Available in PDF, EPUB and Kindle. Book excerpt: Proceedings are presented of a symposium on Circadian Rhythms in Nonhuman Primates at the Second International Congress of Primatoloty, Atlanta, Georgia, July 2, 1968. It contains papers on both behavioral and physiological rhythms in which the chimpanzee, baboon, and nemistrina, rhesus, and cebus monkeys were subjects. As such it represents the first attempt to consolidate the current research in this area. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Chronobiology is the study of adaptations evolved at all levels of organization by living organisms to cope with regular geophysical cycles in the environment. The Earth s rotation originates alternation of light and darkness with a 24-h period; this signal allowed primordial organisms to keep track of time, adjust their internal temporal order, and anticipate external time. This capability fostered the development in living matter of endogenous temporal organization of cellular process over an approximately 24-h period. The cellular machinery that generates this ability is known as the biological clock, and its outputs as circadian rhythms. Such clocks can be found in nearly all organisms, from simple bacteria to insects, mammals, and of course, humans. The selective advantage conferred to all organisms by the biological clock comprises coordination of molecular, physiological, and behavioral processes, so as to ensure its occurrence during the daily cycle s optimal time. When organisms are maintained in an environment with strong time signals (zeitgebers) such as the light-dark cycle, each of their circadian rhythms establishes a stable relationship with each other and with the external cycle, and becomes an entrained system. Different species and different individuals within each species are coupled with their own typical phases to the natural 24-h cycle. Thus, time is embedded in our genes, and circadian clocks have emerged several times during evolution as a result of convergence to meet a common need. And although key proteins are not conserved, all clocks known to date in eukaryotes involve transcriptional-translational feedback loops. Over the last decades, chronobiology has expanded enormously, is emerging independently in many fields, and it is one of the most interdisciplinary fields in biology. While it has not been easy to understand how a biological clock works in an organism, research with different models from single-cell organisms to complex multicellular plants and animals have provided us insight concerning the ticking of the clock. Identification of circadian rhythms in biochemical and behavioral parameters in different unicellular organisms, localization of different oscillators in combination with behavioral outputs markers by neurobiological techniques in insects and mammals, as well as molecular genetics that has led to identification and cloning of clock genes in several species including humans have rendered chronobiology a diverse and dynamic discipline, with not only biological relevance but also important social and medical implications. Our goal in editing this book was to provide a comparative view of our current knowledge regarding circadian rhythms and clocks at different phylogenetic levels. The authors contributing to this volume review both circadian molecules and mechanisms in representative groups ranging from simple organisms as unicells to complex ones such as invertebrates and non-mammal and mammal vertebrates. The book reflects and is a token of different approaches to the field, such as regulation molecules and their biochemical pathways involved in either circadian or exogenous aspects of the rhythmic process and its regulation in photoautotrophic unicells and the neurobiological and molecular bases of circadian oscillators in some invertebrates and vertebrates. A number of works are focused in the importance of environmental, social, and nutrient temporal signals as synchronizing agents in insects and in different vertebrate models. These reviews are not only centered on the adult organism at the integrative level, but also provide an ontogenetic view at behavioral, physiological, and molecular levels. Furthermore, they supply evidence on several organs as potential sources of circadian signaling for different vertebrate groups, which indicates multioscillatory circadian systems similar to those proposed for some invertebrates. In Chapter 1, Rüdiger Hardeland revises the importance of tryptophan metabolic pathways in two unicells, Euglena gracilis, and the dinoflagellate, Lingulodinium polyedrum. Barbara-Ann Battelle, in Chapter 2, reviews and describes current knowledge of the circadian system of a Chelicerata, Limulus polyphemus, visual inputs into the central clock, and efferent pathways of the clock to the eyes, in addition to the molecular mechanisms underlying these processes. In Chapter 3, María Elena Durán-Lizárraga et al. review the role of different crustacean neuropeptides in the regulation of several physiological processes, such as those proposed as controlled by the circadian system of decapoda, particularly in crayfish. Claudio R. Lazzari and Teresita C. Insausti examine, in Chapter 4, the importance of circadian rhythms from insect s populations, closely associated with the history of chronobiology and the Pittendrigh pioneering work. Continuing on insects, the concept of the superorganism and the interaction of rhythms at different frequencies in different cohorts of individuals forming a colony is presented in Chapter 5 by Mirian David-Marques and Cintia Etsuko-Yamashita. In dealing with vertebrates, Raquel Carvalho and Luiz Menna-Barreto in Chapter 6 address fish from the phenomenology of circadian rhythms to the description of the underlying multioscillatory system, finally reviewing its ecological and evolutionary relevance of these species as a model. The following chapter (7) by Carolina Escobar et al. offers an integrative view of the so-called food-entrained oscillator in rodents. Then, in Chapter 8 Ivette Caldelas and colleagues provide us with an ontogenetic approach to non-visual entrainment of the circadian system, an alternative view of the food-entrained oscillator, using as a natural model the newborn rabbit. Still in the area of restricted food availability as an entraining signal, in Chapter 9 Adrián Báez-Ruíz et al. provide yet another perspective of this phenomenon, which stresses the role of liver physiology and biochemistry in the regulation of food ingestion and hepatic circadian rhythmicity. Finally, in Chapter 10 Raúl Aguilar-Roblero and colleagues review the role of the rodent suprachiasmatic nuclei as a biological clock for the mammalian circadian system, with emphasis on molecular and cellular aspects involved in the first steps of coding biological time into a signal readable by its neuronal targets. We have attempted to provide a panoramic perspective of the multiple approaches for addressing the study of the circadian system in different organisms. Selection of contributions included certain aspects of circadian rhythms not easily found in other reviews. We are indebted to the enthusiastic response of the entire group of contributors, all distinguished professors from universities from different countries, in achieving publication of this volume. We hope readers will find the text useful and that it will perhaps further promote their interest in this area of biology.

This book was released on 2014-10-31 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Well known experts in the field of Chronobiology from around the world, provide an integrative view of the state of the art of circadian biology. At present, genetic and epigenetic interaction of regulatory pathways among circadian oscillators, metabolic networks, cellular differentiation and neuronal communication are subject of intense scrutiny. The book is organized in three sections: The first includes selected examples of the circadian systems of crustaceans, insects, fish, birds and mammals. The second is a detailed view of the physiological mechanisms underlying the circadian clocks in mammals. Finally, in the third section some examples of the relevance of circadian biology and circadian misalignment to health and disease are provided including nutrition and metabolism, obesity, cancer, cardiovascular and pulmonary diseases, Huntington and affective diseases. This section concludes with a brief review on gene therapy and its potential use as a therapeutic tool to correct “clock genes” pathologies. This book is aimed at all those interested in contemporary aspects of physiology, biochemistry and molecular biology applied to the study and characterization of timing systems.. It could be used as an initial approach to this field, but it also provides updated information for those already familiar with the fascinating field of Chronobiology.
