Book Description
Venom research and technology has advanced greatly, rapidly transforming our knowledge of reptile venoms. Research advances, like the development of molecular systematics, provide the framework necessary to reconstruct the evolutionary history of glands and fangs. Such research developments have expanded our understanding of venom's evolution and its usefulness in therapeutic development. The results of this punctuated toxin molecular evolutionary expansion include protein neofunctionalization. While these changes may impact antivenom efficacy, this molecular diversity also facilitates their usefulness in the development of novel drug therapies. Venomous Reptiles And Their Toxins brings together the world's leading toxinologists in this comprehensive study of the entire scope of reptile venoms, from clinical effects to evolution to drug design and development. The book contains detailed applied chapters on clinical care of the envenomed patient, ineffective traditional or modern remedies, occupational considerations involved in the maintenance of institutional venomous reptile collections, veterinary care for venomous reptiles and research methods used in venom research. This book also devotes a chapter to each toxin class found in reptile venoms, detailing the full trajectory of research on the peptide or protein in question. These chapters discuss each toxin's respective role in the envenomation process through to how each has been explored for their biomedical potential. This book is a unique resource for anyone working with venomous reptiles.

ISBN: 1588344541
Category : Nature
Languages : en
Pages : 207

Book Description
Venom brings readers face to face with some of the most dangerous creatures on the planet, including jellyfish, snakes, and wasps, as it uncovers the story of venom. The book explores how venom is used for predation, defense, competition, and communication by an incredible diversity of species. It examines the unique methods that these species have evolved to create and deliver their deadly toxins. The book traces venom back to its origin in early jellyfish and sea anemones, and reveals how venoms have evolved dozens of times independently all across the animal kingdom since that time. And finally, it examines the relationships between these dangerous creatures and humans. Humans have not only learned to live with them, but also to benefit from them: scientists increasingly are harnessing the power of venom to create new drugs, treatments, and anti-venoms.

Book Description
A thrilling tale of encounters with nature’s masters of biochemistry From the coasts of Indonesia to the rainforests of Peru, venomous animals are everywhere—and often lurking out of sight. Humans have feared them for centuries, long considering them the assassins and pariahs of the natural world. Now, in Venomous, the biologist Christie Wilcox investigates and illuminates the animals of our nightmares, arguing that they hold the keys to a deeper understanding of evolution, adaptation, and immunity. She reveals just how venoms function and what they do to the human body. With Wilcox as our guide, we encounter a jellyfish with tentacles covered in stinging cells that can kill humans in minutes; a two-inch caterpillar with toxic bristles that trigger hemorrhaging; and a stunning blue-ringed octopus capable of inducing total paralysis. How do these animals go about their deadly work? How did they develop such intricate, potent toxins? Wilcox takes us around the world and down to the cellular level to find out. Throughout her journey, Wilcox meets the intrepid scientists who risk their lives studying these lethal beasts, as well as “self-immunizers” who deliberately expose themselves to snakebites. Along the way, she puts her own life on the line, narrowly avoiding being envenomated herself. Drawing on her own research, Wilcox explains how venom scientists are untangling the mechanisms of some of our most devastating diseases, and reports on pharmacologists who are already exploiting venoms to produce lifesaving drugs. We discover that venomous creatures are in fact keystone species that play crucial roles in their ecosystems and ours—and for this alone, they ought to be protected and appreciated. Thrilling and surprising at every turn, Venomous will change everything you thought you knew about the planet’s most dangerous animals.

Pages : 548

Book Description
Molecular Toxinology has been consolidated as a scientific area focused on the intertwined description of several aspects of animal toxins. In an inquiring biotechnological world, animal toxins appear as an invaluable source for the discovery of therapeutic polypeptides. Animal toxins rely on specific chemical interactions with their partner molecule to exert their biological actions. The comprehension of how molecules interact and recognize their target is essential for the rational exploration of bioactive polypeptides as therapeutics. Investigation on the mechanism of molecular interaction and recognition offers a window of opportunity for the pharmaceutical industry and clinical medicine. Thus, this book brings examples of two interconnected themes - molecular recognition and toxinology concerning to the integration between analytical procedures and biomedical applications.

Handbook of Venoms and Toxins of Reptiles

Handbook of Venoms and Toxins of Reptiles PDF Author: Stephen P. Mackessy
Publisher: CRC Press
ISBN: 0429623453
Category : Nature
Languages : en
Pages : 912

Book Description
A decade after publication of the first edition, Handbook of Venoms and Toxins of Reptiles responds to extensive changes in the field of toxinology to endure as the most comprehensive review of reptile venoms on the market. The six sections of this new edition, which has nearly doubled in size, complement the original handbook by presenting current information from many of the leading researchers and physicians in toxinology, with topics ranging from functional morphology, evolution and ecology to crystallography, -omics technologies, drug discovery and more. With the recent recognition by the World Health Organization of snakebite as a neglected tropical disease, the section on snakebite has been expanded and includes several chapters dealing with the problem broadly and with new technologies and the promises these new approaches may hold to counter the deleterious effects of envenomation. This greatly expanded handbook offers a unique resource for biologists, biochemists, toxicologists, physicians, clinicians, and epidemiologists, as well as informed laypersons interested in the biology of venomous reptiles, the biochemistry and molecular biology of venoms, and the effects and treatment of human envenomation.

