The Structure and Metabolism of the Pancreatic Islets

The Structure and Metabolism of the Pancreatic Islets: A Centennial of Paul Langerhans' Discovery is a collection of that presents the advancement in the field of pancreatic islet research, particularly in the area of biosynthesis and secretion of insulin. The title also serves as a commemorative material to Paul Langerhans' work.
The text first covers the differentiation and growth of the endocrine pancreas, and then proceeds to tackling a- and ß-cells. Next, the selection deals with the glucose metabolism of the pancreatic islets. The text also discusses the biosynthesis and storage of insulin, along with insulin release. The seventh part details pancreatic islets and diabetes.
The book will be of great use to students, researchers, and practitioners of medicine.
