For decades it has been known that structured conformations are important for the proper functioning of most cellular proteins. However, appreciation that protein folding to the functional conformations as well as the structural maintenance of protein molecules are very complex processes has only emerged during the last ten years. The intimate interplay uncovered by this scientific development led us to realize that perturbations of the protein folding process and disturbances of conformational maintenance are major disease mechanisms. This development has given rise to the concept of conformational diseases and the broader signature of protein folding diseases, comprising diseases in which mutations or environmental stresses may result in a partial misfolding that leads then to alternative conformations capable of disturbing cellular processes. This may happen by self-association (aggregation), as in prion and Alzheimer s diseases, or by incorporation of alternatively folded subunits into structural entities, as in collagen diseases. Another possibility is that folding to the native structure is impaired or abolished, resulting in decreased stea- state levels of the correctly folded protein, as is observed in cystic fibrosis and 1-antitrypsin deficiency, as well as in many enzyme deficiencies. In addition, deficiencies of proteins that are engaged in assisting and supervising protein folding (protein quality control) may impair the folding of many other proteins, resulting in pathological phenotypes. Examples of this are the spastic paraplegia attributable to mutations in mitochondrial protease/chaperone complexes."

Leading researchers and clinicians join forces to explain how malignant melanoma develops from its benign precursor cell type. The authors focus on the molecular mechanisms involved in melanogenesis, in the malignant transformation of melanocytes, and in the further progression of primary melanomas into invasive and metastatic melanomas. They also review recent advances in our understanding of the basic biology of melanocytes and the development, migration, and differentiation of melanoblasts into melanocytes. The book provides an up-to-date understanding of the progressive mechanisms of oncological development in malignant melanoma, a likely model of malignant progress for other types of cancer, and the ongoing development of novel therapeutics.

Mammalian Toll-like receptors (TLRs) were first identified in 1997 based on their homology with Drosophila Toll, which mediates innate immunity in the fly. In recent years, the number of studies describing TLR expression and function in the nervous system has been increasing steadily and expanding beyond their traditional roles in infectious diseases to neurodegenerative disorders and injury. Interest in the field serves as the impetus for this volume in the Current Topics in Microbiology and Immunology series entitled "Toll-like receptors: Roles in Infection and Neuropathology." The first five chapters highlight more traditional roles for TLRs in infectious diseases of the CNS. The second half of the volume discusses recently emerging roles for TLRs in non-infectious neurodegenerative diseases and the challenges faced in these models with identifying endogenous ligands. Several conceptual theories are introduced in various chapters that deal with the dual nature of TLR engagement and whether these signals favor neuroprotective versus neurodegenerative outcomes. This volume should be informative for both experts as well as newcomers to the field of TLRs in the nervous system based on its coverage of basic TLR biology as well as specialization to discuss specific diseases of the nervous system where TLR function has been implicated. A must read for researchers interested in the dual role of these receptors in neuroinfection and neurodegeneration.

I assume that you already know a good deal of microbiology. In this book, I frequently use the word "we" by which I mean "you and I." Together we are going to consider bacteriology from a broader perspective and we will think our way through the important biological problems that are frequently just skipped over in every microbiology course. My most important reason for writing this book is to make accessible the relevant thinking from fields of science other than microbiology that are important to microbiology. The book is written for people that have already have a fascination with bacteria, but can see that their background for understanding is far complete. This book consists of topics that are largely omitted from microbiology textbooks and includes some mathematics, physics, chemistry, and evolutionary biology. It contains a good deal of my own work, both experimental and theoretical, together with a lot of speculation. If ten times bigger, it would be a full text book on microbial physiology. A third of the microbial physiology is covered by the recent is no longer treated even in textbook by White (2000). Another third current specialized tests and is greatly underrepresented in text books.

The pancreas is about the size and shape of the hand; the tail points to the spleen, and the head is nestled in a loop of the duodenum. Loss of the exocrine (digestive) func tions commonly leads to severe gastrointestinal disturbances, malabsorption, a cata bolic state, and weight loss in the face of an adequate diet. Loss of endocrine pancreatic function leads to a large spectrum of disorders associated with the loss of hormone secretions; the most common and most severe is diabetes mellitus. Loss of the entire pancreas owing to trauma, surgery, atherosclerosis, or other medical problems leaves the patient in a digestive and metabolic crisis. The correct diagnosis of pancreatic disorders remains a challenge given the multi faceted function of the pancreas. The clinical laboratory plays an important role, and other tools such as CAT scans, ultrasound, radiographs, biopsies, and even surgery are used to make a diagnosis. The emphasis of Clinical Pathology of Pancreatic Disorders is on the clinical laboratory definition of pancreatic pathology. Disorders of the endocrine pancreas can be highly complex, and sophisticated tests are needed to determine the nature of the disease, its prognosis, and its optimal treat ment. Diabetes is the most common of the endocrine diseases; it presents in many ways, and has varied etiologies. We now know that the diabetes of childhood is usually an autoimmune disease, and this has a major effect on the treatment of these individuals."

