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.

Vaccines against antigenically stable pathogens, or pathogens that only exist in a limited number of serotypes, have been very successful in the past and have drastically decreased the incidence and lethality of many diseases. However, when it comes to highly variable pathogens or viruses that exist in multiple serotypes, the traditional methods for vaccine development have reached their limits. This volume highlights the development of vaccines against such challenging pathogens. Novel approaches for immunogen design, including structure-guided vaccine development and vaccines targeting glycans, as well as adjuvants and animal models used for testing possible vaccine candidates are outlined and discussed in detail. Given its scope, the book will appeal to scientists in the fields of infectious diseases, microbiology and medicine.

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.

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 book presents a comprehensive view on mycotoxins of agricultural as well as non-agricultural environments and their health effects in humans and animals. Mycotoxins have immunosuppressive effects; but some of them can cause cancers, mutagenicity, neurotoxicity, liver and kidney damage, birth defects, DNA damage and respiratory disorders. The problem of mycotoxins is long-lasting and their direct or indirect exposures to humans and animals must be further discussed. The first chapter will cover the historical perspective of mycotoxins along with timeline while the second one will provide overview including classification of mycotoxins and mycotoxicoses. The comprehensive information/ literature on traditional, emerging and mushroom mycotoxins will be given in chapters 3, 4 and 5 respectively. Chapter 6 will deal with mycotoxins co-occurrence poisoning whereas new and masked mycotoxins will be described in chapter 7. The important aspects of mycotoxin studies like extraction, characterization and analysis and management strategies will be summarized in 8 and 9 chapters. The last chapter of the book will cover the recent developments in toxicokinetic studies of mycotoxins. The book will have the most up-to-date information and recent discoveries to deliver accurate data and to illustrate essential points to a wide range of readers including mycologists, clinicians, agricultural scientists, chemists, veterinarians, environmentalists and food scientists.

In an age of antibiotic resistant infections, the study of biofilms is increasingly important. Microbes more than often exist in complex multi-species or polymicrobial communities, making infections difficult to detect, diagnose and treat. Given the increased focus on studying biofilms in research and laboratory settings, particularly under conditions that closely mimic the clinical state, it is important to get an overview of the recent methods, model systems and tools being developed and employed in this context. This book offers readers the opportunity to learn more about current methods being used in the investigation of multi-species biofilms, both in vivo and in vitro. For this, the book highlights new technologies built and designed for the study of multiple species within biofilm communities, including those that can be leveraged for the evaluation of antimicrobial treatment approaches. The application of these state-of-the-art techniques to further our understanding of multi-species biofilms will be discussed and the reader will learn how the clinical microenvironment and the development of biofilm communities are considered when developing such tools. With cutting-edge contributions from experts in the respective domains, this book will benefit translational and basic research scientists, as well as clinicians, and is an informative resource for educators and their students.

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.

The shift of weather patterns has affected the incidence and prevalence of infectious diseases, including mycoses. Mycoses have remained neglected due to a lack of training and recognition within the medical community. Nonetheless, these diseases remain common worldwide while frequently being underdiagnosed. Climate change affects the distribution of fungal communities, provoking outbreaks in locations where these mycoses were absent or in low frequencies. Moreover, the reports of clinical cases related to new fungal pathogens have increased due to the description of new fungal species or due to the ability of some species to shift to new hosts. Thus, this book, The Impact of Climate Change on Fungal Diseases, is a contribution to the knowledge of a global environmental phenomenon and its relation to these diseases, and it serves as a guide for health professionals to dive deep into the repercussions of climate change and how they can implement measures for the prevention and control of fungal infections.

This volume focuses on the roles of long non-coding RNAs (lncRNAs) in contexts ranging from human cancers to cardiovascular disease and ageing. The role of lncRNAs in X-inactivation and those lncRNAs derived from pseudogenes, past retroelements integrated within the human genome, as well as the role these pseudogene-derived lncRNAs play in cancer development are discussed in detail. Further, the book examines the function of lncRNAs in diseases such as diabetes, in smooth muscle formation, and in the modulation of nuclear receptors, as well as in connection with perspectives on the development of personalized therapeutics. It offers an appealing and insightful resource for scientists and clinicians alike.

The Epstein-Barr virus (EBV), isolated in 1966, continues to draw worldwide attention as an important human pathogen. Its impor tance is largely related to the continuing accumulation of evidence that implicates EBV as an etiological factor for certain types of human cancer. More recent investigations on this virus have focused on the identity of the viral genes responsible for the different disease mani festations observed following viral infection. It is hoped that by thorough investigation of this virus, clues to how cancer develops from a normal cell will surface. In addition, many of the gene products are now being exploited for the development of new and more sensitive tests for the diagnosis and clinical management of individu als with EBV -associated diseases. Thus, studies on this virus continue to provide new information of importance to our understanding of the malignant process. In an effort to attract both basic and clinical scientists to the same meeting for purposes of scientific exchange and fostering a closer interaction between these individuals, a series of international symposia was initiated in 1984. The first meeting was held in Loutraki, Greece, and was attended by approximately 100 participants. The second international symposium was held in St. Petersburg, Florida, in 1986, and was attended by approximately twice as many partici pants as attended the Loutraki meeting."

