Although virology and immunology are now considered separate disciplines, history shows that these areas ofinvestigation always overlapped and one cannot really exist without the other. This trend has become particularly significant and fruitful in the past few years in the area of herpesvirus research. The genomes of the most important herpesviruses have been sequenced, a significant portion of their genes have been identified, and many secrets of regulation of gene expr- sion have been unraveled. Now this progress sets the stage for a true revolution in herpesvirus research: analysis of interactions between the host and the virus. Because herpesviruses can induce, suppress, and fool the immune system, the most productive herpesvirologists are also expert immunologists, and the current results ofthis interdisciplinary effort are truly remarkable. Because herpesviruses cause many important human diseases, the devel- ment of vaccines against these agents is a very significant goal. This effort is also very challenging because of the complexity of herpesviruses and the lack of sufficient information about immune responses. The remarkable ability of herpesviruses to escape immune responses is - other feature that brings immunology and virology together. Herpesviruses - code many proteins that interact with and down-regulate some key elements of the immune system. Thisproperty of herpesviruses represents amajor challenge in developing strategies against these viruses. On the positive side, these viral proteins also provide novel tools for analyzing specific immune reactions and molecular mechanisms.
This is the most comprehensive, up-to-date reference on this post-translational modification of proteins, which is intimately linked with DNA repair, maintenance of genomic stability, transcriptional regulation, cell death and a variety of other cellular phenomena as well as with a variety of pathophysiological conditions, including ischemia-reperfusion damage, Parkinson 's disease, Type I diabetes mellitus, hemorrhagic and septic shock and other inflammatory conditions. Richly illustrated, it offers 19 chapters written by international experts.
Alessandro Condivilla of Bologna first attempted a resection of the head of the pan creas in 1898, but several decades of further trial-and-error attempts ensued before the prototype procedure of pancreatoduodenectomy (PD) was established by Whipple in 1935. In the half-century following that landmark, refinements of surgical technique, including pancreatico-and bilio-entero anastomosis as well as develop ment of new technology to support perioperative management and patient care have contributed to the decrease in mortality and morbidity rates for obstructive jaundice and pancreatic fistula. The improvement in mortality and morbidity rates associated with PD has led to an increase in the number of patients undergoing the procedure and in the number of institutions performing it. Indications for PD have also been expanded. In the early years after PD was established as a viable procedure, periampullary carcinoma was the most common indication; now PD is indicated for a number of benign and malignant diseases. Some surgeons believe that PD is the procedure of choice for certain types of chronic pancreatitis, pancreatico-biliary maljunction, and pancreatic and duodenal trauma. Other surgeons have reported the necessity of PD for lymph node dissection of gallbladder carcinoma. Consequently, the basic procedure has been greatly modi fied to accommodate the specific conditions of each disease. For patients with malig nancy, extended procedures have been developed to improve the curative resection rate and ensure complete lymph node dissection.
This book describes antibiotic resistance amongst pathogenic bacteria. It starts with an overview of the erosion of the efficacy of antibiotics by resistance and the decrease in the rate of replacement of redundant compounds. The origins of antibiotic resistance are then described. It is proposed that there is a large bacterial resistome which is a collection of all resistance genes and their precursors in both pathogenic and non-pathogenic bacteria. Ongoing resistance surveillance programs are also discussed, together with the perspective of a clinical microbiologist. The book then turns to specific themes such as the most serious area of resistance in pathogens, namely in Gram-negative organisms. The role of combinations of antibiotics in combating resistance emergence is discussed, particularly in the tuberculosis field, and then the importance of non-multiplying and persistent bacteria which are phenotypically resistant to antibiotics and prolong the duration of therapy of antibiotics which leads to poor compliance and resistance emergence. The role of anti-microbial compounds in textiles is covered, with its potential to exacerbate the spread of resistance. Then, efflux pumps are discussed. The final chapter describes the compounds which are in late stage clinical development, illustrating the paucity of the antibiotic pipeline, especially for Gram-negative bacteria.
