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...

Hydrochloric acid and/or sodium hydroxide may be used during manufacture to adjust pH of suspension to approximately 6. Triamcinolone diacetate is practically insoluble in water; soluble in chloroform; sparingly soluble in alcohol and in methanol; and slightly soluble in ether. This preparation is suitable for parenteral administration through a 23-gauge needle (or larger), but NOT suitable for...

Dithranol was introduced into anti-psoriatic therapy in 1916, but the principle of its activity remains unkown with regard to the quantitative aspects of its efficacy e.g. in enzyme inhibition, D N A interaction and interference with lipid metabolism. In vitro experiments have indicated that dithranol irreversibly inhibits glucose-6-phosphate-dehydrogenase (EC 1.1.1.49) [10] and the incorporati...

A modified Gompertz equation was used to model the effects of temperature (55, 60, and 65 degrees C), sodium lactate (0, 2.4, and 4.8%), and sodium diacetate (0, 0.125, and 0.25%) on inactivation of Listeria monocytogenes strain MFS 102 (serotype 4b) in frankfurter slurry. The effects of these factors were determined on the shouldering region (parameter A), maximum death rate (parameter B), and...

The title compound, C(12)H(14)O(6), was prepared by the Williamson reaction of 1,4-dihydroxy-benzene and methyl chloro-acetate with phase-transfer catalysis. The compound lies on an inversion center. The structure is stabilized by weak C-H⋯π inter-actions.

In the title compound, C(14)H(18)O(6), a crystallographic center at the centroid of the aromatic ring generates the complete mol-ecule which is planar within 0.085 (1) Å for the non-H atoms. In the crystal, weak C-H⋯O and C-H⋯π inter-actions link the molecules.

A new eunicellin diterpenoid, cladieunicellin I (1), and a new natural eunicellin, litophynin I diacetate (2), were isolated from a Formosan soft coral identified as Cladiella sp. The structures of eunicellins 1 and 2 were elucidated by spectroscopic methods and by comparison of the spectral data with those of related analogues. Eunicellin 1 exhibited significant cytotoxicity toward the DLD-1 h...

The centrosymmetric title compound, C(18)H(26)O(4), was prepared in high yield from 4-acetoxy-styrene via Ru-catalysed homo-olefin metathesis. Exclusive formation of the E-configurated isomer was observed. In the crystal, a strong C-H⋯π inter-molecular inter-action links the mol-ecules together.
