We are testing a new system for linking grants to scientists.
The funding information displayed below comes from the
NIH Research Portfolio Online Reporting Tools and the
NSF Award Database.
The grant data on this page is limited to grants awarded in the United States and is thus partial. It can nonetheless be used to understand how funding patterns influence mentorship networks and vice-versa, which has deep implications on how research is done.

Meal-Related Endocrine Responses in Anorexia Nervosa @ Johns Hopkins University
DESCRIPTION (provided by applicant): The proposed research will explore the influence of nutritional status on endocrine responses to a meal beginning with endocrine responses to a meal in a state of starvation, as seen in subjects with anorexia nervosa (AN). It is well established that starvation alters levels of circulating hormones that influence food intake, such as leptin, insulin, ghrelin, and cholecystokinin. However, controlled studies measuring responses to a test meal have not been conducted. Additionally, within the Eating Disorders Program at Johns Hopkins Hospital, the source of our AN subjects, patients are subjected to a period of rapid weight gain. This is a unique physiological situation for which endocrine responses to meals have not been measured. Within this study, we will assess endocrine and subjective responses (hunger, satiety, nausea, anxiety) in human subjects with AN and compare them not only to healthy controls, but also to within subject responses during the process of rapid refeeding and when weight is restored to normal. We will also use a' rodent model of starvation and rapid refeeding to examine changes in peripheral levels of a number of feeding-related peptides and central levels of gene expression NPY, POMC, AgRP, and CRF.

Effects of Dietary Macronutrients On Regulation of Energy Balance @ Purdue University West Lafayette
[unreadable] DESCRIPTION (provided by applicant): Obesity has become a major public health problem worldwide such .that in developed countries 10-20% of the adult population is obese. As the rates of obesity rise, so do associated health care costs. Few effective approaches for reducing body weight exist. Current therapeutic tools such as dietary intervention, exercise regimens, behavioral modification and even pharmacological approaches remain disappointing. The development of alternative, effective dietary regimens has significant clinical implications. Identification of efficacious dietary approaches to weight loss could provide a means by which obesity rates are curbed with significantly fewer health risks than those associated with pharmacologic or surgical interventions. Our recent work has demonstrated that hypothalamic signaling, responses to food deprivation, and sensitivity to peptides that either stimulate or inhibit food intake are dependent upon the background diet of the animal. Our overall hypothesis is that dietary macronutrients differentially influence regulatory responses to food intake. Characterization of how dietary macronutrients influence feeding-regulatory systems in terms of acute and chronic adaptive responses to maintenance on these types of diets may identify novel dietary approaches to weight management. There are three specific aims to this project. The first aim will evaluate the effects of dietary macronutrients on hypothalamic gene expression. The second aim will identify neural and endocrine systems that are affected by low carbohydrate diets. The final aim will assess how chronic exposure to ketone bodies affects feeding, body weight, and endocrine and hypothalamic controls of food intake. These experiments are necessary to further our understanding of how macronutrients influence food intake and body weight, and the mechanisms underlying differential feeding responses to chronic consumption of macronutrient-controlled diets. Furthering the basic understanding of relative contributions of dietary macronutrients to overall food intake and body weight has significant clinical implications in an environment where obesity-related disability and death continue to rise.
