Grln) is a peptide hormone that is predominantly produced in the stomach and stimulates appetite and induces growth hormone (GH) release. We have previously reported that ghrelin is also expressed in T cells and exerts prothymic and anti-inflammatory effects. However, the biologic relevance of T cell-derived ghrelin remains to be determined. Here, we report that acylated-bioactive ghre...

Regulation of energy homeostasis requires precise coordination between peripheral nutrient-sensing molecules and central regulatory networks. Ghrelin is a twenty-eight-amino acid orexigenic peptide acylated at the serine 3 position mainly with an n-octanoic acid, which is produced mainly in the stomach. It is the endogenous ligand of the growth hormone secretagogue (GHS) receptors. Since plasma...

Obesity endangers the lives of millions of people worldwide, through comorbidities such as heart disease, cancers, type 2 diabetes, stroke, arthritis, and major depression. New approaches to control body weight remain a high priority. Vaccines traditionally have been used to protect against infectious diseases and, more recently, for unconventional targets such as drug addiction. Methodologies ...

AIMS/HYPOTHESIS The mechanisms underlying glucagon-induced satiety are incompletely understood. The glucagon-induced reduction in total ghrelin exerted at the hypothalamo-pituitary level might be responsible for this effect. Here we investigated glucagon-suppressive effects on circulating total and acyl-ghrelin, both in obesity and in type 1 diabetes mellitus (T1DM), with respect to the role of...
