The discovery of the human T cell leukemia virus type I in the late 1970s heralded a new era in retrovirology. For the first time, it was demonstrated that a retrovirus could play a role in the development of a human disease, in this case adult T cell leukemia (ATL). Several years later, the acquired immunodeficiency syndrome (AIDS) epidemic began, and it was dem- strated that a retrovirus, originally designated the human T cell lymp- tropic virus type 3, was the causal agent of this syndrome. This virus, later named the human immunodeficiency virus type 1 (HIV-1), has since been extensively studied in terms of its pathogenesis as well as its ability to elicit immune responses. In that time, a tremendous amount of information has been obtained about the virus. Although recent drug regimens have been useful in significantly lowering viral loads and perhaps maintaining an asymptomatic state among individuals infected with HIV-1, an established "cure" for AIDS eludes us. In addition, the effective drug therapies are very expensive, and are not available to infected people in the third world, where greater than 90% of new infections occur. Furthermore, the development of viral resistance against the drug therapies is an additional concern. Despite extensive study, no effective vaccine has been developed. One of the problems in developing an effective vaccine against HIV-1 is the ability of the virus, particularly in the immunogenic envelop glycoprotein, to undergo amino acid hypervariability.

Scientific research on dengue has a long and rich history. The literature has been touched by famous names in medicine- Benjamin Rush, Walter Reed, and Albert Sabin, to name a very few- and has been fertile ground for medical historians . The advances made in those early investigations are all the more remarkable for the limited tools available at the time. The demonstration of a viral etiology for dengue fever, the recognition of mosquitoes as the vector for transmission to humans, and the existence of multiple viral variants (serotypes) with only partial cross-protection were all accomplished prior to the ability to culture and characterize the etiologic agent. Research on dengue in this period was typically driven by circumstances. Epidemics of dengue created public health crises, although these were relatively short-lived in any one location, as the population of susceptible individuals quickly shrank. Military considerations became as a major driving force for research. With the introduction of large numbers of non-immune individuals into endemic areas, dengue could cripple military readiness, taking more soldiers out of action than hostile fire. Dengue and dengue hemorrhagic fever, which assumed pandemic proportions during the latter half of the last century, have shown no indication of slowing their growth during this first decade of the twenty-first century. Challenges remain in understanding the basic mechanisms of viral replication and disease pathogenesis, in clinical management of patients, and in control of dengue viral transmission. Nevertheless, new tools and insights have led to major recent scientific advances. As the first candidate vaccines enter large-scale efficacy trials, there is reason to hope that we may soon "turn the corner" on this disease.

Topics covered in this volume include gene survival in emergent genomes, evolution of prokaryotic pangenomes, horizontal-transfer of host-adaptibility systems and more.

Species of aspergilli are common in man's environment and are responsible for a wide spectrum of human and animal disease, ranging in animals from mycotic abortion to aflatoxicosis and in humans from localized colonization of the ear or skin to life-threatening systemic infection of neutropenic patients. In recent times, invasive aspergillosis has become increasingly important as a cause of morbidity and death, initially in patients receiving immunosuppression prior to organ transplantation, and latterly in haematologic patients rendered neutropenic by underlying disease or chemotherapy. In some centres, the condition has been recorded in more than 40% of patients dying with acute leukaemia. Laboratory diagnostic procedures are not always helpful and the diagnosis depends largely on clinical parameters. The clinician is faced with yet another problem, that of management. At present, antifungal therapy of invasive aspergillosis can be largely ineffectual, and the mortality rate remains unacceptably high. Since Aspergillus fumigatus was first described almost 125 years ago, several other pathogenic species have been recognized. The marked biosynthetic abilities and varied mechanisms of gene recombination of aspergilli have long commanded attention in food technology and genetics. Their equally varied abilities to cause disease have attracted the interest of toxicologists, allergists and physicians concerned with infectious diseases.

