White blood cells, or leukocytes are cells of the immune system involved in defending the body against both infectious disease and foreign materials. Five different and diverse types of leukocytes exist, but they are all produced and derived from a multipotent cell in the bone marrow known as a hematopoietic stem cell. They live for about 3 to 4 days in the average human body. In this book, the authors present current research in the study of the biology, classification and role in disease of leukocytes. Topics include an analysis of peptides and proteins isolated from alligator leukocytes; modification of immune cell activity by neuroendocrine mediators and development of disease; congenital defects of phagocytes; leukocyte mitochondrial membrane potential in type 1 diabetes; biology of human myeloid dendritic cells; and the leukocyte expression of CD36 as a biomarker for Alzheimer's disease.

The format of Essential Human Histology departs considerably from that of the usual presentations on human tissue/organ biology. This presentation was not designed as a formal reference textbook but as a tool solely for students and is designed for rapid student learning as well as rapid review in preparation for USMLE examinations. Essential Human Histology focuses the beginning student's attention on the most important aspects of this discipline which are presented as a series of learning units. In general, the text follows the traditional and logical sequence of cells to tissues to organs, but within this sequence, the discussion on mitosis is presented immediately after the cell and discussion on meiosis just prior to a consideration of the reproductive systems. To understand human structural biology, it is essential to learn a specialized vocabulary and to assimilate a large body of facts. Learning, as distinct from memorization, depends to a great degree on repetition and reinforcement and is made easier if the material to be learned can be presented in discrete, manageable segments. these requirements and, if used properly, will enable the student to master this knowledge quickly and efficiently. The Uses of this Textbook are: The subject matter is broken down into small learning units, each of which is introduced by a vocabulary appropriate to that unit. The vocabulary introduces the main features of the subject to be discussed and provides the basic vocabulary for that unit. As each segment is read, note the vocabulary words (identified by bold print) in the text and how they contribute to the discussion. After completing the narrative segment, return to the vocabulary words, using them as prompts to recall the details of the material just read. The vocabulary serves as a summary of the topic and provides a means for rapid review. If a vocabulary word fails to prompt a response, it and the associated text can be found quickly from the bold type in the appropriate segment. introduction into the development of each tissue and/or organ and provides another means of reinforcement that contributes to an overall understanding of the tissue or organ being considered. Summaries briefly outline the structural/functional relationships and serve to draw the information together and to provide an additional review of the topic. During preparation of Essential Human Histology, three major considerations were kept in mind: most curricula place considerable time constraints on the student; function and structure are inextricably related; and the learning process essentially is a matter of repetition and reinforcement. The narrative strives to present the vast amount of information available on this topic, in a concise and logical manner, without sacrificing the detail that is necessary for a basic understanding of human tissue and organ biology.

The examination and interpretation of tissue sections seen under the light microscope in a laboratory setting is an example of student-directed, independent problem solving. The proper reading of a histologic section is an acquired art that can only be developed through practice, close observation and repetition. This laboratory manual was designed as a guide for students to aid them in this endeavor. The laboratory study guide/manual was designed to be used as a supplement to any current textbook and/or atlas of Histology. Learning objectives provide the overall goals for each chapter. The narrative of the study guide explains how to systematically breakdown, examine and interpret each tissue and/or organ encountered, without regard to a given histologic slide from a specific slide collection. Thus, this systematic method can be used to examine and interpret histologic preparations from any collection or of any species. The student is encouraged to sketch, label and create a personalized atlas while using this laboratory manual as a guide. The vocabulary that should be developed and used during the laboratory can be found quickly by going to the bold face type in the appropriate segment of the text. Each chapter contains one or more tables in which key structures used in the identification of a tissue/organ are presented, offering the briefest possible summary of important histologic features. As a final short review, an appendix provides summary tables that compare and contrasts the basic differences of several structures that are somewhat similar in general architecture.

