This volume covers the current knowledge base on the role of signaling and environmental pathways that control the normal development of germline stem cells, meiotic progression of oocytes, events of oocyte maturation and fertilization, and the birth of an embryo. Germ cells are uniquely poised to sustain life across generations through the fusion of oocyte and sperm. Because of the central importance of germ cells to life, much work has been dedicated to obtaining a clear understanding of the molecular and signaling events that control their formation and maintenance. Germ cells are set aside from somatic cells in the embryo and go through specialized meiotic cell cycles as the animal matures. These cell cycles are interspersed with long periods of arrest. In human females, meiosis I is initiated in the fetus. At birth, oocytes are arrested in meiosis I; after puberty, every month an oocyte initiates meiosis II - ovulation. Upon sperm availability these cells are fertilized, generate an embryo, and the cycle-of-life continues. During meiotic I progression and arrest, the fitness of oocytes and their progeny are likely influenced by environmental cues and signaling pathways. A lot of recent work has focused on understanding the mechanisms that regulate oocyte fitness and quality in humans and vertebrates. Much of our understanding on the events of meiosis I and germline stem cell populations comes from work in invertebrates, wherein the germline stem cells produce oocytes continuously through adult development. In both inverbrates and vertebrates nutritional and signaling pathways control the regulation of stem cells in such a manner so as to couple production of gametes with the nutritional availability. Additionally, mature oocytes arrest both in meiosis I and meiosis II, and signaling and nutritional pathways have been shown to regulate their formation, and maintenance, such that despite long periods of arrest, the oocyte quality is assured and errors in chromosome segregation and varied cytoplasmic events are minimal.

Biological membranes play a central role in cell structure, shape and functions. However, investigating the membrane bilayer has proved to be difficult due to its highly dynamic and anisotropic structure, which generates steep gradients at the nanometer scale. Due to the decisive impact of recently developed fluorescence-based techniques, tremendous advances have been made in the last few years in our understanding of membrane characteristics and functions. In this context, the present book illustrates some of these major advances by collecting review articles written by highly respected experts. The book is organized in three parts, the first of which deals with membrane probes and model membranes. The second part describes the use of advanced quantitative and high-resolution techniques to explore the properties of biological membranes, illustrating the key progress made regarding membrane organization, dynamics and interactions. The third part is focused on the investigation of membrane proteins using the same techniques, and notably on the membrane receptors that play a central role in signaling pathways and therapeutic strategies. All chapters provide comprehensive information on membranes and their exploration for beginners in the field and advanced researchers alike.

Mitochondria as a Key Intracellular Target of Thallium Toxicity presents a new hypothesis that explains the decrease in antioxidant defense of thallium poisoning and proposes a new model for studying the transport of inorganic cations across the inner mitochondrial membrane. Readers will learn about the toxicity of thallium and its compounds, the toxicology of thallium, the toxic thallium effects on cells, and the effects of thallium on mitochondria. In addition, the book lists the pathways and mechanisms of thallium transport into cells and mitochondria, including information on toxicity that has been analyzed at both the cellular and subcellular levels. The increase in human contact with the toxic trace element thallium is associated with industry development, the release of metal into the environment from various rocks, and the use of special isotope techniques for studying the vascular bed.

Intriguing new findings on how genes and environments work together through different stages of life take the spotlight in this significant collection. Studies from infancy to late adulthood show both forces as shaping individuals' relationships within family and non-family contexts, and examine how these relationships, in turn, continue to shape the individual. Transitional periods, in which individuals become more autonomous and relationships and personal identities become more complicated, receive special emphasis. In addition, chapters shed light on the extent to which the quantity and quality of genetic and environmental influence may shift across and even within life stages. Included in the coverage: Gene-environment interplay in parenting young children. The sibling relationship as a source of shared environment. Gene-environment transactions in childhood and adolescent problematic peer relationships. Toward a developmentally sensitive and genetically informed perspective on popularity. Spouse, parent, and co-worker: roles and relationships in adulthood. The family system as a unit of clinical care: the role of genetic systems. Behavioral geneticists, clinical psychologists, and family therapists will find in Gene-Environment Interplay in Interpersonal Relationships across the Lifespan a window into current thinking on the subject, new perspectives for understanding clients and cases, and ideas for further study.

