| 1 | Biosynthesis of silver nanoparticles by using mangrove plant extract and their potential mosquito larvicidal property显示文摘Objective:To identify the larvicidal activities of silver nano particles synthesised with Rhizophora mucronata(R.mucronata) leaf extract against the larvae of Aedes aegypti(Ae.aegypti) and Culex quinquefasciatus(Cx.quinquefasciatus).Methods:In vitro larvicidal activities such as LC50 and LC90 were assessed for the Ae.aegypti and Cx.quinquefasciatus larval species.Further, characterisation such as UV,XRD,FTIR and AFM analysis were carried out for the synthesised silver nano particles.Results:The LC50 value of the synthesised silver nano particle was identified as 0.585 and 0.891 mgg/L for Ae.aegypti and Cx.quinquefasciatus larvae respectively. Further,the LG90 values are also identified as 2.615 and 6.291 mg/L for Ae.aegypti and Cx. quinquefasciatus species respectively.The synthesised silver nanoparticles have maximum absorption at 420 nm with the average size of 60-95 nm.The XRD data showed 20 intense values with various degrees such as 37.10°,47.66°,63.97°and 70.01°.The FTIR data showed prominent peaks in(3 426.89,2 925.49,2 869.56,2 346.95,1 631.49,1 031.73,669.18 and 455.12) different ranges.Conclusions:The biosynthesis of silver nanoparticles with leaf aqueous extract of R. mucronata provides potential source for the larvicidal activity against mosquito borne diseases. | M Gnanadesigan M Anand S Ravikumar M Maruthupandy V Vijayakumar S Selvam M Dhineshkumar AK Kumaraguru | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，10： | 4 |
| 2 | Anticancer property of sediment actinomycetes against MCF-7 and MDA-MB-231 cell lines显示文摘Objective:To investigate the anticancer property of marine sediment actinomvceles against two different breast cancer cell lines.Methods:In vitro anticancer activity was carried out against breast(MCF-7 and MDA-MB-231)cancer cell lines.Partial sequences of the 16s rRNA gene,phylogenetic tree construction,multiple sequence analysis and secondary structure analysis were also carried out with the actinomycetes isolates.Results:Of the selected five actinomycete isolates,ACT01 and ACT02 showed the IC_(50)value with(10.13±0.92)and(22.34±5.82)μg/mL concentrations,respectively for MCF-7 cell line at 48 h,but ACT01 showed the minimum(18.54±2.49μg/mL)level of IC_(50)value with MDA-MB-231 cell line.Further,the 16s rRNA partial sequences of ACT01,ACT02,ACT03,ACT04 and ACT05 isolates were also deposited in NCBI data bank with the accession numbers of GQ478246,GQ478247,GQ478248,GQ478249 and GQ478250.respectively.The phylogenetic tree analysis showed that,the isolates of ACT02 and ACT03 were represented in groupⅠandⅢ,respectively,but ACT01 and ACT02 were represented in groupⅡ.The multiple sequence alignment of the actinomycete isolates showed that,the maximum identical conserved regions were identified with the nucleotide regions of 125 to 221st base pairs,65 to 119th base pairs and 55,48 and 31st base pairs.Secondary structure prediction of the 16s rRNA showed that,the maximum free energy was consumed with ACT03 isolate(-45.4 kkal/mol)and the minimum free energy was consumed with ACT04 isolate(-57.6 kkal/mol).Conclusions:The actinomycete isolates of ACT01 and ACT02(GQ478246 and GQ478247)which are isolated from sediment sample can be further used as anticancer agents against breast cancer cell lines. | Ravikumar S Fredimoses M Gnanadesigan M | 2012 | Asian Pacific Journal of Tropical Biomedicine2012，2，2： | 4 |
