 Menopause is defined by its relationship to menstruation––it the cessation of menstruation. Medical texts identify menopause as part cycle “decay” associated with female reproductive functions; early often a dreaded result various medical treatments and sign disfunction.
 It turns out that only three types animals experience menopause: killer whales, short-finned pilot humans, while...
Estrogen receptor(s) (ER), progesterone receptor(s) (PGR), androgen receptor(s) (ANR), and prolactin receptor(s) (PRLR) were measured in N-nitrosomethylurea-induced mammary tumors in intact female Sprague-Dawley rats and in rats 9 days after ovariectomy. Following ovariectomy, 12 of 15 tumors regressed to 47.7 +/- 5.5% of the original size (hormone-dependent tumors), while the remaining three h...
Genetic factors play an important role in determining bone mineral density (BMD) in later life, with the genetic influence mediated through effects on both peak mass and on age- and menopause-related bone loss. At menopause there is an increase in the production and activity of various cytokines and growth factors within the bone microenvironment. The activity of interleukin-1 (IL-1), a powerfu...
We have used 31P-nuclear magnetic resonance spectroscopy to detect the metabolic changes that occur in estrogen-sensitive, N-methyl-N-nitrosourea-induced rat mammary tumors as they regress following ovariectomy. In untreated animals the spectra of the tumors showed a steady loss of high energy phosphates (phosphocreatine and nucleoside triphosphates) and an increase in inorganic phosphate. This...
conclusions the majority of iranian women had neutral attitudes towards menopause, which may be evidence of poor knowledge about menopause. therefore, it is suggested that appropriate educational programs be developed and implemented by policymakers in order to increase knowledge and raise awareness among women about menopause. results out of the 21 selected documents, 11 studies were eligible ...
background: the contribution of neuroinflammation in alzheimer’s disease (ad) has been widely reported. the effects of female gonadal hormones in both neuroinflammation and brain cognitive functions have also been well considered. objectives: in the present study, the possible protective role for endogenous ovarian hormones against learning and memory impairment as well as brain tissues oxidati...
objective(s): parkinson's disease (pd) is a progressive neurological disorder associated with motor disabilities and cognitive dysfunction as well. evidence indicates that pd occurs less frequently in women than men, confirming a role for steroid hormones in protection of dopaminergic nigrostriatal neurons. it is reported that soy genistein, an estrogen agonist phytoestrogen, display neuro...
introduction: several studies indicate that estrogen use increase performance on some tests of cognition especially in postmenopausal women. these steroids have many side effects, thus, other estrogenic agents with fewer side effects are needed to develop alternative treatment strategies. the main objection of this study was to evaluate the effects of different doses of dietary soy meals (with ...
Postmenopausal women as well as rodents after ovariectomy, which results in a lack of estrogen, can become obese. Ovariectomy-induced obesity in mice is associated with a decrease in oxygen consumption, indicating repressed energy expenditure. In this study, to elucidate the mechanism of weight gain after ovariectomy, we examined the expression patterns of genes related to energy expenditure an...
background: sexual instinct which is the cause of numerous changes in an individual’s life could be influenced by different factors such as menopause and ageing. this study was designed to compare sexual dysfunction before and after menopause. materials and methods: this was a cross-sectional study. participants were 174 menopausal women who referred to medical health centers of isfahan, iran. ...
