Coenzyme Q

This book offers a comprehensive exploration of research on the essential relationship of the coenzyme Q10 and the process of aging in living organisms. CoQ10 is an important factor in two main aspects of cell physiology: bioenergetics and antioxidant protection. While primary deficiency of CoQ10 is associated with severe and lethal disease, secondary deficiency can be associated with the progression of mitochondrial dysfunction linked to the lessening of biological activities during aging. The book is organized in four sections. The first offers an overview of the function of CoQ10, highlighting the two main functions of CoQ10 in cells: its essential role as electron transport chain member in mitochondria, and the protection of cell membranes against oxidation as one of the main endogenous-synthesized antioxidants. The second section covers research on Coenzyme 10. Topics include studies involving invertebrate models, mammal studies and the influence of CoQ on longevity. Also covered is research involving the role of CoQ in senescence-accelerated mice. Section three examines the effects of reduced CoQ in human aging, as evident in mitochondrial dysfunction, metabolic syndrome, neurodegenerative disorders, immunosenescence and fertility and reproduction. The final section, Prolongevity effectors and Coenzyme Q, explores research into slowing or stopping the aging process. Coverage includes strategies including calorie restriction, and modulation of CoQ10 levels by induction of synthesis or by supplementation. Coenzyme Q in Aging benefits a broad readership of researchers, clinicians, educators and students interested in the biochemical and physiological effects of coenzyme Q and the importance of this molecule in aging process.

This book provides an overview of statin-associated muscle symptoms (SAMS) from clinical presentation to treatment and possible metabolic causes. It examines the risk factors, presentations, diagnosis and differential diagnosis, clinical management, and financial costs of SAMS. The book also highlights patients’ perspectives on SAMS such as the psychosocial, emotional, and societal factors influencing their perceptions and experiences. Finally, the book presents the results of observational and clinical trials on the prevalence of SAMS, clinical trials for treatments, and potential future research approaches for improving the understanding and treatment of SAMS. A key addition to the Contemporary Cardiology series, Statin-Associated Muscle Symptoms is an essential resource for physicians, medical students, residents, fellows, and allied health professionals in cardiology, endocrinology, pharmacotherapy, primary care, and health promotion and disease prevention.

Since its discovery in 1957, Coenzyme Q has piqued the interest of scientists from a wide range of disciplines because of its bioenergetics, vitamin-like behavior, and interactions with antioxidant vitamins E and C. Coenzyme Q: Molecular Mechanisms in Health and Disease is a comprehensive treatise on this often-studied coenzyme. International exper

There is a growing interest in coenzyme Q10 (CoQ10) and its involvement in many aspects of daily living including physical and mental health, energy, aging, stress, skin care and exercise. This book aims to highlight our current understanding of CoQ10 in each of these areas by presenting a selection of topics that clearly illustrates its role in both health and disease. Each chapter provides a specialist's insight into the subject whilst being written in a manner that is accessible to the non-CoQ10 expert. Is CoQ10 deficiency a contributor to heart disease, depression or migraines? Can taking CoQ10 supplements reduce symptoms of menopause, increase exercise tolerance or make our skin look younger? What is known about the genetics of CoQ10 biosynthesis? These are just some of the questions addressed in this book: which of them is fact and which is fiction?

Coenzyme Q10: Uses, Health Effects and Role in Disease reviews the current knowledge and evidence of the potential clinical applications of Coenzyme Q10 (CoQ10). CoQ10 is a lipophilic molecule composed by a bezonquinone ring conjugated to a ten-carbon isoprenoid side chain. It exists in two molecular forms, ubiquinone and ubiquinol, which are the basis for its antioxidant properties. CoQ10 also plays an essential role in cellular metabolism to produce ATP, which provides energy for muscle contraction and other vital cellular functions. Most of the ATP production occurs in the inner mitochondrial membrane, where coenzyme Q is found. The authors review the protective effects of CoQ10 on intense physical exercise, reducing muscle damage and improving physical performance. Evidence of secondary CoQ10 deficiency in disease and in pharmacotherapy is discussed, highlighting putative mechanisms to account for this deficit together with examples of therapeutic intervention. Secondary CoQ10 deficiencies are important to identify as clinical benefit can be elicited following treatment with CoQ10 or its associated analogues.

The use of antioxidants in sports is controversial due to existing evidence that they both support and hinder athletic performance. Antioxidants in Sport Nutrition covers antioxidant use in the athlete ́s basic nutrition and discusses the controversies surrounding the usefulness of antioxidant supplementation. The book also stresses how antioxidants may affect immunity, health, and exercise performance. The book contains scientifically based chapters explaining the basic mechanisms of exercise-induced oxidative damage. Also covered are methodological approaches to assess the effectiveness of antioxidant treatment. Biomarkers are discussed as a method to estimate the bioefficacy of dietary/supplemental antioxidants in sports. This book is useful for sport nutrition scientists, physicians, exercise physiologists, product developers, sport practitioners, coaches, top athletes, and recreational athletes. In it, they will find objective information and practical guidance.
