Enhanced estrogenic effects of biotransformed soy extracts

This study aimed to improve the process conditions for biotransformation of soymilk polyphenols by tannase to obtain higher amounts of isoflavone aglycones and metabolites such as equol. The estrogenic potential of the extracts was evaluated in in vitro assays. The results showed that the aglycones increased 36–46 times after reaction with tannase and proved that it is possible to produce equol in soymilk using an enzymatic bioprocess, without gut microbial intervention. Moreover, the soymilk biotransformed by tannase presented higher estrogenic action in the MCF-7 BUS cell line assay, making it a promising nutraceutical with possible effects in the attenuation or treatment of menopause symptoms.Graphical abstract

Our panel this morning discussed the issues surrounding how the WHI results were interpreted and communicated to women and their health care providers. We recognize that hormones are not appropriate for all women, and look forward to hosting a future panel that highlights alternatives. The speakers have a variety of backgrounds and experiences (and genders), and we aim to promote diversity of voices. This was not normal breakfast conversation. Today was a jolting – and disruptive – talk about what happens to women’s bodies when they age. (Who knew that if you’re menopausal and you don’t take y...

Sex Differences in the Vascular Function and Related Mechanisms: Role of 17βEstradiol. Am J Physiol Heart Circ Physiol. 2018 Sep 07;: Authors: Pabbidi MR, Kuppusamy M, Didion SP, Sanapureddy P, Reed J, Sontakke SP Abstract The incidence of cardiovascular disease (CVD) is lower in pre-menopausal women but increases with age and menopause compared to similar-aged men. Based on the prevalence of CVD in the post-menopausal women, sex hormone-dependent mechanisms have been postulated to be the primary factors responsible for the protection from CVD in pre-menopausal women. Recent Women's Health Initia...

(Natural News) For women suffering from the unpleasant symptoms that precede menopause, traditional Chinese medicine (TCM) may present a superior alternative to the standard hormone replacement therapy. Recent research suggests that regular intake of Kuntai capsules (KC) is more effective at alleviating perimenopausal syndrome than HRT, reported a ScienceDirect review. Perimenopausal syndrome is triggered by decreasing amounts of sex...

Abstract We explored the strategy of frozen-thawed embryo transfer (FET) in the women with advanced maternal age (AMA). We first determined the age cut-off point of AMA by retrospective analysis of pregnancy outcomes in the patients undergoing FET. The patients with AMA were divided into 3 groups including natural cycle (NC) group, controlled ovarian stimulation (COS) group, and hormone replacement therapy (HRT) group, and simultaneously were divided into 2 groups including cleavage-stage embryo transfer (CET) group and blastocyst-stage embryo transfer (BET) group. The clinical pregnancy, embryo implantation, abor...
