Introduction: Previous studies have shown that ghrelin inhibits the activity of Hypothalamus –Pituitary – Thyroid (H–P-T) axis. It is also proved that ghrelin increases appetite via Agouti Related Protein and neuropeptide Y pathway, decreases T3 & T4 secretion and inhibits serotonin release from hypothalamic synaptosomes. Serotonin may interact with ghrelin in control of thyroid hormones secr...

BACKGROUND We investigated whether ghrelin is present in human saliva, is produced by salivary glands, and physiologic consequences of these findings. METHODS Expression of ghrelin and specific receptor mRNA was determined by PCR. Proteins were identified by immunoblotting and size-exclusion fast protein liquid chromatography (FPLC) with consecutive RIA. Specific RIAs were used for quantifica...

The croaker Cilus gilberti commonly known as Corvina drum is considered a target marine species for the diversification of Chilean aquaculture. To optimize culture conditions, molecular markers appetite regulation must be examined. Ghrelin, gastrointestinal peptide, plays stimulatory role in food intake mammals and teleost fish. Nevertheless, even though appetite-controlling system relatively w...

Ghrelin is a gut peptide that when acylated is thought to stimulate appetite. Circulating ghrelin concentrations could potentially be used as a predictor of DMI in cattle. The objective of this experiment was to determine the association of circulating ghrelin concentrations with DMI and other production traits. Steers and heifers were fed a finishing diet, and individual intake was recorded fo...

Butyrylcholinesterase (BChE), a plasma enzyme that hydrolyses the neurotransmitter, acetylcholine relatively well, with far lower efficiency than acetylcholinesterase (AChE) but with the capability to degrade a broad range of bioactive esters. AChE is universally understood as essential to cholinergic neurotransmission, voluntary muscle performance, and cognition, among other roles, and its cat...

In cats, the incidence of obesity and diabetes is increasing, and little is known about specific aspects of the endocrine control of food intake in this species. Recent data suggest that ghrelin has an important role in the control of insulin secretion and vice versa, but this role has never been demonstrated in cats. Here we aimed to improve our understanding about the relationship between ins...

objective(s):consumption of high-fat foods is one of the major causes of obesity. physical exercise is a strategy used to counteract obesity. the aim of this study was to investigate the effect of eight weeks endurance training and high-fat diet (hfd) on appetite-regulating hormones in rat plasma. materials and methods:twenty eight male wistar rats were randomly divided into four groups: contro...

OBJECTIVE Recently published animal studies indicate that leptin and ghrelin play a role in puberty initiation and progress as well as in reproduction. The aim of our study was to evaluate the relation of these two hormones to the pubertal maturity and fertility status in patients with beta-thalassemia. DESIGN Blood levels of leptin, acylated ghrelin and sex hormones were determined in 97 (59...
