Loop mediated isothermal amplification (LAMP) is a powerful innovative gene amplification technique emerging as a simple rapid diagnostic tool for early detection and identification of microbial diseases. The whole procedure is very simple and rapid wherein the amplification can be completed in less than 1 h under isothermal conditions employing a set of(More)
The cyclic peptide toxins microcystins and nodularins are the most common and abundant cyanotoxins present in diverse water systems. They have been the cause of human and animal health hazards and even death. Over 60 microcystin variants have been reported so far. We report here the results of our study on comparative toxicity evaluation of three most(More)
Variation in CAPN10, the gene encoding the ubiquitously expressed cysteine protease calpain-10, has been associated with type 2 diabetes in Mexican Americans and in two northern-European populations, from Finland and Germany. We have studied CAPN10 in white subjects of British/Irish ancestry, using both family-based and case-control studies. In 743 sib(More)
Improved molecular understanding of the pathogenesis of type 2 diabetes is essential if current therapeutic and preventative options are to be extended. To identify diabetes-susceptibility genes, we have completed a primary (418-marker, 9-cM) autosomal-genome scan of 743 sib pairs (573 pedigrees) with type 2 diabetes who are from the Diabetes UK Warren 2(More)
The major heat-stable shrimp allergen (designated as Sa-II), capable of provoking IgE-mediated immediate type hypersensitivity reactions after the ingestion of cooked shrimp, has been shown to be a 34-kDa heat-stable protein containing 300 amino acid residues. Here, we report that a comparison of amino acid sequences of different peptides generated by(More)
Dengue is endemic in most parts of the tropics including India. So far, complete genome information for Indian dengue isolates is not available. In the present study, we characterized the genome of three dengue type 3 viruses isolated from India. The genomes of all three viruses were found to be 10,707 bp long with an ORF encoding 3390 aa. Extensive(More)
Dengue virus type 1 (DENV-1) have been mostly circulating silently with dominant serotypes DENV-2 and DENV-3 in India. However recent times have marked an increase in DENV-1 circulation in yearly outbreaks. Many studies have not been carried out on this virus type, leaving a lacunae pertaining to the circulating genotypes, since its earliest report in(More)
Dengue virus infection has recently taken endemic proportion in India implicating all the four known dengue serotypes. There was a major dengue outbreak in northern India including Delhi in October- December, 2003 and again in 2004. We have carried out a detailed investigation of the 2004 outbreak by Serosurveillance, RT-PCR, nested PCR, virus isolation and(More)
Microcystins are cyclic heptapeptide toxins produced by certain strains of Microcystis aeruginosa and microcystin-LR (MC-LR) is the most toxic among the 70 variants isolated so far. These toxins have been implicated in both human and livestock mortality. In the present study we investigated the microcystin-LR induced oxidative stress in mice in terms of its(More)
High frequency somatic embryogenesis was induced from leaf expiants of F1 hybrid Solanum melongena L. on Murashige and Skoog's medium supplemented with 8.0 mg/1 NAA and 0.1 mg/1 Kn. The somatic embryos were encapsulated in various concentrations (2–6%) of sodium alginate and complexed with calcium chloride (25–100mM): 3% sodium alginate and 75 mM calcium(More)
