This book offers comprehensive information on the new and rapidly evolving science of identifying and targeting senescent cells, and on the exciting prospect of new diagnostic and therapeutic opportunities for stopping, and even reversing, the progression of disease and the deterioration of the human body due to ageing. According to recent United Nations data, by 2050 one in six people worldwide will be older than age 65, with peaks rising to one in four people in Europe and North America. Remarkably, the number of persons aged 80 years or older is expected to triple, from 143 million in 2019 to 426 million in 2050. First documented in the 1960s, the concept of cellular senescence as an underlying cause of ageing has been established in the course of the last decade. Using genetically engineered mouse models, researchers have demonstrated that the selective elimination of senescent cells can block and even reverse a number of age-related dysfunctions and pathologies, promoting both better health and longer life in the elderly. These include cardiovascular diseases; neurological disorders; type 1 and type 2 diabetes; inflammatory diseases; fibrosis; geriatric syndromes; chronic diseases resulting in organ dysfunction; the integrity of the musculoskeletal system; and cancer. Some senolytic agents have already progressed into trials. These include UBX0101 for the treatment of osteoarthritis (now in phase II), a cocktail of dasatinib and quercetin for the management of idiopathic pulmonary fibrosis and chronic kidney disease, and ABT-263 in combination with senescence-inducing chemotherapies for the treatment of advanced solid tumours. In addition, the book discusses pathways to early phase clinical trials and translational approaches in medicine and ageing, highlighting new opportunities as well as current limitations, challenges and alternatives. Given its scope, it will benefit a broad audience of advanced educators, researchers, graduate students and practitioners.

The book highlights the therapeutic applications of various stem cells, and introduces readers to thymus stem cells and their applications in the reconstitution of thymic structure and function. It also discusses the significant role of mesenchymal stem cells (MSCs) in the treatment of autoimmune diseases and the use of MSC-derived exosomes in cell-free therapy. Moreover, it explores the application of hematopoietic stem cells in the vasculoprotection of the ischemially injured heart. Further topics include the regenerative potential of ovarian germline stem cells and the significance of endometrial stem cells in the pathogenesis of female reproductive tract diseases. Lastly, the book addresses stem cells from perinatal tissues and their immunoregulatory and differentiation potentials, and summarizes new strategies for targeting cancer stem cells to treat tumors.

As recent articles about "the graying of America" suggest, a demographic revolution is well underway. The number of people living into extreme old age is increasing dramatically. By the year 2050 one in five of the world's population, including the developing countries, will be 65 or older, a fact which presages profound medical, biological, philosophical, and political changes in the coming century.

In Time of Our Lives, Tom Kirkwood unfolds some of the deepest mysteries of medical science while demolishing some of the most persistent misconceptions. He overturns the almost universally held belief that aging is either necessary or inevitable--it isn't--and debunks the idea that there exists a "death gene" that evolved to inhibit population growth. Instead, Kirkwood shows that we age because our genes, evolving at a time when life was "nasty, brutish, and short," placed little priority on the long-term maintenance of our bodies. With such knowledge, along with new insights from genome research, we can devise ways to target the root causes of aging and of age-related diseases such as Alzheimer's and osteoporosis. Expanding the thesis of the "disposable soma," developed over twenty years of research, Kirkwood makes sense of the evolution of aging, explains how aging occurs, and answers fundamental questions like why women live longer than men. He even considers the possibility that human beings will someday have greatly extended life spans or even be free from senescence altogether.

Beautifully written by one of the world's pioneering researchers into the science of aging, Time of Our Lives is a clear, original and, above all, inspiring investigation of a process all of us experience but few of us understand.

Fish accomplish most of their basic behaviors by swimming. Swimming is fundamental in a vast majority of fish species for avoiding predation, feeding, finding food, mating, migrating and finding optimal physical environments. Fish exhibit a wide variety of swimming patterns and behaviors. This treatise looks at fish swimming from the behavioral and ecological perspectives rather than from the more traditional biomechanics, ecomorphology and physiological perspectives used in studies of fish swimming. The book is therefore largely integrative by its own nature, and it includes considerations related to fisheries, conservation and evolution. It is aimed at students and researchers interested in fish swimming from any organismal background, be it biomechanics, ecomorphology, physiology, behavior or ecology.