This book covers lymphoproliferative disorders in patients with congenital or acquired immunodeficiencies. Acquired immunodeficiencies are caused by infections with the human immunodeficiency virus or arise following immunosuppressive therapy administered after organ transplantation or to treat connective tissue diseases such as rheumatoid arthritis. It was recently discovered that various diseases or therapeutic modalities that induce a state of immunosuppression may cause virally driven lymphoproliferations. This book summarizes for the first time this group of immunodeficiency-associated lymphoproliferations.
There is a widespread consensus that use of antioxidants as a therapeutic approach may counteract free radical mediated pathologies. However, the role of antioxidants in normal physiology and redox signaling is still in its infancy. Since oxidative stress is related to various diseases and pathologies, scientists are eager to study the disease in humans, but it is not always ethical to study all the aspects of the disease in humans. Thus, it becomes mandatory to study the disease process and the mechanisms behind it through experimental models which generally involve animals, in vitro/cell culture studies, primates and even humans to a certain extent. Studies on Experimental Models contains data on the experimental models or review of such models of oxidative stress in various diseases. It is structured into six sections, which are as follows: diabetes, cardiovascular, neurology, ocular diseases, toxicology/environmental and in vitro/tissue culture. Each section presents a sketch of models in humans, animals and in vitro methods. Taken together, they comprise a valuable reference for basic and clinical scientists, one aimed at contributing to the advancement of oxidative stress research using appropriate animal models.
This collection of translations of some of Koch's important essays represents an important first. It includes three of his essays on anthrax, three on tuberculosis, two on cholera, one on wound infections, and a relective essay entitled "On Bacteriological Research." These papers clearly reflect the coherence and inter-connectedness of Koch's thought. They include the initial presentation of his ideas and also provide examples of his tenacious and devasting responses to his critics. While they only represent some of the many areas of Koch's interests, they serve as excellent samples of his finest contributions. The volume also includes a long introduction which establishes the historical context of Koch's work and of the particular essays translated here.
Conceptually unsavoury, airway mucus is vital to homeostasis in the respiratory tract. In contrast, when abnormal, mucus contributes significantly to the pathophysiology of a number of severe bronchial diseases, including asthma, chronic bronchitis and cystic fibrosis. This volume provides wide ranging and in-depth coverage of the scientific and clinical aspects of airway mucus. It commences with introductory chapters which address the biochemical and molecular biological basis of airway mucus and continues with comprehensive coverage of the various physiological and rheological aspects of respiratory secretions. The clinical aspects of the topic are then considered, with chapters discussing the involvement of mucus secretions in bacterial infection and in hypersecretory diseases of the airway. The volume concludes with a discussion of the therapeutic aspects of the topic, both in terms of the possible approaches to the treatment of mucus hypersecretion and the interaction of these drugs with airway mucus. Written by leading experts in the field, each contribution provides a comprehensive review of its particular subject. Reflecting the latest advances in this important area of respiratory research, this volume will be of great interest to scientists and clinicians working in the field of airway secretions and related areas.

Scientists often look askance at their colleagues whose research appears too strongly focused on a single gene or gene product. We are supposed to be interested in the "big picture" and excessive zeal in pursuit of a single pixel might seem to border on an obsession that is likely to yield only details. However as this volume of Current Topics in Microbiology and Immunology demonstrates, this is certainly not the case for myc. Intense study of this en- matic proto-oncogene over the last twenty years has only broadened our view of its functions and led to insights into mechanisms relating to transcriptional regulation as well as to cell growth, proliferation, differentiation, apoptosis and organismal development. The myc gene originally came to light as a retroviral oncogene (v-myc) associated with a wide range of acute neoplasms. It was later shown to be a virally transduced cellular gene (c-myc) which is a member of family of on- genes (c-myc,N-myc,L-myc). These family members are themselves subject to a bewildering assortment of genetic rearrangements associated with many different types of tumors derived from many different types of cells. These rearrangements (including chromosomal translocation, viral integration, and gene ampli?cation) act to uncouple expression of the myc family genes from their normal physiological regulators. The chapter by LIU and LEVENS - scribes the key pathways leading to regulation of myc expression, showing that such regulation occurs at several different levels and through multiple mechanisms.
