This book is a compilation of presentations at the first meeting devoted to the mo lecular and cellular biology of copper transport. When we first considered the possible program for the meeting, we felt that a forum to integrate the recent advances in molecular understanding of copper transport with the older knowledge of copper metabolism was needed. In addition we wished to have a strong emphasis on the diseases of copper includ ing the genetic diseases, Menkes and Wilson, and other possible health aspects of this met al seen from a molecular perspective. Overall we were very happy with the success of the meeting, and most participants were very enthusiastic. Unfortunately we were not able to obtain manuscripts from every contributor, but the selection in this book covers most of the topics discussed. The history of biological research into copper dates from the latter half of the last century when the presence of copper as a component of living systems was first noted, but it was not until the 1920s that the essential role of copper was first recognized. l. S. McHargue found that plants and animals needed copper for optimal growth and health and proposed that copper was needed for life (McHargue, 1925). Other groups soon confirmed these observations in plants. In animals the requirement of copper for hematopoiesis was discovered in 1928 (Hart et aI."

The subject for a volume on the fat-soluble vitamins needs no justification considering the importance of this group of nutrients and the rate of expan sion of our knowledge of its role in cell biology, genetics, and disease. The level of our understanding has clearly moved from knowing what fat soluble vitamins do to how they perform their functions. Hand in hand with a knowledge of their molecular mechanisms of action is the recognition that vitamins are used sparingly, and regeneration processes operate in certain cases to recycle vitamins from their metabolites. We have divided the volume into alphabetical sections beginning with vitamin A and the carotenoids through vitamins D, E, F, and K, and ending with coenzyme Q. The contributors are all acknowledged experts in their particular fields and have made significant contributions to published research results. All have worked assiduously to deliver the product of their labors on a restricted time scale and to provide the most up-to date information on their respective topics. We are truly grateful for their indulgence."

The NATO Advanced Research Workshop (ARW) on "Regulation of Enzymatic Systems Detoxifying Xenobiotics in Plants" intended to provide a forum to scientists from academia, industry, and govemment for discussing and critically assessing recent advances in the field of xenobiotic metabolism in plants and for identifying new directions for future research. Plants function in a chemical environment made up of nutrients and xenobiotics. Xenobiotics (foreign chemicals) are natural or synthetic compounds that can not be utilized by plants for energy-yielding metabolism. Plants may be exposed to xenobiotics either deliberately, due to their use as pesticides or accidentally, from industrial, agricultural, and other uses. Plants, like most other organisms, evolved a remarkable battery or metabolic reactions to defend themselves against the potentially toxic effects of xenobiotics. The main enzymatic reactions utilized by plants for xenobiotic detoxification include oxidation, reduction, hydrolysis and conjugation with glutathione, sugars (e.g., glucose), and amino acids. Eventually, xenobiotic conjugates are converted to insoluble bound residues or to secondary conjugates, which are deposited in the vacuole of plant cells.

This volume provides an exhaustive review of the most current knowledge of the composition, architecture and dynamics of the nuclear envelope. In contrast to other comprehensive works on cellular membranes in general, this book is the first to specifically address the nuclear envelope. Experts in the field relate the different domains of the nuclear envelope, their biogenesis, their composition, their mode of targeting to chromosomes and how they dissociate from chromosomes upon cell division. A wealth of information from several experimental systems is provided, such as dividing somatic cells, embryos and nuclear assembly assays in cell-free extracts, in a wide range of vertebrate and invertebrate organisms ranging from humans to yeast. The book also contains up-to-date reviews on the relationship between mutations in proteins of the nuclear envelope and Emery-Dreifuss muscular dystrophy. The breadth of topics covered in what may seem to be a field as narrow as the nuclear envelope makes this volume a valuable reference.

