Toxicology of Skin

by Howard I. Maibach

Toxic injury to the skin in the general population, and particularly in western populations, is on the increase. This is partly due to the expanding number of natural and man-made chemicals present in our everyday environment. The need for a thorough understanding of the skin, and the mechanisms of toxicity therein, has never been more pressing. Th

Toxicology of the Gastrointestinal Tract, Second Edition (Target Organ Toxicology Series)

by Shayne Cox Gad

The gastrointestinal tract is the most important of the three major routes of entry (and clearance) of xenobiotics and biologic entities into the bodies of mammals. As such, it is also the major route for administration of pharmaceuticals to humans. Gastrointestinal Toxicology, Second Edition describes the mechanism for entry and clearance of xenobiotics, as well as the barriers, immunologic and metabolic issues, and functions present in the GI tract. Appearing in this volume are also considerations of the microbiome and its actions and influence on the function of the GI tract and on the toxicity and pharmacodynamics of ingested substances (including nutrients, toxins, and therapeutics). These fifteen chapters written by experienced experts in the field address methods to evaluate GI function; specifics of GI function and toxicity assessment in canines and minipigs; classes of compounds with their toxicity; species differences; and the toxicity (and promise) of nanoparticles. Those needing to understand the structure, function, and methods of studying the GI tract will find this volume a singular source of reference.

Toxikologie für alle: Wann ist ein Stoff gefährlich?

by Helmut Greim Heidrun Greim

Was man über Giftstoffe, deren Wirkung und Bewertung wissen muss: Zwei erfahrene Toxikologen erklären allgemeinverständlich, wann ein Stoff zum Schadstoff wird. Der Schwerpunkt liegt dabei auf den allgemeinen Grundlagen einer toxikologischen Untersuchung und Bewertung von Schadstoffen, sowie den daraus abgleiteten Handlungsempfehlungen. Anhand bekannter Beispiele aus den letzten Jahren, u. a. des Unkrautvernichters Glyphosat oder des Insektizids Fipronil, die beide in Nahrungsmitteln nachgewiesen wurden, wird erläutert, wie konkrete Gesundheitsgefährdungen anhand toxikologischer Daten und Verfahren ermittelt und welche Maßnahmen zum Schutz der Gesundheit daraus abgeleitet werden. Die Anwendung der toxikologischen Verfahren für die Bewertung von Gesundheitsrisiken wird anhand von Beispielen aus dem Alltag anschaulich dargestellt, von Lebensmitteln über Kosmetika bis hin zu Arzneimitteln und Alltagsprodukten. Ein kompakter, aber fundierter Einstieg in ein wichtiges und oft kontrovers diskutiertes Thema - für alle, die Toxine und deren Wirkungen auf Mensch und Umwelt verstehen wollen.

Toxikologie und Rechtskunde: Kompetenzfördernde Wissensvermittlung der Gefahrstoffkunde

by Peter-Jürgen Kramer

Auf dieses Buch haben Lehrende und Studierende in Chemie, Biochemie, aber auch in anderen chemienahen Fachgebieten lange gewartet. Dieses Buch ist ideal für Lehrende und Studierende im Fach Gefahrstoffkunde an Hochschulen und Universitäten, denn es bietet ihnen das Rüstzeug für die Gestaltung erfolgreicher Lehrveranstaltungen bzw. für einen erfolgreichen Abschluss in diesem Studienfach.Die Besorgnis, dass chemische Stoffe eine Gefährdung für die Gesundheit der Menschen und ihrer Umwelt darstellen können, ist begründet. Chemische Stoffe können schädigen, und daher gefährlich sein. Die zahlreichen Berichte von dramatischen Chemieunfällen und Umweltkatastrophen wie die von Seveso (1976) und Basel (1986) sind präsent und prägen das Bewusstsein in Gesellschaft und Politik. Nach den Gründen, warum die Geschichten katastrophaler Chemieunfälle in der Vergangenheit liegen und in heutiger Zeit in der europäischen Welt nicht mehr vorgekommen sind, wird jedoch selten gefragt.Dabei ist die Antwort auf diese Frage einfach: Die in der Chemie arbeitenden Menschen und die Behörden haben gelernt, mit den Gefährdungen und Risiken, die von chemischen Stoffen ausgehen, kompetent umzugehen. Die angewandte Wissenschaft, die diese Kompetenz vermitteln muss, ist die Gefahrstoffkunde, eine Kombination aus Toxikologie und Rechtskunde, im Studium ein Pflichtfach für jede Chemikerin und jeden Chemiker, aber auch für weitere Studiengänge, bei denen chemische Stoffe eine wichtige Rolle spielen. Der mit dem erfolgreichen Abschluss im Fach Gefahrstoffkunde verbundene amtliche Sachkundenachweis muss auch nach dem Studium regelmäßig aktualisiert werden.

