This unique and authoritative book presents an up-to-date overview of the many aspects of energy balance and its relationships to disease processes resulting from excess energy consumption and storage. It provides a comprehensive treatment of important research and clinical aspects of energy metabolism and obesity. It will be a valuable resource for endocrinologists, diabetes specialists, internists and family practitioners.
It has become clear that tumors result from excessive cell proliferation and a corresponding reduction in cell death caused by the successive accumulation of mutations in key regulatory target genes over time. During the 1980s, a number of oncogenes were characterized, whereas from the 1990s to the present, the emp- sis has shifted to tumor suppressor genes (TSGs). It has become clear that oncogenes and TSGs function in the same pathways, providing positive and negative growth regulatory activities. The signaling pathways controlled by these genes involve virtually every process in cell biology, including nuclear events, cell cycle, cell death, cytoskeletal, cell membrane, angiogenesis, and cell adhesion effects. Mu- tions in tumor suppressor genes have been identified in familial cancer syndromes, and the same genes in many cases have been found to be mutationally inactivated in sporadically occurring cancers. In their normal state, TSGs control cancer development and progression, as well as contribute to the sensitivity of cancers to a variety of therapeutics. Understanding the classes of TSGs, the biochemical pa- ways they function in, and how they are regulated provides an essential lesson in cancer biology. We cannot hope to advance our current knowledge and to develop new and more effective therapies without understanding the relevant pathways and how they influence the present approaches to therapy. Moreover, it is important to be able to access not only the powerful tools now available to discover these genes, but also their links to cell biology and growth control.
Despite remarkable progress in genome science, we are still far from a clear understanding of how genomic DNA is packaged without entanglement into a nucleus, how genes are wrapped up in chromatin, how chromatin structure is faithfully inherited from mother to daughter cells, and how the differential expression of genes is enabled in a given cell type. Exploring and answering these questions constitutes one of the next frontiers in the 21st century. We are just beginning to appreciate how Multifarious DNA structures provide additional structural and functional dimensions to chromatin organization and gene expression. DNA Conformation and Transcription is the first book that compiles the fruits of the studies that have been performed to date to solve the riddle 'written' in DNA conformation ("conformation code"). This book provides a comprehensive overview of the field by covering history of the field, up-to-date topics, clarifications of present day research, and future perspective of what is still to be discovered. Thus, it serves as an invaluable source of information on the "conformation code".
The processes of aging and death remain one of the most fascinating, and mysterious, areas of biological research. Huge anomalies between species raise questions the answers to which could have fundamental implications for the field of medical science. As scientists unlock the secrets of the exceptionally long-lived little brown bat (up to 34 years), or the common budgerigar, for example, which despite having a metabolic rate 1.5 times that of a laboratory mouse, can live for up to 20 years, it has become more important than ever to be able to make a comparative analysis of the various species used in research. Dealing with every one of the mammalian species that are employed in laboratory research, this is the first book on the subject of aging that provides detailed comparative data for age-related changes in its subjects. It does so at the level of the whole animal, its organs, organelles and molecules. The comparative data, supplied in 15 chapters by leading experts, provides information on fields as disparate as telomere function and loss, the importance of the Sirtuins and Tor, the influence of hormones on lifespans, the relationship between body size and lifespan, the effects of restricted calorific intake, age-related changes in cell replication, and DNA damage and repair. Chapters are devoted to cardiac aging, comparative skeletal muscle aging, the aging of the nervous and immune systems, the comparative biology of lyosomal function and how it is affected by age, and many other key areas of research. This much-needed text will provide scientists working in a wide spectrum of fields with key data to aid them in their studies.
