A number of chromosomal abnormalities including 19q deletions have been associated with the formation of human gliomas. In this study, we employed a proteomics-based approach to identify possible genes involved in glioma tumorigenesis which may serve as potential diagnostic molecular markers for this type of cancer. By comparing protein spots from gliomas(More)
Two patients presented with cerebral venous sinus thrombosis (CVST) associated with iron deficiency. A 14-year-old man had thrombosis extending from the end of the superior sagittal sinus to the left transverse sinus. Severe dehydration after competitive sport had induced CVST. The laboratory findings showed severe iron deficiency anemia which persisted for(More)
The Currarino triad is a unique complex of congenital caudal anomalies including anorectal malformation, sacral bone abnormality, and presacral mass. In this report, the authors describe three cases with the complete Currarino triad in a family. The authors treated a 30-year-old mother with an anterior sacral meningocele, her 1-year-old son with a(More)
Treatment of normal human epidermal keratinocytes (NHEK) with interferon-gamma (IFN-gamma) causes a 9-fold increase in the level of cyclooxygenase-2 (COX-2) mRNA expression. Nuclear run-off assays indicate that this induction is at least partly due to increased transcription. Activation of the epidermal growth factor receptor (EGFR) signaling pathway due to(More)
We studied arachidonic acid metabolism and the expression of cyclooxygenase (Cox) and 15-lipoxygenase (15-LO) in the human colorectal carcinoma cell line, Caco-2, which undergo apoptosis and cell differentiation in the presence of sodium butyrate (NaBT). Caco-2 cells expressed very low levels of Cox-1 but highly expressed Cox-2. NaBT treatment shifted the(More)
BACKGROUND It remains open to debate why totally removed benign meningiomas recur. Two recurrent cases forced us to reconsider something corresponding to their recurrence that we had overlooked during Simpson grade I surgery. METHODS This study is based on 24 recent and 9 earlier cases in which benign convexity meningiomas were totally removed by(More)
Histone deacetylase inhibitors that increase histone acetylation on transformed cells are being investigated as unique anticancer drugs. The aim of this investigation was to evaluate an antiproliferative activity of the histone deacetylase inhibitors sodium butyrate (NaBT) and trichostatin A on 5 glioma cell lines, T98G, A172, U-87 MG, U-118 MG, and U-373(More)
For glioblastomas, COX-2 expression is linked to poor survival. COX-2 effects are mediated by the receptors EP2 and EP4, whose regulation is poorly understood. The expression of EP4, and activation or inhibition of EP4 activity in human glioblastoma T98G cells, was found to correlate with growth on soft agar. Chemoprevention drugs, troglitazone (TGZ) and(More)
Whether and when unruptured aneurysms or aneurysmal rests following incomplete surgery result in subsequent bleeding are major concerns for neurosurgeons. By calculating the annual growth rate of aneurysms in long-term follow-up angiography (partly supplemented with MR-imaging and/or MR-angiography), we attempted to determine the surgical indications for(More)
