Unilateral nevoid telangiectasia syndrome (UNTS) can be classified into two major categories: congenital and acquired. There have been reports showing an increase in skin estrogen and progesterone receptors in patients with this syndrome. We report a male patient with acquired unilateral nevoid telangiectasia syndrome without any associated physiological or pathological conditions.<...

In 1931, estrogen was originally discovered as a female sex hormone by Marrian and Butenandt (1931). Estrogen is responsible for maintaining female reproductive organs and functions. Beyond the effects on reproductive organs, the neuroprotective activities of estrogen have been identified by Simpkins et al. (1994) and thereafter by numerous other researchers (Viscoli et al., 2001). The simple c...

bisphenol-a (bpa) is an industrial xenoestrogen used widely in our living environment. recently, several studies suggested that bpa has destructive effects on dna and chromosomes in normal body cells via estrogen receptors (er). therefore, bpa could be considered as an important mediator in many diseases such as cancer. however, there are still many controversial issues which need clarification...

Sex differences showing a lower prevalence and better outcome after ischemic stroke in women have been described, differences that are abrogated by natural or surgical menopause.1,2 High levels of endogenous estrogens in premenopausal women have been associated with reduced risk for a number of diseases, such as hypertension, diabetes mellitus, obesity, vascular disease, and stroke.2 The growin...

Triple-negative breast cancer (TNBC) is considered one of the most aggressive forms with poor survival rates compared to other subtypes. TNBC characterized by absence estrogen receptor alpha, progesterone receptor, and human epidermal growth factor 2, limiting those viable treatment options available patients Furthermore, due particularly high heterogeneity TNBC, conventional treatments such as...

AT(2) receptors may act in opposition to and in balance with AT(1) receptors, their stimulation having beneficial effects. We found renal AT(2) receptor expression in female mice higher than in male mice. We asked the question of whether such expression might be estrogen dependent. In male, female, ovariectomized, and estrogen-treated ovariectomized mice, we studied renal AT(1) and AT(2) recept...

Background: Papillary thyroid carcinoma (PTC), occurs mostly in women and sex hormones may play a role in the pathogenesis and clinical course. The objective of this study was to determine the status and prevalence of estrogen and progesterone receptors in PTC with regard to age, gender, tumor size and lymph node involvement. Methods: Immunohistochemical stains were performed on 92 tissue bl...

UNLABELLED Larynx is extremely sensitive to endocrinologic changes. Most vocal fold mucosa alterations are caused by changes in vocal fold liquid content and its epithelial changes. Estrogen and progesterone interfere and change this liquid content in the vocal folds. Our goal with the present paper is to study the presence of estrogen and progesterone receptors on vocal fold epithelium in 19 v...
