Mechanism, Experiment, Disease


Book Description

A leading early modern anatomist and physician, Marcello Malpighi often compared himself to that period’s other great mind—Galileo. Domenico Bertoloni Meli here explores Malpighi’s work and places it in the context of seventeenth-century intellectual life. Malpighi’s interests were wide and varied. As a professor at the University of Bologna, he confirmed William Harvey’s theory of the circulation of blood; published groundbreaking studies of human organs; made important discoveries about the anatomy of silkworms; and examined the properties of plants. He sought to apply his findings to medical practice. By analyzing Malpighi’s work, the author provides novel perspectives not only on the history of anatomy but also on the histories of science, philosophy, and medicine. Through the lens of Malpighi and his work, Bertoloni Meli investigates a range of important themes, from sense perception to the meaning of Galenism in the seventeenth century. Bertoloni Meli contends that to study science and medicine in the seventeenth century one needs to understand how scholars and ideas crossed disciplinary boundaries. He examines Malpighi’s work within this context, describing how anatomical knowledge was achieved and transmitted and how those processes interacted with the experimental and mechanical philosophies, natural history, and medical practice. Malpighi was central in all of these developments, and his work helped redefine the intellectual horizon of the time. Bertoloni Meli’s critical study of this key figure and the works of his contemporaries—including Borelli, Swammerdam, Redi, and Ruysch—opens a wonderful window onto the scientific and medical worlds of the seventeenth century.




Mechanism


Book Description

The mechanical philosophy first emerged as a leading player on the intellectual scene in the early modern period—seeking to explain all natural phenomena through the physics of matter and motion—and the term mechanism was coined. Over time, natural phenomena came to be understood through machine analogies and explanations and the very word mechanism, a suggestive and ambiguous expression, took on a host of different meanings. Emphasizing the important role of key ancient and early modern protagonists, from Galen to Robert Boyle, this book offers a historical investigation of the term mechanism from the late Renaissance to the end of the seventeenth century, at a time when it was used rather frequently in complex debates about the nature of the notion of the soul. In this rich and detailed study, Domenico Bertoloni Melifocuses on strategies for discussing the notion of mechanism in historically sensitive ways; the relation between mechanism, visual representation, and anatomy; the usage and meaning of the term in early modern times; and Marcello Malpighi and the problems of fecundation and generation, among the most challenging topics to investigate from a mechanistic standpoint.










Mechanisms in the Pathogenesis of Enteric Diseases 2


Book Description

This book, Mechanisms in the Pathogenesis of Enteric Diseases 2, is an out come of the Second International Rushmore Conference on Mechanisms in the Pathogenesis of Enteric Diseases, held September 3D-October 3, 1998 in Rapid City, South Dakota, USA. Its chapters represent many of the reviews and papers presented at the conference. The meeting was organized by members of the North-Central Regional Research Committee "NC-62", a consortium of researchers of bovine and swine enteric diseases from land-grant institutions supported by the United States Department of Agriculture. The Rushmore Conferences were conceived as a forum for an interdiscipli nary discussion of mechanisms of infectious enteric diseases. It was intended that such a discussion would stimulate cross-pollination of ideas, and nurture synergistic collabora tions among scientists who might otherwise not interact. Enteric diseases are caused by widely divergent pathogens and parasites in broadly different settings, and affect multi ple organ systems. Some enteric diseases affect a single species, while others may affect multiple species, perhaps including human beings. Some enteric diseases were present in antiquity, while others have recently emerged. Knowledge regarding a particular disease or pathogen has frequently proven useful in understanding another disease or pathogen, because common themes in pathogenesis exist. As this knowledge base grows,strategies in the prevention and control of various enteric diseases often converge. Cross-discipli nary discussions and collaborations facilitate growth of this knowledge base, as well as development of tools for disease interdiction.




Evaluating Evidence of Mechanisms in Medicine


Book Description

This book is open access under a CC BY license. This book is the first to develop explicit methods for evaluating evidence of mechanisms in the field of medicine. It explains why it can be important to make this evidence explicit, and describes how to take such evidence into account in the evidence appraisal process. In addition, it develops procedures for seeking evidence of mechanisms, for evaluating evidence of mechanisms, and for combining this evaluation with evidence of association in order to yield an overall assessment of effectiveness. Evidence-based medicine seeks to achieve improved health outcomes by making evidence explicit and by developing explicit methods for evaluating it. To date, evidence-based medicine has largely focused on evidence of association produced by clinical studies. As such, it has tended to overlook evidence of pathophysiological mechanisms and evidence of the mechanisms of action of interventions. The book offers a useful guide for all those whose work involves evaluating evidence in the health sciences, including those who need to determine the effectiveness of health interventions and those who need to ascertain the effects of environmental exposures.

Schaechter's Mechanisms of Microbial Disease


Book Description

Now in full color, the Fourth Edition of this text gives students a thorough understanding of microbial agents and the pathophysiology of microbial diseases. The text facilitates learning and recall by emphasizing unifying principles and paradigms, rather than forcing students to memorize isolated facts by rote. Case studies with problem-solving questions give students insight into clinical applications of microbiology. Each chapter ends with review and USMLE-style questions. For this edition, all schematic illustrations have been re-rendered in full color and new illustrations have been added. A new online site for students includes animations, USMLE-style questions, and all schematic illustrations and photographs from the text.
