the present thesis is going to investigate the theme of despair, darkness and pesimism in philip larkins poetry. larkin is a british poet whose poems were composed in the dark and gloomy years of postwar. so, his poetry contains and reflects the same darkness and despair of his age. a good number of poems form different collections of his poetry are chosen and will be analyzed in the light of t...
The immunohistochemistry study made on 30 cases of salivary glands pleomorphic adenomas aims to establish the antigen profile of luminal epithelial neoplastic component proliferates into these tumors. We ascertain that luminal epithelial neoplastic cell were almost exclusively positive to antibody peculiar to epithelial differentiation (AE1/AE3, MNF 116, CK 8, CK 19, CK20, EMA) and occasional t...
We studied cytokeratin (CK) expression immunohistochemically in 64 seminomas using a panel of commercially available antikeratin antibodies and tested for association of CK expression with patient age, tumor size, stage, and outcome. Seventeen embryonal carcinomas were compared with seminoma. CK7, CAM 5.2, AEI/AEIII, and wide-spectrum screening keratin (WSK) were positive in 41%, 30%, 36%, and ...
Distinguishing primary ovarian carcinoma from metastatic carcinoma to the ovary is often difficult by histologic examination alone. Recently an immunohistochemical marker CDX-2 was found to be of considerable diagnostic value in establishing the gastrointestinal origin of metastatic tumors. The aim of this study was to determine whether CDX-2 can distinguish between these malignancies. Paraffin...
Tumor-associated antigens are weakly immunogenic. Human carcinoembryonic antigen (CEA) is overexpressed on a wide range of human carcinomas and represents an attractive target for cancer immunotherapy. This study analyzes the ability of a Saccharomyces cerevisiae vector containing the transgene encoding CEA (yeast-CEA) to activate human dendritic cells (DCs) and stimulate CEA-specific T-cell re...
Carcinoembryonic antigen (CEA) has been reported to promote the metastatic potential in some experimental tumors. Adhesion molecules are known to play an important role in the process of metastasis. Cytokines, including interleukin 1beta (IL-1beta) and tumor necrosis factor-alpha (TNF-alpha), which are produced by Kupffer cells, induce endothelial cells to express adhesion molecules. As a resul...
Despite potentially curative surgery pancreatic cancer has a dismal prognosis. Serum cancer antigen 19-9 (CA 19-9) correlates with tumor burden, resectability and survival in patients with pancreatic ductal adenocarcinoma. Identification of novel biomarkers may facilitate early diagnosis of pancreatic cancer and improve survival. Pancreatic juice is a rich source of cancer-specific proteins ren...
Carcinoembryonic antigen (CEA) is a classic tumor-specific antigen that is overexpressed in several cancers, including gastric cancer. Although some anti-CEA antibodies have been tested, to the best of our knowledge, there are currently no clinically approved anti-CEA antibody therapies. Because of this, we have created the novel anti-CEA antibody, 15-1-32, which exhibits stronger binding to me...
Primary signet-ring cell adenocarcinoma (SRCA) of the lung is very rare. A 78-year-old man consulted to our hospital because of loss of appetite. Physical examination showed lymphadenopathy of the cervical lymph nodes. Chest X-ray showed a tumor of the right upper lobe. Blood laboratory test showed an increase of LDH and CRP. Tumor markers (CYFRA, SCC, CEA, ProGRP) were within normal range. Cli...
Background: The distinction of endometrial adenocarcinoma (EMA) from endocervical (ECA) has great significance preoperatively, since the therapeutic plan depends on primary site tumor. Immunohistochemistry (IHC) is an ancillary method in distinguishing EMA and ECA, especially cases histomorphological overlap. Aims Objectives: Primary objective this study was to describe expression IHC markers–e...
