Recent advances in molecular and biophysical techniques, particularly fluorescence and live cell imaging, are revolutionizing the study of cell motility. New bioprobes not only reveal simple intracellular localization, but also contain details of post-translational modifications, conformational state and protein-protein interactions. Coupling these insights with complementary advances in genetic and biochemical methods is enabling scientists to understand the processes involved in cell motility – from molecular motors to cell movements in vivo in a range of organisms and cell types. This book features landmark essays that provide an up to date and fascinating account of current research and concepts in cell motility.These cover the roles of molecular motors that drive movement and their interactions with the cytoskeleton as well as membrane dynamics that allow cells to change shape and to move. Cell motility plays a key role in development – there are chapters on the genetics of cell migration, the regulation of contact repulsion in growth cones, and the progression from cell migration to cell-cell adhesion. Cell motility is directional – experts describe the molecules that regulate chemotaxis, allowing cells to migrate along pathways specified by chemical gradients. Finally, cell motility can be perturbed by mutation–metastasis occurs when cells lose their normal intercellular interactions and invade other tissue types. All these processes are regulated by signals from the environment, including other tissues in the body, and the various molecules that transmit and transduce these signals are discussed. This book is a 'must read' for cell biologists working in a variety of fields, from development to wound healing, at all levels – post-doctoral fellows, post-graduate students and lab technicians. It is also stimulating reading for molecular and developmental biologists, biophysicists and biochemists.
Retinal dystrophies are the major causes of incurable blindness in the Western world. Our insight into their aetiology has improved remarkably over the past decade and a number of key genes have been identified. Together with a more detailed understanding of disease processes, this knowledge is stimulating new approaches to therapeutic strategies involving gene therapy, growth factors and retinal cell transplantation. Molecular genetic studies have provided detailed information on the pathogenesis of retinal dystrophies. An important proof of principle that gene therapy holds great promise for the treatment of these conditions was demonstrated in the rds mouse: introduction of a functional copy of the peripherin gene subretinally resulted in complete rescue of rod outer segment structure. Novel approaches are being developed based on the manipulation of biochemical pathways that previously were not considered relevant to these diseases. For example, renewed interest in retinal dystrophy pathogenesis led to the successful use of high dose vitamin A treatment in Sorsby fundus dystrophy. This important new book covers all aspects of retinal dystrophies from the molecular and developmental biology of these disorders to possible therapeutic approaches, with special reference to gene therapy. Specific chapters deal with the molecular genetics of gene therapies, clinical genetic studies, molecular and cellular mechanisms of the development of the disease, functional genomics of retinal diseases, animal models of retinal dystrophies, and finally with studies on gene therapeutic approaches to correcting the disorder. With contributions by many of the leading researchers worldwide, this book is likely to be an important milestone in this rapidly developing field.
Understanding stem cells at the molecular level is essential to understanding their behaviour in a physiological context. This volume in our acclaimed Novartis Foundation series features animated discussion from the world’s experts in this topic on the important ethical issues that are raised by research on stem cells. They review the various regulatory regimes, which apply in different countries – a key factor in determining where future stem cell research is carried out. Potential clinical applications covered in the book include the production of cardiomyocytes to replace damaged heart tissue, the production of insulin-producing cells for patients with diabetes, and the generation of neurons for the treatment of patients with Parkinson’s disease or spinal cord injury. Particular attention is paid to the factors that maintain stem cells in a pluripotent state or which drive them to create differentiated and lineage-committed cells in vitro and in vivo. Nuclear reprogramming, the process by which a nucleus acquires developmental potential, is covered here as well. It is relevant to stem cell research generally, and also to research on the cloning of animals by nuclear transfer. This book is an essential purchase for all those engaged in stem cell research, whether in the laboratory, the clinic or the regulatory authorities.

