Epstein-Barr virus (EBV) infects various cell types in a wide spectrum of benign and malignant diseases. Laboratory tests for EBV have improved and are increasingly used in diagnosis, prognosis, prediction, and prevention of diseases ranging from infectious mononucleosis to selected subtypes of lymphoma, sarcoma, and carcinoma. Indeed, the presence of EBV(More)
Previous reports have shown that the biochemical activity of heparanase is significantly correlated with the invasion and metastasis of malignant cells in vitro. Recently, it was found that the human heparanase gene was cloned and highly expressed in malignant cell lines and human solid malignant tumors. In the present study, we investigated the heparanase(More)
Epstein-Barr virus (EBV) infects cells in latent or lytic forms, but the role of lytic infection in EBV-induced lymphomas is unclear. Here, we have used a new humanized mouse model, in which both human fetal CD34(+) hematopoietic stem cells and thymus/liver tissue are transplanted, to compare EBV pathogenesis and lymphoma formation following infection with(More)
Disruption of ionic homeostasis and neuronal hyperexcitability contribute to early brain injury after subarachnoid hemorrhage (SAH). The hyperpolarization-activated/cyclic nucleotide (HCN)-gated channels play critical role in the regulation of neuronal excitability in hippocampus CA1 region and neocortex, in which the abnormal neuronal activities are more(More)
Epstein-Barr virus (EBV) DNA measurement is being incorporated into routine medical practice to help diagnose, monitor, and predict posttransplant lymphoproliferative disorder (PTLD) in immunocompromised graft recipients. PTLD is an aggressive neoplasm that almost always harbors EBV DNA within the neoplastic lymphocytes, and it is often fatal if not(More)
Papillary thyroid carcinoma frequently metastasizes to regional lymph nodes, and lymph node metastasis increases the risk of local regional relapse. Recent evidence suggests that vascular endothelial growth factor-D (VEGF-D) promotes lymphangiogenesis, which in turn promotes lymphatic metastasis. Therefore, the role of VEGF-D messenger RNA transcript levels(More)
Programmed cell death is an important determinant of the response to chemotherapy. Among the factors controlling this process, a significant role is played by bcl-2, bax and p53. The in vitro chemosensitivity of the 177 breast carcinomas was assessed by the histoculture drug response assay (HDRA) using mitomycin C (MMC), 5-fluorouracil (5-Fu), adriamycin(More)
Epstein-Barr Virus (EBV) is found in 10% of all gastric adenocarcinomas but its role in tumor development and maintenance remains unclear. The objective of this study was to examine EBV-mediated dysregulation of cellular factors implicated in gastric carcinogenesis. Gene expression patterns were examined in EBV-negative and EBV-positive AGS gastric(More)
OBJECTIVE To describe the phenomenon of parathyroid gland involvement by thyroid carcinoma and to explore its clinicopathologic significance. DESIGN We reviewed the clinicopathologic features and described the histopathologic characteristics of 20 cases of parathyroid involvement found in a series of 911 papillary thyroid carcinomas. RESULTS Parathyroid(More)
