Book Description
The PI3Ks control many key functions in immune cells. PI3Ks phosphorylate PtdIns(4,5)P2 to yield PtdIns(3,4,5)P3. Initially, PI3K inhibitors such as Wortmannin, LY294002 and Rapamycin were used to establish a central role for Pi3K pathway in immune cells. Considerable progress in understanding the role of this pathway in cells of the immune system has been made in recent years, starting with analysis of various PI3K and Pten knockout mice and subsequently mTOR and Foxo knockout mice. Together, these experiments have revealed how PI3Ks control B cell and T cell development, T helper cell differentiation, regulatory T cell development and function, B cell and T cell trafficking, immunoglobulin class switching and much, much more. The PI3Kd inhibitor idelalisib has recently been approved for the treatment of B cell lymphoma. Clinical trials of other PI3K inhibitors in autoimmune and inflammatory diseases are also in progress. This is an opportune time to consider a Research Topic considering when what we have learned about the PI3K signalling module in lymphocyte biology and how this is making an impact on clinical immunology and haematology.

Book Description
Ecotoxiclogical risk from multiple stressors covers any situation where org- isms are exposed to a combination of environmental stressors. These include physical and chemical pollutants as well as other stressors such as parasites and environmental impact (e. g. , climate change or habitat loss). The combi- tion of stressors can result in increased risk to organisms (either additive or synergistic effects) or decreased effects (protective or antagonistic effects). The multiple stressor challenge is an international, multi-disciplinary problem requiring an international, multi-disciplinary approach. The c- rent approach to multiple stressors is to examine one stressor at a time and assume additivity. Little work has been done on combinations of stressors such that potential interactions can be determined. The problem is very complex. Multiple stressors pose a whole spectrum of challenges that range from basic science to regulation, policy and gove- ance. The challenges raise fundamental questions about our understanding of the basic biological response to stressors, as well as the implications of those uncertainties in environmental risk assessment and management. In addition to the great breadth, there is also great depth in the research ch- lenges, largely due to the complexity of the issues. From a basic science point of view, many of the mechanisms and processes under investigation are at the cutting edge of science — involving new paradigms such as genomic ins- bility and bystander effects.

Book Description
This book establishes a bridge between exercise-mediated functional status of autophagy and non-communicable chronic diseases for elucidating and clarifying the corresponding signal pathways and underlying mechanisms. The book consists of 13 chapters focusing on the in-depth discussion on signal pathways for regulating the functional status of autophagy for the prevention, treatment and rehabilitation of chronic diseases, the optimization of exercise intervention strategies for common and frequently-occurring chronic diseases, and the development of exercise mimetic pills for the persons with disability for exercise performance, or the persons without willing to exercise. This book is interesting and will be useful to a wide readership in the various fields of exercise science, exercise fitness, sports medicine, preventive medicine, and functional foods.

Book Description
This book provides the first comprehensive overview of a new scientific discipline termed Geroscience. Geroscience examines the molecular and cellular mechanisms that might explain why aging is the main risk factor for most chronic diseases affecting the elderly population. Over the past few decades, researchers have made impressive progress in understanding the genetics, biology and physiology of aging. This book presents vital research that can help readers to better understand how aging is a critical malleable risk factor in most chronic diseases, which, in turn, could lead to interventions that can help increase a healthy lifespan, or ‘healthspan.’ The book begins with an analysis of the Geroscience hypothesis, as well as the epidemiological underpinnings that define aging as a candidate main risk factor for most chronic diseases. Next, each chapter focuses on one particular disease, or group of diseases, with an emphasis on how basic molecular and cellular biology might explain why aging is a major risk factor for it. Coverage in the book includes: cancer, cardiovascular disease, dementias, stroke, Parkinson's and Alzheimer’s diseases, osteoporosis, arthritis, diabetes asthma, emphysema, kidney disease, vision impairment, and AIDS/HIV. It finishes with a chapter on pain in the elderly and an overview of future steps needed to bring the newly acquired knowledge into the clinic and the public at large.

