    • Inglés
    The Origins of Agriculture: An Evolutionary Perspective presents an alternative approach to understanding cultural variation and change. It aims to demonstrate that domestication and the origin of agricultural systems are best understood by attempting to explicate the evolutionary forces that affected that development of domesticates and agricultural systems. The book begins by discussing cultural change, the domestication of plants, and the origin of agricultural systems in the most general of terms. It considers Darwinism in some depth, concentrating on the relationship between natural selection and cultural change. Subsequent chapters examine the world of domestication and agriculture and present a series of concepts that may permit a more natural explanation for these processes. These include concepts such as incidental domestication, specialized domestication, and agricultural domestication. The final two chapters present models for the origin and spread of agricultural systems based upon Darwinian evolutionary theory.

    • Inglés
    Feedstuff Evaluation contains the proceedings of the 50th University of Nottingham Easter School in Agricultural Sciences, held at Sutton Bonington in July 1989. The book presents papers discussing a wide range of topics on the accurate evaluation of feedstuffs for livestock. Initially, systems of expressing the nutritive value of feeds are considered. Modifications to feeding value as influenced by animal factors including intake and palatability are discussed. Specific dietary ingredients, being plant polysaccharides, fats, minerals and vitamins are detailed. Prediction of the nutritive value of compound feeds and individual feeds through classical wet chemistry and the more recent NIR is assuming considerable importance in the rapid evaluation of diets. Associated with these developments is an appreciation of the relevance of both inter- and intra-laboratory variation in determinations. Finally, the need to collate information into an interactive data-base is being actively pursued. It is evident that safety of animal feeds is becoming an increasingly topical issue and the last session considered the relevance of naturally-occurring toxic factors, residues, mycotoxins and, finally, animal pathogens. Veterinarians, farmers, farm administrators, and those involved in every aspect of nutrient supply to animals will find the compendium very insightful and informative.

    Drug Therapy During Pregnancy is a collection of papers dealing with the risks and benefits of drug treatment for both mother and fetus. One paper notes that the total use of medication during pregnancy in the Netherlands has decreased from 82.7 % to 71.7 %. The paper also points out the lack of a relationship between the number or type of congenital anomalies and the use of medication. Another paper assesses fetal drug exposure in two ways: firstly, through the physicochemical characteristics of the drug and the way it is handled by the mother in order to estimate placental passage and fetal exposure. Secondly, through the utilization of pharmacokinetic models estimating the probable time course of drug concentrations in the feto-maternal unit. One paper investigates the effects of hypertension during pregnancy, in which the etiology of hypertension, a group of disorders with one common abnormality, remains unsolved with a clinical diagnosis that is not always accurate. Treatment differs widely depending on the type: chronic hypertension, albuminuric hypertension, and hypertensive crises during pregnancy. One paper suggests that to prove any environmental exposure to a particular substance affecting pregnancy, the exact timing of exposure must be established, large samples are necessary, possibly on a national or international scale. The paper cites as example the four-year documentation period of the 50% to 80% incidence of malformations due to thalidomide. General medicine practitioners, obstetricians, gynecologists, and researchers dealing with pharmacology, pharmocokinetics, toxicology, or embryology will find the collection valuable.

    • Inglés
    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.

    • Inglés
    The Evolution of Differentiation attempts to sketch the outlines of a framework from what is now known or suspected of the various aspects of differentiation in all types of organisms. This book surveys the many aspects of differentiation that are seen today, and in particular, because of the evident universality of expression of the genetic code, to enquire whether any similar universality exists in the methods of gene repression and activation. The information reviewed ranges from the chemical control of the genetic mechanisms of unicellular organisms during their various phases of activity, to the chemical control of differentiation in multicellular organisms both during embryonic development and in the adult state. Finally, some consideration is also given to that collapse of differentiation which leads to cancer.

    Hormone Action in Plant Development - A Critical Appraisal documents the proceedings of the Tenth Long Ashton Symposium, September 1986. The symposium was convened to assess the evidence for and against the view that plant hormones are endogenous regulators of plant development. The meeting also aimed to focus on and assess promising strategies for future research. The symposium opened with the Douglas Wills Lecture, given by Professor Carl Leopold. In many respects, progress in research on animal hormones seems greater than in the plant sciences and there may well be merit in following progress in animal hormone research as suggested by Professor Leopold. The symposium was comprised of four sessions. The introductory session considered the coordinating role of hormones in plant growth and development, and focused on hormone action at the molecular level, including their binding to receptors and their control of gene expression. The next two sessions embraced contributions on the experimental manipulation of development by genetic (notably by biochemical mutants), chemical (for example, with gibberellin/biosynth... inhibitors), and environmental (including drought stress) means. All these approaches consolidated the central importance of hormones in plant growth. In the final session, three speakers suggested some promising avenues for future research into the physiology, biochemistry, and molecular biology of plant hormones.
