Download or read book Ultradian Rhythms in Life Processes written by David Lloyd and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Profound progress has been made in the fields of chronobiology and psychobiology within the past decade, in theory, experiment and clinical application. This volume integrates these new developments on all levels from the molecular, genetic and cellular to the psycho social processes of everyday life. We present a balanced variety of research from workers around the globe, who discuss the funda mental significance of their approach for a new understanding of the central role of ultradian rhythms in the self-organizing and adaptive dynamics of all life processes. The years since the publication of Ultra dian rhythms in physiology and behavior by Schultz and Lavie in 1985 have seen a burgeoning realization of the ubiquity and importance of ultradian rhythms within and between every level of the psychobiological hierarchy. The experimental evidence lies scattered through a disparate litera ture, and this volume attempts, albeit in a highly selective manner, to bring together some of the different strands. The editors are very conscious of the omission of many important current aspects; e.g. we have not included any of the fascinating and indeed long and well-established experiments with plants (Bunning 1971, 1977; Guillaume and Koukkari 1987; Millet et al. 1988; 10hnsson et al. 1990) that are widely regarded as having initiated the whole field of chronobiology (De Mairan 1729). Neither have we reviewed recent developments on glycolytic oscillations, since a great deal of the seminal work was already completed by 1973 (Chance et al. 1973).

This book was released on 2008-08-27 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: 5. 1. 1 Biological Rhythms and Clocks From an evolutionary perspective, the adaptation of an organism’s behavior to its environment has depended on one of life’s fundamental traits: biological rhythm generation. In virtually all light-sensitive organisms from cyanobacteria to humans, biological clocks adapt cyclic physiology to geophysical time with time-keeping properties in the circadian (24 h), ultradian (24 h) domains (Edmunds, 1988; Lloyd, 1998; Lloyd et al. , 2001; Lloyd and Murray, 2006; Lloyd, 2007; Pittendrigh, 1993; Sweeney and Hastings, 1960) By definition, all rhythms exhibit regular periodicities since they constitute a mechanism of timing. Timing exerted by oscillatory mechanisms are found throughout the biological world and their periods span a wide range from milliseconds, as in the action potential of n- rons and the myocytes, to the slow evolutionary changes that require thousands of generations. In this context, to understand the synchronization of a population of coupled oscillators is an important problem for the dynamics of physiology in living systems (Aon et al. , 2007a, b; Kuramoto, 1984; Strogatz, 2003; Winfree, 1967). Circadian rhythms, the most intensively studied, are devoted to measuring daily 24 h cycles. A variety of physiological processes in a wide range of eukaryotic organisms display circadian rhythmicity which is characterized by the following major properties (Anderson et al. , 1985; Edmunds, 1988): (i) stable, autonomous (self-sustaining) oscillations having a free-running period under constant envir- mental conditions of ca.

Available in PDF, EPUB and Kindle. Book excerpt: Introducing a radical approach to wellness: This self-help guide rejects ‘one-size-fits-all’ dieting and health advice to offer practical strategies and tools for getting healthy—your way. What kind of society makes being healthy and happy so difficult that only a single-digit percentage of the population can hope to pull it off? The answer: A sick society. And within a sick society—one where illness, anxiety, and depression are the prevailing norms—what does it mean to be one of the few people to beat those unhealthy odds? It means bucking a lot of your society’s norms and rejecting a lot of its conventional health prescriptions. It also means acknowledging a disturbing truth: If you aren’t breaking the rules, you’re probably breaking yourself. That’s the simple, provocative philosophy behind The Healthy Deviant, one seasoned health journalist’s quest to reframe healthy choices as a positive form of social rebellion. Combining hand-drawn infographics and statistics with insights from sociology, psychology, evolutionary biology, functional medicine, and the school of hard knocks, this category-defying book rejects the idea that diet and exercise alone can save us—or are even the best places to start. Gerasimo’s 14-day Healthy-Deviant Adventure Program presents a series of powerful perspective shifts and simple daily practices—plus illustrations, infographics, worksheets, reminders, and progress tracking tools—that put you firmly back in charge of your own wellbeing. Part manifesto, part whispered wake-up call, The Healthy Deviant is a modern-day survival guide for being a healthy person in an unhealthy world. Starting now.

