Jerboas are wild rodents exhibiting exceptional adaptation to their desert environment. Under harsh autumn conditions, they shut down reproduction, increase body weight and hibernate, while during spring they become sexually active even under negative energy-balance. We recently reported that these rhythms are associated with synchronized changes in genes expressing reproductive (Kiss1, Rfrp) a...
Recently, glucagon-like peptide-1-(7-36) amide (GLP-1) and leptin have been implicated in the regulation of food intake. In the present study, we compared the effects of third ventricular administration (i3vt) of leptin (3.5 micrograms) and GLP-1 (10.0 micrograms) on short-term food intake and c-Fos-like immunoreactivity (c-FLI) in hypothalamic, limbic, and hindbrain areas in the rat. Relative ...
Unrestrained rats received continuous and discontinuous intravenous infusions of nutritive substances over long periods, and the effects on energy regulation were examined. Oral food intake was decreased by all glucidic infusions, but by less than the theoretical (caloric) value of the infused substances. A residual oral food intake thus persisted when the energy needs were supplied intravenous...
T HE mechanisms regulating feed intake appear to be the same mechanisms that control energy exchange. The physiological functions brought into play are numerous and involve chemosensitive areas, reflex responses and integrative function of the central nervous system. Aside from the primary physiological factors limiting feed intake, a close relationship exists in ruminants between the content o...
BACKGROUND Preschool-aged children consistently self-regulate energy intake by adjusting food intake to reflect the energy density of the diet. However, only select adults demonstrate self-regulation skills related to energy density cues. OBJECTIVE The objective was to examine the developmental characteristics of non-Hispanic white and Hispanic children's self-regulation of energy intake and ...
Feeding behavior is one of the most essential activities in animals, which is tightly regulated by neuroendocrine factors. Drosophila melanogaster short neuropeptide F (sNPF) and the mammalian functional homolog neuropeptide Y (NPY) regulate food intake. Understanding the molecular mechanism of sNPF and NPY signaling is critical to elucidate feeding regulation. Here, we found that minibrain (mn...
Melanocortins play a critical role in appetite and body weight regulation, because manipulations of this pathway can lead to the development of obesity in several animal models. The purpose of this study was to use a melanocortin receptor agonist and antagonist to evaluate the involvement of melanocortins in feeding, energy metabolism, and body weight regulation in lean and obese Zucker rats. C...
OBJECTIVE Kinins mediate pathophysiological processes related to hypertension, pain, and inflammation through the activation of two G-protein-coupled receptors, named B(1) and B(2). Although these peptides have been related to glucose homeostasis, their effects on energy balance are still unknown. RESEARCH DESIGN AND METHODS Using genetic and pharmacological strategies to abrogate the kinin B...
The electrolytic lesions of the ventro-medial part of the amygdala in cats increased the cereal and milk intake and reduced the ingestion of meat. In consequence hyperphagia, hyperdipsia of milk and a significant increase of the total caloric intake developed only in cats fed cereal and milk. In cats fed milk and meat hyperdipsia and hypophagia, both of about 50 percent appeared, causing a smal...
BACKGROUND The regulation of energy intake is a complex process involving the integration of homeostatic signals and both internal and external sensory inputs. The objective of this study was to examine the effects of short-term overfeeding on the neuronal response to food-related visual stimuli in individuals prone and resistant to weight gain. METHODOLOGY/PRINCIPAL FINDINGS 22 thin and 19 r...
