Investigation of the mechanisms of cellular response to different mechanical stimuli, as well as mechano-electrical feedback (MEF) in the intact heart is one of the main topics in fundamental and clinical cardiology. The present volume of "Mechanosensitivity in Cells and Tissues: Mechanosensitivity of the Heart" c- bines excellent reviews written by worldwide leaders in this ?eld. The 3rd volume is a great addition to this excellent series of books edited by Andre Kamkin and Irina Kiseleva. This volume successfully combines reviews, aimed at academic, physiology and clinical cardiology communities, devoted to mechanosensitivity of the normal and diseased heart at the ion channel, cell, tissue and organ levels. Kamkin and Kiseleva have made signi?cant contributions to the investigation of mechanosentive ion channels in cardiomyocytes and ?broblasts. Their ba- ground, in addition to extensive collaborations helped them to ?nd and consolidate valuable research ?ndings from prominent specialists in the ?eld of cardiac mechanosensitivity. In the last decade, interest in the role of MEF in the heart has increased sign- cantly. MEF within cardiac tissue is a complex phenomenon in which electroph- iological changes are triggered by myocardial stretch. This phenomenon has been studiedintheclinicalcommunityforoveracenturyandmayhavebothpro-rhythmic and arrhythmogenic consequences. While signi?cant advances have been made in understanding of the effects of mechanical forces on cardiac cells, many questions remain regarding the mechanisms whereby mechanical forces are transduced into changes which alter the behavior of various cardiac cells.

In situ hybridization has developed as a means of localizing specific DNA and RNA sequences within tissues. The great strength of this approach is the ability to relate the distribution of specific nucleic acids with cell structures and the protein products of the target gene by means of immunohistochemistry. Complementary DNA, RNA or oligonucleotide probes, suitably labelled, are hybridized to specific DNA or RNA targets within tissues. The spatial information thus obtained has contributed greatly to our understanding of such diverse areas of research as gene mapping, viral infection, cytogenetics, protein synthesis, prenatal diagnosis and tissue grafting. This book is not intended as another recipe book, although it does describe theoretical and practical aspects of the technology. Rather, the authors critically describe the contribution made by in situ hybridization to specific areas of medical research.

Abiotic stress drastically limits agricultural crop productivity worldwide. Climate change threatens the sustainable agriculture with its rapid and unpredictable effects, making it difficult for agriculturists and farmers to respond to the challenges cropping up from environmental stresses.In light of population growth and climate changes, investment in agriculture is the only way to avert wide scale food shortages. This challenge comes at a time when plant sciences are witnessing remarkable progress in understanding the fundamental processes of plant growth and development. Plant researchershave identifiedgenes controlling different aspects of plant growth and development, but many challenges still exist in creating an apt infrastructure, access to bioinformatics and good crop results. "Improvement of Crops in the Era of Climatic Changes, Volume2"focuses on many existing opportunities that can be applied methodically through conventional breeding, without touching upon the latest discoveries such as the power of genomics to applied breeding in plant biology.

Written by a diversefaction of internationally famedscholars, this volume adds new horizons in the field of crop improvement, genetic engineering and abiotic stress tolerance. Comprehensive and lavishly illustrated, "Improvement of Crops in the Era of Climatic Changes, Volume2"is a state-of-the-art guide to recent developmentsvis-a-visvarious aspects of plant responses in molecular and biochemical ways to create strong yields and overall crop improvement."

