The aim of this book is to show how supramolecular complexity of cell organization can dramatically alter the functions of individual macromolecules within a cell. The emergence of new functions which appear as a consequence of supramolecular complexity, is explained in terms of physical chemistry.
The book is interdisciplinary, at the border between cell biochemistry, physics and physical chemistry. This interdisciplinarity does not result in the use of physical techniques but from the use of physical concepts to study biological problems.
In the domain of complexity studies, most works are purely theoretical or based on computer simulation. The present book is partly theoretical, partly experimental and theory is always based on experimental results. Moreover, the book encompasses in a unified manner the dynamic aspects of many different biological fields ranging from dynamics to pattern emergence in a young embryo.
The volume puts emphasis on dynamic physical studies of biological events. It also develops, in a unified perspective, this new interdisciplinary approach of various important problems of cell biology and chemistry, ranging from enzyme dynamics to pattern formation during embryo development, thus paving the way to what may become a central issue of future biology.

This book sheds new light on the current state of knowledge concerning chromatin organization. Particular emphasis is given to the new imaging potential offered by super-resolution microscopy, which allows DNA imaging with a very high labeling density. From the early work on chromosomes by Walther Flemming in the nineteenth century to recent advances in genomics, the history of chromatin research now spans more than a century. The various milestones, such as the discovery of the double helix structure, the sequencing of the human genome, and the recent description of the genome in 3D space, show that understanding chromatin and chromosome function requires a clear understanding of its structure. Presenting cutting-edge data from super-resolution single molecule microscopy, the book demonstrates that chromatin manifests several levels of folding, from nucleosomes to chromosomes. Chromatin domains emerge as a new fundamental building block of chromatin architecture, with functions possibly related to gene regulation. A detailed description of chromatin folding in the pachytene stage of meiosis serves as a model for exploring this functionality, showing the apparent interplay between structure, function, and epigenetic regulation. Lastly, the book discusses possible new avenues of innovation to describe chromatin's organization and functions. Gathering essential insights on chromatin architecture, the book offers students an introduction to microscopy and its application to chromatin organization, while also providing advanced readers with new ideas for future research.

Leading researchers are specially invited to provide a complete understanding of the key topics in these archetypal multidisciplinary fields. In a form immediately useful to scientists, this periodical aims to filter, highlight and review the latest developments in these rapidly advancing fields.

The papers assembled in this volume were originally presented at the joint meeting of the Phytochemical Society of North America and the Mid-Atlantic Plant Molecular Biology Society, in August 2000. The symposium from which these chapters were prepared was entitled ""Regulation of Phytochemicals by Molecular Techniques"" and was organised by James Saunders and Ben Matthews. This joint meeting was timely because of recent landmark advances in molecular biology and genomics as well as the renewed interest in phytochemistry as a rich source of nutraceuticals, drugs, and alternatives to synthetic agriculture pesticides. Progress in genome sequencing in plants such as Arabidopsis and rice has been remarkable, as have expressed sequence tag (EST) projects in other plants, including maize and soybean. Recently, private and public sector participants of the Human Genome Project announced that a rough draft of the human genome has been constructed. These advances directly influence phytochemical investigations by providing both insight and tools for exploring and manipulating genomes.
The chapters cover a wide range of applications from molecular biology to phytochemistry, and from basic studies on promoters and gene expression to pathway regulation and engineering with transformed plants. A number of noteworthy aspects emerge from this volume: applications of molecular biology to phytochemical practical problems are succeeding; newly emerging molecular tools promise to open new doors to discovery; and remarkable progress has already occurred in phytochemical pathway engineering.

Authoritative and practical, Noncanonical Amino Acids: Methods and Protocols aims to provide readers with techniques that enable them to design new experiments and create new areas of research.

Nature, by dint of its constitution, harbors many unassuming mysteries broadly manifested by its constituent cohorts. If physics is the pivot that holds nature and chemistry provides reasons for its existence, then the rest is just manifestation. Nanoscience and technology harbor the congruence of these two core subjects, whereby many phenomenon may be studied in the same perspective. That nature operates at nanoscale-obeying the principles of thermodynamics and supramolecular chemistry-is a well understood fact manifested in a variety of life processes: bones are restored after a fracture; clots potentially leading to cerebral strokes can be dissolved. The regeneration of new structures in our system follows a bottom-up approach. Be it a microbe (benign or pathogenic), plant (lower or higher), plant parts/organs, food beneficiaries, animal (lower), higher animal processing wastes, these all are found to deliver nanomaterials under amenable processing conditions. Identically, the molecules also seem to obey the thermodynamic principles once they get dissociated/ionized and the energy captured in the form of bonding helps in the synthesis of a myriad of nanomaterials. This edited volume explores the various green sources of nanomaterial synthesis and evaluates their industrial and biomedical applications with a scope of scaling up. It provides useful information to researchers involved in the green synthesis of nanomaterials in fields ranging from medicine to integrated agricultural management.

