Physiological Systems in Insects, Fourth Edition explores why insects have become the dominant animals on the planet. Sections describe the historical investigations that have led us to our current understanding of insect systems. Integrated within a basic physiological framework are modern molecular approaches that provide a glimpse of the genetic and evolutionary frameworks that testify to the unity of life on earth. This updated edition describes advances that have occurred in our understanding of hormone action, metamorphosis, and reproduction, along with new sections on the role of microbiomes, insecticide action and its metabolism, and a chapter on genetics, genomics and epigenetic systems. The book represents a collaborative effort by two internationally known insect physiologists who have instructed graduate courses in insect physiology. As such, it is the ideal resource for entomologists and those in other fields who may require knowledge of insect systems.

Astroviruses were first identified in the feces of children in 1975. Since then, they have been found in 3 to 20% of children with diarrhea. Given that serological studies have demonstrated that up to 90% of children have been exposed to at least one strain of astrovirus by age 9, the prevalence of infection may be much higher. Supporting this are studies demonstrating that astroviruses can also be isolated in a subset of asymptomatic individuals, suggesting that a proportion of infected individuals shed the virus asymptomatically or for some time after the resolution of other symptoms of infection. Asymptomatic carriers may be a major reservoir for astroviruses in the environment and could contribute to dissemination of the virus. Astroviruses are extremely stable in the environment and can be transmitted nosocomially, directly from infected individuals and potentially animals, and through contaminated food and water. Although typically an acute disease, astrovirus infection in premature infants may be associated with the development of necrotizing enterocolitis and in new-onset celiac disease in children. Immunocompromised children are even more susceptible often developing persistent infections that lead to wasting or even systemic infections associated with fatal encephalitis. In spite of its importance, little is known about astrovirus pathogenesis, molecular biology, epidemiology, or cell biology. The goal of this book is to provide the latest and most up-to-date information on this medically important and rapidly evolving group of viruses. It will include sections on the history of astroviruses and their disease in humans; information on viral replication and immune responses; new information on how astroviruses induce disease including the expression of a viral enterotoxin regulating intestinal epithelial cell tight junctions, the isolation and identification of new astrovirus genotypes in mammals including humans, and astroviruses of veterinary importance. Finally, the book will also introduce the complexity of astrovirus epidemiology and potential as an important new zoonotic disease, and its role in food-borne disease. This will be the first book of its kind and will be of great interest to microbiologists, virologists, infectious disease specialists, immunologists, pediatricians, public health and food safety experts, veterinarians, poultry industry specialists, and researchers and clinicians interested in enteritis.

A decade has passed since Drs. Hoch and Silhavy edited their comprehensive work entitled Two-Component Signal Transduction. This fascinating book encour- aged many microbiologists and students to enter the new worldofsignal transduction in microbiology. In 2003, Dr. Inouye edited Histidine Kinase in Signal Transduc- tion, which focused on histidine kinases and presented the wealth ofinformation accumulated on this protein family. Bacteria usually possess a numberofTwo-Component Systems (TCSs), rang- ing from a few to over 100. InE. coli, 29 histidine kinases, 32 response regulators, and 1histidine-containing phosphor transmitter (HPt) domain have been found by analyses ofthe K-12 genome. Several examples ofin vitro and in vivo cross-talks and signal transductioncascadesbetweenTCSs inE. coli have beenreported,which suggests the existence ofa TCS network (Chapter 1). Interactions among different TCSs enable one system to respond to multiple signals, which is important for bacteria to minutely adjust themselves to complex environmental changes. Such interactions are found or predicted in various bacteria in this book. Many ofthese interactions might be connected by small proteins such as B1500(Chapter 1)and PmrD (Chapter2). More examplesofsuch proteins should be identified in the near future in order to fill-in the missing parts ofthe bacterial signal transduction network, a new paradigm that is increasingly recognized as the signal transduction pathway in bacterial cells. For drug discovery, this pathway is consideredas important as the signal transductionpathway in animal cells (Chapters 15 and 16).

