Available in PDF, EPUB and Kindle. Book excerpt: De tout temps, l'homme a eu conscience de l'intérêt thérapeutique des toxines. Certaines toxines végétales depuis longtemps utilisées figurent encore dans la pharmacopée actuelle. Viennent s'y ajouter depuis peu des toxines microbiennes. Cependant le maniement des toxines natives ou à peine modifiées reste délicat tant est faible la marge entre les effets toxiques et l'efficacité thérapeutique. Comment, dans une perspective médicale, canaliser la puissance d'action et l'efficacité d'une toxine ? Connaître sa structure, comprendre son mécanisme d'action n'est pas suffisant : il faut aussi identifier sa cible privilégiée, autrement dit un récepteur cellulaire, faute de quoi l'entreprise apparemment chimérique d'un détournement de sa puissance et de sa spécificité reste aveugle. Ce cap est franchi, depuis un certain nombre d'années, et le développement des recherches sur les toxines axées sur la thérapeutique est devenu foisonnant. Voyez telle ou telle toxine protéique ternaire, avec ses trois domaines, de fixation sur un récepteur membranaire, de translocation qui lui permet de franchir la membrane cellulaire, et d'activité enzymatique qui va alors pouvoir s'exercer dans la cellule. Qu'on parvienne à dissocier chacun de ces trois domaines en leur conservant leurs propriétés, et des possibilités nouvelles d'utilisation thérapeutique vont s'ouvrir, presque à l'infini semble-t-il. Car chacun d'entre eux pourra être couplé à une molécule active bien ciblée, et leur efficacité sera même améliorée pour peu qu'on parvienne à conjuguer leur action. Qu'un récepteur, qu'une molécule, propres au métabolisme ou à la physiologie d'une cellule cancéreuse soient identifiés, et des toxines conjuguées à un ligand de ce récepteur, de cette molécule (ce peut être un anticorps) bloqueront les canaux ioniques ou exerceront leur effet cytolytique sur cette seule cellule, sans nuire aux cellules saines. Nous voilà dégagés de l'utopie, le contenu de cet ouvrage le prouve abondamment. Et même si la concrétisation des promesses reste délicate, le champ d'action est si vaste initialement qu'il ne saurait rester improductif : il ne l'est d'ailleurs déjà plus.
Download or read book Treatment of Bone and Soft Tissue Sarcomas written by Per-Ulf Tunn and published by Springer Science & Business Media. This book was released on 2008-12-28 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bone and soft tissue sarcomas represent only about 2% of all malignancies; however, their treatment – with the goal of curing the patient while preserving the functionality of the affected body part – can, unlike other malignancies, only be successful with therapy concepts devised by interdisciplinary teams. This volume provides an extensive up-to-date overview of the specific diagnostics and current treatment standards of these rare entities, presenting the various limb-sparing modalities for patients with bone and soft tissue sarcomas with special regard to innovative reconstructive options. The evaluation of quality of life based on validated scores and the individual methods of coping with the illness through creative artistic projects are also acknowledged and integrated in the whole concept.
