Animal cloning has developed quickly since the birth of Dolly the sheep. Yet many of the first questions to be raised still need to be answered. What do Dolly and her fellow mouse, cow, pig, goat and monkey clones mean for science? And for society? Why do so many people respond so fearfully to cloning? What are the ethical issues raised by cloning animals, and in the future, humans? How are the makers of public policy coping with the stunning fact that an entire animal can be reconstructed from a single adult cell? And that humans might well be next? The Cloning Source Book addresses all of these questions in a way that is unique in the cloning literature, by grounding what is effectively an interdisciplinary conversation in solid science. In the first section of the book, the key scientists responsible for the early and crucial developments in cloning speak to us directly, and other scientists evaluate and comment on these developments. The second section explores the context of cloning and includes sociological, mythological, and historical perspectives on science, ethics, and policy. The authors also examine the media’s treatment of the Dolly story and its aftermath, both in the United States and in Britain. The third section, on ethics, contains a broad range of papers written by some of the major commentators in the field. The fourth section addresses legal and policy issues. It features individual and collective contributions by those who have actually shaped public policy on reproductive cloning, therapeutic cloning, and similarly contentious bioethical issues in the United States, Britain, and the European Union. Animal cloning continues for agricultural and medicinal purposes, the latter in combination with transgenics. Human cloning for therapeutic purposes has recently been made legal in Britain. The goal is to produce an early embryo and then derive stem cells that are immunologically matched to the donor. Two human reproductive cloning projects have been announced, and there are almost certainly others about which we know nothing. Sooner or later a cloned human will be born. Many lessons can be learned from the cloning experience. Most importantly, there needs to be a public conversation about the permissible uses of new and morally murky technologies. Scientists, journalists, ethicists and policy makers all have roles to play, but cutting-edge science is everybody’s business. The Cloning Sourcebook provides the tools required for us to participate in shaping our own futures.

Introduction to Fluorescence Sensing
Fluorescence sensing is a rapidly developing field of research and technology. Its target is nearly the whole world of natural and synthetic compounds being detected in different media including living bodies. The application area range from control of industrial processes to environment monitoring and clinical diagnostics. Among different detection methods fluorescence techniques are distinguished by ultimate sensitivity, high temporal and spatial resolution and versatility that allows not only remote detection of different targets but their imaging within the living cells. The basic mechanism of sensing is the transmission of the signal produced by molecular interaction with the target to fluorescent molecules, nanoparticles and nanocomposites with the detection by devices based on modern electronics and optics. In this interdisciplinary field of research and development the book is primarily intended to be a guide for students and young researchers. It is also addressed to professionals involved in active research and product development serving as a reference for the recent achievements. The users of these products will find description of principles that could allow proper selection of sensors for particular needs. Making a strong link between education, research and product development, this book discusses future directions.

Mathematical Biophysics
This book presents concise descriptions and analysis of the classical and modern models used in mathematical biophysics. The authors ask the question ‘what new information can be provided by the models that cannot be obtained directly from experimental data?’ Actively developing fields such as regulatory mechanisms in cells and subcellular systems and electron transport and energy transport in membranes are addressed together with more classical topics such as metabolic processes, nerve conduction and heart activity, chemical kinetics, population dynamics, and photosynthesis. The main approach is to describe biological processes using different mathematical approaches necessary to reveal characteristic features and properties of simulated systems. With the emergence of powerful mathematics software packages such as MAPLE, Mathematica, Mathcad, and MatLab, these methodologies are now accessible to a wide audience.
Machina Carnis
Originally published in 1971, this is an account of the centuries of experiment and speculation that have led to our understanding of how muscles work. The book traces all the developments in the field since 1600 and devotes special attention to the breakthroughs made in the last century. It considers the nature of the muscle machine and its fuel, as well as the intricate regulation of energy supply under different conditions. It also examines the very varied kinds of muscle and the effects of some diseases on their structure and function. Finally it shows how the energy metabolism first elucidated for the mechanical work of muscle has been found to explain most of the other kinds of work done by cells, as in light production, secretion, ionic transport and electrical discharge. The biochemistry of muscle, carbohydrate metabolism and phosphorylations was the author’s chosen field of research for over forty years.

Evolutionary Games in Complex Topologies
There are many examples of cooperation in Nature: cells cooperate to form tissues, organs cooperate to form living organisms, and individuals cooperate to raise their offspring or to hunt. However, why cooperation emerges and survives in hostile environments, when defecting would be a much more profitable short-term strategy, is a question that still remains open. During the past few years, several explanations have been proposed, including kin and group selection, punishment and reputation mechanisms, or network reciprocity. This last one will be the center of the present study. The thesis explores the interface between the underlying structure of a given population and the outcome of the cooperative dynamics taking place on top of it, (namely, the Prisoner’s Dilemma Game). The first part of this work analyzes the case of a static system, where the pattern of connections is fixed, so it does not evolve over time. The second part develops two models for growing topologies, where the growth and the dynamics are entangled.

