This volume reports the proceedings of a NATO Advanced Workshop held at Cameron House Hotel, Loch Lomond, Scotland, from May 2 - 5, 1994. The major impetus for this workshop was the realisation, over the past 7 years, that the Epstein-Barr virus is associated with a proportion of cases of Hodgkin's disease and is likely to play an aetiological role. There were four main aims of the workshop: first, to discuss the recent findings in relation to Epstein Barr virus and the aetiology of Hodgkin's disease; second, to relate these data to the epidemiology of Hodgkin's disease; third, to discuss...

Treatment outcome has certainly improved since Stunkard and McLaren-Hume (1959) reviewed the literature and found that less than 25% of obese patients lost 20 pounds or more and less than 5% lost 40 pounds or more. However, one of the few points on which almost all obesity researchers agree is that to date, our results are quite modest and we are generally unsuccessful in promoting effective weight maintenance among obese persons. As the title of a more recent article, "Improving long-term weight loss: Pushing the limits of treatment," (Brownell & Jeffrey, 1987, emphasis added]) suggests,...

This volume contains the written contributions to the proceedings of a workshop related to the pineal gland and its hormones, which was held in Erice, Italy, on June 7 -June 13, 1994. This series of workshops, which began in 1982 and which have been held at four-year intervals since that time, has provided important continuity for advancing the state of knowledge relating to this very important investigative area. The enthusiasm for these conferences has increased steadily, as reflected in the number of individuals applying to attend and in the input of individuals who participate in the...

Space missions subject human beings or any other target of a spacecraft to a radiation environment of an intensity and composition not available on earth. Whereas for missions in low earth orbit (LEO), such as those using the Space Shuttle or Space Station scenario, radiation exposure guidelines have been developed and have been adopted by spacefaring agencies, for exploratory class missions that will take the space travellers outside the protective confines of the geomagnetic field sufficient guidelines for radiation protection are still outstanding. For a piloted Mars mission, the whole...

'nle NATO Advanced studies Institute series "Targeting of Drugs" was originated in 1981. It is now a major international forum, held every two years in cape Sounion, Greece, in which the present and the future of this important area of research in drug delivery is discussed in great depth. Five previous ASIs of the series dealt with drug carriers of natural and synthetic origin, their interaction with the biological milieu, with ways by which the latter influences such interaction and strategies by which milieu interference curtailing the ftmction of drug carriers is circumvented or relieved....

This volume contains the proceedings of the NATO Advanced Study Institute held in Porto Conte (Alghero), Sardinia, September 15-27, 1991. The A. S. 1. was attended by 86 graduate and postgraduate students from 18 different countries, and was hosted by the newly founded International Laboratory of Molecular Genetics of Porto Conte, directed by Prof. Marcello Siniscalco. The A. S. I. was funded by NATO Scientific Affairs Division, the International Union of Immunological Societies, the European Community (Directorate General for Science, Research and Development), the Italian Research Council,...

The data, the information, and even the overarching knowledge necessary for risk assessments of economically important environmental carcinogens come, for the most part, from the applied biological disciplines, e. g., toxicology, epidemiology, biostatistics, etc. The more fundamental biological disciplines, e. g., biochemistry, cell biology, molecular biology, molecular genetics of cancer, etc., have enormous but unrealized potential to improve current cancer risk assessment methods. The objective of this advanced research workshop ARW was to advance the state of the art of cancer risk...

Angiogenesis describes the formation of new blood vessels, which arise as outgrowths from existing vessels. In many physiological processes such as ovulation and wound healing angiogenesis is involved for a relatively short time. Otherwise under normal physiological conditions in the adult organism angiogenesis is an extremely slow process. By contrast in certain disease states such as diabetic retinopathy, arthritis, chronic inflammation, hemangiomas, etc., angiogenesis persists and contributes to the pathology of these disease states. Some 50 such "angiogenic diseases" have been described...

In late May and early June 1991, a NATO Advanced Study Institute was held at a hotel in the hilltop village of San Martino al Cimino a few kilometers from the city of Viterbo in the Lazio region of Italy. The title of the course was the same as this volume and brought together specialists working at all phases of the life span (embryology, infancy, childhood, middle life and senescence) in both animals and humans to exchange ideas, facts and theories in the search for common principles. Such principles could prove important for understanding developmental changes in the central nervous system...

Two techniques were used to estimate the L/M cone ratio, best-fit linear sum of the L- and M-cone spectral sensitivities to heterochromatic flicker photometric spectral sensitivity and psychometric function shape for point source detection of lights of varying wavelength. Data from five color-normal observers run on both paradigms all are consistent with a preponderance of L-cones relative to M-cones though there are individual differences in the estimates of L/M cone ratio. The observers showed congruence in their individual results across technique. In a separate study, the perceptual...
