The investigators found also that, in contrast with CIMT, cardiac computed tomography (CT) measures of atherosclerosis did not differ significantly between the estradiol
and placebo groups, regardless of age.
In a subgroup analysis of postmenopausal women with heart failure, investigators found a significant positive association with the testosterone to estradiol
ratio (HR, 1.65; 95% CI, 1.07-2.54) and inverse associations for estradiol
(HR, 0.60; 95% CI, 0.39-0.93) and for dehydroepiandrosterone (HR, 0.59; 95% CI, 0.44-0.78).
At first, we found that female rats had few testosterone [Figure 4]a and male rat also showed low amount of estradiol
[Figure 4]b as expected, and there were no difference among stressed animals, unstressed control and those in adaption no matter in testosterone [Figure 4]a or estradiol
There appears to be a paucity of data in humans describing the role of estradiol
and/or ER activation relative to the expression of genes targeted by ER signaling which are known to play a role in the myogenic activation of satellite cells.
This cell line was derived from a human choriocarcinoma, and it retained the higher capacity to produce estradiol
when an exogenous DHEA was provided .
Concentrations of progesterone and estradiol
in 25-50 [mu]l of plasma were determined in duplicate without extraction by using commercial RIA kits from DSL Laboratories Inc.
The ex vivo resuscitated group, gives direct information about the cardioprotective effects of the treatment with estradiol
outside the body, away from any endocrine, neural and other inflammatory pathways interference.
Also, after removing the treatment, 60 blood samples were obtained for determining estradiol
levels; five samples were obtained from each specimen with intervals of five days between samples for causing no harm to the animals by the punctures needed for getting the blood.
stream by converting it into estradiol
through aromatase in adipocytes.
Progesterone (Sigma-Aldrich, Brazil) and estradiol
benzoate (Sigma-Aldrich) were dissolved in an oil vehicle at concentrations of 0.5 and 0.05 mg/mL, respectively.
On the other hand, treatments with eCG can affect ovarian endocrine function and lead to an obvious increase in estradiol
productions (Liu et al., 2007).
and BPS each increased cell proliferation, but following exposure to both compounds there were fewer cells than in control cultures.
