Inhibition of maltase, sucrase, isomaltase and glucoamylase activity by acarbose, epigallocatechin gallate, epicatechin gallate four polyphenol-rich tea extract from white, green, oolong, black tea, were investigated using rat intestinal enzymes human Caco-2 cells. Regarding enzyme mixture, all extracts very effective in inhibiting maltase activity, but only white inhibited sucrase the inhibiti...

Cedar waxwings (Bombycilla cedrorum) feed predominantly on fruits that are rich in simple sugars and low in nitrogen, supplementing this diet with arthropod prey during the summer months as well as flowers and tree sap in springtime. In contrast, thrushes feed extensively on fatty, protein-rich invertebrate prey, supplemented with sugary and lipid-rich fruits. Simple sugars and fats are digeste...

Monoclonal antibodies to maltase (alpha-D-glucoside glucohydrolase, EC 3.2.1.20) from young adult and aged rats were prepared by the hybridoma technique. Four cell lines producing antibodies of the IgG1 subclass to maltase were established. Two, designated 1F12E1 and 8B1G6, produced monoclonal antibodies specific for the catalytically active form of the enzyme found predominantly in enzyme prep...

AIMS To evaluate the rapid identification of Candida glabrata using a one minute trehalase and maltase test in four clinical laboratories. METHOD The test was evaluated with 944 freshly isolated yeasts comprising 572 C glabrata and 372 non-C glabrata strains. These strains were isolated on one of three differential media-Candida ID, CHROMagar Candida, or Albicans ID2 medium-and all strains we...

Two membrane proteins, maltase and gp330 (the pathogenic antigen of Heymann nephritis), present in the proximal tubule brush border have recently been independently purified and found to be large glycoproteins of similar molecular weight (Mr = approximately 300,000) by SDS PAGE. To determine the relationship between the two, monoclonal antibodies raised against the purified proteins were used f...
