Cell Regulation by Intracellular Signals
In 1980, the IVth International Cyclic Nucleotide Conference was held in Brussels. As this meeting attracted many investigators involved in cyclic nucleotides and calcium role in intracellular regulation, it was thought that this opportunity could be used to organize, prior to the Congress, an in-depth introductory course on the subject. This was carried out as a NATO Advanced Study Institute. The participants included Ph. D. students and M. D. s engaged in a research training, but also fully trained and well known researchers who wanted a refresher course on the whole subject. During the course, most of the participants and lecturers asked to be provided with a text summarizing the basic le...
Targeting of Drugs
Successful drug use in biology and medicine is often prejudiced by the failure of drugs that are otherwise active in vitro to act as efficiently in vivo. This is because in the living animal drugs must, as a rule, bypass or traverse organs, membranes, cells and molecules that stand between the site of administration and the site of action. In practice, however, drugs can be toxic to normal tissues, have limited or no access to the target and be prematurely excreted or inactivated. There is now growing optimism that such problems may be resolved by the use of carrier systems that will not only protect the non-target environment from the drugs they carry but also deliver them to where they are needed or facilitate their release there. Carrier systems presently under investigation include antibodies, glycoproteins, cells, reconstituted viruses and liposomes. Recent advances in the chemistry of cell receptor and receptor-recognising molecules, llnmunology, and natural and artificial membranes have revealed a multitude of ways in which such carrier systems can be modified or improved upon.
Post-Harvest Physiology and Crop Preservation
Emphasis in agricultural research for many years has concen trated on crop production. This emphasis has become more important in recent years with the realization that the population worldwide is outstripping the food supply. There is, however, another side to increasing the availability of the food supply. This simply involves preservation of the harvested crop·for human consumption. The losses incurred in harvesting, handling, transportation, storage and marketing crops have become a greater problem as the distance from the farm to the ultimate consumer increases. In the Western world where modern transportation, storage facilities, and marketing technology are widely used, post-harvest ...
Structural Molecular Biology
Structural biology is undergoing a revolution in both the sophistication of new biophysical methods and the complexity of problems in biomolecular structure and organization opened up for study. These changes are directly attributable to major advances in computer technology, computational methods, development of high intensity synchrotron radiation sources, new magnetic resonance methods, laser optical techniques, etc. Structure-function problems previously considered intractable may now be solved. As this area of specialisation continues to expand, there is a need to review the various physical methods currently being used and developed in struc tural molecular biology. At the same time th...
Chemical Carcinogenesis
During October 18-30, 1981, the second course of the International School of Pure and Applied Biostructure, a NATO Advanced Study Institute, was held at the Ettore Majorana Center for Scientific Culture in Erice, Italy, co-sponsored by the International Union Against Cancer, the Italian League Against Cancer, the Italian Ministry of Public Education, the Italian Ministry of Scientific and Technological Research, the North Atlantic Treaty Organization, the Italian National Research Council, the Sicilian Regional Government and two pharmaceutical Companies (Zambeletti and Farmitalia). The subject of the course was "Chemical Carcino genesis" with participants selected world-wide from 18 differe...
Neurotransmitter Interaction and Compartmentation
The NATO Advanced Study Institute held in the Hotel Metropole Llandrindod Wells, Powys, Wales from July 26th to August 4th 1981 provided an excellent platform for presentation and appraisal of our current knowledge of neurotransmitter systems. The proceed ings comprise the present volume and these were arranged to allow study of the pathways and the interactions of specific transmitter systems, one with another, in the various sub-regions of the central nervous system. In addition several of the key factors involved in neurotransmitter release were highlighted. These include the structural and molecular organisation of the nerve terminal, its organelles (such as vesicles, neurotubules and sy...
Biological Effects and Dosimetry of Nonionizing Radiation
During the last 35 years, there has been considerable develop ment and increase in the number of devices that emit nonionizing radiant energies. These energies such as radiofrequency including microwaves are used in all sectors of our society for military, industrial. telecommunications, medical, and consumer applications. This increase in sources of nonionizing radiant energies has resulted in growing interest on the part of government regulatory agencies, industrial and military physicians, research workers, clinicians, and environmentalists. Although there is information on biologic effects and potential hazards to man from exposure to microwave/radiofrequency energies, considerable confu...
Agriculture, Environment and Sustainable Development
This volume is intended to provide a comprehensive understanding of recent innovations related to the study of agricultural and environmental management for sustainable development. The book clearly identifies why the fight to achieve sustainable development in agricultural production must be fought along a broad multidisciplinary front to overcome issues such as soil erosion, poor water quality, pesticide contamination, and food insecurity. Readers are given a broad exposition of the trends and current practices of basic principles on sustainable agriculture, along with a detailed understanding of the use of sustainable agriculture to develop environmentally sustainable food production syst...
Factors in Formation and Regression of the Atherosclerotic Plaque
Interest in the field of atherosclerosis research has broadened in recent years. However the main focus remains on the physiopathology of the arterial wall and on its interaction with blood constituents. The purpose of this NATO Advanced Study Institute on "Factors in Formation and Regression of the Atherosclerotic Plaque" was to discuss the following points: a) The physiopathology of the arterial wall; b) Animal models; c) Methods of studying the progression and regression of atherosclerotic lesions quantitatively; d) The role of lipoproteins, platelets, smoke, alcohol, etc. in the formation of atherosclerotic lesions; e) The pharmacological and dietary control of "risk factors." This volume is a collection of the most relevant presentations on these topics. We hope it will provide a background for young scientists as well as a stimulus for further research to biologists and clinicians. We wish to acknowledge the support of NATO and the Nutrition Foundation of Italy in organizing this Advanced Study Institute.