This book covers new techniques in protein NMR, from basic principles to state-of-the-art research. It covers a spectrum of topics ranging from a "toolbox" for how sequence-specific resonance assignments can be obtained using a suite of 2D and 3D NMR experiments and tips on how overlap problems can be overcome. Further topics include the novel applications of Overhauser dynamic nuclear polarization methods (DNP), assessing protein structure, and aspects of solid-state NMR of macroscopically aligned membrane proteins. This book is an ideal resource for students and researchers in the fields of biochemistry, chemistry, and pharmacology and NMR physics. Comprehensive and intuitively structured, this book examines protein NMR and new novel applications that include the latest technological advances. This book also has the features of: * A selection of various applications and cutting-edge advances, such as novel applications of Overhauser dynamic nuclear polarization methods (DNP) and a suite of 2D and 3D NMR experiments and tips on how overlap problems can be overcome * A pedagogical approach to the methodology * Engaging the reader and student with a clear, yet critical presentation of the applications

Leading academic and biomedical researchers comprehensively review the status of essential fatty acids (EFA) in nutrition, medicine, psychology, and pharmacology. Topics range from a discussion of EFA basic mechanisms to their effects on individual psychiatry and behavior, and include extensive coverage of pathology, DHA in CNS development, and phospholipid and fatty acid composition and metabolism. Comprehensive and forward-looking, Fatty Acids: Physiological and Behavioral Functions reviews and critically evaluates our current knowledge of EFA, setting the stage for oncoming wave of discovery about the biochemical and molecular functions of essential fatty acids, as well as their critical role in human physiology, immunology, and behavior.

The use oflasers has entered almost every facet of medicine and biology. Therefore, it is to be expected that the reviews contained in this vol urne will reflect this diversity. As dinical acceptance has grown with various diagnostic and therapeutic applications, so has the need for a more thorough understanding of the theoretical background for each. This is especially true where a correlation is to be made between the theoretical background and the experimental data. It is only in this way that we can attain the optimal form of any therapy. The basic coupling ofenergy into biological tissue and its conversion into heat is characterized by many parameters. One ofthe most important is pulse duration. The review by Bimgruber in Chapter 6 shows how our knowledge ofthis parameter has been extended.The need for a more basic understanding of the interaction of electromagnetic energy with various kinds of materials has led to investigations on the nature of plasmas their stability and instability, and how theyexist. Docchio reviews the factors that cause them to occur at a specific locale and then to move away from that site. The availabilityofmany types ofoptical fibers has extended our ability to deliver laser energy from various types oflasers into almost anyselected location. This is particularly useful in medicine, where less invasive ap proaches to surgery and diagnosis are always helpful. However, as Rol and his colleagues explain, the power-handling capabilities ofoptical fibers limit many applications, particularly for short-duration, high-peak-power laser pulses."

The plasma membrane is at once the window through which the cell senses the environment and the portal through which the environment influences the structure and activities of the cell. Its importance in cellular physiology can thus hardly be overestimated, since constant flow of materials between cell and environment is essential to the well-being of any biological system. The nature of the materials mov ing into the cell is also critical, since some substances are required for maintenance and growth, while others, because of their toxicity, must either be rigorously excluded or permitted to enter only after chemical alteration. Such alteration frequently permits the compounds to be sequestered in special cellular compartments having different types of membranes. This type of homogeneity, plus the fact that the wear and tear of transmembrane molecular traffic compels the system to be constantly monitored and repaired, means that the membrane system of any organism must be both structurally complex and dy namic. Membranes have been traditionally difficult to study because of their fragility and small diameter. In the last several decades, however, remarkable advances have been made because of techniques permit ting the bulk isolation of membranes from homogenized cells. From such isolated membranes have come detailed physical and chemical analyses that have given us a detailed working model of membrane. We now can make intelligent guesses about the structural and func tional interactions of membrane lipids, phospholipids, proteins, sterols and water.

Dr. Heinonen reviews and critically evaluates the scientific literature on the biological role of inorganic pyrophosphate (PPi ) published from 1940 to the end of 1999. He describes and classifies all known biochemical reactions that produce Ppi; describes and evaluates all published methods used in biological Ppi; and compiles and critically evaluates information on the concentration of PPi (with the conclusion that, contrary to common belief, PPi exists throughout the living world in rather high concentrations). Many reactions in which PPi is used as a biochemical energy source instead of ATP have been described in recent decades, especially in bacteria, protists, and plants. These reactions are evaluated from the bioenergetic and regulatory points of view. Also considered is the possible role of PPi as a source of biochemical energy in the primitive phases of life, before ATP. Data is presented on the regulatory role of PPi in living systems, such as activities of enzymes, fidelity of syntheses of macromolecules, and proliferation of cells. PPi may also regulate the formation and dissolution of bone as well as pathologic calcification of soft tissues and the formation of urinary stones. The formation of calcium pyrophosphate dihydrate crystals in the extracellular fluids of joints cause the disease called pseudogout. Biological Role of Inorganic Pyrophosphate book is a unique and invaluable source of references (about 1120) and summarized data for professionals who study or plan to study the role of PPi in living systems. Many different branches of science (biochemistry, microbiology, bioenergetics, plant physiology, parasitology, evolution, orthopedics, rheumatology) have involvement with PPi. This book sums up available knowledge in one place and will help scientists cross disciplinary boundaries.

