The effect of donor age and low-dose gamma irradiation on the initial biomechanical properties of human tibialis tendon allografts.
BACKGROUND Most tissue banks recover and irradiate tibialis tendon allografts from donors aged up to 65 years. It is unknown whether donor age and low-dose gamma irradiation affect the initial biomechanical properties of tibialis allografts. HYPOTHESIS Donor age up to 65 years and low-dose gamma irradiation do not significantly affect the initial biomechanical properties of tibialis allograft...
متن کاملGamma Irradiated Soft Tissue Allografts are Biomechanically Equivalent to Aseptic, Non-Sterilized Tissues
Allograft safety is contingent on effective sterilization methods such as gamma irradiation. However, recent clinical studies have associated gamma irradiation with decreased graft strength and increased allograft failure rates, despite data that shows no deleterious effects to soft tissue biomechanics at gamma doses between 1.46 and 2.18 mRad. The objective of this study was to compare the bio...
متن کاملWater radiolysis by gamma –irradiation for high quality synthesis of Nickel Oxide nano sheet
A simple, time effective and cost effective, methos was reported for synthesis of nickel oxide nanostructure. The NiO nanostructure was synthesized by gamma-irradiation method from NiSO4 precursor. The solution was irradiated by 60Co gamma-ray source at the dose rate of 40 Gy/min for determined time. The synthesized powders are characterized by means of X-ray powder diffraction (XRD), Energy-di...
متن کاملHIGH LATITUDE GAMMA RAYS ASSOCIATED WITH VIRGO
A more detailed analysis is made of the energy spectrum of the diffuse component of extragalactic gamma rays over the range of 0.3- 10 GeV, obtained fromthe EGRET instrument at the Compton Gamma Ray Observatory. The derived excess energy spectrum of high galactic latitude, b > 60°, using intercept method shows that it is correlated with Virgo cluster (over lsr) and average Virgo intensity i...
متن کاملSoft-tissue allografts terminally sterilized with an electron beam are biomechanically equivalent to aseptic, nonsterilized tendons.
BACKGROUND Allograft safety is contingent on effective sterilization. However, current sterilization methods have been associated with decreased biomechanical strength and higher failure rates of soft-tissue allografts. In this study, electron beam (e-beam) sterilization was explored as an alternative sterilization method to preserve biomechanical integrity. We hypothesized that e-beam steriliz...
