BACKGROUND Breast cancer grows in a hormone-rich environment which influences its biological features and thus, ultimately, its clinical behavior. Circulating hormone levels were measured in premenopausal and postmenopausal breast cancer patients prior to surgery, and correlated with all available clinical and biological features of the tumors and with serum tumor marker levels. MATERIALS AND...

background and objective: the association of ebv with hodgkin lymphoma (hl) has been intensely investigated over the last few years. ebv is also associated with several other malignancies. on the other hand, ki67 molecule serves as a widely accepted proliferation marker. several studies were previously performed about the expression of ki67 in hd. this study tried to detect the correlation betw...

Urothelial carcinoma of the bladder in childhood is extremely rare. We report on a 12-year-old girl with urothelial carcinoma of the bladder who presented with gross hematuria. Immunohistochemical staining showed normal levels of cytokeratin 20 expression and decreased levels of Ki67 and p53 expression. Human papillomavirus, which can be a cause of urothelial carcinoma of the bladder, was not d...

The effect of first synthesized dipeptide L-Leu-Lys was studied on cell proliferation and apoptosis using the organotypic culture of spleen tissue from 3-mont-old rats. The dipeptide at concentrations in diapason 0.001 -10 ng/ml produce a clearly defined stimulating effect on cell proliferation in these tissues, accompanying by an increase of expression of Ki67 and decrease of P53 expression. O...

The present study aimed to synthesize new metal complexes of diacetylmonoxime-N(4)antipyrinylthiosemicarbazone ligand and evaluate their antitumor activity. New with ferric, cobalt, nickel copper ions were prepared. Elemental, 1H Nuclear magnetic resonance, Mass spectroscopy, Electron paramagnetic Fourier Transform Infrared Spectroscopy, Ultraviolet–visible thermal gravimetric analysis used cha...

This report describes two cases of sebaceous epithelioma and its immunohistochemical characterization with CK 14, CK18, p63, Ki67 and Bcl-2 immunostaining. Case 1 was a 12-year-old, intact English Cocker spaniel female presenting with multiple skin nodules over one year. Case 2 was a 7-year-old, spayed poodle female with a five-month history of solitary mass. Hematoxylin and eosin (H&E) stainin...
