Book excerpt: Although the anticholinesterase (anti-ChE) agents have only limited applica tions in therapy, and from the viewpoint of practical significance they are more appropriately classified as toxic compounds or insecticides than as drugs, in their capacity of pharmacological tools they have few equals. The concept of neuro humoral transmission was originally established largely from experiments in which physostigmine, or eserine, was employed to protect acetylcholine (ACh), the trans mitter of the cholinergic nerves, from rapid hydrolytic destruction by acetyl cholinesterase (AChE) and other cholinesterases (ChE's). Since then, a great num ber of additional reversible and irreversible anti-ChE agents also have been indis pensable in studies of synaptic and neuroeffector transmission, and of other physiological processes. At the same time, there is practically no other class of compounds for which a mechanism of pharmacological action can be described in such concrete biochemical and physiological terms. Consequently, it is not sur prising that a huge literature has developed on these several closely interdependent topics. The assembling anrl proper correlation of this material for the present volume has taken the collaborative efforts of over two dozen . investigators. It iR believed that their contributions to this end will prove invaluable to future in vestigators in providing a ready, inclusive source of established information, in defining areas where further studies are indicated, and in preventing unnecessary duplication of past work. How well these aims have been accomplished will be for time and the reader to judge.

Book excerpt: Modern Trends in Physiological Sciences, Volume 3: Cholinesterases: A Histochemical Contribution to the Solution of Some Functional Problems covers the histochemical aspects of humoral and tissue cholinesterases, both inside and outside of the nervous system. This volume is composed of three part encompassing 14 chapters. The first part describes the link between cholinesterases and serum and between acetylcholinesterase and erythrocytes. This part also deals with the histochemical measurement of acetylcholinesterase activity in the erythrocytes or platelets of some mammalian species, with an emphasis on delineating the possible role of this enzyme in maintaining the integrity of these cells. The remaining two parts discuss the convergence of morphological, physiological, and biochemical research on tissue cholinesterases. These parts also describe the general features of the localization of cholinesterases at nerve-endings in tissues and organs. Histochemical investigations of tissular cholinesterases outside the nervous system, such as in smooth muscle fibers, are also presented. This book will be of value to physiologists, enzyme scientists and researchers, cell biologists, and histochemists.

Available in PDF, EPUB and Kindle. Book excerpt: Acetylcholinesterase (AChE) is a primary regulator of cholinergic signaling within and out of the central nervous system. It has been studied extensively for several decades, yet many basic questions about its regulation, composition and functions remain open. Thus, neither the full impact of AChE’s activities on neuronal development, maintenance and functioning nor the reasons for why and how different AChE molecular forms are being synthesized and degraded are fully known yet, although recent evidence suggests the involvement of micro-RNA regulators in both of these aspects. The identification of the anchoring proteins, PRiMA and ColQ, stimulates studies on AChE’s assembly and its specific localization in the brain and muscle. Additionally, non-cholinergic function(s) of AChE has been proposed as relevant both for neuronal differentiation and cognitive functioning, whereas transgenic engineering, recombinant production and structure-function analyses of this enzyme’s variants with various inhibitors paved new avenues for the development of novel Alzheimer’s disease therapeutics, agricultural pesticides and prophylactics in anticipation of warfare agent exposure. The aims of this Research Topic is to provide a forum for experts in the field to critically discuss recent developments in AChE studies, initiate global critiques of the current views for resolving the fundamental questions in AChE research and promote the development of novel versions and uses of AChE-targeted agents. Topics of interest include but are not limited to: (i) post-transcriptional regulation of AChE; (ii) the non-cholinergic functions of AChE; and (iii) anti-AChE inhibitors and diseases.

