2Studies on the Antibacterial Activity of the Extract of Stachysarpheta angustifolia显示文摘Objective:To investigate the scientific bases for the traditional use of stachytarpheta angustigolia.MEthods:In vitro antibacterial activity of the aqueous and ethanol extract of the plant was investigated using the agar cup plate diffustion method.Results:The ethanol extract of the plant showed antibacterial activity against Escherichia coli,Streptococcus faecalis,Shigella dysenteriae,Staphylococcus aureus(S.aureus),Salmonella sp., pseudomonas aeruginosa and Neisseria gonorthoseae,while the water extract was active against Escherichia coli,Streptococcus faecalis,Shigella dysenteriae,Staphylococcus aureus and Pseudomonas aeruginasa.The ethanol extract exhibited higher antibacterial activity than the water extract,The minimum inhibitory comcentration(MIC) and minimum bactericidal concentration(MBC) of the ethanol extract were0.65g/L and 0.85g/L,respectively.against S.aureus.Treatment of the extract at higher temperature,60℃ increased the sensitivity of the test of ganisms to the plant extract.Phytochemical analysis indicated that the plant possesses tannins,saponins as well as phenols.Concluslon:A scientific basis that the plant possesses antibacterial activity and it could be a probable source of therapeutic agent.Yakubu M Bello Odama L E Nandita B De 2003南京医科大学学报(自然科学版)2003,23,4:7

4Selecting suitable solid organ transplant donors: Reducing the risk of donor-transmitted infections显示文摘Selection of the appropriate donor is essential to a successful allograft recipient outcome for solid organ transplantation. Multiple infectious diseases have been transmitted from the donor to the recipient via transplantation. Donor-transmitted infections cause increased morbidity and mortality to the recipient. In recent years, a series of high-profile transmissions of infections have occurred in organ recipients prompt-ing increased attention on the process of improving the selection of an appropriate donor that balances the shortage of needed allografts with an approach that mitigates the risk of donor-transmitted infection to the recipient. Important advances focused on improving donor screening diagnostics, using previously excluded high-risk donors, and individualizing the selection of allografts to recipients based on their prior infection history are serving to increase the donor pool and improve outcomes after transplant. This article serves to review the relevant literature surrounding this topic and to provide a suggested approach to the selection of an appropriate solid organ transplant donor.Christopher S Kovacs Jr Christine E Koval David van Duin Amanda Guedes de Morais Blanca E Gonzalez Robin K Avery Steven D Mawhorter Kyle D Brizendine Eric D Cober Cyndee Miranda Rabin K Shrestha Lucileia Teixeira Sherif B Mossad 2014World Journal of Transplantation2014,4,2:7
5Intravenous immune globulin suppresses angiogenesis in mice and humans显示文摘Human intravenous immune globulin(IVIg),a purified IgG fraction composed of~60%IgG1 and obtained from the pooled plasma of thousands of donors,is clinically used for a wide range of diseases.The biological actions of IVIg are incompletely understood and have been attributed both to the polyclonal antibodies therein and also to their IgG(IgG)Fc regions.Recently,we demonstrated that multiple therapeutic human IgG1 antibodies suppress angiogenesis in a target-independent manner via FcγRI,a high-affinity receptor for IgG1.Here we show that IVIg possesses similar anti-angiogenic activity and inhibited blood vessel growth in five different mouse models of prevalent human diseases,namely,neovascular age-related macular degeneration,corneal neovascularization,colorectal cancer,fibrosarcoma and peripheral arterial ischemic disease.Angioinhibition was mediated by the Fc region of IVIg,required FcγRI and had similar potency in transgenic mice expressing human FcγRs.Finally,IVIg therapy administered to humans for the treatment of inflammatory or autoimmune diseases reduced kidney and muscle blood vessel densities.These data place IVIg,an agent approved by the US Food and Drug Administration,as a novel angioinhibitory drug in doses that are currently administered in the clinical setting.In addition,they raise the possibility of an unintended effect of IVIg on blood vessels.Reo Yasuma Valeria Cicatiello Takeshi Mizutani Laura Tudisco Younghee Kim Valeria Tarallo Sasha Bogdanovich Yoshio Hirano Nagaraj Kerur Shengjian Li Tetsuhiro Yasuma Benjamin J Fowler Charles B Wright Ivana Apicella Adelaide Greco Arturo Brunetti Balamurali K Ambati Sevim Barbasso Helmers Ingrid E Lundberg Ondrej Viklicky Jeanette HW Leusen J Sjef Verbeek Bradley D Gelfand Ana Bastos-Carvalho Sandro De Falco Jayakrishna Ambati 2016Signal Transduction and Targeted Therapy2016,1,1:3

9Competition between fusion-evaporation and multifragmentation in central collisions in ^(58)Ni+^(48)Ca at 25A MeV显示文摘The experimental data concerning the58Ni+48Ca reaction at Elab(Ni)=25A MeV,collected by using the CHIMERA 4π device,have been analyzed in order to investigate the competition among different reaction mechanisms for central collisions in the Fermi energy domain.As a main criterion for centrality selection we have chosen the flow angle(flow) method,making an event-by-event analysis that considers the shape of events,as it is determined by the eigenvectors of the experimental kinetic-energy tensor.For the selected central events(flow >60°) some global variables,good to characterize the pattern of central collisions have been constructed.The main features of the reaction products were explored by using different constraints on some of the relevant observables,like mass and velocity distributions and their correlations.Much emphasis was devoted,for central collisions,to the competition between fusion-evaporation processes with subsequent identification of a heavy residue and a possible multifragmentation mechanism of a well defined(if any) transient nuclear system.Dynamical evolution of the system and pre-equilibrium emission were taken into account by simulating the reactions in the framework of transport theories.Different approaches have been envisaged(dynamical stochastic BNV calculations + sequential SIMON code,QMD,CoMD,etc.).Preliminary comparison of the experimental data with BNV calculations shows reasonable agreement with the assumption of sequential multifragmentation emission in the mass region of IMFs close to the heavy residues.Possible deviations from sequential processes were found for those IMFs in the region of masses intermediate between the mass of heavy residues and the mass of light IMFs.Further simulations are in progress.The experimental analysis will be enriched also by information obtained inspecting the IMF-IMF correlation function,in order to elucidated the nature of space-time decay property of the emitting source associated with events having the largest IMF multiplicity.FRANCALANZA L ABBONDANNO U AMORINI F BARLINI S BINI M BOUGAULT R BRUNO M CARDELLA G CASINI G AGOSTINO M D' De FILIPPO V De SANCTIS J GERACI E GIUSSANI A GRAMEGNA F GUIOT B KRAVCHUK V La GUIDARA E LANZALONE G Le NEINDRE N MAIOLINO C MARINI P MORELLI L OLMI A PAGANO A PAPA M PIANTELLI S PIRRONE S POLITI G POGGI G PORTO F RUSSOTTO P RIZZO F VANNINI G VANNUCCI L 2013Nuclear Science and Techniques2013,24,5:2