This seven-volume series is the most extensive treatise on early life histories of the freshwater fishes of North America. It represents the state-of-the-art in fishery biology and provides a systematic approach to the study of early life histories of all the fishes in this region. Each volume contains distinguishing characteristics and a pictorial guide to the families of fishes in the OR Drainage, followed by chapters on the families. This series fills a gap in the literature, providing information on the spawning habitat requirements, reproductive behavior, and ecological relationships during the first few months of life for most species. This fifth volume examines the family Centrarchidae.

The ontogeny of each individual contributes to the physical, physiological, cognitive, neurobiological, and behavioral capacity to manage the complex social relationships and diverse foraging tasks that characterize the primate order. For these reasons Building Babies explores the dynamic multigenerational processes of primate development. The book is organized thematically along the developmental trajectory:conception, pregnancy, lactation, the mother-infant dyad, broader social relationships, and transitions to independence. In this volume, the authors showcase the myriad approaches to understanding primate developmental trajectories from both proximate and ultimate perspectives. These collected chapters provide insights from experimental manipulations in captive settings to long-term observations of wild-living populations and consider levels of analysis from molecule to organism to social group to taxon. Strepsirrhines, New World monkeys, Old World monkeys, apes, and humans are all well-represented. Contributions by anthropologists, microbiologists, psychologists, population geneticists, and other primate experts provide Building Babies a uniquely diverse voice. Building Babies features multi- and trans-disciplinary research approaches to primate developmental trajectories and is particularly useful for researchers and instructors in anthropology, animal behavior, psychology, and evolutionary biology. This book also serves as a supplement to upper-level undergraduate courses or graduate seminars on primate life history and development. In these contexts, the book provides exposure to a wide range of methodological and theoretical perspectives on developmental trajectories and models how researchers might productively integrate such approaches into their own work.

Biological aging as the time-depending general decline of biological systems associated with a progressively increasing mortality risk is a general phenomenom of great significance. The underlying processes are very complex and depending on genetic and environment factors. These factors encode or affect a network of interconnected cellular pathways. In no system this network has been deciphered in greater detail. However, the strategy of studying various biological systems has let to the identification of pathways and specific modules and makes it obvious that aging is the result of different overlapping mechanisms and pathways. Some of these appear to be conserved ("public") among species, others are specific or "private" and only of significance in one or a few organisms. This volume in the series on "Biology of aging and its modulation" specifically focuses on organismic aging. The book covers research on organisms from lower to higher complexity representing examples from very diverse taxa like photosynthetic plants, fungi, sponges, nematodes, flies, birds and mammals. Such a broad treatise of this complex topic provides a comprehensive "flavor" about the current issues dealt with in this rapidly growing scientific discipline.

About 95 per cent of all known animal species are invertebrates. A knowledge of their sexual, reproductive, and developmental biology is essential for the effective management of species that are economically useful to man or are harmful to him, his crops, and livestock. This treatise is the first to cover all aspects of reproduction and development of the entire spectrum of invertebratesterrestrial, marine, freshwater, brackish-water, free-living, and parasitic. The chapters, by leading world experts in their fields, are up-to-date and informative, and suggest a number of problems for future research.

Gives an account of the morphologies of vertebrate respiratory organs and attempts to explicate the basis of the common and different structural and functional designs and stratagems that have evolved for acquisition of molecular oxygen. The book has been written with a broad readership in mind: students of biology as well as experts in the disciplines of zoology, physiology, morphology, biological microscopy, biomedical engineering, and ecology and those that work or may contemplate working on materials and aspects concerning respiration in whole organisms will find it useful. Scientists in earth sciences with particular interest on the outcomes of past interactions between environmental factors (the physical domain) and evolution and adaptation (the biological domain), mechanisms that have set the composition, patterning, and anatomies of extant animal life, will find the book of interest.