This book was released on 2013-11-27 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sixth International Meeting on Cholinesterases and Related Proteins, Choli nesterases '98, was organized by Palmer Taylor and his associates at the University of California-San Diego and convened in La Jolla, California, USA, in March of 1998. This was the first conference of the series to be held in the United States, let alone on the Pa cific Rim. Nearly 200 delegates from twenty countries-from Asia, Australia, Europe, and North and South America-heard 75 oral presentations and viewed 90 posters on current research on cholinesterases and related proteins. The meeting framework was structured to include two days of plenary sessions, followed by two days of concurrent sessions and workshops in specific areas. Communication at the concurrent sessions was facilitated by the conference settings of the Martin Johnson House, on a scenic bluff overlooking the blue Pacific Ocean, and the San Diego Supercomputer Center, which enabled projection and rotation of protein structures in three dimensions for a large audience. This book is the compilation of the presentations at the Sixth International Meeting on Cholinesterases and Related Proteins into a volume that describes recent investigations on the structure, catalytic and non-catalytic functions of acetylcholinesterase (AChE), butyrylcholinesterase (BuChE), and related proteins, as well as studies on the molecular and cellular biology of these enzymes and the genes that encode them.

Available in PDF, EPUB and Kindle. Book excerpt: This text/reference book provides the most comprehensive coverage of anticholinesterase compounds (Organophosphates and Carbamates), which constitute the largest number of chemicals that are primarily used as insecticides in agriculture, industry, and around the home/garden. Some OPs (nerve agents) have been used in chemical warfare and terrorist attacks, while some OPs and CMs have been recommended as therapeutic agents in human medicine as well as in veterinary medicine. Many chemicals of both classes are extremely toxic and lack selectivity, thus their inadvertent/accidental use continues to pose a threat to human and animal health, aquatic systems and wildlife. These anticholinesterase agents produce a variety of toxicological effects in target and nontarget organs. In light of this complexicity, this multi-authored book is written by the well known scientists from many countries. The book is organized into nine sections, with a total of 49 chapters, to provide in-depth knowledge on various aspects of OP and CM compounds, including their use, classification, mechanism-based toxicity, and prophylactic and therapeutic measurements. Several chapters are written with special emphasis to cover timely topics, such as chemical warfare agents, physiologically-based pharmacokinetic modeling, structure and function of cholinesterases, paraoxonase, carboxylesterases; developmental neurotoxicity, the intermediate syndrome, oxidative stress, endocrine disruption, and DNA damage/gene expression and carcinogenesis. Section-VI with 5 chapters is specifically devoted to risk assessment, and safety and regulatory guidelines for pesticides. - Describes everything you need to know about Organophosphates and Carbamates - Extensively covers pesticides, nerve agents, therapeutic drugs, and flame retardants - Describes epidemiology of the world's major disasters involving Organophosphates and Carbamates - Covers animal, human, aquatic, and wildlife toxicity of Anticholinesterases - Insights into in-depth cholinergic and noncholinergic mechanisms of toxicity - Describes recent advancements in cholinesterases, paraoxonases, carboxylesterases, oxidative stress, endocrine disruption, cardiac and pulmonary toxicity, and carcinogenesis - Provides in vitro and in vivo models for neurotoxicity testing - Integrates knowledge of studies in lab animals and humans - Offers risk/safety assessment and national/international guidelines for permissible levels of pesticide residues - Describes management of Anticholinesterase poisoning in humans

Book excerpt: Two types of cholinesterases (ChEs) are found in the mammalian brain: acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). They are products of two different genes and exhibit different localizations and kinetic properties. Until recently, the function of BuChE and its role in the regulation of acetylcholine levels in the central nervous system have been largely unknown. There is now evidence that BuChE plays a vital role in the brain cholinergic system, and that it may have a key role in the development of Alzheimer's disease. Butyrylcholinesterase: Its Function and Inhibitors is for neurologists, psychiatrists, geriatricians and neuroscientists who want a full profile of BuChE.