This book aims to bridge the gap in understanding how protein-tyrosine phosphatases (PTPs), which carry out the reverse reaction of tyrosine phosphorylation, feature in cancer cell biology. The expertly authored chapters will first review the general features of the PTP superfamily, including their overall structure and enzymological properties; use selected examples of individual PTP superfamily members, to illustrate emerging data on the role of PTPs in cancer; and will review the current status of PTP-based drug development efforts. Protein Tyrosine Phosphatases in Cancer,from renowned researchers Benjamin Neel and Nicholas Tonks, is invaluable reading for researchers in oncology, stem cell signaling,and biochemistry.

Written in the successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls.Authoritative and accessible, Avian Influenza Virus, Second Edition seeks to serve both professionals and novices with its well-honed methodologies in an effort to further our knowledge of these important pathogens.

The notion that contaminated environments in hospital settings significantly contribute to the risk of an individual acquiring an infection while hospitalized is continuously gaining recognition by the medical community. There is a clear correlation between the environmental bioburden present in a clinical setting and the risk of patients acquiring an infection. Thus using self-disinfecting surfaces can be a very important adjunct in the fight against nosocomial pathogens.

This book reviews the increasing evidence that contaminated non-intrusive soft and hard surfaces located in the clinical surroundings are a source of nosocomial pathogens and focuses on the utility of copper containing materials in reducing bioburden and fighting hospital acquired infections. It also reviews other biocidal surface alternatives and the economics of using biocidal surfaces in a hospital environment. Finally, it discusses the pros and cons of existent disinfection modalities other than biocidal surfaces.

Molecular Diagnostics in Dermatology and Dermatopathology presents the basics of molecular biology and molecular diagnostic methods most commonly used in the clinical laboratory, with an emphasis on the concepts and testing most relevant to dermatological diseases. Topics include the integration of newer diagnostic and prognostic techniques with traditional histologic approaches, and discussions of regulatory, ethical, legal, economic issues and newer technologies. This important diagnostic tool outlines the clinically relevant uses (i.e.; diagnostic, staging and/or prognostic) applications of these techniques in the field of dermatology. Molecular studies that investigate the pathogenesis of skin diseases will be excluded, unless they also have a direct diagnostic utility. The book will be of interest to practicing pathologists, dermatology and pathology residents, dermatologists, and dermatopathologists."

Mast cells are versatile, tissue-homing secretory cells, which were first described by Paul Ehrlich in 1878. Mast cells have long been implicated in the pathogenesis of allergic reactions and certain protective responses to parasites. Their functional role, however, has been discovered to be increasingly complex and multifarious. Mast cells have been implicated in various cell-mediated immune reactions, being found in tissues from multiple disease sites, and as a component of the host reaction to bacteria, parasite, and even virus infections. They have also been shown to participate to angiogenic and tissue repair processes after injury. The importance of a possible functional link between chronic inflammation and cancer has long been recognized. As most tumours contain inflammatory cell infiltrates, which often include plentiful mast cells, the question as to the possible contribution of mast cells to tumour development has progressively been emerged. In this book, the general biology of these cells, their development, anatomical distribution and phenotype as well as their secretory products will first be discussed. The biology of tumour cells, their structural and molecular characteristics, the specificity of the tumour microenvironment and the development of a vascular network in the tumour context will be analyzed. The involvement of mast cells in tumour biology and tumour fate will then be considered, with particular emphasis on the capacity of these cells to stimulate tumour growth by promoting angiogenesis and lymphangiogenesis. The last chapter suggest that mast cells may serve as a novel therapeutic target for cancer treatment.

