The nucleotide sequence of the gene from which messenger RNA mole cules are transcribed is in a form that can be translated by cellular ribosomes into the amino acid sequence of a particular polypeptide, the product of the gene. The discovery of messenger RNA more than twenty years ago led to a series of studies on its organization and function in cells in the presence of infecting viruses. This volume is devoted to current studies in the field of cellular and viral messenger RNA. The studies presented provide an insight into molecular and genetic aspects of messenger RNA. Special attention was paid by the authors to the molecular organization of mRNA species, to the processing of mRNA molecules, and to the different strategies employed by DNA and RNA viruses in the synthesis of their mRNA. The ability of a virus to take over the protein-synthesizing mechanisms of an infected cell depends on its ability to produce mRNA molecules which can affect the host mRNA or utilize cellular components more efficiently. The differences between, and similarities of, the strategies of mRNA synthesis devised by various DNA and RNA viruses are described herein. This book should be of interest to all students of cellular and viral genes and scientists in the field. It is suitable as a textbook for workshops and courses on mRNA. I wish to thank the authors for their fine contributions and for their interest."

This volume gives the latest developments in on the mechanisms of cancer cell resistance to apoptotic stimuli, which eventually result in cancer progression and metastasis. One of the main challenges in cancer research is to develop new therapies to combat resistant tumors. The development of new effective therapies will be dependent on delineating the biochemical, molecular, and genetic mechanisms that regulate tumor cell resistance to cytotoxic drug-induced apoptosis. These mechanisms should reveal gene products that directly regulate resistance in order to develop new drugs that target these resistance factors and such new drugs may either be selective or common to various cancers. If successful, new drugs may not be toxic and may be used effectively in combination with subtoxic conventional drugs to achieve synergy and to reverse tumor cell resistance. The research developments presented in this book can be translated to produce better clinical responses to resistant tumors.

Caroline HA(c)bert and a panel of key experimentalists and clinical investigators comprehensively review the state-of-the-art in the chemokine field, ranging from the effects of chemokines and their receptors in retroviral infections, to their role in inflammation, angiogenesis/angiostasis, and tumor cell biology. The book examines in detail fifteen recently identified chemokines and elucidates the role of chemokine function in vivo from animal experiments. Animal models are also used to explore how chemokines operate in a variety of chronic and acute inflammatory diseases and in noninflammatory processes. A detailed review of the emerging role of chemokines in viral biology is also presented, with emphasis on HIV biology and novel therapeutic possibilities. Chemokines in Disease: Biology and Clinical Research summarizes the rapidly expanding knowledge of a dazzling array of chemokines and provides fresh insights into the development of powerful new drugs for treating a wide spectrum of diseases.

And section VII details new methodologies in glycol-synthesis and lectin-carbohydrate binding assays and strategies for treatment as crucial applications.

The emergence of bacteria resistant to multiple antibiotics has become a serious threat to public health and is considered one of the greatest challenges for contemporary medicine. Phage therapy - the use of bacteriophages as anti-bacterial agents - may offer an alternative treatment for bacterial infections. Phages have many potential applications in human medicine, as well as in dentistry, veterinary science, agriculture, and food protection. Written by internationally recognized experts from leading centers involved in phage research and phage therapy, this book provides comprehensive coverage of the topic with a focus on current research and emerging applications. The book opens with chapters covering the general characteristics of bacteriophages and the basic concepts of phage therapy. Further topics include: the pharmacology of phage therapy * bacterial resistance * non-bactericidal effects of phages * main applications of bacteriophages in clinical medicine * plant pathosystems * animal production * food protection * biofilm control * regulatory and intellectual property aspects of phage therapy. Although the book focuses on applications of virulent bacteriophages, it also discusses genetically-engineered phages, phages as delivery vehicles for other antimicrobials, as well as phage lysins. It will be an essential reference for anyone interested in phage therapy, antibacterial resistance, antimicrobial development, bacteriophage research, biocontrol, and biodetection.

This book documents and presents new developments in the study of amebiasis, one of the neglected tropical diseases. Nearly 50 million people worldwide are infected with the pathogen Entamoeba histolytica, causing large-scale morbidity and mortality particularly in developing countries.