The current explosive progress in molecular biological research can be definitively traced to the development of molecular cloning technology. The ability to insert specific gene sequences into cloning vectors and their subse quent expansion is the cornerstone of modem molecular biology. A direct practical outcome of molecular cloning technology is its application to ex press specific recombinant genes. Currently, recombinant gene products are used in a wide spectrum of applications, including gene therapy, production of bioactive pharmaceuticals, synthesis of novel biopolymers, in agriculture and animal husbandry, and so on. A fundamental requirement for successful recombinant gene expression is the design of the cloning vector and the choice of the host organism for expression. Recombinant Gene Expression Protocols grows out of the need for a laboratory manual that provides the reader the background and rationale, as well as the practical protocols for the preparation of "expression constructs" and their introduction into appropriate host cells and/or organisms. The chap ters in this book are grouped by their expression hosts, including E. coli, yeast, mammalian cells, nonmammalian eukaryotes such as plants, Xenopus, and insects, as well as in transgenic organisms. In-depth information is presented on the important characteristics of expression cloning vectors and the various methods for efficiently introducing expression constructs into target cells and/ or organisms. Throughout Recombinant Gene Expression Protocols, the authors have consistently striven for a balanced presentation of both background informa tion and actual laboratory details.

Since the initial establishment of Robert Koch's postulates in the nineteenth century, microbial protein toxins have been recognized as a major factor of bacterial and fungal virulence. An increasing number of proteins produced and secreted by various bacteria, yeasts and plants are extremely toxic and most of them developed remarkably "intelligent" strategies to enter, to penetrate and to finally kill a eukaryotic target cell by modifying or blocking essential cellular components.

This book describes the strategies employed by protein toxins to render their pro- and eukaryotic producers a selective growth advantage over competitors. In providing an up-to-date overview on the mode of protein toxin actions, it accommodates biomedically and biologically relevant toxin model systems. As a result, it significantly broadens our perspective on biochemical architecture and molecular ploy behind the lethal principles of pro- and eukaryotic toxins.

The rapidly developing field of nanomaterials has expanded in many commercial areas. More recent studies have begun to provide a foundation for understanding how nanomaterials influence cells and how they also can serve as methodological tools for studies in medicine and cell biology, including research into stem cells. Recent investigations have shown affects of nanomaterials on specific subcellular structures, such as the actin-based brush border network in cells with an increasing emphasis on the barrier function of epithelial tissues. While other studies have shown involvement of nanoparticles in specific cytoplasmic signal transduction events such as the rise in intracellular free calcium, a signaling event known to regulate many changes in cell architecture and function. In parallel, nanomaterials are increasingly used in medicine for drug delivery, treatment of cancer and an increasing number of new applications. This book investigates these areas and also includes new methods for assessment in cell biology and medicine.

This thoughtful and provocative book provides a concise, up-to-date presentation of how current and projected future phosphorus scarcity will affect legume growth and their symbiotic nitrogen-fixing capabilities. It is a timely examination of the physiological and molecular responses of nodules to phosphorous deficiency in attempt to identify common principles. Students and researchers in the many disciplines related to crop productivity will find this title an exciting contribution in the area of plant stress physiology. The knowledge in this volume can also aid plant breeders, particularly through new methods of genetic engineering, in developing unique and adaptive cultivars with higher symbiotic efficiency. The awareness of the rapidly rising world population must translate into a parallel increase in agricultural production in order to sustain the growing population both now and in the future. Hence, the demand for food crops to produce proteins and vegetable oil for human consumption is going to increase considerably during the coming years. The essential role of legumes in agriculture is well-recognized, given the abundant levels of proteins and oils found in plants along with their enormous contribution to the sustainability of agricultural systems and human health. The capacity of legumes to fix nitrogen (N2) in partnership with rhizobia provides an input-saving and resource-conserving alternative, thereby reducing the need for chemical fertilizers while enhancing overall crop productivity. The use of N2-fixing legumes to produce plant proteins results in a substantial decrease in the consumption of fossil fuels and therefore also in the agricultural effects to global warming. However, a major constraint to legume production is low soil phosphorus (P) availability, considering that an overwhelming majority of the world's soils are classified as P-deficient. Low-P availability is especially problematic for legumes, since legume nodules responsible for N2 fixation have a high P requirement. Therefore, this book explains how nodule N2 fixation responds to low P availability, which is crucial for improving legume production and maintaining agricultural sustainability in the context of the global P crisis.

