The event-related potential evoked by the old-new memory recognition task in the oddball paradigm is suitable for examining the neural processes involved in malingered neurocognitive deficits. Forty-four undergraduates were randomly assigned to a simulated malingering group and a truth-telling group, Another 22 patients with head injudes were enrolled as a control group. All participants completed the old-new memory recognition task in the oddball paradigm. The mean P300 amplitude of the simulated malingering group was significantly reduced compared with the truth-telling group (P 〈 0.01), but was increased compared with the control group (P〈 0.01). These results revealed that the P300, evoked by the old-new memory recognition task of the oddball paradigm, may be a helpful indicator for determining cognitive malingering.展开更多

Results indicate that international students significantly increase and adapt their new media use while abroad to communicate globally with their friends and family, and locally with their newly formed relationships. Furthermore, social networking site host national friends do not necessarily lead to the development of face-to-face host national friends;however, interaction with established face-to-face host national friends and friend groups via new media platforms leads to an increased understanding of host communication patterns. Finally, this study proposes that researchers who apply Kim’s [1] cross-cultural adaptation theory consider incorporating Host New Media Communication as a principal concept.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

Therefore,vigorously developing the grape and cherry industries in Shandong Province and carrying out development and innovation are important parts of Shandong Province in responding to the strategy of national new and old kinetic energy conversion. However,currently the germplasm resources preserved in the fruit tree resources banks in China are only 45% of those in the US and 27. 2% of those in the EU. Moreover,the development of fruit trees resources banks in Shandong is relatively backward in China,and there is still no banks related with grape and cherry germplasm resources in Shandong. Therefore,importance can be attached to the agriculture,forestry,and animal husbandry to build germplasm resources banks for grape and cherry industries in Shandong Province. Building the national-level grape and cherry germplasm resources bank in Shandong Province can also promote the utilization of wild and farm germplasm resources in the future; advance the research on the genes related to disease resistance,stress resistance and quality of grapes and cherries; push forward the construction and development of cherry and grape mutants banks. It is conducive to the research on the agronomic traits of grapes and cherries,and can provide the parents resources for planting innovation and improving the quality of grapes and cherries,as well as promote the development and application of molecular markers of grapes and cherries,including the identification of lines and crossbreeding. Thereby,it cannot only promote the industry development,but also achieve the development of cultivation,breeding and basic research in an all-round way and the development of " production,study and research" going side by side.展开更多

文摘The current study uses a longitudinal, mixed-method approach to investigate the role that new media, such as social networking sites and video chat, play in cross-cultural adaptation and international student friendship network development. Results indicate that international students significantly increase and adapt their new media use while abroad to communicate globally with their friends and family, and locally with their newly formed relationships. Furthermore, social networking site host national friends do not necessarily lead to the development of face-to-face host national friends;however, interaction with established face-to-face host national friends and friend groups via new media platforms leads to an increased understanding of host communication patterns. Finally, this study proposes that researchers who apply Kim’s [1] cross-cultural adaptation theory consider incorporating Host New Media Communication as a principal concept.