Available in PDF, EPUB and Kindle. Book excerpt: Recent years have seen spectacular advances in the field of circadian biology. These have attracted the interest of researchers in many fields, including endocrinology, neurosciences, cancer, and behavior. By integrating a circadian view within the fields of endocrinology and metabolism, researchers will be able to reveal many, yet-unsuspected aspects of how organisms cope with changes in the environment and subsequent control of homeostasis. This field is opening new avenues in our understanding of metabolism and endocrinology. A panel of the most distinguished investigators in the field gathered together to discuss the present state and the future of the field. The editors trust that this volume will be of use to those colleagues who will be picking up the challenge to unravel how the circadian clock can be targeted for the future development of specific pharmacological strategies toward a number of pathologies.

Book excerpt: Popular science at its most exciting: the breaking new world of chronobiology - understanding the rhythm of life in humans and all plants and animals. The entire natural world is full of rhythms. The early bird catches the worm -and migrates to an internal calendar. Dormice hibernate away the winter. Plants open and close their flowers at the same hour each day. Bees search out nectar-rich flowers day after day. There are cicadas that can breed for only two weeks every 17 years. And in humans: why are people who work anti-social shifts more illness prone and die younger? What is jet-lag and can anything help? Why do teenagers refuse to get up in the morning, and are the rest of us really 'larks' or 'owls'? Why are most people born (and die) between 3am-5am? And should patients be given medicines (and operations) at set times of day, because the body reacts so differently in the morning, evening and at night? The answers lie in our biological clocks the mechanisms which give order to all living things. They impose a structure that enables us to change our behaviour in relation to the time of day, month or year. They are reset at sunrise and sunset each day to link astronomical time with an organism's internal time.

Download or read book Military Strategies for Sustainment of Nutrition and Immune Function in the Field written by Institute of Medicine and published by National Academies Press. This book was released on 1999-05-13 with total page 722 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every aspect of immune function and host defense is dependent upon a proper supply and balance of nutrients. Severe malnutrition can cause significant alteration in immune response, but even subclinical deficits may be associated with an impaired immune response, and an increased risk of infection. Infectious diseases have accounted for more off-duty days during major wars than combat wounds or nonbattle injuries. Combined stressors may reduce the normal ability of soldiers to resist pathogens, increase their susceptibility to biological warfare agents, and reduce the effectiveness of vaccines intended to protect them. There is also a concern with the inappropriate use of dietary supplements. This book, one of a series, examines the impact of various types of stressors and the role of specific dietary nutrients in maintaining immune function of military personnel in the field. It reviews the impact of compromised nutrition status on immune function; the interaction of health, exercise, and stress (both physical and psychological) in immune function; and the role of nutritional supplements and newer biotechnology methods reported to enhance immune function. The first part of the book contains the committee's workshop summary and evaluation of ongoing research by Army scientists on immune status in special forces troops, responses to the Army's questions, conclusions, and recommendations. The rest of the book contains papers contributed by workshop speakers, grouped under such broad topics as an introduction to what is known about immune function, the assessment of immune function, the effect of nutrition, and the relation between the many and varied stresses encountered by military personnel and their effect on health.
Download or read book Circannual Rhythms written by Eberhard Gwinner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: In addition to the more or less static properties of the environ ment, plants and animals must cope with its temporal variations. Among the most conspicuous temporal changes to which organisms are exposed are periodic phenomena generated by the rotation of the earth about its axis, its revolution around the sun, and the more complex movements of the moon in relation to both sun and earth. The first two of these astronomical cycles are basic to the familiar daily and annual rhythms, respectively, in the environment. The third generates somewhat more complex cycles, such as those in moonlight and variations in tides. These environmental cycles have provided challenges and opportunities for organisms to adjust their physiology and behavior to them. Indeed, the predictability inherent to these periodic processes has enabled organisms to evolve innate endogenous rhythmic programs that match the environmental cycles and allow, in a variety of different ways, adjustment of biological activities to the cycles of environmental changes. The endogenous nature of rhythmicity was first clearly recognized in the 1930's in daily periodicities, the most widely distributed and best investigated class of biological rhythms of this type. In the 1950's, demonstrations of endogenous tidal and lunar rhythms, which occur in some littoral and marine organisms, ensued. Another decade passed before endogenous annual periodicities were first demonstrated unambiguously.
