This book was released on 2012-03 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essay from the year 2011 in the subject Biology - Cytology, grade: C, University of Glasgow (Institute of Cardiovascular and Medical Sciences), course: MRes Biomedical Sciences, language: English, abstract: The skeletal muscle is an integral part of our system. It not only acts as the storage reservoir of amino acids, but also serves as the site for protein synthesis and protein breakdown [36]. The rate of protein synthesis needs to exceed protein degradation to achieve muscle hypertrophy [18, 24]. The timing of protein intake, type and quantity play a significant role in achieving optimal outcomes when applied to resistance exercise [36]. Research has been going on since the past decade demonstrating the role of nutritional supplements like whey protein, soy, branched-chain amino acids (BCAAs, especially leucine) and creatine on protein synthesis before, during and after a bout of resistance exercise through careful investigations into intracellular signalling pathways like the mammalian target of rapamycin (mTOR) and its downstream targets-ribosomal protein S6 (kinase-1) and 4E binding protein (4E-BP1) [7, 18]. Intracellular signalling, amongst other variables, involves three essential components-abundant ATP in muscle for providing energy, insulin signalling and leucine (figure 1) [36, 37]. mTOR, regarded as the "key regulator" of translation comprises mTORC1 and mTORC2 [36]. mTORC1 plays a significant role in promoting muscular hypertrophy via phosphorylation of S6K1 and 4E-BP1 which prevent binding of the eukaryotic initiation factor (eIF) 4E to 4E-BP1 allowing a complex formation with eIF4G (eIF4E-eIF4G) thus enhancing protein synthesis [5, 34]. This report highlights how whey proteins and BCAA (leucine) affect muscle protein synthesis via intracellular signalling pathways thereby contributing significant effects on muscular hypertrophy.

Download or read book Handbook of diet nutrition and the skin written by Victor R. Preedy and published by Springer. This book was released on 2012-05-23 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies have clearly shown that optimal diet and nutrition can prevent skin disease. Moreover, novel nutritional components have been used experimentally to treat skin conditions. However, the clinical application of these nutrients awaits confirmation. It is thus up to health care professionals to present new knowledge in order to provide advice or treatments for skin problems. This handbook provides, in a single volume, comprehensive coverage of the relation between skin and diet and nutrition in its broadest sense. The Handbook of diet, nutrition and the skin consists of sections on general aspects of skin, nutrition and diet, micronutrients, nutraceuticals, cancer and specific skin conditions. Unique features of each chapter in this volume include relevant and useful 'key facts' which highlight interesting or important findings of the specific subjects and 'summary points' that are designed to abstract each chapter in take home messages. This handbook will be of interest to a wide range of readers, such as dermatologists, doctors, nurses and those interested in, or working within the area of skin health. This will of course also include nutritionists and dieticians, dermatologists, cosmetic scientists, health workers and practitioners, college and university lecturers and undergraduate and graduate students.

Download or read book The Role of Protein and Amino Acids in Sustaining and Enhancing Performance written by Institute of Medicine and published by National Academies Press. This book was released on 1999-09-15 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is a commonly held belief that athletes, particularly body builders, have greater requirements for dietary protein than sedentary individuals. However, the evidence in support of this contention is controversial. This book is the latest in a series of publications designed to inform both civilian and military scientists and personnel about issues related to nutrition and military service. Among the many other stressors they experience, soldiers face unique nutritional demands during combat. Of particular concern is the role that dietary protein might play in controlling muscle mass and strength, response to injury and infection, and cognitive performance. The first part of the book contains the committee's summary of the workshop, responses to the Army's questions, conclusions, and recommendations. The remainder of the book contains papers contributed by speakers at the workshop on such topics as, the effects of aging and hormones on regulation of muscle mass and function, alterations in protein metabolism due to the stress of injury or infection, the role of individual amino acids, the components of proteins, as neurotransmitters, hormones, and modulators of various physiological processes, and the efficacy and safety considerations associated with dietary supplements aimed at enhancing performance.

Download or read book Nutrition and Aging written by Irwin H. Rosenberg and published by Karger Medical and Scientific Publishers. This book was released on 2002 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humanity is aging. In the last century, life expectancy has increased by as much as 25 years, the greatest increase in 5'000 years of history. As a consequence the elderly constitute today the fastest growing segment of the world's population. This new situation creates many social problems and challenges to health care which both the developed as well as the developing countries will have to cope with. The present publication shows that scientific progress has reached a level where nutritional interventions may play a decisive part in the prevention of degenerative conditions of age, improvement of quality of life and impact on health care burden and resources. Topics deal with such different aspects as the influence of prenatal and early infant nutrition on the future aged individual and effects of energetic restriction on longevity. Further contributions include studies on mitochondrial alterations, digestive problems, specific metabolic deviations mediated by insulin, bone degradation, structural changes, neuromuscular dysfunctions, mental state of the elderly as well as the response of the immune system to nutrient intake. Finally the book offers a review of requirements appropriate to meet the age-related public health challenges of the 21st century.
