Symbiotic Relationship between brain structure and dynamics
BMC Neuroscience, 2009Co-Authors: Mikail Rubinov, Olaf Sporns, Cees Van Leeuwen, Michael BreakspearAbstract:Background Brain structure and dynamics are interdependent through processes such as activity-dependent neuroplasticity. In this study, we aim to theoretically examine this interdependence in a model of spontaneous cortical activity. To this end, we simulate spontaneous brain dynamics on structural connectivity networks, using coupled nonlinear maps. On slow time scales structural connectivity is gradually adjusted towards the resulting functional patterns via an unsupervised, activity-dependent rewiring rule. The present model has been previously shown to generate cortical-like, modular small-world structural topology from initially random connectivity. We provide further biophysical justification for this model and quantitatively characterize the Relationship between structure, function and dynamics that accompanies the ensuing self-organization.

the bacterium wolbachia exploits host innate immunity to establish a Symbiotic Relationship with the dengue vector mosquito aedes aegypti
The ISME Journal, 2018Co-Authors: Andrew Pike, Deepak Joshi, Guowu Bian, Michael J Mcfadden, Peng Lu, Xiao Liang, Fengrui Zhang, Alexander S Raikhel, Zhiyong XiAbstract:A host's immune system plays a central role in shaping the composition of the microbiota and, in return, resident microbes influence immune responses. Symbiotic associations of the maternally transmitted bacterium Wolbachia occur with a wide range of arthropods. It is, however, absent from the dengue and Zika vector mosquito Aedes aegypti in nature. When Wolbachia is artificially forced to form symbiosis with this new mosquito host, it boosts the basal immune response and enhances the mosquito's resistance to pathogens, including dengue, Zika virus and malaria parasites. The mechanisms involved in establishing a Symbiotic Relationship between Wolbachia and A. aegypti, and the long-term outcomes of this interaction, are not well understood. Here, we have demonstrated that both the immune deficiency (IMD) and Toll pathways are activated by the Wolbachia strain wAlbB upon its introduction into A. aegypti. Silencing the Toll and IMD pathways via RNA interference reduces the wAlbB load. Notably, wAlbB induces peptidoglycan recognition protein (PGRP)-LE expression in the carcass of A. aegypti, and its silencing results in a reduction of symbiont load. Using transgenic mosquitoes with stage-specific induction of the IMD and Toll pathways, we have shown that elevated wAlbB infection in these mosquitoes is maintained via maternal transmission. These results indicate that host innate immunity is utilized to establish and promote host-microbial symbiosis. Our results will facilitate a long-term projection of the stability of the Wolbachia-A. aegypti mosquito system that is being developed to control dengue and Zika virus transmission to humans.

Research on the Symbiotic Relationship between Small & Medium-sized Enterprises and Banks in
2020Co-Authors: Jilin Province, Chen LixiaAbstract:As the market economy deepens continually, the small & medium-sized enterprises (SMEs) in Jilin Province play more and more important role for the economic development of Jilin. Although the SMEs in Jilin have developed greatly in recent years, their difficulties in financing seriously hamper their development. The paper analyzes the status of the relation between the SMEs and banks in Jilin and suggests that it is necessary for the SMEs to establish Symbiotic Relationship with banks, we also put forward the paths for them to establish continuous reciprocal Symbiotic relation with banks in order to help SMEs solve their financing problems and guide the

International Business Management, 2011Co-Authors: Chen Lixia, Meng BoAbstract:As the market economy deepens continually, the small & medium-sized enterprises (SMEs) in Jilin Province play more and more important role for the economic development of Jilin. Although the SMEs in Jilin have developed greatly in recent years, their difficulties in financing seriously hamper their development. The paper analyzes the status of the relation between the SMEs and banks in Jilin and suggests that it is necessary for the SMEs to establish Symbiotic Relationship with banks, we also put forward the paths for them to establish continuous reciprocal Symbiotic relation with banks in order to help SMEs solve their financing problems and guide the banks to get more profit to realize win-win for both of them. Key words: Small & Medium-sized enterprises in Jilin Province; banks; Symbiotic Relationship

tourism and marketing a Symbiotic Relationship
Tourism Management, 1991Co-Authors: Chris RyanAbstract:Abstract Tourism has emerged as a major industry throughout the world. Yet, as was demonstrated at the Globe '90 Conference on Tourism in Vancouver, Canada, in March 1990, there is considerable criticism of the impact has had on host communities. This article is written from a European perspective with particular reference to package holidays. Companies and governments in tourism have applied only part of the marketing mix to tourism, ie promotion, with little attention being paid to the other components of marketing, but if tourism is to survive by generating satisfaction among interacting tourists and hosts, it must adopt societal marketing strategies.
