There has been no mechanistic explanation for evolutionary change consistent with phylogeny in the 150 years since the publication of 'Origins'. As a result, progress in the field of evolutionary biology has stagnated, relying on descriptive observations and genetic associations rather testable scientific measures. This book illuminates the need for a larger evolutionary-based platform for biology. Like physics and chemistry, biology needs a central theory in order to frame the questions that arise, the way hypotheses are tested, and how to interpret the data in the context of a continuum.The reduction of biology to its self-referential, self-organized properties provides the opportunity to recognize the continuum from the Singularity/Big Bang to Consciousness based on cell-cell communication for homeostasis.

This book discusses oxidative stress and hormesis from the perspective of an evolutionary ecologist or physiologist. In the first of ten chapters, general historical information, definitions, and background of research on oxidative stress physiology, hormesis, and life history are provided. Chapters 2-10 highlight the different solutions that organisms have evolved to cope with the oxidative threats posed by their environments and lifestyles. The author illustrates how oxidative stress and hormesis have shaped diversity in organism life-histories, behavioral profiles, morphological phenotypes, and aging mechanisms. The book offers fascinating insights into how organisms work and how they evolve to sustain their physiological functions under a vast array of environmental conditions.

This book provides a knowledge-based view to the dynamic capabilities in an organization. The author integrates two existing views on gaining competitive advantage: the Knowledge View which suggests that the capability of organizations to learn faster than competitors is the only source of competitiveness; and the Dynamic Capability View which speculates that a fi rm's competitive advantage rests on it's ability to adapt to changes in the business environment. Using the IT sector in India as a case study, this book provides and tests a new framework-Knowledge-Based Dynamic Capabilities-in the prediction of competitive advantage in organizations.

Authoritative and practical, Embryo Culture: Methods and Protocols seeks to aid scientists in the further study of this crucially important field of embryology and assisted reproductive technologies.

This book highlights the results from over a year of ethnobotanical research in a rural and an urban community in Jamaica, where we interviewed more than 100 people who use medicinal plants for healthcare. The goal of this research was to better understand patterns of medicinal plant knowledge, and to find out which plants are used in consensus by local people for a variety of illnesses. For this book, we selected 25 popular medicinal plant species mentioned during fieldwork. Through individual interviews, we were able to rank plants according to their frequency of mention, and categorized the medicinal uses for each species as "major" (mentioned by more than 20% of people in a community) or "minor" (mentioned by more than 5%, but less than 20% of people). Botanical identification of plant specimens collected in the wild allowed for cross-linking of common and scientific plant names. To supplement field research, we undertook a comprehensive search and review of the ethnobotanical and biomedical literature. Our book summarizes all this information in detail under specific sub-headings.

This book aims to clarify the potential association between frailty and cardiovascular disease in older people. Covering the biological as well as the clinical point of view, it allows researchers and clinicians to discover the significance of this topic. The contributions cover the most important aspects in the potential relationship between frailty and cardiovascular disease. In particular, authoritative authors in this field have clarified the definition and the epidemiology of frailty and cardiovascular disease in older people. A large part of the volume is dedicated to the biological mechanisms of frailty and cardiovascular disease, trying to find those in common between these two conditions. Since this book is dedicated to both researchers and clinicians, we have proposed some chapters to the importance of comprehensive geriatric assessment in the evaluation and treatment of cardiovascular diseases and frailty. In this regard, the importance of geriatric evaluation in cardiac surgery for older people is well covered. Finally, the importance of cardiac rehabilitation and physical exercise is summarized, being, actually, the most important treatments for both frailty and cardiovascular disease. Written by many well-known and widely published experts in their respective fields, this book will appeal to a wide readership such as researchers in the field and clinicians, especially suited in geriatric medicine and cardiology who, every day, face frail older patients.

In mammals, the major factors involved in the regulation of body growth are known: insulin-like growth factors (IGF) are key regulators of somatic growth. Growth hormone (GH), secreted by the pituitary gland, directly regulates circulating levels of IGF-I, which is the major coordinator of spatio-temporal growth of the organism. In humans, growth is even more complex, involving a number of specific characteristics not found in other species. These include rapid intrauterine growth, deceleration just after birth, a mid-childhood growth spurt, a second deceleration before puberty, an adolescent growth spurt, and finally full statural growth, which is seen somewhat later. The combined knowledge concerning the endocrine and paracrine aspects of growth have led to the introduction of treatment regimens, most effective in GH-deficient children. However, size depends on the combination of a number of genetic factors, and there remain several aspects of this complex process still poorly understood.