In this comprehensive reference, leading researchers examine the biology, molecular biology, and diseases of the Bunyaviridae, and provide up-to-date information on the genetic characterization and variations of this virus group. The chapters deal with the molecular biology of five genera: Bunyavirus, Hantavirus, Nairovirus, Phlebovirus, and Tospovirus. The chapters examine Bunyaviridae assembly and intracelluar protein transport as well as Bunyaviridae genetics. The contributors discuss the Bunyaviridae diseases, including the hantavirus pulmonary syndrome.

Antimicrobial peptides have been the subject of intense research in the past decades, and are now considered as an essential part of the defense system in bacteria, plants, animals and humans. This book provides an update on these effector molecules of the innate immune system both for researchers who are already actively involved in the area, and for those with a general interest in the topic. The book starts with an overview of the evolution of cysteine- containing antimicrobial peptides (including defensins), and the role of these peptides in host defense in plants and micro- organisms. The realization that antimicrobial peptides also display functions distinct from their direct antimicrobial action is the focus of the next chapters, and puts these peptides center stage in immunity and wound repair. Further chapters discuss the role of antimicrobial peptides in disease, by providing an overview of mechanisms in bacterial resistance to antimicrobial peptides and a discussion of their role in inflammatory bowel disease, cystic fibrosis lung disease and chronic obstructive pulmonary disease. Finally, the book shows how knowledge of the function of antimicrobial peptides and their regulation can be used to design new therapies for inflammatory and infectious disorders. This is a very important area of research because of the increase in resistance of micro-organisms to conventional antibiotics. Therefore the use of synthetic or recombinant peptides, or agents that stimulate the endogenous production of antimicrobial peptides, provides an attractive alternative for conventional antibiotics.

The staphylococci are important pathogenic bacteria responsible for a variety of diseases in humans and other animals. They are the most common cause of hospital-acquired infection. Antibiotic resistant strains (MRSA) have become endemic in hospitals in most countries, causing major public health issues. In addition, the incidence of new strains that cause severe community-acquired infections in healthy people is increasing and MRSA strains are emerging in agricultural and domestic animals. In the race to understand staphylococcal pathogenesis, the focus has been on genetics, as a bacterium can only do what its genes allow. The publication of the first staphylococcal whole genome sequence in 2001 paved the way for a greater understanding of the molecular basis of its virulence, evolution, epidemiology, and drug resistance. Since then, the available genomic data has mushroomed and this, coupled with the major advances in genetic know-how and the availability of better genetic tools, has

Since the discovery of Australia antigen and its association with type B hepatitis, molecular characterization of the components making up hepatitis B virus (RBV) have been pursued with worldwide interest. Over the past two decades, such characterization has led to the development of sensitive assays to screen and exclude contaminated units from blood banks and has recently resulted in the licensing of several RBV vaccines. That more than 200 million people worldwide are chronically infected with RBV, and that they are at a high risk for the development of chronic hepatitis and hepatocellular carcinoma, still represent formidable problems in our understanding of host-virus relationships on the molecular level. In the absence of a suitable tissue culture system, and with a very limited host range of infection, characterization of RBV on the molecular level has made remarkable progress recently with the advent of genome cloning, sequencing and expression of individual virus genes by recombinant DNA technology. The presence of hepatitis B-like viruses in an expanding number of animal hosts, and the possibility of virus replication in cells other than hepatocytes, provide great promise that future work will elucidate the molecular mechanisms operative in the various outcomes of RBV infection.

Streptococci are Gram-positive bacteria that cause a wide spectrum of diseases, such as pharyngitis, necrotizing fasciitis and streptococcal toxic shock syndrome, as well as rheumatic fever and rheumatic heart disease as sequelae. Antibiotics alone have not been able to control the disease and in spite of many efforts an effective vaccine is not yet available. A prerequisite for novel and successful strategies for combating these bacteria is a complete understanding of the highly complex pathogenic mechanisms involved, which are analyzed in this volume. In ten chapters, prominent authors cover various aspects including streptococcal diseases and global burden, epidemiology, adaptation and transmission, and molecular mechanisms of different diseases, as well as sequelae, vaccine development and clinical management. This book will serve as a valuable reference work for scientists, students, clinicians and public health workers and provide new approaches to meeting the challenge of streptococcal diseases.

