PURPOSE Easy access to unhealthy foods is believed to contribute to the current overweight epidemic. It remains unclear, however, how access to unhealthy foods is related to self-regulation of food intake. This study tests the hypothesis that using self-regulation strategies buffers the negative influences of easy access to unhealthy foods. METHODS Cross-sectional survey data from 2764 adoles...

a kind of growth hormone secretagogue (ghs), ghrelin, was first isolated from the rat stomach and plays a major role in the activation of the growth hormone secretagogue receptor 1a (ghs-r1a) resulting the release of growth hormone (gh). the preproghrelin gene is placed on chromosome 3, at locus 3p25 –2 in humans and constitutes five exons and three introns. ghrelin is most plentifully expresse...

the role of endogenous histamine and h1, h2 and h3 central receptors on food intake in broiler chickenswas investigated. for this purpose, a probe was used to manipulate the concentration of endogenoushistamine by intracerebroventricular (icv) injection of thioperamide, an h3 receptor antagonist, and r-α-methylhistamine, an h3 receptor agonist and subsequently the effects of brain histaminergic...

introduction: nutrition plays an important role in the protection and promotion of health. to plan and implement programs aiming at improving community nutritional status, a knowledge of the existing situation is essential. the aim of this cross-sectional study was to determine food and nutrient intakes of the inhabitants in tehran university of medical sciences population laboratory. methods: ...

the role of histamine in the regulation of food and water intake in mammals and birds of the review, this study evaluated the effects of intraperitoneal administration of chlorpheniramine as histamine h1-receptor antagonist, in broiler chicks on feed intake and satiety in water and was hungry. 32 male ross broiler chicks reared in groups of four weeks, 16 samples (control and test) were then in...

Ghrelin, produced in the stomach, acts on growth hormone secretagogue receptors (GHSRs) in hypothalamic neurons to potently increase food intake. However, male mice with deletions of ghrelin (Ghrl-/- mice) or GHSR (Ghsr-/- mice) display normal growth and regulation of food intake. Furthermore, adult Ghrl-/- mice display a normal sensitivity to high-fat diet-induced obesity. These findings from ...

STRUBBE, J. H. AND J. GORISSEN. Meal patterning in the lactating rat. PHYSIOL. BEHAV. 25(5) 775-777, 1980.The present study was undertaken to investigate feeding behaviour of the lactating rat over the day-night cycle. Food intake was recorded continuously in six pregnant and subsequently lactating female rats with 10 pups each. Although there was a twofold increase of food intake during the fi...
