Transport Mechanisms Of Tryptophan In Blood Cells Nerve Cells And At The Blood Brain Barrier

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.

First multi-year cumulation covers six years: 1965-70.

It is more recently becoming increasingly clear, however, that the homeostatic equilibrium, and its physiological and pathological changes, are governed by a complex set of mechanisms residing heterogeneously in a complex set of membranes. Mechanisms residing in the capillary endothelium are of importance - especially in short term penetration studies of administered substances from blood to brain; the physiological and pathological equilibria are likely to be more influenced and governed by mechanisms residing in neuronal, glial, nuclear, and lysosomal membranes, to name a few. For functional importance in turn, mechanisms residing in mitochondrial and synaptosomal membranes are of crucial importance, for transport out of the system those present in choroid plexus among others have to be studied.
