Glucagon III complements Glucagon I and II published in 1983 in this series as Vols. 66/I and II. These three volumes truly represent a "glucagon encyclopedia" and as such have no competitors in the scientific literature worldwide. In this volume, the most recent data on glucagon molecular biology are reviewed together with clinically relevant information on the role of glucagon in the pathophysiology of diabetes, the place of glucagon in medical imaging or in emergency medicine. Chapters are devoted to newly identified members of the glucagon family such as glucagon-like peptide-1 (GLP-1) and oxyntomodulin. Glucagon III is a comprehensive review of all information published on this important hormone since 1983 and is the reference book on the subject.