Cerebral amyloid angiopathy (CAA) is a distinctive abnormality of small cerebral blood vessels, one that has intrigued neuroscientists for decades. The time seems right for a book which examines the phenomenon of CAA using a multifaceted approach: What does it produce clinically? How might CAA be imaged? What are the crucial biochemical/cellular events within cerebral vessel walls that lead to CAA? How can in vitro or transgenic experimental systems be used to understand the etiology of, or even potential treatments for, CAA? The editors have assembled key figures in the field of CAA research to examine these (and other) questions in a series of focused chapters that address specific issues of importance in understanding CAA and its clinical manifestations. Comprehending the biology and pathogenesis of this fascinating vascular lesion may even provide clues to less common forms of cerebral microvascular disease that have been recognized for decades (hypertensive microangiopathy) or more recently (CADASIL).

Global warming and globalization are the buzzwords of our time. They have nearly reached a religious status and those who deny their existence are considered modern heretics. Nevertheless, the earth has become an overcrowded village, traversable within a single day. Thus it is hardly surprising that besides persons and goods also agents of disease are easily transported daily from one end of the world to the other, threatening the health and lives of billions of humans and their animals. Agents of diseases (prions, viruses, bacteria, fungi and parasites) are not only transmitted by body contact or direct exchange of bodily fluids, but also by means of vectors which belong to the groups of licking or blood-sucking arthropods (mites, ticks, insects) that live close to humans and their houses.

Without a doubt the recently accelerating globalization supports the import of agents of disease into countries where they never had been or where they had long since been eradicated, leading to a false sense of living on a safe island. These newly imported or reintroduced diseases called emerging diseases may lead to severe outbreaks in cases where the countries are not prepared to combat them, or in cases where viruses are introduced that cannot be controlled by medications or vaccines.

Arthropods are well known vectors for the spread of diseases. Thus their invasion from foreign countries and their spreading close to human dwellings must be blocked everywhere (in donor and receptor countries) using safe and effective measures.

This book presents reviews on examples of such arthropod-borne emerging diseases that lurk on the fringes of our crowded megacities. The following topics show that there is an ongoing invasion of potential vectors and that control measures must be used now in order to avoid disastrous outbreaks of mass diseases.

Our gut is colonized by numerous bacteria throughout our life, and the gut epithelium is constantly exposed to foreign microbes and dietary antigens. Thus, the gut epithelium acts as a barrier against microbial invaders and is equipped with various innate defense systems. Resident commensal and foreign invading bacteria interact intimately with the gut epithelium and can impact host cellular and innate immune responses. From the perspective of many pathogenic bacteria, the gut epithelium serves as an infectious foothold and port of entry for disseminate into deeper tissues. In some instances when the intestinal defense activity and host immune system become compromised, even commensal and opportunistic pathogenic bacteria can cross the barrier and initiate local and systematic infectious diseases. Conversely, some highly pathogenic bacteria, such as those highlighted in this book, are able to colonize or invade the intestinal epithelium despite the gut barrier function is intact. Therefore, the relationship between the defensive activity of the intestinal epithelium against microbes and the pathogenesis of infective microbes becomes the basis for maintaining a healthy life.

The authors offer an overview of the current topics related to major gastric and enteric pathogens, while highlighting their highly evolved host (human)-adapted infectious processes. Clearly, an in-depth study of bacterial infectious strategies, as well as the host cellular and immune responses, presented in each chapter of this book will provide further insight into the critical roles of the host innate and adaptive immune systems and their importance in determining the severity or completely preventing infectious diseases. Furthermore, under the continuous threat of emerging and re-emerging infectious diseases, the topic of gut-bacteria molecular interactions will provide various clues and ideas for the development of new therapeutic strategies.

Malaria remains an alarming emergency in developing countries. It is thus urgent to identify any parasite or host molecules that can serve as new affordable markers for early diagnosis of disease complications or as new targets for vector control. In this context, human and mosquito lysozymes are good candidate molecules, as their involvement in malaria has been recently reported by several independent groups. This book reviews the grounded knowledge on malaria etiology and physiopathology, as well as the current approaches for diagnosis, therapy, and vector control. In addition, the emerging evidence on the involvement of human and mosquito lysozymes in malaria from available experimental models and clinical studies is thoroughly discussed, as is the potential use of other antimicrobial peptides against malaria. Intriguingly, the contributors propose that old well-known molecules such as lysozymes might be used as new targets for cost-effective strategies to fight malaria.

