OBJECTIVES Previous studies have reported that osteoporosis due to estrogen deficiency influences fracture healing. Transforming growth factor (TGF-b) has been found to be involved in fracture healing via the regulation of the differentiation and activation of osteoblasts and osteoclasts. The current study aimed to determine the effects of estrogen on the expression of TGF-β1 during fracture he...

Menopause is associated with an increase in blood pressure (BP) and a decrease in physiologic nocturnal BP fall. These factors may play a role in the increased risk of cardiovascular events after menopause. Some studies indicate that transdermal estrogen replacement therapy may help restore the 24-h BP profile, but data on the effect of oral conjugated estrogens are lacking. We compared 24-h am...

BACKGROUND Observational studies have reported less frequent carotid atherosclerosis in healthy women taking postmenopausal hormone therapy. Estrogen with progestin did not reduce peripheral arterial events among women with preexisting coronary heart disease. This analysis evaluates clinical peripheral arterial disease among generally healthy women in the Women's Health Initiative randomized tr...

BACKGROUND In separate Women's Health Initiative randomized trials, combined hormone therapy with estrogen plus progestin reduced colorectal cancer incidence but estrogen alone in women with hysterectomy did not. We now analyze features of the colorectal cancers that developed and examine the survival of women following colorectal cancer diagnosis in the latter trial. PARTICIPANTS AND METHODS...

BACKGROUND Postmenopausal estrogen use has been associated with reduced carotid atherosclerosis in observational studies, but this relationship has not been confirmed in a clinical trial. The impact of estrogen on atherosclerotic disease in other peripheral arteries is unknown. METHODS AND RESULTS Postmenopausal women with coronary heart disease (CHD) and an intact uterus (n=2763) were random...

BACKGROUND Considering the effect of preterm delivery in morbidity and mortality of newborns, its precaution and prevention is so important. OBJECTIVE To investigate the association between second trimester maternal serum biomarkers (Human Chorionic Gonadotropin, Alpha-fetoprotein, Non-conjugated estrogen, Inhibin A) and pre-term delivery. MATERIALS AND METHODS This is a historical cohort s...

OBJECTIVE To manage patients with dysfunctional uterine bleeding (DUB) according to endometrial thickness. METHODS A retrospective chart review of 49 patients who reported 8 or more days of bleeding was performed. They were then divided into three groups based on endometrial thickness (mm): less than 6, 6-11, and greater than 11. These three groups were treated with combined oral contraceptiv...

or quarterly cyclic hormone therapy (2 mg of estradiol on days 1-78 and 1 mg of estradiol on days 79-84, with 1 mg of norethindrone on days 69-78) was stopped after 2-3 years of the planned 5 years of treatment because of an unacceptably high rate of endometrial pathology (including one en-dometrial cancer) in the quarterly compared with the monthly cycle group (6.2% versus 0.8%; P ‫ס‬ .004). A...

STUDY DESIGN: Surgically postmenopausal adult female cynomolgus macaques (Macaca fascicularis) were given either no treatment (n = 26), conjugated equine estrogens (n = 22), or combined therapy with conjugated equine estrogens and medroxyprogesterone acetate (n = 21). Drugs were administered in the diet, at doses equivalent on a caloric basis to 0.625 mg per woman per day for conjugated equine ...

Phytoestrogens are polyphenolic non-steroidal plant compounds with estrogen like activity exerted through estrogen receptors. These receptors are distributed in several tissues such as male and female reproductive systems, bones, cardiovascular and central nervous systems. These natural phenolic compounds include isoflavonoids, flavonoids, lignans and stilbenes. Isoflavonoids are the most studi...
