Book Description
This excellent book describes the roles of the suprachiasmatic nucleus (SCN) of the hypothalamus as a regulatory center of homeostatic mechanism and a circadian oscillator in mammals, including humans. The authors emphasize two important points based on their findings: 1) SCN plays a critical role in central regulation of energy metabolism through which a constant supply of glucose to the central nervous system (CNS) is well maintained; and 2) neurons responsible for the regulation of energy metabolism are located in the ventrolateral part of the SCN and receive retinal neural inputs through both the retinohypothalamic tract and the geniculohypothalamic tract. The authors then discuss the evolutionary importance of these points to the survival of mammals on earth. Other topics examined include the involvement of light in the regulation of neural activity of the autonomic nervous system through the retina and SCN, in addition to the relation of the SCN with regulations of other autonomic nerve functions, such as blood pressure and body temperature. Central Regulation of Energy Metabolism with Special Reference to Circadian Rhythm is important reading for researchers and students in neuroendocrinologists, neurobiologists, biochemists, endocrinologists, physiologists, chronobiologists, psychologists, pharmacologists, and others interested in the topic.

Book Description
One of the major breakthroughs of the last decade in the understanding of energy homeostasis is the identification of a reciprocal control between circadian rhythmicity and cellular metabolism. Circadian rhythmicity is a fundamental endogenous process of almost every organism living on Earth. For instance, the alternation of hunger and satiety is not continuous over 24 h, but is instead structured in time along the light/dark cycle. In mammals, the temporal organization of metabolism, physiology and behavior around 24 h is controlled by a network of multiple cellular clocks, synchronized via neuronal and hormonal signals by a master clock located in the suprachiasmatic nuclei of the hypothalamus. This central circadian conductor in the brain is mainly reset by ambient light perceived by the retina, while secondary circadian clocks in other brain areas and peripheral organs can be reset by meal timing. Chronic disruption of circadian rhythms, as seen in human shift-workers (up to 20% of the active population), has been associated with the development of a number of adverse mental and metabolic conditions. Understanding of the functional links between circadian desynchronization and overall health in animal models and humans, however, is still scarce. Interactions between circadian clocks and metabolism can occur at different levels: the molecular clockwork, internal synchronization via neuro-hormonal signals, or external synchronization via photic or feeding cues. This Research Topic comprises a number of reviews as well as research and methods articles that feature recent advancements in the mechanisms linking circadian clocks with energy metabolism, and the pathophysiological implications of these interactions for metabolic health.

Book Description
With the invitation to edit this volume, I wanted to take the opportunity to assemble reviews on different aspects of circadian clocks and rhythms. Although most c- tributions in this volume focus on mammalian circadian clocks, the historical int- duction and comparative clocks section illustrate the importance of various other organisms in deciphering the mechanisms and principles of circadian biology. Circadian rhythms have been studied for centuries, but only recently, a mole- lar understanding of this process has emerged. This has taken research on circadian clocks from mystic phenomenology to a mechanistic level; chains of molecular events can describe phenomena with remarkable accuracy. Nevertheless, current models of the functioning of circadian clocks are still rudimentary. This is not due to the faultiness of discovered mechanisms, but due to the lack of undiscovered processes involved in contributing to circadian rhythmicity. We know for example, that the general circadian mechanism is not regulated equally in all tissues of m- mals. Hence, a lot still needs to be discovered to get a full understanding of cir- dian rhythms at the systems level. In this respect, technology has advanced at high speed in the last years and provided us with data illustrating the sheer complexity of regulation of physiological processes in organisms. To handle this information, computer aided integration of the results is of utmost importance in order to d- cover novel concepts that ultimately need to be tested experimentally.

Book Description
Cushing ́s syndrome is a rare disorder that is associated with many co-morbidities such as systemic hypertension, diabetes, osteoporosis, impaired immune function, and psychiatric disease, all of which severely reduce quality of life and life expectancy. This book reviews the role of cortisol in the human body, focusing on the effects of excess cortisol due to Cushing’s syndrome as well as the role of the HPA axis in metabolism, inflammation, and neuropsychiatric function. The volume will cover basic mechanistic data, clinical outcomes data, and novel therapies. Also discussed are everything from abnormalities of the HPA axis, to the role of the HPA axis in the development of neuropsychiatric disorders and metabolic disorders, to new definitions of Cushing’s remission and recurrence. The Hypothalamic Pituitary Adrenal Axis in Health and Disease will provide a comprehensive and multi-disciplinary review of the pathophysiology and outcomes of excess cortisol in the human body and brain as well as the role of the HPA axis in other disease states.

Book Description
What's new in antidepressant research? Despite the availability of antidepressants for over 40 years, a substantial proportion of depressed patients do not respond adequately to treatment. Failure to respond effectively to treatment contributes to physical ill-health and psychiatric morbidity, often resulting in premature death of the depressed patient. The purpose of this volume is to consider the possible reasons for the limitations of the currently available antidepressants, to examine the advances in our understanding of the psychopathology of depression and how such knowledge may assist in the discovery of new methods of treatment. Leading international experts in this field discuss the possible underlying reasons for depression and limitations of current antidepressants. Opportunities for novel therapeutic approaches to dysfunctional circadian rhythms and mood disorders as well as current status and future perspectives for optimizing antidepressant management of depression are reviewed. This publication illustrates the breadth of the latest research and is valuable reading for psychiatrists, neuroscientists and pharmacologists.

Book Description
Avoid, manage, and even reverse diabetes and prediabetes just by changing when—not what—you eat with this authoritative guide from the author of The Circadian Code. Today, one in ten Americans is diagnosed with type 2 diabetes, and one in three already has prediabetes. Prescription medications used to treat this chronic disease have unwanted side effects and at best, only manage the symptoms. What’s more, the restrictive dieting protocols used to manage diabetes are difficult to maintain over time. Yet the latest science shows that a simple approach that aligns your daily lifestyle—when you eat, sleep, and exercise—with your body’s inherent circadian rhythm can be just as effective. Best of all, following this program can enhance every other aspect of your health, from losing weight to boosting immunity. In The Circadian Diabetes Code, senior Salk Institute researcher and internationally-acclaimed author of The Circadian Code, Satchin Panda, Ph.D., shares his groundbreaking program. You will learn the best way to adopt intermittent fasting, the worldwide phenomenon that started in Dr. Panda’s lab, which has been used as an effective weight loss strategy for almost a decade. Now, you can use this same strategy to optimize your blood glucose response and naturally lower your risk for developing “the sinister friends of diabetes”: heart disease and obesity. The truth is, intermittent fasting is much easier that you think. You will learn how to: Identify your optimal eating zone Plan your meals according to your circadian rhythm Exercise at the right time to control blood glucose levels Get the best night’s sleep to reset your brain and body Optimally time medication, as needed And much more!
