Beyond Brain Death offers a provocative challenge to one of the most widely accepted conclusions of contemporary bioethics: the position that brain death marks the death of the human person. Eleven chapters by physicians, philosophers, and theologians present the case against brain-based criteria for human death. Each author believes that this position calls into question the moral acceptability of the transplantation of unpaired vital organs from brain-dead patients who have continuing function of the circulatory system. One strength of the book is its international approach to the question: contributors are from the United States, the United Kingdom, Liechtenstein, and Japan. This book will appeal to a wide audience, including physicians and other health care professionals, philosophers, theologians, medical sociologists, and social workers.

Although there have been many books on HIV and AIDS, surprisingly little has been published that focuses on the immunology of retroviral infections in general, and HIV in particular. Retroviral Immunology: Immune Response and Restoration is the first book of its kind to address the most important aspects of the immunology of retroviruses, including not only the virus-specific immune responses, but also genetic and virologic factors modulating these responses. The book also deals directly with the emerging concept of immune restora tion in retroviral infections, a particularly important subject to the thousands of clinicians who deal with this problem on a daily basis. With the advent of highly effective antiviral drug regimens to slow down the replication of HIV and the progression of AIDS, new challenges and opportunities are arising. Restoration of general immune function has brought with it not only complica tions of immune restoration-mediated disease, but also the realistic hope for meaningful restoration of the ability to control HIV replication with the immune system. Leading scientists in the field have summarized the most current informa tion regarding experimental and clinical aspects of retroviral infections. Retroviral Immunology: Immune Response and Restoration should prove an impor tant point of reference for basic scientists and clinicians in this area of research. We are indebted to all of our authors for their excellent contributions."

A thorough review of general mathematics and its applications in radiography as well as a handy reference for basic formulas and calculations used by radiographers. This book starts with basic mathematic principles and moves on to present the reader with the calculations required to produce high quality radiographic images and practice problems which aid in the understanding of these calculations. Areas discussed include mAs conversions, inverse square law, radiographic density and contrast, screens and grid ratios, grid conversions, geometric and magnification unsharpness, and graphs and conversions between conventional and systems international (SI) units of radiation dosimetry. No other book provides such clear instruction for radiographic calculations. A handy Instructor's Manual is also available.

Pathogenic bacteria for human and animals have developed sophisticated weapons, termed virulence factors, to ensure their replication and persistence into their hosts. The authors in this volume show a synthesis on how the various host cellular Rho GTPases activities are manipulated by bacteria to fulfil their virulence.

Helicobacter pylori is an important human pathogen that infects up to 50% of the human population. As the leading cause of peptic ulcers, gastritis, and gastric cancer worldwide, the organism has been the subject of intensive research to unravel the mysteries of its genetics and cellular biology. In fact, the number of publications in this field has risen dramatically in recent years making it extremely difficult for even the most diligent reader to stay abreast of progress. This book distills the most important cutting-edge findings in the field to produce a timely and comprehensive review. With contributions from leading international helicobacter researchers, topics include: lipopolysaccharides, outer membrane proteins, motility and chemotaxis, type IV secretions systems, metal metabolism, molecular mechanisms of host adaptation, genomotyping, and proteonomics. As a useful introduction to the subject for new researchers and as an invaluable reference for the experienced researcher, this book is essential reading for all researchers working with Helicobacter and related organisms.

In contrast to the substantial literature that focuses upon innate immune signaling in the gut, there is remarkably less known about the response of the airway to bacterial pathogens. The purpose of this book will be to review the current status of theunderstanding of the pathogenesis of acute bacterial pneumonia, slanted toward the mucosal immunology of these infections. It will describe, in general, the signaling cascades that control the proinflammatory response to bacterial infection in the lung. How innate immune signaling is orchestrated in response to specific common airway pathogens is addressed, targeting Staphylococus aureus (including MRSA), Streptococcus pneumoniae and Klebsiella pneumoniae. By describing the general immunological responses to conserved bacterial components and then detailing how specific organisms cause infection, this book provides a targeted but comprehensive review of this important topic.

The aim of this book is to provide readers with a wide overview of the main healthcare-associated infections caused by bacteria and fungi able to grow as biofilm. The recently acquired knowledge on the pivotal role played by biofilm-growing microorganisms in healthcare-related infections has given a new dynamic to detection, prevention and treatment of these infections in patients admitted to both acute care hospitals and long-term care facilities. Clinicians, hygienists and microbiologists will be updated by leading scientists on the state-of-art of biofilm-based infections and on the most innovative strategies for prevention and treatment of these infections, often caused by emerging multidrug-resistant biofilm-growing microorganisms.

