The motivation for us to conceive this series of volumes on regulation was mainly our belief that it would be fun, and at the same time productive, to approach the subject in a way that differs from that of other treatises. We thought it might be interesting and instructive for both author and reader-to examine a particular area of investigation in a framework of many different problems. Cutting across the traditional boundaries that have separated the subjects in past volumes on regulation is not an easy thing to do-not because it is difficult to think of what interesting topics should replace the old ones, but because it is difficult to find authors who are willing to write about areas outside those pursued in their own laboratories. Anyone who takes on the task of reviewing a broad area of interest must weave together its various parts by picking up the threads from many different laboratories, and attempt to produce a fabric with a meaningful design. Finding persons who are likely to succeed in such a task was the most difficult part of our job. In the first volume of this treatise, most of the chapters dealt with the mechanisms of regulation of gene expression in microorganisms. The second volume involved a somewhat broader area, spanning the prokaryotic-eukaryotic border. Topics ranged from phage morphogenesis to the role of gradients in development. This third volume-Volume 3A concerns hormones, as does the forthcoming companion volume-Volume 3B.
An account of the 1878 yellow fever epidemic documents how it killed more than 18,000 people in the American South, tracing its particularly catastrophic impact in Memphis, Tennessee, while noting the heroic efforts of people who remained behind to help.
The Fifth Edition of Greenfield's Surgery has been thoroughly revised, updated, and refocused to conform to changes in surgical education and practice. Reflecting the increasingly clinical emphasis of residency programs, this edition features expanded coverage of clinical material and increased use of clinical algorithms. Key Points open each chapter, and icons in the text indicate where Key Points are fully discussed. Many of the black-and-white images from the previous edition have been replaced by full-color images. This edition has new chapters on quality assessment, surgical education, and surgical processes in the hospital. Coverage of surgical subspecialty areas is more sharply focused on topics that are encountered by general surgeons and included in the current general surgery curriculum and ABSITE exam. The vascular section has been further consolidated. A new editor, Diane M. Simeone, MD, PhD, has joined the editorial team. This edition is available either in one hardbound volume or in a four-volume softbound set. The lightweight four-volume option offers easy portability and quick access. Each volume is organized by organ system so you can find the facts you need within seconds. The companion website presents the fully searchable text, an instant-feedback test bank featuring over 800 questions and answers, and a comprehensive image bank. Unique to this new edition's website are 100 "Morbidity and Mortality" case discussions. Each case reviews a specific surgical complication, how the complication was addressed, and reviews the literature on approaches and outcomes.