"In this provocative ethnography, Hogle reveals how the uses of human tissue and organs as therapeutic agents are intimately related not only to expanding arenas of commodification, but also to the politics of nationalism. A challenge to received wisdom about bodies and persons."-Margaret Lock, author of Encounters with Aging: Mythologies of Menopause in Japan and North America "This astonishing portrait of changing understandings of life and death is both profound and revolutionary. While extending classical debates about body parts as gifts and as commodities, it brilliantly transfigures them. Unparalleled in its field, this powerful book redefines the future of medical anthropology."-Sarah Franklin, Reader in Cultural Anthropology, Lancaster University (England) The body is both a site for medical practice and a source of tools for therapeutic and scientific uses. There are many meanings ascribed to the body that both affect and are affected by numerous cultural, economic, political and legal issues. In order to procure and use body organs and tissues, Linda F. Hogle states, scientists enlist a wide array of cultural assumptions. Nowhere is this more evident than in present-day Germany, where the specter of Nazi medical experimentation still plays a large role in national policies governing treatment of both living and dead bodies and the way these policies are put into practice. In their efforts to distance themselves from the atrocities of the past, German medical practitioners and policy-makers have reformulated ideas of bodily violation. Furthermore, the reunification of East and West Germany has engendered new questions about the relationship between individuals' bodies, science, and the state. Recovering the Nation's Body is the first book to analyze the actual practices involved in procuring human body parts, and the first to examine how the German past and the unique present-day situation within the European Union are keys to understanding the forms that medical practice takes within various cultural contexts. Linda F. Hogle is a fellow at the Stanford University Center for Biomedical Ethics. She has written widely on the anthropology of science and on bioethics and cultural diversity.

This manual presents a wide variety of techniques associated with the use of human CNS tissue obtained at autopsy. The book contains detailed methodologies in discrete chapters written by an expert in the specific field. In addition, it addresses the potential for interactions between molecular studies in brain tissue obtained at autopsy and living brain by using neuroimaging techniques, and directs to reader to suppliers of equipment and reagents that have been shown to be useful when studying human brain tissue.;Topics include problems of collecting brain tissue at autopsy, how psychiatric diagnosis can be made after death and specific problems faced in using human brain tissue in modern laboratory-based techniques.;Suitable for all those using human tissue in their research, this manual is of particular value to those commencing studies using brain tissue. those involved in the study of brain tissue in an attempts to understand molecular and cellular changes that underlie psychiatric illnesses will find it invaluable.

In the human body, collagen is the most abundant structural protein, forming up to 35% of the entire protein content of the whole body. In this book, the preparation, characterization and applications in tissue regeneration of bovine type 1 collagen are reviewed. Furthermore, collagen is often used in regenerative medicine. In this book, the authors report on the helicity of collagen molecule in fibrils by circular dichroism spectroscopy and the thermograph of fibrils by differential scanning calorimetry (the structural aspects of collagen molecules). In the last chapter, second harmonic generation (SHG) microscopy is reviewed and its potential to visualize collagen fibers in a variety of connective tissues.

Each volume in this richly illustrated series, published in association with the Papanicolaou Society of Cytopathology, provides an organ-based approach to the cytological and histological diagnosis of small tissue samples. Benign, pre-malignant and malignant entities are presented in a well-organized and standardized format, with high-resolution color photomicrographs, tables, and lists of key specific morphologic criteria. Example vignettes allow the reader to assimilate the diagnostic principles in a case-based format. This volume provides comprehensive coverage of both surgical pathology and cytopathology of breast lesions. With a focus on malignant tumors, the full spectrum of inflammatory disorders, benign lesions, and hyperplasias are also covered in detail. Advantages and disadvantages of aspiration and core biopsy are discussed, as well as ancillary testing such as hormonal and molecular markers. With over 500 printed photomicrographs and a CD-ROM offering all images in a downloadable format, this is an important resource for all anatomic pathologists.

A person's body fat percentage is the total weight of the person's fat divided by the person's weight and consists of essential body fat and storage body fat. Essential body fat is necessary to maintain life and reproductive functions. In this book, the authors present current research in the composition, measurement and reduction procedures of body fat. Topics discussed include body composition measurements; MSG intake suppresses caloric intake, weight gain, and fat deposition in female rats; body mass index and fat distribution among circumpolar people; and, body fat in individuals with Down Syndrome and adipsin as a new biomarker of body fat distribution.
