The Molecular Biology of Neurological Disease reviews advances that have been made in understanding the molecular mechanisms of neurological disorders as well as immediate and future applications of molecular biological techniques to clinical practice. This book explores the molecular genetics of neurological disease such as muscular dystrophy, Joseph disease, and Huntington's disease, along with the mitochondrial genes implicated in such conditions. This text is comprised of 18 chapters and begins by introducing the reader to the basic principles and methods of molecular genetic techniques used in the diagnosis of neurological disease. Attention then turns to several aspects of genetic expression in the brain, including the extent to which the genome is expressed in the brain. The next chapter focuses on the visualization of polyadenylated messenger RNAs in individual cells in mammalian brain using in situ hybridization techniques, combined with immunohistochemical localization of specific proteins and neuropeptides implicated in diseases such as Alzheimer dementia. This book also discusses the molecular biology of chemical synaptic neurotransmission; proteins involved in the regulation of nervous system development; and gene expression in skeletal muscle. This text then concludes with a summary of the ""neurological gene map"" as it stands in the latter part of 1987. This book is intended for physicians who grapple with the problems of neurological disorders on a daily basis, including neurologists, neurologists in training, and those in related fields such as neurosurgery, internal medicine, psychiatry, and rehabilitation medicine.

Animal Feeding Stuffs Legislation of the UK: A Concise Guide offers a guide to legislation governing the production, sale, and distribution of animal feeding stuffs in the UK. Individual statutory instruments are discussed and categorized according to their relevance to raw materials, straight feeding stuffs, compound feeds, medicated feeds, and additives. Sampling, the rights of inspectors under different acts and regulations, codes of practice, and labeling requirements are also considered. This guide is comprised of nine chapters and begins with an overview of UK laws governing the manufacture and supply of animal feeding stuffs, including Agriculture Act 1970 Part IV, Medicines Act 1968 and Regulations made under it, and Animal Health and Welfare Act 1984. The next chapter presents a definition of terms, including those applied to animals with respect to the UK feed regulations. The reader is then introduced to statutory statements for raw material or straight feeding stuff; compound feeding stuffs; and additives and premixtures. This book also considers the registration system for manufacturers and qualifying on-farm mixers, along with licensing requirements for products to be used in feeds. The final chapter is devoted to statutory requirements for sampling and analysis of animal feeding stuffs. This monograph will be a helpful and authoritative resource for feed manufacturers, raw materials suppliers, technical advisors, enforcement agencies, and students of feed and livestock production.

Butterworths International Medical Reviews, Clinical Pharmacology and Therapeutics 1: Presystemic Drug Elimination explores the principles of presystemic drug metabolism in human based on animal studies. This book is divided into four sections encompassing 10 chapters that specifically describe the extent of metabolism occurring in the gastrointestinal tract, liver, and lung. Section 1 focuses on presystemic elimination by the gastrointestinal tract. This section discusses the enzymatic biotransformation in the gastrointestinal mucosa and the ability of the microflora to metabolize drugs. Section 2 considers the contribution of the liver to presystemic drug elimination, with a particular emphasis on the physiological factors, which determine the rate of breakdown of drugs in vivo. This section also deals with the effects of hepatic cirrhosis on presystemic drug elimination. Section 3 presents first a brief outline of the knowledge of pulmonary structure and relevant physiology, followed by a discussion on “first-pass” metabolism of endogenous substrates and drugs across the pulmonary circulation and of environmental chemicals after inhalation. This section also provides the methods for distinguishing between the contribution of the various sites to presystemic drug elimination and the problems associated with attempts to analyze available pharmacokinetic data. This work is an ideal source for clinical pharmacologists and researchers.

The Voluntary Food Intake of Farm Animals offers a wide discussion on food intake among farm animals. The book presents various studies, facts, details, and theories that are relevant to the subject. The first chapter begins by explaining the basic definition and significance of voluntary food intake. This topic is followed by discussions on meal patterns, the main features of eating, and the similarities between species. The next chapter explores theories about the food intake control, which are divided into two types: single-factor theories and multiple-factor theories. In Chapter 3, the discussion is on the food’s pathway, including elaborations on the various receptors. Chapter 4 considers the central nervous system’s involvement in the voluntary food intake and the energy balance regulation. The next couple of chapters highlight the possible reasons that affect food intake; among them are pregnancy, fattening, physical growths, and the environment. In the book’s remaining chapters, the discussion revolves around grass intake and the prediction and manipulation of voluntary food intake. The book serves as a valuable reference for undergraduates and postgraduates of biology and its related fields.

Control of Pig Reproduction focuses on carefully evaluated techniques and technologies involved in the control of pig reproduction. The selection first ponders on the sexual development of male pigs, including early fetal, perinatal, and pubertal periods. The text also discusses testicular steroids and boar taint; interrelationships between spermatozoa, female reproductive tract, and egg investments; and artificial insemination. Discussions focus on androgens, estrogens, deposition of semen and uterine transit, sperm regulation and release by the isthmus, and types of artificial insemination. The manuscript examines endocrine control of sexual maturation in female pigs and sexual differentiation of the stimulatory estrogen feedback mechanism and factors affecting the natural attainment of puberty in gilts. Discussions focus on development of ovarian function and gonadal steroid levels; development of the stimulatory estrogen feedback mechanism; and maturation of negative feedback of gonadal steroids. The text also takes a look at controlled induction of puberty, endocrine control of the estrus cycle, and control of ovulation. The selection is a valuable reference for farmers and readers interested in pig reproduction.