This book aims to cover the applications of nanotechnology against human infectious diseases. The chapters of the book discuss the role of nanotechnology in the efficient diagnosis and treatment of these diseases. It explicitly provides an overview of nanodiagnostics for infectious diseases from nanoparticles-based, nanodevice-based, and point-of-care platforms. The book also covers the state-of-the-art review of recent progress in biomimetic and bioengineered nanotherapies to treat infectious diseases. It also presents a nano carrier-based CRISPR/Cas9 delivery system for gene editing and its applications for developing interventional approaches against communicable diseases. Further, it reviews the recent developments in nanotechnology to engineer nanoparticles with desired physicochemical properties as a line of defense against multi-drug resistance micro-organisms. Cutting across the disciplines, this book serves as a guide for researchers in biotechnology, parasitology, and nanotechnology.

In the summer of 1984, both of us were working with Professor Yechiel Becker in the Laboratory for Molecular Virology at the Hebrew University-Hadassah Medical center in Jerusalem. During a discussion about the increasing number of specialized journals and monographs, Dr. Becker pointed out that none covered both the clinical and molecular aspects of neurotropic virus infections, and he urged us to develop such a book with the help of colleagues who were conducting highly-regarded research in their individual areas related to neurotropic viruses. The responses to our request were gratifying, and each contribution provided both a comprehensive clinical description of the neurologic disease produced by a specific virus and an up-to-date review of the current research in the pathogenesis of the disease, with particular attention given to molecular mechanisms. Most, but not all chapters were written by clinical neurologists who applied basic science strategies and methodologies to the question of how neurotropic viruses produce disease. other chapters were written by virologists known for their longstanding commitment and expertise in the analysis of the pathogenesis of neurotropic virus infections. Thus, this unique monograph should be valuable to all clinicians caring for patients with CNS viral diseases and to "neurovirologists" needing an update of the clinical and molecular pathogenesis of neurotropic virus infections. While this monograph was being prepared, a rapidly expanding literature indicated that the human lenteviruses, human immunodeficiency viruses (HIV) and HTLV-1 were highly neurotropic.

This brief, accessible treatise harnesses the neurophysiological processes of learning to create an innovative and powerful approach to therapy. It sets out a non-pathologizing alternative not only to the current medicalized conception of diagnosis and treatment but also to the labeling of relatively normal reactions to stressors and upsets as illnesses. Rooted in the neurobiology of human learning, the book's approach to treatment, Neuro-Cognitive Learning Therapy, characterizes maladaptive behavior patterns as learned responses to upsetting conditions-processes which can be unlearned. In addition, the coverage includes a clinical teaching guide for bringing NCLT theory and methods into the training curriculum. This groundbreaking volume: Proposes a non-stigmatizing learning model for therapy, Neuro-Cognitive Learning Therapy. Introduces the concept of the connectome and explains its critical role in mental health and illness. Differentiates between the unconscious and automaticity in cognition and behavior. Addresses the applicability of NCLT to biologically-based mental disorders. Offers case studies illustrating NCLT in contrast with commonly-used approaches. Includes a chapter-by-chapter clinical teaching guide with therapeutic principles and discussion questions. Provides a comprehensive therapeutic framework for practitioners of all orientations. Depathologizing Psychopathology gives neuropsychologists, psychiatrists, clinical social workers, and child and school psychologists new ways of thinking about mental illness and learning about learning for a bold new step in the evolution of mind/brain knowledge.

The purpose of the book is to bring the two disciplines - vascular mechanics and pathology - together. In addition, the book bridges the gap in our knowledge and enhances engineering applications in medicine. This cutting-edge work presents the use of veins as arterial grafts and discusses the role of vein valves in graft stenosis. The book illustrates aneurysm formation, growth, and rupture, using pressure vessel principles. This new work details the investigation of, amongst other topics, aortic dissection, showing for the first time that the aortic root mechanics plays a vital role in the development of this pathology.

