EXCRETION OF THE LIGNANS ENTEROLACTONE AND ENTERODIOL AND OF EQUOL IN OMNIVOROUS AND VEGETARIAN POSTMENOPAUSAL WOMEN AND IN WOMEN WITH BREAST CANCER
Dietary studies and assays of urinary lignans in postmenopausal women showed that lignan excretion is significantly lower in urine of women with breast cancer than in normal omnivorous and vegetarianExpand
Reversed-phase C18 cartridge for extraction of estrogens from urine and plasma.
TLDR
A simple method for extraction of estrogens that is efficient over the whole polarity range of estrogen metabolites in urine and plasma is described and the recoveries of added 3H-labeled estrogens are essentially quantitative. Expand
Use of hypnosis in studies of the effect of stress on cardiovascular function and hormones.
TLDR
In the present study, mental stress had a depressing effect, if any, on plasma prolactin, and Hypnosis in itself has no effect on plasma hormones in unstressed subjects compared to the normal diurnal variations. Expand
Serum markers for breast cancer.
A considerable number of tumour markers and other laboratory tests are used for follow up and evaluation of breast cancer patients. No marker presently available is sensitive enough for earlyExpand
Identification of the isoflavonic phytoestrogen daidzein in human urine.
TLDR
The identification by gas chromatography-mass spectrometry of the isoflavonic phytoestrogen daidzein for the first time in human urine is described and the metabolism and effect on reproduction of is oflavones in animals and the possible significance of phy toestrogens in man is discussed. Expand
Selective chromatographic fractionation of catechol estrogens on anion exchangers in borate form.
TLDR
The borate form of QAE-Sephadex A-25 was capable of separating estrogens not possessing vicinal cis-hydroxyls from the corresponding neutral steroids and Quantitative recovery of catechol estrogens was thereby obtained without use of antioxidants. Expand
5. Analytical methods: physiochemical assays. Use of ion exchange chromatography in steroid analysis.
TLDR
The high capacity and flexibility of IXC has made it a technique of choice in the purification of biological samples for the multicomponent analysis of steroids by GC or GC-MS during the last decade. Expand
Capillary gas chromatographic method for the analysis of lignans in human urine.
TLDR
A capillary column gas chromatographic (GC) method for the analysis of lignans in urine and some values for the excretion of theseLignans by normal men and women are presented. Expand
Diet and urinary excretion of lignans in female subjects.
TLDR
The influence of diet on the biosynthesis of this new group of compounds was investigated by comparing the urinary excretion of the principal lignan, trans-2,3-bis-(3-hydroxybenzyl) -butyrolactone (enterolactone, HBBL), in 12 omnivoric and 14 vegetarian women. Expand
Improved Laboratory Test Selection and Enhanced Perception of Test Results as Tools for Cost-Effective Medicine
TLDR
This review addresses preferred methods to improve laboratory test selection, and examines methods that more effectively convey laboratory results to clinicians, and discusses application of expert systems to provide rules based on knowledge and experience to analyze results of tests and suggest diagnosis and action.
