| 1 | On the infimum problem of Hilbert space effects显示文摘The quantum effects for a physical system can be described by the set ε(H) of positive operators on a complex Hilbert space Hthat are bounded above by the identity operator Ⅰ. The infimum problem of Hilbert space effects is to find under what condition the infimum A∧B exists for two quantum effects A and B ∈ε(H). The problem has been studied in different contexts by R. Kadison, S. Gudder, M. Moreland, and T. Ando. In this note, using the method of the spectral theory of operators, we give a complete answer of the infimum problem. The characterizations of the existence of infimum A ∧ B for two effects A, B ∈ε(H) are established. | DU Hongke DENG Chunyuan LI Qihui | 2006 | Science China Mathematics2006，49，4： | 16 |
| 2 | Engineering white blood cell membrane-camouflaged nanocarriers for inflammation-related therapeutics显示文摘White blood cells(WBCs)play essential roles against inflammatory disorders,bacterial infections,and cancers.Inspired by nature,WBC membrane-camouflaged nanocarriers(WBC-NCs)have been developed to mimic the“dynamic”functions of WBCs,such as transendothelial migration,adhesion to injured blood vessels,etc,which make them promising for diverse medical applications.WBC-NCs inherit the cell membrane antigens of WBCs,while still exhibiting the robust inflammation-related therapeutic potential of synthetic nanocarriers with excellent(bio)physicochemical performance.This review summarizes the proposed concept of cell membrane engineering,which utilizes physical engineering,chemical modification,and biological functionalization technologies to endow the natural cell membrane with abundant functionalities.In addition,it highlights the recent progress and applications of WBC-NCs for inflammation targeting,biological neutralization,and immune modulation.Finally,the challenges and opportunities in realizing the full potential of WBC-NCs for the manipulation of inflammation-related therapeutics are discussed. | Wanli Song Pengfei Jia Yaping Ren Junmiao Xue Bingqian Zhou Xinkai Xu Yansheng Shan Jing Deng Qihui Zhou | 2023 | Bioactive Materials2023，，5： | 1 |

| 4 | Soybean protein concentrate causes enteritis in juvenile pearl gentian groupers(Epinephelus fuscoguttatus♀×Epinephelus lanceolatus♂)显示文摘Due to diminishing fish meal(FM)supplies,superb protein(PRO)sources are needed for aquaculture,such as soy-based PRO.However,these can cause enteritis and even intestinal injury in fish when used at high proportions in feed.This research examines the effects of substituting soybean protein concentrate(SPC)for FM on the growth performance and intestinal balance of pearl gentian groupers and investigates the mechanism of SPC-induced enteritis.Experimental fish(n=720)were fed 1 of 3 following diets:(1)a 50%FM diet(control),(2)a diet with 20%of the FM substituted with SPC(group SPC20),and(3)a 40%SPC-substituted diet(SPC40).Fish were fed for 10 wk iso-nitrogenous(50%PRO)and iso-lipidic(10%lipid)diets.Groups SPC20 and SPC40 showed significantly lower developmental performance and intestinal structures than control.Group SPC40 had significantly higher expressions of pro-inflammatory-related genes,such as interleukin 1β(IL1β),IL12,IL17 and tumor necrosis factorαand significantly lower expressions of anti-inflammatory-related genes,such as IL5,IL10 and transforming growth factorβ1.Biochemical and 16S high-throughput sequencing showed that the abundance and functions of intestinal flora in group SPC40 were significantly affected(P<0.05),and there were significant correlations between operational taxonomic unit abundance variations and inflammatory gene expressions at genus level(P<0.05).The second-and third-generation full-length transcriptome sequence was used to analyze the mechanism of SPC-induced enteritis in pearl gentian groupers,which showed that enteritis induced by SPC may be caused by disturbances to intestinal immune function induced by an imbalance in intestinal nutrition and metabolism,such as the intestinal immunity network for IgA production pathway.However,it remains unclear as to which intestinal immune or nutritional imbalance is most important in enteritis development.This study provides a basis for further research into soy PRO-related enteritis in fish. | Wei Zhang Beiping Tan Junming Deng Qihui Yang Shuyan Chi Aobo Pang Yu Xin Yu Liu Haitao Zhang | 2023 | Animal Nutrition2023，，1： | 0 |
| 5 | Adsorption performance and physicochemical mechanism of MnO_(2)-polyethylenimine-tannic acid composites for the removal of Cu(Ⅱ) and Cr(Ⅵ) from aqueous solution显示文摘In this work,an adsorbent,which we call MnPT,was prepared by combining MnO_(2),polyethylenimine and tannic acid,and exhibited efficient performance for Cu(Ⅱ) and Cr(VI) removal from aqueous solution.The oxygen/nitrogen-containing functional groups on the surface of MnPT might increase the enrichment of metal ions by complexation.The maximum adsorption capacities of MnPT for Cu(Ⅱ) and Cr(Ⅵ) were 121.5 and 790.2 mg·g^(-1),respectively.The surface complexation formation model was used to elucidate the physicochemical interplay in the process of Cu(Ⅱ) and Cr(Ⅵ) co-adsorption on MnPT.Electrostatic force,solvation action,adsorbate-adsorbate lateral interaction,and complexation were involved in the spontaneous adsorption process.Physical electrostatic action was dominant in the initial stage,whereas chemical action was the driving force leading to adsorption equilibrium.It should be noted that after adsorption on the surface of MnPT,Cr(Ⅵ) reacted with some reducing functional groups(hydroxylamine-NH_(2))and was converted into Cr(Ⅲ).The adsorption capacity declined by 12% after recycling five times.Understanding the adsorption mechanism might provide a technical basis for the procedural design of heavy metal adsorbents.This MnPT nanocomposite has been proven to be a low-cost,efficient,and promising adsorbent for removing heavy metal ions from wastewater. | Xiaoyan Deng Luxing Wang Qihui Xiu Ying Wang Hong Han Dongmei Dai Yongji Xu Hongtao Gao Xien Liu | 2021 | Frontiers of Chemical Science and Engineering2021，15，3： | 0 |
