Red blood cells in humans—and most other mammals—have a tendency to form aggregates with a characteristic face-to-face morphology, similar to a stack of coins. Known as rouleaux, these aggregates are a normally occurring phenomenon and have a major impact on blood rheology. What is the underlying mechanism that produces this pattern? Does this really happen in blood circulation? And do these rouleaux formations have a useful function? The first book to offer a comprehensive review of the subject, Red Blood Cell Aggregation tackles these and other questions related to red blood cell (RBC) aggregates. The book covers basic, clinical, and physiological aspects of this important biophysical phenomenon and integrates these areas with concepts in bioengineering. It brings together state-of-the-art research on the determinants, mechanisms, and measurement and effects of RBC aggregation as well as on variations and comparative aspects. After an introductory overview, the book outlines factors and conditions that affect RBC aggregation. It presents the two hypotheses—the bridging model and the depletion model—that provide potential mechanisms for the adhesive forces that lead to the regular packing of the cells in rouleaux formations. The book also reviews the methods used to quantify RBC aggregation in vitro, focusing on their importance in clinical practice. Chapters discuss the effect of RBC aggregation on the in vitro rheology of blood as well as on tube flow. The book also looks at what happens in the circulation when red blood cells aggregate and examines variations due to physiological and pathophysiological challenges. The concluding chapter explores the formation of red blood cell aggregates in other mammals. Written by leading researchers in the field, this is an invaluable resource for basic science, medical, and clinical researchers; graduate students; and clinicians interested in mammalian red blood cells.

The ISOTT 2001 local organizing committee was pleased to welcome over 140 delegates from around the world to the 29th annual general meeting of the International Society for Oxygen Transport to Tissue. The meeting was held in historic Philadelphia, USA, on the campus of the University of Pennsylvania from August 11 to 15, 2001. In the tradition of ISOTT, the conference was a total immersion experience. Attendees were encouraged to eat together and spend their evenings relaxing together in a style that maximized exchange of ideas and interactions of younger scientists with their more senior colleagues. Delegates participated in a total of 122 presentations including poster displays, selected oral presentations, seminars by invited speakers and a round table discussion. In choosing invited speakers and oral presenters, special emphasis was placed on methods for oxygen measurement in living tissue and application of these technologies to understanding physiological and biochemical basis for pathology related to tissue oxygenation. All of the manuscripts contained in this volume underwent both an editorial and scientific review, and only those meeting both criteria have been published. However, while all efforts have been made to eliminate editorial errors, some have undoubtedly been overlooked, for which the editors apologize.

Using a case-based approach, it richly depicts a full range of retina and macular diseases, including new infectious, degenerative, and dystrophic conditions. Take advantage of the latest imaging technologies to identify common and rare disorders, and confirm difficult diagnoses with the aid of more than 5,500 high-quality images. Printed in full color for the first time, this edition is accessible online at www.expertconsult.com. "... appropriate for highly ambitious residents, retina fellows and specialists, and general ophthalmologists who are looking for an excellent reference book with a proud lineage and impeccable reputation." Reviewed by ESCRS EuroTimes (European Society of Cataract and Refractive Surgery), Apr 2015 Rely on the same unique, richly illustrated case-descriptive format-encompassing history, clinical examination, and follow-up-that popularized the original book by the late Dr. Donald Gass, the famed ophthalmologist whose clinical expertise set new standards in macular diagnosis. Get expert diagnostic guidance under the new authorship of Dr. Anita Agarwal, a protégé of Dr. Gass who has compiled the ultimate collection of images and hard-to-find case studies. Evaluate macular diseases using the latest techniques including fluorescein angiography, optical coherence tomography (OCT), indocyanine green (ICG), and fundus autofluorescence. Visualize the conditions you're likely to see in practice and confirm your diagnoses by comparing your clinical findings to more than 5,500 images and illustrations (over 3,500 in full color).

Transfusion Medicine and Scientific Developments focuses on unknown aspects of blood cells and transfusion practice. Blood transfusion medicine has become a sophisticated and specialized field of medicine. Some aspects will be discussed in this book. The book has been divided into three sections. The first section includes chapters describing the immunological and coagulation-assisting functions of red blood cells and methods to measure their life span. The second section discusses the role of platelets in inflammatory processes. The third section reviews functional dose of RBC transfusions and transfusion practice in various clinical settings.

Expertly edited and endorsed by the International Society for Laboratory Hematology, this is the newest international textbook on all aspects of laboratory hematology. Covering both traditional and cutting-edge hematology laboratory technology this book emphasizes international recommendations for testing practices. Illustrative case studies on how technology can be used in patient diagnosis are included. Laboratory Hematology Practice is an invaluable resource for all those working in the field.

The task the editors have set themselves is to survey the field of clinical hemorheology from basic principles to up-to-date research. It is only in a new science like this that it is possible to span the whole field in a book of this size. Hemorheology, as a new approach to the study and management of a wide range of circulatory diseases, is now beginning to appear with increasing frequency in general as well as specialized medical journals. Hemorheology is also just beginning to creep into the undergraduate medical curriculum. Therefore, the majority of graduate doctors are unequipped to assess the place of hemorheology in the overall framework of circulatory physiology and pathology or to assess its relevance to their everyday practice. It is hoped that this book will fill this gap. The approach of the book is interdisciplinary. The first part deals with basic principles of blood flow, circulation and hemorheology. It has been written with the general doctor in mind, who has no special knowledge of hemodynamics and rheological concepts, terminology or methodology. To maintain the emphasis on practical clinical applications, all the chapters in the second part of the book have been written by clinical specialists practicing in the individual areas of disease. The book is so designed that clinicians may be able to read the relevant chapters in the second part of the book in isolation, using the basic science aspects contained in the first part of the book as reference chapters.

Published in 1988: Study of blood flow properties (rheology) has attracted growing interest from clinicians in recent years. A United Kingdom meeting and a European meeting in 1979 resulted in previous publications summarizing the literature up to that time.