This volume represents the first collection of articles contributed by research leaders working on the Myb family of transcriptional regulatory proteins. In more than twenty chapters the authors discuss the range of biological processes and diverse cell types in which Myb proteins operate. Although concentrating on the three vertebrate Myb family members, homologues from lower species are also discussed because of the light they are able to shed on the evolution and function of these proteins. Individual chapters describe the involvement of Myb proteins, in particular c-Myb, in normal and diseased development and function of many tissues including haemopoietic cells, blood vessels, the gastrointestinal tract and the brain. Several chapters explore the mechanistic details of the action of Myb proteins, especially structural features, their interaction with DNA and other regulatory proteins, and the variety of genes that are regulatory targets for this group of transcription factors. This work will be of interest to those working directly in the field and also to the wider research community investigating the transcriptional regulation of development, differentiation and growth. The therapeutic potential of manipulating Myb function is also discussed making the book appealing to clinician scientists in several fields including haematology, oncology and cardiology.
For counselor Nancy Wainer Cohen, this book is the sibling to "Silent Knife: Cesarean Prevention and Vaginal Birth after Cesarean "(Bergin & Garvey, 1983) her critically-acclaimed expose on America's growing reliance on cesarean sections. "Open Season "provides fresh insights and new information on the subject, offering guidance to childbearing couples, educators, health professionals, and scholars who value the natural path of childbirth. Readers will find this book timely, informative, shocking, irreverent, and extremely readable. Cohen's intimate writing style presents a compendium of knowledge on childbirth in the fashion of a personal letter. Her aim is to lower America's alarming reliance on cesarean section, which is currently at 25 percent of all births, and to return the responsibility for childbirth to women by encouraging them to choose the kind of birthing experience they wish to have. In addition to cesarean section, Cohen discusses many other generally unnecessary interventions performed on women during pregnancy and childbirth--such as fetal monitoring and routinized hospital procedures.
Genetic susceptibility refers to how variations in a person 's genes increase or decrease his or her susceptibility to environmental factors, such as chemicals, radiation and lifestyle (diet and smoking). This volume will explore the latest findings in the area of genetic susceptibility to gastrointestinal cancers, focusing on molecular epidemiology, DNA repair, and gene-environment interactions to identify factors that affect the incidence of GI cancers. Topics will include germline susceptibility, including Mendelian patterns of inheritance and gene-environment interactions that lead to cancer etiology.
The world's population is growing at an unsustainable rate. From a baseline ?gure of one billion in 1800, global population is predicted to exceed nine billion by 2050 and 87. 8% of this growth will be localized in less developed countries. Such uneven population growth will yield a harvest of poverty, malnutrition, disease and en- ronmental degradation that will affect us all. Amongst the complex mixture of political, social, cultural and technological changes needed to address this issue, the development of improved methods of fertility regulation will be critical. The inadequacy of current contraceptive technologies is indicated by recent data s- gesting that the contraceptive needs of over 120 million couples go unmet every year. As a direct consequence of this de?cit 38% of pregnancies are unplanned and more than 50% end in an abortion, generating a total of 46 million abortions per annum particularly among teenagers. If safe, effective contraceptives were ava- able to every couple experiencing an unmet family planning need, 1. 5 million lives would be saved each year (UNFPA 2003). Progress in contraceptive technology should not only generate more effective methods of regulating fertility, but should also provide a range of methods to meet the changing needs of the world's population. Contraceptive practice was revo- tionized in 1960 in the US and 1961 in Europe by the introduction of the oral contraceptive pill by Gregory Pincus, MC Chang and colleagues, based on fun- mental hormone research conducted in Germany.
Pharmacogenomics supports personalized medicine by translating genome-based knowledge into clinical practice, offering enhanced benefit for patients and health-care systems at large. Current routine practice for diagnosing and treating patients is conducted by correlating parameters such as age, gender and weight with risks and expected treatment outcomes. In the new era of personalized medicine the healthcare provider is equipped with improved ability to prevent, diagnose, treat and predict outcomes on the basis of complex information sources, including genetic and genomic data. Targeted therapy and reliable prediction of expected outcomes offer patients access to better healthcare management, by way of identifying the therapies effective for the relevant patient group, avoiding prescription of unnecessary treatment and reducing the likelihood of developing adverse drug reactions.