The subjects covered range from genomics and molecular and cell biology to drug resistance and new drug development, highlighting major advances in recent years in our understanding due to rapid progress in genomic and other biomedical technologies, such as visualization of molecular processes. Most of the chapters provide recent information based on latest publications. A few chapters describe some of the critical methodological issues that will be helpful for students and researchers interested in getting into the field. The contributing authors include almost all the active researchers and clinicians from around the world. This book will be a useful primary material and a valuable source of information for anyone interested in understanding amebiasis, its diagnosis, and treatment. It will also be useful to those who are interested in learning about the biology of early branching eukaryotes and protist pathogens.

This book focuses on immune reactions and interactions of humans with Helicobacter pylori - a human pathogen connected to gastritis, peptic ulcers and even gastric cancer. With nearly half of the world's population colonized, it has been characterized as one of the most successful pathogens for more than 100,000 years of co-evolution with its host. The respective chapters discuss not only how H. pylori infection is considered a paradigm for persistent bacterial infection and chronic inflammation, but also how the infection might be connected to host protection against gastro-esophageal diseases, asthma, and other allergic disease manifestations. Readers will gain essential insights into the roles of specific factors in the immune response and learn about the impact of genetic polymorphisms on the risk of gastric carcinogenesis. In addition, the book discusses the strategies used by this bacterium, which allow it to colonize specific sites in the stomach, interact with the microbiome, evade immune surveillance and undermine the resolution of inflammation during persistent infection. This volume presents a concise summary of recent advances in the areas of induction, resolution and escape of inflammation, innate and adaptive immunity, gastric disease development, as well as treatment and vaccination against H. pylori. Accordingly, it offers a valuable asset for scientists and clinicians alike.

The purpose of this review is to examine the potential role of molecular mimicry in the pathogenesis of human T-lymphotropic virus type 1 ((HTLV- 1)-associated myelopathy/tropical spastic paraparesis (HAM/TSP)). Comp- hensive reviews on the pathogenic mechanisms of HTLV-1-associated human diseases are available throughout the medical literature (Bangham 2000,, 2003; Barmak et al. 2003; Jacobson 2002; Levin and Jacobson 1997; Nagai and Osame 2003; Osame 2002). Approximately 25 years ago the ?rst human retrovirus, HTLV-1, was isolated (Poeisz et al. 1980). Subsequently, infection with HTLV-1 was shown to cause adult T-cell leukemia (ATL) and HAM/TSP (Gessain et al. 1985; McFarlin and Blattner 1991; Osame et al. 1986; Poeisz et al. 1980; Yoshida et al. 1987). HTLV-1 may infect up to 30% of people in endemic areas and 10-20 million people worldwide (Barmak et al. 2003; Edlich et al. 2000). However, only 1%-5% develop either ATL or HAM/TSP, the remainder being clinically asymptomatic carriers of HTLV-1 (Bangham 2000, 2003; Barmak et al. 2003; Jacobson 2002; Levin and Jacobson 1997; Nagai and Osame 2003; Osame 2002). Why infection with HTLV-1 causes ATL or HAM/TSP in some people while the vast majority of individuals are asymptomatic is largely - known. Some possible factors that may differentiate the asymptomatic from the diseased state include viral strain, human histocompatibility leukocyte antigen (HLA), viral load, and the immune response (Bangham 2000, 2003; Barmak et al. 2003; Jacobson 2002; Levin and Jacobson 1997; Nagai and Osame 2003; Nagai et al. 1998; Niewiesk et al. 1994; Osame 2002).

This book gives a detailed yet clear insight into the current state of the art of the therapeutic application of bacteriophages in different conditions.

