        • Body Fat: Hidden Organ, New Source of Hormonal Regulation - Sebastien G. Bouret, University of Southern California

          Body Fat: Hidden Organ, New Source of Hormonal Regulation Sebastien G. Bouret, University of Southern California Abstract: The devastating health and emotional impact of obesity is no longer confined to just adults. Recent statistics show that 22 million children under five are estimated to be overweight worldwide. Recent findings in pediatric research have uncovered a significant piece of the obesity puzzle: beyond merely the effects of diet and lack of exercise, a child’s risk of obesity can also be determined during the critical perinatal stage, that is, the period during and around birth. Central to this field is the concept of “perinatal programming”, defined broadly as a process where a stimulus at a critical period of development may have long-term or even lifetime effects. Data from both human studies and animal models have revealed that obesity risk is greatly influenced by two major factors: the nutritional and hormonal conditions of the mother during pregnancy and the nutritional and hormonal conditions of the child in early infanthood, with both perinatal malnutrition as well as over-nutrition being risk factors for the child becoming overweight or obese. We have also known for decades that the brain, and particularly a region of the brain called the hypothalamus, plays a key role in regulating food intake and body weight. A collection of brain cells (neurons) in the hypothalamus coordinates our need to eat in relation to how well our body is fed via cross talk with hormone signals arising from the gastrointestinal tract and adipose tissue. The critical brain growth and development period takes place during the intra-uterine life up to the first years of life. During this time, the brain is highly sensitive and a change in environment, particularly in regard to hormones and nutrition, could have an adverse effect on the organ. Experimental evidence suggests that development of programming in brain circuitry that controls appetite by the perinatal environment could predispose an individual to become overweight or obese. For example, we have recently shown that the fat hormone leptin and the gut hormone ghrelin work on the brain (on the hypothalamus) during early life to regulate the growth of nerve cells (axons) that control eating. In addition, nutritional manipulation of hormone secretion during perinatal life has generated considerable concern, and the developing brain appears to be a particularly sensitive target for these environmental changes, with both perinatal undernutrition and overnutrition having adverse consequences on the architecture of brain circuits involved in appetite regulation. These intriguing results suggest that predisposition to obesity might be hardwired at or around birth and that adequate nutrition during early life is essential for proper development of brain centers involved in food intake and body weight regulation.

            Michigan Tech College of Engineering Distinguished Speakers Series "New Frontiers in the Pharmaceutical and Medical Sciences: Advanced Intelligent Hydrogels for Treatment of Diabetes, Cancer and Multiple Sclerosis" Nicholas A. Peppas, Sc.D. Fletcher Stuckey Pratt Chair in Engineering Professor of Biomedical Engineering, Chemical Engineering and Pharmacy Chairman, Biomedical Engineering Department Director of Center on Biomaterials, Drug Delivery, and Bionanotechnology The University of Texas at Austin Abstract Engineering the molecular design of intelligent hydrogels by controlling recognition and specificity is the first step in coordinating and duplicating complex biological and physiological processes. We address design and synthesis characteristics of nover crosslinked networks capable of protein release as well as artificial molecular structures capable of specific molecular recognition of biological molecules. Recent developments in protein delivery have been directed towards the preparation of targeted formulations for protein delivery to specific sites, use of environmentally-responsive polymers to achieve pH- or temperature-triggered delivery, usually in modulated mode, and improvement of the behavior of their mucoadhesive behavior and cell recognition. Molecular imprinting and microimprinting techniques, which create stereo-specific three-dimensional binding cavities based on a biological compound of interest can lead to preparation of biomimetic materials for intelligent drug delivery, drug targeting, and tissue engineering. We have been successful in synthesizing novel glucose-binding molecules based on non-covalent directed interactions formed via molecular imprinting techniques within aqueous media. Short Biography Nicholas A. Peppas is the Fletcher S. Pratt Chaired Professor in the Departments of Chemical, Biomedical Engineering and Pharmacy, and Chairman of the Department of Biomedical Engineering of the University of Texas at Austin. Peppas is a world leader in biomaterials, polymer physics, drug delivery and bionanotechnology. The multidisciplinary approach of his research blends modern molecular and cellular biology with engineering to generate the next-generation of medical systems and devices for patient treatment. He set the fundamentals and rational design of drug delivery systems over the past forty years and developed models of drug and protein diffusion in controlled release devices and biological tissues. In 2012 he received the Founders Award of the National Academy of Engineering, the highest recognition of the Academy, for these contributions to the field. Peppas is a member of the Institute of Medicine of the National Academies, the National Academy of Engineering, the National Academy of France, the Royal Academy of Pharmacy of Spain, and the Academy of Texas. He has been recognized with awards from AIChE (Founders Award, William Walker Award, Institute Lecture, Jay Bailey Award, Bioengineering Award, Materials Award), the Biomedical Engineering Society (Distinguished Scientist Award), the American Institute of Medical and Biological Engineering (Galletti Award), the Society for Biomaterials (Founders, Clemson and Hall Awards), the Controlled Release Society (Founders, Heller and Eurand Awards) and other societies. In 2008, AIChE named him on of the One Hundred Chemical Engineers of the Modern Era. He is President of the International Union of Societies of Biomaterials Science and Engineering, and Past-Chair of the Council of BME Chairs. Previously, he served as President of SFB and the Controlled Release Society. He is a fellow of AAAS, AIChE, APS, ACS, MRS, SFB, BMES, AIMBE, CRS, AAPS, and ASEE. He is a highly cited scientist (50,000 citations, H=110) and has supervised the research of 95 PhDs and about 180 postdocs and graduate students. Peppas holds a Dipl. Eng. from the NTU of Athens (1971), a Sc.D. from MIT (1973), and honorary doctorates from the Universities of Ghent, Parma, Athens and Ljubljana.
