WebJul 30, 2024 · Using time-lapse imaging, we found that HT could delay and decrease the formation of 53BP1 IR-induced foci (IRIF). Moreover, through the in situ tracking of individual IRIF, it was observed that HT resulted in more unrepaired IRIF over the period of observation compared with treatment with IR alone. Additionally, the unrepaired IRIF had … WebWhat does IRIF abbreviation stand for? List of 12 best IRIF meaning forms based on popularity.