Examining stem cell biology from a philosophy of science perspective, this book clarifies the field's central concept, the stem cell, as well as its aims, methods, models, explanations and evidential challenges. The first chapters discuss what stem cells are, how experiments identify them, and why these two issues cannot be completely separated. The basic concepts, methods and structure of the field are set out, as well as key limitations and challenges. The second part of the book shows how rigorous explanations emerge from stem cell experiments, and compares these to other kinds of scientific explanation. Model organisms, the role of genes, and the significance of collaboration are also discussed. The last part of the book considers relations to systems biology and clinical medicine, arguing that both the mathematical models of the former, and ethical principles of the latter, are necessary for stem cell biology to deliver on its promises.

In plant cells, the plasma membrane is a highly elaborated structure that functions as the point of exchange with adjoining cells, cell walls and the external environment. Transactions at the plasma membrane include uptake of water and essential mineral nutrients, gas exchange, movement of metabolites, transport and perception of signaling molecules, and initial responses to external biota. Selective transporters control the rates and direction of small molecule movement across the membrane barrier and manipulate the turgor that maintains plant form and drives plant cell expansion. The plasma membrane provides an environment in which molecular and macromolecular interactions are enhanced by the clustering of proteins in oligimeric complexes for more efficient retention of biosynthetic intermediates, and by the anchoring of protein complexes to promote regulatory interactions. The coupling of signal perception at the membrane surface with intracellular second messengers also involves transduction across the plasma membrane. Finally, the generation and ordering of the external cell walls involves processes mediated at the plant cell surface by the plasma membrane. This volume is divided into three sections. The first section describes the basic mechanisms that regulate all plasma membrane functions. The second describes plasma membrane transport activity. The final section of the book describes signaling interactions at the plasma membrane. These topics are given a unique treatment in this volume, as the discussions are restricted to the plasma membrane itself as much as possible. A more complete knowledge of the plasma membrane's structure and function is essential to current efforts to increase the sustainability of agricultural production of food, fiber, and fuel crops.

A number of chapters present the most novel research on testicular and epididymal functions or on more general fields of hormone action and molecular cell biology as it is now a tradition. However, exceptionally, the book also contains several chapters dealing with the "Approaches and Tools in the Third Millenium." The unusual inclusion of technologies as such in the 2000 edition of the workshop was an absolute necessity, as these technologies are revolutionizing the fields of biology and medicine and, in many instances, how to do research. This volume gives the scientific community essential information about the very latest technical developments and their potential for future progress.

"After being frequently urged to write upon this subject, and as often declining to do it, from apprehension of my own inability, I am at length compelled to take up the pen, however unqualified I may still feel myself for the task. " William Withering, M. D. ' I have yet to find a description or a quote that better summanzes my initial ambivalence towards embarking on such an endeavor as partici pating in putting together this monograph. The impetus for The Red-Cell has been a simple, genuine Membrane: A Model for Solute Transport desire to bring together an authoritative account of the' 'state of the art and knowledge" in the red-ceIl-membrane transport field. In particular, it seems important to emphasize the pivotal role the red cell has played for several decades in the discovery and the elucidation of mechanisms of plasma-membrane transport processes. It is only with such knowledge that we can hope to push ahead and make progress in this exciting, multifaceted area. Eventually, one hopes to not only further our knowledge of red cells, but apply the newly gained insights to any other of the plasma membrane. cell with the common denominator In this compendium of reviews, the reader will find that the term model will take on a variety of gists and meanings. In some chapters, the red cell has been chosen as a model membrane solely on the basis of its preeminent design and simplicity."

Agrobacterium tumefaciens is a soil bacterium that for more than a century has been known as a pathogen causing the plant crown gall disease. Unlike many other pathogens, Agrobacterium has the ability to deliver DNA to plant cells and permanently alter the plant genome. The discovery of this unique feature 30 years ago has provided plant scientists with a powerful tool to genetically transform plants for both basic research purposes and for agricultural development. Compared to physical transformation methods such as particle bomba- ment or electroporation, Agrobacterium-mediated DNA delivery has a number of advantages. One of the features is its propensity to generate a single or a low copy number of integrated transgenes with defined ends. Integration of a single transgene copy into the plant genome is less likely to trigger "gene silencing" often associated with multiple gene insertions. When the first edition of Agrobacterium Protocols was published in 1995, only a handful of plants could be routinely transformed using Agrobacterium. Agrobacterium-mediated transformation is now commonly used to introduce DNA into many plant species, including monocotyledon crop species that were previously considered non-hosts for Agrobacterium. Most remarkable are recent developments indicating that Agrobacterium can also be used to deliver DNA to non-plant species including bacteria, fungi, and even mammalian cells.

