Food intake in birds: hypothalamic mechanisms
… Understanding the physiological regulation of food intake is important for improving nutrient utilization efficiency in agricultural species and for understanding and treating eating disorders. Knowledge about appetite in birds has agricultural and biomedical relevance and provides evolutionary …

Restriction of Food Intake by Dorsomedial Hypothalamus
… deficient ob/ob mice eat voraciously and their food intake is markedly reduced by leptin treatment. Leptin acts in part by regulating the activity of AGRP neurons and POMC neurons in the arcuate nucleus and neurons in other brain regions. In these dissertation, I will describe how we identify …

Hypothalamic Mechanisms of Food Intake in Birds
… molecular mechanisms associated with food intake in broiler type chickens and Japanese quail, and the effect of HAT exposure on food intake in broiler type chickens. Broiler type chickens have undergone intense artificial selection for traits that promote rapid growth, consequently …

Central cannabinoid regulation of food intake in chickens
… controlling body weight and regulation of food intake. Several of the neuropeptides present in hypothalamic nuclei contribute to energy balance and food intake regulation. Endogenous cannabinoid and cannobinoid receptors are found in the hypothalamus and are associated with the regulation …

Mechanisms of hypothalamic regulation of food intake in birds
… health concerns that stem from altered energy intake. Such information is also relevant for improving chicken health and productivity in an agricultural setting. The objective of this dissertation research was to determine the hypothalamic mechanisms underlying appetite regulation in birds. In …

Central control of food intake in the domestic fowl
… act upon the central nervous system to control food intake. Plasma collected from free-feeding and 24-hour fasted leghorn cockerels was lyophilized, reconstituted to 2, 4, or 5 times the original concentration, and injected, via a stereotaxically implanted 23 gauge stainless steel guide cannula, …

Peripheral regulation of food intake in the domestic fowl
… to examine 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 …

Effects of exercise on hunger, food intake and energy expenditure
… chronic effects of exercise on hunger, energy intake and expenditure. Cross-sectional studies examined the effect of 60 min of moderate-intensity cycling on immediate and subsequent three day energy intake and expenditure in active and inactive men (study one) and women not using hormonal …

Time of Food Intake and its Effect on Physical Performance
… been some disagreement on the effects of time of food intake on subsequent performance. Times from one-half hour to four hours have been suggested as the ideal time for a pre-event meal to be ingested to have the greatest positive effect on athletic performance.</p> <p>Statement of the …

Exploring circadian rhythms, food intake, and their interactions in marine invertebrates
… physiological responses to tolerate variation in food availability. Most of our mechanistic knowledge of these processes comes from terrestrial mammals and insects, while there are major knowledge gaps for marine invertebrates. My dissertation focuses on the interactions of circadian rhythms and …

Acute Psychological Stress and Food Intake in Humans: A Scoping Review
… or no change in the homeostatic mechanisms of food intake (e.g., appetite, appetite hormones, food intake). However, homeostatic control can be overridden by hedonic (or pleasure-inducing) mechanisms. Stress can increase cravings of unhealthy palatable food causing alterations in food …

… physiological responses to tolerate variation in food availability. Most of our mechanistic knowledge of these processes comes from terrestrial mammals and insects, while there are major knowledge gaps for marine invertebrates.

Hypothalamic Regulation of Food Intake in Obese and Anorexic Avian Models
… demonstrated that these lines have differential food intake threshold responses to a range of intracerebroventricular (ICV) injected neurotransmitters. The major brain region regulating homeostatic regulation of appetite is the hypothalamus, and hence this dissertation was focused on …

Neurological - Molecular Interface in Food Intake and Metabolism in Birds and Mammals
… Energy homeostasis depends on energy intake and energy expenditure. Factors controlling the development of different adipose tissue deposits in the body and their distinct metabolic phenotypes are of considerable interest from both an agricultural and biomedical perspective. Following …

Tracking and counting motion for monitoring food intake based on depth sensor
… are not tracking and detecting the right calorie intake for weight loss, but currently used tools such as food diaries require users to manually record and track the food calories, making them difficult to be utilized for daily use. Therefore, this project developed a new tool that counts the food …

Serotonin mediated effects on food intake, feeding body weight and subjective variables
… inhibitor and anti-depressant fluoxetine on food intake and choice, body weight and subjective states in both non-depressed normal-weight and obese subjects. The third and final impetus arose from the observation that, in rats, the expression of meal-induced satiety offered a background …

Children's food intake and parental attitudes in single-parent and nuclear families
… parental nutrition knowledge, and the food consumption of one randomly selected six-to eight-year-old child per family were investigated in a group of 66 nuclear families and 17 single-parent families. Each family recorded three consecutive, non-weekend days of their child's food and …
