Estrogens are important regulators of body physiology and have major effects on metabolism, bone, the immune- and central nervous systems. The specific mechanisms underlying the effects of estrogens on various cells, tissues and organs are unclear and ...

Background In pregnant rats, structural luteal regression takes place after parturition and is associated with cell death by apoptosis. We have recently shown that the hormonal environment is responsible for the fate of the corpora lutea (CL).

Improvement of Menopausal Symptoms by <i>Beta vulgaris</i>, <i>Artemisia princeps</i>, and <i>Eleutherococcus senticosus</i> via Estrogen Pathway Activation in MCF-7 Cells and OVX Mice. [PDF]
Plant extracts from Beta vulgaris (BK‐R) and Artemisia princeps (BK‐A) act as full estrogen‐mimetics, activating both ERα genomic and non‐genomic signaling in MCF‐7 cells and OVX mice. Across in vivo assays, BK‐R/BK‐A restored uterine structure, improved estrous cycling, preserved trabecular bone, and normalized serum E2/osteocalcin, approximating ...

Estrous behavior in dairy cows: identification of underlying mechanisms and gene functions [PDF]
Selection in dairy cattle for a higher milk yield has coincided with declined fertility. One of the factors is reduced expression of estrous behavior. Changes in systems that regulate the estrous behavior could be manifested by altered gene expression ...

Oestrogen, an evolutionary conserved regulator of T cell differentiation and immune tolerance in jawed vertebrates? [PDF]
In teleosts, as in mammals, the immune system is tightly regulated by sexual steroid hormones, such as oestrogens. We investigated the effects of 17β-oestradiol on the expression of several genes related to T cell development and resulting T cell ...

Influence of Ionophore Supplementation on Growth Performance, Dietary Energetics and Carcass Characteristics in Finishing Cattle during Period of Heat Stress. [PDF]
Forty-eight crossbred heifers (378.1±18 kg) were used in a 56-d feeding trial (four pens per treatment in a randomised complete block design) to evaluate the influence of ionophore supplementation on growth performance, dietary energetics and carcass ...

Morphological aspects of the squamocolumnar junction of rats in permanent estrus treated with an association of estrogen and glucocorticoid [PDF]
PURPOSE: to evaluate the effects of estradiol benzoate associated with dexamethasone on the squamocolumnar junction (SCJ) of rats in permanent estrus (PE) and then ovariectomized (Ovx).

Influence of Estradiol Benzoate on Fat Storage.
In a recent study Loeb and Burr1 showed that female rats store more body fat than males when maintained on a diet rich in saturated fat (hydrogenated coconut oil) but devoid of essential fatty acids. It then became a matter of interest to ascertain whether this finding could be attributed to the effect of estrogen on fat metabolism.

The abuse of synthetic esters of natural steroids such as testosterone and estradiol in cattle fattening and sports is hard to detect via routine urine testing. The esters are rapidly hydrolysed in vivo into substances which are also endogenously present
