The Transfer of Calcium and Strontium Across Biological Membranes represents the proceedings of a Conference on The Transfer of Calcium and Strontium Across Biological Membranes, held in Cornell University, Ithaca, New York on May 13-16, 1962. This book is organized into seven sections encompassing 22 chapters, and deals first with some of the properties of biological membranes, the general aspects of ion transport, and chelation of divalent cations. These subjects are all important to understand the transfer of calcium and strontium across membranes. The subsequent sections are devoted to the physiological and nutritional aspects of intestinal absorption, with a particular emphasis on the influence of vitamin D and other nutritional factors on the absorption of calcium and strontium. A section describes the biological transfer and movement of calcium and strontium across kidney, mammary gland, nerve, and muscle. The last section examines the behavior of chronically ingested radiostrontium in animals. This section also provides an overview of strontium and calcium metabolism principles.