Through a series of essays concerning human eating seen from the perspective of contemporary biology/medicine and recent research articles, the book explores the links between food and Man's cultural and physical evolution. Each chapter has an introduction summarizing the basic knowledge in the field, discusses the recent research results, and confirms or challenges the established concepts, which opens new aspects and leads to new questions. This book catalyzes discussion between scientists working on one side in food science and on the other side in biological and biomedical research.

The beginnings of human civili zation can be traced back to the time , ne- ly 12 ,000 years ago , when th e early humans gradually ch anged from a life of hunting and gathering food , to producing food. This beginning of pri- tive agriculture ensured a dependable supply of food , and fostered the living together of people in groups and the development of s o c i e ty. During th is time, plant s e e ds were recognized a s a valuable s o ur c e of food and nutrition , and began to be used for growing plants for food. Ever s i n c e , plant seeds have played an important role in the development of the human civilization . Even today, s e e ds of a few crop s p e c i e s , s uc h as the cereals and legume s, are the primary s o u r c e of most human food , and the predominant commodity in international agriculture. Owing to their great importance as food for human s and in international trade , seeds have been a favorite object of s t u d y by developmental biologists and physiologi sts , nutritionist s and chem i sts . A wealth of useful information i s available on th e biology of seed s .

Despite a half century of structural, biophysical and biochemical investigations of ribonucleic acids, they are still mysterious. RNAs stand at fertile crossroads of disciplines, integrating concepts from genomics, proteomics, dynamics as well as biochemistry and molecular biology. From 20 years it is clear, that genetic regulation of eukaryotic organisms has been misunderstood for the last years that the expression of genetic information is effected only by proteins. Basic understanding of nucleic acids has enhanced our foundation to probe novel biological functions. This is especially evident for RNA molecules whose functionality, maturation, and regulation require formation of correct secondary structure through encoded base-pairing interactions.

It has been more than five years since the appearance of the first edition of Nitric Oxide Protocols. According to Medline, more than 32,500 publications dealing with nitric oxide have appeared in the primary literature in the int- vening time from 1999 to April 2004. These numbers attest to the continuing vitality of a field dealing with a deceptively simple, although extremely int- esting and promiscuous molecule, nitric oxide. Despite its apparent chemical simplicity, nitric oxide continues to amaze, with an extremely wide spectrum of functions and effects. In particular, the last few years have witnessed an explosion of nonclassical effects, involving the direct interaction of nitric - ide and related oxidized products with proteins to yield such novel combi- tions as nitrosylated and nitrated proteins. Another emergent area has been that of NO s clinical applications, including interesting developments related to the virus-mediated expression of nitric oxide synthase and the use of nitric oxide in gene therapy. In Nitric Oxide Protocols, I have gathered chapters dealing with the some of the latest methodologies for the measurement of nitric oxide. Many of these deal with quantitation in biological fluids or tissues, and they cover a wide spectrum of technologies, including capillary electrophoresis, microcoaxial electrodes, the in vivo measurement of nitric oxide in exhaled air, confocal microscopy, gas chromatography mass spectroscopy, in situ hybridization, and real-time polymerase chain reaction."

