The main aims of the study were: (1) to reveal age patterns female sex hormone levels (17-β-estradiol, progesterone), quantitative ultrasound parameters (broadband attenuation, speed sound) and body composition components (fat-free mass, lean muscle bone mineral content, fat mass visceral area) in women aged 7 80 years; (2) define normal ranges for IBL 17-β-estradiol progesterone kits girls und...

Objective(s) The effect of tamoxifen as a selective estrogen receptor modulator which is widely used for treatment of early and metastatic breast cancer was investigated on the folliculogenesis in rat's fetuses and neonates. Materials and Methods The pregnant rats assigned into test and control groups. Control group received olive oil and treatment groups received either 17-β-estradiol (10 µ...

The placenta is the exchange organ between the mother and the fetus. The inadequate function of this organ is associated with a number of pregnancy disorders. Hypoxia and oxidative stress during placental development may induce endothelial dysfunction, resulting in the reduction in the perfusion of the placenta. During pregnancy, the levels of estrogen are increased. Decreased estrogen levels h...

Type 2 diabetes causes structural and functional changes in the myocardium, which is called cardiomyopathy. Diabetic cardiomyopathy (DCM) is a distinct primary disorder process, independent of coronary artery disease, which leads to heart failure in diabetic patients. Also, DCM is a multifaceted disorder that is one of the leading causes of death in elderly and postmenopausal women. Menopause i...

Aims Test the putative contribution of 17-β-estradiol in the development of spreading depression (SD) events and head pain in awake, non-restrained rats. Main Methods Female, Sprague-Dawley rats were intact or underwent ovariectomy followed one week later by surgery to place electrodes onto the dura to detect epidural electroencephalographic activity (dEEG). dEEG activity was recorded two day...

Expression of concern for ‘Solar-driven photodegradation 17-β-estradiol and ciprofloxacin from waste water CO 2 conversion using sustainable coal-char/polymeric-g-C 3 N 4 /RGO metal-free nano-hybrids’ by Amit Kumar et al. , New J. Chem. 2017, 41 10208–10224, https://doi.org/10.1039/C7NJ01580A.

Isoflavones are phytoestrogens which have estrogen-like activity in animals and humans with structure similar to 17-β-estradiol and capable of binding to estrogen receptors (ERs).This experiment was conducted to demonstrate the effect of isoflavones on estradiol concentration in blood and its influence on the productive performances in ISA Brown laying hens fed with supplemented feed with large...

This study was conducted to evaluate the effect of soy milk on serum 17- β estradiol level and number of neurons in cerebral cortex and hippocampus as well as determination of the ratio of neurons in cortical and hippocampal regions in neonatal ovariectomized rats. Thirty female rats (one day old) were divided into six groups of five. At day 7, ovariectomy surgery was performed in four groups a...
