Aging is associated with visceral adiposity, metabolic disorders, and chronic low-grade inflammation. 17α-estradiol (17α-E2), a naturally occurring enantiomer of 17β-estradiol (17β-E2), extends life span in male mice through unresolved mechanisms. We tested whether 17α-E2 could alleviate age-related metabolic dysfunction and inflammation. 17α-E2 reduced body mass, visceral adiposity, and ectopi...

Two experiments were conducted at three locations to determine the correct dosage and carrier for trenbolone acetate (TBA) and estradiol (E2) implants in feedlot steers. In the dose-response experiment, 1,296 steers were allotted to six implant treatments (48 pens per location): control, 140 mg of TBA (140/0), 30 mg of E2 (0/30), 20 mg of TBA + 4 mg of E2(20/4), 80 mg of TBA + 16 mg of E2(80/16...

Estradiol (E2) has been shown to exert organizational, neurotrophic, and neuroprotective effects in the CNS. The present study assessed the specificity of the neuroprotective effects of estradiol for the potent 17b-isomer. SK-N-SH cells from a human neuroblastoma cell line, which we have shown to be estrogen-responsive, were cultured at low or high plating density. Then cells were exposed to 17...

The impact of estrogen on brain function, especially in individuals with diabetes, remains uncertain. This study aims to compare cerebral glucose metabolism levels intact rats, ovariectomized (OVX) and 17β-estradiol (E2)-treated OVX diabetic female rats. Sixteen rats were administered a single intraperitoneal injection 70 mg/kg streptozotocin (STZ) induce diabetes (intact, n = 6; OVX, OVX+E2-tr...

The behavior of natural estrogens was examined by separately spiking 17β-estradiol (E2) and estrone (E1) into semicontinuous activated sludge reactors operated under aerobic, anaerobic and sequential anaerobic/aerobic conditions. Under aerobic and anaerobic conditions, E1 was formed from E2. The conversion of E1 to E2 was maximum conversion of E2 to E1 was higher than t E1 to E2. Overall, the d...

Estrogens at physiological concentrations are thought to play an immune-stimulating role, whereas androgens have an antiinflammatory impact. However, their role on cytokine secretion in the presence or absence of cortisol has not been investigated. Furthermore, the role of hydroxylated estrogens downstream of 17 -estradiol (E2) on secretion of tumor necrosis factor (TNF) is not known. In this s...

Estrogen influences the development and function of the nervous system through estrogen receptor-dependent changes in gene expression and by rapidly influencing diverse intracellular signaling pathways. We have investigated the influence of estradiol on developing neonatal rat cerebellar neurons in primary culture and found that low concentrations of 17beta-estradiol (17beta-E2), 17alpha-E2, 17...

Objective: Although, earlier studies have evaluated the significance of various estradiol patterns during controlled ovarian hyperstimulation (COH), their prognostic significance remains unclear. The objective of this study is to investigate the rate of increase in estradiol (ROI-E2) during COH and evaluate it as a predictor of ovarian response. Materials and Methods: In this retrospective stud...

background: estrogens include estoril (e3), estradiol and estrone (e1). these chemicals are produced in human and animal bodies as well as in synthetic chemicals (drugs). estrogens can enter water sources in different ways. when these chemicals enter the human body through water and wastewater, they have the ability to mimic or disrupt the normal estrogen activities in humans and animals. estro...

The current study was undertaken to determine the 17-β Estradiol (E2) and Progesterone (P4) levels in different milk products some baby follow-on samples collected from retail markets Türkiye. For this purpose, a total of 50 8 product groups with fat levels, production technologies, series were analyzed for natural P4 E2 using commercial ELISA kit. highest level determined UHT whole (3%) (39.20...
