17 β -Hydroxysteroid dehydrogenase type 1 (17 β -HSD1) catalyzes the conversion of estrone to the potent estrogen estradiol. 17 β -HSD1 is highly expressed in breast and ovary tissues and represents a prognostic marker for the tumor progression and survival of patients with breast cancer and other estrogen-dependent tumors. Therefore, the enzyme is considered a promising drug target against est...

Catamenial epilepsy is a common phenomenon in female epileptic patients that is, in part, influenced by the 17-β-estradiol level during the menstrual cycle, which modulates the strength of the epileptic seizures. However, the underlying mechanism(s) for catamenial epilepsy remains unknown. In the present study, the effect of 17‑β‑estradiol on modulating epileptiform activities was investigated ...

We investigated the effect of high-frequency electromagnetic fields (HF-EMFs) and 17-β-estradiol on connexins (Cxs), integrins (Ints), and estrogen receptor (ER) expression, as well as on ultrastructure of trophoblast-derived HTR-8/SVneo cells. HF-EMF, 17-β-estradiol, and their combination induced an increase of Cx40 and Cx43 mRNA expression. HF-EMF decreased Int alpha1 and β 1 mRNA levels but ...

OBJECTIVE CD4 T-cells secreting interleukin (IL)-17 are implicated in several human autoimmune diseases, but their role in type 1 diabetes has not been defined. To address the relevance of such cells, we examined IL-17 secretion in response to β-cell autoantigens, IL-17A gene expression in islets, and the potential functional consequences of IL-17 release for β-cells. RESEARCH DESIGN AND METH...

Allergic asthma is a complex and chronic inflammatory airway disease. Interleukin-17 is a pro-inflammatory cytokine which plays critical role in the pathogenesis of allergic asthma. It has been reported that β-arrestin2 regulated the development of allergic asthma at a proximal step in the inflammatory cascade. In this study, the influence of β-arrestin2 on Interleukin-17 production and express...

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...

عاملهای شناختی، شخصیتی و موقعیتی متعددی یافت شده است که می توانند با پرخاشگری ارتباط داشته باشند. فهم چگونگی ارتباط درونی این عاملها برای پیش بینی، سنجش، و درمان پرخاشگری زندانیانی که سابقه رفتارهای پرخاشگرانه را دارند، بسیار اساسی است. پژوهشهای قبلی نقش بالقوه ای را برای توانایی حل مساله اجتماعی بعنوان یک میانجیگر بین تکانشگری و پرخاشگری پیشنهاد کرده اند.

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...