Since the first international meeting on Vitamin B6 involvement in catalysis took place in 1962, there have been periodic meetings every three or four years. In 1990, scientists studying another cofactor, PQQ, which had already attracted the scientific community's interest for its possible involvement in amino acid decarboxylation and reactions involving amino groups, joined forces with those investigating pyridoxal phosphate-dependent enzymes. Since then, the international PQQ/quinoproteins meetings have been held jointly. In the years following the original meeting 37 years ago in Rome, Italy, the scientific gatherings have taken place in Moscow, Russia (1966); Nagoya, Japan (1967); Leningrad (St. Petersburg), Russia (1974); Toronto, Canada (1979); Athens, Greece (1983); Turku, Finland (1987); Osaka, Japan (1990); and Capri, Italy (1996). For the first time in the history of these symposia, the international meeting was held in the United States, from October 31 through November 5, 1999, in Santa Fe, New Mexico. The scientific program focus shifted significantly beyond the original emphasis on catalysis to aspects such as cellular and genetic regulation of events involving proteins that require pyridoxal phosphate or quinoproteins. The growing awareness of the involvement of these proteins in biotechnology processes and fundamental physiological events, as well as their implication in diseases, was also represented, with emphasis on the molecular basis of these events. The meeting was symposium S278, sponsored by the International Union of Biochemistry and Molecular Biology (IUBMB).

Dr. Spirin is a world authority on ribosomes and has published two earlier books in this area in English.

Ribosomes are important in protein synthesis, which is currently a hot topic in many different areas of research.

In Bilayer Lipid Membranes. Structure and Mechanical Properties the authors use new methods of measurement, which they have themselves developed, to present an analysis of the relation between membrane structure and viscoelastic properties, in particular in the transversal direction. Hianik and Passechnik's approach is fundamentally different from the usual one, in that they analyze lipid bilayer dynamics during various modes of deformation, arriving at a new, three-layer' model that accounts for the great heterogeneity of biomembranes. The macroscopic parameters of membranes have been measured using a wide variety of methods, leading to a discussion of the correlations between the parameters. There is also an extensive discussion of the dynamic changes in mechanical properties of lipid bilayers in the course of conformational transition of integral proteins. During the conformational changes of proteins, the structure of a bilayer undergoes a transition, reaching a new, stable membrane state. The book is the first to present a comprehensive analysis of long-distance interaction in lipid bilayers and of molecular mechanisms of mechanoreception. Audience: Scientists and graduate students working in biophysics, membranology, physiology, medicine, pharmacology, bioelectronics, electrochemistry, and colloid chemistry.

Cutting-edge techniques for the analysis of subproteomes from isolation to final characterization and the characterization of posttranslational modifications are also addressed. This useful snapshot of current proteomic techniques is a single source for protocols for the identification and validation of novel biomarkers and targets in cardiovascular diseases.

This book provides detailed and comprehensive information on oxidative damage caused by stresses in plants with especial reference to the metabolism of reactive oxygen species (ROS). In plants, as in all aerobic organisms, ROS are common by-products formed by the inevitable leakage of electrons onto O2 from the electron transport activities located in chloroplasts, mitochondria, peroxisomes and in plasma membranes or as a consequence of various metabolic pathways confined in different cellular loci. Environmental stresses such as heat, cold, drought, salinity, heavy-metal toxicity, ozone and ultraviolet radiation as well as pathogens/contagion attack lead to enhanced generation of ROS in plants due to disruption of cellular homeostasis. ROS play a dual role in plants; at low concentrations they act as signaling molecules that facilitate several responses in plant cells, including those promoted by biotic and abiotic agents. In divergence, at high levels they cause damage to cellular constituents triggering oxidative stress. In either case, small antioxidant molecules and enzymes modulate the action of these ambivalent species.

In depth knowledge of cellular stress will eventually lead to the development of novel therapeutics to prevent or treat related diseases.