Newly divorced surgeon Dr. Kim Regis is determined to remain a good father to his only son, Selden. On a special night out, Kim takes Seldon to his favorite fast-food restaurant for a feast of burgers and fries. <P><P>But the good time turns to tragedy: the young boy becomes gravely ill and dies as a result of poisoning by E. coli. bacteria found in the meat. <P> Was Seldon's death a result of shoddy food-handling practices? Or was it a sophisticated case of product tampering - by a rival fast-foot giant or a disgruntled employee? Or perhaps by someone with a score to settle with Kim? Taking a leave from his surgical practice, Kim devotes his energies to solving the mystery full time. But he immediately hits a brick walls: a code of silence more impenetrable than anything he has ever encountered in his medical career. Instead of a cold-shoulder reception, however, Kim is soon met with a boot and a fist as thugs attempt to quash his inquiry. <P> Aided by his ex-wife, Kim pursues a trail of deadly evidence, uncovering complicity and guilt stretching from the slaughterhouse floor to the corporate boardroom. Racing against time before more are poisoned, the two come face-to-face with the shocking and elusive truth. And in their life-and-death search for answers, they rediscover the reasons they first fell in love. <P> With trademark pulse-pounding flair, Robin Cook delivers a cutting-edge thriller, borrowing from today's fears and tomorrow's medical technology.

Toxins and Hemostasis

by Francis S. Markland Kenneth J Clemetson Mary Ann Mclane R. Manjunatha Kini Takashi Morita

Circulation of blood is vital for the survival of vertebrates, including man. Mainly, it plays an important role in carrying food nutrients and oxygen to every tissue and organ and in removing all waste products and carbon dioxide. Any imbalance in the hemostatic and cardiovascular systems can lead to death and severe debility. A number of animals have developed mechanisms to target these systems and exploit the vulnerability. In some species (for example, snakes), such mechanisms are used to immobilize and kill the victim/prey, whereas in others (for example, insects, such as leaches, mosquitoes and ticks), they are used to provide a continuous supply of blood. These mechanisms include, but are not limited to, procoagulant and anticoagulant actions that affect the coagulation cascade and platelet aggregation, as well as altering vasodilatory responses. In all these various animals, these mechanisms have evolved to perfection over millions of years to support their survival. In last 3-4 decades, due to the efforts of scientists from various backgrounds including biology, protein chemistry, molecular biology, pharmacology, hematology, and structural biology, significant progress in understanding the structure-function relationships, as well as the mechanism of action have been made in a number of exogenous factors that affect blood coagulation, platelet aggregation and vasodilation from various animals. These exogenous factors have contributed significantly to the development of research tools as well as providing new therapeutic agents. With the increase average age of the population coupled with changes in life style in recent years, there has been a significant increase in cardiovascular and hematological disorders. Thus scientists in both academic institutions as well as the pharmaceutical industry are developing better therapeutic agents to improve the quality of life. This impetus has lead to the search for novel agents from various sources that interfere with cardiovascular and hematalogical processes. Although at first glance exogenous factors appear to function as 'villains', several life-saving drugs have been developed based upon these factors. Such drugs or drug leads include those that inhibit the angiotensin converting enzymes (Captopril and Enalapril), that block platelet receptors (Eptifibatide and Tirofiban), or that digest thrombotic plugs (Alfimeprase and bat plasminogen activator) to name a few. Several new and exciting success stories are currently unfolding. In this book, recent studies on some of the exogenous factors that play crucial roles in cardiovascular and hematological disorders are reviewed in order to consolidate the efforts in this area of research and to recruit new, talented researchers. The 25-30 review chapters, each written by experts in their field, compiled herein are devoted to exogenous factors affecting platelet aggregation, anticoagulant and procoagulant proteins, fibrinolytic proteins and hypotensive agents (For details see, Contents of the Book). This book is intended to help to create elevated awareness and enthusiasm in the field of exogenous factors. I believe that this book will provide greater impetus to the search for novel proteins based on naturally occurring exogenous factors. This will be the first book dealing extensively with exogenous factors in the last 25 years. The book will provide a ready reference to the different approaches used to solve complex problems in protein chemistry and pharmacology of exogenous factors. The book will update our understanding of the structure-function relationships and mechanisms of action of exogenous factors and provide great insights into future directions for solving the remaining challenges.

