Leishmania is a vector-borne pathogenic parasite found in 88 countries worldwide and is the causative agent of leishmaniasis. The different Leishmania species infect macrophages and dendritic cells of the host immune system, causing symptoms that range from disfiguring cutaneous and mucocutaneous lesions, widespread destruction of mucous membranes, or visceral disease affecting the haemopoetic organs. The recent publication of the complete genome sequences of three different Leishmania species provides new insights into this leading pathogen and presents scientists with an exciting resource to improve the understanding of its complex molecular and cellular biology. In this book, internationally recognized Leishmania experts critically review the most important aspects of current Leishmania research, providing the first coherent picture of the organism's molecular and cellular biology since the publication of the genome sequence. Chapters are written from a molecular and genomic perspective and discuss in depth Leishmania-specific aspects of trypanosomatid biology and pathology. Topics include: diagnosis and epidemiology, genome structure and content, regulation of gene expression, the Leishmania proteome, the Leishmania metabolome, Leishmania differentiation, interaction with the sand fly vector, drug discovery, drug resistance, and much more. This will be essential reading for all researchers working with Leishmania, trypanosomes, and protozoa; and is recommended for all biology and medical libraries.

The last decade has seen an explosive increase in the volume of research on and knowledge of lactic acid bacteria, organisms of prime importance for the production of dairy products and the fermentation of various vegetables. This issue of Antonie van Leeuwenhoek, written by international experts in the field, documents these recent exciting developments with respect to genetics, metabolism and application of lactic acid bacteria for industrial and potential medical applications. This book is essential for all researchers with an interest in the fundamental biology of Gram-positive bacteria, in particular in lactic acid bacteria and their applications, not only as a source of reference but also as an indispensable source of information for further development and exploration of this field.

Adhesion plays a major role in the bacterial lifestyle. Bacteria can adhere to organic and inorganic surfaces, to each other, and of course to host cells during pathogenesis. The focus of this book is: how are such adhesion phenomena best studied? Microbial genetics experiments have greatly enhanced our knowledge of what bacterial factors are involved in adhesion. For numerous reasons, though, biochemical and structural biology knowledge of the molecular interactions involved in adhesion are limited. One major problem has been a lack of interdisciplinary research and understanding in the field. On the one hand, the microbiologists lack detailed knowledge of the biophysical possibilities and have limited access to the frequently expensive instrumentation involved while on the other hand, the experts in these methods frequently do not have access to the biological materials, nor do they necessarily understand the biological questions to be answered. The purpose of this book is thus to overcome this gap in communication between researchers in biology, chemistry and physics and to display the many ways and means to investigate bacterial adhesion. We hope to stimulate new and ground-breaking research.

The World Health Organization has identified chronic alcohol consumption as one of the top ten risk factors for worldwide burden of disease. The International Agency for Research on Cancer has identified alcohol as carcinogenic to humans, including cancers of the upper aerodigestive tract, colon, liver and breast. Alcohol's actions may be direct e.g. effects on retinoic acid and one-carbon metabolism, or indirect, through metabolites such as acetaldehyde and reactive oxygen species or through various signaling pathways that influence cell cycle and apoptosis that may contribute to carcinogenesis. This report reviews the state of the art in alcohol-related cancer research in ten chapters.

"HPV and Cancer" is a concise read that covers all aspects of the Human Papilloma Virus as it relates to human cancers. While written by professionals, it design to be understandable by those that are not in the field, yet it has the technical details that professionals want to stay abreast of this changing field. The book starts out the history of HPV and progresses into the molecular biology of the virus and our current understand of the structure and functions of the proteins and genes it encodes. We then look at the dynamic trends of this infectious agent in the human population, how it interacts with human cells, and the role it plays with other organisms to produce both benign and malignant tumors. Lastly, there is a discussion about a new vaccine for HPV and the hopes that are held by many to change the trends with this virus and the associated cancers it produces.