'frees contribute a major part of fuel, fodder and fruit, and are an im of bioenergy. They are now needed in large numbers more portant source than ever before for afforestation and social forestry, so that fast-grow ing and multipurpose trees assume great importance. After extensive in discriminate deforestation and rapid depletion of genetic stocks, efforts are now being made to evolve methods for clonal mass propagation of improved and elite trees. Production of short-duration trees with a rapid turnover of biomass, and induction of genetic variability through in vitro manipulation for the production of novel fruit and forest trees, which are high-yielding and resistant to pests and diseases, and trees which display increased photosynthetic efficiency are in demand. These objectives are well within the realm of horticultural and forest biotech nology. Some of the recent advances, such as the regeneration of com plete trees from isolated protoplasts, somatic hybridization, and the Agrobacterium-mediated transformation in various tree species have opened new vistas for the genetic engineering of fruit and forest trees. This book is a continuation of the earlier volume Trees I, and presents 31 chapters on fruit, forest, nut and ornamental trees, such as avocado, pineapple, crabapple, quince, pistachio, walnut, hazelnut, date palm, oil palm, cacao, rubber, maple, sweet-gum, poplars, birches, Chinese tallow, willows, oaks, paper mulberry, rhododendrons, Scots pine, Calabrian pine, Douglas-fir, redwood, ginkgo, cycads and some flowering trees."

This thesis describes the use of biophysical and biochemical methods to prove that calcium has a positive feedback effect on amplifying and sustaining CD3 phosphorylation and should enhance T-cell sensitivity to foreign antigens. The study presented shows that calcium can regulate the signal pathway in cells not only as a secondary messenger but also through direct interactions with the phospholipid bilayer. The approach used in the thesis also represents an important advance, as it couples the use of nuclear magnetic resonance (NMR) to the analysis of signaling phenomena in living cells. Moreover, the thesis optimizes the Nanodisc assembly protocol, which can broaden its range of applications in membrane protein studies. A preliminary study on the structure of dengue virus NS2B-NS3p in complex with aprotinin, which may help to develop new drugs against the dengue virus, is also included.

This title will focus on the study of human interphase chromosomes and its relation to health and disease. Orchestrated organization and human genome function in interphase nuclei at the chromosomal level have been repeatedly shown to play a significant role in a variety of basic biological processes involved in realization and inheritance of genetic information within and between species. Current biomedical sciences of post-genomic era refocus basic and applied studies of interphase nuclei genetics and genomics with special attention to interphase chromosome behavior in health and disease. Additionally, related processes are a target of studies elucidating the role of interphase chromosome behavior during development, chromosome/DNA replication, DNA reparation etc. Studies of interphase nuclei have an appreciable impact on different areas of biomedical sciences such as cell biology, neurobiology, cancer research, developmental biology, epigenetics, cytogenetics, and medical genetics, as a whole. Moreover, development of innovative and emergent technologies to analyze interphase nuclei are closely associated with application of these techniques in clinical, diagnostic and research practice to solve reproductive problems (including infertility and spontaneous abortions), to investigate congenital malformations (including those produced by aneuploidy and other chromosome abnormalities); genetic diseases (including cardiac, immune, neurological and psychiatric diseases), and cancer. This title will serve as a source of new valuable information and promising ideas for a wide audience of professionals in biomedicine including researchers, scientists, and healthcare professionals in human genetics, cytogenetics, and developmental biology.

Over the years there has been growing interest among the scientific community in investigating sleep and how it affects the memory and other brain functions. It is now well established that sleep helps in memory consolidation and induction of neural plasticity, and that short-term deprivation of either total sleep or rapid eye movement sleep alone can induce memory deficits very quickly. Quantitative and qualitative changes in sleep architecture after different training tasks further suggest that discrete memory types may require specific sleep stage/s for optimal memory consolidation, and studies indicate that sleep deprivation alters synaptic plasticity and membrane excitability in the hippocampal neurons and synaptic up-scaling in the cortical neurons. Further, sleep alteration during pregnancy may increase the risk of depression and adversely affect maternal-child relationships, parenting practices, family functioning, and children's development and general wellbeing. This book coherently discusses all these aspects, with a particular focus on the possible role of sleep in memory consolidation and synaptic plasticity. It also highlights the detrimental effects of sleep loss on mental health, the immune system and cognition. This book is a valuable reference resource for students and researchers working in the area of sleep, memory, or neuronal plasticity.