The HIV pandemic continues to levy a heavy burden on the human race world-wide. The estimated number of people who became newly infected with HIV in 2009 was 2.6 million; most of these individuals live in Sub-Saharan Africa, followed by India and Southeast Asia. An estimated 370,000 new cases of pediatric infections occurred globally in 2009 (or more than 1,000 new infections every day), practically all of them through mother-to-child transmission. Up to 40% of all new infant HIV infections occur during breastfeeding. While breastfeeding by HIV-infected mothers is not recommended in the U.S. and other resource-rich settings where safe replacement feeding is easily available, the situation is different in many resource-limited settings, where replacement feeding is not safe or available and carries a high risk of infections (diarrhea, pneumonia) and infant malnutrition. Mothers in such settings are faced with a difficult dilemma: to breastfeed their infants in order to provide their infants with its many benefits (nutritional, immunologic, cognitive), but to also risk transmitting HIV. These challenges have prompted an intensive search for new prophylactic and therapeutic strategies in order to prevent infants from acquiring HIV infection through breastfeeding. In this book, expert HIV researchers critically review every aspect of this highly evolving and topical subject. The opening chapters deal with the epidemiology, global magnitude and biologic mechanisms of HIV-1 transmission from mother to child through breastfeeding and include considerations of the virus (quantity, compartments, characteristics) and the host (genetic, immunity-innate, cellular, humoral). The effects of breastfeeding on the HIV-infected mother's health and nutritional status, and the social and cultural issues associated with the practice of breastfeeding are also discussed. The next few chapters provide cutting-edge reviews of the latest approaches to prevention of HIV transmission to the infant through breastfeeding, including antiretroviral strategies, nutritional and immune-based approaches, and treatment of expressed breast milk. The remaining chapters provide a fascinating review of the many iterations this subject has received, as reflected in the several different sets of guidelines for infant feeding by HIV-infected mothers issued by the World Health Organization, and a debate by leading scientists on whether HIV-infected mothers should breastfeed their infants-in resource-limited and in resource-rich settings. A comprehensive overview of the current state of implementing the new evidence for prevention of breastfeeding transmission of HIV all over the world is also presented. Essential reading for the many disciplines of scientists and clinicians working on HIV/AIDS and other retroviruses, pediatricians, obstetricians/gynecologists, as well as all health-care professionals interested in expanding their understanding on the subject.

The technique of in situ hybridization, in its various forms, has been used routinely in many laboratories for a number of years. In the post-genome era, gene arrays and proteomics have allowed us to identify hitherto unknown unrecognized pathways and mechanisms. However, rather than diminish the importance of in situ hybridization, the now widespread use of screening te- nologies has increased the need to temporally and spatially localize the dist- bution of mRNA expression. Our intention, in In Situ Hybridization Protocols is to provide ample inf- mation for novices planning to set up the in situ hybridization technique and use it in their laboratory for the first time, as well as giving updates of recent developments for those laboratories where in situ hybridization techniques are already in use. Despite its widespread significance, in situ hybridization has retained a re- tation as one of the more difficult and capricious molecular biological te- niques. This may in part be because of the hybrid nature of the technique, which often requires a mixture of molecular biological and histological skills. The two techniques are usually taught and acquired in different streams of biolo- cal science. The step-by-step and detailed protocols provided in In Situ Hybridization Protocols by researchers active in the field should make it p- sible for both the molecular biologist with little experience of histology and the histologist with little experience of molecular biology to use the technique s- cessfully in their laboratories.

Nearly ten years after the first edition of Water-Related Death Investigation: Practical Methods and Forensic Applications, water death cases continue to be improperly investigated. The pathologist's report can determine the cause of death as a drowning, but the manner of death is the most challenging to prove. The report will not determine if a victim jumped into the water to commit suicide, fell into the water accidentally, or was pushed in as a homicidal act. Many drowning cases do not reflect injury to the body, so evidence collected at the scene plays a vital role. The importance of an on-scene body assessment cannot be overemphasized. Often, the body evidence begins to change rapidly upon recovery and may not be present during an autopsy. Written statements on the scene are an effective tool to use to determine the accuracy of information given to arriving officers. These statements need to be written by the witnesses themselves as well as the reporting person. The "Show Me" technique can also help reveal discrepancies in a person's version of what occurred as well as aid in providing the most details to an incident as is humanly possible. This second edition includes updated information on the latest technology to assist water death investigators. Parabon Snapshot can help determine the faceless identity of skeletal remains and help locate potential suspects using the science of DNA. Drones can aid in locating missing persons as well as human remains, even months after death. Updated information is provided regarding fingerprints from submerged objects, and Carbon-14 can help determine the origin of a found corpse. Key Features: Thoroughly reviews the physiological aspects of drowning Reveals the investigative characteristics inherent to various scenes of water-related deaths Highlights certain "red flag" indicators that may point to foul play or scene staging Outlines autopsy protocols, trial preparation, and expert witness testimony Provides numerous case studies and numerous illustrations to further clarify key points presented in the text Coauthored by a Master Water Death Investigator and an experienced forensic pathologist, Water-Related Death Investigation: Practical Methods and Forensic Applications, Second Edition merges the essentials of evidence collection and field investigation with autopsy best practices and laboratory testing. It will continue to serve as a valuable resource for the various professionals involved in these cases.

Continuous genetic variation and selection of virus subpopulations in the course of RNA virus replications are intimately related to viral disease mechanisms. The central topics of this volume are the origins of the quasispecies concept, and the implications of quasispecies dynamics for viral populations.

