Book Description
The discovery of new molecules that function in neuronal communication can be viewed as a progression of steps beginning with the identification of the molecular structure, moving to the understanding of the mecha nisms mediating the synaptic action, and to the appraisal of the involve ment of the new molecules in various neuronal mechanisms, and finally reaching the evaluation of this molecule's role in brain function and the consequences that are triggered by its abnormalities. Enkephalins have followed such a pattern, and the present publication expresses the salient points of the last two phases in this succession. Enkephalins were discovered in December 1975; in addition to pain threshold regulation, their participation in other brain functions was soon ascertained. Perhaps, there are multiple recognition sites for multiple molecular forms of endogenous enkephalins; similarly to other transmitter recognition sites, these are coupled with ionic and nucleotide amplifying systems; thus, when activated, they can modify membrane funtion and ionic permeability of membranes. The present publication probes the current status of our knowledge concerning the consequences related to abnormalities in enkephalin storage, release, and synthesis. However, since our basic understanding of enkephalins is incomplete, the views reported should be considered to be in a state of flux.

Book Description
Drug overdose, driven largely by overdose related to the use of opioids, is now the leading cause of unintentional injury death in the United States. The ongoing opioid crisis lies at the intersection of two public health challenges: reducing the burden of suffering from pain and containing the rising toll of the harms that can arise from the use of opioid medications. Chronic pain and opioid use disorder both represent complex human conditions affecting millions of Americans and causing untold disability and loss of function. In the context of the growing opioid problem, the U.S. Food and Drug Administration (FDA) launched an Opioids Action Plan in early 2016. As part of this plan, the FDA asked the National Academies of Sciences, Engineering, and Medicine to convene a committee to update the state of the science on pain research, care, and education and to identify actions the FDA and others can take to respond to the opioid epidemic, with a particular focus on informing FDA's development of a formal method for incorporating individual and societal considerations into its risk-benefit framework for opioid approval and monitoring.

Book Description
A remarkable collaboration between psychologist Rossi and gynecologist-obstetrician Cheek, this book guides and empowers therapists and patients to find the keys to their own health and well-being through therapeutic hypnosis. Hundreds of engaging case reports from Cheek's forty years of clinical work bring the theory of mind-body therapy to life, while Rossi's chapters link Cheek's often intuitive work to the latest research in psychobiology.

Book Description
Scientists have speculated as to the nature of cerebrospinal fluid (CSF) - "the third circulation" or "vital spirit" for centuries. Just what is this mysterious bathing solution of the central nervous system? Is it a vehicle of transport for an "animal spirit" directing all our activities, as thought by Galen (Singer, 1956) or but a "modified tap water" (Halliburton, 1917)? With the advent of lumbar puncture, cerebrospinal fluid has become a readily available and important means of studying disease affecting the nervous system. In recent years, many sophisticated tools including com puter guided gas chromatography/mass spectrometry and high performance liquid chromatography have made it possible to identify and quantify many constituents of this fluid. The CSF has an enormous, though largely "untapped", potential in aiding diagnosis and evaluating treatment of many neurological, psychiatric and systemic disorders. As the ependyma is only a diffusional barrier between the CSF and extracellular fluid of the brain for many compounds, changes in the concentration of these compounds in the CSF may reflect disease processes in the brain.

Book Description
Hormonal Proteins and Peptides: ß-Endorphin, Volume X focuses on the chemistry, biology, and clinical investigations of opioid peptides. This book discusses the chemical approach in isolating a chemical entity from its natural source and investigates its biological activity after it has been determined to be a pure substance. Organized into nine chapters, this volume starts with an overview of the structure–activity relationship of ß-endorphin (ß-EP) by synthetic approach. This text then explores the proteinases involved in the generation of opioid peptides, including ß-EP from ß-lipotropin (ß-LPH). Other chapters review the biosynthesis of ß-EP and consider in detail the opiate receptor. This book discusses as well the anatomy of ß-EP-containing structures in pituitary and brain. The final chapter presents a discussion on the historical aspects of opiate–peptide discoveries, particularly in the field of narcotic antagonists. This book is a valuable resource for chemists, biologists, endocrinologists, physicians, and neurobiologists.

Book Description
The opioid crisis in the United States has come about because of excessive use of these drugs for both legal and illicit purposes and unprecedented levels of consequent opioid use disorder (OUD). More than 2 million people in the United States are estimated to have OUD, which is caused by prolonged use of prescription opioids, heroin, or other illicit opioids. OUD is a life-threatening condition associated with a 20-fold greater risk of early death due to overdose, infectious diseases, trauma, and suicide. Mortality related to OUD continues to escalate as this public health crisis gathers momentum across the country, with opioid overdoses killing more than 47,000 people in 2017 in the United States. Efforts to date have made no real headway in stemming this crisis, in large part because tools that already existâ€"like evidence-based medicationsâ€"are not being deployed to maximum impact. To support the dissemination of accurate patient-focused information about treatments for addiction, and to help provide scientific solutions to the current opioid crisis, this report studies the evidence base on medication assisted treatment (MAT) for OUD. It examines available evidence on the range of parameters and circumstances in which MAT can be effectively delivered and identifies additional research needed.

Book Description
First published in 1986, Controversies in Alcoholism and Substance Abuse presents a collection of papers dealing with various aspects of alcohol and substance abuse. It covers crucial themes like -1) the Acquired Immune Deficiency Syndrome and heroin addiction; 2) the effects of widespread cocaine use; 3) social use of marijuana; 4) early identification of and efficacy of treatment for alcoholism; and 5) the effects of social drinking during pregnancy on the fetus. This book will be of interest to scholars and researchers of addiction studies, psychology, sociology of addiction and specially those who wants to know about the advances made in the 1980s in the study of alcohol and substance abuse.