Biosynthesis of cellular and viral DNA and RNA has been a major topic in molecular biology and biochemistry. The studies by Arthur Kornberg and his colleagues on the in-vitro synthesis of DNA have opened new avenues to understanding the processes controlling the duplication of the genetic information encoded in the DNA and RNA of bacterial and mammalian cells. Viral nucleic acids are replicated in infected cells (bacterial, plant, and animal) by virus coded enzymes with or without the involvement of proteins and enzymes coded by the host cells. The ability of the virus to replicate its genome within a relatively short period in the infected cell makes it an excellent biological tool for studying the molecular events in nucleic acid replication. Indeed, the identification of a number of virus-coded proteins that participate in the biosynthesis of X174 and SV40 DNA has led to the construction of in-vitro systems for the study of nucleic acid biosynthesis. Similarly, studies on the replication of other phage, animal and plant viruses have provided an insight into the nucleic acid sequences from which DNA synthesis is initiated, as well as the proteins and enzymes that regulate the catalyse biosynthetic processes. Investi gation of the molecular processes involved in the replication of cellular and mitochondrial genomes has gained momentum from the rapid developments in the analyses of viral nucleic acid biosynthesis."

It has been known for over 150 years that hallmarks of inflammation can be observed in the wall of atherosclerotic vessels. It was, however, not clear if this inflammation is the cause or the consequence of atherogenesis. More recently, it has become evident that inflammation mediated both by innate and adaptive immunity is instrumental even in the earliest stages of the development of atherosclerotic lesions, i.e., that it plays an important pathogenetic role. In this volume, international experts in the field discuss the pathogenetic, diagnostic, preventive and possible therapeutic relevance of inflammation in atherogenesis. This book is intended for researchers and physicians in the fields of vascular biology, immunology and atherosclerosis.

"Nuclear envelope (NE) defects have been linked to cancer biology since the mid-1800s, but it was not until the last few years that we have begun to understand these historical links and to realize that there are myriad ways that the NE impacts on tumorigenesis. The NE is a complex double membrane system that encloses the genome while providing structural support through the intermediate filament lamin polymer and regulating protein/ mRNA trafficking and signaling between the nucleus and cytoplasm via the nuclear pore complexes (NPCs). These functions already provide some mechanisms for NE influences on cancer biology but work in the past few years has elucidated many others. Lamins and many recently identified NE transmembrane proteins (NETs) have been now shown to function in DNA repair, regulation of cell cycle and signaling, apoptosis, cell migration in metastasis and nuclear architecture and morphology. This volume presents a comprehensive overview of the wide range of functions recently identified for NE proteins and their relevance in cancer biology, providing molecular mechanisms and evidence of their value as prognostic and diagnostic markers and suggesting new avenues for the treatment of cancer. Indeed some of these recent links are already yielding promising therapies, such as the current clinical trial of selective inhibitors of the nuclear export factor exportin in certain types of leukemia, melanoma and kidney cancer."

Volume 12 in this series explores the latest experimental and clinical uses of stem cells in the treatment of disease and of injuries and reviews methods for isolating multipotent endothelial-like cells from human adipose tissue and discusses clinical applications in cell therapy and regenerative medicine.

The book is organized in five parts: Cancer Stem Cells, Pluripotent Stem Cells, Dendritic Stem Cells, Regenerative Medicine and General Applications. The first section includes chapters on histamine in the neural and cancer stem cell niches and emerging concepts of stem cell organization in the normal lung and in lung cancer. The section on Pluripotent Stem Cells includes discussion of the differentiation of dendritic cells from human induced pluripotent stem cell and the molecular mechanisms involved in reprogramming human somatic cells to generate induced pluripotent stem cells. Additional chapters cover the differentiation of induced pluripotent stem cells into functional cardiomyocytes, characteristics of satellite cells and multipotent adult stem cells in the skeletal muscle. The section on Dendritic Stem Cells explores the critical role of notch signaling in the differentiation and function of dendrite. Other chapters cover hypertensive emergencies in children after stem cell transplantation and overcoming the radio resistance of lung cancer stem cells. The section on Regenerative Medicine reports on experiments on improved renal revascularization in pigs using stem cells and phenotypic correction of murine Hemophilia A using cell-based therapy. The concluding section, General Applications, discusses such topics as methods in mathematical modeling for stem cells, as well as molecular and functional characterization of human adipocytes.

Like its eleven predecessors in the series," " this volume stands out for its comprehensive approach, its roster of some 51 expert contributors representing a dozen different countries and its up-to-date review of leading-edge technology and methods.