More than 40,000 species of mites have been described, and up to 1 million may exist on earth. These tiny arachnids play many ecological roles including acting as vectors of disease, vital players in soil formation, and important agents of biological control. But despite the grand diversity of mites, even trained biologists are often unaware of their significance. Mites: Ecology, Evolution and Behaviour (2nd edition) aims to fill the gaps in our understanding of these intriguing creatures. It surveys life cycles, feeding behaviour, reproductive biology and host-associations of mites without requiring prior knowledge of their morphology or taxonomy. Topics covered include evolution of mites and other arachnids, mites in soil and water, mites on plants and animals, sperm transfer and reproduction, mites and human disease, and mites as models for ecological and evolutionary theories.

There has been emergence of multidrug resistance problem all over the world due to overuse or underuse of antibiotics. Most microbes including bacteria, fungi, protozoans and others have developed resistance to antibiotics, and therefore, this problem is now recognized to be of global concern. Ubiquitous occurrence of multidrug-resistant bacteria decreases effectiveness of current treatment, which results in thousands of deaths all over the world. Hence, investigations for new alternatives and novel strategies are urgently needed to address the problem of multidrug resistance. The antimicrobial potential of essential oils and metallic nanoparticles represent an effective solution for microbial resistance. Moreover, the use of essential oils in combination with metallic nanoparticles may exert synergistic antimicrobial effects and would be a novel approach. Essential oils (EOs) are volatile, natural, aromatic oily liquids that can be obtained from several parts of plants especially the aerial ones such as leaves and flowers. They are derived from complex metabolic pathways in order to protect plants from diverse pathogenic microorganisms. In fact, the bioactivity of EOs have been confirmed by several studies which have demonstrated their antibacterial, antiviral, anti-inflammatory, antifungal, antimutagenic, anticarcinogenic, and antioxidant properties. Nanotechnology is one of the most important and emerging technologies, which has brought about a technological revolution in the world. It has enormous applications in the field of medicine. Nanoparticles are very important tools in curing different diseases in general and microbial diseases in particular due to their significantly novel and improved chemical, physical and biological properties and high surface area-to-volume ratio. Among these, metal nanoparticles are known to play pivotal role in various biomedical applications. In this context, nanoparticles such as silver have shown their potential and could emerge as the new generation of antimicrobials. Silver nanoparticles have broad-spectrum biological activities and hence are used in many biomedical applications. The various biomedical applications of silver nanoparticles include treatment of wounds, burns, in water-disinfecting systems, in nanobased bone implantations, in dentistry for the development of dental materials and as antibacterial, antivirals, anti-protozoals, anti-arthropods and anticancerous agents. Apart from silver, noble metal nanoparticles like gold and platinum and other nanoparticles copper, oxides of different metals, etc. have been also the materials of choice for many scientists for their biological applications. The book will be of interest to chemists, microbiologists, biotechnologist, food technologists, nanotechnologists, pharmacologists, clinicians and those interested in nature cure. Students will find this book useful and reader friendly.

Epstein-Barr virus (EBV) is a human gamma herpes virus that remains one of the most successful viral parasites known to man. It is the etiological agent of infectious mononucleosis and is the major biological cofactor contributing to a number of human cancers including B-cell neoplasms (e.g. Burkitt's lymphoma, Hodgkin's disease and immunoblastic lymphomas), certain forms of T-cell lymphoma, and some epithelial tumors (e.g. nasopharyngeal carcinomas and gastric carcinomas). The virus has the unique ability to persist in the infected, apparently healthy host for life. Understanding the molecular interaction between EBV and its human host, the ability of the virus to modulate the host immune system, its ability to hide in B-memory cells and factors that trigger viral reactivation are fundamental to understanding the cellular and molecular pathogenesis of the virus. This is critical for the development of strategies for the prevention and control of infection and disease. In this book, world renowned EBV experts provide a critical and comprehensive review of every aspect of this important virus. By integrating genetic, immunologic, and cell biologic approaches to elucidate pathogenesis, penetrating new insights into the molecular and cellular interaction between EBV and its human host have emerged. Topics covered include: discovery, history and seroepidemiology, EBV and the immune response, EBV genetics, EBV infection and persistence, latency, lytic proteins and reactivation control, vaccine approaches, animal models, and the future of EBV studies. This is essential reading for all EBV virologists as well as clinical and research scientists working on oncogenic viruses.
