We present a method for the determination of the isoflavan equol in plasma and urine. This estrogenic isoflavan, which is formed by the action of the intestinal microflora, may have higher biological activity than its precursor daidzein. High urinary

We present a method for the determination of the phytoestrogen metabolite O -desmethylangolensin ( O -DMA) in plasma (serum) and in urine. O -DMA is a metabolite of daidzein, which occurs in soybeans. It has been suggested that isoflavones may afford

The overall net photosynthesis potential of Diapensia lapponica was very low. It was highest at the end of August (11.1 μmol CO 2 (μmol chlorophyll) −1 hr −1 ) and decreased during the autumn and winter, reaching a minimum in February (0.6 μmo

A simple competitive time-resolved fluoroimmunoassay was developed for the analysis of the boar taint steroid 5α-androst-16-en-3-one in serum and fat samples. Sensitivities of 30 ng/g and 0.8 ng/mL were obtained for fat and serum measurements, and t

A simple and efficient method of derivatizing and labeling the terminal sugar ring of digoxin (and other steroid glycosides) is described. The terminal sugar ring was oxidized by periodate to dialdehyde, followed by a reaction with the aminooxy group

Two different kinds of europium(III) chelates, luminescent and nonluminescent, were prepared. The chelates were coupled to bioanalytical reagents, such as antibodies, after activations of the amino group on the chelates with thiophosgene,2,4,6-trichl