''Interesting with many useful ideas and references. It covers a broad range and it is a good introduction to this field.'' ---Analyst

Transposable elements are short lengths of DNA with the capacity to move between different points within a genome. This process can affect the function of genes at or near the insertion site. The present book gives an overview of the impact of transposable elements on plant genomes and explains how to recognize and study transposable elements, e.g. by using state-of-the-art strategies like "new generation sequencing." Moreover, the impact of transposable elements on plant genome structure and function is reviewed in detail, and also illustrated in examples and case studies. The book is intended both for readers familiar with the field and for newcomers. With large-scale sequencing becoming increasingly available, more and more people will come across transposable element sequences in their data, and this volume will hopefully help to convince them that they are not just "junk DNA."

The receptor-associated JAK protein kinases and their substrates, the STAT transcriptional activators, transmit signals following cytokine and growth factor binding to receptors expressed on the cell surface, to result in specific transcriptional and cellular responses. Over the last two decades, the field has progressed from identification of the individual components through to an understanding of the activation and deactivation mechanisms, and the complex structural detail of the proteins involved. We now know that these pathways are important in many biological processes, including growth and development, hematopoiesis, and the innate and adaptive immune response. JAK-STAT Signalling: Methods and Protocols provides detailed methodologies for examining many aspects of the pathway. Divided into four sections, topics include JAK and STAT specific approaches, the negative regulators of the pathway (SOCS proteins), and the production and crystallization of JAK and STAT proteins, among others. Written in the successful Methods in Molecular Biology (TM) 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 easily accessible, JAK-STAT Signalling: Methods and Protocols will be of use not only to those working in the area but also to new investigators who are led to delve into the complexities of JAK and STAT responses.

This book is the study of all codes of life with the standard methods of science. The genetic code and the codes of culture have been known for a long time and represent the historical foundation of this book. What is really new in this field is the study of all codes that came after the genetic code and before the codes of culture. The existence of these organic codes, however, is not only a major experimental fact. It is one of those facts that have extraordinary theoretical implications. The first is that most events of macroevolution were associated with the origin of new organic codes, and this gives us a completely new reconstruction of the history of life. The second implication is that codes involve meaning and we need therefore to introduce in biology not only the concept of information but also the concept of biological meaning. The third theoretical implication comes from the fact that the organic codes have been highly conserved in evolution, which means that they are the greatest invariants of life. The study of the organic codes, in short, is bringing to light new mechanisms that have operated in the history of life and new fundamental concepts in biology.

he biological sciences are dominated by the idea that cells are the functionally autonomous, physically separated, discrete units of life. TThis concept was propounded in the 19th century by discoveries of the cellular structuring of both plants and animals. Moreover, the ap parent autonomy of unicellular eukaryotes, as well as the cellular basis of the mammalian brain (an organ whose anatomy for a long while defied attempts to validate the idea of the cellular nature of its neurons), seemed to provide the final conclusive evidence for the completeness of *cell theory', a theory which has persisted in an almost dogmatic form up to the present day. However, it is very obvious that there are numerous observations which indicate that it is not the cells which serve as the basic units of biological life but that this property falls to some other, subcellular assemblage. To deal with this intricate problem concerning the fundamental unit of living matter, we proposed the so-called Cell Body concept which, in fact, devel ops an exceedingly original idea proposed by Julius Sachs at the end of the 19th century. In the case of eukaryotic cells, DNA-enriched nuclei are intimately associated with a microtubular cytoskeleton. In this configuration-as a Cell Body-these two items comprise the fundamental functional and struc tural unit of eukaryotic living matter. The Cell Body seems to be inherent to all cells in all organisms.

Nanoscale structures and materials have been explored in many biological applications because of their novel and impressive physical and chemical properties. Such properties allow remarkable opportunities to study and interact with complex biological processes. This book analyses the state of the art of piezoelectric nanomaterials and introduces their applications in the biomedical field. Despite their impressive potentials, piezoelectric materials have not yet received significant attention for bio-applications. This book shows that the exploitation of piezoelectric nanoparticles in nanomedicine is possible and realistic, and their impressive physical properties can be useful for several applications, ranging from sensors and transducers for the detection of biomolecules to sensible substrates for tissue engineering or cell stimulation. The book also focuses on the preparation, characterization and bio-applications of piezoelectric nanoparticles.

