The separation of natural estrogens by countercurrent distribution.
The development of fluorometric methods (l-4) for the quantitative estimation of estrogens in the small quantities present in human urine has opened the way for improvements in the procedures utilized for the extraction and separation of these compounds. A study of the partition coefficients of estrone, estradiol-178,’ and estriol in various solvent systems has been of great value in the develo...

متن کاملCountercurrent Separation of Natural Products: An Update
This work assesses the current instrumentation, method development, and applications in countercurrent chromatography (CCC) and centrifugal partition chromatography (CPC), collectively referred to as countercurrent separation (CCS). The article provides a critical review of the CCS literature from 2007 since our last review (J. Nat. Prod. 2008, 71, 1489-1508), with a special emphasis on the app...
متن کاملMarginal Analysis of A Population-Based Genetic Association Study of Quantitative Traits with Incomplete Longitudinal Data
A common study to investigate gene-environment interaction is designed to be longitudinal and population-based. Data arising from longitudinal association studies often contain missing responses. Naive analysis without taking missingness into account may produce invalid inference, especially when the missing data mechanism depends on the response process. To address this issue in the ana...
متن کاملCountercurrent-distribution studies on histones.
1. The possibilities of fractionating histones and histone fractions by means of countercurrent distribution between two phases formed by water and butan-2-ol, in the presence of various concentrations of trichloroacetic acid, have been examined. 2. Although the principal histone fractions differ considerably in their partition ratios, a satisfactory resolution of the principal histone fraction...