Before the introduction of antisepsis and inoculation, people commonly died due to unsanitary conditions in the home, or following surgery or childbirth. Between them, the great scientists Louis Pasteur (1822-1893) and Joseph Lister (1827-1912) extended widely the practice of inoculation and revolutionized medical practice. Pasteur's discovery that living organisms are the cause of fermentation formed the basis of the modern germ theory. Following Pasteur's researches, Lister proceeded to develop his antiseptic surgical methods. These breakthroughs in medicine are to be reckoned among the greatest discoveries of the nineteenth century.
A practical hands-on bench book covering difficult areas of autopsy for the modern pathologist. Rutty's book is unique - chapters deal with issues never previously discussed and have been specifically selected to fill a gap in the market, not just re-hash old ideas. Designed for consultants and trainees alike, not only pathologists of all types but also non-medics involved with the dead in any way - lawyers, police, bereavement officers, undertakers. The first volume has become a reference aid to autopsy issues for all grades of lawyers. Thus the audience that the book reaches is greater than a pure autopsy or forensic pathology textbook.
The era of molecular pathology has arrived. From its promising beg- nings in research laboratories, the field has grown, and continues to grow, to become a vital part of the care of an ever-increasing number of patients. Because of its recent emergence from the research taboratory, many molecuIar pathology protocols we still to be found in the primary litcramre, and have not appeared in a text. MO~PCU~Q~ Padhoiogy Protocob contains la- ratory protocoIs that have been developed by many of the authors for use in clinical molecular pathology laboratories and describe in detail Row to perform these assays. This book is therefore intended for clinical laboratory use by medical technologists and pathologists. It will dso be of interest to research workers who are performing these assays. In its broadest meaning, pathology is the study of disease, and therefore it follows that any disease for which the molecular basis is understood would be suitable as a topic for inclusion in this work. When seiecting protocols, it was necessary to place limits on the number of chapters that could be feasibly presented in a single work. Those protoculs that were selected are performed more frequently, or have achieved recognition as having important diagnostic utility in contemporary practice. A decision was made to exclude inherited genetic diseases with certain exceptions, such as those diseases that are associated with thrombotic states and are part of the traditional dumain of pathology.
One Health is an emerging concept that aims to bring together human, animal, and environmental health. Achieving harmonized approaches for disease detection and prevention is difficult because traditional boundaries of medical and veterinary practice must be crossed. In the 19th and early 20th centuries this was not the case then researchers like Louis Pasteur and Robert Koch and physicians like William Osler and Rudolph Virchow crossed the boundaries between animal and human health. More recently Calvin Schwabe revised the concept of One Medicine. This was critical for the advancement of the field of epidemiology, especially as applied to zoonotic diseases. The future of One Health is at a crossroads with a need to more clearly define its boundaries and demonstrate its benefits. Interestingly the greatest acceptance of One Health is seen in the developing world where it is having significant impacts on control of infectious diseases. "
Many new antileukotriene drugs are now marketed as antiasthma drugs and represent the first new drugs in this field since the 1970s.

In eukaryotic cells, the nuclear genome and its transcriptional apparatus is separated from the site of protein synthesis by the nuclear envelope. Thus, a constant flow of proteins and nucleic acids has to cross the nuclear envelope in both directions. This transport in and out of the nucleus is mediated by nuclear pore complexes (NPCs) and occurs in an energy and signal-dependent manner. Thus, nucleocytoplasmic translocation of macro molecules across the nuclear envelope appears to be a highly specific and regulated process. Viruses that replicate their genome in the cell nucleus are therefore forced to develop efficient ways to deal with the intracellulZlr host cell transport machinery. Historically, investigation of Polyomavirus replication allowed identification ofsequences that mediate nuclear import, which led subsequently to our detailed understanding of the cellular factors that are involved in nuclear import. Transport ofmacromolecules in the opposite direction, however, is less well understood. The investigation of retroviral gene expression in recent years pro vided the first insights into the cellular mechanisms that regulate nuclear export. In particular, the detailed dissection of the function of the human immunodeficiency virus type I (HIV-I) Rev trans-activator protein identified CRMI, as a hona fide nuclear export receptor. CRM I appears to be involved in the nucleocytoplasmic translocation of the vast majority of viral and cellular proteins that have subsequently been found to contain a Rev-type leucine-rich nuclear export signal (NES)."
