Aromatase over expression transgenic murine models for aromatase inhibitor studies.
In recent years the emerging importance of estrogen signaling in males in addition to its major role in the female reproductive system became highlighted. Aromatase is the key enzyme for synthesis of estrogens from androgens and is responsible for controlling the androgen/estrogen ratio. Inhibition of aromatase gene expression can be achieved in different ways and is important for the treatment...

هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...
15 صفحه اولAnastrozole: a new selective nonsteroidal aromatase inhibitor.
Aromatase (estrogen synthetase) is the enzyme complex responsible for the final step in estrogen synthesis--the conversion of androstenedione and testosterone to estrone and estradiol, respectively. Inhibitors of this enzyme have been shown to be clinically effective in the treatment of advanced breast cancer in postmenopausal women, in whom the major source of estrogen production derives from ...
متن کاملA new aromatase inhibitor, FR901537. II. Pharmacological and antitumor effects.
The pharmacological and antitumor effects of FR901537, a new aromatase inhibitor, isolated from Bacillus sp. No. 3072, were studied. Treatment for four consecutive days with FR901537 inhibited the androstenedione-induced increase in the uterus weight in immature rats. FR901537 had no effect on the uterus, adrenal glands, ovary or pituitary weights in mature rats following 14 days of treatment. ...
متن کاملAppraising adjuvant aromatase inhibitor therapy.
Tamoxifen, once the gold standard adjuvant endocrine therapy for early breast cancer, is being challenged by third-generation aromatase inhibitors (AIs) that have demonstrated improved disease-free survival in a variety of adjuvant settings for early breast cancer. Tamoxifen and AIs have different safety profiles, which should allow physicians to begin to individualize treatment based on a pati...
