The traditional Gossip protocol selects the neighbor nodes randomly. It does not consider the factors, such as the capacities of network transmission and node storage, which affect the network performance. It further causes the drawback of successful search ratio relatively lower, and also network transmission payloads have the characteristics of randomness. In this paper, to overcome those drawbacks of traditional Gossip protocol, a neighbor node selection algorithm has been studied, and various factors that may affect the neighbor node selection have been analyzed in P2P networks. A new neighbor node selection policy has been proposed, which is a reliable Gossip message transmission Protocol based on fuzzy theory. Empirical simulation experiments with various data analysis have demonstrated the improvement of efficiency of the proposed strategy on node selection and correctness of the proposed algorithm in P2P networks.

Controlling Major Cellular Processes of Human Mesenchymal Stem Cells using Microwell Structures
Xu, Xun,Wang, Weiwei,Kratz, Karl,Fang, Liang,Li, Zhengdong,Kurtz, Andreas,Ma, Nan,Lendlein, Andreas Wiley (John WileySons) 2014 Advanced healthcare materials Vol.3 No.12
<P>Directing stem cells towards a desired location and function by utilizing the structural cues of biomaterials is a promising approach for inducing effective tissue regeneration. Here, the cellular response of human adipose-derived mesenchymal stem cells (hADSCs) to structural signals from microstructured substrates comprising arrays of square-shaped or round-shaped microwells is explored as a transitional model between 2D and 3D systems. Microwells with a side length/diameter of 50 관m show advantages over 10 관m and 25 관m microwells for accommodating hADSCs within single microwells rather than in the inter-microwell area. The cell morphologies are three-dimensionally modulated by the microwell structure due to differences in focal adhesion and consequent alterations of the cytoskeleton. In contrast to the substrate with 50 관m round-shaped microwells, the substrate with 50 관m square-shaped microwells promotes the proliferation and osteogenic differentiation potential of hADSCs but reduces the cell migration velocity and distance. Such microwell shape-dependent modulatory effects are highly associated with Rho/ROCK signaling. Following ROCK inhibition, the differences in migration, proliferation, and osteogenesis between cells on different substrates are diminished. These results highlight the possibility to control stem cell functions through the use of structured microwells combined with the manipulation of Rho/ROCK signaling.</P>

The incidence of obesity has risen rapidly in the world, and the occurrence and development of obesity is closely related to the “three high” problem of adolescents after adulthood, which has become one of the most serious public health problems. China's teenagers are not only facing the problem of obesity, but also lack understanding of health-related knowledge, and their health literacy needs to be improved. Based on the analysis of the epidemic trend of adolescent obesity, this paper focuses on the relevant factors affecting the health literacy of obese adolescents, and puts forward countermeasures from the four levels of the country, school, family and individual, in order to improve and enhance their health literacy level, and provide theoretical basis for achieving the overall goal of national health.

Sports injury treatment and sports rehabilitation employing the Nanoparticles containing zinc oxide
Zhichao Ma,Jie Qi,Weiwei Xun,Yaonan Li Techno-Press 2023 Advances in nano research Vol.15 No.1
The combination of physical activities and individual skills in sports creates an entertaining and competitive environment governed by a set of rules. In today's world, sports attract significant attention and are approached differently by various groups. Inevitably, injuries occur in sports, significantly impacting an athlete's performance and ability to participate in exercises and competitions. Addressing this issue, one of the crucial measures involves restoring the athlete's ability to engage in sports and compete. Sports rehabilitation serves as a treatment to mitigate the effects of injuries, and when combined with surgery, it can expedite the recovery process. Therefore, the primary objective of this study is to utilize a biocompatible technology for synthesizing zinc oxide (ZnO) nanoparticles in sports rehabilitation, ensuring minimal harm to the environment.
