1Effects of nanotopography on stem cell phenotypes显示文摘Stem cells are unspecialized cells that can self renew indefinitely and differentiate into several somatic cells given the correct environmental cues.In the stem cell niche,stem cell-extracellular matrix(ECM)interactions are crucial for different cellular functions,such as adhesion,proliferation,and differentiation.Recently, in addition to chemical surface modifications,the importance of nanometric scale surface topography and roughness of biomaterials has increasingly becoming recognized as a crucial factor for cell survival and host tissue acceptance in synthetic ECMs.This review describes the influence of nanotopography on stem cell phenotypes.Rajeswari Ravichandran Clarisse CH Ng Casey K Chan Michael Raghunath Seeram Ramakrishna 2009World Journal of Stem Cells2009,1,1:3
2Decomposition and Reformulation of Banxia Baizhu Tianma Decoction:A Vasodilatory Approach显示文摘Objective To decompose and reformulate Banxia Baizhu Tianma Decoction(BBT) in order to optimize its ratio for vasodilatory effect.The fingerprints of these six component herbs were also studied via Tri-step FTIR analysis.Methods The herbal components of BBT were extracted separately with different solvents,such as 95%ethanol,50%ethanol,and distilled water.The vasodilatory effect of the extracts was studied using the in vitro pre-contracted aortic ring model.Among these extracts,the water extracts of Pinellia ternata[PT(W)]and Citri reticulatae[CR(W)],50%ethanol extracts of Castrodia elata[GE(50)]and Clycyrrhiza uralensis[GU(50)],and 95%ethanol extracts of Atractylodes macrocephala[AM(E)],and Poria cocos[PC(E)]were selected for the orthogonal stimulus-response compatibility group study due to their high effectiveness in vasodilation.Results The best combination ratio(G2) was GE(50),GU(50),AM(E),PC(E),CR(W),and PT(W) at EC_0,EC_5,EC_5,EC_5,EC_5,and EC_5,with EC_(50) of(0.06 ± 0.01) mg/mL.Comparison between the vasodilatory effects of extracts derived from G2 and BBT were also studied.From the results,the 50%ethanol extract following G2 ratio was found to be most potent extract with the highest vasodilatory effect compared with other extracts derived from G2 or BBT,with EC_(50) of(0.05 ±0.005) mg/mL.Conclusion The optimum ratio and appropriate extraction method for the new BBT formulae are obtained.G2 is determined as the best formulae with the highest potency in producing the vasodilatory effect on isolated rat aortic rings.The results obtained suggest that 50%ethanol is found to be the best solvent to extract the vasoactive compounds of G2 in order to exhibit the highest efficacy of vasodilatory effect.Chu Shan Tan Yean Chun Loh Yung Sing Ch'ng Mariam Ahmad Mohd.Zaini Asmawi Mun Fei Yam 2017Chinese Herbal Medicines2017,9,2:3
3RATIONAL GENERAL SOLUTIONS OF HIGHER ORDER ALGEBRAIC ODES显示文摘This paper generalizes the method of Ngo and Winkler(2010,2011)for finding rational general solutions of a first order non-autonomous algebraic ordinary differential equation(AODE)to the case of a higher order AODE,provided a proper parametrization of its solution hypersurface.The authors reduce the problem of finding the rational general solution of a higher order AODE to finding the rational general solution of an associated system.The rational general solutions of the original AODE and its associated system are in computable 1-1 correspondence.The authors give necessary and sufficient conditions for the associated system to have a rational solution based on proper reparametrization of invariant algebraic space curves.The authors also relate invariant space curves to first integrals and characterize rationally solvable systems by rational first integrals.HUANG Yanli NG L X Chu WINKLER Franz 2013Journal of Systems Science & Complexity2013,26,2:3
4Chemical constituents and pharmacological effects of durian shells in ASEAN countries:A review显示文摘Durio zibethnus is mainly distributed in Southeast Asia.Traditional Chinese medicine believes that durian shells have the effects of clearing heat and purging fire,nourishing yin and moisturizing dryness.Therefore,it is often used as a pharmaceutic food in the Chinese folk to assist treating diseases.At present,the chemical constituents isolated from durian shell include phenolic acids,phenolic glycosides,flavonoids,coumarins,triterpenes,simple glycosides and other compounds.Modern pharmacological studies show that durian shell has many pharmacological activities,such as antioxidant,antiinflammatory,regulation of glucose and lipid metabolism.The chemical composition and pharmacological effects of durian shells are summarized in order to provide references for the further research and application of durian shell.Yuan-fei Zhan Xiao-tao Hou Li-li Fan Zheng-cai Du Soo Ee Ch'ng Siok Meng Ng Khamphanh Thepkaysone Er-wei Hao Jia-gang Deng 2021Chinese Herbal Medicines2021,13,4:2