Navigate the complexities of biochemical thermodynamics with Mathematica(r) Chemical reactions are studied under the constraints of constant temperature and constant pressure; biochemical reactions are studied under the additional constraints of pH and, perhaps, pMg or free concentrations of other metal ions. As more intensive variables are specified, more thermodynamic properties of a system are defined, and the equations that represent thermodynamic properties as a function of independent variables become more complicated. This sequel to Robert Alberty's popular Thermodynamics of Biochemical Reactions describes how researchers will find Mathematica(r) a simple and elegant tool, which makes it possible to perform complex calculations that would previously have been impractical. Biochemical Thermodynamics: Applications of Mathematica(r) provides a comprehensive and rigorous treatment of biochemical thermodynamics using Mathematica(r) to practically resolve thermodynamic issues. Topics covered include: * Thermodynamics of the dissociation of weak acids * Apparent equilibrium constants * Biochemical reactions at specified temperatures and various pHs * Uses of matrices in biochemical thermodynamics * Oxidoreductase, transferase, hydrolase, and lyase reactions * Reactions at 298.15K * Thermodynamics of the binding of ligands by proteins * Calorimetry of biochemical reactions Because Mathematica(r) allows the intermingling of text and calculations, this book has been written in Mathematica(r) and includes a CD-ROM containing the entire book along with macros that help scientists and engineers solve their particular problems.

Heart failure is the main cause of death and disability in the industrialized world. There is a major need for novel therapeutics for prevention and reversal of cardiac pathology associated with heart failure and cardiac enlargement. Over recent years, dramatic progress has been made in unravelling the cellular circuitry involved in cardiac failure, as well as in normal cardiac growth, development and apoptosis. This work has revealed new and unexpected therapeutic targets in the heart. In addition, advances in understanding the role of stem cells in cardiac physiology have suggested strategies for cardiac repair and regeneration once thought impossible. This book describes the work of leading investigators studying the basic mechanisms of cardiac growth, function and dysfunction. There are also exciting contributions from researchers developing novel therapeutic strategies for cardiac disease. The unique feature is the discussions amongst the contributors, which always return to the same basic problem: how can new data from biological studies be used to design novel therapies for the treatment of cardiac dysfunction following myocardial infarction, hypertension and other disorders? With its strong emphasis on translational research, this book will appeal to both scientists and clinicians interested in diminishing the impact of the current epidemic of cardiac diseases.
Over the last decade, high-sensitivity calorimetry has developed from a specialist method used mainly by dedicated experts to a major, commercially available tool in the arsenal directed at understanding molecular interactions and stability. Calorimeters have now become commonplace in bioscience laboratories. As a result, the number of those proficient in experimentation in this field has risen dramatically, as has the range of experiments to which these methods have been applied. Applications extend from studies in small molecule and solvent biophysics, through drug screening to whole cell assays. The technology has developed to include higher levels of sensitivity (and hence smaller sample size requirements) and a drive towards high-throughput technology, creating a very large user base in both academia and the pharmaceutical industry. This book is a fully revised and updated edition of the successful Biocalorimetry: Applications of Calorimetry in the Biological Sciences, published in 1998. Since then, there have been many advances in the instrumentation as well as in its applications and methodology. There are general chapters highlighting the usage of the isothermal titration calorimeter and the differential scanning calorimeter, more advanced chapters on specific applications and tutorials that cover the idiosyncrasies of experimental methods and data analysis. The book draws these together to create the definitive biological calorimetric text book. This book both explains the background to the method and describes novel, high-impact applications. It features works of interest to the experienced calorimetrist and the enthusiastic dilettante. The book should be of interest to all working in the field of biocalorimetry, from graduate students to researchers in academia and in industry.
Rice is the most important food crop for half the world's population. Over the last three decades, the imporvement in human nutrition and health in Asia has largely been attributable to a relatively stable and affordable rice supply. The challenge to produce enough rice for the future, however, remains daunting, as the current rate of population growth outpaces that of increases in rice production. Science has a central role to play in raising rice productivity and this book highlights areas of plant science that are particularly relevant to solving the major constraints on rice production. Examining molecular, genetic and cellular techniques, it considers recent advances in four research approaches for increasing yields and improving the nutritional quality of rice. Plant genomics: knowing the identity and location of each gene in the rice genome is of immense value in all aspects of rice science and cultivar improvement. Molecular biological approaches to increase yield: to produce more biomass by increasing photosynthetic rate and duration, and by improving grain filling. Enhancing tolerance to biotic and abiotic stresses: with new DNA array technologies, it is now possible to assess global genomic response to stresses. Understanding the relationships among stress pathways may create new opportunities for gene manipulation to enhance tolerance to multiple biotic and abiotic stresses. Improving nutritional quality in the grain: knowledge of the biosynthesis of micronutrients in plants permits genetic engineering of metabolic pathways to enhance the availability of micronutrients.