Book excerpt: The Fifth International Meeting on Cholinesterases convened in Madras, India, in September of 1994. The long and rich history and culture of India provided an excellent setting for the meeting. More than 120 delegates from Asia, Australia, Europe and North America heard 54 oral presentations and viewed 54 posters on current research on enzymes of the cholinesterase family. The aim of this book is to compile the presentations of the Fifth International Meeting on Cholinesterases into a volume that describes recent investigations on the structure and catalytic function of acetylcholinesterase (AChE), butyrylcholinesterase (BuChE) and related enzymes, as well as studies on the molecular and cellular biology of these enzymes and the genes which encode them. Cholinesterases enjoy a long and storied history in diverse areas. In basic biochemical research, AChE is one of the best studied, though yet enigmatic, of enzymes. The efficient catalytic function of this enzyme presents the biochemist with a fundamental challenge in understanding the relationship between structure and function. AChE and BuChE belong to a family of proteins, the alB hydrolase fold family, whose constituents evolutionarily diverged from a common ancestor. Proteins in this family have a wide range of physiological functions. In commerce, AChE is a prime target for agricultural insect control, and for the development of therapeutic agents for Alzheimer's disease.

Available in PDF, EPUB and Kindle. Book excerpt: The development of resistance to pesticides is generally acknowledged as one of the most serious obstacles to effective pest control today. Since house flies first developed resistance to DDT in 1946, more than 428 species of arthropods, at least 91 species of plant pathogens, five species of noxious weeds and two species of nematodes were reported to have developed strains resistant to on~ or more pesticides. A seminar of U. S. and Japanese scientists was held in Palm Springs, California, during December 3-7, 1979, under the U. S. -Japan Cooperative Science Program, in order to evaluate the status of research on resistance and to discuss directions for future emphasis. A total of 32 papers were presented under three principal topics: Origins and Dynamics of Resistance (6), Mechanisms of Resistance (18), and Suppression and Management of Resistance (8). The seminar was unique in that it brought together for the first time researchers from the disciplines of entomology, plant pathology and weed science for a comprehensive discussion of this common problem. Significant advances have been identified in (a) the development of methods for detection and monitoring of resistance in arthropods (electrophoresis, diagnostic dosage tests) and plant pathogens, (b) research on biochemical and physiological mechanisms of resis tance (cytochrome p450, sensitivity of target site, gene regulation), (c) the identification and quantification of biotic, genetic and operational factors influencing the evolution of resistance, and (d) the exploration of pest management approaches incorporating resis tance-delaying measures.

Available in PDF, EPUB and Kindle. Book excerpt: The peripheral nervous system is usually defined as the cranial nerves, spinal nerves, and peripheral ganglia which lie outside the brain and spinal cord. To describe the structure and function of this system in one book may have been possible last century. Today, only a judicious selection is possible. It may be fairly claimed that the title of this book is not misleading, for in keeping the text within bounds only accounts of olfaction, vision, audition, and vestibular function have been omitted, and as popularly understood these topics fall into the category of special senses. This book contains a comprehensive treatment of the structure and function of peripheral nerves (including axoplasmic flow and trophic func tions); junctional regions in the autonomic and somatic divisions of the peripheral nervous system; receptors in skin, tongue, and deeper tissues; and the integrative role of ganglia. It is thus a handbook of the peripheral nervous system as it is usually understood for teaching purposes. The convenience of having this material inside one set of covers is already proven, for my colleagues were borrowing parts of the text even while the book was in manuscript. It is my belief that lecturers will find here the information they need, while graduate students will be able to get a sound yet easily read account of results of research in their area. JOHN 1.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years our understanding of molecular mechanisms of drug action and interindividual variability in drug response has grown enormously. Meanwhile, the practice of anesthesiology has expanded to the preoperative environment and numerous locations outside the OR. Anesthetic Pharmacology: Basic Principles and Clinical Practice, 2nd edition, is an outstanding therapeutic resource in anesthesia and critical care: Section 1 introduces the principles of drug action, Section 2 presents the molecular, cellular and integrated physiology of the target organ/functional system and Section 3 reviews the pharmacology and toxicology of anesthetic drugs. The new Section 4, Therapeutics of Clinical Practice, provides integrated and comparative pharmacology and the practical application of drugs in daily clinical practice. Edited by three highly acclaimed academic anesthetic pharmacologists, with contributions from an international team of experts, and illustrated in full colour, this is a sophisticated, user-friendly resource for all practitioners providing care in the perioperative period.
