Skin aging is a process influenced by several factors, including estrogen. Estrogen modulates the physiology of skin, and its deficiency in postmenopausal women accelerates skin aging. Administration estrogen can delay process. Phytoestrogens are estrogen-like compounds derived from plants that administered via oral as well astopical routes. Trigonella foenum-graecum, commonly known fenugreek, ...
In early postmenopausal women, estrogen withdrawal is associated with increased bone turnover leading to bone loss and increased risk of fracture. Recent studies have suggested that the remaining bone tissue is significantly stronger, stiffer and has an increased tissue-level mineral content. Such changes may occur to compensate for bone loss or as a direct result of estrogen deficiency. To dat...
BACKGROUND Postmenopausal estrogen deficiency is associated with an increased cardiovascular risk, hypertension, and oxidative stress. Angiotensin type 1 (AT(1)) receptor regulation is involved in the pathogenesis of atherosclerosis. To characterize vascular function, oxidative stress, and AT(1) receptor regulation during estrogen deficiency, ovariectomized spontaneously hypertensive rats (SHR)...
introduction: primary ovarian failure (pof) is a syndrome composed of amenorrhea, estrogen deficiency and follicular stimulating hormone (fsh) of menopausal ranges in young women. in this article, we report a case of primary amenorrhea that presented with full term pregnancy.case presentation: a 29-year old woman with a history of primary amenorrhea attended hospital with full term pregnancy. s...
In women, estrogen deficiency after menopause frequently accelerates osteoclastic bone resorption, leading to osteoporosis, the most common skeletal disorder. However, mechanisms underlying osteoporosis resulting from estrogen deficiency remain largely unknown. Here we show that in bone-resorbing osteoclasts, estrogen-dependent destabilization of hypoxia-inducible factor 1 alpha (HIF1α), which ...
Estrogen and iron deficiency regulate the synthesis of transferrin in chick liver by causing a specific increase in transcription of the transferrin gene. The relative rate of synthesis of transferrin mRNA was measured by allowing isolated nuclei to continue transcription in vitro in the presence of [CU-~~P]UTP. The 32P transcripts then were hybridized to immobilized recombinant DNA containing ...

Perimenopause is a period in woman’s life characterized by estrogen deficiency, leading to atrophic changes the reproductive system, which are directly correlated with incidence of cervical cancer. Using example this case report, we would like demonstrate that competent examination helps verify diagnosis, before using laboratory and instrumental diagnostic methods