This new edition describes the role of heat shock proteins in the life cycle of malaria parasites, particularly in the context of intracellular parasite stages. Thoroughly revised, this work provides a general introduction to the structural and functional features of heat shock proteins with a special focus on their role as molecular chaperones in ensuring protein quality control. The emphasis is on the heat shock protein families from Plasmodium falciparum, and their role in proteostasis and the development of malaria pathology. Moreover, the authors explore the latest prospects of targeting heat shock proteins in antimalarial drug discovery either directly or in combination therapies. Readers will experience a functional analysis of the individual families of heat shock proteins and their cooperation in functional networks, including both the parasite-resident proteome and the exportome released into host cells during intracellular stages. Subcellular and extracellular organelles such as the apicoplast and the Maurer's Clefts associated with Plasmodium species are discussed in detail. The book highlights the role of heat shock proteins in the development and function of these structures. Biochemical expertise and the inclusion of novel therapeutic solutions make this collection a unique reference for experts in heat shock protein research, parasitology and infectious diseases, cell stress, molecular biology and drug discovery. Not least, advances in malaria control will contribute to ending epidemics and ensuring healthy lives in line with the UN Sustainable Development Goals.

Sudden cardiac death represents a highly heterogeneous group of cardiovascular disorders. While some may initially think of sudden death as primarily an arrhythmogenic event, this actually represents the minority of cases of sudden cardiac death. In the vast majority of cases, there is an underlying anatomic disorder of the cardiovascular system responsible for the ultimate hemodynamic collapse known as sudden cardiac death. This book will provide an atlas type review of ischemic and non-ischemic etiologies of sudden cardiac death. Beyond the atlas, however, will be a "clinical pathologic correlation" for each described disorder providing practicing clinicians with practical information to facilitate proper diagnosis and treatment. While an increasing array of noninvasive diagnostic tools continue to develop, the sad fact remains that many of the physicians and operators of these new diagnostic modalities have never actually seen specimens which demonstrate the fundamental pathologic abnormalities. This ability to see first hand the underlying pathology creates an opportunity to advance the science and enhance ones understanding of these disease processes. There is not a comprehensive text on this subject on the market today which provides clinical and patholigical material in such a comprehensive manner.

Public Health Microbiology: Methods and Protocols is focused on microorganisms that can present a hazard to human health in the course of everyday life. There are chapters dealing with organisms that are directly pathogenic to humans, including bacteria, viruses, and fungi; on organisms that produce toxins during growth in their natural habitats; on the use of bacteriocins produced by such organisms as lactobacilli and bifidobacteria; as well as several chapters on hazard analysis, the use of disinfectants, microbiological analysis of cosmetics, and microbiological tests for sanitation equipment in food factories. Additional chapters look at the use of animals (mice) in the study of the various characteristics of milk and their relationships with lactic acid bacteria in particular. Other chapters focus on special methods for determining particular components of milk. In particular, in Parts I and II, on bacterial and viral pathogens, special attention is given to methods for PCR detection of genes with resistance to tetracycline, as well as to Salmonella enterica; for identification and typing of Campylobacter coli; for detection of the abundance of enteric viruses, hepatitis A virus, and rotaviruses in sewage, and of bacteriophages infecting the O157: H7 strain of Escherichia coli. Part III offers methods for computerized analysis and typing of fungal isolates, for isolation and enumeration of fungi in foods, and for the determination of aflatoxin and zearalenone

