A 45-kDa midgut glycoprotein from Anopheles albimanus mosquito mediates the killing of trypanosomes.
Cell Biochem. Funct. 20(3) , 257-62, (2002) Trypanosomes do not inhabit or grow in anopheles mosquitoes, the vector for the transmission of Plasmodium parasites the causative agent for malaria. The possession of lytic factors by the anopheline mosquito was thus considered. Head and midgut sections prep... |

[A combined chromogenic-fluorogenic medium for the simultaneous detection of coliform groups and E. coli in water].
Zentralbl. Hyg. Umweltmed. 189 , 225, (1989) A comparison was made with different chromogenic and fluorogenic substrates, 4-methylumbelliferyl-beta-D-glucuronide (MUG), 4-nitrophenyl-beta-D-glucuronide (PNPG), 4-methylumbelliferyl-beta-D-galactopyranoside (MUGA), 2-nitrophenyl-beta-D-galactopyranoside (... |

The chaperone activity and toxicity of ambroxol on Gaucher cells and normal mice.
Brain Dev. 35(4) , 317-22, (2013) Gaucher disease (GD), caused by a defect of acid β-glucosidase (β-Glu), is one of the most common sphingolipidoses. Recently, ambroxol, an FDA-approved drug used to treat airway mucus hypersecretion and hyaline membrane disease in newborns, was identified as ... |

Rapid detection of fluorescent and chemiluminescent total coliforms and Escherichia coli on membrane filters.
J. Microbiol. Methods 42(3) , 233-44, (2000) The detection of fluorescent colonies of Escherichia coli/total coliforms (TC) on a membrane filter is currently carried out using 4-methylumbelliferyl-beta-D-glycosides as enzyme substrates and a UV-lamp for visualization. The most rapid procedures based on ... |

Comparison of the recoveries of Escherichia coli and total coliforms from drinking water by the MI agar method and the U.S. Environmental Protection Agency-approved membrane filter method.
Appl. Environ. Microbiol. 62(1) , 203-8, (1996) Drinking water regulations under the Final Coliform Rule require that total coliform-positive drinking water samples be examined for the presence of Escherichia coli or fecal coliforms. The current U.S. Environmental Protection Agency-approved membrane filter... |

Thermodynamic and kinetic studies on the mechanism of binding of methylumbelliferyl galactosides to the basic agglutinin from winged bean (Psophocarpus tetragonolobus).
J. Biol. Chem. 268(22) , 16378-87, (1993) The binding of winged bean basic agglutinin (WBA I) to 4-methylumbelliferyl (MeUmb) galactosides was examined by extrinsic fluorescence titration and stopped-flow spectrofluorimetry. Upon binding to WBA I, MeUmb alpha-galactosides show quenching in fluorescen... |

Physicochemical studies of binding of 4-methylumbelliferyl beta-D-galactopyranoside to cold agglutinin.
Biochem. J. 262(1) , 357-60, (1989) The fluorescence of 4-methylumbelliferyl beta-D-galactopyranoside (MeUmbGalp) was quenched in the presence of cold agglutinin, showing that there was binding between MeUmbGalp and cold agglutinin. That binding was saccharide-specific. By using this quenching ... |

Globoid cell leukodystrophy (Krabbe disease): normal umbilical cord blood galactocerebrosidase activity and polymorphic mutations.
J. Inherit. Metab. Dis. 28(6) , 1005-9, (2005) Globoid cell leukodystrophy is an inherited metabolic disorder of the central nervous system caused by deficiency of the lysosomal enzyme galactocerebrosidase. Haematopoietic stem cell transplantation is the only available effective treatment. The engraftment... |

Fluorometric assay of binding specificity of plant lectins to yeast cells by biotin-avidin system and its application to the classification of yeast cells.
Anal. Biochem. 254(1) , 41-8, (1997) A fluorometric assay of lectin binding to yeast cells is reported. The relative amount of biotinylated lectins bound to the yeast cells was estimated by enzyme activity using 4-methylumbelliferyl-beta-D-galactoside as a substrate for the lectin-bound beta-gal... |
