Interferons (IFNs) play pivotal roles in shaping the immune responses in mammals and are particularly important for the control of viral infections, cell growth, and immune regulation. These proteins rapidly induce an anti-viral state in cells that surround infected cells. In order to survive, viruses have evolved with multiple strategies to evade the anti-viral effects of IFNs. Elucidating the molecular and cellular biology of the virus-interferon interaction is key to understanding issues, such as viral pathogenesis, latency, and the development of novel antivirals. In this book, international experts review current research topics, producing a timely overview of this exciting field. The book opens with a chapter that comprehensively reviews the antiviral effects of extracellular double-stranded RNA - the viral toxin. This is followed by chapters that review the properties of type I and type III interferons, and the role of interferon-stimulated genes. Additional chapters are devoted to understanding the diverse strategies used by clinically-relevant human viruses to subvert host interferon responses. The book closes with an interesting overview of the clinical application of interferons as antiviral and anticancer agents. It will be essential reading for every scientist involved in interferon or antiviral research and will be a recommended text for all virology laboratories.

Saliva as a unique sample for health assessment is gaining attention among researchers of different fields in the last 20 years; being reflected in an impressive increase in the number of papers published studying saliva from different biological aspects in human and veterinary species. Once deemed merely a digestive juice is now considered a biological fluid capable of communicating information about physiopathological processes occurring in organisms, since saliva has been shown to contain molecular and bacterial compounds that can change in response to local and systemic pathologies. Furthermore, the interest of saliva as a diagnostic, prognostic and monitoring biofluid is forced by its non-invasive nature being of easy and inexpensive sampling, involving only minimal discomfort and allowing the collection of multiple/repeated specimens at anytime, anywhere and without need for specialized staff. In this contributed volume, the authors bring together, summarize and reflect the generated knowledge about saliva as a source of biomarkers for health and welfare evaluation in humans and animal models. This volume also highlights the importance of confounding factors, such as sampling methods, flow, total protein content, contamination, or storage. This book will serve as a manual for graduates, practitioners and researchers by providing general ideas about the possibilities and utilities of saliva in clinical practice or investigation, and indicating the main cautions each should have in mind before saliva usage.

This book systemically presents the latest research on lectins, covering all the major topics in the field, including the heterocomplex of lectins and Toll-like receptors, protective versus pathogenic functions in connection with microbial infections, and novel strategies for enhancing host immunity against infectious diseases caused by viruses, bacteria, and fungi. Lectins are a large group of glycan-binding proteins that recognize diverse glycan and non-glycan structures expressed on prokaryotic and eukaryotic cells, and are vital to cell-cell interactions, the attachment of microbes to host cells, and the recognition and activation of immune responses to exogenous and endogenous danger signals. The composition and structure of microbes are complex and include numerous 'pathogen-associated molecular patterns' or 'damage-associated molecular patterns'. As such, microbes' interactions with immune cells activate multiple innate immunity receptors and produce distinct inflammatory reactions, which can be protective to contain microbial invasion, or pathogenic to cause tissue damage and shock syndrome in the host. The book shares lessons learned from state-of-the art research in this field, highlights the latest discoveries, and provides insightful discussions on lectin-mediated inflammatory reactions, while also outlining future research directions.

Hormonal influences, both natural and iatrogenic, are implicated in the most frequent health issues of women. Endometrial cancer is now the most common gynecologic cancer in the United States and the industrialized world. This cancer is strongly related to hormonal and metabolic factors. In addition, breast cancer treated with hormone therapy (Tamoxifen) may, in some cases, be associated with uterine pathology. Hormone therapy is used to improve the physiological effects and counteract abnormal and deleterious effects of "natural" hormonal activity. Millions of women receive hormone therapy at some point of their life: using oral contraceptives, reproductive technology, treatment for post-menopausal symptoms, among other uses. This book addresses a range of women's health issues, from fertility to neoplasms, and their relationship with natural and iatrogenic hormonal effects. Chapters include clinical and pathological descriptions, theoretical and practical medical issues, and original studies and cases. Controversial issues in certain hormone therapies are presented with updated concepts based on clinical studies and novel statistical methods. The book will be useful for specialized and general physicians, oncologists, endocrinologists, researchers, medical students, and others in the field of women's health.