One of the major questions in the evolution of animals is the transition from unicellular to multicellular organization, which resulted in the emergence of Metazoa through a hypothetical Urmetazoa. The Comparative Embryology of Sponges contains abundant original and literary data on comparative embryology and morphology of the Porifera (Sponges), a group of 'lower Metazoa'. On the basis of this material, original typization of the development of Sponges is given and the problems concerning origin and evolution of Porifera and their ontogenesis are discussed. A morphogenetic interpretation of the body plan development during embryogenesis, metamorphosis and asexual reproduction in Sponges is proposed. Special attention is given to the analysis of characteristic features of the ontogenesis in Porifera. The book pursues three primary goals: 1) generalization of all existing information on individual development of sponges, its classification and a statement according to taxonomical structure of Porifera; 2) revealing of heterogeneity of morphogenesis and peculiarities of ontogeneses in various clades of Porifera, and also their correlations with the organization, both adult sponges, and their larvae; 3) revealing homology of morphogeneses in both Porifera and Eumetazoa, testifying to the general evolutionary roots of multicellular animals, and peculiar features of sponges' morphogeneses and ontogenesis. This book will be of interest to embryologists, zoologists, morphologists and researchers in evolutionary biology.

The field of stem cell biology is geared towards translation into clinical practice through in vitro tissue production and regeneration therapy. Since the discovery of adult neurogenesis, much attention has been put on the study of differentiation of stem cells into neural cell types and the development of model systems for stroke and neurodegenerative diseases.

In addition to chapters on therapeutic applicability of embryonic, very small-embryonic like, mesenchymal stem and neural progenitor cells, this book covers signalling mechanisms guiding induction to differentiation and cell diversification. Furthermore, fundamental aspects of stem cell biology and neurogenesis, such as the importance of proliferation induction, programmed cell death and the function of glia in differentiation of stem cells and development of neuronal circuits, are also highlighted. In vitro cultures of embryonic, mesenchymal and neural stem cells as well as mobilization of endogenous stem and precursor cells for brain repair and replacement therapy in neurological disorders are important issues of this book.

Each chapter is written by researchers who are leaders in the field and provides an invaluable resource for information on the most current advances in the field and possible therapeutic applications, with discussions of controversial issues and areas of emerging importance. By providing an up-to-date and critical view of the state of Science, we hope that this book shall be a base for exciting scientific ideas regarding functions and therapeutic applications of stem cells in the adult brain. The book is directed to neuroscientists, physicians, students and all who are engaged and interested in the exciting and rapidly expanding field of modern neuroscience and stem cell biology.

Global climate change is bound to create a number of abiotic and biotic stresses in the environment, which would affect the overall growth and productivity of plants. Like other living beings, plants have the ability to protect themselves by evolving various mechanisms against stresses, despite being sessile in nature. They manage to withstand extremes of temperature, drought, flooding, salinity, heavy metals, atmospheric pollution, toxic chemicals and a variety of living organisms, especially viruses, bacteria, fungi, nematodes, insects and arachnids and weeds. Incidence of abiotic stresses may alter the plant-pest interactions by enhancing susceptibility of plants to pathogenic organisms. These interactions often change plant response to abiotic stresses. Plant growth regulators modulate plant responses to biotic and abiotic stresses, and regulate their growth and developmental cascades. A number of physiological and molecular processes that act together in a complex regulatory network, further manage these responses. Crosstalk between autophagy and hormones also occurs to develop tolerance in plants towards multiple abiotic stresses. Similarly, biostimulants, in combination with correct agronomic practices, have shown beneficial effects on plant metabolism due to the hormonal activity that stimulates different metabolic pathways. At the same time, they reduce the use of agrochemicals and impart tolerance to biotic and abiotic stress. Further, the use of bio- and nano-fertilizers seem to hold promise to improve the nutrient use efficiency and hence the plant yield under stressful environments. It has also been shown that the seed priming agents impart stress tolerance. Additionally, tolerance or resistance to stress may also be induced by using specific chemical compounds such as polyamines, proline, glycine betaine, hydrogen sulfide, silicon, -aminobutyric acid, -aminobutyric acid and so on. This book discusses the advances in plant performance under stressful conditions. It should be very useful to graduate students, researchers, and scientists in the fields of botanical science, crop science, agriculture, horticulture, ecological and environmental science.

More than two thirds of all living organisms described to date belong to the phylum Arthropoda. But their diversity, as measured in terms of species number, is also accompanied by an amazing disparity in terms of body form, developmental processes, and adaptations to every inhabitable place on Earth, from the deepest marine abysses to the earth surface and the air. The Arthropoda also include one of the most fashionable and extensively studied of all model organisms, the fruit-fly, whose name is not only linked forever to Mendelian and population genetics, but has more recently come back to centre stage as one of the most important and more extensively investigated models in developmental genetics. This approach has completely changed our appreciation of some of the most characteristic traits of arthropods as are the origin and evolution of segments, their regional and individual specialization, and the origin and evolution of the appendages. At approximately the same time as developmental genetics was eventually turning into the major agent in the birth of evolutionary developmental biology (evo-devo), molecular phylogenetics was challenging the traditional views on arthropod phylogeny, including the relationships among the four major groups: insects, crustaceans, myriapods, and chelicerates. In the meantime, palaeontology was revealing an amazing number of extinct forms that on the one side have contributed to a radical revisitation of arthropod phylogeny, but on the other have provided evidence of a previously unexpected disparity of arthropod and arthropod-like forms that often challenge a clear-cut delimitation of the phylum.