According to the author, the book addresses to all the scientists and not only to immunologists or biologists of European countries who are engaged in developing a vaccine, or a diagnostic kit or a new drug against the infection or on schistosome evolution. Even these scientists have to visit endemic countries for field trials or ask their counterparts to collect field data (which this book addresses ). Thus this book is not on molecular fundamentals but on the infection itself; how schistosome species are responding to the drug ; sensitivity and specificity of immunodiagnostic kits, antigen molecules; snail compatibility, production losses; schistosome evolution; schistosome outbreaks; complexities where more than two schistosome species are existing; problem of human schistosomiasis in South Asia etc In fact , all the topics of great interest to international scientists and scientists of endemic countries.

This examinational prep manual for undergraduates covers everything students need to know to pass their microbiology exams. Includes a large number of diagrams and flowcharts. Appendices at the end of book include additional topics. Separate sections for vaccines and staining methods helpful for practical examinations.

In susceptible individuals, malignant hyperthermia (MH) can be triggered by various anesthetics during surgery. First described in 1960, research since then has concentrated on reducing the very high mortality rate associated with MH. Although significant progress in treatment has been made with the introduction of dantrolene sodium in 1979, many questions remain unanswered. Following on the results of more than 30 years of investigative efforts, the Third International Symposium on MH was held in Hiroshima, Japan, in 1994, immediately before the Seventh International Workshop on MH. Specialists in the field discussed the most up-to-date findings from the point of view of clinical classification, history, and incidence based on the evidence of epidemiology, diagnostic muscle testing, genetics, and biochemistry. These proceedings of the symposium present important keys to understanding the mechanism of MH and related syndromes at the genetic level and include procedures for the monitoring and care of patients. This volume will be invaluable not only for surgeons and anesthesiologists but also for physiologists and researchers.

Quantitative Real-Time PCR: Methods and Protocols focuses on different applications of qPCR ranging from microbiological detections (both viral and bacterial) to pathological applications. Several chapters deal with quality issues which regard the quality of starting material, the knowledge of the minimal information required to both perform an assay and to set the experimental plan, while the others focus on translational medicine applications that are ordered following an approximate logical order of their medical application. The last part of the book gives you an idea of an emerging digital PCR technique that is a unique qPCR approach for measuring nucleic acid, particularly suited for low level detection and to develop non-invasive diagnosis. Written for the Methods in Molecular Biology series, most chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, laboratory protocols and tips on troubleshooting and avoiding known pitfalls. Practical and authoritative, Quantitative Real-Time PCR: Methods and Protocols aims to aid researchers seeking to devise new qPCR-based approaches related to his or her area of investigation.

The stages of Blastocystis have been known for 101 years. However, many facts are still disputed, e.g. even the question whether it is a true pathogen or a commensal present in sometimes life- threatening diarrheas. The present book evaluates in chapters contributed by renowned researchers the latest findings on: * Landmarks in the discovery of Blastocystis * Epidemiology, transmission and zoonotic potential * Morphology of human and animal Blastocystis isolates * Clinical aspects of Blastocystis infections * Behavioral decision analysis: what makes us sick? * Blastocystis-host interactions * Molecular approaches on the systematical position * Genetic polymorphism * Blastocystis from a statistical point of view * Diarrheas due to different agents of disease * Zoonotic diseases in comparison As such, this book provides a broad range of information for people working in this field, for physicians and veterinarians who are confronted with clinical cases, teachers, students and technical staff members in the fields of microbiology, parasitology and diagnostic methods.

Coronaviruses were recognized as a group of enveloped, RNA viruses in 1968 and accepted by the International Committee on the Taxonomy of Viruses as a separate family, the Coronaviridae, in 1975. By 1978, it had become evident that the coronavirus genomic RNA was infectious (i. e., positive strand), and by 1983, at least the framework of the coronavirus replication strategy had been per ceived. Subsequently, with the application of recombinant DNA techniques, there have been remarkable advances in our understanding of the molecular biology of coronaviruses, and a mass of structural data concerning coronavirus genomes, mRNAs, and pro teins now exists. More recently, attention has been focused on the role of essential and accessory gene products in the coronavirus replication cyde and a molecular analysis of the structure-function relation ships of coronavirus proteins. Nevertheless, there are still large gaps in our knowledge, for instance, in areas such as the genesis of coronavirus subgenomic mRNAs or the function of the coronavirus RNA-dependent RNA polymerase. The diseases caused by coronaviruses have been known for much longer than the agents themselves. Possibly the first coronavirus-related disease to be recorded was feline infectious peritonitis, as early as 1912. The diseases associ ated with infectious bronchitis virus, transmissible gastroenteritis virus, and murine hepatitis virus were all well known before 1950."

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.
