13. Demanda protéica de juvenis de tambaqui (Colossoma macropomum) após privação alimentar
This study evaluated the effect of energy/protein ratios in the performance, corporal composition and hyperphagia duration of tambaqui juveniles (Colossoma macropomum), after feed privation. Using a complete randomized design, 384 juvenile with average weight and standard deviation of 50,32 0,26g were distributed in 24 tanks of 310L and draftes among eight t

14. Sex-specific compensatory growth in food-deprived Nile tilapia
Female Nile tilapia incubate fertilized eggs in their mouth until they are released as alevins. Consequently, the female may not eat during this period. Thus, it would be expected that female Nile tilapia are more adapted to recovering from fasting than males, which do not display this behavior. To test this hypothesis we conducted an experiment with two gro

15. Phenotypic and behavioral variability within Angelman Syndrome group with UPD
The Angelman syndrome (AS) (developmental delay, mental retardation, speech impairment, ataxia, outbursts of laughter, seizures) can result either from a 15q11-q13 deletion, or from paternal uniparental disomy (UPD), imprinting, or UBE3A mutations. We describe here the phenotypic and behavioral variability detected in eight UPD patients out of a group of 58

16. Stimulation of blowfly feeding behavior by octopaminergic drugs
Adult blowflies (Phormia regina Meigen) injected with the octopaminergic drug demethylchlordimeform (10 μg per fly) exhibited enhanced proboscis extension responses when their tarsae were touched to water or aqueous sucrose. They drank more water than saline-injected control flies did but the quantity imbibed was within the normal fluid intake capacity. The

17. Hypothalamic obesity due to hydrocephalus caused by aqueductal stenosis.
A case is presented of 14 year old female with hypothalamic obesity due to hydrocephalus caused by aqueductal stenosis. Evidence of hypothalamic obesity included 1) acute hyperphagia and weight gain, 2) neuroradiology showed hydrocephalus with focal enlargement of the third ventricle, 3) endocrinological studies revealed hyperinsulinaemia and impaired growth

20. Effects of denervating brown adipose tissue on the responses to cold, hyperphagia and noradrenaline treatment in the rat.
Surgical denervation of the five sympathetic nerves supplying one lobe of the interscapular brown fat of control rats caused small reductions in mass, protein content and the activity of the thermogenic mitochondrial proton conductance pathway (assessed from guanosine-5'-diphosphate (GDP) binding) when compared to the intact lobe. Denervation did not affect

21. Regulation of Food Intake and Gonadotropin-Releasing Hormone/Luteinizing Hormone during Lactation: Role of Insulin and Leptin
Negative energy balance during lactation is reflected by low levels of insulin and leptin and is associated with chronic hyperphagia and suppressed GnRH/LH activity. We studied whether restoration of insulin and/or leptin to physiological levels would reverse the lactation-associated hyperphagia, changes in hypothalamic neuropeptide expression [increased neu

22. A deletion of the HBII-85 class of small nucleolar RNAs (snoRNAs) is associated with hyperphagia, obesity and hypogonadism
Genetic studies in patients with severe early-onset obesity have provided insights into the molecular and physiological pathways that regulate body weight in humans. We report a 19-year-old male with hyperphagia and severe obesity, mild learning difficulties and hypogonadism, in whom diagnostic tests for Prader–Willi syndrome (PWS) had been negative. We ca

23. Integrated control of appetite and fat metabolism by the leptin-proopiomelanocortin pathway
Leptin deficiency results in a complex obesity phenotype comprising both hyperphagia and lowered metabolism. The hyperphagia results, at least in part, from the absence of induction by leptin of melanocyte stimulating hormone (MSH) secretion in the hypothalamus; the MSH normally then binds to melanocortin-4 receptor expressing neurons and inhibits food

24. Melanin-concentrating hormone is a critical mediator of the leptin-deficient phenotype
Energy homeostasis is regulated by a complex network involving peripheral and central signals that determine food intake and energy expenditure. Melanin-concentrating hormone (MCH) plays an essential role in this process. Animals treated with MCH develop hyperphagia and obesity. Ablation of the prepro-MCH gene leads to a lean phenotype, as does ablation
