Effect of extracorporeal irradiation on segmental bone autograft incorporation in Sprague-Dawley rats
Latar belakang: Autograft tulang digunakan pada operasi rekonstruksi kasus tumor tulang. Extracorporeal irradiation (ECI) pada tulang digunakan untuk membunuh sel tumor. Namun radiasi juga menimbulkan efek negatif terhadap osteoinduksi dan osteogenensis untuk inkorporasi autograft tulang. Penelitian ini bertujuan mempelajari pengaruh iradiasi dengan dosis 50-300 Gy terhadap kemampuan inkorporas...

متن کاملUltra - violet absorption cross sections of isotopically substituted nitrous oxide species : 14 N 14 NO , 15 N 14 NO , 14 N 15 NO and 15 N 15 NO
The isotopically substituted nitrous oxide species 14N14NO, 15N14NO, 14N15NO and 15N15NO were investigated by ultra-violet (UV) absorption spectroscopy. High precision cross sections were obtained for the wavelength range 181 to 218 nm at temperatures of 233 and 283 K. These data are used to calculate photolytic isotopic fractionation constants as a function of wavelength. The fractionation con...
متن کاملFractionation of 14 N 15 N 16 O and 15 N 14 N 16 O During Photolysis at 213 nm
Motivated by Yung and Miller’s suggestion [1997] that N2O is isotopically fractionated during UV photolysis in the stratosphere, we have studied the photolysis rates of the NNO and NNO structural isotopomers. In this study, we follow the concentrations of these compounds with FTIR spectroscopy during photolysis at 213 nm. Our results show that, as Yung and Miller predicted, the photolysis rate ...
