background and aims. vascular endothelial growth factor (vegf) and ki-67 antigen are contributing factors in this process cell proliferation and new blood vessels formation in tumor progression. this study was conducted to examine the relationship between the expression of vegf and ki-67 and gender and age of patients with oral squamous cell carcinoma (oscc). materials and methods. twenty-three...

objective(s) the aim of this study was to evaluate the expressions of two angiogenic immune-markers (cd-31 and vegf), and one proliferative immune-marker (ki-67) in oral pyogenic granulomas (pg), hemangiomas (hem) and inflammatory gingivitis (ig). materials and methods sixty cases of pg, hem and ig (twenty cases each) were examined. immunohistochemical (ihc) staining was performed based on rout...

objectives : squamous cell carcinoma (scc) is the most common malignant neoplasm of the oral cavity and a public health threat. tumor progression is believed to be influenced by angiogenesis as well as tumor cell proliferation; however, the correlation of these two factors in tongue scc still remains unclear. this study aimed to assess the correlation of these two factors in tongue scc. materia...

background and objective: evaluation of tumor proliferative activity may provide a predicting parameter to estimate biologic aggression and a subsequent prognosis that has been evaluated in many malignancies. we have selected renal cell carcinoma (rcc) in this study. to determine tumor proliferative activity, ki67 antibody was applied and results were compared with apoptosis, applying p53 antib...

meningiomas are slow-growing neoplasms which recur locally, their morphologic grading is simple but do not always correlate with patient outcome. the aim of present study is to evaluate the status of progesterone receptor (pr) and proliferation marker ki67 in various grades of meningioma in a group of iranian patients. 78 cases of meningioma were selected from the file of a hospital university....

introdouction: lichen planus is a chronic, relatively common, dermal mucosa disease. the world health organization (who) has introduced lichen planus as a premalignant condition. ki-67 is a protein that can be detected in all active phases of the cell cycle, especially in the g2 and m phases. considering the major role of ki-67 in the regulation of the cell cycle and the fact that it is one of ...

background and objectives: uterine smooth muscle tumors are the most common human neoplasm .they are divided clinically as benign and malignant but there is  another group of  lesions which is difficult to place in these two categories ,so-called smooth  muscle tumors of uncertain malignant potential (stump) and differentiation  of these tumors on the basis of h&e staining is impossible . t...

I present Quillen’s proof of the fact that the K-groups KiA where A is the ring of integers in a number field F are finitely generated. This talk was given in the Algebraic K-theory seminar at Michigan during the Winter semester of 2015.

statement of problem: odontogenic keratocysts (okc) make up 10-12% of all developmental cysts with dental origin. okcs are classified into parakeratotic and orthokeratotic types, with completely different clinical features. in order to investigate biological behavior of okcs, an immunohistochemical study was designed, using ki-67 antigen as proliferation marker and p53 protein as tumor suppress...
