As early as in the twenties and thirties of our century Ernst Scharrer published papers suggesting, on the basis of morphological findings, that the brain exhibits secretory function which he called neurosecretion. Only a few decades later Scharrer's presumption was fully confirmed by the isolation of a number of neuropeptides and by the disclosure of their chemical stuctures. Neuropeptide research is one of the most rapidly expanding fields in biomedicin. Initially investigators focused their attention on the existence and role of neuropeptides within the hypothalamo-hypophyseal system. This...

Neuropeptides rank among the phylogenetically oldest interneuronal signal substances. In the concept of neuro-secretion they were identified as neurohormones by which - via the blood - the brain regulates peripheral functions. It is now evident that the neuropeptides act as neurotransmitters/-modulators, as (neuro-)hormones, and paracrine or autocrine signal substances in diverse parts of the body. This book reviews, in several comprehensive articles written by distinguished specialists, the state of the art in the field of neuropeptides and peptidergic neurons. Special topics concern...

Two events have recently improved the prospects of protecting fish and their environment in Switzerland: the acceptance of a new Federal Water Protection Law in the plebiscite of May 17th 1992, and the new Federal Legislation on Fisheries, in force since January 1st 1994. With this legal framework, the possibilities for protection of nature and landscape have now considerably improved in Switzerland. The most important aims of the Federal Law on Water Protection are to safeguard the natural habitats of the native flora and fauna and water as the habitat of aquatic organisms. This includes not...

The field of neuroscience is experiencing a period of unprecedented growth. The range of ap proaches used to investigate the fundamental mechanisms underlying different aspects of somatosen sory perception has expanded substantially since the last International Symposium on Informa tion Processing in the Somatosensory System. Diversity of approach has become the hallmark of somatosensory research, and I believe that the impact of this diversity continues to be positive. of this symposium with previous symposia will show that researchers are employing Comparison an array of new methods and...

In 1992, a group of scientists including molecular biologists, microbiologists, population biolo gists, ecologists, human geneticists, moral philosophers and others met discussing the state of affairs regarding the deliberate or unintentional release of genetically modified organisms. The proceedings of this meeting were subsequently published by Birkhauser Verlag as Transgenic Organisms: Risk Assessment of Deliberate Release (K. Wohrmann and J. Tomiuk). Since then we have gained many new insights that are also worthy of discussion. And although other equally important scientific views on the...

At present, we do not fully understand at what stage of the evolution of living matter the first traces of defense reactions occurred. We even do not fully understand how and why immune systems reached their contem porary state in advanced vertebrates and man. It may be expected that in the near future these questions will be answered by comparative and develop mental biology. Together with an extraordinary explosion of our knowledge about immunity of mammals including man, an increase in the interests concerning origin and development of immune mechanisms at lower stages of the phylogeny can...

About 80 scientists from allover the world have gathered at the Parc Valrose Scientific Campus of Nice -Sophia Antipolis University, for the 5th UNESCO International Conference on "Water and Ions in Biornolecular Systems", to present and discuss current problems in the field. The Conference proceedings comprise selected and reviewed contributions of invited plenary lectures, lectures and posters presentations which cover all the Biophysical sectors of research on the following three major topics : * Water, Ions and Nucleic Acids * Water, Ions and Membranes * Water, Ions and Proteins The...

In evolutionary time scales natural disturbances have affected the vegetation on Earth. During the Quaternary the forest biomes of the tropics were subjected to manifold disturbances. Climate changes and climate oscillations were associated with changing precipitation and drought regimes, flooding, siltation, landslides, etc. The prehistorical forest was also influenced by the effects of large wildlife populations. Large-scale catastrophies in the forest biomes were mainly caused by abiotic environmental alterations, the small-scale disturbances were and still are related to both biotic and...