Historically, scientists and laymen have regarded salinity as a hazar dous, detrimental phenomenon. This negative view was a principal reason for the lack of agricultural development of most arid and semi arid zones of the world where the major sources of water for biological production are saline. The late Hugo Boyko was probably the first scientist in recent times to challenge this commonly held, pessimistic view of salinity. His research in Israel indicated that many plants can be irrigated with saline water, even at seawater strength, if they are in sandy soil - a technique that could open much barren land to agriculture. This new, even radical, approach to salinity was clearly enunciated in the book he edited and most appropriately entitled 'Salinity and Aridity: New Approaches to Old Problems' (1966). A decade later, three members of the United States National Science Foundation (NSF), Lewis Mayfield, James Aller and Oskar Zaborsky, formulated the 'Biosaline Concept'; namely, that poor soils, high solar insolation and saline water, which prevail in arid lands, should be viewed as useful resources rather than as disadvantages, and that these resources can be used for non-traditional production of food, fuels and chemicals. The First International Workshop on Biosaline Research was con vened at Kiawah Island, South Carolina, in 1977 by A. San Pietro."

This book was developed from the proceedings of the 2nd North American Tan nin Conference held in Houghton, Michigan, June, 1991. The objective of this con ference was to bring together people with a common interest in plant polyphenols and to promote interdisciplinary interactions that will lead to a bet ter understand ing of the importance of these substances. Another objective of this conference was to extend the 'tannin family' by making special efforts to encourage participation by scientists outside the United States, obtain more coverage of the hydrolyzable tannins, and further broaden the scope of coverage from the initial concentration on forestry and forest products. Com parison of the contents of this book with 'Chemistry and Significance of Condensed Tannins' that resulted from the proceedings of the 1st North American Tannin Conference shows the degree that these objectives were met. In developing the second conference, care was taken to assure that this book extends rather than duplicates the coverage of the first conference. Therefore, the two books should be taken together to obtain an up to date coverage of the broad area of chemistry and significance of plant polyphenols. Our thanks go to the authors who so kindly contributed chapters and so pa tiently responded to our requests. We thank the Conference Assistance Staff of Michigan Technological University for their help in planning and conducting the conference."

We present here the second issue devoted entirely to the spin-labeling technique as part of Biological Magnetic Resonance. Volume 14 commemorates a modifi- tion in our editorial policy with the retirement of my esteemed coeditor, Jacques Reuben. From thisjuncture into the future, each issue will focus on some special topic in magnetic resonance. Each volume will be organized in most cases by guest editors, for example forthcoming issues will address the following topics: in vivo magnetic resonance (P. Robitaille and L. J. Berliner, eds. ) Modern techniques in proton NMR ofproteins (R. Krishna and L. J. Berliner, eds. ) Instrumental techniques of EPR (C. Bender and L. J. Berliner, eds. ) Thecurrent volume, Spin Labeling: The NextMillennium, presents an excellent collection of techniques and applications that evolved during the past decade since the last volume, volume 8 (1989). Someobvious omissions, such as multiquantum EPR and very high-frequency FT-ESR were unfortunately not possible for this volume. Perhaps they will appear in Spin Labeling: 2001. Lastly it is a pleasure to honor two scientists whose contributions were both pioneering and pivotal to the spin label technique: Professor Eduard G. Rozantsev (Moscow), whose synthetic feats in nitroxyl chemistry set the broad stage for a versatile catalog of labels; and Professor Harden M. McConnell, last year's Int- national ESR (EPR) Society Gold Medalist, who conceived and developed the spin label technique to address many biological problems (proteins, enzymes, m- branes, cells, immune response, etc. ).

Rinie Hofstra has been a member of the Department of Plant Physiology, University of Groningen, the Netherlands, for 24 years. The nearer we came to 31 March 1985, her 65th birthday, the more we all realized how we would miss her - not only scientifically, but also socially. She left her mark on both research and teaching, always with an open mind and willing to change. After her PhD Thesis on 'Nitrogen Metabolism in Tomato Plants' she first continued working in that field, but soon started a joint project with the Department of Plant Ecology on hemiparasites. She then became involved in carbon metabolism, which resulted in her giving a Biotrop Course on C /C metabolism in 3 4 Indonesia. Her own research group, originally working on 'Nitrogen Metabolism', soon embraced 'Energy and Nitrogen Metabolism', as the research on respiration became more and more important. In running her group she showed all sides of her person. She used to stimulate and encourage everyone around her and to integrate the various lines of research. At the same time she always had an open mind for the opinion of all members of her group. And together they regularly criticized and evaluated the various projects and decided how to continue.

