      • Research on the Digital Multimedia Technology and Urban Landscape Design based on Multimedia Art Perspective

        Wang Aiqing,Wang Xitong,Hou Fengwu 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.10

        21st century is the era of information technology, in this context, form and expression form of art also changed accordingly. The application of multimedia technology can enrich the morphological characteristics and color of different factors. In this paper, we research on the digital multimedia technology application in the urban landscape design, with the rapid development of computer technology, more technical conditions are provided for the multimedia interactive devices. In the design of urban landscape, the use of multimedia technology has also changed the past audio-visual experience, thus creating a novel landscape style. At the same time, we also analyze the computer assisted multimedia technology as CAD, 3D MAX and GIS, these soft wares can help the designer to complete the landscape design more effective, and under the condition of a virtual visualization .

        Rumex hanus by. Extract Protects Against Chronic Alcohol-Induced Liver Injury in Mice

        Meizi Piao,Fengwu Wang,Lingyue Shan,Yang Deng,Tiejun Chen 한국식품영양과학회 2022 Journal of medicinal food Vol.25 No.7

        Alcoholic liver disease (ALD) has become a global health problem. The hepatoprotective effects of bioactive ingredients extracted from Rumex hanus by. on chronic alcoholic liver injury was investigated for the first time. The extract from R. hanus by. (ERHB) was obtained by 70% ethanol extraction, and the endotoxin antagonism rate of ERHB was 88.94 ± 1.24% in vitro. The animal experiments demonstrated that ERHB promoted hepatic function by significantly enhancing the activities of alcohol dehydrogenase and acetaldehyde dehydrogenase, and by reducing the activities of cytochrome P450 proteins, alkaline phosphatase, aspartate aminotransferase, and alanine aminotransferase. Furthermore, ERHB improved alcohol-induced dyslipidemia by regulating lipid metabolism. In addition, ERHB ameliorated the alcohol-induced liver injury by inhibiting endotoxin-caused inflammation. Seven compounds with antagonistic activity on endotoxin were identified in ERHB. These results demonstrated that ERHB had protective effects on ALD and if the results can be confirmed in humans, it might be useful as a functional food supplement for ALD treatment.

        Comparison of Two Varieties Fig (Peggy Red and Green) Peel Extracts by Liquid Chromatography–Tandem Mass Spectrometry Analysis and for Neuroprotective Efficacy in Caenorhabditis elegans

        Shuzhen Liu,Chuxiang Xiao,Fengwu Wang 한국식품영양과학회 2023 Journal of medicinal food Vol.26 No.1

        Previous reports revealed that peel extracts of Ficus carica (fig) have a wide range of pharmacological and biological activities. The current study aimed to determine the phytochemical components of the ethanol extracts of Peggy Red fig (PRF) and Green fig (GF) peels by liquid chromatography–tandem mass spectrometry (LC–MS/MS) analysis, along with its antioxidant properties and neuroprotective effect in Caenorhabditis elegans. LC–MS/MS analysis confirmed 50 compounds in the extract, which revealed the presence of phenols, flavonoids, and anthocyanins, and exhibited in vitro antioxidant activity. PRF and GF peel had 163.25 (mg gallic acid equivalent [mg GAE]) g−1, 125.32 (mg GAE) g−1 of total phenolic content, 62.52 (mg rutin equivalent [mg RE]) g−1, and 43.36 (mg RE) g−1 flavonoids content, respectively. In all antioxidant assays, the extract of PRF peel showed higher antioxidant activity than the GF peel, and the extract of PRF peel could effectively reduce the aggregation of amyloid-beta (Aβ), decrease the paralysis of the body, and increase the antioxidant enzyme activities to reduce the toxicity of Aβ1–42 in Alzheimer's disease (AD) transgenic C. elegans CL4176. Therefore, PRF peel extract may have potential applications as a new source for drug development against AD.
