Buch. Zustand: Neu. Neuware - Breast cancer, being a disease with very high prevalence in the female population, has permanently attracted the attention of biologists, biochemists, pathologists, surgeons, and oncologists. In the U.S. alone approximately 120,000 new cases are diagnosed and 37,000 deaths a year are recorded as an outcome. Early diagnosis, clear cut prognosis and the hope of new therapeutic approaches has spurred the enthusiasm of researchers, who with the advent of newer methodologies, tried to employ it in different approaches to the breast cancer patient. In spite of the efforts devoted towards the creation of new approaches, reagents and procedures taking advantage of special characteristics of the breast tissue were slow to come. In general, most diagnostic and prognostic techniques were those shared and applied to other carcinomas. In the early seventies we discovered the first sets of antigens associated with breast epithelial tissue both in the mouse and the human. The recognition of such group of molecules, present in the milk fat globule membrane, gave impetus to several studies in these areas. These mammary cell surface antigens proved useful in several diagnostic approaches such as radioimaging, histochemical and serum assay procedures. However, the apparently inherent limitations of polyclonal antibodies reduced the impact of these novel approaches.

Buch. Zustand: Neu. Neuware - This volume represents a part of the scientific proceedings of the Sixth Annual Meeting of the American Section of the International Society for Heart Research that was held in Oklahoma City from September 13-15, 1984. The chapters have been grouped according to the content of invited symposia on cardiovascular topics ranging from electrophysiology, autonomic control of the circulation, aging of the myocardium, mechanisms of cardiovascular injury, cultured heart cell studies, etc. Abstracts of all the papers presented at this meeting are included in Volume 16 (Supp. 1) of the Journal of Molecular and Cellular Cardiology. Since our understanding of the pathobiology of cardiovascular injury requires integrating knowledge from both basic and clinical sciences, the information presented in this volume extends from fundamental biochemical processes to pharmacological agents required to treat complex cardiac arrhythmias. At the molecular level, the structural lipids of the sarcolemma may be altered during myocardial ischemia; the role of free radicals in this process is one emerging area of active study. At the subcellular level, plasma membranes provide the anatomical basis for maintenance of optimal potentials of excitable cells; the anatomy and physiology of the sarcolemma ultimately determines the response to drugs and metabolic perturbants. At the cellular level, much progress has been made in our understanding of cultured and adult myocytes during ischemia and hypoxia; in particular, the electrophysiology of these model systems is well understood and several chapters address this approach.