Toxins and Other Harmful Compounds in Foods (Chemical & Functional Properties of Food Components)

by A. Witczak Zdzislaw Sikorski

Toxins and Other Harmful Compounds in Foods provides information on the contents, distribution, chemical properties, and biological activity of toxins and other harmful compounds in foods that are natural components of the raw materials, accumulated due to microbial actions and environmental pollution, or are generated due to processing. This book shows how different factors related to the production of raw materials, as well as to storage and processing conditions, affect the presence and concentration of toxins and other harmful compounds in foods. It shows how various regulations, as well as unit operations and processes used in food production, may eliminate different toxins or generate new ones. The real health hazards for the consumers resulting from the presence of toxic/harmful compounds in aliments are discussed, and various national and international regulations obligatory in agriculture and industry aimed at increasing food safety are presented. Methods of analysis used for detection and determination of undesirable compounds are also discussed, making it possible to understand the effect of storage and processing parameters, as well as systems of quality assurance, on food safety and to select optimum procedures for analytical control.

Toxins and Targets

by David Maguire Dianne Watters John Pearn Martin Lavin

First Published in 1992. The last decade of the twentieth century has seen an unprecedented advocacy for the preservation of a safe environment, and the prevention of ill-health from toxic chemicals. Human activity, however, is responsible for introducing new toxins into the environment. In order to control competitors for human food sources, an armament of pesticides has been assembled and their widespread and largely uncontrolled application has been permitted. It is only when the health of the population begins to suffer from the effects of these chemicals that the efficacy of their use is questioned. Decision-makers whose roles involve the promotion and control of the environment must look to lessons that can be learnt from biosystems that include animals other than man. Toxins and Targets details the way in which organisms from diverse habitats in the plant and animal kingdoms have adapted to handle toxins safely. Part I, on the aquatic environment, highlights the means by which marine organisms have adapted their toxins to be effective in a world of high aqueous solubility and infinite dilution. Part II deals with venomous terrestrial organisms and the mechanisms by which they damage animal cells, and Part III considers the way in which human society attempts to investigate toxicity and to control both synthetic and naturally occurring poisons. The development of a safe environ­ment depends on increased knowledge and novel approaches to solving escalating problems. This book is a step towards this end.

Toxoplasmosis of Animals and Humans

by J. P. Dubey

This is the only book to cover toxoplasmosis of animals and humans thoroughly in one single source. Found worldwide from Alaska to Australasia, Toxoplasma gondii is the cause of one of the most common parasitic infections in humans, livestock, companion animals, and wildlife, and is included on the list of potential bioterrorism microbes. Furthermore, T. gondii has been and continues to be used extensively as a model for the cell biology of apicomplexan parasites. In the decade since the second edition of this book was published, there has been an explosion of knowledge concerning the parasite Toxoplasma gondii and toxoplasmosis. This update provides unique information on all known host types for this parasite, with an additional chapter on history, substantial updates throughout, and a detailed focus on the biology of the parasite in Chapter 2. The third edition is compiled by author JP Dubey, an authority on T. gondii who has worked with virtually all hosts of the protozoan during the last 55 years, including humans, all livestock species, wildlife, and zoo animals. The book distills the voluminous and potentially confusing scientific literature, that has grown geometrically in the 30+ years since the publication of the first edition, into a comprehensive resource for all professionals, graduate students and researchers working in this field.