The novel coronavirus 2019 (COVID-19) has caused a serious global pandemic in just one year. Nearly every country and territory in the world has been affected by the virus. The virulence and infection rate of the virus are profound, and has required extreme social distancing measures across the globe in order to prevent overwhelming the healthcare services and hospitals. COVID-19 appears to have the greatest effects on elderly individuals and those who have co-morbid diseases, such as diabetes and obesity. As the cases and death rate remain high, there are justified fears of this virus remaining for several months or years to come. To address this, a rapid and unprecedented worldwide mobilization effort has begun to identify effective treatments and develop vaccines. As these begin to be deployed and administered across the globe, many now feel the virus will be brought under control and lives will eventually return to normal. This new volume will increase readers' understanding of the ongoing COVID-19 pandemic through a series of chapters that address these concerns. Leading experts will discuss new treatment approaches, vaccine development, mental health aspects of the pandemic, and convey the results of survey studies. The book will be an excellent resource for researchers studying virology, metabolic diseases, respiratory disorders, and clinical scientists, physicians, drug companies, and healthcare services and workers.

This book provides a comprehensive treatise on the chemical and biochemical consequences of damaging free radical reactions, the implications for the pathogenesis of disease and how this might be controlled endogenously and by radical scavenging drugs. Oxidative stress may be influenced by exogenous agents of oxidative stress, radiation, trauma, drug activation, oxygen excess, or by exogenous oxidative stress which is associated with many pathological states including chronic inflammatory disorders, cardiovascular disease, injury to the central nervous system, and connective tissue damage. This and many other such aspects are presented clearly and in depth.

The development of antioxidant drugs depends on the understanding of the mechanisms underlying the generation of excessive free radicals "in vivo," the factors controlling their release and the site of their action. This excellent volume presents an up-to-date account of the current state of knowledge in these areas.

This book comprehensively reviews various vector-borne diseases and their control methods. It discusses morphology, life history, and pathogenicity of protozoan and helminth parasites. Further, it analyzes host-parasite interactions and their adaptation within the host system for understanding parasitic infections. The book discusses the complex life cycle, biochemical adaptations, and molecular biology of the parasites. It investigates the immunological response to different infectious agents and explores new targets for combined therapeutic approaches. It also summarizes the evolution of parasitism and the ecology of parasites of the different phylum. Lastly, it provides information on vector biology emphasizing the role of basic vector research in developing future disease control methods and improving upon the existing approaches.

This volume covers the most important parasitic protists that are known to infect humans. The pathogens discussed cause diseases like toxoplasmosis, malaria, cryptosporidiosis, leishmaniasis, amoebiasis, trichomoniasis, and giardiasis. Readers from microbiology will appreciate the special focus on protist cell biology. As demonstrated in several of the chapters, these parasites are characterized by peculiar structures and organelles that cannot be found in mammalian cells - even though both are eukaryotic. The book employs light and electron microscopy to display the changing morphology in various stages of parasitic development. In turn, the results are supplemented by transcriptome and proteome profiles that help to describe how these changes take place on a molecular level. Both researchers and clinicians from tropical medicine will find essential and practically applicable background information on these increasingly important pathogens.

This Springer Protocols manual is a practical guide to the application of key molecular biology techniques in microbiological research.

Rabies is one of the oldest known pathogens, is incurable, and has the highest fatality rate of all infectious diseases. The Americas is the only region with bat rabies virus, including vampire bat rabies. The region is rich in cultural references and notable for many discoveries in the field, including the current vaccine potency test, diagnostic assay, conception of oral vaccines for wildlife, the first human survivor and the first successful canine rabies program executed at a broad level. Rabies remains the most important viral zoonosis, with tens of thousands of human fatalities and tens of millions of exposures annually, which can be used to model for other pathogens, such as COVID-19. There is an international effort to eliminate human rabies caused by dogs over the next decade, and the Americas represent the primary region with the greatest proof-of-concept evidence to accomplish this goal.  This two-volume set addresses the medical history and modern results of rabies in countries throughout the Americas, including the implications of and on cultural, economic, sociological, and research developments in the region. Volume I presents an overview of concepts critical to the study of rabies in the region, including evolutionary aspects, reservoir ecology and control, elimination efforts, vaccine development, and disease hallmarks and progression. It also analyzes the long-term cultural, social, and economic impacts of the disease in the Americas.