Hepatitis C is a liver disease caused by the hepatitis C virus (HCV) and infects approximately 75 million individuals worldwide. It is also one of the major causes of liver cancer and liver transplants. The elucidation of the HCV genome, and the development of a whole cell system to study the virus spurred the search for novel direct acting antiviral drugs to cure this disease. This global effort culminated in the development of direct acting antiviral drugs that led to cure rates approaching 100% in all patient populations after only 8-12 weeks of therapy. These efforts resulted in one of the greatest achievements in public health and provides the potential for eliminating HCV as a major disease worldwide. This volume is aimed at a broad audience of academic and industrial scientists interested in the discovery and development of drugs to treat viral diseases and those interested in reading about one of the most unique accomplishments in biomedical research. The volume will provide a one of a kind reference work that highlights the many efforts, from the discovery of the HCV virus, to the invention of breakthrough medicines and their use in the real world to cure patients. It is the companion book to the volume "HCV: The Journey from Discovery to a Cure - Volume I".

The book is an update on contentious or unsettled issues concerning invasive diagnostic and therapeutic challenges in cancer and related disorders, focusing on the surgical approach. Topics include recommendations for the best practice in using the surgery safety checklist, surgical strategies in a variety of thoracic cancers, renal cell carcinoma, tumors of parathyroid glands, mesothelioma, and bariatric surgeries. The focus is on the diagnostic and therapeutic challenges of aggressive cancerous entities, choosing the most beneficial modes for optimal outcomes and patient survival. Chapters also address radioimaging and therapy outcomes in different intracranial lesions leading to severe neurological disabilities. The areas of medical practice addressed are still veiled in uncertainty, yet-unresolved pathogenetic background, and have a substantial component of empirical rather than evidence-based clinical approach. Pursuing and sharing new ideas and innovations is essential for improving the management and outcome. The book endeavors to disseminate and deliberate on the latest medical knowledge, studies, and advancements in surgical and diagnostic dealing with cancer. The book is addressed to physicians and surgeons, and all allied health care professionals engaged in patient care and therapy.

The book is essential for microbiologists studying the human eye, ophthalmologists treating eye infection and trauma. It also caters to students of medical microbiology and medicine.

Microbial physiology, biochemistry and genetics allowed the formulation of concepts that turned out to be important in the study of higher organisms. In the first section, the principles of bacterial growth are given, as well as the description of the different layers that enclose the bacterial cytoplasm, and their role in obtaining nutrients from the outside media through different permeability mechanism described in detail. A chapter is devoted to allostery and is indispensable for the comprehension of many regulatory mechanisms described throughout the book. Another section analyses the mechanisms by which cells obtain the energy necessary for their growth, glycolysis, the pentose phosphate pathway, the tricarboxylic and the anaplerotic cycles. Two chapters are devoted to classes of microorganisms rarely dealt with in textbooks, namely the Archaea, mainly the methanogenic bacteria, and the methylotrophs. Eight chapters describe the principles of the regulations at the transcriptional level, with the necessary knowledge of the machineries of transcription and translation. The next fifteen chapters deal with the biosynthesis of the cell building blocks, amino acids, purine and pyrimidine nucleotides and deoxynucleotides, water-soluble vitamins and coenzymes, isoprene and tetrapyrrole derivatives and vitamin B12. The two last chapters are devoted to the study of protein-DNA interactions and to the evolution of biosynthetic pathways. The considerable advances made in the last thirty years in the field by the introduction of gene cloning and sequencing and by the exponential development of physical methods such as X-ray crystallography or nuclear magnetic resonance have helped presenting metabolism under a multidisciplinary attractive angle.

When Peter Piot was in medical school, a professor warned, "There's no future in infectious diseases. They've all been solved." Fortunately, Piot ignored him, and the result has been an exceptional, adventure-filled career. In the 1970s, as a young man, Piot was sent to Central Africa as part of a team tasked with identifying a grisly new virus. Crossing into the quarantine zone on the most dangerous missions, he studied local customs to determine how this disease-the Ebola virus-was spreading. Later, Piot found himself in the field again when another mysterious epidemic broke out: AIDS. He traveled throughout Africa, leading the first international AIDS initiatives there. Then, as founder and director of UNAIDS, he negotiated policies with leaders from Fidel Castro to Thabo Mbeki and helped turn the tide of the epidemic. Candid and engrossing, No Time to Lose captures the urgency and excitement of being on the front lines in the fight against today's deadliest diseases.