This volume provides an overview of the latency strategies developed during the estimated 200 Myears long coevolution of Alpha-, Beta- and Gammaherpesvirinae and their host species. The main emphasis is on herpesviruses infecting humans. However, relevant cases if herpesviruses infecting animals are covered as well. Special emphasis is drawn on results on molecular mechanisms regulating latent promoters of herpesvirus genomes and signals and molecular pathways resulting in reactivation of latent viral genomes. To balance the volume, epigenetic mechanisms (DNA methylation, histone modification, chromatin structure) involved in cell type specific expression of growth-transformation-associated Gammaherpesvirus genes will also be discussed at length)
The OHOLO conferences are sponsored by the Israel Institute for Biological Research and take their name from the site of the ?rst meeting on the shores of Lake Kinnereth. The purpose of these meetings is, as it was at their inception over 50 years ago, "to foster interdisciplinary communication between scientists in Israel, and to provide added stimulus by the participation of invited scientists from abroad". The core of the organizers of the OHOLO conferences are scientists from the Israel Institute for Biological Research. From time to time a particular OHOLO conference cooperates with an international scienti?c organization. The present 46th OHOLO Conference marks the resumption of the OHOLO tradition after 8 years of interruption caused by events beyond our control. It is my belief that our uncomp- mising commitment to excellence in research and development in the various areas of science in Israel is essential to our survival in this troubled region. The OHOLO conference tradition is a re?ection of this conviction. The present 46th OHOLO Conference entitled: The Challenge of Highly Pathogenic Microorganisms - Mechanisms of Virulence and Novel Medical Countermeasures intends to address the unique virulence features and ho- pathogen interactions of microorganisms constituting emerging biothreat with emphasis on Y. pestis, B. anthracis, F. tularensis and Orthopox viruses. Accordingly we selected classical microbiological as well as genomic, proteomic & transcr- tomic approaches towards developments of novel prophylactic and post-exposure treatment, as well as updated strategies of diagnostics and bioforensics.
The books in this acclaimed series are the most detailed, up-to-date accounts of the field available. Volume 3 explores the oncogenic potential shared by retroviruses of different species, the widespread presence of retrovirues in nature, and the role of retroviruses in normal development and pathogenesis.
The understanding how complement relates to glomerular diseases has evolved considerably during the last years. Substantial evidence has accumulated that explain how a defective or deregulated complement system results in kidney diseases. The combination and close interaction of basic research with clinical medicine has demonstrated an important role of complement effector and regulatory proteins in pathological settings of the kidney. A large panel of distinct human kidney diseases such as hemolytic uremic syndrome (HUS), membrano proliferative glomerulonephritis (MPGN), systemic lupus erythematosus (SLE) and in ischemic reperfusions injury and transplantation are caused by defective complement control. Genetic analyses have identified mutations in complement regulators that are associated with these diseases. Mutations have been identified in the fluid phase alternative pathway regulator Factor H and the membrane regulator Membrane Cofactor Protein MCP (CD46). The functional characterization of the mutant proteins allows to define the pathophysiological events on a molecular level. These new concepts and data on disease mechanisms already allowed to establish new diagnostic and novel promising therapeutic approaches for several human kidney diseases.
Epigenetic modification of cellular genomes is a fascinating means of regulating tissue- and cell type-specific gene expression in all developmental stages of the life of an organism. Carefully orchestrated processes, such as DNA methylation and a plenitude of specific histone modifications secure the faithful transmission of gene expression patterns to progeny cells. Upon chronic infection, the epigenetic cellular balance can become disrupted and, in the long run, through the epigenetic reprogramming of host cell genomes, contribute to the malignant conversion of formerly healthy cells, in many cases preceded by the establishment of an epigenetic field of cancerization. The present volume undertakes to highlight the interactions of infectious pathogens and their effector molecules with the epigenetic regulatory machinery of the cell. Clearly, the recent take-off of epigenetics research did not leave Research on Infectious Diseases and Infection-Associated Cancer untouched. This resulted in a great many of clinically relevant data on understanding the molecular mechanisms of chronic infectious disease. Infectious pathogen- and disease-specific epigenetic alterations are already being used for the early detection of malignant disease and for the prediction of chemotherapy resistance or response to treatment.