This book reports the text of the lectures of the 6th International Conference on Sodium Calcium Exchange held in Lacco Ameno in the Island of Ischia in the Gulf of Naples, Italy, from October 1 to October 5, 2011. The present book uncovers the most striking new findings on NCX that emerged since the previous Conference on Sodium Calcium Exchange, such as the structural dissection of the molecular determinants of Ca2+ sensitivity of the exchanger, the epigenetic regulation of ncx1 gene, the molecular identification of the mitochondrial Sodium Calcium Exchanger, and the discovery of NCX in unexpected anatomical locations such as the female reproductive tract. The book is organized into 11 parts covering NCX structural aspects, genetic and epigenetic regulation, regulatory mechanisms, subcellular localization in mitochondria, involvement in neurodegenerative diseases and in immune regulation, and the role of the cardiovascular and endocrine systems, as well as diabetes in physiology and pathophysiology. Selected chapters of the book are also devoted to the interaction of NCKX and other ion channels and transporters with NCX, like ASICs, TRPM, and NHE.
Apoptosis is a form of cell death that occurs in a controlled manner and is generally noninflammatory in nature. Apoptosis, or programmed cell death, implies a cell death that is part of a normal physiological process of pruning of unneeded cells. However, many disease conditions utilize apoptosis for pathological ends, resulting in inappropriate cell death and tissue destruction. This book starts with an introduction that reviews the general characteristics of apoptosis, its regulation and its role in physiology and disease. Next, the book focuses on three areas as they relate to inflammatory cells and diseases. The first area consists of chapters on signals for apoptosis important to inflammatory cells, namely growth factors and arachidonic acid metabolism. The next area that the book focuses on are effects at the cellular level, on cell survival versus cell death and signals critical for cell function in both normal and disease states. These topics are covered in chapters on lymphocytes, granulocytes, chondrocytes and keratinocytes. The last area that the book focuses on are events at the level of tissue and disease, looking at the evidence for altered apoptosis and/or apoptotic processes in immune and inflammatory diseases. These topics are covered in chapters on rheumatoid arthritis, osteoarthritis, lupus, psoriasis and renal disease. Together, these chapters will provide the reader with the latest insight in the role of apoptosis in inflammatory cells and diseases.

In 1898, an Austrian microbiologist Heinrich Winterberg made a curious observation: the number of microbial cells in his samples did not match the number of colonies formed on nutrient media (Winterberg 1898). About a decade later, J. Amann qu- tified this mismatch, which turned out to be surprisingly large, with non-growing cells outnumbering the cultivable ones almost 150 times (Amann 1911). These papers signify some of the earliest steps towards the discovery of an important phenomenon known today as the Great Plate Count Anomaly (Staley and Konopka 1985). Note how early in the history of microbiology these steps were taken. Detecting the Anomaly almost certainly required the Plate. If so, then the period from 1881 to 1887, the years when Robert Koch and Petri introduced their key inventions (Koch 1881; Petri 1887), sets the earliest boundary for the discovery, which is remarkably close to the 1898 observations by H. Winterberg. Celebrating its 111th anniversary, the Great Plate Count Anomaly today is arguably the oldest unresolved microbiological phenomenon. In the years to follow, the Anomaly was repeatedly confirmed by all microb- logists who cared to compare the cell count in the inoculum to the colony count in the Petri dish (cf., Cholodny 1929; Butkevich 1932; Butkevich and Butkevich 1936). By mid-century, the remarkable difference between the two counts became a universally recognized phenomenon, acknowledged by several classics of the time (Waksman and Hotchkiss 1937; ZoBell 1946; Jannasch and Jones 1959).
