DNA-dependent protein kinase catalytic subunit (DNA-PKcs), Ku80, and ataxia-telangiectasia mutated (ATM) are the most important repair proteins of DSB. Cervical carcinoma is mainly treated by radiotherapy; however, the tumor cells display different radiosensitivity. This study tried to explore the correlations of DNA-PKcs, Ku80, and ATM expression to radiosensitivity of cervical cancer cells, and to probe their potentials in enhancing the radiosensitivity of cervical carcinoma. The expression of DNA-PKcs, Ku80, and ATM in 41 specimens of cervical carcinoma was detected by immunohistochemistry. Their expression in 8 tumor cell lines (including 4 cervical carcinoma cell lines) was measured by Western blot; the survival fraction at 2 Gy (SF2) and alpha value were measured by colony formation test; the correlations of protein expression to SF2 and alpha values were analyzed by Pearson linear correlation analy...

Cracking phenomenon was taken place during cold forging of ML25Mn steel. In this study, microstructural analyses were made on the cracked regions of the steel. The reason of cracking phenomenon occurring during cold forging for ML25Mn steel was investigated based on SEM observation in detail. The results have shown that ML25Mn steel presents lower strength and toughness. A larger amount of inclusions which are composed of MnS and complex oxides containing Mg, Al, Mn, Fe, S, Ca and O are found, and the complex inclusion might be brought during the deoxidation and the solidification in smelting and casting. Non-metallic inclusions result in significant stress concentration, which cause cracking phenomenon occurring during cold forging of ML25Mn steel.