Ions, their transport across membranes, and their flow through specialized ion channels are central to the understanding of brain function, normal and pathological. The first part of this book deals with the regulation of ions in brain extra- and intracellular fluids. Regulation is effected by the blood-brain barrier, and by membrane ion pumps and other transport mechanisms of neurons and glial cells. Normally adjusted for optimal neural function, ion levels can change and alter the excitability of neurons and influence synaptic transmission in healthy and diseased brains. After an introduction to the electrophysiology of epilepsy, and a description of experimental seizure "models," the second part discusses the roles of the faulty regulation of ions and of the diseases of ion channels in generating epileptic seizures. The mechanisms of action of various anticonvulsant drugs are also considered. The third part is devoted to the phenomenon of spreading depression and its likely role in human diseases. The final chapters of the book deal with the role of ions in the devastation caused by lack of oxygen and by insufficient blood flow to brain tissue, and the reasons for the exceptional vulnerability of certain classes of central neurons in hypoxia and stroke. The book will be of interest to neuroscientists, neurobiologists, neurophysiologists, neurologists, neurosurgeons, and to their students and trainees.

Multidisciplinary resource for graduate studies and the biotechnology industry

Knowledge of the genetic basis of biological functioning continues to grow at an astronomical rate, as do the challenges and opportunities of applying this information to the production of therapeutic compounds, specialty biochemicals, functional food ingredients, environmentally friendly biocatalysts, and new bioproducts from renewable resources. While genetic engineering of living organisms transforms the science of genomics into treatments for cancer, diabetes, and heart disease, or products for industry and agriculture, the science and technology of bioseparations are the keys to delivering these products in a purified form suitable for use by people.

The methods, theory, and materials that reduce the science of bioseparations to practice, whether in the laboratory or the plant, are the subjects of Bioseparations Engineering. Examples address purification of biomolecules ranging from recombinant proteins to gene therapy products, with footnotes detailing economics of the products. Mechanistic analysis and engineering design methods are given for:

• Isocratic and gradient chromatography
• Sedimentation, centrifugation, and filtration
• Membrane systems
• Precipitation and crystallization

Topics addressed within this framework are: stationary phase selection; separations development; modeling of ion exchange, size exclusion, reversed phase, hydrophobic interaction, and affinity chromatography; the impact of regulatory issues on chromatography process design; organization of separation strategies into logical sequences of purification steps; and bridges between molecular biology, combinatorial methods, and separations science.

A result of teaching and developing the subject matter over ten years, Bioseparations Engineering is an ideal text for graduate students, as well as a timely desk book for process engineers, process scientists, researchers, and research associates in the pharmaceutical, food, and life sciences industries.

Medicinal Chemistry of Anticancer Drugs, Second Edition, provides an updated treatment from the point of view of medicinal chemistry and drug design, focusing on the mechanism of action of antitumor drugs from the molecular level, and on the relationship between chemical structure and chemical and biochemical reactivity of antitumor agents. Antitumor chemotherapy is a very active field of research, and a huge amount of information on the topic is generated every year. Cytotoxic chemotherapy is gradually being supplemented by a new generation of drugs that recognize specific targets on the surface or inside cancer cells, and resistance to antitumor drugs continues to be investigated. While these therapies are in their infancy, they hold promise of more effective therapies with fewer side effects. Although many books are available that deal with clinical aspects of cancer chemotherapy, this book provides a sorely needed update from the point of view of medicinal chemistry and drug design.

Although contributing to the nutritional quality of the foods we consume, proteins also act as integral components by virtue of their diverse functional properties. The expression of these functional properties during the preparation, processing and storage of foods is largely dictated by changes to the structure or structure-related properties of the proteins involved. This work describes the nature of structure-function relationships so that the use of food protein sources can be optimized. The first section uses food systems as examples to demonstrate the intricate nature of the structure-function relationship. Later chapters discuss the techniques which are used to examine structural parameters or establish relationships between protein structure and function. This guide should prove useful for food chemists, scientists and technologists, and can serve as a reference for students of this field.