Spider Venoms

Spider Venoms PDF Author: P. Gopalakrishnakone
Publisher: Springer
ISBN: 9789400763883
Category : Medical
Languages : en
Pages : 0

Book Description
In recent years, the field of Toxinology has expanded substantially. On the one hand it studies venomous animals, plants and micro organisms in detail to understand their mode of action on targets. While on the other, it explores the biochemical composition, genomics and proteomics of toxins and venoms to understand their three interaction with life forms (especially humans), development of antidotes and exploring their pharmacological potential. Therefore, Toxinology has deep linkages with biochemistry, molecular biology, anatomy and pharmacology. In addition, there is a fast developing applied subfield, clinical toxinology, which deals with understanding and managing medical effects of toxins on human body. Given the huge impact of toxin-based deaths globally, and the potential of venom in generation of drugs for so-far incurable diseases (for example, Diabetes, Chronic Pain), the continued research and growth of the field is imminent. This has led to the growth of research in the area and the consequent scholarly output by way of publications in journals and books. Despite this ever growing body of literature within biomedical sciences, there is still no all-inclusive reference work available that collects all of the important biochemical, biomedical and clinical insights relating to Toxinology. The Handbook of Toxinology aims to address this gap and cover the field of Toxinology comprehensively.

Arthropod Venom Components and Their Potential Usage

Arthropod Venom Components and Their Potential Usage PDF Author: Katsuhiro Konno
Publisher: MDPI
ISBN: 3039285408
Category : Medical
Languages : en
Pages : 404

Book Description
Thousands of arthropod species, ranging from arachnids (spiders and scorpions) to hymenopterans (ants, bees, and wasps) and myriapods (centipedes), are venomous and use their venoms for both defense and predation. These venoms are invariably harmful to humans, and some may cause serious injuries, e.g., those from scorpions, spiders, and wasps. Arthropods’ venoms are also known as rich sources of biologically active compounds and have attracted the attention of toxin researchers for years. In this century, venom component analysis has progressed considerable due to the advances in analytical techniques, in particular, mass spectrometry and next-generation deep (DNA and RNA) sequencing. As such, proteomic and peptidomic analyses using LC–MS have enabled the full analysis of venom components, revealing a variety of novel peptide and protein toxins sequences and scaffolds, potentially useful as pharmacological research tools and for the development of highly selective peptide ligands and therapeutic leads, like chlorotoxin. Due to their specificity for numerous ion-channel subtypes, including voltage- and ligand-gated ion channels, arthropod neurotoxins have been investigated to dissect and treat neurodegenerative diseases and control epileptic syndromes. This Special Issue collects information on such progress, encouraging contributions on the chemical and biological characterization of venom components, not only peptides and proteins, but also small molecules, their mechanisms of action, and the development of venom-derived peptide leads.

"Venomous" Bites from "Non-Venomous" Snakes

Author: Scott A Weinstein
Publisher: Elsevier
ISBN: 0128227877
Category : Medical
Languages : en
Pages : 790

Book Description
"Venomous" Bites from "Non-Venomous" Snakes, Second Edition thoroughly examines the potential hazards associated with bites by non-front-fanged snakes (popularly, but inaccurately, called "rear-fanged snakes"). This diverse group contains approximately 80% of living snake species (approximately 2,900 species). A large proportion of these snakes were previously assigned to the family Colubridae but, as a consequence of expanding systematics investigations, have been split into multiple families and subfamilies. Many of these snakes produce venoms or oral secretions that contain toxins and other biologically active substances. A large variety of non–front-fanged snakes figure in the pet industry, yet little documented information or formal study of their potential medical importance has been published. Therefore, although the possible medical importance of many of these species has been subjected to speculation since the mid-19th century, there is a limited amount of useful descriptive information regarding the real hazard (or lack thereof) of this wide variety of snakes. The first edition of this book provided "one-stop shopping" by offering information regarding their possible toxicity and clinical relevance as well as recommendations for medical management of their bites. The second edition expands and updates the content with detailed information about the effects and medical management of bites by a broad representation of non–front-fanged species. The hypothetical venomous nature of some lizards considered as non-venomous such as the Komodo monitor or dragon and their allies, as well as the medical effects of their bites, is also examined. The dynamic taxonomy of advanced snakes is updated, and the bases for some of these fluid changes are discussed. Likewise, terminology is also updated in order to reflect the ongoing debates regarding the definition of "venom" and the balanced reinforcement of nonmedical criteria used to define the biological basis of the term "venomous." - Fills a gap in toxicological, medical, and herpetological literature by providing a comprehensive review of this entire assemblage of non–front-fanged snakes, with particular attention given to their capacity to cause harm to humans - Offers a patient-centered, evidence-based approach which is applied to analyzing documented case reports of bites inflicted by a broad representation of species - Provides expanded and updated detailed information on the clinical management of medically significant bites from non–front-fanged snakes, which is also methodically reviewed, and specific recommendations are provided - Includes updates of the fluid taxonomy of advanced snakes and also of terminology with particular regard to the definition of "venom" and the nonmedical criteria used to define the biological basis of the "venomous condition" in snakes and lizards
