Novel nutrient based approaches for appetite regulation and obesity
… the daily diet has been shown to contribute to appetite management and thus has the potential to help prevent obesity. These benefits have contributed to the increasing protein consumption observed globally over the past few decades. Plant-based proteins may serve as a more environmentally …

Effects of palatable diets on appetite regulation, appetite peptides and neurogenesis.
… originating from the periphery, involved in the regulation of food intake and of maintaining energy homeostasis. Circulating ghrelin levels increase in times of energy deficiency, such as fasting, signalling hunger whereas circulating leptin levels increase during food intake, signaling …

Hypothalamic mechanisms of appetite regulation involve stress response and epigenetic modification
Appetite regulation is primarily mediated by the hypothalamus, within which many neurotransmitters that regulate feeding are shared by the stress response circuitry. Stressors, especially those occur during critical periods of life, influence epigenetic programming and gene expression in the …

Effects of exogenous and endogenous factors on appetite regulation in broiler chicks and Japanese quail
Understanding how appetite is regulated, via exogenous or endogenous factors, is essential to animal agriculture in order to maximize production capabilities, as well as in human medicine to generate ways to treat conditions such as eating disorders or obesity. The aim of this thesis was to …

Relationships between body mass index, appetite regulation and physical activity during shift-work and night-work
… relationships between body mass index (8M I), appetite regulation, gastrointestinal health and physical activity during shift-work and night-work. In the first study (presented in Chapter 3), a cross-sectional study design was adopted to explore the relationships between 8MI, gastrointestinal …

Effects of exercise, with and without an associated energy deficit, on postprandial metabolism and appetite regulation
… body weights, perhaps by inducing changes in appetite, energy intake and circulating concentrations of 'hunger' hormones. It does, however, remain unclear as to what extent these changes are mediated by exercise per se, or the associated energy deficit and thus what effects exercise coupled …

The role of the free fatty acid, lauric acid, in appetite regulation and its potential as an appetite-suppressant.
… of fatty acids, particularly lauric acid, on the regulation of gastrointestinal function and the suppression of energy intake. One of the first studies in humans to evaluate the effect of fatty acid chain length established that fatty acids with ≥ 12 carbon atoms slow gastric emptying, while fatty …

Differential appetite regulation in lines of chickens selected for high and low juvenile body weight: the role of beta-MSH
Melanocortins play a key role in appetite regulation across species. One such melanocortin, beta-melanocyte stimulating hormone (beta-MSH) is receiving increasing attention for its anorexigenic effects. In chicks selected for low (LWS) and high (HWS) juvenile body weight, beta-MSH differentially …

Dietary macronutrient composition and exogenous neuropeptide Y affect feed intake in brioler chicks
Understanding the central nervous systems role in appetite regulation is crucial to cure the obesity epidemic, which is more prevalent than any disease in the United States. Central appetite regulators, known as neuropeptides, are pivotal in understanding appetite regulation. Neuropeptide Y (NPY), …

Neurological - Molecular Interface in Food Intake and Metabolism in Birds and Mammals
… in understanding the relationship between appetite regulation and adipose tissue deposition in chickens, using chickens selected for low or high juvenile body weight as a model. Appetite regulation in the brain, particularly the hypothalamus, is the main factor governing food intake. …

Mechanisms of hypothalamic regulation of food intake in birds
… public health concerns worldwide. Thus, studying appetite regulation is necessary to provide novel information for the design of solutions for health concerns that stem from altered energy intake. Such information is also relevant for improving chicken health and productivity in an agricultural …

Hypothalamic Mechanisms of Food Intake in Birds
Appetite is a complex behavior which can be influenced by factors within the animal's body as well as the environment around it. Internal factors include hormonal and nutrient concentrations found in the blood stream and subsequent neuropeptide and neurotransmitter signaling in the hypothalamus. …

Clinical Analysis and Review of Literature Associated with Hashimoto's Thyroiditis
… thyroid hormones functions, including mood and appetite regulation (Tomer and Huber 233). However, serious complications such as myxedema coma, Hashimoto's encephalopathy, and even thyroid cancer can occur. While a very effective hormone replacement therapy exists, there is still no cure that …

Activation of the corticolimbic brain by visual food cues; Effect of menstrual cycle phase and mood
… during the menstrual cycle induce changes in appetite and eating behavior. Food intake declines in the peri-ovulatory period when estrogen levels peak, but increases in the luteal phase when progesterone levels increase. In this novel study we introduce a different context in which to study …

Thylakoid membranes from green plants affect appetite and promote body weight loss
… To counteract an increasing body weight gain, regulation of appetite and a controlled food intake is of greatest importance. Simply put, body weight is regulated by the amount of energy ingested, and the amount of energy expended. In todays sedentary lifestyle, we tend to have a much higher …

Corticotrophin Releasing Hormone Modulation of Feed Intake, Gastric Motility, and Behavior in Low and High Body Weight Selected Lines of Chickens
… releasing hormone (CRH) and related compounds on appetite, behavior, and gastric motility in lines of chickens, one selected for low body weight (LWS) and the other high body weight (HWS), was determined. Nucleotide sequence and expression patterns of the CRHr2 receptor, involved in appetite …

Peripheral regulation of food intake in the domestic fowl
… peripheral factors involved with food intake regulation in the domestic fowl. In the first study, the mechanism by which tryptophan depresses food intake was clarified. Intraperitoneal injections of tryptophan methyl ester were demonstrated to inhibit feeding in Single Comb White Leghorn …

Liquid chromatography and mass spectrometry based characterization to understand the role of neuropeptides in various physiological conditions and disease states
… role in several physiological functions such as appetite regulation, nociception, locomotion, reproduction, learning and memory. Given their important role as the molecular messengers of a biological system, there is a lot of interest in the accurate identification and characterization of these …

Molecular and cellular mechanisms of energy homeostasis in birds
… Therefore, integrating knowledge in hypothalamic appetite regulation and adipose tissue metabolism is essential to maintain homeostasis. The aim of this dissertation was to elucidate molecular and cellular mechanisms of energy homeostasis in birds. We determined adipose tissue physiological …

Role of gamma-aminobutyric acid (GABA) in hypothalamic nuclear development
The hypothalamus is involved in energy balance, appetite regulation, stress and anxiety, reproduction including sex behavior, and aggression. It is divided into cell groups based on cell staining, functional similarities and projections. This dissertation looks at the development of three of these …
