Book Description
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.

Book Description
Based on the award-winning PBS documentary series, Ring of Fire is this first-person account of the adventures of two English brothers as they explore the astonishingly rich cultures of the Indonesian archipelago. Their fascinating odyssey began in 1972 with a 2,500-mile voyage through the fabled Spice Islands, in search of the Greater Bird of Paradise. A decade of further exploration followed, during which the brothers lived among the Asmat cannibals of Papua and the healers of Bali, came face-to-face with the man-eating dragons of Komodo, and encountered the elusive dream wanderers of Borneo. Amid impenetrable rain forests, erupting volcanoes and startling natural beauty, the brothers have captured on film and in words the story of one of the most captivating and intriguing explorations ever made.

The Retina and Circadian Rhythms PDF Author: Gianluca Tosini

ISBN: 1461496136

Languages : en
Pages : 245

Book Description
Daily rhythms are a ubiquitous feature of living systems. Generally, these rhythms are not just passive consequences of cyclic fluctuations in the environment, but instead originate within the organism. In mammals, including humans, the master pacemaker controlling 24-hour rhythms is localized in the suprachiasmatic nuclei of the hypothalamus (SCN). This circadian clock is responsible for the temporal organization of a wide variety of functions, ranging from sleep and food intake, to physiological measures such as body temperature, heart rate and hormone release. Moreover, accumulating evidence suggests that dysfunction of the circadian rhythms due to genetic mutations or environmental factors (i.e., jet-lag or shift work) contribute to the development of many pathologies, including sleep disorders, mood and affective disorders such as major depression, bipolar disorder and schizophrenia, as well as the risk of metabolic and cardiovascular disorders.

The Rhythms Of Life

Book Description
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.

Rhythms for Life

Book Description
Spiritual transformation is not a one-size-fits-all journey—we each need distinct spiritual rhythms that align us with our unique identity and calling in Christ. In this practical book Alastair Sterne shows how we can craft a life of more intentionality, offering fourfold rhythms that point us upward to God, inward to self, withward in community, and outward in mission.

Biological Rhythms and Medicine

Biological Rhythms and Medicine PDF Author: A. Reinberg
Publisher: Springer Science & Business Media
ISBN: 1461394961
Category : Medical
Languages : en
Pages : 313

Book Description
During the past decade many review papers and books have been devoted to descriptions and analyses of biological rhythms (chronobiology) in plants and animals. These contributed greatly to demonstrating the impor tance of bioperiodicities in living beings in general. However, the practi cal aspects of chronobiology with regard to human health and improving the treatment of disease have not yet been a major focus of publication. One of our aims is to establish the relevance of biological rhythms to the practice of medicine. Another is to organize and convey in a simple fashion information pertinent to health- and life-science professionals so that students, researchers, and practitioners can achieve a clear and pre cise understanding of chronobiology. We have limited scientific jargon to unavoidable basic and well-defined terms and we have emphasized illus trative examples of facts and concepts rather than theories or hypotheti cal mechanisms. This volume is divided into seven chapters, each of which is compre hensive in its treatment and includes an extensive bibliography. The book is organized to serve as a textbook and/or reference handbook of modem applied chronobiology. Chapter 1 describes the historical development of chronobiology and reviews why, when, and how major concepts were introduced, accepted, and transformed.

Book Description
Tush, my good lord, this superficial tale Is but a preface of her worthy praise; King Henry the Sixth: Part I, Act V, Sc. 5 This volume is the direct result of a NATO. Advanced Study Institute (ASI) of the same title, held at Bishop's University, Lennoxville, Quebec, Canada in August 1991. All the major presentations had been commissioned, so to speak, during the organisational phase. This was done with the view of not only having a structured ASI, whIch is expected to be a high-level tutorial activity, but also the ensuing volume. As will be indicated in the general introduction, there have been a couple of meetings and publications dealing with rhythms in fishes in the past twenty years. However, as in other disciplines, there has been substantial progress in this field also. Further, I wished to cover almost all aspects and come out with a volme which will be as complete as possible. Of course, this failed to materialise. In spite of starting the arrangements two years before the event, several lecturers were not able to attend due to a number of reasons. Some could be replaced while others could not Taking into account their individual specialties, I asked about twenty active workers in the field to provide provoking overviews, not simply reviews of their own work. Also, this being a NATO.
