2 The role of Ca+ as an internal messenger in visual transduction of vertebrate and invertebrate organisms has been explored intensely in the recent past. Since the 2 early 1970s, calcium ions and cyclic GMP (whose levels are controlled by Ca+ in vertebrates) have been recognized as important second messengers. Particularly in 2 the last decade, however, the role of Ca+ in visual transduction has been re-evalu ated and a proliferation of research has documented a multiplicity of roles. 2 It is now evident that Ca+ modulates phototransduction by acting at several 2 sites through a host of...

Cell adhesion is one of the most important properties controlling embryonic development. Extremely precise cell-cell contacts are established according to the nature of adhesion molecules that are expressed on the cell surface. The identifica- tion of several families of adhesion molecules, well conserved throughout evolu- tion, has been the basis of a considerable amount of work over the past 20 years that contributed to establish functions of cell adhesion in almost all organs. Nowadays, cell adhesion molecules are not just considered as cellular glue but are thought to play critical roles...

World of Unstable Mutations The book "Triplet Repeat Diseases of the Nervous System" overviews the lat- est data on several disorders associated with unstable mutations. This field of re- search is progressing extremely fast. The number of polymorphic mutations and diseases caused by these mutations is increasing almost every month. There is a strong interest to molecular bases of triplet repeat disorders. This is explained by growing necessity to develop molecular approaches for cure of these diseases. There- fore, the authors of this book describe unstable mutations with the emphasis on...

Parkinson's disease, a degenerative brain disorder, affects an estimated 0.25-0.50% of the population. Symptoms result from neuronal degeneration in the nigrostriatal dopaminergic pathway and include tremor, rigidity and gradual slow- ness of spontaneous movement. The cause of Parkinson's disease is only partially understood; both environmental factors and a genetic predisposition have been im- plicated in its etiopathogenesis. Neural transplantation is being used experimentally for providing an alternative biological source of dopamine both in animal studies and in experimental clinical...

It is nearly a decade since the first Male Mediated Developmental Toxicity conference was held in Pittsburgh. The continuing public/scientific interest, growing amounts of animal data, introduction of innovative technologies, and increasing quantity of human epidemiological studies all suggest that male-mediated developmental toxicity is of major concern. A number of researchers concluded that a Second International Confer ence on Male Mediated Developmental Toxicity was necessary. The ensuing volume is particularly timely because it impacts on areas of special emphasis in many countries,...

Immune Mechanisms of Pain and Analgesia is the first volume to discuss a new concept of immune-neural interplays leading to pain or analgesia. It argues the classical view that pain and its control are restricted to the nervous system, offering a comprehensive overview of the emerging area of immune mechanisms in pain and its control. It challenges the traditional view that pain sensation or suppression is attributed exclusively to the nervous system and presents a critical analysis of this new concept. The book is written by an internationally recognized group of researchers...

This volume is ideal for individuals interested in taking an in-depth look at how cytokines and chemokines participate in autoimmune disorders, and how cytokines and chemokines can be used as targets for therapeutic intervention. The outstanding features of this book are that it is divided in chapters each focusing on specific, highly prevalent autoimmune disorders. The role of cytokines and chemokines in each of these disorders is dissected in the context of the autoinimune responses that drive these diseases. Importantly, each chapter is meant to provide an in-depth review of how cytokines...

New experimental observations often require fresh concepts for their interpretation, and at times even changes of paradigms. This is the situation with the recent realization that circulating endothelial progenitor cells may have an important contribution to the maintenance and formation of new endothelium in adult organisms, in a surprisingly wide variety of situations. The classical paradigm of angiogenesis, centered on the notion of "sprouting" can hardly accommodate them. It was previously realized that it needs to be "stretched out" to include alternative mechanisms of microvascular...

Since its launch in 1998 the European Society for Intravenous Anaesthesia (EuroSIVA) has come a long way in providing educational material and supporting the research and clinical application of intravenous anaesthesia. After the first two annual meetings held in Barcelona and Amsterdam in 1998 and 1999, three other successful meetings took place in Vienna, Gothenburg and Nice in 2000, 2001 and 2002. Next to these main meetings, starting in the year 2000, a smaller winter meeting has been organised every last week of January in Crans Montana, Switzerland. Both the main summer and the winter...

Proceedings of the International Conference on Dipeptidyl Aminopeptidases, held September 26-28, 2002, in Berlin, Germany.

Dipeptidyl Aminopeptidases exert a potent modulatory role at an interface between immune mechanisms, metabolic responses and neuroendocrine pathways. Experimental models and clinical studies addressing the role of these enzymes and the effect of specific inhibitors pave the way to novel therapeutic concepts in immunology, rheumatology, oncology, reproductive medicine and diabetes.

Leading experts in this field have contributed to this book which...
