The mechanism of information transfer between cells is the subject of Introduction to Signal Transduction. Until recently various aspects of signaling by hormones were studied (and taught) under the subject of endocrinology, and signaling by neurotransmitters was the subject of neurochemistry. With growing awareness of the many similarities between hormonal and neurotransmitter signalling, recent years have witnessed the emergence of Signal Transduction as an independent discipline covering all aspects of information transfer between cells irrespective of the nature and source of the signals. This book is designed for senior undergraduate/graduate-level students interested in a basic understanding of the major participants in the cellular Signal Transduction pathways. The book covers the major topics in Signal Transduction: receptors, which recognize the signals at the cell surface; G-proteins, which transduce the signals; and adenylate cyclases, guanlate cyclases, and phospholipases, which generate second messengers. Chapters also focus on ion channels, phosphodiesterases, protein kinases, phosphoprotein phosphatases and nitric oxide, which participate in the cellular response to signals; the health consequences of defects in Signal Transduction proteins; and the central role Signal Transduction plays in drug abuse. The book is suitable for an introductory course in Signal Transduction as well as for self-study and review. It is recommended for biology and medical students, as well as for interdisciplinary science majors and pharmaceutical researchers.

Fatty acids play an important role in the barrier function of skin and represent a major source of proinflammatory mediators such as prostaglandins, leukotrienes and other lipids in inflammatory skin disorders. This book combines the two major functions of fatty acids in skin biology. In the first part the biosynthesis of fatty acids in skin with its role in barrier function as well as the role of dietary fatty acids on skin cell function and in the treatment of inflammatory skin diseases is presented. The second part deals with skin as a source of proinflammatory eicosanoids, especially with the keratinocyte as a major cellular source. Metabolism of eicosanoids in skin, its role in psoriasis and atopic dermatitis as well as pharmacological inhibition of eicosanoid biosynthesis is reviewed. The book finishes with a chapter describing the methods used for quantification of fatty acids and derivatives in skin inflammation. Anyone interested in skin physiology would benefit from the overviews about the two sites of fatty acids' function in skin integrity and in skin inflammation.

The birth of Dolly -- the world's first clone -- placed in our hands the secret of creation. Few discoveries have so altered our notion of what it means to be human, or presented such a Gordian knot of ethical, spiritual, and scientific questions. Noted science journalist Gina Kolata broke the news nationally in The New York Times and was the first reporter to speak with Dr. Ian Wilmut, the embryologist who cloned Dolly. Now Kolata reveals the story behind Dolly, interweaving the social and cultural tales of our fear and fascination with cloning, reaching back nearly a century, with the riveting scientific accountof how a clone came to be and the mind-boggling questions Dolly presents for our future.

Clone is a compelling blend of scientific suspense, dreams dashed, and frauds exposed, with provocative philosophical questions and an astute assessment of why Dolly's birth was only possible now. Like The Making of the Atomic Bomb, Lucy, and Chaos, this book gives us a window on history in the making, and an understanding of its profound effect on our lives.

This is a companion volume to the author's Medicinal Plant Alkaloids, published by University of Toronto in 1965. It consists of descriptions and discussion of selected groups of plant glycosides of medicinal significance, and bridges the gap, for pharmacy students, between general references in the standard textbooks on the one hand and the more advanced coverage given in specialized reference books and research journals on the other.

Kunstliche Organe sind Membranmodule, welche in einem extrakorporalen Kreislauf Blutinhaltsstoffe austauschen bzw. entfernen. Dabei kommen die klassischen Prinzipien der Crossflow- und der Gegenstromverfahren zur Anwendung. Manfred Raff zeigt, wie fur die Auslegung derartiger Membranverfahren aus Modellen am differentiellen Membranelement funktionale Zusammenhange von Zielgroessen und geometrischen, stofflichen und Betriebsparametern fur das gesamte Modul abgeleitet werden. Die Ergebnisgleichungen koennen auch fur technische Anwendungen eingesetzt werden.

Automated counters provide data on blood samples with greater speed and precision than manual microscopic methods, but generate reports with unfamiliar terms as well as previously unavailable types of information. "Automated Blood Counts and Differentials" gives the first in-depth examination of this new technology, the data it provides, and their value for hematologic analysis.

This manual offers practical guidelines for evaluating automated blood count results and discusses technical aspects of instrumentation that underline measurement values and artifacts. Chapters on red cells, platelets, and white cells cover basic pathophysiology and clinical interpretation of the most common abnormal blood counts, with individual sections on specific conditions. Ten illustrative case examples give readers an opportunity to interpret data. The book is liberally illustrated and emphasizes correlations between automated hematology and manual blood smear morphology to show how the two methods best complement each other.

Making full use of automated blood counts is a challenge that faces technicians operating the equipment, pathologists working with the results, and physicians receiving the reports. "Automated Blood Counts and Differentials" will help readers develop expertise in interpreting the data gathered by this new diagnostic tool

La diagnostica per immagini ha subito in questi anni una notevole trasformazione legata in primo luogo al rapido sviluppo tecnologico. Di pari passo con il miglioramento delle metodologie di acquisizione in tomografia computerizzata e risonanza magnetica, si sono affermate nella pratica clinica le tecniche di elaborazione bidimensionale e tridimensionale delle immagini diagnostiche.

Concepito come riferimento per gli studenti del corso di Laurea in Tecniche di Radiologia Medica per Immagini e Radioterapia, per la preparazione dell esame di "Produzione e trattamento delle immagini diagnostiche," il volume si rivolge anche ai medici specializzandi in radiodiagnostica e in medicina-nucleare, i quali non possono non conoscere le basi tecniche della formazione ed elaborazione delle immagini.