Bidirectional traffic of macromolecules across the nuclear envelope is an active and essential transport process in all eukaryotic cells. Work on various model systems has led to a tremendous increase in our understanding of nuclear transport in recent years.This volume summarizes our current knowledge of protein and RNA transport into and out of the nucleus. It contains nine up-to-date reviews which cover various aspects of nucleocytoplasmic transport, including the structure and function of the nuclear pore complex, the role of soluble transport factors in protein and RNA transport, and the regulation of protein transport through the nuclear pore.

This book focuses on the modeling and mathematical analysis of stochastic dynamical systems along with their simulations. The collected chapters will review fundamental and current topics and approaches to dynamical systems in cellular biology. This text aims to develop improved mathematical and computational methods with which to study biological processes. At the scale of a single cell, stochasticity becomes important due to low copy numbers of biological molecules, such as mRNA and proteins that take part in biochemical reactions driving cellular processes. When trying to describe such biological processes, the traditional deterministic models are often inadequate, precisely because of these low copy numbers. This book presents stochastic models, which are necessary to account for small particle numbers and extrinsic noise sources. The complexity of these models depend upon whether the biochemical reactions are diffusion-limited or reaction-limited. In the former case, one needs to adopt the framework of stochastic reaction-diffusion models, while in the latter, one can describe the processes by adopting the framework of Markov jump processes and stochastic differential equations. Stochastic Processes, Multiscale Modeling, and Numerical Methods for Computational Cellular Biology will appeal to graduate students and researchers in the fields of applied mathematics, biophysics, and cellular biology.

The "cancer stem cell" hypothesis postulates that cancer arises from a subpopulation of tumor-initiating cells or cancer stem cells (CSCs). While the idea of cancer stem cells has been around for more than a hundred years, evidence from the fields of hematology and cancer biology has now demonstrated the critical role of stem cells in hematological malignancies and suggested that these same mechanisms are also central to the initiation, progression, and treatment of solid cancers. Clinical and experimental studies have shown that CSCs exhibit many classical properties of normal stem cells, including a high self-renewal capacity and the ability to generate heterogeneous lineages; the requirement for a specific "niche"/microenvironment to grow; and an increased capacity for self-protection against harsh environments, toxins, and drugs. Cancer Stem Cells in Solid Tumors represents a detailed overview of cancer stem cells and their role in solid cancers. Comprised of 24 chapters, this volume will provide readers with a comprehensive understanding of this important and evolving field. Topics covered include: Introduction of the CSC hypothesis Historical perspectives and the contributing lessons from leukemia Current knowledge regarding the identification and role of CSCs in various forms of solid cancer including breast, brain, colorectal, pancreatic, prostate, melanoma, lung, ovarian, hepatocellular, and head and neck cancer Molecular pathways involved in driving CSC function, with a particular focus on the novel convergence of embryonic and tumorigenic signaling pathways In vitro and in vivo assays, model systems, and imaging modalities for studying CSCs The clinical importance of CSCs for cancer management and treatment, including important implications for prognosis, prediction, and treatment resistance Consideration of the controversy surrounding the CSC hypothesis and important unanswered questions in this field This collective work was written by a group of prominent international experts in cancer biology, oncology, and/or stem cell biology. It will serve as a valuable resource for established researchers, professors, health care professionals, and students in the medical and scientific community who are investigating stem cells and/or oncology.

Sequencing projects have revealed the presence of at least several hundred receptor kinases in a typical plant genome. Receptor kinases are therefore the largest family of primary signal transducers in plants, and their abundance suggests an immense signaling network that we have only just begun to uncover. Recent research findings indicate that individual receptor kinases fulfill important roles in growth and development, in the recognition of pathogens and symbionts or, in a few examples, in both growth and defense. This volume will focus on the roles of receptor kinases, their signaling pathways, and the ways in which these important signaling proteins are regulated.
