This book gives a complete overview of current developments on the green synthesis and extraction of nano-emulsions for numerous uses in food, agriculture, biomedical, and cosmetics sectors. In the food and agriculture section, the book demonstrates the use of nano-emulsions to deliver nutraceuticals, coloring, and flavoring agents, in the development of biodegradable coating, improving the quality of packing films and enhancing the shelf life and nutritional value of foods. It also shows that nano-emulsions are very good for pesticides formulation where it enhances the solubility of poorly water-soluble pesticides, resulting in increased pesticide bioactivity compared to conventional pesticides. In the biomedicine applications section, the chapters show that nano-emulsion can dissolve hydrophobic drugs and is used as a drug delivery system for many cancers treatment such as lung cancer, breast cancer, prostate cancer, liver, and gastric cancer. Also, nano-emulsions are an excellent candidate for encapsulating drugs or imaging probes for targeted delivery and immunotherapy. This book caters to scientists, researchers, and students interested in nanotechnology, nanomedicine, environmental science, plant science, agriculture, chemistry, biotechnology, pharmacognosy, pharmaceuticals, industrial chemistry, and many other interdisciplinary subjects.

This book provides concrete scientific basis that we can conceive the possibility of modifying or even completely canceling aging process, despite the fact that aging is commonly regarded as the result of the overall effects of many uncontrollable degenerative phenomena. The authors illustrate in detail the mechanisms by which cells and the whole organism age. Actions by which it is possible, or will be possible within a limited time, to operate for modifying aging are also debated.The discussion is conducted within the frame and the concepts of evolutionary medicine, which is also indispensable for distinguishing between the manifestations of aging and: (i) diseases that worsen with age, and (ii) acceleration of normal aging rates, caused by unhealthy lifestyle habits and other avoidable factors. The book also discusses the impact of aging on overall mortality and the strange situation that, according to official statistics, aging does not exist as cause of death.This book is a turning point between a gerontology and geriatrics conceived as the study and vain treatment of an incurable condition and one in which these disciplines examine the how and why of a physiological phenomenon that can be modified up to a possible total control. This means transforming the medical prevention and treatment of physiological aging from the greatest failure to the greatest success of medicine.

Modern humanity with some 5,000 years of recorded history has been experiencing growing pains, with no end in sight. It is high time for humanity to grow up and to transcend itself by embracing transhumanism. Transhumanism offers the most inclusive ideology for all ethnicities and races, the religious and the atheists, conservatives and liberals, the young and the old regardless of socioeconomic status, gender identity, or any other individual qualities. This book expounds on contemporary views and practical advice from more than 70 transhumanists. Astronaut Neil Armstrong said on the Apollo 11 moon landing in 1969, “One small step for a man, one giant leap for mankind.” Transhumanism is the next logical step in the evolution of humankind, and it is the existential solution to the long-term survival of the human race.

This volume provides comprehensive coverage of the current knowledge of the physiology of the endocrine system and hormone synthesis and release, transport, and action at the molecular and cellular levels. It presents essential as well as in-depth information of value to both medical students and specialists in Endocrinology, Gynecology, Pediatrics, and Internal Medicine. Although it is well established that the endocrine system regulates essential functions involved in growth, reproduction, and homeostasis, it is increasingly being recognized that this complex regulatory system comprises not only hormones secreted by the classic endocrine glands but also hormones and regulatory factors produced by many organs, and involves extensive crosstalk with the neural and immune system. At the same time, our knowledge of the molecular basis of hormone action has greatly improved. Understanding this complexity of endocrine physiology is crucial to prevent endocrine disorders, to improve the sensitivity of our diagnostic tools, and to provide the rationale for pharmacological, immunological, or genetic interventions. It is such understanding that this book is designed to foster.

This textbook presents concise chapters written by internationally respected experts on various important aspects of cancer-associated metabolism, offering a comprehensive overview of the central features of this exciting research field. The discovery that tumor cells display characteristic alterations of metabolic pathways has significantly changed our understanding of cancer: while the first description of tumor-specific changes in cellular energetics was published more than 90 years ago, the causal significance of this observation for the pathogenesis of cancer was only discovered in the post-genome era. The first 10 years of the twenty-first century were characterized by rapid advances in our grasp of the functional role of cancer-specific metabolism as well as the underlying molecular pathways. Various unanticipated interrelations between metabolic alterations and cancer-driving pathways were identified and currently await translation into diagnostic and therapeutic applications.Yet the speed, quantity, and complexity of these new discoveries make it difficult for researchers to keep up to date with the latest developments, an issue this book helps to remedy.

