The prognostic value of various molecular markers, which adequately account for the tumor biology and disease behaviour of ovarian cancer, is still unclear. Recent studies have focused on the role of genes regulating the balance between proliferation and cellular suicide, apoptosis. In the present study, tumor tissue from 215 patients with ovarian cancer(More)
Drug resistance is one of the most important clinical problems in the treatment of ovarian cancer. This study was designed to determine whether expression of p53 could be used as a marker for predicting the response to chemotherapy of ovarian cancer. Tissue blocks were obtained from 187 patients with diagnosed untreated ovarian cancer. Paraffin sections(More)
Understanding how users perceive 3D geometric objects can provide a basis for creating more effective tools for visualization in applications such as CAD or medical imaging. This article examines how orientation indicators affect users' accuracy in perceiving the shape of a 3D object shown as multiple views. Multiple views force users to infer the(More)
Understanding the shape of 3D objects is particularly significant in scientific visualization and CAD/CAM applications, however objective measurements of how various rendering techniques affect object perception has not received enough attention. We propose a methodology which uses the Vandenberg and Kuse [1978] mental rotation paradigm as a mechanism for(More)
Standardization of (153)Sm by 4π(LS)-γ coincidence and anticoincidence counting and the CIEMAT/NIST method in three LS-counters is presented. This short half-life radionuclide is applied in tumor therapy and bone pain palliation. A simplified disintegration scheme of (153)Sm was applied in the calculation of the counting efficiency. Standard uncertainties(More)
A new 4π(LS)-γ coincidence system (TDCRG) was built at the NCBJ RC POLATOM. The counter consists of a TDCR detector in the beta channel and scintillation detector with NaI(Tl) crystal in the gamma channel. The system is equipped with a digital board with FPGA, which records and analyses coincidences in the TDCR detector and coincidences between the beta and(More)
