Comparison of the antioxidant effects of equine estrogens, red wine components, vitamin E, and probucol on low-density lipoprotein oxidation in postmenopausal women.

Objective: Oxidized low-density lipoprotein (LDL) seems to play an important role in the etiology of atherosclerosis. To further study this, we performed two studies: (1) we determined the ability of 10 estrogen components of the drug, conjugated equine estrogen (CEE), trans-resveratrol (t-resveratrol) and quercetin (red wine components), trolox (vitamin E analog), and probucol (a serum cholesterol-lowering drug) to delay or prevent the oxidation of plasma LDL isolated from untreated postmenopausal women, and (2) we assessed the effect of long-term (>1 year) estrogen replacement therapy and hormone replacement therapy on LDL oxidation by ex vivo methods.

Design: For the in vivo study, three groups of postmenopausal women were selected based on whether they were on long-term CEE therapy (group A: 0.

Successful salvage of relapsed high-risk gestational trophoblastic neoplasia patients using a novel paclitaxel-containing doublet.

Objective: To describe one institution's results with a novel 3-drug doublet, consisting of paclitaxel, etoposide and cisplatin, for salvage of relapsed high-risk gestational trophoblastic neoplasia (GTN) patients.

Study Design: Analysis of treatment results with the doublet regimen in two patients with recurrent/persistent high-risk choriocarcinoma in the Division of Gynecologic Oncology, Toronto-Sunnybrook Regional Cancer Centre, University of Toronto. Both patients had been treated previously with one or more of the doublet drugs.

What is the best regimen for low-risk gestational trophoblastic neoplasia? A review.

A review of published and unpublished material was performed using medical databases, bibliographies and personal contact with peer experts to determine the best treatment of low-risk gestational trophoblastic neoplasia (GTN). Thirty-nine studies contained the minimum information required for inclusion in this study. Additional reports were retrieved but could not be disaggregated with sufficient accuracy to obtain valid comparative information.

Potential role of the interaction between equine estrogens, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) in the prevention of coronary heart and neurodegenerative diseases in postmenopausal women.

Background: An inverse relationship between the level of high-density lipoprotein (HDL) and coronary heart disease (CHD) has been reported. In contrast, oxidized HDL (oHDL) has been shown to induce neuronal death and may play an important role in the pathogenesis of CHD. In the present study we have investigated a: the effect of various equine estrogens on HDL oxidation, b: the inhibition of LDL oxidation by HDL and c: the effect of these estrogens on LDL oxidation in the presence of HDL.

Pharmacokinetics of 17 beta-dihydroequilin sulfate in normal postmenopausal women under steady state conditions.

Objective: In the present study, the constant infusion of [3H]17 beta-dihydroequilin sulfate ([3H]17 beta-EqS) was used to estimate the metabolic clearance rate (MCR) of 17 beta-dihydroequilin sulfate (17 beta-EqS) and to measure the conversion of this estrogen to equilin sulfate (EqS), equilenin sulfate (EqnS), 17 beta-dihydroequilenin sulfate (17 beta-EqnS), equilin (Eq), equilenin (Eqn), 17 beta-dihydroequilin (17 beta-Eq), and 17 beta-dihydroequilenin (17 beta-Eqn) in normal postmenopausal women.

Methods: In seven healthy postmenopausal women, infusion of [3H]17 beta-EqS was started 30 minutes after a priming dose and continued at a constant rate of 10-20 microCi/hour, for 3-6 hours. Three blood samples were taken during and at the end of infusion.