Green Architecture
ARCHITECTURAL STRUCTURE & DESIGN. When is a house ecological? Does the use of natural materials and solar cells on the roof make a building an example of ‘green’ architecture? Perhaps even Antoni Gaudi and Frank Lloyd Wright designed ‘greener’ buildings than most contemporary architects, whose low-energy houses scarcely differ outwardly from traditional ones.James Wines puts up the various – and often irreconcilable – concepts of environmentally-friendly architecture for discussion, making a case for an architecture that not only focuses on technological solutions, but also tries to reconcile man and nature in its formal idiom. Among the examples of contemporary ecological architecture presented are works by Emilio Ambasz, Gustav Peichl, Arthur Quarmby, Jean Nouvel, Sim Van der Ryn, Jourda and Perraudin, Log ID, James Cutler, Stanley Saitowitz, Francois Roche, Nigel Coates and Michael Sorkin.

Physiology and Physiopathology of Adipose Tissue
The scientific advances in the physiology and pathophysiology of adipose tissue over the last two decades have been considerable. Today, the cellular and molecular mechanisms of adipogenesis are well known. In addition, adipose tissue is now recognized as a real endocrine organ that produces hormones such as the leptin acting to regulate food intake and energy balance in the central nervous system, a finding that has completely revolutionized the paradigm of energy homeostasis. Other adipokines have now been described and these molecules are taking on increasing importance in physiology and pathophysiology. Moreover, numerous works have shown that in obesity, but also in cases of lipodystophy, adipose tissue was the site of a local low-grade inflammation that involves immune cells such as macrophages and certain populations of lymphocytes. This new information is an important step in the pathophysiology of both obesity and related metabolic and cardiovascular complications. Finally, it is a unique and original work focusing on adipose tissue, covering biology and pathology by investigating aspects of molecular and cellular biology, general, metabolic, genetic and genomic biochemistry.

Angiogenesis and Anti-Angiogenesis in Hematological Malignancies
It has been generally accepted that angiogenesis is involved in the pathogenesis of hematological malignancies, like acute and chronic leukemia, lymphoma, myelodysplastic syndromes, myeloproliferative neoplasms and multiple myeloma. The extent of angiogenesis in the bone marrow has been correlated with disease burden, prognosis and treatment outcome. Reciprocal positive and negative interactions between tumor cells and bone marrow stromal cells, namely hematopoietic stem cells, fibroblasts, osteoblasts/osteoclasts, endothelial cells, endothelial progenitor cells, T cells, macrophages and mast cells, mediated by an array of cytokines, receptors and adhesion molecules, modulate the angiogenic response in hematological tumors. More recently, it has been emphasized the pro-angiogenic role of the so called vascular niche, indicating a site rich in blood vessels where endothelial cells and mural cells such as pericytes and smooth muscle cells create a microenvironment that affects the behavior of several stem and progenitor cells, in hematological malignancies.

Liquid Crystalline Semiconductors
Liquid Crystals [LCs] are synthetic functional materials par excellence and are to be found in many types of LCDs; LCs self-assemble into ordered, but fluid, supramolecular structures and domains; they can be oriented in large homogeneous monodomains by electric and magnetic fields, Langmuir Blodgett techniques and also by self-orientation on suitable alignment layers; they are also anisotropic with preferred axes of light absorption, emission and charge transport with excellent semiconducting properties; they are soluble in organic solvents and can be deposited as uniform thin layers on device substrates, including plastic, by low-cost deposition processes, such as spin coating and doctor blade techniques; reactive mesogens [polymerisable LC monomers] can be photopatterned and fixed in position and orientation as insoluble polymer networks. LCs are increasingly being used as active components in electronic and photonic organic devices, such as Organic Light-Emitting Diodes [OLEDs], Organic Field Effect Transistors [OFETs], Thin Film Transistors [TFTs] and photovoltaic cells [PVs]. Such devices on plastic substrates represent a major component of the plastic electronics revolution. The self-assembling properties and supramolecular structures of liquid crystals can be made use of in order to improve the performance of such devices. The relationships between chemical structure, liquid crystalline behaviour and other physical properties, such as charge-transport, photoluminescence and electroluminescence are discussed and explained. For example, high carrier-mobility, polarised emission and enhanced output-coupling are identified as the key advantages of nematic and smectic liquid crystals for electroluminescence. The advantageous use of anisotropic polymer networks formed by the polymerisation of reactive mesogens [RMs] in devices with multilayer capability and photopatternability is described. The anisotropic transport and high carrier mobilities of columnar liquid crystals make them promising candidates for photovoltaics and transistors. The issues in the design and processing of liquid crystalline semiconductors for such devcies with improved performance are described. The photonic properties of chiral liquid crystals and their use as mirror-less lasers are also discussed.

Lectures on Quantum Mechanics
Beautifully illustrated and engagingly written, Twelve Lectures in Quantum Mechanics presents theoretical physics with a breathtaking array of examples and anecdotes. Basdevants style is clear and stimulating, in the manner of a brisk lecture that can be followed with ease and enjoyment. Here is a sample of the books style, from the opening of Chapter 1: ‘If one were to ask a passer-by to quote a great formula of physics, chances are that the answer would be E = mc2. There is no way around it: all physics is quantum, from elementary particles, to stellar physics and the Big Bang, not to mention semiconductors and solar cells.’