This book gathers together contributions from internationally renowned authors in the field of cardiovascular systems and provides crucial insight into the importance of sex- and gender-concepts during the analysis of patient data. This innovative title is the first to offer the elements necessary to consider sex-related properties in both clinical and basic studies regarding the heart and circulation on multiscale levels (i.e. molecular, cellular, electrophysiologically, neuroendocrine, immunoregulatory, organ, allometric, and modeling). Observed differences at (ultra)cellular and organ level are quantified, with focus on clinical relevance and implications for diagnosis and patient management. Since the cardiovascular system is of vital importance for all tissues, Sex-Specific Analysis of Cardiovascular Function is an essential source of information for clinicians, biologists, and biomedical investigators. The wide spectrum of differences described in this book will also act as an eye-opener and serve as a handbook for students, teachers, scientists and practitioners.

Since the first gap junction protein (connexin) was cloned over a decade ago, more than a dozen connexin genes have been cloned. Consequently, a wealth of information on the molecular basis of gap junctional communication has been accumulated. This book pays tribute to this exciting era in the history of cell communication research by documenting the great strides made in this field as a result of the merging of biophysics and molecular biology, two of the most powerful approaches to studying the molecular basis of membrane channel behavior. Twenty-eight comprehensive chapters, authored by internationally recognized leaders in the field, discuss the biophysical, physiological, and molecular characteristics of cell-to-cell communication via gap junctions. Key aspects of molecular structure, formation, gating, conductance, and permeability of vertebrate and invertebrate gap junction channels are highlighted. In addition, a number of chapters focus on recent discoveries that implicate connexin mutations and alterations of gap junctional communication in the pathogenesis of several diseases, including the X-linked Charcot-Marie-Tooth demyelinating disease, some forms of inherited sensorineural deafness, malignant transformation, cardiac malformations and arrhythmia, eye lens cataract, and Chagas disease.
Sunao Tawara's epoch-making work on the excitation conduction system of the mammalian heart paved the way for the advancement of modern cardiology in the 20th century. Even today, more than 90 years after the publication of the German monograph "Das Reizleitungssystem des Saugetierherzen", his precise account of the conduction system from the atrioventricular node through the His-Purkinje system to the ordinary ventricular muscle fibers retains all of its original actuality.This English edition of Tawara's monograph will serve as an invaluable reference for both basic and clinical cardiological research in the years ahead.
This work presents the most advanced discoveries from translational research laboratories directly involved in identifying molecules and signalling pathways that play an instrumental role in metastasis. In contrast to other works, conventionally focused on a single type of tumour, the various chapters in this book provide a broad perspective of the similarities and discrepancies among the dissemination of several solid malignancies. Through recurrent and overlapping references to molecular mechanisms and mediators, the readers will gain knowledge of the common ground in metastasis from a single source. Finally, an introductory chapter provides a clinical perspective of the problems presented by metastatic tumours for diagnosis and treatment. The work presented here is directed to researchers in tumour biology with a developing interest in metastatic dissemination as well as medical and graduate students seeking to expand and integrate the notions acquired in basic cancer biology and oncology courses.
The polymerase chain reaction (PCR) is one of the most important molecular biological methods ever devised, with numerous applications to cli- cal molecular medicine. Since its description in 1985, PCR has undergone tremendous improvements, and many variations on the basic PCR theme have been published. With such a large volume of PCR-related literature, a clinical scientist wishing to use the technique will have a difficult task loc- ing the relevant information to implement it effectively. There is thus clearly a need for an up-to-date volume with detailed protocols to facilitate the setting up of those techniques most relevant to clinical applications. Unlike some other books on this topic, Clinical Applications of PCR includes only methods that are of direct relevance in clinical settings. The book is organized in three parts: an introductory section, a section on general methodology, and a final section with specific clinical applications. The first section covers the basic principles of PCR and is most useful to those new to molecular diagnosis. The next chapter includes useful tips for setting up a PCR laboratory. Section 2 then outlines some of the most commonly used PCR-based techniques in molecular diagnosis. Section 3 includes carefully chosen examples that represent typical applications of PCR in diverse clinical fields, encompassing hematology, oncology, genetics, and microbiology. |