Plant dormancy involves synchronization of environmental cues with developmental processes to ensure plant survival; however, negative impacts of plant dormancy include pre-harvest sprouting, non-uniform germination of crop and weed seeds, and fruit loss due to inappropriate bud break. Thus, our continued quest to disseminate information is important in moving our understanding of plant dormancy forward and to develop new ideas for improving food, feed, and fiber production and efficient weed control, particularly under global climate change. Proceeding from the 5th International Plant Dormancy Symposium will provide an overview related on our current understanding of how environmental factors impact cellular, molecular, and physiological processes involved in bud and seed dormancy, and perspectives and/or reviews on achievements, which should stimulate new ideas and lines of investigation that increase our understanding of plant dormancy and highlight directions for future research.

Ever wondered why your life and health can sometimes be so hard to control? Or why it seems so easy for other people? Mark Hanson and Lucy Green draw on their years of experience as scientists and educators to cut through the usual information on genetics and lifestyle to reveal the secrets of early development which start to make each of us unique, during our first 1,000 days from the moment of conception. Some surprising discoveries, based on little-known new research, show how events during our first 1,000 days make each of us who we are and explain how we control our bodies, processes that go way beyond just the genes which we inherited. Provoking new ways of thinking about being parents, this book empowers individuals and society to give the next generation the gift of a good start to life and future health.

This book focuses on the intersection between cell cycle regulation and embryo development. Specific modifications of the canonical cell cycle occur throughout the whole period of development and are adapted to fulfil functions coded by the developmental program. Deciphering these adaptations is essential to comprehending how living organisms develop. The aim of this book is to review the best-known modifications and adaptations of the cell cycle during development. The first chapters cover the general problems of how the cell cycle evolves, while consecutive chapters guide readers through the plethora of such phenomena. The book closes with a description of specific changes in the cell cycle of neurons in the senescent human brain. Taken together, the chapters present a panorama of species - from worms to humans - and of developmental stages - from unfertilized oocyte to aged adult.

Aging is the progressive decline in biological functions over time. This decline targets macromolecules, cells, tissues and, as a consequence, whole organisms. Despite considerable progress in the development of testable hypothesis concerning aging in an evolutionary context, a unifying theory of the molecular/physiological mechanistic causes of aging has not been reached. In fact, is it not clear to what extent aging is a programmed or stochastic process. This book takes the reader from unicellular bacterial deterioration via senescence in yeast and worms to aging in rodents and humans, allowing a comparative view on similarities and differences in different genetic model systems. The different model systems are scrutinized in the light of contemporary aging hypothesis, such as the free radical and genomic instability theories.

As a result of the key advances made more than 30 years ago, specifically the ability to isolate islets of Langerhans from the pancreas, the ability to measure insulin accurately by immunoasay, and the development of microchemical techniques for studying cells and their components, many research volumes, symposium reports, and original papers have been produced. This explosion of interest has probably had at least three stimuli:

1. the inherent scientific interest in understanding secretion of the pancreatic -cell
2. the -cells relevance to a very common disease
3. the availability of funding from specific sources related to diabetes research, for instance, Juvenile Diabetes Foundation International and the British Diabetic Association.

As a result of all this activity, detailed scientific literature including research reviews are readily available.
Surprisingly enough, there are relatively few attempts to summarize this great bulk of knowledge in a way that is accessible to the newcomer to this field and this book is intended to bridge this gap.

Only in recent times has the possibility of growing and implanting replacement teeth, made from one s own cells, moved into the realm of realistic possibilities; however, the molecular and cellular mechanisms of tooth development must be studied in a range of vertebrates, from zebrafish to mice, so that evolutionarily conserved network kernels, which will define the cellular states of generic vertebrate tooth development, can be recognized. In "Odontogenesis: Methods and Protocols," experts in the field examine techniques to approach this burgeoning field. This detailed volume includes chapters on the detection of tooth development gene expression, both at the RNA and protein level, current approaches to the manipulation of gene expression levels and subsequent analysis of tooth phenotypes, as well as chapters concerning current efforts to get living tooth implants working without waiting for a full understanding of the developmental pathways at the molecular level. Written in the highly successful "Methods in Molecular Biology " series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips for troubleshooting and avoiding known pitfalls.

Practical and easy to use, "Odontogenesis: Methods and Protocols" aims to help researchers move forward toward the ultimate goal of getting a bioengineered tooth into the patient s mouth.