The first contribution describes apolar and polar molecular fossils and, in particular biomarkers, along the lines usually followed in organic chemistry textbooks, and points to their bioprecursors when available. Thus, the apolar compounds are divided in linear and branched alkanes followed by alicyclic compounds and aromatic and heterocyclic molecules, and, in particular, the geoporphyrins. The polar molecular fossils contain as functional groups or constituent units ethers, alcohols, phenols, carbonyl groups, flavonoids, quinones, and acids, or are polymers like kerogen, amber, melanin, proteins, or nucleic acids. The final sections discuss the methodology used and the fundamental processes encountered by the biomolecules described, including diagenesis, catagenesis, and metagenesis. The second contribution covers the distribution of phthalides in nature and the findings in the structural diversity, chemical reactivity, biotransformations, syntheses, and bioactivity of natural and semisynthetic phthalides.

Advances in Aggregation Induced Emission Materials in Biosensing and Imaging for Biomedical Applications - Part B, Volume 185 presents many aspects of AIE materials that can help future investigators, researchers, students and stakeholders perform research with ease. This volume covers various topics, including tissue and protein fibrils imaging by AIE active molecules, theranostic and photodynamic therapy applications of AIE materials for cancer cell treatment, and AIE active polymers and MOF materials for biological applications. Fluorescence-based monitoring and diagnosis platforms furnish extensive insights into the molecular mechanisms of cellular processes, helping us precisely guide therapeutics.

Basophils and mast cells are similar but unique secretory cells with a well-documented role in immediate-hypersensitivity reactions. The presence of these cells in various cell mediated hypersensitivity reactions, in tissues of multiple diseases, and as a component of the host reaction to injury and repair in numerous circumstances is well known. Release of stored and newly generated mediators of inflammation from basophils and mast cells contributes to the cascade of pathogenetic events in circumstances under which these release reactions occur. Despite insights acquired through studies of these pathologic events, the role of basophils and mast cells and their secretory products in health is not known. In this book, I review much of the structural information regarding basophils and mast cells of multiple species. Ultrastructural studies of rat mast cells historically precede and quantitatively exceed similar studies of basophils and mast cells of other species. Therefore, I first review these background studies as an entity. Then I discuss the contents of two prominent organelles-granules and lipid bodies-in basophils and mast cells of several species. The ultrastructural morphology of basophils and mast cells in three species is presented in detail to establish appropriate guidelines for their recognition and to provide general rules for analysis which are appropriate for the identification of these cells in other species as well."

Membranes are highly dynamic and operate not only as inert boundaries, but the packages they carry around in a cell are well addressed fro appropriate delivery. This holds for a variety of endomembrane systems engaged in exo- and endocytosis, for organelles along the biosynthetic pathway, phagosomes, and lysosomes. It also holds for the establishment of functional surface properties. Cell pairing (conjugation) phenomena are a good model for the problem of how a cell can discriminate between "self" and "non-self." On the other hand parasitic sporozoa developed to experts in masking their molecular sur-"face"by frequent shedding of their variant antigens.
The discovery of their glycosyl-phosphatidylinositol (GPI) anchor has led to the discovery, in polar epithelial cells, of a specific targeting mechanism for GPI-anchored surface glycoproteins. Over one hundred such proteins have been detected in metazoans since then.
Many of these basic aspects are dealt with in this book using quite different methodical approaches. Of course, there are many more aspects previously known from metazoan systems and such aspects then had to be verified also for Protozoa systems and such aspects then had to be verified also for protozoa. In this context, it is fascinating to see how basic cellular functions are maintained - with variations of the basic theme - throughout evolution.
However, sometimes cell biologists dedicated to work with protozoa have to live with a regrettable phenomenon. Colleagues working with "higher" eukaryotic cells are frequently unaware of the fact that the primary input may have come from work with protozoa. Some phenomena may even be rediscovered inadvertently. In this sense, this book should address not only colleagues working with protozoa but also many of our fellow cell biologists working with metazoan cells.

This volume aims to extract and summarize all information about CAK by pointing out commonly accepted facts and unresolved issues. It takes the reader from yeast to mammals and describes all areas that CAK is thought to be involved in. This volume is designed to serve newcomers to the field as well as specialists; any person interested in cell growth, signal transduction and cancer will find this a useful tool to own.