The novel coronavirus 2019 (COVID-19) has caused a serious global pandemic in just eight months. Nearly every country and territory in the world has been affected by the virus.

As the peak begins to slow in many countries, the death rates remain high amidst justified fears of a second wave. A rapid worldwide mobilization has begun to identify effective treatments and develop vaccines. 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 the effects of the virus in cases of co-morbidities, new treatment approaches, 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.

Alphaherpesviruses are a fascinating group of DNA viruses that include important human pathogens, such as herpes simplex virus type 1 (HSV-1), HSV-2, and varicella-zoster virus (VZV) - the causative agents of cold sores, genital ulcerous disease, and chickenpox/shingles, respectively. A key attribute of these viruses is their ability to establish lifelong latent infection in the peripheral nervous system of the host. Such persistence requires subversion of the host's immune system and intrinsic antiviral defense mechanisms. Understanding the mechanisms of the immune evasion and what triggers viral reactivation is a major challenge for today's researchers. This has prompted enormous research efforts into understanding the molecular and cellular biology of these viruses. This up-to-date and comprehensive study distills the most important research in this area, providing a timely overview of the field. Topics include: transcriptional regulation, DNA replication, translational control, virus entry and capsid assembly, the role of microRNAs in infection, and oncolytic vectors for cancer therapy. In addition, there is coverage of virus-host interactions, including apoptosis, subversion of host protein quality control and DNA damage response pathways, autophagy, establishment and reactivation from latency, interferon responses, immunity, and vaccine development. This is essential reading for everyone working with alphaherpesviruses and will be of interest to all virologists working on latent infections.

This book provides an up-to-date review of fasciolosis, a disease caused by Fasciola hepatica and Fasciola gigantica, including its biology, transmission, epidemiology, host distribution, economic impact, and novel approaches for its diagnosis, treatment and prevention. It first offers a brief overview of the history of the disease, the genetic diversity of the parasite and its distribution, and the ecology of the vector snail, which belongs to the Lymnaeidae/Planorbidae family. It also examines the current strategies and novel approaches for controlling the parasite, diagnosing infections and vaccine development. Importantly, it highlights issues relating to the control of fasciolosis, including drug resistance, lack of effective diagnostics, and the parasite's long-term survival strategies based on regulation and modulation of the host immune system. Lastly, it discusses the novel control snail vectors using bait formulations, and synergetic and phototherapy treatment with chlorophyllin, which does not kill the vector.

Of the 758 species of hard ticks (family Ixodidae) currently known to science, 137 (18%) are found in the Neotropical Zoogeographic Region, an area that extends from the eastern and western flanks of the Mexican Plateau southward to southern Argentina and Chile and that also includes the Greater and Lesser Antilles and the Galapagos Islands. This vast and biotically rich region has long attracted natural scientists, with the result that the literature on Neotropical ticks, which are second only to mosquitoes as vectors of human disease and are of paramount veterinary importance, is enormous, diffuse, and often inaccessible to non-specialists. In this book, three leading authorities on the Ixodidae have combined their talents to produce a summary of essential information for every Neotropical tick species. Under each species name, readers will find an account of the original taxonomic description and subsequent redescriptions, followed by an overview of its geographic distribution and host relationships, including a discussion of human parasitism. Additional sections provide detailed analyses of tick distribution by country and zoogeographic subregion (the Caribbean, southern Mexico and Central America, South America, and the Galapagos Islands), together with a review of the phenomenon of invasive tick species and examination of the many valid and invalid names that have appeared in the Neotropical tick literature. The text concludes with an unprecedented tabulation of all known hosts of Neotropical Ixodidae, including the tick life history stages collected from each host. This book is an invaluable reference for biologists and biomedical personnel seeking to familiarize themselves with the Neotropical tick fauna.