The currently available means of combating fungal infections are weak and clumsy. The application of fungal genomics offers an unparalleled opportunity to develop novel antifungal drugs. Interestingly, several novel antifungal drug targets have already been identified and validated. However, it is premature to expect a novel antifungal agent in clinical setting as drug discovery programs are still in their infancy. In addition to classical and genomic approaches to drug discovery, treasure trove based on natural products and phytomedicine can provide a multitude of alternative modes of combating fungal infection. This book incisively addresses essential topics on various aspects pertaining to fungal diseases in human and animals, their reservoir, fungal pathogenesis, their management and recent advances in their treatment. Issues of antifungal drug toxicity, especially nephrotoxicity, are also discussed. The development of resistance in fungal pathogens, including multidrug resistance and its mechanism, is dealt with in two chapters. Diverse diagnostic approaches to fungal infections are also reviewed. The combinational drug strategies used in combating invasive fungal infections are addressed in detail. The management of pulmonary mycoses in stem cell transplantation is also given special focus. Novel antifungal drugs (synthetic and herbal), fungal vaccines, and metabolic pathways as drug targets are discussed in detail in three different chapters. Subsequently the roles of innate immunity, cytokine therapy and immunomodulators in the treatment of fungal infections are elaborated upon. As novel drug delivery systems have a great potential for modifying the pharmacokinetics of medications, the last chapter takes this fact into consideration in its examination of state-of-the-art delivery systems in controlling fungal infections.

The study of viruses necessarily involves dissecting the intimate details of cellular pathways. Viruses have often been employed as tools in studying cellular pathways, as was done by early retrovirologists such as Peyton Rous in attempting to understand the mechanism of cellular transformation and oncogenesis. On the other side of the coin, virologists seek to de?ne those cellular elements interacting intimatelywiththeir virus ofinterestinorder to better understand viral replication itself, and in some cases to develop antiviral strategies. It is in the intersection of virology and cell biology that many of us ?nd the most rewarding aspects of our research. When a new discovery yields insights into basic cellular mechanisms and presents new targets for int- vention to ?ght a serious pathogen, the impact can be high and the excitement intense. HIV has been no exception to the rule that viruses reveal many basic aspects of cellular biology. In recent years, in part because of the importance of HIV as a major cause of human suffering, numerous cellular processes have been elucidated through work on processes or proteins of this human retrovirus. The excitement in this ?eld is especially well illustrated by the discovery of new innate means of resisting viral replication, such as the work on APOBEC3G, TRIM5a, and BST-2/ tetherin presented in this volume.

Recent studies have shown that cells from adipose tissue are capable of trafficking to tumors, thus enabling paracrine action of adipokines from within the tumor microenvironment. Increased tumor vascularization, immune system suppression and direct effects on malignant cell survival and proliferation have been investigated as mechanisms regulated by adipokines. The goal of this book is to discuss data pointing to the role of adipose tissue in cancer and to dissect individual mechanisms through which adipose tissue excess or restriction could influence cancer progression.

Multiple demographic or economic parameters contribute to the origin of emerging infections, for example: poverty, urbanization, climate change, conflicts and population migrations. All these factors are a challenge to assess the impact (present and future) of parasitic diseases on public health. The intestine is a major target of these infections; it is a nutrient-rich environment harbouring a complex and dynamic population of 100 trillion microbes: the microbiome. Most researches on the microbiome focus on bacteria, which share the gut ecosystem with a population of uni- and multi cellular eukaryotic organisms that may prey on them. Our interest focuses on the families of eukaryotic microbes inhabiting the intestine, called "intestinal eukaryome", that include fungi, protists and helminths. Knowledge on the reciprocal influence between the microbiome and the eukaryome, and on their combined impact on homeostasis and intestinal diseases is scanty and can be considered as an important emerging field. Furthermore, the factors that differentiate pathogenic eukaryotes from commensals are still unknown. This book presents an overview of the science presented and discussed in the First Eukaryome Congress held from October 16th to 18th, 2019 at the Pasteur Institute in Paris. This book covers the following topics: Phylogenetic, prevalence, and diversity of intestinal eukaryotic microbes; and their (still enigmatic) historical evolution and potential contributions to mucosal immune homeostasis. Integrative biology to study the molecular cell biology of parasite-host interactions and the multiple parameters underlining the infectious process. The exploitation of tissue engineering and microfluidics to establish three-dimensional (3D) systems that help to understand homeostasis and pathological processes in the human intestine.

