| Study Title | Effect of external high-dose rate radiation on mouse biofluid metabolomic signatures |
| Study Summary | In the event of an improvised nuclear device (IND), a complex IR exposure will occur consisting of both low (LDR) and high-dose rates (HDR). We have previously addressed LDR exposures from internal emitters or externally deposited radionuclides on biofluid small molecule signatures, but further research on the HDR component is required. Here, we exposed 8 − 10 week old male C57BL/6 mice to a cumulative dose of 3 Gy using a reference dose rate of 0.7 Gy/min or a HDR of 7 Gy/sec, collected urine and serum at 1 and 7 d, then compared the metabolite signatures using either untargeted (urine) or targeted (serum) approaches with liquid chromatography mass spectrometry platforms. |

| MS Comments: | Samples were injected (2 μl) into a Waters Acquity Ultra Performance Liquid Chromatography (UPLC) with a BEH C18 1.7 μm, 2.1 x 50 mm column and coupled to a Xevo® G2-S quadrupole time-of-flight (QTOF) MS (Waters, Milford, MA, USA). Positive and negative electrospray ionization (ESI) data-independent modes were used for data acquisition with leucine enkephalin ([M+H]+ = 556.2771, [M-H]- = 554.2615) as Lock-Spray®. Operating conditions for ESI were: capillary voltage 2.75 kV, cone voltage 30 V, desolvation temperature 500°C, desolvation gas flow 1000 L/Hr. |
