Ovarian tumors are classified on the basis of tumor origin as epithelial tumors (serous and mucinous tumors, endometrioid and clear cell carcinomas, Brenner tumor), germ cell tumors (mature and immature teratomas, dysgerminoma, endodermal sinus tumor, embryonal carcinoma), sex cord-stromal tumors (fibrothecoma; granulosa cell, sclerosing stromal, and Sertoli-Leydig cell tumors), and metastatic ...

The theca interna is a specialized stromal layer that envelops each growing ovarian follicle. It contains capillaries, fibroblasts, immune cells and the steroidogenic cells that synthesize androgens for conversion to estradiol by the neighboring granulosa cells. During reproductive life only a small number of follicles will grow to a sufficient size to ovulate, whereas the majority of follicles...

The in vivo patterns of bak gene expression were determined in human tissues using an immunohistochemical approach. Polyclonal antisera were raised in rabbits against a synthetic peptide corresponding to amino acids 14-36 of the human Bak protein, and were shown to be specific by immunoblot analysis of various human tissues and cell lines. Bak immunoreactivity was detected in a wide variety of ...

Background: The incidence of ovarian masses has increased over the past two decades and is one of the leading causes of cancer-related deaths globally. Although histopathology remains the gold standard, in recent times, imageguided aspiration is being increasingly used as a rapid, inexpensive and efficient method for the pre-operative diagnosis of ovarian masses. The present study was performed...

Peridinium is a genus of freshwater thecate dino¢ agellate. Because it was one of the earliest named genera (Ehrenberg 1832), many species placed in it were later removed to other genera. Genera continue to be extracted and Peridinium, while more closely de› ned, still harbors groups of species unlike the type species, P. cinctum. It is the goal of this paper to remove one of the most dissimila...

Letrozole (Femara; Novartis Pharmaceuticals Corp., East Hanover, NJ) is a nonsteroidal inhibitor of aromatase enzyme complex. It inhibits the peripheral conversion of circulating androgens to estrogens. In postmenopausal women, letrozole decreases plasma concentrations of estradiol, estrone, and estrone sulfate by 75–95% from baseline with maximal suppression achieved within 2–3 days of treatme...
