the correlation between serum steroid hormones, testosterone (t), 17β-estradiol (e2), and progesterone (p) and weight of female fishes, biological characteristics of gonad (e.g. fertilization rate, fluid egg rate, gonadosomatic index , polarization index and oocyte diameter) in 10 female of the migratory population of sterlet (acipenser ruthenus) and 5 female of the migratory population of sibe...

conclusions it appears that fenugreek seed might be effective against hyperglycemia, hyperlipidemia and insulin resistance in ovariectomized rats without impact on serum apelin. furthermore, 17-β estradiol could have similar effects along with possible inhibitory effects on serum apelin. the complicated role of apelin in menopause needs to be further explored. results serum apelin, glucose, lip...

where the spectral index β is related to p through β = − 2 . β ∼ −3 is observed at microwave frequencies. The linear polarization fraction is at most (in a uniform ~ B field) fs = p+1 p+7/3 ∼ 0.75 for β ∼ −3. The parameter C indicates possible deviations from a pure power-law. Of course, all this is dependent on the position on the sky, i.e one really has Ts(ν0, n̂), β(n̂), C(n̂). The polarization...

The present study was carried out with the objective of evaluating, in castrated rats, utero trophic, hormonal and biochemical activities aqueous extracts Buchholzia coriacea (BC) Cogniauxia podolaena (CP) leaves. Each extract administered at dose 600 mg/Kg rats did not cause a significant change fresh weight/dry weight ratio uterus compared to given distilled water. However, those receiving 17...

Background & Aims: Adult neurogenesis occurs in the two main areas of the brain of most mammalian species in; sub ventricular zone, and the dentate gyrus of the hippocampus. Many factors such as 17-β estradiol affect neurogenesis in the hippocampus. The aim of this study was to investigate the effect of exogenous 17-β estradiol on neurogenesis in the ovariectomized (OVX) mice. Materials & Meth...

The purpose of this in vitro study was to assess the effect of 17β-estradiol on hemorheologic parameters, namely on erythrocyte aggregation and deformability and membrane fluidity. Blood samples from 65 women (aged 57±4 years) undergoing postmenopausal hormone replacement therapy were obtained and were incubated for 5 min in absence and presence of 17β-estradiol 10−5 M. The measured parameters ...

the most important characteristics of ptsd, as an anxiety disorder, are memory disorders and hippocampus is one of the essential structures which plays a critical role in ptsd memory disorders. traumatic events cause apoptosis and alter the expression of neurotrophic factors in hippocampus. the aim of this study is to evaluate the effects of β-estradiol on behavioral responses in ptsd and to st...

Steroids promote the myelination and regeneration in the peripheral nervous system. Whereas, little is known about the inducing effects by which the hormones exert their effects on Schwann cells differentiation. This could be revealed by the expression of Schwann cell markers in adipose-derived stem cells (ADSCs). The purpose of this study was to present the effects of progesterone and 17 β-est...
