We consider an age-maturity structured model arising from a blood cell proliferation problem. This model is "hybrid", i.e., continuous in time and age but the maturity variable is discrete. This is due to the fact that we include the cell division marker carboxyfluorescein diacetate succinimidyl ester. We use our mathematical analysis in conjunction with experimental data taken from the divisio...

In the present work, we describe for the first time the specific role of cutinase on surface modification of cellulose acetate fibers. Cutinase exhibits acetyl esterase activity on diacetate and triacetate of 0.010 U and 0.007 U, respectively. An increase on the hydroxyl groups at the fiber surface of 25% for diacetate and 317% for triacetate, after a 24 h treatment, is estimated by an indirect...

The vital staining properties of rose cultures (Rosa cv Paul's Scarlet) of increasing age were compared with their ability to be subcultured. At 4-day intervals beginning on day 14, after cell division and expansion had stopped, cells were stained separately with Evans blue, fluorescein diacetate, and phenosafranine. The degree to which parent cultures stained with each of these dyes was compar...

In the title compound, [Cd(C(10)H(8)O(6))(C(10)H(8)N(2))(H(2)O)(2)](n), the Cd(II) ion has inversion symmetry and is coordinated by O atoms from two water mol-ecules and two bridging 2,2'-(μ-p-phenyl-enedi-oxy)diacetate ligands and two N atoms from two 4,4'-bipyridine ligands, giving a slightly distorted octa-hedral geometry. The diacetate and 4,4'-bipyridine ligands also lie across inversion c...

A simple, selective and precise stabilityindicating HPLC method for determination of glabridin diacetate and dihexanoate prodrugs was developed, validated and applied to the enzymatic and chemical hydrolysis studies. The chromatographic separation was achieved on a reverse phase C18 (Thermo Hypersil-Keystone, 250 × 4.6 mm, 5 micron) column using the mixture of acetonitrile and water as mobile p...

The antilisterial activity of sodium diacetate and pediocin (ALTA 2341) on frankfurters was evaluated in combination with hydrodynamic pressure processing (HDP). Minimum inhibitory concentration (MIC) of these strains as determined in tryptic soy broth was 0.4% and >600 AU/mL, for sodium diacetate and ALTA 2341, respectively. Frankfurters were surface inoculated with a five-strain mixture of Li...