From the discovery of Pdx1, the first "master gene" of pancreatic development, to the most recent findings on the role of microRNAs in beta cell homeostasis, the last fifteen years have seen an unprecedented advance in our understanding of the precise development and organization of the many different cell types that make up the pancreas. It is now widely acknowledged that the therapeutic differentiation of stem cells into pancreatic cells is an ambitious endeavor that will not succeed without a thorough understanding of the molecular processes underlying the native development of the organ. This book, aimed at experts and students alike, offers a comprehensive review of the state of the art in both pancreatic development and regeneration. The many strategies to differentiate adult and embryonic stem cells into pancreatic beta cells are also discussed in the context of potential therapeutic interventions for type I diabetes.

The ONLY textbook available on marine mammal physiology, a core topic in Marine Science undergrad teaching Builds on the unique overall theme 'How would you design a marine mammal?' which focuses on what an undergrad student would actually want to know. What would they ask? So rather than "What are the biochemical differences between marine and terrestrial mammals?" the book addresses "How can marine mammals dive for such a long time?" or "How do they stay warm in such cold water?" Organises the Table of Contents into common 'real' student questions. The book thus centres around the point of view of the student. This makes it accessible and student-focused. Consistency across all chapters Provides consistent Power Point slides that teachers can use when they don't know the field well AND that students can use as study guides. Offers Study Questions and future thinking/implications questions. A Driving Question for each chapter is highlighted in a box. A concluding chapter ties up loose ends and consolidates the driving questions from the individual chapters. Contains the contributions of well-respected, prominent scientists in the field. Author bios for each chapter showcase diversity in contributor pool. Focuses on physiological adaptations of marine mammals and connects them with the ecological context, including anthropogenic impacts. Discusses differences that might exist by type of marine mammal, development questions, and behavioral issues.

With the emergence of the new field of evolutionary developmental biology we are witnessing a renaissance of Darwin s insights 150 years after his Origin of Species. Thus far, the exciting findings from evo-devo have only been trickling into college courses and into the domain of non-specialists. With its focus on the human organism, Quirks of Human Anatomy opens the floodgates by stating the arguments of evo-devo in plain English, and by offering a cornucopia of interesting case studies and examples. Its didactic value is enhanced by 24 schematic diagrams that integrate a host of disparate observations, by its Socratic question-and-answer format, and by its unprecedented compilation of the literature. By framing the hows of development in terms of the whys of evolution, it lets readers probe the deepest questions of biology. Readers will find the book not only educational but also enjoyable, as it revels in the fun of scientific exploration.

One in two of us will develop cancer at some point in our lives and yet many of us don't understand how cancers arise. How many different kinds of cancer are there? What treatments are available? What does the future hold in terms of developing new therapies? This book demystifies cancer by explaining the underlying cell and molecular biology in a clear and accessible style. It answers the questions commonly asked about cancer such as what causes cancer and how cancer develops. It explains how DNA makes proteins and how mutations can corrupt those proteins. It also gives an overview of current therapies and how treatments may advance over the next decades, as well as explaining what actions we can take to help prevent cancer developing. Understanding Cancer is an accessible and engaging introduction to cancer biology for any interested reader.

Evolution, Explanation, Ethics and Aesthetics: Towards a Philosophy of Biology focuses on the dominant biological topic of evolution. It deals with the prevailing philosophical themes of how to explain the adaptation of organisms, the interplay of chance and necessity, and the recurrent topics of emergence, reductionism, and progress. In addition, the extensively treated topic of how to explain human nature as a result of natural processes and the encompassed issues of the foundations of morality and the brain-to-mind transformation is discussed. The philosophy of biology is a rapidly expanding field, not more than half a century old at most, and to a large extent is replacing the interest in the philosophy of physics that prevailed in the first two-thirds of the twentieth century. Few texts available have the benefit of being written by an eminent biologist who happens to be also a philosopher, as in this work. This book is a useful resource for seminar courses and college courses on the philosophy of biology. Researchers, academics, and students in evolutionary biology, behavior, genetics, and biodiversity will also be interested in this work, as will those in human biology and issues such as ethics, religion, and the human mind, along with professional philosophers of science and those concerned with such issues as whether evolution is compatible with religion and/or where morality comes from.
