Epidermoid cyst of ovary represents 1% of all surface epithelial tumors. Though we commonly see follicular cyst, simple serous cyst, hemorrhagic cysts in hysterectomy specimens of post menopausal females, epidermoid cyst is an incidental finding. It is necessary to differentiate epidermoid cyst from dermoid cyst and immature teratoma because of different line of treatment. We here report a case...

PURPOSE The aim of this study is to report the clinical features, imaging studies, surgical removal, and pathology of congenital iris flocculi in a patient who developed a life-threatening dissecting aortic aneurysm after 55 years of follow-up. METHODS Documentation with iris photography was performed from age 18 to 55 years, at which time anterior segment optical coherence tomography (OCT) w...

Adenosine, dibutyryl cyclic AMP, monobutyryl cyclic AMP, cyclic AMP, and 5'-AMP have a remarkable morphogenetic effect on cultured iris epithelial cells obtained from adult newt. They alter the broad undulating membrane of the cell into branching strands of cytoplasm, a configuration that has been named "stellate." Theophylline, a phosphodiesterase inhibitor also induces the stellate configurat...

background and aims: ovarian cancer is one of most common causes of cancer related women's mortalities. human papilloma virus is a known factor concerning cervical cancer but its role in causing ovarian cancer is not yet verified. a few studies also identified hpv dna in ovarian carcinoma tissues. however, some studies did not detect hpv dna in ovarian carcinoma tissues. in this article, we inv...

OBJECTIVES To demonstrate that microcontact printing, a modern materials fabrication technique, can be used to engineer the surface of human tissue and to show that inhibitory molecules can be used to pattern the growth of retinal pigment epithelial cells or iris pigment epithelial cells on human lens capsule for transplantation. METHODS Photolithographic techniques were used to fabricate pho...

Autosomal-dominant polycystic kidney disease (ADPKD) is characterized by formation of cysts from tubular epithelial cells. Previous studies indicate that secretion of prostaglandin E2 (PGE2) into cyst fluid and production of cAMP underlie cyst expansion. However, the mechanism by which PGE2 directly stimulates cAMP formation and modulates cystogenesis is still unclear, because the particular E-...

Progressive renal enlargement due to the growth of innumerable fluid-filled cysts is a central pathophysiological feature of autosomal dominant polycystic kidney disease (ADPKD). These epithelial neoplasms enlarge slowly and damage noncystic parenchyma by mechanisms that have not been clearly defined. In a microarray analysis of cultured human ADPKD cyst epithelial cells, periostin mRNA was ove...

BACKGROUND Autosomal dominant polycystic kidney disease (ADPKD) is a common cause of renal failure. Aberrant epithelial cell proliferation is a major cause of progressive cyst enlargement in ADPKD. Since activation of the Ras/Raf signaling system has been detected in cyst-lining epithelia, inhibition of Raf kinase has been proposed as an approach to retard the progression of ADPKD. Methods and ...
