epithelial tumors are rarely seen during the first two decades of life. we report a 17 year old male with primary transitional cell carcinoma (tcc) of the bladder.

Epithelial cell adhesion molecule 1 (EpCAM) is an epithelial membrane glycoprotein, often used as a surrogate pan-epithelial marker. To compare the expression patterns of EpCAM and pankeratin antibody (CKpan), gold standard detection, tissue microarrays containing 11,053 samples from 101 different tumor types were analysed by immunohistochemistry. staining was detectable in 99 (82.5%) 120 tumou...

purpose : studies show that phenytoin is effective in improvement of different chronic ulcers such as venous stasis ulcers, and diabetic ulcers. the exact mechanism is yet not clear investigators thought that phenytoin might help to heal intractable corneal ulcers by reducing inflammation, differentiating limbal fibroblasts, and promoting the invasion of the cornea with new blood vessels as sho...

objective(s): endometriosis is a complex gynecologic disease with unknown etiology. noscapine has been introduced as a cancer cell suppressor. endometriosis was considered as a cancer like disorder, the aim of present study was to investigate noscapine apoptotic effect on human endometriotic epithelial and stromal cells in vitro. materials and methods:in this in vitro study, endometrial biopsie...

purpose: to separate and characterize orbital fat-derived stem cells (ofscs) and compare its cellular and molecular properties with those of bone marrow-derived mesenchymal stem cells (mscs) and adipose-derived stem cells (ascs). methods: stem cells from orbital fat, abdominal fat and bone marrow aspirates have been isolated. we assessed stem cell specific cell surface markers using cytometry, ...

tears have antimicrobial, nourishing, mechanical, and optical properties and contain components such as growth factors, fibronectin and vitamins to support proliferation, migration and differentiation of corneal and conjunctival epithelial cells. lack of these epitheliotrophic factors, as in dry eye, can result in severe ocular surface disorders such as persistent epithelial defects. recently, ...

among oral lesions, we encounter a series of malignant epithelial lesions that go through clinical and histopathologic processes in order to be diagnosed. identifying these processes along with the etiology knowledge of these lesions is very important in prevention and early treatments. dysplasia is the step preceding the formation of squamous cell carcinoma in lesions which have the potential ...

introduction : the proto-oncogene her2 plays a key role in the control of cellular proliferation. its overexpression has been reported to be associated with a poor prognosis in cancer, particularly in breast cancer. materials and methods : in the present study, serum her2 levels were investigated in patients diagnosed with epithelial ovarian cancer. serum her2 levels were detected by an elisa c...
