Question: What association hosted the Banting Lecture which was named after the co-discoverer of insulin?
Context: Prof John James Rickard Macleod, FRS FRSE LLD (6 September 1876 – 16 March 1935) was a Scottish biochemist and physiologist.  He devoted his career to diverse topics in physiology and biochemistry, but was chiefly interested in carbohydrate metabolism.  He is noted for his role in the discovery and isolation of insulin during his tenure as a lecturer at the University of Toronto, for which he and Frederick Banting received the 1923 Nobel prize in Physiology or Medicine.  Awarding the prize to Macleod was controversial at the time, because according to Banting's version of events, Macleod's role in the discovery was negligible.  It was not until decades after the events that an independent review acknowledged a far greater role than was attributed to him at first. Glory Enough for All is a 1988 television movie directed by Eric Till and written by Grahame Woods depicting the discovery and isolation of insulin by Frederick Banting and Charles Herbert Best.  It was the winner of nine 1989 Gemini Awards.  The film stars R. H. Thomson as Banting, and Robert Wisden as Best.  It is based on the books "The Discovery of Insulin" and "Banting: A Biography" by historian Michael Bliss. The Flame of Hope is an eternal flame that honours Sir Frederick Banting's discovery of insulin, as well as all those who have been affected by diabetes.  Simultaneously, it serves as a reminder that insulin controls diabetes but does not cure it; ultimately, it stands for the hope that a cure will soon be found. Elixir is a children's historical novel by Canadian author Eric Walters.  It takes place in the University of Toronto in Toronto, Ontario in the year of 1921 and is based on the discovery of insulin by Frederick Banting and Charles Best.  The story is told from Ruth's point of view. Moses Barron (188422 December 1974) was a medical doctor and researcher.  Born in Russia, he was brought to the United States by his parents at age 5 and grew up in Minnesota.  He received a medical degree from the University of Minnesota in 1911.  He served as a medical officer in France in World War 1, and later became a Clinical Professor of Medicine at the University of Minnesota.  In 1920 he published an article, "The relation of the Islets of Langerhans to Diabetes," which noted the importance of the islet cells of the pancreas in relation to diabetes.  It inspired Dr. Frederick Banting's research in diabetes, which led to the Nobel Prize winning discovery of insulin as a treatment for diabetes.  Barron retired as professor in 1952. The Banting Lectures are a yearly series of research presentations given by an expert in diabetes.  The name of the lecture series refers to Frederick Banting, who was a seminal scientist, doctor and Nobel laureate for the co-discovery of insulin.  The lectures are currently hosted by the American Diabetes Association. Banting House is known as “The Birthplace of Insulin.”  Located at 442 Adelaide St. N. in London, Ontario, Canada, it is the house where Sir Frederick Banting woke up at two o’clock in the morning on October 31st, 1920 with the idea that led to the discovery of insulin. Sir Frederick Banting Secondary School is a high school located in London, Ontario, Canada.  It was officially opened in 1969, and has history of excellence in the arts, in sports and in community service.  Banting is recognized for having a strong French Immersion program and a music program.  The school is named after Sir Frederick Banting, who won the Nobel Prize for the discovery of insulin in 1923.  The school participated in CBC's mini-series, "The Greatest Canadian", in which Sir Frederick Banting was nominated. Sir Frederick Grant Banting {'1': ", '2': ", '3': ", '4': "} (November 14, 1891 – February 21, 1941) was a Canadian medical scientist, physician, painter, and Nobel laureate noted as the co-discoverer of insulin and its therapeutic potential. W. Timothy Garvey (born 1952) is Butterworth Professor of Medicine and Chair of the Department of Nutrition Sciences at the University of Alabama at Birmingham, and is director of the NIH-funded UAB Diabetes Research and Training Center.  Garvey has been a principal contributor to our understanding of the role of the glucose transport system and glucose transporter proteins in human insulin resistance, and the role of adiponectin in the metabolic syndrome.  He has identified gene families that contribute to insulin resistance in human muscle insulin using cDNA microarray, e.g., NR4A orphan nuclear receptors and the tribbles gene family, and is using mitochondrial proteomics to better define mitochondrial defects that impair substrate oxidation.  Garvey has provided service as a member of national research review committees for the Juvenile Diabetes Research Foundation, the American Diabetes Association, the VA Merit Review Program, and the National Institutes of Health.  Garvey serves on the editorial boards of the "Journal of Clinical Endocrinology" and "Metabolism and Diabetes".  He is a member of the American Society for Clinical Investigation, the Association of American Physicians, the Endocrine Society, and the American Diabetes Association.
