Isoflavones and cardiovascular disease
2010
The specific profile of estrogens on cardiovascular risk, with limiting action on atherogenesis but a less clear protection on cardiovascular episodes, might be improved by other agonists of the estrogen receptor, such as isoflavones. By using a systematic search based on the electronic Medline database plus a hand-search of reference lists of selected review papers, we reviewed the rapidly growing body of experimental and clinical data that, on average, follow a pattern of benefit rather similar to estrogens. Experimental models have used endothelial and vascular smooth muscle cells, isolated arteries, and live animals, including monkeys. The clinical evidence arises from studies on the li…
Soy-derived phytoestrogens as preventive and acute neuroprotectors in experimental ischemic stroke: Influence of rat strain
2011
The ability of a soy-based high-phytoestrogen diet (nutritional intervention) or genistein (pharmacological intervention), to limit ischemic brain damage in Wistar, Wistar-Kyoto (WKY) and spontaneously hypertensive (SHR) rats, has been assessed. As to the nutritional intervention, two groups from each strain received either a phytoestrogen-free (PE-0) or a high-phytoestrogen (PE-600) diet from weaning to adulthood. As to the pharmacological intervention, all animals were fed the standard soy-free AIN-93G diet and subsequently separated into two groups from each strain to receive either pure genistein (aglycone form, 1mg/kg/day intraperitoneal) or vehicle at 30 min reperfusion. After an epis…
Effects of ipriflavone on bone mass and calcium metabolism in postmenopausal osteoporosis.
1992
Recently it has been demonstrated that ipriflavone (IP), an isoflavone derivative, is able to increase bone mass in patients with established postmenopausal osteoporosis (PMO). Here we present a preliminary report of a 2-year multicenter, double-blind, placebo-controlled clinical study performed in order to evaluate the efficacy and tolerability of IP in PMO. A large number of patients with PMO, referred to 12 Italian centers, was randomly divided into 2 groups and treated with oral IP (600 mg/day) or placebo (Pl). All patients received an oral Ca supplement (1 g/day). One hundred and twenty six patients completed 1 year of the study. Bone mineral density (BMD) of the distal radius, measure…
Bisphenol A Effects on the Growing Mouse Oocyte Are Influenced by Diet1
2009
Growing evidence suggests that exposure to bisphenol A (BPA) has the ability to disrupt several different stages of oocyte development. To date, most attention has focused on the effects of BPA on the periovulatory oocyte, and considerable variation is evident in the results of these studies. In our own laboratory, variation in the results of BPA studies conducted at different times appeared to correlate with changes in mill dates of animal feed. This observation, coupled with reports by others that dietary estrogens in feed are a confounding variable in studies of endocrine-disrupting chemicals, prompted us to evaluate the effect of diet on the results of BPA studies of the periovulatory o…
