Histopathologists all over the world have to report cytopathology during the course of their work and it is then that they find themselves facing diagnostic dilemmas. This practical, well-illustrated book, explicitly dedicated to this readership will serve their needs and meets their requirements in daily practice.
Endometrial Pathology is a practical, clinically oriented reference on endometrial pathology. It is detailed enough for pathologists yet has a clinical focus that ensures its relevance and appeal to gynaecologists. The book covers the clinical aspects of evaluating the endometrium and the pathology of endometrial diseases, with differential diagnoses included as appropriate. There is a chapter on the histologic pitfalls in diagnosis and a final chapter on the latest information on molecular mechanisms and immunohistochemical tests.
This book is not intended as a general text on MRI. It is written as an intro duction to the field, for nonexperts. We present here a simple exposition of certain aspects of MRI that are important to understand to use this valuable diagnostic tool intelligently in a clinical setting. The basic principles are presented nonmathematically, using no equations and a minimum of symbols and abbreviations. For those requiring a deeper understanding of MRI, this book will help facilitate the transition to standard texts. Chapters 1 through 4 provide a general introduction to the phenomenon of nuclear magnetic resonance and how it is used in imaging. Chapter 1 discus ses magnetic resonance, using a compass needle as an example. In Chapter 2, the transition to the magnetic resonance of the atomic nucleus is made. Chapter 3 describes the principles of imaging. In Chapter 4, the terms T 1 and T 2 are described and their relationship to tissue characterization; the fun damental role of thermal magnetic noise in T 1 and T 2 is discussed."
In recent years there have been various discoveries connecting inflammation and lung cancer and clearly there is growing interest in this area of cancer research. The link between unresolved inflammation and cancer has been well established with estimates that 15% of cancer deaths are inflammation-related. Evidence for this link includes the following: a) some inflammatory diseases are associated with increased risk of cancer development; b) inflammatory mediators are present surrounding and within most tumors; c) overexpression of inflammatory cytokines increases cancer development and progression in murine studies; d) inhibition of inflammatory mediators decreases cancer development and progression; and e) the use of non-steroidal anti-inflammatory drugs (NSAIDs) has been found to decrease cancer incidence and delay progression. The volume will present aspects of the inflammatory tumor microenvironment (TME), its many roles in tumor progression and metastasis, including creation of a hypoxic environment, increased angiogenesis and invasion, changes in expression of micro-RNAs (miRNAs) and an increase in a stem cell phenotype. The book will also cover the mechanisms of inflammatory mediators. Chronic overexpression of inflammatory mediators in the TME, as seen in smokers and patients with non-small cell lung cancer (NSCLC), can also lead to increased tumor initiation, progression, invasion and metastasis. The volume will provide a comprehensive perspective of the latest findings and summaries of progress made regarding inflammation and its connection to lung cancer.
The genus Pseudomonas represents a large group of medically and envi ronmentally important bacteria. Interest in these bacteria is reflected in the extensive number of publications devoted to original research, re views, and books on this subject. In this volume selected areas of Pseu domonas research are presented in depth by persons who have been active in their fields over many years. The extensive reviews presented are an effort to provide a balanced perspective in a number of areas not readily available in the current literature. In the style of the previous Biotechnology Handbooks most of these topics have not been reviewed at all, and several are also presented from a new direction. For example, in addition to structural and compositional aspects, the chapter on lipids provides shifts in lipid parameters that result from environmental changes. This information will be invaluable to a cross section of Pseu domonas researchers in pathogenesis and bioremediation. The chapters presented include basic aspects of plasmid biology and carbohydrate metabolism and regulation. A major emphasis is placed on the Pseudomonas aeruginosa cell surface. Chapters cover lipo polysaccharide, capsular polysaccharide and alginate, the outer mem brane, transport systems, and the flagellum. Uptake of iron is also neces sarily an important portion of the chapter on iron metabolism."
To the uninitiated, the genus Clostridium is likely more to be associated with disease than biotechnology. In this volume, we have sought to remedy this misconception by compiling aseries of chapters which, together, provide a practically-oriented handbook of the biotechnologie potential of the genus. Clostridium is a broad grouping of organisms that together undertake a myriad of biocatalytic reactions. In the first two chapters, the reader is introduced to this diversity, both taxonomically and physiologically. In the following chapter, the current state of genetic analysis of members of the genus is reviewed. The remaining chapters concentrate on specific, exploit able aspects of individual Clostridium species-highlighting their range of unique capabilities (of potential or recognized industrial value), particu larly in the areas of biotransformation, enzymology, and the production of chemical fuels. Fittingly, the final chapter demonstrates that even the most toxic of the clostridia can be of therapeutic value. The contributors to this volume reflect the trans national interest in Clostridium, and we are indebted to each of them for making this volume possible. We particularly wish to acknowledge the contributions, both to this volume and to microbiology in general, of Dr. Elizabeth Cato, who, sadly, died shortly be fore publication ofthis volume. Finally, we would like to join the authors in recommending closer and wider consideration of the attributes and capabilities of this genus."
