Pressure influence of capacity factorThe pressure applied in liquid chromatography (LC) can influence the capacity factor of analytes. Using commercial equipment, column (33脳4.6 mm) and 1.5 渭m non-porous, tetradecyl (C 14 ) coated silica particles, a moderate but significant change in the ...
The aim of the present study was to characterize the phenolic acids, flavonoids, and antioxidant properties of monofloral honey collected from five different districts in Bangladesh. A new high performance liquid chromatography (HPLC) equipped with a UV detector method was developed for the identificat...
For general nanofluidic analysis, the fact that a pressure-driven flow does not limit the choice of solvents (aqueous or organic) is an important aspect. In this paper, an automated injection system using a pressure-driven flow for several hundred nanometer-sized channels (extended nanochannels) ...
The role of the redox potential as a factor contributing to the NO-generating activity of these two proteins is evaluated. The results show that LtHb undergoes the same reactions as HbA and that the reduced efficacy for these reactions for LtHb relative to HbA is consistent with the much ...
Peaks were subsequently integrated via ChromSpace's proprietary deconvolution algorithm, wherein co-eluting peaks can be resolved on the basis of mass spectra. Integrated peaks were identified via comparison with the NIST20 library with a threshold match factor of 800, and the average peak area ...
ABTS+•; Ablankrepresents the maximum absorbency, measured at end-point addition after addition of an established volume of solvent (μl, same as Trolox volume) in a cell containing ABTS+•;fis the dilution factor of the sample; and CTroloxis theeffective concentrationof Trolox, in μmol...

This paper is concerned with the problem of obtaining phosporamidic derivatives by an original synthesis, the compound separation by HPLC, founding molecular descriptors and their correlation for mathematical description of parameters that influence the capacity factor.Maranescu...
wherein the composite media has a size exclusion limit of about 500 Daltons to about 2,000,000 Daltons and provides a value of a flux enhancement factor E greater than about 3, as determined by the equation ##EQU21## in which Dsis the experimentally measured effective intraparticle...
IL-10 was first described as a cytokine synthesis inhibitory factor (CSIF) produced by Th2 cells which inhibited production of proinflammatory cytokines such as interferon-gamma (IFN-γ), interleukin-1-alpha (IL-1α), interleukin-1-beta (IL-1β), interleukin-2 (IL-2) and tumor necrosis ...