This book provides a comprehensive overview of metabonomics and gut microbiota research from molecular analysis to population-based global health considerations. The topics include the discussion of the applications in relation to metabonomics and gut microbiota in nutritional research, in health and disease and a review of future therapeutical, nutraceutical and clinical applications. It also examines the translatability of systems biology approaches into applied clinical research and to patient health and nutrition. The rise in multifactorial disorders, the lack of understanding of the molecular processes at play and the needs for disease prediction in asymptomatic conditions are some of the many questions that system biology approaches are well suited to address. Achieving this goal lies in our ability to model and understand the complex web of interactions between genetics, metabolism, environmental factors and gut microbiota. Being the most densely populated microbial ecosystem on earth, gut microbiota co-evolved as a key component of human biology, essentially extending the physiological definition of humans. Major advances in microbiome research have shown that the contribution of the intestinal microbiota to the overall health status of the host has been so far underestimated. Human host gut microbial interaction is one of the most significant human health considerations of the present day with relevance for both prevention of disease via microbiota-oriented environmental protection as well as strategies for new therapeutic approaches using microbiota as targets and/or biomarkers. In many aspects, humans are not a complete and fully healthy organism without their appropriate microbiological components. Increasingly, scientific evidence identifies gut microbiota as a key biological interface between human genetics and environmental conditions encompassing nutrition. Microbiota dysbiosis or variation in metabolic activity has been associated with metabolic deregulation (e.g. obesity, inflammatory bowel disease), disease risk factor (e.g. coronary heart disease) and even the aetiology of various pathologies (e.g. autism, cancer), although causal role into impaired metabolism still needs to be established. Metabonomics and Gut Microbiota in Nutrition and Disease serves as a handbook for postgraduate students, researchers in life sciences or health sciences, scientists in academic and industrial environments working in application areas as diverse as health, disease, nutrition, microbial research and human clinical medicine.

Organs and tissues that can tolerate little or no inflammation have developed multiple overlapping mechanisms of immune protection in the absence of inflammation. These areas have been designated immune-privileged sites by Peter Medawar and include the central nervous system, eye, reproductive tract, testis and possibly the liver. Mechanisms of immune homeostasis found in less immune-regulated organs are often evident in the immune privileged sites and vice versa. It is important that the non-inflammatory mechanisms that contribute to immune privilege allow host defense against infectious organisms.

This volume highlights the mechanisms leading to immune privilege in tissues and organs, the deviation of immune responses and the modification of the behavior of the immune cells that manage to cross the blood barriers of tissues, in the context of infection.

t Heinz Red! and Gunther Sch!ag Ludwig Boltzmann Institute for Experimental and Clinical Traumatology, Vienna, Austria The word "sepsis" derives from the Greek meaning decay or rottenness. Tradition ally this term has been used to describe the process of infection accompanied by the host's systemic inflammatory response. Based on that understanding, previous clin ical studies have been designed to include only patients with positive blood cultures [1, 2]. However, the frequent occurrence of a septic response without the demon stration of microorganisms in the circulation has led to a new definition and under standing of sepsis, mainly as the systemic response of the host to an often unde tectable microbiological or non-microbiological process [3]. The general consensus is that cytokines are central to the inflammatory response, particularly in sepsis. It is now known that not only Gram-negative but also Gram positive, viral, and fungal infections initiate the complex cascades of cytokine release. Probably the most important aspect of bacterial action is the release of toxic bacterial products. In particular endotoxin from Gram-negative bacteria (see chap ter by Schade) and super antigens (see chapter by Neumann and Holzmann), as well as pore-forming toxins [4] from Gram-positive bacteria, induce cytokine formation. The importance of this cytokine release is evident from both diagnostic and thera peutic (mostly experimental) studies, and the action of cytokines may be the key to our understanding of the pathophysiology of the sepsis syndrome.

A grand summary and synthesis of the tremendous amount of data now available in the post genomic era on the structural features, architecture, and evolution of the human genome. The authors demonstrate how such architectural features may be important to both evolution and to explaining the susceptibility to those DNA rearrangements associated with disease. Technologies to assay for such structural variation of the human genome and to model genomic disorders in mice are also presented. Two appendices detail the genomic disorders, providing genomic features at the locus undergoing rearrangement, their clinical features, and frequency of detection.

Structure-Function Relationships of Human Pathogenic Viruses provides information on the mechanisms by which viruses enter the cell, replicate, package their DNA into capsids and mature into new virions. The relation between structural features and the pathogenicity and oncogenicity of some of the most relevant human viral pathogens are demonstrated and the acquisition of defense mechanisms through virus-host interactions are presented. In contrast to textbooks, this volume combines timely research data to provide a holistic view of viral pathogenesis.

Furthermore Structure-Function Relationships of Human Pathogenic Viruses illustrates in a single volume the fundamental processes involved in viral life cycles using up-to-date information from research laboratories around the world. Knowledge of these processes is crucial to develop rationales for the design of future drugs. The timeliness of the data and the comprehensive yet concise approach this book takes in order to present the world of viral pathogens should make it a frontrunner in higher education and R&D.

