Alkaline phosphatase (APase) of Vibrio cholerae is the first monomeric alkaline phosphatase reported [Roy, N.K., Ghosh, R.K., Das, J., 1982a. Monomeric alkaline phosphatase of V. cholerae. J. Bacteriol. 150, 1033-1039.]. The gene (phoA(VC)) encoding this enzyme is not identified in the published genome sequence of the V. cholerae serogroup O1 El Tor strain(More)
Nine major transfer RNA (tRNA) gene clusters were analysed in variousVibrio cholerae strains. Of these, only the tRNA operon I was found to differ significantly inV. cholerae classical (sixth pandemic) and El Tor (seventh pandemic) strains. Amongst the sixteen tRNA genes contained in this operon, genes for tRNA Gln3 (CAA) and tRNA Leu6 (CUA) were absent in(More)
Antigen retrieval is a standard procedure to enhance immunohistochemical detection. However, among the many choices of techniques available for antigen retrieval, it is important to choose a method that works specifically for the antibody of interest. The small calcium binding protein, Iba1, has been well characterized as a microglia specific marker useful(More)
We have cloned, sequenced and analysed all the five classes of the intergenic (16S-23S rRNA) spacer region (ISR) associated with the eightrrn operons (rrna-rrnh) ofVibrio cholerae serogroup O1 El Tor strains isolated before, during and after the O139 outbreak. ISR classes ‘a’ and ‘g’ were found to be invariant, ISR-B (ISRb and ISRe) exhibited very little(More)
The purpose of this study was to characterize behavioral and physiological effects of a selective thromboxane (TP) receptor antagonist, SQ 29,548, in the C57Bl/6 mouse model. At 6 months of age, male mice were given either sham or drug i.p. injections for 3 days at a dose of 2 mg/kg each day. On the day after the final injection, mice were subjected to(More)
Alzheimer's disease (AD) brains are characterized by fibrillar amyloid-β (Aβ) peptide containing plaques and associated reactive microglia. The proinflammatory phenotype of the microglia suggests that they may negatively affect disease course and contribute to behavioral decline. This hypothesis predicts that attenuating microglial activation may provide(More)
