Urban Waterfront Park Plant Landscape Design—Take Ganjiang Citizen Park as an Example
The design of waterfront parks is discussed with the aim of enhancing the ornamental nature of waterfront landscape greenery and enriching urban public space. In the urban waterfront, vegetation is a kind of landscape with various functions such as ecological, ornamental and aesthetic, which plays a pivotal role in improving people’s quality of life, ecological quality of life and urban image. Through the study of the basic principles and arrangement of waterfront urban landscaping, it has certain guiding significance for the planning and arrangement of waterfront park greenery
The Combination of Chinese and Western Sculpture Art and the Future Direction
Sculpture art is the physical form of human emotion overflow. Sculpture is an important part of Chinese and Western culture. Whether ancient or modern, the creation of sculpture reflects the cultural spirit of the times. Due to the different cultural backgrounds, the themes of Chinese and Western sculpture art show great differences. The different cultures of China and the West determine that there are great differences between Chinese and Western sculpture art. With the development of economic globalisation, the collision and fusion of Chinese and Western cultures have prompted Chinese contemporary sculpture to present a combination of traditional and Western cultures. The performance of traditional and western culture in modern sculpture is analysed, and an effective way of combining Chinese and western culture is proposed from three aspects: theory and practice, connotation and function, and realism and realism. Sculpture art, as one of the important forms of artistic expression, is able to show the great differences between Chinese and Western cultures. The development of contemporary sculpture art, to recognize the significance of cultural integration and development, and to seek ways to effectively combine traditional Chinese culture with Western culture, so as to better promote the development of modern sculpture art
The Ameliorate Effect of Endomorphin 1 on the Mice Nephrotoxicity Induced by Cadmium
AbstractTo wonder whether endomorphin 1(EM1), the antioxidative peptide, can protect against the renal toxicology of cadmium (Cd), which probably related to the oxidative injury.MethodsIn vivo assays have been designed and performed, such as the measurement of oxidative damage parameters and the index of antioxidative system.ResultData from our study demonstrated the effect of EM1 could ameliorate the increased concentration of lipid peroxidation products and protein carboxylatio and increase the content of antioxidative system, the antioxidant capacity of EM1 probably relate to its structure.ConclusionOur study first demonstrated the nephrotoxicity induced by Cd can be suppressed by the treatment of EM1
Structure-activity Study of Endomorphins Analogs with C- terminal Substitution
AbstractAims: To further wonder the influence of C-terminal residues on the pharmacological4 activities.Methods: The in vitro and in vivo opioid activities of C-terminal substitution analogs [L-Tic] EM1 and [L-Tic] EM2 were investigated using radioligand binding assay, guinea pig ileum (GPI) assay, mouse vas deferens (MVD) assay, systemic arterial pressure (SAP) assay and tail-flick test.Results: Our data showed that the analogs produced a higher δ-opioid affinity but low colon-opioid affinity, dose-dependent but reduced analgesic activities and cardiovascular effect comparing with those of EMs. Moreover, these effects induced by the analogs can be inhibited by naloxone, indicating an opioid mechanism.Conclusion: These results provided suggestive evidences that the substitution of C-terminal residue may play an important role in the regulation of opioid affinities and pharmacological activities
Transmission electron microscopy analysis of some transition metal compounds for energy storage and conversion
This work was preliminarily supported by the National Key Research Program of China (2016YFA0202604), the Natural Science Foundation of China (21476271), NSFC-RGC (21461162003) and Natural Science Foundation (2014KTSCX004 and 2014A030308012) of Guangdong Province, China.Recently, transition metal compounds (TMCs) have been employed as high-performance electrode materials for lithium ion batteries (LIBs) and supercapacitors (SCs) owing to their high specific capacities, high electrical conductivity, and high chemical and thermal stability. While the characterization of electrochemical properties of TMC anodes is well developed, new challenges arise in understanding the structure-property relationships. Transmission electron microscopy (TEM) is a powerful tool for studying microstructural characteristics. With TEM and related techniques, fundamental understanding of how the microstructures affect the properties of the TMC nanostructured anodes can be improved. In this article, the application of TEM in characterization of some typical TMC anode materials optimized through structural engineering, elemental doping, surface modification, defect-control engineering, morphological control, etc. is reviewed. Emphasis is given on analyzing the microstructures, including surface structures, various defects, local chemical compositions and valence states of transition metals, aimed at illustrating a structure-property relationship. The contribution and future development of the TEM techniques to elucidation of the electrochemical properties of the TMC anodes are highlighted.PostprintPeer reviewe
