  • Food Legislative System of the UK

    • 1 Edición
    • Stephen J. Fallows
    • Inglés
    Food Legislative System of the UK discusses the principles underlying the country's food laws, the historical context of today's food legislation, and the process for amendments in legislation. The book also reviews the influences on the system such as those arising from interest groups, the changing diet, and health environment. In addressing the Food Legislative System of the United Kingdom, the book tackles various examples of food legislation and numerous food- related advisory bodies. Industry, consumer, or enforcement pressures can initiate changes and modifications of laws. Once ministers are convinced that a prima-facie case exists for amending food legislation, they will seek advice from various authorities; make a draft, and present it for full parliamentary procedure. For example, the "Food and Environment Bill" has passed through Parliament by ministers representing the Ministry of Agriculture, Fisheries and Food, while the "Food Bill" has gone through another route with the chief legal officers and company. The book emphasizes the mechanisms through which change is achieved, as well as the points when opportunities exist for interest groups to make their views known to the decision makers. The book can be helpful for food lobbyists, consumer food groups, nutritionists, political scientists, and heads of food and welfare organizations.

    • Heinz Köhler + 2 más
    • Inglés
    Idiotypy in Biology and Medicine aims to serve the increasing interest and involvement in the practical aspects of idiotypy in biological systems. The concept of idiotypy has received wide recognition and interest far beyond the area of immunology. Experiments and interpretation of findings, reported here, clearly support the general nature of the idiotype concept in manipulating biological systems to correct pathological conditions or to improve the immune adaptation to environmental factors. The book is organized into three sections. Section 1 discusses original concepts of idiotypic manipulations. It reviews old and recent data important for the concept of an idiotype network and reports on attempts to deal with the T-cell receptor paradox; explains the immune system in terms of a circular idiotype network that can be demonstrated by sequential immunization; and emphasizes the need for restrictions in network interactions. Section 2 addresses the role and activity of idiotypic and antiidiotypic antibodies in the regulation of the immune system. Section 3 takes the issue of idiotype-antiidiotyp... out of the realm of the immune system and discusses it as a new principle to analyze and manipulate biological systems in general.

  • The Hallucinogens

    • 1 Edición
    • A. Hoffer + 1 más
    • Inglés
    The Hallucinogens attempts to provide a detailed description of the hallucinogens in a single volume. Hallucinogens are chemicals which in nontoxic doses produce changes in perception, in thought, and in mood, but which seldom produce mental confusion, memory loss, or disorientation for person, place, and time. These latter changes are characteristic of organic brain reactions following intoxications with alcohol, anesthetics, and other toxic drugs. The book covers the following hallucinogens: plant ß-phenethylamines, d-lysergic acid diethylamide, ololiuqui, indole hallucinogens derived from tryptophan, and taraxein. The discussions include their chemistry, biochemistry, and neurophysiological effects. The final chapter deals with animal studies with hallucinogenic drugs. This work has been written for chemists, biochemists, psychologists, sociologists, and research physicians. While it cannot satisfy each group fully, it is sufficiently comprehensive and well documented so that each group can use it as a springboard for future enquiry into these fascinating chemicals.

  • Heredity and Environment in the Functional Psychoses

    An Epidemiological–Clinical Twin Study
    • 1 Edición
    • Einar Kringlen
    • Inglés
    Heredity and Environment in the Functional Psychoses involves an epidemiological clinical study of twins carried out at the University Psychiatric Institute in Oslo. The author reviews the history and nosological aspects of psychiatry. In his study of twin genetics, the author seeks to answer the questions "What is inherited?" and "How is it inherited?" In his review of 342 pairs of twins in the Central Register of Psychosis, his study had the following aims: to obtain true concordance figures for all types of functional psychoses; to study problems pertaining to nosology; and to study a larger sample of discordant pairs in order to clarify crucial environmental factors. His findings show that concordance figures for schizophrenia are 25-38 per cent in monozygotic twins and 4-10 per cent ion dizygotic twins. He points out that the difference in such concordance rates between the two types of twins is statistically significant. The data supports the (weak) assumption of a genetic factor in the etiology of schizophrenia. Behavioral scientists, psychiatrists, child psychologists, and researchers involved in genetics will find this book helpful and informative.

    Birds: Brain and Behavior is a collection of papers that discusses brain-behaviors problems concentrating on the bird's complex and well-integrated central nervous system. This collection reviews the theoretical and methodological problems concerning comparative studies of bird behavior in a brain-behavior relationship. The book explains the structural organization of the avian brain including the spinal cord and the general ascending/descending patterns of sensory projections. One paper analyzes the hearing and vocalization in songbirds that are composed of the auditory mechanisms, as well as the vocalization and audition systems. A study by Falls (1963) notes that songbirds use more than one type of auditory cue for species recognition. Another paper present brain stimulation parameters that affect bird vocalization. Other papers examine the neural basis of avian discrimination and reversal learning, memory disruptions by brain perturbation, and the behavioral and physiological correlations between the sleep and awake states. This book will prove useful for avian biologists, zoologists, and readers who have a general interest in birds.

    Methods in Toxicology, Volume 3: Male Reproductive Toxicology, Part A, deals with the male reproductive system and discusses methods that will help identify toxicant-induced changes at all levels in living organisms. It is important to realize that a toxic effect does not occur in a vacuum. All work in toxicology must be predicated on a demonstrated adverse effect in vivo. If good toxicology cannot exist in a vacuum, then there must be a structure. Thus, the book begins by presenting a few models as examples of the ways experiments could be grouped to define the toxicity of a chemical. This is followed by separate chapters on methods such as male mouse sexual behavior test; in vitro techniques for assessing pituitary secretory function; histological methods for preservation of the rat testis; procedures for assessing testicular sperm head counts in mice, rats, and dogs; and guidelines for conducting rodent dominant lethal tests. Subsequent chapters cover topics such as methods for the isolation and purification of Leydig cells from rat and mouse testes, and techniques used in semen analysis and fertility assessment in the rabbit.

    Photoprocesses, Photoreceptors, and Evolution discusses the important role that visible radiation has played in the development of photoreceptor systems, hence, in the evolution of life on earth. The book examines the spectrum of energies that impinge on the Earth, what kinds of molecules absorb these energies, and how they are structured within the cell to function as a photoreceptor system. The text describes the molecular structure of the cell membrane; the various kinds of pigment molecules; and the structures associated with photobiological phenomena. The relationship between the photoreceptor system and behavior, i.e. phototropism and phototaxis, photosynthesis, and vision, is also considered. The book further tackles the photoprocesses which function in photoperiodic phenomena - the “biological clocks”, aging, memory, and bioluminescence. The text then demonstrates the structure of the invertebrate and vertebrate photoreceptors; and the intervebrate and vertebrate visual pigments and their photochemistry. Photobiologists will find the book invaluable.

  • Agrammatism

    • Inglés
    Agrammatism provides an overview of the state of knowledge on agrammatism, typically defined as a disorder of sentence production involving the selective omission of function words and some grammatical endings on words. The book opens with discussions of the diversity of the disorder. This is followed by separate chapters that address primarily questions of syntactic structure in agrammatism, from both linguistic and psycholinguistic perspectives. Within these two gross sections there is no consensus among the conclusions reached by the various authors. However, the position is taken that agrammatism is a disorder distinct from other aphasie disorders of sentence structure. This position is reconsidered in the final two chapters. Because of the intrinsically interdisciplinary character of research on agrammatism, it is hoped that the work presented in this volume will be of interest to linguists and psycholinguists working in areas outside the domain of aphasia, as well as to neurolinguists and neuropsychologists who are already involved in the study of language deficits.
