Survivin is a member of the inhibitor of apoptosis family, and is expressed in various malignant tumors. Survivin overexpression has been reported to be a poorer prognostic factor in various malignancies. However, the prognostic value of survivin expression in patients with glioblastoma is still controversial. Therefore, in this study the role of survivin(More)
PURPOSE High linear energy transfer (LET) particles are believed to decrease tumor radiation resistance originating from hypoxia. However, no proof of this effect has been provided by clinical trials and related clinical research. Hence, we investigated the radiation biological aspects of high LET carbon beam therapy on cervical cancer. EXPERIMENTAL(More)
In the present study, we analyzed the possible relationship between interferon (IFN) sensitivity-determining region (ISDR) sequence variation of various hepatitis C virus (HCV) subtypes and serum HCV titers in Indonesian patients without IFN treatment. The viremia titers (mean +/- standard deviation) of HCV subtype 1b (HCV-1b) isolates with low (three or(More)
Manganese Superoxide dismutase (Mn-SOD) inactivates the radiation effect by removal of radiation-induced toxic Superoxide radicals. The purpose of this study was to assess the correlation among Mn-SOD, radiation sensitivity, and prognosis following radiation therapy. higher incidence of local recurrence than those without. However, there was no difference(More)