For decades it has been known that structured conformations are important for the proper functioning of most cellular proteins. However, appreciation that protein folding to the functional conformations as well as the structural maintenance of protein molecules are very complex processes has only emerged during the last ten years. The intimate interplay uncovered by this scientific development led us to realize that perturbations of the protein folding process and disturbances of conformational maintenance are major disease mechanisms. This development has given rise to the concept of conformational diseases and the broader signature of protein folding diseases, comprising diseases in which mutations or environmental stresses may result in a partial misfolding that leads then to alternative conformations capable of disturbing cellular processes. This may happen by self-association (aggregation), as in prion and Alzheimer s diseases, or by incorporation of alternatively folded subunits into structural entities, as in collagen diseases. Another possibility is that folding to the native structure is impaired or abolished, resulting in decreased stea- state levels of the correctly folded protein, as is observed in cystic fibrosis and 1-antitrypsin deficiency, as well as in many enzyme deficiencies. In addition, deficiencies of proteins that are engaged in assisting and supervising protein folding (protein quality control) may impair the folding of many other proteins, resulting in pathological phenotypes. Examples of this are the spastic paraplegia attributable to mutations in mitochondrial protease/chaperone complexes."

Leading researchers and clinicians join forces to explain how malignant melanoma develops from its benign precursor cell type. The authors focus on the molecular mechanisms involved in melanogenesis, in the malignant transformation of melanocytes, and in the further progression of primary melanomas into invasive and metastatic melanomas. They also review recent advances in our understanding of the basic biology of melanocytes and the development, migration, and differentiation of melanoblasts into melanocytes. The book provides an up-to-date understanding of the progressive mechanisms of oncological development in malignant melanoma, a likely model of malignant progress for other types of cancer, and the ongoing development of novel therapeutics.

Since the initial establishment of Robert Koch's postulates in the nineteenth century, microbial protein toxins have been recognized as a major factor of bacterial and fungal virulence. An increasing number of proteins produced and secreted by various bacteria, yeasts and plants are extremely toxic and most of them developed remarkably "intelligent" strategies to enter, to penetrate and to finally kill a eukaryotic target cell by modifying or blocking essential cellular components.

This book describes the strategies employed by protein toxins to render their pro- and eukaryotic producers a selective growth advantage over competitors. In providing an up-to-date overview on the mode of protein toxin actions, it accommodates biomedically and biologically relevant toxin model systems. As a result, it significantly broadens our perspective on biochemical architecture and molecular ploy behind the lethal principles of pro- and eukaryotic toxins.

The staphylococci are important pathogenic bacteria responsible for a variety of diseases in humans and other animals. They are the most common cause of hospital-acquired infection. Antibiotic resistant strains (MRSA) have become endemic in hospitals in most countries, causing major public health issues. In addition, the incidence of new strains that cause severe community-acquired infections in healthy people is increasing and MRSA strains are emerging in agricultural and domestic animals. In the race to understand staphylococcal pathogenesis, the focus has been on genetics, as a bacterium can only do what its genes allow. The publication of the first staphylococcal whole genome sequence in 2001 paved the way for a greater understanding of the molecular basis of its virulence, evolution, epidemiology, and drug resistance. Since then, the available genomic data has mushroomed and this, coupled with the major advances in genetic know-how and the availability of better genetic tools, has

I assume that you already know a good deal of microbiology. In this book, I frequently use the word "we" by which I mean "you and I." Together we are going to consider bacteriology from a broader perspective and we will think our way through the important biological problems that are frequently just skipped over in every microbiology course. My most important reason for writing this book is to make accessible the relevant thinking from fields of science other than microbiology that are important to microbiology. The book is written for people that have already have a fascination with bacteria, but can see that their background for understanding is far complete. This book consists of topics that are largely omitted from microbiology textbooks and includes some mathematics, physics, chemistry, and evolutionary biology. It contains a good deal of my own work, both experimental and theoretical, together with a lot of speculation. If ten times bigger, it would be a full text book on microbial physiology. A third of the microbial physiology is covered by the recent is no longer treated even in textbook by White (2000). Another third current specialized tests and is greatly underrepresented in text books.

This volume aims to enhance the current understanding of clinical features, treatment and pathogenic aspects in necrotizing soft tissue infections. Various representative case studies are discussed to enhance the readers' understanding of these complex diseases. Necrotizing soft tissue infections are rapidly spreading infections that may cause extensive soft tissue or limb loss, multiorgan failure and are associated with a considerable fatality rate. It is undisputed that rapid diagnosis and prompt intervention is directly related to survival. The initial presentation may be limited to unspecific symptoms such as tenderness, swelling, erythema and pain. Thus, diagnosis and management are challenging due to heterogeneity in clinical presentation, in co-morbidities, in microbiological aetiology, as well as in the pathogenic mechanisms. An international and multidisciplinary consortium, INFECT, has for the last 6 years been pursuing research aimed to advance the understanding of the clinical and pathogenic aspects of these infections. A central part has been to create a comprehensive clinical registry and associated biobank which have also formed the basis for the experimental studies. Using the INFECT patient cohort, as well as an integrated systems biology approach in patients and clinically relevant experimental models, an advanced insight of diagnostic features, causative microbial agents, treatment strategies, and pathogenic mechanisms (host and bacterial disease traits and their underlying interaction network) has been obtained.