Download or read book Toxins and Hemostasis written by R. Manjunatha Kini and published by Springer Science & Business Media. This book was released on 2010-10-19 with total page 790 pages. Available in PDF, EPUB and Kindle. Book excerpt: Circulation of blood is vital for the survival of vertebrates, including man. Mainly, it plays an important role in carrying food nutrients and oxygen to every tissue and organ and in removing all waste products and carbon dioxide. Any imbalance in the hemostatic and cardiovascular systems can lead to death and severe debility. A number of animals have developed mechanisms to target these systems and exploit the vulnerability. In some species (for example, snakes), such mechanisms are used to immobilize and kill the victim/prey, whereas in others (for example, insects, such as leaches, mosquitoes and ticks), they are used to provide a continuous supply of blood. These mechanisms include, but are not limited to, procoagulant and anticoagulant actions that affect the coagulation cascade and platelet aggregation, as well as altering vasodilatory responses. In all these various animals, these mechanisms have evolved to perfection over millions of years to support their survival. In last 3-4 decades, due to the efforts of scientists from various backgrounds including biology, protein chemistry, molecular biology, pharmacology, hematology, and structural biology, significant progress in understanding the structure-function relationships, as well as the mechanism of action have been made in a number of exogenous factors that affect blood coagulation, platelet aggregation and vasodilation from various animals. These exogenous factors have contributed significantly to the development of research tools as well as providing new therapeutic agents. With the increase average age of the population coupled with changes in life style in recent years, there has been a significant increase in cardiovascular and hematological disorders. Thus scientists in both academic institutions as well as the pharmaceutical industry are developing better therapeutic agents to improve the quality of life. This impetus has lead to the search for novel agents from various sources that interfere with cardiovascular and hematalogical processes. Although at first glance exogenous factors appear to function as ‘villains’, several life-saving drugs have been developed based upon these factors. Such drugs or drug leads include those that inhibit the angiotensin converting enzymes (Captopril and Enalapril), that block platelet receptors (Eptifibatide and Tirofiban), or that digest thrombotic plugs (Alfimeprase and bat plasminogen activator) to name a few. Several new and exciting success stories are currently unfolding. In this book, recent studies on some of the exogenous factors that play crucial roles in cardiovascular and hematological disorders are reviewed in order to consolidate the efforts in this area of research and to recruit new, talented researchers. The 25-30 review chapters, each written by experts in their field, compiled herein are devoted to exogenous factors affecting platelet aggregation, anticoagulant and procoagulant proteins, fibrinolytic proteins and hypotensive agents (For details see, Contents of the Book). This book is intended to help to create elevated awareness and enthusiasm in the field of exogenous factors. I believe that this book will provide greater impetus to the search for novel proteins based on naturally occurring exogenous factors. This will be the first book dealing extensively with exogenous factors in the last 25 years. The book will provide a ready reference to the different approaches used to solve complex problems in protein chemistry and pharmacology of exogenous factors. The book will update our understanding of the structure-function relationships and mechanisms of action of exogenous factors and provide great insights into future directions for solving the remaining challenges.

Available in PDF, EPUB and Kindle. Book excerpt: The occurrence of marine and freshwater toxins is a rapidly evolving problem due to ever-changing circumstances. Expanding international commerce is forcing cargo ships into virgin territory, deforestation and pollution violate the natural ecological balance, and a changing climate holds unknown potential to alter current factors and trigger toxic blooms in new forms, at new rates, and in new places. Fortunately, with notable advances in analysis technology, the body of knowledge in the field is equally dynamic. In just six years since the first edition, toxins that warranted only line listings, including pfiestra, gambierol, and polycavernoside, are now worthy of entire chapters, requiring a new edition to encompass the expanding scope of the field. Emphasizes Human Response to New Toxins Gathering contributions from international experts, Seafood and Freshwater Toxins: Pharmacology, Physiology, and Detection, Second Edition provides an overview of the current state-of-knowledge from several perspectives. Incorporating toxicology, chemistry, ecology, and economics, the book covers the biological aspects of the bloom and the effects and actions of each toxin with emphasis on human response. This edition includes more information on detection and analysis, toxicological information on previously little known toxins, and food safety issues. Incorporating Pharmacological, Legal, and Economic Aspects, this book— Begins with general information on risk assessment and analytical techniques Cover several categories of toxins by function and biomechanism Considers potential pharmacological applications and the use of toxins as precursors to therapeutic drugs Highlights the legal and economic perspectives of toxic incidence in industrial activity and international regulation and monitoring programs Describes new toxins by their individual chemical structure, ecobiology, metabolism, detection methods, determination, pharmacology, and toxicology

Book excerpt: Advances in Molecular Toxicology features the latest advances in all of the subspecialties of the broad area of molecular toxicology. Toxicology is the study of poisons, and this series details the study of the molecular basis by which a vast array of agents encountered in the human environment and produced by the human body itself manifest themselves as toxins. Not strictly limited to documenting these examples, the series is also concerned with the complex web of chemical and biological events that give rise to toxin-induced symptoms and disease. The new technologies that are being harnessed to analyze and understand these events will also be reviewed by leading workers in the field. Advances in Molecular Toxicology will report progress in all aspects of these rapidly evolving molecular aspects of toxicology with a view toward detailed elucidation of both progress on the molecular level and on advances in technological approaches employed. Cutting-edge reviews by leading workers in the discipline In-depth dissection of molecular aspects of interest to a broad range of scientists, physicians and any student in the allied disciplines Leading edge applications of technological innovations in chemistry, biochemistry and molecular medicine