Genetically Modified and Irradiated Food: Controversial Issues: Facts versus Perceptions explains the technologies used in these processes so they can be understood by those in general public health, scientific organizations, politicians and opinion makers/policymakers.

Virus Variability and Impact on Epidemiology and Control of Diseases E. Kurstak and A. Hossain I. INTRODUCTION An important number of virus infections and their epidemic developments demonstrate that ineffec tiveness of prevention measures is often due to the mutation rate and variability of viruses (Kurstak et al., 1984, 1987). The new human immunodeficiency retroviruses and old influenza viruses are only one among several examples of virus variation that prevent, or make very difficult. the production of reliable vaccines. It could be stated that the most important factor limiting the effectiveness of vaccines against virus infections is apparently virus variation. Not much is, how ever, known about the factors influencing and responsible for the dramatically diverse patterns of virus variability. II. MUTATION RATE AND VARIABILITY OF HUMAN AND ANIMAL VIRUSES Mutation is undoubtedly the primary source of variation, and several reports in the literature suggest that extreme variability of some viruses may be a consequence of an unusually high mutation rate (Holland et al., 1982; Domingo et al., 1985; Smith and Inglis, 1987). The mutation rate of a virus is defined as the probability that during a single replication of the virus genome a particular nucleotide position is altered through substitution, deletion, insertion. or recombination. Different techniques have been utilized to measure virus mutation rates, and these have been noted in the extent of application to different viruses."

Authoritative investigators active in the discovery, development,
and application of biological anti-infective agents concisely
review their use and potential in preventing and treating human
disease. Focusing on biotherapeutic entities that have been tested
in controlled studies, the prominent experts illuminate the
scientific underpinnings of their therapeutic power, assess their
possible risks in the treatment of infectious diseases, and outline
the research needed to better define their effectiveness. In
addition, they also consider how biotherapeutic agents may be
genetically engineered for maximum intestinal and vaginal
production of bioactive substances in vivo. Biotherapeutic Agents
and Infectious Diseases brings together all the evidence needed to
understand and capitalize on the considerable promise of this
significant new class of biotherapeutic entities.
The Liver in Biology and Disease was conceived as a sequel in the
series "Principles of Medical Biology," whose general aim continues
to be the integration of human biology and molecular cell biology
into modern molecular medicine. It is a volume molded by the
Information Revolution which few will deny has forced the teaching
faculties in our medical schools to curtail and prune the teaching
load and focus on fundamentals and principles. With this intention
in mind, a volume of this nature takes into account the close
dependence of progress in the medical sciences on bioinformatics
(gene and protein analysis) or more precisely, computational
biology and of course, the Internet. In general, it follows the
pattern of its predecessors.
The ability to remember an antigenic encounter for several decades, even for a life time, is one of the fundamental properties of the immune system. This phenomenon known as "immunological memory," is the foundation upon which the concept if vaccination rests. Therefore, understanding the mechanisms by which immunological memory is regulated is of paramount importance. Recent advances in immunology, particularly in the field of innate immunity, suggest that the innate immune system plays fundamental roles in influencing immunological memory. Indeed, emerging evidence suggests that events that occur early, within hours if not minutes of pathogen or vaccine entry profoundly shape the quantity, quality and duration of immunological memory. The present volume assembles a collection of essays from leading experts that span the entire spectrum research from understanding the molecular mechanisms of innate immune recognition, to dendritic cell function, to the generation and maintenance of antigen-specific B and T-cell responses.
Years ago when we were asked to write a book on the present-day knowledge of the molecular biology of poliovirus, we did not expect that such an apparently simple task could involve so much time and effort. Our writing was hampered by the fact that both of us are full time "workers," so that this monograph is mainly a spare time expedience. The main attention of this book focuses on a detailed review of the molecular biology of poliovirus and especially on the advances of the last decade; medical and environmental aspects are only briefly mentioned. Observations from older studies are considered in view of more recent information. Some of the older ob servations provided fundamental insights and paved the way for present day research; too often such data has been neglected or independently rediscovered. Today, poliovirus research has again attracted considerable interest. High points gained within the last few years were the elucidation of the complete nucleotide sequences of the RNAs of the three poliovinls serotypes and the corresponding vaccine strains, the demonstration of genome evolution during transmission of poliovirus in an epidemic, further characterization of the antigenic sites on the virus particle and of the antigenic drift, characterization of alternate conforma tional states of the virion capsid, the development of monoclonal antibodies against some of the virus proteins, observations on the role of the plasma membrane, cytoskeleton, and cytoplasmic membranes as mediators in the virus induced redirection of the synthetic machinery of the host cell, and characteriza"
