A new 5-O-beta-D-glucopyranosyl-4-(4-hydroxyphenyl)-7-methoxy-2H-chromen-2-one (1), together with four known compounds, one coumarin, 5-O-beta-D-galactopyranosyl-4-(4-hydroxyphenyl)-7-methoxy-2H-chromen-2-one (2) and three cucurbitacins, 23,24-dihydrocucurbitacin F (3), 23,24-dihydro-25-acetylcucurbitacin F (4) and(More)
We present a novel technique to examine cell-cell interactions and directed cell migration using micropatterned substrates of three distinct regions: an adhesive region, a nonadhesive region, and a dynamically adhesive region switched by addition of a soluble factor to the medium. Combining microcontact printing with avidin-biotin capture chemistry, we(More)
The initial steps of gluconate metabolism in E. coli, transport and phosphorylation, occur through duplicate activities. These activities have been included in two systems designated as GntI (main) and GntII (subsidiary), encoded by differently regulated operons located at the 76.4-77 and 95.3-96.9 regions on the map respectively. Despite recent molecular(More)