Aging represents a physiological and per se non-pathological and multifactorial process involving a set of key genes and mechanisms being triggered by different endogenous and exogenous factors. Since aging is a major risk factor in connection with a variety of human disorders, it is increasingly becoming a central topic in biochemical and medical research. The plethora of theories on aging – some of which have been discussed for decades – are neither isolated nor contradictory but instead can be connected in a network of pathways and processes at the cellular and molecular levels. This book summarizes the most prominent and important approaches, focusing on telomeres, DNA damage and oxidative stress as well as on the possible role of nutrition, the interplay between genes and environment (epigenetics) and intracellular protein homeostasis and introduces some genes that have actually extended life spans in animal models. Linking these different determinants of aging with disease, this volume aims to reveal their multiple interdependencies. We see that there is no single “perfect” theory of aging and that instead it is possible to define what the authors call the molecular aging matrix of the cell. A better knowledge of its key mechanisms and the mutual connections between its components will lead to a better understanding of age-associated disorders such as Alzheimer's disease.

This wide-ranging and accessible book serves as a fascinating guide to the strategies and concepts that help us understand the boundaries between physics, on the one hand, and sociology, economics, and biology on the other. From cooperation and criticality to flock dynamics and fractals, the author addresses many of the topics belonging to the broad theme of complexity. He chooses excellent examples (requiring no prior mathematical knowledge) to illuminate these ideas and their implications. The lively style and clear description of the relevant models will appeal both to novices and those with an existing knowledge of the field.

This volume includes contributions by the leading experts in the field of yeast aging. Budding yeast (Saccharomyces cerevisiae) and other fungal organisms provide models for aging research that are relevant to organismic aging and to the aging processes occurring in the human body. Replicative aging, in which only the mother cell ages while the daughter cell resets the clock to zero is a model for the aging of stem cell populations in humans, while chronological aging (measured by survival in stationary phase) is a model for the aging processes in postmitotic cells (for instance, neurons of the brain). Most mechanisms of aging are studied in yeast. Among them, this book discusses: mitochondrial theories of aging, emphasizing oxidative stress and retrograde responses; the role of autophagy and mitophagy; the relationship of apoptosis to aging processes; the role of asymmetric segregation of damage in replicative aging; the role of replication stress; and the role of the cytoskeleton in aging. Modern methods of yeast genetics and genomics are described that can be used to search for aging-specific functions in a genome-wide unbiased fashion. The similarities in the pathology of senescence (studied in yeast) and of cancer cells, including genome instability, are examined.

Food or calorie restriction has been shown in many short-lived animals and the rhesus monkey to prolong life-span. Life-long nutrition studies are not possible in humans because of their long survival. Studies over two to six years in healthy adult humans have, however, shown that a 20% reduction in food or calorie intake slows many indices of normal and disease-related aging. Thus, it is widely believed that long-term reduction in calorie or food intake will delay the onset of age-related diseases such as heart disease, diabetes and cancer, and so prolong life. Over the last 20 or more years there has been a progressive rise in food intake in many countries of the world, accompanied by a rising incidence of obesity. Thus our increasing food and calorie intake has been linked to the rising incidence of cardiovascular disease and diabetes in early adult life. It is accepted that overeating, accompanied by reduced physical exercise, will lead to more age-related diseases and shortening of life-span. The answer is to reduce our calorie intake, improve our diet, and exercise more. But calorie restriction is extremely difficult to maintain for long periods. How then can we solve this problem? Edited by a team of highly distinguished academics, this book provides the latest information on the beneficial effects of calorie restriction on health and life-span. This book brings us closer to an understanding at the molecular, cellular and whole organism level of the way forward.

Social differences in health and mortality constitute a persistent finding in epidemiological, demographic, and sociological research. This topic is increasingly discussed in the political debate and is among the most urgent public health issues. However, it is still unknown if socioeconomic mortality differences increase or decrease with age. This book provides a comprehensive, thoughtful and critical discussion of all aspects involved in the relationship between socioeconomic status, health and mortality. In a well-written language, it synthesizes the sociological theory of social inequality and an empirical study of mortality differences that has been performed at the Max Planck Institute for Demographic Research (Rostock, Germany). The best available datasets from Denmark and the USA, as two very different countries, are used to analyze the age pattern of social mortality differences, the Danish register data covering the whole Danish population between 1980 and 2002. This study is the most comprehensive analysis of socioeconomic mortality differences in the literature, in terms of data quantity, quality, and the statistical method of event-history modeling. It makes important new theoretical and empirical contributions. With a new method it also addresses the question whether the measurement of social mortality differences in old age so far has been biased by mortality selection due to unobserved heterogeneity.'This book signifies an important step forward in theory, empirical data analysis and methodology and an advancement for many disciplines involved in the subject of socioeconomic differences in old age mortality'. Prof. Dr. Gabriele Doblhammer, Max Planck Institute for Demographic Research, Rostock, Germany

Seasonal fluctuations in mortality are a persistent phenomenon across populations. In Western countries of the Northern hemisphere, mortality is typically larger in winter than in summer which is attributed to the detrimental effects of cold to health. This does, however, not explain why in colder countries the differences between winter and summer mortality are smaller than in countries with warm or moderate climate. This book, therefore, investigates whether sociodemographic and socioeconomic factors play a role as important for seasonal mortality as they do for mortality in general. Using modern statistical methods, the book shows, for example for the United States, that the fluctuations between winter and summer mortality are smaller the more years someone has spent in school.
