A mild and expedient one-pot synthesis of substituted benzimidazoles in water using a phase-transfer catalyst
(SPRINGER, 2009-04)1-Alkyl/phenyl-2-arylbenzimidazoles have been synthesized in very good to excellent yields by a one-pot condensation of N-alkyl/phenyl-o-phenylenediamines with aryl aldehydes in water at room temperature using cetyl-pyridinium ... -
Antibiotics, arsenate and H2O2 induce the promoter of Staphylococcus aureus cspC gene more strongly than cold
(WILEY-BLACKWELL, 2009-04)Proteins expressed by the bacterial cold shock genes are highly conserved at sequence level and perform various biological functions in both the cold-stressed and normal cells. To study the effects of various agents on the ... -

Helicobacter pylori Protein HP0175 Transactivates Epidermal Growth Factor Receptor through TLR4 in Gastric Epithelial Cells
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY, 2008-11-21)The pathophysiology of Helicobacter pylori-associated gastroduodenal diseases, ulcerogenesis, and carcinogenesis is intimately linked to activation of epidermal growth factor receptor (EGFR) and production of vascular ... -
Characterization of a low-molecular-mass stimulator protein of Mg2+-independent Ca2+-ATPase: effect on phosphorylation/dephosphorylation, calcium transport and sperm-cell motility
(PORTLAND PRESS, 2008-04)A 14 kDa cytosolic protein purified from bovine brain homogenate has been recently reported as a stimulator of goat spermatozoa Mg2+-independent Ca2+-ATPase. In the present study, we demonstrate the formation of the ... -
Agronomic, genetic and molecular characterization of MYMIV-tolerant mutant lines of Vigna mungo
(Science Alert, 2009)The Mungbean Yellow Mosaic India Virus (MYMIV), transmitted through Bemisia tabaci causes severe damage in several grain legrnnes. Three mutant MYMIVtolerant lines, namely, VM 1, VM 4 and VM 6, along with the susceptible ... -
Localization and expression of a 70 kDa protein in goat spermatozoa having Na+,K+-ATPase inhibitory and arylsulphatase A activities
(SPRINGER, 2009-01)We have previously isolated and purified a goat sperm protein of 70 kDa molecular weight designated as P70 and characterized it as an inhibitor of Na+,K+-ATPase. Our study reveals that the first 10 amino acid residues from ... -
Anti-inflammatory effect of allylpyrocatechol in LPS-induced macrophages is mediated by suppression of iNOS and COX-2 via the NF-kappa B pathway
(ELSEVIER SCIENCE BV, 2008-09)The crude ethanol extract of Piper betle leaf is reported to possess anti-inflammatory activity which has been suggested to be mediated by allylpyrocatechol (APC). In the present study, we have demonstrated the anti-inflammatory ... -
Cholesterol depletion associated with Leishmania major infection alters macrophage CD40 signalosome composition and effector function
(NATURE PUBLISHING GROUP, 2009-03)CD40, a costimulatory molecule expressed on macrophages, induces expression of interleukin 12 (IL-12) in uninfected macrophages and IL-10 in macrophages infected with Leishmania major. IL-12 suppresses, whereas IL-10 ... -
Homodimeric Alkaline Phosphatase Located at Helicoverpa armigera Midgut, a Putative Receptor of Cry1Ac Contains alpha-GaINAc in Terminal Glycan Structure as Interactive Epitope
(AMER CHEMICAL SOC, 2009-04)Helicoverpa armigera causes massive yield loss of various crops globally. Bacillus thuringiensis coded Cry1Ac toxin is effective against the pest. Through the present investigation, an alkaline phosphatase type putative ... -
Arabinosylated lipoarabinomannan modulates the impaired cell mediated immune response in Mycobacterium tuberculosis H37Rv infected C57BL/6 mice
(ELSEVIER SCIENCE BV, 2008-04)Mycobacterium tuberculosis is a facultative intracellular pathogen that flourishes inside the host macrophages. This organism has the ability to deactivate the cell-mediated immune responses involving the down-regulation ... -
Effectiveness of garlic lectin on red spider mite of tea
