1Antibacterial activity and characterization of secondary metabolites isolated from mangrove plant Avicennia officinalis显示文摘Objective:To explore antibacterial activity and characterization of secondary metabolites isolated from mangrove plant Avicennia officinalis(A.officinalis).Methods:In the present study the leaf extracts of A.officinalis were examined for its antibacterial potential using five different solvents against some reference strains of human pathogenic bacteria for the crude extract.Maximum activity was observed for ethyl acetate and hence different concentrations like 15μL,25μL,and 50μL of ethyl extracts was checked for its antibacterial activity.Partial purification of crude extract was carried by column chromatography and fractions were analyzed using gas chromatography-mass spectrometry(GC-MS) to identify compounds.Results:The crude ethyl acetate extracts of A.officinalis showed remarkable antibacterial activity with zones of inhibition of 13 mm against Eschericia coli(E.coli) and 11 mm against Staphylococcus aureus (S.aureus).Fraction 13(ethyl acetate:methanol= 8:2) as the most potent one against with the minimal inhibitory concentration of 30 mm against E.coli and 25 mm against S.aureus.The GCMS resultsof active column fraction(F13) revealed that the active principals were a mixture of hydroxy- 4 methoxybenzoic acid,diethyl phthalate,oleic acid.Conclusions:The leaf extracts with proven antibacterial effects can clearly be directed towards cancer treatment as to inhibiting cancer cell growth.The limited number of test organisms owes to a constraint of resource.So,the effect of strong bursts of leaf extracts on human pathogenic bacteria should further be tested on a wide range of test organisms.Valentin Bhimba B J Meenupriya Elsa Lycias Joel D Edaya Naveena Suman kumar M Thangaraj 2010Asian Pacific Journal of Tropical Medicine2010,3,7:13
2嗜曙红血球过多: 在童年的动脉的血栓和 cardioembolic 击的稀罕原因显示文摘 Eosinophilia has been reported as a very rare cause of stroke in children.The thrombotic event may be either due to cardiac damage induced by eosinophils and their granular protein,that is,the major basic protein,or the systemic hypercoagulable state induced by eosinophilia.We report here a case of eosinophilia whose initial presentation was recurrent strokes and cardiac and arterial thrombosis.Sanjeev Kumar Sharma Suman Kumar Tulika Seth Pravas Mishra Manoranjan Mahapatra 2012World Journal of Cardiology2012,4,4:5
3Microstructure,mechanical response and fractography of AZ91E/Al_(2)O_(3)_(p) nano composite fabricated by semi solid stir casting method显示文摘The present study confers to the fabrication and its characterization of magnesium alloy(AZ91E)based nano composites with nano Al_(2)O_(3) particulate reinforcements.A novel Semi Solid stir casting technique was adopted for the fabrication of the composite.An average particle size of 50 nm was used as reinforcement to disperse in matrix.The effects of change in weight fraction of reinforcements on the distribution of particles,particle–matrix interfacial reactions,physical as well as mechanical properties were reported.The SEM and EDS analysis has shown the uniform distribution of particles in the composite along with the presence of elements.The mechanical properties of reinforced and unreinforced composite were evaluated and presented.Fractography of tensile specimens was also discussed.Sameer Kumar D Suman K.N.S Tara Sasanka C Ravindra K Palash Poddar 2017Journal of Magnesium and Alloys2017,5,1:4

14Prospects and advancements in C-reactive protein detection显示文摘C-reactive protein(CRP) is one of the earliest proteins that appear in the blood circulation in most systemic inflammatory conditions and this is the reason for its significance,even after identification of many organ specific inflammatory markers which appear relatively late during the course of disease.Earlier methods of CRP detection were based on the classical methods of antigen-antibody interaction through precipitation and agglutination reactions.Later on,CRP based enzymatic assays came into the picture which were further modified by integration of an antigen-antibody detection system with surface plasma spectroscopy.Then came the time for the development of electrochemical biosensors where nanomaterials were used to make a highly sensitive and portable detection system based on silicon nanowire,metal-oxide-semiconductor field-effect transistor/bipolar junction transistor,ZnS nanoparticle,aptamer,field emission transmitter,vertical flow immunoassay etc.This editorial attempts to summarize developments in the field of CRP detection,with a special emphasis on biosensor technology.This would help in translating the latest development in CRP detection in the clinical diagnosis of inflammatory conditions at an early onset of the diseases.Pranjal Chandra Pankaj Suman Himangi Airon Monalisa Mukherjee Prabhanshu Kumar 2014World Journal of Methodology2014,4,1:1