Because of the increasing burden of hepatitis C and fatty liver disease, there is an explosion in the prevalence of chronic liver failure and hence its complications. The onset of Hepatic Encephalopathy (HE) in these patients has a significant impact on the quality of life, morbidity and mortality. Unfortunately, the approach observed by most clinicians to this complex disorder is minimalistic. Hepatic Encephalopathy provides a comprehensive review on pathophysiology and clinically important aspects in HE. Topics in basic physiology, nitrogen metabolism, new insights into pathogenesis and brain edema are covered in great detail. The authors have made a special effort by simplifying the complex aspects of pathogenesis and diagnosis so that it can be easily understood and applied clinically. This volume also focuses on recent developments regarding diagnoses of subtle forms of HE, also known as minimal or covert HE as well as on new treatments. Hepatic Encephalopathy will be of great value to gastroenterologists, hepatologists, pathologists, medical residents, fellows, internists, and general practitioners who treat patients with hepatic encephalopathy.

This book provides a survey of recent advances in the development of antibiofilm agents for clinical and environmental applications. The fact that microbes exist in structured communities called biofilms has slowly become accepted within the medical community. We now know that over 80% of all infectious diseases are biofilm-related; however, significant challenges still lie in our ability to diagnose and treat these extremely recalcitrant infections.

Written by experts from around the globe, this book offers a valuable resource for medical professionals seeking to treat biofilm-related disease, academic and industry researchers interested in drug discovery and instructors who teach courses on microbial pathogenesis and medical microbiology.

This latest addition to the Methods in Molecular Medicine series, Anti- ral Methods and Protocols, is opportune because there is an increasing int- est in discovering compounds that are effective against both chronic and acute viral infections. A number of the methods described in the volume are unp- lished and their inclusion indicates the speed at which this field is moving. This volume is not a review but each chapter contains methods validated by the experts who have spent time in developing the protocols. The hallmark of this series is the comprehensive way in which the me- ods are described, which includes a list of all the reagents needed for each protocol. Of importance is the section on tips and pitfalls that the authors have discovered while developing their protocols. The manual itself is designed to be used by researchers in universities and industry who are familiar with a range of biological techniques but who want to set up quickly a novel assay system. We encourage a dialog between readers and authors, which may also result in useful collaborations.

The development of recombinant DNA technology has made a marked impact on molecular virology. The cleavage of viral DNA genomes with restriction enzymes and the cloning of such DNA fragments in bacterial p1asmids has led to the amplification of selected viral DNA fragments for sequencing and gene expression. RNA virus genomes which can be transcribed to their cDNA form were also cloned in bacterial p1asmids, facilitating the study of RNA virus genes. With the elucidation in recent years of the promoter sequence of various viral genes and the expression of these genes in bacteria or yeast, the understanding of many viral gene functions has made great progress. Cloning and expression of viral genes in mammalian cells was made possible by the construction of shuttle plasmid vectors which carry the origins of DNA replication from bacteria and/or mammalian viruses. The expression of viral genes in bacteria, yeast and eukaryotic cells gives reason to hope that it will be possible to produce viral antigens in large quantities for use as human or animal vaccines. The present volume attempts to capture for the reader some of the high lights of recombinant DNA research in the field of animal and plant viruses."

Explains the new methodologies by which viral diseases can be definitively diagnosed in a few hours, especially molecular methods. The many new methods now being developed are based largely on the application of the polymerase chain reaction to the detection of viral genomic material. Accessible to

This book gathers contributions by 16 international authors on the phenomenon "bats," shedding some light on their morphology, the feeding behaviors (insects, fruits, blood) of different groups, their potential and confirmed transmissions of agents of diseases, their endo- and ectoparasites, as well as countless myths surrounding their lifestyle (e.g. vampirism, chupacabras, batman etc.). Bats have been known in different cultures for several thousand centuries, however their nocturnal activities have made them mysterious and led to many legends and myths, while proven facts remained scarce. Even today, our knowledge of bats remains limited compared to other groups in the animal kingdom. Also, their famous ability to avoid collisions with obstacles during their nightly flights with the help of a sophisticated and unique system using ultrasound waves (which are transmitted and received) is as poorly studied as birds finding their way from continent to continent. In recent times, where globalization transports millions of people and goods from one end of the earth to the other, there are increased risks posed by agents of diseases, as a result of which bats have received increasing attention as potential vectors. These suppositions are based on their proven transmission of viruses such as rabies. In dedicated chapters, the book addresses the following topics: * The world of bats * The astonishing morphology of bats * Bats as potential reservoir hosts for vector-borne diseases * Bat endoparasites * Macroparasites - ectoparasites * Glimpses into how bats fly * Blood-licking bats * Vampirism in medicine and culture * Chupacabras and "goat milkers" * Myths on candiru As such, this book provides a broad range of information for all non-experts interested in biological topics, but also for people working in this field, as well as physicians and veterinarians who are confronted with clinical cases, and for teachers and students interested in expanding their knowledge of biology and of past and present cultures.