Giardia duodenalis (=G. lamblia), Entamoeba histolytica, Cryptosporidium parvum and Cyclospora cayetanensis are more than just a mouthful for most who might encounter them. These protozoan parasitic agents contribute significantly to the staggering caseload of diarrheal disease morbidity encountered in developing world nations. Compounding the issue of their mere presence is the fact that standard ova and parasite exams frequently do not detect these infections. Detectable stages may be shed intermittently or require specialized staining procedures. Added to this is the often large number of asymptomatic carriers who serve as reservoirs for infecting others. These parasites are also not strangers to more developed nations, having responsibility for both small and large-scale disease outbreaks. In such settings they may be even more difficult to detect simply because they are frequently overlooked in the grand scheme of disease causing possibilities. They share common features; all are Protozoa, all possess trophic stages that inhabit the gastrointestinal tract, all have the ability to produce disease and in some instances death, and all produce environmentally stable cysts or oocysts, which ensure their transmissibility. In other ways, these organisms are profoundly different. Giardia is a flagellate that inhabits the gut lumen in close association with enterocytes. Entamoeba is an amoeba that preferentially inhabits the mucosal region of the gut lumen, but which may, under certain circumstances, become invasive. Cryptosporidium and Cyclospora are obligate intracellular coccidians, each taking up a unique niche within their respective host enterocytes.

New experimental observations often require fresh concepts for their interpretation, and at times even changes of paradigms. This is the situation with the recent realization that circulating endothelial progenitor cells may have an important contribution to the maintenance and formation of new endothelium in adult organisms, in a surprisingly wide variety of situations. The classical paradigm of angiogenesis, centered on the notion of "sprouting" can hardly accommodate them. It was previously realized that it needs to be "stretched out" to include alternative mechanisms of microvascular development, such as intussusception and capillary fusion. However, a major debate where to reconsider the sprouting mechanism, and to promote alternative views, did not take place yet. The number of publications in this field increased exponentially in the last years. Nevertheless, the concepts and notions so much needed to describe and to explain the new observations are still scarce, and heterogeneous. Within the larger community dedicated to the study of angiogenesis, the researchers involved in investigation of circulating precursor endothelial cells biology represent a subgroup with specific preoccupations and opinions. Many of them did not meet each other so far, and no major scientific events have been dedicated before exclusively to their interests. For the above reasons, the idea to organize a symposium addressing the new developments in angiogenesis research was received with enthusiasm by all those involved in its preparation.

Since their discovery in the 1960s, methicillin-resistant S. aureus (MRSA) strains continue to present unique challenges to clinicians, microbiologists, and molecular biologists around the world. These organisms are typically resistant to several other antimicrobial agents, including aminoglycosides, chloramphenicol, clindamycin, fluoroquinolones and macrolides and are susceptible only to vancomycin. In fact there is increasing evidence that this susceptibility will soon disappear. In this book, internationally renowned authors comprehensively review all aspects of MRSA research. Topics covered include strategies for the detection and typing of MRSA strains, epidemiological characterisation, molecular evolution of MRSA, vancoymcin resistant S. aureus, mechanisms of methicillin resistance, virulence mechanisms in MRSA pathogenesis, recommended treatment of MRSA infections, and options for the prevention and control of MRSA infections.

Sendai virus (SeV) is not just a mouse pathogen but is evolving into a cutting-edge component of biotechnology. SeV reverse genetics originating from a pure academic need to settle long-held questions in the biology and pathogenicity of nonsegmented negative strand RNA viruses (Mononegavirales) is about to bear the impressive fruit of multipurpose cytoplasmic (non-integrating) RNA vectors. This book brings together in one source the SeV biology revealed by conventional approaches and reverse genetics, the methods to construct the first-generation SeV vector and to generate safer versions, and the applications in medical settings that have left or are about to leave the laboratory bench. The applications, which already are diverse and have high medical impact, include use as vaccine vectors against AIDS and respiratory virus infections, creation of BioKnife to resect malignant tumors, induction of "footprint (transgene) free" pluripotent stem cells, and gene therapy for peripheral arterial disease. These achievements-which are just a few of many examples-were attainable only after rigorously incorporating the rich knowledge of SeV biology that has accumulated during the several decades since the discovery of the virus. Application of SeV vector is certain to expand greatly because of its extremely high performance in transgene expression and its remarkable target cell breadth.
