This book represents the proceedings from a conference that took place in Dallas in the spring of 1999 which was entitled "Pediatric Gender Assignment - A Critical Reappraisal". Some participants rightfully argued that the conference really focused on the issue of pediatric gender assignment, and that reassignment was not applied in most cases. Their comments were reflected in the title of this monograph. This multidisciplinary meeting was sponsored by a conference grant from the National Institutes of Health, and a broad inquiry into this complex topic took place from many points of view. Basic scientists offered insight into mechanisms of sexual differentiation of the gonads, physical phen...
This volume foxuses on the status of Ca2+ ions in regulation of phototransduction, light adaptation and the recovery phase in vertebrate photoreceptors. Particular emphasis is given to Ca2+-binding proteins and their targets, among them particulate guanylate cyclases, GPCR-coupled kinases and cyclic nucleotide-gated cation channels. The book also expands our understanding of events invovling Ca2+ in the retinal pigment epithelium, in synaptic transmission and secondary retinal neurons. A significant part of the book is dedicated to the role of Ca2+ in invertebrate phototransduction, the best-studied phospholipid-mediated signal transduction pathway. Several chapters explore association of gene defects with human retina disease and the generation of animal models of retinal degeneration.
Given the very limited capacity of regeneration in the brain, protecting neurons that are on the brink of death is a major challenge for basic and clinical neuroscience, with implications for a broad spectrum of acute and chronic neurological and psychiatric diseases. This book brings together leading experts from neurobiology, neurophysiology, neuropharmacology, neuroimmunology and clinical neuroscience to highlight the most recent milestones in this rapidly evolving field. The book will serve as a reference for both basic neuroscientists and clinicians interested in an authoritative update on the molecular and cellular biology of neuroprotection and its promises for new therapeutic strategies.
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 and discusses complex and controversial issues such as cytokines and their pain-exacerbating but also analgesic effects, the production of opioids by immune cells, peripheral analgesic and anti-inflammatory actions of opioids, immunomodulatory effects of opiates, and immunosuppressive effects of pain.
The ISOTT 2001 local organizing committee was pleased to welcome over 140 delegates from around the world to the 29th annual general meeting of the International Society for Oxygen Transport to Tissue. The meeting was held in historic Philadelphia, USA, on the campus of the University of Pennsylvania from August 11 to 15, 2001. In the tradition of ISOTT, the conference was a total immersion experience. Attendees were encouraged to eat together and spend their evenings relaxing together in a style that maximized exchange of ideas and interactions of younger scientists with their more senior colleagues. Delegates participated in a total of 122 presentations including poster displays, selected ...
This volume represents a collection of contributions from the 6th International Conference on Eicosanoids and Other Bioactive Lipids in Cancer, Inflammation, and Related Diseases held in Boston from September 12-15, 1999. The mission of this meeting was to bring together senior and junior investigators to both announce and examine their recent advancements in cutting-edge research on the roles and actions of lipid mediators and their impact in human physiology and disease pathogenesis. The meeting focused on new concepts in these areas of interest to both clinicians and researchers. The program included several outstanding plenary lectures and presentations by leading experts in the fields o...
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 in cell signaling. Their ability to influence cell proliferation, mi gration, or differentiation depend...
This book is the culmination of fifteen years of research on the transplantation of dopaminergic neurons in the striatum of the weaver mouse (wv/wv), a neurological mutant characterized by genetically-determined degeneration of midbrain dopamine neurons. This mutant constitutes the only available laboratory model with a chronic disorder that mimics Parkinson's disease. Structural and functional aspects of intrastriatal mesencephalic neuron grafting into the weaver model are reviewed, including histochemical correlates of graft survival and integration, numerical aspects of donor cell survival, ultrastructural findings on synaptogenesis, neurochemical indices of dopamine uptake and receptor binding, gene expression of structural and neurotransmitter-receptor related molecules, levels of striatal amino acid receptors, and behavioural effects of unilateral and bilateral neuronal transplantations.
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 molecular pathology. Broad discussion is presented on how polymorphic expan sions cause cell dysfunction. o...