Natural Products in Vector-Borne Disease Management explores the potential application of natural products in vector control and disease management. The chapters discuss the global impact of specific vector-borne diseases, gaps in management, and natural products in specific stages of development - discovery, optimization, validation, and preclinical/clinical development. Toxic effects and mechanisms of action are also discussed. This book also explores how therapeutic plant derivatives can be used to combat the vectors of infection and how natural products can be used to manage and treat vector-borne diseases like malaria, leishmaniasis, dengue, and trypanosomiasis. With the inclusion of case studies on field and clinical applications and the contributions from experts in the field, Natural Products in Vector-Borne Disease Management is an essential resource to researchers, academics, and clinicians in parasitology, virology, microbiology, biotechnology, pharmacology, and pharmacognosy working in the field of vector-borne diseases.

In this second volume in the series The Retroviridae, the readers are treated to up-to-date reviews on these viruses, which are found in a variety of animal species. The volume begins with important observations on the general fea tures of retrovirus entry into cells as determined by the viral envelope glyco proteins and the cell surface receptors (Chapter 1). Aspects of this virus-cell interaction form the basis for the variety of biologic effects associated with this virus family. A timely review of the oncogenic feline viruses is included next (Chapter 2). These viruses, along with the avian and murine retroviruses (Volume 1, Chapters 6 and 7), have provided valuable insight into cancer induction in other animal species, including humans. Two other major groups of retroviruses, the lentiviruses and the spuma viruses, are introduced in the present volume. Initially these groups, along with oncoviruses, were the three subfamilies in the Retroviridae. This com plex virus family has now been reclassified into seven separate genera (Vol ume 1, Chapter 2). Equine infectious anemia virus is the prototype for a lentivirus (Chapter 5). One of the first viruses discovered in nature (1904), it was only relatively recently recognized as a retrovirus. Lentiviruses are asso ciated primarily with immunologic disorders such as autoimmunity and AIDS (Chapters 3-5), but their association with neurologic disease is also well established (Chapters 4 and 5, and future volumes)."

Infectious diseases caused by bacteria remain a leading cause of death worldwide. Many of the antibiotics developed to combat bacterial infections have been rendered almost impotent due to the rapid evolution and spread of antibiotic resistance. A common and major resistance mechanism, the efflux system, enables bacteria to extrude structurally divers antimicrobials, facilitating survival in toxic environments. This book reviews the most important current research and summarizes the most spectacular discoveries in the field.

Whereas plant and insect infections are commonly caused by fungi, only a small minority of the vast diversity of fungal species is pathogenic to humans. Despite this, fungal infections cause considerable morbidity and mortality worldwide. This volume is dedicated to the biology, clinical presentation and management of invasive fungal infections. Major pathogenic fungi are introduced by world-leading experts and the basic principles of fungal virulence are reviewed in the light of new results and experimental technologies that offer unprecedented insights into invasive infections caused by "Aspergillus," "Candida," "Cryptococcus," "Pneumocystis" and "Mucorales." In parallel, the clinical presentation of invasive fungal infections and current approaches to their diagnosis and treatment are summarized to provide an overview of human pathogenic fungi, linking pathogen biology to the clinical presentation of disease.

The development of biotechnology over the last 20 years, and particularly the use of recombinant DNA techniques, has rapidly expanded the opportu- ties for human benefits from living resources. Efforts to reduce pollution, p- vent environmental damage, combat microbial infection, improve food production, and so on can each involve fermentation or the environmental - lease of microorganisms. Many products of fermentation technology, such as alcoholic beverages, bread, antibiotics, amino acids, vitamins, enzymes, and others, have been influenced by the progress of recombinant DNA techniques. The development of new products or the more efficient manufacturing of those already being produced often involve the use of microorganisms as cell fac- ries for many productions and biotransformations. Microbial Processes and Products is intended to provide practical expe- mental laboratory procedures for a wide range of processes and products me- ated by microorganisms. Although not an exhaustive treatise, it provides a detailed "step-by-step" description of the most recent developments in such applied biotechnological processes. The detailed protocols we provide are cross-referenced in the Notes section, contain critical details, lists of problems and their troubleshooting, as well as safety recommendations that may not n- mally appear in journal articles and can be particularly useful for those un- miliar with specific techniques.