Book Description
Features that characterize the aging process include the gradual accumulation of cell damage after prolonged exposure to oxidative and inflammatory events over a lifetime. In addition to the accretion of lesions, the intrinsic levels of pro-oxidant and aberrant immune responses are elevated with age. These adverse events are often further enhanced by the chronic and slow progressing diseases that characterize the senescent brain and cardiovascular system. The incidence of some disorders such as Alzheimer's disease and vascular diseases are sufficiently prevalent in the extreme elderly that these disorders can arguably be considered "normal". Aging and Aging-Related Disorders examines the interface between normal and pathological aging, and illustrates how this border can sometimes be diffuse. It explores and illustrates the processes underlying the means by which aging becomes increasingly associated with inappropriate levels of free radical activity and how this can serve as a platform for the progression of age-related diseases. The book provides chapters that examine the interactive relationship between systems in the body that can enhance or sometimes even limit cellular longevity. In addition, specific redox mechanisms in cells are discussed. Another important aspect for aging discussed here is the close relationship between the systems of the body and exposure to environmental influences of oxidative stress that can affect both cellular senescence and a cell’s nuclear DNA. What may be even more interesting to note is that these external stressors are not simply confined to illnesses usually associated with aging, but can be evident in maturing and young individuals. A broad range of internationally recognized experts have contributed to this book. Their aim is to successfully highlight emerging knowledge and therapy for the understanding of the basis and development of aging–related disorders.

Book Description
This textbook presents for the first time a comprehensive body of the latest knowledge in the field of neuropeptides and their action on energy balance. It contains a detailed and comprehensive account of the specific hypothalamic peptides in regards to their roles in energy balance, food intake control and co-morbidities, to better understand the patho-physiology of obesity. The textbook includes an examination the history of the evolution of human society from a thin to the obese phenotype and, within that context, how modern society habits and industrial food production did not respect the evolutionary trait resulting in changes in the energy balance set point. It provides a novel conceptualization of the problem of obesity when considering the biochemistry of peptide hormones and entertaining novel ideas on multiple approaches to the problems of energy balance, as well as demonstrates and explains why alterations in pro-hormone processing are paramount to understand metabolic disease. This text is excellent material for teaching graduate and medical school courses, as well as a valuable resource for researchers in biochemistry, cell, and molecular biology, neuroscientists, physician endocrinologists, and nutritionists.

Book Description
Metabolic Syndrome and Neurological Disorders brings together information on the cluster of common pathologies which cause metabolic syndrome - abdominal obesity linked to an excess of visceral fat, insulin resistance, dyslipidemia and hypertension - to provide a comprehensive and cutting edge exploration of the link between metabolic syndrome and neurological disorders. Metabolic syndrome is recognized to play a role in neurological disorders such as stroke, Alzheimer's disease, and depression. For the first time in book form, Metabolic Syndrome and Neurological Disorders covers the molecular mechanisms thought to underlie this mirror relationship, as well as how lifestyle and other factors such as oxidative stress and inflammation may play a role in the disease. Grounded in a series of epidemiological studies of metabolic-cognitive syndrome, this book will be a valuable reference for researchers, dietitians, nutritionists, and physicians.

Book Description
This volume includes contributions presented at the Second International Sym posium on Nutrition and Cancer, held in Naples, Italy, in October 1998 at the National Tumor Institute "Fondazione Pascale." During the Conference, experts from different disciplines discussed pivotal and timely subjects on the interactions between human nutrition and the development of malignancies. Comparing the themes of this Meeting with those discussed at the First Sympo sium in 1992, the major scientific advancements certainly derive from the extensive use of molecular approaches to perform research in nutrition. Moreover, the fundamental observation of R. Doll and R. Peto (1981), which suggested that at least 35% of all cancers (with large differences among different tumors) might be prevented by dietary regimens, has been definitively confirmed by epidemiological studies. On the other hand, the relationships between diet and cancer are quite intricate and complex; it is difficult, and at the same time not methodologically correct, to reduce them to simple terms. Metabolic and hormonal factors, contaminants and biological agents, and deficiency of specific protective nutrients are all pieces of the same puzzle.
