  • Planarian Regeneration

    • Inglés
    Planarian Regeneration deals with regeneration problems including embryogenesis and morphogenesis. The book compares the principles involved in the regeneration processes with those in ontogenesis from the egg. The author also reviews the works of Thomas H. Morgan and Charles M. Child which became the basis for systematic scientific investigation of regeneration. The head regenerates vigorously, with a faster rate behind the eyes, then at various levels along the longitudinal axis of the planarian body. A time-graded regeneration includes inhibitory forces and some genetic codes that determine such rate. The time-graded field has been proven by transplantation experiments; the author addresses the morphological structure to which biochemical factors or processes determine the different rate of regeneration. He notes that the nervous system conforms to these processes as shown by studies of Lender and Klein (1961). The author suggests that the study of regeneration in planarians should involve time considerations quantitatively to explain some substance, if any, from the nervous system that activates the cytoplasm of neoblasts, and then the genome. This book will prove valuable for zoologists and researchers in genetics, biochemistry or molecular biology.

    • Inglés
    Human Settlements and Energy deals with the impact of energy considerations on human settlements planning and development. The book addresses the energy use, consumed mostly by human settlements, and the ways to conserve energy in these habitats. The text reviews the demand for energy, the principal uses of energy, and as the Economic Commission for Europe sees it, the need for human settlements to disconnect from heavy dependence on fast disappearing hydrocarbon fuels. The text examines two options as solution: nuclear-generated electricity (which many regard as undesirable) or reduce the growth of energy use. The book also examines the statement made by the Ottawa Seminar that "reducing energy consumption is a more difficult problem than increasing energy production." The book explains that policies on energy reduction should be a considered a global co-operative effort, moral obligation, as well as policies reflecting lifestyle changes, capital allocation, energy consciousness in physical planning (building design, automotive efficiency), and improved energy conversion. This book is helpful for environmentalists, conservationists, policy makers in the field of energy generation, conservation, or conversion, nuclear physicists, geothermal engineers, and scientists in the field of energy development research.

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.

    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.
