Lymphatic filariasis is the second leading cause of permanent long-term disability globally and control of this disease needs efficient diagnostic methods. In this study, abundantly expressing microfilarial sheath protein (Shp-1) from Brugia malayi was characterized as a filarial diagnostic candidate using samples from different clinical population.(More)
Two new hydroxynaphthyl-hydrazone based fluorogenic chemosensors R1 and R2 have been synthesized by Schiff base condensation of Tris(4-formylphenyl)amine with 1-hydroxynaphthalene-2-hydrazide and 1-hydroxynaphthalene-2-carbohydrazone, respectively. They are examined as highly selective and sensitive receptors for Cu2+ ions in aqueous medium. Electronic(More)
A series of macrobicyclic dizinc(II) complexes [Zn(2)L(1-2)B](ClO(4))(4) (1-6) have been synthesized and characterized (L(1-2) are polyaza macrobicyclic binucleating ligands, and B is the N,N-donor heterocyclic base (viz. 2,2'-bipyridine (bipy) and 1,10-phenanthroline (phen)). The DNA and protein binding, DNA hydrolysis and anticancer activity of these(More)
Lymphatic filariasis is a parasitic disease of tropical countries. This is a disfiguring and painful disease contracted in childhood, but the symptoms become apparent only in later years. Diagnosis of filarial infection is very crucial for the management of the disease. The main objective of this study was to develop a filarial antigen-based immunological(More)
BACKGROUND Lymphatic filariasis is a neglected tropical disease leading to profound disfiguring causing socio economic burden in the tropics. Current diagnosis strategies available during field surveys and epidemics are based on traditional microscopic detections and a few antigen/antibody assays. We have compared different sampling methodologies and(More)
Lymphatic filariasis is a debilitating diseases caused by filarial parasitic nematodes. The infection may be acquired in childhood but the symptoms become apparent only in later life. To evaluate the success of any intervention, sensitive diagnostics were used to identify infection among endemic normals that are likely to develop microfilaremia in due(More)
Global programmes to eliminate lymphatic filariasis (GPELF) require mapping, monitoring and evaluation using filarial antigen diagnostic kits. To meet this objective, a functional single-chain fragment variable (ScFv) specific for filarial Wuchereria bancrofti SXP-1 (Wb-SXP-1) antigen was constructed for the diagnosis of active filarial infection, an(More)
A new benzoyl hydrazone based chemosensor R is synthesized by Schiff base condensation of 2,6-diformyl-4-methylphenol and phenyl carbohydrazide and acts as a highly selective fluorescence sensor for Cu(2+) and Zn(2+) ions in aqueous media. The reaction of R with CuCl2 or ZnCl2 forms the corresponding dimeric dicopper(II) [Cu2(R)(CH3O)(NO3)]2(CH3O)2(More)
