Example sentences for: phytoestrogens

How can you use “phytoestrogens” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • In this regard, it is known that the hormonal action of estrogens may be mediated by the differential expression of estrogen receptors alpha vs betta in brain structures that activate or inhibit cell death mechanisms [ 56 ] . Although, this parameter was not directly investigated in this study, the differing influence that dietary phytoestrogens had on CALB (significant decrease) and COX-2 (significant increase) in the male frontal cortex, suggests that phytoestrogens may activate programmed cell death.

  • Additionally, one of our laboratories has quantified phytoestrogen plasma levels in a variety of physiologic conditions validating the importance of soy-derived phytoestrogens via rodent chow diets [ 36 ] . Therefore not all diets have the same phytoestrogen levels, however, all diets, which have soy as their main protein source, contain phytoestrogens.

  • The design of this study was to examine the influence of phytoestrogens (present via soy in rodent diets) on VSM in three separate experiments utilizing radial arm maze methods to examine varying aspects of memory.

  • However, brain aromatase and circulating plasma estradiol levels in male rats does not appear to be influenced by dietary phytoestrogens [ 22 41 51 ] . As the results from this research imply, phytoestrogens have considerable effects on hormonally sensitive parameters and their influence may be, in part, responsible for many reported sexual dimorphisms such as, the establishment and plasticity of sexually dimorphic brain structures like the sexually dimorphic nucleus of the preoptic area (SDN-POA) and the anteroventral periventricular nucleus (AVPV) [ 40 41 ] .

  • Phyto-free males) and the greater affinity of phytoestrogens is for ER-β > ER-α, it has been shown that estrogen-related neuronal apoptosis is determined by ER-β and the Fas/Fas ligand system [ 57 ] . In fact isoflavones have been shown to cause apoptosis in rat primary cortical neurons in vitro via a calcium dependant mechanism [ 58 ] . Furthermore, the action of phytoestrogens may be tissue site specific.
