The variety of viewpoints expressed in this book illustrate the many contro versies surrounding MDMA 1]. On the one hand, the proponents ofMDMA use believe this agent offers a unique psychoactive effect that may have important clinical applications, especially in the field of psychotherapy. On the other hand, the scientific data concerning the neurotoxic effects of the drug are unequivocal. The most striking feature of the human information of MDMA is the paucity of data that has been generated on the drug since it was patented in 1914. As pointed out by Beck (Chapter 6) and others, a clear...

This series will include monographs and collections of studies devoted to the investigation and exploration of knowledge, information, and data processing systems of all kinds, no matter whether human, (other) animal, or machine. Its scope is intended to span the full range of interests from classical problems in the philosophy of mind and philosophical psychol ogy through issues in cognitive psychology and sociobiology (concerning the mental capabilities of other species) to ideas related to artificial intelligence and computer science. While primary emphasis will be placed upon theoretical,...

Professor Donald Davidson is one of the most innovative and influential recent philosophers. Ranging over a variety of topics in the philosophy of language, philosophy of mind and epistemology, his system of thought is unified by his inquiries into the nature of interpretation and understanding the speech and behavior of others.
Together with its introduction, Language, Mind and Epistemology examines Davidson's unified stance towards philosophy by joining American and European authors within a collection of essays, published here for the first time. The authors discuss the...

G. Petursson and Rikke Hoff-J0rgensen The concept of slow viral infections was first put forward in 1954 by Dr. Bjorn Sigurdsson, an Icelandic physician who had been studying some sheep diseases which were introduced into Iceland with the importation of a foreign breed of sheep in 1933. Sigurdsson's main criteria for defining slow infec tions were a very long initial period without clinical signs lasting months or even years following infection and a rather regular protracted, progres sive course, once clinical symptoms had appeared, usually ending in serious disease or death. Sigurdsson...

One of the most exciting developments in medicine in this century has been the discovery of opioid receptors and their pharmacology. The breadth of know- edge derived from such discovery has truly changed the practice of medicine today. The acceptance by the clinicians of the research data obtained by the basic scientist on spinal opioids is truly amazing. The clinical sequelae of the discovery of opioid receptors has been the development of the technique of intraspinal administration of opioids. In the last decade much has been written about indications, effects, and side effects of...

When established four years ago, the scope of this international series in electron microscopy essentially was to provide an opportunity for the pUblication of selected review contributions by specialists in ultrastructural research. Previous volumes presented over the last three years have focused on special topics of present interest in 'ontemporary biomedicine such as endocrine cells, reproduction, and connective tissues. In these fielCls, in fact, integrated methods of electron microscopy have contributed much to generate new ideas and concepts of general value in both basic and clinical...

In the last few years, the adoption and worldwide proliferation of clinical procedures for medically assisted conception have been associated with the examination and analysis of spermatozoa, oocytes and early embryos under a variety of in vivo and in vitro conditions. These analyses have enabled correlations to be made between the behavior of gametes, the pattern of early embryonic development and the initiation of a normal pregnancy. Collectively, the findings have not only enormously increased our understanding of the process of early human development, but also have provided new insights...

Recent advances in electron microscopy have opened up new dimensions and perspectives in the field of morphology, and these are presently being integrated with biochemical and physiopathological phenomena occurring in cells, tissues, and organs. Methods such as freeze-fracture, freeze-etching, scanning, and high-voltage electron microscopy have contributed immensely to this progress, as well as to the study of smooth muscle tissue and contractile cells in general. The articles composing this book have been selected and edited with the purpose of updating and reviewing the most important...
