The Effect of Estrogen Usage on Eccentric Exercise-Induced Damage in Rat Testes
Exercise Testis Estrogens Rats
2015/10/22
Background: Recent years, lots of scientific studies are focused on the possible mechanism of inflammatory response and oxidative stress which are the mechanism related with tissue damage and exercise...
Estrogen receptor involvement in the response of human keratinocytes to ultraviolet B irradiation
UVB Estrogen receptor Keratinocytes
2015/5/25
The signaling mechanisms involved in UVB-induced skin cancer are complex and although the scope of this work is inherently limited in focus, the findings may provide insight into how estrogen receptor...
Chemotherapy, estrogen, and cognition : neuroimaging and genetic variation
Chemotherapy estrogen cognition neuroimaging genetic variation
2015/5/21
The time course and biological mechanisms by which breast cancer (BC) and/or alterations in estrogen status lead to cognitive and brain changes remain unclear. The studies presented here use neuroimag...
Distribution of Type I Collagen Morphologies in Bone: Relation to Estrogen Depletion
AFM Ultrastructure disease diagnosis
2014/11/6
Bone is an amazing material evolved by nature to elegantly balance structural and metabolic needs in the body. Bone health is an integral part of overall health, but our lack of understanding of the u...
Nmp4 restricts bone marrow osteoprogenitors and parathyroid hormone induced bone formation in healthy and estrogen depleted female mice
Osteoprogenitor Estrogen depletion
2015/5/21
We have shown that nuclear matrix protein 4 (Nmp4) attenuates the response to intermittent parathyroid hormone (PTH) in healthy and ovariectomized (OVX) female mice using a global knockout of the Nmp4...

Effects of neonatal estrogen administration on rat testis development with particular reference to Sertoli cells
neonatal estrogen administration rat testis development Sertoli cells
2009/2/23
An ultrastructural and morphometric study of the testes in 15-, 22-, 45-, and 90-day-old neonatally estrogenized rats was performed. At 45 days of age, the Sertoli cells appeared immature in estroge...
Impaired estrogen production by Leydig cells of the naturally retained testis in unilaterally cryptorchid boars and stallions
testis cryptorchid boar stallion estrogens
