Hair Analysis in Clinical and Forensic Toxicology


Book Description

Hair Analysis in Clinical and Forensic Toxicology is an essential reference for toxicologists working with, and researching, hair analysis. The text presents a review of the most up-to-date analytical methods in toxicological hair analysis, along with state-of-the-art developments in the areas of hair physiology, sampling, and pre-treatments, as well as discussions of fundamental issues, applications, and results interpretation. Topics addressed include the diagnosis of chronic excessive alcohol drinking by means of ethyl glucuronide (EtG) and fatty acid ethyl esters (FAEE), the early detection of new psychoactive substances, including designer drugs, the development of novel approaches to screening tests based on mass spectrometry, and the detection of prenatal exposure to psychoactive substances from the analysis of newborn hair. - Unites an international team of leading experts to provide an update on the cutting-edge advances in the toxicological analysis of hair - Demonstrates toxicological techniques relating to a variety of scenarios and exposure types - Ideal resource for the further study of the psychoactive substances, drug-facilitated crimes, ecotoxicology, analytical toxicology, occupational toxicology, toxicity testing, and forensic toxicology - Includes detailed instructions for the collection, preparation, and handling of hair, and how to best interpret results

Perspectives and Challenges of Hair Analysis


Book Description

Hair analysis is a reliable and widely used tool to evaluate drug exposure in many fields, including workplace testing, drug abuse history and withdrawal control, post-mortem toxicology, doping control, therapeutic drug monitoring of pharmaceuticals and even environmental exposure to toxic agents. Compounds incorporated into the hair structure resist hair growth and regular washing for several months, leading to a potential chronological trace of exposure, with farther periods corresponding to the hair segments more distant from the hair root. The relentless improvement of analytical procedures and instrumental technologies, together with the continuous introduction of new psychoactive substances, have led to an increasing number of studies and practical applications of hair analysis. This book is a comprehensive guide to hair analysis from general concepts, ideal for students and those new to the field, to interpretation and advanced methods for experts working in the area. With contributions from world-leading scientists in each field, this book describes state-of-the-art, emerging issues and recent analytical approaches to hair analysis that will serve as an essential tool to clinical and forensic toxicology laboratories across the globe.




Toxicological Aspects of Drug-Facilitated Crimes


Book Description

Toxicological Aspects of Drug-Facilitated Crimes provides readers with an overview of the field of DFC: its history, toxicological effects, analysis, interpretation of results, the roles that age, gender and race may play, and clinical presentations of these drugs. The most commonly used drugs in DFC are addressed (alcohol, cannabis, MDMA, and cocaine), as well as an emerging range of pharmaceuticals (benzodiazepines, hypnotics, sedatives, neuroleptics, histamine H1-antagonists, or anesthetics), which are becoming more widely used, but are more difficult to detect. Edited by a world-renowned expert in the field of Forensic and Analytical Toxicology, Pascal Kintz, this book investigates toxicants of emerging concern and brings together a number of experts in the field to address the most recent discoveries on DFC toxicology. - Brings together the latest research on the toxicological analysis of drug-facilitated crimes (DFC), with real-life case studies - Provides up-to-date analytical techniques for determining toxicity levels in blood, urine, and hair - Covers all types of toxicants involved in DFC, including alcohol, cannabis, MDMA, and a wide variety of pharmaceuticals







Surface Science and Adhesion in Cosmetics


Book Description

Activity in the arena of surface chemistry and adhesion aspects in cosmetics is substantial, but the information is scattered in many diverse publications media and no book exists which discusses surface chemistry and adhesion in cosmetics in unified manner. This book containing 15 chapters written by eminent researchers from academia and industry is divided into three parts: Part 1: General Topics; Part 2: Surface Chemistry Aspects; and Part 3: Wetting and Adhesion Aspects. The topics covered include: Lip biophysical properties and characterization; use of advanced silicone materials in long-lasting cosmetics; non-aqueous dispersions of acrylate copolymers in lipsticks; cosmetic oils in Lipstick structure; chemical structure of the hair surface, surface forces and interactions; AFM for hair surface characterization; application of AFM in characterizing hair, skin and cosmetic deposition; SIMS as a surface analysis method for hair, skin and cosmetics; surface tensiometry approach to characterize cosmetic products; spreading of hairsprays on hair; color transfer from long-wear face foundation products; interaction of polyelectrolytes and surfactants on hair surfaces; cosmetic adhesion to facial skin; and adhesion aspects in semi-permanent mascara; lipstick adhesion measurement.




Iodine

See how iodine can help: breast cancer, fibrocystic breast disease, detoxification, fatigue, Graves' Disease and Hashimoto's Disease. Find out why iodine deficiency may be the root cause of thyroid problems including hypothyroidism and thyroid cancer disease. Discover how to get iodine from your diet and improve your immune system"--p. 3 of cove.




Analytical and Practical Aspects of Drug Testing in Hair


Book Description

Many advances have been made since the publication of Drug Testing in Hair. The mid-1990s witnessed the progress in cannabis detection while the late 1990s focused on benzodiazepines detection and the applications in doping control. In more recent years, toxicologists centered on the detection in hair of a single exposure and the related applicatio




Drugs of Abuse


Book Description

A comprehensive review of the science of drug testing in all its aspects, placing emphasis on technologies that use body fluids other than urine for determining the presence of drugs of abuse. The authors discuss the various body fluid specimens suitable for testing for illicit drugs-particularly saliva, sweat, and hair-describe the structural and manufacturing aspects of on-site testing devices based on lateral flow immunoassay, and detail the pitfalls of using these specimens. They also discuss in detail the problem of sample adulteration and its detection. Since oral fluid has the best potential of succeeding urine as the next matrix of choice for drug detection, four popular saliva testing devices are examined: Intercept®, the Drager Drug Test®, Oratect®, and Drugwipe. Political, social, and legal issues are also considered in articles on privacy, the use of drug testing in courts, and the problem of sample adulteration.




Medusa's Hair


Book Description

The great pilgrimage center of southeastern Sri Lanka, Kataragama, has become in recent years the spiritual home of a new class of Hindu-Buddhist religious devotees. These ecstatic priests and priestesses invariably display long locks of matted hair, and they express their devotion to the gods through fire walking, tongue-piercing, hanging on hooks, and trance-induced prophesying. The increasing popularity of these ecstatics poses a challenge not only to orthodox Sinhala Buddhism (the official religion of Sri Lanka) but also, as Gananath Obeyesekere shows, to the traditional anthropological and psychoanalytic theories of symbolism. Focusing initially on one symbol, matted hair, Obeyesekere demonstrates that the conventional distinction between personal and cultural symbols is inadequate and naive. His detailed case studies of ecstatics show that there is always a reciprocity between the personal-psychological dimension of the symbol and its public, culturally sanctioned role. Medusa's Hair thus makes an important theoretical contribution both to the anthropology of individual experience and to the psychoanalytic understanding of culture. In its analyses of the symbolism of guilt, the adaptational and integrative significance of belief in spirits, and a host of related issues concerning possession states and religiosity, this book marks a provocative advance in psychological anthropology.
