In response to inflammatory signals, microglia become activated and transform their morphology into a thick, amoeboid-like shape. Activated microglia proliferate, tolerate to sites of iniurv,展开更多

Metabolic nitrogen balance studies, conducted in 1957 by Rose in human adults and in 1959 by Snyderman and coworkers in young infants, revealed that a dietary source of this amino acid was not an obligatory requirement for growth and maintenance of nitrogen homeostasis in healthy individuals. Hence, It was initially classified as a non-essential (dispensable) amino acid and, perhaps, for reasons of this classification arginine did not receivc the earlier atteniion it now deserves, in relation to an understanding of the nutritional biochemistry and physiology of its metabolism in humans subjects. However, there is currently a considerable interest in the cellular and tissue functions, as well as clinical, therapeutic significance, of arginine. In this paper we review the multiple functions of arginlne, including its role in the L-arginine-nitric oxide pathway,cellular regeneration, immune function, protein synthesis and protein breakdown. We then consider some in vivo aspects of the physiology of arginine metabolism, which varies greatly among eukaryotes, with particular reference to humans. Against this background, studies of arginine in the nutrition of humans under various pathophysiological conditions are reviewed briefly. Finally, a new, updated concept for the metabolic basis for the 'conditional essentiality' of arginine is proposed展开更多

Questionnaires and interviews were employed to collect data from those whose careers and lives are affected, and were affected, by the buildings. The investigation reveals that people show significantly different attitudes towards the two types of buildings and place more value on old buildings. People particularise their liking for old buildings associated with traditional values, aesthetic quality and conformity to surroundings whereas indicates their disliking for new ones with changed values from tradition to modernity, unsound administrative management and poor respect for surroundings. It is concluded that traditional ideology tends to be well expressed by the old buildings but poorly by new ones. It is accordingly suggested that ideology should be taken more into account in new building projects in Mount Emei.展开更多
